Environmental contamination and developmental abnormalities in eggs and hatchlings of the common snapping turtle (Chelydra serpentina serpentina) from the Great Lakes-St Lawrence River basin (1989-1991).

Furthermore, sestrin2 induction is implicated in autophagy activation, and knockdown of sestrin2 prevented enhanced cell viability by gAcrp.

During the pandemic, people with opioid use disorder (OUD) were not only at elevated risk for COVID-19, but had markedly reduced access to treatment for OUD, Hepatitis C virus (HCV) and HIV due to recommended decreased in-person visits. METHODS: From March 15-June 15, 2020 at the syringe services program (SSP) in New Haven, Connecticut, USA, a differentiated care model evolved with reduced clinical demands on people who inject drugs (PWID) to ensure screening and treatment for HCV, HIV and OUD, with a focus on HCV treatment. This model involved a single, bundled screening, evaluation, testing (SET) and monitoring strategy for all three conditions, minimal in-person visits, followed by tele-health communication between patients, outreach workers and clinicians. In-person visits occurred only during induction onto methadone and phlebotomy at baseline and phlebotomy 12 weeks post-treatment for HCV to measure sustained virological response (SVR). Patients received supportive texts/calls from outreach workers and clinicians. RESULTS: Overall, 66 actively injecting PWID, all with OUD, underwent bundled laboratory screening; 35 had chronic HCV infection. Participants were 40 years (mean), mostly white (N = 18) men (N = 28) and 12 were unstably housed. Two were lost to-follow-up and 2 were incarcerated, leaving 31 who started pan-genotypic direct-acting antivirals (DAAs). The mean time from referral to initial phlebotomy and initiation of DAAs was 6.9 and 9.9 days, respectively. Fourteen additional patients were newly started on buprenorphine and 6 started on methadone; three and four, respectively, were on treatment at baseline. Overall, 29 (93.5%) PWID who initiated DAAs achieved SVR; among unstably housed persons the SVR was 83.3%. CONCLUSIONS: In response to COVID-19, an innovative differentiated care model for PWID at an SSP evolved that included successful co-treatment for HCV, HIV and OUD using a client-centered approach that reduces treatment demands on patients yet supports ongoing access to evidence-based treatments." ], "offsets": [ [ 223, 2424 ] ] } ]

Treatment of Hepatitis C virus among people who inject drugs at a syringe service program during the COVID-19 response: The potential role of telehealth, medications for opioid use disorder and minimal demands on patients. BACKGROUND: Healthcare delivery was disrupted during the COVID-19 pandemic, requiring minimized in-person contact between patients and clinicians. During the pandemic, people with opioid use disorder (OUD) were not only at elevated risk for COVID-19, but had markedly reduced access to treatment for OUD, Hepatitis C virus (HCV) and HIV due to recommended decreased in-person visits. METHODS: From March 15-June 15, 2020 at the syringe services program (SSP) in New Haven, Connecticut, USA, a differentiated care model evolved with reduced clinical demands on people who inject drugs (PWID) to ensure screening and treatment for HCV, HIV and OUD, with a focus on HCV treatment. This model involved a single, bundled screening, evaluation, testing (SET) and monitoring strategy for all three conditions, minimal in-person visits, followed by tele-health communication between patients, outreach workers and clinicians. In-person visits occurred only during induction onto methadone and phlebotomy at baseline and phlebotomy 12 weeks post-treatment for HCV to measure sustained virological response (SVR). Patients received supportive texts/calls from outreach workers and clinicians. RESULTS: Overall, 66 actively injecting PWID, all with OUD, underwent bundled laboratory screening; 35 had chronic HCV infection. Participants were 40 years (mean), mostly white (N = 18) men (N = 28) and 12 were unstably housed. Two were lost to-follow-up and 2 were incarcerated, leaving 31 who started pan-genotypic direct-acting antivirals (DAAs). The mean time from referral to initial phlebotomy and initiation of DAAs was 6.9 and 9.9 days, respectively. Fourteen additional patients were newly started on buprenorphine and 6 started on methadone; three and four, respectively, were on treatment at baseline. Overall, 29 (93.5%) PWID who initiated DAAs achieved SVR; among unstably housed persons the SVR was 83.3%. CONCLUSIONS: In response to COVID-19, an innovative differentiated care model for PWID at an SSP evolved that included successful co-treatment for HCV, HIV and OUD using a client-centered approach that reduces treatment demands on patients yet supports ongoing access to evidence-based treatments.

Similarities between action potentials and acoustic pulses in a van der Waals fluid. An action potential is typically described as a purely electrical change that propagates along the membrane of excitable cells. However, recent experiments have demonstrated that non-linear acoustic pulses that propagate along lipid interfaces and traverse the melting transition, share many similar properties with action potentials. Despite the striking experimental similarities, a comprehensive theoretical study of acoustic pulses in lipid systems is still lacking. Here we demonstrate that an idealized description of an interface near phase transition captures many properties of acoustic pulses in lipid monolayers, as well as action potentials in living cells. The possibility that action potentials may better be described as acoustic pulses in soft interfaces near phase transition is illustrated by the following similar properties: correspondence of time and velocity scales, qualitative pulse shape, sigmoidal response to stimulation amplitude (an 'all-or-none' behavior), appearance in multiple observables (particularly, an adiabatic change of temperature), excitation by many types of stimulations, as well as annihilation upon collision.

Minimally invasive tube placement is facilitated through one of two techniques, push or pull, but there have been conflicting results regarding safety profiles of these procedures. The objectives of this study were to determine the association of PEG insertion technique with gastrostomy tube complications, including stomal metastases. METHODS: A multi-institutional retrospective cohort study of patients with HNC undergoing PEG insertion by either the pull (gastroscope assisted) or push (fluoroscopy assisted) technique was performed. Tube-related complications included infection, dislodgement, deterioration, leak, and other. Adjusted analysis was performed via a multivariable logistic regression model. RESULTS: 1,575 patients were included across three institutions. Tube-related complications occurred in 36% of patients, the most common being peristomal leak (13%) and infection (16%). The push technique (OR 2.66, 95% CI: 1.42-4.97), and the presence of T4 disease (OR 4.62, 95% CI: 1.58-13.51), were associated with a greater risk of developing any tube-related complication. Infection rates were similar between pull and push cohorts. All detected stoma metastases occurred with the pull technique, with an overall prevalence of 0.32% amongst the cohort.

Placement technique impacts gastrostomy tube-related complications amongst head and neck cancer patients. OBJECTIVES: Percutaneous endoscopic gastrostomy (PEG) placement is essential for the provision of enteral nutrition in select head and neck cancer (HNC) patients. Minimally invasive tube placement is facilitated through one of two techniques, push or pull, but there have been conflicting results regarding safety profiles of these procedures. The objectives of this study were to determine the association of PEG insertion technique with gastrostomy tube complications, including stomal metastases. METHODS: A multi-institutional retrospective cohort study of patients with HNC undergoing PEG insertion by either the pull (gastroscope assisted) or push (fluoroscopy assisted) technique was performed. Tube-related complications included infection, dislodgement, deterioration, leak, and other. Adjusted analysis was performed via a multivariable logistic regression model. RESULTS: 1,575 patients were included across three institutions. Tube-related complications occurred in 36% of patients, the most common being peristomal leak (13%) and infection (16%). The push technique (OR 2.66, 95% CI: 1.42-4.97), and the presence of T4 disease (OR 4.62, 95% CI: 1.58-13.51), were associated with a greater risk of developing any tube-related complication. Infection rates were similar between pull and push cohorts. All detected stoma metastases occurred with the pull technique, with an overall prevalence of 0.32% amongst the cohort. CONCLUSIONS: The push technique is associated with a greater risk of developing any tube-related complication, but the rate of stomal metastases may be higher with the pull technique. There is potential for quality improvement measures to improve tube-related complications associated with either technique.

Over 50% of deaths among diabetic patients are caused by cardiovascular diseases. Cardiac diastolic dysfunction is one of the key early signs of diabetic cardiomyopathy, which often occurs before systolic dysfunction. However, no drug is currently licensed for its treatment. METHODS: Type 9 adeno-associated virus combined with cardiac Troponin T promoter were employed to manipulate miR-21 expression in the leptin receptor-deficient (db/db) mice. Cardiac structure and functions were measured by echocardiography and hemodynamic examinations. Primary cardiomyocytes and cardiomyocyte cell lines were used to perform gain/loss-of-function assays in vitro. RESULTS: We observed a significant reduction of miR-21 in the diastolic dysfunctional heart of db/db mice. Remarkably, delivery of miR-21 efficiently protected against the early impairment in cardiac diastolic dysfunction, represented by decreased ROS production, increased bioavailable NO and relieved diabetes-induced cardiomyocyte hypertrophy in db/db mice. Through bioinformatic analysis and Ago2 co-immunoprecipitation, we identified that miR-21 directly targeted gelsolin, a member of the actin-binding proteins, which acted as a transcriptional cofactor in signal transduction. Moreover, down-regulation of gelsolin by siRNA also attenuated the early phase of diabetic cardiomyopathy. CONCLUSION: Our findings reveal a new role of miR-21 in attenuating diabetic cardiomyopathy by targeting gelsolin, and provide a molecular basis for developing a miRNA-based therapy against diabetic cardiomyopathy." ], "offsets": [ [ 102, 1751 ] ] } ]

MiR-21 protected against diabetic cardiomyopathy induced diastolic dysfunction by targeting gelsolin. BACKGROUND: Diabetes is a leading cause of mortality and morbidity across the world. Over 50% of deaths among diabetic patients are caused by cardiovascular diseases. Cardiac diastolic dysfunction is one of the key early signs of diabetic cardiomyopathy, which often occurs before systolic dysfunction. However, no drug is currently licensed for its treatment. METHODS: Type 9 adeno-associated virus combined with cardiac Troponin T promoter were employed to manipulate miR-21 expression in the leptin receptor-deficient (db/db) mice. Cardiac structure and functions were measured by echocardiography and hemodynamic examinations. Primary cardiomyocytes and cardiomyocyte cell lines were used to perform gain/loss-of-function assays in vitro. RESULTS: We observed a significant reduction of miR-21 in the diastolic dysfunctional heart of db/db mice. Remarkably, delivery of miR-21 efficiently protected against the early impairment in cardiac diastolic dysfunction, represented by decreased ROS production, increased bioavailable NO and relieved diabetes-induced cardiomyocyte hypertrophy in db/db mice. Through bioinformatic analysis and Ago2 co-immunoprecipitation, we identified that miR-21 directly targeted gelsolin, a member of the actin-binding proteins, which acted as a transcriptional cofactor in signal transduction. Moreover, down-regulation of gelsolin by siRNA also attenuated the early phase of diabetic cardiomyopathy. CONCLUSION: Our findings reveal a new role of miR-21 in attenuating diabetic cardiomyopathy by targeting gelsolin, and provide a molecular basis for developing a miRNA-based therapy against diabetic cardiomyopathy.

Numerous studies have indicated the association between Copper (Cu) and ceruloplasmin (Cp) concentrations and pathogenesis of RA. OBJECTIVE: To compare the concentrations of Cu and Cp in different biological samples and their correlation with the inflammatory process, between a group of patients with RA and a control group of healthy individuals. MATERIALS AND METHODS: The study enrolled 74 Caucasian patients (20 men and 54 women), aged 29-50 (mean age 39.8+-6.1 years) diagnosed with RA. The control group consisted of 30 healthy Caucasian individuals. Copper levels were assessed by atomic absorption spectroscopy. RESULTS: Among RA patients the mean Cu level was significantly higher in serum and hair compartments and significantly lower in erythrocytes, compared with the control group (p<0.01). The Cp concentration was also higher in serum of RA patients (p<0.001). A statistically significant, positive correlation between the Cp serum concentration and the ESR values (r(s)=0.38; p<0.007) was found. No significant influence of pharmaceutical treatment (methotrexate, non-steroidal anti-inflammatory drugs, glucocorticoids, calcium, vitamin D3 and sulphasalazine) on serum Cu was found. CONCLUSIONS: It seems that the 'copper status' in patients with RA, based on the measurement of Cu and Cp levels in blood serum is correlated with presence of the inflammatory process. The hair could serve as a useful, additional diagnostic material. Some other factors, different from the applied treatment, can probably influence the Cu levels in patients with RA." ], "offsets": [ [ 53, 1752 ] ] } ]

Copper levels in patients with rheumatoid arthritis. INTRODUCTION: Rheumatoid arthritis (RA) is a chronic, autoimmune-based disease of the connective tissue with still unknown etiology. Numerous studies have indicated the association between Copper (Cu) and ceruloplasmin (Cp) concentrations and pathogenesis of RA. OBJECTIVE: To compare the concentrations of Cu and Cp in different biological samples and their correlation with the inflammatory process, between a group of patients with RA and a control group of healthy individuals. MATERIALS AND METHODS: The study enrolled 74 Caucasian patients (20 men and 54 women), aged 29-50 (mean age 39.8+-6.1 years) diagnosed with RA. The control group consisted of 30 healthy Caucasian individuals. Copper levels were assessed by atomic absorption spectroscopy. RESULTS: Among RA patients the mean Cu level was significantly higher in serum and hair compartments and significantly lower in erythrocytes, compared with the control group (p<0.01). The Cp concentration was also higher in serum of RA patients (p<0.001). A statistically significant, positive correlation between the Cp serum concentration and the ESR values (r(s)=0.38; p<0.007) was found. No significant influence of pharmaceutical treatment (methotrexate, non-steroidal anti-inflammatory drugs, glucocorticoids, calcium, vitamin D3 and sulphasalazine) on serum Cu was found. CONCLUSIONS: It seems that the 'copper status' in patients with RA, based on the measurement of Cu and Cp levels in blood serum is correlated with presence of the inflammatory process. The hair could serve as a useful, additional diagnostic material. Some other factors, different from the applied treatment, can probably influence the Cu levels in patients with RA.

However, Ca2+ release sites that did not initially activate or which have prematurely recovered from refractoriness might release Ca2+ later during the action potential and alter the cell-wide Ca2+ transient. OBJECTIVE: To investigate the possibility of late Ca2+ spark (LCS) activity in intact isolated cardiac myocytes using fast confocal line scanning with improved confocality and signal to noise. METHODS AND RESULTS: We recorded Ca2+ transients from cardiac ventricular myocytes isolated from rabbit hearts. Action potentials were produced by electric stimulation, and rapid solution changes were used to modify the L-type Ca2+ current. After the upstroke of the Ca2+ transient, LCSs were detected which had increased amplitude compared with diastolic Ca2+ sparks. LCS are triggered by both L-type Ca2+ channel activity during the action potential plateau, as well as by the increase of cytosolic Ca2+ associated with the Ca2+ transient itself. Importantly, a mismatch between sarcoplasmic reticulum load and L-type Ca2+ trigger can increase the number of LCS. The likelihood of triggering an LCS also depends on recovery from refractoriness that appears after prior activation. Consequences of LCS include a reduced rate of decline of the Ca2+ transient and, if frequent, formation of microscopic propagating Ca2+ release events (Ca2+ ripples). Ca2+ ripples resemble Ca2+ waves in terms of local propagation velocity but spread for only a short distance because of limited regeneration. CONCLUSIONS: These new types of Ca2+ signaling behavior extend our understanding of Ca2+-mediated signaling. LCS may provide an arrhythmogenic substrate by slowing the Ca2+ transient decline, as well as by amplifying maintained Ca2+ current effects on intracellular Ca2+ and consequently Na+/Ca2+ exchange current." ], "offsets": [ [ 87, 2083 ] ] } ]

Late Ca2+ Sparks and Ripples During the Systolic Ca2+ Transient in Heart Muscle Cells. RATIONALE: The development of a refractory period for Ca2+ spark initiation after Ca2+ release in cardiac myocytes should inhibit further Ca2+ release during the action potential plateau. However, Ca2+ release sites that did not initially activate or which have prematurely recovered from refractoriness might release Ca2+ later during the action potential and alter the cell-wide Ca2+ transient. OBJECTIVE: To investigate the possibility of late Ca2+ spark (LCS) activity in intact isolated cardiac myocytes using fast confocal line scanning with improved confocality and signal to noise. METHODS AND RESULTS: We recorded Ca2+ transients from cardiac ventricular myocytes isolated from rabbit hearts. Action potentials were produced by electric stimulation, and rapid solution changes were used to modify the L-type Ca2+ current. After the upstroke of the Ca2+ transient, LCSs were detected which had increased amplitude compared with diastolic Ca2+ sparks. LCS are triggered by both L-type Ca2+ channel activity during the action potential plateau, as well as by the increase of cytosolic Ca2+ associated with the Ca2+ transient itself. Importantly, a mismatch between sarcoplasmic reticulum load and L-type Ca2+ trigger can increase the number of LCS. The likelihood of triggering an LCS also depends on recovery from refractoriness that appears after prior activation. Consequences of LCS include a reduced rate of decline of the Ca2+ transient and, if frequent, formation of microscopic propagating Ca2+ release events (Ca2+ ripples). Ca2+ ripples resemble Ca2+ waves in terms of local propagation velocity but spread for only a short distance because of limited regeneration. CONCLUSIONS: These new types of Ca2+ signaling behavior extend our understanding of Ca2+-mediated signaling. LCS may provide an arrhythmogenic substrate by slowing the Ca2+ transient decline, as well as by amplifying maintained Ca2+ current effects on intracellular Ca2+ and consequently Na+/Ca2+ exchange current.

Here, we examined the role of Cr(III)-DNA adducts in mutagenesis induced by metabolism of Cr(VI) with cysteine. Reduction of Cr(VI) caused a strong oxidation of 2', 7'-dichlorofluoroscin (DCFH) and extensive Cr-DNA binding but no DNA breakage. Cr-DNA adducts induced unwinding of supercoiled plasmids and structural distortions in the DNA helix as detected by decreased ethidium bromide binding. Propagation of Cr-treated pSP189 plasmids in human fibroblasts led to a dose-dependent formation of the supF mutants and inhibition of replication. Blocking of Cr(III)-DNA binding by occupation of DNA phosphates with Mg(2+) or by sequestration of Cr(III) by inorganic phosphate or EDTA eliminated mutagenic responses and restored a normal yield of replicated plasmids. Dissociation of Cr(III) from DNA by a phosphate-based reversal procedure returned mutation frequency to background levels. The mutagenic responses at the different phases of the reduction reaction were unrelated to the amount of reduced Cr(VI) but reflected the number and the spectrum of Cr(III)-DNA adducts that were formed. Ternary cysteine-Cr(III)-DNA adducts were approximately 4-5 times more mutagenic than binary Cr(III)-DNA adducts. Although intermediate reaction products (CrV/IV, thiyl radicals) were capable of oxidizing DCFH, they were insufficiently reactive to damage DNA. Single-base substitutions at G/C pairs were the predominant type of Cr-induced mutations. The majority of mutations occurred at the sites where G had adjacent purine in the 3' or 5' position. Overall, our results present the first evidence that Cr(III)-DNA adducts play the dominant role in the mutagenicity caused by the metabolism of Cr(VI) by a biological reducing agent." ], "offsets": [ [ 174, 2064 ] ] } ]

Non-oxidative mechanisms are responsible for the induction of mutagenesis by reduction of Cr(VI) with cysteine: role of ternary DNA adducts in Cr(III)-dependent mutagenesis. Intracellular reduction of carcinogenic Cr(VI) generates Cr-DNA adducts formed through the coordination of Cr(III) to DNA phosphates (phosphotriester-type adduct). Here, we examined the role of Cr(III)-DNA adducts in mutagenesis induced by metabolism of Cr(VI) with cysteine. Reduction of Cr(VI) caused a strong oxidation of 2', 7'-dichlorofluoroscin (DCFH) and extensive Cr-DNA binding but no DNA breakage. Cr-DNA adducts induced unwinding of supercoiled plasmids and structural distortions in the DNA helix as detected by decreased ethidium bromide binding. Propagation of Cr-treated pSP189 plasmids in human fibroblasts led to a dose-dependent formation of the supF mutants and inhibition of replication. Blocking of Cr(III)-DNA binding by occupation of DNA phosphates with Mg(2+) or by sequestration of Cr(III) by inorganic phosphate or EDTA eliminated mutagenic responses and restored a normal yield of replicated plasmids. Dissociation of Cr(III) from DNA by a phosphate-based reversal procedure returned mutation frequency to background levels. The mutagenic responses at the different phases of the reduction reaction were unrelated to the amount of reduced Cr(VI) but reflected the number and the spectrum of Cr(III)-DNA adducts that were formed. Ternary cysteine-Cr(III)-DNA adducts were approximately 4-5 times more mutagenic than binary Cr(III)-DNA adducts. Although intermediate reaction products (CrV/IV, thiyl radicals) were capable of oxidizing DCFH, they were insufficiently reactive to damage DNA. Single-base substitutions at G/C pairs were the predominant type of Cr-induced mutations. The majority of mutations occurred at the sites where G had adjacent purine in the 3' or 5' position. Overall, our results present the first evidence that Cr(III)-DNA adducts play the dominant role in the mutagenicity caused by the metabolism of Cr(VI) by a biological reducing agent.

We hypothesized that at least some of the spectrum of phenotypes could be explained by placing the disorder into a developmental and genetic context. Thirty-eight percent of the population had Kallmann syndrome (KS; IHH with anosmia), 54% had normosmic IHH, and 8% had acquired IHH after completion of puberty.

The purpose of this study was to test the hypothesis that reactive hyperemia is the mechanism responsible for stimulating mTORC1 signaling and MPS following BFR exercise. Six young men (24 +- 2 yr) were used in a randomized crossover study consisting of two exercise trials: low-intensity resistance exercise with BFR (BFR trial) and low-intensity resistance exercise with sodium nitroprusside (SNP), a pharmacological vasodilator infusion into the femoral artery immediately after exercise to simulate the reactive hyperemia response after BFR exercise (SNP trial). Postexercise mixed-muscle fractional synthetic rate from the vastus lateralis increased by 49% in the BFR trial (P < 0.05) with no change in the SNP trial (P > 0.05). BFR exercise increased the phosphorylation of mTOR, S6 kinase 1, ribosomal protein S6, ERK1/2, and Mnk1-interacting kinase 1 (P < 0.05) with no changes in mTORC1 signaling in the SNP trial (P > 0.05).

Reactive hyperemia is not responsible for stimulating muscle protein synthesis following blood flow restriction exercise. Blood flow restriction (BFR) to contracting skeletal muscle during low-intensity resistance exercise training increases muscle strength and size in humans. However, the mechanism(s) underlying these effects are largely unknown. We have previously shown that mammalian target of rapamycin complex 1 (mTORC1) signaling and muscle protein synthesis (MPS) are stimulated following an acute bout of BFR exercise. The purpose of this study was to test the hypothesis that reactive hyperemia is the mechanism responsible for stimulating mTORC1 signaling and MPS following BFR exercise. Six young men (24 +- 2 yr) were used in a randomized crossover study consisting of two exercise trials: low-intensity resistance exercise with BFR (BFR trial) and low-intensity resistance exercise with sodium nitroprusside (SNP), a pharmacological vasodilator infusion into the femoral artery immediately after exercise to simulate the reactive hyperemia response after BFR exercise (SNP trial). Postexercise mixed-muscle fractional synthetic rate from the vastus lateralis increased by 49% in the BFR trial (P < 0.05) with no change in the SNP trial (P > 0.05). BFR exercise increased the phosphorylation of mTOR, S6 kinase 1, ribosomal protein S6, ERK1/2, and Mnk1-interacting kinase 1 (P < 0.05) with no changes in mTORC1 signaling in the SNP trial (P > 0.05). We conclude that reactive hyperemia is not a primary mechanism for BFR exercise-induced mTORC1 signaling and MPS. Further research is necessary to elucidate the cellular mechanism(s) responsible for the increase in mTOR signaling, MPS, and hypertrophy following acute and chronic BFR exercise.

[Recent problems of advanced age in humans. I. General problems]. The obvious increase of human age even up to above one hundred years in nearly all civilised countries leeds the autor to discuss the following actual gerontologic problems: the needs for further splitting of categories of high age, the reasons for the rapid increase of the oldest-old group and the predicted "mushroom"-shaped age-pyramid in Germany. Further subjects are the liability of age-declaration in the highest age group according to the strict directions by Kannisto, the total account of men and women above one hundred years of age in different countries and in Germany since 1963, the difference between relative and absolute longevity and new molecular-biologic and genetic studies on extreme age.

In addition, we examined whether weekly vitamin A and iron supplementation was more efficacious than weekly supplementation with iron alone. One group of pregnant women (n = 122)was supplemented weekly with iron (120 mg Fe as FeSO4) and folic acid (500 microg); another group (n = 121) received the same amount of iron and folic acid plus vitamin A [4800 retinol equivalents (RE)]. A third (\"daily\") group (n = 123), participating in the national iron plus folic acid supplementation program, was also recruited. Data on subjects with complete biochemical data are reported (n = 190). At near term, hemoglobin concentrations increased, whereas serum ferritin concentrations decreased significantly in the weekly vitamin A and iron group, suggesting that vitamin A improved utilization of iron for hematopoiesis. Iron status in the weekly iron group was not different from that of the \"daily\" group. However, iron status decreased with daily supplementation if <50 iron tablets were ingested. Serum transferrin receptor concentrations increased in all groups (P < 0.01). Serum retinol concentrations were maintained in the weekly vitamin A and iron group, but decreased in the other two groups (P < 0.01). Thus, delivery of iron supplements on a weekly basis can be as effective as ona daily basis if compliance can be ensured.

Weekly supplementation with iron and vitamin A during pregnancy increases hemoglobin concentration but decreases serum ferritin concentration in Indonesian pregnant women. We investigated whether weekly iron supplementation was as effective as the national daily iron supplementation program in Indonesia in improving iron status at near term in pregnancy. In addition, we examined whether weekly vitamin A and iron supplementation was more efficacious than weekly supplementation with iron alone. One group of pregnant women (n = 122)was supplemented weekly with iron (120 mg Fe as FeSO4) and folic acid (500 microg); another group (n = 121) received the same amount of iron and folic acid plus vitamin A [4800 retinol equivalents (RE)]. A third ("daily") group (n = 123), participating in the national iron plus folic acid supplementation program, was also recruited. Data on subjects with complete biochemical data are reported (n = 190). At near term, hemoglobin concentrations increased, whereas serum ferritin concentrations decreased significantly in the weekly vitamin A and iron group, suggesting that vitamin A improved utilization of iron for hematopoiesis. Iron status in the weekly iron group was not different from that of the "daily" group. However, iron status decreased with daily supplementation if <50 iron tablets were ingested. Serum transferrin receptor concentrations increased in all groups (P < 0.01). Serum retinol concentrations were maintained in the weekly vitamin A and iron group, but decreased in the other two groups (P < 0.01). Thus, delivery of iron supplements on a weekly basis can be as effective as ona daily basis if compliance can be ensured. Addition of vitamin A to the supplement improved hemoglobin concentration.

Influence of maternal characteristics and caregiving behaviours on children's caries experience: An intergenerational approach. OBJECTIVES: This study adopted an intergenerational approach, aiming to answer the following research questions: (a) Are maternal oral health-related behaviours and oral health associated with dental caries in preschool children?; (b) Do maternal caregiving behaviours mediate the association between maternal oral health-related behaviours and dental caries in preschool children. METHODS: Children aged 5 years, enrolled in the 2004 Pelotas (Brazil) Birth Cohort, were investigated (n = 1303). Children were dentally examined using WHO criteria to assess the number of decayed, missing and filled surfaces (dmfs), and their mothers were interviewed. Standardized direct, indirect and total effects of maternal characteristics (frequency of toothbrushing, dental anxiety, the pattern of dental attendance, self-perception about oral health and self-reported dental caries) on maternal caregiving behaviours and children's dmfs were assessed using path analysis. RESULTS: Mean dmfs was 4.1 (95% CI 3.6;4.5). Maternal oral health-related behaviours had no direct effect on children's dental caries: child dental attendance pattern partially mediates the effect of maternal dental attendance pattern on dental caries (87.8%; P < 0.05) and partially mediates the effect of maternal dental anxiety (39.9%; P < 0.001).

CONCLUSIONS: Socioeconomic factors directly influenced children's caries experience, whereas maternal oral health-related behaviours had no direct effect. It was observed an indirect effect of maternal dental anxiety and dental attendance pattern on children's dental caries mediated by caregiving behaviours, such as child dental attendance pattern and frequency of toothbrushing.

Vaccination of domestic ruminants is taking place throughout Europe to control BT expansion. The high density of wild red deer (Cervus elaphus) in some European regions has raised concerns about the potential role that unvaccinated European wild ungulates might play in maintaining or spreading the virus. Most species of wild ruminants are susceptible to BTV infection, although frequently asymptomatically. The red deer population density in Europe is similar to that of domestic livestock in some areas, and red deer could account for a significant percentage of the BTV-infection susceptible ruminant population in certain regions. High serum antibody prevalence has been found in red deer, and BTV RNA (BTV-1, BTV-4 and BTV-8) has been repeatedly detected in naturally infected European red deer by means of RT-PCR. Moreover, red deer may carry the virus asymptomatically for long periods. Epidemiological studies suggest that there are more BT cases in domestic ungulates in those areas where red deer are present. Vector and host density and environmental factors are implicated in the spatial distribution of BT. As in domestic ruminants, BTV transmission among wild ruminants depends almost exclusively on Culicoides vectors, mainly C. imicola but also members of the C. obsoletus and C. pulicaris complex. However, BTV transmission from red deer to the vector remains to be demonstrated. Transplacental, oral, and mechanical transmissions are also suspected. Thus, wild red deer contribute to the still unclear epidemiology of BTV in Europe, and could complicate BTV control in domestic ruminants. However, further research at the wildlife host-vector-pathogen interface and regarding the epidemiology of BT and BT vectors in wildlife habitats is needed to confirm this hypothesis. Moreover, red deer could be used as BT sentinels.

By using biologically active CCMV cDNA clones, we find that deletions in either RNA3 gene block systemic infection. Thus, though some plant RNA viruses are able to spread systemically without encapsidation, both the coat and 3a genes are required for systemic infection of cowpeas by CCMV. When plants were coinoculated with CCMV RNAs 1 and 2 and both the 3a and coat deletion mutants of RNA3, 30-60% rapidly developed systemic infection. Progeny RNA recovered from systemically infected leaves in such infections contained neither of the starting deletion mutants but rather a single full-length RNA3 component with both genes intact. Nucleotide substitutions introduced into the coat protein deletion mutant as an artificial marker were recovered in the full-length progeny RNA, confirming its recombinant nature.

Regeneration of a functional RNA virus genome by recombination between deletion mutants and requirement for cowpea chlorotic mottle virus 3a and coat genes for systemic infection. RNAs 1 and 2 of the tripartite cowpea chlorotic mottle virus (CCMV) genome are sufficient for RNA replication in protoplasts, whereas systemic infection of cowpea plants additionally requires RNA3, which encodes the 3a noncapsid protein and coat protein. By using biologically active CCMV cDNA clones, we find that deletions in either RNA3 gene block systemic infection. Thus, though some plant RNA viruses are able to spread systemically without encapsidation, both the coat and 3a genes are required for systemic infection of cowpeas by CCMV. When plants were coinoculated with CCMV RNAs 1 and 2 and both the 3a and coat deletion mutants of RNA3, 30-60% rapidly developed systemic infection. Progeny RNA recovered from systemically infected leaves in such infections contained neither of the starting deletion mutants but rather a single full-length RNA3 component with both genes intact. Nucleotide substitutions introduced into the coat protein deletion mutant as an artificial marker were recovered in the full-length progeny RNA, confirming its recombinant nature. Intermolecular RNA recombination in planta can, therefore, rescue a complete infectious genome from coinoculated mutants independently disabled for systemic spread. These results have implications for the repair of defective genomes produced by frequent natural replication errors, the possible emergence of newly adapted RNA viruses upon coinfection of new hosts, and further studies of RNA virus recombination.
