Animals in the control group received an AIN-93 M diet, and animals in the experimental group received an Atkins-based diet(59.46% protein, 31.77% fat, and 8.77% carbohydrate). After 8 wk, the rats were anesthetized and exsanguinated for transaminases analysis, and their livers were removed for flow cytometry, immunohistochemistry, and light microscopy studies. We expressed the data as mean ± standard deviation(sd) assuming unpaired and parametric data; we analyzed differences using the student's t-test. statistical significance was set at P < 0.05.RESULTS: We found that plasma alanine aminotransferase and aspartate aminotransferase levels were significantly higher in the experimental group than in the control group. According to flow cytometry, the percentages of nonviable cells were 11.67% ± 1.12% for early apoptosis, 12.07% ± 1.11% for late apoptosis, and 7.11% ± 0.44% for non-apoptotic death in the experimental diet group and 3.73% ± 0.50% for early apoptosis, 5.67% ± 0.72% for late apoptosis, and 3.82% ± 0.28% for non-apoptotic death in the control diet group. The mean percentage of early apoptosis was higher in the experimental diet group than in the control diet group. Immunohistochemistry for autophagy was negative in both groups. sinusoidal dilation around the central vein and small hepatocytes was only observed in the experimental diet group, and fibrosis was not identified by hematoxylin-eosin or Trichrome Masson staining in either group.CONCLUSION: Eight weeks of an experimental diet resulted in cellular and histopathological lesions in rat livers. Apoptosis was our principal finding; elevated plasma transaminases demonstrate hepatic lesions.展开更多

L-carnitine motivated group showed significant body weight loss and a decrement of serum triglyceride level vs. the non-motivated placebo group. Serum adiponectin levels increased in both L-carnitine supplemented groups. The beneficial effects of L-carnitine were amplified by motivation training. For clinical evaluation of supplements, whose efficacy is potentially affected by inter-individual life style variability, supportive motivation training might be advisable for future clinical trials.展开更多

The aim of this study was to compare the effect of specific or general fish consumption recommendations on fish intake behavior over the duration of a 12-month clinical trial. Participants were randomized into a control group (general dietary advice), and two intervention groups (received dietetic advice to consume 180 g fish/wk), with one intervention group receiving LC omega-3 PUFA supplements. Dietary data was available for n = 117 at baseline, n = 85 at 3 months and n = 63 at 12 months. Total, fatty and lean fish intake (g/day) was calculated, and the change in fish intake between and within groups over the duration of the study was measured. Total fish consumption did not differ significantly between groups or within groups, however fatty fish intake was significantly greater in the intervention groups at three months (p = 0.004). The proportion of study participants complying with fish intake recommendations was also highest at the three month time point for both intervention groups. Overall, compliance to fish intake recommendations was highest at the three month time point and appeared to be influenced by dietetic intervention. Provision of fish may increase compliance in future studies, however if research is to be translated to practice, behavioral approaches are required to increase fish intake in the long term.展开更多

Aim: The objective of this study is to determine the prevalence of iron deficiency anemia and its associated factors during pregnancy in the south of Morocco. Methods: A cross-sectional study was carried in the regional Hospital Center Hassan II (RHC) from April to august 2021 in all the pregnant women coming for consultation in the maternity service. 500 pregnant women were randomly recruited for the study. A complete blood count and serum ferritin was performed in every case. They have been the subjects of a questionnaire containing their background and health data. The analysis of our data was done by the IBM SPSS Statistics 25 software. Results: The prevalence of iron deficiency anemia was 20% with a CI of (44.7% - 53.5%). The most affected age group was 25 to 35 years with a rate of 42.86%. The majority of women had mild anemia (84.61%) followed by moderate anemia (11.54%) and severe anemia (3.85%). 57.14% of the anemic pregnant women were primigravida. The results of serum ferritin made it possible to identify 70% of women deficient, with a dominance of normocytic normochromic anemia. The influence of geographic origin and place of birth was not significant. Conclusion: The prevalence of iron deficiency anemia is more or less low in our study. However, there is a high prevalence of iron deficiency and anemia during pregnancy. Statistically, there was no significant association between iron deficiency anemia and the various parameters studied, such as age, parity, origin and place of birth.展开更多
