Gene polymorphism of 3'APO-VNTR in Egyptians with coronary artery disease

Background

Coronary artery diseases (CAD) are big health problem in both developed and developing countries. It is considered one of the main causes of death in the world. Dyslipidemia increases the risk of CAD incidences. It is aimed in this worktop study the impact of 3'APOBVNTRgene on CAD incidences.

Methods

Eighty CAD patients and ninety-three healthy volunteers are enrolled in this study. Lipid parameters were estimated in both groups and PCR technique has been performed to analyze 3'APOB-VNTR gene polymorphism.

Results

The genotypes 31/31, 31/37, 37/37 and 31/44 are more predominant in both groups. The frequency of 24/31 in CAD patients is (0.137) while it is completely absent in the control group. Our results show that there is an increase in the frequency of various genotypes (e.g., 17/31 and 21/34 genotypes) in the control group compared to theca patients group.

Conclusions

3'APOB-VNTR gene could probably be considered a risk factor for CAD incidences and may help to early diagnose them.

Serum perfluoroalkyl substances in relation to lipid metabolism in Chinese pregnant women

Laboratory and epidemiologic studies suggested that exposure to perfluoroalkyl substances (PFASs) could affect lipid metabolisms, but data remain limited for pregnant women. A total of 436 pregnant women were selected in Tangshan City, North China. Serum levels of 11 PFASs were determined in the early term of pregnancy. Four lipids (total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL)) were measured in the late term of pregnancy. Of 11 PFASs, seven had a detection rate of greater than 70%. After adjusting for potential confounders, natural log-transformed perfluororohexanesulfonic acid (ln PFHxS) was positively associated with TC (β: 0.184, 95% CI: 0.045-0.321), HDL (β: 0.040, 95% CI: 0.001-0.083), and LDL (β: 0.091, 95% CI: 0.001-0.185). Ln perfluoroundecanoic acid (PFUdA) was positively associated with HDL (β: 0.021, 95% CI: 0.001-0.044), while Ln perfluorodecanoic acid (PFDA) was negatively associated with LDL (β: -0.053, 95% CI: -0.098∼-0.009) and ln perfluorootanoic acid (PFOA) was negatively associated with LDL/HDL (β: -0.042, 95% CI: -0.075∼-0.009). In principal component analysis, the component with a large loading of 31.3% for PFOA, perfluorononanoic acid (PFNA), PFDA and PFUdA showed a negative association with LDL/HDL. After serum concentrations of PFASs were categorized into quartiles, a higher level of TC was seen in the second quartile of PFOA or PFNA than the first quartile, but a lower LDL/HDL ratio was seen in the fourth quartile of PFOA, PFUdA or PFDA. These results suggested that exposure to PFASs has a potential to influence lipid metabolisms in pregnant women.

Lipid profile, random blood glucose and carotid arteries thickness in human male subjects with different ages and body mass indexes

OBJECTIVE

This article investigated the effect of age and body mass index of male humans on the carotid arteries intima media thickness (IMT) and the blood concentration of glucose, triglycerides, total cholesterol and HDL cholesterol.

METHODS

Thirty seven normal male human subjects participated in this study. The participants were classified to three groups depending on their age; 20-29 (11), 30-39 (14) and 40-49 (12). Also, the study subjects were divided to three groups according to their body mass index; normal (13), overweight (13) and obese (11). The Anova test was used for the statistical analysis of the obtained results.

RESULTS

The body mass index significantly affected the blood glucose concentration while its effect on all the other parameters was insignificant. The age significantly affected all the studied parameters except the blood glucose, triglycerides and HDL cholesterol. The total cholesterol/HDL ratio was significantly affected by the age and insignificantly by the body mass index.

CONCLUSIONS

The age was more effective on the studied parameters than the body mass index. Worsening of the lipid profile was seen in the overweight participants rather than the obese ones.
