Apolipoprotein (apo) E4 is the major genetic risk factor for Alzheimer's disease (AD). ApoE4 has sex-dependent effects, whereby the risk of developing AD is higher in apoE4-expressing females than males. However, the mechanism underlying the sex difference, in relation to apoE4, is unknown. Previous findings indicate that apoE4 causes age-dependent impairments of hilar GABAergic interneurons in...

HE pattern of distribution of bristles in Drosophila melanogaster is under 'genic control. Thus, the first tarsal segment of a foreleg of female genotype does not differentiate the row of heavy bristles which constitutes a sex comb while this structure is formed on a foreleg of male genotype. The determination of the sex comb was studied by STERN and HANNAH (1950) by means of analysis of gynand...

A polymorphism in the serotonin transporter gene (5-HTTLPR) is frequently studied for association with antidepressant treatment response, different personality traits, and psychiatric disorders. Baseline platelet serotonin (5-HT) concentration has been proposed to indicate a good or a poor treatment response to antidepressant drugs and to be associated with particular symptoms in psychiatric di...

The interindividual variation in ApoE plasma concentration is considerable, mainly determined by apoE genotype and sex. However, a large amount of variability remains unexplained by these factors. We have evaluated whether the quantity and quality of dietary fat interacts with the apoE genotype and sex modifying ApoE plasma levels in young healthy subjects. Eighty-four volunteers (sixty-six apo...

BACKGROUND We compare the genotype distribution for the serotonin transporter polymorphism (5-HTTLPR) in a sample of older Taiwanese adults with samples of various racial and ethnic groups collected in other studies. We also explore interactions among sex, stressors, and 5-HTTLPR genotype on depressive symptoms in our sample. METHODS Using a nationally representative sample of 984 Taiwanese a...

OBJECTIVE To evaluate the association between Haptoglobin (HP) gene polymorphisms with inflammatory status in obese subjects. MATERIALS AND METHODS A cross-sectional study was carried out. A total of 276 apparently healthy men and nonpregnant obese women were enrolled and allocated according to the HP genotype into the HP (1)/HP (1), HP (2)/HP (1), and HP (2)/HP (2) groups. Distribution of HP...

BACKGROUND/AIM To investigate the distribution of viral genotypes, the extrahepatic manifestations, and the relationship between genotypes and extrahepatic manifestations in patients with chronic hepatitis C. MATERIALS AND METHODS The study included 62 treatment-naive patients with chronic hepatitis C infection. Genotype determination was performed by DNA sequencing analysis. To investigate e...

Background: Varicella zoster virus (VZV) causes chickenpox in children and zoster (zona) in the elderly. Using RFLP-PCR method for detection of VZV specific SNPs ORF38, 54 and 62 could  distinguish the profile of VZV isolates. The aim of this study was to investigate enzymatic digestion pattern of VZV ORF38 and ORF54 in chickenpox patients using RFLP technique. <b...
