The association, in different ethnic groups, of apolipoprotein E (apoE) gene polymorphism with mild cognitive impairment (MCI) has been unclear. Few studies have examined the association in Chinese minorities. The current study explores the association between apoE gene polymorphism and MCI in one of the biggest ethnic groups-the Hui-and compares it with the Han. The Minimental State Exam, Activities of Daily Living Scale, and Geriatric Depression Scale were administered to 306 ethnic Hui and 618 ethnic Han people aged ≥55 years. ApoE genotypes were determined using the high resolution melting curve method. The distribution of the apoE genotype and the frequency of alleles ε2, ε3, and ε4 were similar in the Hui and Han groups. In analyses adjusted for age, gender, and education level, the ε4 allele was a risk factor for MCI in both the Hui group (OR = 2.61, 95% CI: 1.02-6.66) and the Han group (OR = 2.36, 95% CI: 1.19-4.67), but the apoE ε2 allele was protective for MCI only in the Han group (OR = 0.48, 95% CI: 0.38-0.88). The association of some apoE genotypes with MCI may differ in different ethnic groups in China. Further studies are needed to explore this effect among different populations.

Objective: Osteoarthritis (OA) represents a condition under the influence of central nervous system (CNS) regulatory mechanisms. This investigation aims to examine the causal association between viral infections of the central nervous system (VICNS) and inflammatory diseases of the central nervous system (IDCNS) and knee osteoarthritis (KOA) at the genetic level.
Methods: In this investigation, VICNS and IDCNS were considered as primary exposure variables, while KOA served as the primary outcome.

Twin studies have suggested extremely high estimates of heritability for adolescent executive function, with no substantial contributions from shared environment. However, developmental psychology research has found significant correlations between executive function outcomes and elements of the environment that would be shared in twins. It is unclear whether these seemingly contradictory findings are best explained by genetic confounding in developmental studies or limitations in twin studies, which can potentially underestimate shared environment.

Introduction: A continuing challenge for malaria control is the ability of to develop resistance to antimalarial drugs. Members within the transcription factor family AP2 regulate the growth and development of the parasite, and are also thought to be involved in unclear aspects of drug resistance. Here we screened for single nucleotide polymorphisms (SNPs) within the AP2 family and identified 6 non-synonymous mutations within AP2-06B (PF3D7_0613800), with allele frequencies greater than 0.

The cystathionine beta-synthase (CBS) gene plays a critical role in numerous physiological processes, including cellular proliferation, bioenergetics, and redox balance, and has been implicated in many cancers, including breast and gastric cancers. Previous studies have suggested that VNTR polymorphism in intron 13 of the CBS gene may influence enzyme activity, as an increase in the number of repeats in this VNTR leads to a reduction in the activity of the CBS enzyme. In this case-control study, for the first time, we genotyped 107 patients with gastric cancer (and 111 healthy controls) and 138 patients with breast cancer (and 124 healthy controls) for the CBS VNTR polymorphism using PCR.

Single Nucleotide Polymorphisms (SNPs) have found it be associated with drug resistance in epilepsy. The purpose of this study was to determine the role of SCN1A gene polymorphism in developing drug resistance in idiopathic generalized epilepsy (IGE) patients, along with increased oxidative stress. The study was conducted at a tertiary care hospital in Delhi, India.
