Objectives: Periodontitis is an inflammatory disease characterized by connective tissue loss and alveolar bone destruction. Interleukin-8 (IL8) is important in the regulation of the immune response. The aim of this study was to analyze four polymorphisms in the IL8 gene in relation to chronic (CP) and aggressive (AgP) periodontitis.
Methods: A total of 492 unrelated subjects were included in this case-control association study. Genomic DNA of 278 patients with CP, 58 patients with AgP, and 156 controls were genotyped, using the 5' nuclease TaqMan assay, for IL8 (rs4073, rs2227307, rs2227306, and rs2227532) gene polymorphisms. Subgingival bacterial colonization was investigated by the DNA-microarray detection kit in a subgroup of subjects (N = 247).
Results: Allele and genotype frequencies of all investigated IL8 polymorphisms were not significantly different between the subjects with CP and/or AgP and controls (P > 0.05). Nevertheless, the A(-251)/T(+396)/T(+781) and T(-251)/G(+396)/C(+781) haplotypes were significantly less frequent in patients with CP (2.0% versus 5.1%, P < 0.02, OR = 0.34, 95% CI: 0.15-0.78, resp., 2.0% versus 4.5%, P < 0.05, OR = 0.41, 95% CI: 0.18-0.97) than in controls.
Conclusions: Although none of the investigated SNPs in the IL8 gene was individually associated with periodontitis, some haplotypes can be protective against CP in the Czech population.

Background: There are no studies belong NOTCH2 gene polymorphism in relation to reproductive and productive traits in Holstein cattle. The objective of the present study was to investigate the effect of NOTCH2 gene polymorphisms on productive and reproductive performance of fertile and anestrum cattle.
Methods: The cattle were classified into anestrus for 3-12 months postpartum (n = 115, 37.

Objectives: Associations of ABO blood group specifying transferases A/B (ABO) and fucosyltransferase 2 (FUT2) with CP remain inconclusive. We aimed to comprehensively investigate the associations by Chinese sequencing cohorts and external cohorts.
Methods: First, we analyzed the distributions of ABO blood groups and FUT2 status, along with lead single nucleotide polymorphisms (SNPs) at ABO (rs8176693 C/T) and FUT2 (rs632111 A/G) gene loci in Chinese low-coverage whole-genome sequencing discovery cohort.
CYP19 and ESR2 polymorphisms as potential culprits in cryptorchidism.

Introduction: Cryptorchidism impairs sperm development and increases the risk of infertility and testicular cancer. Estrogen signalling is critical for proper descent of the testicles, and hormonal imbalances play a role in cryptorchidism. CYP19, also known as aromatase, encodes an enzyme that converts testosterone, a male sex hormone, into estradiol, the main form of estrogen.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide and a major global health concern. In the United States (US), individuals of Black or African American racial identity experience disproportionately higher rates of TBI and suffer from worse post-injury outcomes. Contemporary research agendas have largely overlooked or excluded Black populations, resulting in the continued marginalization of Black patient populations in TBI studies, thereby limiting the generalizability of ongoing research to patients in the US and around the world.

Introduction: The genetic complexity of Plasmodium falciparum is contributory to the emergence of drug resistant-parasites. Intermittent preventive treatment of malaria in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) in malaria endemic settings is recommended by WHO. This study evaluated the prevalence of Plasmodium falciparum multidrug resistance-1 gene (Pfmdr-1), genetic diversity of merozoite surface proteins (msp-1, msp-2) and glutamate-rich protein (glurp) among pregnant women with sub-patent parasitaemia from southwest Nigeria.
