Fourteen microsatellite loci of Phoenix dactylifera were targeted to examine the genetic diversity in Tunisian date-palms germplasm. They showed a high level of polymorphism in 49 accessions from three main oases with little geographic structure within Tunisia. The microsatellite data agrees with previous analyses of Tunisian germplasm using other molecular markers. 100% of local date-palms accessions were successfully fingerprinted and easily distinguished by the help of only three loci. The possibility of using microsatellites for large scale molecular labelling of offshoots and in vitro plantlets and their implication in the plant material certification is discussed.

Oocyte maturation arrest (OMA) may occur at different stages, including the germinal vesicle (GV), metaphase I (MI), and metaphase II (MII). A total maturation arrest of human oocytes is rarely observed during fertilization (IVF). We have identified a case of infertile female for whom all oocytes fail to mature and are arrested at MI.

Monkeypox virus (MPXV) is an important zoonotic pathogenic virus, which poses serious threats to public health. MPXV infection can be prevented by immunization against the variola virus. Because of the safety risks and side effects of vaccination with live vaccinia virus (VACV) strain Tian Tan (VTT), we constructed two gene-deleted VTT recombinants (TTVAC7 and TTVC5).

Benign prostatic hyperplasia (BPH) is a prevalent urinary system disorder. Despite evidence of a significant genetic component from previous studies, the specific pathogenic genes and biological mechanisms are still largely unknown. The study utilized the FinnGen R10 dataset, encompassing 177,901 individuals (36,601 cases and 141,300 controls), and the GTEx v8 EQTLs files to conduct single-tissue and cross-tissue transcriptome-wide association studies (TWAS).

Previous studies have found that dyslipidemia is a risk factor for pancreatic cancer (PC), and that lipid-lowering drugs may reduce the risk of PC. However, it is not clear whether dyslipidemia causes PC. The Mendelian randomization (MR) study aimed to investigate the causal role of lipid traits in pancreatic cancer and to assess the potential impact of lipid-lowering drug targets on pancreatic cancer.
