Summary: Genomic analysis of UPEC isolates from UTI patients in Saudi Arabia identified the most common sequence types as ST131 (39.6%), ST1193 (12.5%), ST73 (10.4%), and ST10 (8.3%). The majority of ESBL isolates carried the bla(CTX-M-15) gene (79.2%), followed by bla(CTX-M-27) (12.5%) and bla(CTX-M-8) (2.1%). The relatively high proportion of ST1193 in this study is noteworthy as a newly emerged lineage in the region, which requires further monitoring.

Summary: This study aimed to investigate the association between killer cell immunoglobulin-like receptors (KIR) genes polymorphisms and HLA-I ligands with COVID-19 in Saudi Arabia. Genotyping of 16 KIR genes, HLA-C1 and C2 allotypes, and HLA-G 14-bp indels polymorphisms was performed using the SSP-PCR method in 87 COVID-19 patients and 114 healthy controls. The study found that the frequencies of KIR2DL2 and KIR2DL4 genes were higher in COVID-19 positive patients, and the combination of KIR2DL2-HLA-C2 was significantly more common in COVID-19 patients compared to healthy controls.

Summary: This study evaluated the anti-cancer effects and cellular mechanisms of queen bee acid (10-Hydroxy-2-Decenoic Acid, 10-HDA) on the human hepatoma cell line HepG2. The results showed that 10-HDA significantly reduced the viability of HepG2 cells, induced apoptosis, and upregulated the expression of apoptosis-related genes and proteins. These findings confirmed the potent cytotoxic effects of 10-HDA on HepG2 cells with no significant toxicity on normal cells.

Summary: This study evaluated the chemical composition and therapeutic effects of Curcuma zedoaria essential oil (CZEO) compared to metronidazole (MTZ) for Giardia lamblia infection treatment. In vitro and in vivo experiments showed that CZEO reduced the viability of G. lamblia cysts and trophozoites, and decreased the number and viability of excreted cysts. The highest reduction of Giardia antigen was observed in mice treated with CZEO. These findings highlight the potential therapeutic effects of CZEO on Giardia infections.

Summary: The green synthesized silver nanoparticles (SNP) showed promising acaricidal, larvicidal, and repellent activity against Hyalomma dromedarii ticks. SNP dose-dependently increased the mortality rate of adult ticks and reduced the viability rate of larvae. Additionally, SNP decreased the level of acetylcholinesterase and antioxidant activity, and induced oxidative stress in larvae.
