In this study, we investigated the F1 antibody against in the sera of mother-neonate shepherd dog pairs in the plague focus of the Altun-Qilian Mountains, Qinghai-Tibetan Plateau, China. Seropositive shepherd dogs lived in plague-endemic regions, where marmots were infected with , whereas seronegative dogs lived in non-endemic regions. The neonatal F1 antibody titers positively correlated with the maternal titers within 3 months after birth, and the neonatal titers were similar to or slightly lower than the maternal titers.

The role of E2F1 in mediating these processes in microglia during CIRI remains unclear.
Methods: A CIRI mouse model was utilized for single-cell RNA transcriptome sequencing of brain tissues.

Surveillance for animal plague was conducted in the plague focus of the Qinghai-Tibet Plateau from 2020 to 2023. A 22.89% positive rate of serum F1 antibody was detected in live-caught marmots, alongside a 43.

However, to date, limited research utilizing Cherenkov luminescence for absolute dose calibration has been conducted owing to uncertainties arising from camera positioning and tissue surface optical properties.
Purpose: This paper introduces a novel approach to multispectral Cherenkov luminescence imaging combined with Fricke-xylenol orange gel (FXG) film, termed MCIFF, which can enable online full-field absolute dose measurement.
Pasteurella multocida is a zoonotic pathogen causing serious diseases in humans and animals. Here, we report P. multocida from wildlife on China's Qinghai-Tibet plateau with a novel capsular serotype, forming a single branch on the core-genome phylogenetic tree: four strains isolated from dead Himalayan marmot (Marmota himalayana) and one genome assembled from metagenomic sequencing of a dead Woolly hare (Lepus oiostolus).

Methods: A retrospective analysis was performed among 121 patients on the prognosis of BM of SCLC who were admitted to our hospital from 2013 to 2023. They all received first line chemotherapy.
Plague is a typical natural focus disease that circulates in different ecology of vectors and reservoir hosts. We conducted genomic population and phylogenetic analyses of the collected from the 12 natural plague foci in China with more than 20 kinds of hosts and vectors. Different ecological landscapes with specific hosts, vectors, and habitat which shape various niches for .

The activity of CCEs can be upregulated, downregulated, or modified by mutation. However, few studies have examined the role of alternative splicing in altering the properties of CCEs.

Animal husbandry is the main income for the local economy; brucellosis appears sometimes in animals and less often in humans. In this study, a retrospective investigation of plague and brucellosis seroprevalence among humans and animals was conducted to improve prevention and control measures for the two diseases.

These foci include the Rattus flavipectus plague focus of the Yunnan, Guangdong, and Fujian provinces and the Apodemus chevrieriEothenomys miletus plague focus of the highlands of northwestern Yunnan Province. The case fatality rate for plague in humans was 18.
