To further explore the impact of nutrient fortification on the ovarian secondary development of redclaw crayfish, four groups were set up: group ①, no feeding; group ②, formulated feeding; groups ③ and ④, formulated feed + nutrient bait. Results showed (1) the proportions of egg-bearing shrimp in groups ③ and ④. 2) The weight growth rate of group ① was the lowest, the maturation coefficient of unripe shrimp in group ④ was the highest, and the egg-holding rates in groups ③ and ④ were significantly higher than those of group ①.

Mandarin fish (Siniperca chuatsi) represents a typical carnivorous freshwater economic fish in China. Recently, the study of their feeding behavior to acclimate formulated diets has become a research focus. This study evaluated the effects of various diets on the body composition, nutritional content, digestive enzyme activity, gene expression, and gut microbiota of mandarin fish.

Chinese primary healthcare (PHC) sectors implement the TB Control Program (TCP) to improve active case finding, referral, treatment adherence, and health education. This study aimed to identify barriers and enablers of TCP implementation in high TB burden regions of West China.

Background: Conflicts, natural disasters, and complex emergencies present substantial health challenges to United Nations (UN) peacekeepers deployed in mission areas. This scoping review aims at summarizing previous research on the health of UN peacekeepers and identifies issues for further investigation.
Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Reviews, we systematically searched Web of Science, PubMed, EMBASE, Scopus and China National Knowledge Infrastructure (CNKI) for English and Chinese literature published from April 1997 to November 2023.
Cyclic GMP-AMP synthase (cGAS) is a key innate immune sensor that recognizes cytosolic DNA to induce immune responses against invading pathogens. The role of cGAS is conventionally recognized as a nucleotidyltransferase to catalyze the synthesis of cGAMP upon recognition of cytosolic DNA, which leads to the activation of STING and production of type I/III interferon to fight against the pathogen. However, given that hepatocytes are lack of functional STING expression, it is intriguing to define the role of cGAS in hepatocellular carcinoma (HCC), the liver parenchymal cells derived malignancy.

Samples at the egg and juvenile stages were selected. The samples at different stages were separated from the pleopods, then they were placed in incubator boxes and sterilized with different disinfectant solutions.

Acute myeloid leukemia (AML) is a deadly hematologic malignancy. In this study, miR-361-3p and BTG2 gene expression in AML blood and healthy specimens were analyzed using quantitative real-time reverse transcription polymerase chain reaction. A significant negative correlation between miR-361-3p and BTG2 was observed.

Intermuscular bones (IBs), distributed specifically in the myosepta on both sides of lower teleosts, negatively affect palatability and processing. Recent research in zebrafish and several economically important farmed fishes has led to the breakthrough discovery of the mechanism of IBs formation and generation of IBs-loss mutants. This study explored the ossification patterns of IBs in juvenile Culter alburnus.

Methods: Expression level of LINC01002, miR-650, or filamin A (FLNA) in PCa tissues and cells was assessed using quantitative real-time PCR or Western blotting. Cell proliferative and migratory capacities were investigated by Cell Counting Kit-8 (CCK-8) and wound healing assays.
As a new emerging viral pathogen, Decapod iridescent virus 1 (DIV1) seriously threatens crustacean farming in recent years. However, limited research progresses have been made on the immune mechanism between host and viral factors in response to DIV1 infection. In the current study, a natural occurrence of DIV1 infection with obvious clinical signs was found in farmed redclaw crayfish Cherax quadricarinatus, and confirmed by nested PCR detection and histopathological examination.

Previous studies found that dysbiosis has been implicated in a wide range of diseases, while the role of gastric bacteria as a biomarker for AG has not been explored.
Methods And Results: Gastric juices from cases with non-atrophic gastritis (NAG) and AG were collected for investigation of bacterial composition and function.
Background: Tuberculosis remains a major threat to global public health. Regarding its control, directly observed therapy is not suitable as a global strategy for all tuberculosis patients. Self-management may be an important patient-centered tuberculosis case management supplement to directly observed therapy.

In the present study, three members of the Fem-1 gene family (designating Fem-1A, Fem-1B, and Fem-1C, respectively) were cloned and characterized in the redclaw crayfish, Cherax quadricarinatus. Sequence analysis showed that all three Fem-1 genes contained the highly conserved ankyrin repeat motifs with variant repeat numbers, which shared similarity with other reported crustaceans.
