Temperature abuse of tuna (Thunnus alalunga) was carried out in order to assess the histamine buildup in fish-processing facilities where fish can be exposed to high temperatures for short periods of time. Histamine production was studied in tuna loins under different storage and abuse conditions. Tuna was stored at 0-2 degrees C, 3-4 degrees C, and 6-7 degrees C, and abused for 2 h daily at 20 degrees C and 30 degrees C for 7-12 days. Loins abused at 30 degrees C for 2 h daily contained potentially toxic histamine concentrations (67-382 mg kg(-1)) when stored at a low refrigeration temperature (0-2 degrees C), whereas when stored at 6-7 degrees C, the loins contained highly toxic histamine concentrations (544.5-4156.6 mg kg(-1)). Lower histamine concentrations (23-48 mg kg(-1) in loins stored at 0-2 degrees C and 124.7-2435.8 mg kg(-1) in loins stored at 6-7 degrees C) were observed in temperature-abused loins that were initially frozen. An increase over time was observed in most microbial counts tested. Bacteria isolated from the temperature-abused loins showed a varied ability of histamine production, with Morganella morganii, Klebsiella oxytoca, Staphylococcus hominis, and Enterococcus hirae being the most active histamine-producing bacteria.

Background: Access to healthcare services for women in low- and middle-income countries (LMICs) is crucial for maternal and child health and achieving the Sustainable Development Goals (SDGs). However, women in LMICs face barriers to accessing healthcare, leading to poor health outcomes. This study used Demographic and Health Survey (DHS) data from 61 LMICs between 2010-2023 to identify women's healthcare access challenges.

Purpose: Isolated coronal shear fractures of the distal humerus in adolescents are rare injuries with unique surgical challenges. Respect for the posterior blood supply, open physes, and need for direct visualization to achieve anatomic reduction are critical considerations in surgical fixation. This study presents a case series and a surgical approach used in treating these patients.

Introduction: SRS for the treatment of limited brain metastases (BM) is widely accepted, but there are still limitations in the management of numerous BM. Frameless single-isocenter multitarget SRS is a novel technique that allows for rapid treatment delivery to multiple BM. We report our preliminary clinical, dosimetric, and patient´s shifts outcomes with this technique.

Introduction: The clinical translation of chitosan-based formulations for siRNA delivery has been partially limited by their poor stability/solubility at physiological conditions, although they have good biocompatibility and cost-effectiveness.
Method: In this study, the chitosan was O-substituted with diisopropylethylamine (DIPEA) groups, which improved its solubility at pH 7.4 by increasing the degree of ionization and enhanced the ability of chitosan to load siRNA at very low amine/phosphate (N/P) ratios.

Black-bone silky fowls(Gallus gallus domesticus) have a long history of medicinal use, with the origin in Taihe county, Jiangxi province. The unclear family composition, inbreeding rate, and effective population size were inconducive to the resource conservation or breed improvement of black-bone silky fowls. A genome-wide analysis was performed to evaluate the genetic diversity of 80 black-bone silky fowls from random mating in three farms in 2021 in terms of minor allele frequency(MAF), expected heterozygosity(H_e), observed heterozygosity(H_o), effective population size(N_e), and runs of homozygosity(ROH).
