Aim: To explore the effects of different temperature and time on preservation damages in liquid blood.
Methods: Take blood sample from 10 healthy blood donors, put the fresh blood into CP2D-A liquid at 0 degrees C and 4 degrees C, and take the samples after 1 week, 2 weeks and 3 weeks, and then measured the contents of GSH-Px, TSH, LPO, the contracting protein of RBC, and membrane fluidity.
Results: At the same temperature, when the preservation time is prolonged, peroxidation is increased, the preservation damages are also augmented; the damages are declined when the temperature is lower during the same period, the aging of blood was more evident at 4 degrees C.
Conclusion: Blood peroxidation temperature is lower. The 0 degrees C group is better than 4 degrees C group.

Implementation of Time-Averaged Restraints with UNRES Coarse-Grained Model of Polypeptide Chains.
J Chem Theory Comput

Time-averaged restraints from nuclear magnetic resonance (NMR) measurements have been implemented in the UNRES coarse-grained model of polypeptide chains in order to develop a tool for data-assisted modeling of the conformational ensembles of multistate proteins, intrinsically disordered proteins (IDPs) and proteins with intrinsically disordered regions (IDRs), many of which are essential in cell biology. A numerically stable variant of molecular dynamics with time-averaged restraints has been introduced, in which the total energy is conserved in sections of a trajectory in microcanonical runs, the bath temperature is maintained in canonical runs, and the time-average-restraint-force components are scaled up with the length of the memory window so that the restraints affect the simulated structures. The new approach restores the conformational ensembles used to generate ensemble-averaged distances, as demonstrated with synthetic restraints.

Background: Aflatoxin M1 (AFM1) is a derivative of aflatoxin B1 and a significant contaminant of milk and dairy products. In this study, we implemented an umbrella review of all existing systematic reviews and meta-analyzing studies to apprise and summarize the worldwide prevalence and level of AFM1 in milk and dairy products.
Methods: We conducted a systematic review of structured review and meta-analysis articles published in English until January 2024, with no time limit.
Correlation between night sweats and season fluctuation in China.
Front Public Health
January 2025
Shandong Academy of Chinese Medicine, Jinan, China.
Background: Night sweats are a condition in which an individual sweats excessively during sleep without awareness, and stops when they wake up. Prolonged episodes of night sweats might result in the depletion of trace elements and nutrients, affecting the growth and development of children.
Purpose: To investigate the relationship between sweat nights and season.
A comparative evaluation of haematological and biochemical parameters of and species living in Gökova Bay, Türkiye.

Faculty of Fisheries, Muğla Sıtkı Koçman University, Muğla, Türkiye.
This study aims to determine and compare the reference values of the haematological and biochemical blood parameters of two fish species collected from the Gökova Bay (Muğla, South-Western of Türkiye): the non-native and invasive Randall's threadfin bream, and the native Common pandora, . Both species inhabit the same environment and compete for resources. Blood samples were collected from a total of 100 fish samples (50 and 50 ) which were caught from a depth of 30 to 60 meters between February 2023 and July 2024.

Plant infiltration techniques, particularly agroinfiltration, have transformed plant science and biotechnology by enabling transient gene expression for genetic engineering of plants or genomic studies. Recently, the use of infiltration has expanded to introduce nanomaterials and polymers in plants to enable nonnative functionalities. Despite its wide use, the impact of the infiltration process on plant physiology needs to be better understood.
