Introduction: Several reviews have highlighted that the Patient-Generated Subjective Global Assessment (PG-SGA) is the best diagnostic tool for assessing nutritional status in cancer patients. However, previous meta-analyses summarizing the prevalence of malnutrition and overall survival in patients with gastrointestinal (GI) cancer are quite limited. This study aims to determine the overall prevalence and association between malnutrition, as defined by the PG-SGA, and mortality in adults with GI cancer.

SummaryPrevious studies have suggested that chromogranin A (CgA) is a partner molecule of secretogranin III (SgIII). In mouse pituitary corticotroph-derived AtT-20 cells, SgIII plays a role in sorting CgA/hormone aggregates into secretory granules (SGs). Although CgA expression is equivocal, CgB is clearly detectable in the rat pituitary corticotrophs.

Constitutively active mutants of BRAF cause cardio-facio-cutaneous (CFC) syndrome, characterized by growth and developmental defects, cardiac malformations, facial features, cutaneous manifestations, and mental retardation. An animal model of human CFC syndrome, the systemic BrafQ241R/+ mutant mouse, has been reported to exhibit multiple CFC syndrome-like phenotypes. In this study, we analyzed the effects of Braf mutations on neural function, separately from their effects on developmental processes.

Subnational mapping of anaemia and aetiologic factors in the West and Central African region.

Public Health Nutr

December 2024

Nutrition Section, UNICEF West and Central Africa Region, Dakar, Senegal.

Background: Inadequate water, sanitation and hygiene (WASH) in health facilities, and the low adherence to infection control protocols can increase the risk of hospital-acquired (nosocomial) infections (HAIs). The risk for HAIs can increase morbidity, and mortality, health care cost, but also contribute to increased microbial resistance.

Objectives: The study aimed to assess WASH facilities and practices, and levels of nosocomial pathogens in selected health facilities in Oromia Region and Southern, Nations and Nationalities and Peoples (SNNPs) Region.

Biomacromolecules

January 2025

Division of Molecular Science, Graduate School of Science and Technology, Gunma University, 1-5-1 Tenjin, Kiryu 376-8515, Gunma, Japan.

Article Synopsis
  • The study examined how cellulose nanofiber (CNF) enhances the fracture behavior of poly(vinyl alcohol) (PVA) hydrogels mixed with borax, particularly under freeze-thaw (FT) conditions.
  • The CNF/PVA/Borax hydrogel showed strong mechanical properties with a fracture energy of 5.8 kJ/m, and the presence of CNF was vital for preventing crack growth and maintaining energy dissipation.
  • While FT cycles improved the overall mechanical performance, they reduced the fracture energy of the hydrogels, and the material was found to be effective for cultivating stem cells, indicating its potential as a scaffold for tissue engineering.

We prepared biocompatible elastic fibers with high porosity and high tensile strength from poly[()-3-hydroxybutyrate--4-hydroxybutyrate], which is a microbial polyester that can be produced from renewable carbon resources by isothermal crystallization. It was possible to control the pore size by adjusting the isothermal crystallization time. Most of the pores were approximately less than 10 μm in diameter, did not penetrate, and were distributed discontinuously throughout the fibers.

Electronic address:

Temperature abuse occurs frequently during transportation and frozen storage, which affects the quality of frozen aquatic products. Recrystallization generated by temperature abuse leads to irreversible damage to the muscle tissue and microstructure, and exacerbates undesirable oxidation reactions, thus reducing the quality of frozen aquatic products. In this study, a modeling system of temperature abuse alternating between -24 °C and -7 °C was established to evaluate the effect of temperature abuse on the stability of frozen large yellow croaker.
