Purpose: This study aims to explore parameters of nutritional assessment and food intake as predictors of clinical outcomes after hematopoietic stem cell transplant (HSCT).
Methods: The study was conducted retrospectively with 56 adult patients undergoing allogeneic HSCT. Energy and protein daily intake were used to calculate the energy and protein cumulative deficit. The nutritional assessment tools were weight, body mass index (BMI), triceps skinfold (TSF), and arm muscle area (AMA) before HSCT and after HSCT.
Results: Food intake decreased immediately after the transplant and the energy and protein cumulative deficit increased during hospitalization (p < 0.01). Almost 70 % of patients had severe weight loss (greater than 5 %), and the average percentage of weight loss was 8.5 ± 3.9 %. BMI and weight loss percentage were not correlated with the presence of acute graft versus host disease (GVHD) and mortality within 180 days in this population. On the other hand, correlation was found between the initial (pre-HSCT) AMA equal to or below the 15th percentile, with the presence of acute GVHD (p = 0.024), and mortality within 180 days after HSCT (p = 0.010).
Conclusions: The AMA measured pre-HSCT showed to be a potential predictor of acute GVHD and mortality up to 180 days after transplant in adult patients.

Epstein-Barr virus-driven cardiolipin synthesis sustains metabolic remodeling during B cell transformation.

The Epstein-Barr virus (EBV) infects nearly 90% of adults globally and is linked to over 200,000 annual cancer cases. Immunocompromised individuals from conditions such as primary immune disorders, HIV, or posttransplant immunosuppressive therapies are particularly vulnerable because of EBV's transformative capability. EBV remodels B cell metabolism to support energy, biosynthetic precursors, and redox equivalents necessary for transformation.

Article Synopsis
- Parasitoid wasps, a highly diverse group of animals, use their venoms to manipulate the physiology of host larvae for their benefit.
- Researchers discovered that a specific wasp can cause the death and dysfunction of its host's tissue precursors, a process called imaginal disc degradation (IDD).
- The study identified two venom proteins crucial for IDD, showing how the wasp's venom strategically ensures the host grows but inhibits its transformation into adulthood.
The chloroplast RNA-binding protein CP29A supports expression during cold acclimation.

The chloroplast genome encodes key components of the photosynthetic light reaction machinery as well as the large subunit of the enzyme central for carbon fixation, Ribulose-1,5-bisphosphat-carboxylase/-oxygenase (RuBisCo). Its expression is predominantly regulated posttranscriptionally, with nuclear-encoded RNA-binding proteins (RBPs) playing a key role. Mutants of chloroplast gene expression factors often exhibit impaired chloroplast biogenesis, especially in cold conditions.

Solvent environment may significantly affect the equilibria involving flexible solute species, such as proteins and polymers. In the present work, a computation scheme is formulated for the change in the excess chemical potential of a flexible solute molecule upon variation of the solvent condition. The formulation adopts the scheme of error minimization in parallel to the method of Bennett acceptance ratio, and an exact expression is presented that provides the change in the excess chemical potential from solvation free energies computed in two solvent conditions of interest.

The daily light-dark cycle is a recurrent and predictable environmental phenomenon to which many organisms, including cyanobacteria, have evolved to adapt. Understanding how cyanobacteria alter their metabolic attributes in response to subjective light or dark growth may provide key features for developing strains with improved photosynthetic efficiency and applications in enhanced carbon sequestration and renewable energy. Here, we undertook a label-free proteomic approach to investigate the effect of extended light (LL) or extended dark (DD) conditions on the unicellular cyanobacterium ATCC 51142.
