CT-Based Body Composition and Frailty as Predictors of Survival Among Older Adults With Gastrointestinal Malignancies.

Background: Older adults with cancer are at an increased risk of treatment related toxicities and early death. Routinely collected clinico-demographic characteristics inadequately explain this increased risk limiting accurate prognostication. Prior studies have suggested that altered body composition and frailty are independently associated with worse survival among older adults with cancer; however, their combined influence remains unclear.

Optimization of the large-scale production for Erwinia amylovora bacteriophages.

Background: Fire blight, caused by Erwinia amylovora, poses a significant threat to global agriculture, with antibiotic-resistant strains necessitating alternative solutions such as phage therapy. Scaling phage therapy to an industrial level requires efficient mass-production methods, particularly in optimizing the seed culture process. In this study, we investigated large-scale E.

Thymol as Biofilm and Efflux Pump Inhibitor: A Dual-Action Approach to Combat Mycobacterium tuberculosis.

Tuberculosis (TB) remains a significant global health challenge, exacerbated by the emergence of drug-resistant strains of Mycobacterium tuberculosis (M. tb). The complex biology of M.

Nature of local disorder in β-NaYF-based, near-infrared upconverting core nanocrystals due to deliberate incorporation of a symmetry perturbing agent.

As nanocrystalline materials exhibit complex disorders, assessment of the local disorder at the nanoscale induced by implanted lattice defects plays a crucial role in understanding the structure-function relationship in these materials. In this report, a comprehensive structural analysis was performed on upconverting nanocrystals (UCNCs) of NaYF/Nd/Yb/Tm, containing varying concentrations of Li to induce deliberate lattice defects. Subsequently, a comprehensive structural analysis of the UCNCs was performed using synchrotron radiation-based high-resolution X-ray diffraction (HRXRD), high-energy total angle scattering coupled with pair distribution function (PDF) analysis, neutron diffraction (ND) and EXAFS probing.
