Article Abstract
This article was designed to determine variations in phenotypic composition of fresh and frozen PBMCs for assessing utility of cryopreserved PBMCs for phenotypic assays. Relative percentages of effector memory cells increased significantly as against percentages of naïve cells which showed significant decrease after cryopreservation in HIV-uninfected samples. These differences were not significant in HIV-infected individuals. There was no significant difference in the expression of activation markers in fresh and frozen PBMCs except the HLA DR expression on CD8 cells in HIV-infected individuals, which was significantly decreased in frozen PBMCs. Thus, cryopreservation resulted in differential effect on phenotypic composition of PBMCs in HIV-infected and -uninfected individuals.

Comprehensive analysis of the systemic immune landscape across breast cancer subtypes and disease stages.

Background: Breast cancer is a systemic disease, yet the impact of tumor molecular subtype and disease stage on the systemic immune landscape remains poorly understood. In this study, we comprehensively analyzed the systemic immune landscape in a large cohort of breast cancer patients, encompassing all molecular subtypes and disease stages, alongside a control group of healthy donors.
Materials And Methods: Using multi-parameter flow cytometry, we assessed the abundance, phenotype, and activation status of diverse innate and adaptive immune cell populations across peripheral blood samples from 355 breast cancer patients and 65 healthy donors.
Disparities in Diagnostic Utilization Patterns Between Heart Failure With Preserved Ejection Fraction (HFpEF) and Heart Failure With Reduced Ejection Fraction (HFrEF): A Nationwide Analysis.

Background Heart failure (HF) is a leading cause of morbidity and hospitalization, encompassing distinct phenotypes: heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF). Disparities in diagnostic imaging may contribute to underdiagnosis and unequal care. This study evaluates differences in combined diagnostic imaging utilization between HFpEF and HFrEF, focusing on social determinants of health (SDoH) and hospital region.

Background: Ulcerative colitis (UC) is a gastrointestinal inflammatory condition with an unclear etiology. Recent findings suggest that metabolites play a pivotal role in promoting intestinal health. We have previously observed a significant enrichment in colonic branched-chain amino acids (BCAAs) in resistant mice to colitis suggesting the potential role of these metabolites in UC development.

Premise: Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood. Moricandia arvensis (Brassicaceae) exhibits seasonal floral dimorphism, with lilac spring flowers and white summer flowers.

Frailty, often linked to sarcopenia, involves reduced muscle strength and mass. While sarcopenia has multiple causes, impaired muscle protein synthesis may contribute. Leucine and resistance training (RT) are anabolic stimuli, but the long-term effects of leucine combined with RT in pre/frail older women remain unclear.
