[Association between alterations in the expanded lymphoid profileby flow cytometry and inborn errors of immunity].

Objective: To evaluate the association between the expanded lymphoid profile and inborn errors of immunity using flow cytometry.

Methods: Observational and cross-sectional, case-control study, carried out in patients with a diagnosis or clinical suspicion of inborn errors of immunity, treated at the Santísima Trinidad Children's Hospital in Córdoba, Argentina, from August 2021 to November 2022. Clinical data were collected, and peripheral blood samples were obtained for flow cytometry analysis, using the PIDOT tube, to identify lymphocyte subpopulations.

Impact of Nonalcoholic Fatty Liver Disease on the Survival of People Living With HIV.

Background: Nonalcoholic fatty liver disease (NAFLD) is an increasing concern for people living with HIV (PLWH). However, information on the impact of NAFLD on the prognosis of PLWH is very scarce.

Aims: To investigate the influence of NAFLD on the overall and liver-related mortality in PLWH.

Improving mortar properties using traditional ceramic materials ground to precisely controlled sizes.

The present work investigates the impact of particle size reduction of traditional ceramic materials as partial substitutes for Portland cement in mortars. Ceramic brick, ceramic tile, and stoneware were selected, with three particle sizes ( of 1, 5, and 15 μm) achieved through grinding operations adapted to each material grindability. The reactivity of ceramic powders was assessed via dissolution in saturated lime solution.

New Eco-Cements Made with Marabou Weed Biomass Ash.

Biomass ash is currently attracting the attention of science and industry as an inexhaustible eco-friendly alternative to pozzolans traditionally used in commercial cement manufacture (fly ash, silica fume, natural/calcined pozzolan). This paper explores a new line of research into Marabou weed ash (MA), an alternative to better-known conventional agro-industry waste materials (rice husk, bagasse cane, bamboo, forest waste, etc.) produced in Cuba from an invasive plant harvested as biomass for bioenergy production.
