The PRO-AGE Tool and Its Association With Post Discharge Outcomes in Older Adults Admitted From the Emergency Department.

Background: Existing risk scores assessing geriatric vulnerability in the emergency department (ED) have shown limited predictive power, especially in diverse populations. We investigated the relationship of a quick and easy-to-administer geriatric vulnerability scoring system with functional decline and mortality in older patients admitted to multiple hospitals through the ED in the United States (US) and Brazil (BR).

Method: Federated, international, multicenter observational study of hospitalized ED patients aged ≥ 65 from US and BR.

High-affinity promotor binding of YhaJ mediates a low signal leakage for effective DNT detection.

The YhaJ transcription factor responds to dinitrophenol (DNT) and its metabolic products. The YhaJ-involving cells have been exploited for whole-cell biosensors of soil-buried landmines. Such biosensors would decrease the damage to personnel who approach landmine fields.

Effect of polystyrene micro/nanoplastics on PCBs removal in constructed wetlands planted with Myriophyllum aquaticum.

The co-occurrence of microplastics (MPs) and nanoplastics (NPs) with polychlorinated biphenyls (PCBs) is an emerging environmental concern. Wetland plants, with their unique anaerobic-aerobic environments, offer a promising approach for PCB removal. However, the impact of MPs and NPs on PCBs dynamics in constructed wetlands is not well understood.

Mammalian nucleophagy: process and function.

The nucleus is a highly specialized organelle that houses the cell's genetic material and regulates key cellular activities, including growth, metabolism, protein synthesis, and cell division. Its structure and function are tightly regulated by multiple mechanisms to ensure cellular integrity and genomic stability. Increasing evidence suggests that nucleophagy, a selective form of autophagy that targets nuclear components, plays a critical role in preserving nuclear integrity by clearing dysfunctional nuclear materials such as nuclear proteins (lamins, SIRT1, and histones), DNA-protein crosslinks, micronuclei, and chromatin fragments.

Recent Advances of Macrostructural Porous Silicon for Biomedical Applications.

Porous silicon (pSi) has gained substantial attention as a versatile material for various biomedical applications due to its unique structural and functional properties. Initially used as a semiconductor material, pSi has transitioned into a bioactive platform, enabling its use in drug delivery systems, biosensing, tissue engineering scaffolds, and implantable devices. This review explores recent advancements in macrostructural pSi, emphasizing its biocompatibility, biodegradability, high surface area, and tunable properties.
