Excited-State Carrier Dynamics in Semiconducting Heterostructures from Self-Sorted NIR Active Dyes.

Heterostructures comprise two or more different semiconducting materials stacked either as co-assemblies or self-sorted based on their dynamics of aggregates. However, self-sorting in heterostructures is rather significant in improving the short exciton diffusion length and charge separation. Despite small organic molecules being known for their self-sorting nature, macrocyclic are hitherto unknown owing to unrestrained assemblies from extended π-conjugated systems.

Bariatric surgery and HIV: Joint venture between family, primary care, and HIV physicians.

We report a case of a 49-year-old female with a history of HIV infection for 12 years. The patient had excellent compliance with antiretroviral medications, raltegravir 400 mg twice daily and truvada once daily for HIV. Over the years, she maintained an undetectable viral load with a CD4+ count >200 cells/μL.

Extraction and incorporation of cellulose microfibers from textile wastes into MXene-enhanced PVA-borax hydrogel for multifunctional wearable sensors.

Conductive hydrogel has drawn great concern in wearable sensors, human-machine interfaces, artificial intelligence (AI), health monitoring, et al. But it still remains challenge to develop hydrogel through facile and sustainable methods. In this work, a conductive, flexible, bendable, and self-healing hydrogel (PBCM) composed of polyvinyl alcohol (PVA), borax, cellulose microfibers (CMFs), and MXene nanosheet was fabricated by a simple and efficient strategy.

Plasma biomarkers of neurodegeneration in the brain (UCH‐L1 and NfL) become exponentially higher with age from early childhood, and treatment of Alzheimer’s disease participants with granulocyte‐macrophage colony‐stimulating factor (GM‐CSF) lowers age‐associated levels of plasma UCH‐L1 by six decades.

Background: Increasing age is the greatest risk factor for age‐associated cognitive decline (AACD) and, especially in females, for developing Alzheimer’s disease (AD). Mechanisms underlying this connection are unknown, but neuronal loss and brain atrophy accompany aging and AD and likely contribute to cognitive deficits. There are currently no means to measure neuronal cell death during life and no means to prevent it.
