People living with HIV (PLWH) experience HIV-associated neurocognitive disorders (HAND), even though combination antiretroviral therapy (cART) suppresses HIV replication. HIV-1 transactivator of transcription (HIV-1 Tat) contributes to the development of HAND through neuroinflammatory and neurotoxic mechanisms. C-C chemokine 5 receptor (CCR5) is important in immune cell targeting and is a co-receptor for HIV viral entry into CD4+ cells.

Introduction And Objective: Observable autonomous rhythmic changes in intravesical pressure, termed bladder wall micromotion, is a phenomenon that has been linked to urinary urgency, the key symptom in overactive bladder (OAB). However, the mechanism through which micromotion drives urinary urgency is poorly understood. In addition, micromotion is inherently difficult to study in human urodynamics due to challenges distinguishing it from normal cyclic physiologic processes such as pulse rate, breathing, rectal contractions, and ureteral jetting.

Patients with heart failure with preserved ejection fraction (HFpEF) are burdened by multiple diet-sensitive comorbidities, including obesity and malnutrition. Despite this, a low percentage of patients with HFpEF have been enrolled in dietary intervention trials in heart failure and few dietary interventions have been conducted in HFpEF exclusively. This scoping review will examine available evidence regarding dietary interventions in patients with HFpEF, highlight existing gaps in knowledge, and discuss emerging dietary therapies in this population.

A new 3D metallic, ductile, and porous boron nitride as a promising anode material for sodium-ion batteries.

Phys Chem Chem Phys

January 2025

Department of Physics, Institute for Sustainable Energy and Environment, Virginia Commonwealth University, Richmond, VA, 23284, USA.

We propose a new stable three-dimensional (3D) porous and metallic boron nitride anode material, named h-BN, with good ductility for sodium-ion batteries (SIBs). Based on first-principles calculations and a tight-binding model, we demonstrate that the metallicity originates from the synergistic contribution of the p-orbital of the sp-hybridized B and N atoms, while the ductility is due to the unique configurations of B-B and N-N dimers in the structure. More importantly, this boron nitride allotrope exhibits a high reversible capacity of 582.

Traumatic brain injury (TBI) can lead to chronic neuroinflammation, and neurodegeneration associated with long-term cognitive deficits. Following TBI, the acute neuroinflammatory response involves microglial activation and the release of proinflammatory cytokines and chemokines which induce the recruitment of peripheral immune cells such as monocytes and ultimately T cells. Persistent innate and adaptive immune cell responses can lead to chronic neurodegeneration and functional deficits.
