Glaucoma is characterized by a progressive loss of retinal ganglion cells (RGCs), leading to irreversible visual function impairment. Sustained increase in intraocular pressure represents a major risk factor for glaucoma, yet the underlying mechanisms of RGC apoptosis induced by intraocular pressure remains unclear. This study aims to investigate the role of TRPV4 in RGC apoptosis in a rat model of chronic ocular hypertension (COH) and the underlying molecular mechanism. In the COH rat models, we evaluated the visual function, retinal pathological changes and RGC apoptosis...

PURPOSE OF REVIEW: The purpose of this article is to review recent advances in the role of natural killer (NK) cells in approaches aimed at reducing the latent HIV-1 reservoir. RECENT FINDINGS: Multiple approaches to eliminate cells harboring latent HIV-1 are being explored, but have been met with limited success so far. Recent studies have highlighted the role of NK cells and their potential in HIV-1 cure efforts. Anti-HIV-1 NK cell function can be optimized by enhancing NK cell activation, antibody dependent cellular cytotoxicity, reversing inhibition of NK cells as well as by employing immunotherapeutic complexes to enable HIV-1 specificity of NK cells...

PURPOSE OF THE REVIEW: The central nervous system (CNS) is an hotspot for HIV persistence and may be a major obstacle to overcome for curative strategies. The peculiar anatomical, tissular and cellular characteristics of the HIV reservoir in the CNS may need to be specifically addressed to achieve a long-term HIV control without ART. In this review, we will discuss the critical challenges that currently explored curative strategies may face in crossing the blood-brain barrier (BBB), targeting latent HIV in brain-resident myeloid reservoirs, and eliminating the virus without eliciting dangerous neurological adverse events...

PURPOSE OF REVIEW: Currently, HIV-infected patients are treated with antiretroviral therapy. However, when the treatment is interrupted, viral rebound occurs from latently infected cells. Therefore, scientists aim to develop an HIV-1 cure which eradicates or permanently silences the latent reservoir. RECENT FINDINGS: Previously, scientists focused on the shock-and-kill cure strategy, which aims to eradicate the latent reservoir using latency-reactivating agents...

PURPOSE OF REVIEW: Elite controllers (ECs) and Posttreatment controllers (PTCs) represent a small subset of individuals who are capable of maintaining drug-free control of HIV plasma viral loads despite the persistence of a replication-competent viral reservoir. This review aims to curate recent experimental studies evaluating viral reservoirs that distinguish EC/PTC and may contribute to their ability to maintain undetectable viral loads in the absence of antiretroviral therapy. RECENT FINDINGS: Recent studies on ECs have demonstrated that integration sites of intact proviruses in EC/PTC are markedly biased towards heterochromatin regions; in contrast, intact proviruses in accessible and permissive chromatin were profoundly underrepresented...

IMPORTANCE: The diagnosis of unexplained infertility presents a dilemma as it signifies both uncertainty about the cause of infertility and the potential for natural conception. Immediate treatment of all would result in overtreatment. Prediction models estimating the likelihood of natural conception and subsequent live birth can guide treatment decisions. OBJECTIVE: To evaluate if in couples with unexplained infertility, prediction models are effective in guiding treatment decisions...

Carbon-based supercapacitors have shown great promise for miniaturized electronics and electric vehicles, but are usually limited by their low volumetric performance, which is largely due to the inefficient utilization of carbon pores in charge storage. Herein, we develop a reliable and scalable boric acid templating technique to prepare boron and oxygen co-modified highly-dense yet ultramicroporous carbons (BUMCs). The carbons are featured with high density (up to 1.62 g cm-3 ), large specific surface area (up to 1050 m2 g-1 ), narrow pore distribution (0...

BACKGROUND: Social robots are becoming increasingly important as companions in our daily lives. Consequently, humans expect to interact with them using the same mental models applied to human-human interactions, including the use of cospeech gestures. Research efforts have been devoted to understanding users' needs and developing robot's behavioral models that can perceive the user state and properly plan a reaction. Despite the efforts made, some challenges regarding the effect of robot embodiment and behavior in the perception of emotions remain open...

The pressure dependent reaction mechanism of CO2 hydrogenation over In2 O3 was investigated. CO2 hydrogenation on In2 O3 can produce methanol only at high pressure, while the atmospheric pressure operation leads to the formation of CO. The conversion from HCOO* to H3 CO* is accelerated at high pressure, leading to the formation of methanol with the formate route (CO2 * → HCOO* → H3 CO* → H3 COH).

PURPOSE OF REVIEW: Expression of noncoding RNAs (ncRNAs) is more tissue and cell type-specific than expression of protein-coding genes. Understanding the mechanisms of action of ncRNAs and their roles in HIV replication and latency may inform targets for the latent HIV reservoir reactivation or elimination with high specificity to CD4+ T cells latently infected with HIV. RECENT FINDINGS: While the number of studies in the field of ncRNAs and HIV is limited, evidence points to complex interactions between different ncRNAs, protein-coding RNAs, and proteins...
