Laboratory of Brain and Cognition (LBC), National Institute of Mental Health (NIMH), National Institutes of Health (NIH), Bethesda, Maryland (MD), USA.

Damage to the primary visual pathway can cause vision loss. Some cerebrally blind people retain degraded vision or sensations and can perform visually guided behaviors. These cases motivate investigation and debate on blind field conscious awareness and linked residual neural processing.

Unstable States and the Biologization of Mental Illness.

SSM Ment Health

December 2024

Georgetown University, Department of Psychology, 306C White-Gravenor Hall, 3700 O St. NW, Washington, DC 20057.

We critically examine how biological narratives of mental illness mediate relations between personal experiences and socio-structural conditions of distress in crisis contexts. Using three case studies of contemporary crises in Russia, the Republic of Cameroon, and Bangladesh, we showcase the ways in which biological meanings of mental illness carry political and structural significance as authorities employ "biologization" for political ends. In Russia, biologization is strategically useful to authorities seeking to control a populace, as chronic "conditions" can be "treated" indefinitely.

Background: Patients with cancer frequently encounter complex treatment pathways, often characterized by challenges with coordinating and scheduling appointments at various specialty services and locations. Identifying patients who might benefit from scheduling and social support from community health workers or patient navigators is largely determined on a case-by-case basis and is resource intensive.

Objective: This study aims to propose a novel algorithm to use scheduling data to identify complex scheduling patterns among patients with transportation and housing needs.

Precisely crafted hierarchical architectures found in naturally derived biomaterials underpin the exceptional performance and functionality showcased by the host organism. In particular, layered helical assemblies composed of cellulose, chitin, or collagen serve as the foundation for some of the most mechanically robust and visually striking natural materials. By utilizing structured materials in additive manufacturing techniques such as extrusion-based 3D printing, the intrinsic deformation process can be used to implement bottom-up design of printed constructs, offering the potential to create intricate macroscale geometries with embedded nanoscale functionality.

Background: Pancreatic ductal adenocarcinoma (PDAC) is mostly refractory to immunotherapy due to immunosuppression in the tumor microenvironment and cancer cell-intrinsic T cell tolerance mechanisms. PDAC is described as a "cold" tumor type with poor infiltration by T cells and factors leading to intratumoral T cell suppression have thus received less attention. Here, we identify a cancer cell-intrinsic mechanism that contributes to a T cell-resistant phenotype and describes potential combinatorial therapy.

Institute of Hypertension, Zhongshan School of Medicine, Sun Yat-sen University, Guangzhou, China; Department of Pathophysiology, Zhongshan School of Medicine, Sun Yat-sen University, Guangzhou, China. Electronic address:

Epithelial sodium channel (ENaC), located in the collecting duct principal cells of the kidney, is responsible for the reabsorption of sodium and plays a critical role in the regulation of extracellular fluid volume and consequently blood pressure. The G protein-coupled bile acid receptor (TGR5) is a membrane receptor mediating effects of bile acid and is implicated in kidney diseases. The current study aims to investigate whether TGR5 activation in the kidney regulated ENaC expression and potential mechanism.

January 2025

Dr. Phillip Frost Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, Miami, FL.

Frontal Fibrosing Alopecia (FFA) is a primary lymphocytic cicatricial alopecia predominantly affecting postmenopausal Caucasian women. It is characterized by a progressive frontotemporal hairline recession that presents as a scarring hairless band and is often accompanied by eyebrow and body hair loss. Although initially described in postmenopausal women, FFA has been observed in a broader demographic, including premenopausal women and occasionally men.

Background: Black women living with HIV (WLHIV) often have suboptimal ART adherence due to a multitude of social and structural barriers, including HIV-related stigma. Trust in healthcare providers plays a significant role in adhering to ART and is likely lower among Black WLHIV compared to their White counterparts. This study examined the relationship between experienced stigma in healthcare settings and ART adherence and viral suppression through anticipated stigma in healthcare settings, internalized stigma, and medical mistrust.

Food insecurity (FI), the lack of access to adequate food, is linked with negative health and psychological outcomes. FI is typically measured retrospectively over the last year; although this measurement is useful to understand FI prevalence to inform broad policy, it leaves the experience of FI in everyday life poorly understood. Understanding how FI varies across shorter periods of time (days or weeks) can help inform FI prevention and/or intervention.

Artificial intelligence (AI) scribe applications in the healthcare community are in the early adoption phase and offer unprecedented efficiency for medical documentation. They typically use an application programming interface with a large language model (LLM), for example, generative pretrained transformer 4. They use automatic speech recognition on the physician-patient interaction, generating a full medical note for the encounter, together with a draft follow-up e-mail for the patient and, often, recommendations, all within seconds or minutes.

The role of dynamic shape cues in the recognition of emotion from naturalistic body motion.

Atten Percept Psychophys

January 2025

Department of Psychology, Rutgers University - New Brunswick, 152 Frelinghuysen Rd, Piscataway, NJ, 08854, USA.

Human observers can often judge emotional or affective states from bodily motion, even in the absence of facial information, but the mechanisms underlying this inference are not completely understood. Important clues come from the literature on "biological motion" using point-light displays (PLDs), which convey human action, and possibly emotion, apparently on the basis of body movements alone. However, most studies have used simplified and often exaggerated displays chosen to convey emotions as clearly as possible.
