"The Brain is…": A Survey of the Brain's Many Definitions.

A reader of the peer-reviewed neuroscience literature will often encounter expressions like the following: 'the brain is a dynamic system', 'the brain is a complex network', or 'the brain is a highly metabolic organ'. These expressions attempt to define the essential functions and properties of the mammalian or human brain in a simple phrase or sentence, sometimes using metaphors or analogies. We sought to survey the most common phrases of the form 'the brain is…' in the biomedical literature to provide insights into current conceptualizations of the brain.

Assessing the Risk of Sexually Transmitted Infections among Men who have Sex with Men in San Francisco during COVID-19: A Socio-ecological Analysis.

Background: Men who have sex with men (MSM) are disproportionately affected by sexually transmitted infections, a disparity that has only worsened in recent years. During the COVID-19 pandemic, an overall increasing trend remained.

Methods: We utilized data from the MSM cycle of the National HIV Behavioral Surveillance (NHBS) study in San Francisco, California, conducted from June 2021 through December 2021, to identify socio-ecological disruptions during the COVID-19 pandemic that were associated with sexually transmitted infections.

Sensitive Fluorescent Probe for Al, Cr and Fe: Application in Real Water Samples and Logic Gate.

Construction of single probes for simultaneous detection of common trivalent metal ions has attracted much attention due to higher efficiency in analysis and cost. A naphthalimide-based fluorescent probe K1 was synthesized for selective detection of Al, Cr and Fe ions. Fluorescence emission intensity at 534 nm of probe K1 in DMSO/HO (9:1, v/v) was significantly enhanced upon addition of Al, Cr and Fe ions while addition of other metal ions (Li, Na, K, Ag, Cu, Fe, Zn, Co, Ni, Mn, Sr, Hg, Ca, Mg, Ce, Bi and Au) did not bring about substantial change in fluorescence emission.

Early childhood stress and amygdala structure in children and adolescents with neurodevelopmental disorders.

Children and adolescents with neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) may be more susceptible to early life stress compared to their neurotypical peers. This increased susceptibility may be linked to regionally-specific changes in the striatum and amygdala, brain regions sensitive to stress and critical for shaping maladaptive behavioural responses. This study examined early life stress and its impact on striatal and amygdala development in 62 children and adolescents (35 males, mean age = 10.

The cold tolerance of the terrestrial slug, Ambigolimax valentianus.

Terrestrial molluscs living in temperate and polar environments must contend with cold winter temperatures. However, the physiological mechanisms underlying the survival of terrestrial molluscs in cold environments and the strategies employed by them are poorly understood. Here we investigated the cold tolerance of Ambigolimax valentianus, an invasive, terrestrial slug that has established populations in Japan, Canada, and Europe.

The role of signaling systems of plant in responding to key astrophysical factors: increased ionizing radiation, near-null magnetic field and microgravity.

Plants will form the basis of artificial ecosystems in space exploration and the creation of bases on other planets. Astrophysical factors, such as ionizing radiation (IR), magnetic fields (MF) and gravity, can significantly affect the growth and development of plants beyond Earth. However, to date, the ways in which these factors influence plants remain largely unexplored.

Molecular Stratification of Light-Chain Cardiac Amyloidosis With F-Florbetapir and Ga-FAPI-04 for Enhanced Prognostic Precision.

Background: Cardiac involvement in amyloid light chain (AL) amyloidosis significantly influences prognosis, necessitating timely diagnosis and meticulous risk stratification.

Objectives: This prospective study aimed to delineate the molecular phenotypes of AL cardiac amyloidosis (AL-CA) by characterizing fibro-amyloid deposition using F-florbetapir and gallium-68-labeled fibroblast activation protein inhibitor-04 (Ga-FAPI-04) positron emission tomography (PET)/computed tomography (CT) imaging. The authors also proposed a novel molecular stratification methodology for prognosis.

A Primer on Carceral Health for Clinicians: Care Delivery, Regulatory Oversight, Legal and Ethical Considerations, and Clinician Responsibilities.

The United States has one of the highest incarceration rates in the world, with approximately 1.7 million individuals detained in jails or federal or state prisons. Chronic medical conditions are more prevalent among adults in custody than among their nonincarcerated counterparts, resulting in needs that often surpass the on-site medical treatment capabilities of carceral facilities.

LINE1 elements at distal junctions of rDNA repeats regulate nucleolar organization in human embryonic stem cells.

The nucleolus is a major subnuclear compartment where ribosomal DNA (rDNA) is transcribed and ribosomes are assembled. In addition, recent studies have shown that the nucleolus is a dynamic organizer of chromatin architecture that modulates developmental gene expression. rDNA gene units are assembled into arrays located in the p-arms of five human acrocentric chromosomes.

CASE (CemiplimAb-rwlc Survivorship and Epidemiology): a study in advanced basal cell carcinoma.

Patients diagnosed with metastatic basal cell carcinoma (BCC) have a poor prognosis. The current standard of care for adults with locally advanced or metastatic BCC who are not candidates for surgery or radiation therapy is treatment with hedgehog pathway inhibitors (HHIs). For patients who progress while on this therapy, further treatment options are limited.

FT538, iPSC-derived NK cells, enhance AML cell killing when combined with chemotherapy.

Induced pluripotent stem cell (iPSC)-derived natural killer (NK) cells offer an opportunity for a standardized, off-the-shelf treatment with the potential to treat a wider population of acute myeloid leukaemia (AML) patients than the current standard of care. FT538 iPSC-NKs express a high-affinity, noncleavable CD16 to maximize antibody dependent cellular cytotoxicity, a CD38 knockout to improve metabolic fitness, and an IL-15/IL-15 receptor fusion preventing the need for cytokine administration, the main source of adverse effects in NK cell-based therapies. Here, we sought to evaluate the potential of FT538 iPSC-NKs as a therapy for AML through their effect on AML cell lines and primary AML cells.

"Listening to understand," exploring postpartum women's perceptions of their social networks and social support in relation to their health behaviors and weight: A qualitative exploratory study.

Background: Postpartum is a critical period to interrupt weight gain across the lifespan, decrease weight-related risk in future pregnancies, promote healthy behaviors that are often adopted during pregnancy, and improve long-term health. Because the postpartum period is marked by unique challenges to a person's ability to prioritize healthy behaviors, a multi-level/domain approach to intervention beyond the individual-level factors of diet and activity is needed.

Objectives: The purpose of this study was to understand postpartum people's perceptions about the relationship between their social networks and support, and their health behaviors and weight.
