Cortex-wide characterization of decision-making neural dynamics during spatial navigation.

Decision-making during freely moving behaviors involves complex interactions among many cortical and subcortical regions. However, the spatiotemporal coordination across regions to generate a decision is less understood. Using a head-mounted widefield microscope, cortex-wide calcium dynamics were recorded in mice expressing GCaMP7f as they navigated an 8-maze using two paradigms.

Elucidation of the genetic architecture of water absorption capacity in hard winter wheat through genome wide association study.

Water absorption capacity (WAC) influences various aspects of bread making, such as loaf volume, bread yield, and shelf life. Despite its importance in the baking process and end-product quality, its genetic determinants are less explored. To address this limitation, a genome-wide association study was conducted on 337 hard wheat (Triticum aestivum L.

Addressing Racial Disparities in the Hypertensive Disorders in Pregnancy: A Plan for Action from the Preeclampsia Foundation's Racial Disparities Task Force.

Hypertensive disorders of pregnancy (HDP) are among the leading causes of maternal mortality in the United States, with Black women and birthing people disproportionately having higher HDP-related deaths and morbidity. In 2020, the Preeclampsia Foundation formed a national Racial Disparities Task Force (RDTF) to identify key recommendations to address issues of racial disparities related to HDP. Recommendations are centered around the Foundation's three pillars: Community, Healthcare Practice, and Research.

Highly restrictive and directional penetration of the blood cerebral spinal fluid barrier by JCPyV.

The human polyomavirus JCPyV is an opportunistic pathogen that infects greater than 60% of the world's population. The virus establishes a persistent and asymptomatic infection in the urogenital system but can cause a fatal demyelinating disease in immunosuppressed or immunomodulated patients following invasion of the CNS. The mechanisms responsible for JCPyV invasion into CNS tissues are not known but direct invasion from the blood to the cerebral spinal fluid via the choroid plexus has been hypothesized.

Comparative analysis of PD-L1 expression and tumor-infiltrating lymphocytes in metaplastic breast carcinoma and gynecologic carcinosarcoma: A single-institution retrospective study.

Metaplastic breast carcinoma (MBC) and gynecologic carcinosarcoma (GCS) are rare, clinically aggressive cancers that demonstrate epithelial components and mesenchymal or sarcomatoid components. In this study, we assessed PD-L1 expression and tumor-infiltrating lymphocytes (TILs) in MBC and GCS. Overall, PD-L1 positivity using the SP142 clone was seen in 50 % of MBC and 51.

Viscoelastic testing guided coagulation management in factor VII deficiency for spinal anaesthesia and caesarean section.

The risks and benefits of spinal anaesthesia must be assessed in patients with coagulation disorders. A woman in her 20s with congenital factor VII (FVII) deficiency (31%) was admitted at 38 weeks for caesarean delivery. A rotational thromboelastometry (ROTEM) analysis showed normal coagulation and spinal anaesthesia was performed safely.

JCPyV infection of primary choroid plexus epithelial cells reduces expression of critical junctional proteins and increases expression of barrier disrupting inflammatory cytokines.

Unlabelled: The human polyomavirus, JCPyV, establishes a lifelong persistent infection in the peripheral organs of a majority of the human population worldwide. Patients who are immunocompromised due to underlying infections, cancer, or to immunomodulatory treatments for autoimmune disease are at risk for developing progressive multifocal leukoencephalopathy (PML) when the virus invades the CNS and infects macroglial cells in the brain parenchyma. It is not yet known how the virus enters the CNS to cause disease.

Diabetic Peripheral Neuropathy: Prevention and Treatment.

Diabetic peripheral neuropathy occurs in up to 50% of patients with diabetes mellitus and increases the risk of diabetic foot ulcers and infections. Consistent screening and clear communication are essential to decrease disparities in assessment of neuropathic symptoms and diagnosis. Physicians should address underlying risk factors such as poor glycemic control, vitamin B12 deficiency, elevated blood pressure, and obesity to reduce the likelihood of developing neuropathy.

Identifying novel sources of resistance to wheat stem sawfly in five wild wheat species.

Background: The wheat stem sawfly (WSS, Cephus cinctus) is a major pest of wheat (Triticum aestivum) and can cause significant yield losses. WSS damage results from stem boring and/or cutting, leading to the lodging of wheat plants. Although solid-stem wheat genotypes can effectively reduce larval survival, they may have lower yields than hollow-stem genotypes and show inconsistent solidness expression.

A Novel Case-Based Learning Activity With a Focus on Food Insecurity.

Objective: Food insecurity is a social determinant of health (SDOH) affecting 1 in 10 households per year in the United States and has major impacts on the course of chronic health conditions. It is beneficial to introduce screening and appropriate treatment plans to medical students. This study utilized a novel case-based learning exercise (CBLE) to assess confidence, attitudes and improvements in knowledge on recognizing and addressing food insecurity.

Discovery of Charge Order in the Transition Metal Dichalcogenide Fe_{x}NbS_{2}.

The Fe intercalated transition metal dichalcogenide (TMD), Fe_{1/3}NbS_{2}, exhibits remarkable resistance switching properties and highly tunable spin ordering phases due to magnetic defects. We conduct synchrotron x-ray scattering measurements on both underintercalated (x=0.32) and overintercalated (x=0.

HaploCatcher: An R package for prediction of haplotypes.

Wheat (Triticum aestivum L.) is crucial to global food security but is often threatened by diseases, pests, and environmental stresses. Wheat-stem sawfly (Cephus cinctus Norton) poses a major threat to food security in the United States, and solid-stem varieties, which carry the stem-solidness locus (Sst1), are the main source of genetic resistance against sawfly.

Taxonomic distribution of metabolic functions in bacteria associated with consortia.

Colonies of the cyanobacteria act as a biological hotspot for the usage and recycling of key resources such as C, N, P, and Fe within an otherwise oligotrophic environment. While colonies are known to interact and support a unique community of algae and particle-associated microbes, our understanding of the taxa that populate these colonies and the gene functions they encode is still limited. Characterizing the taxa and adaptive strategies that influence consortium physiology and its concomitant biogeochemistry is critical in a future ocean predicted to have increasingly resource-depleted regions.

Meltable Hybrid Antimony and Bismuth Iodide One-Dimensional Perovskites.

Hybrid lead-halide perovskites have been studied extensively for their promising optoelectronic properties and prospective applications, including photovoltaics, solid-state lighting, and radiation detection. Research into these materials has also been aided by the simple and low-temperature synthetic conditions involved in solution-state deposition/crystallization or melt-processing techniques. However, concern over lead toxicity has plagued the field since its infancy.

The Power of Language in Hospital Care for Pregnant and Birthing People: A Vision for Change.

Language is commonly defined as the principal method of human communication made up of words and conveyed by writing, speech, or nonverbal expression. In the context of clinical care, language has power and meaning and reflects priorities, beliefs, values, and culture. Stigmatizing language can communicate unintended meanings that perpetuate socially constructed power dynamics and result in bias.

Deductive automated pollen classification in environmental samples via exploratory deep learning and imaging flow cytometry.

Pollen and tracheophyte spores are ubiquitous environmental indicators at local and global scales. Palynology is typically performed manually by microscopic analysis; a specialised and time-consuming task limited in taxonomical precision and sampling frequency, therefore restricting data quality used to inform climate change and pollen forecasting models. We build on the growing work using AI (artificial intelligence) for automated pollen classification to design a flexible network that can deal with the uncertainty of broad-scale environmental applications.

Long-range, non-local switching of spin textures in a frustrated antiferromagnet.

Antiferromagnetic spintronics is an emerging area of quantum technologies that leverage the coupling between spin and orbital degrees of freedom in exotic materials. Spin-orbit interactions allow spin or angular momentum to be injected via electrical stimuli to manipulate the spin texture of a material, enabling the storage of information and energy. In general, the physical process is intrinsically local: spin is carried by an electrical current, imparted into the magnetic system, and the spin texture will then rotate in the region of current flow.

Qualitative study of states' capacity to support alcohol prevention policies during the COVID-19 pandemic in the USA.

Introduction: The onset of the COVID-19 pandemic accelerated rates of alcohol purchasing and related harms in the USA. The increases followed governors' emergency orders that increased alcohol availability, including the allowance of alcohol home delivery, alcohol to-go from restaurants and bars, and curbside pickup from retailers.

Methods: Semi-structured interviews were conducted with 53 participants involved in state-level alcohol prevention policy across 48 states.

An Elusive Target: Inhibitors of JC Polyomavirus Infection and Their Development as Therapeutics for the Treatment of Progressive Multifocal Leukoencephalopathy.

Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating disease caused by infection with JC Polyomavirus (JCPyV). Despite the identification of the disease and isolation of the causative pathogen over fifty years ago, no antiviral treatments or prophylactic vaccines exist. Disease onset is usually associated with immunosuppression, and current treatment guidelines are limited to restoring immune function.

Gender and Sexual Health-Related Knowledge Gaps and Educational Needs of Parents of Transgender and Non-Binary Youth.

Parents can have a substantial impact on adolescent sexual decision-making, but few studies have explored the role of parents in providing sexual health information to transgender and non-binary (TNB) youth, a population that experiences significant sexual and mental health disparities and lower levels of perceived family support compared with other youth. This study aimed to elucidate existing knowledge gaps and content deemed important for a sexual health curriculum and educational materials for parents of TNB youth. We conducted 21 qualitative interviews with five parents of TNB youth, 11 TNB youth aged 18+, and five healthcare affiliates to identify parents' educational needs.

High fat diet improves metabolic flexibility during progressive exercise to exhaustion (VOmax testing) and during 5 km running time trials.

Recently we reported similar performances in both progressive tests to exhaustion (VOmax) and 5km running time trials (5KTT) after consuming low-carbohydrate, high-fat (LCHF) or high-carbohydrate, low-fat (HCLF) diets. Accordingly, we tested the null hypothesis that the metabolic responses during both tests would be similar across diets. In a randomized, counterbalanced, cross-over design, seven male athletes (VOmax: 61.

Universal health insurance program for people living with HIV in Vietnam: an ambitious approach.

International funding for HIV treatment and prevention drastically decreased when Vietnam transitioned from a low-income to a lower-middle-income country in 2010. Vietnam has attempted to fill the funding gap from both public and private sources to cover antiretroviral therapy (ART) treatment. However, policies that enable social health insurance to pay for ART treatment-related costs often exclude people living with HIV (PLHIV) without appropriate government documents from accessing the health insurance-funded ART program.
