Optimizing Immunohistochemistry Reporting in Endometrial Cancer.

The management of endometrial cancer involves a multidisciplinary team (MDT) approach, with immunohistochemistry playing an important role in management and prognosis. Markers investigated include estrogen receptor (ER), progesterone receptor (PR), tumor protein 53 (p53), and mismatch repair(MMR) protein. Additionally, polymerase epsilon (POLE) mutations indicate treatment-responsive tumors, often with excellent prognosis.

Mitochondrial Dysfunction and Fatigue in Sjögren's Disease.

Objectives: Sjögren's disease (SjD) is a common exocrine disorder typified by chronic inflammation and dryness, but also profound fatigue, suggesting a pathological basis in cellular bioenergetics. In healthy states, damaged or dysfunctional mitochondrial components are broken down and recycled by mitophagy, a specialized form of autophagy. In many autoimmune disorders, however, evidence suggests that dysfunctional mitophagy allows poorly functioning mitochondria to persist and contribute to a cellular milieu with elevated reactive oxygen species.

Rehabilitation Techniques for Adults Undergoing External Fixation Treatment for Lower Limb Reconstruction: A Systematic Review.

Introduction: External fixation devices are commonly used in orthopaedic surgery to manage a range of pathologies. In this patient population, there is currently no consensus on optimal rehabilitation techniques. There exists a large variation in practice, with a limited understanding of how these affect treatment outcomes.

A mutant allele of glycoprotein M6-B (Gpm6b) facilitates behavioral flexibility but increases delay discounting.

The neuronal membrane glycoprotein M6B (Gpm6b) gene encodes a membrane glycoprotein that belongs to the proteolipid protein family, and is enriched in neurons, oligodendrocytes, and subset of astrocytes in the central nervous system. GPM6B is thought to play a role in neuronal differentiation, myelination, and inactivation of the serotonin transporter via internalization. Recent human genome-wide association studies (GWAS) have implicated membrane glycoproteins (both GPM6B and GPM6A) in the regulation of traits relevant to psychiatric disorders, including neuroticism, depressed affect, and delay discounting.

Serologic markers of Epstein-Barr virus reactivation are associated with increased disease activity, inflammation, and interferon pathway activation in patients with systemic lupus erythematosus.

SLE is a clinically heterogeneous disease characterized by an unpredictable relapsing-remitting disease course. Although the etiology and mechanisms of SLE flares remain elusive, Epstein-Barr virus (EBV) reactivation is implicated in SLE pathogenesis. This study examined the relationships between serological measures of EBV reactivation, disease activity, and interferon (IFN)-associated immune pathways in SLE patients.

Sleep and Diet: Mounting Evidence of a Cyclical Relationship.

Two factors intrinsic to health are diet and sleep. These two behaviors may well influence one another. Indeed, that insufficient sleep adversely impacts dietary intakes is well documented.

The impact of cultural beliefs and practices on parents' experiences of bereavement following stillbirth: a qualitative study in Uganda and Kenya.

Background: Stillbirth is an extremely traumatic and distressing experience for parents, with profound and long-lasting negative impacts. Cultural beliefs and practices surrounding death vary considerably across different contexts and groups, and are a key influence on individual experiences, impacting grief, adjustment, and support needs. Few studies have explored cultural influences surrounding stillbirth in an African context.

A Phase II study of nab-Paclitaxel (nab-P) in patients with advanced non-small cell lung cancer with EGFR mutations after frontline tyrosine kinase inhibitor therapy.

Background: Patients with metastatic non-small cell lung cancer (NSCLC) harboring a sensitizing EGFR mutation have effective targeted therapy options initially but most patients eventually progress and receive cytotoxic chemotherapy. In this single-institution phase II study, we evaluated the role of nab-paclitaxel monotherapy in this patient population.

Patients And Methods: Patients with metastatic NSCLC with an activating EGFR mutation whose disease progressed after frontline tyrosine kinase inhibitor therapy and who were chemotherapy naïve received nab-paclitaxel 125 mg/m2 on days 1, 8 and 15 in a 28-day cycle.

Effects of maternal mental health on prenatal movement profiles in twins and singletons.

Aim: Prenatal experiences, including maternal stress, depression and anxiety, form crucial building blocks affecting the maturation of the foetal central nervous system. Previous research has examined foetal movements without considering effects of maternal mental health factors critical for healthy foetal development. The aim of this research is to assess the effects of maternal mental health factors on foetal twin compared with singleton movement profiles.

The experiences and psychological outcomes for pregnant women who have had FGM: A systematic review.

Female genital mutilation (FGM) is a global issue, with 200 million women and girls thought to be affected. FGM is defined as removal of female external genitalia, either partial or total, for non-medical purposes. FGM is embedded in tradition, including cultural beliefs about sexual behaviour.

Cross-skilling training to support medical redeployment in the COVID-19 pandemic.

During the response to the COVID-19 pandemic, doctors will be redeployed into roles with which they are unfamiliar. Adequate training must be provided to reacquaint doctors with medical ward practice, supporting psychological wellbeing and patient safety. Here we describe a cross-skilling programme in North Bristol NHS Trust designed to address colleague anxiety and support wellbeing during redeployment.

Tollip coordinates Parkin-dependent trafficking of mitochondrial-derived vesicles.

Multiple mitochondrial quality control pathways exist to maintain the health of mitochondria and ensure cell homeostasis. Here, we investigate the role of the endosomal adaptor Tollip during the mitochondrial stress response and identify its interaction and colocalisation with the Parkinson's disease-associated E3 ubiquitin ligase Parkin. The interaction between Tollip and Parkin is dependent on the ubiquitin-binding CUE domain of Tollip, but independent of Tom1 and mitophagy.

Relationships between drinking quantity and frequency and behavioral and hippocampal BOLD responses during working memory performance involving allocentric spatial navigation in college students.

Background: Quantity and frequency of drinking may be used to effectively quantify the severity of alcohol-use. Drinking-severity has been related to neurocognitive impairments in such domains as spatial working memory (SWM). Youth drinking has been associated with altered neurofunctional underpinnings of SWM.

A qualitative study of partner engagement in HIV testing in Malawi and Kenya.

In low-income settings, partner engagement in HIV testing during pregnancy is well recognised, but uptake remains low. To understand why men fail to engage, 76 in-depth, individual interviews were conducted with women ( = 23), men ( = 36) and community stakeholders ( = 17) in Malawi and Kenya. Transcribed data were analysed thematically.

Relationship between fMRI response during a nonverbal memory task and marijuana use in college students.

Marijuana (MJ) is widely used among college students, with peak use between ages 18-22. Research suggests memory dysfunction in adolescent and young adult MJ users, but the neural correlates are unclear. We examined functional magnetic resonance imaging (fMRI) response during a memory task among college students with varying degrees of MJ involvement.

Longitudinal Effects of Alcohol Consumption on the Hippocampus and Parahippocampus in College Students.

Background: The hazardous effects of alcohol consumption on both the hippocampus and memory have been well established. However, the longitudinal effects of ethanol on the developing brain and related consequences on memory are not well explored. Given the above, we investigated the longitudinal effects of college drinking on hippocampal volume in emerging college adults.

A biosensor-based framework to measure latent proteostasis capacity.

The pool of quality control proteins (QC) that maintains protein-folding homeostasis (proteostasis) is dynamic but can become depleted in human disease. A challenge has been in quantitatively defining the depth of the QC pool. With a new biosensor, flow cytometry-based methods and mathematical modeling we measure the QC capacity to act as holdases and suppress biosensor aggregation.

An Expanded Heterologous GAL Promoter Collection for Diauxie-Inducible Expression in Saccharomyces cerevisiae.

The GAL promoters are applied in metabolic engineering and synthetic biology to control gene expression in the budding yeast Saccharomyces cerevisiae. In gal80Δ background strains, they show diauxie-inducible expression, a feature beneficial in metabolic pathway optimization. However, only a limited number of GAL promoters have been characterized and are available for engineering purposes.

Heavy Drinking in College Students Is Associated with Accelerated Gray Matter Volumetric Decline over a 2 Year Period.

Heavy and/or harmful alcohol use while in college is a perennial and significant public health issue. Despite the plethora of cross-sectional research suggesting deleterious effects of alcohol on the brain, there is a lack of literature investigating the longitudinal effects of alcohol consumption on the adolescent brain. We aim to probe the longitudinal effects of college drinking on gray matter change in students during this crucial neurodevelopmental period.

A thiol probe for measuring unfolded protein load and proteostasis in cells.

When proteostasis becomes unbalanced, unfolded proteins can accumulate and aggregate. Here we report that the dye, tetraphenylethene maleimide (TPE-MI) can be used to measure cellular unfolded protein load. TPE-MI fluorescence is activated upon labelling free cysteine thiols, normally buried in the core of globular proteins that are exposed upon unfolding.

No. 245-Alcohol Use and Pregnancy Consensus Clinical Guidelines.

Objective: To establish national standards of care for the screening and recording of alcohol use and counselling on alcohol use of women of child-bearing age and pregnant women based on the most up-to-date evidence.

Evidence: Published literature was retrieved through searches of PubMed, CINAHL, and the Cochrane Library in May 2009 using appropriate controlled vocabulary (e.g.

Chronic effects of atrazine exposure and recovery in freshwater benthic diatoms from two communities with different pollution histories.

Diffuse agricultural runoff into rivers can result in contamination with herbicides for prolonged periods of time. Chronic exposure to herbicides has the potential to alter toxic impacts in primary producers such as benthic diatoms. Determining how individual diatom taxa respond to herbicide exposure over varied exposure durations is essential for assessing herbicide impacts.
