Apparatus for skidding sensitivity testing of energetic materials.

A remote-operated apparatus for testing the detonation sensitivity of energetic materials is detailed. Using an air ram and rotating disk, the normal force and transverse velocity of the impact plane are controlled independently, enabling the exploration of varying impact conditions over a wide parameter space. A microcontroller local to the apparatus is used to automate apparatus operation and ensure temporal alignment of the impacting ram head with the rotating disk.

A review on gut microbiota: a central factor in the pathophysiology of obesity.

Obesity and its complications constitute a substantial burden. Considerable published research describes the novel relationships between obesity and gut microbiota communities. It is becoming evident that microbiota behave in a pivotal role in their ability to influence homeostatic mechanisms either to the benefit or detriment of host health, the extent of which is not fully understood.

Artemisia scoparia promotes adipogenesis in the absence of adipogenic effectors.

Objective: Extracts of Artemisia scoparia (SCO) have antidiabetic properties in mice and enhance adipogenesis in vitro, but the underlying mechanisms are unknown. Thiazolidinediones, including rosiglitazone (ROSI), are pharmacological activators of peroxisome proliferator-activated receptor gamma that also promote adipogenesis. The aim of this study was to examine adipogenic pathways responsible for SCO-mediated adipogenesis and identify potential differences between SCO and ROSI in the ability to promote adipocyte development.

Patient Characteristics and Risk Factors in Invasive Mold Infections: Comparison from a Systematic Review and Database Analysis.

Introduction: Diagnosis and treatment of invasive mold infections (IMI) can be challenging and IMI is a significant source of morbidity and mortality. Invasive aspergillosis (IA) and invasive mucormycosis (IM) are two of the most common mold infections. A better understanding of patient comorbidities and risk factors that predispose IMI may help clinicians to refine the difficult diagnostic and treatment process.

Outcomes Associated With High- Versus Low-Frequency Laboratory Testing Among Hospitalized Children.

Background And Objectives: Previous pediatric studies have revealed substantial variation in laboratory testing for specific conditions, but clinical outcomes associated with high- versus low-frequency testing are unclear. We hypothesized that hospitals with high- versus low-testing frequency would have worse clinical outcomes.

Methods: We conducted a multicenter retrospective cohort study of patients 0 to 18 years old with low-acuity hospitalizations in the years 2018-2019 for 1 of 10 common All Patient Refined Diagnosis Related Groups.

Economic and Humanistic Burden Associated with Depression and Anxiety Among Adults with Non-Communicable Chronic Diseases (NCCDs) in the United States.

Introduction: Patients with both major depressive disorder (MDD) and generalized anxiety disorder (GAD) in addition to one or multiple comorbid non-communicable chronic diseases (NCCDs) face unique challenges. However, few studies have characterized how the burden of co-occurring MDD and GAD differs from that of only MDD or only GAD among patients with NCCDs.

Methods: In this study, we used Medical Expenditures Panel Survey data from 2010-2017 to understand how the economic and humanistic burden of co-occurring MDD and GAD differs from that of MDD or GAD alone among patients with NCCDs.

Biosimilar pegfilgrastim may offer affordable treatment options for patients in France: a budget impact analysis on the basis of clinical trial and real-world data.

Background: NYVEPRIA, a pegfilgrastim (a long-acting granulocyte colony-stimulating factor [G-CSF]) biosimilar, was recently recommended for marketing authorization in Europe for decreasing the incidence of febrile neutropenia (FN) in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs. The present study aimed to evaluate the financial impact of introducing a new pegfilgrastim biosimilar from a French healthcare system perspective.

Methods: An Excel-based budget impact model was developed to estimate the financial impact by introducing a new pegfilgrastim biosimilar (NYVEPRIA) to France over a 5-year time horizon.

Adipocyte Oncostatin Receptor Regulates Adipose Tissue Homeostasis and Inflammation.

Adipocytes are the largest cell type in terms of volume, but not number, in adipose tissue. Adipocytes are prominent contributors to systemic metabolic health. Obesity, defined by excess adipose tissue (AT), is recognized as a low-grade chronic inflammatory state.

Prenylated Coumaric Acids from Beneficially Modulate Adipogenesis.

Two new diprenylated coumaric acid isomers ( and ) and two known congeners, capillartemisin A () and B (), were isolated from as bioactive markers using bioactivity-guided HPLC fractionation. Their structures were determined by spectroscopic means, including 1D and 2D NMR methods and LC-MS, with their purity assessed by 1D H pure shift qNMR spectroscopic analysis. The bioactivity of compounds was evaluated by enhanced accumulation of lipids, as measured using Oil Red O staining, and by increased expression of several adipocyte marker genes, including adiponectin in 3T3-L1 adipocytes relative to untreated negative controls.

Mycosands: Fungal diversity and abundance in beach sand and recreational waters - Relevance to human health.

The goal of most studies published on sand contaminants is to gather and discuss knowledge to avoid faecal contamination of water by run-offs and tide-retractions. Other life forms in the sand, however, are seldom studied but always pointed out as relevant. The Mycosands initiative was created to generate data on fungi in beach sands and waters, of both coastal and freshwater inland bathing sites.

The impact of discrimination on allostatic load in adults: An integrative review of literature.

Objective: The objective of the paper is to critically review the current state of the literature on the association between discrimination and allostatic load (AL) in adults and determine whether this association differs by sociodemographic characteristics.

Methods: An extensive literature search was conducted in PubMed, CINAHL, PsycINFO, and Embase to identify studies that investigated the association between discrimination and AL. The search was limited to the English language, articles that were peer-reviewed and articles that were published within the last 10 years.

Raised serum amylase in patients with COVID-19 may not be associated with pancreatitis.

A high incidence of pancreatitis in COVID-19 has been reported. Although a high proportion of critically unwell patients with COVID-19 have raised serum amylase levels, this does not necessarily reflect acute pancreatitis or a clinically important pancreatic injury.

COVID/HIV Co-Infection: A Syndemic Perspective on What to Ask and How to Answer.

The present commentary explored the intersecting nature of the COVID-19 and HIV pandemics to identify a shared research agenda using a syndemic approach. The research agenda posits the following questions. Questions around HIV infection, transmission, and diagnosis include: (i) molecular, genetic, clinical, and environmental assessments of COVID-19 in people living with HIV, (ii) alternative options for facility-based HIV testing services such as self- and home-based HIV testing, and (iii) COVID-19 related sexual violence and mental health on HIV transmission and early diagnosis.

Non-invasive brain stimulation to assess neurophysiologic underpinnings of lower limb motor impairment in multiple sclerosis.

Background: Multiple sclerosis (MS) is a neuroinflammatory disease resulting in axonal demyelination and an amalgamation of symptoms which commonly result in decreased quality of life due to mobility dysfunction and limited participation in meaningful activities.

New Method: The use of non-invasive brain stimulation (NIBS) techniques, specifically transcranial magnetic and transcranial direct current stimulation, have been essential in understanding the pathophysiological decrements related to disease progression, particularly with regard to motor impairments. Although the research in this area has primarily focused on the upper extremities, new interest has arisen in understanding the neurophysiological underpinnings of lower limb impairment.

Can Online Academic Integrity Instruction Affect University Students' Perceptions of and Engagement in Academic Dishonesty? Results From a Natural Experiment in New Zealand.

The problem of academic dishonesty is as old as it is widespread - dating back millennia and perpetrated by the majority of students. Attempts to promote academic integrity, by comparison, are relatively new and rare - stretching back only a few hundred years and implemented by a small fraction of schools and universities. However, the past decade has seen an increase in efforts among universities to promote academic integrity among students, particularly through the use of online courses or tutorials.

Emotion regulation in the face of loss: How detachment, positive reappraisal, and acceptance shape experiences, physiology, and perceptions in late life.

How individuals regulate emotions in the face of loss has important consequences for well-being and health, but we know little about which emotion regulation strategies are most effective for older adults for whom loss is ubiquitous. The present laboratory-based study examined effects of three emotion regulation strategies (i.e.

Improving the replicability of neuroimaging findings by thresholding effect sizes instead of p-values.

The classical approach for testing statistical images using spatial extent inference (SEI) thresholds the statistical image based on the p-value. This approach has an unfortunate consequence on the replicability of neuroimaging findings because the targeted brain regions are affected by the sample size-larger studies have more power to detect smaller effects. Here, we use simulations based on the preprocessed Autism Brain Imaging Data Exchange (ABIDE) to show that thresholding statistical images by effect sizes has more consistent estimates of activated regions across studies than thresholding by p-values.
