Sleep duration at night affects daytime wake EEG spectra.

Background: Sleep deprivation leads to decreased performance, alertness and degradation in the health status of a person. Often the person remains unaware of the reduced alertness and may end up taking inaccurate decisions. There was a need to study the sleep duration of college goers and to study the effect of total night-time sleep duration on daytime Electroencephalogram (EEG) characteristics.

Simulated Galactic Cosmic Radiation Exposure-Induced Mammary Tumorigenesis in Mice Coincides with Activation of ERα-ERRα-SPP1 Signaling Axis.

Background: Exposure to galactic cosmic radiation (GCR) is a breast cancer risk factor for female astronauts on deep-space missions. However, the specific signaling mechanisms driving GCR-induced breast cancer have not yet been determined.

Methods: This study aimed to investigate the role of the estrogen-induced ERα-ERRα-SPP1 signaling axis in relation to mammary tumorigenesis in female mice exposed to simulated GCR (GCRsim) at 100-110 days post-exposure.

Caring for children with SAM: Intersectional stories of shame, blame and stigmatisation in Zimbabwe, Zambia and Kenya.

This paper draws from qualitative research undertaken with the mothers and primary caregivers of children aged under 5 years old and in recovery from severe acute malnutrition (SAM), as well as other community members, across three study sites in Kenya, Zambia, and Zimbabwe. The paper highlights how nutrition-related stigma is constructed and enacted in complex ways, by multiple actors and across diverse settings. Adopting an intersectional approach, the paper identifies how stigma emerges at the intersections of social identity, especially age, gender, and associated beliefs about women's, and especially young women's, assumed (in)capacity to care.

Search for Soft Unclustered Energy Patterns in Proton-Proton Collisions at 13 TeV.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

Antimicrobial stewardship implementation in primary and secondary tier hospitals in India: interim findings from a need assessment study using mixed method design.

Anti-microbial stewardship program (AMSP) is practiced only in tertiary hospitals in India, though, the lower tier hospitals remain the first point of contact in patient care. This study was conducted in lower tier hospitals to calculate antibiotic and multiple antibiotic prescription rate (APR, MPR) for common infections and finding existing strength of health system for optimizing antibiotic prescription. We conducted a cross sectional convergent parallel mix-method study in eight lower tier hospitals of three districts of West Bengal, India.

The first search for the Z boson decay to ττμμ at the CERN LHC is presented, based on data collected by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 138  fb^{-1}. The data are compatible with the predicted background. For the first time, an upper limit at the 95% confidence level of 6.

Opportunities and challenges for use of minipigs in nonclinical pharmaceutical development: Results of a follow-up IQ DruSafe survey.

Minipigs are valid nonrodent species infrequently utilized for pharmaceutical research and development (R&D) compared with dogs or nonhuman primates (NHPs). A 2022 IQ DruSafe survey revealed a modest increase in minipig use by pharmaceutical companies compared with a prior 2014 survey, primarily in the development of oral small molecules and parenteral protein molecules. Some companies considered using minipigs more often due to NHP shortages and regional ethical concerns with using NHPs and dogs.

Evidence for a sex-dependent effect modification in the association between IFN-λ DNA polymorphisms and expression of IFN-λ and interferon-stimulated genes in human PBMCs.

Human interferon (IFN) lambda (IFNL, IFN-L or IFN-λ) locus has several functional genetic variants but their role in regulating in vivo gene expression, and whether they associate with antiviral states in healthy individuals, is not clear. In this study, we recruited ∼550 healthy individuals belonging to both sexes, genotyped them for several IFNL genetic variants and measured, by qPCR, the expression of IFNL2/3, IFNL4 and four IFN-stimulated genes (ISGs) (MX1, OAS1, ISG15 and RSAD2) from their peripheral blood mononuclear cells (PBMC) both before and after stimulation with a viral mimic, poly I: C. We also measured secreted levels of several cytokines including IFN-λ1 and IFN-λ3 in poly I:C stimulated PBMCs.

A search for collective effects inside jets produced in proton-proton collisions is performed via correlation measurements of charged particles using the CMS detector at the CERN LHC. The analysis uses data collected at a center-of-mass energy of sqrt[s]=13  TeV, corresponding to an integrated luminosity of 138  fb^{-1}. Jets are reconstructed with the anti-k_{T} algorithm with a distance parameter of 0.

Effects of High-Linear-Energy-Transfer Heavy Ion Radiation on Intestinal Stem Cells: Implications for Gut Health and Tumorigenesis.

Heavy ion radiation, prevalent in outer space and relevant for radiotherapy, is densely ionizing and poses a risk to intestinal stem cells (ISCs), which are vital for maintaining intestinal homeostasis. Earlier studies have shown that heavy-ion radiation can cause chronic oxidative stress, persistent DNA damage, cellular senescence, and the development of a senescence-associated secretory phenotype (SASP) in mouse intestinal mucosa. However, the specific impact on different cell types, particularly Lgr5 intestinal stem cells (ISCs), which are crucial for maintaining cellular homeostasis, GI function, and tumor initiation under genomic stress, remains understudied.

Industry Perspective on First-in-Human and Clinical Pharmacology Strategies to Support Clinical Development of T-Cell Engaging Bispecific Antibodies for Cancer Therapy.

T-cell-engaging bispecific antibodies (TCEs) that target tumor antigens and T cells have shown great promise in treating cancer, particularly in hematological indications. The clinical development of TCEs often involves a lengthy first-in-human (FIH) trial with many dose-escalation cohorts leading up to an early proof of concept (POC), enabling either a no-go decision or dose selection for further clinical development. Multiple factors related to the target, product, disease, and patient population influence the efficacy and safety of TCEs.

Convalescing from SAM: The pitfalls and possibilities of caring for vulnerable children in Harare's high-density neighbourhoods.

It is widely recognised that children recovering from Severe Acute Malnutrition (SAM), remain vulnerable to risk of death following hospital discharge due to a wide range of biological and social factors. In light of this heightened risk, we report here on a qualitative study which aimed to better understand the caring contexts that children recovering from SAM were recuperating in within the high density urban and suburban districts of Harare, Zimbabwe. Undertaken with the mothers and other primary caregivers of 10 children enrolled on a large observational cohort study (HOPE-SAM), this paper identifies several dimensions of the women's lives that impede their caring capabilities.

Measurement of Energy Correlators inside Jets and Determination of the Strong Coupling α_{S}(m_{Z}).

Energy correlators that describe energy-weighted distances between two or three particles in a hadronic jet are measured using an event sample of sqrt[s]=13  TeV proton-proton collisions collected by the CMS experiment and corresponding to an integrated luminosity of 36.3  fb^{-1}. The measured distributions are consistent with the trends in the simulation that reveal two key features of the strong interaction: confinement and asymptotic freedom.

A Strategic Synthesis of Orange Waste-Derived Porous Carbon via a Freeze-Drying Method: Morphological Characterization and Cytocompatibility Evaluation.

Porous carbon materials from food waste have gained growing interest worldwide for multiple applications due to their natural abundance and the sustainability of the raw materials and the cost-effective synthetic processing. Herein, orange waste-derived porous carbon (OWPC) was developed through a freeze-drying method to prevent the demolition of the original biomass structure and then was pyrolyzed to create a large number of micro, meso and macro pores. The novelty of this work lies in the fact of using the macro-channels of the orange waste in order to create a macroporous network via the freeze-drying method which remains after the pyrolysis steps and creates space for the development of different types of porous in the micro and meso scale in a controlled way.

Multi-omics analysis delineates resistance mechanisms associated with BRAF inhibition in melanoma cells.

Mutant BRAF is a critical oncogenic driver in melanoma, making it an attractive therapeutic target. However, the success of targeted therapy using BRAF inhibitors vemurafenib and dabrafenib has been limited due to development of resistance, restricting their clinical efficacy. A prior knowledge of resistance mechanisms to BRAFi or any cancer drug can lead to development of drugs that overcome resistance thus improving clinical outcomes.

CT strain metrics allow for earlier diagnosis of bronchiolitis obliterans syndrome after hematopoietic cell transplant.

Bronchiolitis obliterans syndrome (BOS) after hematopoietic cell transplantation (HCT) is associated with substantial morbidity and mortality. Quantitative computed tomography (qCT) can help diagnose advanced BOS meeting National Institutes of Health (NIH) criteria (NIH-BOS) but has not been used to diagnose early, often asymptomatic BOS (early BOS), limiting the potential for early intervention and improved outcomes. Using pulmonary function tests (PFTs) to define NIH-BOS, early BOS, and mixed BOS (NIH-BOS with restrictive lung disease) in patients from 2 large cancer centers, we applied qCT to identify early BOS and distinguish between types of BOS.

Observation of the ϒ(3S) Meson and Suppression of ϒ States in Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV.

The production of ϒ(2S) and ϒ(3S) mesons in lead-lead (Pb-Pb) and proton-proton (pp) collisions is studied in their dimuon decay channel using the CMS detector at the LHC. The ϒ(3S) meson is observed for the first time in Pb-Pb collisions, with a significance above 5 standard deviations. The ratios of yields measured in Pb-Pb and pp collisions are reported for both the ϒ(2S) and ϒ(3S) mesons, as functions of transverse momentum and Pb-Pb collision centrality.

No significant deviations from the background predictions are observed between 1.

Understanding the molecular regulators of neuroendocrine prostate cancer.

Worldwide, prostate cancer (PCa) remains a leading cause of death in men. Histologically, the majority of PCa cases are classified as adenocarcinomas, which are mainly composed of androgen receptor-positive luminal cells. PCa is initially driven by the androgen receptor axis, where androgen-mediated activation of the receptor is one of the primary culprits for disease progression.
