Stress responsiveness in a wild primate predicts survival across an extreme El Niño drought.

We know more about the costs of chronic stress than the benefits of the acute stress response-an adaptive response that buffers organisms from life-threatening challenges. As yet, no primate study has empirically identified how the stress response adaptively affects evolutionary fitness. Here, we take advantage of a natural experiment-an El Niño drought-that produced unprecedented mortality for wild white-faced capuchins.

Multisensory integration operates on correlated input from unimodal transient channels.

Audiovisual information reaches the brain via both sustained and transient input channels, representing signals' intensity over time or changes thereof, respectively. To date, it is unclear to what extent transient and sustained input channels contribute to the combined percept obtained through multisensory integration. Based on the results of two novel psychophysical experiments, here we demonstrate the importance of the transient (instead of the sustained) channel for the integration of audiovisual signals.

A Unique Intramolecular Redox Reaction by Unidirectional Migration of Three Hydrogen Atoms: Theoretical Elucidation of the 3H-Transfer Sequence.

The intramolecular migration of three hydrogen atoms from one moiety of a gaseous radical cation to the other prior to fragmentation is an extremely rare type of redox reaction. Within the scope of this investigation, this scenario requires an ionized but electron-rich arene acceptor bearing a para-(3-hydroxyalkyl) residue. The precise mechanism of such unidirectional 3H transfer processes, including the order of the individual H transfer steps, has remained unclear in spite of previous isotope labelling and recent infrared ion spectroscopy (IRIS) studies.

Introduction And Objectives: Balloon atrial septostomy (BAS) improves oxygenation in neonates with transposition of the great arteries (TGA) and restrictive foramen ovale. Currently, there is a global shortage of dedicated BAS catheters, while new unmarked catheters have recently become available at some European centers. This study aimed to characterize BAS outcomes using the currently available BAS catheters in Europe.

Assessing the impact of different donor milk treatments on infant health and growth: a systematic review protocol.

Introduction: Donor human milk (DHM) is the first alternative if mother's own milk is unavailable or contraindicated. Much DHM research has focused on its nutritional, immunological and biochemical composition in response to various maternal variables, standard human milk banking procedures and storage protocols. The current systematic review protocol, however, aims to systematically gather and analyse existing data pertaining to the impact of these aforementioned factors on the clinical, health-related and developmental outcomes observed in infants fed with DHM.

Background Context: Spondylodiscitis management presents significant clinical challenges, particularly in critically ill patients, where the risks and benefits of surgical intervention must be carefully balanced. The optimal timing of surgery in this context remains a subject of debate.

Purpose: This study aims to evaluate the effectiveness of early surgery versus delayed surgery or conservative management in critically ill patients with de novo pyogenic spondylodiscitis.

Membrane potential states gate synaptic consolidation in human neocortical tissue.

Synaptic mechanisms that contribute to human memory consolidation remain largely unexplored. Consolidation critically relies on sleep. During slow wave sleep, neurons exhibit characteristic membrane potential oscillations known as UP and DOWN states.

Teaching Sex- and Gender-Sensitive Medicine Is Not Just a Matter of Content.

Despite a growing integration of sex and gender-sensitive content in medical education around the globe, the focus on content often leads to a lack of consideration of the hidden curriculum. To foster an inclusive, sex- and gender-sensitive culture in medical education, we have to take a holistic approach that transcends a sole focus on explicit teaching content. This article provides reflections about the practice of teaching sex and gender-sensitive medicine focusing on the impactful yet implicit notions we convey about sex and gender in medical education.

Dupilumab Efficacy and Safety in Children With Moderate to Severe Asthma and High Blood Eosinophils: A Post Hoc Analysis of VOYAGE.

Background: Elevated blood or tissue eosinophils are considered to characterize type 2 inflammation in children with asthma and are associated with increased exacerbation rates and worse asthma control. Dupilumab, a human mAb that blocks type 2 inflammatory drivers IL-4 and IL-13, reduced severe exacerbation rates and improved lung function versus placebo in children aged 6 to 11 years with uncontrolled moderate to severe asthma in the phase 3 LIBERTY ASTHMA VOYAGE study (NCT02948959).

Objective: To assess dupilumab efficacy and safety in children from VOYAGE with moderate to severe asthma and greater than or equal to 500 and less than 1500 blood eosinophils/μL at baseline.

Examining health equity in Nepal's climate change and health policies through the lens of environmental justice: insights from a content analysis.

Background: Climate change presents a multifaceted challenge with unequal health implications, particularly for vulnerable populations with limited adaptive capacity. Socioeconomic factors are intricately linked with environmental health outcomes and environmental factors significantly exacerbate existing health inequities. Health equity as a goal of environmental justice can address these issues.

Mortality in septic patients treated with short-acting betablockers: a comprehensive meta-analysis of randomized controlled trials.

Background: Treatment with short-acting betablockers in septic patients remains controversial. Two recent large multicenter trials have provided additional evidence on this therapeutic approach. We thus performed a meta-analysis, including the most recent data, to evaluate the potential impacts of treatment with short-acting betablockers on mortality in adult septic patients.

Global collaborative research in metabolic and bariatric surgery (GCRMBS): current status and directions for the future.

Obesity has been recognized as a chronic disorder by the World Health Organisation (WHO) and was first reported in the Paleolithic age. In the recent years there has not been an international collaborative that facilitates professional cooperation on a worldwide level to increase the output of high-level evidence in the fields of obesity treatment and metabolic and bariatric surgery (MBS). In other surgical and medical fields, international collaborative research networks have shown to increase the quality and amount of treatment-changing evidence.

Perfusion Process Intensification for Lentivirus Production Using a Novel Scale-Down Model.

Process intensification has become an important strategy to lower production costs and increase manufacturing capacities for biopharmaceutical products. In particular for the production of viral vectors like lentiviruses (LVs), the transition from (fed-)batch to perfusion processes is a key strategy to meet the increasing demands for cell and gene therapy applications. However, perfusion processes are associated with higher medium consumption.

A mechanistic integration of hypoxia signaling with energy, redox, and hormonal cues.

Oxygen deficiency (hypoxia) occurs naturally in many developing plant tissues but can become a major threat during acute flooding stress. Consequently, plants as aerobic organisms must rapidly acclimate to hypoxia and the associated energy crisis to ensure cellular and ultimately organismal survival. In plants, oxygen sensing is tightly linked with oxygen-controlled protein stability of group VII ETHYLENE-RESPONSE FACTORs (ERFVII), which, when stabilized under hypoxia, act as key transcriptional regulators of hypoxia-responsive genes (HRGs).

Perception and processing of stress signals by plant mitochondria.

In the course of their life, plants continuously experience a wide range of unfavourable environmental conditions in the form of biotic and abiotic stress factors. The perception of stress via various organelles and rapid, tailored cellular responses are essential for the establishment of plant stress resilience. Mitochondria as the biosynthetic sites of energy equivalents in the form of ATP-provided in order to enable a multitude of biological processes in the cell-are often directly impacted by external stress factors.

NF-κB in Alzheimer's Disease: Friend or Foe? Opposite Functions in Neurons and Glial Cells.

Alzheimer's disease (AD) is a devasting neurodegenerative disease afflicting mainly glutamatergic neurons together with a massive neuroinflammation mediated by the transcription factor NF-κB. A 65%-plus increase in Alzheimer's patients by 2050 might be a major threat to society. Hallmarks of AD are neurofibrillary tangles (NFTs) composed of hyperphosphorylated tau and amyloid beta (Aβ) plaques.

Evaluation of Potency and Specificity of Cryptophycin-Loaded Antibody-Drug Conjugates.

An enhanced variant of the antimitotic toxin cryptophycin was conjugated to the anti-Her2 monoclonal antibody (mAb) Trastuzumab upon Michael addition. Either antibodies with freed hinge-region cysteines or THIOMAB formats with engineered cysteines in the mAbs light chain were added to a maleimide derivative of cryptophycin. These Antibody-Drug Conjugates (ADCs) showed retained binding to Her2 positive tumor cells and highly efficient cell killing in double-digit pM range on high Her2-expressing SK-BR-3 cells.

Prognostic Value of Speckle Tracking Echocardiography-Derived Strain in Unmasking Risk for Arrhythmias in Children with Myocarditis.

Risk assessment in pediatric myocarditis is challenging, particularly when left ventricular ejection fraction (LVEF) is preserved. This study aimed to evaluate LV myocardial deformation using speckle-tracking echocardiography (STE)-derived longitudinal +strain (LS) and assessed its diagnostic and prognostic value in children with myocarditis. Retrospective STE-derived layer-specific LV LS analysis was performed on echocardiograms from patients within the multicenter, prospective registry for pediatric myocarditis "MYKKE".

Confined bicontinuous microemulsions: nanoscale dynamics of the surfactant film.

A confined bicontinuous CE-DO--octane microemulsion is studied using neutron spin echo spectroscopy (NSE). Controlled pore glasses serve as confining matrices with pore diameters ranging from 24 to 112 nm. Firstly, the microemulsion in bulk is investigated by NSE and dynamic light scattering, which allows the determination of the unperturbed collective dynamics as well as the observation of the undulation of the surfactant film.
