Proteomic analysis of Trichoderma harzianum secretome and their role in the biosynthesis of zinc/iron oxide nanoparticles.

The fungal green synthesis of nanoparticles (NPs) has gained great interest since it is a cost-effective and easy handling method. The process is simple because fungi secrete metabolites and proteins capable of reducing metal salts in aqueous solution, however the mechanism remains largely unknown. The aim of this study was to analyze the secretome of a Trichoderma harzianum strain during the mycobiosynthesis process of zinc and iron nanoparticles.

Local regulation of striatal dopamine release shifts from predominantly cholinergic in mice to GABAergic in macaques.

Dopamine critically regulates neuronal excitability and promotes synaptic plasticity in the striatum, thereby shaping network connectivity and influencing behavior. These functions establish dopamine as a key neuromodulator, whose release properties have been well-studied in rodents but remain understudied in nonhuman primates. This study aims to close this gap by investigating the properties of dopamine release in macaque striatum and comparing/contrasting them to better-characterized mouse striatum, using ex vivo brain slices from male and female animals.

Chemerin is a new sex-specific target in aortic stenosis concomitant with diabetes regulated by the aldosterone/mineralocorticoid receptor axis.

Diabetes mellitus (DM) increases the risk of aortic stenosis (AS) and worsens its pathophysiology in a sex-specific manner. Aldosterone/mineralocorticoid receptor (Aldo/MR) pathway participates in early stages of AS and in other diabetic-related cardiovascular complications. We aim to identify new sex-specific Aldo/MR targets in AS complicated with DM.

SHARD: an improved method for staining and visualizing multiplex immunofluorescence in optically cleared postmortem human brain tissue.

Postmortem human brain tissue is a critical resource for studying neurodegenerative disease, providing critical insights into cellular morphology, pathology, and network connectivity. To improve standard microscopy and enable high-resolution, three-dimensional (3D) images of tissues at the subcellular level, tissue-clearing methods have been developed. These 3D images allow for the analysis of large regions of interest and can be used to study structural and spatial changes that occur during neurodegeneration.

Atrial fibrillation versus non-atrial fibrillation coronary embolism.

Background: Coronary embolism (CE) is an uncommon cause of non-atherosclerotic acute myocardial infarction (AMI). Although atrial fibrillation (AF) is the main cause of CE, evidence of clinical, biochemical, echocardiographic, angiographic findings and outcomes of AF CE is lacking.

Methods: We retrospectively analyzed 85 consecutive patients with CE that was diagnosed based on criteria encompassing clinical, angiographic and diagnostic imaging findings.

Assessing the association between common functional Nuclear Factor Kappa-b gene polymorphisms (NFKB1, NFKBIZ, NFKBIA) and Alzheimer´s disease.

The Nuclear Factor Kappa-b (NF-Κb) pathway has been implicated in the pathogenesis of Alzheimer´s disease (AD). We determined whether common variants in the NF-Κb genes were associated with the risk of developing late-onset AD (LOAD). A total of 639 Spanish LOAD and 500 controls were genotyped for the NFKB1 rs28362491/rs7667496, NFKBIA rs696, NFKBIZ rs3217713 and APOE-Ɛ2/3/4 polymorphisms.

Connecting genomic and proteomic signatures of amyloid burden in the brain.

Background: Alzheimer's disease (AD) has a high heritable component characteristic of complex diseases, yet many of the genetic risk factors remain unknown. We combined genome-wide association studies (GWAS) on amyloid endophenotypes measured in cerebrospinal fluid (CSF) and positron emission tomography (PET) as surrogates of amyloid pathology, which may be helpful to understand the underlying biology of the disease.

Methods: We performed a meta-analysis of GWAS of CSF Aβ42 and PET measures combining six independent cohorts (n=2,076).

Relevance of Continuous EEG versus Routine EEG for Outcome Prediction after Traumatic Brain Injury.

Introduction: In a cohort of adult patients with disturbance of consciousness after TBI, we aimed to explore the relationship of continuous video-EEG (cEEG) versus routine EEG (rEEG) with mortality and functional outcome.

Methods: This is a post hoc analysis of a randomized controlled trial (CERTA), in which adults with disorder of consciousness and needing EEG (excluding those with proven seizures/SE just before) were randomized 1:1 to cEEG or two rEEG. In TBI patients, correlation between EEG duration, mortality, and modified Rankin score (mRs, good 0-2) at 6 months was assessed.

Clinical and Neuropathological Correlates of Substance Use in American Football Players.

Background: Chronic traumatic encephalopathy (CTE) is a neurodegenerative tauopathy more frequently found in deceased former football players.

Rethinking Human Factors in Obesity: Development of Simulation and Physical Test Models of Human Soft Tissue to Study Autoinjector Activation Performance.

Activation against a hard surface according to ISO 11608-1 is not always representative of device use on a soft injection site. A softer injection site - which is an anthropometric property found in obese patients - presents a distinct viscoelastic property which can lead to greater autoinjector activation forces that are not captured in standardized activation testing methodology. Soft tissue simulation and physical testing were developed at SHL to advance the development of autoinjectors, allowing for rigorous testing and challenging these in scenarios involving even the softest injection sites.
