Oral hygiene of stroke patients in a stroke unit: a best practice implementation project.

Introduction: People with stroke are at risk of poor oral hygiene caused by neurological deficits, which can be motor, sensory, or cognitive. Good oral hygiene has been shown to reduce adverse events and improve the patient's quality of life. Although nurses recognize the benefits of oral hygiene, evidence shows that this area of care is frequently overlooked.

Peripherally administered TNF inhibitor is not protective against α-synuclein-induced dopaminergic neuronal death in rats.

The underlying cause of neuronal loss in Parkinson's disease (PD) remains unknown, but evidence implicates neuroinflammation in PD pathobiology. The pro-inflammatory cytokine soluble tumor necrosis factor (TNF) seems to play an important role and thus has been proposed as a therapeutic target for modulation of the neuroinflammatory processes in PD. In this regard, dominant-negative TNF (DN-TNF) agents are promising antagonists that selectively inhibit soluble TNF signaling, while preserving the beneficial effects of transmembrane TNF.

Comparing adenosine A receptor modulation of cannabinoid CB receptor-mediated inhibition of GABA and glutamate release in rodent striatal nerve terminals.

In corticostriatal nerve terminals, glutamate release is stimulated by adenosine via A receptors (ARs) and simultaneously inhibited by endocannabinoids via CB receptors (CBRs). We previously identified presynaptic AR-CBR heterotetrameric complexes in corticostriatal nerve terminals. We now explored the possible functional interaction between ARs and CBRs in purified striatal GABAergic nerve terminals (synaptosomes) and compared these findings with those on the release of glutamate.

Sex differences in mitochondrial free-carnitine levels in subjects at-risk and with Alzheimer's disease in two independent study cohorts.

A major challenge in the development of more effective therapeutic strategies for Alzheimer's disease (AD) is the identification of molecular mechanisms linked to specific pathophysiological features of the disease. Importantly AD has a two-fold higher incidence in women than men and a protracted prodromal phase characterized by amnestic mild-cognitive impairment (aMCI) suggesting that biological processes occurring early can initiate vulnerability to AD. Here, we used a sample of 125 subjects from two independent study cohorts to determine the levels in plasma (the most accessible specimen) of two essential mitochondrial markers acetyl-L-carnitine (LAC) and its derivative free-carnitine motivated by a mechanistic model in rodents in which targeting mitochondrial metabolism of LAC leads to the amelioration of cognitive function and boosts epigenetic mechanisms of gene expression.

Main Methods: We utilized an HNF4α knockout (KO) mouse model, with CRE-recombinase enzyme activation confirmed through tamoxifen administration. KO and Control (CTL) mice were fed an HFD for 20 weeks.

Spatial transcriptomic analysis drives PET imaging of tight junction protein expression in pancreatic cancer theranostics.

Molecular imaging using positron emission tomography (PET) provides sensitive detection and mapping of molecular targets. While cancer-associated fibroblasts and integrins have been proposed as targets for imaging of pancreatic ductal adenocarcinoma (PDAC), herein, spatial transcriptomics and proteomics of human surgical samples are applied to select PDAC targets. We find that selected cancer cell surface markers are spatially correlated and provide specific cancer localization, whereas the spatial correlation between cancer markers and immune-related or fibroblast markers is low.

From plastic waste to bioprocesses: Using ethylene glycol from polyethylene terephthalate biodegradation to fuel metabolism and produce value-added compounds.

Polyethylene Terephthalate (PET) is a petroleum-based plastic polymer that, by design, can last decades, if not hundreds of years, when released into the environment through plastic waste leakage. In the pursuit of sustainable solutions to plastic waste recycling and repurposing, the enzymatic depolymerization of PET has emerged as a promising green alternative. However, the metabolic potential of the resulting PET breakdown molecules, such as the two-carbon (C2) molecule ethylene glycol (EG), remains largely untapped.

Shades of red: A chemical exploration of pigments and dyes in 19th century postage stamps by a multi-analytical methodology.

A total of 57 European, Canadian and North American postage stamps, all in red shades, were analyzed with the main goal of unraveling which pigments or dyes were used to produce the red color in the period dated from 1841 to 1899. Both non-destructive techniques, including X-Ray Fluorescence (XRF), Fiber Optics Reflectance Spectra (FORS), and Steady State Fluorescence Spectroscopy, and destructive methods such as High-Performance Liquid Chromatography coupled with Diode-Array Detection (HPLC-DAD) and Electrospray Ionization High-Resolution Mass Spectrometry (ESI-HRMS), were utilized for a comprehensive analysis. The examined red shades were identified as originating from either a single pigment or dye, or a combination of both.

A modelling framework to characterize the impact of antibiotics on the gut microbiota diversity.

Metagenomic sequencing deepened our knowledge about the role of the intestinal microbiota in human health, and several studies with various methodologies explored its dynamics during antibiotic treatments. We compared the impact of four widely used antibiotics on the gut bacterial diversity. We used plasma and fecal samples collected during and after treatment from healthy volunteers assigned to a 5-day treatment either by ceftriaxone (1 g every 24 h through IV route), ceftazidime/avibactam (2 g/500 mg every 8 h through IV route), piperacillin/tazobactam (1 g/500 mg every 8 h through IV route) or moxifloxacin (400 mg every 24 h through oral route).
