ABSTRACT Background Cerebrospinal fluid (CSF) serves as a medium for nutrient delivery and waste clearance. The T1 relaxation rate, R1, can be used to measure the concentration of intrinsic solutes and extrinsic contrast agents. Purpose To implement a method for R1 mapping and segmentation of CSF and to use this method to explore how R1 of CSF relates ...

The CHESS survey of the L1157-B1 bow-shock: high and low excitation water vapor
Molecular outflows powered by young protostars strongly affect the kinematics and chemistry of the natal molecular cloud through strong shocks resulting in substantial modifications of the abundance of several species.

Ion Activation Methods for Top‐Down Proteomics
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Des sécheresses impactant fortement les forêts se sont déjà produites dans le passé en Europe (1911, à la fin des années 1940, 1976). Les plus récentes des étés 2003, 2018 et 2022, ont été marquées également par des vagues de chaleur sans précédent.

Exercise, exerkines, and muscle–brain crosstalk in Parkinson's disease
Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with motor and non‐motor symptoms, driven by dopaminergic loss and α‐synuclein accumulation. Beyond neurodegeneration, growing evidence highlights skeletal muscle health as a key determinant of prognosis, with sarcopenia and frailty contributing to greater disability, fall ...

Étude comparative des paramètres structuraux des forêts sacrées de la région de l’ouest-Cameroun : cas du département de la Menoua [PDF]
Les forêts sacrées (FS) sont des parcelles de terrain réservées en vue de la pratique de certains rites culturels. Bien de fois, ces forêts sont vues comme des foyers de conservation de certaines essences de bois.

Strong CH^+ J = 1–0 emission and absorption in DR21 [PDF]
We report the first detection of the ground-state rotational transition of the methylidyne cation CH^+ towards the massive star-forming region DR 21 with the HIFI instrument onboard the Herschel satellite. The line profile exhibits a broad emission line,
