Création de haies-vives par semis directs : problématique, premières expérimentations en Nord Côte d'Ivoire [PDF]

open access: yes, 1992
La délimitation du parcellaire ·par des haie-vive est un domaine en pleine extension en milieu paysan sénoufo. Depuis 1988, la station de Korhogo du Département Foresterie de l'Institut des Forêts (IDEFOR-DFO) de Côte d'Ivoire mène, avec l'appui du ...

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

open access: yesChemistry – A European Journal, EarlyView.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

Structural and Biological Insights Into Copper(I) Phosphane Complexes With Boron‐Phenylated Poly(3‐(CF3)Pyrazolyl)‐ and Poly(6‐(CF3)‐2‐pyridyl)‐Borates

open access: yesChemistry – A European Journal, EarlyView.
This study reports six new copper(I) complexes with unusual coordination and strong anticancer activity against a panel of human cancer cell lines derived from different solid tumors. The most active compounds outperform cisplatin, even in resistant cells, by inhibiting protein disulfide isomerase and inducing redox stress that triggers non‐apoptotic ...

Embryonic cerebrospinal fluid pressure in fetal mice in utero: External factors pressurize the intraventricular space

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Previous experiments inducing leakage of embryonic cerebrospinal fluid (CSF) suggest the necessity of intraventricular CSF pressure (PCSF) for brain morphogenesis. Nevertheless, how embryonic PCSF occurs is unclear, especially in utero. Results Using a Landis water manometer, we measured PCSF in fetal mice isolated from the amniotic

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Evaluating the Air Respiratory Capacity of Awaous (Chonophorus) tajasica (Gobiiformes: Oxudercidae): A Morpho‐Functional Study

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.

Oral PHGG ameliorates atopic dermatitis‐like dermatitis with concurrent modulation of colonic IgA and cecal microbiota: implications for the gut–skin axis

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Atopic dermatitis (AD) is increasingly recognized as a systemic inflammatory disorder linked to intestinal immune and microbiome dysregulation. However, whether dietary galactomannan fibers can mitigate AD through coordinated modulation of the gut–skin axis remains unexplored.
