NADH Intraperitoneal Injection Prevents Lung Inflammation in a BALB/C Mice Model of Cigarette Smoke-Induced Chronic Obstructive Pulmonary Disease.

Cigarette smoke is one of the main factors in Chronic Obstructive Pulmonary Disease (COPD), a respiratory syndrome marked by persistent respiratory symptoms and increasing airway obstruction. Perturbed NAD+/NADH levels may play a role in various diseases, including lung disorders like COPD. In our study, we investigated the preventive effect of NADH supplementation in an experimental model of COPD induced by cigarette smoke extract (CSE).

The impact of CBz-PAI interlayer in various HTL-based flexible perovskite solar cells: A drift-diffusion numerical study.

In perovskite solar cells (PSCs), the charge carrier recombination obstacles mainly occur at the ETL/perovskite and HTL/perovskite interfaces, which play a decisive role in the solar cell performance. Therefore, this study aims to enhance the flexible PSC (FPSC) efficiency by adding the newly designed CBz-PAI-interlayer (simply CBz-PAI-IL) at the perovskite/HTL interface. In addition, substantial work has been carried out on five different HTLs (Se/Te-CuO, CuGaO, VO and CuSCN, including conventional Spiro-OMeTAD as a reference HTL with and without CBz-PAI-IL), using drift-diffusion simulation to find suitable FPSC design to attain the maximum PCE.

NADH intraperitoneal injection prevents massive pancreatic beta cell destruction in a streptozotocin-induced diabetes in rats.

Diabetes mellitus is a chronic metabolic disease characterized by persistent hyperglycemia, revealing a decrease in insulin efficiency. The sustained glucotoxic pancreatic microenvironment increases reactive oxygen species generation, resulting in chronic oxidative stress responsible for massive DNA damage. This triggers PARP-1 activation with both NAD and ATP depletion, affecting drastically pancreatic beta cells' energy storage and leading to their dysfunction and death.

Physical properties of Be-Based fluoroperovskite compounds XBeF(X = K, Rb): a first-principles study.

In this work, we have conducted an ab initio computational research of the pressure impact on the structural, elastic, thermodynamic, electronic, and optical properties of Be-based fluoroperovskite XBeF3 (X= K, Rb) compounds by using GGA+ PBEsol functional based on DFT in the CASTEP Package. These compounds' ground state characteristics were examined, including the lattice parameters, coefficient compressibility (B), and its pressure derivative(B'). Structural characterization shows that these compounds keep a cubic crystal structure with the impact of stress till 18 GPa.

The Light/Dark cycle disruption affects hepatic function both in metabolic parameters and tissue structure in a nocturnal desert rodent: Gerbillus tarabuli.

Introduction: Biological rhythms, such as Light/Dark (LD) cycles, are an integral component of virtually all aspects of life. These rhythms are controlled in large part by circadian clocks, allowing the organism to adapt its internal rhythmic metabolism to changes in the external environment created by daily fluctuations in the LD cycle. Therefore, changes in the daily duration of the lighting could lead to adverse health consequences.

Prevalence of coccidian infection in rabbit farms in North Algeria.

Aim: The aim of the present study was to determine the prevalence and intensity of rabbit coccidiosis () in North Algeria.

Materials And Methods: During the study, 40 rabbit farms were investigated. The farms are located in the provinces of Tizi Ouzou, Médéa, and Djelfa which distributed, respectively, into three regions: East Tell Atlas Mountains, Central Tell Atlas Mountains, and High Plateaus.

A vaccination trial with a precocious line of Eimeria magna in Algerian local rabbits Oryctolagus cuniculus.

Coccidiosis is a major health problem in rabbits. A vaccine using Eimeria with perfect safety and effectiveness seems to be necessary to face this parasitosis. To assess the safety and the efficacy of a vaccine based on the Algerian precocious line of Eimeria magna against rabbit coccidiosis, twenty eight young rabbits from six litters of Coccidia free females were used to monitor oocystal excretion and body weights, they were distributed into four groups (vaccinated-challenged group, double challenged non vaccinated group, simple challenged non vaccinated group and control group).
