Impact of Body Reserves Dynamic on Productivity and Reproductive Performance in Fat-Tail and Thin-Tail Sheep Breeds over Contrasting Production Cycles.

Under climate change, animal breeding faces severe nutritional challenges, exhibiting their resilience and efficiency to survive and produce. The animals' robustness can be evaluated through the use and reconstitution of body reserves (BR). This study investigated the dynamics of ewes' BR, measured through body weight (BW) and the body condition score (BCS), and their effect on production performances of 480 ewes belonging to fat-tailed Barbarine (BB) and thin-tailed Queue Fine de l'Ouest (QFO) ewes over two consecutive years.

Screening for drought tolerance and genetic diversity of wheat varieties using agronomic and molecular markers.

Background: The future predictions for frequent and severe droughts will represent a significant threat to wheat yield and food security. In this context, breeding has proven to be the most efficient approach to enhance wheat productivity in dry environments.

Methods And Results: In this study, both agronomic and molecular-based approaches were used to evaluate the response of twenty-eight Tunisian wheat varieties to drought stress.

A theoretical and electrochemical impedance spectroscopy study of the adsorption and sensing of selected metal ions by 4-morpholino-7-nitrobenzofuran.

The selectivity of a novel chemosensor, based on a modified nitrobenzofurazan referred to as NBD-Morph, has been investigated for the detection of heavy metal cations (Co, Pb, Mg, Ag, Cu, Hg, Ni2+, and Zn). The ligand, 4-morpholino-7-nitrobenzofurazan (NBD-Morph), was characterized using spectroscopic techniques including FT-IR and H NMR. Vibrational frequencies obtained from FT-IR and proton NMR (H) chemical shifts were accurately predicted employing the density functional theory (DFT) at the B3LYP level of theory.

An innovative strategy for deworming dogs in Mediterranean areas highly endemic for cystic echinococcosis.

Background: Cystic echinococcosis (CE), caused by the larval stage of Echinococcus granulosus sensu lato, is a zoonotic parasitic disease of economic and public health importance worldwide, especially in the Mediterranean area. Canids are the main definitive hosts of the adult cestode contaminating the environment with parasite eggs released with feces. In rural and peri-urban areas, the risk of transmission to livestock as well as humans is high because of the free-roaming behavior of owned/not owned dogs.

High-Molecular-Weight Xylanase from B. pumilus US570 Strain: Purification, Characterization and Application in Banana and Orange Peels Hydrolysis and Breadmaking.

New xylanase (XylUS570) was purified from the Bacillus pumilus US570 strain. It has a molecular mass of about 232 kDa. This is the first report on the highest molecular weight monomeric xylanase produced by bacteria.

Serological screening for celiac disease, by endomysial antibodies, in patients with rheumatoid arthritis.

Celiac disease (CD) and rheumathoid arthritis (RA) are both multi-factorial chronic inflammatory auto-immune diseases. In this retrospective study, we determined the frequency of CD in patients with RA using IgA anti-endomysial antibodies (EmA) and tried to explain this association. Indirect immunofluorescence on human umbilical cord was used to detect EmA in 215 patients with seropositive RA collected over a 4-year-period.

Colorectal anticancer activity of a novel class of triazolic triarylmethane derivatives.

Triarylmethanes and triazoles constitute privileged structures extensively used in drug discovery programs. In this work, 12 novel triarylmethanes linked to a triazole ring were designed, synthesized, and chemically characterized aiming to target colorectal cancer. The synthetic strategy for triarylmethanes mono- and bi-substituted by a functionalized triazole ring involved a 1,3-dipolar cycloaddition.

Middle lobe syndrome revealing Broncholithiasis: A Case Report.

Middle lobe syndrome is a rare but important clinical entity worth investigating in local obstructive or inflammatory cause. One of its rare etiologies is broncholithiasis. We report the observation of a young female patient who presented with recurrent hemoptysis.

[Implementation of an Advanced Planning and Scheduling System in a pharmaceutical context].

Optimizing its supply chain has now become more than a necessity for any company seeking to expand its national and international market, so that it is able to continue its progress and fulfil its obligations towards its employees and its customers, particularly in the pharmaceutical context. The Covid-19 pandemic has shown the importance of resilience in the pharmaceutical industry to deal with unexpected disruptions and high demand from patients and authorities. Better production planning based on data management and predictive analysis, through the use of new Industry 4.

Quantum cluster equilibrium theory applied to liquid ammonia.

Through this paper, the authors propose using the quantum cluster equilibrium (QCE) theory to reinvestigate ammonia clusters in the liquid phase. The ammonia clusters from size monomer to hexadecamer were considered to simulate the liquid ammonia in this approach. The clusterset used to model the liquid ammonia is an ensemble of different structures of ammonia clusters.

[Reversed polarity high-cell carcinoma of the breast: A case report].

Reverse polarity high-cell carcinoma of the breast, formerly known as reverse polarity solid papillary carcinoma, is a rare entity recently introduced into the latest edition of the WHO classification of breast tumors. Its phenotype is triple-negative, and its diagnosis difficult. Although few cases have been reported in the literature, knowledge of this breast tumor is essential to distinguish it from other triple-negative carcinomas, which have a poorer prognosis.

[Elderly onset Crohn's disease: Clinical and therapeutic features].

Crohn's disease (CD) is a pathology that typically affects young people. With the aging of the population, there is an increase of its incidence in the elderly. Several studies have compared the clinical and therapeutic features of the CD in the elderly and young patients with discordant results.

Immunohistochemical analysis of myeloperoxidase expression in cutaneous leucocytoclastic vasculitis.

Myeloperoxidase (MPO) is a pro-oxidant enzyme mainly found in the azurophilic granules of neutrophils. It not only displays a key role in the intracellular microbial killing process but also contributes to the extracellular clearance of several pathogens. This study aimed to detect MPO in cutaneous leukocytoclastic vasculitis (LCV) using immunohistochemistry.
