Genetic Analysis of Days Open in Moroccan Holstein Using Different Models to Account for Censored Data.

Reproductive efficiency is a key element of profitability in dairy herds. However, the genetic evaluation of fertility traits is often challenged by the presence of high censorship rates due to various reasons. An easy approach to address this challenge is to remove the censored data from the dataset.

Integrating proteomics and metabolomics to evaluate impact of semen collection techniques on the quality and cryotolerance of goat semen.

Results of artificial insemination (AI) are affected by changes in sperm quality and the function throughout collection and preservation procedures. Proteome and metabolome alterations of sperm treated with the different procedures in goat, however, aren't fully understood. To this end, we sought to investigate the impacts of rectal probe electrostimulation (EE) and artificial vagina (AV) semen collection methods on the quality and the cryotolerance of goat sperm, with additional focus on proteomic and metabolomic analyses.

CXCL8 secreted by immature granulocytes inhibits WT hematopoiesis in chronic myelomonocytic leukemia.

Chronic myelomonocytic leukemia (CMML) is a severe myeloid malignancy with limited therapeutic options. Single-cell analysis of clonal architecture demonstrates early clonal dominance with few residual WT hematopoietic stem cells. Circulating myeloid cells of the leukemic clone and the cytokines they produce generate a deleterious inflammatory climate.

Environmental determinants of venom variability in captive scorpions: A comprehensive analysis of diet, temperature, and humidity effects.

This study examines the effects of environmental conditions on venom production in four prevalent scorpion species in Morocco: Androctonus amoreuxi, Androctonus mauretanicus, Buthus mardochei, and Scorpio maurus. The research focuses on how climatic factors such as temperature, humidity, and diet-specifically mealworm consumption-affect physical parameters including size and weight, and ultimately venom yield. We conducted a comprehensive investigation involving the capture, acclimatization, and systematic venom extraction from 480 scorpions.
