The Cape harvester ant,Messor capensis (Mayr), is widespread in the more arid regions of southern Africa, where it forms trails many meters long and harvests considerable quantities of seeds. The poison gland contains primarily the alkaloid, anabaseine, with minor amounts of the related alkaloid, anabasine, and an unidentified compound. The Dufour's gland contains predominantly alkanes and alkenes of carbon chain length 12-23.n-Pentadecane is the major component, with lesser amounts ofn-pentadecene,n-tridecane,n-heptadecane,n-tetradecane,n-heneicosene, andn-tricosene. The dienes,n-heneicosadiene andn-tricosadiene are rather unusual components of the Dufour's gland of ants.

Usefulness of differential somatic cell count for udder health monitoring: effect of intramammary infections, days in milk, quarter location, and parity on quarter-level differential somatic cell count and somatic cell score in apparently healthy dairy cows.

Microbial infections of the mammary gland often cause mastitis, and it can lead to substantial economic losses within the dairy industry due to its direct negative impact on milk production and composition and the associated treatment costs. Somatic cell count has emerged as a critical indicator in monitoring udder health, and recently, the large-scale availability of differential cell count analysis potentially offers new insights into underlying physiological processes. Therefore, the main objective of this study was to estimate the variation of DSCC and SCC of individual quarter-level milk samples of cows according to 1) their intramammary infectious status; 2) parity of the cow; 3) quarter location; and 4) DIM at the time of sampling.

Variation in species distribution and diversity of staphylococci and mammaliicocci (SaM) causing intramammary infections in dairy cattle is associated with different management practices. Disparate selective pressures on organic dairies could potentially result in population differences of these mastitis-causing bacteria. The species-specific effect on quarter SCC of SaM for a population of certified organic dairies has not been described previously.

Introduction: Salivary carcinomas of the tongue represent a therapeutic challenge as their radical excision is particularly mutilating. We aimed to study the oncologic and functional outcomes of advanced stages salivary carcinomas of the tongue.
Materials And Methods: This retrospective multicentric study, based on the French national network on rare head and neck cancers (REFCOR), included all patients with a T3-T4 salivary carcinoma of the tongue, diagnosed between January 2009 and December 2018.

Article Synopsis
- Pheromone communication is crucial for maintaining reproductive roles in insect communities, but the molecular details of pheromone production are still not well understood.
- Bumble bees are a valuable model for studying pheromone biosynthesis because their worker bees produce unique ester signals that are distinct from those produced by queens and gynes.
- Research indicates that the regulation of pheromone production in bumble bee workers occurs at the protein level rather than at the gene expression level, suggesting different mechanisms for regulating pheromone synthesis among the different castes (workers, gynes, and queens).
