Evolution of queen pheromone receptor tuning in four honeybee species (Hymenoptera, Apidae, Apis).

Honeybees (genus: Apis) use a plethora of pheromones for intraspecific communication. The primary compound produced by the queen's mandibular glands, 9-ODA, is involved in mating in all Apis species. It is the ligand of the most highly expressed olfactory receptor in males of : OR11.

Combined radiographic and ultrasound evaluations to decipher joint involvement in the hands of patients with systemic sclerosis.

Objective: The objective of this study was to explore the etiologies and contributing factors of synovial and tenosynovial involvement in SSc, as well as to assess the phenotype of patients with these synovial and tenosynovial features.

Methods: 171 SSc patients with hand manifestations (either vascular, skin or joint manifestations) who underwent standard X-rays of both hands and hand ultrasound (US), were included. Two independent evaluators recorded the presence or absence of acro-osteolysis, calcinosis, microcrystalline and degenerative rheumatisms, including osteophytosis on X-Rays.

Effect of dietary methionine to crude protein ratio on performance of Ross 308 broiler chickens aged 22 to 42 days.

An experiment was conducted to determine the effect of dietary methionine to crude protein (CP) ratio on the performance of male Ross 308 broiler chickens aged 22 to 42 days. The diets were isocaloric and isonitrogenous but with different methionine-to-CP ratios. The diets, based on methionine to crude protein ratios, were M (0.

Identification of CT radiomic features robust to acquisition and segmentation variations for improved prediction of radiotherapy-treated lung cancer patient recurrence.

The primary objective of the present study was to identify a subset of radiomic features extracted from primary tumor imaged by computed tomography of early-stage non-small cell lung cancer patients, which remain unaffected by variations in segmentation quality and in computed tomography image acquisition protocol. The robustness of these features to segmentation variations was assessed by analyzing the correlation of feature values extracted from lesion volumes delineated by two annotators. The robustness to variations in acquisition protocol was evaluated by examining the correlation of features extracted from high-dose and low-dose computed tomography scans, both of which were acquired for each patient as part of the stereotactic body radiotherapy planning process.
