Neonicotinoid pesticide use has increased around the world despite accumulating evidence of their potential detrimental sub-lethal effects on the behaviour and physiology of bees, and its contribution to the global decline in bee health. Whilst flower colour is considered as one of the most important signals for foraging honey bees (Apis mellifera), the effects of pesticides on colour vision and memory retention in a natural setting remain unknown. We trained free flying honey bee foragers by presenting artificial yellow flower feeder, to an unscented artificial flower patch with 6 different flower colours to investigate if sub-lethal levels of imidacloprid would disrupt the acquired association made between the yellow flower colour from the feeder and food reward.

Severe mitral regurgitation (MR) following surgical repair of the mitral valve poses a significant clinical challenge. Patients who have undergone surgery are typically at high risk for a second operation. This report details the case of a 54-year-old male who underwent aortic valve replacement and mitral valve repair using a 34-ring, 14 years prior.

IS ESG EFFECTIVE IN THE TREATMENT OF OBESITY AND ASSOCIATEDCOMORBIDITIES?: Endoscopic Sleeve Gastroplasty (ESG) is more effective than lifestyle modifications alone for weight loss and improving obesity-related comorbidities. While it has less effect on weight loss compared to Laparoscopic Sleeve Gastrectomy (LSG) in the short to medium term, it offers similar comorbidities resolution to LSG. IS ESG A SAFE PROCEDURE, AND WHAT ARE ITS RISKS?: The safety profile of ESG is consistently supported in the literature.

Ongoing efforts to improve sheep reference genome assemblies still leave many gaps and incomplete regions, resulting in a few common failures and errors in genomic studies. Here, we report a 2.85-Gb gap-free telomere-to-telomere genome of a ram (T2T-sheep1.
