A simplified courtship conditioning protocol to test learning and memory in Drosophila.

In Drosophila, a male that has previously been sexually rejected reduces its courtship behavior when confronted again with an unreceptive female. This reduced courting time reflects a memory formation process. Here, we describe a simplified protocol to perform the courtship conditioning assay for assessing the reduced courting time, using regular lab equipment and handmade tools.

Psychological and Personality Predictors of Weight Loss and Comorbid Metabolic Changes After Bariatric Surgery.

Bariatric surgery (BS) has proven to be the most effective treatment for weight loss and for improving comorbidities in severe obesity. A comprehensive psychological assessment prior to surgery is proposed to prepare patients for a successful post-surgical outcome. Therefore, the main aim of the present study was to assess psychological and personality predictors of BS outcome.

Full HPV typing by a single restriction enzyme.

Background: Restriction fragment length polymorphism (RFLP) methods for genotyping genital human papillomavirus (HPV) are considered labor consuming and constrained by the reduced set of restriction enzymes capable of detecting specific mutations. However, we think that these methods have not taken full advantage of the high diversity of the known restriction enzymes.

Objective: We have set out to find the best restriction enzyme for HPV typing.
