Thyroxin Is Useful to Improve Sperm Motility

Objective The aim of this study was to evaluate the non-genomic action of thyroxin on sperm kinetic and its probable use to improve sperm recovery after applying an enrichment method like “swim-up” in comparison with the available one, pentoxifylline. MaterialsAndMethods This is an experimental study. A total of 50 patients were recruited, followed by infertility consultation. Conventional sper...

Is overall similarity classification less effortful than single-dimension classification?

It is sometimes argued that the implementation of an overall similarity classification is less effortful than the implementation of a single-dimension classification. In the current article, we argue that the evidence securely in support of this view is limited, and report additional evidence in support of the opposite proposition--overall similarity classification is more effortful than single...

Preoperative Upper Endoscopy is Useful Before Revisional Bariatric Surgery

BACKGROUND AND OBJECTIVES We hypothesized that patients who have previously had bariatric surgery and are undergoing revision to laparoscopic Roux-en-Y gastric bypass would have abnormal findings detected by upper endoscopy that could potentially influence patient management. The procedures that are being revised include vertical banded gastroplasty, laparoscopic adjustable gastric bands, nonad...

ABC-LogitBoost for Multi-class Classification

We develop abc-logitboost, based on the prior work on abc-boost[10] and robust logitboost[11]. Our extensive experiments on a variety of datasets demonstrate the considerable improvement of abc-logitboost over logitboost and abc-mart.
