OBJECTIVE The purpose of this study was to analyze bladder tumor (BT) associated with renal pelvic and/or ureteral tumor (RUT), with emphasis on the relationship between the grade and stage of these tumors. METHODS We reviewed 77 cases of RUT operated upon at our hospital during the last 14 years. We herein define stage T1b tumor as invasive since this stage of tumor is considered to have a d...

INTRODUCTION The purpose of the quality standards document is to provide healthcare professionals, commissioners, service providers and patients with a guide to standards of care that should be met for home oxygen provision in the UK, together with measurable markers of good practice. Quality statements are based on the British Thoracic Society (BTS) Guideline for Home Oxygen Use in Adults. M...

Department of Obstetrics and Gynaecology, Prince of Wales Hospital, Shatin, Hong Kong Pap smear screening is a multi-step process that involves recruitment of patients, taking smear, making and reading slides and issuing reports to alert clinicians to take appropriate action. In the last decade, innovative technologies including liquid base cytology, automated screening and human papilloma viru...

Introduction These guidelines have been developed at the request of the Standards of Care Committee of the British Thoracic Society (BTS). Two particular problems have emerged since the previous BTS guidelines were published. 2 Firstly, there have been many cases reported recently of atypical mycobacteria causing contamination of bronchoscopes leading to pseudoinfections. Secondly, toxicity fro...

Sexually dimorphic breeding tubercles (BTs) are keratinized epidermal structures that form clusters on the dorsal surface of the anterior rays of zebrafish male pectoral fins. BTs appear during sexual maturation and are maintained through regular shedding and renewal of the keratinized surface. Following pectoral fin amputation, BT clusters regenerate after the initiation of revascularization, ...

The present paper looks for kinematic similarities between whole-body and arm movements executed in the sagittal plane. Eight subjects performed sit-to-stand (STS) and back-to-sit (BTS) movements at their preferred speed in the sagittal plane. Kinematics analysis focused on shoulder motion revealed that STS was composed of a straight, forward displacement followed by a curved, upward displaceme...

Introduction Peripheral microembolism is one of the most frequent causes of acute limb ischemia. In order to effectively prevent relapses it is essential to localize and eliminate the source of embolism. Aim To evaluate the role of Duplex Doppler ultrasound examination in identifying the causes of blue toe syndrome (BTS). Material and methods The group of 165 patients with clinical symptoms...

MTT (3-(4, 5-dimethyl thiazol-2-yl)-2, 5-diphenyl tetrazolium bromide) reduction assay is a method that validates the viability of an active cell. Dehydrogenase in mitochondria converts yellow colored insoluble tetrazolium salt to purple colored watersoluble formazan. Sperm also have mitochondria in the midpiece, therefore sperm viability could be evaluated by MTT reduction assay. Several studi...

PURPOSE Boston Terriers (BTs) have a greater prevalence of corneal endothelial dystrophy (CED), in comparison to other canine breeds. Similar to Fuchs' endothelial corneal dystrophy (FECD), this condition is characterized by endothelial cell degeneration with secondary corneal edema. This study assessed corneal morphology using in vivo confocal microscopy (IVCM) and Fourier-domain optical coher...

The anticorrosive agents 1H-benzotriazole (1H-BT), 4-methyl-1H-benzotriazole (4 Me-BT) and 5-methyl-1H-benzotriazole (5 Me-BT), which are usually added to dishwasher detergents, automotive antifreeze formulations and aircraft de-icing/anti-icing fluids (ADAFs), were measured in river water. Samples were collected from 15 sampling sites in the mainstream and selected tributaries of a medium-size...
