OBJECTIVE Formaldehyde is still widely employed as a universal crosslinking agent, preservative and disinfectant, despite its proven carcinogenicity in occupationally exposed workers. Therefore, it is of paramount importance to understand the possible impact of low-dose formaldehyde exposures in the general population. Due to the concomitant occurrence of multiple indoor and outdoor toxicants, ...

introduction: adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. this in vitro study evaluated the sealing ability of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement and biodentine in repair of furcation perforation in primary molars. methods and materials: a total of 61 freshly extracted primary ma...

Objectives: Laparoscopic inguinal hernia repair has been promoted as having significant advantages. The aim of this study is to evaluate the early results of total extra peritoneal laparoscopic inguinal hernia repair at the Royal Medical Services hospitals of Jordan Armed Forces. Methods: During the period between April 2004 to May 2006, 100 patients underwent total extra peritoneal laparoscopi...

The ultimate measure of success of inguinal hernia repair is the rate of recurrence. Although other procedure-related complications are important and have been shown to affect healthrelated quality-of-life parameters, recurrence is more challenging for the patients and the surgeon. From the patients’ perspective, the initial physical and mental investment in the operation has failed. A new inve...

Repair is a central component of circular economy to extend the operational phase products. Yet, number repair service providers as well demand for have declined over last decades, while more products than ever before were sold. Thus, successful transition from linear services must be boosted promote business. A starting point achieve this goal increase knowledge about end consumers’ intention ...

background: in the past three decades, tehran has experienced warmer summer so we need to determine heat-related mortality to establish appropriate public health activities during hot summers. the aim of the present study was to detect heat waves during the last decades and then determine excess mortality in immediate and lagged times. method: an ecological study based on time-series model was ...

This paper deals with the transient analysis of batch arrival retrial queueing system with general retrial times, priority service, balking, second optional service, Bernoulli vacation, extended vacation, breakdown, delayed repair and stand by server. Here we assume that customers arrive in batches according to compound Poisson processes, where the blocked customers either with probability p jo...

conclusions clonidine plus bupivacaine can increase the duration of motor and sensory block in arthroscopic cruciate ligament repair under spinal anesthesia. however, due to significant hemodynamic changes, further studies are required to determine a safer dose. results all patients were males with a mean age of 24.9 years in group b, and 25.2 years in group bc (p > 0.05). in group bc, time lap...

HYPOTHESIS The use of laryngeal mask airway and propofol in inguinal hernia repair results in shorter operative and recovery room times. DESIGN Randomized control trial. SETTING University hospital. PATIENTS From May 2000 to March 2002, a convenience sample of 79 patients was invited to participate; 34 entered the study. Fifteen patients were randomized to subarachnoid block, and 18 patie...

BACKGROUND Inguinal herniorrhaphy remains one of the most common general surgical operations, with approximately 15% performed for recurrence. The repair of the resulting recurrent hernia is a daunting task because of already weakened tissues and obscured and distorted anatomy. The aim of this study is to compare the posterior preperitoneal versus anterior tension-free approach for repair of un...
