BACKGROUND For meshes to be used effectively for hernia repair, it is imperative that engineers and surgeons standardize the terminology and techniques related to physicomechanical evaluation of these materials. The objectives of this study were to propose standard techniques, perform physicomechanical testing, and classify materials commonly used for(More)
BACKGROUND This study aimed to compare the physicomechanical properties of composite prostheses for laparoscopic ventral hernia repair (LVHR) through standard testing and a proposed classification system. METHODS Seven prostheses (four with absorbable barriers and 3 with nonabsorbable barriers) were evaluated. The barrier layer was removed, after which(More)
BACKGROUND Corpus luteum (CL) regression is known to occur as two parts; functional regression when steroidogenesis declines and structural regression when apoptosis is induced. Previous studies suggest this process occurs by the production of luteolytic factors, such as tumour necrosis factor-alpha (TNF-alpha). METHODS We examined TNF-alpha, TNF-alpha(More)
Approximately 1-2% of colorectal cancers (CRC) arise because of germline mutations in DNA mismatch repair genes, referred to as Lynch syndrome. These tumours show microsatellite instability (MSI) and loss of expression of mismatch repair proteins. Pre-symptomatic identification of mutation carriers has been demonstrated to improve survival; however, there(More)
Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant cancer syndrome characterized by early age of onset colorectal cancer (mean 45 years) as well as endometrial, urinary tract, and upper gastrointestinal adenocarcinomas. The HNPCC phenotype has been shown to segregate with germline mutations in the human homologues of the DNA mismatch(More)
INTRODUCTION Laparoscopic adrenalectomy (LA) is the standard for removal of adrenal pheochromocytomas (pheos), but laparoscopic (LAP) resection of paragangliomas (PGs) is controversial. This study analyzes our results of resection of PGs in the LAP era. METHODS A retrospective record review of all patients who underwent resection of intra-abdominal PGs(More)
We have examined the histological and ultrastructural features of CNS infection with Murray Valley encephalitis (MVE) virus in mice inoculated with a virulent parental strain (BH3479). Light microscopic examination revealed neuronal necrosis in the olfactory bulb and hippocampus of MVE-infected brains by 5 days post-infection (pi). Electron microscopy of(More)
Protein microarrays combine aspects of DNA microarrays and ELISA for the parallel interrogation of a biological sample using a multiplex of protein biomarkers. Here we report the development of a protein microarray consisting of a subset of CD antibodies and CRP. Several preparations (culture supernatant, ascites fluid and purified Ig) of each antibody were(More)
Tumor necrosis factor-alpha (TNFalpha) is a pleiotropic cytokine that has been implicated in apoptosis of many cell systems. However, the signal transduction of TNFalpha during the structural and functional regression of the corpus luteum (CL) is largely unknown. In this study, we investigate the role of TNFalpha in rat CL apoptosis and the involvement of(More)
