Human perinatal hypoxic-ischemic brain injury is an important cause of death and morbidity. One relatively common pattern of perinatal injury involves selective neuronal death in the ventral gray matter of the pons and in the subiculum of the hippocampal formation, classically termed 'pontosubicular neuronal necrosis' (PSN). The vulnerable neurons undergo(More)
The majority of postmenopausal breast cancers are estrogen-dependent. Tumor-derived factors, such as prostaglandin E2 (PGE2), stimulate CREB1 binding to cAMP response elements (CREs) on aromatase promoter II (PII), leading to the increased expression of aromatase and biosynthesis of estrogens within human breast adipose stromal cells (ASCs). Hypoxia(More)
The objective of this study was to evaluate the effectiveness of BPTB autografts versus HT autografts at a minimum of 5 years after anterior cruciate ligament (ACL) reconstruction. A systematical search of literature was performed in PubMed, Embase and the Cochrane library to identify published randomized controlled trials (RCT) or prospective cohort(More)
Phase III aromatase inhibitors (AIs) are proving successful in the treatment of hormone-dependent postmenopausal breast cancer. Side-effects associated with total body aromatase inhibition have prompted new research into the development of breast-specific AIs. The identification of tissue- and disease-specific usage of aromatase promoters has made the(More)
The classical axis of renin-angiotensin system (RAS), angiotensin (Ang)-converting enzyme (ACE)/Ang II/AT1, contributes to the development of non-alcoholic fatty liver disease (NAFLD). However, the role of bypass axis of RAS (Angiotensin-converting enzyme 2 (ACE2)/Ang-(1-7)/Mas) in hepatic steatosis is still unclear. Here we showed that deletion of ACE2(More)
Aromatase converts androgens into estrogens and its expression within adipose stromal cells (ASCs) is believed to be the major driver of estrogen-dependent cancers in older women. Ghrelin is a gut-hormone that is involved in the regulation of appetite and known to bind to and activate the cognate ghrelin receptor, GHSR1a. The unacylated form of ghrelin,(More)
OBJECTIVE To compare the effects of different approaches to establishing rat models of acute liver failure (ALF). METHODS Sixty-eight Sprague-Dawley rats were randomly divided into 3 groups for establishing ALF models using 3 different approaches, namely conventional hepatectomy for resecting 90% liver tissue as described by Higgins and Anderson, modified(More)
We previously showed the non-steroidal anti-inflammatory drug (NSAID) ibuprofen suppresses inflammation and amyloid in the APPsw (Tg2576) Tg2576 transgenic mouse. The mechanism for these effects and the impact on behavior are unknown. We now show ibuprofen’s effects were not mediated by alterations in amyloid precursor protein (APP) expression or oxidative(More)
Background The risk of breast cancer in postmenopausal women is increased two-fold with obesity, and the majority of breast tumours that arise are oestrogen-dependent. After menopause, when the ovaries cease to produce oestrogens, it is the local production of oestrogens within the breast adipose stromal cells (ASCs) which promotes and sustains tumour(More)
OBJECTIVE To investigate diagnosis and surgical management of femoral head osteonecrosis in sickle cell disease (SCD). METHODS The related literature available today was reviewed, and the clinical advance in the diagnosis of femoral head osteonecrosis complicating SCD and its surgical management was evaluated. RESULTS Although the advance in the(More)
