Iron regulatory protein 1 (IRP1) is a cytosolic bifunctional [4Fe-4S] protein which exhibits aconitase activity or binds iron responsive elements (IREs) in untranslated regions of specific mRNA encoding proteins involved in cellular iron metabolism. Superoxide radical (O2.-) converts IRP1 from a [4Fe-4S] aconitase to a [3Fe-4S] "null" form possessing neither aconitase nor trans-regulatory activity. Genetic ablation of superoxide dismutase 1 (SOD1), an antioxidant enzyme that acts to reduce O2.- concentration, revealed a new O2...

In liver transplant (LT) recipients, the cause of graft dysfunction in pregnancy is often difficult to ascertain. Moreover, a liver biopsy in late pregnancy is often avoided as a consequence of patient and physician factors. Management of graft dysfunction can be difficult in this setting. We report a 30-year-old female LT recipient who developed acutely deranged liver biochemistry during the third trimester of her first pregnancy. At 29 weeks gestation, her liver function test (LFT) became abnormal; AST peaked at 978 IU/L (normal range 10-50), GGT 25 IU/L (normal range 1-55), bilirubin 1...

BACKGROUND: Graft-derived cell-free DNA (GcfDNA), which is released into the blood stream by necrotic and apoptotic cells, is a promising noninvasive organ integrity biomarker. In liver transplantation (LTx), neither conventional liver function tests (LTFs) nor immunosuppressive drug monitoring are very effective for rejection monitoring. We therefore hypothesized that the quantitative measurement of donor-derived cell-free DNA (cfDNA) would have independent value for the assessment of graft integrity, including damage from acute rejection...

Food availability significantly affects an animal's energy metabolism, and thus its phenotype, survival, and reproduction. Maternal and offspring responses to food conditions are critical for understanding population dynamics and life-history evolution of a species. In this study, we conducted food manipulation experiments in field enclosures to identify the effect of food restriction on female reproductive traits and postpartum body condition, as well as on hatchling phenotypes, in a lacertid viviparous lizard from the Inner Mongolian desert steppe of China...

BACKGROUND: Children born with esophageal atresia require an anastomosis between the proximal and distal esophagus. When this distance is too wide (long gap esophageal atresia, LGEA) esophageal replacement strategies have to be deployed. The aim of this study was to assess long-term respiratory morbidity and lung function after esophageal replacement with either stomach (gastric pull-up, GPU) or jejunum (jejunal interposition, JI) for LGEA. METHODS: Retrospective cohort study...

BACKGROUND: Hypertrophy of the ligamentum flavum (LF) has been considered as a major cause of lumbar central spinal stenosis (LCSS). Previous studies have found that ligamentum flavum thickness (LFT) is correlated with aging, disc degeneration, and lumbar spinal stenosis. However, hypertrophy is different from thickness. Thus, to evaluate hypertrophy of the whole LF, we devised a new morphological parameter, called the ligamentum flavum area (LFA). OBJECTIVES: We hypothesized that the LFA is a key morphologic parameter in the diagnosis of LCSS...

An exact mapping is established between the c≥25 Liouville field theory (LFT) and the Gibbs measure statistics of a thermal particle in a 2D Gaussian free field plus a logarithmic confining potential. The probability distribution of the position of the minimum of the energy landscape is obtained exactly by combining the conformal bootstrap and one-step replica symmetry-breaking methods. Operator product expansions in the LFT allow us to unveil novel universal behaviors of the log-correlated random energy class...

BACKGROUND: Current liver function testing for statin monitoring is largely unnecessary and costly. Statins do not cause liver disease. Both reduction in test frequency and use of a single alanine transaminase (ALT) rather than a full seven analyte liver function test (LFT) array would reduce cost and may benefit patients. AIM: To assess LFT testing in relation to statin use and evaluate an intervention to reduce full-array LFTs ordered by GPs for statin monitoring...

INTRODUCTION: Eighty percent of all UK elective laparoscopic cholecystectomies (LC) are performed as day-case procedures, but the pre-operative patient pathway has received little attention. In response to local patient feedback, we aimed to introduce a single hospital visit pathway for day-case LC. METHODS: A single hospital visit pathway for elective LC was piloted alongside standard services. Following telephone consultation, a pack containing procedure information, knowledge questionnaire and consent form were sent...
