Rhodium complexes of diazaphospholane ligands catalyze the asymmetric hydroformylation of N-vinyl carboxamides, allyl ethers, and allyl carbamates; products include 1,2- and 1,3-aminoaldehydes and 1,3-alkoxyaldehydes. Using glass pressure bottles, short reaction times (generally less than 6 h), and low catalyst loading (commonly 0.5 mol %), 20 substrates are successfully converted to chiral ald...

Background: The effects of magnesium physiology are contradictory to the neurotoxic effect of bilirubin, but the relationship between magnesium level and hyperbilirubinemia in neonates has not been well studied. In this study, we investigated the relationship between serum magnesium level and hyperbilirubinemia and hyperbilirubinemia complications at the Children’s Medical Center. Methods: In ...

In this paper we present a model for the short (< second) population of gamma-ray bursts (GRBs). In this model heated neutron stars in a close binary system near their last stable orbit emit neutrinos at large luminosities (∼ 1053 ergs/sec). A fraction of these neutrinos will annihilate to form an ee pair plasma wind which will, in turn, expand and recombine to photons which make the gamma-ray ...

Addition of lithium aryl(tetraisopropoxy)titanates [ArTi(OPri)4 Li ] to , -unsaturated ketones proceeded with high enantioselectivity (up to 99% ee) in the presence of an excess amount of chlorotrimethylsilane and a rhodium catalyst (3 mol % Rh), generated from [RhCl(C2H4)2]2 and (S)-binap, in tetrahydrofuran at 20°C to give high yields of the corresponding silyl enolates as 1,4-addition produc...

acute necrotizing encephalopathy of childhood (anec) is a specific type of encephalopathy. after viral infection, it  can be diagnosed by bilateral symmetrical lesions that are predominantly observed in thalami & brainstem of infants & children. although, it is commonly occurred in japanese and taiwanese population. the goal of this article is to report a rare case of anec in  north part of ira...

BACKGROUND/AIMS Hashimoto's encephalopathy is considered as a treatable dementia, but it is often misdiagnosed. We investigated cognitive impairment and the MRI pathology of Hashimoto's encephalopathy patients. METHODS The study comprised eight patients with Hashimoto's encephalopathy, 16 patients with mild Alzheimer's disease and 24 healthy subjects. A neuropsychological battery included ass...

INTRODUCTION Minimal hepatic encephalopathy refers to a mild neurocognitive impairment not detectable by clinical examination that can be present in cirrhotic patients. AIM To determine the prevalence of minimal hepatic encephalopathy in a secondary healthcare center in Northern Portugal. MATERIAL AND METHODS A cross-sectional study was conducted. Cirrhotic outpatients were included. EXCL...

64 Hepatic encephalopathy (HE) or Portosystemic encephalopathy (PSE) in end-stage liver disease (ESLD) such as cirrhosis of the liver is a reversible and recurrent disorder of neurological function caused by liver disease or portosystemic shunting of blood or both. In this article only hepatic encephalopathy (HE) in chronic end-stage liver disease (ESLD) will be discussed. Hepatic encephalopath...

background: some evidence has shown benefits of probiotics in the management of minimal hepatic encephalopathy (mhe). we evaluated the efficacy of a multistrain probiotic compound, alone and in combination with lactulose, in the treatment of mhe. materials and methods: h   is study has two parts. first, consecutive adult patients with mhe were randomized to receive lactulose (30–60 ml/day) + pr...
