Acute alcohol intoxication presenting acquired lesion of the corpus callosum in a young healthy woman: A case of possible Marchiafava-Bignami disease.

Background: Marchiafava-Bignami disease is a rare neurological disease characterized by acquired lesions of the corpus callosum. Although the major causative etiology is chronic alcoholism, a case caused by acute alcohol intoxication has not yet been reported.

Case Presentation: A 19-year-old female with no known medical history or a history of chronic alcohol consumption was brought to the emergency department in a coma after binge alcohol consumption.

Identification and characterization of ferulic acid esterase from Penicillium chrysogenum 31B: de-esterification of ferulic acid decorated with l-arabinofuranoses and d-galactopyranoses in sugar beet pectin.

We previously described the fungus Penicillium chrysogenum 31B, which has high performance to produce the ferulic acid esterase (FAE) for de-esterifying ferulic acids (FAs) from sugar beet pulp. However, the characteristics of this fungus have not yet been determined. Therefore, in this study, we evaluated the molecular characteristics and natural substrate specificity of the Pcfae1 gene from Penicillium chrysogenum and examined its synergistic effects on sugar beet pectin.

An objective approach using three indexes for determining fatal hypothermia due to cold exposure; statistical analysis of oxyhemoglobin saturation data.

Analysis of oxyhemoglobin (O2-Hb) saturation levels in the left and right heart blood is useful in the assessment of exposure to cold surroundings before death. We quantified conventional subjective visual evaluation of O2-Hb saturation levels and developed useful diagnostic criteria for fatal hypothermia: O2-Hb saturation in the left heart blood (L-O2Hb) was ⩾36%, the O2-Hb saturation gap between the left and right heart blood (L-R gap) was ⩾13%, and the O2-Hb saturation ratio of the left to right heart blood (L/R ratio) was ⩾1.8.

Biochemical characterization of a GH53 endo-β-1,4-galactanase and a GH35 exo-β-1,4-galactanase from Penicillium chrysogenum.

An endo-β-1,4-galactanase (PcGAL1) and an exo-β-1,4-galactanase (PcGALX35C) were purified from the culture filtrate of Penicillium chrysogenum 31B. Pcgal1 and Pcgalx35C cDNAs encoding PcGAL1 and PcGALX35C were isolated by in vitro cloning. The deduced amino acid sequences of PcGAL1 and PcGALX35C are highly similar to a putative endo-β-1,4-galactanase of Aspergillus terreus (70% amino acid identity) and a putative β-galactosidase of Neosartorya fischeri (72%), respectively.
