Acute cerebellitis is a rare inflammatory disease involving the cerebellum and is characterized by acute compromise of cerebellar functions. It most frequently originates from infectious causes, although cases of cerebellitis associated with other causes have also been reported. This report discusses a case of cerebellitis developing in a 4-year-old girl who had to be intubated after accidental...
Highly enantioselective access to cannabinoid-type tricyles by organocatalytic Diels–Alder reactions
After prosperous domino reactions towards benzopyrans, the products were used as the starting material in Lewis acid catalyzed and organocatalytic Diels-Alder reactions to build up a tricyclic system. Herein, an asymmetric induction up to 96% enantiomeric excess was obtained by the use of imidazolidinone catalysts. This approach can be utilized to construct the tricyclic system in numerous natu...
Tricyclic lactam model compounds of the left half (ABC ring) of renieramycin and saframycin anticancer natural products were prepared from common intermediate 6a. Readily available alcohol 6a was converted into enamide 8, and this was followed by transformation into 6b through a hydrobromination reaction in a stereoselective manner. Some diastereomers at C-6 to C-11a of the tricyclic lactam mod...
Major depressionis one of the most commonclinicalproblemsseen by primary-carephysicians.The prevalenceis 5% to 10% in primary-careoutpatientsand 15% in medicallyill inpatients. Despite this high prevalence rate, depression is frequently not accurately diagnosed. Evidence suggests that misdiagnosis often occurs because patients with depression frequently focus preferentially on somatic complaint...
