the aim of this paper is to study co-prolongations of central extensions. we construct the obstruction theory forco-prolongations and classify the equivalence classes of these by kernels of homomorphisms between 2-dimensional cohomology groups of groups.
sudden, unexpected death may occur in apparently healthy individuals. its occurrence in psychiatric patients has raised the concern that the use of psychotropics, especially antipsychotics, may be associated with an increased risk of sudden death. this concern is maintained even though not all psychiatric patients who have succumbed to sudden death have been on psychotropics. early reports pres...
dose-dependent effects of methadone on qt interval in patients under methadone maintenance treatment
background: the role of methadone in qtc prolongation, torsades de pointes (tdp) arrhythmia and sudden cardiac death has been debated. because of widespread use of methadone in methadone maintenance treatment (mmt) centers, we aimed to study dose-related effects of methadone on qtc prolongation. methods: in a comparative observational study, 90 patients who were under mmt were evaluated. patien...
background : methadone is considered as a good choice for maintenance treatment program (mmtp) in opioid addicted individuals. qt interval prolongation was reported previously in methadone chronic usersespecially in high dose prescription. qt-interval prolongation predisposes patients to lethal dysrhythmia. this is a report of corrected qt(qtc) prolongation due to acute methadone poisoning. to ...
cardiac involvement infrequently occurs in hypopituitarism, and lethal cardiac arrhythmias are rarely reported. we present a middle age female who died as a consequence of refractory ventricular arrhythmia whose medical history and previous laboratory investigation were consistent with hypopituitarism. we conclude that hypopituitarism may lead to electrocardiographic changes and malignant ventr...
the aim of this paper is to study the $(alpha, gamma)$-prolongation of central extensions. we obtain the obstruction theory for $(alpha, gamma)$-prolongations and classify $(alpha, gamma)$-prolongations thanks to low-dimensional cohomology groups of groups.
Although the epileptogenic properties of estrogens have been widely demonstrated in several models and species, the mechanism(s) by which estrogens can acutely change seizure parameters including after discharge and seizure duration remain remains to be determined. In the present study, we examined the role of NMDA (N-methyl-D-aspartate), non-NMDA and estrogenic receptors in estradiol benzoate ...
