background: poisoning is a serious health problem in the world. in the intentional type, the person may attempt suicide by self-poisoning or may be poisoned by others in a criminal act. the present study was designed to investigate the causes and the frequency of poisoning cases referring to loqman hospital, tehran, iran, during summer 2010. methods: in this descriptive-analytical study, age, g...

[figure: see text] A tandem anionic 5-exo-dig cyclization/Claisen rearrangement sequence was used to effect a facile, "one-pot" conversion of an appropriately substituted 4-alkyn-1-ol to the tetracyclic carbon core structure of phorbol. The synthesis was conducted using readily available nonracemic starting materials to provide the target structure as a single enantiomer in high chemical yield.

objective: depression is a major health problem, which is not only underrecognized and undertreated, but is also associated with significant morbidity and mortality. it has been suggested that combination therapy rapidly reduces depressive symptoms in patients with moderate to severe depression and is more effective than monotherapy; but this suggestion remains controversial. serotonergic and n...

general population surveys often report that only a small proportion of individuals with common mental disorders seek mental health treatment, suggesting a high level of unmet need for mental health care in the community. in recent years, however, the number of adults in industrialized countries who are treated with antidepressant medications has dramatically increased. this paper reviews the p...

A study of the chemical constituents from the Australian Sponge Hyrtios digitatus has provided a perspective on the connection between the chemistry and biology of the puupehenones, a unique and unusual class of merosesquiterpenes. In this study, a new tetracyclic merosesquiterpene, 19-methoxy-9,15-ene-puupehenol (1) was isolated from the marine sponge Hyrtios digitatus along with the known 20-...

The novel 3H-spiro[1-benzofuran-2-cyclopentan]-3-one skeleton has been made accessible by different routes. One- and two-step protocols lead to tricyclic and tetracyclic benzofuranones 2 and 3, respectively. A four-step synthesis to spirocompound 4 is described. The novel spirocyclic benzofuranones display modest to no inhibition of the human peptidyl prolyl cis/trans isomerase Pin1.

  Background: It has been suggested, although not proven, that presence of concomitant psychiatric disorders may increase the inpatient costs for patients undergoing elective surgery. This study was designed to test the hypothesis that elective lumbar fusion surgery is more costly in patients with under treatment for depression. Methods: This is a retrospective case-control study of 142 patient...

Aiming at restricting the conformational freedom of tryptophan-containing peptide ligands, we designed a THBC (tetrahydro-β-carboline)-DKP (diketopiperazine)-based peptidomimetic scaffold capable of arranging in an unusual α-turn conformation. The synthesis is based on a diastereoselective Pictet-Spengler condensation to give the THBC core, followed by an intramolecular lactamization to complet...

mirtazapine is a new antidepressant that can increase noradrenergic and serotonergic neurotransmission. it is also a postsynaptic antagonist of 5-ht2 and 5-ht3. in addition, it has only a weak affinity for 5-ht1 receptors and has very weak muscarinic anticholinergic and histamine (h1) antagonist properties. we report a case of hypertensive urgency that ensued after a patient took a single low d...

introduction: celastrus paniculatus seed oil, commonly known as malkangni or jyotishmati, was in use from time immemorial to treat brain related disorders. celastrus paniculatus seed oil has significant antidepressant-like activity in chronic unpredictable stressed mice. the present study was undertaken to evaluate the antidepressant-like effect of celastrus paniculatus seed oil in unstressed m...
