Polynomial Solution of Non-Central Potentials

We show that the exact energy eigenvalues and eigenfunctions of the Schrodinger equation for charged particles moving in certain class of non-central potentials can be easily calculated analytically in a simple and elegant manner by using Nikiforov and Uvarov (NU) method. We discuss the generalized Coulomb and harmonic oscillator systems. We study the Hartmann Coulomb and the ring-shaped and compound Coulomb plus Aharanov-Bohm potentials as special cases. The results are in exact agreement with other methods.Comment: 18 page

The antioxidant activity of some curcuminoids and chalcones

The antioxidant properties of the synthetic compound (C1)–(C8), which comprised 7 curcuminoids and a chalcone, were evaluated by two complementary assays, DPPH and β-carotene/linoleic acid. It was found that, in general, the free radical scavenging ability of (C1)–(C8) was concentration-dependent. Compounds (C1) and (C4), which contained (4-OH) phenolic groups, were found to be highly potent antioxidants with higher antioxidant values than BHT suggesting that synthetic curcuminoids are more potent antioxidants than standard antioxidants like BHT. Using β-carotene-linoleic acid assay, only the water-soluble 2, 4,6-trihydroxyphenolic chalcone (C5) showed 85.2 % inhibition of the formation of conjugated dienes reflecting on its potent antioxidant activity

The role of open abdomen in non-trauma patient : WSES Consensus Paper

The open abdomen (OA) is defined as intentional decision to leave the fascial edges of the abdomen un-approximated after laparotomy (laparostomy). The abdominal contents are potentially exposed and therefore must be protected with a temporary coverage, which is referred to as temporal abdominal closure (TAC). OA use remains widely debated with many specific details deserving detailed assessment and clarification. To date, in patients with intra-abdominal emergencies, the OA has not been formally endorsed for routine utilization; although, utilization is seemingly increasing. Therefore, the World Society of Emergency Surgery (WSES), Abdominal Compartment Society (WSACS) and the Donegal Research Academy united a worldwide group of experts in an international consensus conference to review and thereafter propose the basis for evidence-directed utilization of OA management in non-trauma emergency surgery and critically ill patients. In addition to utilization recommendations, questions with insufficient evidence urgently requiring future study were identified.Peer reviewe

Antimicrobial and antioxidant activities of Pseudevernia furfuracea (L.) Zopf var. furfuracea and Evernia prunastri Lichens collected from Black Sea Region

The antimicrobial and antioxidant activities of the acetone extracts of lichen Pseudevernia furfuracea var. furfuracea (PF) and Evernia prunastri (EP) were investigated. Different antioxidant tests were applied such as ABTS (2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) radical scavenging activity and reducing power. Antimicrobial activities of lichen extracts were determined by agar well diffusion method and micro-well dilution assay. All lichen extracts exhibited antimicrobial activity against test bacteria. Antioxidant activity of PF extract is higher than EP extract. Acetone extracts of PF and EP could be considered as a source of natural antioxidant and antimicrobial agent

An unusual mesenteric paraganglioma producing human chorionic gonadotropin

Adrenal and extra-adrenal paragangliomas are uncommon neoplasms arising from the parenchymal cells of paraganglia. The presenting symptoms are mostly due to excess catecholamine secretion. Extra-adrenal paragangliomas are mostly localized in the superior para-aortic region of the abdomen. Mesenteric paragangliomas are very rare. We report an unusual case of mesenteric paraganglioma producing human chorionic gonadotropin (hCG). To the best of our knowledge, this is the first case report describing hCG secretion in an extra-adrenal paraganglioma
