Post University is a proprietary university located in Waterbury, Connecticut. Post University was established in 1890. Prior to May 1990, it was known as Post College. It was affiliated with Teikyo University in Tokyo, Japan from 1990 to 2004, and during that time it was named Teikyo Post University. The university offers day, evening, and online courses, and has three satellite centers in Meriden, Danbury, and Wallingford. Wikipedia.

Visceral leishmaniasis (VL) is a vector-borne parasitic disease targeting tissue macrophages. It is among the most neglected infectious diseases. Classical manifestations of VL include chronic fever, hepatosplenomegaly, and pancytopenia. Most cases can be detected through serologic and molecular testing. Although therapy has historically relied on antimonials, newer therapeutic options include conventional or liposomal amphotericin B, paromomycin and miltefosine. Coinfection with human immunodeficiency virus (HIV) is increasingly reported and comes with additional diagnostic and therapeutic challenges. This article provides an up-to-date clinical review of VL focusing on clinical presentation, diagnosis, management, and issues related to HIV coinfection. © 2012 Elsevier Inc.

Some patients who sustain C5 to C7 nerve root injuries may demonstrate a natural recovery of elbow extension via the lower trunk; however the surgical effect of the reinnervation of the triceps brachii in such cases is still unknown. This study aims to determine the incidence of spontaneous recovery of the tricipital function and to identify the clinical and/or radiological predictors of poor spontaneous functional rehabilitation of elbow extension resulting from injuries of the upper roots of the brachial plexus. We conducted a review of the charts of 24 subjects sustaining an upper trunk syndrome with complete elbow extension palsy and who did not undergone any intervention for reinnervation of the triceps brachii in the primary brachial plexus surgery. Two years posttrauma, the muscle was scored as M0 in 12 patients (50%), M1 in 3 (12.5%), M2 in 1 (4.1%), M3 in 4 (16.6%), and M4 in 4 subjects (16.6%). The number of avulsed roots and the preoperative power of the latissimus dorsi did not demonstrate any significance in predicting the outcome of spontaneous elbow extension recovery; whereas the preoperative paralysis of the muscles for wrist extension was determined to be reliable predictive parameter for poor natural recovery of tricipital function.

Pumped heat electricity storage (PHES) has been recently suggested as a potential solution to the large-scale energy storage problem. PHES requires neither underground caverns as compressed air energy storage (CAES) nor kilometer-sized water reservoirs like pumped hydrostorage and can therefore be constructed anywhere in the world. However, since no large PHES system exists yet, and theoretical predictions are scarce, the efficiency of such systems is unknown. Here we formulate a simple thermodynamic model that predicts the efficiency of PHES as a function of the temperature of the thermal energy storage at maximum output power. The resulting equation is free of adjustable parameters and nearly as simple as the well-known Carnot formula. Our theory predicts that for storage temperatures above 400 C PHES has a higher efficiency than existing CAES and that PHES can even compete with the efficiencies predicted for advanced-adiabatic CAES. © 2013 American Physical Society.

Psychiatrikē = Psychiatriki | Year: 2012
Self-rating Anxiety Scale (SAS), introduced by Zung, has been widely used in research and in clinical practice for the detection of anxiety. The present study aims at standardizing the Greek version of SAS. SAS consists of 20 items rated on a 1-4 likert type scale. The total SAS score may vary from 20 (no anxiety at all) to 80 (severe anxiety). Two hundred and fifty four participants (114 male and 140 female), psychiatric patients, physically ill and general population individuals, aged 45.40±11.35 years, completed the following: (a) a demographic characteristics' questionnaire, (b) the SAS Greek version, (c) the Spielberg's Modified Greek State-Trait Anxiety Scale (STAI-Gr.-X) and (d) the Zung Depression Rating Scale (ZDRS). Seventy six participants answered the SAS twice within a 12th-day median period of time. The following parameters were calculated: (a) internal consistency of the SAS in terms of Cronbach's α co-efficient, (b) its test-retest reliability in terms of the Intraclass Correlation Coefficient (ICC) and (c) its concurrent and convergent validities through its score's Spearman's rho correlations with both the state and trait subscales of STAI-Gr X and the ZDRS. In addition, in order to evaluate SAS' discriminant validity, the scale's scores of the three groups of participants (psychiatric patients, physically ill and general population individuals) were compared among each other, in terms of Kruskall Wallis and Mann Whitney U tests. SAS Cronbach's alpha equals 0.897 while ICC regarding its test-retest reliability equals 0.913. Spearman's rho concerning validity: (a) when SAS is compared to STAI-Gr.-X (state), equals it 0.767, (b) when SAS is compared to STAI-Gr. X (trait), it equals 0.802 and (c) when SAS is compared to ZDRS, it equals 0.835. The mentally ill scored significantly higher in SAS compared to both the healthy and the general population. In conclusion, the SAS Greek version presents very satisfactory psychometric properties regarding its reliability and validity as well.

Objective: To evaluate aqueous and ethanol extract of Cassia didymobotrya leaves against immature stages of Culex quinquefasciatus. Methods: The mortality rate of immature mosquitoes was tested in wide and narrow range concentration of the plant extract based on WHO standard protocol. The wide range concentration tested in the present study was 10 000, 1 000, 100, 10 and 1 mg/L and narrow range concentration was 50, 100, 150, 200 and 250 mg/L. Results: 2nd instar larvae exposed to 100 mg/L and above concentration of ethanol extract showed 100% mortality. Remaining stages such as 3rd, 4th and pupa, 100% mortality was observed at 1 000 mg/L and above concentration after 24 h exposure period. In aqueous extract all the stages 100% mortality was recorded at 1 000 mg/L and above concentration. In narrow range concentration 2nd instar larvae 100% mortality was observed at 150 mg/L and above concentration of ethanol extract. The remaining stages 100% mortality was recorded at 250 mg/L. In aqueous extract all the tested immature stages 100% mortality was observed at 250 mg/L concentration after 24 h exposure period. The results clearly indicate that the rate of mortality was based dose of the plant extract and stage of the mosquitoes. Conclusions: From this study it is confirmed and concluded that Cassia didymobotrya is having active principle which is responsible for controlling Culex quinquefasciatus. The isolation of bioactive molecules and development of simple formulation technique is important for large scale implementation. © 2012 Asian Pacific Tropical Biomedical Magazine.
