Abstract: Background: Cognitive problems in patients with post-traumatic stress disorder (PTSD) include poor concentration and impaired memory. Prevalence of PTSD in all aspects of life is 8% in USA. Regarding the importance of memory in functional levels, this study was performed to review memory status in these patients. Methods: Fifty male war veterans with PTSD and major depression and 50 male non-veterans with depression participated in this study performed at psychiatric outpatient ward in Baqiyatallah hospital during 2008-2009. The patients met the DSM-IV diagnostic criteria. Depression severity, sex, age, educational level, and marital status were matched in both groups. A psychologist completed demographic and Mississippi questionnaires, PTSD checklist (PCL), beck depression Inventory and wechsler memory scale. The collected data were analyzed using SPSS software (version 11.0). A P-value smaller than 0.05 was considered significant.Results: The mean age of the veterans and non-veterans was 43.9±4.7 and 42±9.4 years, respectively. Memory status did not differ between the two groups (P>0.05). There was no statistically significant correlation between duration and severity of PTSD with memory impairment (P>0.05). A negative correlation was found between personal and general information with re-experiencing in the veterans (P<0.05). Impaired memory was correlated with age greater than 45, educational level lower than high school diploma, severity of depression and longer participation in war. Conclusion: Although both PTSD and major depression affected memory, but memory status did not differ between patients with PTSD and depression and patients with chronic depression.
Kikuchi-Fujimoto Disease in Patients with Sjögren’s Syndrome  [PDF]

Abstract:

Sjogren’s syndrome is a chronic autoimmune exocrinopathy associated with dry eyes and dry mouth as major clinical manifestations. It is characterized by lymphocytic infiltration of lacrimal and salivary glands and autoantibody production, especially anti-Ro (or SSA) and anti-La (or SSB). Lymphoproliferative disorders are a feature of Sjogren’s syndrome, and can be considered an extraglandular manifestation of the disease. Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a rare form of lymphadenitis. It is reported more often in young adult women with localized lymphadenopathy (usually cervical), fever, rashes, and leukopenia. It is a self-limiting disease with resolution within 1 - 4 months in almost all patients. Sjogren’s syndrome has been reported in patients with other systemic diseases including SLE and lymphomas. Here we present a patient with Kikuchi-Fujimoto disease who developed Sjogren’s Syndrome 8 years after her diagnosis of Kikuchi-Fujimoto disease.

Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.411183
Abstract:

In this work, studied electrical conductivity(s) and annealing of radiation defects in crystals of n-InP are irradiated by electrons energy of 6 MeV and doses of 1017 el/cm2 (centimeter) and 2 × 1017 el/cm2 (centimeter). It is shown that alongside point defects (in the form of complexes with impurity atoms in crystals of n-InP) also form the complex defects of the type of disordered areas, annealing of which proceeds at T > 300°C that binds accumulating radiation defects.

Current Status of Gil-Vernet Trigonoplasty Technique

Advances in Urology , 2008, DOI: 10.1155/2008/536428
Abstract: Significant controversy exists regarding vesicoureteral reflux (VUR) management, due to lack of sufficient prospective studies. The rationale for surgical management is that VUR can cause recurrent episodes of pyelonephritis and long-term renal damage. Several surgical techniques have been introduced during the past decades. Open anti-reflux operations have high success rate, exceeding 95%, and long durability. The goal of this article is to review the Gil-Vernet trigonoplasty technique, which is a simple and highly successful technique but has not gained the attention it deserves. The mainstay of this technique is approximation of medial aspects of ureteral orifices to midline by one mattress suture. A unique advantage of Gil-Vernet trigonoplasty is its bilateral nature, which results in prevention from contralateral new reflux. Regarding not altering the normal course of the ureter in Gil-Vernet procedure, later catheterization of and retrograde access to the ureter can be performed normally. There is no report of ureterovesical junction obstruction following Gil-Vernet procedure. Gil-Vernet trigonoplasty can be performed without inserting a bladder catheter and drain on an outpatient setting. Several exclusive advantages of Gil-Vernet trigonoplasty make it necessary to reconsider the technique role in VUR management.

Recent Subthreshold Design Techniques

Abstract: Considering the variety of studies that have been reported in low-power designing era, the subthreshold design trend in Very Large Scale Integrated (VLSI) circuits has experienced a significant development in recent years. Growing need for the lowest power consumption has been the primary motivation for increase in research in this area although other goals, such as lowest energy delay production, have also been achieved through sub-threshold design. There are, however, few extensive studies that provide a comprehensive design insight to catch up with the rapid pace and large-scale implementations of sub-threshold digital design methodology. This paper presents a complete review of recent studies in this field and explores all aspects of sub-threshold design methodology. Moreover, near-threshold design and low-power pipelining are also considered to provide a general review of sub-threshold applications. At the end, a discussion about future directions in ultralow-power design is also included. 1. Introduction Subthreshold digital circuits are now well known to ultralow-power designers and have frequently and successfully been used for applications such as implanted sensors and mobile peripheral processors. However, performance degradation and high sensitivity to Process/Voltage/Temperature (PVT) variations are the primary challenges that have confined subthreshold circuit implementations to low-activity applications. There are many recent review papers covering the subjects of sub/near-threshold digital design and their challenges. The goal of this review, however, is to cover a boarder range of designs, to show the interrelation of different solutions for low-power digital design and review the recent updates and new advances in ultralow-power era. Some of useful and comprehensive reviews are as follows. Authors in [1] presented a detailed review that discussed the advantages/disadvantages of subthreshold design, and mathematical equations required for the subthreshold circuits. The paper also covered variation problems briefly and presented subthreshold design techniques for Static Random Access Memories (SRAM) design followed by design techniques for multiprocessing. These discussions make [1] one of the most inclusive early papers. In [2] authors have focused on variations and leakage reduction, to a greater extent, and besides DC-DC converters have also been discussed. In one of the recent reviews, authors (see [3]) presented a detailed review of subthreshold design by exploring subthreshold modelling methods, a few leakage reduction techniques, a
Computational Prediction of Intronic microRNA Targets using Host Gene Expression Reveals Novel Regulatory Mechanisms

Abstract: Approximately half of known human miRNAs are located in the introns of protein coding genes. Some of these intronic miRNAs are only expressed when their host gene is and, as such, their steady state expression levels are highly correlated with those of the host gene's mRNA. Recently host gene expression levels have been used to predict the targets of intronic miRNAs by identifying other mRNAs that they have consistent negative correlation with. This is a potentially powerful approach because it allows a large number of expression profiling studies to be used but needs refinement because mRNAs can be targeted by multiple miRNAs and not all intronic miRNAs are co-expressed with their host genes.
