Physiological variables and molecular study of KLK2 and KLK3 among patient with benign prostatic hyperplasia

Prostatic hyperplasia is benign tumor occur in prostate. Benign prostatic hyperplasia is common disease in old men. The incidence of disease arises with increase in age. The patient with benign prostatic hyperplasia are estimated 20% of men in 40s old, and 90% in of men in 80s old, and main causes of prostatic hyperplasia are unknown but there is evidence referring to genetic and hormonal disorders that may cause the disease. This study includes 60 patients with prostatic hyperplasia with an average age of 64 years old and 30 samples as a control with same age group. The study obtained that there was significant association (P ≤ 0.05) between PSA (KLK3) and prostatic hyperplasia. Result also mentions that there was significant decrease in testosterone level and significant increase in dihydrotestosterone level. The present study for KLK2 and KLK3 genes showed molecular variation in both genes, varied between polymorphism and allele polymorphism. PCR amplification of specific primers of KLK2 gene showed polymorphisms ranged between 14%, 8%, 10%, and 6% in each KLK2a, KLK2b, KLK2c, and KLK2d primers respectively, while the allele polymorphism in KLK2c amplification with primer reaches 18% of patient. PCR amplification of specific primers of KLK3 gene showed polymorphisms ranged between 10%, 6%, 2%, and 4% in each KLK3a, KLK3b, KLK3c, and KLK3d primer respectively, and allele variation was not detected in amplification product of KLK3.Keywords: Hyperplasia, Prostatic specific antigen, KLK2, KLK

Incidence and Outcome of the Radial Nerve Injury following Open Fracture of the Humerus

Background: Radial nerve injury is the most common peripheral nerve injury associated with humeral shaft fracture and can result in significant motor impairment of the arm and the wrist.Objectives: To evaluate the incidence, pattern and outcome of the radial nerve injury following open fracture of the humerus.Material and Methods: This is a multicentre cross-sectional descriptive study. It included all patients with radial nerve injuries following open fracture of the humerus presented to orthopaedic departments of the major hospitals in Khartoum State, Sudan during the period June 2009 - June 2013. Collected data were processed using SPSS computer package version 17.Result: A total of 48 patients were included, 34 males and 14 females (ratio 1.5: 1). Mean age ± standard error of mean of 30.71 ± 1.78 years (ranged 4 – 64 years). About 60.4% of injuries were due to gunshot and 24 (50.0%) patients were from conflict areas. Most of the injuries were in left side in about 68.8% of patients. The common patterns of the humeral fractures associated with radial nerve injury were open comminuted and transverse of middle or distal part. Neurapraxia was common type of radial nerve injury in about 89.6%. About 91.7% of the patients were treated conservatively and 81.3% of them recovered completely.Conclusions: Most of the radial nerve injuries following open fracture of the humerus were caused by gunshot injury in male soldiers mainly in the distal and middle parts. The fractures were mainly displaced comminuted and transverse types. The commonest type of radial nerve palsy was neurapraxia in 89.6% of cases. Most of the patients were treated conservatively and 81.3% of them recovered spontaneously after the first two months.Keywords: Neurapraxia, Repair, Recovery, Gun shot, Sudan

Production of Lettuce Edible Vaccine for Cholera Disease Using Chloroplast Genetic Engineering.

Lettuce is one of the most important edible plant worldwide. At the timethat lettuce isthe candidate plant to carry the foreign vaccine gene forhuman. The B subunits of toxin of Vibrio cholerae(CTB) are candidatevaccine antigens. This research was conduct to express CTB gene in lettucechloroplast. Genesrequired in this study were obtained by polymerase chain reaction (PCR)technique using specific forward and reverse primers, and these genes wereCTB, BADH, prrnpromoter and many other regulatory genes. Some ofthese genes were isolated from their hosts and some were obtained fromprevious work available at Daniell laboratory. All these genes beside manytechniques for ligation, extension, sequencing, orientation confirmationwere used to construct the cassette vector pLS-BADH-LS-CTB whichcarries the gene of interest. In this work the CTB gene with BADH genewere transferred to the chloroplast of lettuce plant and selection oftransgenic plant was performed on the MS medium containing BA andNaCl without any antibiotic selectable marker. Integration of an unmodifiedCTB-coding sequence into chloroplast genomes (up to 1000 copies per cell)resulted in the accumulation of up to 6.2% of total soluble lettuce leavesprotein as functional oligomers (620-fold higher expression levels than thatof the unmodified CTB gene expressed via the nuclear genome). PCR andSouthern blot analyses confirmed stable integration of the CTB gene andBADH gene into the chloroplast genome in addition to the integration in theright orientation and in specific region between trnaI rnA.Western blotanalysis showed that the chloroplast synthesized CTB assembled intooligomers and were antigenically identical with purified native CT

Improvement of Lactuca sativa slat Tolerance by Plastid Transformation with BADH Gene

Salinity is one of the major factors that limits geographical distribution of plants and adversely affects crop productivity and quality.Here high-level expression of betaine aldehyde dehydrogenase (BADH) was reported in cultured explantsof lettuce via plastid genetic engineering. Lettuce (Lactucasativa) plant was primarilyexperimented for tolerance of betaine aldehyde (BA) and soudium chloride(NaCl) by tissue culture technique and it was found that the wild typelettuce tolerated 10 and 75 mM from each substance respectively. Genesrequired in this study were amplified by polymerase chain reaction (PCR)technique using specific forward and reverse primers, and these genes wereBADH, prrn promoter and many other regulatory genes. Some ofthese genes were isolated from their hosts and some were obtained fromprevious work available at Daniell laboratory. All these genes beside manytechniques for ligation, extension, sequencing, orientation confirmationwere used to construct the cassette vector pLS-BADH-LS whichcarries the gene of interest. Homoplasmic transgenic plants exhibiting high levels of salt tolerance were regenerated from bombarded cell cultures via somatic embryogenesis. Transgenic lettuce plants expressing BADH grew in the presence of high concentrations of NaCl (up to 150mM), the highest level of salt tolerance reported so far among genetically modified lettuce, and the tolerance to betaine aldehyde was 30 mM

Epithelial PD-L1 expression at tumor front predicts overall survival in a cohort of oral squamous cell carcinomas from Sudan

Background We recently described the tumor immune microenvironment (TIME) in oral squamous cell carcinomas (OSCC) from Sudan by assessing the core of the lesions. However, the invasive tumor front (ITF) is the most active part of OSCC lesions; thus, TIME should also be characterized at the ITF in this patient cohort. Objectives We aimed to evaluate patterns of immune cell infiltration at the ITF in a cohort of OSCC patients from Sudan previously investigated at the tumor center and their association with clinicopathological parameters. Methods This study was performed on a prospective cohort of 22 OSCC patients attending Khartoum Dental Teaching Hospital with a median follow-up of 48 months. Inflammatory infiltrate densities of CD4-, CD8-, FoxP3-, CD20-, CD66b-, M1 (CD80/CD68)-, M2 (CD163/CD68)-, and PD-L1-positive cells were assessed at the ITF by immunohistochemistry, followed by digital quantitative analysis at the stromal and epithelial compartments separately. Histopathological parameters such as the worst pattern of invasion, differentiation, and tumor budding (TB) were also assessed. Correlations between clinicopathological parameters and survival analysis were investigated using SPSS. Results All inflammatory cell subsets investigated were found to be higher in the stromal compartment as compared to the epithelial one, except for the PD-L1+ subset. Stromal infiltration with the CD8+ cell subset was associated with low TB. Kaplan–Meier analyses identified higher epithelial and stromal CD4+ cell subsets. The presence of PD-L1 was found to be associated with unfavorable overall survival. Further, Cox's regression analysis using an age- and tumor-stage-adjusted model identified epithelial PD-L1 expression at the ITF as the only independent prognosticator. Conclusions Epithelial PD-L1 expression at the ITF was found to be an independent prognostic biomarker for OSCC in a cohort of Sudanese patients.publishedVersio

The effect of cardioplegic supplementation with sildenafil on cardiac energetics in a piglet model of cardiopulmonary bypass and cardioplegic arrest with warm or cold cardioplegia

Cardioplegic cardioprotection strategies used during paediatric open-heart surgery remain suboptimal. Sildenafil, a phosphodiesterase 5 (PDE-5) inhibitor, has been shown to be cardioprotective against ischemia/reperfusion injury in a variety of experimental models and this study therefore tested the efficacy of supplementation of cardioplegia with sildenafil in a piglet model of cardiopulmonary bypass and arrest, using both cold and warm cardioplegia protocols. Piglets were anaesthetized and placed on coronary pulmonary bypass (CPB), the aorta cross-clamped and the hearts arrested for 60 min with cardioplegia with or without sildenafil (10 nM). Twenty minutes after removal of cross clamp (reperfusion), attempts were made to wean the pigs from CPB. Termination was carried out after 60 min reperfusion. Throughout the protocol blood and left ventricular tissue samples were taken for analysis of selected metabolites (using HPLC) and troponin I. In both the cold and warm cardioplegia protocols there was evidence that sildenafil supplementation resulted in faster recovery of ATP levels, improved energy charge (a measure of metabolic flux) and altered release of hypoxanthine and inosine, two purine catabolites. There was no effect on troponin release within the studied short timeframe. In conclusion, sildenafil supplementation of cardioplegia resulted in improved cardiac energetics in a translational animal model of paediatric CPB surgery

Measurement of the Neutron Radius of 208Pb Through Parity-Violation in Electron Scattering

We report the first measurement of the parity-violating asymmetry A_PV in the elastic scattering of polarized electrons from 208Pb. A_PV is sensitive to the radius of the neutron distribution (Rn). The result A_PV = 0.656 \pm 0.060 (stat) \pm 0.014 (syst) ppm corresponds to a difference between the radii of the neutron and proton distributions Rn - Rp = 0.33 +0.16 -0.18 fm and provides the first electroweak observation of the neutron skin which is expected in a heavy, neutron-rich nucleus.Comment: 6 pages, 1 figur

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

New Precision Limit on the Strange Vector Form Factors of the Proton

The parity-violating cross-section asymmetry in the elastic scattering of polarized electrons from unpolarized protons has been measured at a four-momentum transfer squared Q2 = 0.624 GeV and beam energy E =3.48 GeV to be A_PV = -23.80 +/- 0.78 (stat) +/- 0.36 (syst) parts per million. This result is consistent with zero contribution of strange quarks to the combination of electric and magnetic form factors G_E^s + 0.517 G_M^s = 0.003 +/- 0.010 (stat) +/- 0.004 (syst) +/- 0.009 (ff), where the third error is due to the limits of precision on the electromagnetic form factors and radiative corrections. With this measurement, the world data on strange contributions to nucleon form factors are seen to be consistent with zero and not more than a few percent of the proton form factors.Comment: 5 pages, 3 figure
