Genetic variation among Northern and Southern Egyptian buffaloes using polymerase chain reaction-random amplified polymorphic DNA (PCR-RAPD)

The domestic water buffalo is a species of great economic potential, especially in developing countries like Egypt. Egyptian buffalo have been classified according to minor phenotypic differences and their geographical locations. Few studies have taken place to investigate the genetic variations in Egyptian buffalo using  microsatellites analysis. In the present study, 11 random primers were analyzed for the genetic diversity  determination between Northern and Southern Egyptian buffaloes using polymerase chain reaction-random  amplified polymorphic DNA (PCR-RAPD) analysis. 169 bands were amplified for the analyzed 11 random  primers, from which 160 bands (94.67%) for North populations and 168 bands for South population (99.41%).  Out of the 160 amplified bands in North populations, 152 bands were polymorphic with a percentage of 89.94% and only one specific band (0.59%). In South population, all 168 amplified bands were polymorphic, nine bands (5.33%) were specific for this population. The identity index and the genetic distance between North and South populations were measured. The results showed that the two tested populations have the same origin and  belong to one breed without significant genetic difference between their animals.Key words: Buffalo, genetic diversity, polymerase chain reaction (PCR), random amplified polymorphic DNA (RAPD)

PENINGKATAN KECAKAPAN MASYARAKAT SONAF HONIS BONEN DALAM BUDIDAYA DAN PENGOLAHAN CABAI

Ketersediaan buah cabai di pasaran umumnya tidak stabil. Saat panen raya suplai cabai melimpah sehingga harganya rendah. Sebaliknya saat musim hujan, suplai cabai sangat terbatas sehingga harganya melonjak. Masyarakat desa Oeltua Kabupaten Kupang umumnya adalah petani dan peternak. Salah satu tanaman yang banyak diusahakan adalah cabai. Melalui kegiatan PKM ini dilakukan transfer ilmu pengetahuan dan keterampilan bagi Kelompok Tani Kaum Ibu Sonaf Honis Bonen dan masyarakat setempat untuk meningkatkan kecakapan dalam budidaya cabai serta pengolahan cabai, yaitu dengan pemanfaatan mulsa plastik hitam perak serta penggunaan food dehydrator dalam pengolahan buah cabai.

Graded Contractions of Affine Kac-Moody Algebras

The method of graded contractions, based on the preservation of the automorphisms of finite order, is applied to the affine Kac-Moody algebras and their representations, to yield a new class of infinite dimensional Lie algebras and representations. After the introduction of the horizontal and vertical gradings, and the algorithm to find the horizontal toroidal gradings, I discuss some general properties of the graded contractions, and compare them with the In\"on\"u-Wigner contractions. The example of $\hat A_2$ is discussed in detail.Comment: 23 pages, Ams-Te

Surgical treatment of rectal prolapse: experience and late results with 51 patients

The "best" surgical technique for the management of complete rectal prolapse remains unknown. Due to its low incidence, it is very difficult to achieve a representative number of cases, and there are no large prospective randomized trials to attest to the superiority of one operation over another. PURPOSE: Analyze the results of surgical treatment of complete rectal prolapse during 1980 and 2002. METHOD: Retrospective study. RESULTS: Fifty-one patients underwent surgical treatment during this period. The mean age was 56.7 years, with 39 females. Besides the prolapse itself, 33 patients complained of mucous discharge, 31 of fecal incontinence, 14 of constipation, 17 of rectal bleeding, and 3 of urinary incontinence. Abdominal operations were performed in 36 (71%) cases. Presacral rectopexy was the most common abdominal procedure (29 cases) followed by presacral rectopexy associated with sigmoidectomy (5 cases). The most common perineal procedure was perineal rectosigmoidectomy associated with levatorplasty (12 cases). Intraoperative bleeding from the presacral space developed in 2 cases, and a rectovaginal fistula occurred in another patient after a perineal rectosigmoidectomy. There were 2 recurrences after a mean follow-up of 49 months, which were treated by reoperation. CONCLUSION: Abdominal and perineal procedures can be used to manage complete rectal prolapse with safety and good long-term results. Age, associated medical conditions, and symptoms of fecal incontinence or constipation are the main features that one should bear in mind in order to choose the best surgical approach.A técnica cirúrgica mais apropriada para a correção da procidência retal permanece motivo de controvérsia. Por se tratar de afecção pouco freqüente, há dificuldade de avaliação de número adequado de pacientes em estudos randomizados e existe pouca evidência para comprovar a superioridade de alguma das técnicas. OBJETIVO: Analisar os resultados de eficácia e segurança do tratamento cirúrgico da procidência retal em pacientes operados entre 1980 e 2002. MÉTODO: Estudo retrospectivo. RESULTADOS: Cinqüenta e um pacientes foram operados. A idade média foi de 56,7 anos e 39 eram mulheres. Além do prolapso, 33 pacientes queixavam-se de eliminação de muco, 31 tinham incontinência anal, 14 apresentavam constipação, 17 com sangramento retal e 3 incontinência urinária. Operações abdominais foram realizadas em 36 (71%) casos, sendo a retopexia sem prótese a operação mais realizada (29 casos) seguida pela retossigmoidectomia com retopexia (5 casos). A operação perineal mais realizada foi a retossigmoidectomia com plastia dos elevadores (12 casos). O sangramento sacral foi a única complicação intra-operatória e ocorreu em dois casos. Como complicação pós-operatória, houve um caso de fístula retovaginal após operação de retossigmoidectomia perineal. Após seguimento médio de 49 meses, observamos recidiva da procidência em 2 casos. CONCLUSÕES: Operações abdominais e perineais podem ser utilizadas com segurança e eficácia no tratamento cirúrgico da procidência do reto. A idade, a presença de afecções associadas, comorbidades e os sintomas de constipação e incontinência são as principais variáveis envolvidas na escolha da operação. As operações de retopexia abdominal e retossigmoidectomia perineal estão associadas a bons resultados

Pomegranate (Punica graantum) Peels as an Agricultural Waste for Removing of CD(II), CR(VI), CU(II), NI(II), PB(II) and ZN(II) from Their Aqueous Solutions

Pomegranate (Punica graantum) peels as an agricultural waste was used as an adsorbent for removal of Cd, Cr, Cu, Ni, Pb and Zn ions from simulated aqueous solutions. The adsorption process was carried out using the batch method. Various effective parameters such as pH, initial metal ion concentration, and adsorbent dose, shaking time, particle size and temperature were investigated. Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM) of Punica graantum peels were done. The efficiency of Punica graantum peels toward removal of metal ions was ordered as Pb2+ \u3c Cr6+ \u3c Cu2+ \u3c Cd2+ \u3c Zn2+ \u3c Ni2+, with the corresponding values of 92.8%, 84.6%, 52.8%, 38%, 25.4% and 22.8%, respectively

Biallelic mutations in valyl-tRNA synthetase gene VARS are associated with a progressive neurodevelopmental epileptic encephalopathy.

Aminoacyl-tRNA synthetases (ARSs) function to transfer amino acids to cognate tRNA molecules, which are required for protein translation. To date, biallelic mutations in 31 ARS genes are known to cause recessive, early-onset severe multi-organ diseases. VARS encodes the only known valine cytoplasmic-localized aminoacyl-tRNA synthetase. Here, we report seven patients from five unrelated families with five different biallelic missense variants in VARS. Subjects present with a range of global developmental delay, epileptic encephalopathy and primary or progressive microcephaly. Longitudinal assessment demonstrates progressive cortical atrophy and white matter volume loss. Variants map to the VARS tRNA binding domain and adjacent to the anticodon domain, and disrupt highly conserved residues. Patient primary cells show intact VARS protein but reduced enzymatic activity, suggesting partial loss of function. The implication of VARS in pediatric neurodegeneration broadens the spectrum of human diseases due to mutations in tRNA synthetase genes

Gridded global surface ozone metrics for atmospheric chemistry model evaluation

The concentration of ozone at the Earth's surface is measured at many locations across the globe for the purposes of air quality monitoring and atmospheric chemistry research. We have brought together all publicly available surface ozone observations from online databases from the modern era to build a consistent data set for the evaluation of chemical transport and chemistry-climate (Earth System) models for projects such as the Chemistry-Climate Model Initiative and Aer-Chem-MIP. From a total data set of approximately 6600 sites and 500 million hourly observations from 1971-2015, approximately 2200 sites and 200 million hourly observations pass screening as high-quality sites in regionally representative locations that are appropriate for use in global model evaluation. There is generally good data volume since the start of air quality monitoring networks in 1990 through 2013. Ozone observations are biased heavily toward North America and Europe with sparse coverage over the rest of the globe. This data set is made available for the purposes of model evaluation as a set of gridded metrics intended to describe the distribution of ozone concentrations on monthly and annual timescales. Metrics include the moments of the distribution, percentiles, maximum daily 8-hour average (MDA8), sum of means over 35 ppb (daily maximum 8-h; SOMO35), accumulated ozone exposure above a threshold of 40 ppbv (AOT40), and metrics related to air quality regulatory thresholds. Gridded data sets are stored as netCDF-4 files and are available to download from the British Atmospheric Data Centre (doi:10.5285/08fbe63d-fa6d-4a7a-b952-5932e3ab0452). We provide recommendations to the ozone measurement community regarding improving metadata reporting to simplify ongoing and future efforts in working with ozone data from disparate networks in a consistent manner

Modulatory Effect of Monochromatic Blue Light on Heat Stress Response in Commercial Broilers

In a novel approach, monochromatic blue light was used to investigate its modulatory effect on heat stress biomarkers in two commercial broiler strains (Ross 308 and Cobb 500). At 21 days old, birds were divided into four groups including one group housed in white light, a second group exposed to blue light, a 3rd group exposed to white light + heat stress, and a 4th group exposed to blue light + heat stress. Heat treatment at 33°C lasted for five h for four successive days. Exposure to blue light during heat stress reduced MDA concentration and enhanced SOD and CAT enzyme activities as well as modulated their gene expression. Blue light also reduced the degenerative changes that occurred in the liver tissue as a result of heat stress. It regulated, though variably, liver HSP70, HSP90, HSF1, and HSF3 gene expression among Ross and Cobb chickens. Moreover, the Cobb strain showed better performance than Ross manifested by a significant reduction of rectal temperature in the case of H + B. Furthermore, a significant linear relationship was found between the lowered rectal temperature and the expression of all HSP genes. Generally, the performance of both strains by most assessed parameters under heat stress is improved when using blue light
