Study of simple sequence repeat (SSR) polymorphism for biotic stress resistance in elite rice variety JGL 1798
To provide ready to use markers for back ground selection in marker assisted breeding of rice, we used GPP 2 as donor parent for xa13, Xa21, Gm4 resistance to bacterial blight, gall midge and NLR 145 as another donor parent for Pi-kh gene resistance to blast and JGL 1798 as recurrent parent was investigated using 128 simple sequence repeat (SSR) primers covered on chromosome number 1-12. The results reveal that 36 HRM primers showed distinct polymorphism among the donor and recurrent parents studied indicating the robust nature of microsatellites in revealing polymorphism. Based on this study, the large range of similarity values for related cultivars using microsatellites provides greater confidence for the assessment of simple sequence repeats (SSR) polymorphism.Keywords: Simple sequence repeats (SSR), parental polymorphism, JGL 1798, hyper variable markersAfrican Journal of Biotechnology Vol. 12(40), pp. 5833-583
Healthcare workers and health care-associated infections: knowledge, attitudes, and behavior in emergency departments in Italy
<p>Abstract</p> <p>Background</p> <p>This survey assessed knowledge, attitudes, and compliance regarding standard precautions about health care-associated infections (HAIs) and the associated determinants among healthcare workers (HCWs) in emergency departments in Italy.</p> <p>Methods</p> <p>An anonymous questionnaire, self-administered by all HCWs in eight randomly selected non-academic acute general public hospitals, comprised questions on demographic and occupational characteristics; knowledge about the risks of acquiring and/or transmitting HAIs from/to a patient and standard precautions; attitudes toward guidelines and risk perceived of acquiring a HAI; practice of standard precautions; and sources of information.</p> <p>Results</p> <p>HCWs who know the risk of acquiring Hepatitis C (HCV) and Human Immunodeficiency Virus (HIV) from a patient were in practice from less years, worked fewer hours per week, knew that a HCW can transmit HCV and HIV to a patient, knew that HCV and HIV infections can be serious, and have received information from educational courses and scientific journals. Those who know that gloves, mask, protective eyewear, and hands hygiene after removing gloves are control measures were nurses, provided care to fewer patients, knew that HCWs' hands are vehicle for transmission of nosocomial pathogens, did not know that a HCW can transmit HCV and HIV to a patient, and have received information from educational courses and scientific journals. Being a nurse, knowing that HCWs' hands are vehicle for transmission of nosocomial pathogens, obtaining information from educational courses and scientific journals, and needing information were associated with a higher perceived risk of acquiring a HAI. HCWs who often or always used gloves and performed hands hygiene measures after removing gloves were nurses, provided care to fewer patients, and knew that hands hygiene after removing gloves was a control measure.</p> <p>Conclusions</p> <p>HCWs have high knowledge, positive attitudes, but low compliance concerning standard precautions. Nurses had higher knowledge, perceived risk, and appropriate HAIs' control measures than physicians and HCWs answered correctly and used appropriately control measures if have received information from educational courses and scientific journals.</p
Percussion hemoglobinuria - a novel term for hand trauma-induced mechanical hemolysis: a case report
<p>Abstract</p> <p>Introduction</p> <p>Extracorpuscular hemolysis caused by mechanical trauma has been well described in relation to lower extremity use, such as in soldiers and runners. Terms such as "march hemoglobinuria", "foot strike hemolysis" and "runners hemoglobinuria" have previously been coined and are easily recalled. Newer cases, however, are being identified in individuals vigorously using their upper extremities, such as drum players who use their hands to strike the instrument. Given the increased recognition of upper extremity-related mechanical hemolysis and hemoglobinuria in drummers, and the use of hand drumming worldwide, we would like introduce a novel term for this condition and call it "percussion hemoglobinuria".</p> <p>Case presentation</p> <p>A 24-year-old Caucasian man presented with reddish brown discoloration of his urine after playing the djembe drum. Urine examination after a rigorous practice session revealed blood on the dipstick, and 0 to 2 red blood cells per high power field microscopically. The urine sample was negative for myoglobulin. Other causes of hemolysis and hematuria were excluded and cessation of drum playing resulted in resolution of his symptoms.</p> <p>Conclusions</p> <p>The association of mechanical trauma-induced hemoglobinuria and playing hand percussion instruments is increasingly being recognized. We, however, feel that the true prevalence is higher than what has been previously recorded in the literature. By coining the term "percussion hemoglobinuria" we hope to raise the awareness of screening for upper extremity trauma-induced mechanical hemolysis in the evaluation of a patient with hemoglobinuria.</p

Contains fulltext :
108485.pdf (publisher's version ) (Open Access)INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate short-term anatomic and functional outcomes and safety of laparoscopic sacrocolpopexy with bone anchor fixation. METHODS: A prospective cohort study of women undergoing laparoscopic sacrocolpopexy between 2004 and 2009. Anatomic outcome was assessed using the pelvic organ prolapse quantification score (POP-Q). Functional outcomes were assessed using the Urogenital Distress Inventory, Defecatory Distress Inventory, and the Incontinence Impact Questionnaire preoperatively and at 6 months postoperatively. The Wilcoxon signed rank test was used to test differences between related samples. RESULTS: Forty-nine women underwent laparoscopic sacrocolpopexy. The objective success rate in the apical compartment was 98%, subjective success rate was 79%. One mesh exposure (2%) was found. One conversion was necessary due to injury to the ileum. CONCLUSIONS: Laparoscopic sacrocolpopexy with bone anchor fixation is a safe and efficacious treatment for apical compartment prolapse. It provides excellent apical support and good functional outcome 6 months postoperatively.1 april 201
Recipient and donor thrombophilia and the risk of portal venous thrombosis and hepatic artery thrombosis in liver recipients
<p>Abstract</p> <p>Background</p> <p>Vascular complications, such as HAT, are an important cause of graft loss and recipient mortality. We aimed to characterize post-transplant thrombotic events in a cohort of liver transplant recipients, and identify independent risk factors for these complications.</p> <p>Methods</p> <p>We conducted a thrombophilic study of 293 orthotopic liver transplants performed in the Digestive Surgery Department of the 12 de Octubre Hospital (Madrid, Spain) between January 2001 and December 2006.</p> <p>Results</p> <p>The most frequent post-transplant thrombotic events were HAT (9%) and PVT (1.7%). The one variable associated with post-transplant thrombotic event was a high fibrinogen level in the global cohort of liver transplantation. But toxicity as event post-OLT has been associated with post-transplant thrombotic event in the retrospective group and high fibrinogen level and low protein C levels were associated post-transplant thrombotic event in the prospective group. Liver disease relapse (HR 6.609, p < 0.001), high levels of FVIII (HR 1.008, p = 0.019)) and low levels of antithrombin (HR 0.946, p < 0.001) were associated with poor overall survival (OS).</p> <p>In conclusion, high fibrinogen and decreased protein C levels were associated with allograft thrombosis. Further studies are required in order to assess the clinical relevance of these parameters in prospective studies and to study the effect of anticoagulation prophylaxis in this group of risk.</p
Characterization of High-Fat, Diet-Induced, Non-alcoholic Steatohepatitis with Fibrosis in Rats
An ideal animal model is necessary for a clear understanding of the etiology, pathogenesis, and mechanisms of human non-alcoholic steatohepatitis (NASH) and for facilitating the design of effective therapy for this condition. We aimed to establish a rat model of NASH with fibrosis by using a high-fat diet (HFD). Male Sprague–Dawley (SD) rats were fed a HFD consisting of 88 g normal diet, 10 g lard oil, and 2 g cholesterol. Control rats were fed normal diet. Rats were killed at 4, 8, 12, 16, 24, 36, and 48 weeks after HFD exposure. Body weight, liver weight, and epididymal fat weight were measured. Serum levels of fasting glucose, triglyceride, cholesterol, alanine aminotransferase (ALT), free fatty acids (FFA), insulin, and tumor necrosis factor-alpha (TNF-α) were determined. Hepatic histology was examined by H&E stain. Hepatic fibrosis was assessed by VG stain and immunohistochemical staining for transforming growth factor beta 1 (TGF-β1), and alpha-smooth-muscle actin (α-SMA). The liver weight and liver index increased from week 4, when hepatic steatosis was also observed. By week 8, the body weight and epididymal fat weight started increasing, which was associated with increased serum levels of FFA, cholesterol, and TNF-α, as well as development of simple fatty liver. The serum ALT level increased from week 12. Steatohepatitis occurred from weeks 12 through 48. Apparent hepatic perisinosodial fibrosis did not occur until week 24, and progressed from week 36 to 48 with insulin resistance. Therefore, this novel model may be potentially useful in NASH study
Rice biofortification: breeding and genomic approaches for genetic enhancement of grain zinc and iron contents
Rice is a highly consumed staple cereal cultivated predominantly in Asian countries, which share 90% of global rice production. Rice is a primary calorie provider for more than 3.5 billion people across the world. Preference and consumption of polished rice have increased manifold, which resulted in the loss of inherent nutrition. The prevalence of micronutrient deficiencies (Zn and Fe) are major human health challenges in the 21st century. Biofortification of staples is a sustainable approach to alleviating malnutrition. Globally, significant progress has been made in rice for enhancing grain Zn, Fe, and protein. To date, 37 biofortified Fe, Zn, Protein and Provitamin A rich rice varieties are available for commercial cultivation (16 from India and 21 from the rest of the world; Fe > 10 mg/kg, Zn > 24 mg/kg, protein > 10% in polished rice as India target while Zn > 28 mg/kg in polished rice as international target). However, understanding the micronutrient genetics, mechanisms of uptake, translocation, and bioavailability are the prime areas that need to be strengthened. The successful development of these lines through integrated-genomic technologies can accelerate deployment and scaling in future breeding programs to address the key challenges of malnutrition and hidden hunger
Kidney transplantation in childhood: mental health and quality of life of children and caregivers
Our objective was to assess the mental health and health-related quality of life (HRQOL) in children and their parents after renal transplantation (TX) compared to healthy controls and children with acute lymphoblastic leukemia (ALL) and to identify possible health status variables associated with impaired mental health and HRQOL. Thirty-eight TX children with a median age of 13 (range 3–19) years were investigated. Mental health was assessed by the Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales and the Strength and Difficulties Questionnaire (SDQ-20). Each mother’s own mental health and QOL were assessed by the General Health Questionnaire (GHQ-30) and the Quality of Life Scale (QOLS). Forty children with ALL [median age 11 (8.5–15.4) years] and 42 healthy children [median age 11 (8.9– 15) years] served as controls. Treadmill exercise results from 22 of the 38 patients were included in the analysis. TX children showed significantly higher levels of mental health problems and lower HRQOL at 2 to 16 years after transplantation compared to both control groups. Body mass index and maximal oxygen uptake (n = 22/38) were significant predictors of child mental health (SDQ) and child QOL (PedsQL), respectively. Based on these results, we suggest that rehabilitation after TX should include a focus on physical activity and QOL to reduce interconnected physical and psychological morbidity in kidney TX children
