A hyperthermophilic and thermostable xylanase of 82 kDa (TtXynA) was purified from the culture supernatant of T. terrestris Co3Bag1, grown on carboxymethyl cellulose (CMC), and characterized biochemically. TtXynA showed optimal xylanolytic activity at pH 5.5 and at 85 °C, and retained more than 90% of its activity at a broad pH range (4.5-10). The enzyme is highly thermostable with a half-life of 23.1 days at 65 °C, and active in the presence of several metal ions. Circular dichroism spectra strongly suggest the enzyme gains secondary structures when temperature increases...

PURPOSE: The impact of the low anterior resection syndrome (LARS) on quality of life has underscored the importance of measuring functional outcomes after treatment for rectal cancer. The aim of this study was to evaluate whether the LARS score as a single questionnaire was useful enough in the clinical setting. METHODS: Patients treated by curative anterior resection for rectal cancer were sent the LARS score and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 questionnaires by post...

Corn stover was treated using low-moisture anhydrous ammonia (LMAA) at controlled ammoniation temperature. Moisturized corn stover (50 % moisture) was contacted with anhydrous ammonia (0.1 g NH3/g-biomass) in a batch reactor at various temperatures (ambient to 150 °C). After ammoniation at elevated and controlled temperature, ammoniated corn stover was pretreated at various temperatures (60-150 °C) for 72-144 h. Change in composition was marginal at low pretreatment temperature but was relatively severe with pretreatment at high temperature (130-150 °C)...

OBJECTIVE: We present a descriptive analysis of our cases of sphincterotomy followed by papillary large balloon dilation in a single session (ES-LBD) in the management of difficult to extract calculi, with the objective of assessing rates of therapeutic success and complications in local experience. MATERIAL AND METHODS: ERCP procedures with ES-LBD performed for choledocholithiasis between January 2009 and December 2014 in patients older than 18 years and without preexistent sphincterotomy were selected from records of the Gastroenterology Service at Cayetano Heredia National Hospital...

Multiple stressors threaten biodiversity and ecosystem integrity, imposing new challenges to ecosystem management and restoration. Ecosystem managers are required to address and mitigate the impact of multiple stressors, yet the knowledge required to disentangle multiple-stressor effects is still incomplete. Experimental studies have advanced the understanding of single and combined stressor effects, but there is a lack of a robust analytical framework, to address the impact of multiple stressors based on monitoring data...

The Peruvian Andes are the home of 27 species of frogs of the genus Telmatobius, many of which are critically endangered. Illegal trade of adult frogs for purported medical properties likely represents the major threat facing these species. This activity, besides reducing their populations, may contribute to the dissemination of the fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, a disease posing a threat to many populations of amphibians. We screened frogs confiscated by the Administration of Forestry and Wildlife in Lima, Peru, for Bd...

UNLABELLED: The implementation of evidence-based strategies to promote colorectal cancer (CRC) screening remains challenging. The aim of this study is to evaluate two strategies to implement an evidence-based intervention to promote CRC screening in Filipino American community organizations. Twenty-two community organizations were randomized to either a basic or enhanced implementation strategy. In both arms, community health advisors recruited participants non-adherent to CRC screening guidelines, conducted educational sessions, distributed print materials and free fecal occult blood test kits, reminded participants to get screened, and mailed letters to participants' providers...

Human capital requires opportunities to develop and capacity to overcome challenges, together with an enabling environment that fosters critical and disruptive innovation. Exploring such features is necessary to establish the foundation of solid long-term partnerships. In this paper we describe the experience of the CRONICAS Centre of Excellence in Chronic Diseases, based at Universidad Peruana Cayetano Heredia in Lima, Peru, as a case study for fostering meaningful and sustainable partnerships for international collaborative research...

BACKGROUND: Arterial puncture for arterial blood gases (ABG) analysis can be a risky, painful, difficult-to-perform procedure that is often insufficiently practised and generates stress and discomfort amongst patients and healthcare professionals. Self-efficacy is a key component in the acquisition of procedural skills. Therefore, professionals' self-efficacy in arterial puncture should be measured before attempting the procedure on real patients. OBJECTIVE: To develop and psychometrically assess a self-efficacy scale in arterial puncture...

BACKGROUND/OBJECTIVES: Oral anticholinergic drugs, such as oxybutynin, are often used in the treatment of hyperhidrosis, but few studies have focused on dosing strategies for children. The objective was to assess the effectiveness and safety of individualized dosing regimens of oral oxybutynin for treating primary focal hyperhidrosis (PFH) in children and teenagers. METHODS: A prospective study was performed including patients who initiated treatment for hyperhidrosis between November 2011 and November 2014...

INTRODUCTION: Cough is a key symptom of tuberculosis (TB) as well as the main cause of transmission. However, a recent literature review found that cough frequency (number of coughs per hour) in patients with TB has only been studied once, in 1969. The main aim of this study is to describe cough frequency patterns before and after the start of TB treatment and to determine baseline factors that affect cough frequency in these patients. Secondarily, we will evaluate the correlation between cough frequency and TB microbiological resolution...

Models used to explain the social organization of primates suggest that variation in daily path length (DPL) is a response to variation in resource distribution and the intensity of intragroup feeding competition. However, daily path length may be affected by a number of other factors including the availability and distribution of nutritionally complementary food items, temperature which can influence activity budget, patterns of subgrouping, and the frequency and function of intergroup encounters. In this 6-month study (total 495 hr of quantitative data), we examined daily path lengths in two neighboring groups of black and gold howler monkeys (Alouatta caraya) inhabiting a semi-deciduous gallery forest in San Cayetano (27° 30'S, 58° 41'W), in the northwest province of Corrientes, Argentina...

BACKGROUND/OBJECTIVES: Although many treatments are available to address hyperhidrosis, the results are not always satisfactory. The aim of the study was to assess the effectiveness, optimal dosage regimen and long-term safety of oral oxybutynin in the treatment of hyperhidrosis. METHODS: A retrospective review was performed on 110 patients who underwent treatment for hyperhidrosis between February 2007 and December 2013. Their response to treatment was evaluated using the hyperhidrosis disease severity scale at baseline, 3 and 12 months...

Prefoldin is a molecular chaperone complex that regulates tubulin function in mitosis. Here, we show that Prefoldin depletion results in disruption of neuroblast polarity, leading to neuroblast overgrowth in Drosophila larval brains. Interestingly, co-depletion of Prefoldin and Partner of Inscuteable (Pins) leads to the formation of gigantic brains with severe neuroblast overgrowth, despite that Pins depletion alone results in smaller brains with partially disrupted neuroblast polarity. We show that Prefoldin acts synergistically with Pins to regulate asymmetric division of both neuroblasts and Intermediate Neural Progenitors (INPs)...

PURPOSE: We aimed to quantify and compare dietary non-enzymatic antioxidant capacity (NEAC), estimated using two dietary assessment methods, and to explore its relationship with plasma NEAC. METHODS: Fifty healthy subjects volunteer to participate in this study. Two dietary assessment methods [a food frequency questionnaire (FFQ) and a 24-hour recall (24-HR)] were used to collect dietary information. Dietary NEAC, including oxygen radical absorbance capacity (ORAC), total polyphenols, ferric-reducing antioxidant power (FRAP) and trolox equivalent antioxidant capacity, was estimated using several data sources of NEAC content in food...
