Many positive effects of additives on enzymatic hydrolysis of lignocellulosic materials have been investigated, but limited information has been reported on the use of long-chain fatty alcohols (LFAs) for enzymatic hydrolysis by biospired models. In this study, effects of LFAs on enzymatic hydrolysis were evaluated using biomimetic film asa structure model. LFAs clearly improved the digestibility of cellulose film from 65.1% to 77.9%, which was higher than that the digestibility of lignin-cellulose film from 53...

BACKGROUND: Isocapnic hyperventilation (IHV) is a method that shortens time to extubation after inhalation anaesthesia using hyperventilation (HV) without lowering airway CO2 . In a clinical trial on patients undergoing long-duration sevoflurane anaesthesia for major ear-nose-throat (ENT) surgery, we evaluated the utility of a technique for CO2 delivery (DCO2 ) to the inspiratory limb of a closed breathing circuit, during HV, to achieve isocapnia. METHODS: Fifteen adult ASA 1-3 patients were included...

INTRODUCTION: Tonsillectomy is considered as a therapeutic option in obstructive sleep apnoea syndrome (OSAS). Postoperative respiratory failure is a complication that can require respiratory support. The main objective of our study is to determine risk factors of postoperative respiratory complications in children undergoing tonsillectomy. MATERIAL AND METHODS: This is a retrospective single centre observational study including patients with unanticipated postoperative respiratory failure...

BACKGROUND: Analgesia following video-assisted thoracoscopic surgery (VATS) is important for the prevention of postoperative pulmonary complications. Various regional methods of anaesthesia are currently being used to achieve this goal. In our study, we aim to assess the effectiveness of SAPB on postoperative VATS analgesia in our study. METHODS: A total of 40 patients aged between 18 and 70 years, those who were in the Society of Anaesthesiologists (ASA) I-III class and underwent VATS were included in the study...

Incomplete stent apposition (ISA, also known as malapposition) is a complication that affects day-to-day coronary stenting procedures. ISA is more prominent in complex arterial geometries, such as curvature, asa result of the limited conformability of coronary stents. These malapposed struts disturb the otherwise near-wall laminar blood flow and form a micro-recirculation environment. The micro-recirculation environment is often associated with low wall shear stress (WSS) and upsets the delicate balance of vascular biology, providing possible nidus for thrombosis and restenosis...

Eicosanoid mediators play important roles in maintaining the physiological and pathophysiological homeostasis in the body. Their measurements, however, are rarely performed in clinical practice. In the present study, we analyzed 30 varieties of eicosanoid mediators that were detectable in human plasma and serum collected from healthy donors, using liquid chromatography-tandem mass spectrometry from the viewpoint of the clinical application of the multiplex quantitation of eicosanoid mediators. Wider variety of eicosanoid mediators were detected in serum (27 out of 30) than in plasma (14 out of 30), since the serum was thought to contain lipid mediators released from activated platelets...

BACKGROUND: The CDC's National Healthcare Safety Network's (NHSN) current risk adjustment model for surgical site infections (SSI) following open reduction internal fixation (ORIF) of long bone fractures is a suboptimal predictor of risk. We hypothesized that by including variables known to be associated with SSI following ORIF, we would develop a model that would increase the accuracy and predictability of SSI risk. METHODS: Patients who underwent ORIF of a long bone between January 1, 2012 and December 31, 2014 were included in the study (n=1543)...

The pelvis functions to transmit upper body loads to the lower limbs and is critical in human locomotion. Semi-automated, landmark-based finite element (FE) morphing and mapping techniques eliminate the need for segmentation and have shown to accelerate the generation of multiple specimen-specific pelvic FE models to enable the study of pelvic mechanical behaviour. The purpose of this research was to produce an experimentally validated cohort of specimen-specific FE models of the human pelvis and to use this cohort to analyze pelvic strain patterns during gait...

Given the central role of gluten in the pathogenesis of celiac disease (CD), a strict gluten-free diet (GFD) is the only validated treatment able to restore epithelium integrity and eliminate risks of complications. The risk of gluten contamination and the persistence of inflammation, even in patients strictly adhering to GFD, may render this treatment not always effective claiming the necessity of different new solutions. Oxidative and nitrosative stress have been indicated to play a pathophysiological role in CD...

PURPOSE: Anti-sperm antibodies (ASA) in men impair not only sperm motility but also fertilization and conception. However, utilization of corticosteroids to suppress ASA has shown variable pregnancy outcomes. This controversy is also extended to include the usefulness of conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in treatments of men with ASA. This study was therefore designed to define factors contributing to these inconsistent results. METHODS: Infertile men having ASA (n = 241) were randomly assigned for treatment with or without prednisolone for three cycles each of 21 days of their partner's menstrual cycles...

BACKGROUND: Early postoperative infection (EPI) following hardware placement in patients with malleolar fractures is a serious complication. Identifying factors that place patients at risk for early infection may help target interventions to prevent infections. METHODS: Data for the study included all adult patients who underwent operative management for closed malleolar fracture from 2006 to 2013 in the National Surgical Quality Improvement Program database. Characteristics of patients with and without EPI were compared using univariate tests...

Background and Aims: The incidence of childhood-onset (<18 years) inflammatory bowel disease is increasing worldwide, and some studies suggest that it represents a more severe disease phenotype. Few nationwide, population-based studies have evaluated the surgical burden in patients with childhood-onset IBD, and whether the improved medical treatment has influenced the need for gastrointestinal surgery. The aim was to examine whether the surgical treatment at any age of patients with childhood-onset IBD has changed over time...

Dehydroascorbate reductase (DHAR) is a key enzyme for glutathione (GSH)-dependent reduction of dehydroascorbate (DHA) to recycled ascorbate (AsA) in plants, and plays a major role against the toxicity of reactive oxygen species (ROS). Previously, we proposed that the increase of AsA regeneration via enhanced DHAR activity modulates the ascorbate-glutathione cycle activity against photooxidative stress in Chlamydomonas reinhardtii. In the present work, we use site-directed mutagenesis and crystal structure analysis to elucidate the molecular basis of how C...

Proximal femoral fractures in elderly patients represent a rapidly increasing socio-economic problem. The functional recovery and the mortality rate are influenced by a substantial quantity of variables, including the waiting time for surgical treatment ("time to surgery"). This study aims at investigating the average waiting time, and ascertaining the causes and effects, together with other non-modifiable variables, on the outcome for patients admitted to Milan's Istituto Ortopedico Gaetano Pini (Gaetano Pini Orthopaedic Institute) with a proximal femoral fracture...

Background Given the high incidence, prevalence and rate of recurrence, urolithiasis stone treatment at a high stone-free rate should have a low complication rate. The German S2k guideline (GS2k-GL) for the diagnostic testing, therapy and metaphylaxis of urolithiasis provides recommendations for the first and second choice for stone treatment, depending on stone location and size. Ureterorenoscopy (URS) is the treatment of first choice for most stones. URS is only the second option for renal stones > 20 mm and proximal ureteric stones ≤ 10 mm...

While object naming is traditionally considered asa left hemisphere function, neuroimaging studies have reported activations related to naming in the ventral temporal cortex (VTC) bilaterally. Our aim was to use intracerebral electrical stimulation to specifically compare left and right VTC in naming. In twenty-three epileptic patients tested for visual object naming during stimulation, the proportion of naming impairments was significantly higher in the left than in the right VTC (31.3% vs 13.6%). The highest proportions of positive naming sites were found in the left fusiform gyrus and occipito-temporal sulcus (47...

We studied the impact of HLA mismatching on the outcome of 318 consecutive patients who received an un-manipulated haploidentical bone marrow transplant, followed by post-transplant cyclophosphamide (PT-CY). The number of HLA mismatched antigens was tested for its impact on overall survival (OS) and non relapse mortality (NRM), whereas HLA mismatches in the graft versus host (GvH) direction were tested for prediction of GvHD and relapse; finally, we studied whether graft rejection correlated with the number of HLA mismatched antigens in host versus graft (HvG) direction...

INTRODUCTION: Growing evidence identifies adverse health effects for children who witness intimate partner violence at home. Research has also identified that women seeking elective pregnancy termination are at high risk for partner violence. However, little is known about the risk for violence exposure among the children of women seeking elective pregnancy termination. METHODS: We conducted a cross-sectional study of 957 women seeking elective pregnancy termination at a large family planning clinic...
