Isabella Karlsson, Lorena Ndreu, Alessandro Quaranta, Gunnar Thorsén
A method we previously developed has been applied to the determination of the glycosylation pattern of specific proteins in biological samples. Six proteins (alpha-1-antitrypsin, transferrin, haptoglobin, C1 inhibitor, alpha-1 acid glycoprotein, and immunoglobulin G) were studied in serum samples from five individuals and cerebrospinal fluid (CSF) samples from three individuals, to investigate the expected normal distribution of glycosylation patterns and to assess whether this methodology can be used to discriminate between samples from different individuals...

A sensitive and rapid LC-MS/MS method was developed and validated for the quantification of SUVN-502 and M1 of SUVN-502, a 5-HT6 receptor antagonist for the treatment of dementia associated with Alzheimer's disease. Following solid-phase extraction, SUVN-502 and M1 of SUVN-502 and IS were eluted with 10mM ammonium acetate (pH 4.0) and acetonitrile using a rapid gradient program on reverse phase column. Multiple reaction monitoring mode was used to monitor the respective transitions of m/z 478.2→377.7 for SUVN-502 and m/z 464...

Nabanita Basu, Samir Kumar Bandyopadhyay
It is often difficult to predict the sex of an individual based on bloody incomplete footprints. However, such prints/impressions are particularly common in a crime scene. Again variability in the texture, color of the target surface has an impact on the bloodstained impression formed. The study of bare foot, footprint, footwear (i.e. shoe, canvas etc.) within the legal context is referred to as forensic podiatry. Based on the fact that it is possible to predict the sex of an individual from footprint impressions, an automated model has been proposed in this paper for analyzing the sex of an individual from his/her broken/incomplete footprint impressions based on morphological features alone...

Africa's economy is growing faster than any other continent and it has been estimated that the middle class in Africa now exceeds 350 million people. This has meant a parallel increase in the importation of consumer goods and in the implementation of communication and information technologies (ICT), but also in the generation of large quantities of e-waste. However, inadequate infrastructure development remains a major constraint to the continent's economic growth and these highly toxic residues are not always adequately managed...

High failure rates of Peripheral Arterial Disease (PAD) stenting appear to be associated with the inability of certain stent designs to accommodate severe biomechanical environment of the femoropopliteal artery (FPA) that bends, twists, and axially compresses during limb flexion. Twelve Nitinol stents (Absolute Pro, Supera, Lifestent, Innova, Zilver, Smart Control, Smart Flex, EverFlex, Viabahn, Tigris, Misago, and Complete SE) were quasi-statically tested under bench-top axial and radial compression, axial tension, bending, and torsional deformations...

Molecular topology was used to develop a mathematical model capable of classifying compounds according to antimicrobial activity against methicillin resistant Staphylococcus aureus (MRSA). Topological indices were used as structural descriptors and their relation to antimicrobial activity was determined by using linear discriminant analysis. This topological model establishes new structure activity relationships which show that the presence of cyclopropyl, chlorine and ramification pairs at a distance of two bonds favor this activity, while the presence of tertiary amines decreases it...

Oxidative stress is considered a central pathophysiological event in cardiovascular disease, including hypertension. Early age reduction in renal mass is associated with hypertension and oxidative stress in later life, which is aggravated by increased salt intake. The aim of the present study was to examine if renal sympathetic denervation can exert blood pressure lowering effects in uninephrectomized (UNX) rats (3-week old) fed with high salt (HS, 4%; w/w) diet for 4 weeks. Moreover, we investigated if renal denervation is associated with changes in NADPH and xanthine oxidase-derived reactive oxygen species...

The neurodevelopment and functioning of the central nervous system, and especially the cerebral cortex, have basic importance to understand neuropsychiatric disorders like autism. Fibroblast growth factor-2 (FGF-2) plays a very important role in the development and functioning of the cortex. FGF-2 is related to developmental processes in the central nervous system such as neurogenesis, migration, differentiation and survival. This study researched the serum FGF-2 levels in children with autism spectrum disorder (ASD)...

Jinsong Zhao, Run Zhang
Species sensitivity distribution (SSD) model is often used to extrapolate the chemicals' effects from the ecotoxicological data on individual species to ecosystems, and is widely applied to derive water quality criteria or to assess ecological risk. Because of the influence of various factors, the ecotoxicological data of a specific chemicals to an individual usually exist in a range. The feasibility of interval ecotoxicological data directly applied to build SSD model has not been clearly stated. In the present study, by means of Bayesian statistics, the half maximal effective concentration (EC50) of pentachlorophenol (PCP) to 161 aquatic organisms, which were organized into 7 groups, i...

Mycobacterium tuberculosis (Mtb), had developed evolutionary changes in its genome to adapt for survival and thereby generated multi-drug resistant strains. However, novel drug targets that remained unchanged for their biochemical role has impressed the research community to target such proteins. The comprehensive analysis of multiple protein targets has influenced us to make a consensus structural rule exploited by pharmacophore and other allied techniques from a large repository of protein structures. In this pursuit, we made a retrospective analysis of pharmacophores mapped from the tuberculosis structural proteome and identified unique patterns that can be employed for the novel molecules design...

Adaptive management is an experimental approach used by water management agencies around the world to manage and restore aquatic ecosystems. The effectiveness of the approach can often be constrained by inflexible institutional arrangements. In this paper we compare two cases where agencies have implemented adaptive management to manage and restore aquatic ecosystems. Our aim was to understand practitioners' perceptions of how institutional flexibility can be created for adaptive management. We interviewed 14 adaptive management practitioners working in the Murray-Darling Basin, Australia and 14 practitioners in Southern Florida, United States of America...

Children residing in long-term out-of-home care have high rates of clinical-level mental health difficulties. However, the stability of these children's difficulties throughout their time in care is uncertain. This paper reports estimates of the seven- to nine-year stability of carer-reported scores on the Child Behavior Checklist (CBCL) and Assessment Checklists for Children (ACC) and Adolescents (ACA) for 85 children in long-term foster or kinship care. Prospective score changes on the CBCL total problems and ACC-ACA shared-item scales were assigned to one of four change groups: 'sustained mental health'; 'meaningful improvement'; 'no meaningful change'; and 'meaningful deterioration'...

Severe epilepsy in children and young adults can significantly affect the lives of their caregivers. However, the lack of a reliable and valid measure of caregiver impact has limited our understanding of the scope and correlates of this impact, as well as our ability to measure the effects of treatments that could lessen it. The purpose of this study was to facilitate focus groups and interviews with an international group of clinician experts and caregivers to identify the most important domains that should be assessed in a measure of caregiver impact...

INTRODUCTION: [(18)F]Fluoromethylcholine ([(18)F]FCH) is a potent tumors imaging agent. In order to fulfill the demand of pre-clinical and clinical studies, we have developed an automated high yield one-pot synthesis of this potent tumors imaging agent. METHODS: [(18)F]FCH was synthesized using a modified TRACERlab FxFN module. Briefly, dibromomethane (10% in CH3CN) was fluorinated with K[(18)F]/K 2.2.2 in a glassy carbon reaction vessel at 120°C for about 5min to generate [(18)F]fluorobromomethane ([(18)F]FBM)...

INTRODUCTION: Despite important advances of longitudinal research in substance use behaviors, most studies stratify analyses by gender or race, which limits the ability to directly compare the likelihood of a particular developmental pathway across demographic groups. Thus, there is critical need for well-designed research to examine the associations of race/ethnicity with developmental trajectories of substance use behaviors across adolescence through adulthood. METHODS: Using an accelerated longitudinal design, we examined behaviors across ages 12-31 from Waves I-IV of the National Longitudinal Study of Adolescent to Adult Health...

Our study aims at the creation of a numerical toolbox that describes wave propagation in samples containing internal contacts (e.g. cracks, delaminations, debondings, imperfect intergranular joints) of known geometry with postulated contact interaction laws including friction. The code consists of two entities: the contact model and the solid mechanics module. Part I of the paper concerns an in-depth description of a constitutive model for realistic contacts or cracks that takes into account the roughness of the contact faces and the associated effects of friction and hysteresis...

INTRODUCTION: Primary small cell neuroendocrine carcinoma of the breast (SCNCB) is a very uncommon type of breast cancer. Histology and morphology are virtually indistinguishable from small cell neuroendocrine carcinomas of the lung (SCNCL), mandating a search for a primary site elsewhere in the body. There is no standard approach to treatment as there are only a limited number of cases reported in the literature. This report summarizes a case of primary SCNCB and presents a review of the literature...

This paper discusses the use of Nominal Group Technique (NGT) for European nursing exchange evaluation at one university. The NGT is a semi-quantitative evaluation method derived from the Delphi method popular in the 1970s and 1980s. The NGT was modified from the traditional version retaining the structured cycles and but adding a broader group discussion. The NGT had been used for 2 successive years but required analysis and evaluation itself for credibility and 'fit' for purpose which is presented here. It aimed to explore nursing students' exchange experiences and aid programme development futures exchanges and closure from exchange...
