BACKGROUND: Cognitive impairment is common in kidney transplant (KT) recipients and affects quality of life, graft survival, morbidity, and mortality. Failure to identify patients with cognitive impairment can withhold appropriate and timely intervention. This study determines whether measured cognition with standard screening tools offers any advantage over perceived cognition in screening transplant patients for cognitive impairment. METHODS: Cognition was assessed in 157 KT recipients using the Montreal Cognitive Assessment (MoCA; measured cognition)...

Polymorphonuclear neutrophils (PMNn) are the pivotal mediators of phagocytosis. In addition to neutropenia, impaired neutrophilic function is associated with pathological conditions and immuno-deficiencies. Henceforth, Immuno-stimulatory strategies targeting neutrophilic function are indeed powerful tools in combating obstinate infections. In appreciation towards the usefulness of herbal medicines in therapeutic scenario, the present study was carried out to analyse the immuno-stimulatory effect of Cuscuta epithymum, Ipomoea batata and Euphorbia hirta using in-vitro and in-vivo rodent experimental models...

We developed a smartphone app-based monitoring tool for the detection of anionic surfactants (AS), including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Akin to the methylene blue active substances (MBAS), liquid-phase extraction (LPE) is employed to extract the hydrophobic ion-pair of dye (ethyl violet)-AS to an organic phase (ethyl acetate). The colour (RGB) of the organic phase is read using a smartphone camera with the help of a reading kit. The value of RGB is carefully corrected and linked to the concentration of ASs with a standard deviation of <10% in the 10-1000 ppb (part per billion) range...

Leucine aminopeptidase (LAP) is a kind of proteolytic enzymes and associated closely with pathogenesis of cancer and liver injury. Accurate detection of LAP activity with high sensitivity and selectivity is imperative to detect its distribution and dynamic changes for understanding LAP's function and early diagnosing the disease states. However, fluorescent detection of LAP in living systems is challenging. To data, rarely fluorescent probes have been reported for imaging LAP in vivo. In this study, a novel probe (TMN-Leu) was developed by conjugating a near-infrared dicyanoisophorone derivative fluorophore with LAP activatable L-leucine amide moiety for the first time...

Glioblastoma (GBM), which is characterised by rapid growth, cellular heterogeneity, angiogenesis, extensive invasion, hypoxia and necrosis, is the most common histological subtype of glioma in adults. MicroRNA (miRNA) dysregulation is a common feature of human cancers, including GBM. Previous studies have suggested that miRNAs are a novel class of regulatory molecules in various human cancers. Therefore, miRNAs may be investigated as a novel candidate and screening tool in the clinical diagnosis, therapy and prognosis of GBM...

Summary: Microsatellites are found to be related with various diseases and widely used in population genetics as genetic markers. However, it remains a challenge to identify microsatellite from large genome and screen microsatellites for primer design from a huge result dataset. Here, we present Krait, a robust and flexible tool for fast investigation of microsatellites in DNA sequences. Krait is designed to identify all types of perfect or imperfect microsatellites on a whole genomic sequence, and is also applicable to identification of compound microsatellites...

Background: Efficient viral load testing is needed for hepatitis C (HCV) surveillance and diagnosis. HCV viral load testing using dried blood spots (DBSs), made with a single drop of finger-prick whole blood on filter paper, is a promising alternative to traditional serum- or plasma-based approaches. Methods: We adapted the Abbott Molecular m2000 instrument for high-throughput HCV viremia testing using DBSs with simple specimen processing and applied these methods to estimate the national burden of infection in the Democratic Republic of the Congo (DRC)...

Despite reductions in cigarette smoking in the United States, approximately 40 million Americans are smokers. Innovative interventions are needed to help remaining smokers quit. To develop innovative interventions, precise and effective tools are needed. Here, a laboratory model of smoking relapse is assessed for its ability to detect increased resistance to smoking across 2 interventions and for its sensitivity to differing degrees of effectiveness. Nicotine-deprived participants (N = 36) completed, in randomized order, 4 smoking resistance sessions with and without implementation intentions and monetary incentives...

Porous media made of nitrocellulose and glass fiber are common "paper" substrates for lateral flow assays, microfluidic paper analytical devices, and other point-of-care diagnostic assays. Such assays commonly use optical labels such as gold nanoparticles, latex beads, or fluorescent nanoparticles to visualize the presence of analytes. Fluorescent labels are commonly used in bioassays to enhance sensitivity, but autoluminescence of the paper substrate worsens signal-to-noise ratios of fluorescence-based assays...

This work presents an educational simulation to support students' learning about the formation of the rainbow. The main aim of the simulation is to provide our students with a didactic tool in addition to their traditional laboratory practice, which can be easily implemented in e-learning teaching platforms. A system consisting of a flask filled with water and a screen with a rounded aperture placed between the sun and the flask was simulated; this way a faint rainbow was seen on the simulated screen. The interactive nature of the simulation allowed the students to perform some alterations that would be impossible to do in the real world; thus, the observed rainbow deviated from the simplest model...

Trabecular bone score, an index of lumbar spine trabecular texture, has not been explored fully in adolescent girls. Our cross-sectional analysis supported the hypothesis that "adult normal" trabecular bone score has been achieved by the end of the first year post-menarche, providing a potential screening tool, independent from bone density. INTRODUCTION: Trabecular bone score (TBS) evaluates lumbar spine (LS) trabecular texture from DXA images. Limited evidence suggests low TBS in pre-pubertal girls...

Evolve and resequence experiments have provided us a tool to understand bacterial adaptation to antibiotics. In our previous work, we had used short term evolution to isolate mutants resistant to the ribosome targeting antibiotic kanamycin, and reported that Escherichia coli develops low cost resistance to kanamycin via  different point mutations in the translation Elongation Factor-G (EF-G). Furthermore, we had shown that the resistance of EF-G mutants could be increased by second site mutations in the genes rpoD / cpxA / topA / cyaA Mutations in three of these genes had been discovered in earlier screens for aminoglycoside resistance...

The electrocardiogram (ECG) is a relatively insensitive tool for the detection of right ventricular hypertrophy (RVH), but some criteria have high specificity. The recommended ECG screening criteria for RVH are not sufficiently sensitive or specific for screening for mild RVH in adults without clinical cardiovascular disease. The greatest accuracy of the ECG is in congenital heart disease, with intermediate accuracy in acquired heart disease and primary pulmonary hypertension in adults.

BACKGROUND: Extensive osteochondritis dissecans (OCD) lesions of the lateral ridge of the trochlea of the femur (LRTF), the most common OCD- affected site in the stifle, have a poor outcome with surgical debridement and can be career ending. The early detection of osteochondrosis lesions and their conservative management holds the promise to enhance outcome. We hypothesise that ultrasonography is a valuable field screening tool to detect and monitor early subclinical LRTF osteochondrosis...

INTRODUCTION: Several studies have found cognitive impairment in patients with a history of alcohol use disorder, affecting their psychosocial functioning and the achievement of therapeutic goals. In order to identify these effects, several cognitive screening tests have been used, though they were not specific for alcoholic population, possibly leading to an increase in the risk of error. OBJECTIVE: The aim of this study is to assess the main cognitive deficits in patients with history of alcohol use disorders, through the development of a specific screening test for alcohol-related cognitive impairment...
