Because of resistance development by cancer cells against current anticancer drugs, there is a considerable interest in developing novel antitumor agents. We have previously demonstrated that CIGB-552, a novel cell-penetrating synthetic peptide, was effective in reducing tumor size and increasing lifespan in tumor-bearing mice. Studies of protein-peptide interactions have shown that COMMD1 protein is a major mediator of CIGB-552 antitumor activity. Furthermore, a typical serine-protease degradation pattern for CIGB-552 in BALB/c mice serum was identified, yielding peptides which differ from CIGB-552 in size and physical properties...

PURPOSE: The conventional two-point (2pt) Dixon technique explicitly estimates B0 map by performing phase unwrapping. When signal loss, phase singularity, artifacts, or spatially isolated regions corrupt the measured phase images, this unwrapping-based technique will face difficulty. This work aims to improve the reliability of B0 mapping by performing unwrapping error correction. METHOD: To detect the unwrapping-caused phase errors, we determined a magnitude-based fat/water mask and used it as reference to identify pixels being mismatched by the phase-based mask, which was derived from the B0-corrected phase term of the Hermitian product between echoes...

Self-management plays a vital role in diabetes management for adults with type 2 diabetes (T2DM). While there are many people with T2DM in Vietnam, clinical understanding of diabetes self-management (DSM) in this context is limited due to the lack of a valid measurement instrument. Translation and back-translation processes were used to translate the Diabetes Self-Management Instrument (DSMI) into Vietnamese. Then, translation equivalence, face validity, construct validity, and internal consistency were assessed in a sample of 198 Vietnamese adults with T2DM...

BACKGROUND: Infectious mononucleosis (IM) is a clinical syndrome, usually caused by the Epstein Barr virus (EPV), characterised by lymphadenopathy, fever and sore throat. Most cases of symptomatic IM occur in older teenagers or young adults. Usually IM is a benign self-limiting illness and requires only symptomatic treatment. However, occasionally the disease course can be complicated or prolonged and lead to decreased productivity in terms of school or work. Antiviral medications have been used to treat IM, but the use of antivirals for IM is controversial...

PURPOSE: Active patient engagement is increasingly viewed as essential to ensuring that patient-driven perspectives are considered throughout the research process. However, guidance for patient engagement (PE) in HRQoL research does not exist, the evidence-base for practice is limited, and we know relatively little about underpinning values that can impact on PE practice. This is the first study to explore the values that should underpin PE in contemporary HRQoL research to help inform future good practice guidance...

Tumor endothelial marker 1 (TEM1) has been identified as a novel surface marker upregulated on the blood vessels and stroma in many solid tumors. We previously isolated a novel single-chain variable fragment (scFv) 78 against TEM1 from a yeast display scFv library. Here, we evaluated the potential applications of scFv78 as a tool for tumor molecular imaging, immunotoxin-based therapy and nanotherapy. Epitope mapping, three-dimensional structure docking and affinity measurements indicated that scFv78 could bind to both human and murine TEM1, with equivalent affinity, at a well-conserved conformational epitope...

BACKGROUND: When comparing clinical studies nationally and internationally, there is great heterogeneity in the applied audiometric outcome parameters. Beside different frequencies included in pure-tone audiometry and the resulting averages, the word recognition scores are measured at varying sound pressure levels, i.e., either with a fixed sound pressure level or with a fixed sensation level. However, a comparison of studies, e. g., in meta-analysis, requires comparable outcome parameters...

Human immunodeficiency virus type I (HIV-1) transactivator of transcription (TAT) is encoded by HIV-1. It is a peptide rich in basic amino acids and belongs to the protein transduction domain family. It has been found that HIV-1 TAT and its core peptide segment TAT47-57 play an important role in promoting the cellular uptake of coupled bioactive macromolecules, such as peptides, proteins, oligonucleotides, and drug molecules. HIV-1 TAT can also significantly increase the soluble expression of extrinsic proteins...

Fructose uptake in the soil bacterium Pseudomonas putida occurs through a canonical phosphoenolpyruvate (PEP)-dependent sugar transport system (PTS(Fru)). The logic of the genetic circuit that rules its functioning is puzzling: the transcription of the fruBKA operon, encoding all the components of PTS(Fru), can escape the repression exerted by the catabolite repressor/activator protein Cra solely in the presence of intracellular fructose-1-P, an agonist formed only when fructose has been already transported...

Our ability to decipher gene sequences has increased enormously with the advent of modern sequencing tools, but the ability to divulge functions of new genes have not increased correspondingly. This has caused a remarkable delay in functional interpretation of several newly found genes in tissue and age specific manner, limiting the pace of biological research. This is mainly due to lack of advancements in methodological tools for transgenesis. Predominantly practiced method of transgenesis by pronuclear DNA-microinjection is time consuming, tedious, and requires highly skilled persons for embryo-manipulation...

INTRODUCTION: Motor stereotypies represent a typical example of the difficulty in distinguishing non-clinical behaviors (physiological and transient) from symptoms or among different disorders ["primary stereotypies," associated with autistic spectrum disorder (ASD), intellectual disabilities, genetic syndromes, and sensory impairment]. The aim of this study was to obtain an accurate assessment on the relationship between stereotypies and neurodevelopmental disorders. METHODS: We studied 23 children (3 girls), aged 36-95 months, who requested a consultation due to the persistence or increased severity of motor stereotypies...

Introduction:Acinetobacter baumannii is a nosocomial pathogen that usually affects critically ill patients. High mortality rates have been associated with MDR A. baumannii infections. Carbapenem resistance among these isolates is increasing worldwide and is associated with certain International Clones (ICs) and oxacillinases (OXAs). Moreover, this organism possesses a wide range of virulence factors, whose expression is not yet fully understood. In this study, clinical A. baumannii isolates are characterized in terms of antibiotic resistance, mechanisms of carbapenem resistance, clonality, and virulence...
