The chronic chikungunya arthritis symptoms closely mimic the rheumatoid arthritis (RA) symptoms, thus making it difficult to distinguish between these two clinical entities. The current comparative study characterizes NK (CD3(-)CD56(+)) and NK-like T (CD3(+)CD56(+)) cell responses in patients with chronic chikungunya arthritis and RA. Phenotype and functions of NK and NK-like T cells repertoire were assessed in 56 chronic chikungunya arthritis, 26 RA patients and 82 controls using flow cytometry. TNF-α and IFN-γ-secreting NK-like T cells were high in both chronic arthritis patients than in controls...

Despite relatively high manufacturing cost, crystalline-Si solar cell continues to hold promising future due to its high energy conversion efficiency and long life. As regards cost, one pertinent issue is the top electrode metallization of textured cell surface, which typically involves screen printing of silver paste. The associated disadvantages call for alternative methods that can lower the cost without compromising the solar cell efficiency. In the present work, a highly interconnected one dimensional (1D) metal wire network has been employed as front electrode on conventional Si wafers...

OBJECTIVE: Japanese encephalitis (JE) is a debilitating disease caused by infection with the JE virus (JEV; family: Flaviviridae), which leaves neurological sequelae in survivors but more often leads to mortality. Neurodegeneration caused by inflammation is the primary pathology behind the clinical manifestation of encephalitis caused by JEV. Bacillus Calmette-Guérin (BCG) has been used in immunoprophylaxis for tuberculosis and in the adjuvant therapy of many malignancies, and has exhibited neuroprotective activities in experimental models of Parkinson and Alzheimer disease...

The classical transmission disequilibrium test (TDT) based on a trio design uses information only on the allele transmitted by a heterozygous parent at a marker locus as homozygous parents are non-informative about linkage. However, the phenotype of an offspring depends on the alleles transmitted by both parents, irrespective of whether the parents are homozygous or heterozygous, and hence carry useful information on association. In this article, we propose modifications to the TDT procedures by incorporating transmission data on both parents in an informative trio to explore possible gain in power in detecting association...

BACKGROUND: There is a paucity of data regarding the microbial constituents of tobacco products and their impacts on public health. Moreover, there has been no comparative characterization performed on the bacterial microbiota associated with the addition of menthol, an additive that has been used by tobacco manufacturers for nearly a century. To address this knowledge gap, we conducted bacterial community profiling on tobacco from user- and custom-mentholated/non-mentholated cigarette pairs, as well as a commercially-mentholated product...

BACKGROUND AND AIMS: The transport of critically ill patients for procedures or imaging outside the Intensive Care Unit (ICU) is potentially hazardous; hence, the transport process must be organized and efficient. The literature about benefits of and untoward events (UEs) during intrahospital transport of pediatric critically ill patient is scarce. We, therefore, audited the UEs during and benefits of intrahospital transport of critically ill pediatric patients in our ICU. SUBJECTS AND METHODS: Eighty critically ill pediatric (<18 years) cancer patients, transported from the ICU for either diagnostic or therapeutic procedure over a period of 6 months, were included in the study...

A key component of both innate and adaptive immunity, new understandings of the complement system are expanding its roles beyond that traditionally appreciated. Evidence is accumulating that complement has an intracellular arsenal of components that provide not only immune defense, but also assist in key interactions for host cell functions. Although early work has primarily centered on T cells, the intracellular complement system likely functions in many if not most cells of the body. Some of these functions may trace their origins to the primitive complement system that began as a primeval form of C3 likely tasked for protection from intracellular pathogen invasion...

An intracellular complement system (ICS) has recently been described in immune and nonimmune human cells. This system can be activated in a convertase-independent manner from intracellular stores of the complement component C3. The source of these stores has not been rigorously investigated. In the present study, Western blotting identified a band corresponding to C3 in freshly isolated human peripheral blood cells that was absent in corresponding cell lines. One difference between native cells and cell lines was the time absent from a fluid-phase complement source; therefore, we hypothesized that loading C3 from plasma was a route of establishing intracellular C3 stores...

As the antibody-drug conjugate (ADC) field grows increasingly important for cancer treatment, it is vital for researchers to establish a firm understanding of how ADCs function at the molecular level. To gain insight into ADC uptake, trafficking, and catabolism-processes that are critical to ADC efficacy and toxicity-imaging studies have been performed with fluorophore-labeled conjugates. However, such labels may alter the properties and behavior of the ADC under investigation. As an alternative approach, we present here the development of a "clickable" ADC bearing an azide-functionalized linker-payload (LP) poised for "click" reaction with alkyne fluorophores; the azide group represents a significantly smaller structural perturbation to the LP than most fluorophores...

BACKGROUND: Non-muscle-invasive bladder cancer (NMIBC) is especially prevalent among the elderly. Many patients with NMIBC also have significant concomitant comorbidities, including cardiovascular diseases and hypercholesterolemia. Statins are the most commonly used cholesterol-depleting agents, and they may possess anticancer properties. The objective of this population-based study was to evaluate the effect of statins on the survival of individuals diagnosed with NMIBC. METHODS: This is a retrospective population-based cohort study that used administrative databases to identify individuals 66 years of age and older who were diagnosed with NMIBC between 1992 and 2012...

(68)Ga has great scope for use in future for positron emission tomography (PET) imaging due to its very fast blood clearance and fast target localization, even though at present (18)F is widely used. (68)Ge in equilibrium with (68)Ga ((68)Ge-(68)Ga) can also be used as a surrogate for (18)F calibration, as (18)F source standardization can be done at national metrology institute (NMI) but, these standards cannot be sent to nuclear medicine centers (NMCs) across India for calibration of isotope calibrators, due to the short half-life of (18)F (110min)...

The genes involved in menthol biosynthesis are reported earlier in Mentha × piperita. But the information on these genes is not available in Mentha arvensis. To bridge the gap in knowledge on differential biosynthesis of monoterpenes leading to compositional variation in the essential oil of these species, a comparative transcriptome analysis of the glandular trichome was carried out. In addition to the MVA and MEP pathway genes, about 210 and 196 different terpene synthases (TPS) transcripts were identified from annotation in M...
