Anish Kumar, V Shanthi, K Ramanathan
Crizotinib is an anticancer drug used for the treatment of non-small cell lung cancer. Evidences available suggest that there is a development of an acquired resistance against crizotinib action due to the emergence of several mutations in the ALK gene. It is therefore necessary to develop potent anti-cancer drugs for the treatment of crizotinib resistance non-small cell lung cancer types. In the present study, a novel class of lead molecule was identified using virtual screening, molecular docking and molecular dynamic approach...

INTRODUCTION: Acetone cyanohydrin (ACH) is a toxic substance present in cassava roots (Manihot esculenta Crantz) which results from enzymatic hydrolysis of linamarin. Long-term consumption is associated with 2 neurological disorders: konzo and tropical ataxic neuropathy. Previous studies have evaluated behavioural alterations linked to ACH consumption, but the toxic effects of this substance on physiological processes remain unknown. METHOD: 32 male Wistar rats were assigned to 4 experimental groups (n=8 per group): a vehicle group (0...

OBJECTIVES: The screening of latent tuberculosis infection (LTBI) is necessary to prevent infection in patients with chronic inflammatory disease (CID) undergoing biological treatment. We aimed to assess the efficacy of LTBI screening prior to biological treatment in Tunisia, considered as a high-incidence area of active TB disease. METHODS: We conducted a retrospective study over a period of 8 years [2007-2014] including patients with chronic inflammatory rheumatism receiving biologic agents since at least 6 months...

N-terminal derivatization of peptides with the chromogenic reagent 4-acetamido-4-isothiocyanatostilbene-2,2-disulfonic acid (SITS) is demonstrated to enhance the efficiency of 266 nm ultraviolet photodissociation (UVPD). Attachment of the chromophore results in a mass shift of 454 Da and provides significant gains in the number and abundances of diagnostic fragment ions upon UVPD. Activation of SITS-tagged peptides with 266 nm UVPD leads to many fragment ions akin to the a/b/y ions commonly produced by CID, along with other sequence ions (c, x, and z) typically accessed through higher energy pathways...

Metallic nanoparticles show extraordinary strong light absorption near their plasmon resonance, orders of magnitude larger compared to nonmetallic nanoparticles. This "antenna" effect has recently been exploited to transfer electrons into empty states of an attached material, for example to create electric currents in photovoltaic devices or to induce chemical reactions. It is generally assumed that plasmons decay into hot electrons, which then transfer to the attached material. Ultrafast electron-electron scattering reduces the lifetime of hot electrons drastically in metals and therefore strongly limits the efficiency of plasmon induced hot electron transfer...

RATIONALE: Qualitative data analysis of glycomic MS/MS data based on m/z values of product ions alone is widely used, and often sufficient for analysis of single analytes. However, most complex glycomic mixtures contain multiple isobaric oligosaccharides, in which case this approach is often limited. Here we show how ion intensity information can be used in order to enhance MS/MS data analysis, and extract both qualitative and semiquantitative information from complex glycomic MS/MS datasets...

Muscle tone is regulated across sleep-wake states, being maximal in waking, reduced in slow wave sleep (SWS) and absent in paradoxical or REM sleep (PS or REMS). Such changes in tone have been recorded in the masseter muscles and shown to correspond to changes in activity and polarization of the trigeminal motor 5 (Mo5) neurons. The muscle hypotonia and atonia during sleep depend in part on GABA acting upon both GABAA and GABAB receptors (Rs) and acetylcholine (ACh) acting upon muscarinic 2 (AChM2) Rs. Here, we examined whether Mo5 neurons undergo homeostatic regulation through changes in these inhibitory receptors following prolonged activity with enforced waking...

The realization of micromotors able to dock and transport microscopic objects in a fluid medium has direct applications toward the delivery of drugs and chemicals in small channels and pores, and the realization of functional wireless microrobots in lab-on-a-chip technology. A simple and general method to tow microscopic particles in water by using remotely controllable light-activated hematite microdockers is demonstrated. These anisotropic ferromagnetic particles can be synthesized in bulk and present the remarkable ability to be activated by light while independently manipulated via external fields...

The over 500 human protein kinases are estimated to phosphorylate at least one-third of the proteome. This posttranslational modification is of paramount importance to intracellular signaling and its deregulation is linked to numerous diseases. Deciphering the specific cellular role of a protein kinase of interest remains challenging given their structural similarity and potentially overlapping activity. In order to exert control over the activity of user-defined kinases and allow for understanding and engineering of complex signal transduction pathways, we have designed ligand inducible split protein kinases...

The antiandrogens, such as bicalutamide, targeting the androgen receptor (AR), are the main endocrine therapies for prostate cancer (PCa). But as drug resistance to antiandrogens emerges in advanced PCa, there presents a high medical need for exploitation of novel AR antagonists. In this work, the relationships between the molecular structures and antiandrogenic activities of a series of 7α-substituted dihydrotestosterone derivatives were investigated. The proposed MLR model obtained high predictive ability...

H E Cid, G Carrasco-Núñez, V C Manea
Petrophysical analysis using X-ray microtomography provides key textural and compositional information, useful to investigate porous media characteristics of hydrocarbon and geothermal reservoirs. Several approaches, used for rock porosity estimation from tomography data, rely mainly on visual or mathematical segmentation algorithms that attempt to obtain thresholding values to segment a phase solved by pixel analysis resolution. Therefore, porosity is evaluated using only pores above pixel resolution (macroporosity), and dismiss pores sized less than the pixel resolution (microporosity) that can be essential to characterize permeability conditions of geothermal reservoirs...

Exploring the function of interleukin (IL) 17 and related cytokine interactions have been proven useful toward understanding the role of inflammation in autoimmune diseases. Production of the inflammatory cytokine IL-23 by dendritic cells (DC's) has been shown to promote IL-17 expression by Th17 cells. It is well established that Th17 cells play an important role in several autoimmune diseases including psoriasis and alopecia. Our recent investigations have suggested that Kynurenine-rich environment can shift a pro-inflammatory response to an anti-inflammatory response, as is the case in the presence of the enzyme Indoleamine 2,3 dioxygenase (IDO), the rate-limiting enzyme in tryptophan degradation and Kynurenine (Kyn) production...

Since hepatitis A virus (HAV) production is time-consuming and expensive, the use of recombinant proteins may represent an alternative source of antigens for diagnostic purposes. The present study aimed to express, purify and evaluate the potential of recombinant VP1 protein (rVP1) as a marker for the diagnosis of acute HAV infection. The rVP1 was expressed and purified successfully from Escherichia coli. The purified rVP1 was used to establish an in-house enzyme-linked immunosorbent assay (ELISA-rVP1) for detection of IgM antibodies in sera from HAV-positive patients...

A search for the B^{0}→K^{+}K^{-} decay is performed using pp-collision data collected by LHCb. The data set corresponds to integrated luminosities of 1.0 and 2.0  fb^{-1} at center-of-mass energies of 7 and 8 TeV, respectively. This decay is observed for the first time, with a significance of more than 5 standard deviations. The analysis also results in an improved measurement of the branching fraction for the B_{s}^{0}→π^{+}π^{-} decay. The measured branching fractions are B(B^{0}→K^{+}K^{-})=(7...

Giant cell arteritis (GCA) and Takayasu's arteritis (TAK) are major forms of large-vessel vasculitis (LVV) that share clinical features. To evaluate their genetic similarities, we analysed Immunochip genotyping data from 1,434 LVV patients and 3,814 unaffected controls. Genetic pleiotropy was also estimated. The HLA region harboured the main disease-specific associations. GCA was mostly associated with class II genes (HLA-DRB1/HLA-DQA1) whereas TAK was mostly associated with class I genes (HLA-B/MICA). Both the statistical significance and effect size of the HLA signals were considerably reduced in the cross-disease meta-analysis in comparison with the analysis of GCA and TAK separately...

The molecular fingerprinting of intact fruit samples combined with statistical data analysis can allow the assessment of fruit quality and location of origin. Herein, microwave plasma torch desorption ionization mass spectrometry (MPT-MS) was applied to produce molecular fingerprints for the juice sac and exocarp of navel oranges cultivated in three closely located habitats, and the mass spectrometric fingerprints were differentiated by principal component analysis (PCA). Because of the relatively high temperature and high ionization efficiency of MPT, the volatile aroma compounds and semivolatile chemicals in the navel oranges were sensitively detected and confidently identified by collision induced dissociation (CID)...
