C-reactive protein (CRP) is an evolutionarily conserved protein, a component of the innate immune system, and an acute phase protein in humans. In addition to its raised level in blood in inflammatory states, CRP is also localized at sites of inflammation including atherosclerotic lesions, arthritic joints and amyloid plaque deposits. Results of in vivo experiments in animal models of inflammatory diseases indicate that CRP is an anti-pneumococcal, anti-atherosclerotic, anti-arthritic and an anti-amyloidogenic molecule...

BACKGROUND: Influenza virus spreads infection by two main surface glycoproteins, namely hemagglutinin (HA) and neuraminidase (NA). NA cleaves the sialic acid receptors eventually releasing newly formed virus particles which then invade new cells. Inhibition of NA could limit the replication of virus to one round which is insufficient to cause the disease. RESULTS: An experimentally reported series of acylguanidine zanamivir derivatives was used to develop GQSAR model targeting NA in different strains of influenza virus, H1N1 and H3N2...

Nucleotide-binding oligomerization domain (NOD)-like receptor 2 is one of the important mediators of innate as well as adaptive immune response to microbial infections. In this study, NOD-like receptor-2 was characterized by determining the full gene sequence and analyzing genetic diversity in Indian buffaloes. Sequence analysis of buffalo NOD2 revealed 3042 nucleotides long ORF, encoding 1013 amino acids from 12 exons. Domain structure analysis indicated existence of 8 leucine-rich repeat (LRR) domains in buffalo, cattle, sheep and mouse, along with central NACHT/NOD domain and two N-terminal CARD domains...

Graft-versus-host disease remains a major cause of transplant-related mortality. Interleukin-2 plus sirolimus synergistically reduces acute graft-versus-host disease in rodents and promotes regulatory T-cells. This phase II trial tested the hypothesis that interleukin-2 would facilitate STAT5 phosphorylation in donor T-cells, expand regulatory T-cells, and ameliorate graft-versus-host disease. Between 4/16/2014-12/19/2015, 20 patients received interleukin-2 (200,000IU/m2 thrice weekly, days 0 to +90) with sirolimus (5-14ng/ml) and tacrolimus (3-7ng/ml) after HLA-matched related or unrelated allogeneic hematopoietic cell transplantation...

C-reactive protein (CRP) is present at sites of inflammation including amyloid plaques, atherosclerotic lesions and arthritic joints. CRP, in its native pentameric structural conformation, binds to cells and molecules which have exposed phosphocholine (PCh) groups. CRP, in its non-native pentameric structural conformation, binds to a variety of deposited, denatured and aggregated proteins, in addition to binding to PCh-containing substances. In this study, we investigated the effects of hydrogen peroxide (H2O2), a prototypical reactive oxygen species and which is also present at sites of inflammation, on the ligand recognition function of CRP...

Nano-encapsulation of several natural products has become an important tool in enhancing the bioavailability of some modern drugs against many diseases. Pelargonidin is an anthocyanidin found in many fruits and vegetables. Pelargonidin is loaded with poly-lactide-co-glycolic-acid, a non-toxic biodegradable polymer, to produce nano-pelargonidin. Size, morphology, zeta potential, and planar uniformity of formulated nano-pelargonidin were determined by atomic force microscopy and dynamic light scattering. The time required for cellular entry, folds of nano-pelargonidin, and drug encapsulation efficiency of poly-lactide-co-glycolic-acid were also ascertained...

BACKGROUND: Breast cancer is the most common cancer diagnosed among women and is the second leading cause of cancer death. Homeopathic medicines are part of the alternative medicines that are given as a supportive therapy in breast cancer. The objective of this study was to investigate the anticancer activity of commercially available homeopathic preparations of Terminalia chebula (TC) and evaluate their nanoparticulate nature. METHODS: Mother tincture (MT) and other homeopathic preparations (3X, 6C and 30C) of TC were tested for their effect on the viability of breast cancer (MDAMB231 and MCF7) and non-cancerous (HEK 293) cell lines by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay...

Cardiac hypertrophic growth in response to pathological cues is associated with reexpression of fetal genes and decreased cardiac function and is often a precursor to heart failure. In contrast, physiologically induced hypertrophy is adaptive, resulting in improved cardiac function. The processes that selectively induce these hypertrophic states are poorly understood. Here, we have profiled 2 repressive epigenetic marks, H3K9me2 and H3K27me3, which are involved in stable cellular differentiation, specifically in cardiomyocytes from physiologically and pathologically hypertrophied rat hearts, and correlated these marks with their associated transcriptomes...

The electronic structure and reactivity of iron porphyrin complexes bearing 2(nd) sphere hydrogen bonding residues have been investigated over the last few years. The presence of these weak interactions alters the spin ground state, and axial ligand bonding and provides a proton translocation pathway into the active site. Mechanistic investigations in organic as well as aqueous media demonstrate how controlled delivery of protons is fundamental in dictating the selectivity of a multi-electron multi-proton process like the reduction of dioxygen to water...

The acquisition of multidrug resistance in bacteria has become a bigger threat of late, mainly due to the bacterial signaling phenomenon, quorum sensing (QS). QS, among a population of bacteria, initiates the formation of biofilms and offers myriad advantages to bacteria. Burgeoning antibiotic resistance in biofilm-producing bacteria has motivated efforts toward finding new alternatives to these traditional antimicrobials. In the present study, we report the increased solubility and additional quorum quenching as well as biofilm disruption activity of glyco-derivatives of monoterpenes (citral and citronellal)...

Deregulated IGF-1R-AKT signaling influences multiple nodes of cancer cell physiology and assists in migration, metastasis and acquirement of radio/chemoresistance. Enrichment of cancer stem cells (CSC) positively correlates with radio/chemoresistance development in various malignancies. It is unclear though, how IGF-1R-AKT signalling shapes CSC functionality especially in ovarian cancer. Previously we showed that upregulated IGF-1R expression is essential to initiate platinum-taxol resistance at early stage which declines with elevated levels of activated AKT at late resistant stage in ovarian cancer cells...

The conventional drugs used for the treatment of human visceral leishmaniasis have concerns about the toxicity and most importantly parasite resistance. To overcome these troubles, more efforts are made for the development of innovative therapeutic agents having effective antileishmanial activity and simultaneously stimulate adaptive immune system of host cells. Hence, search for new leishmanicidal from the natural origin like plants has shown its effectiveness for the treatment of this tropical disease. The aim of this study is to investigate and characterize the antileishmanial efficacy of Coccinia grandis (L...

Mammalian cytochrome c (Cytc) plays a key role in cellular life and death decisions, functioning as an electron carrier in the electron transport chain and as a trigger of apoptosis when released from the mitochondria. However, its regulation is not well understood. We show that the major fraction of Cytc isolated from kidneys is phosphorylated on Thr(28), leading to a partial inhibition of respiration in the reaction with cytochrome c oxidase. To further study the effect of Cytc phosphorylation in vitro, we generated T28E phosphomimetic Cytc, revealing superior behavior regarding protein stability and its ability to degrade reactive oxygen species compared with wild-type unphosphorylated Cytc Introduction of T28E phosphomimetic Cytc into Cytc knock-out cells shows that intact cell respiration, mitochondrial membrane potential (ΔΨm), and ROS levels are reduced compared with wild type...

Mechanical unfolding studies on Ribonucleic Acid (RNA) structures are a subject of tremendous interest as they shed light on the principles of higher order assembly of these structures. Pseudoknotting is one of the most elementary ways in which this higher order assembly is achieved as discrete secondary structural units in RNA are brought in close proximity to form a tertiary structure. Using steered molecular dynamics (SMD) simulations, we have studied the unfolding of five RNA pseudoknot structures that differ from each other either by base substitutions in helices or loops...

It is unclear if persistent splenomegaly in the presence of a negative positron emission tomography (PET) scan before allogeneic hematopoietic cell transplantation (HCT) influences post-transplantation outcomes in patients with lymphoma. We retrospectively reviewed records of 152 patients who underwent allogeneic HCT for various lymphomas. Centralized review of pretransplantation computed tomography (CT) and PET images was performed. Spleen volume (SV) was measured using the freehand volume segmentation tool in AW Workstation software (General Electric, Waukesha, WI)...
