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...

AIMS: While New Zealand has experienced an increase in the use of traditional Chinese medicine (TCM) based acupuncture, very little is known about the practitioners who provide this type of treatment modality. Therefore, this study was designed to identify differences associated with being a TCM practitioner in New Zealand compared to China. METHODS: Ten Auckland-based TCM practitioners were individually interviewed. The interview schedule comprised of questions that were designed to identify any potential differences in practising TCM in New Zealand compared to China...

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 (ETC) 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 Thr28, 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 Thr28Glu phosphomimetic Cytc, revealing superior behavior regarding protein stability and its ability to degrade reactive oxygen species compared to wild-type unphosphorylated Cytc...

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)...

BACKGROUND: For patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), autologous hematopoietic cell transplantation (auto-HCT) is commonly used. After auto-HCT, DLBCL patients are often monitored with surveillance imaging. However, there is little evidence to support this practice. PATIENTS AND METHODS: We performed a multicenter retrospective study of DLBCL patients who underwent auto-HCT (n = 160), who experienced complete remission after transplantation, and who then underwent surveillance imaging...

Silk fibroin (SF) protein, produced by silkworm Bombyx mori, is a promising biomaterial, while sophorolipid (SL) is an amphiphilic functional biosurfactant synthesized by nonpathogenic yeast Candida bombicola. SL is a mixture of two forms, acidic (ASL) and lactonic (LSL), which when added to SF results in accelerated gelation of silk fibroin. LSL is known to have multiple biological functionalities and hence hydrogels of these green molecules have promising applications in the biomedical sector. In this work, SANS, NMR, and rheology are employed to examine the assembling properties of individual and mixed SLs and their interactions with SF to understand the mechanism that leads to rapid gelation...

Histones are associated with DNA to form nucleosome essential for chromatin structure and major nuclear processes like gene regulation and expression. Histones consist of H1, H2A, H2B and H3, H4 type proteins. In the present study combined histones from calf thymus were complexed with ct DNA and their binding affinities were measured fluorimetrically. All the five histones were resolved on SDS page and their binding with DNA was visualised. The values of biding affinities varied with pH and salt concentration...

Phosphate groups chemically grafted onto polymer substrates can be used as biomimetic analogs for in vitro studying of function of biomacromolecules and also as tissue substitutes in clinical conditions of organ loss. Despite this inspiration, studies correlating effect of degree of phosphate grafting of a polymer on fabrication and biological properties of polymers are lacking. In this work, N-methylene phosphonic chitosan (PC) with different degrees of phosphate contents were synthesized and the effect of phosphate grafting on electrospinning behavior of substituted polymers is investigated...

Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative option for patients with myelodysplastic syndrome (MDS). Because MDS predominantly affects an older population, age-associated comorbidities can preclude patients from cure. HSCT is associated with the risk of morbidity and mortality; however, with safer conditioning regimens and improved supportive care, eligible patients with an appropriately matched donor can receive this therapy without exclusion by older age alone. We discuss the role of improved MDS prognostic scoring systems and molecular testing for selection for HSCT, and review the pre-HSCT tolerability assessment required for this advanced aged population...

Morganella morganii is a member of Enterobacteriaceae family, whose natural habitat is the human gastrointestinal tract. It rarely causes infection alone and is generally encountered in immunosuppressed patients. Osteoarticular pathologies are not commonly observed with Morganella morganii and infections by it have high mortality rate. Biofilm colonization is a causative factor behind the chronicity and/or refractoriness of certain infections. Biofilms colonize on inert medical devices, prosthesis, fibrosed tissues, sinus tracts as well as dead bones as in case of chronic osteomyelitis...
