Genomics, epigenomics, transcriptomics, proteomics and metabolomics efforts rapidly generate a plethora of data on the activity and levels of biomolecules within mammalian cells. At the same time, curation projects that organize knowledge from the biomedical literature into online databases are expanding. Hence, there is a wealth of information about genes, proteins and their associations, with an urgent need for data integration to achieve better knowledge extraction and data reuse. For this purpose, we developed the Harmonizome: a collection of processed datasets gathered to serve and mine knowledge about genes and proteins from over 70 major online resources...

BACKGROUND: Pharmacists and health care professionals are faced with increasing and changing health care needs around the world. To meet these demands, they are required to continuously upgrade and develop their professions. Reprofessionalization is therefore crucial to the successful delivery of health services, but traditional theories might provide little practical guidance to evaluating the overall status of a profession. OBJECTIVE: This study proposes a new conceptual framework of three interrelated professional sectors: education, regulation and practice, and uses it to identify and analyze challenges facing the pharmacy profession in Jordan...

Burst release was observed when ethylene vinyl acetate copolymer (EVA) intravaginal rings were tested for progesterone release in our previous work (Helbling et al. Pharm Res. 31(3):795-808, 2014). Burst release is undesirable in controlled delivery devices because release is uncontrollable and higher levels of active pharmaceutical ingredient could lead to the occurrence of adverse effect. The present contribution is about the use of membranes to coat EVA rings to eliminate burst release. Physicochemical state of progesterone in uncoated rings and the solubility and diffusion coefficient in membrane were studied...

BACKGROUND: In recent years, the role of pharmacists has changed, as have various provincial legislations, which now allow pharmacists to provide additional health services to patients. With these changes comes growing concern about how well the current pharmacy working environment is adapting and whether it may also be creating work-related stress that may contribute to potentially unsafe practices of patient care. METHODS: To characterize the current working conditions of pharmacists in British Columbia, an online survey was developed and distributed to all College of Pharmacists of BC (CPBC) registrants by email...

Diabetic neuropathy is a complex disorder induced by long standing diabetes. Many signaling pathways and transcription factors have been proposed to be involved in the development and progression of related processes. Years of research points to critical role of oxidative stress, neuroinflammation and apoptosis in the pathogenesis of neuropathy in diabetes. Heme oxygenase-1 (HO-1) is heat-shock protein induced under conditions of different kinds of stress and has been implicated in cellular defense against oxidative stress...

Diarrhea caused by Shigella, Salmonella, and Yersinia is an important public health problem, but development of safe and effective vaccines against such diseases is challenging. A new antigen delivery platform called bacterium-like particles (BLPs) was explored as a means for delivering protective antigens from the type III secretion systems (T3SS) of these pathogens. BLPs are peptidoglycan skeletons derived from Lactococcus lactis that are safe for newborns and can carry multiple antigens. Hydrophobic T3SS translocator proteins were fused to a peptidoglycan anchor (PA) for BLP attachment...

This study was designed to assess the effects of cooling rate, storage temperature, and formulation composition on trehalose phase distribution and protein stability in frozen solutions. The data demonstrate that faster cooling rates (>100°C/min) result in trehalose crystallization and protein aggregation as determined by Fourier Transform Near-Infrared (FT-NIR) spectroscopy and size-exclusion chromatography, respectively. Conversely, at slower cooling rates (≤1°C/min), trehalose remains predominantly amorphous and there is no effect on protein stability...

The pentaethyl ester prodrug of the chelating agent diethylene triamine pentaacetic acid (DTPA) referred to as C2E5 is being developed as an orally bioavailable radionuclide decorporation agent. The predicted human efficacy obtained in these experimental animals is confounded by interspecies variations of metabolism. Therefore, in the present study, carboxylesterase-mediated metabolism of [(14)C]-C2E5 was compared in the S9 intestinal and hepatic fractions of human, dog, and rat and their respective plasma...

Jenike's approach to hopper design for a large-scale (3150 L) conical hopper was applied to pharmaceutical powders to evaluate flow issues, such as funnel flow or cohesive arching. Seven grades of microcrystalline cellulose (MCC) and six powder blends were tested. A Schulze Ring Shear Tester measured the flow function, wall friction (using stainless steel coupons with a #2B or #8 finish) and compressibility. Hopper Index (HI, maximum hopper angle required for mass flow) and Arching Index (AI, minimum hopper outlet size to prevent cohesive arch formation) were computed using Mathcad(©) ...

Gene therapy has been considered as an alternative treatment for glioblastoma therapy. In this study, a glioblastoma-specific suicide gene, pEpo-NI2-SV-TK, was delivered into the intracranial glioblastoma model using reducible poly(oligo-d-arginines) (rPOA). pEpo-NI2-SV-TK has the erythropoietin (Epo) enhancer and the nestin intron 2 (NI2) for glioblastoma specific gene expression. The in vitro studies showed that the rPOA formed stable complexes with pEpo-NI2-SV-TK. In the MTT and TUNEL assays, rPOA showed lower cytotoxicity than polyethylenimine (25 kDa, PEI25k)...

Disintegration performance was measured by analysing both water ingress and tablet swelling of pure microcrystalline cellulose (MCC) and in mixture with croscarmellose sodium using terahertz pulsed imaging (TPI). Tablets made from pure MCC with porosities of 10% and 15% showed similar swelling and transport kinetics: within the first 15 s, tablets had swollen by up to 33% of their original thickness and water had fully penetrated the tablet following Darcy flow kinetics. In contrast, MCC tablets with a porosity of 5% exhibited much slower transport kinetics, with swelling to only 17% of their original thickness and full water penetration reached after 100 s, dominated by case II transport kinetics...

MOTIVATION: Identification of differentially expressed genes is an important step in extracting knowledge from gene expression profiling studies. The raw expression data from microarray and other high-throughput technologies is deposited into the Gene Expression Omnibus (GEO) and served as Simple Omnibus Format in Text (SOFT) files. However, to extract and analyze differentially expressed genes from GEO requires significant computational skills. RESULTS: Here we introduce GEO2Enrichr, a browser extension for extracting differentially expressed gene sets from GEO and analyzing those sets with Enrichr, an independent gene set enrichment analysis tool containing over 70 000 annotated gene sets organized into 75 gene-set libraries...

Receptor-based pharmacophore modeling is an efficient computer-aided drug design technique that uses the structure of the target protein to identify novel leads. However, most methods consider protein flexibility and desolvation effects in a very approximate way, which may limit their use in practice. The Site-Identification by Ligand Competitive Saturation (SILCS) assisted pharmacophore modeling protocol (SILCS-Pharm) was introduced recently to address these issues, as SILCS naturally takes both protein flexibility and desolvation effects into account by using full molecular dynamics simulations to determine 3D maps of the functional group-affinity patterns on a target receptor...
