in this study, damar batu (db) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. db is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (mw), polydispersity index (mw/mn) and glass transition temperature (tg). neat plasticized films of db are investigated for mechanical, water vapor transmission...

conclusions this case report supports the beneficial role of erythropoietin in function, maintenance, and recovery of neurons. erythropoietin is a double-edge sword, as long-term erythropoietin therapy has some complications, like thromboembolism and stroke. recent studies suggested that erythropoietin should be given as single high dose to exert a rapid neuro-protective effect with minimal hem...

background: gts, ptsm and atsm are bis-thiosemicarbazone ligands used in the preparation of copper radiopharmaceuticals. chemical structure of these materials indicates that they should have radio-protective effects. objective: to study the radio-protective effects of gts, ptsm and atsm. methods: this study has focused on radio-protective effects of these compounds at different doses (20, 40 an...

the present study aimed to determine awareness of tehran residents of seven warning signs of cancer, and application of protective measures against cancer. 2500 residents of tehran were selected through systematic cluster random sampling. data collection tool consisted of a questionnaire, comprising 3 sections of demographic details, awareness of warning signs of cancer, and application of prot...

occupational exposure to cytotoxic drugs is a global concern. we conducted this cross-sectional study in 2012 to describe the adverse effects experienced by nurses working in one of chemotherapy facilities affiliated to shiraz university of medical sciences, shiraz, southern iran, and their proper use of personal protective equipment and educational programs. the frequency of side effects repor...

Social support has been shown to be a consistent protective factor for populations with high distress. However, evidence on the role of the structure and functions of social support in reducing distress is lacking. This analysis, based on National Population Health Survey data spanning a decade, examines structures and functions of social support as drivers of reductions in psychological distress.

Mutualisms are ubiquitous in nature and equally commonplace is their exploitation. A well-known mutualism has been found to be exploited from a surprising source: the first described vegetarian spider dines on trophic structures produced by acacia trees to reward their mutualistic protective ants.

Innate immune recognition is a second protective mechanism implicating immune cells and secreted mediators. Its under the control of cells carrying receptors for recognition of foreign antigens (PRRs: pathogen recognition receptors) such as macrophages, dendritic cells, neutrophils, mastocytes, epithelial cells, NK cells, and fibroblasts which can link mi‐ crobial structures (PAMPS: pathogen as...

T-cell infiltrates are robust prognostic biomarkers in the majority of human cancers. However, the mechanisms that shape a protective T-cell response remain unclear. Our recent study implicates tertiary lymphoid structures in the shaping of an efficient and beneficial immune response in lung cancer patients.

More than 20% of U.S. paramedics are exposed to blood each year. Little is known about the circumstances that lead to these exposures. The objective of this study was to describe blood exposure events among U.S. paramedics. A mail survey was conducted in 2002-2003 among a nationally representative sample of licensed paramedics. Eighty percent of needle/lancet sticks involved non-safety devices....
