BACKGROUND Iran started a new public-private partnership model in form of health coopera¬tives which is somehow different from other types of health cooperatives throughout the world. In this study we compared the performance and quality of health services in public health cen¬ters (PHCs) and cooperative health centers (CHCs). METHODS In this comparative study performance quality of two cohor...

Biodegradable poly(l-lactic acid) (PLLA) and PLLA/CoFe2O4 magnetic microspheres with average sizes ranging between 0.16-3.9μm and 0.8-2.2μm, respectively, were obtained by an oil-in-water emulsion method using poly(vinyl alcohol) (PVA) solution as the emulsifier agent. The separation of the microspheres in different size ranges was then performed by centrifugation and the colloidal stability as...

BACKGROUND Poly(L-lactide) (PLLA) is a biodegradable polymer currently used in many biomedical applications, including the production of resorbable surgical devices, porous scaffolds for tissue engineering, nanoparticles and microparticles for the controlled release of drugs or antigens. The surfaces of lamellar PLLA single crystals (PLLAsc) were provided with amino groups by reaction with a mu...

Polyhroxyalkanoates (PHAs) are macromolecular storage polyesters produced by metabolic transformation of carbon sources by microorganisms, under nutrient limiting conditions. The latter involves excess of carbon source and limiting concentrations of at least one other essential nutrient, such as nitrogen, phosphorous, and/or sulphur.1 PHA accumulation as intracellular carbon and energy reserves...

This study aimed to identify programmatic vulnerability to STDs/HIV/AIDS in primary health centers (PHCs). This is a descrip - tive and quantitative study carried out in the city of São Paulo. An online survey was applied (FormSUS platform), involving administrators from 442 PHCs in the city, with responses received from 328 of them (74.2%), of which 53.6% were nurses. At - tention was raised i...

The study was intended to find how the Primary Health Centers in the Selected Tribal Districts of Karnataka-India are functioning and to reveal their problems and prospects. Cross-sectional, Observational study was done in a total of 35 PHCs, randomly selected from the three tribal dominant districts of Karnataka (Mysore, Chamaraja Nagar and Kodagu). A total of 35 medical and 50 para-medical st...

One-dimensional photonic crystals (1D PhCs) have a unique ability to control the propagation of light waves, however certain classes 1D oxides remain relatively unexplored for use as PhCs. Specifically, there has not been comparative study three different PhC structures compare influence layer thickness, number, and refractive index on PhCs transmission. Herein, we transfer matrix method (TMM) ...

Effects of bimodal distribution of microand nano-HA particles on the mechanical properties such as bending strength, modulus and J-integral at crack initiation, Jin, of HA/PLLA composites were investigated. The Bending properties were improved by bimodal distribution. It is considered that in bimodal HA/PLLA, PLLA molecular chains are constrained by existence of HA particles, resulting in the r...
