background: the municipal solid wastes (msws) are disposed in open dumps, which have no leachate collection and removal system, in the caspian region of iran. leachate readily reaches the nearby water resources such as streams, rivers, lakes, and sea. therefore, understanding the quality and quantity of open dump leachate is vital to the proper treatment of leachate. methods: the leachate sampl...

introduction: video-assisted thoracic surgery (vats) is now commonly used for primary spontaneous pneumothorax. in the present study we compared the outcomes of this technique with those obtained by conventional thoracotomy.material and methods: in this cross-sectional stud, forty patients were enrolled into two groups: vats (n=20) and thoracotomy (n=20). in both groups the blebs were resected ...

the primary aim of this study is to determine maximum bite force in molar and incisor regions of healthy individuals, to evaluate the bite force after open reduction and internal fixation of mandibular fractures using micro plates, for a period of up to 6 weeks and to determine the rate of recovery of maximum bite force in an indian population.

accelerating wound healing is now considered as a principle clinical treatment and increasing the quality and speed of healing which has always been emphasized by the scientists. propolis and honey are natural bee products with wide range of biological and medicinal properties. this study was aimed to determine the synergistic effect of honey and propolis in wound healing of rat skin. a total o...

the aim of the present study was to find the effects of pre and post vitrification taxol treatment on bovineimmature cumulus oocyte complexes (cocs). bovine ovaries were collected from the local slaughterhousein a container with 30-37°c physiologic saline and supplemented with antibiotics. the grade a aspiratedcocs were assigned to 6 experimental groups; the 1st group was control (n=100) in whi...

the open pulled straw has been used effectively to vitrify preimplantation embryos because of geometricfeatures that allow rapid rates of temperature exchange. one possible inexpensive alternative to the openpulled straw are commercially-available microcapillary pipette tips commonly used for electrophoresis. themain purpose of this study was to compare the survival rates of in vitro produced b...

hypertonic saline solution can absorb part of the intracellular fluid volume into the extracellular space. the effects of this solution on the cardiovascular system are increased coronary flow and increased left ventricular contraction, without sympathetic system activation. this study was designed to assess the effects of hypertonic saline solution in open heart surgery and to compare it with ...

the management of soft tissue defects in tibial fractures is essential for limb preservation. current techniques are not without complications and may lead to poor functional outcomes. a salvage method is described using three illustrative cases whereby a combination of flaps and antibiotic-impregnated polymethylmethacrylate beads are employed to fill the bony defect, fight the infection, and p...
