objective: osteoporosis or silent disease is a major bone disorder in elderly women in current century. estrogen has an important role in osteogenesis and prevention of bone fractures. hormone replacement therapy (hrt) is usually accompanied by such effects as breast and ovary cancers. thus, there is an increasing demand for replacement with plant phytoestrogens. this study is focused on determ...

in this study cellular phosphatase activity, referred to as enzyme developed color (edc) assay, was used for an in vitro assessment of cell proliferation and cytotoxicity. optimum conditions were established and found to be 10 x103 cells / well at 37°c and 60 min incubation (for developing color). under the same conditions a direct correlation between optical density (00) and cell number was ob...

objective: different techniques have been suggested for the repair of bone defects at the injured sites. use of biomembranes, or application of plasma rich in growth factor (prgf) at the site of proliferation of osteoblasts are among the suggested techniques. the current study aimed to compare the biocompatibility of human periodontal ligament fibroblasts (hplf) cultured on hypro-sorb f, perica...

biosolids must be stabilized in order to reduce odors, which have been noted as a major concernwith respect to alkaline stabilization. stabilization is designed to address potential putrefaction processes,odiferous releases and vector attraction concerns. also, most alkaline processes are open systems in whichtemperature and mixing are more difficult to control, and factors such as increased pr...

background: bone marrow mesenchymal stem cells (mscs) are one of the undifferentiated multipotential cell sources of human body. methods: mscs have the capacity to form a variety of cell types, especially chondrocytes and osteocytes. learning about responses of mscs to external milieu and chemical factors such as ph could recommend new approaches for preparation of suitable scaffolds for bone a...

It Is a commonplace observation that some people are greatly affected by even small doses of alcohol while others seem relatively tolerant to even large doses. How much of this variation in susceptibility to intoxication is genetically deter-mined? Are there environmental factors that influence susceptibility to alcohol? In an attempt to answer-these <iueStio~, we aremeaS"uOi'ig f8-3S-year-old ...

BACKGROUND Chilo partellus is an important insect pest infesting sorghum and maize. The larvae internalize in the stem, rendering difficulties in pest management. We investigated the effects of Capsicum annuum proteinase inhibitors (CanPIs) on C. partellus larvae by in-vitro and in-vivo experiments. METHODS Recombinant CanPI-7 (with four-Inhibitory Repeat Domains, IRDs), -22 (two-IRDs) and in...

Zinc oxide nanoparticles (ZnO NP) may be present in food packaging, which would put consumers at risk of NP ingestion. There is little information on the amount of ZnO NP that are present in food packaging and the effects of ZnO exposure on intestinal function. To estimate physiologically relevant ZnO exposures, foods that are naturally low in zinc (Zn), but are commonly packaged with ZnO NP, s...

We have examined the effects of various mannans, glycoproteins, oligosaccharides, monosaccharides, and sugar phosphates on the binding and phagocytosis of yeast cell walls (zymosan) by mouse peritoneal macrophages. A phosphonomannan (PO(4):mannose ratio = 1:8:6) from kloeckera brevis was the most potent inhibitor tested; it inhibited binding and phagocytosis by 50 percent at concentrations of a...

Background: Diaphragmatic hernia is an emerging threat in dairy animals due to accidental ingestion of potential foreign body via feed or fodder leads traumatic reticulo pericarditis and net results into loss milk production. Loss production diaphragmatic worrying situation among the milkman it needs be addressed early stage. Considering livelihood poor marginal farmers on animals, present stud...
