background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...

background :wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. we investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (hsv-1) in cell culture.   methods : in-vitro c...

Introduction: Oxidative stress has been implicated in the pathogenesis of various diseases affecting chondrogenesis or the function of articular cartilage. The purpose of the present study was to find the effect of soybean extract on reduction of detoriation effects of oxidativestress in embryonic chondrogenesis in vitro. Methods: In order to separate ectoderm from mesenchyme, the limb buds ...

The authors examined postural asymmetries during quiet stance and while holding evenly or unevenly distributed loads. Right-hand dominant subjects preferentially loaded their right lower limb when holding no load or a load evenly distributed in both hands, but no differences in center of pressure (CoP) were observed between the left and right limbs. However, longer CoP displacement was observed...

Background: Evaluation of maturation genes expression and their pattern during in vitro culture of vitrified preantral follicles is an essential and could promote either vitrification procedure or culture condition. Materials and Methods: Preantral follicles (with 100- 130 μm diameter) isolated mechanically from 12-14 days old NMRI mice ovaries and divided into vitrification and control groups....

introduction: there are some internal and external factors in the development and supporty of joint. the role of movement on foint development could be study in three methods. in vitro limb buds culture limb bud graft to coelomic membrance. neuromuscular function block. the development of the fourth metatarsophalyngeal joint of swiss mice was studied in normal circumstances and the absence of m...
