In this study, effect of solvent system on in vitro granisetron HCl release from injectable in situ forming implants were investigated also by means of gamma irradiation sterilization. Implant formulations contain 56% solvent, 38% polymer and 6% drug. For the preparation of the formulations, hydrophobic benzyl benzoate and moderately hydrophobic prophylene carbonate were used as solvents while ...
Human eye is made of a number of structural components to deliver vision, and cornea is the front window of the eye. Human cornea is made of soft biological materials. It is unfriendly for exposures to the common energy levels of X-ray scans for repeated probing of its structural architecture. Here we study an alternative imaging methodology by using a normal white-light source. By exploiting t...
A conserved transcription-translation negative feedback loop forms the molecular basis of the circadian oscillator in animals. Molecular interactions within this loop have been relatively well characterized in vitro and in cell culture; however, in vivo approaches are required to assess the functional significance of these interactions. Here, regulation of circadian gene expression was studied ...
Deregulated signal transduction via the epidermal growth factor (EGF) receptor family of tyrosine protein kinase growth factor receptors is associated with proliferative diseases such as cancer and psoriasis. In an attempt to selectively block signal transduction from the EGF receptor, we have synthesized a new class of dianilino-phthalimide tyrosine protein kinase inhibitors with selectivity f...
How do scientists think, reason and generate new models and theories? How do scientists represent their knowledge? Answers to these questions are of paramount importance not only in understanding what science is, but also in assessing different theories of science. Surprisingly, we know little about the basic processes that are involved in current-day scientific thinking. The goal of my researc...
Hypothesis / aims of study Human vaginal wall biomechanical properties have been tested ex vivo in frozen/thawed tissue samples (1), and more recently in fresh anterior vaginal wall samples (2). In vivo testing of human tissues with a cutometer-like device originated with the study of wound healing in plastic surgery. Application to the human vaginal wall is under investigation with inconclusiv...
abstract this mixed method study examines whether there is any relationship among the variables of the study (job satisfaction, social capital and motivation). the researcher considered job satisfaction and social capital as independent variables; motivation is the dependent variable of the study. the researcher applied a questionnaire to assess each variable. to measure efl teachers’ job sati...
