biomolecular behavior of tumor cells has become attractive to investigators. p53 as an oncosuppresor gene has been core of various studies and ki67 is a nuclear protein involved in proliferation process. stopping of onco-suppressor function theoretically allows proliferative system to get out of any control. in this case-control study we evaluated 50 patients with non small cell lung cancer, co...

introduction: primary small cell carcinoma of theesophagus (pscec) associated with paraneoplastic sweating syndrome is a rare disease characterized with rapid growth rate, metastasis at the time of diagnosis, and poor prognosis. the lung is the most common site for small cell carcinoma but this malignancy includes 0.1% to 1% of all gastrointestinal and 0.8% to 2.7% of esophageal malignancies. s...

introduction: in radiotherapy, methods of treatment planning are becoming increasingly more complicated. this requires verification of the doses delivered to increasingly smaller and more precise regions. radiotherapy techniques are continuously employing smaller and smaller field sizes to deliver tighter radiation doses with higher therapeutic ratios, generating interest among researchers to p...

staphylococcus aureus produces a particular morphological variant called small colony variant (scv) which is responsible for persistent subclinical infections in predisposed individuals and is usually resistant to aminoglycosides and cell wall active antibiotics. infections by scv of s. aureus are an upcoming problem due to difficulty in laboratory diagnosis and resistance to antimicrobial chem...

an 8-month-old female thoroughbred foal was presented showing signs of colic. the foal was anxious,exhibiting signs of abdominal pain and distention. the foal had tachycardia (120 beats/min), tachypnea (40breaths/min). blood samples obtained for haematologic and serum biochemistry analysis that showed a pcvof 30% and a tpp of 70 g/l. the peritoneal fluid analysis revealed a clear fluid with mil...

mitral valve regurgitation (mvr) is a common valvular disease in dogs. hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (vfm), which shows the blood flow within the ventricles in vector and vortex flows. blood flow within the left ventricle of mvr dogs was compared at different stages of mvr and to that of normal dogs. 14 normal dogs and...

freshwater lens on small islands may easily be overexploited or polluted due to overdrafts of fresh water by pumping which causes drawdown of the water table a rise or up-coning of the saltwater interface. present study is concerned with using a three-dimensional finite-difference numerical model to simulate the groundwater flow and transport model to predict the behavior of groundwater system ...
