Background & Objectives: Although Cox regression is commonly used to detect relationships between patient survival and demographic/clinical variables, there are situations where parametric models can yield more accurate results. The objective of this study was to compare two survival regression methods, namely Cox regression and parametric models, in patients with gastric carcinoma registered a...

Background & Aims: Tuberculosis is one of the most important diseases of century that involves all the human organs including lungs. Due to the yearly occurrence of 9 millions new cases and 1.5 millions deaths in the world, tuberculosis is in the center of attention. The aim of this study was to indentify factors affecting the time required for sputum smear conversion in patien...

Cyclooxygenase (COX) is the key enzyme required for the conversion of arachidonic acid to prostaglandins. Two cycloxygenase isoforms have been identified and are referred to as COX-1 and COX-2. Both enzymes are blocked by nonselective anti-inflammatory drugs (NSAID), such as indomethacin and ibuprofen. COX-1 is an enzyme normally found in tissues and is involved in physiological functions, whil...

Cyclooxigenase (COX) is the rate-limiting enzyme for the conversion of arachidonic acid (AA) to prostaglandins (PGs). Two isoforms of COX have been identified: COX-1 is constitutively expressed in many cells and is involved in cell homeostasis, angiogenesis and cell-cell signalling; COX-2 is not expressed in normal condition however it is strongly expressed in inflammation. The oral cavity is c...

Background: Clinical course of Clinically Isolated Syndrome (CIS) is variable, and identifying patients who will eventually develop Multiple Sclerosis (MS) is essential. Objectives: To assess the conversion rate of CIS to Clinically Definite Multiple Sclerosis (CDMS) and its predictors in southern Iran. Materials & Methods: A total of 143 CIS patients registered to Fars Multiple Sclerosis Soc...

Statistical analysis of non-normal data is usually more complicated than that for normaldistribution. In this paper, a simple root/power transformation technique developed by Niaki, et al [1]is extended to transform right and left skewed distributions to nearly normal. The value of theroot/power is explored such that the skewness of the transformed data becomes almost zero with anacceptable err...

Background & Objectives: Tuberculosis (TB) is the largest single cause of death from infectious diseases and has a ten rating of global burden of disease. Despite the availability of effective treatment for pulmonary TB, sputum conversion of patients affected by various factors. This study aimed to determine the time course of sputum conversion in patients and possible affected factors in this ...

Neuroblastoma is the single most common and deadly tumor of childhood and is often associated with therapy resistance. Cyclooxygenases (COXs) catalyze the conversion of arachidonic acid to prostaglandins. COX-2 is up-regulated in several adult epithelial cancers and is linked to proliferation and resistance to apoptosis. We detected COX-2 expression in neuroblastoma primary tumors and cell line...
