Background and Objective: Determination of hormone receptor status in the management of breast cancer is well-established. The aim of this study was to evaluate the frequency of androgen receptor (AR) expression in invasive ductal carcinoma of breast. Materials and Methods: For this purpose, 55 cases of invasive ductal breast carcinoma were examined using a monoclonal antibody against AR on...

The mammalian visual system processes many different aspects of the visual scene in separate, parallel channels. Recent experiments suggest that the visual cortex, like the retina, forms parallel circuits even at very fine spatial scales.

A thermodynamic equilibrium model was developed to predict the gasification process in a bench-scale fluidized bed gasifier. Potato shoot (leaves and stems) was used as the feedstock of the gasifier. The experiments were done in five different gasification zone temperatures (650, 700, 750, 800 and 850°C), with a feeding rate of 0.166 kg/hour, and two equivalence ratios (ER: 0.2 and 0.25). T...

Background: Breast cancer is one of the most common women’s cancers, and the number of cases is increasing worldwide. Objective: The current study compared invasive lobular carcinoma (ILC) and invasive ductal carcinoma with regard to the prevalence of estrogen receptor (ER), progesterone receptor (PR), and age prevalence. Methods: T...

Introduction: Intracellular pH (pHi) regulates essentially all aspects of cellular activities. However, it is unknown how endoplasmic reticulum (ER) potassium channels sense pHi. In this study, we investigate the direct effects of pHi on ER potassium channels. Methods: We used channel incorporation into the bilayer lipid membrane method. L-α-phosphatidylcholine, a membrane lipid, was extrac...
