The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...

Background: Matrix MetalloProteinases (MMPs) degrade extracellular matrix components to provide normal remodeling and contribute to pathological tissue destruction and cell migration in endometriosis. It is accepted that MMPs are resistant to suppression by progesterone in endometriotic tissues. The physiological effects of progesterone are mediated by its two progesterone receptor (PR) isoform...

Rhizoctonia muneratii ATCC 13247 was capable of catalyzing the conversion of 25-hydroxycholesterol to the 3-oxo-4-ene. Hydroxylation at the 6alpha and 6beta positions with the concomitant 3-oxo-4-ene transformation was also observed. The addition of Triton X-100 to the growth medium immediately before steroid addition selectively prevented the appearance of the respective 6alpha-hydroxylated pr...

A beamspace root modification of PseudoRandom Joint Estimation Strategy (PR-JES) [1] is developed. The essence of PR-JES is to generate the eigenstructure-based estimator bank for given sample covariance or data matrix. Combining the results of “parallel” underlying estimators, PR-JES removes the outliers and improves the threshold performance. In the case of non-uniform array, the interpolated...

A new iridium catalyst containing an imine-diphosphine ligand has been developed, which showed high efficiency for the hydrogenation of CO2 to formate (yield up to 99%, TON up to 450 000). A possible catalytic mechanism is proposed, in which the imine group of the catalyst plays a key role in the cleavage of H2 and the activation of CO2.

  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...

background and objectives: breast cancer is the most common malignancy among women in the world. the aim of this study was to assess estrogen receptor (er), progesterone receptor (pr) and her-2/neu of infiltrating ductal carcinoma (idc) with tumor size, histologic grade, lymph node metastasis and age. methods: this study was carried out on 300 tissue blocks ofpatients with idc who underwent mas...
