Exploring Genetics by Environment Interactions in Some Rice Genotypes across Varied Environmental Conditions.

Rice production faces challenges related to diverse climate change processes. Heat stress combined with low humidity, water scarcity, and salinity are the foremost threats in its cultivation. The present investigation aimed at identifying the most resilient rice genotypes with yield stability to cope with the current waves of climate change.

The endocrine disrupting alkylphenols and 4,4'-DDT interfere with estrogen conversion and clearance by mouse liver cytosol.

Endocrine disrupting chemicals (EDCs) are ubiquitous compounds known for negative impacts on reproductive functions and for increasing cancer risk. EDCs are believed to cause the harmful effects in part through their inappropriate low-affinity binding to steroid receptors and other possible non-receptor mediated paradigms, however there is a need to further elucidate other mechanisms involving the direct and indirect impact of EDCs on reproductive functions. We examined the metabolism of 17β-estradiol (E2) and estrone (E1) by cell-free hepatic cytosol in the presence of alkylphenols (nonylphenol/NP and 4-tert-octylphenol/tOP), Dichlorodiphenyltrichloroethane (4,4'-DDT) and other EDCs.

A study of parabens and bisphenol A in surface water and fish brain tissue from the Greater Pittsburgh Area.

Pollution from xenoestrogens has been discovered in the aquatic environment of the Greater Pittsburgh Area and is suspected to be caused by the failing sewer system. Personal care products and plasticizers have the potential to enter the water supply though treated and untreated sewage. Many of these compounds are suspected xenoestrogens.

Efficacy of signal pathway inhibitors alone and in combination with Cisplatin varies between human non-small cell lung cancer lines.

Background: Signal pathway inhibitors (SPI) are designed to act synergistically with conventional cytotoxic drugs to control cancer progression. The objective of this study was to evaluate the effect of various SPI, both alone and in combination with cisplatin, on three different non-small cell lung cancer (NSCLC) cell lines.

Materials And Methods: Cell lines (A549, 201T, 273T) representing NSCLC were treated for 72 h in the presence or absence of inhibitors to PI3K (LY-294002; Tocris Bioscience, Ellisville, MO), BCL-2 (Gossypol; Sigma-Aldrich, St.

Use of novel autoantibody and cancer-related protein arrays for the detection of esophageal adenocarcinoma in serum.

Objective: The aim of this study was to evaluate the feasibility of using novel autoantibody and cancer-related protein arrays to identify potential biomarkers for the early detection of esophageal adenocarcinoma in serum.

Methods: Sera from 18 patients with esophageal adenocarcinoma and 14 with gastroesophageal reflux disease were added to microarrays designed to detect circulating autoantibodies to 51 tumor-associated antigens. Sera from the same patients were also added to a 53-plex assay for various cancer-related proteins.
