alkanes c2 c4/breast neoplasms

Polyfluorinated iodine alkanes (PFIs) are a kind of emerging chemicals with endocrine disrupting effects. Based on the different binding preferences of PFIs to estrogen receptor alpha and beta isoforms (ERα and β), two representative PFIs, dodecafluoro-1,6-diiodohexane (PFHxDI) and

BACKGROUND In 1994, a hazardous waste site, polluted by the dumping of solvents from a former electronics factory, was discovered in Taoyuan, Taiwan. This subsequently emerged as a serious case of contamination through chlorinated hydrocarbons with suspected occupational cancer. The objective of

Aiming to develop multitarget drugs for the anticancer treatment, a new class of chalcone-pyrrolo[2,1-c] [1,4]benzodiazepine (PBD) conjugates linked through a 1,2,3-triazole moiety containing alkane spacers has been designed and synthesized. Combining these two core pharmacophore structures with

This research focused on green engineering and characterization of silver (PcAgNPs) and copper nanoparticles (PcCuNPs) using Prosopis cineraria (Pc) leaf extract prepared by using microwave irradiation. We studied their enhanced antimicrobial activity on human pathogens as well as cytotoxicity on

Plants from the Bursera genus are widely distributed in the tropical dry forests of Mexico. In traditional medicine, extracts from different species of Bursera have been used for a wide range of biological activities, including the treatment of cancer-related symptoms. Compounds present in the

Breast cancer is accompanied by increased oxidative stress and induction of polymorphic cytochrome P-450 mixed oxidase enzymes (CYP). Both processes affect the abundance of volatile organic compounds (VOCs) in the breath because oxidative stress causes lipid peroxidation of polyunsaturated fatty

BACKGROUND Carcinogenic products in the exhaled breath of cancer patients are of growing medical interest as they can serve as noninvasive disease markers. Breath analysis can be used as an alternative or complementary diagnostic tool in breast cancer patients who have a different pattern of

Oxidative stress (OS) refers to the process of oxidative damage caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS) accumulated by the organisms or cells during the process of generating and scavenging oxygen free radicals. In this study, an OS model of MCF-7 cells was

Several affinity chromatography reagents have been proposed for purification of progesterone receptor (PgR), and significant results have been achieved with some of these. None, however, have approached the results achieved in affinity chromatography of estrogen receptor. We have therefore

The N-terminal sequence of the Smac/DIABLO protein is known to be involved in binding to the BIR3 domain of the anti-apoptotic proteins IAPs, antagonizing their action. Short peptides and peptide mimetics based on the first 4-residues of Smac/DIABLO have been demonstrated to re-sensitize resistant

We have investigated mammary gland tissues of female rats treated with 7,12-dimethylbenz[a]anthracene in sesame oil by a near infrared (NIR) spectroscopy finding that the DNA and water contents in the cancerous tissues were larger than those in the normal tissues but that the lipid content in the

A series of 3',4',5'-trimethoxy flavonoids with benzimidazole linked by different chain alkanes have been designed and synthesized. The potential activity of these compounds as anti-tumor agents was evaluated by cytotoxicity assay in MGC-803 (human gastric cancer), MCF-7 (human breast cancer),

β-Glucan-binding protein (βGBP) is important for the rational expansion of molecular biology. Here, zinc oxide nanoparticle (ZnONP) was synthesized using βGBP from the crab Scylla serrata (Ss-βGBP-ZnONP). Ss-βGBP-ZnONP was observed as a 100 kDa band on sodium dodecyl sulfate polyacrylamide gel and

Scrophularia atropatana (S. atropatana), an Iranian plant belonging to the family of Scrophulariaceae, was assigned for its chemical compositions and biological activities of essential oil (EO) and extracts of the aerial parts of the plant during the flowering stage. Combination
