Fractions obtained from partitioning of aerial methanolic extract of Euphorbia Aellenii with chloroform (E2), ethyl acetate (E3), n-butanol (E4) and water (E5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. Sample E2 appeared to have significant phytotoxic activity. In the insecticidal screening study o...

In this study, a screening of the efficacy microbial consortium bacteria and fungi isolated from activated sludge, river sediment, compost for degradation LDPE/TPS was performed. According to morphological biochemical characterization, eight bacteria, Bacillus sonorensis, subtilis, Lysinibacillus massiliensis, licheniformis, indicus, megaterium, cereus, Pseudomonas alcaligenes, five molds, Aspe...

Treatment with a converting enzyme inhibitor has been shown to stimulate aortic prostaglandin I2 synthesis. We studied whether converting enzyme inhibitor-stimulated prostaglandin I2 synthesis might be mediated by kinins. Anesthetized male Sprague-Dawley rats were given a continuous 70-minute infusion of either saline or a kinin analogue antagonist, [DArg0-Hyp3-Thi5-DPhe7-Thi8]bradykinin, 8 mic...

OBJECTIVE In men, testosterone (T) levels decline with age, and lower T predicts all-cause and cardiovascular mortality. However, the associations of T and its metabolites, dihydrotestosterone (DHT) and estradiol (E2), with symptomatic peripheral arterial disease remain unclear. We assessed associations of T, DHT and E2 with lower limb intermittent claudication in older men. DESIGN Cross-sect...

CONTEXT Testosterone (T) levels decline with age and lower T has been associated with increased mortality in aging men. However, the associations of its metabolites, dihydrotestosterone (DHT) and estradiol (E2), with mortality are poorly defined. OBJECTIVE We assessed associations of T, DHT, and E2 with all-cause and ischemic heart disease (IHD) mortality in older men. PARTICIPANTS Particip...

RING (really interesting new gene) and U-box E3 ligases bridge E2 ubiquitin-conjugating enzymes and substrates to enable the transfer of ubiquitin to a lysine residue on the substrate or to one of the seven lysine residues of ubiquitin for polyubiquitin chain elongation. Different polyubiquitin chains have different functions. Lys(48)-linked chains target proteins for proteasomal degradation, a...

We compared the antitumor efficacy and estrogen receptor (ER) degradation of CH4893237, a new orally active selective ER downregulator, with fulvestrant and tamoxifen in human breast cancer xenografts with low levels of serum estrogen (E2) (50.6, 22.9 and <16.7 pg/ml), equivalent to the ranges in postmenopausal or aromatase inhibitor-treated breast cancer patients. In addition, using proteolysi...

The purpose of this paper was to impair normal parturition in rats in order to measure tissue levels of progestins and estrogens and compare these results with those of normal parturition in rats. Abnormal parturition was obtained by injection of isotonic saline into the uterine lumen of pregnant rats at the end of pregnancy or by handling the uterus. After each of these treatments on day 21 of...

OBJECTIVE Reported associations between endogenous steroid hormone levels and cardiovascular disease in the older population have been contradictory. We evaluated plasma steroid concentrations in terms of the dimensions of the common carotid artery wall layers as a measure of the extent of atherosclerosis. METHODS A subgroup of 70-year-old participants (32 women and 50 men) from the Prospecti...
