Although selective estrogen receptor modulators (SERMs) are useful in the treatment and prevention of breast cancer, the SERM tamoxifen has been associated with an increased risk of endometrial cancer possibly due to metabolism to electrophilic quinoids. Another SERM, arzoxifene is currently in clinical trials for the treatment of breast cancer, and since it has similar structural characteristi...

A study was made of the effects of 2,3-dimethylmaleic anhydride (DMA), a reagent removing positive charges, on the aggregation and surface charge of embryonic chick neural retina cells. Neural retina cells, recovered from the dissociation procedure, were cultured on a gyratory shaker and the aggregate dimaeters formed in the presence of DMA or DMA-serum dialysate, following DMA-pretreatment, or...

Direct Memory Access DMA is frequently used to transfer data between the main memory of a host computer and the interconnection network in order to free the host processor from the burden of the trans fer DMA operations are traditionally initiated by the operating system kernel mainly to prevent one appli cation from tampering with another applications data Recent architecture trends suggest th...

Attackers constantly explore ways to camouflage illicit activities against computer platforms. Stealthy attacks are required in industrial espionage and also by criminals stealing banking credentials. Modern computers contain dedicated hardware such as network and graphics cards. Such devices implement independent execution environments but have direct memory access (DMA) to the host runtime me...

N,N-Dimethylacetamide (DMA) is a water-miscible solvent, FDA approved as excipient and therefore widely used as drug-delivery vehicle. As such, DMA should be devoid of any bioactivity. Here we report that DMA is epigenetically active since it binds bromodomains and inhibits osteoclastogenesis and inflammation. Moreover, DMA enhances bone regeneration in vivo. Therefore, our in vivo and in vitro...

BACKGROUND The impact of surgery on end of life care for patients with disseminated malignancy (DMa) is incompletely characterized. The purpose of this study was to evaluate postoperative outcomes impacting quality of care among DMa patients, specifically prolonged length of hospital stay, readmission, and disposition. METHODS The American College of Surgeons National Surgical Quality Improve...

Sperm carbohydrate binding activity is involved in gamete recognition. We identified a human sperm protein extracted under reducing conditions, and with a molecular mass of 65 kDa on sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), and which binds D-mannose coupled to albumin (DMA) in presence of cations and a neutral pH. Epifluorescence microscopy showed that fluorescein-...
