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-...

The deleterious effects of three cryoprotectants, glycerol, dimethylsulfoxide (DMSO), and dimethylacetamide (DMA), were compared on fowl spermatozoa. The viability and integrity of spermatozoa were measured with eosin-nigrosin smears. Glycerol was the least deleterious cryoprotectant, followed by DMA, and DMSO was the most toxic. Methods employing either glycerol or DMA were then compared for t...

BACKGROUND Arsenic is an ubiquitous element linked to carcinogenicity, neurotoxicity, as well as adverse respiratory, gastrointestinal, hepatic, and dermal health effects. OBJECTIVE Identify dietary sources of speciated arsenic: monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA). METHODS Age-stratified, sample-weighted regression of NHANES (National Health and Nutrition Examinatio...

We have designed and synthesized DNA duplexes containing 5-dimethylaminocytosine ((DMA)C) to investigate the effects of C(5)-substituted cytosine bases on the transfer and trapping of positive charge (holes) in DNA duplexes. Fluorescence quenching experiments revealed that a (DMA)C base is more readily one-electron oxidized into a radical cation intermediate as compared with other natural nucle...

A DMA controller that operates in the cycle-stealing mode is allowed to transfer data only when the CPU does not need the system bus. Thus, the execution time of a cycle-stealing DMA I/O task depends on the sequence of instructions executing concurrently with it. This paper describes a method for bounding the worst-case execution time (WCET) of a cycle-stealing DMA I/O task. We rst deene the ta...

Methylated forms of arsenic (As), monomethylarsenate (MMA) and dimethylarsenate (DMA), have historically been used as herbicides and pesticides. Because of their large application to agriculture fields and the toxicity of MMA and DMA, the distribution, speciation, and sorption of methylated As to soils requires investigation. Monomethylarsenate and DMA were reacted with a soil up to one year un...
