Plants produce reactive oxygen species (ROS) in response to environmental stresses sending signaling cues, which, if uncontrolled, result in cell death. Like other aerobic organisms, plants have ROS-scavenging enzymes, such as superoxide dismutase (SOD), which removes superoxide anion radical (O(2)(-)) and prevents the production and buildup of toxic free radicals. However, increasing the expre...

Superoxide reductase SOR is an enzyme involved in superoxide detoxification in some microorganisms. Its active site consists of a non-heme ferrous center in an unusual [Fe(NHis)(4) (SCys)(1)] square pyramidal pentacoordination that efficiently reduces superoxide into hydrogen peroxide. In previous works, the reaction mechanism of the SOR from Desulfoarculus baarsii enzyme, studied by pulse radi...

yes, some are. acupuncture relieves subjective symptoms of asthma and reduces medication use in mild to moderate asthma (strength of recommendation [sor]: A, based on systematic review of randomized controlled trials [rCTs] of variable quality). Herbal medications, such as Ginkgo biloba, appear to improve lung function, while herbs such as Tylophora indica and Tsumura saiboku-to may decrease as...

Previous studies reported low benznidazole (BNZ) loading in conventional emulsions due to the weak interaction of the drug with the most common oils used to produce foods or pharmaceuticals. In this study, we focused on how the type of surfactant, surfactant-to-oil ratio w/w (SOR) and oil-to-water ratio w/w (OWR) change the phase behavior of different lipid-based drug delivery systems (LBDDS) p...

As more clinical information with increasing diversity become available for analysis, a large number of features can be constructed and leveraged for predictive modeling. Feature selection is a classic analytic component that faces new challenges due to the new applications: How to handle a diverse set of high dimensional features? How to select features with high predictive power, but low redu...

Successive over-relaxation (SOR) is a computationally intensive, yet extremely important iterative solver for solving linear systems. Due to recent trends of exponential growth in amount of data generated and increasing problem sizes, serial platforms have proved to be insufficient in providing the required computational power. In this paper, we present parallel implementations of red-black SOR...

IT IS UNCLEAR, but studies suggest that it should be based largely on individual risk. The American Academy of Pediatric Dentistry recommends a 6-month interval for preventive dental visits (strength of recommendation [SOR]: C, expert opinion), but a 24-month interval does not result in an increased incidence of dental caries in healthy children and young adults or increased incidence of gingiv...

Clinical evaluation and chest x-ray are recommended for asymptomatic patients with a positive purified protein derivative (PPD) test result, to exclude the slight possibility of active tuberculosis (TB). Patients with radiographic evidence of old (healed) TB infection should also undergo sputum testing (strength of recommendation [SOR]: C, expert opinion). Treatment with isoniazid (INH) monothe...

There are 3: valacyclovir, acyclovir, and topical penciclovir. valacyclovir, 2 g twice in 1 day taken during the prodromal stage of herpes labialis, reduces the episode duration and time to healing. Acyclovir, 400 mg, taken 5 times a day for 5 days, decreases the pain duration and healing time to loss of crust (strength of recommendation [sor]: a, based on randomized controlled trials [rCTs]). ...
