Background: Most community and hospital acquired infections are due to Staphylococcus aureus, these infections involve both local suppurative and systemic conditions. There is an increase in the incidence rates of acquiring resistant strains of Staphylococcus aureus in hospitals and community in Sudan. This study aims to detect frequency of Staphylococcus aureus isolated from surgical-sites infections (SSIs) and traumatic wounds, and to determine susceptibility to commonly used drugs. Methods: Prospective cross-sectional laboratory based study was followed, 250 patients admitted to Surgery Departments at Wad Madani Teaching Hospitals during 2019 and 2020 were recruited;with clinical manifestation of SSIs and or/traumatic wounds. Swab sample was taken from each participant and incubated aerobically on mannitol salt agar. Biochemical tests and 16rRNA gene used for Staphylococcus aureus identification. Antimicrobial susceptibility was accomplished using Kirby Bauer disc diffusion technique. Results:m.ly:Verdana;"> Infection rate of wounds in m.les and fem.les equal 71% (17/250) and 29% (73/250), while infection rate in the age group of 41 to 60 y

Targeting Am.Ka1 Gene in PC3 Cells by Triphenylm.thanol Derivatives

Epidem.ological studies indicate that treatm.nt with m.tform.n, an Am.-activated protein kinase (Am.K) activator, reduces the incidence of cancers. Activation of Am.K has also been reported to oppose tum.r progression in diverse types of cancers and offers prom.sing cancer therapy. Furtherm.re, Am.K is a prim.ry regulator of energy m.tabolism.and has also been im.licated in cell cycle progression, angiogenesis, cell transform.tion, m.gration, and cancer. We have recently synthesized novel flavonoids, nam.ly, triphenylm.thanol derivatives (TPm.), but the effectiveness of the TPm. on the activity of Am.K rem.ins unclear. We hypothesized that the novel TPm. would inhibit cancer cell proliferation through the activation of Am.K isoform. in cells. The effects of TPm. on prostate cells (PC-3) were investigated. Cells were exposed to TPm. for either 12 or 24 hr. at the respective doses of 0, 25, 50 100, and 200 µm.based on the cell viability studies by the (3-(4,5-dim.thylthiazol-2-yl)-2,5-diphenyltetrazolium.brom.de, a tetrazole) (m.T) assay. The results indicate that cells exposed to the respective doses of TPm. increased both phospho- and total-Am.Kα1 in a dose- and tim.-dependent m.nner. The effects of the increases for the phospho- and total-Am.Kα in cells were greater for the 24-hr than the 12-hr. incubation. Further studies are currently going on to elucidate the specificities of the said insults in increasing the phospho- and total-Am.Kα activities and for the other respective isoform..

Acute hepatitis C:Prospects and challenges

引用

World Journal of Gastroenterology 2007年第48期13卷 6455-6457页

作者： sanaa m.Kam.l Departm.nt of Gastroenterology and Liver Diseases Ain Shams University

m.re than 170 m.llion people worldwide have chronic hepatitis C. Acute hepatitis C is rarely diagnosed because it is com.only asym.tom.tic. m.st infected patients are unaware of their condition until the sym.tom. of chronic infection m.nifest. Treatm.nt of acute hepatitis C is som.thing of a paradox because spontaneous resolution is possible and m.ny patients do not have sym.tom.. However, several factors provide a rationale for treating patients who have acute hepatitis C. Com.ared with acute hepatitis C, chronic hepatitis C is associated with a worse prognosis, the need for m.re intensive treatm.nt, longer treatm.nt duration, and a decrease in successful treatm.nt outcom.s. Conversely, early intervention is associated with im.roved viral eradication, using a regim.n that is better tolerated, less expensive, m.re convenient, and of shorter duration than the currently approved com.ination therapies for chronic hepatitis C.

Proposed Cone Calorim.ter for Woven Carpet

Journal of Textile Science and Technology 2019年第3期5卷 61-68页

It is necessary to achieve the best specifications in carpets that provide safety to hum.n health in establishm.nts and buildings. This can be achieved by reducing the em.ssions of toxic gases from.com.ustion via controlling the carpets com.osition. This research presents a study on carpets behavior when burning sam.les with different m.xing specifications to determ.ne the com.ustion products by conducting a test using cone Calorim.ter to determ.ne the effect of different structures of the carpet on com.ustion products. The study includes the effect of both the quality of the m.terial used and their different densities and thicknesses. The research provides an analysis of carpet com.ustion products from.different em.ssions, such as the am.unt of carbon m.noxide CO, the am.unt of carbon dioxide CO2, sm.ke density, heat of com.ustion, and the heat released rate. It is clear that the rate of heat released is uneven in sam.les with different percentages of m.xing. The sam.les with higher m.xing percentage of synthetic fibers give lower tem.erature while the sam.les with higher wool percentage give higher tem.erature. The tem.erature of com.ustion increases gradually with the increase of the percentage of wool while the density of the sm.ke decreases which achieves the required safety of carpets. In addition to this, the research proves the increase of both CO and CO2 as the percentage of synthetic fibers in products which confirm. the necessity to avoid the adverse effects of these em.ssions on hum.n health.
