After an initial febrile viral syndrome, infection with Ebola virus often induces an explosive late "Ebola sepsis-like syndrome" which appears very similar to some phenotypes of bacterial sepsis and is commonly fatal. It is possible that direct and diffuse viral infection of both the endothelium and epithelium of the colon may cause sufficient disruption of both the endothelial and epithelial b...

The long-term success of root canal treatment requires the prevention bacterial leakage between walls and obturation. In this study, we compared Enterococcus faecalis in thirty single-rooted mandibular premolars divided into three groups. roots two experimental groups were obturated using a single-cone obturation technique with different bio-ceramic sealers (MTA Fillapex CeraSeal) while convent...

Infectious diseases remain a major health problem, where sepsis and other severe infectious diseases are common causes of morbidity and mortality. The importance of early and appropriate treatment of sepsis and severe bacterial infections has been underlined by the successes of measures like the Surviving Sepsis Campaign, among others. Thus, there is a need for clinical and laboratory tools to ...

objective: in a cavity prepared through endodontic surgery, application of a material to provide apical seal and prevent bacterial and tissue exudates is of great importance. the purpose of this study was to compare the sealing ability of biocalex with white mta, gray mta, and amalgam as root-end fillings. materials and methods: sixty-six single-rooted extracted human teeth were cleaned, shaped...

We report a case of recurrent Streptococcus Pneumoniae meningoencephalitis with a transethmoidal meningoencephalocele (TEME) but without cerebrospinal fluid (CSF) leakage.A 35-year-old man was admitted with S. pneumoniae meningitis. He had suffered from four episodes of recurrent pneumococcal meningitis during the previous 4 years. A computed tomography scan of the paranasal sinus showed the TE...

In a 2.5-year-long environmental engineering experiment in the By Fjord, surface water was pumped into the deepwater where the frequency of deepwater renewals increased by a factor of 10. During the experiment, the deepwater became long-term oxic, and nitrate became the dominating dissolved inorganic nitrogen component. The amount of phosphate in the water column decreased by a factor of 5 due ...

Streptococcal toxic shock syndrome (STSS) caused by Streptococcus pyogenes is a clinical condition with a high mortality rate despite modern intensive care. A key feature of STSS is excessive plasma leakage leading to hypovolemic hypotension, disturbed microcirculation and multiorgan failure. Previous work has identified a virulence mechanism in STSS where M1 protein of S. pyogenes forms comple...

In this paper, the N2O plasma oxides in-situ grown on CF4 plasma pretreated silicon substrate is proposed and demonstrated having excellent characteristics. Those are precise thickness control, low temperature fabrication, low leakage current, and high reliability. Those good features will enhance the scaling down ability of CMOS devices. The mechanisms that make the process success are also di...

Based on fluoride-based plasma treatment of the gate region in AlGaN/GaN HEMTs and post-gate rapid thermal annealing (RTA), enhancement mode (E-mode) AlGaN/GaN HEMTs with low on-resistance and low knee-voltage were fabricated. The fabricated E-mode AlGaN/GaN HEMT with 1 μm-long gate exhibits a threshold voltage of 0.9 V, a kneevoltage of 2.2 V, a maximum drain current density of 310 mA/mm, a pe...
