The aim of this study was to obtain a randomized, clinical and radiological comparison of implants with and without platform switching (PFS). The two compared titanium implant types differed only in the microgap position: test (PFS) or control (StE, no PFS). All implants were inserted in posterior regions and followed up for six months after abutment connection (AC). Twenty one patients with 21...

purpose: to compare the effects of short-tem and long-term systemic corticosteroids in the treatment of confirmed ocular toxoplasmosis. methods: this randomized comparative clinical trial was performed on 69 patients with confirmed active ocular toxoplasmosis with typical clinical manifestations. the subjects were randomly assigned to receive either 10 days (group a, 33 cases) or 4-6 weeks (gro...

Source term estimation (STE) of hazardous material (HAZMAT) releases is critical for emergency response. Such problem is usually solved with the aid of atmospheric dispersion modelling and inversion algorithms accompanied with a variety of uncertainty, including uncertainty in atmospheric dispersion models, uncertainty in meteorological data, uncertainty in measurement process and uncertainty i...

Elevated reticuloendothelial function and plasma fibronectin (PF) level correlate with reduced rat heat shock mortality. Procedures that enhance human PF level may offer some advantage in dealing with the adverse effects of environmental stress. Both short- (STE) and long- (LTE) term exercise programs were evaluated for their ability to increase male human PF. STE (1 week; N = 14) consisted of ...

Right ventricular (RV) and left ventricular (LV) dysfunction is an important determinant of poor clinical status in repaired patients with tetralogy of Fallot (TOF). The purpose of our study is to assess the impact of surgical repair on short-term RV and LV function by 2-dimensional speckle tracking echocardiography (STE).Sixty-seven patients (median age 12 months) with TOF before and 6 months ...

Activity-induced short-term synaptic enhancement (STE) is a common property of neurons, one that can endow neural circuits with the capacity for rapid and flexible information processing. Evidence from a variety of systems indicates that the expression of STE depends largely on the action of residual Ca2+, which enters the presynaptic terminal during activity. We have shown previously that a Ca...

Successful rehabilitation of stroke patients is strongly dependent on the engagement of patients. During a whole rehabilitation program, mundane rehabilitation exercises can easily become routine for patients, leading to boredom and as a result to ineffective functional recovery. This has been taken into consideration just by few rehabilitation systems. Engagement in rehabilitation can be decom...

The scintillation yield, scintillation decay, and x-ray excited emission of pure LaCl(3) was studied as a function of temperature between 80 and 600 K. Two broad band emissions centered around 325 nm and 400 nm were identified and correlated to emissions from two localized exciton states named STE(1) and STE(2), respectively. Different temperature dependences were observed for the short and lon...

AIMS Although the utility of two-dimensional (2D) speckle tracking echocardiography (STE) to quantify left ventricular (LV) volume has been demonstrated, this methodology is limited by foreshortened views, geometric modelling, and the assumption that speckles can be tracked from frame to frame, despite their out of plane motion. To circumvent these limitations, a three-dimensional (3D) speckle ...

Short time exposure (STE) test using rabbit corneal cell line (SIRC) cells was developed as an alternative eye irritation test. STE test uses relative viability as the endpoint after cells are exposed to the test material at constant concentrations for 5 min. In this inter-laboratory study with 3 laboratories, 44 chemicals with a wide range of classes were evaluated for the transferability, bet...
