BACKGROUND AND PURPOSE Sinus lift (SL) using cultured autogenous periosteal cells (CAPCs) combined with autogenous bone and platelet-rich plasma (PRP) was performed to evaluate the effect of cell administration on bone regeneration, by using high-resolution three-dimensional computed tomography (CT). MATERIALS AND METHODS SL with autogenous bone and PRP plus CAPC [CAPC(+)SL] was performed in ...

OBJECTIVE To evaluate the effectiveness of slitlamp optical coherence tomography (SL-OCT) and Scanning Peripheral Anterior Chamber depth analyzer (SPAC) in detecting angle closure, using gonioscopy as the reference standard. METHODS A total of 153 subjects underwent gonioscopy, SL-OCT, and SPAC. The anterior chamber angle (ACA) was classified as closed on gonioscopy if the posterior trabecula...

BACKGROUND The readiness of academics to engage in the service-learning (SL) institutionalisation process is not accentuated in research on SL institutionalisation in South Africa. The argument has been advanced that SL scholarship and willingness of key stakeholders are crucial for SL institutionalisation at the academic programme level. AIM The research focus of the study being reported her...

We have studied the interaction of the aminoglycoside drug, paromomycin, with a 171-mer from the packaging region of HIV-1 (psi-RNA), using quantitative footprinting and circular dichroism spectroscopy. The footprinting autoradiographic data were obtained by cutting end-labeled RNA with RNase I or RNase T1 in the presence of varying paromomycin concentrations. Scanning the autoradiograms produc...

introduction: the aim of the present experimental study was to evaluate the push-out bond strength of dorifill, epiphany and mta-fillapex sealers to root canal dentin in presence and absence of smear layer (sl). methods and materials: sixty human single-rooted teeth were selected and divided into six groups ( n= 10). the canal irrigation protocol in groups 1, 3 and 5 consisted of 2.5% naocl dur...

Background: Monte Carlo method (MC) has played an important role in design and optimization of medical linacs head and beam modeling. The purpose of this study was to compare photon beam features of two commercial linacs, Varian 21EX and Elekta SL-25 using MCNP4C MC code. Materials and Methods: The 6MV photon beams of Varian 21EX and Elekta Sl-25 linacs were simulated based on manufacturers pro...

BACKGROUND Treatment-resistant chronic rhinosinusitis (CRS) imposes a clinical challenge. Its pathogenesis may be associated with dysregulated immune/inflammatory responses in the sinus. OBJECTIVE To evaluate production of types 1 and 2 T cytokines (interferon gamma [IFN-gamma] and interleukin [IL] 5/IL-4, respectively) and regulatory/inflammatory cytokines (IL-10, IL-12, and IL-18) by sinus ...

The activity of oxidative and hydrolytic enzymes of the edible and medicinal white rot fungi Coprinus cinereus (Schaeff.) Gray mushroom was observed during mycelia growth and fruiting body development in solid substrate fermentation using sisal waste fractions amended with cow dung manure as supplement. Laccase had the highest titre value among the five detected enzymes. Its activity was higher...

The present study aspired to scrutinize the relationship among EFL learners' Self-directed Learning (SL), Resilience (RE), and Willingness to Communicate (WTC). To accomplish this purpose, 124 male and female undergraduate EFL learners, within the age range of 20 to 32, were selected through convenience sampling. These EFL learners were asked to fill in three questionnaires, namely the SL...
