Present status and future directions: vertical root fractures in root filled teeth.

Vertical root fracture (VRF) is a common reason for the extraction of root filled teeth. The accurate diagnosis of VRF may be challenging due to the absence of clinical signs, whilst conventional radiographic assessment is often inconclusive. However, an understanding of the aetiology of VRFs, and more importantly, the key predisposing factors, is crucial in identifying teeth that may be susceptible.

Spatiotemporal variations in the composition of algal mats in wastewater treatment ponds of tannery industry.

Wastewater Treatment Pond (WTP) is an effective remediation technology for economically developing nations. Although it's excessive organic and nutrient loads with higher water logging time triggers mixed and unprofitable microalgal mats. This may serve as a seeding source for Cyanobacterial bloom in receiving waterbodies.

In-situ green synthesis of fluorescent silica-silver conjugate nanodendrites using nanoporous frustules of diatoms: an unprecedented approach.

Generally, nanodendrite synthesis is chemical mediated and expensive. The biogenesis of such hierarchical structures is still in its nascent stage. The present study aimed at exploiting the nanoporous frustules of Halamphora subturgida, as a source of biosilica for the biosynthesis and stabilization of conjugate nanodendrites of silica and silver.

Antimicrobial Effectiveness of Calcium Silicate Sealers against a Nutrient-Stressed Multispecies Biofilm.

Purpose: This study compared the antimicrobial efficacy of calcium silicate sealers (BioRoot RCS and Total Fill BC) and conventional sealers (AH Plus and Tubli-seal) against planktonic bacteria and a nutrient-stressed multispecies biofilm.

Methods: Antimicrobial properties of freshly mixed sealers were investigated using the direct contact test (DCT) and a nutrient-stressed multispecies biofilm comprised of five endodontic strains. Antimicrobial activity was determined using quantitative viable counts and confocal laser scanning microscopy (CLSM) analysis with live/dead staining.

A critical review on use of Agrobacterium rhizogenes and their associated binary vectors for plant transformation.

Agrobacterium rhizogenes, along with A. tumefaciens, has been used to affect genetic transformation in plants for many years. Detailed studies conducted in the past have uncovered the basic mechanism of foreign gene transfer and the implication of Ri/Ti plasmids in this process.

Enhancement of ABA Sensitivity Through Conditional Expression of the Gene in Reveals Fertile Plants with Tolerance Against .

Concomitant increase of auxin-responsive factors , along with enhanced expression of in resistant compared with that in susceptible upon challenge with , revealed that abscisic acid (ABA)-auxin crosstalk is a critical factor for resistance response. Here, we induced the ABA response through conditional expression of in using the -inducible promoter. Induced ABA sensitivity caused by conditional expression of ARF10 in transgenic resulted in tolerance against and led to enhanced expression of several ABA-responsive genes without affecting the auxin biosynthetic gene expression.

Complex cardiac congenital anomalies can occasionally be found in adult patients who have no knowledge of their condition. Here we present the case of a 27-year-old man with cocaine-induced acute myocardial infarction in whom an isolated congenitally corrected transposition of the great arteries with dextroversion was discovered incidentally.

Genetic and biochemical consequences of adenosine deaminase deficiency in humans.

Adenosine deaminase deficiency accounts for approximately 15-20% of severe combined immunodeficiency in humans. The gene for adenosine deaminase is located on chromosome 20q12-q13.11 and codes for an aminohydrolase that catalyzes the deamination of adenosine and deoxyadenosine to inosine and deoxyinosine, respectively.

Use of Angio-Seal closure device when the arteriotomy is above or below the common femoral artery.

Background: The majority of vascular complications during diagnostic coronary angiography occur while accessing the femoral artery. Angio-Seal vascular closure devices are indicated for closure of arteriotomies of the femoral artery, but not when the puncture site is above or below the femoral artery.

Hypothesis: Under certain circumstances, use of the Angio-Seal closure device above or below the common femoral artery may be safe and effective.

Optimal treatment is controversial and the natural history is unknown.

Identifying cardiovascular syphilis at operation.

To describe the morphologic features so the process can be easily identified during surgery, we studied 34 patients with cardiovascular syphilis, 32 of whom underwent excision and replacement of the ascending aorta or aortic valve or both. Of the 34 patients, 22 were treated at Baylor University Medical Center from 1998 to 2008 and 12 at non-Baylor University Medical Center hospitals from 1958 to 1987. In all 34 patients, the tubular portion of the aorta was diffusely thickened and the sinus portion of the aorta was apparently uninvolved.

Luminescent Solar Concentrators--a review of recent results.

Luminescent solar concentrators (LSCs) generally consist of transparent polymer sheets doped with luminescent species. Incident sunlight is absorbed by the luminescent species and emitted with high quantum efficiency, such that emitted light is trapped in the sheet and travels to the edges where it can be collected by solar cells. LSCs offer potentially lower cost per Wp.
