Photoreduction of Dye with Noble Metal Gold Permeated with Metal Oxide Titania.

Photoactive degradation of textile malachite green (MG), methylene blue (MB) dyes has been permeated on metal oxide TiO₂ nanoparticles under sunlight. Semiconductor photocatalysis is a promising method for removal of toxic chemicals from wastewater produced by industry. Due to tunable bandgap, TiO₂ among various semiconductor studied mostly.

Role of Vitamin C and E supplementation in reduction of serum level of renal injury marker following shock wave lithotripsy: Prospective single centre experience.

Introduction: Shock wave lithotripsy has become first line treatment modality for renal calculi due to its noninvasiveness. However, the destructive forces like dispersion of cavitation bubbles can cause trauma to thin-walled vessels and renal parenchyma during fragmentation of the stones. Antioxidants are our first line of defense against oxidative stress.

Laparoscopic repair of urogenital fistulae: A single centre experience.

Context: Sparse literature exists on laparoscopic repair of urogenital fistulae (UGF).

Aims: The purpose of the following study is to report our experience of laparoscopic UGF repair with emphasis on important steps for a successful laparoscopic repair.

Settings And Design: Data of patients who underwent laparoscopic repair of UGF from 2003 to 2012 was retrospectively reviewed.

DNA sequence detection based on Raman spectroscopy using single walled carbon nanotube.

A Biosensor for detection of DNA sequence in bacterium Bacillus anthracis has been developed using Raman spectrum of single walled carbon nanotubes (SWNTs). We have utilized the fact that being hydrophobic in nature single strand of target DNA (diseased DNA) gets wrapped over SWNT surface forming single stranded DNA-SWNT complex. The sensing ability of this sensor has been studied using the dependency of G peak intensity (in the Raman spectrum of SWNTs) on the covered surface of SWNTs.

Effectiveness of plain radiography in diagnosing hollow viscus perforation: study of 1,723 patients of perforation peritonitis.

Gastrointestinal perforations remain the most common cause of surgical pneumoperitoneum since time immemorial. The aim of this study was to find out the effectiveness of plain radiography in diagnosing hollow viscous perforation. A prospective analysis of a total of 1,723 patients of perforation peritonitis between January 2009 and June 2011, confirmed by exploratory laparotomy, was worked out in the study.

Periodontal diseases as an emerging potential risk factor for adverse pregnancy outcomes: A review of concepts.

Preterm birth is the leading perinatal problem with subsequent morbidity and mortality in developed as well as developing nations. Among the various possible environmental, genetic, demographic, psychosocial and obstetric risk factors responsible for premature labor, poor oral health with periodontal infection has also emerged as a potential and modifiable risk factor for preterm low birth weight babies. The infected periodontium is regarded as a reservoir for periodontopathic bacteria, mainly gram negative anaerobes that serve as a source of endotoxins and lipopolysaccharides, proinflammatory cytokines and prostaglandins that enhance uterine muscle contraction leading to preterm low birth weight.

Hyaluronic acid: a promising mediator for periodontal regeneration.

Hyaluronic acid (HA) is a natural-non sulphated high molecular weight glycosaminoglycan that forms a critical component of the extracellular matrix and contributes significantly to tissue hydrodynamics, cell migration and proliferation. The use of HA in the treatment of inflammatory process is established in medical areas such as orthopedics, dermatology and ophthalmology. In the field of dentistry, hyaluronate has shown anti-inflammatory, antiedematous and anti-bacterial effects for the treatment of gingivitis and periodontitis.

A relaxed implant bed: implants placed after two weeks of osteotomy with immediate loading: a one year clinical trial.

A waiting period of 2 weeks after osteotomy increases the surrounding tissue activity to its maximum level as collagen formation and neoangiogenesis represent a relaxed and acceptable implant bed configuration. The aim of the present study was a clinical and radiologic evaluation of early osteotomy with implant placement delayed for 2 weeks with immediate loading in the anterior and premolar region with minimally invasive approach. Seven GS II implants (Osstem) were placed in 6 patients.

Giant-cell tumors of the patella.

This study describes the clinical, radiographic, and histopathologic features, and discusses the management options of 11 cases of benign giant-cell tumors of the patella seen over 20 years. Fine needle aspiration cytology was a useful preoperative diagnostic tool. Ptellectomy and reconstruction of the extensor apparatus is the favored treatment option with curettage and bone grafting restricted to selected localized lesions.
