The "energy gap law" for mid-infrared nanocrystals.

Colloidal quantum dots are of increasing interest for mid-infrared detection and emission, but device performances will vastly benefit from reducing the non-radiative recombination. Empirically, the photoluminescence quantum yield decreases exponentially toward the mid-infrared, which appears similar to the energy gap law known for molecular fluorescence in the near-infrared. For molecules, the mechanism is electron-vibration coupling and fast internal vibrational relaxation.

Bright Fluorophores in the Second Near-Infrared Window: HgSe/CdSe Quantum Dots.

Fluorophores emitting in the NIR-IIb wavelength range (1.5-1.7 μm) show great potential for bioimaging due to their large tissue penetration.

Toward Bright Mid-Infrared Emitters: Thick-Shell n-Type HgSe/CdS Nanocrystals.

A procedure is developed for the growth of thick, conformal CdS shells that preserve the optical properties of 5 nm HgSe cores. The n-doping of the HgSe/CdS core/shell particles is quantitatively tuned through a simple postsynthetic Cd treatment, while the doping is monitored via the intraband optical absorption at 5 μm wavelength. Photoluminescence lifetime and quantum yield measurements show that the CdS shell greatly increases the intraband emission intensity.

Comparative Evaluation of Instrumentation Time, Obturation Time, and Radiographic Quality of Obturation Using Two Rotary Systems and Manual Technique for Primary Molar Pulpectomies - Study.

Background: Ideal pulpectomy for primary dentition demands fast, simple procedures, with short treatment times and minimal appointments. Recently, exclusive pediatric rotary files are available for use in primary teeth. There is a paucity of literature on the clinical efficacy of pediatric rotary files.

Comparative evaluation of salivary zinc concentration in autistic and healthy children in mixed dentition age group-pilot study.

Context: Autism prevalence is increasing, with current estimates at 1/68-1/50 individuals diagnosed with autism. Diagnosis is based on behavioral assessments. Early diagnosis and intervention are known to greatly improve functional outcomes in people with autism.

Safety and efficacy of tamsulosin, alfuzosin or silodosin as monotherapy for LUTS in BPH - a double-blind randomized trial.

Introduction: Currently alpha1-adrenoceptor blockers (AB) are widely used as first-line therapy to improve lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). We compared the efficacy and safety profile of tamsulosin, alfuzosin and silodosin in LUTS due to BPH.

Material And Methods: Consecutive consenting male patients (N = 269) undergoing medical management of BPH with AB from February 2012 to October 2015 were enrolled.

Anatrophic Nephrolithotomy in the Management of Large Staghorn Calculi - A Single Centre Experience.

Introduction: With advances in endourology, open stone surgery for staghorn calculi has markedly diminished. Anatrophic Nephrolithotomy (AN) is performed for complex staghorn stones which cannot be cleared by a reasonable number of Percutaneous Nephrolithotomy (PNL) attempts.

Aim: To assess the indications and outcomes of AN in the modern era.

Comparison of efficacy of three chemotherapeutic agents on count in plaque and saliva: A randomized controlled triple blind study.

Background: There is a need for exploration of the role of chemotherapeutic agents and its role in the prevention of early childhood caries (ECC) and its recurrence.

Aim: The aim of this study was two-fold: (1) To compare the antimicrobial efficacy of three commonly used chemotherapeutic agents in the prevention of ECC in comparison with a control and (2) To ascertain the role of chemotherapeutic agents in the prevention of ECC.

Materials And Methods: Sixty children with ECC in the age group 3-6 years were randomly allocated into four groups.

UWIN (Urgency, Weak stream, Incomplete Void, Nocturia) Score for Assessment of Lower Urinary Tract Symptoms: Could it Replace the American Urology Association Symptom Index Score? An Open Label Randomized Cross over Trial.

Objective: The American Urology Association symptom index (AUASI) is the most accepted tool to assess lower urinary tract symptoms (LUTS). UWIN (urgency, weak stream, incomplete void, nocturia) score is a simplified questionnaire with fewer and more distinctive options omitting three questions from AUASI. We sought to identify if UWIN is equally efficient in capturing LUTS and could replace the gold-standard AUASI.

Knowledge, Attitude and Practice of Paediatricians toward Long-Term Liquid Medicaments Associated Oral Health.

Background: A pediatrician is a primary care physician who deals with the medical care of infants, children and adolescents. Oral health care for the subgroups detailed is certainly substantiated as an integral part of general health. There are conflicting results presented till date on the subject of knowledge, attitude and practice (KAP) of pediatricians on the consumption of pediatric liquid medicaments and the results can be divergent based on the geographical adjustments specifically with significance for industrial areas.

Comparative evaluation of cariogenic and erosive potential of commonly prescribed pediatric liquid medicaments: an in vitro study.

Introduction: Liquid oral medicines being the most accepted form of medication in children are frequently prescribed. The harmful effects of these liquid medicaments on a child's dental health are not known to many. The present study aimed to evaluate and compare the cariogenic and erosive potential of 5 most commonly prescribed pediatric liquid medicaments (PLM) in Pimpri Chinchwad and Pune city, Pune district.

Lingual versus buccal mucosa graft urethroplasty for anterior urethral stricture: a prospective comparative analysis.

Objective: To compare lingual and buccal mucosa graft urethroplasty for anterior urethral stricture with respect to intraoperative, postoperative parameters and urethroplasty outcome.

Methods: From January 2011 to December 2011, a total of 30 patients with anterior urethral stricture whereas group 2 underwent dorsal onlay buccal mucosa graft urethroplasty. Patients were evaluated for postoperative, tongue protrusion, oral opening, and difficulty in speech and swallowing pain score.
