Pharmaceuticals and personal care products and heavy metals in the Ganga River, India: Distribution, ecological and human health risk assessment.

In the present study, pharmaceuticals and personal care products (PPCPs), endocrine disrupting compounds (EDCs), and heavy metals (HMs), were measured in water and sediment of the Ganga River during summer and winter seasons for two consecutive years. Additionally, this study estimated the ecological and human health risks associated with PPCPs, EDCs, and HMs. HMs detected in the range of not detected (n.

Screening and analysis of specific language impairment in young children by analyzing the textures of speech signal.

A child having a delayed development in language skills without any reason is known to be suffering from specific language impairment (SLI). Unfortunately, almost 7% kindergarten children are reported with SLI in their childhood. The SLI could be treated if identified at an early stage, but diagnosing SLI at early stage is challenging.

Pathological nature of renal tumors - does size matter?

Introduction: We examined the relationship between the size and nature of renal masses in term of malignant potential, histological grading, pathological staging and presence of necrosis and sarcomatoid changes.

Materials And Methods: Retrospectively, we reviewed 323 consecutive nephrectomies between 2000 and 2010. Final pathology was correlated with tumour size.

Concentration dependent switch in the kinetic pathway of lysozyme fibrillation: Spectroscopic and microscopic analysis.

Formation of amyloid fibrils is found to be a general tendency of many proteins. Investigating the kinetic mechanisms and structural features of the intermediates and the final fibrillar state is essential to understand their role in amyloid diseases. Lysozyme, a notable model protein for amyloidogenic studies, readily formed fibrils in vitro at neutral pH in the presence of urea.

Comparative evaluation of a bioabsorbable collagen membrane and connective tissue graft in the treatment of localized gingival recession: A clinical study.

Background: Gingival recession (GR) can result in root sensitivity, esthetic concern to the patient, and predilection to root caries. The purpose of this randomized clinical study was to evaluate (1) the effect of guided tissue regeneration (GTR) procedure using a bioabsorbable collagen membrane, in comparison to autogenous subepithelial connective tissue graft (SCTG) for root coverage in localized gingival recession defects; and (2) the change in width of keratinized gingiva following these two procedures.

Materials And Methods: A total of 10 cases, showing at least two localized Miller's Class I or Class II gingival recession, participated in this study.

A modified double pedicle graft technique and other mucogingival interceptive surgeries for the management of impacted teeth: a case series.

Maxillary canine is one of the most common teeth that are impacted. This accounts for 1-2% of all patients who attend orthodontic treatment. The key to achieve maximal eruption of these teeth is their surgical exposure and the role of periodontist in such situations is to provide a functional and satisfactory width of attached gingiva on the labial surface.

Treatment of gingival pigmentation: a case series.

A smile expresses a feeling of joy, success, sensuality, affection and courtesy, and reveals self confidence and kindness. The harmony of the smile is determined not only by the shape, the position and the color of the teeth but also by the gingival tissues. Gingival health and appearance are essential components of an attractive smile.
