Clinical evaluation of platelet rich fibrin as barrier membrane in treatment of grade II furcation defects.

Background And Objectives: Various guided tissue regenerative procedures have been used in treatment of furcation defects. A combination of various graft materials and barrier membranes have been used over a period of time. The present study was designed to test whether autologous platelet-rich fibrin (PRF) can be effectively used as a barrier membrane along with porous hydroxyapatite (HA) bone graft in the treatment of Grade II furcation defects.

Seasonal Variations of Heavy Metals in the Soil Around a Coal-Fired Thermal Power Plant, South-West Coast of India.

This study focuses on seasonal variations of heavy metals in the soil around a coal fired thermal power plant in Udupi district, which is a densely populated town in the tropical southwest coast of India. This study, pertaining to 48 soil samples, collected during the pre-monsoon, early-monsoon, monsoon and post-monsoon seasons for one year, reveals that the chemistry of collected soil samples is influenced by non-pedogenic (anthropogenic) sources such as fly-ash deposition from the thermal power plant and vehicular emissions. This was concluded based on grouping of similar behaved elements through correlation-regression analysis.

Innovative use of laterally positioned periosteal pedicle graft for coverage of gingivitis artefacta.

There are many etiological factors for nonplaque-induced gingival diseases, out of which physical trauma due to psychiatric reasons leading to self-infliction is less studied upon. This case report presents one such case which has been successfully treated stepwise where psychological counseling was done to restrain from habit followed by using an innovative laterally positioned periosteal pedicle graft for dehiscence coverage.

Rock magnetic finger-printing of soil from a coal-fired thermal power plant.

We present seasonal rock magnetic data for 48 surficial soil samples collected seasonally around a coal-fired thermal power plant on the southwest coast of India to demonstrate how fly ash from the power plant is transported both spatially and seasonally. Sampling was carried out during pre-monsoon (March), early-monsoon (June), monsoon (September) and post-monsoon (December) seasons. Low- and high-frequency magnetic susceptibility (χlf and χhf), frequency-dependent magnetic susceptibility (χfd), χfd %, isothermal remanent magnetization (IRM), "hard" IRM (HIRM), saturation IRM (SIRM) and inter-parametric ratios were determined for the samples.

Evaluation of serum ceruloplasmin in aggressive and chronic periodontitis patients.

Background: Pro-inflammatory markers are seen to increase in inflammatory diseases like periodontitis. Detecting an increase in these markers is one of the diagnostic modality. One such marker, which can be detected, is the ceruloplasmin.
