Assessment of seasonal variability of PM, BC and UFP levels at a highway toll stations and their associated health risks.

As a part of their occupation, workers at toll stations are exposed to traffic emissions during the working shift, which sometimes stretches to 12 h. To assess the exposure and subsequent health risk of these workers, a study was performed on a highway toll station in India. PM, PM, PM, BC and UFP concentration were determined inside a toll collectors' cabin and outside in a free-flowing traffic section (125 m from the toll cabin).

Chemotherapy-associated oral complications in a south Indian population: a cross-sectional study.

Over the years, chemotherapy (CT) has evolved as an essential therapeutic modality for cancer, with oral manifestations frequently encountered as complications of cancer CT. Our study aimed to assess the prevalence of oral complications during CT and evaluate the significance of independent risk factors (age, gender, socio-economic status, oral hygiene practices etc). A cross-sectional study was carried out in a tertiary cancer hospital in Bhubaneswar, Odisha, India, in which a total of 138 hospitalized patients undergoing CT and fulfilling the inclusion and exclusion criteria were included.

Immunohistochemical expression of human telomerase reverse transcriptase in oral cancer and precancer: A case-control study.

Introduction: Telomere Length is critically important in normal cells and telomere shortening in combination with other oncogenic changes- promotes genome instability, potentially stimulating initiation of the early stages of cancer.

Aim: The present study was carried out to detect human telomerase reverse transcriptase expression in oral cancer and pre-cancerous lesions by immunohistochemistry.

Materials And Methods: An observational study was planned in which a total of 45 biopsy specimen of oral mucosa was obtained.
