Identification of Compounds Contributing to Glucocorticoid Activity in Indoor Dust Supported by Orthogonal Fractionation.

Indoor dust contains various endocrine-disrupting contaminants, yet the effect drivers of observed glucocorticoid activity are completely unknown. This study conducted an effect-directed analysis using orthogonal fractionation to identify effect drivers of glucocorticoid activity in indoor dust. After the detection of bioactivity using a human cell line stably transfected with a reporter gene, the sample underwent parallel HPLC fractionations with octadecyl, pentafluorophenyl, and aminopropyl columns to obtain orthogonal fractions.

Primary ciliary dyskinesia as a rare cause of male infertility: case report and literature overview.

Background: Primary ciliary dyskinesia (PCD) is a heterogenous disease caused by mutations of miscellaneous genes which physiologically play an important role in proper structure and/or function of various cellular cilia including sperm flagella. Besides male infertility, the typical phenotypes, based on decreased mucociliary clearance, are lifelong respiratory issues, i.e.

Patient Perceptions of Radiation Therapy Prior to Initial Consultation With a Radiation Oncologist.

Purpose: There are currently limited data regarding patient perceptions and fears related to radiation therapy (RT). This study sought to identify and quantify patient concerns regarding RT and to determine the potential value of assessing these expectations prior to initial consultation.

Methods And Materials: Patients with no prior history of RT were invited to complete an investigator-developed anonymous electronic survey prior to consultation.

Adiposity and body fat distribution based on skinfold thicknesses and body circumferences in Czech preschool children, secular changes.

Background: The long-standing widespread prevalence of obesity includes issues of its evaluation. Nutritional status may be assessed using various tools and methods; among others simple anthropometric measurements are well established. Widely used body mass index (BMI), presents an obstacle of needing to calculate a standard deviation score (SD) for correct use in the child population.
