Links between airborne microbiome, meteorology, and chemical composition in northwestern Turkey.

The composition of atmospheric aerosols is dynamic and influenced by their emission sources, organic and inorganic composition, transport pathways, chemical and physical processes, microorganisms' content and more. Characterization of such factors can improve the ability to evaluate air quality and health risks under different atmospheric scenarios. Here we investigate the microbial composition of the atmospheric particulate matter (<10 μm; PM), sampled in Bolu, Turkey, and the linkage to the chemical composition changes, and different environmental factors.

Photocatalytic degradation of yellow 2G dye using titanium dioxide/ultraviolet A light through a Box-Behnken experimental design: Optimization and kinetic study.

Yellow 2G (Y2G), a type of anionic, synthetic monoazo dye that is widely used in household applications, textiles, and food industries, has been found to have cardiovascular and neurological effects on all living beings. In the present study, heterogeneous photocatalytic degradation of commercial Y2G was conducted using pure titanium dioxide (TiO) in a batch reactor system under ultraviolet A (UVA) light for 180 min. TiO dosage, pH, and initial Y2G concentration were the three experimental parameters selected and studied to obtain preliminary information about the photocatalytic activities within a specified range.

Impact of treatment with metformin on adipokines in patients with polycystic ovary syndrome.

Background: Adipose tissue synthesizes various adipokines such as resistin, adiponectin and visfatin, which have an effect on insulin resistance. This study was designed to show the effect of metformin, one of the most important drugs used to reduce insulin resistance in patients with polycystic ovary syndrome (PCOS), on these adipokines.

Methods: The study group consisted of 24 women with PCOS and 25 healthy, age- and weight-matched, normally menstruating women.

Plasma visfatin level in women with polycystic ovary syndrome.

Objective: The aim of this study is to compare the serum level of visfatin between patients with polycystic ovary syndrome (PCOS) and control subjects matched for age and body mass index (BMI) and to assess the possible correlations of visfatin to the hormonal and metabolic parameters of the syndrome.

Material And Method: Fifty-five patients with PCOS diagnosis composed of 25 obese, 13 overweight, 17 normal weight subjects and 49 women without concomitant disease matched for age and BMI were included in this study.

Results: Serum visfatin levels were similar in normal weight PCOS and control group.

Isolated bladder aspergillosis as the primary presentation of non-oliguric acute renal failure.

A 70-year-old male patient with diabetes mellitus presented to our hospital with acute obstructive non-oliguric renal failure. Abdominal CT revealed obstructive hydronephrosis and irregular thickening of the bladder wall. Upon cystoscopy, samples of tissue were taken and found to be positive for Aspergillus spp.
