There have been various laboratory methods for the microbiological diagnosis of periodontal disease. However, there have been some disadvantages in these methods. In this study of the application of a chair-side test for microbiological diagnosis, the activity of peptidases in periodontal pockets of patients was examined by using the assay system SK-013. SK-013 consists of synthetic substrates ...

In the whole world, most of air polluted cities were normalized during COVID-19 lockdown but after lockdown, pollution is continuously increasing day by day. present study, we assessed quality at selected sites Jaipur city from October 2020 to February 2021 quantify enhancement in pollution. The obtained data was processed using index (AQI), principal component analysis (PCA) and pearson correl...

[1] Pinatubo’s 15 June 1991 eruption was Earth’s largest of the last 25 years, and it formed a substantial volcanic cloud. We present results of analysis of satellite-based infrared remote sensing using Advanced Very High Resolution Radiometer (AVHRR) and TIROS Operational Vertical Sounder/High Resolution Infrared Radiation Sounder/2 (TOVS/HIRS/2) sensors, during the first few days of atmospher...

Sulphur dioxide (SO2) has been used for centuries to minimize color in food processing and fruit and vegetable storage. In the sugar industry, it is used routinely by sugar beet processors to reduce and prevent color formation in white refined sugar. Sugarcane processors throughout the world use SO2 to produce plantation white sugars. This study was undertaken to determine the effect of SO2 on ...

[1] Long-range transport of sulfur dioxide (SO2) from east Asia to the central North Pacific troposphere was observed on transit flights during the NASA Transport and Chemical Evolution over the Pacific mission. A series of SO2-enhanced layers above the boundary layer was observed during these flights. The significant features included enhanced SO2 layers associated with low water vapor and low...

This paper presents results of measurements of tropospheric sulphur dioxide (SO2) from satellite over China during 2004e2009. SCIAMACHY/ENVISAT SO2 data products have been validated by ground based remote sensing instrument MAXDOAS in China, and with predictions of the atmospheric model GEOSeChem. The spatial and temporal distribution of tropospheric SO2 over China is discussed in this study. T...

To assess effects of sodium fluoride and sulfur dioxide on oxidative stress and antioxidant defenses in the testes, 96 sexually mature male Wistar rats were divided randomly into four groups of twenty-four rats each. One group of rats was left untreated as controls, and the other three groups were administered, respectively, for eight consecutive weeks, 100 mg NaF/L (45 mg F–/L) in their drinki...

The suitability of individual MAb for application in vivo should be carefully confirmed. The monoclonal antibody GL-013, with specific binding reactivity in vitro to human tumors of the gastrointestinal tract, was radioiodinated and injected intraperitoneally into nude mice bearing human gastric carcinoma xenografts SY 86 B (moderately differentiated glandular adenocarcinoma) and SY 86 D (signe...

A green photoelectrochemical (PEC) process with simultaneous SO2 removal and H2 production has attracted an increasing attention. The proposed process uses flue gas SO2 to improve H2 production. The improvement of the efficiency of this process is necessary before it can become industrial viable. Herein, we reported a Mo modified BiVO4 photocatalysts for a simultaneous SO2 removal and H2 produc...

Photoacoustic (PA) imaging is capable of probing blood oxygen saturation (sO2), which has been shown to correlate with tissue hypoxia, a promising cancer biomarker. However, wavelength-dependent local fluence changes can compromise sO2 estimation accuracy in tissue. This work investigates using PA imaging with interstitial irradiation and local fluence correction to assess precision and accurac...
