this study investigated the relationships between nutrients and chlorophyll, a concentration in the international alma gol wetland. chlorophyll a is the major photosynthetic pigment in lots of phytoplanktons and has been used as a trophy index in aquatic ecosystems. water samples were collected fortnightly from five stations in the wetland during summer and autumn. chlorophyll-a ranged between ...

This study investigated the nitrifying community structure in a single-stage submerged attached-growth bioreactor (SAGB) that successfully achieved stable nitrogen removal over nitrite of a high-strength ammonia wastewater. The reactor was operated with intermittent aeration and external carbon addition (methanol). With influent ammonia and total Kjeldahl nitrogen ranging from 537 to 968 mg/L a...

BACKGROUND The relationship between inducible nitric oxide synthatase activity and disease severity in leptospirosis is unclear. Nitric oxide is converted to nitrites and nitrates, thus nitrite and nitrate levels (NOx) in serum are considered surrogate markers for nitric oxide. NOx are excreted through the kidneys, and elimination is diminished in renal impairment. We assessed the correlation o...

Objective(s):To know whether Scurrula atropurpurea is able to modulate total plasma nitrate/nitrite levels, decrease endothelial damage, and increase endothelial progenitor cells (EPCs) in hypertensive rats. Materials and Methods: The rats were divided in 5 groups: control (normotensive) group, Desoxy cortico sterone (DOCA)-salt hypertensive group, and three DOCA-salt hypertensive groups. All 5...

Pastırma, a dry-cured meat product, is produced from the whole muscle and/or muscles obtained from certain parts of beef and water buffalo carcasses. The purpose of this study was to determine the effects of different levels of sodium nitrite on changes in the physicochemical and microbial quality during the production of pastırma. The changes in residual nitrite, salt, pH, moisture, thiobarbut...

OBJECTIVE This is the first study in China to examine the use of nitrite inhalants and its correlates among men who have sex with men (MSM) in Beijing, China. METHODS A cross-sectional survey was conducted in 2012. Structured interviews collected data on demographics, sexual and drug use behaviors, and the use of HIV services. Blood specimens were collected and tested for HIV and syphilis. ...
