A simple and highly sensitive method that involves miniaturized hollow fiber assisted liquid-phase microextraction (HF-LPME) with in situ acyl derivatization and GC-MS was developed for the determination of benzophenone (BP) and related compounds in human urine samples. The limits of detection (S/N = 3) and quantification (S/N > 10) of BPs in human urine samples are 0.01 to 0.05 and 0.05 to 0.2...
Human urine was used as a fertilizer in cabbage cultivation and compared with industrial fertilizer and nonfertilizer treatments. Urine achieved equal fertilizer value to industrial fertilizer when both were used at a dose of 180 kg N/ha. Growth, biomass, and levels of chloride were slightly higher in urine-fertilized cabbage than with industrial-fertilized cabbage but clearly differed from non...
BACKGROUND Early life exposure to inorganic arsenic may be related to adverse health effects in later life. However, there are few data on postnatal arsenic exposure via human milk. In this study, we aimed to determine arsenic levels in human milk and the correlation between arsenic in human milk and arsenic in mothers and infants urine. METHODS Between March 2011 and March 2012, this prospec...
Background: Urinary tract infection (UTI) is one of the most common human bacterial infections. The frequent use of antibiotics is associated with increased resistance of many bacterial agents to the treatment.Materials and Methods: A total of 9456 urine specimens were collected from patients referring to Pol-e Dokhtar health centers. All urine samples were inoculated on blood agar plates...
The inhibitory effect of two kinds of Kampou medicine, Chorei-to and Gorei-san, on calcium oxalate crystallization in human urine, was examined. Chorei-to or Gorei-san was administered to 15 healthy male volunteers for three consecutive days under normal dietary conditions and 24-hour urine samples were collected before and after the administration. Urinary parameters including calcium, phospho...
The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two s...
Closing the human nutrient cycle with decentralized urine separation would help to achieve progress in food security and water protection – especially poor countries. For this, radical innovation is needed along whole sanitation value chain.
BACKGROUND Variation in different urinary measurements for evaluation of iodine status is of concern to clinicians and researchers. OBJECTIVE This study evaluated variations between urine iodine concentration (UIC), spot and 24-h urine sample creatinine concentrations, and 24-h urine iodine excretion (24-h UIE) in repeated samples from school-age children. METHODS Urine samples (24 h and mo...
Human serum albumin (HSA) is a broadly used biomarker for the diagnosis of various diseases such as chronic kidney disease. Here, fluorescent probe TC426 with aggregation-induced emission (AIE) characteristics reported sensitive and specific HSA. This non-emissive in aqueous solution, meanwhile it shows bright fluorescence upon interacting HSA, which makes applicable detecting HSA high signal t...
We have studied the kinetics of oxalate-induced turbidity in fresh human urine and artificial urine. Assays are performed in 96-well plates, which allows many oxalate concentrations to be studied, repeatedly, in a short time. The metastable limit is defined in terms of the lowest oxalate concentration that gives a rate of change of attenuance significantly greater than the control. Interpretati...
