Low levels of hCG are known to be co-produced with FSH during reproductive aging (during peri-menopause and menopause). A missed period could be indicative of pregnancy or peri-menopause for woman in later reproductive life, so understanding the reference ranges for hCG is important. Introduction hCG assays have high sensitivity and specificity for pregnancy1 Low levels of hCG are known to ...
Background The onset of a woman's fertile phase can be identified by an increase in concentration of urinary metabolites of estradiol, including E1-3G (estrone-3-glucuronide). Home ovulation tests typically detect the lutenising hormone (LH) surge, which identifies the day before and day of ovulation. Some tests also measure E1-3G to identify the user's wider fertile phase. Such tests ...
And now to a story that is never far from the headlines. If is about an EPA – Registered herbicide that has been linked to kidney disease. This story demonstrates the extent that entities will go to protext their commercial interests. The story comes from the organisation Beyond Pesticides. (Beyond Pesticides, February 6, 2019) The American Association for the Advancement of Science (AAAS) ...
The World Health Organization suggests storing human urine for at least 6 months at 20 °C prior to application as fertilizer to reduce the potential health risks from pathogenic organisms. Such a storage condition for human urine, however, not only requires a long period of time and large space but also ignores the risk of nitrogen losses. In this study, human urine underwent thermal ...
General function and description: The sample (serum, blood, urine or any other aqueous solution) is filled in a plastic sample tube and cooled via a Peltier element. These are semiconductor devices, which become cold on one side and warm on the other when electrical current flows through. The cold side cools the sample whilst the heat from the warm side dissipates into the air by convection. ...
Exogenous growth promoters have been used in United States beef cattle production for over 50 years. The environmental fate and transport of steroid growth promoters suggest potential for endocrine disrupting effects among ecological receptors; however, the initial excretion of steroid metabolites from cattle administered growth promoters has not been well characterized. To better characterize ...
Abstract A liquid chromatographic method was developed to resolve a comprehensive set of metabolites of JWH-018 and JWH-073. In addition to the chromatographic analysis method, an extraction method was developed to recover a broad range of synthetic cannabinoid metabolites, including carboxylic acid metabolites that are not traditionally recovered using a high pH liquid/liquid extraction. The ...
This work is aimed to study the effect of diabetes on bone health and to evaluate the impact of feeding flaxseed oil on delaying osteoporosis. About 70 female albino rats were included; 30 were ovariectomised (ovx). Experimental diabetes was induced. Rats were classified in groups as control, sham, diabetic, diabetic received flaxseed oil in the diet, ovx, ovx-diabetic and ovx-diabetic received ...
The following samples were collected at pre-determined intervals for the determination of either CPF or its metabolite TCP: dosing solutions, wash-off fractions and urine samples collected up to 120 h after dosing. ...
High levels of fluoride (beyond 1.5 ppm) in ground water as source of drinking water are common in many parts of Andhra Pradesh, India, causing fluorosis. The study carried out in endemic Nalgonda District, Andhra Pradesh, has indicated that the fluoride-rich ground water present in the wells located down stream and close to the surface water bodies is getting diluted by the low-fluoride surface ...
