Abstract:

Human chorionic gonadotropin (HCG), a glycoprotein hormone with two nonidentical subunits, is produced by chorionic tissue in pregnant women and by neoplastic tissue containing chorionic elements. It is used in the treatment of male hypogonadism and female sub-fertility. Quantitation of HCG is used to monitor therapy, diagnose various disease states and diagnose and monitor pregnancy. Low levels of HCG in the early and late stages of pregnancy and in various disease states has prompted the development of extremely sensitive assay procedures. Clinically, radioimmunoassay methods are most frequ

Abstract:

To assess the significance of pollutants released into the environment it is necessary to determine both the extent of contamination and the biological effects they give rise to. This research is based on a tiered system, which commences with conventional analytical chemistry (gas chromatography), followed by the development, evaluation and application of rapid and simple immunochemical techniques and, finally, the integration of chemical and biological markers to assess pollution. GC-ECD/FID/MS have been used to investigate the status of chemical contamination of the Black Sea by organochlori

In North America it is still an investigational drug. Propafenone is a chiral drug and is used clinically in the racemic form. The enantiomers of numerous chiral drugs have been shown to differ in their disposition kinetics in the body due to their stereosele

Abstract:

Cromolyn sodium (CS) is a mast cell stabilizer which has been used to treat systemic mastocytosis, allergic- and exercise-induced asthma, and allergic reactions induced by atopic dermatitis. Presently, CS is administered orally and intranasally, and with a short half-life and poor absorption, 4 to 8 doses are required daily for treatment. Developing a transdermal product for CS would eliminate such drawbacks that lead to inconsistent patient dosing and provide sustained therapeutic effects when administered via skin. Our long-term goal is to determine the feasibility of delivering CS through s

Phenylephrine (PE) is the most commonly used over-the-counter nasal decongestant.

Abstract:

Propolis is an approved food additive containing flavonoids as a major active constituent. Variability has been found in the composition of propolis in distinctive regions and it was noticed that there are limitations in the analysis of propolis. In this study, the identification of ten flavonoids and residual antibiotics in propolis was investigated by using several liquid chromatography techniques, including reversed-phase high-performance liquid chromatography (RP-HPLC), microemulsion LC (MELC) and ultra-performance LC (UPLC). The ten flavonoids that were selected for this research include

Abstract:

Fatty acyl-Coenzyme As are metabolites of lipid anabolism and catabolism. A method was developed for their quantitation in extracts of cultured mammalian cells using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Palmitoyl-CoA (C16:0-CoA) is utilized for de novo sphingolipid biosynthesis catalyzed by serine palmitoyltransferase (SPT), which condenses palmitoyl-CoA and serine to form 3-ketosphinganine. After reduction to form sphinganine (Sa), dihydroceramide synthase (CerS) can N-acylate the Sa using a second fatty acyl-CoA molecule, forming dihydrocera

Abstract:

Congenital Adrenal Hyperplasia (CAH) encompasses several disorders related to disruptions in the adrenal steroid production pathway. These disruptions may cause virilization of the external female sex organs, incorrect gender assignment, precocious puberty, and in the most severe form, may cause life-threatening salt wasting and adrenal crisis if not detected and treated early in the newborn period. 17α-Hydroxyprogesterone (17-OHP) is the primary target for immunofluorescence detection of CAH from dried blood spots in newborn screening (NBS). Unfortunately, current immunoassay techniques for t

Abstract:

Polar organic compounds (POCs) are chemicals with polar functional groups in their structure. The functional groups make the compounds hydrophilic and less prone to partition with biota. However, the knowledge of their fate is limited due to difficulties associated with their measurements. Although, the persistence of POCs in the environment is generally low, they are considered to be semi-persistent compounds due to their continuous introduction to the environment via wastewater. Studies have shown that complex mixtures of POCs of different classes may have synergistic toxic effects on biota
