Abstract
Abnormalities of steroid biosynthesis and excretion are responsible for the development and prevention of endocrine disorders, such as metabolic syndromes, cancers, and neurodegenerative diseases. Due to their biochemical roles in endocrine system, qualitative and quantitative analysis of steroid hormones in various biological specimens is needed to elucidate their altered expression. Mass spectrometry (MS)-based steroid profiling can reveal the states of metabolites in biological systems and provide comprehensive insights by allowing comparisons between metabolites present in cells, tissues, or organisms. In addition, the activities of many enzymes related to steroid metabolism often lead to hormonal imbalances that have serious consequences, and which are responsible for the progress of hormone-dependent diseases. In contrast to immunoaffinity-based enzyme assays, MS-based methods are more reproducible in quantification. In particular, high-resolution gas chromatographic (GC) separation of steroids with similar chemical structures can be achieved to provide rapid and reproducible results with excellent purification. GC-MS profiling therefore has been widely used for steroid analysis, and offers the basis for techniques that can be applied to large-scale clinical studies. Recent advances in analytical technologies combined with inter-disciplinary strategies, such as physiology and bioinformatics, will help in understanding the biochemical roles of steroid hormones. Therefore, comprehensive analytical protocols in steroid analysis for different research purposes may contribute to the elucidation of complex metabolic processes relevant to steroid function in many endocrine disorders, and in the identification of diagnostic biomarkers.

Abstract
A method of steroid profiling, including androgens, progestins, corticoids and sterols, was developed to evaluate the concentrations of steroids as well as the activities of the enzymes responsible for steroidogenesis in hair by gas chromatography/mass spectrometry. The extraction efficiencies of steroids from the hair matrix were improved by ultrasonication for 1 h at 50 °C. The overall recoveries ranged from 71 to 132%, with a limit of quantification for all analytes ranging from 1 to 50 ng/g. The devised method was used to identify the metabolic changes for both male-pattern baldness (MPB) and the drug efficiency of dutasteride, which inhibits 5α-reductase. Increased dihydrotestosterone levels and the dihydrotestosterone/testosterone (DHT/T) ratio, which is responsible for the 5α-reductase activity, were observed in the MPB patients. A dutasteride treatment resulted in decreases in the DHT and 5α-androstanedione concentrations and DHT/T ratio in the hair samples. Hair steroid profiling reflects the sebaceous status in the scalp and may be useful for monitoring the metabolic responses to both the disease and drug actions.

Abstract
Background: While a number of different derivatization procedures for screening GC–MS analysis of prohibited substances are followed by doping control laboratories, a unified derivatization procedure for the GC–MS analysis of 190 different doping agents was developed. Results: Following preliminary experiments, a two-step derivatization procedure was selected. The evaluation of various silylation parameters, such as reagent composition, reaction time, reaction temperature, catalysts and microwave oven reaction time, for this procedure was carried out. Conclusion: The suitability of the developed procedure was demonstrated through application on urine samples at concentration levels of the minimum required performance limit for all tested substances. This new derivatization procedure, which significantly decreases time and cost, is suitable for a routine basis application.

Abstract
Abnormalities in steroid hormones are responsible for the development and prevention of endocrine diseases. Due to their biochemical roles in endocrine system, the quantitative evaluation of steroid hormones is needed to elucidate altered expression of steroids. Gas chromatographic-mass spectrometric (GC-MS) profiling of 70 urinary steroids, containing 22 androgens, 18 estrogens, 15 corticoids, 13 progestins, and 2 sterols, were validated and its quantitative data were visualized using hierarchically clustered heat maps to allow "steroid signatures". The devised method provided a good linearity (r(2) > 0.994) with the exception of cholesterol (r(2) = 0.983). Precisions (% CV) and accuracies (% bias) ranged from 0.9% to 11.2% and from 92% to 119%, respectively, for most steroids tested. To evaluate metabolic changes, this method was applied to urine samples obtained from 59 patients with benign prostatic hyperplasia (BPH) versus 41 healthy male subjects. Altered concentrations of urinary steroids found and heat maps produced during this 70-compound study showed also differences between the ratios of steroid precursors and their metabolites (representing enzyme activity). Heat maps showed that oxidoreductases clustered (5alpha-reductase, 3alpha-HSD, 3beta-HSD, and 17beta-HSD, except for 20alpha-HSD). These results support that data transformation is valid, since 5alpha-reductase is a marker of BPH and 17beta-HSD is positively expressed in prostate cells. Multitargeted profiling analysis of steroids generated quantitative results that help to explain correlations between enzyme activities. The data transformation and visualization described may to be found in the integration with the mining biomarkers of hormone-dependent diseases.

Abstract
An efficient analytical method for simultaneous determination of 12 SFEs in serum is described. The method involves solid-phase extraction to isolate of SFEs from interfering species, especially cholesteryl esters, conversion to trimethylsilyl (TMS) ether derivatives for the direct analysis by gas chromatography-mass spectrometry (GC-MS) using a high temperature MXT-1 (Silcosteel-treated stainless steel) capillary column. All SFEs as their TMS derivatives were well separated with excellent peak shapes within 12 min. Overall recoveries ranged from 88% to 119%, with a detection limits for SFEs ranged from 2 to 30 microg L(-1). The linearity as correlation coefficient was higher than 0.99 except for pregnenolone-3-arachidate (r(2)=0.98) in the concentration range of 5-3000 microg L(-1). Ten serum samples obtained from volunteers were also analyzed and quantitatively determined of DHEA-3-palmitate and pregnenolone-3-stearate in 1.8-1195.8 microg L(-1) concentration. The devised high temperature GC-MS method could be useful for identification of SFEs in biological specimens including serum.

Abstract
Since corticosteroid metabolism may be affected by disease states, the accurate and precise measurement of endogenous corticosteroids in urine is necessary to understand their biochemical roles. An efficient quantitative profiling of 21 endogenous corticosteroids in urine has been validated by liquid chromatography-tandem mass spectrometry (LC-MS/MS). After enzymatic hydrolysis with beta-glucuronidase, samples were purified using a solid-phase extraction cartridge and then separated through a sub-2 microm particle C18 column (2.1 mm x 50 mm, 1.9 microm) and quantified within 12.1 min using a triple quadrupole MS with electrospray ionization in positive ion mode. All corticosteroids resulted in the base-line separation, which is even achieved for stereo-isomers, such as alpha-/beta-cortol, alpha-/beta-cortolone, and allo-tetrahydrocortisol/tetrahydrocortisol. Overall recoveries ranged from 85% to 106% with limit of quantification ranged from 0.5 to 2.0 ng mL(-1) for the corticosteroids examined. The precision (% CV) and accuracy (% bias) of the assay were 1.7-7.8% and 95.1-105.4%, respectively, in 0.5-200 ng mL(-1) calibration ranges (r(2)>0.9903), for quality-control samples containing 21 endogenous corticosteroids at three different urinary concentrations. Clinical application included quantitative analysis from patients with both prostate cancer and benign prostatic hyperplasia with altered cortisol concentrations. The described LC-MS/MS method eliminates interference from other urine components, has excellent chromatographic resolution achieved by a small particle LC column with a sufficient sensitivity to allow the profiling of both gluco- and mineralo-corticosteroids at a time.

Abstract
Although the hydrophobic interaction-based solid-phase extraction (SPE) has been widely used, the extraction yields of steroids including androgens, estrogens, and corticoids were slightly different along with the physical and chemical properties of each molecule. A new SPE technique based on the formation of an inclusion complex with beta-cyclodextrin (betaCD) has been achieved for comprehensive sample purification in mass spectrometric analysis of 45 endogenous or synthetic androgens, 11 endogenous estrogens, and 21 corticoids. A copolymer of betaCD with epichlorohydrin was prepared by a cross-linking reaction followed by entrapment with 0.3M CaCl(2) to yield an improved SPE sorbent and the hydrolyzed urine samples were applied for purification. Steroidal compounds tested on the entrapped betaCD polymer were extracted with tetrahydrofuran and the overall recoveries ranged from 82% to 112% for 77 steroids in urine. Especially, the hydroxylated estrogens showed an excellent binding capacity (96-116% recovery) to betaCD through hydrogen bonding between their phenolic hydroxyl and exterior hydroxyl groups. A comparison between SPE methods with betaCD and Oasis HLB as a conventional cartridge showed that the extraction efficiency of polar steroids was significantly increased in the betaCD experiment, which has no connection with different polarity of steroid molecules. Due to its multi-functional mechanism derived from molecular inclusion and chemical interactions, this new SPE sorbent resulted in better selectivity and extraction efficiency than that obtained using the conventionally used hydrophobicity-based SPE method.
