Material and Methods: After a liquid-liquid extraction of pharmaceutical products at acidic, neutral and basic pH with chloroform-isopropanol (9:1, v/v), the different steroids were separated by fused silica capillary column and detected by electron impact (EI)-MS in positive ionization mode. Results and Conclusion: The assay was validated in the range from 10 mg to 250 mg/g powder preparations and 0.02 mg to 200 mg/mL liquid preparations with good determination coefficients (r2 0.99) for the calibration curves. At three concentrations spanning the linear dynamic ranges of the calibration curves, mean recoveries were always higher than 90% and intra-assay and inter-assay precision and accuracy were always better than 15%. This method was successfully applied to the analysis of 15 pharmaceutical preparations sold by illegal sources. In only two cases the content was the one reported on the labels.

  • Daily Lifestyle Modifications to Improve Quality of Life And
    brain sciences Review Daily Lifestyle Modifications to Improve Quality of Life and Survival in Glioblastoma: A Review Sarah Travers and N. Scott Litofsky * Division of Neurosurgery, University of Missouri School of Medicine, Columbia, MO 65212, USA; [email protected] * Correspondence: [email protected] Abstract: Survival in glioblastoma remains poor despite advancements in standard-of-care treatment. Some patients wish to take a more active role in their cancer treatment by adopting daily lifestyle changes to improve their quality of life or overall survival. We review the available literature through PubMed and Google Scholar to identify laboratory animal studies, human studies, and ongoing clinical trials. We discuss which health habits patients adopt and which have the most promise in glioblastoma. While results of clinical trials available on these topics are limited, dietary restrictions, exercise, use of supplements and cannabis, and smoking cessation all show some benefit in the comprehensive treatment of glioblastoma. Marital status also has an impact on survival. Further clinical trials combining standard treatments with lifestyle modifications are necessary to quantify their survival advantages.

    ISSN: 0975-8585 Research Journal of Pharmaceutical, Biological and Chemical Sciences Formulation and Evaluation of Floating Drotaverine Hydrochloride Tablets Using Factorial Design Om Prakash*, S Saraf, M Rahman, Neeraj Agnihotri, and Vinay Pathak Department of Industrial chemistry, Integral University, Lucknow. Uttar Pradesh, India. ABSTRACT The main aim of this study was to optimize and evaluate the floating tablets of Drotaverine HCl that prolong the gastric residence time, increasing drug bioavailability and control pain for longer duration by oral administration. A floating drug delivery system(FDDS) was developed using gas forming agent like sodium bicarbonate, citric acid polymers like hydroxypropyl methyl cellulose(HPMC), Sod CMC, Carbopol-934P, PVP K-30. In 32 factorial design amount of HPMC(X1) and gas generating agents(X2) were selected as independent variable and % drug release for 30min,1h, 2h,4h,6h, 8h,12h, 16h , 24h and floating lag time (FLT) were taken as dependent variable. The floating tablet formulations were evaluated for Bulk density (gm/cm3), Tapped density(gm/cm3), Hausner ratio(HR), Carr index, Angle of repose, flow property, assay, in-vitro drug release, hardness, friability,weight variation. The results of in vitro release studies showed that the optimized formulation (F9) could sustain drug release (98.74%) for 24h and remain buoyant for more than 24h. The combination of hydrophilic (HPMC) and hydrophobic (carbopol-934P) polymer provides a better option for 24h release action, bioavailability, stability of tablets at 400C/75%RH, of optimized formulation was carried for one month and no significant change was observed. Keywords: floating drug delivery system(FDDS), Drotaverine HCl, gas generating agents, floating lag time (FLT), hydrophilic (HPMC) and hydrophobic (carbopol-934P) polymer.

    Product Information Boldenone Cypionate Item No. 15158 CAS Registry No.: 106505-90-2 O Formal Name: 17β-hydroxy-androsta-1,4-dien-3-one O cyclopentanepropionate MF: C27H38O3 FW: 410.6 H Purity: ≥95% Stability: ≥2 years at -20°C H H Supplied as: A crystalline solid λ O UV/Vis.: max: 244 nm Laboratory Procedures For long term storage, we suggest that boldenone cypionate be stored as supplied at -20°C. It should be stable for at least two years. Boldenone cypionate is supplied as a crystalline solid. A stock solution may be made by dissolving the boldenone cypionate in the solvent of choice. Boldenone cypionate is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide, which should be purged with an inert gas. The solubility of boldenone cypionate in these solvents is approximately 15, 5, and 25 mg/ml, respectively. Boldenone cypionate is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, boldenone cypionate should first be dissolved in ethanol and then diluted with the aqueous buffer of choice. Boldenone cypionate has a solubility of approximately 0.3 mg/ml in a 1:2 solution of ethanol:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day. Boldenone is an anabolic androgenic steroid and synthetic derivative of testosterone that was originally developed for veterinary use.1 It can increase nitrogen retention, protein synthesis, and appetite, and also stimulates the release of erythropoietin in the kidneys.1 Boldenone cypionate was synthesized as an ester of boldenone in an attempt to alter boldenone’s very long half-life.2 Anabolic androgenic steroid compounds such as boldenone cypionate have been used illicitly by bodybuilders and other athletes.3 This compound is intended for forensic and research purposes only.

Objectives: To suggest possible treatment strategies for non-binary transgender individuals with non-standardized requests and to emphasize the importance of a personalized clinical approach. Methods: A narrative review of pertinent literature on gender-affirming hormonal treatment in transgender persons was performed using PubMed. Results: New hormonal treatment regimens outside those reported in current guidelines should be considered for non-binary transgender individuals, in order to improve psychological well-being and quality of life. In the present review we suggested the use of hormonal and non-hormonal compounds, which—based on their mechanism of action—could be used in these cases depending on clients’ requests. Conclusion: Requests for an individualized hormonal treatment in non-binary transgender individuals represent a future challenge for professionals managing transgender health care. For each case, clinicians should balance the benefits and risks of a personalized non-standardized treatment, actively involving the person in decisions regarding hormonal treatment.

Br J Sports Med 2004;38:253–259. doi: 10.1136/bjsm.2003.000199 Objectives: To investigate the effects of two different regimens of androgenic-anabolic steroid (AAS) administration on serum lipid and lipoproteins, and recovery of these variables after drug cessation, as indicators of the risk for cardiovascular disease in healthy male strength athletes. Methods: In a non-blinded study (study 1) serum lipoproteins and lipids were assessed in 19 subjects who self administered AASs for eight or 14 weeks, and in 16 non-using volunteers. In a randomised double blind, placebo controlled design, the effects of intramuscular administration of nandrolone decanoate (200 mg/week) for eight weeks on the same variables in 16 bodybuilders were studied (study 2). Fasting serum concentrations of total cholesterol, triglycerides, HDL-cholesterol (HDL-C), HDL2-cholesterol (HDL2- C), HDL3-cholesterol (HDL3-C), apolipoprotein A1 (Apo-A1), apolipoprotein B (Apo-B), and lipoprotein (a) (Lp(a)) were determined. Results: In study 1 AAS administration led to decreases in serum concentrations of HDL-C (from 1.08 (0.30) to 0.43 (0.22) mmol/l), HDL2-C (from 0.21 (0.18) to 0.05 (0.03) mmol/l), HDL3-C (from 0.87 (0.24) to 0.40 (0.20) mmol/l, and Apo-A1 (from 1.41 (0.27) to 0.71 (0.34) g/l), whereas Apo-B increased from 0.96 (0.13) to 1.32 (0.28) g/l.
