Preparation and In Vitro and In Vivo Evaluation of a Testosterone Film Forming Gel for the Treatment of Hypoactive Sexual Desire Disorder in Women.

Hypoactive sexual desire disorder (HSDD) is one of the most common sexual complaints in women. Currently, there is an unmet need for a drug treatment for this disorder. The purpose of this study was to develop a testosterone (TS) film forming gel used for women to treat HSDD by measuring the tackiness, peel adhesion force, tensile strength, and elasticity of the formulation.

siRNA-based breast cancer therapy by suppressing 17β-hydroxysteroid dehydrogenase type 1 in an optimized xenograft cell and molecular biology model in vivo.

Purpose: Hormone-dependent breast cancer is the most common form of breast cancer, and inhibiting 17β-HSD1 can play an attractive role in decreasing estrogen and cancer cell proliferation. However, the majority of existing inhibitors have been developed from estrogens and inevitably possess residual estrogenicity. siRNA knockdown provides a highly specific way to block a targeted enzyme, being especially useful to avoid estrogenicity.

Enhanced Delivery of Imatinib into Vaginal Mucosa via a New Positively Charged Nanocrystal-Loaded in Situ Hydrogel Formulation for Treatment of Cervical Cancer.

The present study was carried out to investigate the potential of cationic functionalization on imatinib nanocrystals to improve the mucoadhesiveness and, thus, delivery to the lesion of cervicovaginal tumors. Amino-group-functionalized imatinib nanocrystals (NC@PDA-NH₂) were prepared with near-spheroid shape, nanoscale size distribution, positive zeta potential, and relatively high drug content with the aid of the polydopamine-coating technique. Efficient interaction between NC@PDA-NH₂ and mucin was proven by mucin adsorption which was related to the positive zeta-potential value of NC@PDA-NH₂ and the change in the size distribution on mixing of NC@PDA-NH₂ and mucin.

Fenofibrate modified-release pellets with lag phase and high oral bioavailability.

Purpose: Fenofibrate and statin combination therapy is highly recommended by the current clinical guidelines for treatment of mixed dyslipidemia. In this study, an innovative delayed-release preparation of fenofibrate was designed to reduce the risk of muscle toxicity, caused by simultaneous administration of this combination therapy, by altering the pharmacokinetic profile of fenofibrate, as well as to improve the oral bioavailability of the modified-release formulation.

Methods: Micronized fenofibrate was used to prepare drug-loaded cores via a powder layering process before multiparticulate pellet coating.

Effect of doxorubicin-induced ovarian toxicity on mouse ovarian granulosa cells.

The objective of this study was to identify the effect of doxorubicin-induced ovarian toxicity on mouse ovarian granulosa cells. After granulosa cells were treated with doxorubicin at the final concentrations of 0, 0.4, 0.

[Modification by wheat germ agglutinin delays the ocular elimination of liposome].

The purpose of this study is to explore the feasibility of wheat germ agglutinin (WGA) modified liposome as a vehicle for ophthalmic administration. Liposome loaded with 5-carboxyfluorescein (FAM) was prepared by lipid film hydration method. WGA was thiolated and then conjugated to the surface of the liposome via polyethylene glycol linker to constitute the WGA-modified and FAM-loaded liposome (WGA-LS/FAM).

Inhibitory potential of chlormadinone acetate (CMA) on five important UDP-glucuronosyltransferases in human liver.

Chlormadinone acetate (CMA), a derivative of 17-a-hydroxyprogesterone, has been widely used as an orally effective progestogen in hormone replacement therapy (HRT). Glucuronidation catalyzed by UDP-glucuronosyltransferases (UGTs) is one of the major steps responsible for the metabolism of many drugs, environmental chemicals and endogenous compounds. Pharmacokinetic behaviours of drugs could be altered by inhibition of these UGT isoforms, and the search for drugs that potentially inhibit these UGT isoforms is very significant from a clinical point of view.
