[ 1 ] - Anticonvulsant Effects of New 1, 4-Dihydropyridine Derivatives Containing Imidazolyl Moiety Against Seizures Induced by Pentylenetetrazole and Maximal Electroshock in Mice

Epilepsy is a chronic disorder of the brain affecting around 50 million people in the world.Up to 30% of epileptic patients do not respond to available drugs and medical therapies. In thispaper, anticonvulsant screening of 10 synthesized new derivatives of 1, 4-dihydropyridine-3,5-dicarboxamides was performed.Anticonvulsant activity was evaluated by intravenous and intraperitoneal pentylenetetr...

[ 2 ] - Development of an RP-HPLC-UV method for simultaneous detection of nimodipine and its metabolite in cerebrospinal fluid of rat

A rapid, simple and reproducible HPLC method was developed and validated for the analysis of nimodipine (NM) and/or its metabolite, oxidized nimodipine (OX–NM) in rat cerebrospinal fluid (CSF) and artificial CSF. The NM and OX–NM were eluted in less than 10 min with no interferences from the endogenous CSF peaks. Analysis was carried out on a Eurospher Performance (RP-C18, 250 × 4.6 mm) column ...

[ 3 ] - Docetaxel loaded PEG-PLGA nanoparticles: optimized drug loading, in vitro cytotoxicity and in vivo antitumor effect

In this study a 3-factor, 3-level Box-Behnken design was used to prepare optimized docetaxel (DTX) loaded pegylated poly lactide-co-glycolide (PEG-PLGA) NPs with polymer concentration (X1), drug concentration (X2) and ratio of the organic to aqueous solvent (X3) as the independent variables and particle size (Y1), poly dispersity index (PDI) (Y2) and drug loading (Y3) as the responses. The cyto...

[ 7 ] - تجمع زیستی ویتامین D3 توسط باکتری لاکتوباسیلوس پلانتاروم و بهینه‌سازی آن با روش رویه پاسخ

زمینه و اهداف: اثر کمبود ویتامین D۳ درخطر ابتلای به بیماری‌هایی مانند نرمی استخوان، استئوپنی، پوکی استخوان و انواع سرطان، به‌خوبی شناخته‌شده است. سویه پروبیوتیک باکتری لاکتوباسیلوس پلانتاروم که بتواند ویتامین محلول در چربی D۳ را در توده زیستی خود ذخیره کند، علاوه بر اینکه می‌تواند زمینه‌ساز تولید محصولاتی با مزایای پروبیوتیک شود، احتمالاً اثرات نقص ویتامین D۳ را کاهش خواهد داد. مواد و روش کار: د...

[ 8 ] - Oliveria decumbens, a bioactive essential oil: Chemical composition and biological activities

Oliveria decumbens is an aromatic plant traditionally used for treatment of infections and gastrointestinal diseases. In the present study, the volatile oil of the plant was obtained by hydrodistillation and analyzed by GC-MS. In addition, antibacterial and anti-Helicobacter pylori activities of this essential oil were determined using disc diffusion and agar dilution methods, respectively. Ins...

[ 10 ] - Production of vitamin D3 enriched biomass of Saccharomyces cerevisiae as a potential food supplement: evaluation and optimization of culture conditions using Plackett–Burman and response surface methodological approaches

Vitamin D deficiency causes osteoporosis, osteopenia, fractures, rickets and more recently is linked with some chronic illnesses such as cancer. Because of the safety and probiotic properties of the yeast Saccharomyces cerevisiae, we hypothesized that yeast cells enriched with cholecalciferol (vitamin D3) could represent a solution for prevention or treatment of vitamin D deficiency. In this st...

[ 12 ] - Two Novel Compounds with Tri-aryl Structures as Effective Anti-Breast Cancer Candidates In-vivo

Prognosis of metastatic breast cancer is very poor which urges the necessity to develop novel potential drug candidates. We assessed two compounds with tri-aryl structures (A and B) for their potency to reduce primary breast tumor growth and lung metastasis in 4T1 mice model. MTT assay, 4T1 mammary mouse model and immunohistochemistry experiments were used in this study. In vitro results exhibi...
