The first study reported for nasal brain drug delivery was in 1937. The uptake of nasal - brain drug delivery, has received a great deal of attention as a convenient, method for the systemic administration of drugs. Which are low less effective orally, and, only effective if administered by injection. Many well-known different pathways and routes for drug absorption via the nose are affected by various factors. Some of them are factors related to the natural physiology of the nose and mucociliary clearance, enzyme, blood flow in the nasal cavity, and diseases. The bio-fate of drugs instilled in nasal cavity, is mainly affected by the pharmaceutical and pharmacokinetic properties of the drugs Pharmaceutical nanoparticulate carriers, also
... Show MoreSimvastatin (SIM), is an inactive lactone, anti-hyperlipidemic drug. The drug belongs to the class II group according to the biopharmaceutical classification system (BCS) with low bioavailability due to its low solubility. Adsorption technique is an effective technique for improving the solubility and dissolution rate of poorly soluble drugs by using the mesoporous silica. The present study aims to enhance the solubility and dissolution rate of SIM using such technique. Soluplus® and poloxamer 407 were used as surfactants besides magnesium aluminum silicate (MAS) as adsorbent. All the MAS loading SIM formulations were prepared by the solvent evaporation method in different drug: adsorbent: surfactant weight ratios, then evaluated for th

It may completely halt the disease's progression in high-risk individuals and lower the risk of death and recurrence in premenopausal and postmenopausal women. Variations in tamoxifen responsiveness between individuals may be attributed to polymorphisms in the primary metabolizing enzyme CYP3A4. The wild genotype (GG) of rs35599367 was found to be most common in 100 female breast cancer patients who were hormone receptor positive and taking tamoxifen, according to the study. This genetic variation may have a significant impact, as the GG genotype is strongly linked to significantly lower leve

Liquiritin is one of the main flavonoids found in Glycyrrhiza glabra that has been shown to have several pharmacological effects, such as the antioxidant, anti-inflammatory, anti-tumor, cardiovascular protection, hepatoprotection, and attenuation of rheumatoid arthritis in experimental animals. The present study investigated the protective effect of liquiritin against diabetic nephropathy in high fat diet and streptozotocin (STZ) induced diabetes mellitus in male rats.
In the present study, the type 2 diabetes model was induced by feeding the animals with the high fat diet for four weeks, af

Show MoreCarnosine have several important biological activities, as implicated by its effects on several diseases such cardiovascular disease, diabetes mellitus, cancer and can play important role in improving the functional capability during ischemic circumstances. Carnosine levels in diabetes patients may be affected by genetic variants in the carnosinase-2 gene, which may also be linked to development of cardiovascular problems. The purpose of this study was to examine the impact of the Carnosinase-2 gene polymorphism SNP (rs 6566810) on serum levels of carnosine and carnosinase-2 and their relationship to CVD in type 2 diabetes (T2DM) patients with and without CVD compared to healthy controls
Genistein (GEN) is The major isoflavone found in soybeans, has a number of cardiovascular health benefits, Postmenopausal syndrome and osteoporosis. A direct flow injection analysis method for estimation of (GEN) in pure and supplements formulation . This system is based on diazotization coupling reactions between procaine penciline (PR) and genistein in basic medium, they formed yellow dyes have maximum absorption at 416 nm. Calibration curve were constructed over different GEN concentrations, linearity for GEN was 10-100 µg.mL-1 and detection limits of 1.51 ?g/mL. In the FIA technique, all analytical factors were analyzed and optimized. The established method was successfully used to determine GEN in the formulations of its supplement

Show MoreThe present study evaluates the effects of Ginkgo biloba extract as monotherapy on the glycemic status, insulin resistance (IR), body mass index (BMI), and visceral adiposity index (VAI), in addition to the inflammatory markers, oxidative status and leptin level in patients with metabolic syndrome in comparison with metformin.
The study is a randomized, double-blind pilot study conducted during the period May to September, 2020. Fifty patients were recruited in the study and they were allocated into two groups (25 per each group): Ginkgo biloba and Metformin groups, they received (120 mg Ginkgo biloba extract/ capsule) and (500 mg Metformin/ capsule) respectively; orally as a single dose for 90 days. Blood samples were taken at z

Show MoreThe purpose of present study is to evaluate the effect of co-administration of curcumin (CUR) at various doses on the pharmacokinetic (PK) profile of tacrolimus (TAC), a CYP 3A4 substrate in healthy male rabbits. Healthy male rabbits (n=18) were employed in an in vivo, parallel-randomized study. Three groups of rabbits were selected and separated: The rabbits in the first group (control group) received 1 mg/kg TAC orally. Blood samples (1.5-2 mL) were drawn from rabbits' ear marginal veins at the following time frames: 15.0, 30.0, 45.0, 60.0, 90.0, 120.0, 150.0, 180.0 and 300 minutes after TAC administration post dosing and analyzed by using a TAC chemiluminescent enzyme immunoassay (CLIA) detection kit.

Genetic components are identified to strongly effect bone mineral density, bone building and turnover, so they play an important role in determining risk of OP and fragility fractures. This study consists of patient and control group; Group A: (70) postmenopausal women with OP and osteopenia, Group B: (20) control group. five milliliters of blood sample were divided into three tubes; one tube (1ml) contain gel for obtain serum to measure glucose level, the others tubes containing ethylene-diamine-tetra-acetic acid (EDTA), in 2 tube 2ml stored in deep freeze at (–40
