Introduction: Several recent studies have shown that the role of cyclooxygenase 2 (COX-2) in carcinogenesis has become more evident. It affects angiogenesis, apoptosis, and invasion, and plays a key role in the production of carcinogens. It has also been reported that COX-2 inhibitors such as celecoxib (CLX) might play an effective role in preventing cancer formation and progression. Formulation of CLX into nanovesicles is a promising technique to improve its bioavailability and anticancer efficacy. Aim: The aim of this study is to optimize and evaluate the anticancer efficacy of CLX-loaded in-situ provesicular powder composed of surfactants and fatty alcohol-based novel …

Glimepiride is an antidiabetic drug which is one of the third generation sulfonylureas. It belongs to class II, according to the BCS (Biopharmaceutical Classification System), which is characterized by low solubility and high permeability. The aim of this work was to formulate glimepiride as solid dispersion using water-soluble carriers to enhance its aqueous solubility and thus enhance its bioavailability. Nine formulations of glimepiride solid dispersion were prepared by a solvent evaporation technique using three different carriers (mannitol, polyethylene glycol 6000, and β-cyclodextrin) with three different drug carrier ratio (1:1, 1:3, and 1:6). Formulation variables were optimized using 32 full factorial …
Polyphenols Profile Of Pomegranate Leaves And Their Role In Green Synthesis Of Silver Nanoparticles, Noha Swilam, Khaled Nematallah
Polyphenols Profile Of Pomegranate Leaves And Their Role In Green Synthesis Of Silver Nanoparticles, Noha Swilam, Khaled Nematallah
Pharmacy
The current study reports on polyphenols profile of pomegranate leaves (PL) Punica granatum grown in Egypt and exhibiting their role in development of an eco-friendly method of green synthesis of silver nanoparticles (AgNPs). PL aqueous alcohol extract was fractionated, the major phenolic compound was isolated from the polyphenols rich fraction (ethyl acetate fraction) and identified by conventional and spectroscopic methods of analysis as ellagic acid. Furthermore, the fraction was standardized and analysed using UPLC-PDA-UV and LC–MS-MS techniques revealing tentative identification of 23 polyphenolic compounds, quantifying ellagic acid as 43.14 ± 0.57 μg/mg of the fraction. AgNPs were successfully synthesized with …
Covid-19 Vaccination Clinical Trials Should Consider Multiple Doses Of Bcg, Bassam M. Ayoub
Covid-19 Vaccination Clinical Trials Should Consider Multiple Doses Of Bcg, Bassam M. Ayoub

Vaccine repositioning is a hot research topic as an alternative to the traditional vaccine approach, which is a costly and time-consuming process due to the availability of previous safety and toxicology data. Multiple-dose BCG vaccine repurposing for COVID-19 will be an uprising breakthrough of vaccine discovery with safer outcomes. BCG induces cross-protection that might not be related to the target disease as innate immune cells, including monocytes and natural killer cells, contribute to this immune protection as known as “trained immunity” (Covián et al. 2019). BCG had multifaceted protection against TB, leprosy, and heterogeneous pathogens (Yamazaki-Nakashimada et al. 2020). Moreover, …

Xanthones, polyphenolic compounds, are one of the most important classes in natural products, as they exhibit variety of pharmacological and health benefits, i.e., anti-obesity, antidiabetic, antioxidant, anti-Alzheimer, anti-inflammatory, and anticancer. Xanthones can be found in higher plants that are used as food sources.
