OBJECTIVES: Breast cancer is a leading cause of death among women in both developed and Third World countries. Fucoidan is a natural plant product produced by brown seaweeds with proven anticancer potential. This study determined the cytotoxic, apoptotic and cell cycle effects of fucoidan alone and in combination with first-line anticancer drugs (cisplatin, doxorubicin and taxol) in MCF-7 breast cancer cells and non-malignant MCF-12A breast epithelial cells as control. METHODS: Cytotoxicity was evaluated using the MTT reduction assay...

BACKGROUND: Prominent among all the organisms that have a potential value for the pro-duction of new medicines, are endophytes, fungi and bacteria that live inside plants without harming them. In this study, a total lyophilized extract (TLE) of Paenibacillus polymyxa RNC-D was used. The P. polymyxa lineages are known for their capacity to segregate a large number of extracellular enzymes and bioactive substances. METHODS: The TLE of Paenibacillus polymyxa RNC-D was tested in cell viability assays for cytotoxicity and cytokine production in BALB/3T3 and J774A...

BACKGROUND: Citrullus colocynthis (Linn.) Schrad. is an important medicinal plant belonging to family Cucurbitaceae. Cucurbitacin E glucoside (1) was isolated from Citrullus colocynthis fruits. A novel mono-ester of cucurbitacin-E and cinnamyl & caffeoyl-β- D- glucoside (2 and 3) were synthesized by reacting of cucurbitacin E glucoside with cinnamic and/or caffeic acid in presence of CHCl2 and K2CO3 stirring and with an ice-cooling state for 24h. Mass analyses of the isolated and purified compounds were determined...

BACKGROUND: Among the many researches on cellular uptake and intracellular trafficking pathways of αvβ3-targeted nanomedicines, a great portion of studies utilize serum-free medium to evaluate drug effects and cellular mechanisms in vitro. Serum free or not hasn't been paid much attention. METHODS: The aim of this study was to assess the impact of serum on αvβ3-mediated endocytosis and intracellular trafficking pathways. cRGDfK conjugated with Alexa Fluor® 555 was used to recognize αvβ3 integrins specifically...

BACKGROUND: Poor ovarian responders (POR) pose a challenge to a physicians' ability to choose a stimulation protocol that maximizes the number of oocytes harvested and their chances of conception with multiple protocols aimed at improving pregnancy rates in this poor prognosis population. The Bologna criteria standardized the diagnosis of POR and allows for a more homogenous patient population in clinical trials. METHODS: A structured review of the literature, which encompasses research on Bologna-defined POR, identified several proposed protocols to optimize pregnancy rates in poor responders...

BACKGROUND: Enterococcus faecalis 2001 is a probiotic lactic acid bacterium and has been used as a biological response modifier (BRM). From physiological limitation of bacterial preservation in storage and safety, the live E. faecalis 2001 has been heat-treated and the BRM components containing high level of β-glucan, named EF-2001, has been prepared. METHOD: The heat-treated EF-2001 has been examined for the antioxidative potential for radical scavenging and anti-tumor activities as well as immune-enhancing response in mice...

BACKGROUND: Connexin (Cx) proteins are the building blocks of gap junctions. Among these, Cx37 and Cx40 are expressed on vascular system and reported to have cardioprotective role. Linking polymorphisms in genes coding for Cx and coronary artery disease (CAD) risk showed conflicting results in different populations. None has been studied before in Egyptians. Therefore, the aims of this study were to investigate the influence of Cx37 C1019T and Cx40 A71G polymorphisms on the predisposition of acute myocardial infarction (AMI) in Egyptians, to study linkage disequilibrium (LD) and combined effects of single nucleotide polymorphisms (SNPs) and to correlate the genotypes with sVCAM-1 serum levels...

BACKGROUND: While there are guidelines for the use of intravenous immunoglobulins in children with Guillain-Barre syndrome and myasthenia gravis based on high-level evidence studies, data is fewer for the majority of neurologic disorders in this age group. Neuronal antibodies are detected in children with seizures of autoimmune etiology. Intravenous immunoglobulins with their broad immunomodulatory mechanism of action could be ideally effective in different forms of immune-dysregulated intractable epilepsies such as autoimmune epilepsy and autoimmune Rasmussen encephalitis...

BACKGROUND: For design of a subunit vaccine for tuberculosis, identification of antigenic T-cell epitope is of utmost importance. Several MHC prediction server are available that can accurately predict antigenic peptide of variable lengths. However, peptides predicted from one server not necessarily are predicted form another server, thus creating a confusing situation for scientists to choose a best epitope. METHOD: Keeping the above problem in mind, we developed a comprehensive database of peptides of Mycobacterial proteins...

BACKGROUND: Vaccine formulations may contain visible and/or subvisible particles, which can vary in both size and morphology. Extrinsic particles, which are particles not part of the product such as foreign contaminants, are generally considered undesirable and should be eliminated or controlled in injectable products. However, biological products, in particular vaccines, may also contain particles that are inherent to the product. Here we focus on the characterization of visible and subvisible particles in a live, replication-deficient viral vaccine candidate against HSV genital herpes in an early developmental stage...

BACKGROUND: The awareness of factors causing obesity and associated disorders has grown up in the last years from genome to a more complicated concept (developmental programming) in which prenatal and early-postnatal conditions markedly modify the phenotype and homeostasis of the individuals and determine juvenile growth, life-time fitness/obesity and disease risks. Experimentation in human beings is impeded by ethical issues plus inherent high variability and confounding factors (genetics, lifestyle and socioeconomic heterogeneity) and preclinical studies in adequate translational animal models are therefore decisive...

Background The use of GnRH analogue medication is essential in reproductive medicine to avoid premature ovulation by pituitary suppression for the duration of ovarian stimulation by gonadotrophins. The type of pituitary suppression by either GnRH agonist analogues versus GnRH antagonist analogues may result in different embryological hence clinical results. Preimplantation genetic diagnosis is a subtype of IVF in which embryos are created for genetic diagnosis of hereditary disorders in order to avoid genetically affected children...

BACKGROUND: Women of reproductive age diagnosed with cancer are often interested in preserving gametes or reproductive tissue that would allow for future genetic parenthood. Preservation of fertility is often accomplished in young cancer patients via ovarian stimulation followed by oocyte or embryo cryopreservation. Conventional stimulation protocols, however, require 2-4 weeks to complete ovarian stimulation, oocyte retrieval and possible fertilization. Such a strategy may not be feasible in patients requiring urgent cancer treatment...
