BACKGROUND: Prostate cancer (PC) constitutes a heterogeneous group of diseases with high prevalence rates that are still increasing, particularly in western countries. Since 1980, prostate specific antigen (PSA) and other diagnostic approaches have been used for PC screening; however, some of these approaches are often deemed painful and cause invasive damage of tissue. Therefore, molecular approaches to PC diagnosis are attracting increasing attention, potentially providing patients with less stressful situations and providing better diagnoses and even prognostic information...

We investigated the ability of folic acid to modulate the inflammatory responses of LPS activated BV-2 microglia cells and the signal transduction pathways involved. To this aim, the BV-2 cell line was exposed to LPS as a proinflammatory response inducer, in presence or absence of various concentrations of folic acid. The production of nitric oxide (NO) was determined by the Griess test. The levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and IL-10 were determined by ELISA. Inducible NO synthase (iNOS), nuclear transcription factor-kappa B (NF-κB) p65, MAPKs protein, and suppressors of cytokine signaling (SOCS)1 and SOCS3 were analyzed by western blotting...

OBJECTIVES: Folic acid (FA) is an important source for the prevention of many diseases. However, its use is limited because the very low solubility (<10 mg/l particularly in the gastric environment) responsible for the incomplete adsorption of the administered dose. This study proposes a technological strategy to overcome this problem enhancing FA dissolution rate by means of a formulation able to make completely bioavailable the whole administered dose. METHODS: Folic acid was intercalated in the layered double hydroxides (LDHs) MgAl-LDH and ZnAl-LDH...

The interfacial engineering of magnetic nanoparticles (MNPs) with specific functional groups or targeting ligands is important for their in vivo applications. We report here the preparation and characterization of bifunctional magnetic nanoparticles (BMNPs) which contain a carboxylic moiety for drug binding and an amine moiety for folate mediated drug targeting. BMNPs were prepared by introducing bioactive cysteine molecules onto the surface of undecenoic acid coated Fe3O4 magnetic nanoparticles (UMNPs) via a thiol-ene click reaction and then, folic acid was conjugated with these BMNPs through an EDC-NHS coupling reaction...

Folate is a vital component of a healthy diet, being essential for numerous bodily functions. Deficiency of folate is common, with studies suggesting prevalence of deficiencyas high as 85.5% as was shown in women between the ages of 16 and 49, living in the UK. Causes of folate deficiency range from diet and lifestyle, to pathological and pharmacological processes. Because of the well-known role of folate in prevention of neural tube defects, numerous countries have implemented strategies to increase folate intake, with programs such as mandatory grain fortification...

Copper sulfide nanoparticles (CuS NPs) have been reported as a single-compartment theranostic nanosystem to visualize and treat tumors simultaneously. However, few studies have investigated the in vivo tumor-targeted delivery of this class of nanoparticles. In this study, we introduced a tumor-specific targeting ligand, folic acid (FA), onto the surface of CuS NPs as a model system to demonstrate the feasibility of actively targeted CuS NPs for positron emission tomography (PET) imaging and PET image-guided photothermal therapy (PTT)...

The distinct and complementary biochemical mechanisms of folic acid analog methotrexate (MTX) and cytidine analog gemcitabine (GEM) make their synergistic combination effectively. Unfortunately, such a combination faces severe pharmacokinetic problems and several transportation barriers. To overcome these problems, a new strategy of amphiphilic small molecule prodrug (ASMP) is developed to improve their synergistic combination effect. The ASMP was prepared by the amidation of the hydrophilic GEM with the hydrophobic MTX at a fixed ratio...

It is notable that the adoption of GM glyphosate-tolerant crops increases glyphosate use but reduces non-glyphosate herbicide use; and adoption of GM insect-resistant crops significantly reduces insecticide use. While the health hazard of pesticide use has been well documented, little literature evaluates the health effects of different pesticides related to GM crops in an integrated framework. This study aims to associate the uses of different pesticides related to GM crops with the blood chemistry panel and peripheral nerve conduction of Chinese farmers...

Folic acid (FA) deficiency is not only associated with an increased risk of ischemic stroke, but also with increased oxidative DNA damage and brain injury after cerebral ischemia-reperfusion. However, the cellular and molecular mechanisms underlying FA deficiency-associated neuropathogenesis are not completely understood. In the present study, we tested the hypothesis that neuronal autophagy in focal cerebral ischemia rats may be involved in the mechanisms of FA deficiency-induced injury to neuronal cells. The results demonstrated that, accompanied by obvious neuron damage, the expression of the autophagic markers LC3 and Beclin-1, and the formation of 8-OHdG (a marker of oxidative stress to DNA) and autophagosomes were significantly increased in the brain cortex after ischemia-reperfusion...
