A smart mesoporous silica nanocarrier with intracellular controlled release is fabricated, with folic acid as dual-functional targeting and capping agent. The folate not only improves the efficiency of the nanocarrier internalized by the cancer cells, but also blocks the pores of the mesoporous silica to eliminate premature leakage of the drug. With disulfide bonds as linkers to attach the dual...

New inhibitors are urgently needed to overcome the burgeoning problem of drug resistance in the treatment of Plasmodium falciparum infection. Targeting the folate pathway has proved to be a powerful strategy for drug development against rapidly multiplying systems such as cancer cells and microorganisms. Antifolates have long been used for malaria treatment but, despite their success, much less...

The complimentary ability of different noninvasive imaging technologies with therapeutic modalities can be used in tandem providing high-resolution and highly sensitive imaging of events at the molecular and cellular level providing a means for image-guided therapy. There is increasing interest in using porphyrin-based photosensitizers as theranostics to take advantages of their near-infrared f...

A folate conjugated ternary copolymer, FA-PEG-PEI-PCL, of poly(ethylene glycol) (PEG), poly(ethylene imine) (PEI), and poly(ɛ-caprolactone) (PCL) was synthesized. The copolymer self-assembled into cationic micelles capable of co-delivering siRNA and the anticancer drug doxorubicin (DOX). This dual functional nanocarrier demonstrated low cytotoxicity and high performance in drug/siRNA delivery. ...

  Background: Inadequate folate intake could be associated with increased breast cancer risk. The aim of the present study was to assess the folate intake by designed Food Frequency Questionnaire (FFQ) using plasma folate concentration.   Methods: This analytic cross-sectional study was conducted to evaluate the validity of the semi-quantitative FFQ (136 items) in 152 women with confirmed breas...

background: coronary artery disease (cad) is emerging as a major public health concern in most developing countries. during the past 10 years, the vast majority of over 100 case-control retrospective studies have shown that elevated plasma homocysteine level is a strong independent risk factor for coronary artery disease. methylenetetrahydrofolate reductase (mthfr) is a key enzyme in folate and...

OBJECTIVE To prepare folic acid-chitosan conjugated nanoparticles (FA-CS NPs) and evaluate their targeting specificity on tumor cells. METHODS Chitosan (CS) NPs were prepared by ionic cross linking method, and folic acid (FA) was conjugated with CS NPs by electrostatic interaction. The properties of NPs were investigated, and doxorubicin hydrochloride (Dox) as a model drug was encapsulated fo...

Tetrahydropterin-dependent aromatic amino acid hydroxylases (AAHs) are known from animals and microbes but not plants. A survey of genomes and ESTs revealed AAH-like sequences in gymnosperms, mosses, and algae. Analysis of full-length AAH cDNAs from Pinus taeda, Physcomitrella patens, and Chlamydomonas reinhardtii indicated that the encoded proteins form a distinct clade within the AAH family. ...
