Tapping the biotechnological potential of insect microbial symbionts: new insecticidal porphyrins
(BioMed Central, 2017)
Abstract
Background
The demand for sustainable agricultural practices and the limited progress toward newer and safer chemicals for use in pest control maintain the impetus ...
Hybrid bacterial cellulose-pectin films for delivery of bioactive molecules
(Royal Society of Chemistry, 2018-03)
Novel biopolymeric films based on bacterial cellulose (BC) modified with high methoxylated pectin (HMP) were developed for drug delivery. The ability of the films to incorporate an antibiotic, levofloxacin (Levo), was ...
Ozone: a natural bioactive molecule with antioxidant property as potential new strategy in aging and in neurodegenerative disorders
Systems medicine is founded on a mechanism-based approach and identifies in this way
specific therapeutic targets. This approach has been applied for the transcription factor nuclear
factor (erythroid-derived 2)–like 2 ...
Metformin and soybean-derived bioactive molecules attenuate the expansion of stem cell-like epithelial subpopulation and confer apoptotic sensitivity in human colon cancer cells
(Genes & Nutrition, 2015)
Colorectal cancer (CRC) is a disease whose genesis may include metabolic dysregulation. Cancer stem cells are attractive targets for therapeutic interventions since their aberrant expansion may underlie tumor initiation, ...
Effect of desialylated human chorionic gonadotropin (hCG) on the bioactivity of rat Leydig cells
(1998)
Human chorionic gonadotropin is a glycoprotein hormone that, like LH, stimulates steroidogenesis in gonadal cells. Using a desialylation process, 95 per cent of the sialic acid residues from an intact standard hCG molecule ...
Formation, antimicrobial activity, and controlled release from cotton fibers with deposited functional polymers
(Wiley, 2016)
Chitosan and alginate are biopolymers with interesting bioactivity that can be transferred to cotton fibers for medical and health care applications. These polymers in solution can be attached onto cotton fibers by a ...
Purificação e caracterização bioquímica de substâncias bioativas produzidas por endofítico isolado de Prunus spp.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotec, 2009-03-13)
Bioprospective studies of endophytic microorganisms for biotechnological applications are essentials to discovery new substances, which can be used in different areas. Endophytes represent an excellent source of bioactive ...
UVA I-protection effectiveness of bioactive compound and organic UV filters: an in vitro assessment
(Sociedade Brasileira de Química, 2009)
This research work aimed at determining the UVA effectiveness (UVA I/UV ratio), by diffuse transmittance analysis, of sunscreens developed with a bioactive substance, the rutin, associating or not with organic UVB-UVA ...
