1. Spider venom peptides as potential drug candidates due to their anticancer and antinociceptive activities
Abstract Spider venoms are known to contain proteins and polypeptides that perform various functions including antimicrobial, neurotoxic, analgesic, cytotoxic, necrotic, and hemagglutinic activities. Currently, several classes of natural molecules from spider venoms are potential sources of chemotherapeutics against tumor cells. Some of the spider peptide to

3. Pharmacological characterization of cnidarian extracts from the Caribbean Sea: evaluation of anti-snake venom and antitumor properties
Abstract Background: Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities. This study aimed to evaluate toxicological activities and potential as antitumor and antiophidic agents contained in total extracts from fi

4. Scedosporium apiospermum, Scedosporium aurantiacum, Scedosporium minutisporum and Lomentospora prolificans: a comparative study of surface molecules produced by conidial and germinated conidial cells
BACKGROUND Scedosporium/Lomentospora species are opportunistic mould pathogens, presenting notable antifungal resistance. OBJECTIVES/METHODS We analysed the conidia and germinated conidia of S. apiospermum (Sap), S. aurantiacum (Sau), S. minutisporum (Smi) and L. prolificans (Lpr) by scanning electron microscopy and exposition of surface molecules by fluor

5. Tomato second cycle hybrids as a source of genetic variability for fruit quality traits
Abstract The objective of this study was to investigate the phenotypic and molecular variability in a F2 generation derived from a SCH (Second Cycle Hybrid) in order to detect QTLs for some fruit traits of tomato. Genome coverage at different levels was achieved by three types of molecular markers (polypeptides, sequence-related amplified polymorphism-SRAP a

6. Crucial Residues Modulating Interface of hBcl-B - hBaxBH3 Heterodimer as Probed by Computational Methods
ABSTRACT Cancerous cells develop resistance to cell death by over expression of anti-apoptotic proteins, which are specific to interact with pro-apoptotic and BH3-only proteins of Bcl-2 family. Delineating crucial residues mediating the heterodimer complexes (anti-apoptotic proteins - pro-apoptotic/BH3-only proteins) is indispensable to develop specific anta

7. Detection of Specific Polypeptide(s) Synthesized during the Sequential Stages of Differentiation in Dioscorea species
ABSTRACTThe present investigation was aimed to detect the specific polypeptide(s) appeared during the sequential stages of differentiation. Among different explants, only nodal explants showed good results for callusing. Depending on the fresh and dry weight, best callus growth was observed on MS medium supplemented with NAA (2.5 mg/L) inDioscorea alata and

8. Role of Light and Dark Cycle and Different Temperatures in the Regulation of Growth and Protein Expression in Oscillatoria agardhii Strain
The cyanobacterium Oscillatoria agardhii was isolated from the fresh water Mawatha lake, Jaipur and was grown in Zarrouk's medium at 25 ± 2°C, illuminated with white fluorescent light at the intensity of 2 500 lux with 12:12 h light and dark photoperiod. The effects of photoperiod and temperature on the growth and protein expression by Oscillatoria agardhi

9. Effects of sequential enzymatic hydrolysis on structural, bioactive and functional properties of Phaseolus lunatus protein isolate
Significant initiatives exist within the global food market to search for new, alternative protein sources with better technological, functional, and nutritional properties. Lima bean (Phaseolus lunatus L.) protein isolate was hydrolyzed using a sequential pepsin-pancreatin enzymatic system. Hydrolysis was performed to produce limited (LH) and extensive hydr

10. Molecular cloning and mRNA expression of the peptidoglycan recognition protein gene HcPGRP1 and its isoform HcPGRP1a from the freshwater mussel Hyriopsis cumingi
Peptidoglycan recognition proteins (PGRPs) are innate immune molecules that have been structurally conserved throughout evolution in invertebrates and vertebrates. In this study, peptidoglycan recognition protein HcPGRP1 and its isoform HcPGRP1a were identified in the freshwater mussel Hyriopsis cumingii. The full-length cDNAs of HcPGRP1 (973 bp) and HcPGRP1

11. Produção e eficácia de anticorpos gerados contra glicolipídios de Paracoccidioides brasiliensis / Production and efficacy of antibodies generated against glycolipids of P. brasiliensis
Paracoccidioidomycosis (PCM) is a systemic fungal infection most prevalent in Latin America, whose etiologic agent, Paracoccidioides brasiliensis, is a yeast with a complex cell wall structure consisting of proteins, glycoproteins, polysaccharides, lipids, and melanin polypeptides that gather physical, chemical and biological conditions to serve as antigens.

12. Efeitos de uma desintegrina RGD recombinante de Rhinocerophis alternatus (Bothrops alternatus) na migração de células normais e tumorais
Cell migration, invasion of the surrounding tissues, blood vessels and proliferation are cellular processes involved in metastases. These events are mediated by integrins, adhesion receptors present on cell surfaces and responsible for the extracellular matrix and cells binding. Disintegrins, snake venoms polypeptides, are known to inhibit integrins action,
