Biological activities of Bv8 analogues [PDF]
British Journal of Pharmacology, 2005 The small protein Bv8, secreted by the skin of the frog Bombina variegata, belongs to a novel family of secreted proteins whose orthologues have been identified in snakes (MIT) and in mammals (prokineticins (PKs)). A characteristic feature of this protein family is the same N‐terminal sequence, AVITGA, and the presence of 10 cysteines with identical ...

Biological Activity of Masked Endotoxin [PDF]
Scientific Reports, 2017 AbstractLow endotoxin recovery (LER) is a recently discovered phenomenon describing the inability of limulus amebocyte lysate (LAL)-based assays to detect lipopolysaccharide (LPS) because of a “masking effect” caused by chelators or detergents commonly used in buffer formulations for medical products and recombinant proteins.

Biological activities of cyclophellitol.
The Journal of Antibiotics, 1990 Cyclophellitol [1S,2R,3S,4R,5R,6R)-5-hydroxymethyl-7-oxabicyclo[4,1,0] heptane-2,3,4-triol) was tested against 9 glycosidases and found to be a specific inhibitor of almond beta-glucosidase. Cyclophellitol inhibited almond beta-glucosidase activity by 50% at 0.8 micrograms/ml and was a competitive inhibitor of almond beta-glucosidase as revealed by ...

On the mechanism of biological activation by tritium [PDF]
Journal of Environmental Radioactivity, 2016 The mechanism of biological activation by beta-emitting radionuclide tritium was studied. Luminous marine bacteria were used as a bioassay to monitor the biological effect of tritium with luminescence intensity as the physiological parameter tested. Two different types of tritium sources were used: HTO molecules distributed regularly in the surrounding

Active Materials: Biological Benchmarks and Transport Limitations [PDF]
arXiv, 2019 These lecture notes were prepared for the 2018 Summer School on `Active Matter and Non-equilibrium Statistical Physics' at l'\'{E}cole de Physique des Houches. They survey metabolic activity across a wide range of living organisms, and consider size limitations due to the transport of fuel, waste, and heat for active materials at biomimetic levels of ...

Biological activity of macromomycin.
The Journal of Antibiotics, 1979 Macromomycin (MCR) is a polypeptide antimuor antibiotic isolated from the culture broth of Streptomyces macromomyceticus. Antitumor activities of MCR were examined against three different tumor system, i.e., EHRLICH ascites carcinoma, L1210 leukemia and LEWIS lung carcinoma. Daily intraperitoneal treatment with MCR for 5 days showed a strong inhibition

Hyperpolarization of Amino Acid Derivatives in Water for Biological Applications [PDF]
arXiv, 2017 We report on the successful synthesis and hyperpolarization of N unprotected {\alpha} amino acid ethyl acrylate esters and extensively, on an alanine derivative hyperpolarized by PHIP (4.4$\pm$1% $^{13}$C-polarization), meeting required levels for in vivo detection.

Biological activities of bisdesmethoxycurcumin
Journal of Nature and Science of Medicine, 2020 Bisdesmethoxycurcumin (about 3%) is one of the three principal forms of Curcuminoids and reported to be more stable than the other two curcuminoids. Considering its pharmacological effects, the objective of this study was to assess antioxidant and anti-inflammatory potential of bisdesmethoxycurcumin.

Control of the Correlation of Spontaneous Neuron Activity in Biological and Noise-activated CMOS Artificial Neural Microcircuits [PDF]
arXiv, 2017 There are several indications that brain is organized not on a basis of individual unreliable neurons, but on a micro-circuital scale providing Lego blocks employed to create complex architectures. At such an intermediate scale, the firing activity in the microcircuits is governed by collective effects emerging by the background noise soliciting ...
