Fluorine teams up with water to restore inhibitor activity to mutant BPTI.

Chemical science

Ye S, Loll B, Berger AA, Mülow U, Alings C, Wahl MC, Koksch B.
PMID: 29449928
Chem Sci. 2015 Sep 01;6(9):5246-5254. doi: 10.1039/c4sc03227f. Epub 2015 Jun 12.

Introducing fluorine into molecules has a wide range of effects on their physicochemical properties, often desirable but in most cases unpredictable. The fluorine atom imparts the C-F bond with low polarizability and high polarity, and significantly affects the behavior...

Protease activation mutants elicit protective immunity against highly pathogenic avian influenza viruses of subtype H7 in chickens and mice.

Emerging microbes & infections

Wagner R, Gabriel G, Schlesner M, Alex N, Herwig A, Werner O, Klenk HD.
PMID: 26038453
Emerg Microbes Infect. 2013 Feb;2(2):e7. doi: 10.1038/emi2013.7. Epub 2013 Feb 27.

Protease activation mutants of the highly pathogenic avian influenza virus A/FPV/Rostock/34 (H7N1) have been generated that are fully dependent on the presence of trypsin for growth in cell culture. Unlike wild-type virus, the mutants do not induce systemic infection...

Induced resistance in soybean toHelicoverpa zea: Role of plant protein quality.

Journal of chemical ecology

Bi JL, Felton GW, Mueller AJ.
PMID: 24241708
J Chem Ecol. 1994 Jan;20(1):183-98. doi: 10.1007/BF02066000.

Resistance in soybean toHelicoverpa zea is comprised of both constitutive and inducible factors. In this study, we investigated the induction of resistance byH. zea in both greenhouse and field studies. In a greenhouse experiment, fourth-instarH. zea growth rates were...

Deterministic switching of ferromagnetism at room temperature using an electric field.

Nature

Heron JT, Bosse JL, He Q, Gao Y, Trassin M, Ye L, Clarkson JD, Wang C, Liu J, Salahuddin S, Ralph DC, Schlom DG, Iñiguez J, Huey BD, Ramesh R.
PMID: 25519134
Nature. 2014 Dec 18;516(7531):370-3. doi: 10.1038/nature14004.

The technological appeal of multiferroics is the ability to control magnetism with electric field. For devices to be useful, such control must be achieved at room temperature. The only single-phase multiferroic material exhibiting unambiguous magnetoelectric coupling at room temperature...

Fish peptone development using enzymatic hydrolysis of silver carp by-products as a nitrogen source in Staphylococcus aureus media.

Food science & nutrition

Fallah M, Bahram S, Javadian SR.
PMID: 25838893
Food Sci Nutr. 2015 Mar;3(2):153-7. doi: 10.1002/fsn3.198. Epub 2015 Jan 19.

Fish peptone was produced using enzymatic hydrolysis of silver carp filleting by-products by alcalase and trypsin. Also, the efficiency of the hydrolysates as a nitrogen source in Staphylococcus aureus medium was compared with commercial TSB. The results indicated that...

Intercellular adhesion : I. A quantitative assay for measuring the rate of adhesion.

The Journal of membrane biology

Orr CW, Roseman S.
PMID: 24174045
J Membr Biol. 1969 Dec;1(1):109-24. doi: 10.1007/BF01869777.

A quantitative procedure for determining the early kinetics of cell aggregation (adhesion) is described. The cells used for this study were obtained by dissociation of 8-day-old embryonic chicken neural retina with crude trypsin. The method is based on determining...

Protein-nitrogen flux and protein growth efficiency of individual Atlantic salmon (Salmo salar L.).

Fish physiology and biochemistry

Carter CG, Houlihan DF, Buchanan B, Mitchell AI.
PMID: 24202872
Fish Physiol Biochem. 1993 Dec;12(4):305-15. doi: 10.1007/BF00004415.

Protein-nitrogen flux (the proportions of consumed and absorbed protein-nitrogen partitioned into protein synthesis and growth) was examined in Atlantic salmon, Salmo salar L. Salmon were held in groups and fed high or low rations or starved. Individual food consumption...

Stem Cell Niche is Partially Lost during Follicular Plucking: A Preliminary Pilot Study.

International journal of trichology

Kumar A, Gupta S, Mohanty S, Bhargava B, Airan B.

Int J Trichology. 2013 Apr;5(2):97-100. doi: 10.4103/0974-7753.122973.

BACKGROUND: Clinical hair transplant studies have revealed that follicular unit extraction (FUE) is superior in terms of stable hair growth in comparison to follicular plucking (FP). Various reasons have been cited for this clinical outcome. FUE and FP are...

Enzymatic peptide synthesis by new supported biocatalysts.

Amino acids

Rolland-Fulcrand V, May N, Viallefont P, Lazaro R.
PMID: 24189739
Amino Acids. 1994 Oct;6(3):311-4. doi: 10.1007/BF00813751.

It is well known that proteases can be successfully used for peptide synthesis in aqueous medium or in water-containing organic solvents. Copolymerized of acrylated derivatives ofα-chymotrypsin and polyethylene glycol (PEG) have been prepared and used as biocatalysts for the...

Rhizoma Pinelliae trypsin inhibitor separation, purification and inhibitory activity on the proliferation of BGC-823 gastric adenocarcinoma cells.

Experimental and therapeutic medicine
