Bioactivities of bulk fish protein hydrolysates (FPH) from defatted salmon backbones obtained with eight different commercial enzymes and their combinations were tested. All FPH showed antioxidative activity in vitro. DPPH scavenging activity increased, while iron chelating ability decreased with increasing time of hydrolysis. All FPH showed ACE inhibiting effect which depended on type of enzym...

A tripyrrole peptide-Hoechst conjugate (FPH-1) has been designed which recognizes nine dA/dT base pair A/T rich dsDNA sequences at subnanomolar concentrations and complexes its targets at near diffusion controlled rates to form a fluorescent product. Spectrofluorometric titrations show the stoichiometry of the complex to be (FPH-1)(2):dsDNA. Spectrofluorometric titrations were also employed to ...

The functional, nutritional, and antioxidative properties of hydrolyzed herring and herring byproducts (head and gonad) were evaluated. All freeze-dried herring fish protein hydrolysate (FPH) powders were light yellow and contained 77% to 87% protein. The degree of hydrolysis was 18.3%, 13%, 13%, and 10.1%, respectively, for head, whole fish, body, and gonad after 75 min digestion. All FPH powd...

Two fish protein hydrolysates (FPH) were incorporated into four diets prepared for start-feeding sea bass larvae, at two different levels (10% and 19% of total ingredients): a commercial FPH, CPSP, in which the molecular mass of the main fraction of soluble peptides (51%) was between 500-2500 Da, and an experimental FPH obtained by acidic silage of sardine offal, SH, with a main portion of solu...

Thermoase-digested flaxseed protein hydrolysate (FPH) samples and ultrafiltration membrane-separated peptide fractions were initially evaluated for in vitro inhibition of angiotensin I-converting enzyme (ACE) and renin activities. The two most active FPH samples and their corresponding peptide fractions were subsequently tested for in vivo antihypertensive activity in spontaneously hypertensive...

The NOAA frost point hygrometer (FPH) is a balloon-borne instrument flown monthly at three sites to measure water vapor profiles up to 28 km. The FPH record from Boulder, Colorado, is the longest continuous stratospheric water vapor record. The instrument has an uncertainty in the stratosphere that is < 6 % and up to 12 % in the troposphere. A digital microcontroller version of the instrument i...

FPH-1 is a new class A carbapenemase from Francisella philomiragia. It produces high-level resistance to penicillins and the narrow-spectrum cephalosporin cephalothin and hydrolyzes these β-lactam antibiotics with catalytic efficiencies of 10(6) to 10(7) M(-1) s(-1). When expressed in Escherichia coli, the enzyme confers resistance to clavulanic acid, tazobactam, and sulbactam and has K(i) valu...

A series of 10 novel analogues of fluphenazine (FPh) were synthesized. Influence of the synthesized analogues of FPh on frequency of apoptosis and necrosis in cultures of human lymphocytes genotoxically damaged in vitro with benzo[a]pyrene (B[a]P; 7,5 microM, 48 h) was compared with the effect of FPh. Activity of the tested compounds was expressed by ED50 (pro-apoptotic activity) and TD50 (pro-...

BACKGROUND Fish protein hydrolysates (FPHs) have been reported as a suitable source of proteins for human nutrition because of their balanced amino acid composition and positive effect on gastrointestinal absorption. OBJECTIVE Here, we investigated the effect of a FPH, Slimpro(®), obtained from blue whiting (Micromesistius poutassou) muscle by enzymatic hydrolysis, on body composition and on ...

Fish protein hydrolysate (FPH) is the enzymatic hydrolysis of into smaller peptide and free amino acids, which has recently captured considerable attention as a supplementary ingredient in aqua-feed industry sector. The present research aimed to observe physiological, biochemical, bacteriological study FPH-treated diets its effects on growth, hematology, plasma biochemistry, liver gut histopath...
