The binding behavior of a competitive inhibitor, N-phenylbenzhydroxamic acid (BHA) against horseradish peroxidase (HRP) was studied in order to understand and predict the interaction mechanism of hydrogen donors with the enzyme. The dissociation constants of the complexes of HRP-BHA, HRP-donor and HRP-BHA-azide were estimated at specified conditions by difference spectroscopy. The binding s...

Hierarchical A∗ (HA∗) uses of a hierarchy of coarse grammars to speed up parsing without sacrificing optimality. HA∗ prioritizes search in refined grammars using Viterbi outside costs computed in coarser grammars. We present Bridge Hierarchical A∗ (BHA∗), a modified Hierarchial A∗ algorithm which computes a novel outside cost called a bridge outside cost. These bridge costs mix finer outside sc...

Composites of calcinated bovine bone derived hydroxyapatite (BHA) doped 1 and 2 wt% MgF2 were prepared by a sintering process. Microstructure crystallographic analyses along with measurements density, compression strength, microhardness carried out in the produced samples. The experimental results indicated beneficial effect matrix BHA reflected significant increase strength up to 143 MPa 313 H...

In a structure analysis of the compounds of the genus Piper (Family Piperaceae), we identified five phenolic amides from Piper nigrum, seven compounds from P. retrofractum, and two compounds from P. baccatum. All the phenolic amides possess significant antioxidant activities that are more effective than the naturally occurring antioxidant, alpha-tocopherol. One amide, feruperine, has antioxidan...

Development of polypropylene (PP) films incorporating antioxidant-antimicrobial agents can inhibit microbial growth and reduce undesirable deteriorating reactions preserve the quality food. This study was aimed to use a combination sorbic acid (SA), butylated hydroxyanisole (BHA), hydroxytoluene (BHT) provide synergistic effect at their reduced concentrations. A Combination additives more effec...

The Panel on Food Additives and Nutrient Sources added to Food (ANS) delivers a scientific opinion re-evaluating the safety of butylated hydroxyanisole (BHA) (E 320). BHA is a synthetic antioxidant authorised as a food additive in the EU that was previously evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) several times, the latest in 1989 and the EU Scientific Committee...

Forced vital capacity (FVC) and maximal exercise response were measured in two populations of Peruvian males (age, 18-35 years) at 4,338 m who differed by the environment in which they were born and raised, i.e., high altitude (Cerro de Pasco, Peru, BHA, n = 39) and sea level (Lima, Peru, BSL, n = 32). BSL subjects were transported from sea level to 4,338 m, and were evaluated within 24 hr of e...

Patients with bilateral hippocampal atrophy (BHA) in a subgroup suffering from mesial temporal lobe epilepsy represent a therapeutic challenge. We achieved successful surgical treatment in a case with BHA and false lateralized ictal onset on video-scalp electroencephalogram (EEG). A 27-year-old male patient with seizures since the age of 15 years showed current seizures consisting of an epigast...

This study was designed to evaluate the effects of dietary treatment, packaging, and irradiation singly or in combination on the oxidative stability of broiler chicken thigh meat. A total of 120 four-week-old chickens were divided into 12 pens (10 birds/pen), and 4 pens of broilers were randomly assigned to a control oxidized diet (5% oxidized oil) or an antioxidant-added diet [500 IU of vitami...

In this paper, −10 μm rutile and −30 garnet particles were selected as samples. The effects of different reagents on the flotation single minerals studied, mechanism was analyzed by contact angle, zeta potential, Fourier transform infrared (FTIR) measurements. results show that an optimal recovery is obtained with benzohydroxamic acid (BHA) collector for sodium silicofluoride (SSF) inhibitor ga...
