Physical stress (i.e., bruising) during harvesting, handling, and transportation triggers enzymatic discoloration of mushrooms, a common and detrimental phenomenon largely mediated by polyphenol oxidase (PPO) enzymes. Hyperspectral imaging (HSI) is a nondestructive technique that combines imaging and spectroscopy to obtain information from a sample. The objective of this study was to assess the...

KOCAQALISKAN I., DEMIR Y. & KABAR, K. 1995. A study on polyphenol oxidase activity during seed germination. Phyton (Horn, Austria) 35 (1): 37-43. English with German summary. In this work, polphenol oxidase (PPO) activities, when used four different substrates (dopa,catechol,caffeic acid, tyrosine) oxidizing activities, during seed germination of six different plants were studied in the embryos...

Pre-defined, researcher-selected outcomes are routinely used as the clinical end-point in randomized controlled trials (RCTs); however, individualized approaches may be an effective way to assess outcome in mental health research. The present study describes the development and evaluation of the Individualized Outcome Measure (IOM), which is a patient-specific outcome measure to be used for RCT...

Abstract Biomolecule adsorption is the first stage of biofouling. The aim of this work was to reduce the adsorption of proteins on stainless steel (SS) and titanium surfaces by modifying them with a poly(ethylene oxide) (PEO)-poly(propylene oxide) (PPO)-PEO triblock copolymer. Anchoring of the central PPO block of the copolymer is known to be favoured by hydrophobic interaction with the substra...

Residual enzymatic activity in certain foods, particularly of polyphenoloxidase (PPO), is responsible for the majority of anthocyanin degradation in food systems, causing also parallel losses of other relevant nutrients. The present work explored the feasibility of modifying phenolic profiles of thyme extracts, by use of chromatographic resins, to obtain phenolic extracts capable of enhancing a...

Successful clinical and radiographic outcomes have been reported in patients with unilateral developmental dysplasia of the hip (DDH) following Pemberton pericapsular osteotomy (PPO). However, residual gait deviations are seen in both the affected and unaffected limbs. To date it is not known whether these deviations result in abnormal plantar pressure in such patients. This study investigated ...

PURPOSE The ability to develop high levels of muscle power is considered an essential component of success in many sporting activities; however, the optimal load for the development of peak power during training remains controversial. The aim of the present study was to determine the optimal load required to observe peak power output (PPO) during the hang power clean in professional rugby playe...

Although a vast amount of research has been dedicated to investigate the Hofmeister effect on the stability of polymer solutions, a clear understanding of the role of polymer properties in this phenomenon is still missing. Here, the Hofmeister effect of NaCl (destabilizing) and NaSCN (stabilizing) salts on aqueous solutions of poly(propylene oxide) (PPO) is studied. Four different molecular wei...

-The paper develops innovative methodology for the robust and stable design of digital infinite impulse response (IIR) filters using predator-prey optimization (PPO) method. Predator-prey optimization is undertaken as a global search technique and exploratory search is exploited as a local search technique. Being a stochastic optimization procedure, PPO technique, avoids local stagnation as pre...

A series of polyether-based diblock copolymers were synthesized by sequential organocatalytic ring-opening polymerization (ROP) either hexene oxide (HO) or octene (OO) as the first monomer with propylene (PO) second monomer. In addition, one triblock terpolymer OO, PO, and styrene (SO) was following same method. The ROP catalyzed triethyl borane (TEB)/(phosphazene base t-BuP2) eicosanol initiat...
