Heat treatment

In this Masters thesis computational modelling techniques were employed to investigate iron-free apo-Lactoferrin (apo-Lf) structural conformation changes in the presence of variant temperature and pH. These conditions represent the environment most milk protein goes through in food processing and the production of food products.

In this present work, A356 aluminum alloy is heat treated with the addition of copper, rare earth and strontium were investigated. T6 treatment is preferred in this work (solution at 535°C for 4h + aging at 150°C for 15h) when compared to other heat treatment processes (i.e short heat treatment processes).

This study focuses on 316L stainless steel fabricated by selective laser melting (SLM) in the context of nuclear application, and compares with a cold-rolled solution annealed 316L sample. The effect of heat treatment (HT) and hot isostatic pressing (HIP) on the microstructure and mechanical properties is discussed.

An analytical and numerical solution is developed for a transient heat conduction equation in which a plane slab is heated by a bimodal distribution beam over the upper surface. In laser heat treatment of steel few methods are used to produce a wider and nearly uniform average irradiance profile.

Bovineb-lactoglobulin was hydrolyzed with trypsin or chymotrypsin in the course of heat treatment at 55, 60 and 65°C at neutral pH. At these temperaturesb-lactoglobulin undergoes signi®cant but reversible structural changes. In the conditions used in the present study,b-lactoglobulinwas virtually insensitive to proteolysis by either enzyme at room temperature, but underwent extensive proteolysis when either proteasewas present during the heat treatment.

The structural features of the hyperthermophilic endo-b-1,3-glucanase from Pyrococcus furiosuswere studied using circular dichroism, steady-state and time-resolved fluorescence spectroscopy and anisotropy. Upon heat and chemical treatment the folded and denatured states of the protein were characterized by distinguishable spectral profiles that identified a number of conformational states.

The induction of the heat shock response as well as its termination is auto-regulated by heat shock protein activities. In this study we have investi-gated whether Hsp90 functional protein levels influence the characteristics and duration of the heat shock response. Treatment of cells with several benzoquinone ansamycin inhibitors of Hsp90 (geldanamycin, herbimycin A) activated a heat shock response in the absence of heat shock, as reported previously.

Proteins tend to form inactive aggregates at high tempera-tures. We show that polyamines, which have a relatively simple structure as oligoamids, effectively prevent thermal inactivation and aggregation of hen egg lysozyme. In the presence of additives, including arginine and guanidine (100 mM), more than 30% of 0.2 mgÆmL )1 lysozyme in sodium phosphate buffer (pH 6.5) formed insoluble aggre-gates by heat treatment (98
C for 30 min). 1

We recently reported that the transient expression of polyglutamine tracts of various size in exon 1 of the huntingtin polypeptide (httEx1) generated abnormally high levels of intracellular reactive oxygen species that directly contributed to cell death. Here, we compared the protection generated by heat shock proteins to that provided by the antioxidant agentN-acetyl-l-cysteine.

In recent years, heat treatment has been used to prevent the development of chilling injury in fruits and vegetables. The acquired tolerance to chilling seen in treated fruit is related to the accumulation of heat shock proteins (HSPs).

Hydrogen peroxide (H2O2) is a well known oxidative stress inducer causing apoptosis of many cells. Previously, we have shown that heat shock pre-treatment blocked the release of the second mitochondria-derived activator of caspase (Smac) to the cytosol and inhibited apoptosis of C2C12 myo-blast cells in response to H2O2.

The tyrosine phenol-lyase fromSymbiobacterium toebiiwas engineered to improve both its stability and catalytic activity by the application of ran-dom mutagenesis and subsequent reassembly of the acquired mutations. Activity screening of the random library produced four mutants with a two-fold improved activity, whereas parallel screening after heat treatment at 65C identified three mutants with half-inactivation temperatures improved by up to 5.6 C.
