Chronic inflammation, which is caused by recurrent infections, is one of the factors contributing to the pathogenesis of cholesteatoma. If reimplantation of autologous ossicles after a surgical intervention is intended, inactivation of planktonic bacteria and biofilms is desirable. High hydrostatic pressure treatment is a procedure, which has been used to inactivate cholesteatoma cells on ossicles. Here we discuss the potential inactivating effect of high hydrostatic pressure on microbial pathogens including biofilms. Recent experimental data suggest an incomplete inactivation at a pressure level, which is tolerable for the bone substance of ossicles and results at least in a considerable reduction of pathogen load. Further studies are necessary to access how far this quantitative reduction of pathogens is sufficient to prevent ongoing chronic infections, for example, due to forming of biofilms.

We carried out limited enzymatic hydrolysis with trypsin on rice bran protein (RBP) pretreated by high hydrostatic pressure (HHP) in this study. The effects of the degree of hydrolysis (DH) on the structural and emulsifying properties were investigated. The results indicated that the molecular structure of RBP changed after limited enzymatic hydrolysis.

Shiitake mushroom is popularly consumed thanks to its umami taste and good flavor, but its stipe is often discarded due to the rough texture and poor chewiness. In the study, high-pressure homogenization (HPH) was applied to modify the physiochemical properties of shiitake mushroom nanocellulose (SMNC), and the SMNCs were used to constructing gel-like emulsions (EGs). Atomic force microscope and cryo-scanning electron microscope observations showed that SMNCs had shorter length after HPH treatment.

Magnesium and calcium carbonate minerals are significant reservoirs of Earth's carbon and understanding their behavior under different conditions is crucial for elucidating the mechanisms of deep carbon storage. Huntite, MgCa(CO), is one of the two stable calcium magnesium carbonate phases, together with dolomite. The distinctive cation coordination environment of Ca atoms compared to calcite-type and dolomite structures makes huntite a comparatively less dense phase.

Proteins found within the fungal cell wall usually contain both - and -oligosaccharides. -glycosylation is the process where these oligosaccharides (hereinafter: glycans) are attached to asparagine residues, while in -glycosylation the glycans are covalently bound to serine or threonine residues. The family is grouped into , , and subfamilies.

Trunk-like robots have attracted a lot of attention in the community of researchers interested in the general field of bio-inspired soft robotics, because trunk-like soft arms may offer high dexterity and adaptability very similar to elephants and potentially quite superior to traditional articulated manipulators. In view of the practical applications, the integration of a soft hydrostatic segment with a hard-articulated segment, i.e.
