Abstract:
A bottom-up approach identifying equivalent effects of high-pressure processing (HPP—600 MPa, 20 °C, 10 min), thermal treatment (TT—70 °C, 15 min) and high pressure-mild thermal processing (HPMT—600 MPa, 50 °C, 10 min) on quality and stability of peach–strawberry puree was applied during refrigerated storage. TT and HPP ensured 3-log aerobic bacteria inactivation at first, while HPMT reduction was below the detection limit. After 21 days all samples had equivalent microbiological stability. A 2.6-fold increase in the residual activity of PPO and POD was found in the HPP sample compared to TT a

However, studies on 10 keV radiation effects on the SiC SBDs were rarely reported. In this paper, the performance degradation of the SiC SBDs irradiated by 10 keV electrons at different fluences was investigated. After the irradiation, the forward current of the SiC

Alcohol dose dumping can occur due to the solubility of the pharmaceutical excipients, the solubility of the drug, and the formulation’s drug release mechanism. Cellulosics are the most commonly used polymers in pharmaceutical controlled release technologies. The ethanol vulnerability of tablets made with HPMC K250, HPMC K750 and HPMC K1500 were investigated with the low soluble drug quetiapine fumarate. Quetiapine fumarate is an antipsychotic drug and it is suitable drug candidate for FDDS due to its solubility in low pH. HPMC K250, HPMC K750 and HPMC K1500 were used as a polymer matrix to co

In order to achieve the controlled release of curcumin, HPMC (hydroxypropyl methyl cellulose) was spray dried with curcumin and lactose. The spray-dried materials were pressed into tablets with a diameter of 8 mm, and their release characteristics in vitro were measured. In vitro experiments showed that the release of curcumin from the HPMC mixture was significantly slower due to the sustained-release property of HPMC as a typical excipient. The release profile of curcumin from the HPMC mixture was relatively stable for a controlled release. SEM images show that the HPMC co-spray-dried powders

Over several years, significant progress has been achieved in reducing the dislocation density of the typical insulating HPHT substrate from the order of 104–105 cm-2 to 102 cm-2.

Decapping of eukaryotic messenger RNAs (mRNAs) occurs after they have undergone deadenylation, but how these processes are coordinated is poorly understood. In this study, we report that Drosophila melanogaster HPat (homologue of Pat1), a conserved decapping activator, interacts with additional decapping factors (e.g., Me31B, the LSm1–7 complex, and the decapping enzyme DCP2) and with components of the CCR4–NOT deadenylase complex. Accordingly, HPat triggers deadenylation and decapping when artificially tethered to an mRNA reporter. These activities reside, unexpectedly, in a proline-rich regi

Abstract:
Hydroxypropyl methylcellulose (HPMC) is a kind of biopolymer that is biodegradable, environmentally friendly and possesses exceptional mechanical and tribological properties. Therefore, it could be used as a suitable alternative to plastic. However, HPMC deforms easily when subjected to loads, causing higher real contact area and adhesive force between HPMC and grinding counter. Therefore, HPMC films are easily damaged because of adhesive wear, which negatively affects wear resistance. Hence, nanoparticles (NPs) of Al, Cu, Al2O3 and CuO have been used as fillers to increase the wear resistance
