Abstract:

Abstract Modelling of an axial-type piezoelectric generator (PEG) is considered. PEG is an integral part of the system for converting mechanical vibration energy from the environment into electrical energy. The energy generator has an axial type of the configuration of elements, aimed on using bending and compressive loads simultaneously on piezoelectric elements. The base of the generator is made as an active pinching. A feature of PEG is that the generator has two types of piezoelectric elements: (1) elements located on the substrate in the form of a bimorph and (2) piezoelectric elements of

Abstract:

Doxorubicin (adriamycin; ADR) which is one of the most clinically used antitumor agent, has undesirable side-effects. To reduce these side-effects, a macromolecular prodrug of ADR exhibiting high antitumor activity, the conjugate of PEG end-capped with ADR was developed. Tb effect intracellular release of ADR from the conjugate, ester, amide and Schiffs base bonds were employed as modes of bonding ADR to PEG. The MeO-PEG/Schiffs base/ADR conjugate readily released ADR under the lysosomal acidic conditions in vitro and very slowly ADR under physiological conditions. Moreover, the MeO-PEG/Schiff

Osmolytes and macromolecular crowders have the potential to influence the stability of secondary structure motifs and alter preferences for conserved nucleic acid sequences in vivo. To further understand the cellular function of RNA we observed the effects of a model osmolyte, polyethylene glycol (PEG) 200, and a model macromolecular crowding agent, PEG 8000, on the GAAA tetraloop motif. GAAA tetraloops are conserved, stable tetraloops, and are critical participants in RNA tertiary structure. They also have a thermodynamic preference for a CG closing base pair.

Here, we report a more convenient approach for PEG synthesis featuring the use of a base-labile protecting group such as the phenethyl group.

This concept holds promise as a smart and versatile drug delivery system for the achievement of targeted, more efficient cancer chemotherapy. Due to A–U base pairing between BU-PEG and A-R6G, BU-PEG has high tendency to interact with A-R6G, which leads to the

One microtubule-laden dendrite completely fills the distal portion of the dendritic sheath and ends within the peg. It is joined by a lamellate and a scolopidium-like dendrite that end near and below the base of the peg, respectively. The ciliary sinus is large and the membrane of

Abstract In this study, the impact of putrescine, a polyamine, on the germination, seedling growth, and mitotic index of rye seeds (cv. Aslım-95) was investigated under osmotic drought conditions induced by polyethylene glycol (PEG-6000) application. The experiment involved six different PEG doses (-2, -4, -6, -8, and -10 bars) in combination with putrescine doses of 0.001, 0.01, and 0.1 mM. The concentration of -2 bars of polyethylene glycol, representing osmotic drought, positively influenced some of the studied characteristics. However, the stimulative effect of -2 bars of osmotic drought e

Starch is a promising polymer for creating novel microparticulate systems with superior biocompatibility and controlled drug delivery capabilities. In this study, we synthesized polyethylene glycol (PEG)-modified starch microparticles and encapsulated folic acid using a solvent-mediated acid-base precipitation method with magnetic stirring, which is a simple and effective method. To evaluate particle degradation, we simulated physiological conditions by employing an enzymatic degradation approach. Our results with FTIR and SEM confirmed the successful synthesis of starch–PEG microparticles enc

Pd(PPh3)4 in PEG-400 is shown to be a highly efficient catalyst for the Stille cross-coupling reactions of various organotin compounds with aryl bromides. The reaction could be conducted at 80 °C using NaOAc as base, yielding a variety of biaryls, alkynes and alkenes in good to excellent yields. The isolation of the products was readily performed by extraction with petroleum ether and the Pd(PPh3)4/PEG-400 system could be easily recycled and reused five times without any significant loss of activity.
