Abstract:

In this study, nanoliposome-loaded poly(hexamethylene biguanide) is introduced as a novel biocompatible antibacterial product with higher activity than microliposomes. Soy lecithin as a clean product was used to prepare various nanoliposomes through sonication, high-pressure homogenizer, and normal homogenizer and also microliposomes through two methods of lipid film hydration and incubation methods. The nanoliposomes were formed under sonication with the size of 50 nm. The prepared liposomes were then loaded with poly(hexamethylene biguanide chloride) and the inclusion percentage was measured

Abstract:

Poly(L-lactic acid) (PLA) has good mechanical properties and is biodegradable. However, its crystallization rate is slow, crystallization period long, and its crystallization temperature high at 116 °C. Consequently, long processing cycles are required for the production of high crystallinity poly (L-lactic acid). Addition of nucleating agents is an efficient way to solve this problem. Aliphatic amide such as N,N-ethylenebis(12-hydroxystearamide) and ethylenebis-stearamide are reported as nucleating agents for poly (L-lactic acid). In this study, the effect of the aliphatic polyamide, poly (he

Abstract:

Poly(hexamethylene guanidine) has been used for several decades as a disinfectant for various surfaces and water, including drinking water. Its use has increased significantly due to the COVID-19 pandemic. The toxicity of poly(hexamethylene guanidine) has been studied on warmblooded animals and fish, but there is little data on its action on planktonic organisms. For the first time the effect of poly(hexamethylene guanidine) (Anavidin preparation) on diatom algae which are one of the main producers of oxygen and photosynthesized organic substances was studied.

Abstract:

The relationship between cell proliferation and differentiation has long been a source of controversy. Stimulation of normal erythroid maturation results in a finite number of cell divisions accompanied by a concomitant accumulation of hemoglobin. Friend erythroleukemia cells treated with hexamethylene bisacetamide differentiate in a similar manner, while agents such as hemin apparently induce differentiation without limiting cell proliferation. Aphidicolin, an inhibitor of DNA synthesis, has been reported to induce differentiation in the absence of cell proliferation. Using these three chemic

Abstract:

1. Leucocyte Na+/H+ exchange and intracellular pH were investigated in physiological buffer containing bicarbonate. 2. The amiloride analogue 5-(N,N-hexamethylene) amiloride (1 × 10−5 mol/l), an inhibitor of Na+/H+ exchange, had no significant effect on resting leucocyte pH, Na+ influx or Na+ content. 3. Ammonium chloride washout induced a profound intracellular acidosis, stimulating Na+/H+ exchange. This led to a 236% increase in Na+ influx. Eighty-eight per cent of this increase was inhibited by 5-(N,N-hexamethylene) amiloride. This demonstrates that 5-(N,N-hexamethylene) amiloride is an eff

A series of adamantane (AD)-containing polyurethanes were prepared from 1,3-adamantanediol, 1,4-butanediol and hexamethylene diisocyanate, and the influences of AD on the shape memory behavior of polyurethanes were systematically studied.

Abstract:

Copolyurea networks (co-UNs) were synthesized via crosslinking polymerization of a mixture of tetrakis(4-aminophenyl)methane (TAPM) and melamine with hexamethylene diisocyanate (HDI) using the organic sol-gel polymerization method. The subsequent thermal treatment of between 200 and 400 °C induced the sintering of the powdery polyurea networks to form porous frameworks via urea bond rearrangement and the removal of volatile hexamethylene moieties. Incorporating melamine into the networks resulted in a higher nitrogen content and micropore ratio, whereas the overall porosity decreased with the

Abstract:

Polymerization of citric acid and hexamethylene diisocyanate and hydrolysis results in a polyelectrolyte PHMC. Noncovalent cross-linking of cooperative H-bonding units stabilizes the self-assembly of the PHMC chains into nanoparticles in water.

Abstract:

The effectiveness of preploymer and 1,6-Hexamethylene diamine encapsulated by double-walled microcapsules based polyurea (PUA) was explored for healing the cracks generated in epoxy coatings. Double-walled microcapsules were systhesized by interfacial polymerization at the interface between the prepolymer droplets and the 1,6-Hexamethylene diamine droplets to form the polyurea shell. The effect of synthetic stirring speed on the morphology of the microcapsules was observed by scanning electronmicroscopy (SEM) and optical microscopy (OM). The chemical structure as well as the thermal properties

Abstract:

We prepared injectable cationic hydrogels with strong antibacterial activity and remarkably low toxicity by in situ thiol–ene “click” reaction between dimethacrylate terminated poly(hexamethylene guanidine) (PHMGDMA) and poly[oligo(ethylene) glycol mercaptosuccinate] (POEGMS) under physiological conditions.
