Published: August 2024

Abstract
Metal–organic frameworks (MOFs) have attracted chemical and material research interests in recent years due to their incredibly prominent properties and unique structures. Although MOFs have many unique characteristics, including tunable pore structures and functionality, their application performances are hindered by their powdered crystalline state, intrinsic fragility, poor processability, and stability. Recent studies have shown that the incorporation of MOFs into hydrogel outperforms the MOFs in their crystalline state. This article presents the current development of stimulus-responsive MOF–hydrogel composites in terms of synthesis of MOF and preparation of MOF–hydrogel, characterization, and advancement of stimulus-responsive MOF–hydrogel composite in drug delivery and wound management. The article also discusses prospective study directions, delineating potential avenues for further exploration and innovation in this dynamic field.

Published: August 2024

In this paper, the adsorption of trivalent chromium cations by a sample of sodium-modified TiO2 was studied. XRF analysis of the TiO2 surface was performed. The dependence of the adsorption value on the duration of the interaction in the system of the adsorbent–solution of chromium compound was investigated. The influence of the acidity of the solution and the equilibrium concentration of chromium ions on the adsorption value was also determined. It is shown that the adsorption kinetics of trivalent chromium ions is best described by the pseudo-second-order equation and the diffusion kinetic model. Freundlich's adsorption theory best describes equilibrium adsorption. Mass spectrometry proved the enhanced adsorption of trivalent chromium ions from a mixture with hexavalent chromium. This statement was evidenced by Raman spectroscopy of the surface of Na-TiO2. The maximum adsorption of Cr (III) ions is 62 mg/g. The separation factor of trivalent chromium and hexavalent chromium is 7.279

My name is Richard Khalifa Diggs, Khalifa being an attribute that I adopted in 1977 at the Allegheny County Jail. I’m in for a double homicide on a life sentence without parole. I’ve been down nineteen years, six months, and seven days as of this morning.
I work at the operations building here at SCIP, the State Correctional Institution at Pittsburgh. About eight years ago I worked in this same building, and I was always somehow drawn to this particular spot at this window. It’s got pretty much a full view of the yard, pretty much a view of the institution overall, and from here, I see a lot of me and three or four generations of me. Just running around playing handball, basketball, tag, lifting iron, playing cards, planting heads [killing people]. It’s a senseless maze of confused people, of which I include myself. It’s almost horrible to the extent that you sit here and you realize that you’re very much a part of this.

BackgroundHyperglycemia interrupts wound healing, causing persistent and non-healing wounds. Phaleria macrocarpa extract (PME) has anti-diabetic, anti-inflammatory, antimicrobial, and antioxidant properties. This study aimed to assess P. macrocarpa activity on skin wound healing in diabetic rats.
MethodsAn experimental study performed on 25 male Wistar rats. Ointments were prepared by adding vehicle (w/w) to PME at the desired concentration. Diabetes was induced by injecting rats with nicotinamide (NAD) 230 mg/kg and streptozotocin (STZ) 65 mg/kg. After hyperglycemia was confirmed, animals were randomly grouped into: i) normal rats, ii) diabetic rats; iii) diabetic rats + 2.5% ointment; iv) diabetic rats +5% ointment; and v) diabetic rats +10% ointment. Full-thickness skin wounds were induced on the dorsum and treatment was applied daily for 3 and 7 days, respectively. On days 4 and 8, wound closure was measured and animals were sacrificed for tissue samples. Wound healing was evaluated by measuring malondialdehyde (MDA) in tissue homogenates of the dermal wounds and analyzing histological changes by hematoxylin-eosin and Sirius-red staining.
ResultsPME 10% ointment improved MDA levels and wound closure of inflammatory and proliferation phases. In inflammatory phase, 5% and 10% ointment reduced inflammation severity compared with diabetic rat group (p<0.05). In proliferation phase, PME 10% ointment group had a higher wound histological score (characterized by epidermal regeneration, fibroblast count, granulation tissue, and angiogenesis), and higher collagen bundle density compared with untreated groups (p<0.05).
ConclusionsTopical P. macrocarpa improves inflammatory and proliferation phases of excision wound healing in type 2 diabetes.
