    Abstract Introduction: Nanotechnology always seeks to provide new solutions for targeted delivery of chemotherapy drugs, in order to increase the quality of cancer treatment and reduce the side effects of chemotherapy. The aim of this study was to load the anticancer drug doxorubicin on Magnetic iron oxide nanoparticles were subjected to physico-chemical evaluation for their effect on MCF-7 cells. Methods: This research was a descriptive-analytical study. In this laboratory research, iron oxide nanoparticles were first synthesized by precipitation method. Then they were coated with polyethylene imine and gold. After loading the drug doxorubicin into the magnetic iron oxide nanoparticles, the physiochemical parameters of the nanosystem from the point of view of insertion efficiency, drug release profile under similar conditions of healthy and cancer cells, size, zeta potential and morphology were determined. Results: The magnetic nanocarriers had a diameter of 90 nm and a zeta potential of 66.7 mV. The maximum release of the drug from the nanosystem at 37°C, pH=7.4 and 42°C, pH=5.4 and after 48 hourswas 48% and 66%, respectively. The SEM analysis showed the spherical morphology and the absence of chemical interaction between the nanosystem and the drug. The investigation of the performance of the nanosystem indicated an increase in the toxicity of encapsulated doxorubicin compared to free doxorubicin at similar concentrations on the MCF_7 strain. Conclusion: The results of this research showed that the magnetic iron oxide nanoparticle system, while having appropriate physiochemical characteristics, does not change the chemical nature of the drug and can be a suitable and semi-targeted carrier for the anticancer drug doxorubicin.

    Abstract Recycling and reuse of biomass waste in synthesis of nanomaterials have recently received much attention as an effective solution for environmental protection and sustainable development. Herein, nitrogen-doped carbon dots (N-CDs) with blue emission were synthesized from the orange peels as a precursor through a simple hydrothermal method and then, modified with ethylenediamine tetraacetic acid (N-CD@EDTA). The N-CD@EDTA was embedded as a fluorophore in Cu-based metal-organic framework (MOF-199) structure (N-CD@EDTA/MOF-199) to construct fluorescence sensor toward l-ascorbic acid (L-AA) determination. The N-CD@EDTA/MOF-199 nanohybrid significantly and selectively turned on toward L-AA determination during the fluorimetric experiments. Under optimal conditions, the probe showed a suitable linear response in the concentration range of 10 nM-100 μM with a low limit of detection (LOD) of 8.6 nM and high sensitivity of 0.201 μM

    Abstract Pandemics such as coronavirus disease 2019 (COVID-19) can manifest as systemic infections that affect multiple organs and show laboratory manifestations. We aimed to analyze laboratory findings to understand possible mechanisms of organ dysfunction and risk stratification of hospitalized patients in these epidemics.

    Abstract The current budesonide formulations are inadequate for addressing left-sided colitis, and patients might hesitate to use an enema for a prolonged time. This study focuses on developing a single-layer coating for budesonide pellets targeting the descending colon. Pellets containing budesonide (1.5%w/w), PVP K30 (5%w/w), lactose monohydrate (25%w/w) and Avicel pH 102 (68.5%w/w) were prepared using extrusion spheronization technique. Coating formulations were designed using response surface methodology with pH and time-dependent Eudragits. Dissolution tests were conducted at different pH levels (1.2, 6.5, 6.8, and 7.2). Optimal coating formulation, considering coating level and the Eudragit (S + L) ratio to the total coating weight, was determined. Budesonide pellets were coated with the optimized composition and subjected to continuous dissolution testing simulating the gastrointestinal tract. The coating, with 48% S, 12% L, and 40% RS at a 10% coating level, demonstrated superior budesonide delivery to the descending colon. Coated pellets had a spherical shape with a uniform 30 µm thickness coating, exhibiting pH and time-dependent release. Notably, zero-order release kinetics was observed for the last 9 h in colonic conditions. The study suggests that an optimized single-layer coating, incorporating pH and time-dependent polymers, holds promise for consistently delivering budesonide to the descending colon.
