Rutin (Ru) is a flavonol glycoside, has significant scavenging characteristics against various reactive oxygen species, which exploits for widespread pharmacological activities such as ...anti-inflammatory and anti-allergic effects. This study aims to improve the bioavailability of iron oxide nanoparticles (IONPs) by coating them with Ru (Ru-IONPs). Considering this, IONPs and Ru-IONPs were prepared and characterized via various physical techniques. In addition, atomic absorption spectroscopy (AAS) has been used to assess the bio-distribution of the prepared formulation in vivo. Results revealed that the prepared IONPs and Ru-IONPs have a spherical shape with an average diameter of about 8 nm and 10 nm, respectively. Their surface potentials were found to be −19 ± 3.9 and −29.5 ± 5.4 mV, respectively. In vivo results revealed that single dose of IV administration of IONPs (16 mg/kg) elevated oxidative stress, indicated by the reduction of GSH in both heart and liver tissues, and increased their MDA contents. Also, IONPs administration resulted in hepatotoxicity characterized by a significant increase in ALT and AST levels in addition to cardiotoxicity characterized by a significant increase in CK-MB and LDH, in addition to the downregulation of heat shock protein 70 (HSP70) expression, while upregulation of TNF-α expression in both heart and liver tissues. Conversely, nearly all of these alterations were significantly ameliorated for animal groups administrated Ru-IONPs and the morphological injury’s counteraction in both heart and liver tissues. Therefore, we suggest that Ru could be used to alleviate the harmful effects and damages associated with IONPs administration due to its antioxidant, anti-inflammatory, and free radical scavenging properties.
Abstract Background Elderly patients often need post-acute care after hospital discharge. Involvement of social workers can positively affect the discharge planning process. Aim To investigate the ...effect of screening patients at risk for post-acute care needs by social workers on time with respect to social workers’ notification, length of stay and delays in discharge compared to usual care. Methods Cluster randomized stepped wedge trial design for five clusters (wards) and two steps (control to intervention) was used. A total of 400 patients (200 per period) with high risk of post-acute care needs (defined as Post-Acute Care Discharge score, PACD ≥ 7) were included. Social workers performed a screening to decide about self-referral to their services (intervention period), which was compared to a highly structured standard SW notification by physicians and nurses (control period). A Generalized Estimating Equations model adjusted the clustering and baseline differences. Results A total of 139 patients were referred to social services (intervention: n = 76; control: n = 63). Time to social workers’ notification was significantly shorter in the intervention period when adjusted for all the differences in baseline (Mdn 1.2 vs 1.7, Beta = -0.73, 95%-CI 1.39 to -0.09). Both the length of stay and the delayed discharge time in nights showed no significant differences (Mdn 10.0 vs 9.1, Beta = -0.12, 95%-CI 0.46 to .22 nights 95%-CI, resp. Mdn 0.0 vs 0.0, Beta = .11, 95%-CI -0.64 to 0.86). Conclusion Screening speeded up social workers’ notification but did not accelerate the discharge processes. The screening by social workers might show process improvement in settings with less structured discharge planning.
The impact of a soluble complex (SC) of curcumin (CuR) synthesized using hot melt (HM) and hot-melt extrusion (HE) technologies on adenocarcinoma cells for the treatment of colorectal cancer by ...enhancing CuR solubility is investigated in this work. In silico molecular modelling, solubility, drug release, and physicochemical analysis were all part of the phase solubility (PS) study, which featured a novel dyeing test and a central composite design to optimize the best complex (CDD). The optimal HE-SC (1 : 5) enhances solubility (0.8521 ± 0.016 mg·mL−1) and dissolution (91.87 ± 0.208% at 30 min), and it has an ideal stability constant (309 and 377 M−1) at 25 and 37°C and an AL type of isotherm, implying 1 : 1 stoichiometry according to the findings. An intermolecular hydrogen bond that has not undergone any chemical change and has resulted in the complete conversion of the amorphous form aids in the creation of SC. In vitro cytotoxicity was measured at IC50 on the SW480 (72 M·mL−1) and Caco-2 (40 M·mL−1) cells. According to apoptotic studies, apoptosis was responsible for the vast majority of cell death, with necrosis accounting for a small proportion of the total. In vivo toxicity was established using a zebrafish model, and a western blot examination revealed apoptosis at the molecular level. It was argued that the novel formulations developed using HE technology are more significant and effective than existing pure CuR formulations.
Objective: The main objectives of the present investigation work included that the preparation of a suitable naproxen semi-solid dosage form by using different types of semi-solid bases (gel bases, ...ointment bases) for topical application for the effective treatment of muscle aches.
Methods: Different types of semi-solid bases (gel bases and ointment bases) were successfully prepared by the incorporation method to know the effect of semi-solid bases on drug release from topical semi-solid formulations. In all formulations, the drug was added by the levigation method. An evaluation study of prepared formulations, includes physical appearance, spreadability, extrudability, pH was conducted according to official methods.
Results: Percent drug release of all formulations was conducted by taking diffusion cells with cellophane membrane and results showed that gel-based formulations showed more drug release than ointment-based formulations. Carbopol gel base (F1) showed more drug release (98.76 %), simple ointment base formulation (F8) showed least drug release (25.11%). From the stability studies reports at various temperature and humidity conditions it is evident that all formulations are stable for one month. In all the formulations, the drug content was observed at 95.75%.
Conclusion: Finally concluded that the NXN topical dosage forms can be prepared by using gel-type bases preferably than ointment bases to release more drug from formulations.
A review on a medicinal plant belong to family Labiatae has been made in the Kingdom of Saudi Arabia. Among the reported flora in the Kingdom of Saudi Arabia, Labiatae family has the highest species. ...A total of 23 species of Labiatae family has been reported with high medicinal value. A detail review on 12 species of Labiatae family had done to know their phytochemical constituents, medicinal uses and pharmacological properties.

The summarized information from the current review may be a useful tool for researchers to carry out further study and explore other scientific aspects of the herbs.
Alzheimer's disease is the extremely popular cause of dementia that causes memory loss. People who have Alzheimer's disease suffer from a disorder in neurodegenerative which leads to loss in many ...brain functions. Nowadays researchers prove that early diagnosis of the disease is the most crucial aspect to enhance the care of patients' lives and enhance treatment. Traditional approaches for diagnosis of Alzheimer's disease (AD) suffers from long time with lack both efficiency and the time it takes for learning and training. Lately, deep-learning-based approaches have been considered for the classification of neuroimaging data correlated to AD. In this paper, we study the use of the Convolutional Neural Networks (CNN) in AD early detection, VGG-16 trained on our datasets is used to make feature extractions for the classification process. Experimental work explains the effectiveness of the proposed approach.
