Results indicate that lateral-diffusion and systemic redistribution of the API following topical application of the drug product were negligible, thus MTZ measured by dMD can be selectively attributed to the dermal bioavailability of the API from the applied topical dose. The dMD methodology was able to detect differences in the bioavailability of MTZ from the cream compared to the gel when applied at the same dose, as well as among different doses of the same formulation over a 48-hour sampling duration; therefore, the method is sensitive. The percentage loss of D3-MTZ from the probe compared to its original concentration in the perfusate indicates that the probe performance was stable over the 48 h.

Physical inactivity, in addition to clinical factors, has been associated with higher levels of late pelvic symptoms in patients with prostate cancer (PCa) after radiation therapy. The aim of this study was to investigate the effect of a structured multicomponent exercise program comprised of aerobic and resistance training as well as impact loading on the prevalence and severity of symptoms commonly resulting from androgen deprivation therapy (ADT) and pelvic radiation therapy.

We performed a secondary analysis of pooled data from 2 randomized controlled trials that investigated the role of exercise on treatment-related side effects in patients with PCa receiving ADT. Patients were included in the analysis if they had undergone radiation therapy during the intervention in addition to ADT. Patient-reported quality of life and functional and symptom scales were assessed using the European Organization for Research and Treatment of Cancer QLQ-C30 and PR25 before and after 6 months of exercise or usual care d adverse effects in patients with PCa undergoing radiation therapy and ADT should be actively encouraged.

Exercise during concomitant hormone and radiation treatment for men with PCa may mitigate some adverse changes in patient-reported fatigue, physical functioning, and possibly sexual activity. The promotion and provision of exercise to counter a range of treatment-related adverse effects in patients with PCa undergoing radiation therapy and ADT should be actively encouraged.Powders are usually dispensed, blended, and transferred between different manufacturing steps in so-called Intermediate Bulk Containers (IBCs), and discharge from an IBC plays a critical role in the ability to manufacture high-quality tablets. To better understand IBC discharge, the flow behavior of selected excipients was comprehensively characterized using a number of techniques including the Hausner ratio/Carr's index, Erweka flow test, FlowPro flow test, shear test and wall friction test as well as FT4 powder rheometer experiments. Jenike's hopper design methodology was then used to predict the minimum non-arching outlet diameter and the mode of flow. Furthermore, the discharge rate from an IBC was predicted using a simple model that takes into account gravity and aerodynamic drag. Selleckchem Spautin-1 The predictions were experimentally verified by measuring the discharge rate from a 20 L IBC using five commonly-used excipients. The small-scale Erweka flow test provided the best prediction of the full-scale IBC discharge experiment. Furthermore, a simple model that relied only on the particle size of the material and the diameter of the discharge opening was found to predict the IBC discharge rate remarkably well.Anti-inflammatory treatment options for cystic fibrosis (CF) patients are currently limited and as such, there is an imperative need to develop new anti-inflammatory agents to reduce the persistent inflammation present within CF lungs. This study explored the potential of Diclofenac (DICLO) as a novel inhaled anti-inflammatory drug for CF treatment. The anti-inflammatory activity of DICLO on an air-liquid interface (ALI) cell culture model of healthy (NuLi-1) and CF (CuFi-1) airways showed a significant reduction in the secretion of pro-inflammatory cytokines, IL-6 and IL-8. Therefore, pressurized metered dose inhaler (pMDI) DICLO formulations were developed to allow targeted DICLO delivery to CF airways. As such, two pMDI DICLO formulations with varying ethanol concentrations 5% (w/w) equating to 150 µg of DICLO per dose (Low dose), and 15% (w/w) equating to 430 µg of DICLO per dose (High dose) were developed and characterized to determine the optimum formulation. The Low dose pMDI DICLO formulation showed a significantly smaller particle diameter with uniform distribution resulting in a greater aerosol performance when compared to High dose formulation. Consequently, the Low dose pMDI DICLO formulation was further evaluated in terms of in vitro transport characteristics and anti-inflammatory activity. Importantly, the DICLO pMDI displayed anti-inflammatory activity in both healthy and CF in vitro models, highlighting the potential of an aerosolized low-dose DICLO formulation as a promising inhaled anti-inflammatory therapy for CF treatment.Cancer immunotherapy is becoming an important option for malignant tumors treatment. Unfortunately, lacking intratumoral infiltration of cytotoxic T lymphocytes (CTLs) and immunosuppressive tumor microenvironment (ITM) remian primary barriers that immensely hamper its further clinical application. For boosting immune response and rebuilding the ITM, valid hybrid micelles (SK/siIDO1-HMs) delivering shikonin (SK) and IDO-1 knockdown siRNA (siIDO1) were conducted. SK/siIDO1-HMs had sufficient circulation time, favorable intratumoral accumulation and rapidly release in the cytoplasm. Importantly, SK was demonstrated to significantly elicit intratumoral accumulation of CTLs through inducing immunogenic cell death (ICD) of tumor cells. Moreover, siIDO1 downregulated the IDO-1-caused immunosuppression and restrained regulatory T lymphocytes (Tregs). In summary, SK/siIDO1-HMs displayed a remarkable potential for tumor therapy via triggering the ICD and moderating the IDO-1-triggered immunosuppression.Tribology is an emerging technique in the pharmaceutical field for texture and mouthfeel studies. Due to its relevance to oral sensory perception, tribology supports the development of novel products in the food industry. This study explores tribology as a tool to optimise the mouthfeel and ease of swallowing of pharmaceutical coatings and coated tablets. We measured the lubricating properties of eight pharmaceutical coatings using two methods surface tribology and thin film tribology. As food science is more advanced in texture and mouthfeel studies, methods were developed from this field with the intention to mimic tablet ingestion. Further, the link between tribological measurements and the sensory evaluation of the coated tablets obtained by a human panel was explored. We have demonstrated that discrimination of tablets with different coatings using tribology is feasible. The viscosity, solubility and composition of the coating formulations played an important factor in lubrication. For the first time, tribology was used to analyse the lubricating properties of conventional tablet coatings and a linear relationship between tribology and the oral sensory perception, i.
