Oral drug delivery is the most common route of drug administration. Nevertheless, there are some important limitations that reinforce the need for developing new drug delivery systems. Mucoadhesive oral films (MOF) are promising dosage forms that adhere to the oral mucosa and deliver the drug through it, which present several advantages. These include: bypassing the hepatic first pass effect, fast onset of action, ease of transportation and handling. The use of such dosage form is beneficial for ...

The phenolic compounds present in 29 samples of olive fruits were analysed by reversed-phase HPLC/DAD and/or HPLC-DAD/ESI-MS/MS. All samples were collected during the normal picking period for olive oil production, in north and central Portugal, and were obtained from 18 different olive cultivars. Two different extraction methods were necessary for the complete quantification of phenolic compounds, a methanolic extraction and an extraction which included a solid-phase extraction (SPE) cleaning step. ...

Successful management of HIV infection as a chronic condition has resulted in a demographic shift where the proportion of people living with HIV (PLWH) older than 50 years is steadily increasing. A dedicated clinic to PLWH older than 50 years was established at Chelsea and Westminster Hospital in January 2009 and then extended to HIV services across the directorate. We report the results of a service evaluation reviewing 10 years of activities of this clinic between January 2009 and 2019. We aimed ...

Abstract This paper focuses on the quality level choice, emphasising and formally showing the complete role of market structure and strategic interaction between firms on this choice. Historically, the most used model supporting the quality decision is the prevention-appraisal-failure model, which is based solely on the minimisation of the cost of quality. However, as is well known, the quality decision should follow from profit maximisation, thus leading to a higher quality level than the one derived ...

The diagnosis of parathyroid carcinomas is often difficult. HRPT2 mutations have been identified in familial [hyperparathyroidism-jaw tumor (HPT-JT) syndrome] and sporadic parathyroid carcinomas, supporting that HRPT2 mutations may confer a malignant potential to parathyroid tumors. In this study, we report the clinical, histopathological, and genetic investigation of two unrelated cases, whom had apparently sporadic malignant parathyroid tumors, initially diagnosed as adenomas. In one case, the differential ...

Concomitant use of different drugs and their potential interactions may increase anticholinergic exposure and escalate the risk for side effects. We conducted an analysis in our cohort of people living with HIV over 50 years of age to evaluate the overall anticholinergic risk, as it is useful to identify, prevent, and manage increased side effect risks.
