Merkel Cell Carcinoma Mimicking a Pyogenic Granuloma on the Thumb.

Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer that can present with various clinical manifestations. An 80-year-old male, known to have chronic lymphocytic leukaemia presented with a lesion on his left thumb, initially thought to be a pyogenic granuloma. The lesion was cauterized with silver nitrate but remained persistent.

Nose-to-brain delivery of chrysin transfersomal and composite vesicles in doxorubicin-induced cognitive impairment in rats: Insights on formulation, oxidative stress and TLR4/NF-kB/NLRP3 pathways.

Many cancer survivors suffer from chemotherapy-induced cognitive impairment known as 'Chemobrain'. Doxorubicin -topoisomerase II inhibitor- is widely used in breast cancer, hematological cancers and other neoplasms. However, it is reported to precipitate cognitive impairment in cancer patients via inducing oxidative stress and inflammatory response.

Teaching life cycle assessment in higher education.

Purpose: Scientific Life Cycle Assessment (LCA) literature provides some examples of LCA teaching in higher education, but not a structured overview of LCA teaching contents and related competencies. Hence this paper aims at assessing and highlighting trends in LCA learning outcomes, teaching approaches and developed content used to equip graduates for their future professional practices in sustainability.

Methods: Based on a literature review on teaching LCA in higher education and a collaborative consensus building approach through expert group panel discussions, an overview of LCA learning and competency levels with related teaching contents and corresponding workload is developed.

Patella Height in Different Ethnic Populations: An Observational Multicenter Study.

Patella height appears to have a crucial role in knee biomechanics. Patellar malalignment and maltracking are therefore believed to be associated with development and progression of patellofemoral pain and disease. Published data are scant regarding the effect of everyday tasks on patella height and patellofemoral disease.
