The use of eponyms honours those who have contributed to the development of medicine and facilitates communication between colleagues. Eponyms are based on historical knowledge to know who was the first to use a given technique. In the previous century, two different operative procedures have been attached to the 'so called' Bernard lower lip reconstruction. This historical literature on lip reconstruction with a focus on the years 1853-1855 elucidates the roles of Bernard, Saeman, Desgranges and Burow, and gives suggestions for eponyms that do justice to the innovating surgeons Bernard, Burow and Desgranges...

Oligodendrocyte precursor cell (OPC) development into myelinated oligodendrocytes demands vigorous membrane addition. Since myristoylated alanine-rich C-kinase substrate (MARCKS) reportedly contributes to Ras-associated protein (Rab)-10-associated vesicle insertion into neuronal membranes, we investigated the role of MARCKS in OPC maturation. We found that either knockdown of MARCKS or interruption of its interaction with Rab10 would cause a decrease of the cell membrane area during OPC development. Enhanced MARCKS phosphorylation by Nogo66 or myelin debris treatment inhibited OPC maturation, while its dephosphorylation by protein phosphatase 2 A activator D-erythro-sphingosine promoted OPC development in the presence of myelin debris...

MiRNAs are important post-transcriptional regulators of gene expression. MiRNA expression is a crucial part of host responses to bacterial infection, however there is limited knowledge of their impact on the outcome of infections. We investigated the influence of miR-21 on macrophage responses during infection with Listeria monocytogenes, which establishes an intracellular niche within macrophages. MiR-21 is induced following infection of bone marrow-derived macrophages (BMDMs) with Listeria. MiR-21(-/-) macrophages display an increased bacterial burden with Listeria at 30 min and 2 h post-infection...

Multimodal polymeric nanoparticles have many exciting diagnostic and therapeutic applications, yet their uptake and passage by the placenta, and applications in the treatment of pregnancy complications have not been thoroughly investigated. In this work, the maternal-fetal-placental biodistribution of anionic and cationic multimodal poly(glycidyl methacrylate) (PGMA) nanoparticles in pregnant rats at mid (ED10) and late (ED20) gestation was examined. Fluorescently-labelled and superparamagnetic PGMA nanoparticles functionalized with/without poly(ethyleneimine) (PEI) were administered to pregnant rats at a clinically-relevant dose and biodistribution and tissue uptake assessed...

We aimed to assess lung fluid balance before and after gradual ascent to 5150m. Lung diffusion capacity for carbon monoxide (DLCO), alveolar-capillary membrane conductance (DmCO) and ultrasound lung comets (ULCs) were assessed in 12 healthy lowlanders at sea-level, and on Day 1, Day 5 and Day 9 after arrival at Mount Everest Base Camp (EBC). EBC was reached following an 8-day hike at progressively increasing altitudes starting at 2860m. DLCO was unchanged from sea-level to Day 1 at EBC, but increased on Day 5 (11±10%) and Day 9 (10±9%) vs...

We previously demonstrated a role for the myristoylated alanine-rich C kinase substrate (MARCKS) to serve as an adaptor protein in the anionic phospholipid phosphate-dependent regulation of the epithelial sodium channel (ENaC). Both MARCKS and ENaC are regulated by proteolysis. Calpains are a family of ubiquitously expressed intracellular Ca(2+)-dependent cysteine proteases involved in signal transduction. Here we examine the role of calpain-2 in regulating MARCKS and ENaC in cultured renal epithelial cells and in the mouse kidney...

Lung cancer is the leading cause of cancer-associated mortality in the United States. Kinase hyperactivation is a known mechanism of tumorigenesis. The phosphorylation status of the plasma membrane-associated protein myristoylated alanine rich C-kinase substrate (MARCKS) effector domain (ED) was previously established as being important in the sensitivity of lung cancer to radiation. Specifically, when MARCKS ED was in a non-phosphorylated state, lung cancer cells were more susceptible to ionizing radiation and experienced prolonged double-strand DNA breaks...

Tools for editing the genome and epigenome have revolutionised the field of molecular biology and represent a new frontier in targeted therapeutic intervention. Although efficiencies and specificities of genome editing technologies have improved with the development of TALEs and CRISPR platforms, intracellular delivery of these larger constructs still remains a challenge using existing delivery agents. Viral vectors, including lentiviruses and adeno-associated viruses, as well as some non-viral strategies, such as cationic polymers and liposomes, are limited by packaging capacity, poor delivery, toxicity, and immunogenicity...

Germline variation in solute carrier organic anion (SLCO) genes influences cellular steroid uptake and is associated with prostate cancer (PCa) outcomes. We hypothesized that, due to its steroidal structure, the CYP17A inhibitor abiraterone may undergo SLCO-mediated transport and that SLCO gene variation may influence intracellular abiraterone levels and outcomes.<br /><br />Experimental Design: Steroid and abiraterone levels were measured by mass spectrometry in serum and tissue from 58 men with localized PCa in a clinical trial of LHRH agonist plus abiraterone acetate plus prednisone for 24 weeks prior to prostatectomy...

BACKGROUND: Informal care is essential for many people with dementia (PwD), but it often results in a considerable burden for the caregiver. The perseverance time instrument integrates the aspect of perceived burden with the caregiver's capacity to cope with the burden, in contrast to most available instruments, which measure solely the burden of caregiving. The aim of this study was to extend insight into psychometric properties of the perseverance time instrument, specifically the construct validity, responsiveness, and predictive validity, within the population of informal caregivers for PwD...

Naturally occurring pyridone alkaloids as well as synthetic derivatives were previously shown to induce neurite outgrowth. However, the molecular basis for this biological effect remains poorly understood. In this work, we have prepared new pyridones, and tested the effect of thirteen 4-hydroxy-2-pyridone derivatives on the components of the endocannabinoid system. Investigation of binding affinities towards CB1 and CB2 receptors led to the identification of a compound binding selectively to CB1 (12). Compound 12 and a closely related derivative (11) also inhibited anandamide (AEA) hydrolysis by fatty acid amide hydrolase...

REVIEW
C M Stekelenburg, R E Marck, P D H M Verhaegen, K W Marck, P P M van Zuijlen
Patients with burn scars often experience functional problems because of scar contractures. Surgical treatment may be indicated for those burn scar contractures. If the contractures are small and linear, the contraction bands can be treated with local transposition flaps like the Z-plasty. Broader, diffuse contractures are more challenging and require a different surgical approach, such as the use of local tissue. The use of perforator-based flaps is promising; however, their true clinical significance for this type of burn reconstructions still needs to be determined...
