Abstract Aims Richter's syndrome refers to high grade transformation of B-cell chronic lymphocytic leukaemia (CLL), usually to diffuse large B-cell lymphoma (DLBCL), as assessed by strict World Health Organisation (WHO)-defined histological criteria. Although a relatively evidence-poor area, the recommended clinical management of high grade transformation differs considerably from relapsed CLL. The 'CHOP-OR' trial was a single arm, multi-centre, non-randomised phase II NCRI trial in patients with newly diagnosed Richter's syndrome, recruiting from across the UK from April 2011 to... περισσότερα »

Age-associated decrease in GDNF and its cognate receptor GFRα-1 protein expression in human skin
Summary Glial cell line-derived neurotrophic factor (GDNF) and its cognate receptor (GFRα-1) are expressed in normal human skin. They are involved in murine hair follicle morphogenesis and cycling control. We hypothesize that ‘GDNF and GFRα-1 protein expression in human skin undergoes age-associated alterations. To test our hypothesis, the expression of these proteins was examined in human skin specimens obtained from 30 healthy individuals representing three age groups: children (5–18 years), adults (19–60 years) and the elderly (61–81 years).

Chirp Stimuli in ABR/ASSR Measurement
Update on Auditory Evoked Responses: Value of Chirp Stimuli in ABR/ASSR Measurement: When I first heard about chirps many years ago, none of the clinical ABR systems had chirps as stimuli. As time went on, some of the manufacturers began to introduce chirps. As with any other new development, they were heavily promoted. However, I was not going to start using a new type of stimulus when the existing stimuli - traditional tone bursts and clicks - worked just fine. I kept an open mind, but I looked for evidence. Today, there is plenty of evidence for the use of chirps.

The mode transition is realized in a real-time manner according to the charging or discharging current.... περισσότερα »
Peptide drugs accelerate BMP-2-induced calvarial bone regeneration and stimulate osteoblast differentiation through mTORC1 signaling
Both W9 and OP3-4 were known to bind the receptor activator of NF-κB ligand (RANKL), inhibiting osteoclastogenesis. Recently, both peptides were shown to stimulate osteoblast differentiation; however, the mechanism underlying the activity of these peptides remains to be clarified. A primary osteoblast culture showed that rapamycin, an mTORC1 inhibitor, which was recently demonstrated to be an important serine/threonine kinase for bone formation, inhibited the peptide-induced alkaline phosphatase activity. Furthermore, both peptides promoted the phosphorylation of Akt and S6K1, an ... περισσότερα »

Seizures are common among patients with brain tumors. Transient, postictal magnetic resonance imaging abnormalities are a long recognized phenomenon. However, these radiographic changes are not as well studied in the brain tumor population. Moreover, reversible neuroimaging abnormalities following seizure activity may be misinterpreted for tumor progression and could consequently result in unnecessary tumor-directed treatment. Here, we describe two cases of patients with brain tumors who developed peri-ictal pseudoprogression and review the relevant literature. Case Rep Oncol 2016;... περισσότερα »
