Medical doctors in teaching hospitals aim to serve the two central goals of patient care and medical training. Whereas patient care asks for experience, expertise and close supervision, medical training requires space to practise and the 'invisibility' of medical residents. Yet current reforms in postgraduate medical training point to an ...

Results obtained from the end of the 1950s suggested that ionizing radiation could induce foetal malformations in some mouse strains when administered during early pre-implantation stages. Starting in 1989, data obtained in Germany also showed that radiation exposure during that period could lead to a genomic instability in the surviving ...

Lymphocyte development occurs in a stepwise progression through distinct developmental stages. This ordered maturation ensures that cells express a single, non-autoreactive antigen receptor, which is the cornerstone of a diverse adaptive immune response. Expression of a mature antigen receptor requires assembly of the antigen receptor genes by the process of ...

A series of triterpene-based gamma-secretase modulators is optimized. An acetate present at the C24 position of the natural product was replaced with either carbamates or ethers to provide compounds with better metabolic stability. With one of those pharmacophores in place at C24, morpholines or carbamates were installed at the C3 ...

The metabolism of elzasonan has been examined in vitro using hepatic microsomes from human and recombinant heterologously expressed P450 enzymes (rCYP). Metabolism occurs primarily via oxidative N-demethylation to form M4 and oxidation reactions to form elzasonan N-oxide (M5) and 5-hydroxyelzasonan metabolite (M3). Additionally, elzasonan was shown to be metabolized to ...

Programmed cell death (PCD), referring to apoptosis, autophagy and programmed necrosis, is proposed to be death of a cell in any pathological format, when mediated by an intracellular program. These three forms of PCD may jointly decide the fate of cells of malignant neoplasms; apoptosis and programmed necrosis invariably contribute ...

Focal adhesions are large structures through which integrins and scaffold proteins link the actin cytoskeleton to the extracellular matrix. A detailed analysis of integrin dynamics now indicates that focal-adhesion-associated integrins constantly switch between active and immobilized, and unbound and free-diffusing states, with different fibronectin-binding integrin heterodimers showing distinct focal-adhesion dynamics.

A distinguishing feature of the lantibiotic family of cyclic peptides is the presence of thioethers. Treatment of a lantibiotic with an alkaline solution at high pH gives rise to a β-elimination reaction yielding the corresponding ring opened precursor, containing a dehydro-amino acid residue. We here reveal in a proof-of-concept study ...

Minimally invasive treatments of varicosis are increasingly establishing. Short and intermediate-term outcomes of endovenous treatments are satisfying: success rates are comparable with conventional surgery, whereas recovery is faster and complication rates are lower. Success rates are highest for endovenous laser ablation (EVLA). However, endovenous radiofrequency ablation (RFA) has advanced. Its ...

The standard formulation of tunneling transport rests on an open-boundary modeling. There, conserving approximations to nonequilibrium Green function or quantum statistical mechanics provide consistent but computational costly approaches; alternatively, the use of density-dependent ballistic-transport calculations (e.g., Lang 1995 Phys. Rev. B 52 5335), here denoted 'DBT', provides computationally efficient (approximate) atomistic ...
