Hemostatic radiotherapy: a narrative review of the literature.

Background And Objective: In locally advanced cancer, bleeding is a common clinical presentation and radiotherapy (RT) provides a noninvasive, well-tolerated, cost-effective treatment. However, the choice for fractionation dose and schedule seem to merely depend on physician's preference rather than specific guidelines. We reviewed the available literature on palliative hemostatic RT for response rate (RR) and bleeding duration in relation with the given dose.

Foot biomechanics in patients with advanced subtalar- and mid-tarsal joint osteoarthritis and poorly responding to conservative treatment.

Background: A comprehensive insight into the effects of subtalar- and mid-tarsal joint osteoarthritis on lower limb's biomechanical characteristics during walking is lacking. Our goal was to assess joint kinematics and kinetics and compensatory mechanisms in patients with subtalar and mid-tarsal joint osteoarthritis.

Methods: Patients with symptomatic and radiographically confirmed osteoarthritis of the subtalar and mid-tarsal (n = 10) and an asymptomatic control group (n = 10) were compared.

Fast in vitro hydrolytic degradation of polyester urethane acrylate biomaterials: structure elucidation, separation and quantification of degradation products.

Synthetic biomaterials have evoked extensive interest for applications in the field of health care. Prior to administration to the body a quantitative study is necessary to evaluate their composition. An in vitro method was developed for the quick hydrolytic degradation of poly-2-hydroxyethyl methacrylate (pHEMA), poly(lactide-co-glycolide50/50)1550-diol (PLGA(50:50)(1550)-diol), PLGA(50:50)(1550)-diol(HEMA)(2) and PLGA(50:50)(1550)-diol(etLDI-HEMA)(2) containing ethyl ester lysine diisocyanate (etLDI) linkers using a microwave instrument.

Matter of age: growing anisotropic gold nanocrystals in organic media.

We investigated the influence of the reduction state of gold ions on the growth of gold nanocrystals in N,N-dimethyl formamide (DMF). While freshly prepared solutions of AuCl3 produce spherical nanocrystals, aged precursor solutions containing mainly Au+ ions and Au(0) atoms lead to various branched nanoparticles. Furthermore, we show that also the amount of the reducing and stabilisation agent tetra-n-octylammonium formate (TOAF) plays a decisive role on the shape of the nanocrystals, allowing us to grow triangular and cubic nanoparticles.

A simple method for measuring the size of metal nanoclusters in solution.

The connection between quantum size effects and the surface plasmon resonance of metal nanoclusters is introduced and the pros and cons of in situ and ex situ cluster analysis methods are outlined. A new method for estimating the size of nanoclusters is presented. This method combines core/shell cluster synthesis, UV-visible spectroscopy, and Mie theory.
