Selective Modifications of Sheep Wool Usable in Non-Textile Applications.

The traditional textile use of wool as a valuable renewable material needs alternative applications in order to, besides sheep milk and meat, valorize currently unnecessary wool. Each type of product containing sheep wool requires wool with customized properties. Finding suitable physical and chemical modifications needed to develop new products while minimizing harmful side effects is a challenge for scientists.

Prewetting Electron Beam Irradiated and Native Sheep Wool Can Affect Their Sorptivity.

In this work, the effect of prewetting native and electron beam-modified wool on the resulting sorption of Cu(II) from wool solutions was studied. The following conditions and combinations were applied: 6 mM and 50 mM solutions, prewetting time 0-24 h, contact time 1-24 h. The sorption results showed that wetting the wool before sorption from the low concentrated solution can fundamentally improve the efficiency of the separation process.

Persistence of denosumab in Slovak patients with bone metastases - a prospective observational study.

Background: An integrated analysis of phase III trials in patients with advanced solid tumors demonstrated superiority of denosumab over zoledronic acid in preventing skeletal-related events. A drug's clinical efficacy, however, depends on regular and continued administration (persistence); persistence in Slovak real-life is yet undetermined for denosumab in the oncology indication.

Patients And Methods: This was a single-arm, prospective, observational, non-interventional study in patients with bone metastases from solid tumors treated with denosumab every 4 weeks in real-world clinical practice in 5 European countries.

Competitive Adsorption of Cr(III) and Cu(II) on Electron Beam-Irradiated Sheep Wool from Binary Solutions Can be Controlled by the Absorbed Dose.

Sheep wool irradiated by an electron beam was tested for adsorption of Cr(III) and Cu(II) from binary solutions within the same concentration of each cation from 15 to 35 mmol·dm. The wool sorptivity examination was aimed at searching the effect of the dose absorbed by wool on simultaneous sorption of these cations due to surface and bulk changes. The partners affected each other under these conditions.

Sheep Wool Humidity under Electron Irradiation Affects Wool Sorptivity towards Co(II) Ions.

The effect of humidity on sheep wool during irradiation by an accelerated electron beam was examined. Each of the samples with 10%, 53%, and 97% relative humidity (RH) absorbed a dose of 0, 109, and 257 kGy, respectively. After being freely kept in common laboratory conditions, the samples were subjected to batch Co(II) sorption experiments monitored with VIS spectrometry for different lapses from electron beam exposure.
