Article Synopsis
  • FDA-approved anticoagulants can increase bleeding risks, including serious intracranial hemorrhages, but the specific effectiveness and safety of sulfonate polymers as alternatives have not been thoroughly studied.
  • Researchers synthesized and evaluated various sulfonated copolymers, finding that PSSS-based copolymers showed stronger anticoagulant effects compared to PAMPS-based ones, with the effectiveness influenced by sulfonate concentration and molecular weight.
  • The PEG-PSSS copolymer demonstrated significant anticoagulant activity in animal models and can be reversed by Heparin Binding Copolymer (HBC), targeting specific factors in the blood coagulation process, indicating potential for use in medical applications related to blood contact.

The assessment of hemostasis is necessary to make suitable decisions on the management of patients with thrombotic disorders. In some clinical situations, for example, during thrombophilia screening, the presence of anticoagulants in sample makes diagnosis impossible. Various elimination methods may overcome anticoagulant interference.

Aim: The aim of this study was to investigate recovery processes on pressure pain sensitivity and blood indicators in professional football players after three different post-game training modalities: standard recovery training, no physical activity, delayed onset muscle soreness reduction training.

Methods: Eleven male football field players participated in the present study. The experiment was performed in three sessions over three weeks after three football league games.

Reproductive fitness of carriers of heterochromatic variants of the human karyotype was found to be normal. The method was based on a comparison between known carriers and known non-carriers from the same pedigree in respect of live births, generation time and survival of offspring to reproductive age. A subset of the data had been included in an earlier study in which reproductive fitness of carriers was found to be significantly reduced.

Data on the families of 74 probands with autopsy-proven Alzheimer's disease did not support the hypothesis, advanced by Heston and co-workers, of a familial association between Alzheimer's disease, Down's syndrome and immunoproliferative disorders. However, there are difficulties of interpreting negative conclusions in this type of study, particularly those resulting from small sample size and the impossibility of tracing all relatives; only the data for immunoproliferative disorders are incompatible with the hypothesis, those for Down's syndrome being too few to be informative. The incidence of presenile dementia among the first-degree relatives of probands was raised, as in many previous studies, and was consistent with a simple polygenic model.
