Species-dependent responses of crop plants to polystyrene microplastics.

Only recently there has been a strong focus on the impacts of microplastics on terrestrial crop plants. This study aims to examine and compare the effects of microplastics on two monocotyledonous (barley, Hordeum vulgare and wheat, Triticum aestivum), and two dicotyledonous (carrot, Daucus carota and lettuce, Lactuca sativa) plant species through two complimentary experiments. First, we investigated the effects of low, medium, and high (10, 10, 10 particles per mL) concentrations of 500 nm polystyrene microplastics (PS-MPs) on seed germination and early development.

The Brain Pre-Metastatic Niche: Biological and Technical Advancements.

Metastasis, particularly brain metastasis, continues to puzzle researchers to this day, and exploring its molecular basis promises to break ground in developing new strategies for combatting this deadly cancer. In recent years, the research focus has shifted toward the earliest steps in the formation of metastasis. In this regard, significant progress has been achieved in understanding how the primary tumor affects distant organ sites before the arrival of tumor cells.

Validity and Reliability of a Commercial Fitness Watch for Measuring Running Dynamics.

Study Design Validity and reliability study. Background Providing feedback on running mechanics is a common intervention to decrease the risk of injury or to restore running after an injury. Commercially available devices are able to measure running dynamics, such as cadence, ground contact time (GCT), and vertical oscillation (VO), but there is limited evidence on the validity and reliability of these measures.

General surgery among long-term residents with and without active epilepsy at the Kork Epilepsy Centre - a prospective comparative one-year survey.

Background/aims: We prospectively assessed the frequency, type, severity and cause of treatment among the long-term residents of the Kork Epilepsy Centre in the year 2005.

Methods: All long-term residents were exclusively referred to the general surgeon practicing on the campus. Patients were divided into 2 groups comprising 285 patients with active epilepsy and 53 controls who either never had epileptic seizures or have remained seizure free for at least 4 years.

[Changes in blood coagulation in treatment with ALL-BFM-90 and NHL-BFM-90 protocols].

1. Treatment according to the ALL/NHL-BFM 90 protocol I (induction phase) caused multiple and severe coagulation changes in all 14 patients of our study. Glucocorticoids alone made Fibrinogen drop to 148 mg/dl, AT III and Protein C rise to 136% or even 179% respectively.
