Amended Vegetation Filters as Nature-Based Solutions for the Treatment of Pharmaceuticals: Infiltration Experiments Coupled to Reactive Transport Modelling.

In small populations and scattered communities, wastewater treatment through vegetation filters (VFs), a nature-based solution, has proved to be feasible, especially for nutrient and organic matter removal. However, the presence of pharmaceuticals in wastewater and their potential to infiltrate through the vadose zone and reach groundwater is a drawback in the evaluation of VF performances. Soil amended with readily labile carbon sources, such as woodchips, enhances microbial activity and sorption processes, which could improve pharmaceutical attenuation in VFs.

[Incidence of hepatitis C infection among donors of femur heads to the tissue bank].

Living donors of femoral heads belong to a highly specific group in terms of age and pathological characteristic, forming the core of the group who supply many tissue banks with spongy bone, to cover the needs of several specialties in the field of repair and corrective surgery. Analysis for the presence of the hepatitis C virus in this population was conducted as a part of quality control programs, while habitual blood donors from the same geographical location were used as the control group. Although the comparison of results could give rise to erroneous interpretations, due to the lack of qualitative fit between the groups, a much higher incidence of infection by VHC was found in the donors of spongy bone than was the case for blood donors (3.

bcl-2 expression in plasma cells from neoplastic gammopathies and reactive plasmacytosis: a comparative study.

Background And Objective: bcl-2 oncoprotein plays a major physiological role in hemopoietic and non-hemopoietic cells by preventing apoptosis (programmed cell death). Disregulation of this process may be important in oncogenesis and the response to treatment of patients with different hematological malignancies. We have investigated the levels of bcl-2 expression in plasma cells from patients with reactive plasmacytosis (RP), monoclonal gammopathy of unknown significance (MGUS) and multiple myeloma (MM), correlating the bcl-2 expression and clinico-biological features in MM patients.
