Robotics-Driven Manufacturing of Cartilaginous Microtissues for Skeletal Tissue Engineering Applications.

Automated technologies are attractive for enhancing the robust manufacturing of tissue-engineered products for clinical translation. In this work, we present an automation strategy using a robotics platform for media changes, and imaging of cartilaginous microtissues cultured in static microwell platforms. We use an automated image analysis pipeline to extract microtissue displacements and morphological features as noninvasive quality attributes.

Engineering bone-forming biohybrid sheets through the integration of melt electrowritten membranes and cartilaginous microspheroids.

Bone fractures are one of the most common traumatic large-organ injuries and although many fractures can heal on their own, 2-12% of fractures are slow healing or do not heal (non-unions). Autologous grafts are currently used for treatment of non-unions but are associated with limited healthy bone tissue. Tissue engineered cell-based products have promise for an alternative treatment method.

Vicia faba Hypersensitivity and ASA Intolerance in a Farmer: A Case Report.

The IgE-mediated allergic reactions to food are caused, generally, by ingestion. However, they can be rarely induced by exposure to airborne food particles through the handling or the cooking. Vicia faba is a vegetable which belongs to Legumes or Fabaceae family, Fabales order.

Biological and genetic evolution of HIV type 1 in two siblings with different patterns of disease progression.

To investigate the immunological and virological factors that may lead to different patterns of disease progression characteristic of HIV-1-infected children, two HIV-1-infected siblings, a slow and a fast progressor, were followed prospectively before the onset of highly active antiretroviral therapy. Viral coreceptor usage, including the use of CCR5/CXCR4 chimeric receptors, macrophage tropism, and sensitivity to the CC-chemokine RANTES, has been studied. An autologous and heterologous neutralizing antibody response has been documented using peripheral blood mononuclear cells- and GHOST(3) cell line-based assays.

Potential role of cholinesterases in the invasive capacity of the freshwater bivalve, Anodonta woodiana (Bivalvia: Unionacea): a comparative study with the indigenous species of the genus, Anodonta sp.

To address the potential role of cholinesterase enzymes in the invasive capacity of species, the present study investigated ChE activity in the invasive freshwater bivalve Anodonta woodiana (Lea, 1834) comparing it with that of the indigenous species, Anodonta sp. (Linnaeus, 1758). The invasive capacity of pests has often been linked to their ecological plasticity and high intrinsic genetic variability; however the role played by molecular and cellular mechanisms, generally known as an organism's response to pollution, is unclear.

Prognostic value of the stromal cell-derived factor 1 3'A mutation in pediatric human immunodeficiency virus type 1 infection.

A mutation of the stromal cell-derived factor 1 gene (SDF-1 3'A) was shown to protect adults exposed to human immunodeficiency virus type 1 (HIV-1) from infection and to affect HIV disease progression in adults. The presence of this mutation in HIV-1-infected Kenyan children did not predict mother-to-child virus transmission. The SDF-1 3'A polymorphism was studied in 256 HIV-1-infected, 118 HIV-1-exposed but uninfected, and 170 unexposed and uninfected children of Italian origin, and the frequency of SDF-1 3'A heterozygosity and homozygosity in each of the 3 groups was similar.
