Diagnostic and Predictive immunocytochemistry in Head Neck lesions.

The application of immunocytochemistry (ICC), as a diagnostic and predictive tool in the workup of head and neck lesions has followed the changes and progresses in the surgical pathology evaluation. The contribution of ICC has shown a significant role in the head and neck cytology, demonstrating as its contribution can support the diagnosis in many lesions. Furthermore, its role has been evolving as an important asjuvant tool in targeted therapies.

Cisplatin/Apo-Transferrin Adduct: X-ray Structure and Binding to the Transferrin Receptor 1.

Here, we report the X-ray structure of the adduct formed upon reaction of cisplatin, one of the most prescribed anticancer agents for the clinic treatment of solid tumors, with the apo-form of human serum transferrin (hTF). Two Pt binding sites were identified in both molecules of the adduct present in the crystal asymmetric unit: Pt binds close to the side chains of Met256 and Met499 at the N- and C-lobe, respectively. In the crystal structure, the cisplatin moiety bound to Met256 also interacts with Ser616 from a symmetry related molecule.

Solid stress estimations via intraoperative 3D navigation in patients with brain tumors.

Background: Physical forces exerted by expanding brain tumors - specifically the compressive stresses propagated through solid tissue structures - reduces brain perfusion and neurological function, but heretofore has not been directly measured in patients . Solid stress levels estimated from tumor growth patterns are negatively correlated with neurological performance in patients. We hypothesize that measurements of solid stress can be used to inform clinical management of brain tumors.

Interaction of VO-hydrazonates with lysozyme.

Vanadium compounds (VCs) exhibit a broad range of pharmacological properties, with their most significant medical applications being in the treatment of cancer and diabetes. The therapeutic effects and mode of action of VCs may be associated with their ability to bind proteins and, consequently, understanding the VC-protein interaction is of paramount importance. Among the promising VCs, the VO complex with the aroylhydrazone furan-2-carboxylic acid ((3-ethoxy-2-hydroxybenzylidene)hydrazide, hereafter denoted as VC1), deserves attention, since it exhibits cytotoxicity against various cancer cell lines, including HeLa.

CO Photoreduction Under Visible Light by TiO and Carbon Dots Derived from Pyrolized Bio-Oil.

Herein, we report a study on pyrolysis bio-oil upgrading from leather shaving waste to dope in situ titania (TiO) with carbon dots (cds). The cds doped TiO exhibits remarkable activity as photocatalyst under solar light for the direct conversion of carbon dioxide (CO) and water vapor (HO) to methane (CH). Morover, the catalytic activity also increased under uv radiation.
