Skull base chondrosarcomas are rare and account for approximately 0.15% of all intracranial tumors. Management of these tumors is challenging because of their potential to recur, and their proximity to vital structures such as major vessels and cranial nerves. We describe five patients with chondrosarcoma of the skull base who were managed at our institute between January 2002 and December

Development of low-cost disposable plasmonic substrates is vital for the applicability of plasmonic sensing. Such devices can be made using injection-molded templates to create plasmonic films. The elements of these plasmonic films are hybrid nanostructures composed of inverse and solid structures. Tuning the modal coupling between the two allows optimization of the optical properties for nanop...

Penetrating neck injuries are dangerous and deserve emergency treatment by virtue of the vital structures present underneath. There is a potential risk of unrecognized vascular injury and retained foreign bodies with their associated complications in these wounds. Therefore, an early diagnostic workup to localize the site of injury and an immediate neck exploration are important.

Nucleic acid secondary structure plays an important role in nucleic acid-nucleic acid recognition/hybridization processes, and is also a vital consideration in DNA nanotechnology. Although the influence of stable secondary structures on hybridization kinetics has been characterized, unstable secondary structures, which show positive ΔG° with self-folding, can also form, and their effects have n...

The Kosovo refugee crisis in the Macedonia in 1999 was unique in terms of its unprecedented magnitude against its short duration (sharp increase and sudden decrease in refugee population), its high visibility in the world media, and attention received by donors. In the late March 1999, after the launch of the NATO air campaign against the Federal Republic of Yugoslavia, refugees from Kosovo beg...

Proteins play diverse and vital roles in biology, which are dominated by their three-dimensional structures. The three-dimensional structure of a protein determines its functions and chemical properties. Protein secondary structures, including α-helices and β-sheets, are key components of the protein architecture. Molecular interactions, in particular hydrogen bonds, play significant roles in t...
