Irregular, concentric zones of increased signal on T2-weighted cranial MR imaging studies may strongly suggest Balo concentric sclerosis (BCS), a rare but recognized variant of multiple sclerosis. Differentiating BCS from multiple sclerosis or neoplasm can be difficult clinically, but MR imaging findings noted in this case may be pathognomonic.

The Achilles tendon is built up mainly of collagen and it contains minute amounts of ground substances and cell materials. Opinions about its content of polysaccharides vary considerably. The ground substance of connective tissue is rich in acid mucopolysaccharides and Meyer (1957) has isolated the chondroitin sulphates from Achilles tendon. Besides the acid mucopolysaccharides the presence of ...

Bdellovibrio-and-like organisms (BALOs) are widespread obligatory predators of other Gram-negative bacteria. Their detection by culture-dependent methods is complicated as their replication is totally dependent upon the availability of an appropriate prey. Because BALOs do not form numerically dominant groups within microbial communities, non-specific culture-independent tools also generally fa...

Osmanlı Devleti’nin son dönemine Batılılaşma politikası damgasını vurdu. Bâbıâli, Tanzimat Fermanı ile Batı’ya yöneldikten sonra kulüp, birahane, tiyatro, müzik toplulukları ve balo gibi Avrupa örneği zevk eğlenceler yaygınlaşmaya başladı. Galata, Pera Beyoğlu’nda yaşayan yabancılar, Türklerin bu eğlence kültürüne adapte sürecini hızlandırdı. Batılılaşmayı sağlama adına seçkini de Batı kültür f...

T his Letter to the Editor concerns a recent article published in mBio (1). I am offering my comments on this article in the spirit of the correct interpretation of scientific data. My areas of expertise are in electron microscopy and in prokaryotic predators known as Bdellovibrio and Bdellovibrio-like organisms (BALOs). I have a recent article in the International Journal of Systematic and Evo...
