The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the ...

Synopsis In recent years there has been growing interest in uncovering evolutionary and lifetime factors that may contribute to the domestic dog’s (Canis lupus familiaris) success anthropogenic environments. The readiness with which dogs form social attachments, their hyper-social focus, flexibility have all areas of investigation. Prior research demonstrated many pet infant-caregiver type atta...

519 Biologically relevant information in acoustic signals often is present in its temporal structure. For example, the temporal relationships of particular acoustic elements are important for identifying human speech signals1, the proximity of a target in bat sonar2, songs in birds3, and calls in anuran amphibians4 (frogs and toads) and crickets5. In the sensory periphery, these signals are rep...

Usually she discovers herself inadequate to meet life as independently as she would like. She finds also that the consequences of independence are somewhat staggering.

MOTIVATION We present a new probabilistic model of the evolution of RNA-, DNA-, or protein-like sequences and a software tool, Rose, that implements this model. Guided by an evolutionary tree, a family of related sequences is created from a common ancestor sequence by insertion, deletion and substitution of characters. During this artificial evolutionary process, the 'true' history is logged an...
