Penile cutaneous horn is a clinical term that describes protruding hyperkeratosis, usually conical in shape, located on penile glans. Penile localization of this lesion, predominantly located on sun-exposed areas, is very rare. The association with malignancy on the penis makes proper identification of these lesions essential. We present a 45-year-old man with a cutaneous horn, 25 mm in size, l...

Spinal serotonergic pathways provide inhibitory and excitatory modulation of sensory, autonomic, and motor processing. After spinal cord injury (SCI), the acute inflammatory response is one process that damages descending pathways. Increases in serotonergic fiber density in spinal segments rostral and decreases caudal to the lesion have been observed previously and may contribute to neuropathic...

Fiddler crabs are highly sexually dimorphic. Males possess one small (minor) feeding claw and one greatly enlarged (major) claw; females possess two small claws. The major claw is used to attract mates and for burrow defense, but it is costly for the male to possess. We tested the hypothesis that the major claw also functions as a thermoregulatory structure, a function that would allow males to...

Pedal claw geometry can be used to predict behaviour in extant tetrapods and has frequently been used as an indicator of lifestyle and ecology in Mesozoic birds and other fossil reptiles, sometimes without acknowledgement of the caveat that data from other aspects of morphology and proportions also need to be considered. Variation in styles of measurement (both inner and outer claw curvature an...

it has been shown that the immunophilin ligands have the special advantage in spinal cord repair. in this study, the effects of cyclosporine a (csa) on functional recovery and histological outcome were evaluated following spinal cord injury in rats. after spinal cord hemisection in thirty six adult female sprague-dawley rats (200- 250 g), treatment groups received csa (2.5 mg/kg i.p.) at 15min ...

Keratoacanthoma is a benign skin tumour caused mainly by ultraviolet A radiation. It affects 150 out of every 100 000 people worldwide. The most common location the face, neck, and hands. usually middle-aged older men with fair phenotype. More importantly, this disease may be complication cutaneous cornification. described as circumscribed conical prominent hyperkeratotic lesion in literature, ...

A four-year-old Anatolian Shepherd bitch was brought to our clinic with an intermittent purulent-hemorrhagic vaginal discharge complaint no general symptoms for six months following the last parturition. There were signs of mass or lesion on wall during physical examination. Anechogenic uterine content, hyperechoic structures freely floating in lumen, and suspicious fetal tissue remnants detect...

A case of inflammatory pseudotumor is described, in which CT revealed a hyperdense intraventricular lesion with a trapped temporal horn, and MR imaging showed decreased T1 and markedly hypointense T2 signal with homogeneously intense enhancement. Radiologically and grossly the tumor resembled a meningioma; however, histologically it was composed purely of inflammatory, nonneoplastic components....
