Exploring the relationship between phenotype and performance in an ecological and evolutionary context is crucial to understanding the adaptive nature of phenotypic traits. Despite their ubiquity in vertebrates, few studies have examined the functional and ecological significance of claw morphologies. Here we examine the adhesive toepad and claw system of Anolis lizards. Claw characters are sig...

The aim of the presented study was to estimate the influence of the traits of hoof measurement in dairy cows on claw disorders, lameness, and locomotion scores were determined. Data on claw health and measurement trait of claws were collected from 68 primiparous cows housed in tie stalls and from 76 primiparous cows housed in free stalls. Data were collected during professional claw trimming. T...

Abstract Background Mullerian duct anomalies are a broad spectrum of congenital the female genital tract presenting with variable symptoms like infertility, amenorrhoea, dysmenorrhea, pelvic endometriosis, and poor obstetric outcomes. Unicornuate uterus or hemiuterus occurs as result abnormal formation failure contralateral part. Case presentation We present rare case report functional non-comm...

Detailed knowledge about claw formation and growth rate is a prerequisite for the interpretation of avian claw stable isotopes, as is commonly done with feather stable isotopes to e.g. infer habitat use, dietary specialisations, and spatial occurrence. In this study, we provide basic information about claw formation and empirical evidence about the time scale of archiving isotopic information t...

Penetrating limb injuries are common and usually heal without long-lasting effects, even when nerves are cut. However, rare nerve-injury patients develop prolonged and disabling chronic pain (neuralgia). When pain severity is disproportionate to severity of the inciting injury, physicians and insurers may suspect exaggeration and limit care or benefits, although the nature of the relationship b...

Cutaneous horns are usually found on chronic sun-damaged skin. A cutaneous horn is a rare tumour, often conical, circumscribed, and composed of dead keratin usually derived from base keratinocytes. It occurs mainly in association with underlying benign, premalignant, and malignant cutaneous diseases. The commonest malignancy is squamous cell carcinoma. Thus, to accurately ascertain the nature o...

Background: Strumpel disease and dystonia are inherited disorders with the clinical picture of spastic paraparesis and hyperkinesis respectively. We present a case of a patient born from parents with these diseases who developed neurologic phenomena uncharacteristic for the classical clinical picture of his parents’ disorders. Case report: Patient V., 12, born from his father with generalized d...

Merkel cell carcinoma (MCC) is a rare cutaneous neuroendocrine malignancy, which usually presents as an asymptomatic, rapidly growing, firm nodule on sun-damaged skin. We present a 93-year-old female who presented with a "cutaneous horn" on the face. On excision, histologic examination revealed a combined squamous cell carcinoma in situ with underlying MCC. Merkel cell polyomavirus immunohistoc...
