Dermatophyties are diseases caused by keratinophilic fungi. We here report the case of a 8-year old vaccinated female child having extremely itchy vesicular-erosive lesions grouped in rosette-like pattern at the level of the tail of the left eyebrow (A), the nostrils, the extensor surfaces of the forearm and the upper part of the chest and back associated with hypochromic scars (B), without dig...

A central question in biology is how developmental mechanisms are altered to bring about morphological evolution. Drosophilids boast a remarkable diversity in eggshell-appendage number-from as few as one to as many as nine, depending on the species. Appendage patterning in Drosophila melanogaster is well characterized, inviting candidate-gene-based approaches that identify the developmental mec...

A 57 year-old male patient was admitted to our echocardiography laboratory to rule out thrombus in left atrium before electrical cardioversion of atrial fibrillation. Transoesophageal echocardiography (TEE) demonstrated in the bicaval view, the right atrial appendage measured 10 x 5 cm, area: 42 cm(2), volume: 229 mL (Figure, left). A quick injection of 15 cc of echo-contrast fluid (shaken sali...

Linear scleroderma (LS) is a localized form of scleroderma characterized by mononuclear cell infiltration and fibroblast proliferation. In the later stages of the disease, excessive collagen is deposited with concomitant skin and appendage atrophy. These symptoms suggest a breakdown of fibroblast cell function, and consequently, growth factors have been thought to play a role in the pathogenesi...

BACKGROUND Brown recluse spider bites are a serious medical problem in the southeastern United States. Although most bites are asymptomatic, envenomation can result in a constellation of systemic symptoms referred to as loxoscelism. Patients can also develop necrotic skin ulcers (necrotic arachnidism). These ulcers are often difficult to heal and can require skin grafting or amputation of the b...

Most of the chick body is covered with feathers, while the tarsometatarsus and the dorsal face of the digits form oblong overlapping scales (scuta) and the plantar face rounded nonoverlapping scales (reticula). Feathers and scuta are made of beta-keratins, while the epidermis of reticula and inter-appendage or apteria (nude regions) express a-keratins. These regional characteristics are determi...

Adaptor protein (AP) complexes bind to transmembrane proteins destined for internalisation and to membrane lipids, so linking cargo to the accessory internalisation machinery. This machinery interacts with the appendage domains of APs, which have platform and β-sandwich subdomains, forming the binding surfaces for interacting proteins. Proteins which interact with the subdomains do so via short...

OBJECTIVE To study the incidence of testicular and epididymal appendages in patients with cryptorchidism. MATERIALS AND METHODS We studied 65 patients with cryptorchidism, totalizing 83 testes and 40 patients who had prostate adenocarcinoma and hydrocele (control group), totalizing 55 testes. The following situations were analyzed: I) absence of testicular and epididymal appendages, II) prese...

Introduction: Due to nuclear interactions between the tissues and high-energy protons, the particles, including neutrons, positrons, and photons arise during proton therapy. This study aimed at investigating the dose distribution of proton and secondary particles, such as positrons, neutrons, and photons using the Monte Carlo method. Material and Methods:<...
