Hypoderma tarandi causes myiasis in reindeer and caribou (Rangifer tarandus spp.) in most northern hemisphere regions where these animals live. We report a series of 39 human myiasis cases caused by H. tarandi in Norway from 2011 to 2016. Thirty-two were residents of Finnmark, the northernmost county of Norway, one a visitor to Finnmark, and six lived in other counties of Norway where reindeer live. Clinical manifestations involved migratory dermal swellings of the face and head, enlargement of regional lymph nodes, and periorbital oedema, with or without eosinophilia...

Ebstein anomaly is a rare congenital heart disease that has been described in domestic dogs, a meerkat, a pygmy goat, and a lion. An 11-mo-old Tsushima leopard cat presented to Osaka Prefecture University Veterinary Hospital for diagnosis and treatment of right-sided congestive heart failure. Echocardiography showed a dilated right atrium and ventricle with an enlarged tricuspid valve annulus and apical displacement of the tricuspid valve leaflets. The cat was diagnosed with Ebstein anomaly. To the best of our knowledge, this is the first report of this type of congenital heart disease in a Tsushima leopard cat...

A 14-yr- old, male harbor seal ( Phoca vitulina ) presented with depression, anorexia, and weight loss. Clinical examination revealed no specific abnormalities. Diagnostic imaging displayed an enlarged mass in the dorso-cranial abdomen. The animal was euthanized due to progressive worsening of symptoms. Grossly, severe emaciation and a massive enlargement of one mesenteric lymph node were found. Microscopically, a neoplastic round cell population with morphologic characteristics of mature lymphocytes infiltrated the mesenteric lymph node as well as the jejunal mucosa and exhibited a marked invasion of the mucosal epithelial layer...

Fat embolism is an incidental finding in cases of long bone fractures or other trauma, but it is also associated with liposuction and autologous fat transfer, a procedure where fat from liposuction is injected back into the same patient's face, breast, buttocks or penis. We here present a case of sudden death by fat embolism in a healthy young male, caused by a simple penis enlargement procedure, in which fat was injected into the penis shaft. We suggest that the risk of fat embolization might be higher when pretraumatized tissue is subjected to fat injection, like in this case, where a penis elongation was performed before the fat injection...

Multicystic renal dysplasia (MCRD) is the most common cause of abnormally enlarged kidney, diagnosed on antenatal ultrasound examination. It is an abnormality of the embryonic development in which the renal parenchyma is substituted by nonfunctioning renal tissue made up of cysts which do not communicate with each other. Vesicoureteric reflux (VUR), pelviureteric junction obstruction, vesicoureteric junction obstruction, and ureterocele are the most commonly seen abnormalities in contralateral kidney. Here, we report a case of prenatal diagnosis of unilateral MCRD with VUR in contralateral kidney...

Jean-Pierre Gratia
The exact meaning of sexual reproduction and the precise evolutionary period at which recombination first took place remains the subject of intense debates. Despite some unity in biochemical organisation of genetic recombination, a plethora of mechanisms are found to exist in microbes and their viruses. Some routes used by viruses bypass barriers to genetic heterology and provide bacteria with genes conferring a selective advantage, and some contribute to genome enlargement. The present review aims at highlighting the diversity of such mechanisms with a particular focus on spontaneous zygogenesis (or Z-mating)...

Metabolic derangements are a clinically significant complication of major trauma (e.g., burn injury) and include various aspects of metabolism, such as insulin resistance, muscle wasting, mitochondrial dysfunction and hyperlactatemia. Nonetheless, the molecular pathogenesis and the relation between these diverse metabolic alterations are poorly understood. We have previously shown that burn increases farnesyltransferase (FTase) expression and protein farnesylation and that FTase inhibitor (FTI) prevents burn-induced hyperlactatemia, insulin resistance, and increased proteolysis in mouse skeletal muscle...

The patient was a male infant with an antenatal diagnosis of huge intraabdominal mass. Prenatal ultrasound at 35 weeks gestation revealed a markedly enlarged cystic mass in the lower abdomen. After birth at 38 weeks, the infant was allowed to void spontaneously and passed meconium. Ultrasonography showed an enlarged bladder with wall thickness of 2.9 mm and no hydronephrosis. Voiding cystourethrograms showed no evidence of vesicoureteral reflex and posterior urethral valve. The post-void residuals were 15 mL at 11 days of life, 5 mL at 1 month and 0 mL at 5 months...

Carbon materials promise a revolution in optoelectronics, medical applications, and sensing provided that their morphology can be controlled down to the nanometer scale. Nanoporous materials are particularly appealing as they offer a drastically enlarged interfacial area compared to the corresponding planar materials. Entire fields such as organic solar cells, catalysis or sensing may profit from an enlarged interface and facilitated molecular interaction between a carbon material and the environment. Nanoporous fullerene thin films obtained by the deposition of suspended nano-clusters of fullerene were already reported but suffered from the limitation of the size of these particles to over 100 nm...

The unique selectivity of enzymes, along with their remarkable catalytic activity, constitute powerful tools for transforming renewable feedstock and also for adding value to an array of building blocks and monomers produced by the emerging bio-based chemistry sector. Although some relevant biotransformations run at the ton scale demonstrate the success of biocatalysis in industry, there is still a huge untapped potential of catalytic activities available for targeted valorization of new raw materials, such as waste streams and CO2...

Macroglossia is classified as true macroglossia, which exhibits abnormal histology with clinical findings, and relative macroglossia, in which normal histology does not correlate with pathologic enlargement. This report describes an atypical case of morbidity with massive macroglossia secondary to myxedema; the macroglossia enlarged over a 3-month period before being presented to the Department of Oral and Maxillofacial Surgery, University of Texas Health Sciences Center at Houston (Houston, TX). Substantial enlargement of the tongue (16 cm long × 10 cm wide) was first attributed to angioedema, which was refractory to the discontinuation of lisinopril and a C1 esterase inhibitor...
