Zusammenfassung Ichthyosen sind hereditäre Verhornungsstörungen, die isoliert/nichtsyndromal oder mit assoziierten Erkrankungen an inneren Organen (syndromal) auftreten und bei Neugeborenen zu lebensbedrohlichen Komplikationen führen können. Die Identifizierung der genetischen Ursachen hat zum Verständnis der molekularen Mechanismen, aber auch zur Reklassifizierung geführt. Auch die pathologischen Veränderungen der Hautbiopsien wurden genauer charakterisiert. Dabei konnten bestimmte...

Zusammenfassung Der Mamillen-Areola-Komplex ist Ausgangspunkt verschiedener morphologisch eigenständiger Tumoren und tumorartiger Veränderungen, die sich von den besonderen Strukturen der Mamille, insbesondere den intramamillären Milchgängen, den Anhangsgebilden und dem intramamillären Stroma ableiten lassen. Im Vordergrund stehen dabei epitheliale Tumoren gutartigen Verhaltens wie das Mamillenadenom und der syringomatöse Tumor der Mamille. Seltener sind benigne mesenchymale Tumoren...

J Neurol Surg B Skull BaseDOI: 10.1055/s-0040-1712462 Objectives Local failure of incompletely resected vestibular schwannoma (VS) following salvage stereotactic radiosurgery (SRS) using standard doses of 12 to 13 Gy is common. We hypothesized that dose-escalated SRS, corrected for biologically effective dose, would have superior local control of high-grade VS progressing after subtotal or near-total resection compared with standard-dose SRS. Design Retrospective cohort study....

J Neurol Surg B Skull BaseDOI: 10.1055/s-0040-1712180 Objective Data regarding the surgical advantages and anatomic constraints of a hearing-preserving endoscopic-assisted retrolabyrinthine approach to the IAC are scarce. This study aimed to define the minimum amount of retrosigmoid dural exposure necessary for endoscopic exposure of the IAC and the surgical freedom of motion afforded by this approach. Methods Presigmoid retrolabyrinthine approaches were performed on fresh...

Abstract Angiotensin-II (Ang-II) receptor plays a role in allergic airway inflammation; however, the underlying mechanism and role of macrophages need better understanding. In the present study, angiotensin-II infusion (1 μg/kg/min) in ovalbumin-induced airway inflammation mice model significantly decreased immune cell infiltration, goblet cell hyperplasia, and eosinophil numbers in lungs. Ang-II infusion increased M1 and decreased M2 macrophage...

Abstract Apigenin, a flavonoid found in many plants, has various biological properties. We aimed to investigate the anti-inflammatory and anti-oxidative activity of apigenin against carbon tetrachloride (CCl4)-induced acute liver injury in mice and hydrogen peroxide (H2O2)-induced oxidative stress in HepG2 cells and possible mechanism. In vivo, apigenin significantly reduced alanine aminotransferase (ALT) and aspartate aminotransferase...

Abstract Octopus cells in the ventral cochlear nucleus (VCN) have been difficult to study because of the very features that distinguish them from other VCN neurons. We performed in vivo recordings in cats on well-isolated units, some of which were intracellularly labeled and histologically reconstructed. We found that responses to low-frequency tones with frequencies < 1 kHz reveal higher levels of neural synchrony and entrainment to the stimulus than the auditory nerve. In...

Abstract Purpose Adversity in early life can induce metabolic defects in exposure to stress in adulthood. Therefore, the exploration of involving mechanisms can be helpful in the treatment of metabolic disorders. So, the present study was conducted in terms of exploring the effects of interaction between early postnatal stress and young adulthood psychological stress on insulin secretion and pancreatic GLUT-2 levels in male rats. ...

Laryngeal botulinum toxin injection is an important treatment modality for spasmodic dysphonia and other laryngeal disorders. We sought to compare usage patterns of laryngeal botulinum toxin injections for voice disorders and to identify and quantify inefficiencies and barriers in providing this treatment. A 26 item survey was written and approved for distribution by the American Academy of Otolaryngology-Head and Neck Surgery and the National Spasmodic Dysphonia Association. It was distributed to...

The Space Shuttle orbiter lifted off for the last time in July 2011. (NASA/Bill Ingalls/)If all goes according to plan tomorrow, two NASA astronauts will blast off on a SpaceX Falcon 9 rocket from Florida, bound for the International Space Station (ISS). It will be the first crewed launch from US soil since 2011, when the Space Shuttle orbiter made its last flight.When the Shuttle made its debut on the Kennedy Space Center launchpad in 1981, it had two astronauts on board. Up to that point, NASA...

You too can have secret powers. (Amazon/)Multi-tools feel like secret weapons; they’re a practical solution to all sorts of problems that pop up during everyday life. While you probably won’t (we hope) have to use one to escape from a locked room, or cut the wires of a covert device that has your highly classified chemistry lab under surveillance, the possibility of MacGyver-ing your way out of a scrape is part of the allure. These cleverly-designed standouts will help you feel ready to handle whatever...

Time to create. (Jakub Dziubak via Unsplash/)Much can be said about the effects of technology on popular music over the years, but few inventions were as pivotal to the progression of modern music as the introduction of the synthesizer. This computerized, electronic instrument made its way into music from every corner of the globe and allowed widespread access to never-before-heard instrumental sounds that have since become touchstones of pop culture. In recent years, new synthesizers have taken...

A stunningly simple solution. (Nadine Shaabana via Unsplash/)Frequent online video meetings are a side-effect of working from home that not everyone loves, and can be downright exhausting. On top of the challenges of getting a word in without being able to make direct eye contact, most of us are constantly distracted by our own faces staring back at us. You can’t just time your meetings for when you can sit in an ethereal beam of diffused sunlight, but there’s no denying the harsh realities of too-little...

Monty Hall hosted about 4,500 episodes of the TV game show Let's Make a Deal over two decades. (Brian Klutch/)We know you are bored at home right now—we are too. Here are some puzzles and brainteasers to challenge your family and friends with, either in person or over video chat. From the 1960s to the ’80s, Monty Hall, host of Let’s Make a Deal, presented this puzzle: Players had to choose among three doors. Two hid a gag gift (like a goat); the third, a prize (say, a car). Simple, but the game...
