Fish and amphibians have pigment cells that generate colorful skins important for signaling, camouflage, thermoregulation and protection against ultraviolet radiation (UVR). However, many animals also have pigment cells inside their bodies, on their internal organs and membranes. In contrast to external pigmentation, internal pigmentation is remarkably little studied and its function is not wel...

IDS are becoming the logical next step for many organizations after deploying firewall technology at the network perimeter. IDS can offer protection from external users and internal attackers, where traffic doesn't go past the firewall at all. However, the following points are very important to keep in mind. 1. Strong identification and authentication: An IDS uses very good signature analysis m...

In this paper we discuss the impact the use of IPv6 has on remote penetration testing of servers and web applications. Several modifications to the penetration testing process are proposed to accommodate IPv6. Among these modifications are ways of performing fragmentation attacks, host discovery and brute-force protection. We also propose new checks for IPv6-specific vulnerabilities, such as by...

The skin is the largest bodyorgan and in the normal state, forms a complete anatomic and physiologic barrier between the animal and its environment While providing protection against a variety of noxious physical, chemical, and microbiological agents, it serves as a sensory organ which is in constant communicationwith internal body systemsand reflects pathological processes that may be either p...

A 72-year-old female presented with episodes of epistaxis. Neuroimaging demonstrated a large prolactinoma totally enclosing a large intracavernous aneurysm of the internal carotid artery. Adjacent bony structures were eroded and destroyed by tumor invasion and extension. Rupture of the intratumoral aneurysm caused fatal epistaxis rather than subarachnoid hemorrhage before surgery. Intratumoral ...

A 78-year-old man, who had previously undergone coronary artery bypass graft surgery, was admitted to our department for treatment of a distal aortic arch aneurysm. A total aortic arch replacement with a patent left internal thoracic artery (LITA) graft was successfully performed without cardiac ischemic or neurological complications. Use of retrograde cardioplegia with intermittent pressure-au...

Routine internal dose exposures are typically (in the UK nuclear industry) less than external dose exposures: however, the costs of internal dosimetry monitoring programmes can be significantly greater than those for external dosimetry. For this reason decisions on when to apply routine monitoring programmes, and the nature of these programmes, can be more critical than for external dosimetry p...

Compared to internal laryngeal trauma caused by endolaryngeal procedures, trauma to the larynx caused by external forces is relatively rare. It has been incidence of 1 in every 22,900 emergency room visits. Rapid evaluation and protection of the airway are critical. A history of a cervical trauma with signs of hoarseness, difficulty breathing and pain should always alert the emergency physician...
