A 41-year-old male presented with penetrating carotid artery injury after being stabbed in the left neck with a knife. He had profuse bleeding from the wound and was in hemorrhagic shock. No neuroimaging evaluation was possible, so emergent surgery was begun with continuous manual compression of the left neck. Graft reconstruction of the injured carotid artery was performed. He recovered well w...

An elite level fencer sustained a penetrating wound to the upper arm after his opponent's blade broke. Standard care for a deep puncture wound was given but it was some time before the athlete presented symptoms of a pneumothorax, which was confirmed by radiograph. Although resolution of this case was unremarkable, the possibility of penetrating thoracic injury, even when the point of entry is ...

Orbital penetrating injuries may cause significant harm to the optic nerves and eyeball as well as to the brain and cerebral vessels. Management of orbital foreign bodies should include prompt recognition of the extent of the injury, broad-spectrum parenteral antibiotics, tetanus prophylaxis, anticonvulsant medication and early surgical intervention under direct vision to remove the foreign bod...

Hepatic arterial injury secondary to both blunt and penetrating traumas is well documented in the literature by case reports and articles regarding management. Penetrating injuries to the hepatic arteries are more common than injuries from blunt trauma. Hepatic arterial injuries secondary to blunt traumas are often associated with injuries to other vital organs or vascular structures, resulting...

trauma continues to be the most frequent cause of death in the first four decades of life that is a main public health problem in some countries. we perform an epidemiological study of penetrating abdominal trauma (pat). we describe epidemiological of patients in pat. in a cross-sectional study we evaluated epidemiological pat admitted to emergency department in six general hospitals in tehran....

purpose: to report a case of recurrent keratoconus after penetrating keratoplasty (pk). patient and findings: a 31-year-old male patient who had undergone pk in his right eye for keratoconus 10 years ago presented with gradually decreased vision in the right eye. clinical, topographic, and histopathologic features of the cornea including irregular myopic astigmatism, central and paracentral cor...

Cell-penetrating peptides provide a highly promising strategy for intracellular drug delivery. One relevant clinical application of cell-penetrating peptides is cancer therapeutics. Peptide based delivery could increase the uptake of drugs in tumor cells and thereby increase the efficacy of the treatment, either of conventional small molecular drugs or oligonucleotide based therapeutics. This r...

Abstract Time fluctuations of groundwater flux are known to affect solute transport and thus the width penetration seawater intrusion. Yet, most theoretical laboratory studies mixed‐convective processes accompanying intrusion assume constant extraction rates, even though real‐world pumping is usually intermittent. In this study, dynamic changes an experimental saltwater wedge caused by intermit...

It is well known that artificial light at night alters the natural patterns of in space and time, which interrupts a variety physiological processes individuals, altering their life history behavioral adjustments. However, much less about effect on fitness. We tested hypothesis planktonic animals, such as Daphnia spp., are able to correctly assess intensity- spectrum-dependent-mortality risk du...

Penetrating craniocerebral trauma is an injury in which a projectile violates the skull but does not exit. The significance of penetrating injuries to the head depends largely on the circumstances of the injury, the velocity of impact, and attributes of the projectile. While most penetrating head injuries are caused by firearms, lower-velocity mechanisms of penetrating brain injury present uniq...
