The effect of decompression on the structure of Methanococcus jannaschii, an extremely thermophilic deep-sea methanogen, was studied in a novel high-pressure, high-temperature bioreactor. The cell envelope of M. jannaschii appeared to rupture upon rapid decompression (ca. 1 s) from 260 atm of hyperbaric pressure. When decompression from 260 atm was performed over 5 min, the proportion of ruptur...

OBJECTIVE To evaluate changes in corneal astigmatism in patients undergoing orbital decompression surgery. METHODS This retrospective, non randomized comparative study involved 42 eyes from 21 patients with thyroid ophthalmopathy who underwent orbital decompression surgery between September 2011 and September 2014. The 42 eyes were divided into three groups: control (9 eyes), two-wall decompr...

INTRODUCTION Dysbaric osteonecrosis is a rare illness in professional divers and compressed-air workers. The correlation between dysbaric osteonecrosis and previous decompression sickness with osteoarthromuscular pain (type 1 decompression sickness) remains a controversial subject. The probability for ischemic lesions detected with MRI to turn into osteonecrosis after decompression sickness is ...

100 cases of extradural spinal compression comprising 74% of all cases of spinal  compression were included. ver-tebral and extravertebral compression occurred with  equal frequency.  1. most of tjhe cases occurred between 20-50 years of age, with no significant dif'fe'rerlce1s between various causes, except in vertebral hemangioma which tend o affect the younger age groups (10-20). males were ...

The authors present the endoscopic intranasal orbital decompression, one of the surgical techniques used for orbital decompression. It can be applied for various indications. The most common indications are: maxillo-facial trauma, orbital haemorrhage, subperiorbital abscess as the complication of sinusitis, optic neuropathy, thyroidassociated orbitopathy (Graves’ orbitopathy). The authors concl...

This report describes a rare clinical entity, thoracic myelopathy due to ossification of the posterior longitudinal ligament (OPLL), and its management. A 40-year-old woman presented with thoracic myelopathy due to OPLL, extending from T2-T9. We performed a posterior laminectomy and instrumented fusion. However, postoperative paraplegia occurred within 36 h post-surgery. Emergent anterior decom...

Graves' disease may occasionally result in significant proptosis that is either cosmetically unacceptable or causes visual loss. This has traditionally been managed surgically by external decompression of the orbital bony skeleton. Trans-nasal endoscopic orbital decompression is emerging as a new minimally-invasive technique, that avoids the need for cutaneous or gingival incisions. Decompressi...

Objective: To evaluate the clinical evidence and determine recommendations regarding theoptimal timing of decompression surgery following acute cervical spinal cord injury. Methods:A MEDLINE search of the English literature was performed using the search terms spinal cordinjury, SCI, quadriplegia and paraplegia, which were paired with the terms surgery,decompression, and tim...

Venous gas embolism (VGE) is reported with decompression to a decreased ambient pressure. With severe decompression, or in cases where an intracardiac septal defect (patent foramen ovale) exists, the venous bubbles can become arterialized and cause neurological decompression illness. Incidence rates of patent foramen ovale in the general population range from 25-34% and yet aviators, astronauts...

There is no doubt that data compression is very important in computer engineering. However, most lossless data compression and decompression algorithms are very hard to parallelize, because they use dictionaries updated sequentially. The main contribution of this paper is to present a new lossless data compression method that we call Light Loss-Less (LLL) compression. It is designed so that dec...
