Kinetic pulse-labeling of aflatoxin pathway compounds was carried out in Aspergillus parasiticus, beginning with radioactive acetate. Norsolorinic acid, averufin, versicolorin A, and sterigmatocystin (all known as compounds which can be incorporated into the aflatoxin molecule) were radiotraced to follow their order of appearance. Aflatoxin species B1, B2, G1, and G2 were included. Norsolorinic...

Homeostatic regulation of spine number in mature hippocampal neurons results in more dendritic spines when synaptic transmission is blocked, providing a mechanism to compensate for diminished synaptic input. It is unsettled whether blockade of synaptic transmission also elevates spine number during development. To address this question, synaptic transmission was blocked in rat hippocampal slice...

BACKGROUND One of the basic principles in the primary survey of a trauma patient is immobilisation of the cervical spine till cleared of any injury. Lateral cervical spine radiograph is one of the important initial radiographic assessments. More than often additional radiographs like the Swimmer's view are necessary for adequate visualisation of the cervical spine. How good is the Swimmer's vie...

spinal traumatic injuries are the major damage which is associated with morbidity and mortality rates. in this study the epidemiological characteristics of spinal trauma and their outcome were investigated. in this cross sectional study, trauma patients who admitted to imam reza hospital were included. their information such as age, sex, type of injury, severity of injury and site of injury was...

background: one of the important sites for extrapulmonary tb involvement is the skeleton. tuberculous spondylitis (pott’s disease) comprises 50-70% of the skeletal tuberculosis. methods: in this case series study, we prospectively investigated the result of anterior surgery alone (anterior debridement, fusion and instrumentation) in the patients with spinal tuberculosis. the patients with immat...

Pathologies of spine like trauma, infection, malignancy or congenital problems can cause disturbed structural integrity causing deformity and displacement spine. This causes compression damage on spinal cord roots, which the is supposed to protect. In such situations, needs be decompressed, realigned fused in that position, so further injury prevented. Spinal fusion a natural process healing bo...

Traditional techniques for visualizing anatomical structures are based on planar sections from volume images, like images obtained by computed tomography (CT) or magnetic resonance imaging (MRI). However, planar slices taken in the coordinate system of the 3D image often do not provide sufficient or qualitative enough diagnostic information. The reason is that because planar slices do not follo...

In 1992, I was hired by the State of Oregon as an expert witness in a trial of four chiropractors who had been accused of using a "Toftness-like device" in their practices. The "Toftness Radiation Detector" was an appliance designed by a chiropractor for diagnosing ailments. It consisted of a metal cylinder shaped somewhat like a thick soup can. At one end was a lens; at the other was a smooth ...
