hepatomas have demonstrated that a spectrum of such tumors exists with varying degrees of change from the parent hepatocyte (26—30). Such hepatocarcinomas as the Morris 5123 (18) and Reuber H-35 (34), for instance, resemble the parent tissue to a marked degree both morphologically and biochemically (27), and thus fall in the category termed “minimaldeviation hepatomas― by Potter (31). On ...

The majority of studies into visually induced motion sickness (VIMS) either use complex motion scenarios or are limited to single-axis motion. This study compared VIMS during singleand dual-axis motion. Twelve participants were exposed to (i) oscillating roll motion, (ii) linear motion in the anterior-posterior axis, and (iii) spiral motion, i.e. the summed direction of both of these flow vecto...

The effect of intracerebroventricular (icv) injections of beta-amyloid peptide fragments Abeta[15-25], Abeta[25-35], and Abeta[35-25] were examined on synaptic transmission and long-term potentiation (LTP) in the hippocampal CA1 region in vivo. Rats were anesthetized using urethan, and changes in synaptic efficacy were determined from the slope of the excitatory postsynaptic potential (EPSP). B...

Freir, Darragh B., Christian Holscher, and Caroline E. Herron. Blockade of long-term potentiation by b-amyloid peptides in the CA1 region of the rat hippocampus in vivo. J Neurophysiol 85: 708–713, 2001. The effect of intracerebroventricular (icv) injections of b-amyloid peptide fragments Ab[15–25], Ab[25–35], and Ab[35–25] were examined on synaptic transmission and long-term potentiation (LTP)...

MNDO semi-empirical SCF MO calculations are used to study the pyramidal nitrogen atom inversion and configurational equilibria in the title compounds.

OBJECTIVE Considering that epidemiological studies show that suicide rates in many countries are highest in the spring when vitamin D status is lowest, and that low vitamin D status can affect brain function, we sought to evaluate if a low level of 25-hydroxyvitamin D [25(OH)D] could be a predisposing factor for suicide. METHOD We conducted a prospective, nested, case-control study using seru...

The most widely used indicator of vitamin D status is the measurement of 25-hydroxyvitamin D [25(OH)D] in either serum or plasma. Several studies have reported discrepancies between the results of assays used to measure 25(OH)D, however, which calls into question the ability of 25(OH)D assays to reflect accurately the vitamin D status of individuals. The National Institute of Standards and Tech...

CONCLUSION: MIDAS is suboptimal to describe disability in our patients due to a mean preoperative score of 102, as severe disability is defined as 21+. PSEQ successfully demonstrates extent of disability in this patient population and puts migraine surgery in perspective to other known pain treatments. It further evaluates functional outcome, rather than just improvement in symptoms. This signi...
