Abstract
We report a 75-year-old male patient with parkinsonism and head drop caused by isolated myasthenic weakness of the neck extensor muscles. Our case is the second report of isolated head drop as a presenting symptom of myasthenia gravis in a patient with parkinsonism....

We report two patients who were treated acutely for this condition. Both presented with weakness in the upper limbs and paraspinal cervical musculature after a fracture of C2. Despite improvement in the strength of the upper limbs, the paraspinal muscle weakness persisted in both patients. One ultim...

Abstract
South Africa is home to 9 vulture species, of which 7 are endangered. While the cause of the population declines remains largely speculative, a vast amount of effort has been dedicated towards the protection of populations by ensuring sustainable and safe food sources for the various colonies. Limite...

Abstract
We have generated a zebrafish line carrying a stop mutation in the kinase domain of the Tie-2 receptor. Mutant embryos lack Tie-2 protein, but do not display any defect in heart and vessel development. Simultaneous loss of Tie-1 and Tie-2, however, leads to a cardiac phenotype. Our study shows that...

Under physiological conditions, neuronal activity is tightly coupled to hemodynamics of the surrounding microvessels. Conversely, most brain diseases are associated with a disturbance in neurovascular coupling. Measuring the hemodynamic response of the microvascular network to neuronal stimulation i...

We detected several long chain aliphatic alcohols ranging from C18-C32 in honey bees and the level of these alcohols varied in each body segment. C18:0Alc and C20:0Alc are more pronounced in the head, whereas C22:0Alc to C32Alc are abundant in the abdomen. One of the cDNAs coding for a fatty acyl-Co...

Abstract
We provide multiple lines of evidence establishing PHF8 as the first mono-methyl histone H4 lysine 20 (H4K20me1) demethylase, with additional activities towards histone H3K9me1 and me2. PHF8 is located around the transcription start sites (TSS) of approximately 7,000 RefSeq genes and in gene bodies...

The head should be kept in as near a neutral position as possible because the overlap increased by head rotation in both sides. In addition, the right IJV should be preferred because of less CA overlap and more lateral positioning than the left.

A human being born without heart and head, i.e., the acardius/acranius malformation, has been described since antiquity. Superstition and fear made it a mystical disorder, a sign of God's wrath. The inquisition ruled that acranic infants should not be baptized and located the soul in the brain. Acar...
