a rare case of squamous cell carcinoma ex pleomorphic adenoma in maxillary sinus is presented. the patient is a 50-year-old woman presenting with a slow-progressive swelling in left side of her face that she has noticed 2 years earlier. the lesion was not painful and caused asymmetry and mild exophthalmos. microscopic examination revealed that the tumor was composed of two components partly of ...

It is shown how grand unification can occur in models which are partly supersymmetric. The particle states which are composite do not contribute to the running of gauge couplings above the compositeness scale, while the elementary states contribute the usual large logarithmns. This introduces a new differential running contribution to the gauge couplings from partly composite SU(5) matter multi...

Newborn infants were familiarized to a three-dimensional display consisting of a rod which moved behind a central occluder, so that , only the top and bottom of the rod were visible. The infants’ eyes were 38 cm from the rod and the occluder was 15 cm in front of the rod, a separation intended to ensure that the gap between the two was detected by the infants. On subsequent test trials the infa...

to how more could be done, before old age, and indeed before retirement, to develop interests and skills which may stand their possessor in good stead later. Most important for many is the feeling of being wanted and loved by someone: and naturally by one's children, if one has them. But one of today's tragedies is the difficulty middle-aged or younger people have in feeling, or at least in dis...

Specific mRNAs are transported to dendrites where their translation may modify synaptic plasticity. In this issue of Neuron, Kanai et al. use affinity chromatography and mass spectrometry to identify a large number of new factors that associate with kinesin, a molecular motor, and employ siRNA technology to demonstrate their importance for RNA transport in neurons.
