The diagnosis of acute abdomen can be difficult in patients with spinal injuries. We reviewed all the 1039 case records of patients admitted with spinal injuries to the Queen Elizabeth National Spinal Injuries Unit, Glasgow over a 7-year-period and found 5 (0.48%) cases of acute abdomen that required surgical intervention and were not caused by ...

In general, the spleen accompanied by abnormal abdomen is hypertrophied. However, if the spleen size is originally small, it is hard to detect the splenic enlargement due to abnormal abdomen by simply measure the size. On the contrary, the spleen size of a person having a normal abdomen may be large by nature. ...

A microscopic model is used to determine analytically the macroscopic conformational properties of dendritic polymers with interactive branching points. Three mean square distances are calculated which determine the extension of the k generation from the origin, the sizes of the branches in each generation and the average distances between symmetrical ...

The impact of structure in modulating synaptic signals originating in dendrites is widely recognized. In this study, we focused on the impact of dendrite morphology on a local spike generating mechanism which has been implicated in hormone secretion, the after depolarization potential (ADP). Using multi-compartmental models of ...

In chironomid midges, the development of head and thorax in the embryo requires the function of cytoplasmic determinants localized near the anterior pole of the egg. Experimental inactivation of these determinants causes a dramatic switch in the developmental program of the embryo. Instead of the normal segment pattern, the aberrant pattern "double abdomen" is formed. Head, ...

The Australian buprestid beetle Merimna atrata (Coleoptera: Buprestidae) approaches forest fires because its larvae develop in freshly burnt wood. So far nothing is known about possible sensory systems enabling the beetles to detect fires and to cope with the thermal environment close to the flames. We found that M. atrata has two pairs of infrared (IR) organs on the ventrolateral sides of the ...

In both insects and mammals, olfactory receptor neurons (ORNs) expressing specific olfactory receptors converge their axons onto specific glomeruli, creating a spatial map in the brain. We have previously shown that second order projection neurons (PNs) in Drosophila are prespecified by lineage and birth order to send their dendrites to one of approximately 50 glomeruli in the ...

Powder particles generated by the RSR centrifugal atomization process exhibit at least two distinct types of microstructure. When a high melt superheat is maintained during atomization, the powder particles possess the familiar coarse grained dendritic microstructures. On the other hand, when the melt superheat is reduced by increasing the heat flow to the disc of the rotary ...

Virtually all pediatric cases of Neisseria gonorrhoeae originate from contact with an infected adult. A cutaneous abscess caused by N. gonorrhoeae in a child is extremely rare, especially outside the genital area. We report a case of a 22-month-old boy with a gonococcal cutaneous abscess on the abdominal wall and suggest that N. gonorrhoeae should be included in the ...

Dendritic spines receive the majority of excitatory connections in the central nervous system, and, thus, they are key structures in the regulation of neural activity. Hence, the cellular and molecular mechanisms underlying their generation and plasticity, both during development and in adulthood, are a matter of fundamental and practical interest. Indeed, a better ...
