The development of the osteocranium in the snake Psammophis sibilans (Serpentes: Lamprophiidae)

We confirm the presence of an egg tooth in Psammophis sibilans. We add further observations on the enigmatic fenestra X, showing that it closes rather than merging with the prootic notch. Our observations revealed the likely contribution of the tectum posterius to the occipital roof, the presence of an internal carotid foramen (possibly transitory or variable), and the formation of the initial laterosphenoid pillar. Abstract Non‐avian reptiles are good models to investigate structural and developmental...

Changes in the macroscopic morphology of hip muscles in low back pain

This systematic review indicated that the morphological changes of hip muscles could occur in patients with LBP, but the results are variable and somewhat controversial. However, the majority of high‐quality studies demonstrated that the cross‐sectional area and volume of hip muscles such as the gluteus maximus, gluteus minimus, piriformis, and psoas major muscles generally decrease in patients with LBP. Abstract Low back pain is a major health issue affecting the lumbopelvic muscles. Morphological...

Serotonin and Dopamine Receptor Expression in Solid Tumours Including Rare Cancers

Abstract In preclinical studies serotonin stimulates and dopamine inhibits tumour growth and angiogenesis. Information regarding serotonin and dopamine receptor (5-HTR and DRD) expression in human cancers is limited. Therefore, we screened a large tumour set for receptor mRNA overexpression using functional genomic mRNA (FGmRNA) profiling, and we analysed protein expression and location of 5-HTR1B, 5-HTR2B, DRD1, and DRD2 with immunohistochemistry in different tumour types. With...
