The Anatomical Record, EarlyView.Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Floodplain environmental change during the younger dryas and holocene: Evidence from the lower kennet valley, south central England [PDF]
, 2006 Many lowland rivers across northwest Europe exhibit broadly similar behavioural responses to glacial-interglacial transitions and landscape development. Difficulties exist in assessing these, largely because the evidence from many rivers remains limited

Development of the Pollen in Some Asclepiadaceae [PDF]
Botanical Gazette, 1901 The development of the sporangia in the Asclepiadaceae studied is the same in general as in other plants, while there are no indications of the phylogenetic history of the reduction in number. The primary sporogenous cells without further division become the pollen mother cells.

British Journal of Clinical Pharmacology, EarlyView.Abstract Aim Individual second‐generation antihistamines may possess differential sedative potential due to the variability in central histamine receptor H1 occupancy. This study aimed to evaluate whether the sedative potential of second‐generation antihistamines is associated with the risk of injury during Japan's pollen season. Methods We conducted a
