Transects

Figure 8-5 shows soil orders that form in relation to climate and vegetation along a transect from the poles to the equator along with processes occurring in the soil. In this conceptual diagram, it is assumed that there is a uniform parent material, similar topography and...

In this example, individual plants of Lupinus sericeus Pursh were collected over a distance measuring approximately 1500 km, including most of the range of the species. hi practice, this amounted to a north-south transect running from the Alberta-British Columbia border to northern Arizona. Lupinus sericeus occurs from southeastern British Columbia and southwestern Alberta to the Kaibab Plateau in northern Arizona,...

Chrysosplenium was discussed above where differences in flavonoid profiles of C. glechomaefolium among populations along a transect ranging from north central California to northern Washington were discnssed (Bohm and Collins, 1979). Chrysosplenium also appears later in the section on polar disjnnctions.

Additional evidence indicating a close relationship between G. bracteata and G. peltata came from the observation of apparent natnral hybridization between them in Quebrada Villagra on Masatierra. A comparison of morphological featnres of both parents and putative hybrid individuals taken along two transects showed clear-cut intermediacy in the latter (Pacheco et al., 1991b). In addition, introgressive hybridization was indicated by the presence of individnals with intermediate valnes... 

Association of Pain, neuropathic pain is defined as pain initiated or caused by a primary lesion, dysfunction in the nervous system". Neuropathy can be divided broadly into peripheral and central neuropathic pain, depending on whether the primary lesion or dysfunction is situated in the peripheral or central nervous system. In the periphery, neuropathic pain can result from disease or inflammatory states that affect peripheral nerves (e.g. diabetes mellitus, herpes zoster, HIV) or alternatively due to neuroma formation (amputation, nerve transection), nerve compression (e.g. tumours, entrapment) or other injuries (e.g. nerve crush, trauma). Central pain syndromes, on the other hand, result from alterations in different regions of the brain or the spinal cord. Examples include tumour or trauma affecting particular CNS structures (e.g. brainstem and thalamus) or spinal cord injury. Both the symptoms and origins of neuropathic pain are extremely diverse. Due to this variability, neuropathic pain syndromes are often difficult to treat. Some of the clinical symptoms associated with this condition include spontaneous pain, tactile allodynia (touch-evoked pain), hyperalgesia (enhanced responses to a painful stimulus) and sensory deficits.
