Sex differences in movement organization II : the organization of sex differences in movement during food protection, contact righting, skilled reaching and vertical exploration in the rat : the role of gonadal steroids, body morphology, and the central nervous system

Field, Evelyn F., University of Lethbridge. Faculty of Arts and Science January 2006 (has links)
Whether there are sex differences in the kinematic organization of non-reproductive behaviors is rarely addressed. In this thesis, evidence is presented that male and female rats organize their posture and stepping differently during a food protection task, contact righting, skilled reaching, and vertical rearing. Neonatal gonadal steroid exposure can alter sex-typical patterns of movement organization. Whether these differences are due to sex differences in body morphology or central nervous system (CNS) was also addressed using gravid females and tfm males. The results reveal that sex differences in movement are CNS based. Furthermore, the expression and choice of sex-typical patterns of movement can be altered by CNS injury. Finally, evidence is presented that sex differences in movement organization are also present in marsupials and insects. The implications of these results for our understanding of the evolution of sex differences in CNS anatomy and behavior will be discussed. / xvi, 249 leaves : ill. ; 28 cm.

Kineziterapijos ir funkcinės treniruotės užsiėmimų įtaka vaikų su cerebriniu paralyžiumi centrinės nervų sistemos funkcinės būklės rodikliams / The functional state of the central nervous system of the children with spastic hemiplegia in physiotherapy and functional training

Daniusevičiūtė, Laura 19 May 2005 (has links)
The purpose of the study was to estimate the functional state of the central nervous system of the children with spastic hemiplegia in physiotherapy and functional training. The subjects were 18 children with spastic hemiplegia and 32 nondisabled pupils, age 8-13 years old. In our study we used following methods – romberg test, electronic balance board, tapping test, mathematic statistics. The obtained results showed that the evaluations of the balance of the children with spastic hemiplegia were significantly better in sagittal plane than frontal. The functional state of central nervous system of the children with spastic hemiplegia and nondisabled pupils showed high changes in freqeuncy of movements during tapping test. The used physiotherapy improved the functional state of the central nervous system of the children with spastic hemiplegia. The functional training programm were more effective than the used physiotherapy programm.

Localisation of equilibrative nucleoside transporter 3 (ENT3) in mouse brain

Roberts, Lauren Emilienne 12 January 2015 (has links)
Adenosine is an essential purine nucleoside of particular importance within heart and brain. The widespread and diverse actions of adenosine, driven by activation of cell surface receptors, include regulation of sleep/arousal and neuroprotective properties. The mechanisms involved in regulating adenosine concentrations remain poorly understood but are critical to signaling pathways as they determine the availability of adenosine at corresponding receptors within the extracellular space. The equilibrative nucleoside transporter (ENT) family, bi-directional, Na+-independent nucleoside transporters, are key components in both the release and uptake of adenosine. This study has been conducted to investigate ENT3, a novel member of the ENT family. Our work has demonstrated ENT3 to be expressed throughout brain, located in cortex, cerebellum, striatum and hippocampus, at similar levels. Neurons and astrocytes, but not microglia, showed intracellular ENT3 localisation. This was confirmed by differential centrifugation, of cortex and cerebellum, which suggests ENT3 to be found within the cytoplasm.

Canine Neural Angiostrongyliasis

Lunn, Julian Alexander January 2007 (has links)
Master of Veterinary Clinical Studies / Summary Canine Neural Angiostrongyliasis (CNA) is caused by the obligatory neural migration of Angiostrongylus cantonensis larvae in dogs. Characteristically, cases are juvenile dogs with progressive CNS dysfunction characterised by hyperaesthesia and often associated with eosinophilic pleocytosis of the CSF. In Australia, most cases occur between March and June. The rat lungworm, A cantonensis was first described by Chen in 1935 in Canton, China. While initially called Pulmonema cantonensis the parasite was later reclassified as A cantonensis. A disease diagnosed as eosinophilic meningoencephalitis was first described in 1944 in Taiwan. The same disease was reported in 1948 in the East Caroline Islands but it was not until 1961 that A cantonensis was confirmed as the aetiological agent when a patient in a Hawaiian mental institution, who had died of eosinophilic meningoencephalitis, had A cantonensis larvae recovered from the brain and spinal cord. The first reports of animals infected with A cantonensis were made by Mason in 1976 when he described a syndrome occurring in puppies in the Brisbane area, characterised by urinary incontinence, hind limb paresis and hyperaesthesia, often associated with eosinophilic pleocytosis of the CSF. Reports of infection in other species followed including macropods, bats, horses, primates and birds. Twenty-two cases of suspected CNA were collected prospectively to compare with those previously described, including 37 cases published by Mason in 1983, and to examine the accuracy of an ELISA used to diagnose human neural angiostrongyliasis in Australia. Samples were collected from two control populations in an attempt to validate the ELISA results. In the prospective series of cases, there was a significantly older subpopulation of dogs in addition to “classical” young dogs, suggesting that this syndrome can occur at any age and should be considered a differential in any dog with progressive neurological disease. The mortality rate in the prospective group was lower than in the published group, which is a reflection of the severity of the disease in younger animals as is the case with human patients. Definitive diagnosis of neural angiostrongyliasis in human patients has been achieved by identifying A cantonensis larvae within the CSF or aqueous humour. In dogs, the only definitive way to diagnose CNA has been via necropsy. While many cases of CNA are characteristic and presumptive diagnosis can be made based on typical history, signalment, clinical signs, CSF analysis and response to glucocorticoids, there appear to be an increasing number of cases occurring in older dogs, that displaying focal, atypical clinical signs or that develop permanent sequelae. Serology has been a useful tool in diagnosing neural angiostrongyliasis in humans. In its current form the ELISA is not sensitive or specific enough to allow a definitive diagnosis of CNA to be made using serum but is useful when applied to CSF specimens. Further refinement of the antigen or using monoclonal rather than polyclonal antibodies may improve the accuracy of the serology. Alternatively, methods such as Western Blot, Immuno-PCR or dot-blot ELISA, which have been successfully used to diagnoses angiostrongyliasis in humans, may be worthy of investigation The major differential diagnosis for CNA is neosporosis. Other differential diagnoses include idiopathic eosinophilic meningoencephalitis, parasitic infections including Toxoplasma gondii, Taenia solium, Gnathostoma spinigerum, visceral larval migrans (Toxocara canis) and schistosomiasis, fungal, bacterial, viral and rickettsial infections as well as neoplasia, trauma, drug reactions and toxicities. Treatment of CNA has been limited to glucocorticoids, however there may be adjunct therapies including anthelmintices, cyclosporine, and matrix metalloproteinase inhibitors. In Mason’s series of cases the use of anthelmintics significantly worsened the clinical outcome for patients. It does not appear, however, that the use of these agents in species other than the dog exacerbates clinical signs. Acquired immunity is short lived in rats and mice, which would suggest the same is true in dogs. Routine heartworm and intestinal parasite prophylaxis appears to have no influence on the occurrence of CNA.
