The jugular foramen is the main route of venous outflow from the skull and is characterised by laterality based on the predominance of one of the sides. Intracranial meningiomas, paragangliomas (glomus jugulare, from the jugular ganglion of the vagus nerve), schwannomas, metastatic lesions and infiltrative inflammatory processes from surrounding structures such as the middle ear may affect the ...

abstract an experiment was conducted to study growth analysis and evaluation of change in simple non- structural carbohydrates (sucrose, glucose and fructose) during bulb formation of ghermez azarshahr , zargan, safid naishaboor and safid qom cultivars in randomized complete block design containing three replications. seeds were sown in nursery in early february and seedlings were transplanted ...

The experiment was conducted to study the response of summer onion N2 and Naphthalene Acetic Acid (NAA). consisted two factors. Factor A: 4 levels Nitrogen viz. N0-0kg (control), N1-90kg ha-1, N2-110kg ha-1 N3-130kg B: NAA H0-0ppm, H1- 50ppm, H2-100ppm H3-150ppm. laid out in Randomized Complete Block Design with three replications. Results revealed that terms nitrogen, highest bulb diameter (4....

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...

SIR, in the recent paper by Gudziol et al. (2009), treatment of chronic rhinosinusitis lead to an increase of the olfactory bulb volume over a 3-month period, and they concluded that this was due to the restoration of olfactory function. In this letter, we point out another factor that may affect olfactory bulb volume: neuroinflammation regulated neurogenesis. The olfactory bulb volume is great...

The expression pattern of aromatase (ARO), the enzyme converting androgens to estrogens, was analyzed in the olfactory bulb of adult male rats and was compared with the distribution of estrogen receptor beta (ERbeta), the main estrogen receptor isoform expressed in this brain region. A strong ARO immunolabeling obtained with a specificity tested antibody was observed in juxtaglomerular neurons ...

BACKGROUND AND PURPOSE Olfactory bulb atrophy is associated with cognitive dysfunction in Parkinson's and Alzheimer's disease, and with major depression. It has been suggested that olfactory bulb atrophy or dysfunction is therefore a marker of neurodegeneration. Multiple sclerosis (MS) is now also recognized as having a significant neurodegenerative component. Thus, the aim of this study was to...

Olfactory sensory neurons expressing particular olfactory receptors project to specific reproducible locations within the bulb. The axonal guidance cues that organize this precise projection pattern are only beginning to be identified. To aid in their identification and characterization, we generated a transgenic zebrafish line, OR111-7:IRES:Gal4, in which a small subset of olfactory sensory ne...
