    Vascular-metabolic and GABAergic Inhibitory Correlates of Neural Variability Modulation. A Combined fMRI and PET Study.Timothy J. Lane - 2018 - Neuroscience 379:142-151.
    Neural activity varies continually from moment to moment. Such temporal variability (TV) has been highlighted as a functionally specific brain property playing a fundamental role in cognition. We sought to investigate the mechanisms involved in TV changes between two basic behavioral states, namely having the eyes open (EO) or eyes closed (EC) in vivo in humans. To these ends we acquired BOLD fMRI, ASL, and [18F]-fluoro-deoxyglucose PET in a group of healthy participants (n = 15), along with BOLD fMRI and (...)

  4. Status of Cacao (Theobroma cacao L.) production on its challenges and prospect in Zamboanga del Norte Province in the Philippines.Mark Patalinghug - 2022 - International Journal of Agricultural Technology 18 (3):1075-1092.
    Examining the status of cacao production, challenges, and prospects of cacao farmersin Zamboanga del Norte province were done in this study. The investigation revealed that cacaofarming was practiced by males (244 or 65.10%) and female cacao farmers (34%) who areprimarily married with secondary educational backgrounds. Most cacao farmers were theirproductive age ranging from 50-59 years old (42.93%), 40-49 years old (34.4%). However,fewer young people engaged in cacao farming aged below 40 years old (7.46%). The primaryoccupation of the respondents was farming (...)

  5. Integrating Multicellular Systems: Physiological Control and Degrees of Biological Individuality.Leonardo Bich - 2023 - Acta Biotheoretica 72 (1):1-22.
    This paper focuses on physiological integration in multicellular systems, a notion often associated with biological individuality, but which has not received enough attention and needs a thorough theoretical treatment. Broadly speaking, physiological integration consists in how different components come together into a cohesive unit in which they are dependent on one another for their existence and activity. This paper argues that physiological integration can be understood by considering how the components of a biological multicellular system are controlled and coordinated in (...)

    Hyperthermia-Induced Vasoconstriction: A Physiological Counter Mechanism.Rowena Kong - 2023 - Journal of Psychiatry and Psychology Research 6 (S2):4.
    The paradoxical phenomena of hyperthermia-induced vasoconstriction, hyperthermia- induced hypothermia, and hyperthermia induced arterial vasoconstriction have been observed in animal heatstroke clinical case studies. We attempt to explain the basic mechanism behind such findings in terms of the principle of body heat conservation and natural countermeasure against heat exposure through reduction in the extent of vascular surface area exposed. One study which examined the outcome of heating a rabbit carotid artery produced graded vasoconstriction which is proportional to temperature increase. These (...)

    Enhancing Reduced Risk of Obese Patient Exposure to COVID-19 Attack through Food and Nutritional Adjustment.Patience Abosede Olunusi & Motunrayo Risikat Asunmo - 2023 - International Journal of Home Economics, Hospitality and Allied Research 2 (2):206-218.
    The COVID-19 pandemic is a major global challenge. There are several risk factors associated with mortality in patients with COVID-19, including age, gender, diabetes mellitus, cerebrovascular, cardiovascular, and pulmonary diseases. Among these factors, patients with cardiovascular disease, diabetes mellitus, and obesity have the highest mortality rates. This paper aims to review how adjusting food and nutrition can help reduce the risk of obese patients contracting COVID-19. Various literature sources were examined, including studies on the genetics of obesity and the consequences (...)

  9. Expert System for Polymyalgia Rheumatic.Massoud Agha & Abdallah Jarghoon - 2017 - International Journal of Engineering and Information Systems 1 (4):125-137.
    Polymyalgia Rheumatica (PMR) presents with a broad spectrum of clinical manifestations and almost exclusively occurs in the population aged over 50 years. After rheumatoid arthritis, PMR is the second most common autoimmune rheumatic disorder. Visual loss is the most feared complication in temporal arteritis, and extracranial arteries. No specific laboratory parameter exists for diagnosis of PMR. Imaging techniques such as ultrasonography, MRI or F-fluorodeoxyglucose PET may be helpful in the diagnosis and evaluation of the extent of vascular involvement in (...)

  10. Estabelecimento da Gestação nos Animais.Emanuel Isaque Cordeiro da Silva - manuscript
    OBJETIVO A gestação nos mamíferos domésticos é um processo fisiológico que implica mudanças físicas, metabólicas e hormonais na fêmea, que culminam com o nascimento de um novo indivíduo. Desta forma, a compreensão de tais mudanças e como estas favorecem um ambiente ideal de desenvolvimento embrionário inicial, até a placentação e a fisiologia envolvidas durante esses processos é fundamental na tomada de decisões quanto à saúde reprodutiva da fêmea, na seleção de futuras matrizes e até mesmo para a saúde fetal e (...)

  14. Avicultura: Formação do Ovo.Emanuel Isaque Cordeiro da Silva - manuscript
    INTRODUÇÃO O ovo da galinha consiste em uma célula reprodutiva bastante comparável às encontrada nos mamíferos. Todavia, no caso da galinha, essa célula reprodutiva localiza- se na superfície da gema, sendo preenchida por albumens, membranas de casca, casca e cutícula. O ovário é responsável pela formação da gema; as porções restantes do ovo originam-se no canal do oviduto. • OVÁRIO No momento do desenvolvimento precoce do embrião, existem dois ovários e dois ovidutos, entretanto o conjunto ovário-oviduto direito atrofia-se, deixando apenas (...)

  19. Cerebral blood flow autoregulation is impaired in schizophrenia.Hsiao-Lun Ku, Timothy Lane & et al - 2017 - Schizophrenia Research:xx-yy.
    Patients with schizophrenia have a higher risk of cardiovascular diseases and higher mortality from them than does the general population; however, the underlying mechanism remains unclear. Impaired cerebral autoregulation is associated with cerebrovascular diseases and their mortality. Increased or decreased cerebral blood flow in different brain regions has been reported in patients with schizophrenia, which implies impaired cerebral autoregulation. This study investigated the cerebral autoregulation in 21 patients with schizophrenia and 23 age- and sex-matched healthy controls. None of the participants (...)
