1. Clinical evaluation of biological rhythm domains in patients with major depression
Objective: Sleep, physical activity, and social domains of biological rhythm disruptions may have specific effects on the symptom cluster and severity of depression. However, there is a lack of structured clinical evaluation to specify the domains of biological rhythms in patients with depression. Methods: Ninety drug-naïve subjects with depression and 91

2. Social media during a pandemic: bridge or burden?
Objective: Sleep, physical activity, and social domains of biological rhythm disruptions may have specific effects on the symptom cluster and severity of depression. However, there is a lack of structured clinical evaluation to specify the domains of biological rhythms in patients with depression. Methods: Ninety drug-naïve subjects with depression and 91

3. The Biological Rhythms Interview of Assessment in Neuropsychiatry in patients with bipolar disorder: correlation with affective temperaments and schizotypy
Objective: To assess the relationship of biological rhythms, evaluated by the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN), with affective temperaments and schizotypy. Methods: The BRIAN assessment, along with the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A) and the Oxford-Liverpool Inve

4. Annual tree rings in Piptadenia gonoacantha (Mart.) J.F.Macbr. in a restoration experiment in the Atlantic Forest: potential for dendroecological research
ABSTRACT The tree Piptadenia gonoachantha is widely used in forestry and in forest restoration projects, which require methods for evaluating tree growth. Long-term studies are necessary to determine patterns and detect changes in species growth rhythms. Tree ring analysis provides a precise method for determining age and documenting long-term growth trends

5. The Mood Rhythm Instrument: development and preliminary report
Objective: To describe the initial steps in the development and validation of a new self-reported instrument designed to assess daily rhythms of mood symptoms, namely, the Mood Rhythm Instrument. Methods: A multidisciplinary group of experts took part in systematic meetings to plan the construction of the instrument. Clarity of items, their relevance to ev

6. Changes in the suprachiasmatic nucleus during aging: implications for biological rhythms
Animals have neural structures that allow them to anticipate environmental changes and then regulate physiological and behavioral functions in response to these alterations. The suprachiasmatic nucleus of the hypothalamus (SCN) is the main circadian pacemaker in many mammalian species. This structure synchronizes the biological rhythm based on photic informa

7. Biological rhythms and vector insects
The adjustment of all species, animals and plants, to the Earth’s cyclic environments is ensured by their temporal organisation. The relationships between parasites, vectors and hosts rely greatly upon the synchronisation of their biological rhythms, especially circadian rhythms. In this short note, parasitic infections by Protozoa and by microfilariae hav

8. Morning and nocturnal serum melatonin rhythm levels in patients with major depressive disorder: an analytical cross-sectional study
CONTEXT AND OBJECTIVE: The pineal gland is an adaptive organ that precisely regulates the biological rhythms of melatonin brain hemostasis. Variation in the regulation of melatonin rhythms is a likely cause of depressive disorder. The purpose of this study was to measure serum melatonin levels in patients with major depressive disorder (MDD) and normal contr

9. Estudo da ontogênese dos ritmos biológicos em neonatos humanos e ratos. / Study of the ontogenesis of biological rhythms in newborns humans and rats.
Fatores ambientais podem modificar o desenvolvimento dos ritmos biológicos em neonatos, como já demonstrado em ratos. Neste contexto insere-se o estudo de recém-nascidos pré-termo mantidos em unidades de cuidado neonatal. Descrevemos neste trabalho a evolução da ritmicidade no ciclo vigília/sono, atividade/repouso, temperatura do punho e alimentação

10. Papel da melatonina na regulação da ritmicidade circadiana de tecidos periféricos envolvidos com o metabolismo energético: avaliação do perfil diário da expressão dos genes relógio (clock genes). / Role of melatonin in regulating circadian rhythms in peripheral tissues involved in energy metabolism: evaluation of the daily profile of the expression of clock genes.
O metabolismo energético é dependente, dentre outros fatores, de uma temporização circadiana entre os tecidos participantes da regulação metabólica. O processo de sincronização parece depender da expressão dos genes relógio e de mediadores como a melatonina, que associam o oscilador central e os osciladores periféricos. Investigamos o papel da me

11. Caracterização química do núcleo supraquiasmático do primata Cebus apella. / Neurochemical characterization of Cebus apella suprachiasmatic nucleus.
O núcleo supraquiasmático (NSQ), principal relógio biológico circadiano em mamíferos, contem população variada de neurônios produtores de diferentes substâncias neuroativas. Em roedores, as pesquisas avançaram na investigação dos mecanismos moleculares e substâncias neuroativas, que em conjunto determinam a função do relógio biológico. Entre

12. Serotonin and circadian rhythms
All mammal behaviors and functions exhibit synchronization with environmental rhythms. This is accomplished through an internal mechanism that generates and modulates biological rhythms. The circadian timing system, responsible for this process, is formed by connected neural structures. Pathways receive and transmit environmental cues to the central oscillat
