Both report observations of the striking daily closing and opening of <i>Mimosa</i> leaves in controlled environments. This review presents translations of both texts with the aim of staying as faithful as possible to the original French texts. We also present the historical context in which these texts were written and link them to subsequent experiments that aimed at testing the veracity of their central conclusions. In particular, we definitely establish that Mairan himself presented his work to the French Royal Academy of Sciences, while the published report of his observation was authored by Fontenelle, the Secretary of the Academy. In addition, we offer a translation of Mairan's own presentation, based on the hand-written minutes of the academy. Finally, we discuss the decades of work on plant rhythms that laid the foundation for modern experimental chronobiology, including translations and discussion of the insightful and prescient reports by Charles François de Cisternay Dufay, Henri Louis Duhamel du Monceau, Johann Gottfried Zinn, and Wilhelm Pfeffer, which describe their efforts to reproduce and extend Mairan's pioneering observations.</p>","PeriodicalId":15056,"journal":{"name":"Journal of Biological Rhythms","volume":"38 3","pages":"245-258"},"PeriodicalIF":3.5,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9655761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, in most studies, different methods to measure activity in each of these conditions were used, which raised the question of whether the detected change in activity timing could be an artifact. Because locomotor activity and body temperature (Tb) rhythms in rodents are tightly synchronized and because abdominal Tb loggers can provide continuous measurements across field and laboratory, we monitored Tb as a proxy of activity in tuco-tucos transferred from a semi-field enclosure to constant lab conditions. In the first stage of this study (\"Tb-only group,\" 2012-2016), we verified high incidence (55%, <i>n</i> = 20) of arrhythmicity, with no consistent diurnal Tb rhythms in tuco-tucos maintained under semi-field conditions. Because these results were discrepant from subsequent findings using miniature accelerometers (portable activity loggers), which showed diurnal activity patterns in natural conditions (<i>n</i> = 10, \"Activity-only group,\" 2016-2017), we also investigated, in the present study, whether the tight association between activity and Tb would be sustained outside the lab. To verify this, we measured activity and Tb simultaneously across laboratory and semi-field deploying both accelerometers and Tb loggers to each animal. These measurements (<i>n</i> = 11, \"Tb + activity group,\" 2019-2022) confirmed diurnality of locomotor activity and revealed an unexpected loosening of the temporal association between Tb and activity rhythms in the field enclosures, which is otherwise robustly tight in the laboratory.</p>","PeriodicalId":15056,"journal":{"name":"Journal of Biological Rhythms","volume":"38 3","pages":"278-289"},"PeriodicalIF":3.5,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10004294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She was a research scientist and a professor at a time when few women held such jobs. For many years, she was a single mother (a widow) and was able to raise her family in a beautiful home. In her research, she helped to define a key function, the phase response curve (PRC) to light (DeCoursey, 1960a, 1960b). Her behavioral studies were meticulous and wonderfully detailed. She worked with others to publish what remains our core chronobiology textbook (Dunlap et al., 2004). In her later career, she conducted some of our field’s most impactful “clocks in the wild” studies (DeCoursey, 2014). Pat’s career as a Professor of Biological Sciences at the University of South Carolina included both laboratory and field studies. She studied flying squirrels and golden hamsters, and in her naturalistic studies, chipmunks, white-tailed antelope squirrels, and golden-mantled ground squirrels. From 2006 to 2019, Pat directed the W. Gordon Belser Arboretum, a 10-acre teaching forest for the university. Pat’s early life was unusual for several reasons. She was a triplet with an identical twin sister. Her family spent one summer camping in northern wilderness forests. When Pat was in fourth grade, she moved to Washington, DC, but she maintained a love of the wilderness. In high school in New York City, she completed a census of all the songbirds in a forest in Long Island, winning finalist status in the 1950 Westinghouse Science Talent Search. She attended Cornell University for her undergraduate degree in zoology and then received her PhD in zoology and biochemistry at the University of Wisconsin–Madison. She conducted postdoctoral research for 2 years at the Max-Planck Institute in Erling-Andechs, Germany, with Jurgen Aschoff. She even served as one of the early subjects of a “bunker” experiment, living in temporal isolation for 28 days. Her enthusiasm for science is nicely reflected in the text of a letter she wrote to her sister Cynthia at the time:","PeriodicalId":15056,"journal":{"name":"Journal of Biological Rhythms","volume":"38 3","pages":"242-244"},"PeriodicalIF":3.5,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9649129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have previously established a self-rating of biological rhythm disorder for adolescents (SBRDA). However, we did not externally validate the SBRDA against objective measures of biological rhythms such as dim light melatonin onset (DLMO)-the gold standard of the endogenous circadian phase. The purpose of this study was to verify the effectiveness of SBRDA in identifying individuals with biological rhythm disorders. Our participants were 42 (47.2%) boys and 47 (52.8%) girls with an average age of 18.5 ± 1.2 years. Saliva samples were collected from 4 h before bed time to 2 h after sleep every 60 min in a dim-light (<50 lx) laboratory environment. Biological rhythm parameters were assessed using questionnaires, including SBRDA, MEQ, and MCTQ. The mean DLMO time (h) was 22.2 ± 1.9. The DLMO correlated significantly with the SBRDA score (<i>r</i> = 0.33, <i>p</i> < 0.001), MEQ score (<i>r</i> = -0.24, <i>p</i> < 0.05), and MSFsc (<i>r</i> = 0.26, <i>p</i> < 0.05). ROC curve analysis showed that SBRDA was of diagnostic value for biological rhythm disorder (<i>p</i> < 0.05). Our observations demonstrate that SBRDA, which is consistent with MEQ and MCTQ, can be used to reflect endogenous circadian rhythm disorders in young adults.

Exposure of target tissues to the active form of the drug and cytotoxicity display variations depending on the chronopharmacokinetics. For anticancer drugs with narrow therapeutic ranges and dose-limiting side effects, it is particularly important to know the temporal changes in pharmacokinetics. A previous study indicated that pharmacokinetic profile of capecitabine was different depending on dosing time in rat. However, it is not known how such difference is attributed with respect to diurnal rhythm. Therefore, in this study, we evaluated capecitabine-metabolizing enzymes in a diurnal rhythm-dependent manner. To this end, C57BL/6J male mice were orally treated with 500 mg/kg capecitabine at ZT1, ZT7, ZT13, or ZT19. We then determined pharmacokinetics of capecitabine and its metabolites, 5'-deoxy-5-fluorocytidine (5'DFCR), 5'-deoxy-5-fluorouridine (5'DFUR), 5-fluorouracil (5-FU), in plasma and liver. Results revealed that plasma <i>C</i>_max and AUC_0-6h (area under the plasma concentration-time curve from 0 to 6 h) values of capecitabine, 5'DFUR, and 5-FU were higher during the rest phase (ZT1 and ZT7) than the activity phase (ZT13 and ZT19) (<i>p</i> < 0.05). Similarly, <i>C</i>_max and AUC_0-6h values of 5'DFUR and 5-FU in liver were higher during the rest phase than activity phase (<i>p</i> < 0.05), while there was no significant difference in liver concentrations of capecitabine and 5'DFCR. We determined the level of the enzymes responsible for the conversion of capecitabine and its metabolites at each ZT. Results indicated the levels of carboxylesterase 1 and 2, cytidine deaminase, uridine phosphorylase 2, and dihydropyrimidine dehydrogenase (<i>p</i> < 0.05) are being rhythmically regulated and, in turn, attributed different pharmacokinetics profiles of capecitabine and its metabolism.

The purpose of this work was to determine whether chronic alcohol consumption dysregulates the skeletal muscle core molecular clock and clock-controlled genes (CCGs). C57BL/6Hsd female mice (14 weeks old) were fed a control (CON) or alcohol (EtOH) containing liquid diet for 6 weeks.

Chronic alcohol consumption disrupted genes of the core clock including suppressing the rhythmic peak of expression of <i>Bmal1</i>, <i>Per1, Per2</i>, and <i>Cry2</i>. Genes involved in the regulation of <i>Bmal1</i> also exhibited lower rhythmic peaks including <i>Reverb</i> α and <i>Myod1</i>.
