Quantitative analysis of regulatory flexibility under changing environmental conditions [PDF]

open access: yes, 2010
The circadian clock controls 24-h rhythms in many biological processes, allowing appropriate timing of biological rhythms relative to dawn and dusk. Known clock circuits include multiple, interlocked feedback loops.

Clinical Profiles of Dengue Infection during an Outbreak in Northern India

open access: yesJournal of Tropical Medicine, 2016
Introduction. Dengue fever is an arboviral disease, which is transmitted by mosquito vector and presents as varied clinical spectrum of dengue fever (DF), dengue hemorrhagic fever (DHF), dengue shock syndrome (DSS), and expanded dengue syndrome (EDS ...

A bioinformatic analysis identifies circadian expression of splicing factors and time-dependent alternative splicing events in the HD-MY-Z cell line [PDF]

open access: yes, 2019
The circadian clock regulates key cellular processes and its dysregulation is associated to several pathologies including cancer. Although the transcriptional regulation of gene expression by the clock machinery is well described, the role of the clock ...

Cinnamic acid shortens the period of the circadian clock in mice

open access: yesBiochemistry and Biophysics Reports, 2017
Cinnamic acid (CA) derivatives have recently received focus due to their anticancer, antioxidant, and antidiabetic properties. The present study aimed to determine the effects of cinnamic acid on the circadian clock, which is a cell-autonomous endogenous

Probabilistic Timed Automata with Clock-Dependent Probabilities [PDF]

open access: yes, 2017
Probabilistic timed automata are classical timed automata extended with discrete probability distributions over edges. We introduce clock-dependent probabilistic timed automata, a variant of probabilistic timed automata in which transition probabilities ...

Coronary Anomalies: Left Main Coronary Artery Aneurysm

open access: yesCase Reports in Cardiology, 2012
Coronary artery aneurysm is one of the rarest anomalies that we see in our medical practice and they are mostly associated with obstructive lesions due to atherosclerotic changes.

Effects of Kamikihito and Unkei-to on Sleep Behavior of Wild Type and Parkinson Model in Drosophila

open access: yesFrontiers in Psychiatry, 2017
Parkinson’s disease (PD) is the second most common neurodegenerative disease, and it is associated with sleep behavior disorders. In Drosophila melanogaster disease model, human α-synuclein A30P overexpressing flies (A30P PD model) have been shown for ...

Recalibrating the epigenetic clock: implications for assessing biological age in the human cortex

open access: yesbioRxiv, 2020
Human DNA-methylation data have been used to develop biomarkers of ageing - referred to ‘epigenetic clocks’ - that have been widely used to identify differences between chronological age and biological age in health and disease including ...

Evaluating Circadian Dysfunction in Mouse Models of Alzheimer’s Disease: Where Do We Stand?

open access: yesFrontiers in Neuroscience, 2020
Circadian dysfunction has been described in patients with symptomatic Alzheimer’s disease (AD), as well as in presymptomatic phases of the disease. Modeling this circadian dysfunction in mouse models would provide an optimal platform for understanding ...
