The Association of Sleep Disorders, Obesity, and Sleep-Related Hypoxia with Cancer.

November 19, 2019
Curr Top Med Chem. 2019 Nov 17. doi: 10.2174/1568026619666191118110155. [Epub ahead of print] Abstract Abstract BACKGROUND: Sleep disorders have emerged as potential cancer risk factors. OBJECTIVE: This review discusses the relationships between sleep, obesity, and breathing disorders with concomitant risks of developing cancer. RESULTS: Sleep disorders result in an abnormal expression of clock genes, decreased immunity,...

The physiological significance of the circadian dynamics of the HPA axis: Interplay between circadian rhythms, allostasis and stress resilience.

November 17, 2019
Horm Behav. 2019 Apr;110:77-89. doi: 10.1016/j.yhbeh.2019.02.018. Epub 2019 Mar 15. Abstract Circadian time-keeping mechanisms preserve homeostasis by synchronizing internal physiology with predictable variations in the environment and temporally organize the activation of physiological signaling mechanisms to promote survival and optimize the allocation of energetic resources. In this paper, we highlight the importance of the robust circadian...

[Radiofrequency electromagnetic fields, mobile phones, and health effects: where are we now?]

November 9, 2019
[Article in Italian] Epidemiol Prev. 2019 Sep-Dec;43(5-6):374-379. doi: 10.19191/EP19.5-6.P374.107. Abstract This paper aims to present useful elements for framing the issue of exposure to radio frequencies (RFs), in particular those related to telecommunications, and the possible effects on health also in the light of the rapid evolution of technologies (the advent of 5G). New developments in...

Scoping Review of the Potential Health Effects of Exposure to Extremely Low-Frequency Electric and Magnetic Fields

November 9, 2019
Crit Rev Biomed Eng. 2019;47(4):323-347. doi: 10.1615/CritRevBiomedEng.2019030211 Abstract Previous studies suggest that extremely low-frequency (ELF) electric and magnetic fields (EMFs) may impact human health. However, epidemiologic studies have provided inconsistent results on the association between exposure to ELF EMFs and various health outcomes. This scoping review reports on primary investigations that were published during the ten-year...

Evaluation in humans of ELF-EMF exposure on chromogranin A, a marker of neuroendocrine tumors and stress.

November 9, 2019
Chronobiol Int. 2019 Nov 4:1-8. doi: 10.1080/07420528.2019.1683857. [Epub ahead of print] Abstract Chromogranin A (CgA), which is a major protein in adrenal chromaffin cells and adrenergic neurons, is a clinically relevant endocrine and neuroendocrine tumor marker including pheochromocytomas, neuroblastomas, and related neurogenic tumors. In this study, we looked at the effect in humans of chronic daily...

Comparative cyto- and genotoxicity of 900 MHz and 1800 MHz electromagnetic field radiations in root meristems of Allium cepa.

November 9, 2019
Ecotoxicol Environ Saf. 2019 Nov 4;188:109786. doi: 10.1016/j.ecoenv.2019.109786. [Epub ahead of print] Abstract In the last few decades, tremendous increase in the use of wireless electronic gadgets, particularly the cell phones, has significantly enhanced the levels of electromagnetic field radiations (EMF-r) in the environment. Therefore, it is pertinent to study the effect of these radiations on...

We’re all sensitive to light at night, but some are much, much more sensitive than others

November 6, 2019
by Elise McGlashan, PhD & Parisa Vidafar, PhD on November 5th 2019 in Clocks in the Spotlight Humans evolved in an environment with only very bright (sun) or very dim (moon or fire) sources of light. Today, artificial lighting enables us to spend hours per day at intermediate light levels. Our recent study shows that the response of the...

High sensitivity and interindividual variability in the response of the human circadian system to evening light

November 6, 2019
PNAS June 11, 2019 116 (24) 12019-12024; first published May 28, 2019 https://doi.org/10.1073/pnas.1901824116 Significance: Electric lighting has fundamentally altered how the human circadian clock synchronizes to the day/night cycle. Exposure to light after dusk is pervasive in the modern world. We examined group-level sensitivity of the circadian system to evening light and the degree to which sensitivity varies between individuals. We...

Circadian (De)regulation in Head and Neck Squamous Cell Carcinoma

November 6, 2019
PMID: 31151182 PMCID: PMC6600143 DOI: 10.3390/ijms20112662 Abstract Head and neck cancer encompass different malignancies that develop in and around the throat, larynx, nose, sinuses and mouth. Most head and neck cancers are squamous cell carcinomas (HNSCC) that arise in the flat squamous cells that makeup the thin layer of tissue on the surface of anatomical structures in the head and...
