An investigation into the transcription factors and regulatory mechanisms of Aspergillus

open access: yesFood Safety and Health, EarlyView.
Foodborne pathogen Aspergillus, a prevalent etiologic agent among filamentous fungi, are distinguished by a significant repertoire of transcription factors encoded within their genomes. These regulatory proteins are instrumental in orchestrating key biological processes, including cellular growth, secondary metabolite biosynthesis, mycotoxin production,

Progress of non‐motor symptoms in early‐onset Parkinson's disease

open access: yesIbrain, EarlyView.
This study reviews the research progress related to non‐motor symptoms (NMS) in patients with early onset Parkinson's disease (EOPD), including neuropsychiatric symptoms, autonomic dysfunction, sleep disorders, and sensory disorders and also summarizes the characteristics of NMS in the genetic form of Parkinson's disease (PD).

The circadian system alters thermoregulation depending on the time of day and feeding condition [PDF]

open access: yes, 2009
The circadian rhythm of body temperature (Tb) is a well-known phenomenon. However, it is unknown how the circadian system affects thermoregulation. Food deprivation in mice induces a greater reduction of Tb particularly in the light phase.

Effects of 1267 nm Illumination on Microcirculation Regulatory Mechanisms

open access: yesJournal of Biophotonics, EarlyView.
The question of activation of blood flow regulatory mechanisms during laser illumination remains open to date. This study showed the effect of laser exposure on the microcirculatory bed, which appears in the form of endothelium‐dependent vascular activity.

The Possible Role of Extra-ocular Photoreceptors in the Entrainment of Lobster Circadian Rhythms to Light:Dark Cycles [PDF]

open access: yes, 2013
The American lobster, Homarus americanus, is a decapod crustacean whose daily nocturnal rhythms of activity are driven, in part, by an internal biological clock. While this circadian clock is capable of producing a rhythm of approximately 24 hours on its

Potential Spectral Tuning of the Tapetum Lucidum in a Broadly Distributed Ungulate

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The tapetum lucidum, a biological reflector system found in the eyes of many vertebrate species, enhances visual sensitivity in low light conditions by reflecting light back through the retina. The structure of the ungulate tapetum fibrosum is unique, and its reflectance varies temporally in reindeer (Rangifer tarandus).

Investigating the Relationship Between Circadian Rhythm and Learning-Memory

open access: yesTürk Uyku Tıbbı Dergisi
The circadian rhythm creates many metabolic changes in our body by influencing the activities of suprachiasmatic nucleus and other centers in the cerebrum according to the light-dark conditions within a 24-hour period.
