Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin‐D28k, parvalbumin, glial fibrillary acidic protein, and Iba‐1 during pre‐hibernation and hibernation

open access: yesThe Anatomical Record, EarlyView.
Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...

Fresh insights into the light‐induced pineal gland circadian rhythm transmission mechanism derived from mRNA and miRNA profiling

open access: yesAnimal Research and One Health, EarlyView.
Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

Sleep Spindle Abnormalities in Preschool Children With Autism Spectrum Disability: Insights From Nap Polysomnography

open access: yesAutism Research, EarlyView.
ABSTRACT Sigma power and sleep spindles are key elements of Non‐Rapid Eye Movement (NREM) sleep. They reflect anatomical and physiological properties of brain circuits, are linked with various behavioral outcomes in typically development (TD) children, and undergo significant modifications during development.

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.

Ubiquitination in cancer: mechanisms and therapeutic opportunities

open access: yesCancer Communications, EarlyView.
Abstract Ubiquitination, a key post‐translational modification, plays an essential role in tumor biology by regulating fundamental cellular processes, such as metabolism and cell death. Additionally, it interacts with other post‐translational modifications, which are closely linked to tumorigenesis, tumor progression, the tumor microenvironment, and ...

Sleep and Circadian Rhythm Association with Sperm Head Defects in Infertile Males

open access: yesJournal of Infertility and Reproductive Biology
Male factor infertility can be due to defects in the semen quality and sperm parameters. The sperm head contains the acrosomal enzymes and the DNA required for fertilization.

Theoretical Analysis of d‐Serine and d‐Asparagine as Biomarkers for Glomerular Filtration Rate

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a major global health issue, requiring accurate and noninvasive renal function assessment. Glomerular filtration rate (GFR) is the standard measure, but current methods, including inulin clearance and creatinine‐based estimation, have limitations in accuracy, invasiveness, and practicality.
