Plasticity of intrinsic excitability across the estrous cycle in hypothalamic CRH neurons

Scientific Reports, 2021
Stress responses are highly plastic and vary across physiological states. The female estrous cycle is associated with a number of physiological changes including changes in stress responses, however, the mechanisms driving these changes are poorly ...

Chronic Stress Detrimentally Affects In Vivo Maturation in Rat Oocytes and Oocyte Viability at All Phases of the Estrous Cycle

Animals, 2021
Background: Stress has been considered as one of the causes of decreased reproductive function in women. However, direct evidence of the effect of chronic stress on oocytes depending on estrous cycle phases is limited.

Solar Cycle Precursors and the Outlook for Cycle 25 [PDF]

arXiv, 2023
Sunspot Cycle 25 over 3 years past the cycle minimum of December 2019. At this point, curve-fitting becomes reliable and consistently indicates a maximum sunspot number of 135+/-10 - slightly larger than Cycle 24's maximum of 116.4, but well below the Cycles 1-24 average of 179 (ranging from 81 for Cycle 6 to 285 for Cycle 19). A geomagnetic precursor,

Analysis pipeline to quantify uterine gland structural variations

Developmental Dynamics, EarlyView.
Abstract Background Technical advances in whole tissue imaging and clearing have allowed 3D reconstruction of exocrine uterine glands deep‐seated in the endometrium. However, there are limited gland structure analysis platforms to analyze these imaging data sets. Here, we present a pipeline for segmenting and analyzing uterine gland shape.

Digital workflows for pathological assessment of rat estrous cycle stage using images of uterine horn and vaginal tissue

Journal of Pathology Informatics, 2022
Assessment of the estrous cycle of mature female mammals is an important component of verifying the efficacy and safety of drug candidates. The common pathological approach of relying on expert observation has several drawbacks, including laborious work ...

Increased Serum Neurofilament Light Chain Concentration Associated With Microglial Morphology Changes in Chronically‐Starved Mice

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is associated with hyperactivity, amenorrhea, and brain atrophy. Weight rehabilitation reversed these symptoms, although the underlying pathophysiological mechanisms are mostly unknown. Serum neurofilament light chain (NfL) levels are widely used as a biomarker of neurodegeneration. Based on neuroimaging studies

Evaluation of anti-Mullerian hormone, antral follicle count and progesterone concentration during estrous cycle in Murrah buffaloes

Indian Journal of Animal Sciences, 2019
An experiment was conducted to study the anti-Mullerian hormone (AMH) concentration, antral follicle count (AFC) and progesterone (P4) concentration during estrous cycle in Murrah buffaloes. Seven animals of 5–10 years were selected for the study.

The interplay between cycle geometry and performance of sudden refrigerators [PDF]

Phys. Rev. E 93, 052150 (2016), 2015
The relation between the geometry of refrigeration cycles and their performance is explored. The model studied is based on a coupled spin system. Small cycle times termed sudden refrigerators, develop coherence and inner friction. We explore the interplay between coherence and energy of the working medium employing a family of sudden cycles with ...

Demographics and viability of an estuarine community of Indo‐Pacific bottlenose dolphins

Marine Mammal Science, Volume 39, Issue 1, Page 59-76, January 2023., 2023
Abstract Wildlife management requires reliable demographic information to assess the status of a population and its vulnerability to threats. This study calculated age class‐ and sex‐specific demographic parameters and assessed the viability of a community of Indo‐Pacific bottlenose dolphins (Tursiops aduncus) resident to the Peel‐Harvey Estuary in ...
