Slow-downs of fertility decline: When should we call it a 'fertility stall'?

open access: yesDemographic Research, 2022
Background: The phenomenon of fertility stalls in Africa has recently received much attention in the literature yet hasn't led to clear-cut conclusions.

Favoring recruitment as a conservation strategy to improve the resilience of long‐lived reptile populations: Insights from a population viability analysis

open access: yesEcology and Evolution, 2021
In long‐lived species, although adult survival typically has the highest elasticity, temporal variations in less canalized demographic parameters are the main drivers of population dynamics.

Acetyl-cholinesterase-inhibitors slow cognitive decline and decrease overall mortality in older patients with dementia

open access: yesScientific Reports, 2022
We evaluated the effect of Acetyl-cholinesterase-inhibitors (AChEIs) on cognitive decline and overall survival in a large sample of older patients with late onset Alzheimer’s disease (LOAD), vascular dementia (VD) or Lewy body disease (LBD) from a real ...

A Prochlorperazine-Induced Decrease in Autonomous Muscle Activity during Hindlimb Unloading Is Accompanied by Preserved Slow Myosin mRNA Expression

open access: yesCurrent Issues in Molecular Biology, 2023
Skeletal muscle disuse leads to pathological muscle activity as well as to slow-to-fast fiber-type transformation. Fast-type fibers are more fatigable than slow-type, so this transformation leads to a decline in muscle function.

Tai Chi Chuan and Baduanjin Mind-Body Training Changes Resting-State Low-Frequency Fluctuations in the Frontal Lobe of Older Adults: A Resting-State fMRI Study

open access: yesFrontiers in Human Neuroscience, 2017
Age-related cognitive decline is a significant public health concern. Recently, non-pharmacological methods, such as physical activity and mental training practices, have emerged as promising low-cost methods to slow the progression of age-related memory

Impact of Evolutionary Changes in Nonalcoholic Fatty Liver Disease on Lung Function Decline

open access: yesGut and Liver, 2023
Background/Aims: A relationship between fatty liver and lung function impairment has been identified, and both are independently associated with metabolic dysfunction.

SN2007ax : An Extremely Faint Type Ia Supernova [PDF]

open access: yes, 2008
We present multi-band photometric and optical spectroscopic observations of SN2007ax, the faintest and reddest Type Ia supernova (SNIa) yet observed. With M_B = -15.9 and (B-V)max = 1.2, this SN is over half a magnitude fainter at maximum light than any ...

A Physical Model for SN 2001ay, a normal, bright, extremely slowly declining Type Ia supernova [PDF]

open access: yes, 2012
We present a study of the peculiar Type Ia supernova 2001ay (SN 2001ay). The defining features of its peculiarity are: high velocity, broad lines, and a fast rising light curve, combined with the slowest known rate of decline.

OUTBURST DECLINE OF SLOW NOVA RT SERPENTIS (1909) FROM 1940 TO 1993.

open access: yesOdessa Astronomical Publications, 2017
We present observations of the Nova RT Ser (1909) from 1940 to 1978 (pbotograhic magnitudes) and from 1983 to 1993 (B, V, R). Light variations with typical time of 10 years have been detected.
