Morphometric Analysis of Lateral Ventricles of the Brain using Magnetic Resonance Imaging and Dissection Method: A Cross-sectional Study [PDF]

open access: yesInternational Journal of Anatomy Radiology and Surgery, 2023
Introduction: The lateral ventricle, which is the largest among all ventricles of the brain, can be divided into the frontal horn, body, posterior horn, and inferior horn. Various methodologies may produce different results in measuring the length of the

Full C-band wavelength-tunable, 250 MHz repetition rate mode-locked polarization-maintaining fiber laser

open access: yesScientific Reports, 2023
We demonstrate a full C-band wavelength-tunable mode-locked fiber laser with a repetition rate of 250 MHz, representing the highest repetition rate for C-band tunable mode-locked lasers thus far to the best of our knowledge.

Correction in the Measurement Error of Water Depth Caused by the Effect of Seafloor Slope on Peak Timing of Airborne LiDAR Waveforms [PDF]

open access: yes한국정밀공학회지, 2017
Light detection and ranging (LiDAR) is one of the most efficient technologies to obtain the topographic and bathymetric map of coastal zones, superior to other technologies, such as sound navigation and ranging (SONAR) and synthetic aperture radar (SAR).

Telomeric replication stress: the beginning and the end for alternative lengthening of telomeres cancers

open access: yesOpen Biology, 2022
Telomeres are nucleoprotein structures that cap the ends of linear chromosomes. Telomeric DNA comprises terminal tracts of G-rich tandem repeats, which are inherently difficult for the replication machinery to navigate.

In Vitro Determination of the Skin Anti-Aging Potential of Four-Component Plant-Based Ingredient

open access: yesMolecules, 2022
The beauty industry is actively searching for solutions to prevent skin aging. Some of the crucial elements protecting cells from the aging process are telomere shortening, telomerase expression, cell senescence, and homeostasis of the redox system ...

An Open-Label Clinical Trial Analyzing the Efficacy of a Novel Telomere-Protecting Antiaging Face Cream

open access: yesCosmetics, 2022
Telomere length, a hallmark of cellular senescence, decreases with age and is associated with age-related diseases. Environmental factors, including dietary and lifestyle factors, can affect the rate at which telomeres shorten, and telomere protection ...

Telomere Length Measurement by Molecular Combing

open access: yesFrontiers in Cell and Developmental Biology, 2020
Telomeres are repetitive regions of DNA bound by specialized proteins at the termini of linear chromosomes that prevent the natural chromosome ends from being recognized as DNA double strand breaks.

Length summation in noise [PDF]

open access: yes, 2019
To investigate the effect of background noise on visual summation, we measured the contrast detection thresholds for targets with or without a white noise mask in luminance contrast. The targets were Gabor patterns placed at 3° eccentricity to either the
