CT‐Based Comparison of Tracheostomy Placement Accuracy: Open Versus Percutaneous Approaches

open access: yesThe Laryngoscope, EarlyView.
This study provides the first objective CT‐based comparison of tracheostomy placement accuracy between open surgical and percutaneous techniques in 503 patients. Both methods achieved comparable stoma positioning relative to the cricoid cartilage, while patient factors and surgeon expertise had a greater impact on placement accuracy than the surgical ...

In Vivo Mapping of Catecholaminergic Loss and Iron Deposition in Huntington's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background The pathophysiology of Huntington's disease (HD) remains obscure. Magnetic resonance imaging (MRI) can reveal in vivo molecular changes related to disease pathology. Objectives To investigate catecholaminergic neuronal integrity and subcortical brain iron accumulation in HD employing neuromelanin‐sensitive MRI, and quantitative ...

A guide to nestling development and aging in altricial passerines [PDF]

open access: yes, 2007
Nestling growth and development studies have been a topic of interest for a greater part of the last century (Sutton 1935, Walkinshaw 1948) and continue to be of interest today. This is not surprising since studies on nestling growth can provide a wealth

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Mediterranean Versus Western Diet Effects on Obesity Phenotypes and Adipose Tissue Transcriptional Profiles in Female Monkeys

open access: yesObesity, EarlyView.
ABSTRACT Objective Obesity, or excessive body fat, is a significant health risk factor. Western diets (WD) contribute to metabolic dysfunction and obesity, while Mediterranean diets (MD) improve metabolic health. This study examined the contrasting effects of WD versus MD on visceral and subcutaneous adipose tissues (VAT, SAT) using a randomized ...

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Linking to images and AI‐based identification tools—The only way for Flora projects to survive

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Floras are comprehensive and authoritative catalogues of plants growing in an area of interest. They help people find and name plants, which is achieved by a combination of images, drawings, and text, rarely also maps. Like other catalogues (lexica, dictionaries, telephone books), Floras will not survive unless they move online and become portable ...

Associations of Vestibular Disorders With Risk of All‐Cause and Cause‐Specific Dementia: A Longitudinal Cohort Study in UK Biobank

open access: yesSensory Neuroscience, EarlyView.
ABSTRACT To explore associations of vestibular disorders with all‐cause and cause‐specific dementia and underlying biological mechanisms/neuroimaging changes. A population‐based cohort study of 406,348 UK Biobank participants was conducted. Inverse probability of treatment weighting (IPTW) balanced baseline covariates, and Cox proportional hazards ...
