Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Quantitative evaluation of rock brittleness and fracability based on elastic-wave velocity variation around borehole

open access: yesPetroleum Exploration and Development, 2016
Brittleness and fracability are two important rock properties in hydraulic fracturing of unconventional reservoirs. Based on the variation of compressional and shear velocity around borehole using acoustic measurement, an effective technique is developed

Hypoplastic and Accessory Radial Arteries: A Case Report [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Arterial variations in the upper extremity occur in a high prevalence. The radial artery is a terminal branch of the brachial artery in the cubital fossa. This artery is used in some treatment interventions and it’s variation is important for clinicians.

Baseline Regional Cholinergic Denervation Predicts Cognitive Trajectories in Moderate Parkinson Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

Prevalence of Radial Artery Variants and Their Relationship with Clinical Considerations of the Antebrachial Region: Systematic Review and Meta-Analysis

open access: yesDiagnostics
Background: The radial artery (RA) is one of the terminal branches of the brachial artery, extending along the lateral forearm, crossing the anatomical snuffbox, and contributing to the palmar arches. Anatomical variations in the RA are of great clinical

Four patients with a clinically significant radial artery anomaly

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2019
The superficial radial artery is an anatomic variant in which the radial artery passes superficial to the tendons of the anatomic snuffbox. Cadaver studies have shown its incidence to be 0.5% to 1%.

Paramagnetic Rim Lesions Are Associated With Trans‐Synaptic Degeneration of the Visual Pathway in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Retrograde trans‐synaptic degeneration (rTSD) from posterior visual pathway lesions in multiple sclerosis (MS) is characterized by hemi‐macular ganglion cell‐inner plexiform layer (GCIPL) thinning and contralateral visual field loss.

Superficial radial artery- a rare variation and its clinical significance

open access: yesNational Journal of Clinical Anatomy, 2014
During routine dissection of upper limb, a variation in the origin of radial artery was observed in a female cadaver of about 60 years. The radial artery is usually a smaller terminal branch of the brachial artery in the forearm. On the right side of the
