Lockdown time, time loops, and the crisis of the future
Amidst the Covid-19 lockdowns of 2020 and 2021 in the United States and United Kingdom, a fantasy took hold that life under lockdown was like living...

Non-invasive quantification of pressure–volume loops in patients with Fontan circulation
BackgroundPressure–volume (PV) loops provide comprehensive information of cardiac function, but commonly implies an invasive procedure under general...

Radiological presence of vascular loops in the cerebellopontine angle region in patients with unilateral Ménière’s disease
ObjectiveThe relationship between vascular compression of the vestibulocochlear nerve and audio-vestibular symptoms remains controversial. We aimed...

A randomised clinical trial comparing outcomes of a single digit volar plate injury — Buddy loops versus dorsal thermoplastic orthosis in a neutral position: study protocol
BackgroundVolar plate injuries are a common hand injury and complications associated with this injury such as a fixed flexion deformity, persistent...

Ascites exosomal lncRNA PLADE enhances platinum sensitivity by inducing R-loops in ovarian cancer
Cisplatin resistance is a major cause of therapeutic failure in patients with high-grade serous ovarian cancer (HGSOC). Long noncoding RNAs (lncRNAs)...

Superior temporal gyrus and cerebellar loops predict nonsuicidal self-injury in major depressive disorder patients by multimodal neuroimaging
In major depressive disorder (MDD) patients, nonsuicidal self-injury (NSSI) is a common comorbidity, and it is important to clarify the underlying...

Dynamic pressure–volume loop analysis by simultaneous real-time cardiovascular magnetic resonance and left heart catheterization
BackgroundLeft ventricular (LV) contractility and compliance are derived from pressure–volume (PV) loops during dynamic preload reduction, but...

Complex reconstructive microsurgery cases: the role of arteriovenous loops
BackgroundIn free-flap reconstructive microsurgery, arteriovenous loops can be a useful tool when adequate recipient vessels are absent. We present a...
