Influence of Correlated Disorder Potentials on the Levitation of Current Carrying States in the Quantum Hall Effect [PDF]

, 2001
The disorder driven quantum Hall to insulator transition is investigated for a two-dimensional lattice system. We consider a Gaussian correlated random potential, study the behaviour of the current carrying states and trace their energetical position when the disorder strength is increased.

Cranial functional (psychogenic) movement disorders [PDF]

, 2015
Functional (psychogenic) neurological symptoms are frequently encountered in neurological practice. Cranial movement disorders—affecting the eyes, face, jaw, tongue, or palate—are an under-recognised feature of patients with functional symptoms. They can

Autophagy in cancer and protein conformational disorders

FEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Levitation of quantum Hall critical states in a lattice model with spatially correlated disorder [PDF]

Phys. Rev. B 67, 195307 (2003), 2003
The fate of the current carrying states of a quantum Hall system is considered in the situation when the disorder strength is increased and the transition from the quantum Hall liquid to the Hall insulator takes place. We investigate a two-dimensional lattice model with spatially correlated disorder potentials and calculate the density of states and ...

Melatonin for rapid eye movement sleep behavior disorder in Parkinson's disease : a randomised controlled trial [PDF]

, 2019
Background Melatonin may reduce REM-sleep behavior disorder (RBD) symptoms in Parkinson's disease (PD), though robust clinical trials are lacking. Objective To assess the efficacy of prolonged-release (PR) melatonin for RBD in PD.

Brucella NyxA and NyxB dimerization enhances effector function during infection

FEBS Letters, EarlyView.
Brucella abortus thrives inside cells thanks to the translocation of effector proteins that fine‐tune cellular functions. NyxA and NyxB are two effectors that destabilize the nucleolar localization of their host target, SENP3. We show that the Nyx proteins directly interact with each other and that their dimerization is essential for their function ...

Radiological markers of CSF α-synuclein aggregation in Parkinson’s disease patients

npj Parkinson's Disease
Alpha-synuclein (αS) aggregation is a widely regarded hallmark of Parkinson’s disease (PD) and can be detected through synuclein amplification assays (SAA).

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

FEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
