Purpose: Reflex epilepsies are epileptic disorders in which seizures are consistently provoked by specific, identifiable stimuli-typically sensory or cognitive. In patients with memory-induced seizures, it has long been debated whether the memory acts as the trigger for the seizure or represents its first clinical manifestation.

Methods: We present the case of a 25-year-old woman with reflex seizures triggered by the recollection of specific autobiographical memories.

Graphite exhibits a range of metastable stacking orders, with the number of possible configurations increasing exponentially with the number of layers. Most experimental studies have focused on Bernal and rhombohedral stacking due to the difficulty of identifying and isolating intermediate stacking orders. Motivated by this challenge, we present two atomic force microscopy (AFM) techniques that unambiguously distinguish stacking orders and defects in graphite flakes.

Exosuits have recently been developed as alternatives to rigid exoskeletons and are increasingly adopted for both upper and lower limb therapy and assistance in clinical and home environments. Many cable-driven exosuits have been developed but little has been published on their electromechanical designs and performance. Therefore, this paper presents a comprehensive design and performance analysis of a two degree of freedom tendon driver unit (TDU) for cable-driven wearable exosuits.

Markerless human pose estimation and inertial measurement units are two common methods for human movement analysis. They are cost-effective and easy to use, but their accuracy compared to established optical motion capture methods is yet to be determined for some movements. This study compared the accuracy of IMUs and BlazePose, a markerless monocular 3D human pose estimator, against a marker-based optical system for measuring elbow flexion angles.

Acromegaly is associated with increased mortality rates if not adequately treated. Cardiovascular and metabolic comorbidities are highly prevalent and have long been considered the main cause of death among patients with acromegaly. However, substantial advances in GH/IGF-I-lowering treatment, together with increased awareness and optimized management of other risk factors, have led to major improvements in mortality rates in the 2-3 past decades.

The sebaceous gland (SG) is essential for skin homeostasis by producing sebum to lubricate and protect the skin. Dysfunctions in SG activity are associated with skin disorders such as acne, seborrheic dermatitis, and alopecia. However, its cellular and molecular mechanisms in humans remain poorly understood because most studies have been conducted in mouse models.

Cardiovascular diseases are prevalent entities, especially in emergency patients. Arterial stiffness is a known predictor of cardiovascular risk and mortality and is quantified by carotid-femoral pulse wave velocity (cfPWV). It is caused in part by vascular calcification, but exact details of the underlying mechanisms are yet to be elucidated, and current data suggest endocrine influences.

The skin microbiome plays an important role in health and disease. We have recently shown that microbes living on the skin regulate the immunomodulatory properties of UVR, but the underlying mechanisms remain to be uncovered. Using a preclinical model of immunosuppression against the chemical allergen 2,4-dinitrofluorobenzene, 16S microbiome sequencing, in vitro cultures, high-performance liquid chromatography-mass spectrometry and the generation of gnotobiotic-like mice, we report that acute UVB radiation induces a transient and significant restructuring of bacterial communities on the skin through one of its major photoproducts, cis-urocanic acid.

Photothermal atomic force microscopy-infrared (AFM-IR) combines the nanoscale spatial resolution of AFM with the chemical identification capability of infrared spectroscopy and has thrived in various applications. Currently executed in three major AFM modes (contact, tapping, and peak force tapping) we introduce a fourth variant built upon force volume mode comprising a defined engage, hold, and retract segment in each pixel. IR laser pulsing at a probe resonance frequency during the constant-force hold segment duplicates the resonance-enhanced AFM-IR detection principle of contact mode.

Atopic dermatitis (AD) is an inflammatory skin disease characterized by chronic pruritic eczema with an estimated prevalence of 10% in adults and 50% of them suffering from moderate-to-severe manifestations. Dupilumab, an IL-4/IL-13 inhibitor, is approved for treating moderate-to-severe AD. However, dupilumab-associated ocular surface disease (DAOSD) emerges in up to 60% of dupilumab-treated patients, constituting a major AD-specific adverse event.

Background And Aims: Metreleptin ameliorates hepatic steatosis partially independent of its anorexic action. We previously showed that metreleptin increases hepatic very low-density lipoprotein triglycerides (VLDL1-TG) export in rodents and healthy humans requiring intact hepatic autonomic innervation. The primary aim of this study was to investigate whether metreleptin has anti-steatotic properties in patients with lipodystrophy by increasing VLDL1-TG export.

Atomic force microscopy-based infrared (AFM-IR) techniques have long enabled chemical imaging of surfaces with spatial resolutions down to 10 nm. In this study, we push the boundaries of AFM-IR spatial resolution to the single-nanometer scale, achieving chemical mapping of supramolecular networks at the submolecular level. This breakthrough is made possible by implementing an innovative tapping-mode AFM-IR approach.
