Chemistry &Biodiversity, EarlyView.ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Pediatric optic neuritis [PDF]
Neurology, 2016 Optic neuritis (ON) is a common presenting symptom in pediatric CNS demyelinating disorders and may be associated with dramatic visual loss. Knowledge regarding clinical presentation, associated diseases, therapy, and outcomes in ON in children has grown over the past decade. These studies have shown that younger children (

Creating optical centrifuge for rapid optical clearing and separation [PDF]
arXiv, 2020 Optical centrifuge has emerged as a promising tool for achieving centrifuge motion of particles in many fields. Herein, we report a novel optical centrifuge, as driven by optical lateral force arising from transverse phase gradient of light in holographic optical tweezers.

Integrated waveguide-based acousto-optic modulation with near-unity conversion efficiency [PDF]
arXiv, 2023 Acousto-optic modulation in piezoelectric materials offers the efficient method to bridge electrical and optical signals. It is widely used to control optical frequencies and intensities in modern optical systems including Q-switch lasers, ion traps, and optical tweezers.

Cavity-Enabled Self-Electro-Optic Bistability in Silicon Photonics [PDF]
Optics Letters, Vol. 39, Issue 13, pp. 3864-3867 (2014), 2014 We propose a new type of bistable device for silicon photonics, using the self-electro-optic effect within an optical cavity. Since the bistability does not depend on the intrinsic optical nonlinearity of the material, but is instead engineered by means of an optoelectronic feedback, it appears at low optical powers.

Rapidly developing Optic Neuritis secondary to Ethambutol: possible mechanism of injury [PDF]
, 2005 Optic neuritis has been described among the toxic effects of Ethambutol. This side effect is dose related. The mean duration of Ethambutol induced optic neuritis (EON) is three months.

A longitudinal study of abnormalities on MRI and disability from multiple sclerosis [PDF]
, 2002 Background: In patients with isolated syndromes that are clinically suggestive of multiple sclerosis, such as optic neuritis or brain-stem or spinal cord syndromes, the presence of lesions as determined by T2-weighted magnetic resonance imaging (MRI) of ...

Environmental and Molecular Mutagenesis, EarlyView.Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Scientific ReportsOptic neuritis is often an initial symptom in multiple sclerosis (MS) or clinically isolated syndrome (CIS), yet comprehensive studies using the 2017 McDonald criteria for MS are scarce. Patient records from our academic centre (2010–2018) were reviewed.
