Low‐Dimensional Materials and Van Der Waals Heterostructures for Energy Application: A Comprehensive Review

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Low‐dimensional materials (0D, 1D, and 2D) exhibit unique electronic and physicochemical properties, enabling advanced nanoelectronic and optoelectronic devices. Mixed‐dimensional heterostructures combine these materials to enhance functionality.

WONOEP XVII appraisal: The role of the extracellular matrix in epilepsy

open access: yesEpilepsia, EarlyView.
Abstract The extracellular matrix (ECM) is composed of proteoglycans and glycoproteins that regulate the external environment surrounding neurons, glia, and the vascular system. The ECM is vital for maintaining the structure and function of the brain and also acts as a reservoir for various signaling molecules and neurotransmitters, modulating synaptic

Modeling temporal lobe epilepsy with hippocampal sclerosis in rats using the selective neurotoxin stable substance P‐saporin

open access: yesEpilepsia, EarlyView.
On day 0 adult male and female rats were injected with Stable Substance P‐Saporin (SSP‐SAP) at 4 unilateral sites along the longitudinal axis of the dentate gyrus. Rats exhibited spontaneous electrographic and behavioral reactive seizures between days 4‐6. There was a progressive loss of CA1 and CA3 neurons and a progressive increase in astrocytes over

Triggered Calcium Lightning Programs Cochlear Development

open access: yesExploration, EarlyView.
Summary: Before the onset of hearing, the developing inner ear generates spontaneous calcium signals that are thought to guide maturation. In this study, we discovered a rapid and widespread calcium flash—dubbed “Ca2+ lightning”—originating from supporting cells beneath the sensory hair cells, which triggers coordinated calcium waves across the entire ...

Neural Tube Defects

Tropical Doctor, 1999
Each year spina bifida and anencephaly, the two most common forms of neural-tube defects, occur in 1 in 1000 pregnancies in the United States1 and an estimated 300,000 or more newborns worldwide.2 Although these severe conditions have been recognized since antiquity, never before has progress been so fast and substantive, particularly in the area of ...

Neural Tube Defects

2003
Neural tube defects (spina bifida) are congenital anomalies that result from incomplete closure of the neural tube in utero. This chapter discusses the pathophysiology, epidemiology, medical/surgical treatments, and nursing care for patients with open neural tube defects such as myelomeningocele as well as closed neural tube defects.

Homocysteine and Neural Tube Defects

The Journal of Nutrition, 1996
It is now well established that folic acid, when taken periconceptionally, can prevent many neural tube defects. It is also becoming clear that folic acid does not work by correcting a nutritional deficiency in pregnant women. Rather, it appears that a metabolic defect is responsible for these neural tube defects and that this defect or defects can be ...

Neural tube defects

Pediatric Clinics of North America, 2004
Defects of development of the neural tube can result in a number of seemingly different malformations. Understanding the abnormal embryology helps one understand the malformations and their surgical treatments. The clinical presentations and the follow-up of these patients require attention to various end organs besides the nervous system.

The prevention of neural tube defects

Current Opinion in Obstetrics and Gynaecology, 1998
The prevention of neural tube defects is a complex problem. The genetic associations may ultimately allow the prepregnancy identification of women at high risk of a neural tube defect. Education of both the public and healthcare providers has been shown to increase awareness, but the majority of women do not take folic acid before and in the early part
