Effect of soil conditioner on alleviating saline-alkali stress damage of maize.

Soil conditioners are efficacy in ameliorating saline-alkali soils and fostering crop growth. To explore the effect and physiological mechanism of soil conditioner on improving the adaptability of maize to saline-alkali stress, we conducted a field randomized block experiment in Liuzhong Village, Pingluo County, Ningxia Province in 2022. We investigated the variations of antioxidant capacity, key enzyme activities and photosynthetic fluorescence properties of maize induced by soil conditioners under saline-alkali stress, with "Xianyu 1255" maize as the experimental material under four treatments: T(no conditioner, control), T(humic acid), T(microsilica fume + wood vine-gar solution), T(humic acid + wood vinegar solution + microsilica fume).

Unraveling the Diffusion MRI-Based Glymphatic System Alterations in Children with Rolandic Epilepsy.

Rationale And Objectives: Although dysfunction of the glymphatic system in adult epilepsy has been extensively studied, there is a lack of research on the changes in this system during childhood development, particularly in children with Rolandic epilepsy (RE). This study aimed to investigate the changes in diffusion MRI measures related to the glymphatic function in children with RE.

Materials And Methods: A total of thirty-eight children with RE and thirty-six demographically matched healthy children were enrolled in the study.

Structure-function interrelationships and associated neurotransmitter profiles in drug-naïve benign childhood epilepsy with central-temporal spikes patients.

Objectives: To explore the interrelationships between structural and functional changes as well as the potential neurotransmitter profile alterations in drug-naïve benign childhood epilepsy with central-temporal spikes (BECTS) patients.

Methods: Structural magnetic resonance imaging (sMRI) and resting-state functional MRI data from 20 drug-naïve BECTS patients and 33 healthy controls (HCs) were acquired. Parallel independent component analysis (P-ICA) was used to identify covarying components among gray matter volume (GMV) maps and fractional amplitude of low-frequency fluctuations (fALFF) maps.

Individual-based morphological brain network changes in children with Rolandic epilepsy.

Objective: To investigate the local cortical morphology and individual-based morphological brain networks (MBNs) changes in children with Rolandic epilepsy (RE).

Methods: Based on the structural MRI data of 56 children with RE and 56 healthy controls (HC), we constructed four types of individual-based MBNs using morphological indices (cortical thickness [CT], fractal dimension [FD], gyrification index [GI], and sulcal depth [SD]). The global and nodal properties of the brain networks were analyzed using graph theory.

An efficient biosensor using a functionalized microneedle of CuO-based CoCu-LDH for glucose detection.

Glucose detection with small and micro volume sampling has recently received increasing attention in monitoring personal health. Herein, a cauliflower-type cluster of CuO nanoparticles (NPs) was directly deposited on the tip surface of a stainless steel acupuncture needle electrode (ANE) by electrochemical deposition, and then this pre-formed cuprous basis was used to further prepare the neatly arranged CoCu-layered double hydroxide (CoCu-LDH) nanosheets that interconnected to form nano-sized pores in the range from 100 to 500 nm. The microstructure and spectral characteristics of the surface modification materials were comprehensively characterized by FE-SEM, EDS, XRD, FT-IR and TEM.

Structural and functional changes in drug-naïve benign childhood epilepsy with centrotemporal spikes and their associated gene expression profiles.

Benign epilepsy with centrotemporal spikes (BECTS) is a common pediatric epilepsy syndrome that has been widely reported to show abnormal brain structure and function. However, the genetic mechanisms underlying structural and functional changes remain largely unknown. Based on the structural and resting-state functional magnetic resonance imaging data of 22 drug-naïve children with BECTS and 33 healthy controls, we conducted voxel-based morphology (VBM) and fractional amplitude of low-frequency fluctuation (fALFF) analyses to compare cortical morphology and spontaneous brain activity between the 2 groups.

Disrupted functional connectivity patterns of the left inferior frontal gyrus subregions in benign childhood epilepsy with centrotemporal spikes.

Background: Benign epilepsy with centrotemporal spikes (BECTS) is one of the most common pediatric epileptic syndromes. Recent studies have shown that BECTS can lead to significant language dysfunction. Although research supports the role of the left inferior frontal gyrus (LIFG) in BECTS, it is unclear whether the subregions of the LIFG show different change patterns in patients with this syndrome.

Abnormalities of hemispheric specialization in drug-naïve and drug-receiving self-limited epilepsy with centrotemporal spikes.

Purpose: Self-limited epilepsy with centrotemporal spikes (SLECTS) is a pediatric benign epilepsy but often accompanied by subsequent (in adulthood) functional changes such as language, which are thought to have distinct areas of hemispheric lateralization and functional differentiation. This study aimed to explore hemispheric specialization measured by resting-state functional magnetic resonance imaging (rs-fMRI) functional connectivity in drug-naïve and drug-receiving SLECTS.

Methods: Hemispheric specialization was quantified in three groups of children, including 21 drug-naïve patients (DNP) with SLECTS, 34 drug-receiving patients (DRP) with SLECTS and 36 demographically matched typical development (TD).

Abnormal percent amplitude of fluctuation and functional connectivity within and between networks in benign epilepsy with centrotemporal spikes.

Background: Benign epilepsy with centrotemporal spikes (BECTS) is one of the most common childhood epilepsy syndromes. The neural basis of BECTS is still poorly understood. This study aimed to further investigate the possible neural mechanisms of BECTS by comparing percent amplitude of fluctuation (PerAF) of resting-state functional magnetic resonance imaging (RS-fMRI) signal of each brain voxel and connectivity within and between related networks in children with BECTS and healthy controls (HCs).

Prediction of Communication Impairment in Children With Bilateral Cerebral Palsy Using Multivariate Lesion- and Connectome-Based Approaches: Protocol for a Multicenter Prospective Cohort Study.

Background: Bilateral cerebral palsy (BCP) is the most common type of CP in children and is often accompanied by different degrees of communication impairment. Several studies have attempted to identify children at high risk for communication impairment. However, most prediction factors are qualitative and subjective and may be influenced by rater bias.

Connectome-based prediction of brain age in Rolandic epilepsy: a protocol for a multicenter cross-sectional study.

Background: Rolandic epilepsy (RE) is a common pediatric idiopathic partial epilepsy syndrome. Children with RE display varying degrees of cognitive impairment. In epilepsy, age-related neuroanatomic and cognitive changes differ greatly from those observed in the healthy brain, and may be defined as accelerated brain aging.

Surface-based morphometry study of the brain in benign childhood epilepsy with centrotemporal spikes.

Background: The study aimed to explore cortical morphology in benign childhood epilepsy with centrotemporal spikes (BECTS) and the relationship between cortical characteristics and age of onset and intelligence quotient (IQ).

Methods: Cortical morphometry with surface-based morphometry (SBM) was used to compare changes in cortical thickness, gyrification, sulcal depth, and fractal dimension of the cerebral cortex between 25 BECTS patients and 20 healthy controls (HCs) with two-sample -tests [P<0.05, family-wise error (FWE) corrected].

Teratoma of the adrenal gland: clinical experience and literature review.

Teratoma originates from pluripotent cells of two or more than two germ cell layers, and most of them are benign. Teratomas are found in the ovaries and testes. Retroperitoneal teratoma is rare, especially adrenal teratoma.

Angiomyolipoma of the adrenal gland: clinical experience and literature review.

Angiomyolipomas, a type of benign mesenchymal tumor originating from perivascular epithelioid cells, are composed of mature adipose tissue, smooth muscle, and thick-walled vessels. With fewer than 20 cases reported in English literature, adrenal angiomyolipoma is extremely rare. In these cases, the patient is usually asymptomatic and the tumor is found incidentally.
