Efficacy and Prognosis of Hyperbaric Oxygen as Adjuvant Therapy for Neonatal Hypoxic-Ischemic Encephalopathy: A Meta-Analysis Study.

Background: Preclinical and clinical evidence suggests that hyperbaric oxygen therapy (HBOT) may benefit newborns. The effectiveness of HBOT for neonatal hypoxic-ischemic encephalopathy (HIE) remains controversial. We conducted a meta-analysis to evaluate the efficacy and prognosis of HBOT in neonates with HIE.

[Discussion on automated external defibrillator configuration optimization strategy of rapidly developing city: a case study of Bao'an, Shenzhen].

Objective: To explore the automated external defibrillator (AED) configuration optimization strategy in line with the characteristics of the rapidly developing cities by analyzing the actual coverage of AED in Bao'an District based on the real world data of out-of-hospital cardiac arrest (OHCA) in Bao'an District, Shenzhen City.

Methods: The data of cardiac arrest database registered in Bao'an District of Shenzhen City from March 1, 2019 to February 29, 2020 were included in a retrospective observational study. The AED coverage of public and non-public areas was analyzed by calculating the minimum distance between the occurrence place of each OHCA event and the nearest AED.

The conventional treatment group was given conventional treatment, and the low molecular heparin group was given low molecular heparin based on conventional treatment.

[Experience in the construction of social first aid service system: the on-demand training of "Baoan Mode"].

At present there is a lack of standardized first-aid training mode in China. It is an important issue in the construction of social first aid system that how to arrange the first aid training and popularization in a planned and reasonable way according to the limited training resources. Under the guidance of Shenzhen City Baoan District government, the "Baoan Mode" of social emergency grid management has been promoted and achieved good results.

Prenatal diagnosis of Duchenne muscular dystrophy revealed a novel mosaic mutation in Dystrophin gene: a case report.

Background: Duchenne muscular dystrophies (DMDs) are X-linked recessive neuromuscular disorders with malfunction or absence of the Dystrophin protein. Precise genetic diagnosis is critical for proper planning of patient care and treatment. In this study, we described a Chinese family with mosaic DMD mutations and discussed the best method for prenatal diagnosis and genetic counseling of X-linked familial disorders.

Incorporating polyoxometalates and organic ligands to pursue 3d-4f heterometallic clusters: a series of {CrLn} clusters stabilized by phthalic acid and [SiWO].

By introduction of trilacunary Keggin-type polyoxometalate to the hydrothermal reaction system of Cr, Ln and phthalic acid, a series of novel {CrLn} heterometallic clusters with the formula Cs[CrLn(μ-O)(μ-O)(CHO)(HO)](HSiWO)Cl·23HO (1-Ln, Ln = Ce, Pr, Nd) and [CrLn(μ-O)(μ-O)(CHO)(HO)](HSiWO)Cl·18HO (2-Ln, Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er) have been obtained. Single-crystal structural analyses show that 1-Ln and 2-Ln constitute the first cases of Cr-Ln heterometallic clusters stabilized by inorganic polyoxometalate anions and organic ligands. Optical spectra studies demonstrate that 1-Ln and 2-Ln are narrow-gap semiconductors with band gaps of about 1.

A Series of Banana-Shaped 3d-4f Heterometallic Cluster Substituted Polyoxometalates: Syntheses, Crystal Structures, and Magnetic Properties.

Four seven-nuclearity 3d-4f heterometallic cluster {FeLnO} substituted polyoxometalates (HPz)KFeLn(μ-O)(B-α-GeWO)(GeWO)· xHO (1-Ln, Pz = piperazine, Ln = Tb, Dy, Ho, Er for x = 27, 25, 25, 24, respectively) have been hydrothermally prepared and structurally characterized by single-crystal X-ray diffraction, powder X-ray diffraction, infrared spectrometry, thermogravimetric analyses, elemental analyses, and electrospray ionization mass spectrometry. Single-crystal X-ray diffraction analyses revealed that 1-Ln contain an unprecedented banana-shaped polyanion constructed from an iron-lanthanide heterometallic {FeLnO} cluster, two trilacunary {B-α-GeWO} units, and one hexalacunary {GeWO} fragment. The magnetic susceptibility surveying proved the presence of antiferromagnetic coupling in 1-Ln.

Immunocytochemical localization of cholinergic amacrine cells in the bat retina.

The purpose of this study was to localize the cholinergic amacrine cells, one of the key elements of a functional retina, in the retina of a microbat, Rhinolophus ferrumequinum. The presence and localization of choline acetyltransferase-immunoreactive (ChAT-IR) cells in the microbat retina were investigated using immunocytochemistry, confocal microscopy, and quantitative analysis. These ChAT-IR cells were present in the ganglion cell layer (GCL) and inner part of the inner nuclear layer (INL), as previously reported in various animals.

Types and density of calbindin D28k-immunoreactive ganglion cells in mouse retina.

Single-cell injection after immunocytochemistry is a reliable technique for classifying neurons by their morphological structure and their expression of a particular protein. The aim of the present study was to classify the morphological types of calbindin D28k-immunoreactive retinal ganglion cells in the mouse using single-cell injection after immunocytochemistry, to estimate the density of calbindin D28k-immunoreactive retinal ganglion cells in the mouse retina. Calbindin D28k is an important calcium-binding protein that is widely expressed in the central nervous system.

Immunocytochemical localization of the calcium-binding proteins calbindin D28K, calretinin, and parvalbumin in bat visual cortex.

It is a common misconception that bats are blind, and various studies have suggested that bats have visual abilities. The purpose of this study was to investigate the cytoarchitecture of calbindin D28K (CB)-, calretinin (CR)-, and parvalbumin (PV)-immunoreactive (IR) neurons in the bat visual cortex using immunocytochemistry. The highest density of CB- and PV-IR neurons was located in layer IV of the visual cortex.

Localization of Nitric Oxide Synthase-containing Neurons in the Bat Visual Cortex and Co-localization with Calcium-binding Proteins.

Microchiroptera (microbats) is a suborder of bats thought to have degenerated vision. However, many recent studies have shown that they have visual ability. In this study, we labeled neuronal nitric oxide synthase (nNOS)-the synthesizing enzyme of the gaseous non-synaptic neurotransmitter nitric oxide-and co-localized it with calbindin D28K (CB), calretinin (CR), and parvalbumin (PV) in the visual cortex of the greater horseshoe bat (Rhinolophus ferrumequinum, a species of microbats).
