An Engineering Porous Spherical Carbon Cathode for High-Energy Sodium-Ion Capacitor.

Sodium-ion hybrid capacitors (SICs) are emerging as promising devices that can balance energy and power output. However, the lack of a high-capacity cathode that can match the anode has limited its further application. In this work, we develop an efficient method to prepare spherical porous carbons (SPCs) with great specific surface area and narrow pore size distribution from coal-based humic acid via spray drying and a subsequent chemical activation process.

Detection of GSH with a dual-mode biosensor based on carbon quantum dots prepared from dragon fruit peel and the T-Hg(II)-T mismatch.

Glutathione (GSH) is commonly used as a diagnostic biomarker for many diseases. In this study, based on carbon quantum dots prepared from dragon fruit peel (D-CQDs) and the T-Hg(II)-T mismatch, a dual-mode biosensor was developed for the detection of GSH. This system consists of two single-stranded DNA (ssDNA).

The discrepancy of NH oxidation mechanism between SAPO-34 and Cu/SAPO-34.

The difference of NH oxidation mechanism over SAPO-34 and Cu-SAPO-34 was studied. XRD (X-ray diffraction), SEM (scanning electron microscopy) and H-TPR (H-temperature programmed desorption) were conducted to estimate the Cu species distribution. The quantity of individual Cu ions escalated with the elevation of silicon content in the Cu/SAPO-34 catalysts, leading to an enhancement in the activity of the NH-SCR (ammonia-selective catalytic reduction) process.

A Fluorescence Biosensor Based on Carbon Quantum Dots Prepared from Pomegranate Peel and T-Hg-T Mismatch for Hg Detection.

Mercury ions (Hg) can cause damage to human health, and thus, the study of the detection of Hg is extraordinarily important in daily life. This work reported a fluorescence biosensor for the detection of Hg. The key point of this strategy was that the fluorescence of carbon quantum dots made from pomegranate peel (P-CQDs) was quenched by hemin, and restored after G-quadruplex binding with hemin.

Construction of Prediction Model of Renal Damage in Children with Henoch-Schönlein Purpura Based on Machine Learning.

Objective: The children with Henoch-Schönlein purpura (HSP) may suffer from renal insufficiency, which seriously affects the life and health of the children. This study aims to construct a prediction model of Henoch-Schönlein purpura nephritis (HSPN).

Methods: A total of 240 children with HSP treated in dermatology and pediatrics in our hospital were selected.

N-doped graphene encapsulated MoSnanosphere composite as a high-performance anode for lithium-ion batteries.

MoSis widely used in lithium-ion batteries (LIBs) due to its high capacity (670 mAh g) and unique two-dimensional structure. However, the further application was limited of MoSas anode materials suffer from its volume expansion and low conductivity. In this work, N-doped graphene encapsulated MoSnanosphere composite (MoS@NG) were prepared and its unique sandwich structure containing abundant mesopores and defects can efficiently enhance reaction kinetics.

Influence of coracoglenoid space on scapular neck fracture stability: biomechanical study.

Background: The anatomical variation of the coracoglenoid space has the potential to influence the stability of scapular neck fractures. This paper aimed to investigate the mechanical mechanism underlying the influence of different coracoglenoid space types on scapular neck fractures by morphometric analysis and biomechanical experiments.

Methods: The morphology of 68 dried scapulae (left: 36; right: 32) was studied.

Improved window adaptive gray level co-occurrence matrix for extraction and analysis of texture characteristics of pulmonary nodules.

Background And Objective: Identifying benign and malignant pulmonary nodules is essential for the early diagnosis of lung cancer and targeted surgical resection. This study aimed to differentiate benign from malignant pulmonary nodules based on computed tomography (CT) plain scan texture analysis technique.

Methods: A total of 47 pulmonary nodules use the improved window adaptive gray level co-occurrence matrix (GLCM) algorithm to extract the texture characteristics of the area of interest.

Association of Bone Morphogenetic Protein (BMP)/Smad Signaling Pathway with Fracture Healing and Osteogenic Ability in Senile Osteoporotic Fracture in Humans and Rats.

BACKGROUND To investigate the effect of the BMP/Smad signaling pathway on fracture healing and osteogenic ability in senile osteoporotic fracture on humans and rats. MATERIAL AND METHODS Sixty-two patients and well-matched normal controls were enrolled for clinical observation. A rat model of senile osteoporotic fracture was established.

Hemodynamics of cerebral bridging veins connecting the superior sagittal sinus based on numerical simulation.

Background: The physiological and hemodynamic features of bridging veins involve wall shear stress (WSS) of the cerebral venous system. Based on the data of cadavers and computational fluid dynamics software pack, the hemodynamic physical models of bridging veins (BVs) connecting superior sagittal sinus (SSS) were established.

Results: A total of 137 BVs formed two clusters along the SSS: anterior group and posterior group.

17-Estradiol Promotes Islet Cell Proliferation in a Partial Pancreatectomy Mouse Model.

17-Estradiol (E2) is a multifunctional steroid hormone in modulating metabolism . Previous studies have reported that E2 could promote insulin secretion and protect cells from apoptosis. In this study, the partial pancreatectomy (PPx) model was used to study the role of E2 in islet cell proliferation.

Anatomic study of maximum intensity projection of the membranous labyrinth and the internal auditory meatus - MRI scan in 16 Chinese adults.

Conclusion: Three-dimensional reconstruction of maximum intensity projection (MIP) might document objectively, stereoscopically and directly the minute structures of the membranous labyrinth and internal auditory meatus. In this study, we establish magnetic resonance imaging (MRI) measurement criteria of the inner ear in Chinese adults.

Objective: The goal of this study was to provide an anatomic basis for otolosurgery and neurosurgery in Chinese adults.
