Single-nucleus RNA sequencing uncovers metabolic dysregulation in the prefrontal cortex of major depressive disorder patients.

Major depressive disorder (MDD) is a widespread psychiatric condition, recognized as the third leading cause of global disease burden in 2008. In the context of MDD, alterations in synaptic transmission within the prefrontal cortex (PFC) are associated with PFC hypoactivation, a key factor in cognitive function and mood regulation. Given the high energy demands of the central nervous system, these synaptic changes suggest a metabolic imbalance within the PFC of MDD patients.

Case report: A cyclic neutropenia patient with mutation accompanied by hemophagocytic lymphohistiocytosis.

Many inborn errors of immunity may accompany secondary hemophagocytic lymphohistiocytosis (HLH), a condition typically characterized by impaired cytotoxic T and NK cell function. A considerable proportion of HLH cases also stem from chronic granulomatosis with phagocytic dysfunction. However, the development of secondary HLH in patients with severe congenital neutropenia (SCN) or cyclic neutropenia (CyN) with abnormal phagocytic cell counts has been less frequently reported.

Reflection-type orientation-switchable optical differentiator exemplified by the BK7-MoS interface.

Optical differential operation is an ultra-fast edge information extraction technology that enables identifying the image features, whereas current optical differentiators mainly operate along one or two differential orientations and is incompetent for switching the differential orientation. A reflection-type orientation-switchable optical differentiator is proposed and the BK7-MoS interface is used as an example to analyze the edge detection performance. Theory suggests that there are dual modulation methods, one is tuning the incident polarization angle with a Brewster incident angle, and the other one is altering the incident angle with a nearly vertical incident polarization angle.

An efficient and successful outcome after haematopoietic stem cell transplantation in a patient with an LPS-responsive beige-like anchor gene mutation.

Lipopolysaccharide (LPS)-responsive beige ankyrin (LRBA) gene mutations were first reported as the cause of immunodeficiency syndromes and autoimmunity in 2012. The majority of LRBA patients have multiple organ system involvement and a complex clinical phenotype. Herein we present a comprehensive account on the disease progression and transplantation procedure in a patient with LRBA deficiency who exhibited progressive autoimmune disease symptoms along with recurrent pulmonary infections since the age of 6 years old.

Successful Immune Reconstitution in a Patient with a TYK2 Deficiency after Allogeneic Stem Cell Transplantation from Unrelated Donors.

A boy with primary immunodeficiency, caused by a tyrosine kinase 2 (TYK2) mutation, presented with immune defects and a lifelong history of severe infections. Our aim was to determine whether allogeneic hematopoietic stem cell transplantation (HSCT) could restore the patient's immune defenses and reduce susceptibility to infection. In the absence of a suitable HLA-matched blood relative to act as a donor, the patient received an allogeneic HSCT from unrelated donors.

Influence of Cold Wave Diversities on Thermal Stress and Thermal Fatigue Life of Asphalt Mixture.

Apart from low-temperature cracking, asphalt pavement may also suffer from thermal fatigue cracking. To clarify the impact of cold waves on the thermal fatigue performance of asphalt mixtures, the typical atmospheric temperature characteristics of different regions in China from 2012 to 2019 were analyzed, and the frequency of cold waves in these regions was determined. The viscoelastic parameters of an asphalt mixture are determined through an indirect tensile relaxation test.

Ultra-high order mode-assisted optical differentiator for edge detection with high tunability.

An optical spatial differentiator based on the photonic spin Hall effect (PSHE) with high tunability is presented. By utilizing the characteristics of ultra-high order modes in the symmetrical metal cladding waveguide, the Fresnel reflection coefficient spectrum exhibits a narrow peak width and low trough at the resonant incident angles, resulting in high sensitivity to changes in the incident angle-induced spatial shift caused by the PSHE (the highest (| / |)/ value can reach 10). After polarization transformation and extinction, the output field demonstrates differential operation with respect to the input field.

Spinal cord decellularized matrix scaffold loaded with engineered basic fibroblast growth factor-overexpressed human umbilical cord mesenchymal stromal cells promoted the recovery of spinal cord injury.

Spinal cord injury (SCI) will lead to irreversible damage of sensory and motor function of central nervous system, which seriously affects patient's quality of life. A variety of nerve engineering materials carrying various stem cells and cell growth factors had used to promote the repair of SCI, but they could not mimic the actual matric niche at spinal cord to promote cell proliferation and differentiation. Thus, developing novel biomaterial providing better niche of spinal cord is a new strategy to treat the severe SCI.

Zero-Dimensional Hybrid Cd-Based Perovskites with Broadband Bluish White-Light Emissions.

Recently, low-dimensional organic-inorganic hybrid metal halide perovskites acting as single-component white-light emitting materials have attracted extensive attention, but most studies concentrate on hybrid lead perovskites. Herein, we present two isomorphic zero-dimensional (0D) hybrid cadmium perovskites, (HMEDA)CdX (HMEDA=hexamethylenediamine, X=Cl (1), Br (2)), which contain isolated [CdX ] anions separated by [HMEDA] cations. Under UV light excitation, both compounds display broadband bluish white-light emission (515 nm for 1 and 445 nm for 2) covering the entire visible light spectrum with sufficient photophysical stabilities.

Broadband White-Light Emission in One-Dimensional Organic-Inorganic Hybrid Silver Halide.

In the past few decades, organic-inorganic hybrid metal halides acting as single-component white light emission diodes (LEDs) have attracted extensive attentions, but most of the studies concentrate on the low-dimensional lead perovskites. Here, by using the nontoxic silver as optically active metal center, a series of hybrid silver halides based on one-dimensional structures were constructed and realized broadband white light emission. Compounds [HDABCO][AgX(DABCO)] (X = Br (), I ()) feature one-dimensional [AgX(DABCO)] structures charged balanced by [HDABCO] cations.

Herein, we have proposed a sensitive UDG assay based on the terminal deoxynucleotidyl transferase (TdT)-assisted formation of fluorescent copper nanoclusters (CuNCs). In this study, a uracil-containing stem-loop DNA substrate is rationally designed with its 3'-end blocked with 2', 3'-dideoxycytosine (ddC).

Rolling circle extension-actuated loop-mediated isothermal amplification (RCA-LAMP) for ultrasensitive detection of microRNAs.

Rolling circle amplification (RCA) is an elegant and well-recognized isothermal nucleic acid amplification mechanism that has been widely used for the detection of various kinds of genetic biomarkers. However, traditional RCA is a linear signal amplifying mechanism so that the amplification efficiency is generally not satisfactory. Herein, we rationally combine RCA with efficient loop-mediated isothermal amplification (LAMP) to establish a rapid and ultrasensitive RCA-LAMP method for the detection of microRNAs (miRNAs).
