Revolutionizing nanozymes: The synthesis, enzyme-mimicking capabilities of carbon dots, and advancements in catalytic mechanisms.

Nanozymes, a revolutionary category of engineered artificial enzymes based on nanomaterials, have been developed to overcome the inherent limitations of natural enzymes, such as the high cost associated with storage and their fragility. Carbon dots (CDs) have emerged as compelling candidates for various applications due to their versatile properties. Particularly noteworthy are CDs with a range of surface functional groups that exhibit enzyme-like behavior, combining exceptional performance with catalytic capabilities.

[Progress on chemical constituents and quality control of Bovis Calculus and its substitutes].

Bovis Calculus, a traditional medicine with the role of clearing away heat and detoxification, extinguishing wind to arrest convulsions, is often used for brain-cerebrovascular diseases. However, the quality control of Bovis Calculus and its substitutes has attracted much attention due to the scarcity of resources and limitations of use. Based on the evolution of the use of substitutes and the chemical composition as the entry point, this article reviews the quality control methods from the following three aspects.

Transcriptomic decoding of regional cortical vulnerability to major depressive disorder.

Previous studies in small samples have identified inconsistent cortical abnormalities in major depressive disorder (MDD). Despite genetic influences on MDD and the brain, it is unclear how genetic risk for MDD is translated into spatially patterned cortical vulnerability. Here, we initially examined voxel-wise differences in cortical function and structure using the largest multi-modal MRI data from 1660 MDD patients and 1341 controls.

[Improvement effect of Shegan Mahuang Decoction on rats with cold-induced asthma based on TRPV1/NRF-1/mtTFA pathway].

This study investigated the therapeutic effect of Shegan Mahuang Decoction(SGMHD) on cold-induced asthma in rats and explored its underlying mechanism. Seventy-two healthy male SD rats of specific pathogen free(SPF) grade were randomly divided into a blank group, a model group, a positive control group(dexamethasone, 0.4 mg·kg~(-1)), and low-, medium-, and high-dose SGMHD groups(3.

[Research progress on chemical constituents and pharmacological effects of Kaixin Powder and predictive analysis of its Q-markers].

Kaixin Powder is a classic prescription for invigorating Qi, nourishing the mind, and calming the mind. It has pharmacological effects of improving learning and memory ability, resisting oxidation, delaying aging, and promoting the differentiation and regeneration of nerve cells. It is mainly used in the modern clinical treatment of amnesia, depression, dementia, and other diseases.

[Research progress of Shegan Mahuang Decoction and predictive analysis on its Q-markers].

Shegan Mahuang Decoction has been used in clinical practice for thousands of years, and is a classical formula for treating asthma and other respiratory diseases, with the effects of ventilating lung, dispersing cold, and relieving cough and asthma. This paper summarized the history, clinical application and mechanism of Shegan Mahuang Decoction, and predicted its quality markers(Q-markers) based on the "five principles" of Q-markers. The results suggested that irisflorentin, tectoridin, tectorigenin, irigenin, ephedrine, pseudoephedrine, asarinin, methyleugenol, shionone, epifriedelanol, tussilagone, 6-gingerol, trigonelline, cavidine, schizandrin, and schizandrin B could be used as Q-markers of Shegan Mahuang Decoction, which provided a basis for the quality control and subsequent research and development of Shegan Mahuang Decoction.

[Review of chemical composition, pharmacological effects, and clinical application of Salviae Miltiorrhizae Radix et Rhizoma and prediction of its Q-markers].

Salviae Miltiorrhizae Radix et Rhizoma is a Chinese herbal medicine that promotes blood circulation to remove blood stasis, nourishes blood to tranquilize the mind, and cools blood to disperse carbuncles. Salviae Miltiorrhizae Radix et Rhizoma has microcirculation-improving, blood vessel-dilating, atherosclerosis-preventing, anti-inflammatory, anti-tumor, and blood pressure-and blood lipid-lowering activities. As research progresses, the chemical composition, pharmacological effect, and clinical application of Salviae Miltiorrhizae Radix et Rhizoma have attracted much attention.

Gene Is Associated With Clinical Response to SNRIs in a Local Chinese Han Population.

The relation between the () gene and major depressive disorder (MDD) has been studied in a local Chinese Han population. MDD is associated with the rs2032582 () and rs1128503 () single-nucleotide polymorphisms (SNPs) of but not with rs1045642, rs2032583, rs2235040, and rs2235015. This study aims to explore the potential correlations of therapeutic responses with selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) in a local Chinese Han population.

BAFF enhances B-cell-mediated immune response and vaccine-protection against a very virulent IBDV in chickens.

Infectious bursal disease (IBD) is an acute, highly infectious and immunosuppressive disease caused by IBDV, which specifically targets destruction of B cells in the bursa of Fabricius. B-cell activating factor belonging to the TNF family (BAFF, also called BLyS, TALL-1, THANK, or zTNF4) is an important factor for B-cell proliferation and survival. Here we demonstrate that human soluble BAFF (hsBAFF) may enhance humoral immune response by elevating B lymphocyte activity of secretion of immunoglobulin (Ig) such as IgA, IgM and IgG in chickens immunized or unimmunized with an inactivated IBDV vaccine from a very virulent strain.

[Effects of splenic B lymphocyte proliferation and response and intracellular Ca2+ of hsBAFF in mice].

Aim: To investigate effects of hsBAFF synthesized in Escherichia coli on spleen B lymphocyte immune response and its intracellular free Ca2+ ([Ca2]i]) signaling in mice.

Methods: Twenty ICR mice, half males-half females, were chosen and randomly divided into a normal control group (n=10) and a hsBAFF treatment group (n-10). The mice in hsBAFF treatment group were given abdominal cavity injection of hsBAFF solution which was diluted with phosphate buffered saline (PBS) at dosage of 0.

Immunological effects of refolded human soluble BAFF synthesized in Escherichia coli on murine B lymphocytes in vitro and in vivo.

The B cell activating factor of the TNF family (BAFF, also known as BLyS, TALL-1, THANK, and zTNF4) is an important survival factor for B lymphocytes. Our previous study has demonstrated that the final purified material of human soluble BAFF (refolded hsBAFF) synthesized in Escherichia coli is biologically active in a validated induced human B lymphocyte proliferation bioassay. In this study, the administration of refolded hsBAFF to isolated mouse B lymphocytes and mice was carried out to study the immunological effects of hsBAFF on in vitro and in vivo B lymphocytes.
