Linkage Position-Controlled Synthesis of Diverse Zirconium Metal-Organic Frameworks with Prominent Intrinsic Proton Conductivities.

Herein, by engineering the geometries of the organic linkers, two pyrrolo-pyrrole-based low-symmetry tetracarboxylate linkers (TAPPs) were successfully designed and subsequently used for the construction of two new zirconium-based metal-organic frameworks (Zr-MOFs) ( and ). The reduction of the linker symmetry arises from both the asymmetric pyrrolo-pyrrole core and the integration of both the - and -benzoate coordination groups on the linkers. Both MOFs are composed of 8-connected Zr nodes and 4-connected highly deformed TAPP linkers with the same topology, but distinct linker arrangements can be observed in two structures.

The results showed that the proportions of polyurethane （PU） and polyethylene （PE） were 17.57% and 15.

Correlates and influences of Chinese parental communication about the COVID-19 pandemic: The moderating role of parental burnout.

Despite evidence that parental communication about COVID-19 can have short-term benefits such as adolescents' increased health behaviors, less is known about the potential long-term associations between such communication and adolescent adjustment, as well as the family characteristics that facilitate such communication. Moreover, it is important to examine such processes beyond Western societies and broaden the understanding of parental communication in non-Western societies. To fill these gaps in the literature, a two-wave longitudinal study on Chinese families spanning 1 year during the pandemic (July 2020-July 2021) was conducted.

Developing a RecT-assisted endogenous CRISPR/SzCas9 system for precise genome editing in Streptococcus zooepidemicus.

Streptococcus zooepidemicus is the most commonly utilized strain for industrial-scale hyaluronic acid (HA) production due to its capacity to produce high-quality HA. However, the lack of efficient genetic manipulation approaches has significantly hindered the industrial application of this species. In this study, we developed a RecT-assisted endogenous CRISPR/SzCas9 system to enable markerless gene deletion, gene substitution, stop codon insertion, and iterative editing in the industrially significant strain S.

Utility of quantitative whole-body autoradiography (QWBA) and oxidative combustion (OC) analysis in the assessment of tissue distribution of [14C]Mefuparib (CVL218) in SD and LE rats.

Background: In tissue distribution studies of radiopharmaceuticals, quantitative whole-body autoradiography (QWBA) and oxidative combustion (OC) analysis are the two important methods that have not been compared using the same drug. Sprague-Dawley (SD) and Long-Evans (LE) rats, both of which are commonly used rodents in tissue distribution studies, have also not been compared using the same drug. Comparative studies are important for aiding the selection of appropriate experimental methods and animals.

Wogonin mitigates microglia-mediated synaptic over-pruning and cognitive impairment following epilepsy.

Background: Epilepsy, a neurological disorder characterized by recurrent abnormal neuronal discharges, leading to brain dysfunction and imposing significant psychological and economic burdens on patients. Microglia, the resident immune cells within the central nervous system (CNS), play a crucial role in maintaining CNS homeostasis. However, activated microglia can excessively prune synapses, exacerbating neuronal damage and cognitive dysfunction following epilepsy.

A new approach for endowing photocatalytic performance to biochar based on peryleneimide: Emphasizing the achievement of highly efficient degradation to RhB.

Having unique structural characteristics of biochar contributes great potential in photocatalysis, the preparation process complexity is still a great challenge for biochar-based photocatalysts. Based on this, this study proposes a new, simple, efficient, and flexible approach to preparing biochar-based photocatalysts by perylene diimide (GPC/PDI). The results showed that the hybridization between GPC and PDI was achieved by π-π stacking, which was reduced with increasing pyrolysis temperature, increased first and then decreased with increasing PDI content, and improved with enhanced solvent polarity.

The current research on ST elevation myocardial infarction (STEMI) patients has been mostly limited to Door-to-Balloon (D-to-B) time. This study aimed to compare the effects of different hospital admission modes to on the time metrics of patients undergoing primary percutaneous coronary intervention (PPCI). It also examined the effects of these modes on in-hospital mortality and other influencing factors.

The fecal microbiota of patients with primary biliary cholangitis (PBC) causes PBC-like liver lesions in mice and exacerbates liver damage in a mouse model of PBC.

The role of the gut microbiota in the occurrence and progression of primary biliary cholangitis (PBC) is not fully understood. First, the fecal microbiota of patients with PBC ( = 4) (PBC-FMT) or healthy individuals ( = 3) (HC-FMT) was transplanted into pseudo germ-free mice or 2OA-BSA-induced PBC models. The functions, histology and transcriptome of the liver, and microbiota and metabolome of the feces were analyzed.

Aptamer-RIBOTAC Strategy Enabling Tumor-Specific Targeted Degradation of MicroRNA for Precise Cancer Therapy.

MicroRNA (miRNA) molecules play crucial roles in a variety of diseases, making miRNA targeting a burgeoning field in medicinal chemistry. Ribonuclease targeting chimeras (RIBOTACs) present a compelling approach for RNA degradation. However, small molecule-based RIBOTAC requires an expensive and time-consuming screening process, and is difficult to directly target miRNA due to its short length lacking secondary structure.

Early infiltrating NKT lymphocytes attenuate bone regeneration through secretion of CXCL2.

Trauma rapidly mobilizes the immune response of surrounding tissues and activates regeneration program. Manipulating immune response to promote tissue regeneration shows a broad application prospect. However, the understanding of bone healing dynamics at cellular level remains limited.

The risk of viable but non-culturable (VBNC) enterococci and antibiotic resistance transmission during simulated municipal sludge composting.

Sludge composting is a sludge resource utilization method that can reduce pollutants, such as pathogens. Enterococci are regarded as more reliable and conservative indicators of pathogen inactivation than fecal coliforms, which are typically used as indicators of fecal pollution. Non-spore pathogenic bacteria may enter a viable but non-culturable (VBNC) state during composting, leading to residual risk.

Mitochondria-targeting peptide SS-31 attenuates ferroptosis via inhibition of the p38 MAPK signaling pathway in the hippocampus of epileptic rats.

Ferroptosis is a newly identified form of non-apoptotic regulated cell death (RCD) andplaysanimportantrole in epileptogenesis. The p38 mitogen-activated protein kinase (p38 MAPK) pathway has been confirmed to be involved in ferroptosis. The mitochondria-targeting antioxidant Elamipretide (SS-31) can reduce the generation of lipid peroxidation and the buildup of reactive oxygen species (ROS).
