Carbohydrazide-induced low triggering potential electrochemiluminescence from perylene-based metal-organic framework for bioanalysis.

3,4,9,10-perylenetetracarboxylic acid (PTCA), as a typical polycyclic aromatic hydrocarbon (PAH), has become a special electrochemiluminescence (ECL) luminophore by virtue of its high quantum yield and excellent photoelectric properties. However, its aggregation-caused quenching (ACQ) effect and high ECL potentials (usually greater than -1.5 V vs Ag/AgCl) limited its application.

RBCK1 enhances antiviral response through promoting K63-linked polyubiquitination of IRF7 in Carassius auratus var. Pengze.

Ubiquitination is a widely occurring reversible post-translational modification process in cells. RANBP2-type and C3HC4-type zinc finger-containing 1 (RBCK1) is a kind of E3 ubiquitin ligase. It regulates various biological functions, including protein degradation and kinase signaling pathways in mammals.

Modified Pulsatilla decoction ameliorates ulcerative colitis by affecting gut microbiota and metabolite profiles.

To investigate the therapeutic effects of a specific modified Pulsatilla decoction (MPD) on ulcerative colitis (UC) in mice, 32 male Balb/c mice were randomly assigned to four groups: Control, Model, High-dose (H-dose), and Low-dose (L-dose), with eight mice per group. All groups except the Control group were administered 3% dextran sulfate sodium (DSS) in their drinking water for 7 days to induce acute UC. The H-dose group and L-dose group mice were gavaged, respectively, with different concentrations of MPD, while the Control group and Model group received the same amount of steriled water by gavage.

Uncovering the potential functions of lymph node metastasis-associated aberrant methylation differentially expressed genes and their association with the immune infiltration and prognosis in bladder urothelial carcinoma.

Background: Bladder urothelial carcinoma (BLCA) is a malignant tumor of the urinary system. This study aimed to explore the potential role of lymph node metastasis-associated aberrant methylation differentially expressed genes (DEGs) in BLCA.

Methods: CHAMP and limma packages were used to identify lymph node metastasis-associated aberrant methylation DEGs.

Prediction of pathological staging and grading of renal clear cell carcinoma based on deep learning algorithms.

Objective: Deep learning algorithms were used to develop a model for predicting the staging and grading of renal clear cell carcinoma to inform clinicians' treatment plans.

Methods: Clinical and pathological information was collected from 878 patients diagnosed with renal clear cell carcinoma in the Department of Urology, Peking University First Hospital. The patients were randomly assigned to the test set (n = 702) or the verification set (n = 176).

Effect of roscovitine pretreatment for increased utilization of small follicle-derived oocytes on developmental competence of somatic cell nuclear transfer embryos in pigs.

The objective of this study was to evaluate the effect of roscovitine pretreatment on the number of matured oocytes per ovary available for somatic cell nuclear transfer (SCNT) and their developmental competence. Irrespective of reproduction status (prepuberty/puberty), the average number of small follicles per ovary (19.3/17.

Comparative transcriptomic analysis of two Cucumis melo var. saccharinus germplasms differing in fruit physical and chemical characteristics.

Background: Hami melon (Cucumis melo var. saccharinus) is a popular fruit in China because of its excellent taste, which is largely determined by its physicochemical characteristics, including flesh texture, sugar content, aroma, and nutrient composition. However, the mechanisms by which these characteristics are regulated have not yet been determined.

Hypodermin A improves survival of skin allografts.

Background: Hypodermin A (HA) is a serine esterase that degrades complement, a key element of the innate immune system. Immunosuppressive properties of HA have previously been studied in vitro. However, such properties have not been fully demonstrated in vivo.

Generation of GGTA1 biallelic knockout pigs via zinc-finger nucleases and somatic cell nuclear transfer.

Genetically modified pigs are valuable models of human disease and donors of xenotransplanted organs. Conventional gene targeting in pig somatic cells is extremely inefficient. Zinc-finger nuclease (ZFN) technology has been shown to be a powerful tool for efficiently inducing mutations in the genome.

The effect of the number of transferred embryos, the interval between nuclear transfer and embryo transfer, and the transfer pattern on pig cloning efficiency.

To improve the efficiency of producing cloned pigs, we investigated the influence of the number of transferred embryos, the culturing interval between nuclear transfer (NT) and embryo transfer, and the transfer pattern (single oviduct or double oviduct) on cloning efficiency. The results demonstrated that transfer of either 150-200 or more than 200NT embryos compared to transfer of 100-150 embryos resulted in a significantly higher pregnancy rate (48 ± 16, 50 ± 16 vs. 29 ± 5%, p<0.

Molecular detection of Anaplasma phagocytophilum in Ixodid ticks in Hebei Province, China.

A total of 3696 Ixodid ticks, collected from Hebei Province, China, were examined by a nested polymerase chain reaction for the presence of Anaplasma phagocytophilum. Forty-three (15.4%) of 280 pools tested, including 39 (14.

Detection of spotted fever group Rickettsia in Haemaphysalis longicornis from Hebei Province, China.

DNA samples from 737 tick pools, representing 6,850 Haemaphysalis longicornis and 51 Dermacentor nuttalli collected from Hebei Province, China, were analyzed by polymerase chain reaction (PCR) for the presence of spotted fever group Rickettsia. Fifty (6.9%) of 724 H.
