Multispectral detection technology captures characteristic spectral information across various wavebands, exhibiting substantial application potential. However, most currently reported multispectral photodetectors rely on intricate dual- or multi-junction structures, severely limiting material thickness, doping concentration, and band alignment design, thereby impeding widespread adoption. In this study, a bias-tunable multispectral photodetector featuring a straightforward single-junction design is introduced.

In this study, ultrasonic technology was combined with microwave vacuum drying technology to explore the impacts of different coupling methods (ultrasonic pretreatment and ultrasonic coupled drying) on the structural characterisation and physicochemical properties of shiitake mushroom (Lentinus edodes) polysaccharides at different ultrasonic powers (0, 120 and 280 W), and compared with hot air drying (HAD). The results demonstrated that the monosaccharide composition of Lentinus edodes polysaccharides (LEPs) remained largely unaltered after treatment with various drying methods, although significant disparities in molar content were observed. Air ultrasound combined with microwave vacuum drying (USMVD) at 280 W ultrasound power resulted in LEPs with higher contents of total sugars (8.

Article Synopsis
  • The research investigates how iron oxide magnetic nanoparticles (MNP Fe3O4) combined with gambogic acid (GA-MNP Fe3O4) affect colorectal cancer (CRC), showing an enhanced antitumor effect against CRC cells.
  • GA targets a protein called RORB, which when activated by GA, helps to inhibit CRC metastasis, while knocking down RORB reduces the efficacy of GA-MNP Fe3O4 in combating cancer spread.
  • RORB also promotes the expression of another protein, EMILIN1, and increasing EMILIN1 levels can counteract the negative effects of RORB knockdown, further aiding in the reduction of CRC metastasis.

Article Synopsis
  • - The study examined how non-exercise estimated cardiorespiratory fitness (eCRF) affects mortality rates in hypertensive adults, showing that better eCRF is linked to lower risks of death from all causes and cardiovascular diseases but not from cancer.
  • - Data from 27,437 participants indicated that for each 1 metabolic equivalent increase in eCRF, there were significant decreases in all-cause mortality (HR 0.78) and CVD mortality (HR 0.79), with a stronger effect seen in females than in males.
  • - The findings highlight the importance of eCRF in health outcomes for hypertensive individuals and suggest that further research is required to explore these relationships across different populations.

Given the surpassing of the Shockley-Quiesser efficiency limit in conventional p-n junction photovoltaic effect, bulk photovoltaic effect (BPVE) has garnered significant research interest. However, the BPVE primarily focuses on a narrow wavelength range, limiting its potential applications. Here we report a giant infrared bulk photovoltaic effect in tellurene (Te) for broad-spectrum neuromodulation.

Hepatocellular carcinoma (HCC) is a primary liver cancer with high pathogenicity and extremely poor prognosis. The role of circular RNAs (circRNAs) in HCC carcinogenesis and progression remains to be determined. Based on the analysis of HCC-related databases, as well as the expression analysis and identification of 25 HCC patient tissues and HCC cell lines, we found that the hsa_circ_0031431 (circCOCH) is significantly highly expressed in HCC tissues and cell lines.

Background: Radioactive iodine-125 (I) microparticle therapy is a new type of internal radiation therapy that has shown unique advantages in the treatment of malignant tumors, especially hepatocellular carcinoma. Patients with hepatocellular carcinoma frequently experience portal vein embolism, which exacerbates the difficulty and complexity of treatment. I particles, used in local radiotherapy, can directly act on tumor tissue and reduce damage to surrounding healthy tissue.

Background: Controversy exists as to the optimal treatment approach for ostial left anterior descending (LAD) or ostial left circumflex artery (LCx) lesions. Drug-coated balloons (DCB) may overcome some of the limitations of drug-eluting stents (DES). Therefore, we investigated the security and feasibility of the DCB policy in patients with ostial LAD or ostial LCx lesions, and compared it with the conventional DES-only strategy.

Cryopreservation of semen renders artificial insemination easier and cheaper compared to use of fresh semen. However, the cellular oxidative stress, toxicity of cryoprotectants, and osmotic imbalance may lead to a decline in semen quality and fertilization ability during the process of cryopreservation. L-carnitine and L-proline have been demonstrated to possess effective antioxidant properties in cryopreservation, with the latter also exhibiting excellent permeability and thus being utilized as a permeable cryoprotectant in the field.
