- Addressing the need for modulated spin configurations is crucial, as they serve as the foundational building blocks for next-generation spintronics, particularly in atomically thin structures and at room temperature. In this work, we realize intrinsic ferromagnetism in monolayer flakes and tunable ferro-/antiferromagnetism in (Fe0.56Co0.44)5GeTe2 antiferromagnets. Remarkably, the ferromagnetic ordering (≥1 L) and antiferromagnetic ordering (≥4 L) remain discernible up to room temperature. The TC (∼310 K) of the monolayer flakes sets a record high for known exfoliated monolayer van der Waals magnets. Within the framework of A-type antiferromagnetism, a notable odd-even layer-number effect at elevated temperatures (T = 150 K) is observed. Of particular interest is the strong ferromagnetic order in even-layer flakes at low temperatures. The intricate interplay among magnetic field strength, layer number, and temperature gives rise to a diverse array of phenomena, holding promise not only for new physics but also for practical applications.

- Background: Osteoarthritis (OA) is a common chronic degenerative joint disease characterized by articular cartilage degeneration and synovitis. CircRNAs are increasingly being recognized as functional endogenous RNAs with a stable structure and high tissue specificity. Recent studies have shown that some circRNAs may be involved in the initiation and progression of OA and that there is differential expression of circRNAs in chondrocytes in vitro isolated from patients with OA.Purposes: In this study, we aimed to determine if circRNA levels in the peripheral blood of Chinese Han patients with OA would be diagnostic based on the previous in vitro studies.Methods: We collected peripheral blood samples from 25 patients suffering from OA and 25 healthy controls and measured hsa_circ_0032131_CBC1 RNA levels through quantitative RT-PCR (qRT-PCR). The statistical basis for evaluating the diagnostic value was to calculate the area under the receiver operator characteristic (ROC) curve.Results: The results of the qRT-PCR for hsa_circ_0032131_CBC1 were consistent with those of the microarray analysis. The ROC curve shows that hsa_circ_0032131 holds diagnostic value for OA (0.8455, p < 0.01).Conclusions: Our research indicates that differentially expressed circRNAs may be involved in the development of OA and could be used diagnostically.

- Objective: This research aims to explore differentially expressed circRNA between OA and KBD and potential diagnostic biomarkers.Methods: Total RNA was extracted from 5 pairs of KBD and OA knee joint cartilage specimens, and the expression of circRNAs was analyzed by Chip Scanning Analysis. The microarray data was verified by quantitative polymerase chain reaction (qRT-PCR). CircRNA-miRNA network was constructed to predict targeting microRNAs of circRNA genes. Peripheral blood samples from 25 KBD patients and 25 OA patients were collected for verification by qRT-PCR. Diagnostic value was evaluated by the area under the receiver operator characteristic (ROC) curve.Results: A total of 1627 circRNAs were differentially expressed between OA and KBD. Five bone and joint disease-related circRNAs were chosen for qRT-PCR validation. The difference in expression profile of hsa_circRNA_0020014 was confirmed by qRT-PCR, and its circRNA-miRNA regulation network was set up. The ROC curve demonstrated that hsa_circ_0020014_CBC1 in peripheral blood could distinguish patients with KBD and OA.Conclusion: The expression profiles of circRNA were significantly different between OA and KBD. hsa_circRNA_0020014 is a potential biomarker for differential diagnosis between these two diseases.
