    Abstract Objective: The formation of blood clot, achieved through periapical bleeding or the use of peripheral venous blood, platelet-rich plasma (PRP) or platelet-rich fibrin (PRF), has been widely utilized in regenerative endodontic procedures (REPs). Except for inducing periapical bleeding, the scaffolds obtained from PRP, PRF, and venous blood are not derived from oral and maxillofacial tissues. In this case report, autologous blood clots from alveolar bone were described, which involved puncturing the maxillary terminal alveolar bone. The purpose of this case report was to assess the efficacy of the alveolar-derived blood clot in regenerative endodontic procedures in a mature permanent premolar.
    Methods: A mature premolar had a fractured central cusp, one of the developmental aberrations of tooth, without a proper treatment, resulting in chronic periapical lesion. To address this condition, REPs were employed, utilizing blood obtained through aspiration from the maxillary terminal alveolar bone aspiration.
    Result: Follow-up examinations of tooth #29 revealed the absence of clinical symptoms, a progressive resolution of a periapical lesion area and thickening of the root canal walls.
    Conclusion: This case demonstrated that blood clot obtained through paracentesis of the maxillary terminal alveolar bone could be successfully applied in REPs and has potential to manage periapical lesions. However, further and more clinical trials are required to verify the feasibility of the alveolar-derived blood clot in REPs and compare the outcome of alveolar-derived blood clot with currently used biological scaffolds.
    Clinical relevance: In comparison to PRP or PRF from peripheral venous blood, blood clots obtained via paracentesis of the maxillary terminal alveolar bone could be administrated by dentists, eliminating the need for reliance on professional nurses. The use of blood clots from alveolar bone could simplify the REPs in cases where periapical blood was insufficient to brim the root canals.

    Abstract Accurate quantitative information of the analytes in mass spectrometry imaging (MSI) is fundamental for determining the accurate spatial distribution, which can provide additional insight into the living processes, disease progression or the pharmacokinetic-pharmacodynamic mechanisms. However, performing a quantitative analysis in MSI is still challenging. This review focuses on the quantitation-related factors and recent advances in the strategies of quantitative MSI (q-MSI) of small molecules. The main quantitation-related factors are discussed according to the new investigations in recent years, including the regionally varied extraction efficiencies and ionization efficiencies, signal-concentration regression functions, and the repeatability of surface sampling/ionization methods. Newly developed quantitation strategies in MSI based on aforementioned factors are introduced, including new techniques in standard curve calibration with normalization to an internal standard, kinetic calibration, and chemometric methods. Different strategies for validating q-MSI methods are discussed. Finally, the future perspectives to q-MSI are proposed.

    Abstract It is currently unclear how sharpness discrimination ability is distributed across a wide range of edge sharpness and the effect of contact area on haptic perception. We 3D printed triangular prisms with various edge sharpness and half-edge widths in the full-scale range and conducted 2AFC tasks to gain the haptic threshold distribution. Results show that the distribution curves of the sharpness threshold and its contact area have a similar inflection point at 115°, implying a boundary between medium-low and high stimuli. It is also found that Weber fractions in the medium stimulus range follow Weber's Law and are consistent with previous studies but lower than the mean of Weber fractions in the high stimulus range. Besides, there is no significant difference in upper and lower thresholds in the medium-low stimulus range but a significant difference in the high stimulus range with the higher upper threshold. Variations in contact area do not affect sharpness discrimination ability when the half-edge width exceeds 2 mm. However, decreasing the half-edge width from 2 mm to 1 mm significantly reduces haptic sensitivity. Our findings offer preliminary evidence contributing to understanding haptic perception in edge sharpness discrimination, encompassing the properties of objects and object-individual interfaces.

    Abstract This collection of reviews aims to summarise our current understanding of a fundamental question: how do we deal with DNA damage? After identifying key players that are important for this process, we are now starting to reveal the dynamic organisation of detecting and repairing DNA damage. Reviews in this issue provide an update on the exciting research progress that is happening now in this field and also initiate discussion about future challenges and directions that we are heading to.

    Abstract The species with a strongly pubescent body with the genus name Capillogryllus by Xie, Zheng, and Liang in 2003 are reviewed. Capillogryllus has presently two species, Capillogryllus exilipalpis Xie & Zheng, 2003 (type specimen is a female), and Capillogryllus dolabripalpis Xie & Zheng, 2003 (type species), both of which are only known from China at this time. In Gyirong County, Tibet, we discovered a new species of this genus that is distinct from the two species mentioned above. Here, three species of Capillogryllus are described and illustrated.

    Abstract Coronavirus disease 19 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is affecting the world with a surge in cases. A variety of autoimmune diseases occur after SARS-CoV-2 infection or vaccination, of which IgG4-related disease (IgG4-RD) is an important type. IgG4-RD can involve multiple organs of the body. The ocular manifestation of IgG4-RD is called IgG4-related ophthalmic disease (IgG4-ROD). We herein report a patient diagnosed with IgG4-ROD. The patient developed ptosis and vision loss after SARS-CoV-2 vaccination, and the symptoms worsened after SARS-CoV-2 infection. After excluding other diseases like myasthenia gravis and Eaton-Lambert syndrome that may cause ptosis, the diagnosis of IgG4-ROD was confirmed by pathological examination. We discussed the predisposing factors, diagnosis and treatment of this patient to provide a more empirical and theoretical basis for clinical diagnosis and treatment. We conducted a literature review of previously reported cases of IgG4-RD following SARS-CoV-2 infection or vaccination. We retrieved a total of 9 cases, of which 5 developed symptoms after vaccination and 4 after infection. Demographic and clinical characteristics were summarized. In conclusion, our case represents the first case of proven IgG4-ROD after COVID-19 vaccination. We believe that IgG4-ROD and SARS-CoV-2 infection or vaccination are closely related, and the immune system disorder caused by SARS-CoV-2 infection or vaccination may be a key factor in the pathogenesis of IgG4-RD. But for now, there is no direct evidence that there is a causal relationship between SARS-CoV-2 infection or vaccination and IgG4-ROD, which still needs more research and exploration to confirm.
