Abstract	As one of the most fundamental thiol compounds in the human body, cysteine (Cys) is involved in maintaining redox balance. Abnormal Cys levels can lead to various diseases. In this work, we successfully synthesized a fluorescent probe (CTBA) that can specifically detect Cys using acrylate as the reaction site, and CTBA has met the selectivity and anti-interference for Cys detection under optimized conditions. The linear range for Cys detection is between 0.05 and 100 μM and the detection limit is 0.0381 μM. Finally, this probe is used to detect the Cys content in three bovine serum samples and the test results are satisfactory.

Abstract	Objective: To compare the effectiveness of the long head of the biceps tendon (LHBT) with or without proximal amputation after arthroscopic rotator cuff repair in the treatment of repairable rotator cuff tear with LHBT injury. Methods: The clinical data of 68 patients with LHBT injury combined with supraspinatus tendon tear who met the selection criteria between January 2016 and June 2020 were retrospectively analyzed. According to whether the proximal end of LHBT was cut off or not after arthroscopic rotator cuff repair, they were divided into LHBT fixation without cutting group (group A, 32 cases) and LHBT fixation with cutting group (group B, 36 cases). There was no significant difference in gender, age, operating side, preoperative supraspinatus tear width, Constant-Murley shoulder function scale, University of California Los Angeles (UCLA) score, and visual analogue scale (VAS) score between the two groups ( Results: There was no significant difference in operation time between the two groups ( Conclusion: In arthroscopic rotator cuff repair, whether the proximal structure of LHBT is cut off or not after LHBT fixation can effectively improve the symptoms of patients and promote the recovery of shoulder joint function. Compared with preserving the proximal structure of LHBT, cutting the proximal structure of LHBT after LHBT fixation has more obvious pain relief within 6 months, and the latter had better stability above the shoulder joint.

Abstract	Calmodulin (CaM) binds to a linker between the oxygenase and reductase domains of nitric oxide synthase (NOS) to regulate the functional conformational dynamics. Specific residues on the interdomain interface guide the domain-domain docking to facilitate the electron transfer in NOS. Notably, the docking interface between CaM and the heme-containing oxygenase domain of NOS is isoform specific, which is only beginning to be investigated. Toward advancing understanding of the distinct CaM-NOS docking interactions by infrared spectroscopy, we introduced a cyano-group as frequency-resolved vibrational probe into CaM individually and when associated with full-length and a bi-domain oxygenase/FMN construct of the inducible NOS isoform (iNOS). Site-specific, selective labeling with p-cyano-L-phenylalanine (CNF) by amber suppression of CaM bound to the iNOS has been accomplished by protein coexpression due to the instability of recombinant iNOS protein alone. We introduced CNF at residue 108, which is at the putative CaM-heme (NOS) docking interface. CNF was also introduced at residue 29, which is distant from the docking interface. FT IR data show that the 108 site is sensitive to CaM-NOS complex formation, while insensitivity to its association with the iNOS protein or peptide was observed for the 29 site. Moreover, narrowing of the IR bands at residue 108 suggests the C≡N probe experiences a more limited distribution of environments, indicating side chain restriction apparent for the complex with iNOS. This initial work sets the stage for residue-specific characterizations of structural dynamics of the docked states of NOS proteins.

Abstract	The potential release capacity of arsenic (As) from sediment was evaluated under a high level of exogenous organic matter (EOM) with both bioreactive and chemically reactive organic matters (OMs). The OMs were characterized by FI, HIX, BIX, and SUVA254 fluorescence indices showing the biological activities were kept at a high level during the experimental period. At the genus level, Fe/Mn/As-reducing bacteria (Geobacter, Pseudomonas, Bacillus, and Clostridium) and bacteria (Paenibacillus, Acidovorax, Delftia, and Sphingomonas) that can participate in metabolic transformation using EOM were identified. The reducing condition occurs which promoted As, Fe, and Mn releases at very high concentrations of OM. However, As release increased during the first 15–20 days, followed by a decline contributed by secondary iron precipitation. The degree of As release may be limited by the reactivity of Fe (hydro)oxides. The EOM infiltration enhances As and Mn releases in aqueous conditions causing the risk of groundwater pollution, which could occur in specific sites such as landfills, petrochemical sites, and managed aquifer recharge projects.

Abstract	Myocardial ischemia-reperfusion (MI/R) injury is a complication in vascular reperfusion therapy for MI, occurring in approximately 60% of patients. Ferroptosis is an important process in the development of MI/R cardiac lesions. Transferrin receptor 1 (TfR1), a marker of ferroptosis, corresponds to the changes in MI/R cardiac lesions and is expected to be a biomarker for detecting MI/R-induced ferroptosis. However, the noninvasive

Abstract	The potential risk of multiple contaminants mobilization from sediment was evaluated under the infiltration of reactive organic matter (OM) during groundwater recharge. Significant NH₄-N, PO₄³⁻, As, Fe, and Mn release were observed which show elevated peaks in the initial stage (0–19 d) and declines afterwards until reach quite low and stable content (20–37 d). When re-oxidize with SO₄²⁻ (38–65 d), the reducing condition is stimulated to release more Fe and Mn however no As, NH₄-N and PO₄³⁻. The microbial reductive Fe oxides dissolution is the main driving force for NH₄-N, PO₄³⁻, As, Fe, and Mn release. The NH₄-N and PO₄³⁻ release was attributed by passive mobilization from Fe/Mn oxides due to its dissolution. The cation exchange also works significantly on NH₄⁺ release while desorption works on PO₄³⁻ as well. Microorganism responses to the infiltration reactive OM and further impacts the mobilization of multiple contaminants. The precipitation of secondary Fe/Mn minerals accompanied by co-precipitation and/or re-absorption lower down their aqueous levels. However, this aqueous contamination risk was hidden in solid reactive secondary minerals when oxidizer like SO₄²⁻ perturbs the recurrence of Fe and Mn contamination occurs. This shows the perennial release of nutrients and trace elements should be paid attention in areas with reactive OM infiltration followed by redox/groundwater chemistry fluctuations, potentially in hyporheic zone of river/lake, managed aquifer recharge zone, etc.
