Abstract	Carrageenan (CR) is a renewable polysaccharide material for packaging application due to its good film-forming property, but its use can be limited by the water solubility. In this research, CR hydrogels were modified by quaternary ammonium surfactants with different length of hydrocarbon tails (n, 8≦n≦16) by adsorption method and waterproof films were obtained after drying. The composition and charge interaction of composite films was confirmed by FTIR. Both thermogravimetric analysis and energy dispersive spectrometer indicated that the surfactant ions replaced K

Abstract	Introduction and hypothesis: The objective was to evaluate the efficacy of pessaries in the treatment of stage IV pelvic organ prolapse (POP) and identify the influencing factors. Methods: One hundred and fifty-seven patients with stage IV symptomatic POP were admitted to the hospital for pessary fitting. A successful pessary fitting was defined as a patient fitted with a pessary at the initial fitting in whom use continued 2 weeks later. The rates of successful pessary fitting, patient satisfaction, remission of prolapse and urinary symptoms, and the occurrence of factors associated with successful pessary fitting were calculated and predictors of appropriate pessary type selection were analyzed. Results: A total of 130 patients with stage IV POP had a successful pessary fitting (82.8%). The satisfaction rate associated with the two types of pessaries was more than 90%. The success rate among patients undergoing a ring pessary fitting trial was 44.6%, and 84.3% of the patients were self-managed. Prolapse symptoms significantly improved in 90% of cases, and urinary symptoms improved in 58-93% of cases from baseline. The number of vaginal deliveries, history of hysterectomy and vaginal introitus/total vaginal length (TVL) ratio were independent risk factors associated with unsuccessful pessary fitting. Conclusion: For patients with stage IV POP, the successful fitting rate is as high as 80% or more. More vaginal deliveries, a history of hysterectomy, and a larger vaginal introitus/TVL ratio (ratio >0.6) were predictors of unsuccessful pessary fitting.

Abstract	Phenotype D-- is associated with severe hemolytic transfusion reactions and hemolytic disease of the fetus and newborn. It is typically caused by defective RHCE genes. In this study, we identified a D-- phenotype proband and verified RH phenotypes of other six family members. However, inconsistent results between the phenotypic analysis and Sanger sequencing revealed intact RHCE exons with no mutations in the D-- proband, but the protein was not expressed. Subsequent Oxford Nanopore Technologies whole-genome sequencing of the proband revealed an inversion with ambiguous breakpoints in the intron 2 and intron 7 and copy number variation loss in the RHCE gene region. Given that the RHCE gene is highly homologous to the RHD gene, we conducted a comprehensive analysis using Pacific Biosciences long-read target sequencing, Bionano optical genome mapping, and targeted next-generation sequencing. Our findings revealed that the proband had two novel recombinant RHCE haplotypes, RHCECe(1-2)-D(3-10) and RHCECe(1-2)-D(3-10)-Ce(10-8)-Ce(3-10), with clear-cut breakpoints identified. Furthermore, the RH haplotypes of the family members were identified and verified. In summary, we made a novel discovery of hereditary large inversion and recombination events occurring between the RHD and RHCE genes, leading to lack of RhCE expression. This highlights the advantages of using integrated genetic analyses and also provides new insights into RH genotyping.

Abstract	As a typical and promising application of the Internet of things, smart grid will play an increasingly important role in the future power system. However, security and privacy issues in smart grids need to be addressed. If the user’s electricity consumption is transmitted in plaintext, the data may be used by some illegal users. At the same time, malicious users may send false data such that the control center makes a wrong power resource scheduling. In addition, efficiency issues should be taken into account in Internet of things applications. To overcome these challenges, an efficient and privacy-preserving certificateless data aggregation scheme is proposed for Internet of things–enabled smart grids. The confidentiality and integrity of data can be guaranteed, and the identity of users can be hidden in our scheme. In particular, if some users have malicious behaviors, they will be tracked. The proposed scheme can resist replay attacks, modification attacks, and impersonation attacks. In the process of collecting data, computation of encryption and signature generation do not need expensive bilinear pairings. Furthermore, batch verification is used to improve efficiency of verification. It is demonstrated that the security, privacy, and efficiency issues in smart grid are addressed based on security and performance analysis.

Abstract	Blockchain technology has been widely used in many fields. However, the proof of work (PoW) problem in the mining process of mobile devices requires a large amount of computing resources and energy consumption, which brings huge challenges to mobile devices. Mobile edge computing (MEC) can effectively solve the above problems, allowing mobile devices to offload tasks to edge servers to relieve the pressure of limited computing resources on mobile devices. Nonorthogonal multiple access (NOMA) is good at improving spectrum efficiency, so that the system can accommodate more users. In this paper, we propose a new NOMA-based MEC-enabled blockchain framework. Under the conditions of a given task execution deadline, the decision of offloading, local computing resource allocation, user clustering and admission control, and transmit power control is jointly optimized to minimize the total cost of the system. Since the problem is hard to solve, we decouple it into subproblems for low-complexity solutions. First, we propose two heuristic algorithms to obtain the binary offloading decision and user association, and then closed-form solutions of local resource allocation and transmit power control are obtained under the required delay constraints. Simulation results show that our proposed algorithms perform good in cost reduction compared with other baseline algorithms.

Abstract	Rumination is closely related to ruminant's health and welfare, so it is very important to monitor rumination. Rumination monitoring equipment based on chewing and swallowing audio is easy to be affected by ambient noise, equipment based on acceleration sensor is not easy to monitor number of cuds and other information, equipment based on video monitoring has high cost and is easy to be affected by weather and other cows, while equipment based on chewing pressure can accurately record the chewing pressure of dairy cows, and use related processing technology to obtain the number of cuds and other information. In the related research, the peak value and interval of masticatory pressure peak in time domain were used to identify rumination. In view of the problem that the standard of pressure peak was not well defined due to the different head size and masticatory strength of different age and different breed cows, this paper proposed a method to identify the number of rumination, duration of rumination and number of cuds of cows by using standard deviation and noseband pressure signal frequency spectrum. The accurate and stable frequency spectrum range of rumination noseband pressure signal was obtained by frequency spectrum analysis, and the interference of feeding noseband pressure signal to rumination noseband pressure signal was eliminated by using standard deviation. Compared with the direct observation, the results showed that the recognition accuracy of the method proposed in this paper were 100%, 94.2% and 94.45% for the number of rumination, duration of rumination and number of cuds respectively, and the average absolute errors were 0, 2.0029% and 2.5623% respectively, which showed that the method can accurately identify the rumination information of dairy cows.

Abstract	This study examines if heme biosynthesis-associated iron metabolism is regulated in pulmonary arteries by endothelin-1 (ET1) potentially through modulating cartilage oligomeric matrix protein (COMP) availability. Our studies in organoid-cultured endothelium-rubbed bovine pulmonary arteries (BPAs) observed COMP depletion by siRNA or hypoxia increases NOX2 and superoxide and depletes mitochondrial SOD2. ET1 also increases superoxide in a manner that potentially impairs mitochondrial heme biosynthesis. In this study, organoid culture of BPA with ET1 (10 nM) increases superoxide in the mitochondrial matrix and extramitochondrial regions associated with COMP depletion, and COMP (0.5 μM) inhibited these superoxide increases. As mitochondrial matrix superoxide could impair heme biosynthesis from protoporphyrin IX (PpIX) by decreasing Fe

Abstract	Background: Coronavirus disease 2019 (COVID-19) caused by the Omicron variant occurred in Shanghai, China, but its clinical characteristics and virology have not been comprehensively described. Methods: This retrospective cohort study included adult inpatients (≥18 years) diagnosed with COVID-19 at Changhai Hospital. Laboratory and clinical data were obtained from electronic medical records to investigate the clinical characteristics of COVID-19 and the variations in the patients' laboratory indexes were examined. Results: The symptoms of COVID-19 caused by the Omicron variant were relatively mild. Upper respiratory tract specimens yielded higher positive detection rates than lower respiratory tract and intestinal specimens. Peak COVID-19 viral load was reached at the time of admission; quantification cycle (Cq) values increased to approximately 35 after 8.54 days. Conclusions: Virus replication and shedding are rapid in Omicron-positive patients; COVID-19 in these patients is characterized by acute onset, mild symptoms, and fast recovery. Older patients and those with more severe disease demonstrate prolonged virus shedding. Routine hematological indexes can reveal disease severity and help clinically evaluate the patient's condition.
