Published: March 2022

Plants have long been considered as a basis of medicines for different indigenous cultures around the globe. They continue as a prominent source of important phytoconstituents which exhibit significant biological activities. In this study, we performed the phytochemical screening, estimation of total phenolic and flavonoids, antioxidants, and antimicrobial activities of the stem bark of Beilschmiedia roxburghiana Nees using different solvents. The total phenolic and total flavonoid contents ranged from 106.73 ± 1.62 mg GAE/g and 99.32 ± 0.66 mg QE/g (methanol extract) to 65.59 ± 1.79 mg GAE/g and 29.98 ± 0.90 mg QE/g (n-hexane extract), respectively. The maximum 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity with a half-maximal inhibitory concentration (IC50) of 39.86 ± 3.69 μg/mL was observed for methanol extract followed by aqueous (IC50 = 43.55 ± 6.16 μg/mL), ethyl acetate (IC50 = 44.30 ± 5.88 μg/mL), dichloromethane (IC50 = 71.50 ± 4.70 μg/mL), and the lowest activity was observed for n-hexane extract. The disc diffusion method revealed that the ethyl acetate extract exhibited relatively higher activity against Salmonella typhi (ZOI = 13 mm), and moderate activities against Shigella sonnei, Acinetobacter baumannii, Klebsiella pneumoniae, and Staphylococcus aureus (ZOI = 12 mm). The methanol and aqueous extracts showed nearly parallel and the n-hexane and dichloromethane extracts exhibited mild antibacterial activities. The results indicated that the polarity index of the extracting solvents amplified the biological activities of the extract. The study is helpful to support the validity of the traditional application of the plant as natural medicine.

Authors: Isa Hasan M. A. , Alfayez Fatema
Published: March 2022

Background and Objectives. Gastrointestinal (GI) endoscopy is a medical field that has been evolving in the last decades. Innovative advances in pediatric endoscopy led to more accurate diagnosis of various GI diseases. This study aimed to assess the appropriateness of endoscopic procedures’ indications and to evaluate the diagnostic and therapeutic yield of pediatric GI endoscopy, considering the limitations to access this facility. Material and Methods. Retrospective, cross-sectional, and analytical chart review was performed for children who underwent GI endoscopy at Salmaniya Medical Complex, Bahrain, from 1995 to 2020. Demographic data, endoscopic indications, and findings were collected and compared. Results. Of 1,111 patients, 1,101 (99.1%) were included in the study. 589 (53.6%) patients were males. Median age at the time of endoscopy was 8 (interquartile range 3, 11) years. 1534 endoscopies were performed (1193 upper GI endoscopies (UGIE) and 341 colonoscopies) in 1296 sessions. The mean number of endoscopies per year was

). Ratio between UGIE to colonoscopy was 3.5 : 1. Median number of endoscopies per patient was one, ranging from one to eight procedures. 1153 (89%) sessions were diagnostic, and 143 (11.0%) were therapeutic. Main endoscopic indication was chronic abdominal pain (451 (40.9%) patients) followed by upper GI bleeding (302 (27.4%) patients). Overall positive yield was 68.1% (716/1052 procedures). Endoscopic yield varies according to the type of procedure (

). Colonoscopy alone gave a higher yield (82.6%, 38/46 procedures) compared to combined procedures (75.4%, 141/187) and UGIE alone (65.6%, 537/819). Conclusions. This study emphasizes a careful selection of the type of endoscopic procedures, based on the expected endoscopic yield, to diagnose and treat pediatric GI diseases. In patients with chronic abdominal pain, endoscopy should be reserved as a second-line tool to avoid unnecessary use of invasive procedures.

Published: March 2022

Cardiovascular disease is one of the most common diseases in the modern world, which, if diagnosed early, can greatly reduce the damage to the patient. Diagnosis of heart disease requires great care, and in some cases, the process can be disrupted by human error. Machine learning methods, especially data mining, have gained international acceptance in almost all aspects of life, especially the prediction of heart disease. On the other hand, datasets related to heart patients have many biological features that most of these features do not have a direct impact on diagnosis. By removing redundant features from the dataset, in addition to reducing computational complexity, the accuracy of heart patients’ predictions can also be increased. This paper presents a density-based unsupervised approach to the diagnosis of abnormalities in heart patients. In this method, the basic features in the dataset are first selected based on the filter-based feature selection approach. Then, the DBSCAN clustering method with adaptive parameters has used to increase the clustering accuracy of healthy instances and to determine abnormal instances as cardiac patients. Partition clustering methods suffer from the selection of the number of clusters and the initial central points and are very sensitive to noise. The DBSCAN method solves these problems by creating density-based clusters, but the selection of the neighborhood radius threshold and the number of connected points in the neighborhood remains unresolved. In the proposed method, these two parameters are selected adaptively to achieve the highest accuracy for the diagnosis and prediction of heart patients. The results of the experiments show that the accuracy of the proposed method for predicting heart patients is approximately 95%, which has improved in comparison with previous methods.

Published: March 2022

Lung transplant recipients experience a high rate of invasive pulmonary aspergillosis infections, for which voriconazole is the treatment of choice. We report a patient who developed voriconazole-induced myositis that relapsed after one dose of isavuconazole. Our patient was a 38-year-old man who received a single sequential lung transplantation and liver transplantation because of end-stage cystic fibrosis. He presented to our emergency room with acute pain in both forearms at 3 weeks after voriconazole was initiated for invasive pulmonary aspergillosis infection. Levels of voriconazole were normal during the course of therapy. After stopping voriconazole, the symptoms decreased but relapsed after one dose of isavuconazole. Other causes of muscle pain and inflammation were excluded. Magnetic resonance imaging of both arms showed muscle edema in both arms, including involvement of the fascia, consistent with myositis. There were no signs of necrosis. Isavuconazole was discontinued, and the corticosteroid dose was temporarily increased, with rapid resolution of all complaints. Our patient is the fourth reported case of voriconazole-induced myositis, and the first whose symptoms relapsed after initiating isavuconazole.

Authors: Ye Tielin
Published: March 2022

Objective. To study the molecular targets and mechanisms of Dayuan Decoction in the treatment of fever. Methods. The traditional Chinese medicine system pharmacological database and analysis platform (TCMSP) was used to search for the main active components and action targets of Dayuan Decoction. The GeneCards database was used to retrieve fever-related gene targets. The common gene targets were obtained by selecting the intersection of the action targets of the main active components of Dayuan Decoction and the fever-related gene targets using a Wayne diagram. Cytoscape 3.7.2 software was used to construct the drug active component action target network diagram. The protein-protein interaction PPI network of coacting targets was constructed using the STRING database. David data were used for Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses of common gene targets. Results. A total of 89 main active components and 832 acting gene targets of Dayuan Decoction were screened, of which 50 were common gene targets of Dayuan Decoction and fever, including apoptosis regulatory factor Bel (BCL2L1), interleukin 6 (IL-6), interleukin 10 (IL-10), and tumor necrosis protein 53 (TP53). A total of 47 GO and 59 KEGG enrichment entries were obtained using GO and KEGG enrichment analyses, involving the cancer pathway, hypoxia-inducible factor 1 (HIF-1) signaling pathway, and mitogen-activated protein kinase (MAPK) signaling pathway. Conclusion. Dayuan Decoction has multitarget regulation characteristics and a multifaceted role in the treatment of fever.

Published: March 2022

EMs is a kind of benign disease with certain malignant behaviors. The adhesion, invasive growth, and angiogenesis of ectopic endometrial cells are the pathological basis of EMs occurrence, but its etiology and pathogenesis have not been completely illustrated yet. In our research, we aim to investigate the role of miR‐363 in the pathogenesis of endometriosis. Real‐time quantitative PCR was used to detect the expression of miR‐363 before and after ESC/NSC transfection. CCK‐8, flow cytometry, and transwell assay were used to detect the effect of the miR‐363 expression on cell proliferation, apoptosis, and invasion. The effects of the miR‐363 expression on the contents of Fas/APO‐1 and ICAM‐1 in cell culture supernatant were detected by ELISA. qRT‐PCR and WB assay were used to detect the effects of the miR‐363 expression on the mRNA and protein expression levels of ICAM‐1, MMP‐7, and VEGF in ESC. The increased expression of miR‐363 could inhibit the proliferation and invasion of ESC, promote apoptosis, and inhibit the secretion of FAS/APO‐1 and ICAM‐1. The knockdown expression of miR‐363 promoted proliferation and invasion of NSC, inhibited apoptosis, and promoted secretion of FAS/APO‐1 and ICAM‐1. VCAM‐1, VEGF, and MMP‐7 were detected in ESCs before transfection. The protein expression level was higher than that of NSCs. Compared with pretransfection, the protein levels of VCAM‐1, VEGF, and MMP‐7 in the M‐363 group were significantly downregulated. The downregulated expression of miR‐363 was associated with a stronger cell proliferation ability, a lower cell apoptosis rate, and a stronger ESC. Migration is associated with invasiveness, proliferation, angiogenesis, and immune escape. The low expression of miR‐363 promotes endogenesis through posttranscriptional regulation of target genes VCAM‐1, MMP‐7, and VEGF. The differential expression of miR‐363 between ESC and NSC may be an important factor in the many biological differences between ESC and NSC.

Published: March 2022

In this paper, an aerostatic bearing model in the form of microorifice annular array is designed to explore the static performance of aerostatic bearing when the orifice diameter and working air film thickness are of the same order of magnitude. Firstly, the simulation model of the new bearing is established, the pressure distribution of the bearing gas film under the influence of the orifice diameter is analyzed by the CFD method, and the performance of the aerostatic bearing is compared with the traditional toroidal throttling method with the orifice diameter of 0.1 mm; at the same time, the effects of air supply pressure, orifice diameter, and orifice number on the static performance of the bearing under different air film thickness are analyzed; finally, a new bearing is developed, and the simulation results are verified by the experimental test. The results show that when the orifice diameter and the air film thickness are of the same order of magnitude, the maximum stiffness of the aerostatic bearing is significantly improved and the microporous throttled aerostatic bearing is more suitable for the field of high stiffness. The greater the air supply pressure, the greater the bearing capacity and stiffness of the bearing. The number of orifices has an effect on improving the bearing capacity of the bearing, but when the number of orifices is large, the effect will become less obvious. This study can provide a new theoretical reference for the design of aerostatic bearing.

Published: March 2022

The use of machine learning for seismic interpretation is a growing area of interest for researchers. Manual interpretation demands time and specialized effort. The use of machine learning model will expedite the process. The Convolutional Neural Networks (CNNs) are a class of deep learning algorithms used for images. In this paper, seismic facies segmentation using encoder-decoder architecture of CNNs is proposed. The proposed method filled the gap using a multimodel approach for seismic interpretation. The novelty of the model is that it is not limited to the current dataset and semantic segmentation models. The encoder-decoder architecture input and output size is the same, and it allows the labelling of each pixel of the image. Four models are trained on the open-sourced F3 block Netherlands dataset.

were extracted from the data. Data augmentation is used in two of the models to increase the data size for better model learning. Results of individual models and their ensemble are compared. Ensemble is performed by taking the average of the probabilities of the classes obtained from the trained models. Ensemble gave the superior results. Seven classes are segmented with a global pixel accuracy (GPA) of 98.52%, mean class accuracy (MCA) of 96.88%, and mean intersection over union (MIoU) of 93.92%.

Social media networking is a prominent topic in real life, particularly at the current moment. The impact of comments has been investigated in several studies. Twitter, Facebook, and Instagram are just a few of the social media networks that are used to broadcast different news worldwide. In this paper, a comprehensive AI-based study is presented to automatically detect the Arabic text misogyny and sarcasm in binary and multiclass scenarios. The key of the proposed AI approach is to distinguish various topics of misogyny and sarcasm from Arabic tweets in social media networks. A comprehensive study is achieved for detecting both misogyny and sarcasm via adopting seven state-of-the-art NLP classifiers: ARABERT, PAC, LRC, RFC, LSVC, DTC, and KNNC. To fine tune, validate, and evaluate all of these techniques, two Arabic tweets datasets (i.e., misogyny and Abu Farah datasets) are used. For the experimental study, two scenarios are proposed for each case study (misogyny or sarcasm): binary and multiclass problems. For misogyny detection, the best accuracy is achieved using the AraBERT classifier with 91.0% for binary classification scenario and 89.0% for the multiclass scenario. For sarcasm detection, the best accuracy is achieved using the AraBERT as well with 88% for binary classification scenario and 77.0% for the multiclass scenario. The proposed method appears to be effective in detecting misogyny and sarcasm in social media platforms with suggesting AraBERT as a superior state-of-the-art deep learning classifier.

Published: March 2022

Yak is a unique species of cattle that is adapted to the harsh natural environment of the Qinghai-Tibet Plateau. Research on the function of the yak rumen is limited to animal experiments, and the cell molecular mechanism is very limited. The high cost of isolation and culture of adult yak rumen epithelial cells (YRECs), low success rate, and limited cell life limit the scope of long-term physiological functions and nutrient absorption mechanisms of yak rumen epithelium in vitro studies. This study aimed to explore the isolation and immortal culture methods of primary YRECs and establish a new cell line model for studying cell molecular mechanisms. The human telomerase reverse transcriptase gene (hTERT) and simian virus 40 large T antigen (SV40T) were transferred into primary YDECs using mammalian gene expression lentiviral vectors. The immortalized cell line (SV40T-YREC-hTERT) retains the morphological and functional characteristics of primary cells. The epithelial cell marker protein cytokeratin 18 of the immortalized cell lines was positive, and the cell proliferation and karyotype were normal. The SV40T and hTERT genes were successfully transferred into immortalized cell lines and maintained high expression. Simultaneously, the immortalized cell lines had normal function of short-chain fatty acid (SCFA) transport and absorption, and the immortalized yak rumen epithelial cell lines were successfully established. In addition, the transepithelial electrical resistance value gradually increased with culture time, and the permeability of epithelial cells decreased by culturing epithelial cells in Transwell culture chambers. Transmission electron microscopy demonstrated the submicroscopic structure of cells in the integrity barrier model and established the YREC barrier model in vitro.
The Expression, Prognostic Value, and Immunological Correlation of MCEMP1 and its Potential Role in Gastric Cancer
Authors: Huang Pu , Liu Yawen , Jia Baoqing
Published: March 2022

Purpose. Gastric cancer (GC) is a lethal cancer with a poor 5-year relative survival, which requires a new research perspective. Our study aims to explore the biological impact of the mast cell-expressed membrane protein 1 (MCEMP1) in GC, which includes its expression and potential biological functions. Methods. The expression of MCEMP1 was assessed through public databases. The GO, KEGG, and GESA analyses were conducted to explore the biofunction of MCEMP1. And ssGSEA was used to analyze the infiltration of the immune cells for MCEMP1. The proliferation, migration, and invasion of GC cells were analyzed through CCK8, colony-forming, wound healing, Transwell, and Western blot assay. Results. The expression of MCEMP1 was higher in GC tissues. Further, we found a close relationship between MCEMP1 and poorer prognosis of gastric cancer by prognostic analysis. The functional analysis showed that MCEMP1 is involved in immune, inflammation, and metabolism-related pathways. The ssGSEA analysis indicated MCEMP1 mRNA expression was associated with immune infiltration of multiple immune cells. In cellular experiments, the invasion and metastasis of gastric cancer cells could be promoted by regulating the rise of MCEMP1 expression. Western blot analysis showed that regulation of MCEMP1 expression can affect EMT-related protein expression and that NF-κB expression is involved in this process. Conclusion. MCEMP1 shows a potential value for the prognosis in GC. And, abnormal expression of MCEMP1 in GC is correlated with tumor immune cell infiltration. In in vitro experiments, MCEMP1 can affect the proliferation, migration, and invasion of GC cells by regulating EMT, in which TLR4/NOD2/NF-κB was involved.
A Hybrid Multiobjective Optimization Based on Nondominated Sorting and Crowding Distance, with Applications to Wave Energy Converters
Authors: Saveca John , Sun Yanxia , Wang Zenghui
Published: March 2022

Multiobjective evolutionary algorithm based on decomposition (MOEA/D) has attracted a lot of attention since it can handle multiobjective problems (MOP) with a complicated Pareto front. The procedure involves decomposing a MOP into single subproblems, which are eventually optimized simultaneously based on the MOP neighborhood information. However, the MOEA/D strategy tends to produce a distributed optimization that is not of good quality in some problems with complex Pareto optimal front, such as problems with a long tail and sharp peak, common in real-world situations. This paper proposes an improved MOEA/D to enhance the distributed optimization quality and minimize its complexity while accelerating the optimization to get a better solution. The improved method is achieved by incorporating a Hybrid Differential Evolution/Particle Swarm Optimization algorithm and a hybrid operator based on nondominated sorting and crowding distance algorithm. This incorporation takes place in the mutation generator and initial population part of the original MOEA/D algorithm. Simulations and comparisons are carried out based on some MOP benchmark functions to verify the proposed method’s performance. The experimental results show that the proposed method achieves better performance compared to other algorithms. Furthermore, the proposed method is also applied to optimize the multiobjective wave energy converter model to maximize power per year and minimize cost per unit power.

Authors: Zhang Lin , Lin Weihao , Yang Zhenlin , Li Renda , Gao Yibo , He Jie
Published: March 2022

Pulmonary sarcomatoid carcinoma (PSC) is an unconventional non-small-cell lung cancer (NSCLC) that is currently managed under guidelines used for conventional NSCLC and has poor survival. Surgery is the optimal choice for resectable PSC, and the prevalence of mutations in this type of tumor laid the foundation for novel systemic therapies such as targeted therapy and immunotherapy. PSC is resistant to chemotherapy and radiotherapy, and the effects of the 2 therapies are controversial. Targeted therapies have been reported to confer survival benefits, and savolitinib, an oral selective MET tyrosine-kinase inhibitor, has been approved in metastatic patients with MET exon 14 skipping mutations. Expression and positive rate of programmed death ligand 1 in PSC are high; our previous research has also revealed a high mutational burden and a T-cell-inflamed microenvironment of PSC. Correspondingly, immune checkpoint inhibitors have shown preliminary antitumor effects (overall response rates of 40.5% (15/37) and 31.6% (6/19) in two retrospective studies, respectively) in PSC patients. In summary, patients should receive operations at an early stage and multimodality treatments are needed to maximize the benefits of patients with advanced disease.

Solder paste printing is the first part of the surface mount process flow; its postprinting defect inspection is particularly important. In this paper, we focus on studying the printing defects inspection algorithm for solder paste on PCB (Printed Circuit Board) images. The work proposes a number of methods to enhance the defects inspection performance of solder paste printing: a regional multidirectional data fusion image interpolation method, which can achieve fast and high precision image interpolation; a method for detecting solder paste areas with better accuracy, efficiency, and robustness; an improved connected domain labeling method to reduce time complexity; and defects detection and types classification method, which extracts features and centroid of every solder paste region and completes the inspection by comparing with a standard image. The experiments show that the defects inspection algorithm can detect the most common types of defects with low time consumption, high inspection accuracy, and classification accuracy.

Published: March 2022

Ion-selective electrodes directly respond to the activity of target ions without destroying the existing form of the original electrolyte, so ion-selective electrodes have been widely used in various fields. Mean activity coefficient of NaNO3 in the ternary system (NaNO3 + CsNO3 + H2O) at 298.15 K was measured by electromotive force (EMF) with the cell: Na+ ion-selective electrode (Na-ISE)|NaNO3 (mA), CsNO3 (mB)|NO3- ion-selective electrode (NO3-ISE) with total ionic strengths from 0.01 to 4.5 mol·kg-1 at different ionic strength fractions (0, 0.1, 0.2, 0.4, 0.6, and 0.8). The results showed that the Na-ISE and NO3-ISE have a good Nernst response, and the mean activity coefficients of NaNO3 are obtained via the Nernst equation. Based on the data of mean activity coefficients of NaNO3, the relationship diagrams of activity coefficients of NaNO3 against ion strengths in the ternary system were demonstrated, and the Pitzer mixing ion-interaction parameters

Authors: Samaké Abdoulaye , Mahamane Amadou , Diallo Ouaténi
Published: March 2022

We present a computational framework for the parallel implementation of a local-scale air quality model described by an advection-diffusion-reaction partial differential equation, the so-called equation of reactive dispersion. The temporal discretization of the model is carried out using the forward Euler scheme. The spatial discretization is achieved using the finite element method. The strategy used for the parallel implementation is based on the distributed-memory approach using the message-passing library MPI. The simulations are focused on two road traffic-related air pollutants, namely particulate matters PM2.5 and PM10. The efficiency and the scalability of the parallel implementation are illustrated by numerical experiments performed using up to 128 processor cores of a cluster computing system.
Relationship between Parents’ Educational Expectations and Children’s Growth Based on NVivo 12.0 Qualitative Software
Authors: Guo Xiaohua
Published: March 2022

The relationship between parents’ educational expectations and children’s growth is a hot topic in family education. In this study, in-depth interviews are conducted with 30 elementary school students and their parents, and the interview data are analyzed by NVivo 12.0 qualitative software. Based on the data from NVivo 12.0, this study initially constructs a model of the relationship between parents' educational expectations and children’s growth. This study consists of six parts, including introduction, literature review, research method and materials, results and discussion, and conclusions. The study finds that the educational expectations of elementary school students’ parents include three main contents: their children’s quality expectations, learning expectations, and life expectations; the differences in perceptions of educational expectations lead to differences in parents’ behaviors, which in turn affects the children’s growth; parents should maintain high expectations for their children when there is a deviation between children’s growth and parents’ expectations, and parents should not make a simple attribution to children and lower expectations; parental educational ways and teaching by words and deeds are the guarantees of parents’ educational expectations and the conditions for promoting children’s growth; national education policy is the fundamental guarantee to promote parents’ educational expectations and children’s growth. The research conclusions have different opinions on the content and cognition of parents’ educational expectations and can provide a scientific basis for parents’ family education guidance.

A checklist of Cyanobacteria (Blue-green algae) has been made by reviewing available literature in order to contribute to the knowledge of biodiversity of algae in the Punjab state of India. The list records 317 taxa of the phylum Cyanobacteria distributed among 74 genera, 32 families, and six orders. The order Oscillatoriales has 115 taxa, followed by Nostocales (84), Synechococcales (60), Chroococcales (49), Spirulinales (8), and Pleurocapsales (1). The family Nostocaceae has the maximum number of genera followed by Microcoleaceae, Chroococcaceae, Oscillatoriaceae and other reported families. The genera with the highest number of species were Phormidium (39 species), Lyngbya (15 species), Oscillatoria (14 species), and Leptolyngbya & Scytonema (13 species each). The checklist revealed a high degree of species richness within phylum Cyanobacteria found in Punjab. This checklist can provide a baseline for future floristic studies with taxonomically updated/accepted name of genera/species of cyanobacteria.

Authors: Mir Zahoor Ahmad , Bakhtiyar Yahya
Published: March 2022

This paper presents the spatial and temporal variation in the diversity of malacofauna in relation to the water chemistry of the Aripal stream of Kashmir Himalaya. A total of 12 species were reported which belong to four families, Lymnaeidae, Physidae, Planorbidae, and Bithyniidae from class Gastropoda, and two families, Cyrenidae and Pisidiidae from class Bivalvia. The family Planorbidae contributed 34% to the total annual molluscan population followed by Lymnaeidae (28%) and Bithyniidae (18%). During the collection, Gyraulus sp., Planorbis sp., and Bithynia tentaculata were prevalent at all sites, with predominance of Bithynia tentaculata. Species richness and abundance were observed maximum at site A3 (down-stream) and minimum at site A1 (up-stream) while in the case of temporal variation, species richness and abundance were maximum in summer and minimum in winter. Shannon-Wiener index, Simpson index, Margalef index, and Pielou evenness index were used to calculate the diversity, dominance, richness, and evenness of molluscan species, respectively. Physico-chemical parameters revealed a non-significant spatial variation (P >0.05) except pH, total hardness, and alkalinity while a significant temporal variation (P <0.05) was observed in the physico-chemical parameters except dissolved oxygen. A significant positive correlation was seen between the molluscan species and total hardness. In the present study, the stone mining, channel morphology of stream, habitat heterogeneity, and physico-chemical parameters were also found to promote the spatial and temporal diversity of malacofauna.

Authors: Zhen Yanhua , Lu Xuefeng , Cui Jinquan
Published: March 2022

Our study elucidated the therapeutic effect and mechanism of CXCR4 functional selective allosteric agonist ATI2341 TFA on treating Asherman syndrome (AS). AS was established by damaging mouse uterus and the bone marrow cells from ubiquitin-GFP mice were transplanted into AS mice. After
2 weeks, PBS, CXCR4 agonist ATI2341 TFA, CXCR4 antagonist or combined drugs were administrated into mice followed by analysis of detect pregnancy rate, litter size and pregnancy cycle. In AS model, ATI2341 TFA administration promoted BMSCs recruitment into uterine, which was inhibited by CXCL12
receptor antagonist ADM3100. In addition, ATI2341 TFA administration mitigated the degree of endometrial fibrosis, which was exacerbated by ADM3100. ATI2341 TFA administration also improved the fertility and the number of litter and shorten the pregnancy cycle of mice, while ADM3100 exhibited
the opposite impacts. In conclusion, CXCR4 receptor agonist alleviates the infertility or adverse pregnancy outcomes possibly through promoting the recruitment of BMSCs in AS mice.

Authors: Shi Lei , Hou Baoke
Published: March 2022

This study explored urokinase’s effect on the production of heat shock protein 27 in chronic glaucoma rats. 45 SD rats were equally assigned into healthy group, glaucoma group, and urokinase group followed by analysis of intraocular pressure by TONO-PENAVVI tonometer, apoptosis
of retinal ganglion cells by TUNEL staining, pathological morphology by H&E staining, levels of SOD, MDA, and NO as well as the expression of HSP27 and p-p38MAPK. After treatment, the intraocular pressure was increased in glaucoma group and decreased in urokinase group (P < 0.05).
In addition, glaucoma group showed significantly increased apoptosis rate (P < 0.05) which was decreased in urokinase group (P < 0.05). In glaucoma group, the nerve fibers were disorderly arranged and ganglion cells were greatly reduced which were improved in urokinase
group. Compared to healthy group, glaucoma group had lower MDA level and higher SOD levels (P < 0.05) which were reversed in urokinase group (P < 0.05). HSP27 and P-P38MAPK levels in glaucoma group were higher than healthy group (P < 0.05) and urokinase group
(P < 0.05). In conclusion, urokinase can reduce the apoptosis of retinal ganglion cells in glaucoma rats and protect the function of the optic nerve by reducing the level of HSP27.
