ABSTRACT

Alkaline phosphatases (APs, EC 3.1.3.1) belong to a superfamily of biological macromolecules that dephosphorylate many phosphometabolites and phosphoproteins and their overexpression is intricated in the spread of cancer to liver and bones, neuronal disorders including Alzheimer's disease (AD), inflammation and others. It was hypothesized that cyclooxygenase-2 (COX-2) selective inhibitors may possess anti-APs potential and may be involved in anticancer proceedings. Three COX-2 inhibitors including nimesulide, piroxicam and lornoxicam were evaluated for the inhibition of APs using in silico and in vitro methods. Molecular docking studies against tissue nonspecific alkaline phosphatase (TNAP) offered the best binding affinities for nimesulide (-11.14 kcal/mol) supported with conventional hydrogen bonding and hydrophobic interactions. MD simulations against TNAP for 200 ns and principal component analysis (PCA) reiterated the stability of ligand-receptor complexes. Molecular expression analysis of TNAP enzyme in the breast cancer cell line MCF-7 exhibited 0.24-fold downregulation with 5 µM nimesulide as compared with 0.26-fold standard 10 µM levamisole. In vitro assays against human placental AP (hPAP) displayed potent inhibitions of these drugs with IC50 values of 0.52 ±â€¯0.02 µM to 3.46 ±â€¯0.13 µM and similar results were obtained for bovine intestinal AP (bIAP). The data when generalized collectively emphasizes that the inhibition of APs by COX-2 inhibitors provides another target to work on the development of anticancer drugs.

ABSTRACT

Montelukast, an approved leukotriene receptor 1 (Cys-LT 1) antagonist with anti-inflammatory properties is used for the treatment of asthma and allergic rhinitis. In the present studies, montelukast was subjected to in vitro inhibitory assays followed by kinetic and in silico investigations. Montelukast demonstrated inhibitory activity against yeast α-glucosidase (IC50 44.31 ± 1.21 µM), jack bean urease (JB urease, IC50 8.72 ± 0.23 µM), human placental alkaline phosphatase (hPAP, IC50 17.53 ± 0.19 µM), bovine intestinal alkaline phosphatase (bIAP, IC50 15.18 ± 0.23 µM) and soybean 15-lipoxygenase (15-LOX, IC50 2.41 ± 0.13 µM). Kinetic studies against α-glucosidase and urease enzymes revealed its competitive mode of inhibition. Molecular expression analysis of montelukast in breast cancer cell line MCF-7 down-regulated AP by a factor of 0.27 (5 µM) compared with the 0.26 value for standard inhibitor levamisole (10 µM). Molecular docking estimated a binding affinity ranging -8.82 to -15.65 kcal/mol for the enzymes. Docking against the DNA dodecamer (ID: 1BNA) observed -9.13 kcal/mol via minor groove binding. MD simulations suggested stable binding between montelukast and the target proteins predicting strong inhibitory potential of the ligand. Montelukast features a chloroquinoline, phenyl ring, a cyclopropane group, a carboxylic group and a sulfur atom all of which collectively enhance its inhibitory potential against the said enzymes. These in vitro and computational investigations demonstrate that it is possible and suggested that the interactions of montelukast with more than one targets presented herein may be linked with the side effects presented by this drug and necessitate additional work. The results altogether suggest montelukast as an important structural scaffold possessing multitargeted features and warrant further investigations in repurposing beyond its traditional pharmacological use.

ABSTRACT

Urban atmospheric pollution is global problem and and have become increasingly critical in big cities around the world. Issue of toxic emissions has gained significant attention in the scientific community as the release of pollutants into the atmosphere rising continuously. Although, the Pakistani government has started the Pakistan Clean Air Program to control ambient air quality however, the desired air quality levels are yet to be reached. Since the process of mapping the dispersion of atmospheric pollutants in urban areas is intricate due to its dependence on multiple factors, such as urban vegetation and weather conditions. Therefore, present research focuses on two essential items: (1) the relationship between urban vegetation and atmospheric variables (temperature, relative humidity (RH), sound intensity (SI), CO, CO2, and particulate matter (PM0.5, PM1.0, and PM2.5) and (2) the effect of seasonal change on concentration and magnitude of atmospheric variables. A geographic Information System (GIS) was utilized to map urban atmospheric variables dispersion in the residential areas of Faisalabad, Pakistan. Pearson correlation and principal component analyses were performed to establish the relationship between urban atmospheric pollutants, urban vegetation, and seasonal variation. The results showed a positive correlation between urban vegetation, metrological factors, and most of the atmospheric pollutants. Furthermore, PM concentration showed a significant correlation with temperature and urban vegetation cover. GIS distribution maps for PM0.5, PM1.0, PM2.5, and CO2 pollutants showed the highest concentration of pollutants in poorly to the moderated vegetated areas. Therefore, it can be concluded that urban vegetation requires a rigorous design, planning, and cost-benefit analysis to maximize its positive environmental effects.

ABSTRACT

This study delineates the design and synthesis of a series of xanthene-based thiosemicarbazones that show low µM inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), crucial enzymes associated with, among others, Alzheimer's Disease (AD) pathology. Despite FDA-approved AChE inhibitors being frontline treatments for AD, there remains a need for agents exhibiting improved efficacy and selectivity. Our synthesized series demonstrate meaningful inhibition against AChE (IC50 ranging from 4.2 to 62 µM). These compounds exhibit comparatively lower potency against BChE (IC50 values between 64 and 315 µM), showcasing a pronounced AChE selectivity compared to physostigmine. The selectivity index for the compounds between the two targets does vary between 0.02 and 0.75 highlighting that even minor structural differences can have drastic effects on protein interactions. Molecular docking insights further substantiated these observations, revealing the importance of the xanthene scaffold for AChE-binding and the aryl R2 moiety for BChE interactions. Notably, some compounds demonstrated dual enzyme targeting, emphasizing their interactions could be exploited for developing monotherapies against cholinesterase-associated neurodegenerative afflictions like AD. Collectively, these findings suggest that xanthene-based thiosemicarbazones are a promising and highly accessible scaffold that deserve further investigative exploration in the cholinesterase inhibitor therapeutic landscape.Communicated by Ramaswamy H.

ABSTRACT

Glabridin, a polyphenolic flavonoid derived from Glycyrrhiza glabra (licorice) roots, has shown anti-inflammatory and antioxidant properties. The current study sought to investigate glabridin's immunomodulatory effect in ovalbumin induced allergic asthma. Healthy male Wistar rats were divided into five groups. Group I served as a control group. Asthma was induced in groups II- IV. Groups III and IV were treated with glabridin (40 mg/kg) and methylprednisolone (15 mg/kg), respectively. Inflammatory cells counts were determined in blood and bronchoalveolar lavage fluid (BALF). Serum IgE levels and levels of catalase, superoxide dismutase and glutathione peroxidase in lung homogenate were measured. The levels of mRNA expression of pro-inflammatory, anti-inflammatory and oxidative stress markers were analysed. Delayed type hypersensitivity (DTH) and acute toxicity of glabridin were also checked. Glabridin significantly decreased inflammatory cells in the blood and BALF. It increased the concentration of antioxidant enzymes catalase, superoxide dismutase and glutathione peroxidase. Glabridin markedly decreased serum IgE levels and DTH when compared to asthmatic rats. It significantly alleviated the expression of TNF-α, IL-4, IL-5, CXCL1, iNOS, and NF-κB. Administering 10 times the therapeutic dose of glabridin did not show any signs of acute toxicity. Findings suggest that glabridin has the potential to ameliorate allergic asthma and its effects are comparable to those of methylprednisolone. The immunomodulatory effect of glabridin might be contributed by the suppression of pro-inflammatory cytokines, oxidative stress markers, IgE antibodies, and elevation of antioxidant enzymes, suggesting future study and clinical trials to propose it as a candidate to treat allergic asthma.

ABSTRACT

Chrysin (5,7-dihydroxyflavone) has many pharmacological properties including anti-inflammatory actions. The objective of this study was to evaluate the anti-arthritic activity of chrysin and to compare its effect with the non-steroidal anti-inflammatory agent, piroxicam, against complete Freund's adjuvant (CFA)-induced arthritis in a pre-clinical model in rats. Rheumatoid arthritis was induced by injecting CFA intra-dermally in the sub-plantar region of the left hind paw of rats. Chrysin (50 and 100 mg/kg) and piroxicam (10 mg/kg) were given to rats with established arthritis. The model of arthritis was characterized using an index of arthritis, with hematological, biological, molecular, and histopathological parameters. Treatment with chrysin significantly reduced the arthritis score, inflammatory cells, erythrocyte sedimentation rate, and rheumatoid factor. Chrysin also reduced the mRNA levels of tumor necrosis factor, nuclear factor kappa-B, and toll-like recepter-2 and increased anti-inflammatory cytokines interleukin-4 and -10, as well as the hemoglobin levels. Using histopathology and microscopy, chrysin reduced the severity of arthritis in joints, infiltration of inflammatory cells, subcutaneous inflammation, cartilage erosion, bone erosion, and pannus formation. Chrysin showed comparable effects to piroxicam, which is used for the treatment of rheumatoid arthritis. The results showed that chrysin possesses anti-inflammatory and immunomodulatory effects that make it a potential drug for the treatment of arthritis.

ABSTRACT

Spaceflight and microgravity has a significant impact on the immune, central nervous, bone, and muscle support and cardiovascular systems. However, limited studies are available on the adverse effects of long-term microgravity on the intestinal microbiota, metabolism, and its relationships. In this study, a ground-based simulated microgravity (SMG) mouse model was established to evaluate the impact of long-term microgravity on gut microbiota and metabolome. After 8 weeks of SMG, alterations of the intestinal microbiota and metabolites were detected using 16S rRNA sequencing and untargeted metabolomics. Compared to the control, no significant differences in α-diversity were observed at weeks 2, 4 and 8. Nevertheless, there were clear differences in community structures at different time points. The phylum Verrucomicrobia significantly declined from 2 to 8 weeks of SMG, yet the relative abundance of Actinobacteria and Deferribacteres expanded remarkably at weeks 8. SMG decreased the genus of Allobaculum and increased Bacteroides significantly throughout the period of 8 weeks. Besides, Genus Akkermansia, Gracilibacter, Prevotella, Odoribacter, Rothia, Sporosarcina, Gracilibacter, Clostridium, and Mucispirillum were identified as biomarkers for SMG group. Desulfovibrio_c21_c20, Akkermansia_muciniphila, and Ruminococcus_gnavus dropped at week 2, which tend to recover at week 4, except for Akkermansia_muciniphila. Bacteroides_uniformis and Faecalibacterium_prausnitzii declined significantly, while Ruminococcus_flavefaciens and Mucispirillum_schaedleri elevated at week 8. Furthermore, intestinal metabolome analysis showed that 129 were upregulated and 146 metabolites were downregulated in SMG. Long-term SMG most affected steroid hormone biosynthesis, tryptophan, cysteine, methionine, arginine, proline metabolism, and histidine metabolism. Correlated analysis suggested that the potential beneficial taxa Allobaculum, Akkermansia, and Faecalibacterium were negatively associated with tryptophan, histidine, arginine, and proline metabolism, but positively with steroid hormone biosynthesis. Yet Bacteroides, Lachnospiraceae_Clostridium, Rothia, Bilophila, and Coprococcus were positively correlated with arginine, proline, tryptophan, and histidine metabolism, while negatively associated with steroid hormone biosynthesis. These results suggest that Long-term SMG altered the community of intestinal microbiota, and then further disturbed intestinal metabolites and metabolic pathways, which have great potential to help understand and provide clues for revealing the mechanisms of long-term SMG involved diseases.

ABSTRACT

Rheumatoid arthritis is a chronic systemic inflammatory disease with genetic manifestations. According to recently published case reports, patients taking corticosteroid medication for the management of rheumatoid arthritis develop strongloidiasis and are at high risk of developing associated infections. This study explored the antiarthritic role of ivermectin, a drug used in the treatment of strongyloides and to compare its results with dexamethasone. Thirty-two male Wistar rats were randomly divided into four groups: control, diseased, dexamethasone, and ivermectin groups. Rheumatoid arthritis in all rats except the control group was induced by using complete Freund's adjuvant. After 7 days of rheumatoid arthritis induction, animals were treated with dexamethasone 5 mg/kg and ivermectin 6 mg/kg. Body weight, visual arthritic score, total leukocyte count, differential leukocyte count, proinflammatory genes, and histopathological findings were used to assess the effects of ivermectin on rheumatoid arthritis. Treatment with ivermectin showed a significant reduction in inflammatory cells levels, body weight, and visual arthritic score, indicating an improvement in the degree of inflammation as compared with the diseased group. Treatment with ivermectin and dexamethasone significantly reduced the augmentation in the mRNA expression levels of IL-17, TLR-2, TNF, and NF-κB as a result of arthritic development. Ivermectin treatment also showed a significant reduction in the severity of inflammation and destruction of joints and showed comparable effects to dexamethasone, a corticosteroid used for the treatment of rheumatoid arthritis. Ivermectin has significant antiarthritic properties and can be a novel treatment agent for the management of rheumatoid arthritis patients suffering from strongyloidiasis.

ABSTRACT

A series of 1,3,4-oxadiazole-2-thiol derivatives bearing various alkyl or aryl moieties were designed, synthesized, and characterized using modern spectroscopic methods to yield 17 compounds (6a-6q) that were screened for acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes in the search for 'lead' compounds for Alzheimer's disease treatment (AD). The compounds 6q, 6p, 6k, 6o, and 6l showed inhibitory capability against AChE and BChE, with IC50 values ranging from 11.73±0.49 to 27.36±0.29 µM for AChE and 21.83±0.39 to 39.43±0.44 µM for BChE, inhibiting both enzymes within a limited range. The SAR ascertained that the substitution of the aromatic moiety had a profound effect on the AChE and BChE inhibitory potential as compared to the aliphatic substitutions which were supported by the molecular docking studies. The drug-likeness of the most synthesized compounds was confirmed by in silico ADME investigations. These results were additionally supplemented by the molecular orbital analysis (HOMO-LUMO) and electrostatic potential maps got from DFT calculations. ESP maps expose that on all structures, there are two potential binding sites conquered by the most positive and most negative districts.

ABSTRACT

The objective of this study was to deal with the evaluation of 7-(2-(benzylideneamino)-2-(cyclohexa-1,4-dienyl)acetamido)-3-methyl-8-oxo-5-thia-1-aza-bicyclo[4.2.0]oct-2-ene-2-carboxylic acid based schiff bases as a new class of enzyme inhibitors. In this connection, a series of Schiff bases of cephradine with substituted aromatic aldehydes was synthesized and characterized using FTIR, 1HNMR and 13CNMR. The in-vitro biological activities including free radical scavenging potential using DPPH assay, acetyl cholinesterase and butyryl cholinesterase inhibition potential were evaluated. Two compounds of the series 1g and 1h were found to be active against AChE whereas no derivative was active against BChE while the whole series showed excellent 1, 1-diphenyl-2-picrylhydrazyl scavenging activity. All the synthesized compounds were found to be non-toxic and present passive gastrointestinal absorption. Furthermore, the study suggests that the synthesized cephradine derivatives exhibit inhibitory potential against different biologically relevant enzyme targets.

ABSTRACT

Through experiments to testify a candidate novel miRNA previously discovered by us is a real miRNA and involved in cartilage development. DESIGN: The miR-novel and the newly hairpin miRNA transcribed sequence (pre-miR-novel) was verified as a genuinely existing miRNA by northern blotting. The predicted secondary structure, sequence alignment and targets of pre-miR-novel were performed by "RNAstructure 5.3" program, LASTN2.8.0+/miRbase22 program and RNA hybird program, respective. GO/KEGG pathway analysis also were performed. The miR-novel expression in cartilage tissue during development was detected by RT-qPCR and dot blotting. The chondrocyte differentiation model was established to examine whether miR-novel is involved in cartilage development. The regulation of PRMT3 expression by novel miRNA was determined with the luciferase reporter gene assay and Western blotting after novel miRNA mimic or inhibitor transfection. RESULTS: It's potential role in specifically regulating rodent cartilage development and associated cellular processes. Furthermore, the expression of protein arginine N-methyltransferase 3 (PRMT3), as a predicted target of the novel miRNA, was found consistently downregulated at rat cartilage during developmental stages and RCJ3.1C5.18 (C5.18) cells during the proliferating and hypertrophic phases of the cartilage development, where the miR-novel expression was significantly up-regulated. Both the dual-luciferase reporter gene assay and the up- or down-regulation of miR-novel suggest that the later can specifically bind with the Prmt3 3'-UTR. CONCLUSION: Overall, this study provides the first comprehensive evidence that a genuine cartilage-specific novel miRNA directly targets PRMT3 and may regulate multitudinous cellular processes and signal transduction during cartilage development.

ABSTRACT

OBJECTIVE: Both selenium (Se) deficiency and mycotoxin T2 lead to epiphyseal plate lesions, similar to Kashin-Beck disease (KBD). However, regulation of selenoproteins synthesis mediated by SECISBP2, in response to these 2 environmental factors, remained unclear. The present study proposed to explore the mechanism behind the cartilage degradation resulting from Se deficiency and mycotoxin T2 exposure. DESIGN: Deep chondrocyte necrosis and epiphyseal plate lesions were replicated in Dark Agouti (DA) rats by feeding them T2 toxin/Se deficiency artificial synthetic diet for 2 months. RESULTS: Se deficiency led to decreased expression of COL2α1, while T2 treatment reduced the heparan sulfate 6-O-sulfotransferase 2 (HS6ST2) expression, both of which affected the cartilage extracellular matrix metabolism in the rat models. The expression of Col2α1, Acan, Hs6st2, Secisbp2, Gpx1, and Gpx4 were all significantly decreased in cartilage tissues from DA rats, fed a Se-deficient diet or exposed to T2 toxin, contrary to Adamts4, whose expression was increased in both conditions. In addition, T2 treatment led to the decreased expression of SBP2, GPX1, GPX4, and total GPXs activity in C28/I2 cells. CONCLUSION: DA rats exposed to T2 toxin and/or Se-deficient conditions serve as the perfect model of KBD. The 2 environmental risk factors of KBD, which serve as a "double whammy," can intensify the extracellular matrix metabolic imbalance and the antioxidant activity of chondrocytes, leading to articular cartilage degradation and epiphyseal plate abnormalities similar to those observed in KBD.

ABSTRACT

Since the discovery of Deoxyribonucleic acid (DNA) capability in forensic investigation, it has been an important part of the criminal justice system. In most criminal cases DNA profile originating from evidence sample collected from the crime scene is compared with the DNA profile from the reference sample. However, when a reference sample is not available for comparison, familial DNA analysis can provide important investigation leads in a criminal investigation process by identifying an individual. Moreover, this analysis is also proving effective in the identification of ethnicity and ancestry of an individual. A number of different methodologies and software are being used for familial DNA analysis. This review describes the importance of familial DNA analysis, methodologies used for familial DNA searching and identification, and its advantages in forensic. Moreover, ethical, legal and social issues associated with familial DNA analysis have also been discussed along with future directions for the proper implementation of this technology.

ABSTRACT

Electronic word of mouth (eWOM) has become significantly important in online communities, which are influential sources of instant information on the internet. This study examines the eWOM input attributes linked to consumers' information adoption behavior in the context of information-related interaction. This study uses a structural equation modeling approach by choosing participants from Fujian and Guangdong provinces of China. The results reveal that eWOM input attributes studied positively influence information-related interactions. An individual's perception of value enhances the performance of products or services, which is an essential predictor of information adoption. Furthermore, information usefulness and related interactions are key eWOM message characteristics affecting information adoption on the internet. This study contributes to the eWOM input attributes and message characteristics literature by exploring information-related interaction as a new mediator to consumers' online information adoption. The authors provide suggestions for marketers and firms to dynamically develop strategies in response to consumers' concerns while making a purchase online.

ABSTRACT

Good in physical health is a positive outcome in later life associated with well-being. The purpose of this study was to address the factors involved in friends, family and someone's special support that affect physical well-being and psychological well-being, mediated by the spirituality, self-esteem and ego integrity among older adults. Respondents (410) were selected through questionnaire sampling technique from the age of 61 years and above from the four different divisions of Punjab province of Pakistan. It revealed that the hypotheses family support and someone's special support have a positive impact on spirituality, while friends support has a negative impact on spirituality. Spirituality has a slightly positive impact on self-esteem and ego integrity. Self-esteem and ego integrity have a positive influence on physical and physiological well-being, whereas ego integrity has a negative effect and physical well-being. Health and psychological well-being are closely related to each other, which can be distinguished by life satisfaction, happiness and sadness feelings, the meaning of life and sense of purpose. For the enhancement of social support mechanisms, social workers should consider community setting of older people in the Pakistani context.

ABSTRACT

BACKGROUND: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke in humans and the mainstay of treatment is anticoagulation unless contraindicated. Non-vitamin K oral anticoagulants have not been duly evaluated in randomized controlled trials in CVT. OBJECTIVE: To compare the efficacy and safety of oral rivaroxaban with vitamin K anticoagulant (warfarin) in preventing recurrent venous thromboembolism (VTE) in patients with CVT. METHODS: Adult patients with CVT, who were stable after 5-12 days of treatment with parenteral heparin 1 mg/kg, were screened for eligibility. The patients were randomly divided into two groups to receive oral rivaroxaban 20-30 mg daily or warfarin 1, 3 or 5 mg daily (with the dose adjusted to maintain an INR of 2-3), for 3-12 months. Recanalization rates, periprocedural complications, and clinical outcomes were assessed by Magnetic Resonance Venography (MRV) and National Institutes of Health Stroke Scale (NIHSS) at 3rd, 6th and 12th month follow-ups. RESULTS: In total, 45 patients with CVT were randomized to the two treatment groups (21 to rivaroxaban and 24 to warfarin). Overall recanalization was achieved by 18 (86%) and 20 (83%) cases from rivaroxaban and warfarin group, respectively at 6th month follow-up; and by all 45 (100%) cases from the both groups at 12th month follow-up. Excellent outcome (NIHSS score 0) was obtained by 20 (95%) cases from rivaroxaban group at 3rd to 12th month follow-ups; and by 23 (96%) cases at 6th to 12th month follow-ups. There were no major bleeding events during the trial. None of the patients developed recurrence of thrombosis. Statistically, no significant difference between the two treatment groups in terms of recanalization and clinical outcomes could be observed. CONCLUSION: Rivaroxaban is a safe option in CVT however; larger randomized controlled studies will impact the results validity.

ABSTRACT

Hypertension has become a major risk factor for many diseases, including cardiovascular, cerebrovascular and kidney disorders. It has been reported that the composition of human gut microbiota is changed during the progression of cardiovascular and kidney diseases. The current study aimed to qualitatively and quantitatively compare the composition of gut microbiota between patients with hypertension and healthy controls. Fecal samples were collected from 50 patients diagnosed with grade 3 hypertension and 30 healthy controls. Touchdown PCR­denaturing gradient gel electrophoresis with primers specifically targeting the V3 region of 16S ribosomal RNA, and quantitative PCR, were performed to characterize all the samples. High­throughput sequencing of the V3­V4 regions was performed on 30 randomly selected samples. By comparing diversity and richness indices, the gut microbiome of the hypertensive individuals was found to be more diverse than that of the healthy controls. Among the main bacterial phlya that reside in the gut, Bacteroidetes, Firmicutes and Proteobacteria were dominant in all the samples; however the Firmicutes to Bacteroidetes ratio was variable, with a significant increase in the patients with hypertension compared with the healthy control group. In addition, at the genus level, there was an increased abundance of Prevotella_9, Megasphaera, Parasutterella and Escherichia­Shigella in patients with hypertension, while Bacteroides and Faecalibacterium were decreased. These results suggested that the human gut microbiota is altered in hypertension, and understanding the mechanism of these changes in microbial composition may open up new insights, and help to treat hypertension and other related diseases.

ABSTRACT

In this paper, an approximate analytical solution of the bistable Allen-Cahn equation is given. The Allen-Cahn equation is a mathematical model to study the phase separation process in binary alloys and emerged as a convection-diffusion equation in fluid dynamics or reaction-diffusion equation in material sciences. A phase transition occurs at the interface when one material changes its composition or structure. The homotopy perturbation method and homotopy analysis method are used for finding the approximate solution. These methods don't need the use of any transformation, discretization, unrealistic restriction and assumption. The error estimates are computed by comparing with a numerical method, and a good agreement is observed.

ABSTRACT

E-commerce offers an opportunity on web renounced in internet marketing, and the consumers' communication behavior has changed, which has taken the place of word of mouth (WOM). This study investigated consumers' motivational involvement in electronic word of mouth for online information adoption mediated by writers, motivations. Using a sample of 390 active Chinese internet users, it revealed that social tie and perceived risk are essential factors that influence consumers' behavior, occur unpleasant consequences, and the possibility of uncertainties during the decision making process. Online retailers should emphasize perceived risk mitigation enable to provide a quick response on the websites. Practitioners need to understand consumer behavior in the online shopping system for the expansion of the online marketplace to product varieties, online advertising, retail strategies, and market segmentation. Organizations should train their service provides to timely response, concentrate on monitoring the aspects of consumers' reviews, on creating choices among groups and individuals, which can improve the organization's business performance.
