The sample of this study was female mice Balb/c strain, divided into four groups:, the control group (con), the intermittent calorie restriction group (restrict), the MIIT group (interv), and the combine group of intermittent calorie restriction and moderate-intensity interval training (restrict+interv). A high glycemic index diet was a high calorie and was provided by standard feed and oral gavage of 0.013 g/gBW glucosesolution. Intermittent calorie restriction was 50% reduction of the standard feed 3x/week. The MIIT was five-minute intervals of swimming and 30 seconds of passive rest consecutively for 30 minutes and 3x/week. Meanwhile, the treatment duration was four weeks. The oral glucose tolerance test consisting of fasting blood glucose (FBG) and a two-hour post -prandial (2HPP) blood glucose was measured before and after the treatment. CRP was examined only after the treatment. The restrict + interv group had a significant reduction in CRP levels compared to the restricted group (p = 0.005) and the interv group (p = 0.044). The FBG levels the restrict + interv group and restricted group had a significant decrease (p = 0.026). Moreover, 2HPP of the restrict + interv group and restricted group had a significant decline (p = 0.000). This study concludes that the combination of intermittent calorie restriction and moderate -intensity interval training can attenuate elevated serum CRP and blood glucose levels.","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89394365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation of AgNPs was spectrophotometrically detected by the appearance of maximum peak at 430 nm. Transmission electron microscopic results confirmed the formation of AgNPs with different shapes with average particle size (88.94 nm). Phytochemical and gas chromatography/ mass results indicated the presence of important compounds especially phenols and flavonoids in the artichoke waste extract. AgNPs biosynthesized using artichoke waste extract were tested to determine their potential antioxidant, antibacterial and anticancer activities. The results showed that AgNPs have high antioxidant capacity (179.93 mgGAE/ml) and potent free radical scavenging activity (45.94 %). The results also showed that AgNPs have significantly high antibacterial activity against Bacillus cereus, Staphylococcus aureus, Salmonella and Escherichia coli with inhibition zone dimeter 17, 21, 17 and 17 mm, respectively. AgNPs showed anticancer activity against breast cancer cell line with a decline in cells viability with increase of AgNPs concentration and IC50 (144.29μmole/ml). Based on these results and the benefits of phytochemicals detected in artichoke waste extract, this waste could be effectively used for silver nanoparticles preparation.","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86498122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The congestion control technique monitors the process of adjusting the data and intends to manage the network traffic level to the threshold value. The information gathered from an intensive study is required to strengthen the knowledge base for devising a QoS based congestion evasion clustering framework of wireless sensor networks. In this scheme, the cluster heads are optimally determined and dispersed over the network. The data aggregation approach has been applied in a clustered network and set out a crucial paradigm for WSN routing. The proposal employs to mitigate congestion while messages are being forwarded via an alternate route to distribute the traffic and increase the throughput. This technique aims to balance the energy ingestion among the sensor nodes, reduce energy consumption, improve network lifetime, and achieve the quality of services. The result analysis revealed that the proposed scheme recommends 22.5% better throughput, 21% lesser end-to-end delay, 25.5% better delivery ratio, and efficiently relieves congestion while preserving the network's performance for attaining QoS in wireless sensor networks.","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78862451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, mass attenuation coefficient, stopping power, and penetrating distance calculations were performed for cell membranes having an approximately 60-100Å thickness. These calculations have been done for lipid bilayer structure of cell membrane via MC techniques employing two of the most known computer-aided calculation and simulation software which are MC methods such as SRIM-2013 (The Stopping and Range of Ions in Matter) and MCNPv6 (Monte Carlo N-Particle) with XCOM software. Stopping power and penetrating distance calculations were obtained using SRIM-2013. Also, both XCOM software and MCNPv6 simulation code were used to obtain photon interaction parameters within the energy range of 0.01 – 10000keV. Obtained all results from different codes have been visualized by graphing for evaluation.","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90776024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the first time, we have investigated the potential role of Terminalia arjuna as IL-4 and IL-13 modulators for preventing T1DM, i.e., autoimmune diabetes. It has been well documented that the stimulation of IL-4 and IL-13 can regulate the level of type 2 cytokines which can be maintained with the level of type 1 cytokines. In the present study, gallic acid, arjunolic acid, luteolin, ellagic acid, and arjunone were investigated for their potential modulating activity of IL-4 and IL-13. The active amino acid residues identified for IL-4 are VAL51, HIS58, ASP87, THR30, GLN54, THR63, ARG64, LYS84, and GLU60. The active amino acid residues identified for IL-13 are H: GLU46, H: TRP47, H: GLN61, L: PHE98, L: VAL97, L: GLU162, L: THR163, H: ARG105, L: GLN38, L: ASP85, H: GLY42, L: GLY41, H: PRO41, H: TRP47, and L: PHE98. The phytoconstituents demonstrated better modulating activity towards IL-13 than IL-4. Luteolin displayed better potential for both IL-4 and IL-13, and therefore we concluded that it could be used to modulate the activity of IL-4 and IL-13 for the prevention of autoimmune diabetes.","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89526977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
