Strains of &lt;em&gt;S. aureus&lt;/em&gt; exhibit a wide variety of virulence traits, including the ability to generate various toxins and develop treatment resistance. MRSA is characterized by its resistance to a range of beta-lactam antibiotics. This study’s objectives included assessing the frequency of &lt;em&gt;S. aureus&lt;/em&gt; infection in SCA patients, analyzing laboratory markers of the CBC test, examining the antibiotic susceptibility pattern, and investigating the &lt;em&gt;mecA&lt;/em&gt; gene and heteroresistance, which could potentially link to a higher occurrence of &lt;em&gt;S. aureus&lt;/em&gt; infection in SCA patients. The retrospective study was done to gather clinical data on individuals with sickle cell anemia (SCA) who had bloodstream infections. From 2017 to 2021, blood samples and data were gathered by King Saud University Medical City (KSUMC) in Riyadh, Saudi Arabia. The &lt;em&gt;S. aureus&lt;/em&gt; strains were re-cultivation, Vitek system and PCR techniques were employed to ascertain the antibiotic resistance patterns. It was confirmed that 2406 patients with SCD had contracted an infection. A total of 138 (5.73 %) patients with SCD were diagnosed with bacteremia. “Of the 138 strains isolated, the MRSA strain revealed as the most prevailing, including 30 isolates (21.7 %), whereas non-MRSA strains constituted 17 isolates (12.3 %).” Males had a higher rate of infection compared to females. The results indicated that all the &lt;em&gt;S. aureus&lt;/em&gt; isolates exhibited resistance to ampicillin, while the resistance to penicillin was 98 %. Furthermore, the results indicated that over 65 % of the isolates exhibited resistance to amoxicillin, amoxicillin, cefazolin, imipenem, and oxacillin. The &lt;em&gt;mecA&lt;/em&gt; gene was identified in all &lt;em&gt;S. aureus&lt;/em&gt; strains obtained from patients with SCD. The current study recognizes the PCR assay as a more dependable technique for assessing antibiotic resistances, in contrast to the Vitek method. A study found strong links between &lt;em&gt;S. aureus&lt;/em&gt; infections in individuals with SCD and three different factors: hemoglobin (Hb) level, mean corpuscular volume (RDW), and white blood cell (WBC) count (p &lt; 0.004, 0.005, and 0.02, respectively). The study revealed that 34 % of the &lt;em&gt;S. aureus&lt;/em&gt; strains that were examined exhibited heteroresistance to the &lt;em&gt;mecA&lt;/em&gt; gene as well as resistance to oxacillin. The results clearly demonstrated that Ampicillin, Penicillin, amoxicillin, cefazolin, imipenem, and oxacillin are unsuitable choices for the treatment of blood infections in individuals with SCD. “The findings of this study confirmed that all &lt;em&gt;S. aureus&lt;/em&gt; isolates were sensitive to gentamicin, and more than 80 % of the isolates were sensitive to ciprofloxacin, moxifloxacin, levofloxacin, clindamycin, and vancomycin.” Further investigation is nec","PeriodicalId":16205,"journal":{"name":"Journal of King Saud University - Science","volume":"36 11","pages":"Article 103542"},"PeriodicalIF":3.7,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142658750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aims to detect and analyze the different structural elements in the western Neom city. It also attempts to provide valuable data to help decision-makers for better achievement of such vital projects. From field investigation, the study area mainly comprises Neogene sedimentary sequence and exhibits a complex structural architecture represented by extensional- and wrench-style deformations. Different fault orientations (NNW–SSE striking extensional faults, WNW–ESE and ENE–WSW striking oblique-slip faults, and NNE–SSW and NNW–SSE striking strike-slip faults) dissect the western Neom area. Individual NNW-oriented Red Sea Rift-related extensional faults and fault blocks are antithetically tilted to the northeast. The sinistral movement onset along the Dead Sea Transform Fault postdates the Lower Miocene Burqan Formation deposition. Furthermore, the sinistral strike-slip regime of the western Neom area involves extensional structures, including normal faults, contractional structures (folds and reverse faults), and structures representing horizontal shear on near-vertical planes. NNW-oriented negative flower structures and forced folding occur along a synthetic NNW-oriented sinistral strike-slip fault set. Contractional structures are expressed by sets of NE-oriented left-handed en echelon-arranged folds in the Middle Miocene deposits. A proposed strain ellipse reveals these structures are associated with the NNE-oriented sinistral Dead Sea Transform Fault. The complexity of the structural architecture of the western Neom area can be attributed to its geologic setting under the influence of the Red Sea extensional rifting followed by the tectonic activity along the Dead Sea transform faulting. It is recommended that the structural attributes investigated, especially the geographic distribution of brittle structures (faults and fractures), be considered during the construction of Neom City.</div></div>","PeriodicalId":16205,"journal":{"name":"Journal of King Saud University - Science","volume":"36 11","pages":"Article 103532"},"PeriodicalIF":3.7,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142658801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work investigates the electronic structure and reactivity of 2-thiophenecarbonitrile (2TCN) with an emphasis on important factors such as HOMO-LUMO energy gap, MEP, Mulliken atomic charges, natural population analysis, and Mutiwfn (ELF, LOL, ALIE, and RDG) analysis. The MEP and FMO studies were calculated in various solvents like acetonitrile, water, gas, and methanol. The anti-inflammatory and antioxidant investigations revealed substantial activities by 2TCN. Additionally, molecular docking studies are performed to elucidate the binding interaction between the compound and target proteins, providing insights into its potential therapeutic mechanisms. The results demonstrate the binding energies, interaction residues, and the most favorable docking poses. This approach underscores the integration of theoretical and computational methods in advancing molecule design and therapeutic discovery.</div></div>","PeriodicalId":16205,"journal":{"name":"Journal of King Saud University - Science","volume":"36 11","pages":"Article 103526"},"PeriodicalIF":3.7,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142658836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
