    No full text
    In this paper, we introduce a new class of special polynomials called the generalized Bell polynomials, constructed by combining two-variable general polynomials with two-variable Bell polynomials. The concept of the monomiality principle was employed to establish the generating function and obtain various results for these polynomials. We explore certain related identities, properties, as well as differential and integral formulas. Further, specific members within the generalized Bell family—such as the Gould-Hopper-Bell polynomials, Laguerre-Bell polynomials, truncated-exponential-Bell polynomials, Hermite-Appell-Bell polynomials, and Fubini-Bell polynomials—were examined, unveiling analogous outcomes for each. Finally, Mathematica was utilized to investigate the zero distributions of the Gould-Hopper-Bell polynomials

    Recently, Appell-type polynomials have been investigated and applied in several ways. In this paper, we consider a new extension of Appell-type Changhee polynomials. We introduce two-variable generalized Appell-type λ-Changhee polynomials (2VGATλCHP). The generating function, series representations, and summation identities related to these polynomials are explored. Further, certain symmetry identities involving two-variable generalized Appell-type λ-Changhee polynomials are established. Finally, Mathematica was used to examine the zero distributions of two-variable truncated-exponential Appell-type Changhee polynomials

    Background and aims: The mouth's microflora may alter as a result of dental implants. The purpose of this study was to examine the composition of aerobic bacteria in patients with dental implants and those who had natural teeth (without implants) as well as the response of those bacteria to antibiotic treatment. Methods: Bacteriological tests were performed on 72 patients (36 dental implants and 36 natural teeth) who visited dental clinics run by Sana'a University's Faculty of Dentistry and private dental clinics. Antibiotic susceptibility tests and culture trials were carried out at the National Center for Public Health Laboratories (NCPHL) in Sana'a, Yemen. Swabs were taken from the mucous membrane of the palate and the dorsum of the tongue from both groups, and cultured on selective and non-selective solid medium, in addition to culturing the swabs on medium enriched with 5% blood, then all cultured plates were incubated to microaerophilic conditions (5% CO2) and oxygenated in 37oC for 48 hours. Then bacterial growth was identified by standard methods. Results: In implant patients, the rate of bacterial isolates from the palate and tongue was slightly higher for potentially harmful bacteria such as E. coli (8.3% in tongue implant patients vs. 2.8% in non-implant patients) and Pseudomonas aeruginosa (5.6% versus 0%). While in viridians Streptococcus including S. mutans, there was a higher colonization rate in implants patients (83.3% in the palate verses, 75% in the palate of individuals without implants). A low level of oxacillin resistance (5.1%) in S. mutans isolates but S. mutans had a substantial level of tetracycline resistance (55.93%), 11.9% for co-trimoxazole, 10.2% for erythromycin, and just 1.7% for clindamycin. Conclusion: The study found that pathogenic bacteria like E. coli and Pseudomonas aeruginosa were isolated from the palate and the back of the tongue swabs at a slightly elevated rate in implant patients; also colonization rates of Streptococcus viridians, including S. mutans, were higher in implant patients compared to those without implants. There was a significant levels of antibiotics resistance in S. aureus, CoNs and S. viridians oral isolates in both groups of tested individuals.                           Peer Review History: Received: 14 June 2023; Revised: 13 July; Accepted: 17 August, Available online: 15 September 2023 Academic Editor: Dr. A.A.

    Morphological, nutritional and molecular analyses were carried out to assess genetic diversity among 35 introduced lentil genotypes (Lens culinaris Medik.). The genotypes exhibited significant differences for their field parameters and some of them showed noticeable superiority. The nutritional and proximate analysis showed that some genotypes were excellent sources of proteins, essential amino acids, minerals, anti-oxidants, total phenolic contents (TPC) and total flavonoid contents (TFC) and hence, highlights lentil nutritional and medicinal potential. Sequence-related amplified polymorphism (SRAP) and amplified fragments length polymorphism (AFLP) markers were used to estimate the genetic variability at the molecular level. The existence of a considerable amount of genetic diversity among the tested lentil genotypes was also proven at the molecular level. A total of 2894 polymorphic SRAP and 1625 AFLP loci were successfully amplified using six SRAP and four AFLP primer pair combinations. Polymorphism information content (PIC) values for SRAP and AFLP markers were higher than 0.8, indicating the power and higher resolution of those marker systems in detecting molecular diversity. UPGMA (unweighted pair group method with arithmetic average) cluster analysis based on molecular data revealed large number of sub clusters among genotypes, indicating high diversity levels. The data presented here showed that FLIP2009-64L and FLIP2009-69L could be used as a significant source of yield, total protein, essential amino acids, and antioxidant properties. The results suggest potential lentil cultivation in the central region of Saudi Arabia for its nutritional and medicinal properties, as well as sustainable soil fertility crop
