Abstract
BACKGROUND The increase in nosocomial multidrug resistance and biofilm-forming bacterial infections led to the search for new alternative antimicrobial strategies other than traditional antibiotics. Silver nanoparticles [AgNP] could be a viable treatment due to their wide range of functions, rapid lethality, and minimal resistance potential. The primary aim of this study is to prepare silver nanoparticles and explore their antibacterial activity against biofilms. METHODS AgNPs with specific physicochemical properties such as size, shape, and surface chemistry were prepared using a chemical reduction technique, and then characterized by DLS, SEM, and FTIR. The activity of AgNPs was tested alone and in combination with some antibiotics against MDR Gram-negative and Gram-positive planktonic bacterial cells and their biofilms. Finally, mammalian cell cytotoxicity and hemolytic activity were tested using VERO and human erythrocytes. RESULTS The findings of this study illustrate the success of the chemical reduction method in preparing AgNPs. Results showed that AgNPs have MIC values against planktonic organisms ranging from 0.0625 to 0.125 mg/mL, with the greatest potency against gram-negative bacteria. It also effectively destroyed biofilm-forming cells, with minimal biofilm eradication concentrations [MBEC] ranging from 0.125 to 0.25 mg/ml. AgNPs also had lower toxicity profiles for the MTT test when compared to hemolysis to erythrocytes. Synergistic effect was found between AgNPs and certain antibiotics, where the MIC was dramatically reduced, down to less than 0.00195 mg/ml in some cases. CONCLUSION The present findings encourage the development of alternative therapies with high efficacy and low toxicity.

Abstract
Antimicrobial agents are one of the most widely used drugs in medicine. In the last fifty years, the misuse of these agents caused the emergence of resistant strains of bacteria that led to an increase in life-threatening infections. The need to develop new agents has become a priority, and antimicrobial peptides attained high consideration. The antimicrobial activities of a novel In-house designed hybrid cationic peptide (BKR1) were studied against different strains of Gram-negative bacteria. This was done using the broth dilution method as outlined by the Clinical and Laboratory Institute (CLSI). Checkerboard assy was employed to investigate the synergistic activity of BKR1 peptide with four antibiotics (Levofloxacin, chloramphenicol, rifampicin, and ampicillin). Finally, the cytotoxicity of BKR1 was evaluated against human blood cells and mammalian kidney cells (Vero cells). BKR1 displayed bactericidal activity against tested strains of Gram-negative bacteria, with zero hemolytic effects. It also acts as a strong adjuvant with levofloxacin, chloramphenicol, and rifampicin against resistant strains of P. aeruginosa and E. coli. This study represents the design and elucidation of the antimicrobial activities of a novel hybrid antimicrobial peptide named (BKR1). Our results indicate thar BKR1 is a promising candidate to treat resistant infectious diseases individually or as an adjuvant with conventional antibiotics.

Abstract
BACKGROUND Antibiotics have led to significant advancements in medicine. Unfortunately, they were faced with the emergence of pathogen resistance. According to the World Health Organization, antimicrobial resistance has been declared one of humanity's top ten global public health threats. The risk of those bacteria is not only from their being resistant to multi-antibiotics but also from their ability to form biofilms, which can be 1,000 times more resistant than planktonic bacteria. METHOD This study used rational design to hybridize two antimicrobial peptides, aiming to enhance their efficacy and stability with reduced toxicity. RESULTS The MY8 novel peptide was designed from the parent peptides BMAP-27 and CAMP 211-225. Some amino acid modifications were introduced to the hybrid peptide to improve its physicochemical properties guided by several software. Its antimicrobial activity has been studied against gram-negative and gram-positive strains, which showed broad-spectrum activity with MIC values against planktonic bacteria ranging from 0.125 to 25 μM. In contrast, 25-200 μM were needed to eradicate biofilms. Moreover, the MY8 peptide showed synergism with four conventional antibiotics., It also showed reduced toxicity against mammalian cells and a slight hemolysis tendency towards erythrocytes. CONCLUSION The design of the MY8 peptide was successful, resulting in a novel, potent, broad-spectrum antimicrobial peptide with reduced toxicity and possible synergism with conventional antibiotics.

Abstract
Background Helicobacter pylori (H. pylori) is considered the main cause of gastritis, peptic ulcer and gastric carcinoma in the human populations. H. pylori infection influences the secretion level of several proinflammatory cytokines including IL-1β, which encoded by the IL-1B gene. Objective The current study aimed to investigate whether IL-1B gene polymorphisms are associated with H. pylori infection among the Jordanian population and responses to triple therapy. Subjects and Methods The gastroscopic examination was performed on 412 subjects for H. pylori infection diagnosis, 257 subjects were found to be infected by H. Pylori (positive cases), whereas 155 subjects were uninfected (negative controls). The IL-1B gene T-31C and C3954T polymorphisms were genotyped by PCR-RFLP. Results It was found that the T-31C polymorphism has a significant association with H. pylori infection (P<0.05), and the TT genotype frequency was significantly higher in infected subjects (50.2%) compared to controls (38.7%). On the other hand, no significant association was detected between C3954T SNPs and H. pylori infection among the Jordanian population. In addition, none of the examined polymorphisms were found to influence the responses to triple therapy. Conclusion The IL-1B gene T-31C SNP might be associated with an enhanced risk of H. pylori infection among the Jordanian population.

Abstract
Objective: Cigarette tobacco smoking has been shown to cause cancer through different mechanisms that include epigenetic modulation of tumor-suppressor genes. In the present study, the association between global and MLH1 gene promoter methylation and waterpipe tobacco smoking was investigated. Materials and Methods: Blood lymphocytes and oral epithelium were sampled from 150 pure waterpipe smokers and 150 never-smokers from Jordan. Methylation assessment was performed using the methylation-specific PCR technique for MLH1 gene and ELISA for global DNA methylation. Results: Significant increases were shown in global DNA methylation as measured in blood lymphocytes (p < 0.01). In addition, increases in MLH1 gene promoter methylation among waterpipe smokers compared to nonsmokers (p < 0.001) in both oral epithelium and blood lymphocytes was also observed. In addition, strong correlation was found between LWDS-10J dependence score and magnitude of promoter specific methylation of MLH1 (r2 = 0.74-0.78, p < 0.001). Moreover, the percentage of methylated MLH1 promoter was not affected by age or gender (p > 0.05). Discussion and Conclusion: Collectively, the results indicate that waterpipe tobacco use is associated with epigenetic changes that might predispose users to lung and blood cancers. The results highlight the need for actions to discourage waterpipe smoking and can be used in cessation interventions that target this type of smoking.

Abstract
Infection with Helicobacter pylori (H. pylori) is very common and affecting about 50% of the worldwide population. Several genetic variations have been implicated in determining the clinical susceptibility to this infection. In the current study, we examined the association between C1236T (rs1045642) and C3435T (rs1045642) single nucleotide polymorphisms (SNPs) in the ABCB1 gene and the prevalence of H. pylori infection among Jordanians. A total of 412 subjects (257 H. pylori-positive cases and 155 H. pylori-negative controls) were recruited and participated in the study, and the genotyping of the ABCB1 gene was performed using RFLP-PCR techniques. A significant association was detected between C1236T and H. pylori infection (p < 0.01). The frequency of CT genotype was significantly higher in the positive cases (40.1%) compared to the controls (21.3%). In addition, the C3435T SNP was weakly associated with H. pylori infection (p = 0.077). Haplotype analysis of C1236T and C3435T SNPs showed that the TT haplotype was present in 22.7% of the positive cases compared to 30.7% of the negative controls (p < 0.05, odds ratio = 0.663, 95% CI: (0.483-0.911)). Consequently, the TT haplotype seems to decrease the risk of H. pylori infection. In conclusion, the current results suggest an association between ABCB1 SNPs and H. pylori infection in the Jordanian population.
