Research ArticleOpen accessIn the abstractComparative Analysis of Surface Microhardness and Antimicrobial Activity of Conventional and Bioactive Composite Materials for Dental RestorationsBruno Fongaro Dalbosco, Rafael da Silva Vanolli, Poliana Maria de Faveri Cardoso et al.This study evaluated the fluoride release capability, antimicrobial activity, and surface microhardness of bioactive composite resins, critical properties for the effectiveness and durability of dental materials in restorative procedures. Conventional and bioactive composite resins with varying viscosities were tested. Specimens of each resin type were prepared and stored in physiological saline solution for 24 hours to simulate oral conditions. Surface … …Current Research in Dentistry, Vol. 16, Issue 1 · 29 Jan 2026 · 2,809 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBacterial Resistance in Primary Bloodstream Infections in the COVID-19 Pandemic: What has Changed at a Reference Hospital in Northeastern Brazil?Jonathan Da Silva Xavier, Jorge Luiz Nobre Rodrigues, Caroline Mary Gurgel Dias Florêncio et al.The increased use of central venous catheters due to the severity of COVID-19 cases and the difficulty in implementing preventive Healthcare-Associated Infection measures contributed to worsening an already challenging scenario of bacterial resistance. Characterizing the impact of these significant health crises on the bacterial resistance profile is necessary to strengthen antimicrobial control protocols in an effort to decrease morbidity. Our … …American Journal of Infectious Diseases, Vol. 20, Issue 2 · 4 Sep 2024 · 5,033 accessesView PDF Cite

Research ArticleOpen accessIn the abstractChlorophyll and Protein Changes Observed Post Co-Cultivation of Explants with Agrobacterium Tumefaciens in Soybean (Glycine max L. Merr.)Phetole MangenaAlthough, Agrobacterium-mediated genetic transformation represents a major milestone in agricultural biotechnology for crop improvement against biotic and abiotic stresses. Further insights on the interactions between this bacterium and explants required for in vitro plant regeneration remain scant. This study investigated the changes in chlorophyll content and protein profiles of cotyledonary node explants co-cultivated with A. tumefaciens in soybean. Soybean seeds … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 7 Dec 2022 · 5,046 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCharacterization of a Multi-Metal Resistant Bacillus cereus Strain TWSL_5 and it’s Bioremediation Potential for Cr, Pb, Zn and FeWeerasingha Mudiyanselage Nilmini Hasintha Kumari, Naduviladath Vishvanath Chandrasekharan, Champika Dilrukshi WijayarathnaAn effluent sample collected from a textile dyeing factory was screened to isolate metal resistant endogenous bacteria using standard microbiology techniques. A bacterium with the highest metal resistance was characterized by 16S rRNA gene sequencing and the bacterial genome was screened for any possible metal resistant genes using the Polymerase Chain Reaction (PCR). The bioremoval ability of the isolate was … …American Journal of Environmental Sciences, Vol. 17, Issue 3 · 15 Jul 2021 · 6,443 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStructural and Substrate Interaction Properties of Alkaline Phosphatase from Paenibacillus sp. PSB04: In-Silico AnalysisHerman Umbau Lindang, Cahyo BudimanA Phosphate-Solubilising Bacterium (PSB) of Paenibacillus sp. PSB04 was previously isolated from the Sabah tropical rainforest in Malaysia. Interestingly, the genome sequence of the PSB04 strain harbored an Alkaline Phosphatase (AP) (EC 3.1.3.1) gene and was hypothesized to have unique structural characteristics. Therefore, this study aims to determine the AP three-Dimensional (3D) model and catalytic mechanism from Paenibacillus sp. PSB04 … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 16 Jul 2022 · 5,910 accessesView PDF Cite

EditorialOpen accessIn the abstractAssociation between Infective Endocarditis and Premalignant Colorectal LesionsCarles FalcesThe association between Infective Endocarditis (IE) and Colorectal Cancer (CRC) has been known for more than 50 years. The microorganisms in which this association has been described are Streptococcus gallolyticus (formerly Streptococcus bovis) (Corredoira-Sánchez et al., 2012; Boleij et al., 2011), in different subspecies and, more recently, Enterococcus faecalis (Pericàs et al., 2016; 2017; Escolà-Vergé et al., 2020; Pericàs et … …American Journal of Infectious Diseases, Vol. 17, Issue 3 · 10 Jun 2021 · 11,559 accessesView PDF Cite

Case ReportOpen accessIn the abstractA Case of Leptospira Ards- “Obsession with COVID-19 Leading to Delayed Diagnosis of Common DiseasePrakash Tendulkar, Divanshee Sharma, Mukesh Bairwa, Ravi KantLeptospirosis is a bacterial infection caused by spirochaete. It’s a gram-negative bacterium. It spreads Through animal urine or soil or water contaminated with Animal urine (Rat), when coming into contact with mouth, nose, eyes or breach in the skin. It is more common in farmers and people involved in water sports.

Review ArticleOpen accessIn the abstractAntimicrobial Resistance Pattern of Pseudomonas aeruginosa from Different Clinical Specimens: Survey ArticleHosniyeh E. Ladadweh, Hiba H. Falana, Jannat M. Ma’ali et al.Pseudomonas aeruginosa (P.A.) is a gram-negative, aerobic rod bacterium that mainly grows in soil and watery environments, infrequently being a part of microflora in healthy individuals. Since P.A. favors the growth in moistened areas, it can colonize in any simple aqueous solution, which in turn raises the risk of contamination and infection in hospital settings. The emergence of drug resistant … …American Journal of Pharmacology and Toxicology, Vol. 16, Issue 1 · 11 Jan 2021 · 8,396 accessesView PDF Cite
