The objective of this study was to investigate the effect of honey on high glucose-induced PPH in alloxan-induced diabetic rats. Diabetes mellitus was induced in overnight-fasted rats by administering alloxan [150 mg/kg body weight (BW)]. The diabetic rats were administered either drinking water (1 ml/kg BW) or honey (1, 2 or 3 g/kg BW) via oral gavage. Each group consisted of six rats. Prior to the administration of either the drinking water or the honey, the baseline fasting blood glucose (BG) was measured and recorded as BG₀. Subsequently, BG levels (BG₆₀, BG₁₂₀ and BG₁₈₀) were assessed at 60, 120 and 180 minutes, respectively. The estimation of the BG parameters concentration was performed, including the area under the curve (AUC), the peak BG (PBG), the percentage change in BG. The AUC and PBG did not differ between the diabetic groups (regardless of administered agents) and the diabetic control group. Compared with baseline fasting blood glucose (BG₀), the BG₆₀ significantly (<i>p</i> < 0.05) increased in diabetic rats that received drinking water or honey (2 or 3 g/kg BW) but not in diabetic rats that received 1 g/kg BW of honey.

There is an alarming potential for this infection to progress into gastric cancer if left unaddressed. However, the efficacy of conventional treatments is undermined by the growing challenge of antibiotic resistance and the necessity for complex multidrug and high-dose therapeutic regimens. Furthermore, the presence of factors such as biofilm formation, efflux pumps, and gene mutations significantly elevates the risk of treatment failure. In view of these significant challenges, contemporary drug delivery systems represent a vital adjunct in the battle against <i>H. pylori</i>. These advanced and sophisticated systems offer significant advantages, including enhanced drug protection, controlled release, and targeted delivery to specific tissues. Nanoparticles, in particular, show promise in combating <i>H. pylori</i> infection through a variety of mechanisms, including direct drug delivery into the bacteria and the destruction of bacterial walls, as well as generation of free radicals. This review provides an overview of the current therapeutic landscape, including both existing and evolving treatment options. It delves into the transformative potential of novel drug delivery systems, including micro- and nanoparticles, to play a transformative role in the complex field of <i>H. pylori</i> infection treatment. By examining the complex relationship between infection dynamics and cutting-edge delivery technologies, this review seeks to identify avenues for more effective and targeted interventions against this persistent threat. As our understanding of <i>H. pylori</i> infection advances, new treatments and enhanced drug delivery methods offer the prospect of a more effective and personalized approach to combating this persistent health problem.

It is a disease caused by pathogenic Leptospira. The early detection of pathogenic Leptospira is an effective method for preventing a multitude of potential complications. The protected outer membrane protein (OMP) of pathogenic Leptospira, LipL41-OmpL1, was inserted into E. coli bacteria using different software for the amino acid sequence of OmpL1 and LipL41. This was done to design a recombinant fusion protein, which was then expressed to investigate immunogenicity. The selected genes were propagated and cloned as a fusion in a PET32a+ plasmid vector and expressed by Escherichia coli strain S (DE3) via a heat shock method. The evaluation was conducted using the BALB/c mouse as the laboratory animal model. The recombinant LipL41-OmpL1 protein was confirmed using the urea purification method and western blot, and its immunogenicity was evaluated by measuring the high humoral immune stimulation and antibody secretion in BALB/c mice by the ELISA method. The findings demonstrated that the animals that received both the OmpL1 and LipL41 proteins exhibited 85% immunogenicity, whereas the control group that did not receive the fusion protein demonstrated only 25% immunogenicity (P<0.001). Moreover, no evidence of infection was identified in recipients of the OmpL1-LipL41 fusion protein, indicating that this protein is safe for use. The protective effects of immunization with OmpL1 and LipL41 were synergistic, as no significant levels of protection were observed in animals immunized with OmpL1 or LipL41 alone.
