More specifically, the venom of Apis mellifera syriaca was shown to exhibit various biological effects, including antimicrobial effects. It is suggested that the anti-microbial effect of venom could be accompanied by an immunomodulatory response in the host favoring anti-inflammatory responses. Thus, in this work, we investigated, for the first time, the immunomodulatory effects of <i>A. mellifera syriaca</i> venom in mice. Firstly, it was found that this venom exhibited mild toxicity in BALB/c mice after intraperitoneal injection with an LD50 of 3.8 mg/kg. We then investigated its immunomodulatory effects by evaluating the splenic levels of both pro- and anti-inflammatory cytokines in mice by ELISA. Interestingly, at 1 mg/kg, <i>A. mellifera syriaca</i> venom induced a decrease in IFN-γ, TNF-α, IL-4, and IL-10 at 24h postinjection. At a higher dose (3 mg/kg), an increase in IFN-γ and IL-4 levels was observed, while the levels of TNF-α and IL-10 remained low compared to the control. Altogether, these preliminary data suggest that <i>A. mellifera syriaca</i> venom exhibits anti-inflammatory effects at a sublethal dose (1 mg/kg), while at a higher dose (3 mg/kg), it induces inflammatory effects.</p>","PeriodicalId":13678,"journal":{"name":"Infectious disorders drug targets","volume":" ","pages":"e230623218222"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9739556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a wide range of symptoms associated with these contagious microorganisms, from watery diarrhea to fulminant dysentery manifesting with recurrent bloody stools, fever, and prostration. While the mortality rate from Shigellosis has decreased significantly during the past three decades, it remains a principal cause of death in the world. The use of antibiotics in Shigella treatment remarkably lowers the mortality rates and even the prevalence of the infection. However, strains are becoming increasingly resistant, while antibiotics are becoming increasingly ineffective. Shigella species, which were previously susceptible to common antibiotics such as nalidixic acid, co-trimoxazole, chloramphenicol, and ampicillin, have become resistant to cephalosporins, fluoroquinolones and macrolides like azithromycin. These strains have caused many Shigellosis outbreaks. Men who have had sex with men (MSM) and travelers have contributed to the spreading of multiresistant Shigella strains across continents, which has prompted new antibiotic recommendations. People should be informed about the threat of antimicrobial-resistant bacteria, so a periodic report of antibiotic susceptibility after analysis is essential for antibiotic treatment guidance.

Still, the outline of variations, particularly the most current delta divergent, has posed significant health encounters for people. Therefore, developing strong treatment strategies, such as an anti-COVID-19 medicine plan, may help deal with the pandemic more effectively. During the COVID-19 pandemic, some drug design techniques were effectively used to develop and substantiate relevant critical medications. Extensive research, both experimental and computational, has been dedicated to comprehending and characterizing the devastating COVID-19 disease. The urgency of the situation has led to the publication of over 130,000 COVID-19-related research papers in peer-reviewed journals and preprint servers. A significant focus of these efforts has been the identification of novel drug candidates and the repurposing of existing drugs to combat the virus. Many projects have utilized computational or computer-aided approaches to facilitate their studies. In this overview, we will explore the key computational methods and their applications in the discovery of small-molecule therapeutics for COVID-19, as reported in the research literature. We believe that the true effectiveness of computational tools lies in their ability to provide actionable and experimentally testable hypotheses, which in turn facilitate the discovery of new drugs and combinations thereof.

Also, we examined some factors associated with the time to survival among COVID-19 patients in Osun state, Nigeria. Methods The retrospective data of 2596 records of COVID-19 patients in Osun state were analysed in this study. The outcome variable was the \"COVID-19 treatment outcome (survived=1, dead=0)\". The time date used in the survival analysis was treatment duration (in days). The explanatory variables were demographic characteristics, type of health facility, vaccination status, symptoms, and mode of admission. The descriptive statistics was computed and presented. Kaplan Meier was used to estimate the median time to survival. Bivariate analysis and multivariate analysis were done using the Log-Rank test and Cox regression, respectively. P values were set at P<0.05. Results The mean age was observed to be 40 (SD=17.51) years, ranging from mostly, 2 months to 98 years old. More (56.1%) of the participants were males. Most (99.5%) of them were Nigerians. Only 1.4% were vaccinated. The survival rate from COVID-19 was 98.1% in Osun State. The median time for survival was 14 (IQR= 14- 16) days. COVID-19 reduces as the number of days for being on treatment increases. Unvaccinated (HR=0.93, 95%CI: 0.43-2.03) and those whose vaccination status was unknown (HR=0.52, 95%CI: 0.37-0.74) were less likely to survive COVID-19 diseases. Conclusion The Survival rate was high, the observed median time to survival was 14 days, and the probability of survival reduces as the number of days of being on treatment for COVID-19 increases. Also, gender, vaccination, type of care, and ethnicity were associated with survival time. Similarly, unvaccinated and inpatients were less likely to rapidly survive COVID-19. This study recommends that the COVID-19 vaccine should be encouraged among patients who have the COVID-19 virus. Also, home care may be further explored to assess its effectiveness in caring for COVID-19 patients.
