Colon carcinogenesis is ranked second globally among human diseases after cardiovascular failures. Bee venom (BV) has been shown to possess in vitro anticancer effects against several types of cancer cells. The two main biopeptides Apis mellifera BV, namely, melittin (MEL) and phospholipase A2 (PLA2), are suspected be the biomolecules responsible for activity. present work aims evaluate cytotoxic effect A. on colon carcinoma cells (HCT116), assess synergistic MEL PLA2 these After analyzing,...

Hyperalgesia is a condition marked by an abnormal increase in pain sensitivity, often occurring response to tissue injury, inflammation, or prolonged exposure certain medications. Inflammatory mediators, such as cytokines IL-1β, IL-6, and TNF-α, play central role this process, amplifying perception. Developing effective treatments that address the underlying mechanisms of hyperalgesia active field research. Apis mellifera syriaca venom demonstrated potential immunomodulatory activity...

Introduction: Combining multiple natural extracts may provide an additive and/or synergistic effect, increasing the anti-cancer potential of formulation while aiding in search for targeted chemical compounds cancer treatment. Method: Here, we confirmed individual vitro anti-proliferation effect Apis mellifera syriaca bee venom (BV) and Jania rubens red algae polysaccharide extract (PE) on HCT-116 HT-29 colon cell lines explored these two extracts, aiming to develop a new mixture with...

Three hundred and eleven honeybee samples from 12 countries in the Middle East North Africa (MENA) (Jordan, Lebanon, Syria, Iraq, Egypt, Libya, Tunisia, Algeria, Morocco, Yemen, Palestine, Sudan) were analyzed for presence of deformed wing virus (DWV). The prevalence DWV throughout MENA region was pervasive, but variable. highest found Lebanon with dropping Jordan, Egypt before increasing slightly moving westwards to Algeria Morocco Phylogenetic analysis a 194 nucleotide section Lp gene did...

Bee venom (BV) is one of the most remarkable natural products that has been a subject studies since ancient times. Recent have shown Apis mellifera syriaca possesses antibacterial as well cytotoxic effects on cancer cell lines. The contains variety bioactive molecules—mainly melittin (MEL) and phospholipase A2 (PLA2), other compounds are not characterized. In this work, we continue biological characterization A. by testing its anticoagulant effect human plasma using prothrombin time (PT)...

Glioblastoma multiforme (GBM) is a highly aggressive and fatal primary brain tumor. The resistance of GBM to conventional treatments attributed factors such as the blood–brain barrier, tumor heterogeneity, treatment-resistant stem cells. Current therapeutic efforts show limited survival benefits, emphasizing urgent need for novel treatments. In this context, natural anti-cancer extracts especially animal venoms have garnered attention their potential benefits. Bee venom in general that...

The Pine Processionary Moth (PPM) Thaumetopoea wilkinsoni has long been attacking Mediterranean forests. In its management strategy, Lebanon focused mainly on pesticides, leaving natural predators as an understudied control option. This study aims to understand the distribution of Eurasian Hoopoe Upupa epops, by assessing damage caused PPM. We attempted explain two species, their relation other factors and, with a Citizen Science (CS) approach, we developed maps. found that varying PPM...
