Article Synopsis
  • Drug development using medicinal plants is a crucial approach for discovering natural cancer treatments, though the specific mechanisms of action are often unclear.
  • While research has primarily focused on genetic and protein analysis, the study of metabolites (metabolomics) is gaining attention for its potential to identify anticancer compounds and understand how cancer cells respond to treatments.
  • This review highlights the importance of plant metabolomics in cancer research and outlines the necessary components for conducting effective analyses in this field, despite ongoing challenges.

Several comorbidities and illnesses have emerged after the COVID-19 pandemic and the introduction of vaccination based on a slightly modified SARS-CoV-2 spike protein. One of these diseases is epilepsy, where the dysfunctional RAS plays a crucial role in the propagation of the disorder. SARS-CoV-2 infects host cells by utilizing the angiotensin-converting enzyme Type 2 (ACE2) receptor, which allows the virus to infect various cell types, including those in the lungs, nasopharynx, kidneys, lymph nodes, small intestine, stomach, spleen, and brain, leading to widespread organ damage.

Glioblastoma multiforme (GBM) is a highly aggressive and fatal primary brain tumor. The resistance of GBM to conventional treatments is attributed to factors such as the blood-brain barrier, tumor heterogeneity, and treatment-resistant stem cells. Current therapeutic efforts show limited survival benefits, emphasizing the urgent need for novel treatments.

Antimicrobial resistance (AMR) poses a serious global health concern, resulting in a significant number of deaths annually due to infections that are resistant to treatment. Amidst this crisis, antimicrobial peptides (AMPs) have emerged as promising alternatives to conventional antibiotics (ATBs). These cationic peptides, naturally produced by all kingdoms of life, play a crucial role in the innate immune system of multicellular organisms and in bacterial interspecies competition by exhibiting broad-spectrum activity against bacteria, fungi, viruses, and parasites.

The study of neuroarchitecture is concerned with the significant effects of architecture on human behavior, emotions and thought processes. This review explores the intricate relationship between the brain and perceived environments, focusing on the roles of the anterior cingulate cortex (ACC) and parahippocampal place area (PPA) in processing architectural stimuli. It highlights the importance of mirror neurons in generating empathetic responses to our surroundings and discusses how architectural elements like lighting, color, and space layout significantly impact emotional and cognitive experiences.

In 2020, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) challenged the world with a global outbreak that led to millions of deaths worldwide. Coronavirus disease 2019 (COVID-19) is the symptomatic manifestation of this virus, which can range from flu-like symptoms to utter clinical complications and even death. Since there was no clear medicine that could tackle this infection or lower its complications with minimal adverse effects on the patients' health, the world health organization (WHO) developed awareness programs to lower the infection rate and limit the fast spread of this virus.

The French Society of Toxinology (SFET), which celebrated its 30th anniversary this year, organized its 29th annual Meeting (RT29), shared by 87 participants, on 30 November-1 December 2023. The RT29 main theme, "Toxins: From the Wild to the Lab", focused on research in the field of animal venoms and animal, bacterial, fungal, or plant toxins, from their discovery in nature to their study in the laboratory. The exploration of the functions of toxins, their structures, their molecular or cellular ligands, their mode of action, and their potential therapeutic applications were emphasized during oral communications and posters through three sessions, of which each was dedicated to a secondary theme.

Scorpion venoms have long captivated scientific researchers, primarily due to the potency and specificity of the mechanism of action of their derived components. Among other molecules, these venoms contain highly active compounds, including antimicrobial peptides (AMPs) and ion channel-specific components that selectively target biological receptors with remarkable affinity. Some of these receptors have emerged as prime therapeutic targets for addressing various human pathologies, including cancer and infectious diseases, and have served as models for designing novel drugs.

Enteroviruses (EVs) include many human pathogens of increasing public health concern. These EVs are often associated with mild clinical manifestations, but they can lead to serious complications such as encephalitis, meningitis, pneumonia, myocarditis or poliomyelitis. Despite significant advances, there is no approved antiviral therapy for the treatment of enterovirus infections.

Bee venoms are well-known for their important biological activities. 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.

ATP, the power of all cellular functions, is constantly used and produced by cells. The enzyme called ATP synthase is the energy factory in all cells, which produces ATP by adding inorganic phosphate (Pi) to ADP. It is found in the inner, thylakoid and plasma membranes of mitochondria, chloroplasts and bacteria, respectively.

Since the discovery of olfactory receptor (OR) genes, their expression in non-olfactory tissues have been reported in rodents and humans. For example, mouse OR23 (mOR23) is expressed in sperm and muscle cells and has been proposed to play a role in chemotaxis and muscle migration, respectively. In addition, mouse mesencephalic dopaminergic neurons express various ORs, which respond to corresponding ligands.
