Intranasal Insulin in Ischemia, Brain Injuries and Diabetes
A decrease in the activity of the insulin signaling system of the brain leads to neurodegeneration and impaired regulation of appetite, metabolism, and endocrine functions. This is due to the neuroprotective properties of brain insulin, its leading role in maintaining glucose homeostasis in the brain, as well as in the regulation of the brain signaling network responsible for the functioning of the nervous, endocrine and other systems. One of the approaches to restore the brain insulin system is the use of intranasally administered insulin (INI). INI is being considered as a promising drug to treat Alzheimer's disease and mild cognitive impairment. Clinical application of INI is being developed for the treatment of other neurodegenerative diseases and improve cognitive abilities in stress, overwork, and depression. It has been shown that INI can be used for the treatment of cerebral ischemia, traumatic brain injuries, postoperative delirium, as well as diabetes mellitus and its complications, including dysfunctions in the gonadal and thyroid axes.

HPV Vaccination for Cervical Cancer Prevention in Switzerland
Human papillomavirus (HPV) is responsible for almost all cases of cervical cancer worldwide. It is also responsible for a variety of other cancers including penile; vaginal; vulvar; anal; and oropharyngeal cancers at the base of the tongue and tonsils. There are a very large number of these HPVs, which are classified into groups from high to low risk based on their oncogenic potential. Every year in Switzerland, over 260 women develop cervical cancer, and nearly 90 of them will die from the disease. Cervical cancer affects young women and is the fourth most common cancer in women between the ages of 20 and 49 years. Among the high-risk HPV types, HPV-16 and -18 are the most common and most carcinogenic ones. Together, these two HPV types are responsible for approximately 70% of cervical cancer cases in developed countries. HPV-6 and -11 are directly responsible for 90% of genital warts. There are two effective public health interventions to prevent this cancer: screening and vaccination. The present entry provides an overview of current literature in order to present these preventative approaches and consider their use within a Swiss context. It is hoped that, going forward, this will encourage the implementation and uptake of such interventions.

Classification of Allosteric G-Protein-Coupled Receptors Regulators
Allosteric regulation is critical for the functioning of G-protein-coupled receptors (GPCRs) and their signaling pathways. Endogenous allosteric regulators of GPCRs are simple ions, various biomolecules (lipids, amino acids, polypeptides, hormonal agents, etc.), and the peptide components of GPCR signaling. According to the ability to influence the basal and orthosteric/allosteric agonist-stimulated activity, the ligands of GPCR allosteric sites can be divided into the positive (PAM), negative (NAM), and silent (SAM) allosteric modulators, the allosteric full agonists, inverse agonists and neutral antagonists, as well as the allosteric regulators with the combined activity (ago-PAM, ago-NAM).

Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitors
The kidneys’ sodium-glucose cotransporter 2 inhibitors (SGLT2) receptors are targeted to reduce glucose reabsorption by SGLT2. Patients with type 2 diabetes mellitus (T2DM) benefit the most from reduced blood glucose levels, although this is just one of the numerous physiological consequences.

Hydrodynamic Delivery
The principle of hydrodynamic delivery was initially used to develop a method for delivering plasmids into mouse hepatocytes through tail vein injection and has since been expanded for use in delivering various biologically active materials to cells in different organs of several animal species.

Strategies for Improving Transdermal Administration
A transdermal delivery system is a painless method of drug administration through intact skin. Transdermal patches favor the controlled release of active ingredients through the skin into systemic circulation.Substances with analgesic effects can be administered on the skin in the form of topical patches made to produce local effects or transdermal patches that ensure the controlled and prolonged release of the active substance.

Plant-Derived Proteasome Inhibitors in Developing Cancer Therapeutics
Homeostasis between protein synthesis and degradation is a critical biological function involving a lot of precise and intricate regulatory systems. The ubiquitin-proteasome pathway (UPP) is a large, multi-protease complex that degrades most intracellular proteins and accounts for about 80% of cellular protein degradation. The proteasome, a massive multi-catalytic proteinase complex that plays a substantial role in protein processing, has been shown to have a wide range of catalytic activity and is at the center of this eukaryotic protein breakdown mechanism. As cancer cells overexpress proteins that induce cell proliferation, while blocking cell death pathways, UPP inhibition has been used as an anticancer therapy to change the balance between protein production and degradation towards cell death. Natural products have unique chemical diversity, which results in diversity in their biological activities and drug-like properties. Physical chemistry has been able to recognize the high structural diversity of natural products. Their efficacy is related to the complexity of their well-organized three-dimensional chemical and steric properties, which offer many advantages in terms of efficiency and the selectivity of molecular targets.

Gut Microbiota in Anxiety and Depression
The gut microbiota is critical for maintaining human health and the immunological system. Several neuroscientific studies have shown the significance of microbiota in developing brain systems. The gut microbiota and the brain are interconnected in a bidirectional relationship, as research on the microbiome–gut–brain axis shows. Significant evidence links anxiety and depression disorders to the community of microbes that live in the gastrointestinal system. Modified diet, fish and omega-3 fatty acid intake, macro- and micro-nutrient intake, prebiotics, probiotics, synbiotics, postbiotics, fecal microbiota transplantation, and 5-HTP regulation may all be utilized to alter the gut microbiota as a treatment approach.

Development of Nitroheterocyclic Drugs against Trypanosomes
Human African Trypanosomiasis (HAT), commonly called sleeping sickness, is a zoonotic disease caused by different subspecies of the bloodstream parasite T. brucei and transmitted by the Glossina tsetse fly. Nitroaromatic rings are privileged pharmacophores of many antimicrobials in clinical use, including antifungal and antiparasitic drugs.

Papaverine and Its Mechanism of Action
Papaverine has been proven to be a high-value opioid alkaloid in the field of therapeutics either in solitude or in combination with other metabolites/molecules. Pharmacological research has revealed that papaverine demonstrates a variety of biological activities, including activity against erectile dysfunction, postoperative vasospasms, and pulmonary vasoconstriction, as well as antiviral, cardioprotective, anti-inflammatory, anticancer, neuroprotective, and gestational actions.
