Glucagon and Its Receptors in the Mammalian Heart
Glucagon exerts effects on the mammalian heart. These effects include alterations in the force of contraction, beating rate, and changes in the cardiac conduction system axis. The cardiac effects of glucagon vary according to species, region, age, and concomitant disease. Depending on the species and region studied, the contractile effects of glucagon can be robust, modest, or even absent. Glucagon is detected in the mammalian heart and might act with an autocrine or paracrine effect on the cardiac glucagon receptors. The glucagon levels in the blood and glucagon receptor levels in the heart can change with disease or simultaneous drug application.

Main Metabolic Pathways with Respect to Alzheimer’s Disease
Alzheimer’s disease (AD) is an aging-related neurodegenerative disease, leading to the progressive loss of memory and other cognitive functions. Metabolomics allows the study of biochemical alterations in pathological processes which may be involved in AD progression and to discover new therapeutic targets. Metabolites are substrates, intermediates, and products of metabolic body processes, which typically are small molecules with a molecular weight of less than ~1.5 kDa. Since low molecular weight metabolites are intermediates or end products of cellular metabolism, metabolomics, or the study of metabolism can be considered one of the core disciplines of systems biology. It can help in improving our understanding of changes in biochemical pathways, revealing crucial information that is closely related to human disease or therapeutic status.

Interventional Methods against Neuropathic Pain
Neuropathic pain affects more than one million people across the globe. The quality of life of people suffering from neuropathic pain has been considerably declining due to the unavailability of appropriate therapeutics. Available treatment options can only treat patients symptomatically, but they are associated with severe adverse side effects and the development of tolerance over prolonged use. Continuous efforts are evident, aiming to develop novel interventions with better efficacy instead of symptomatic treatment. Available pharmacotherapeutics are unable to manage pain on a long-term basis and patients are developing resistance and tolerance to pain management medications over time; therefore, it is necessary to investigate non-pharmacological or interventional approaches. Interventional treatments, including nerve blocks or surgeries for targeted drug delivery, or specific neural modulation, provide alternate strategies in refractory cases.

Bisphenol A and Obesity
Lines of evidence have shown the embryogenic and transgenerational impact of bisphenol A (BPA), an endocrine-disrupting chemical, on immune-metabolic alterations, inflammation, and oxidative stress, while BPA toxic effects in adult obese mice are still overlooked. Here, we evaluate BPA’s worsening effect on several hepatic maladaptive processes associated to high-fat diet (HFD)-induced obesity in mice. After 12 weeks HFD feeding, C57Bl/6J male mice were exposed daily to BPA (50 μg/kg per os) along with HFD for 3 weeks. Glucose tolerance and lipid metabolism were examined in serum and/or liver. Hepatic oxidative damage (reactive oxygen species, malondialdehyde, antioxidant enzymes), and mitochondrial respiratory capacity were evaluated. Moreover, liver damage progression and inflammatory/immune response were determined by histological and molecular analysis. BPA amplified HFD-induced alteration of key factors involved in glucose and lipid metabolism, liver triglycerides accumulation, and worsened mitochondrial dysfunction by increasing oxidative stress and reducing antioxidant defense. The exacerbation by BPA of hepatic immune-metabolic dysfunction induced by HFD was shown by increased toll-like receptor-4 and its downstream pathways (i.e., NF-kB and NLRP3 inflammasome) amplifying inflammatory cytokine transcription and promoting fibrosis progression.

Advice of Medicine Shortages in Europe
The following recommendations should be considered to handle the issue of drug shortages more effectively in Europe. Since drug shortages do not respect borders and cross-country collaboration would be beneficial for more effective shortage management, a unified European definition and reporting criteria of shortages would be necessary to assure internationally consistent monitoring, reporting, comparisons, responses, and solutions. National authorities across Europe should be aware of shortages through coordinated systems, increasing cross-country transparency, and facilitating solutions in every country. It was a significant step forward in the European Union that in July 2019, the EMA published the “Guidance on detection and notification of shortages of medicinal products for Marketing Authorisation Holders in the Union”. The document contains the effort to facilitate the more uniform reporting and communication of drug shortages and create a harmonization “drug shortage” definition. The document “Good practice guidance for communication to the public on medicines availability issues”contains communication guidelines for the national authorities and the EMA for patients and healthcare professionals.

Dipeptidyl Peptidase 4 Inhibitors
Information on absorption, metabolism and excretion of drugs is necessary to support the studies on their pharmacokinetics and potential drug–drug interactions. Moreover, the knowledge on drug metabolism is one of the crucial factors used to assess their pharmacokinetic profile in patients with some dysfunctions. It is especially important in diabetic patients with higher incidence of chronic liver and kidney problems.

Physiological Cooperation between Aquaporin 5 and TRPV4
Aquaporins—among them, AQP5—are responsible for transporting water across biological membranes, which is an important process in all living organisms. The transient receptor potential channel 4 (TRPV4) is a cation channel that is mostly calcium-permeable and can also be activated by osmotic stimuli. It plays a role in a number of different functions in the body, e.g., the development of bones and cartilage, and it is involved in the body’s osmoregulation, the generation of certain types of sensation (pain), and apoptosis. Earlier studies on the uterus and the literature data aroused the interest in the physiological role of the cooperation of AQP5 and TRPV4. Understanding the cooperation between AQP5 and TRPV4 may contribute to the development of new drug candidates and the therapy of several disorders (e.g., preterm birth, cataract, ischemia/reperfusion-induced edema, exercise- or cold-induced asthma).

Therapeutic Potential of Serotonin Type 7 Receptor Modulation
Although a number of mood-stabilising atypical antipsychotics and antidepressants modulate serotonin type 7 receptor (5-HT7), the detailed contributions of 5-HT7 function to clinical efficacy and pathophysiology have not been fully understood. The mood-stabilising antipsychotic agent, lurasidone, and the serotonin partial agonist reuptake inhibitor, vortioxetine, exhibit higher binding affinity to 5-HT7 than other conventional antipsychotics and antidepressants. The initially expected rapid onset of antidepressant effects—in comparison with conventional antidepressants or mood-stabilising antipsychotics—due to 5-HT7 inhibition has not been observed with lurasidone and vortioxetine; however, several clinical studies suggest that 5-HT7 inhibition likely contributes to quality of life of patients with schizophrenia and mood disorders via the improvement of cognition. Furthermore, it reported that 5-HT7 inhibition might mitigate antipsychotic-induced weight gain and metabolic complication by blocking other monoamine receptors. Further preclinical studies for the development of 5-HT7 modulation against neurodevelopmental disorders and neurodegenerative diseases have been ongoing. Various findings from various preclinical studies indicate the possibility that 5-HT7 modifications can provide two independent strategies. The first is that 5-HT7 inhibition ameliorates the dysfunction of inter-neuronal transmission in mature networks. The other is that activation of 5-HT7 can improve transmission dysfunction due to microstructure abnormality in the neurotransmission network—which could be unaffected by conventional therapeutic agents—via modulating intracellular signalling during the neurodevelopmental stage or via loss of neural networks with aging.

Natural Molecules for Neurodegenerative Diseases
Natural molecules with favorable safety profile and broad pharmacological activities have shown great promise in the treatment of various neurodegenerative diseases (NDDs). Studies applying natural molecules against NDDs mainly focus on well-recognized conventional pathogenesis, such as toxic protein aggregation, oxidative stress, and neuroinflammation. However, accumulating evidence reveals that some underlying pathogenic mechanisms are involved earlier and more deeply in the occurrence and development of NDDs, such as ferroptosis, energy metabolism disorders, autophagy-lysosomal dysfunction, endoplasmic reticulum stress, and gut dysbiosis. Therefore, determining whether natural molecules can play therapeutic roles in these emerging pathogenic mechanisms will help clarify the actual targets of natural molecules and their future clinical translation.

Autophagy in Uveal Melanoma
Autophagy is a form of programmed cell degradation that enables the maintenance of homeostasis in response to extracellular stress stimuli. Autophagy is primarily activated by starvation and mediates the degradation, removal, or recycling of cell cytoplasm, organelles, and intracellular components in eukaryotic cells. Autophagy is also involved in the pathogenesis of human diseases, including several cancers. Autophagy mechanisms and mediators have emerged as promising therapeutic targets that could be used to develop new treatment options for uveal melanoma (UM).

Cistus albidus L.
Cistus albidus is one of the approximately 20 species of the Cistus genus. The genus’ name is derived from the ancient Greek term kistos. It is supposed that the name alludes to the woody capsule fruits. Evergreen in its Mediterranean homeland and between 50 and 250 centimeters tall, this shrub is called albidus, not because of the colour of its flowers, but because its leaves are finely covered with white hair (trichomes).

Pyroptosis and Cancer
Pyroptosis is a programmed cell death characterized by the rupture of the plasma membranes and release of cellular content leading to inflammatory reaction. Four cellular mechanisms inducing pyroptosis have been reported, including the (i) caspase 1-mediated canonical, (ii) caspase 4/5/11-mediated non-canonical, (iii) caspase 3/8-mediated and (iv) caspase-independent pathways. Although discovered as a defense mechanism protecting cells from infections of intracellular pathogens, pyroptosis plays roles in tumor initiation, progression and metastasis of tumors, as well as in treatment response to antitumor drugs and, consequently, patient outcome. Pyroptosis induction following antitumor therapies has been reported in several tumor types, including lung, colorectal and gastric cancer, hepatocellular carcinoma and melanoma.
