Multivariate regression showed that OTC abuse/misuse was associated to the knowledge of the effects of OTC [odds ratio/OR = 2.711, 95%Confidence Interval/CI 1.794-4.097, p less then 0.001]. On the contrary, the educational level appeared to be a protective factor [OR = 0.695, 95%CI 0.58-0.94, p = 0.016]. Although, according to our data, the phenomenon of OTC abuse appeared to be limited, increasing attention is needed because of possible underestimation and high-risk outcomes. Preventive strategies, including a simplified access to information, may play a key role in the limitation of OTC misuse.Radiation-induced heart disease (RIHD) is a significant cause of morbidity in breast and other mediastinal cancers. The many molecular and cellular patho-mechanisms that have a role in RIHD are not completely understood. Endothelial injury, oxidative stress, and inflammation, as well as endoplasmic reticulum and mitochondrial damage, are considered the primary causes of RIHD. Ferroptosis is a newly discovered type of cell death that results from iron-dependent lipid peroxide accumulation. As ferroptosis plays an important role in the pathogenesis of cardiovascular diseases, it seems that it has a significant effect on RIHD. It was recently shown that ionizing radiation (IR) generates severe ferroptosis, which is a critical component of Radiotherapy-mediated normal cell toxicity. These findings support the use of a ferroptosis inhibitor to reduce RIHD. In this perspective review, we summarize the role of ferroptosis in pathogens of cardiovascular disease and radiation toxicity, and we will introduce ferroptosis inhibitors as a new strategy to prevent or reduce RIHD.

Plants of the genus Euphorbia have long been used as traditional medicine in China, Europe, America, Turkey, India, Africa, Iran, and Pakistan for their great medicinal value and health benefits. Their stems, leaves, roots, and latex are widely used to treat respiratory infections, body and skin irritations, digestive disorders, inflammatory infections, body pain, snake or scorpion bites, pregnancy, sensory disturbances, microbial and anticancer diseases.

This review aims to provide updated information on the genus Euphorbia, including traditional medicinal uses, valuation and exploitation of medicinal plants, phytochemistry, botanical characterization, pharmacological and toxicological research focused on the medicinal properties of several Euphorbias in particular their antibacterial, anti-tumor, and cell manifestations, in addition to the effect of each isolated bioactive molecule from these species and their pharmacological use including preclinical evaluation of new drugs.

Many previous studies have validated many traditional uses of Euphorbia species. The latex of some Euphorbia species seems to be toxic however, studies dealing with the safety and quality of these species are still incomplete. Extensive studies are needed on the Euphorbia plants before they can be fully used in clinics as a potent drug candidate, as researchers are focusing mainly on diterpenoids and triterpenoids, while there are many other types of compounds that may possess new biological activities.

Excessive cytokine release during COVID-19 is related to increased morbidity and mortality. Several mechanisms are put forward for cytokine release syndrome during COVID-19. Here we have mentioned novel pathways. SARS-CoV-2 increases angiotensin II levels by rendering ACE2 nonfunctional. Angiotensin II causes cytokine release via AT1 and AT2 receptors. Moreover, angiotensin II potently stimulates the Na+/H+ exchanger (NHE). It is a pump found in the membranes of many cells that pumps Na+ inward and H+ outward. NHE has nine isoforms. NHE1 is the most common isoform found in endothelial cells and many cells. NHE is involved in keeping the intracellular pH within physiological limits. When the intracellular pH is acidic, NHE is activated, bringing the intracellular pH to physiological levels, ending its activity. Sustained NHE activity is highly pathological and causes many problems. Prolonged NHE activation in COVID-19 may cause a decrease in intracellular pH through H+ ion accumulation in the extracellular area and subsequent redox reactions. The activation reduces the intracellular K+ concentration and leads to Na+ and Ca2+ overload. Increased ROS can cause intense cytokine release by stimulating NF-κB and NLRP3 inflammasomes. Cytokines also cause overstimulation of NHE. As the intracellular pH decreases, SARS-CoV-2 rapidly infects new cells, increasing the viral load. This vicious circle increases morbidity and mortality in patients with COVID-19. On the other hand, SARS-CoV-2 interaction with NHE3 in intestinal tissue is different from other tissues. SARS-CoV-2 can trigger CRS via NHE3 inhibition by disrupting the intestinal microbiota. This review aimed to help develop new treatment models against SARS-CoV-2- induced CRS by revealing the possible effects of SARS-CoV-2 on the NHE.Defined by the World Health Organization as a global public health pandemic, coronavirus 2019 (COVID-19) has a global impact and has caused the death of thousands of people. The "severe acute respiratory syndrome coronavirus 2" virus (SARS-CoV-2) is the etiologic agent of this disease, which uses the angiotensinconverting enzyme receptor 2 (ACE2) to infect the body, so any organ that expresses the gene ACE2 is a possible target for the new coronavirus. In addition, in severe cases of COVID-19, a cytokine storm occurs, which triggers widespread systemic inflammation due to the uncontrolled release of proinflammatory cytokines. In this perspective, the modulation of purinergic receptors is highlighted in the literature as a possible therapy, considering its application in other viral infections and systemic inflammation. Therefore, this review aims to gather information on the modulation of the P2X7 receptor in the main organs directly affected by the virus and by the cytokine storm the heart, brain, lung, liver and kidneys. Thus, demonstrating possible therapies for reducing inflammation and the level of morbidity and mortality of COVID-19. In severe cases of COVID-19, SARS-CoV-2 infection is capable of triggering an exacerbated release of cytokines, called a cytokine storm. With this inflammation, or less the direct infection of the virus, the whole organism can be affected. In this way, major and important organs such as the heart, lung, brain, and liver are affected, triggering different pathologies. In this perspective, purinergic signaling is highlighted in the literature for its anti-inflammatory role and has been listed in the pandemic scenario as a potential therapy. Therefore, knowing the expression of the purinergic receptor P2X7 in these tissues, the modulation of its inflammatory activity may be favorable in this severe and systemic condition.

Cancer is the biggest killer that threatens human health. Poor bioavailability and strong drug resistance of cancer drugs are common defects. In recent years, drug delivery therapy based on nanotechnology has become a focused research area, and nano drug delivery system has been widely studied in cancer treatment.

Future research on nano drug delivery system should consider its potential risks, and design stable and efficient nano drug delivery system to treat cancer by changing nanomaterials or functionalizing nanomaterials.

The discovery of Kaposi sarcoma herpesvirus (KSHV) / human herpesvirus 8 (HHV-8) led to recognition of primary effusion lymphoma (PEL) as a distinct lymphoproliferative disorder. Subsequently, two other types of lymphoma have been shown to be associated with HHV-8 HHV-8 positive diffuse large B cell lymphoma not otherwise specified and germinotropic lymphoproliferative disorder.The pathogenesis of PEL is unique as in most cases the HHV-8+ tumoral cells are coinfected with the Epstein-Barr virus (EBV), suggesting an interplay between these two herpesviruses. This article reviews advances in the field of characterization of the lymphomatous cells, pathogenesis, and targeted therapies.

The gene expression profile analysis of PEL cells and the experimental coinfection of peripheral B cells with HHV-8 and EBV allow dissection of the mechanisms of lymphomagenesis and of the relative contribution of both viruses. Systemic chemotherapy regimen remains poorly effective but new therapeutic perspectives are open with the use of monoclonal antibodies, immunomodulatory drugs, and immunotherapy.
