Arrhythmic Mitral Valve Prolapse
Mitral valve prolapse (MVP) is a common cause of valvular heart disease. Although many patients with MVP have a benign course, there is increasing recognition of an arrhythmic phenotype associated with ventricular arrhythmias and sudden cardiac death (SCD). Pathophysiologic mechanisms associated with arrhythmias include cardiac fibrosis, mechanical stress induced changes in ventricular refractory periods, as well as electrophysiologic changes in Purkinje fibers.

Arrhythmogenic Cardiomyopathy across the Spectrum of Ventricular Involvement
Improved disease recognition through family screening and increased life expectancy with appropriate sudden cardiac death prevention has increased the burden of heart failure in arrhythmogenic cardiomyopathy (ACM). Heart failure management guidelines are well established but primarily focus on left ventricle function. A significant proportion of patients with ACM have predominant or isolated right ventricle (RV) dysfunction. Management of RV dysfunction in ACM lacks evidence but requires special considerations across the spectrum of heart failure regarding the initial diagnosis, subsequent management, monitoring for progression, and end-stage disease management.

Arsenic Induced Neurotoxicity
Arsenic is a ubiquitous environmental contaminant widely distributed in the surrounding environmental compartments. Exposure to inorganic arsenic is known to cause major neurological effects such as cytotoxicity, chromosomal aberration, damage to cellular DNA and genotoxicity. On the other hand, long-term exposure to arsenic may cause neurobehavioral effects in the juvenile stage, which may have detrimental effects in the later stages of life. Thus, it is important to understand the toxicology and underlying molecular mechanism of arsenic which will help to mitigate its detrimental effects.

Arsenic metabolism, excretion, and toxicity
       Arsenic is a global, naturally present pollutant found in drinking water that is consumed by millions of people throughout the world. Humans have evolved an arsenic methyltransferase present in high levels in the liver to expedite its excretion from the body. Most organisms have this enzyme. The enzyme generates monomethyl (MMA) and dimethyl arsenic (DMA). These methylated species are considered more toxic than arsenite, but they bind less tightly to proteins and thereby are excreted more rapidly from the body. Individuals who have been chronically exposed to arsenite were found to possess advantageous genotypes to metabolize arsenites. However, higher expression of AS3MT was found to yield more toxic MMA but lower amounts were still capable of metabolizing arsenite to DMA. This likely reflects the complex metabolic processes involving not only AS3MT, but antioxidants and upstream regulators of AS3MT, potentially transcription factor NRF2. This article discusses arsenic metabolism, excretion, toxicity, and the evolution of this enzyme across various species. The fact that so many organisms have evolved to possess this arsenite metabolizing enzyme is indicative of the widespread and ancient pollution of our drinking water by arsenite.

Arsenic-induced Health Hazards
Arsenic (As) is a naturally found crystalline metalloid with ubiquitous distribution throughout the earth’s crust. As exposure to the human food chain ecosystem comprises air, water, food, and soil. Daily diet contamination depends on the inorganic or organic forms, oxidation state, water solubility, and food matrix. The differentiation and categorization of different foods as sources of inorganic and organic As contamination in daily life is an important issue.

Art Therapy
Art therapy (not to be confused with arts therapy, which includes other creative therapies such as drama therapy and music therapy) is a distinct discipline that incorporates creative methods of expression through visual art media. Art therapy, as a creative arts therapy profession, originated in the fields of art and psychotherapy and may vary in definition. There are three main ways that art therapy is employed. The first one is called analytic art therapy. Analytic art therapy is based on the theories that come from analytical psychology, and in more cases, psychoanalysis. Analytic art therapy focuses on the client, the therapist, and the ideas that are transferred between the both of them through art. Another way that art therapy is utilized is art psychotherapy. This approach focuses more on the psychotherapist and their analysis of their clients artwork verbally. The last way art therapy is looked at is through the lens of art as therapy. Some art therapists practicing art as therapy believe that analyzing the client’s artwork verbally is not essential, therefore they stress the creation process of the art instead. In all of these different approaches to art therapy, the art therapist's client goes on the journey to delve into their inner thoughts and emotions by the use of paint, paper and pen, clay, sand, or maybe even fabric. Art therapy can be used to help people improve cognitive and sensory motor function, self-esteem, self awareness, emotional resilience. It may also aide in resolving conflicts and reduce distress. Current art therapy includes a vast number of other approaches such as person-centered, cognitive, behavior, Gestalt, narrative, Adlerian, and family. The tenets of art therapy involve humanism, creativity, reconciling emotional conflicts, fostering self-awareness, and personal growth.

Artemisia absinthium L.
Artemisia absinthium – wormwood (Asteraceae) – is a very important species in the history of medicine, formerly described in medieval Europe as “the most important master against all exhaustions”. It is a species known as a medicinal plant in Europe and also in West Asia and North America. The raw material obtained from this species is Artemisiae herba and Artemisiae absinthium aetheroleum. The main substances responsible for the biological activity of the herb are: the essential oil, bitter sesquiterpenoid lactones, flavonoids, another bitterness-imparting compounds, azulenes, phenolic acids, tannins and lignans. In the official European medicine, the species is used in both allopathy and homeopathy. In the traditional Asian and European medicine, it has been used as an effective agent in gastrointestinal ailments and also in the treatment of helminthiasis, anaemia, insomnia, bladder diseases, difficult-to-heal wounds, and fever. Today, numerous other directions of biological activity of the components of this species have been demonstrated and confirmed by scientific research, antiprotozoal, antibacterial, antifungal, anti-ulcer, hepatoprotective, anti-inflammatory, immunostimulatory, cytotoxic, analgesic, neuroprotective, antidepressant, procognitive, neurotrophic, and cell membrane stabilizing activities. A. absinthium is also making a successful career as a cosmetic plant. In addition, the importance of this species as a spice plant and valuable additive in the alcohol industry (famous absinthe and vermouth-type wines) has not decreased. The species has also become an object of biotechnological research.

Artemisia-AgNPs Applicaton in cancer nanomedicine
The fight against cancer is one of the main challenges for medical research. Recently, nanotechnology has made significant progress, providing possibilities for developing innovative nanomaterials to overcome the common limitations of current therapies. In this context, silver nanoparticles (AgNPs) represent a promising nano-tool able to offer interesting applications for cancer research. Following this path, we combined the silver proprieties with Artemisia arborescens characteristics, producing novel nanoparticles called Artemisia–AgNPs. A “green” synthesis method was performed to produce Artemisia–AgNPs, using Artemisia arborescens extracts. Several biological assays were performed to evaluate the Artemisia–AgNPs anti-cancer properties.

Arterial Hypertension and DNA Sequencing
Despite constant progress in understanding its pathology and associated therapeutic actions by targeting lifestyle changes and novel drug treatment strategies, arterial hypertension currently represents one of the major causes of cardiovascular morbidity and mortality in Europe, with severe potential complications. Significant distinct individual variations of responses to antihypertensive therapy suggest that genetic analysis may provide new important data regarding an accurate definition of prognosis and, most significantly, an adequate choice of treatment, therefore preventing potential complications. Data regarding the multifactorial genetic inheritance of essential arterial hypertension have long been considered; however, given the current rise of genetics and genomics, DNA sequencing could represent a step toward specific genetic variation-based therapy in hypertensive patients with uncontrolled blood pressure, despite standard antihypertensive treatment.
