The Disease of Sympathetic Overdrive (DSO)
The sympathetic nervous system (SNS) is one of components of the autonomic system (ANS), whose overall ultimate function is to prepare the body for activities, which is a systemic response that affects many organs and systems. Accumulating evidence suggests that the SNS plays a crucial role in human numerous diseases. In the present article, we review the SNS dysfunction and even the disease of sympathetic overdrive (DSO) impact on cardiovascular, digestive, endocrine and metabolic as well as mental nervous system and various systems of the body. Despite the fact that the existence of this disease has not been truly recognized and confirmed. Here we proposed a hypothesis of the disease as DSO for the first time. The aim of the study is identifying the framework of the DSO, including the risk-factors, symptoms, end-points, mechanisms, and the strategies of management in order to improve both of the theory and clinical practice.As the hypothesis of DSO is novel born , the enrichment and improvement of hypothesis of the DSO are surely needed.

Leaching Chalcocite in Chloride Media
Chalcocite is the most abundant secondary copper sulfide globally, with the highest copper content, and is easily treated by conventional hydrometallurgical processes, making it a very profitable mineral for extraction. Among the various leaching processes to treat chalcocite, chloride media show better results and have a greater industrial boom. Chalcocite dissolution is a two-stage process, the second being much slower than the first. During the second stage, in the first instance, it is possible to oxidize the covellite in a wide range of chloride concentrations or redox potentials (up to 75% extraction of Cu). Subsequently, CuS2 is formed, which is to be oxidized. It is necessary to work at high concentrations of chloride (>2.5 mol/L) and/or increase the temperature to reach a redox potential of over 650 mV, which in turn decreases the thickness of the elemental sulfur layer on the mineral surface, facilitating chloride ions to generate a better porosity of this.

Epilepsy
Epilepsy is a common brain disease characterized as a long-lasting propensity to engender epileptic seizures. These are defined by the International League Against Epilepsy (ILAE), as a transient occurrence of signs and/or symptoms, due to abnormal excessive or synchronous neuronal activity in the brain. The ILAE also describes that patients with epilepsy, besides neurobiological problems, also face cognitive, psychological, and social issues. Epileptic seizures can be classified depending on the onset (focal, generalized or unknown) and depending on the etiology (genetic, structural, infectious, metabolic, immune, unknown, or with more than one etiology). Epileptogenesis is when a physiological and functional brain develops recurrent and unprovoked seizures, due to abnormal biological alterations. Epileptogenesis encompasses: The moment a precipitating injury (such as stroke or traumatic brain injury) or event (as status epilepticus (SE) or febrile seizure) occurs; the latent period between this epileptogenic insult and a modified epileptic brain (having spontaneous unprovoked seizures); and the mechanisms that occur during chronic epilepsy. Despite that the knowledge about the epileptogenesis process has significantly increased, most of the current drugs for epilepsy are used to treat symptoms, meaning to stop the seizures. These drugs, named AEDs, do not prevent or cure epilepsy. Therefore, finding drugs that work as antiepileptogenic, interreacting with the process of epilepsy development, is fundamental.

Structural Class of ARS Inhibitors
Aminoacyl-tRNA synthetases (ARSs) are essential enzymes that ligate amino acids to tRNAs and translate the genetic code during protein synthesis. Their function in pathogen-derived infectious diseases has been well established, which has led to the development of small molecule therapeutics. The applicability of ARS inhibitors for other human diseases, such as fibrosis, has recently been explored in the clinical setting. There are active studies to find small molecule therapeutics for cancers.

Cardiovascular Risk Stratification and Cancer
Cancer patients receiving a potentially cardiotoxic oncologic therapy have an increased risk of cardiovascular adverse events (CVAEs), especially in presence of concomitant arterial hypertension (AH). Therefore, cancer patients should be evaluated before, during and after cardiotoxic treatments, to early identify new-onset or worsening AH or CVAEs. An expert panel of oncology networks from Piedmont and Aosta Valley (North-Western Italy) aimed to provide recommendations to support health professionals in selecting the best management strategies for patients, considering the impact on outcome and the risk–benefit ratio of diagnostic/therapeutic tools.

Anticancer Effects of Selenium Compounds
The chemistry of selenium (Se) compounds is not a young field, since its beginning was in the first half of the 19th century. The first steps in this scope were initiated in 1836 by the then toxicologists, who discovered a Se metabolite, diethyl selenide, excreted by inhalation during research using inorganic selenium compounds on animals. Meanwhile, the first synthesis of selenium-containing (Se-containing) compounds took place in 1847, when ethylselenol was obtained. Since then, selenium chemistry has developed greatly and investigators have started to look at whether it can help with society’s health problems, including cancer. The high number of new cancer incidences and the associated mortality continue to be alarming, leading to the search for new therapies that would be more effective and less burdensome for patients. As there is evidence that Se compounds can have chemopreventive activity, studies have begun to establish whether these compounds can also affect already existing cancers. This review aims to discuss the different classes of Se-containing compounds, both organic and inorganic, natural and synthetic, and the mechanisms and molecular targets of their anticancer activity.

Methylmercury Neurotoxicity and Neuroinflammation
Methylmercury (MeHg) toxicity is a major environmental concern. In the aquatic reservoir, MeHg bioaccumulates along the food chain until it is consumed by riverine populations. The central nervous system is particularly susceptible to the deleterious effects of MeHg, as evidenced by clinical symptoms and histopathological changes in poisoned humans. In vitro and in vivo studies have been crucial in deciphering the molecular mechanisms underlying MeHg-induced neurotoxicity. A collection of cellular and molecular alterations including cytokine release, oxidative stress, mitochondrial dysfunction, Ca2+ and glutamate dyshomeostasis, and cell death mechanisms are important consequences of brain cells exposure to MeHg.

Chromatin Profiling Techniques
The genetic architecture of complex traits is multifactorial. Genome-wide association studies (GWASs) have identified risk loci for complex traits and diseases that are disproportionately located at the non-coding regions of the genome. On the other hand, we have just begun to understand the regulatory roles of the non-coding genome, making it challenging to precisely interpret the functions of non-coding variants associated with complex diseases. Additionally, the epigenome plays an active role in mediating cellular responses to fluctuations of sensory or environmental stimuli. However, it remains unclear how exactly non-coding elements associate with epigenetic modifications to regulate gene expression changes and mediate phenotypic outcomes. Therefore, finer interrogations of the human epigenomic landscape in associating with non-coding variants are warranted.

Robotics in Gastrointestinal Endoscopy
Recent advances in endoscopic technology allow clinicians to not only detect digestive diseases early, but also provide appropriate treatment. The development of various therapeutic endoscopic technologies has changed the paradigm in the treatment of gastrointestinal diseases, contributing greatly to improving the quality of life of patients. The application of robotics for gastrointestinal endoscopy improves the maneuverability and therapeutic ability of gastrointestinal endoscopists, but there are still technical limitations. With the development of minimally invasive endoscopic treatment, clinicians need more sophisticated and precise endoscopic instruments. Novel robotic systems are being developed for application in various clinical fields, to ultimately develop into minimally invasive robotic surgery to lower the risk to patients. Robots for endoscopic submucosal dissection, autonomous locomotive robotic colonoscopes, and robotic capsule endoscopes are currently being developed.

Physical Exercise and Saliva Composition
Salivary glands are exocrine organs that produce a large amount of fluid. Through the saliva, electrolytes and other substances are transferred from the inner of the glands to the oral cavity. The mean volume of the fluid is estimated to be 750 mL/day, which almost represents 20% of the overall plasma volume. Apart from the major salivary glands (2–5 mL/min), saliva is also secreted by several minor glands at a rate of 0.5 mL/min.

Treat Preeclampsia by Targeting NFĸB by Drugs
Preeclampsia (PE) is characterised by high levels and activity of the transcription factor Nuclear Factor kappa B (NFĸB) in the maternal blood and placental cells. This factor is responsible for the regulation of over 400 genes known to influence processes related to inflammation, apoptosis and angiogenesis, and cellular responses to oxidative stress and hypoxia. Although high NFĸB activity induces hypoxia and inflammation, which are beneficial for the process of implantation, NFĸB level should be reduced in the later stages of physiological pregnancy to favour maternal immunosuppression and maintain gestation. It is believed that the downregulation of NFĸB activity by pharmacotherapy might be a promising way to treat preeclampsia.
