The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA), also called ecstasy, is a neurotoxin widely consumed among young people that has increased in recent years because it is a recreational drug, of which immediate effects are known such as a greater sensation of well-being, extroversion, increased sensory perception. However, its long-term effects have been described very little in the medical literature, including damage to the heart, central nervous system, kidney, etc. One of its little-known effects is hepatotoxicity, of which few cases are known associated with fulminant hepatitis, which is a rapidly deteriorating condition that is generally associated with a syndrome of multiple organ dysfunction and death. Therefore, it is very important to know this type of damage in the short and long term. The following case is of a 39-year-old man who came to our service due to jaundice syndrome and the only history of MDMA consumption, who as the days went by met the criteria for fulminant liver failure, with damage to multiple organs (organ dysfunction syndrome).

The core promoter(CP) of the viral genome plays an important role for hepatitis B virus(HBV) replication as it directs initiation of transcription for the synthesis of both the precore and pregenomic(pg) RNAs. The CP consists of the upper regulatory region and the basa core promoter(BCP). The CP overlaps with the 3'-end of the X open reading frames and the 5'-end of the precore region,and contains cis-acting elements that can independently direct transcription of the precore mRNA and pgRNA. Its transcription regulation is under strict control of viral and cellular factors. Even though this regulatory region exhibits high sequence conservation,when variations appear,they may contribute to the persistence of HBV within the host,leading to chronic infection and cirrhosis,and eventually,hepatocellular carcinoma. Among CP sequence variations,those occurring at BCP may dysregulate viral gene expression with emphasis in the hepatitis B e antigen,and contribute to disease progression. In this review these molecular aspects and pathologic topics of core promoter are deeply evaluated.

We introduce a new algebraic approach dealing with the problem of computing the topology of an arrangement of a finite set of real algebraic plane curves presented implicitly. The main achievement of the presented method is a complete avoidance of irrational numbers that appear when using the sweeping method in the classical way for solving the problem at hand. Therefore, it is worth mentioning that the efficiency of the proposed method is only assured for low-degree curves.

Cardiovascular diseases are the main cause of morbidity and mortality in the world, and obesity and the metabolic syndrome are risk factors for its development. One of the therapies to reduce cardiovascular risk is the use of polyunsaturated fatty acids. In Brazil, a source of such acid is the oil extracted from the fat of the capybara. The objective of this work is to study the effects of the capybara oil on lipid and glucose metabolism, as well as its effects on the adipose tissue and cardiac remodeling. We assessed the effects of capybara oil treatment on body mass, lipid and carbohydrate metabolism, systolic blood pressure, adipose tissue and cardiac remodeling, and performed an ultrastructural evaluation of the myocardium in C57Bl/6 mice treated with high-fat diet. Treatment with capybara oil reduced total cholesterol and triglyceride levels, systolic blood pressure, visceral and subcutaneous adipose tissue, and adipocyte diameter. In addition, cardiac remodeling was attenuated, preserving cardiomyocytes, increasing vascularization, reducing cardiomyocyte hypertrophy and the extracellular matrix, and preserving the morphological integrity of mitochondria. Capybara oil has several beneficial effects on the cardiovascular and metabolic system, and further studies are needed to better understand its role in the prevention or treatment of cardiovascular diseases.

Varicoceles are a fountain of inspiration for male health providers since times immemorial, and it has haunted men ever since with so many different and multifaceted aspects that even today, basic scientists and andrologists are finding new and exciting discoveries derived from its pathophysiology, clinical outcomes, and consequences. Varicocele is a perfect model to link basic science with technological innovation in diagnostic testing in semen analysis and surgical techniques improving medical practice and improving male reproductive and general health.
