Cardioprotective Role of Vascular Endothelial Growth Factor B
Coronary heart disease (CHD) is the leading cause of death around the world. Based on the roles of vascular endothelial growth factor (VEGF) family members to regulate blood and lymphatic vessels and metabolic functions, several therapeutic approaches have been attempted. However proangiogenic therapies based on classical VEGF-A have been disappointing. Therefore, it has become important to focus on other VEGFs, like VEGF-B, which is a novel member of the VEGF family.

Mechanisms of CLL Cell Stimulation via BcR
The engagement of the B cell receptor (BcR) on the surface of leukemic cells represents a key event in chronic lymphocytic leukemia (CLL) since it can lead to the maintenance and expansion of the neoplastic clone. This notion was initially suggested by observations of the CLL BcR repertoire and of correlations existing between certain BcR features and the clinical outcomes of single patients. Based on these observations, tyrosine kinase inhibitors (TKIs), which block BcR signaling, have been introduced in therapy with the aim of inhibiting CLL cell clonal expansion and of controlling the disease. Indeed, the impressive results obtained with these compounds provided further proof of the role of BcR in CLL.

RSTS
The Rubinstein-Taybi syndrome (RSTS) is a rare congenital developmental disorder characterized by a typical facial dysmorphism, distal limb abnormalities, intellectual disability, and many additional phenotypical features. It occurs at between 1/100,000 and 1/125,000 births.

Sleep Stages Detection Using DL
Sleep is vital for one’s general well-being, but is often neglected, which has led to an increase in sleep disorders worldwide. Indicators of sleep disorders, such as sleep interruptions, extreme daytime drowsiness, or snoring, can be detected with sleep analysis. However, sleep analysis relies on visuals conducted by experts, and is susceptible to inter- and intra-observer variabilities. One way to overcome these limitations is to support experts with a programmed diagnostic tool (PDT) based on artificial intelligence for timely detection of sleep disturbances. Artificial intelligence technology, such as deep learning (DL), ensures that data are fully utilized with low to no information loss during training.

3D Pancreatic Cancer Models
Pancreatic cancer is an extremely lethal malignancy with a survival rate lower than any other cancer type. For decades, two-dimensional (2D) cultures have been the cornerstone for studying cancer cell biology and drug testing, due to their simplicity and cost. However, their inability to reconstitute the tumor architecture, the absence of nutrient and oxygen supply gradients, as well as the lack of appropriate mechano-forces that mimic the extracellular microenvironment, make them an inadequate model to accurately reproduce tissue level-specific characteristics. Bioengineering systems, such as three-dimensional (3D) patient-specific models, are progressively emerging as systems better able to mimic the biology of pancreatic tumors and to test new anticancer therapies, as they more efficiently recapitulate the complex tumor microenvironment characteristic of pancreatic tumors.

Trypanothione Reductase: Structural Analysis for Drug Discovery
Leishmaniasis, Chagas disease, and human African trypanosomiasis (HAT), also known as sleeping sickness, are vector borne zoonosis that affect millions of people worldwide and lead to the death of about 100,000 humans per year. Among several molecular targets proposed, trypanothione reductase (TR) is of particular interest for its critical role in controlling the parasite’s redox homeostasis.

Bile Acids in Metabolic Disease
Bile acids are cholesterol-derived metabolites with a well-established role in the digestion and absorption of dietary fat. More recently, the discovery of bile acids as natural ligands for the nuclear farnesoid X receptor (FXR) and membrane Takeda G-protein-coupled receptor 5 (TGR5), and the recognition of the effects of FXR and TGR5 signaling have led to a paradigm shift in knowledge regarding bile acid physiology and metabolic health. Bile acids are now recognized as signaling molecules that orchestrate blood glucose, lipid and energy metabolism. Changes in FXR and/or TGR5 signaling modulates the secretion of gastrointestinal hormones including glucagon-like peptide-1 (GLP-1) and peptide YY (PYY), hepatic gluconeogenesis, glycogen synthesis, energy expenditure, and the composition of the gut microbiome.

Salvia miltiorrhiza
Salvia miltiorrhiza Bunge, also known as red sage, is a valued herbal plant in the traditional medicine in Korea, China and Japan. It is called as Dansam in Korea, Danshen in China. It is well known for its highly medicinal properties in treating of heart and vascular diseases, chronic renal failure, Alzheimer’s disease, hepatitis and so forth. Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.

Neutrophil
Neutrophils represent about 50–70% of all white blood cells in the human circulation and are widely recognized as the first line of defense in infectious disease. However, neutrophils also have a clear modulatory role in human diseases such as cancer, respiratory disease, and autoimmunity. Infections and/or any inflammatory signals trigger a rapid influx of neutrophils from the peripheral blood to the inflammatory site, where they can utilize a broad variety of effector functions to.  Neutrophils are well known phagocytic cells, engulfing microorganisms or in case of bigger targets, such as cancer cells, taking “bites” of the membrane in a process called ‘trogocytosis’. Moreover, neutrophils are armed with granules that are loaded with proteases and inflammatory mediators  that are released upon activation. In addition, during a so called ‘oxidative burst’ neutrophils release high levels of  reactive oxygen species (ROS), which can trigger cell death of the target cell. Finally, neutrophils can entrap foreign materials in so called ‘neutrophil extracellular traps’ (NETs), which are mainly composed of neutrophil DNA and Granular contents. The effector functions of neutrophils can be triggered by antibodies that activate  neutrophils by binding to Fc-receptors (FcRs), leading to antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). Although neutrophils are mainly involved in innate immunity, neutrophils contribute to adaptive immune responses.
