Salivary glands produce a bicarbonate-rich fluid containing digestive and protective proteins and other components to be delivered into the gastrointestinal tract. Its function is under strict control of the autonomic nervous system. Salivary electrolyte and fluid secretion is primarily controlled by parasympathetic activity, while protein secretion is primaily triggered by sympathetic stimulation. Stress activates the hypothalamic - pituitary - adrenal axis. The peripheral limb of this axis is the efferent sympathetic/adrenomedullary system...

Animal models have been the main resources for drug discovery and prediction of drugs' pharmacokinetic responses in the body. However, noticeable drawbacks associated with animal models include high cost, low reproducibility, low physiological similarity to humans, and ethical problems. Engineered tissue models have recently emerged as an alternative or substitute for animal models in drug discovery and testing and disease modeling. In this review, we focus on skeletal muscle and cardiac muscle tissues by first describing their characterization and physiology...

BACKGROUND: The importance of hemoproteins for life lies largely in their iron-mediated chemical properties. In the human body, there are about 4 g of iron, a precious resource preserved by sophisticated recycling mechanisms. Iron is also important for pathogen growth, so it is not surprising that immune cells developed mechanisms to reduce iron availability in cases of inflammation. In healthy conditions, macrophages degrade hemoproteins and export iron, while if inflammation develops, they retain cytoplasmic iron to reduce extracellular iron concentrations...

The prevalence of hypertension (HTN) worldwide is high and is constantly rising. HTN is considered to be a silent killer since often there are no obvious symptoms but long-term, HTN significantly increases the risk of coronary heart disease and cerebrovascular diseases. Those with diagnosed HTN or at high risk of its development, should start blood pressure (BP) lowering therapy based on natural methods including: lifestyle, regular physical activity, respiratory training, reducing body mass, lowering sodium intake with food, potassium supplementation, balanced diet enriched with herbs, reducing caffeine and alcohol intake, smoking cessation, stress avoidance and regular monitoring of the BP...

Exploring a new target for antibacterial drug discovery has gained much attention because of the emergence of Multidrug Resistance (MDR) strains of bacteria. To overcome this problem the development of novel antibacterial was considered as highest priority task and was one of the biggest challenges since multiple factors were involved. The bacterial peptidoglycan biosynthetic pathway has been well documented in the last few years and has been found to be an imperative source for the development of novel antibacterial agents with high target specificity as they are essential for bacterial survival and have no homologs in humans...

Osteosarcoma is the most frequent primitive malignant bone tumor affecting adolescents and young adults worldwide. The tumor exhibits aggressive growth in the primary site and readily metastasizes to other organs. There has been no significant improvement in the 5-year survival rate since the 1970s and the figure remains at 60-70%. In addition, the side effects of chemotherapeutic drugs and resistance to chemotherapy compromise the effects of treatment for osteosarcoma. In recent years, the development of flavonoids drugs inhibiting carcinogenesis is attracting great interest in the scientific community...

Parkinsonian-like state was generated in mice by the administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to study the effects of Atremorine in Parkinson's disease (PD) related neuropathology and behavior deficits. This devastating disease is caused by the progressive degeneration of dopaminergic neurons in the substantia nigra. Numerous therapeutic strategies have been developed to protect neuronal damage, although no effective treatment for PD has been validated yet. This study tested the preventive and therapeutic neuroprotective effect of Atremorine on MPTP parkinsonian mouse model...

Chronic pain is among the most disabling and costly disorders, with prevalence ranging from 10% to 55%. However, current therapeutic strategies for chronic pain are unsatisfactory due to our poor understanding of its mechanisms. Thus, novel therapeutic targets need to be found in order to improve these patients' quality of life. PI3K and its downstream Akt are widely expressed in the spinal cord, particularly in the laminae I-IV of the dorsal horn, where nociceptive C and Aδ fibers of primary afferents principally terminate...

BACKGROUND: Heme Oxygenase-1 (HO-1) is a metabolic enzyme strongly involved in processes including cytoprotection, modulation of inflammatory response, anti-oxidative functions, regulation of cellular proliferation, angiogenesis, cardiovascular homeostasis, and immuno-modulation. HO-1 induction and/or activation is able to counterbalance, at least in part, oxidative stress and inflammation. For this reason, HO-1 can be regarded as an attractive target to ameliorate different stress-related pathologies...
