Microglia, the resident immune cells in the brain, are the first responders to inflammation or injury in the central nervous system. Recent research has revealed microglia to be dynamic, capable of assuming both pro-inflammatory and anti-inflammatory phenotypes. Both M1 (pro-inflammatory) and M2 (pro-reparative) phenotypes play an important role in neuroinflammatory conditions such as perinatal brain injury, and exhibit differing functions in response to certain environmental stimuli. The modulation of microglial activation has been noted to confer neuroprotection thus suggesting microglia may have therapeutic potential in brain injury...

BACKGROUND: The atrocities in Syria have been covered in the four general medical weekly journals in the USA and the UK. Medical journal articles addressing political determinants of public health have rightly described and criticised the international community's failure to enforce humanitarian law while urging global bodies of power to ensure protection of civilians and civilian infrastructure and medical services. Discussions of the political influences on health of people in the occupied Palestinian territory (West Bank and Gaza Strip) seem to be considered politically out-of-bounds by some medical journals...

Diabetic cardiomyopathy (DCM) is characterized by left ventricular hypertrophy, myocardial fibrosis and diastolic dysfunction, which are uncorrelated with underlying coronary artery disease or hypertension. As an important metabolic organelle, mitochondria directly involve the process of cell growth, proliferation, signal transduction, apoptosis and so on. Recent studies have demonstrated a close correlation between the mitochondrial dysfunction and the pathogenesis of diabetic cardiomyopathy. The underlying effects of mitochondrial dysfunction in the progress of diabetic cardiomyopathy involve disturbed metabolism, oxidative stress, defective calcium handling, mitochondrial uncoupling, apoptosis, imbalance of mitochondrial quality control and regulation of MicroRNAs...

Diabetic nephropathy (DN) is the major cause of end-stage renal disease in diabetic patients. Zicao, a well-known Chinese traditional medicine, has attracted much attention due to its beneficial effects in various medical fields. In this study, we attempted to investigate the effects and mechanisms of action of acetylshikonin, the main ingredient of Zicao, on renal dysfunction in DN. Our results showed that administration with acetylshikonin not only decreased blood urea nitrogen, urine creatinine and the mean kidney-to-body weight ratio in streptozotocin-induced diabetic mice, but also restored the loss of body weight, whereas the blood glucose was not changed...

MRI has transformed from the theoretical, investigative realm to mainstream clinical medicine over the past four decades and has become a core component of the diagnostic toolbox in the practice of gastroenterology (GI). Its success is attributable to exquisite contrast and the ability to isolate specific proton species through the use of different pulse sequences (i.e., T1-weighted, T2-weighted, diffusion-weighted) and exploiting extracellular and hepatobiliary contrast agents. Consequently, MRI has gained preeminence in various GI clinical applications: liver and pancreatic lesion evaluation and detection, liver transplantation evaluation, pancreatitis evaluation, Crohn's disease evaluation (using MR enterography) rectal cancer staging and perianal fistula evaluation...

Dyspnea or breathlessness is a term primarily used in respiratory medicine. Nevertheless, in the last fifteen years, studies from other fields focus on the affective component of this complex phenomenon due to the frequent observation that psychological states can cause or be caused by dyspnea. Research so far shows that besides the biological component, dyspnea has a strong emotional and psychosocial determinant. This means that apart from its biological factors, dyspnea and its intensity are affected by emotions, personality, anxiety and depression, etc...

Background: New technologies can profoundly change the way we understand psychiatric pathologies and addictive disorders. New concepts are emerging with the development of more accurate means of collecting live data, computerized questionnaires, and the use of passive data. Digital phenotyping , a paradigmatic example, refers to the use of computerized measurement tools to capture the characteristics of different psychiatric disorders. Similarly, machine learning-a form of artificial intelligence-can improve the classification of patients based on patterns that clinicians have not always considered in the past...

Patients are increasingly being diagnosed with neuropathic diseases, but are rarely cured because of the loss of neurons in damaged tissues. This situation creates an urgent clinical need to develop alternative treatment strategies for effective repair and regeneration of injured or diseased tissues. Neural stem cells (NSCs), highly pluripotent cells with the ability of self-renewal and potential for multidirectional differentiation, provide a promising solution to meet this demand. However, some serious challenges remaining to be addressed are the regulation of implanted NSCs, tracking their fate, monitoring their interaction with and responsiveness to the tissue environment, and evaluating their treatment efficacy...
