REVIEW
Noah A Kolb, Christopher R Trevino, Waqar Waheed, Fatemeh Sobhani, Kara K Landry, Alissa A Thomas, Mike Hehir
Immune checkpoint inhibitor (ICPI) therapy unleashes the body's natural immune system to fight cancer. ICPIs improve overall cancer survival, however the unbridling of the immune system may induce a variety of immune related adverse events. Neuromuscular immune complications are rare but they can be severe. Myasthenia gravis and inflammatory neuropathy are the most common neuromuscular adverse events but a variety of others including inflammatory myopathy are reported. The pathophysiologic mechanism of these autoimmune disorders may differ from that of non-ICPI related immune diseases...

REVIEW
Christina Braunsdorf, Salomé LeibundGut-Landmann
The incidence of human infections caused by the opportunistic fungal pathogen Candida albicans is on the rise due to increasing numbers of immunosuppressed patients. The importance of the immune system in preventing overgrowth of the colonizing fungus and thereby limiting infection is well recognized and host protective mechanisms widely investigated. Only recently, it was recognized that the natural diversity in the fungal species could also influence the outcome of the interaction between the fungus and the host...

REVIEW
Sumaira Ali, Gavin P McStay
The mitochondrial network is a dynamic organization within eukaryotic cells that participates in a variety of essential cellular processes, such as adenosine triphosphate (ATP) synthesis, central metabolism, apoptosis and inflammation. The mitochondrial network is balanced between rates of fusion and fission that respond to pathophysiologic signals to coordinate appropriate mitochondrial processes. Mitochondrial fusion and fission are regulated by proteins that either reside in or translocate to the inner or outer mitochondrial membranes or are soluble in the inter-membrane space...

PURPOSE OF REVIEW: Given the extremely expensive nature of critical care medicine, it seems logical that intensivists should play an active role in designing efficient systems of care. The true value of intensivists, however, is not well defined. RECENT FINDINGS: Anesthesiologists have taken key roles in improving patient safety in the operating room. Anesthesia-related mortality rates have decreased from 20 deaths per 100 000 anesthetics in the early 1980s to less than one death per 100 000 currently...

REVIEW
Haroon Khan, Surriya Amin, Seema Patel
Current therapies in clinical practice face strong criticism regarding their efficacy, and side effects, which forced the neuro-researchers to discover novel agents with different mechanistic insights. Glycosides are naturally-occurring plant secondary metabolites with significant medicinal potential and clinical scope as antidepressant. The aim of this review is to focus on the antidepressant effects of glycosides in preclinical studies, with an emphasis on the possible mechanisms. The literature search revealed that only a few phytoglycosides have been evaluated for their relevance in depression alleviation...

Early life nutritional exposures could modify the gene expression and susceptibility of allergic diseases (AD). This systematic review aimed to evaluate whether early life (the first 1,000 days) natural exposure to polyunsaturated fatty acids (PUFA) and ruminant trans fatty acids (R-TFA) could affect the AD risk. We searched PubMed, EMBASE, PsycINFO, Scopus, the Cochrane Library, and ClinicalTrials.gov from inception through September 10, 2017 for observational studies. The quality of studies was examined by the Newcastle-Ottawa Scale, and the best evidence synthesis (BES) was applied...

Antisense transcription is a widespread phenomenon in mammalian genomes, leading to production of RNAs molecules referred to as natural antisense transcripts (NATs). NATs apply diverse transcriptional and post-transcriptional regulatory mechanisms to carry out a wide variety of biological roles that are important for the normal functioning of living cells, but their dysfunctions can be associated with human diseases. In this review, we attempt to provide a molecular basis for the involvement of NATs in the etiology of human disorders such as cancers and neurodegenerative and cardiovascular diseases...

Previously, we reviewed how general cognitive processes might be susceptible to bias across both forensic and clinical fields, and how interdisciplinary comparisons could reduce error. We discuss several examples of clinical tasks which are heavily dependent on visual processing, comparing them to eyewitness identification (EI). We review the "constructive" nature of visual processing, and how contextual factors influence both medical experts and witnesses in decision making and recall. Overall, studies suggest common cognitive factors uniting these visual tasks, in both their strengths and shortcomings...

As the population in the industrialized world develops preference for what is perceived as a natural and holistic way of disease treatment, the popularity and the number of food supplements on the market, including herbal ones, is experiencing an unprecedented rise. However, unlike herbal medicinal products, intended for treating or preventing disease, current legislation classifies food supplements as products intended for achieving nutritional or physiological effect and to supplement the normal diet. Accordingly, most food supplements are not to be associated with specific health claims...

Endocannabinoid system is related with various physiological and cognitive processes including fertility, pregnancy, during pre- and postnatal development, pain-sensation, mood, appetite, and memory. In the latest decades, an important milestone concerning the endocannabinoid system was the discovery of the existence of the cannabinoid receptors CB1 and CB2. Anandamide was the first reported endogenous metabolite, which adjusted the release of some neurotransmitters through binding to the CB1 or CB2 receptors...

The hallmarks of tumor tissue are not only genetic aberrations but also the presence of metabolic and oxidative stress as a result of hypoxia and lactic acidosis. The stress activates several prosurvival pathways including metabolic remodeling, autophagy, antioxidant response, mitohormesis, and glutaminolysis, whose upregulation in tumors is associated with a poor survival of patients, while their activation in healthy tissue with statins, metformin, physical activity, and natural compounds prevents carcinogenesis...

BACKGROUND: Transfusion-transmitted malaria (TTM) is an accidental Plasmodium infection caused by whole blood or a blood component transfusion from a malaria infected donor to a recipient. Infected blood transfusions directly release malaria parasites in the recipient's bloodstream triggering the development of high risk complications, and potentially leading to a fatal outcome especially in individuals with no previous exposure to malaria or in immuno-compromised patients. A systematic review was conducted on TTM case reports in non-endemic areas to describe the epidemiological characteristics of blood donors and recipients...

Diego Vidal, Giorgio Olivo, Miquel Costas
Aliphatic C-H oxidation is the most attractive approach to functionalize hydrocarbon skeletons. The main challenge of this reaction is the control of regioselectivity since organic molecules contain multiple C-H bonds. This control is perfectly achieved in natural enzymes by means of a web of interactions that orient the substrate in a specific geometry and override intrinsic reactivity patterns. Replication of this control by combination of molecular catalysts and supramolecular recognition is highly desirable in this regard...
