Review
For decades, breast implants have been available for breast reconstructions and breast augmentations to improve the patients' health-related quality of life. Silicone implants (SI) have been used since the middle of the last century for breast reconstruction, for example after breast cancer, for birth defects, gender confirmation procedures, or for breast augmentation. Every year, several hundred SI are performed in Iceland for these purposes, but no central register is maintained. It can be estimated that at least 1000 - 3000 women have SI in Iceland and that around 300 Icelandic patients get SI every year. This informal review article discusses the so-called ASIA syndrome, the immunological effects of silicone and the possible relationship of SI to autoimmune diseases, symptoms, and diagnosis. In the methodology, this paper does not rely on the strict conditions of systematic reviews, but the authors relied only on peer-reviewed sources through PubMed, UpToDate and Scopus. The keywords used are silicon, silicon implant, silicon particles, immune response, autoimmunity, autoinflammation, Autoimmune/inflammatory syndrome induced by aduvants, ASIA, ASIA syndrome, breast implant illness. The paper reviews known facts about the disease, its characteristics, and statistical aspects.

Inflammation is an innate immunity protecting the body from pathogens and cellular damages and comprises two steps; 1) priming (preparatory step) and triggering (activation step). The key feature of the triggering step is the activation of inflammasomes that are intracellular protein complexes consisting of pattern recognition receptors and inflammatory molecules. Inflammasomes are activated in response to various ligands, leading to the caspase-1-mediated maturation and secretion of pro-inflammatory cytokines, IL-1β and IL-18 and the gasdermin D-mediated pyroptosis, an inflammatory form of cell death. Previous studies have demonstrated that inflammasome activation is a key determinant of inflammatory responses and many human diseases; therefore, inflammasomes have been attracted much attention as critical drug targets to prevent and treat various human diseases.

Review
Metabolic disturbances have been associated with many human diseases, including cancer, diabetes, and cardiovascular disease. Metabolomics, a rapidly growing member of the -omics family, investigates cellular metabolism by quantifying metabolites on a large scale and provides a link between metabolic pathways and the upstream genome that governs them. With the advances in analytical technologies, metabolomics is becoming a powerful tool for identifying diagnostic biomarkers of diseases, elucidating the pathological mechanisms, discovering novel drug targets, predicting drug responses, interpreting the mechanisms of drug action, as well as enabling precision treatment of patients. In this review, we highlight the recent advances of technologies and methodologies in metabolomics and their applications to the field of clinical pharmacology. Recent publications from 2013 to 2018 are covered in the review, and current challenges and potential future directions in the field are also discussed.

Review
As a multifactorial degenerative disease, Parkinson disease (PD) causes tremor, gait rigidity, and hypokinesia, which interfere with normal life. Because the disease is usually discovered in the late stage of complete degeneration of neurons, it can greatly delay treatment and even eventually lead to death. Therefore, the diagnosis of this disease is very challenging, and it is gratifying that substantial progress has been made in the development of optical coherence tomography (OCT) as a diagnostic biomarker for this disease, and genetic and imaging tests have become part of routine protocols in clinical practice. In the cognition of traditional Chinese medicine (TCM), this disease belongs to deficiency in origin and excess in superficiality, which is always caused by deficiency of liver and kidney, deficiency of qi and blood, and is closely related to wind, fire, phlegm and blood stasis. A large number of studies have shown that TCM can effectively treat motor and non-motor symptoms of PD, combat oxidative stress and reduce inflammatory response, and improve the quality of life of patients. Based on the pathophysiological mechanism of PD, this paper discusses the treatment of PD by TCM acupuncture combined with medicine based on syndrome differentiation.

Review
C1q is the recognition molecule of the classical pathway of the complement system. By binding to its targets, such as antigen-bound immunoglobulins or C-reactive protein, C1q contributes to the innate defense against infections. However, C1q also plays several other roles beyond its traditional role in complement activation. Circulating levels of C1q are determined in routine diagnostics as biomarker in several diseases. Decreased C1q levels are present in several autoimmune conditions. The decreased levels reflect the consumption of C1q by complement activation and serves as a biomarker for disease activity. In contrast, increased C1q levels are present in infectious and inflammatory diseases and may serve as a diagnostic biomarker. The increased levels of C1q are still incompletely understood but are suggested to modulate the adaptive immune response as C1q is known to impact on the maturation status of antigen-presenting cells and C1q impacts directly on T cells leading to decreased T-cell activity in high C1q conditions. In this review, we provide a comprehensive overview of the current literature on circulating levels of C1q in health and disease, and discuss how C1q can both protect against infections as well as maintain tolerance by regulating adaptive immunity.

Review
Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is a canonical receptor for oxidized LDL (oxLDL) among the known modified LDL particles. Topographical variance on LOX-1 expression in different cell types and its influence on the atherogenic potential of the particular cell type is the main focus of this review. Characteristic features of LOX-1 on the atherogenic potential of aortic endothelial cells, macrophages, platelets, and vascular smooth muscle cells have been discussed. Nonspecificity of ligands, besides oxLDL, is also the highlight of this review to show the chameleon characteristics in the functional activity of the receptor protein. Induction of LOX-1 has been reported in diseases like atherosclerosis, diabetes, and hypertension, as well as in the inflammatory response of immune reactions. The expression of LOX-1 is upregulated by the vicious cycle of stimulatory response from proatherogenic molecules.

Review
Clinical single-cell biomedicine has become a new emerging discipline, which integrates single-cell RNA and DNA sequencing, proteomics, and functions with clinical phenomes, therapeutic responses, and prognosis. It is of great value to discover disease-, phenome-, and therapy-specific diagnostic biomarkers and therapeutic targets on the basis of the principle of clinical single-cell biomedicine. This book reviews the roles of single-cell sequencing and methylation in diseases and explores disease-specific alterations of single-cell sequencing and methylation, especially focusing on potential applications of methodologies on human single-cell sequencing and methylation, on potential correlations between those changes with pulmonary diseases, and on potential roles of signaling pathways that cause heterogeneous cellular responses during treatment. This book also emphasizes the importance of methodologies in clinical practice and application, the potential of perspectives, challenges and solutions, and the significance of single-cell preparation standardization. Alterations of DNA and RNA methylation, demethylation in lung diseases, and a deep knowledge about the regulation and function of target gene methylation for diagnosing and treating diseases at the early stage are also provided. Importantly, this book aims to apply the measurement of single-cell sequencing and methylation for clinical diagnosis and treatment and to understand clinical values of those parameters and to headline and foresee the potential values of the application of single-cell sequencing in non-cancer diseases.

Review
Inflammation is vital to protect the host against foreign organism invasion and cellular damage. It requires tight and concise gene expression for regulation of pro- and anti-inflammatory gene expression in immune cells. Dysregulated immune responses caused by gene mutations and errors in post-transcriptional regulation can lead to chronic inflammatory diseases and cancer. The mechanisms underlying post-transcriptional gene expression regulation include mRNA splicing, mRNA export, mRNA localisation, mRNA stability, RNA/protein interaction, and post-translational events such as protein stability and modification. The majority of studies to date have focused on transcriptional control pathways. However, post-transcriptional regulation of mRNA in eukaryotes is equally important and related information is lacking. In this review, we will focus on the mechanisms involved in the pre-mRNA splicing events, mRNA surveillance, RNA degradation pathways, disorders or symptoms caused by mutations or errors in post-transcriptional regulation during innate immunity especially toll-like receptor mediated pathways.

Review
Leukotriene B4 (LTB4) is a major type of lipid mediator that is rapidly generated from arachidonic acid through sequential action of 5-lipoxygenase (5-LO), 5-lipoxygenase-activating protein (FLAP) and LTA4 hydrolase (LTA4H) in response to various stimuli. LTB4 is well known to be a chemoattractant for leukocytes, particularly neutrophils, via interaction with its high-affinity receptor BLT1. Extensive attention has been paid to the role of the LTB4-BLT1 axis in acute and chronic inflammatory diseases, such as infectious diseases, allergy, autoimmune diseases, and metabolic disease via mediating recruitment and/or activation of different types of inflammatory cells depending on different stages or the nature of inflammatory response. Recent studies also demonstrated that LTB4 acts on non-immune cells via BLT1 to initiate and/or amplify pathological inflammation in various tissues. In addition, emerging evidence reveals a complex role of the LTB4-BLT1 axis in cancer, either tumor-inhibitory or tumor-promoting, depending on the different target cells. In this review, we summarize both established understanding and the most recent progress in our knowledge about the LTB4-BLT1 axis in host defense, inflammatory diseases and cancer.

Review
Apathy is commonly defined as a loss of motivation leading to a reduction in goal-directed behaviors. This multidimensional syndrome, which includes cognitive, emotional and behavioral components, is one of the most prevalent neuropsychiatric features of Parkinson's disease (PD). It has been established that the prevalence of apathy increases as PD progresses. However, the pathophysiology and anatomic substrate of this syndrome remain unclear. Apathy seems to be underpinned by impaired anatomical structures that link the prefrontal cortex with the limbic system. It can be encountered in the prodromal stage of the disease and in fluctuating PD patients receiving bilateral chronic subthalamic nucleus stimulation. In these stages, apathy may be considered as a disorder of motivation that embodies amotivational behavioral syndrome, is underpinned by combined dopaminergic and serotonergic denervation and is dopa-responsive. In contrast, in advanced PD patients, apathy may be considered as cognitive apathy that announces cognitive decline and PD dementia, is underpinned by diffuse neurotransmitter system dysfunction and Lewy pathology spreading and is no longer dopa-responsive. In this review, we discuss the clinical patterns of apathy and their treatment, the neurobiological basis of apathy, the potential role of the anatomical structures involved and the pathways in motivational and cognitive apathy.
