In Advances in Medicine and Biology. Volume 128, the authors provide evidence that several families of GPCRs dynamically modulate microglial phenotypes and provide evidence that aberrations in G-protein coupled receptors-mediated signaling are prime contributors to a loss of homeostatic microglia states. A comprehensive landscape on the physiological conditions already known to be important for dendritic cell (DC) differentiation is included. Specifically: presenting stages of development of bone marrow stem cells; comparing the ontogeny of DCs in mice and humans; debating the differences between conventional DCs versus plasmacytoid DCs; highlighting that Langerhans cells (LCs) have different origins; discussing factors that may modulate the development of DC subsets; and emphasizing ontogenetic properties of DCs that make them different from monocytes and macrophages. Next, the authors review ex vivo and in vitro studies about the effects of human soluble fibrinogen molecule on blood components behavior and its effects at physiological and pathophysiological conditions, as well as in vitro studies conducted in experimental animal models. The tacrolimus (TAC) metabolism is reviewed in a separate study which proposes the TAC metabolism rate (C/D ratio) as a novel tool to assist physicians in risk stratification to individualize therapy in patients after (renal) transplantation. Continuing, the book postulates that modulation of nitric oxide (NO) concentrations at the maternal-fetal interface is relevant for maintaining early gestation due to failures in vascular adaptations. NO regulates vascular tone, angiogenesis, and cellular aggregation and adhesion, which are important functions in establishing and maintaining normal pregnancy. This book also presents the research and development of a collaborative, social-networked approach to train elementary and middle-school students so that the students can be aware of their bad sitting posture and timely improve it. Results show that the proposed approach and the developed posture training tools were very effective in improving teens posture.

The science of pain. John Walsh One night in May, my wife sat up in bed and said, 'I've got this awful pain just here.' She prodded her abdomen and made a face. 'It feels like something's really wrong.' Woozily noting that it was 2am, I asked what kind of pain it was. 'Like something's biting into me and won't stop,' she said. 'Hold on,' I said blearily, 'help is at hand.' I brought her a couple of ibuprofen with some water, which she downed, clutching my hand and waiting for the ache to subside. An hour later, she was sitting up in bed again, in real distress. 'It's worse now,' she said, 'really nasty. Can you phone thedoctor?' Miraculously, the family doctor answered the phone at 3am, listened to her recital of symptoms and concluded, 'It might be your appendix. Have you had yours taken out?' No, she hadn't. 'It could be appendicitis,' he surmised, 'but if it was dangerous you'd be in much worse pain than you're in. Go to the hospital in the morning, but for now, take some paracetamol and try to sleep.' Barely half an hour later, the balloon went up. She was awakened for the third time, but now with a pain so savage and uncontainable it made her howl like a tortured witch face down on a bonfire. The time for murmured assurances and spousal procrastination was over. I rang a local minicab, struggled into my clothes, bundled her into a dressing gown, and we sped to St Mary's Paddington at just before 4am. The flurry of action made the pain subside, if only through distraction, and we sat for hours while doctors brought forms to be filled, took her blood pressure and ran tests. A registrar poked a needle into my wife's wrist and said, 'Does that hurt? Does that? How about that?' before concluding: 'Impressive. You have a very high pain threshold.' The pain was from pancreatitis, brought on by rogue gallstones that had escaped from her gall bladder and made their way, like fleeing convicts, to a refuge in her pancreas, causing agony. She was given a course of antibiotics and, a month later, had an operation to remove her gall bladder. 'It's keyhole surgery,' said the surgeon breezily, 'so you'll be back to normal very soon. Some people feel well enough to take the bus home after the operation.' His optimism was misplaced. My lovely wife, she of the admirably high pain threshold, had to stay overnight, and came home the following day filled with painkillers; when they wore off, she writhed with suffering. After three days she rang the specialist, only to be told:'

Advances in Medicine and Biology. Volume 130 begins by discussing proton pump inhibitors (patented in 1979) that selectively target the H,K- ATPase of gastric parietal cells as a reliable therapeutic regimen for management of acid reflux disease and gastric bleeding. Around the same time, H. pylori was recognized as the main cause of peptic ulcer. The following chapter explores how common bile duct stones can be predicted and investigated. In addition, the management of proven ductal calculi is discussed in the preoperative, intraoperative and postoperative stages. The investigation of ductal stones is partly dependent upon patient presentation and liver function tests, but also on availability of imaging modality and surgical experience. Afterwards, the authors summarize the current knowledge regarding the toxic effects of STZ on mammalian DNA and chromosomes, putting emphasis on the most recent findings on this subject. At the chromosome level, STZ induces chromosomal aberrations (including those ones involving telomeric sequences), micronuclei and sister chromatid exchanges. A review of current state of knowledge of atmospheric parameters pathophysiological mechanisms and its cardiovascular risk effects is included. Additionally, some medical prevention strategies that can provide effective protection against the negative health effects of global climate change are presented. The authors go on to summarize the morphogenesis, 3D structure, and rearrangement of the IHBDs, as well as the cellular changes of cholangiocytes during development and regeneration. Recent advances based on gene targeting, lineage tracing, and threedimensional (3D) analysis of the liver tissue have improved our understanding of the IHBDs morphogenesis and regeneration. The goal of the concluding chapter is to describe the current educational preparation and scope of practice of pediatric advance practice providers (APPs) and provide guidelines with a new practice model as to how to successfully integrate APPs into the pediatric emergency department. The pediatric health care and role of an acute care APP has evolved significantly in the last few years, with APPs seeing patients ranging from non-urgent to all kinds of pediatric emergencies.

In Advances in Medicine and Biology. Volume 127, the authors discuss Parkinson's disease (PD), a neurological disorder characterized by the death of dopaminergic neurons in the substantia nigra pars compacta and reduced dopamine levels in the striatum. Currently, there are few pharmacological treatments for PD and although Levodopa has frequently been used, it is not a viable treatment option for all patients. Thus, this book presents experimental evidence supporting the claim that endocannabinoid signaling may represent a promising therapeutic target for PD, inducing a reduction in neurodegeneration with minimal psychotropic effects. Subsequently, it presents findings that free-hydroxyproline observed in a physiological system must be resulted from a degradation of protein molecules. Variations in free-hydroxyproline concentrations in the plasma and white muscle of fishes, with genetic differences in growth rates and with different feedings, could indicate differences in protein degradation rates for tissue remodeling and growth. Since the synthesis of the connective tissue framework of muscle is a rate-limiting step in muscle growth, the concentrations of white muscle free-hydroxyproline could be reliable for growth studies, as its levels are correlated with fish specific growth rates (SGR) and feed efficiency. Next, the authors analyze the results of umbilical hernia repair using Ventralex (R) Hernia Patch, a bilayer prosthesis. Preoperative characteristics, surgical procedure details, postoperative complications and recurrence rate were studied. An overview of the most up-to-date findings on the association of NGF with development of schizophrenia is presented, based on literature data as well as the authors own findings. The contributions of other research groups are provided and discussed in the context of prominent existing hypothesis of psychiatric disorder development. Afterwards, hernias are discussed as one of the most common reasons a primary care patient may need referral for surgical intervention. The emergence of next-generation prosthesis seeks to achieve the best possible integration into the tissues, improving their performance on all interfaces and avoiding complications. The authors exhibit a retrospective cohort study to assess the impact of 6-hour versus 4-hour HD sessions in end-stage renal disease (ESRD) patients treated with three times per week, daytime, in-center HD. Using data from a cohort of forty-three, stable chronic ESRD patients, the authors compared twenty-one patients undergoing 6-hour HD sessions with twenty-two patients on conventional 4-hour HD sessions. The following chapter begins with an introduction to collagen and the function of Hyp in the collagen molecule, followed by a description of sources of various Hyp fractions in tissues and body fluids. The effects of different toxins on various Hyp fractions in the serum and tissues are also discussed. Then, soy isoflavones or soy derivatives (supplements containing S-equol) are recommended for relieving vasomotor symptoms. The evidences for standardized cohosh preparations are effective and are also be recommended. This book also discusses DNA damage repair, a very important biological process commonly associated with human health and diseases, because a detailed elucidation of DNA repair mechanism is essential for a better understanding of health and disease. Afterwards, the current information on collagen PTMs and their alteration under different pathological conditions are examined. It has been reported that collagen undergoes polyubiquitination in response to S-adenosyl-L-methionine. The polyubiquitination inhibits Collagen processing leading to decreased collagen secretion in hepatic stellate cells (HSCs). In closing, a critical review about the impact of changes in lifestyle and diet supplementation with natural phytochemicals on cancer statistics is given. This review highlights the new advances in understanding the anticancer activity of flavonoids based on its ability to damage DNA in cancer cells.
