Recent studies have highlighted the fact that the enteric microbiome, the trillions of microbes that inhabit the human digestive tract, has a significant effect on health and disease. Methods for manipulating the enteric microbiome, particularly through probiotics and microbial ecosystem transplantation, have undergone some study in clinical trials. We review some of the evidence for microbiome alteration in relation to childhood disease and discuss the clinical trials that have examined the manipulation of the microbiome in an effort to prevent or treat childhood disease with a primary focus on probiotics, prebiotics, and/or synbiotics (ie, probiotics + prebiotics)...

There has been a continued interest in translational research focused on both natural products and manipulation of functional groups on these compounds to create novel derivatives with higher desired activities. Oleanolic acid, a component of traditional Chinese medicine used in hepatitis therapy, was modified by chemical processes to form 2-cyano-3,12-dioxoolean-1,9-dien-28-oic acid (CDDO). This modification increased anti-inflammatory activity significantly and additional functional groups on the CDDO backbone have shown promise in treating conditions ranging from kidney disease to obesity to diabetes...

Obesity is a crescent epidemic in the world, affecting more than half a billion of adults worldwide. Obesity is associated to main cardiovascular risk factors, such as insulin resistance, type 2 diabetes mellitus, high blood pressure and dyslipidemia. The excessive adiposity causes a dysregulation of adipokines secretion by adipose tissue, upregulating the expression of pro-inflammatory adipokines and downregulating the anti-inflammatory ones. This scenario contributes for the appearance of atherosclerosis...

Bariatric surgery, initially intended as a weight-loss procedure, is superior to standard lifestyle intervention and pharmacological therapy for type 2 diabetes in obese individuals. Intensive medical management of hyperglycemia is associated with improved microvascular outcomes. Whether or not the reduction in hyperglycemia observed after bariatric surgery translates to improved microvascular outcomes is yet to be determined. There is substantial heterogeneity in the data relating to the impact of bariatric surgery on diabetic retinopathy (DR), the most common microvascular complication of diabetes...

Neuroinflammation is a pathological condition that underlies diabetes and affects sensory processing. Given the high prevalence of pain in diabetic patients and crosstalk between chemokines and opioids, it is pivotal to know whether neuroinflammation-associated mediators are dysregulated in the central nervous system of diabetic primates. Therefore, the aim of this study was to investigate whether mRNA expression levels of glial markers, chemokines, and opioid receptors are altered in the spinal cord and thalamus of naturally occurring type 2 diabetic monkeys (n=7) compared with age-matched non-diabetic monkeys (n=6)...

Glycosaminoglycans (GAGs) are long blocks of negatively charged polysaccharides. They are one of the major components of the extracellular matrix and play multiple roles in different tissues and organs. The accumulation of undegraded GAGs causes mucopolysaccharidoses (MPS). GAGs are associated with other pathological conditions such as osteoarthritis, inflammation, diabetes mellitus, spinal cord injury, and cancer. The need for further understanding of GAG functions and mechanisms of action boosted the development of qualitative and quantitative (alcian blue, toluidine blue, paper and thin layer chromatography, gas chromatography, high pressure liquid chromatography, capillary electrophoresis, 1,9-dimethylmethylene blue, enzyme linked-immunosorbent assay, mass spectrometry) techniques...

Accelerating diabetes rates have resulted in a global public health epidemic. Lifestyle change is a cornerstone of care, yet regimen demands may result in adherence difficulties. Distress, depression, and other psychosocial concerns are higher in those with diabetes. While interventions, such as the Diabetes Prevention Program appear to be effective, further research is needed to support the translation of interventions to prevent diabetes. Studies assessing optimal approaches to promoting effective decision making, coping and adherence are needed...

Transplantation of alginate-encapsulated islets has the potential to treat patients suffering from type I diabetes, a condition characterized by an autoimmune attack against insulin-secreting beta cells. However, there are multiple immunological challenges associated with this procedure, all of which must be adequately addressed prior to translation from trials in small animal and nonhuman primate models to human clinical trials. Principal threats to graft viability include immune-mediated destruction triggered by immunogenic alginate impurities, unfavorable polymer composition and surface characteristics, and release of membrane-permeable antigens, as well as damage associated molecular patterns (DAMPs) by the encapsulated islets themselves...

Complementary to traditional gene mapping approaches used to identify the hereditary components of complex diseases, integrative genomics and systems genetics have emerged as powerful strategies to decipher the key genetic drivers of molecular pathways that underlie disease. Broadly speaking, integrative genomics aims to link cellular-level traits (such as mRNA expression) to the genome to identify their genetic determinants. With the characterization of several cellular-level traits within the same system, the integrative genomics approach evolved into a more comprehensive study design, called systems genetics, which aims to unravel the complex biological networks and pathways involved in disease, and in turn map their genetic control points...

Mitochondria play a critical role in several cellular processes and cellular homeostasis. Mitochondrion dysfunction has been correlated with numerous metabolic diseases such as obesity and type 2 diabetes. MicroRNAs are non-coding RNAs that have emerged as key regulators of cell metabolism. The microRNAs act as central regulators of metabolic gene networks by leading to the degradation of their target messenger RNA or repression of protein translation. In addition, vesicular and non-vesicular circulating miRNAs exhibit a potential role as mediators of the cross-talk between the skeletal muscle and other tissues/organs...

Regulatory peptides produced in islet and gut endocrine cells, including glucagon, GLP-1, GLP-2, and GIP exert actions with considerable metabolic importance and translational relevance. Although the clinical development of GLP-1 receptor (GLP-1R) agonists and dipeptidyl peptidase-4(DPP4) inhibitors has fostered research into how these hormones act on the normal and diseased heart, less is known about the actions of these peptides on blood vessels. Here we review the effects of these peptide hormones on normal blood vessels, and highlight their vascular actions in the setting of experimental and clinical vascular injury...

The number of individuals with chronic cutaneous wounds has been increasing worldwide due to an aging population, diabetes, obesity, and cardiovascular disease. In the United States, almost seven million Americans have chronic skin ulcers. Many therapeutic approaches have been used. However, the treatment outcomes are not always ideal because of failure to achieve complete wound closure in around 60% of cases, scarring, and high rate of recurrence. Therefore, there is a need for more effective therapies. Stem cells offer promising possibilities...

Type 1 diabetes (T1D) is an autoimmune disease characterized by the selective destruction of the insulin-producing beta cells. Beta cell dysfunction caused by an inflammatory microenvironment is believed to trigger the peripheral activation of CD4 and CD8 autoreactive T cells. This review will compile post-transcriptional and post-translational modifications (PTM) involved in the generation of beta cell neoantigens and proposes a reconstruction of the sequence of events connecting environmental changes and autoimmunity...

The traditional medicine in Africa in general and specifically in Cameroon does not manage diabetes and arterial hypertension very well. Yet, these pathologies are becoming more prevalent among the populations that need adequate knowledge to fight against them. Therefore the present study was designed to determine the knowledge, attitudes and practices of indigenous people regarding diabetes and hypertension control, and to assess the epidemiological aspects of these diseases in order to reinforce their health education and promote a better health care through traditional medicine...

Information about normal hepatic glucose metabolism may help to understand pathogenic mechanisms underlying obesity and diabetes mellitus. In addition, liver glucose metabolism is involved in glycosylation reactions and connected with fatty acid metabolism. The liver receives dietary carbohydrates directly from the intestine via the portal vein. Glucokinase phosphorylates glucose to glucose 6-phosphate inside the hepatocyte, ensuring that an adequate flow of glucose enters the cell to be metabolized. Glucose 6-phosphate may proceed to several metabolic pathways...

Many promising findings from pre-clinical research have failed to translate to the clinic due to their inability to incorporate human disease co-morbidity. A variety of rodent diets and feeding durations are currently used in models of human metabolic syndrome, obesity and diabetes. One model, the Cafeteria (CAF) diet, makes use of grocery store-purchased food items that more closely approximate the human ultra-processed diet than commercial high-fat or high-sugar rodent diets. The present study describes the development of metabolic syndrome in rats fed a CAF diet as well as the recovery of metabolic syndrome following a healthy "lifestyle" change...
