Recent experimental studies demonstrate that medications targeting aging (antioxidants, calorie restriction mimetics, autophagy inductors, etc.) can substantially promote health and extend lifespan. Pharmacologically targeting aging appears to be more effective in preventing age-related pathology compared with treatments targeted to particular pathologies. The development of new antiaging drugs represents a great opportunity for the pharmaceutical and healthcare industries. © 2016 Elsevier Ltd.

Mediators of Inflammation | Year: 2015

Brain tissue is particularly susceptible to oxidative stress (OS). Increased production of reactive oxygen species (ROS), reduced antioxidant systems, and decreased efficiency in repairing mechanisms have been linked to Alzheimer's disease (AD). Postmortem studies in AD patients' brains have shown oxidative damage markers (i.e., lipid peroxidation, protein oxidative damage, and glycoxidation). Fermented papaya (FPP, a product of Carica papaya Linn fermentation with yeast) is a nutraceutical supplement with favorable effects on immunological, hematological, inflammatory, and OS parameters in chronic/degenerative diseases. We studied 40 patients (age 78.2 ± 1.1 years), 28 AD patients, and 12 controls. Urinary 8-OHdG was measured to assess OS. Twenty AD patients were supplemented with FPP (Immunage, 4.5 grams/day) for 6 months, while controls did not receive any treatment. At baseline, 8-OHdG was significantly higher in patients with AD versus controls (13.7 ± 1.61 ng/mL versus 1.6 ± 0.12 ng/mL, P<0.01). In AD patients FPP significantly decreased 8-OHdG (14.1 ± 1.7 ng/mL to 8.45 ± 1.1 ng/mL, P<0.01), with no significant changes in controls. AD is associated with increased OS, and FPP may be helpful to counteract excessive ROS in AD patients. © 2015 Mario Barbagallo et al.

The aim of this study is to gain further insights into the possible nutraceutical effect on redox balance via thioredoxin (Trx) modulation and on the intrinsic susceptibility of monocytes to generate an inflammatory response. The study group consisted of thirty-two patients with compensated Child A-C, HCV-related cirrhosis. The patients were supplemented for 6 months with 6g/day of a certified fermented papaya preparation (FPP). Fifteen unsupplemented, age/gender-matched healthy subjects served as controls. The patients filled in a detailed diet-life style questionnaire, and blood samples were collected to test routine biochemistry, Trx, redox status (GSH, GSSG, GSH/GSSG ratio, 4-HNE and α-tocopherol). Moreover, isolated monocytes were tested for ex-vivo LPS-stimulated TNFα production and TNFα mRNA. As compared to control, patients with liver cirrhosis showed a significantly higher serum level of Trx. A significant correlation occurred with GSH/GSSG ratio in Child B and C patients. FPP supplementation brought about a significant reduction of Trx with levels comparable to the ones of healthy controls. Ten patients Child C (31.2%) showed borderline low levels of α-tocopherol while all cirrhotic patients, as a whole, showed a significantly abnormal redox balance. Supplementation with FPP did not modify α-tocopherol depletion but significantly improved redox balance parameters. Patients with liver cirrhosis showed a significantly upregulated TNF-α production in a time-dependent manner and this effect was more pronounced in more advanced stages of the disease and showed a significant correlation with α-tocopherol level. Supplementation with FPP significantly, although partially, downregulated TNF-α production from monocytes. Taken altogether, it would appear that the typical oxidative-inflammatory biochemical milieu of these patients is mirrored by a significant TNF-α upregulation at a monocyte level while a targeted nutraceutical might be a potentially amenable intervention to be part of validated scheduled treatments.

Uncontrolled continued exposure to oxidative stress is a precursor to many chronic diseases including cancer, diabetes, degenerative disorders and cardiovascular diseases. Of the many known mediators of oxidative stress, reactive oxygen species (ROS) and advanced glycation end products (AGEs) are the most studied. In the present review, we have summarized current data on the origin of circulating AGEs, discussed issues associated with reliable assessment of its steady state level, and changes in its level with age and select metabolic diseases. Lastly, we have made recommendations about life style changes that may decrease AGEs burden to promote healthy aging.

The rates of child and adult obesity have increased in most developed countries over the past several decades. The health consequences of obesity affect both physical and mental health, and the excess body weight can be linked to an elevated risk for developing type 2 diabetes, cardiovascular problems, and depression. Among the factors that can influence the development of obesity are higher infant weights and increased weight gain, which are associated with higher risk for excess body weight later in life. In turn, mother's excess body weight during and after pregnancy can be linked to the risk for offspring overweight and obesity through dietary habits, mode of delivery and feeding, breast milk composition, and through the influence on infant gut microbiota. This review considers current knowledge of these potential mechanisms that threaten to create an intergenerational cycle of obesity. © 2014 Elsevier Inc.

Irritable bowel syndrome (IBS) is a high prevalence disease, whose symptoms are reported by a large number of young adults with significant effects on quality of life and social costs. Traditionally, IBS has been treated with dietary and lifestyle modification, fiber supplementation, psychological and pharmacological therapy. Since its complex and multifactorial etiopathogenesis is only partially known, therapeutic choices may be difficult and not always effective. New research efforts focused on the role of relationship between central nervous system and gut disorders (brain-gut axis), altered composition of gut microbiota (e.g. an eight times increased risk for IBS after Salmonella infection), immune activation with an increased number of T lymphocytes and mast cells associated with mucosa as well as an increased level of pro-inflammatory cytokines (IL-10 and IL-12, suggesting Th1 polarization), visceral hypersensitivity causing perception of pain even for minimal abdominal distension. Based on these findings, new possibilities of treatment are emerging with encouraging outcomes. Attention is directed to drugs that showed good tolerability profile and poor systemic absorption, which may make them suitable for repeated or long term treatments, as frequently required in patients with IBS. They have been successfully used drugs such as tachykinin receptors antagonists, tryptophan hydroxylase inhibitors, bile acid sequestrants, μ agonist and δ antagonist opioid receptors. Recent studies are discussed in this review, focusing both on new therapeutic approaches and innovative adaptation of previously available treatments.

Background: The prognosis and clinical management of patients with chronic liver diseases are closely related to the severity of liver fibrosis. Liver biopsy is considered the gold standard for the staging of liver fibrosis. However, it is an invasive test sometimes related to complications. This study aimed to assess the diagnostic value of enhanced liver fibrosis (ELF) test to predict liver fibrosis in patients with chronic hepatitis C. Methods: This study included 162 patients with liver disease and 67 healthy controls. Hyaluronic acid, tissue inhibitor of matrix metalloproteinase type 1, and amino-terminal propeptide type III procollagen were measured by enzyme-linked immunosorbent assay with the ELF test ADVIA Centaur ® (Siemens Healthcare Diagnostics Inc.). Fibrosis stage was determined using the Metavir scoring system. Results: In our study, for the diagnosis of significant fibrosis (Metavir F≥2) a cut-off value >7.72 provides a sensitivity of 93.0% and a specificity of 83.0%. The areas under the receiver operator characteristic curve, sensitivity, specificity, and positive and negative predictive values were 0.94, 93.3%, 81.0%, 93.3%, and 81.0%, respectively (P<0.001). For the diagnosis of cirrhosis (Metavir F=4) a cut-off value >9.3 provides a sensitivity of 93.0% and a specificity of 86.0%. The areas under the receiver operator characteristic curve, sensitivity, specificity, and positive and negative predictive values were 0.94, 79.1%, 90.8%, 75.6%, and 92.3%, respectively (P<0.001). Conclusions: The ELF test is a promising non-invasive method for assessing liver fibrosis in patients with chronic hepatitis C. It is effective in the diagnosis of both fibrosis and cirrhosis. © 2013, Hepatobiliary Pancreat Dis Int. All rights reserved.

Vaginal atrophy occurring during menopause is closely related to the dramatic decrease in ovarian estrogens due to the loss of follicular activity. Particularly, significant changes occur in the structure of the vaginal mucosa, with consequent impairment of many physiological functions. In this study, carried out on bioptic vaginal mucosa samples from postmenopausal, nonestrogenized women, we present microscopic and ultrastructural modifications of vaginal mucosa following fractional carbon dioxide (CO2) laser treatment. We observed the restoration of the vaginal thick squamous stratified epithelium with a significant storage of glycogen in the epithelial cells and a high degree of glycogen-rich shedding cells at the epithelial surface. Moreover, in the connective tissue constituting the lamina propria, active fibroblasts synthesized new components of the extracellular matrix including collagen and ground substance (extrafibrillar matrix) molecules. Differently from atrophic mucosa, newly-formed papillae of connective tissue indented in the epithelium and typical blood capillaries penetrating inside the papillae, were also observed. Our morphological findings support the effectiveness of fractional CO2 laser application for the restoration of vaginal mucosa structure and related physiological trophism. These findings clearly coupled with striking clinical relief from symptoms suffered by the patients before treatment. © 2014, Springer-Verlag London.

The QUEC PHISIS™ technology, based on the theory of coherence domains of water, is the most advanced application of quantum electrodynamics coherence suitable for transferring highly targeted and personalized electromagnetic signals to the living cells. Several experimental studies in aged rats confirm its beneficial action on vital cellular parameters while also optimizing the bioavailability and absorption of fundamental elements in cellular metabolism. Clinical observations have followed and have strengthened its applicability in healthy volunteers and in patients with complex diseases such as cardiovascular, neuromuscular, and metabolic disorders. Our pilot study on severely compromised, frail subjects corroborates its relevance. The delivery of correct frequencies has the potential to become a safe, very affordable, and effective therapeutic modality that is amenable to being integrated with pharmacological drugs, thus representing a substantial innovation in medical practice. © Copyright 2014, Mary Ann Liebert, Inc. 2014.

Diabetes mellitus and prostate cancer are 2 of the most important public health concerns, especially in the elderly population. Although diabetes has been recognized as a potent risk factor for many types of cancers, there is a large amount of evidence that shows that it has a protective role against prostate cancer. The underlying cause of this protective role is not fully understood, however, some mechanisms have been proposed in this area. In the present study we have reviewed these mechanisms and some new mechanisms are also proposed. © 2014 Elsevier Inc. All rights reserved.
