A Perspective on Remanufacturing Business: Issues and Opportunities
The purpose of this section, then, is to dissect the business of remanufacturing in order to highlight their strengths and weaknesses, its opportunities and its dangers. In the forth section we sum up some results of this study and future possible developments
NF-κB pathway activators as potential ageing biomarkers: targets for new therapeutic strategies.
Chronic inflammation is a major biological mechanism underpinning biological ageing process and age-related
diseases. Inflammation is also the key response of host defense against pathogens and tissue injury. Current opinion
sustains that during evolution the host defense and ageing process have become linked together. Thus, the large
array of defense factors and mechanisms linked to the NF-κB system seem to be involved in ageing process. This
concept leads us in proposing inductors of NF-κB signaling pathway as potential ageing biomarkers. On the other
hand, ageing biomarkers, represented by biological indicators and selected through apposite criteria, should help to
characterize biological age and, since age is a major risk factor in many degenerative diseases, could be
subsequently used to identify individuals at high risk of developing age-associated diseases or disabilities. In this
report, some inflammatory biomarkers will be discussed for a better understanding of the concept of biological
ageing, providing ideas on eventual working hypothesis about potential targets for the development of new
therapeutic strategies and improving, as consequence, the quality of life of elderly populatio
Peripheral Biomarkers in Manifest and Premanifest Huntington’s Disease
Huntington's disease (HD) is characterized by clinical motor impairment (e.g., involuntary movements, poor coordination, parkinsonism), cognitive deficits, and psychiatric symptoms. An inhered expansion of the CAG triplet in the huntingtin gene causing a pathogenic gain-of-function of the mutant huntingtin (mHTT) protein has been identified. In this review, we focus on known biomarkers (e.g., mHTT, neurofilament light chains) and on new biofluid biomarkers that can be quantified in plasma or peripheral blood mononuclear cells from mHTT carriers. Circulating biomarkers may fill current unmet needs in HD management: better stratification of patients amenable to etiologic treatment; the initiation of preventive treatment in premanifest HD; and the identification of peripheral pathogenic central nervous system cascades
Gender-Related Immune-Inflammatory Factors, Age-Related Diseases, and Longevity
This review discusses the role of estrogens as pro- or antiinflammatory players in immune-inflammatory responses.
In particular, their role in Alzheimer’s disease (AD), an example of immune-inflammatory disease, is
discussed briefly. AD is a progressive neurodegenerative disease, which in Western societies accounts for the
majority of cases of clinical senile dementia. However, sexual dimorphism of diseases may also depend on
factors independent of sex hormones (i.e., a gender effect), as demonstrated by our data on differential longevity
in females and males. In fact, differences in mortality between men and women are not only a question of sex
that refers to biological differences, but rather a question of ‘‘socially constructed sex,’’ a question of gender
(i.e., the characteristics that a society or culture delineates as masculine or feminine). In gender medicine, we
conclude that it is important to consider the role played both by hormones, customs, and educational levels
regarding the different propensity of males and females to fall ill. So, in programming antiaging strategies, we
have also to take these aspects into accoun
CADASIL or MS? Consider “Red Flags” but Avoid a Misdiagnosis: Case Series of a Concomitant Diagnosis
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a monogenic autosome-dominant disease with chronic clinical course. Rarely, CADASIL may present with atypical relapsing-remitting manifestations, cerebral and spinal white matter lesions, mimicking inflammatory CNS disease as multiple sclerosis (MS). The rarely co-occurrence of MS and CADASIL may represent a hard challenging diagnosis even for an expert neurologist. Here, we present a case series of two patients with CADASIL showing MRI pattern overlapping MS. They were the only case of co-occurrence of CADASIL and MS in their own family. Both patients were treated with anti-inflammatory and anti-platelet drugs, mostly with good response. Pathogenic hypothesis highlights that genetic events, related to monogenic disease, may expose CNS antigens with a consequent self-immune attack. In CADASIL, the function of Notch3 receptor showed a consistent interplay with immune system activity. Indeed, certain mutations of Notch3 receptor show abnormal upregulation of specific pro-inflammatory patterns. However, even if it is not possible to determinate if the proinflammatory activity may be promoted by pathogenic mutations in Notch3, the "apparent" difference between MS and “inflammatory CADASIL” could be considered more semantic than etiologic
Swimming at the time of covid-19. A cross-sectional study among young italian competitive athletes
During the coronavirus disease 2019 (COVID-19) pandemic, several restriction measures were imposed to control the virus transmission, with important repercussions on different sectors, including sport. This study aimed to explore the effects of the COVID-19 pandemic on Italian competitive swimmers by analyzing how the disease and the restriction measures affected their training. In total, 396 competitive swimmers (mean age 16.0 ± 3.2 years) participated. A questionnaire was used to collect their general information, to assess whether they had had COVID-19 and the number of training days lost due to the disease or to the closure of swimming facilities, and the possible alternative training adopted. Twenty-four (6.1%) participants had had COVID-19 and lost, on average, 32 training days. The closure of facilities caused an interruption in swimming training for about 18% of the participants. The majority of these continued their training, mainly through home-based exercise, but reduced their weekly training time (-8 median hours/week). A positive association was found between regularly adopted weekly training volume and that assumed during pandemic closure (OR 9.433, CI95% 1.644-54.137, p = 0.012), suggesting that the previous level of engagement in sport can represent a predictor of exercise maintenance in challenging situations such as a pandemic. Further studies are needed to identify personal, environmental, and social resources that can help individuals to counteract the negative effects of restriction measures
The Role of Target Therapy in the Treatment of Gastrointestinal Noncolorectal Cancers: Clinical Impact and Cost Consideration
Gastrointestinal (GI) tumors are among the leading cause of death in cancer patients worldwide. Particularly, gastric cancer (GC) is the third cause of cancer deaths, whereas esophageal neoplasm is the eighth leading most common cancer worldwide and its incidence, especially adenocarcinoma type, is continuously increasing. Also, Hepatocellular carcinoma, Cholangiocarcinoma and pancreatic cancer represent a very interesting model to multidisciplinary approach and recently new drugs are used in their treatment. Currently, new clinical trials are designed including classic chemotherapy in association with either small molecule inhibitors (i.e. Tyrosine Kinase inhibitors) and/or monoclonal antibody (i.e. anti-EGFR antibody). Moreover, a comprehensive list of new molecules for target therapy is included in this issue. The development of new treatment modalities (multidisciplinary approach) and targeted therapy approaches have contributed to improving the outcome in these cancer diseases. During the past few years, remarkable progress in molecular biology of malignancy, the discovery of specific targets, and the resulting development of systemic drugs that block critical kinases and several molecular pathways have all contributed to progress in cancer treatment, also in GI non-colorectal cancer treatment
