Therapeutic potency of crocin in the treatment of inflammatory diseases: Current status and perspective

Crocin is the major component of saffron, which is used in phytomedicine for the treatment of several diseases including diabetes, fatty liver, depression, menstruation disorders, and, of special interest in this review, inflammatory diseases. Promising selective anti-inflammatory properties of this pharmacological active component have been observed in several studies. Saffron has been shown to exert anti-inflammatory properties against several inflammatory diseases and can be used as a novel therapeutic agent for the treatment of inflammatory diseases either alone or in combination with other standard anti-inflammatory agents. This review summarizes the protective role of saffron and its pharmacologically active constituents in the pathogenesis of inflammatory diseases including digestive diseases, dermatitis, asthma, atherosclerosis, and neurodegenerative diseases for a better understanding and hence a better management of these diseases.

Emerging role of HMGB1 in lung diseases: friend or foe

Lung diseases remain a serious problem for public health. The immune status of the body is considered to be the main influencing factor for the progression of lung diseases. HMGB1 (high‐mobility group box 1) emerges as an important molecule of the body immune network. Accumulating data have demonstrated that HMGB1 is crucially implicated in lung diseases and acts as independent biomarker and therapeutic target for related lung diseases. This review provides an overview of updated understanding of HMGB1 structure, release styles, receptors and function. Furthermore, we discuss the potential role of HMGB1 in a variety of lung diseases. Further exploration of molecular mechanisms underlying the function of HMGB1 in lung diseases will provide novel preventive and therapeutic strategies for lung diseases.     

Polyglutamine-mediated neurodegeneration: Use of chaperones as prevention strategy

Polyglutamine diseases are a class of inherited neurodegenerative disorders caused by the expansion of a polyglutamine tract within the respective proteins. Clinical studies have revealed that the forming of neuronal intranuclear inclusions by the disease protein is a common pathological feature of polyglutamine diseases. Although there has been considerable progress in understanding polyglutamine diseases, many questions regarding their mechanism are still unanswered. The finding that molecular chaperones are associated with ubiquitinated intranuclear inclusions clearly indicates a crucial role of molecular chaperones in the generation of these fatal diseases. Molecular and chemical chaperones have been found to be a good agent for suppressing many polyglutamine diseases in several animal models. In this review, I discuss the roles of the ubiquitin-proteasome pathway and molecular chaperones in the development of polyglutamine diseases and probable approach for the prevention of many of these fatal disorders using molecular chaperones as a therapeutic agent. Newly found chemical chaperones have been demonstrated to be potentially useful and could be used as a therapeutic strategy in preventing many versions of polyglutamine diseases.     

THERPA: A small molecule database related to prion protein regulation and prion diseases progression

Prion diseases are fatal neurodegenerative disorders that affect humans and animals. Although various small molecules have been evaluated for application in the treatment of prion diseases, none have been shown to be efficacious. Expanding our knowledge of these molecules is important for understanding of the complex mechanisms of prion diseases. To improve access to the scattered information on small molecules related to prion diseases, we built a database of therapeutic molecules associated with prion diseases (THERPA, therpa.pythonanywhere.com). THERPA includes 119 small molecules and their 283 relationships with prion diseases. THERPA is an interactive visual database and useful for improving search efficiency which can help researchers identify intrinsic small molecules that can be used for developing therapeutics for prion diseases.     

Disease-Aging Network Reveals Significant Roles of Aging Genes in Connecting Genetic Diseases

One of the challenging problems in biology and medicine is exploring the underlying mechanisms of genetic diseases. Recent studies suggest that the relationship between genetic diseases and the aging process is important in understanding the molecular mechanisms of complex diseases. Although some intricate associations have been investigated for a long time, the studies are still in their early stages. In this paper, we construct a human disease-aging network to study the relationship among aging genes and genetic disease genes. Specifically, we integrate human protein-protein interactions (PPIs), disease-gene associations, aging-gene associations, and physiological system–based genetic disease classification information in a single graph-theoretic framework and find that (1) human disease genes are much closer to aging genes than expected by chance; and (2) diseases can be categorized into two types according to their relationships with aging. Type I diseases have their genes significantly close to aging genes, while type II diseases do not. Furthermore, we examine the topological characters of the disease-aging network from a systems perspective. Theoretical results reveal that the genes of type I diseases are in a central position of a PPI network while type II are not; (3) more importantly, we define an asymmetric closeness based on the PPI network to describe relationships between diseases, and find that aging genes make a significant contribution to associations among diseases, especially among type I diseases. In conclusion, the network-based study provides not only evidence for the intricate relationship between the aging process and genetic diseases, but also biological implications for prying into the nature of human diseases.     

Medico-genetic study of the population of Uzbekistan. VI. Hereditary pathology among the populations of 4 regions of the Kashkadarinskaia area]

The screening for families burdened with multiple cases of non-infectious diseases, the diagnostic of those diseases and the investigation of relations between the population structure and the distribution of hereditary diseases in 4 districts of the Kashkadarja province were carried out. On the basis of the data obtained the load of excessive hereditary diseases was calculated and nosological spectrum was described; it included more than 30 different diseases. The study of spatial distribution of recessive diseases has shown that the load of hereditary diseases may be accounted for the positive assortative matings. The high level of interpopulation migration prevents from the local accumulation of a certain hereditary disease.     

Risk of neurological diseases among survivors of electric shocks: a nationwide cohort study, Denmark, 1968-2008

Several studies suggest a link between electric injuries and neurological diseases, where electric shocks may explain elevated risks for neuronal degeneration and, subsequently, neurological diseases. We conducted a retrospective cohort study on the risk of neurological diseases among people in Denmark who had survived an electric accident in 1968-2008. The cohort included 3,133 people and occurrences of neurological diseases were determined by linkage to the nationwide population-based Danish National Register of Patients. The numbers of cases observed at first hospital contact in the cohort were compared with the respective rates of first hospital contacts for neurological diseases in the general population. We observed significantly increased risks for peripheral nerve diseases (standardized hospitalization ratio (SHR), 1.66; 95% confidence interval (CI), 1.22-2.22), for migraine (SHR, 1.80; 95% CI, 1.23-2.54), for vertigo (SHR, 1.60; 95% CI, 1.22-2.05), and for epilepsy (SHR, 1.45; 95% CI, 1.11-1.85). Only small numbers of cases of other neurological diseases were found, making the risk estimates unstable. These findings suggest an association between a single electric shock and increased risks for peripheral nerve diseases, migraines, vertigo, and epilepsy, but confirmation of these observations is needed.

Searching for biomarkers: humoral response profiling with luciferase immunoprecipitation systems

B-cell-mediated humoral responses are triggered in many human diseases, including autoimmune diseases, cancer, and neurologic and infectious diseases. However, the full exploitation of the information contained within a patient’s antibody repertoire for diagnosis, monitoring and even disease prediction has been limited due to the poor diagnostic performance of many immunoassay formats. We have developed luciferase immunoprecipitation systems (LIPS) that harnesses light-emitting proteins to generate high-definition antibody profiles that are optimal for both diagnostics and biomarker discovery. Here, we describe the results and implications from a range of LIPS-antibody profiling studies performed in our laboratory. These include highly sensitive diagnostics for domestic and global pathogens, insights into infection-related diseases, discovery of new biomarkers for human diseases, subcategorization of symptoms and identification of pathogenic autoantibodies against self-proteins. These investigations highlight the types of humoral response profiles associated with different diseases, provide new information related to disease pathogenesis and offer a framework for incorporating LIPS antibody profiling into global health initiatives and disease monitoring.     

Role of complement in glomerular diseases

The complement system, composed of nearly 30 proteins, is a key regulator of immunity. The complement system is critical for protecting hosts from invading pathogens. Dysregulation of this system is associated with susceptibility to infection and various autoimmune diseases. Furthermore, complement activation due to the defective regulation of the alternative pathway will induce glomerular diseases. Anti-complement therapy has been applied in various glomerular diseases. Signaling pathways might be very important in the pathogenesis of glomerular diseases. This review will give a relatively complete signaling pathway flowchart for complement and a comprehensive understanding of the underlying role of complement in glomerular diseases.     

Modern probabilistic and statistical approaches to search for nucleotide sequence options associated with integrated diseases

Complex diseases are a major important problem for modern medicine. These diseases arise under the influence of specific environmental and clinical-demographic factors, so-called risk factors, in combination with factors of genetic heredity. The contribution of genetic factors to the development of complex diseases is on average about 50%. The cause of complex diseases can be a lot of variants of the nucleotide sequence. In addition to common variants of single nucleotide polymorphisms (SNPs), rare variants also play a role in the development of complex diseases. This review presents modern probabilistic and statistical approaches to the search for gene variants and their combinations associated with complex diseases with an emphasis on methods for finding rare and unique variants. A comparative analysis of these approaches is performed, and a number of problems requiring resolution are formulated.     

Molecular aspects of disease pathogenesis in the transmissible spongiform encephalopathies

The transmissible spongiform encephalopathies (TSE), or prion diseases, are a group of rare, fatal, and transmissible neurodegenerative diseases of mammals for which there are no known viral or bacterial etiological agents. The bovine form of these diseases, bovine spongiform encephalopathy (BSE), has crossed over into humans to cause variant Creutzfeldt-Jakob disease. As a result, BSE and the TSE diseases are now considered a significant threat to human health. Understanding the basic mechanisms of TSE pathogenesis is essential for the development of effective TSE diagnostic tests and anti-TSE therapeutic regimens. This review provides an overview of the molecular mechanisms that underlie this enigmatic group of diseases.     

Emerging Infectious Diseases in Free-Ranging Wildlife–Australian Zoo Based Wildlife Hospitals Contribute to National Surveillance

Emerging infectious diseases are increasingly originating from wildlife. Many of these diseases have significant impacts on human health, domestic animal health, and biodiversity. Surveillance is the key to early detection of emerging diseases. A zoo based wildlife disease surveillance program developed in Australia incorporates disease information from free-ranging wildlife into the existing national wildlife health information system. This program uses a collaborative approach and provides a strong model for a disease surveillance program for free-ranging wildlife that enhances the national capacity for early detection of emerging diseases.     

Genetics of common disease: implications for therapy,screening and redefinition of disease.

Susceptibility to most common human diseases is, at least in part, determined by genetic factors. Rapid progress is being made in defining these genetic determinants for a range of diseases including breast cancer, colon cancer, diabetes, arthritis and dementia. The ability to define susceptibility in genetic terms has already led to a reclassification of some of these diseases on genetic and mechanistic grounds. This information is likely to have a profound effect on our approach to human diseases as it will allow a better definition of these disorders, permitting more effective therapeutic intervention, and will lead to both a more precise understanding of the natural history of these diseases and the possibility of identifying populations at risk. An understanding of the mechanisms underlying disease susceptibilty will also improve our ability to develop rational therapeutic interventions for many of these diseases. The role of genetic screening in these common diseases will be discussed, particularly in regard to the application of health care in populations.     

Understanding hereditary diseases using the dog and human as companion model systems

Animal models are requisite for genetic dissection of, and improved treatment regimens for, human hereditary diseases. While several animals have been used in academic and industrial research, the primary model for dissection of hereditary diseases has been the many strains of the laboratory mouse. However, given its greater (than the mouse) genetic similarity to the human, high number of naturally occurring hereditary diseases, unique population structure, and the availability of the complete genome sequence, the purebred dog has emerged as a powerful model for study of diseases. The major advantage the dog provides is that it is afflicted with approximately 450 hereditary diseases, about half of which have remarkable clinical similarities to corresponding diseases of the human. In addition, humankind has a strong desire to cure diseases of the dog so these two facts make the dog an ideal clinical and genetic model. This review highlights several of these shared hereditary diseases. Specifically, the canine models discussed herein have played important roles in identification of causative genes and/or have been utilized in novel therapeutic approaches of interest to the dog and human.     

Regional variations and trends in mortality from cardiovascular diseases in population aged 0-64 in Dalmatia and Slavonia, 1998-2009

The aim of this paper was to analyse the regional variations and trends in mortality from cardiovascular diseases in the population aged 0-64 years in Dalmatia and Slavonia, over the period 1998 to 2009. Mortality data were derived from Central Bureau of Statistics. The results show that age-standardized mortality rates from total cardiovascular diseases, ischaemic heart diseases and cerebrovascular diseases were lower in Dalmatia than rates for Slavonia, for both genders. All mortality rates, except rates for ischaemic heart diseases mortality for men in both regions, showed the trend of decline. Dalmatia has a more protective factors in pattern of Mediterranean diet. The improvement of cardiovascular health and reduction of premature mortality from cardiovascular diseases requires a system and comprehensive intervention approach at all levels of health care and multisectorial coordination.
