| Acute and chronic progression of injury to the kidney leads to the failure of the renal system and has become an increasingly important cause of morbidity and mortality. Present diagnosis detects the condition only after irreversible loss of 70 percent of kidney function. Current research is focused only on the clinical manifestations after the kidney injuries and not towards the exact cause of the condition. Here we propose a new outlook- that there is an involvement of a pathogen in the pathogenesis of kidney injuries. Basis for our proposal is given by the similarity of the pathogenesis events occurring between a classical example of hepatitis and kidney injuries. Furthermore, literature regarding the role of early kidney injury biomarkers in innate... |

| Women who inherit a defective BRCA1 or BRCA2 gene have risks for breast and ovarian cancer that are so high and seem so selective that many mutation carriers choose to have prophylactic surgery. There has been much conjecture to explain such apparently striking tissue specificity. All these suggestions share the assumption that some disabled function of normal tumor suppressor genes leads to a tissue specific cancer response. Here the idea is proposed and tested that major determinants of where BRCA1/2 hereditary cancers occur are related to tissue specificity of the cancer pathogen, the agent that causes chronic inflammation or the carcinogen. The target tissue may have receptors for the pathogen, become selectively exposed to an inflammatory process... |

| The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology and the Tree of Life (TOL) is a major paradox in biology. This article presents a broad, unifying scenario on the origin and evolution of cellular and viral domains that challenges the conventional views about the history of life and supports a TOL that includes viruses. Co-evolution of viruses and their host cells has led to some of the most remarkable developments and transitions in the evolution of life, including the origin of non-coding DNA as a genomic protective device against viral insertion damage. However, one of the major fundamental evolutionary... |

| ABSTRACT The effect of the ethanolic extract of propolis (EEP) on Aeromonas hydrophila was analyzed by determination of minimum inhibitory concentration (MIC). Then, the effects of crude propolis powder (CPP) on growth, hemato-immune parameters of the Nile tilapia, as well as its effects on resistance to A. hydrophila challenge were investigated. The CPP (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0%) was added to the diet of 280 Nile tilapia (50.0 ± 5.7 g fish-1). Hemato-immune parameters were analyzed before and after the bacterial challenge. Red blood cell, hematocrit, hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), and hydrogen peroxide (H2O2) and nitric oxide (NO) were evaluated. The MIC of the EEP was 13% (v/v) with a... |

| Alzheimer's disease is a common neurodegenerative disorder. However, its exact etiology is still unknown. There were several mechanisms proposed such as the tau hypothesis and amyloid hypothesis. However, there is evidence challenging the above two hypotheses. Here, I propose the immune-amyloid hypothesis as a mechanism for Alzheimer's disease. Th17 related autoimmunity contributes to the disease pathogenesis. Accumulation of misfolded beta amyloid can trigger heat shock protein which in turn induces TH17 immunity. By microarray analysis of peripheral blood mononuclear cells, there is up-regulation of many TH17 related molecules after Alzheimer's disease. After knowing the exact disease pathogenesis, we can develop new... |

| Models of epidemics allow decision makers to explore the consequences of different interventions. The Models of Infectious Disease Agent Study (MIDAS) project has been collecting studies, models, data supporting the models, and publications providing historical evidence about epidemics.
An ontology has been developed for MIDAS to support the collection, documentation, and dissemination of models. It uses relations to link taxonomies (including a subset of the infectious disease ontology) that define the scope of its models and supporting documentation.
The ontology is used to aid in the navigation process that is part of the user interface for identifying which studies and publications are available in the MIDAS repository... |

| Angiogenesis is a crucial component of lung pathophysiology, not only in cancer but also in other disorders, such as chronic obstructive pulmonary disease (COPD). In COPD angiogenesis is definitely able to control and orchestrate the progression of airway remodeling. Herein, we provide several remarkable translational aspects of angiogenesis in COPD, exploring both basic and clinical research in this field. Indeed, we present a number of pro- and anti-angiogenic factors, which can be also used as potential biomarkers to monitor disease progression.

| Antibody targeting of cancer is showing clinical and commercial success after deep research and development over the last 3 decades. They have the great potential to deliver long-term cures but a shift in thinking towards a cancer stem cell (CSC) model for tumour development is certain to have an impact on how antibodies are selected and developed, the targets they bind to and the drugs used in combination with them. CSCs have been identified from many human tumours and share many of the characteristics of normal stem cells such as the ability to renew and metabolically or physically protect themselves from xenobiotic and DNA damage. Targeting CSCs could be a strategy to improve the outcome of cancer therapy. Monoclonal antibodies are clinically and... |

| Cryptosporidium parvum is a zoonotic apicomplexa-protozoan pathogen that causes gastroenteritis and diarrhoea in mammals worldwide. The organism is transmitted by ingestion of oocysts, which are shed in faeces, and completes its lifecycle in a single host.^1^ C. parvum is ubiquitous on dairy operations worldwide and is one of the leading causes of diarrhoea in calves on these farms.^2,3^ Here, for the first time, we describe the antibody response in a large group of cows to a recombinant C. parvum oocyst surface protein (rCP15/60) vaccine and the antibody response in calves fed rCP15/60-immune colostrum produced by these vaccinated cows. Results of recent genotype surveys indicate that calves are the only major reservoir for C. parvum infections in... |

| Human immunodeficiency virus (HIV), with about 30 million deaths and double infections (in developing countries), is an open challenge today for global scientists. Developing safe and effective measurements against it has become the prime need of hour. Though, putting it at health priority, various efforts like chemotherapy, vaccines and others are attempted globally over last decade. Consequently, highly active antiretroviral therapy was introduced but fails to completely block the viral replication due to drug resistance and various other severe side effects. The antigenic variability and lack of appropriate experimental models is the major obstacle in the development of an ever effective treatment against HIV. However, to overcome the present hurdles... |

| The US CDC believes that 65% of all infections in developed countries may be caused by pathogens in biofilms. Electron Microscopy has shown that these bacterial communities can evade phagocytosis, and persist in the cytoplasm of monocytes, macrophages, lymphocytes and neutrophils. Three decades ago, Wirostko _et al._ found such intraphagocytic communities in Crohn’s disease, Juvenile Rheumatoid Arthritis and Sarcoidosis. However, the mechanism(s) by which such persistent bacteria could evade the immune system have remained elusive. Recently, 16S RNA from species of gliding bacteria never thought to be able to survive _in vivo_, have been found in surgically removed biofilms. This study set out to identify whether the genomes of these gliding... |
