The intentional release of biological agents by belligerents or terrorists is a possibility that has recently attracted increased attention. Law enforcement agencies, military planners, public health officials, and clinicians are gaining an increasing awareness of this potential threat. From a military perspective, an important component of the protective pre-exposure armamentarium against this...
SEPTEMBER/OCTOBER 2010 30 INTRODUCTION Certain workers, particularly in agriculture, are exposed to large quantities of dust during their work. The dust consists of varying amounts of inorganic material, organic substances of plant and animal origin as well as viable and non-viable microorganisms and their by-products (biochemical components, toxins, antigens).1-4 The pathogenic role of dust co...
Cytokines and Rheumatoid Arthritis The term “cytokine” is coined from the combination of “cyto”, a prefix which means cell, and “kine”, which denotes movement. Cytokines all have the following features: 1. They are low-molecular-weight glycoproteins that are not hormones. 2. They have an effect at very small concentrations. 3. Different cytokines can have the same function (redundancy). For exa...
Quantum mechanical models have been proposed for biological processes and for cognition and decision in domains that appear to be beyond the de Broglie wavelength. The basis of such quantum behavior is seen variously as quantum fields and virtual and entangled particles, and the determination that the behavior is quantum is made on coherence, order and interference effects, and non‐local behavi...
s. Further, the number of possible references has become so large that reviews are sometimes included; if they contain category A references, they will be referred to as category A
Inflammatory uveitis is a difficult condition to treat. Recently, a new class of drugs obtained by a biological process and therefore defined as “biologics” has been successfully used in the treatment of immunemediated rheumatic diseases. These drugs target different pro-inflammatory cytokines including tumor necrosis factor-α, interleukin-1 and interleukin-6, or immune effector cells including...
Biological agents represent an important addition to the therapies for immuno-inflammatory conditions and have a great impact on the disease course and quality of life of these patients. However, recent reports of serious infections like tuberculosis, demyelinating and neurodegenerative diseases, pancytopenia, cardiovascular diseases, etc. after anti-TNF therapy raised questions on their safety...
Biological agents targeting inflammatory skin diseases have dramatically overcome many of the limitations older oral therapeutic options. Among various biological agents, ixekizumab is a humanised monoclonal antibody that blocks activity IL-17A, which exhibited high efficacy against psoriasis. Although there are limited number cutaneous adverse reactions, biologic-induced type I allergic reacti...
We define a bioinformant as a software agent with specific abilities to serve as an assistant for a biologist. This paper describes the design guidelines and the first implementation of BIOINFORMANTS: a platform for scientific computing on the web. The goal of this project is to develop a computational, web-oriented, software platform to recover and analyze genetic information, (re)using existi...
What is a strategy? The term strategy has been used by many disciplines in a variety of contexts ranging, for example, from the game of chess and the Cuban missile crisis to markets, computer networks, political systems, cooperation, mating, parasitism, intragenomic conflict, and growth patterns. Despite this wide use of the term, only one discipline—game theory— has carefully examined the conc...
