For hospitalized patients, and especially patients in intensive care unit s, these bacterial infections pose a serious and as of 2010 rapidly emerging threat. cquote Overuse of antimicrobial agents and problems with infection control practices have led to the development of multidrug resistant gram negative bacterial infections. We used to use carbapenems as the main option in several countries for those severe infections however, now there are several mechanisms of resistance, including carbapenemase production among Acinetobacter , Pseudomonas , and Klebsiella isolates. Subsequently, carbapenems are sometimes not active against those serious infections. That is why clinicians around the world have reconsidered the use of older antimicrobial agents, including polymyxins . Matthew Falagas, MD. The above quote was taken from an interview by Luke F.

  1. Resistance (military)

    Unreferenced date February 2007 In military terminology, resistance or organised resistance refers to the ability of a military unit to continue to oppose an attack. Resistance ends when a unit surrender military surrender s, when all members of unit are killed or captured, or when a unit disperses. The term is used in the phrase organized resistance has ceased to describe the end of a battle or military campaign campaign when no formal surrender occurs after a unit is defeated. The term also occurs in the phrase Salients, re entrants and pockets pocket of resistance .

  1. Horizontal resistance

    In genetics , the term horizontal resistance was first used by J.E. Vanderplank ref name Vanderplank1963 Vanderplank, J.E. 1963 Plant Diseases Epidemics and Control. Academic Press, New York and London, 349pp. ref to describe many gene resistance. This contrasts with the term Vertical Resistance vertical resistance which was used to describe single gene resistance. Raoul A Robinson Raoul A. Robinson ref name Robinson1976 Raoul A Robinson Robinson, Raoul A. 1976 Plant Pathosystems. Springer Verlag, Berlin, Heidelberg, New York, 184pp. ref further refined the definition of horizontal resistance. Unlike Vertical Resistance vertical resistance and parasitic ability, horizontal resistance and horizontal parasitic ability are entirely independent of each other in genetic terms. In the first round of breeding for horizontal resistance, plants are exposed to pathogens and selected for partial resistance. Plants unaffected by the pathogen have vertical resistance and are removed. Obviously plants with no resistance die, the remaining plants have partial resistance and their seed is stored and bred back up to sufficient volume for further testing. The hope is that in these remaining plants are multiple types of partially resistant genes, and by crossbreeding this pool back on itself multiple partial resistance genes will be encouraged and provide resistance to a larger variety of pathogens than vertical resistance . Successive rounds of breeding for horizontal resistance proceed in a more traditional fashion, selecting plants for disease resistance as measured by yield. These plants are exposed to native regional pathogens, and given minimal assistance in fighting them. ref name Beyond GMO the REAL answer to healthy, disease resistant crops http newfarm.rodaleinstitute.org international pan am don nov04 chapingo.shtml ref References reflist 2 Category Phytopathology Category Molecular biology genetics stub ...   more details

  1. Resistance training

A broader meaning that refers to any training that uses a resistance to the force of muscular contraction better termed strength training , and elastic or hydraulic resistance, which refers to a specific type of strength training that uses elastic or hydraulic tension physics tension to provide this resistance.

  1. Cross-resistance

    Cross resistance is the Drug tolerance tolerance to a usually toxic substance as a result of exposure to a similarly acting substance. It is a phenomenon affecting e.g. pesticide s and antibiotic s. As an example rifabutin and rifampin cross react in the treatment of tuberculosis.

  1. Radiation resistance

    Radiation resistance is that part of an antenna electronics antenna s feedpoint resistance that is caused by the radiation of Electromagnetic radiation electromagnetic waves from the antenna. The radiation resistance is determined by the geometry of the antenna, not by the materials of which it is made. It can be viewed as the equivalent resistance to a resistor in the same circuit. Radiation resistance is caused by the radiation reaction of the conduction electrons in the antenna electronics antenna . When electrons are accelerated, as occurs when an AC electrical field is impressed on an antenna electronics antenna , they will radiate electromagnetic waves. These waves carry energy that is taken from the electrons. The loss of energy of the electrons appears as an effective resistance to the movement of the electrons, analogous to the ohmic resistance caused by scattering of the electrons in the crystal lattice of the metallic conductor. While the energy lost by ohmic resistance is converted to heat, the energy lost by radiation resistance is converted to electromagnetic radiation. Power physics Power is calculated as math P I 2R , math where math I math is the electric current flowing into the feeds of the antenna electronics antenna and math P math is the power in the resulting electromagnetic field. The result is a virtual, effective Electrical resistance resistance math R frac P I 2 , math This effective resistance is called the radiation resistance. Thus the radiation resistance of an antenna is a good indicator of the strength of the electromagnetic field radiated by a transmitting antenna or being received by a receiving antenna, since its value is directly proportional to the power of the field.
