Tuberculosis is world-wide spread infectious disease with persistant high incidence, mainly in the densely populated countries with low income. Czech Republic belongs to the countries with highly efficient control of tuberculosis and continuously decreasing incidence of the disease. High-risk population for tuberculosis in the Czech Republic are the homeless people, who together with migrants from the countries with high incidence of tuberculosis represent reservoir of infection for our population. Treatment of tuberculosis is long-term, combined and controlled...

After the demonstration of its life-saving effect in severe hyperkalemia and the recovery of skeletal muscle after injury, pentadecapeptide BPC 157 has been shown to attenuate the local paralytic effect induced by succinylcholine, in addition to systemic muscle disability (and consequent muscle damage). Hyperkalemia, arrhythmias and a rise in serum enzyme values, were counteracted in rats. Assessments were made at 3 and 30min and 1, 3, 5, and 7 days after succinylcholine administration (1.0mg/kg into the right anterior tibial muscle)...

Staphylococcus epidermidis has become a major health hazard. It is necessary to study its metabolism and hopefully uncover therapeutic targets. Cultivating S. epidermidis at increasing oxygen concentration [O2] enhanced growth, while inhibiting biofilm formation. Respiratory oxidoreductases were differentially expressed, probably to prevent reactive oxygen species formation. Under aerobiosis, S. epidermidis expressed high oxidoreductase activities, including glycerol-3-phosphate dehydrogenase, pyruvate dehydrogenase, ethanol dehydrogenase and succinate dehydrogenase, as well as cytochromes bo and aa3; while little tendency to form biofilms was observed...

In Nature, no individual can live in isolation; hence, living organisms are forced to interact with each other. This necessity has led many organisms to establish heterogeneous relations to enhance their ability to adapt to the environment, thus acquiring evolutionary advantages. These relationships are sometimes so intense, that on the long term the organisms may lose their individual identity. An example of these associations is the endosymbiotic ones, where eukaryote organisms generally harbor different prokaryote organisms...

Mycobacterial species have practically evolved along humankind, sometimes provoking serious diseases. Among them, tuberculosis (TB), produced by M. tuberculosiscomplex bacteria, is historically the single most devastating infectious agent. Like many other microorganisms, M. tuberculosis resistant to antibiotics have risen as a consequence of selective pressure for mutants able to persist despite being attacked with drugs that would otherwise erradicate them from the infected person. Given the current long-term (6-9 months) therapy with multiple antibiotics, many people abandon their treatments, therefore promoting that bacteria that were not eliminated during therapy get exposed to suboptimal antibiotic concentrations, probably leading to mutations and drug resistance...

After the great epidemic of the exanthematic typhus of 1918-1919 in Chile, there was a gradual decrease in the number of cases , until it became endemic around 1926. Starting in 1932 and until 1939 a new epidemic outbreak occured that prompted researchers to its study supported by the new clinical and technological advances of this period. Subsequently, two important events occured: the erradication of the vector ( human louse) by means of effective insecticides and the discovery of an effective antibiotic treatment...

With the aim to erradicate Enzootic Bovine Leukosis from Poland, a more sensitive real-time polymerase chain reaction was required and developed to detect proviral Bovine leukaemia virus (BLV) DNA, the causative agent of Enzootic Bovine Leukosis (EBL). This new method proved more sensitive for our needs, than the current protocols available in the public domain. DNA was extracted from peripheral blood leukocytes of 51 cattle, which had given rise to doubtful serological test results by ELISA, and from mesenteric lymph nodes of six cattle that were slaughtered as EBL suspect cases...

Just say NO to biofilms: NO-donors are used to disperse a bacterial biofilm so that co-administered antibiotics will kill the more susceptible unattached cells. The chemically stable cephalosporin-3'-diazeniumdiolate NO-donor prodrug is activated by bacterial β-lactamases and facilitates this two-step biofilm erradication.

Diabetes is a chronic disease and as a consequence of the overproduction of reactive oxygen species (ROS), is related with oxidative stress. There are different sources of ROS, of which mitochondria is the main one. Oxidative stress seems to play an important role in mitochondria- mediated disease processes, though the exact molecular mechanisms responsible remain elusive. There are evidences which supports the idea that impaired mitochondrial function is a cause of the insulin insensitivity in different type of cells that arised as a result of an insufficient supply of energy or defects in the insulin signaling pathway...

BACKGROUND: Sequential therapy is used as an alternative to growing antibiotic resistance of Helicobacter pylori to the standard triple therapy. Despite the success it had in Europe, we have no information regarding this therapy in our region. OBJECTIVES: To evaluate the eradication rate of Helicobacter pylori using sequential therapy and show its adverse effects. METHODS: We performed a prospective, observational, open descriptive study. 31 patients were evaluated who were treated with sequential therapy in the following way: the first 5 days omeprazole 20 mg and amoxicillin 1 g every 12 hours and following 5 days omeprazole 20 mg, clarithromycin 500 mg and tinidazole 500 mg every 12 hours...

Radiation therapy (radiotherapy) is the medical use of ionizing radiation as part of cancer treatment to erradicate malignant cells. Normal tissue tolerance is currently a major dose-limiting factor. As molecular oxygen plays a critical role in creating the radiation damage, we propose a novel approach, that is, the use of acoustic radiation force (ARF) to suppress the normal tissue oxygenation, for the purpose of protecting the normal tissue and increasing its tolerance during radiotherapy. This paper investigated the effects of ARF on tissue oxygenation...
