Observational: studies in human beings in which biomedical and/or health outcomes are assessed in pre-defined groups of individuals. Subjects in the study may receive diagnostic, therapeutic, or other interventions, but the investigator does not assign specific interventions to the subjects of the study.
Study Phase Definition: Phase of investigation, as defined by the US FDA for trials involving investigational new drugs. Select only one.
N/A: for trials without phases Observational Study Design Case-control: group of individuals with specific characteristics (e.g., conditions or exposures) compared to group(s) with different Time Perspective Cross-sectional: observations or measurements made at a single point in time, usually at subject enrollment Biospecimen Retention - select one Samples Without DNA - samples retained, with no potential for DNA extraction from any retained samples (e.g., fixed tissue, plasma) Biospecimen Description
Sputum, whole blood, urine, tissue Enrollment
Single group study Number of Groups/Cohorts Definition: Number of study groups/cohorts. Enter 1 for a single-group study. Many observational studies have one group/cohort; case control studies typically have two.
One study group, anticipated samples in the rang of 400-500 samples 8. Arms, Groups and Interventions N/L Group/Cohort Label

The purpose of this study is to provide a mechanism for the emergency use of tigecycline in the appropriate clinical situations. The secondary objective is to evaluate the safety and effi...
In light of tigecycline's activity against these resistant bacteria, tigecycline may represent a viable new therapy for complicated intra-abdominal infections.
Purpose: To provide a mechanism for the emergency use of tigecycline in the appropriate clinical situations.
Tigecycline's activity against resistant organisms, as well as significant coverage of both gram-positive and gram-negative bacteria, may provide a valuable therapeutic alternative in trea...
The purpose of this study is to compare the safety and efficacy of the antibiotic tigecycline with other antibiotics, ampicillin-sulbactam, and amoxicillin-clavutanate in the treatment of ...
Acinetobacter baumannii is a major cause of nosocomial infections worldwide. Therapeutic options in management of this bacteria are limited. Tigecycline is considered as an alternative treatment of in...
Reduced susceptibility to tigecycline (TIG) is increasing. We aimed to analyze the in vitro activity of TIG against Enterococcus recovered from hospitalized patients and to evaluate the effect of omep...
Chlamydia is a group of bacterial pathogens distributed worldwide that can lead to serious reproductive and other health problems. The rise of antibiotic-resistant pathogens promotes the development o...
The secretion of proteins that damage host tissue is well established as integral to the infectious processes of many bacterial pathogens. However, recent advances in our understanding of the activity...
Klebsiella pneumoniae is an opportunistic pathogen and many strains are multidrug resistant. KPC is one of the most problematic resistance mechanisms, as it confers resistance to most β-lactams, incl...
A fluorescent probe with low toxicity which is a potent substrate for P-glycoprotein and the bacterial multidrug efflux transporter. It is used to assess mitochondrial bioenergetics in living cells and to measure the efflux activity of P-glycoprotein in both normal and malignant cells. (Leukemia 1997;11(7):1124-30)
A pattern recognition receptor that binds unmethylated CPG CLUSTERS. It mediates cellular responses to bacterial pathogens by distinguishing between self and bacterial DNA.
The concentration of a compound needed to reduce population growth of organisms, including eukaryotic cells, by 50% in vitro. Though often expressed to denote in vitro antibacterial activity, it is also used as a benchmark for cytotoxicity to eukaryotic cells in culture.
A fungal metabolite which is a macrocyclic lactone exhibiting a wide range of antibiotic activity.
The techniques used to produce molecules exhibiting properties that conform to the demands of the experimenter. These techniques combine methods of generating structural changes with methods of selection. They are also used to examine proposed mechanisms of evolution under in vitro selection conditions.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
