background: immunochromatographic based rk39 antibody detection test became popular for the diagnosis of visceral leishmaiasis (vl) because of high sensitivity, rapidity, easy to interpret, and cost effectiveness. however, false positive result after complete cure of the patients is the major limitation with this test. the aim of the study to access the usefulness of non-invasive samples i.e. ...
We present a novel noninvasive technology for quality control in biobanking. We implemented a contactless optical in situ method with a remote detection unit. The method detects physical and chemical changes by emission spectroscopy. In the present study, ice formation in a vitrified sample is revealed by Raman scattering. The technology allows us to monitor sample quality during cold storage a...
conclusions: rsbi and apache ii score in patients with copd exacerbation are of the ability to predict niv requirement, as a predicting factor of non-invasive ventilation requirement. results: patients requiring niv included 43.9 % of all studied patients. rsbi and apache ii score with sensitivity of 94.8 %, (cut off point = 110) and 72 % (cut off point = 14) respectively, had high diagnostic s...
BACKGROUND Analysis of aberrant hypermethylation in stool DNA might provide a novel strategy for noninvasive detection of colorectal cancer. AIMS To explore the feasibility of detecting hypermethylation in Spastic paraplegia-20 promoter as a stool-based DNA marker for detection of colorectal cancer. METHODS We collected 96 tissue and stool samples from patients with colorectal cancer and 30...
Background and Aim: Blood samples are used for the diagnosis of many diseases. Serum ferritin level is known to be a marker of anemia and iron overload disorders. However, blood collection is an invasive method. Saliva, as a bio-fluid, contains a va-riety of important components that are successfully used for assessment of body health. The use of saliva samples for ferritin evaluation can be re...
abstractneuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. it is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. neuroimaging modalities include x-ray computed tomography (ct), magnetic resonance imaging (mri), single photon emis...
background: pneumocystis carinii is one of opportunistic organisms especially in immuno-compromised patients. for years, diagnosis of pneumocystis pneumonia (pcp) has relied on microscopic visualization of organism in specimens obtained from the lung either by bronchoalveolar lavage (bal) or by induction of sputum, but failed to provide efficient diagnosis. the aim of this study was to compare ...
Noninvasive genetic sampling provides great potential for research and management applications in wildlife biology. llesearchers can obtain DNA from a variety of sources including hair, feces, urine, feathers, shed skin, saliva, and egg shells without handling or observing animals. These samples can then be used to identify the presence of rare or elusive species, count and identify individuals...
