background: diagnosis of cutaneous leishmaniasis (cl) is often made based on clinical manifesta­tion. correct diagnosis and identification of the parasite are crucial for choosing the effective treat­ment and for epidemiological studies. on the other hand, determination of leishmania species is nec­essary for designing appropriate control programs. diagnosis by pcr is becoming a 'gold standard'...

This study involves in vitro androgenesis of Zea mays L. via anther culture. In the first experiment, three embryo induction media were tested in ETH-M82 genotype of maize. The results showed that the embryo structures were established 2 to 3 weeks after culturing the anthers. The effect of induction medium was signifi­cant for embryo frequencies. The obtained results confirm that the induction...

Distinguishing a specific biomarker from a biofluid sample containing a large variety of proteins often requires the selective preconcentration of that particular biomarker to a detectable level for analysis. Low-cost, paper-based device is an emerging opportunity in diagnostics. In the present study, we report a novel Zinc oxide nanorods functionalized paper platform for the preconcentration o...

RATIONALE Various disease conditions, particularly tumours, can be understood easily by studying changes in the lipid profile of cells. While lipid profiles of tissues have been recorded by desorption electrospray ionization mass spectrometric (DESI-MS) imaging, there is paucity in standardized protocols for sample preparation involving cell cultures to generate reliable results. In this study,...

BACKGROUND Identification of the source of mosquito blood meals is an important component for disease control and surveillance. Recently, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) profiling has emerged as an effective tool for mosquito blood meal identification, using the abdomens of freshly engorged mosquitoes. In the field, mosquito abdomens a...
