Abstract The anecdotal use of Alternanthera sessilis L. as a relief for diabetes has been known in the Philippines for generations, and antidiabetic activity of similar varieties in other countries is likewise documented. However, the compounds responsible for this activity remain unclear. This study aim...
Among the management and control tactics of the coffee berry borer Hypothenemus hampei (Ferrari), there is the use of entomopathogenic fungi. Due to the importance of prospecting isolates of entomopathogenic fungi for the control of the coffee berry borer, the objective of this study was to evaluate the ...
Abstract Instrumental techniques are preferred over bioassay methods for antibiotic quantification mainly due to speed and ability to quantify metabolites in biological samples; however, the potency and biological activity of these drugs cannot be assessed. Two methods - agar well diffusion (bio-assay) a...

BACKGROUND:
Long non-coding RNAs (lncRNAs), as post-transcriptional regulators, were thought to function in the inductive property of dermal papilla cells (DPCs) in cashmere goat. Previously, lncRNA-599554 was identified in secondary hair follicle (SHF) of cashmere goat, but its functional significance i...

Abstract INTRODUCTION: Rapid and accurate tuberculosis detection is critical for improving patient diagnosis and decreasing tuberculosis transmission. Molecular assays can significantly increase laboratory costs; therefore, the average time and economic impact should be evaluated before implementing a ...

Abstract A novel microbiological system in microtiter plates consisting of five bioassays is presented for the detection and classification of antibiotic residues in milk. The bioassays were optimized for the detection of beta-lactams (Bioassay B: Geobacillus stearothermophilus), macrolides (Bioassay M: ...
Plant species have been used for therapeutic purposes since ancient times and are still in use today since these products represent a source of raw material for the production of phytotherapeutic formulations. Screening and investigation of plants with pharmacological potential require the evaluation of ...

Recombinant human interferon beta 1b (rhIFNβ-1b) is clinically used to treat multiple sclerosis. A reversed-phase liquid chromatography (RP-LC) method was carried out on a Jupiter C4 column (250 mm × 4.6 mm i.d.). The mobile phase A consisted of 0.1% trifluoroacetic acid (TFA) in water, and the mobile ...
O estudo avalia a toxicidade, citotoxicidade, genotoxicidade e análises físico-químicas e microbiológicas de amostras de águas coletadas em dois pontos (nascente e foz) do Rio da Ilha - um dos principais afluentes do Rio dos Sinos, RS, Brasil - em dois períodos: inverno (2014) e verão (2015), atra...
