Light-emitting diode fluorescence microscopy (LED-FM) is recommended by the World Health Organization to replace conventional Ziehl-Neelsen microscopy for pulmonary tuberculosis diagnosis. Uptake of LED-FM has been slow. One reason is its reported loss of specificity compared with Ziehl-Neelsen microscopy. We aimed to determine the diagnostic accuracy of LED-FM for tuberculosis detection and ex...

abstract planting of olive (olea europaea l.) tree due to salt and drought tolerance and ever green habit increasingly is considered in urban landscape in recent years. the low resistance to cold has been a major problem in using this tree in temperate and cold zones. so, determination of frost resistance cultivars is one of the important measures for use of this tree in urban landscape. to eva...

Flexibility of chloroplast thylakoid membrane proteins is essential for plant fitness and survival under fluctuating light environments. Phosphorylation of light-harvesting antenna complex II (LHCII) is known to induce dynamic protein reorganization that fine-tunes the rate of energy conversion in each photosystem. However, molecular details of how LHCII phosphorylation causes light energy redi...

The characterization of the most common photosynthetic biofilms in Nerja Cave by continuous monitoring vivo chlorophyll a (Chl ) fluorescence and incorporation irradiance as new environmental variable related to previous studies cave, have allowed us improve our knowledge about pattern cave. Effective quantum yield ( ΔF/Fm relative electron transport rate (rETR) were determined during periods l...

Cochlear implants allow most patients with profound deafness to successfully communicate under optimal listening conditions. However, the amplitude modulation (AM) information provided by most implants is not sufficient for speech recognition in realistic settings where noise is typically present. This study added slowly varying frequency modulation (FM) to the existing algorithm of an implant ...

The urban environment induces stress on trees and its impact can be identified by observing the condition of crown. aim this study is to correlate variables crown density (Cdn), transparency (Ctr) dieback (Cdie) with following vegetation indices: normalized difference index (NDVI), enhanced (EVI), blue-normalized (BNDVI), green-normalized (GNDVI), green–red (GRVI) red–green–blue (RGBVI) crowns ...

Soybean is an important legume food crop, and its seeds are rich in nutrients, providing humans animals with edible oil protein feed. However, soybean sensitive to water requirements, drought factor limiting yield quality. This study used Heinong 84 (drought resistant variety) Hefeng 46 (intermediate as tested varieties planted chernozem, albic, black soils. The effects of stress on the activit...

Neuroserpin, a member of the Serine Proteinase Inhibitor (Serpin) superfamily, is known to be a neuroprotective factor in the focal ischemic stroke followed by reducing the microglial activation. Neuroserpin is a protein rich of methionine residues that can scavenge the free radical species which may increase its neuroprotective effect. On the other hand, the oxidative modifications of the amin...
