Lumino-structural properties of Dy activated NaBaLaNbO phosphors with enhanced internal quantum yield for w-LEDs.

With an intend to develop white light emitting phosphor, for w-LED application, a series of dysprosium (Dy) doped novel NaBaLaNbO phosphors were prepared using solid state reaction technique at 1300 °C. Their structural, morphological and vibrational spectroscopic analysis was performed. We illustrate the luminescence characteristics of the prepared phosphors for various Dy ion doping concentration.

Oblique plane microscope for mesoscopic imaging of freely moving organisms with cellular resolution.

Several important questions in biology require non-invasive and three-dimensional imaging techniques with an appropriate spatiotemporal resolution that permits live organisms to move in an unconstrained fashion over an extended field-of-view. While selective-plane illumination microscopy (SPIM) has emerged as a powerful method to observe live biological specimens at high spatio-temporal resolution, typical implementations often necessitate constraining sample mounting or lack the required volumetric speed. Here, we report on an open-top, dual-objective oblique plane microscope (OPM) capable of observing millimeter-sized, freely moving animals at cellular resolution.

Endogenous tagging of multiple cellular components in the sea anemone .

The cnidarian has developed into a powerful model system to study the mechanisms underlying animal development, regeneration, and evolution. However, despite the significant progress in the molecular and genetic approaches in this sea anemone, endogenous protein tagging is still challenging. Here, we report a robust method for knock in for using CRISPR/Cas9.

Effect of integrating industrial and agricultural wastes on concrete performance with and without microbial activity.

Cement is an essential material used in constructional activities. An emerging concern in the industry however is the CO emissions, which are triggered by cement manufacturing units. These emissions can be controlled to some extent by not using cement exclusively and instead replacing a percentage of it with waste material with properties similar to cement.

Quantitative assessment of morphology and sub-cellular changes in macrophages and trophoblasts during inflammation.

In pregnancy during an inflammatory condition, macrophages present at the feto-maternal junction release an increased amount of nitric oxide (NO) and pro-inflammatory cytokines such as TNF- and INF-γ, which can disturb the trophoblast functions and pregnancy outcome. Measurement of the cellular and sub-cellular morphological modifications associated with inflammatory responses are important in order to quantify the extent of trophoblast dysfunction for clinical implication. With this motivation, we investigated morphological, cellular and sub-cellular changes in externally inflamed RAW264.

Rehabilitation of an ocular defect with intraorbital implant and custom-made prosthesis using digital photography and gridded spectacle.

Accidental trauma involving the eye may necessitate surgical removal of the eye ball. Immediate management should consider future prosthetic rehabilitation. Insertion of eye ball implant after enucleation or evisceration preserves socket anatomy, maintains sulcus and fornix which ensures proper retention of ocular prosthesis in future.

Workshop on Pesticide Exposure Assessment Paradigm for Non-Apis Bees: Foundation and Summaries.

Current pesticide risk assessment practices use the honey bee, Apis mellifera L., as a surrogate to characterize the likelihood of chemical exposure of a candidate pesticide for all bee species. Bees make up a diverse insect group that provides critical pollination services to both managed and wild ecosystems.

Pesticide Exposure Assessment Paradigm for Solitary Bees.

Current pesticide risk assessment for bees relies on a single (social) species, the western honey bee, Apis mellifera L. (Hymenoptera: Apidae). However, most of the >20,000 bee species worldwide are solitary.

Multi-modal chip-based fluorescence and quantitative phase microscopy for studying inflammation in macrophages.

Total internal reflection fluorescence (TIRF) microscopy benefits from high-sensitivity, low background noise, low photo-toxicity and high-contrast imaging of sub-cellular structures close to the membrane surface. Although, TIRF microscopy provides high-contrast imaging it does not provide quantitative information about morphological features of the biological cells. Here, we propose an integrated waveguide chip-based TIRF microscopy and label-free quantitative phase imaging (QPI).

Exposure to aged crumb rubber reduces survival time during a stress test in earthworms (Eisenia fetida).

Solid waste management struggles with the sustainable disposal of used tires. One solution involves shredding used tires into crumb rubber and using the material as infill for artificial turf. However, crumb rubber contains hydrocarbons, organic compounds, and heavy metals, and it travels into the environment.

Determinants of supply chain coordination of milk and dairy industries in Ethiopia: a case of Addis Ababa and its surroundings.

Coordination of different business activities among units becomes vital as organizations pay much attention to their core activities. Thus, their fruitfulness constantly relies on their capacity to coordinate their internal and external activities in the supply chain outside their own boundaries. Giving consideration to these obvious reasons, this paper aims to investigate the determinants of supply chain coordination of milk and dairy industries.

Herpes genitalis - Topical zinc sulfate: An alternative therapeutic and modality.

Background: Herpes genitalis is one of the commonest sexually transmitted infections in the world caused by herpes simplex virus (HSV) 1 and 2. All herpes viruses show latency. Herpes genitalis caused by HSV-1 and HSV-2 is recurrent in 55 and 90% of case respectively.

Cross-species transmission of honey bee viruses in associated arthropods.

There are a number of RNA virus pathogens that represent a serious threat to the health of managed honey bees (Apis mellifera). That some of these viruses are also found in the broader pollinator community suggests the wider environmental spread of these viruses, with the potential for a broader impact on ecosystems. Studies on the ecology and evolution of these viruses in the arthropod community as a whole may therefore provide important insights into these potential impacts.

Full-mouth rehabilitation of a patient with severe attrition using the Hobo twin-stage procedure.

Excessive occlusal wear can result in pulpal injury, occlusal disharmony, impaired function and aesthetic deformity. Loss of anterior guidance can result from severe wear of anterior teeth, which protects the posterior teeth during excursive movement. The collapse of posterior teeth also results in the loss of normal occlusal plane and the reduction of the vertical dimension.

Dyschromatosis universalis hereditaria: a rare entity.

Dyschromatosis universalis hereditaria is an infrequently occurring genodermatosis with peculiar pigmentary changes, consisting of varying sized, intermingled hyperpigmented and hypopigmented macules that give an overall impression of mottling. We hereby report a case of dyschromatosis universalis hereditaria in a young female with a family history of the disorder.

Bioefficacy and mode-of-action of some limonoids of salannin group from Azadirachta indica A. Juss and their role in a multicomponent system against lepidopteran larvae.

Biological activities of the salannin type of limonoids isolated from Azadirachta indica A. Juss were assessed using the gram pod borer Helicoverpa armigera (Hubner) and the tobacco armyworm Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae). Inhibition of larval growth was concomitant with reduced feeding by neonate and third instar larvae.
