Psychological Components of Disease Stigma Across Illnesses: Associations with Cultural and Personal Factors

Understanding public stigma against patients (also known as disease stigma)—negative attitudes or discriminatory responses toward individuals with a disease—is essential for improving health outcomes and fostering inclusive communities. In ...

Fertility and Iron Bioaccumulation in <i>Drosophila melanogaster</i> Fed with Magnetite Nanoparticles Using a Validated Method

Research on nanomaterial exposure-related health risks is still quite limited; this includes standardizing methods for measuring metals in living organisms. Thus, this study validated an atomic absorption spectrophotometry method to determi...

Evaluation of microhardness of residual dentin in primary molars following caries removal with conventional and chemomechanical techniques: An In vitro Study

Background: Many patients consider removal of caries to be a very unpleasant experience. Removal of caries with conventional drill is considered traumatic mainly due to fear and anxiety of children and their parents. Minimally invasive dent...

Assessment of role of PPE in preventing the spread of infection among the dental surgeons: A prospective study

Although there is easy accessibility of infection control measures and recommendation regarding the PPE, most of the dentists failed to practice appropriate infection control measures. The aim of the current survey was conducted to assess t...

Synthesis of a Pseudodisaccharide α-C-Glycosidically Linked to an 8-Alkylated Guanine

The synthesis of stable guanofosfocin analogues has attracted considerable attention in the past 15 years. Several guanofosfocin analogues mimicking the three constitutional elements of mannose, ribose, and guanine were designed and synthes...

Identification of Lichen Based on Substrate in Bale Village, Tanantovea District, Donggala Regency

Lichens are associations between fungi and photosynthetic symbionts, such as algae or cyanobacteria, that form stable and specialized thallus structures. The fungi that predominantly compose the lichen body belong to the Ascomycetes, while ...

A nova lei de patentes, a indústria química e a universidade

International Conference on Green Chemistry and Sustainable Engineering International (Barcelona, Spain, July 29–31, 2014)

1H High Resolution Magic-Angle Coil Spinning (HR-MACS) &#181;NMR Metabolic Profiling of whole Saccharomyces cervisiae cells: A Demonstrative Study

The low sensitivity of Nuclear Magnetic Resonance (NMR) is its prime shortcoming compared to other analytical methods for metabolomic studies. It relies on large sample volume (30–50 µl for HR-MAS) for rich metabolic profiling, hindering hi...

1,1-Dimethylbiguanidium(2+) dinitrate

In the crystal structure of the title compound, C4H13N52+&amp;#183;2NO3&amp;#8722;, the main intermolecular interactions are the N&amp;#8212;H...O hydrogen bonds between the cationic amino groups and the O atoms of the nitrate ions. All ami...

The Effect of Different Accelerators on the Vulcanization of EPDM Rubber

: EPDM (ethylene propylene diene monomer) is a type of synthetic rubber. The products of rubber have great importance in every part of life. EPDM rubber has high tensile strength, high tension, toughness, and is weather resistant. Therefore...

Glass-fiber catalysts for selective catalytic reduction of nitrogen oxides by CO and hydrocarbons

Glass-fiber catalysts (GFCs) are investigated in the process of the catalytic reduction of nitrogen oxides by hydrocarbons and carbon monoxide contained in waste and flue gases. Studies show that the platinum-based GFCs prepared by surface ...

Characterization of thermally treated polypropylene powders with wide sintering window for powder bed fusion of polymers

One key issue restricting semi-crystalline polymers to be widely applied in powder bed fusion (PBF) of polymers is lack of good powder processability, especially a wide sintering window. In this work, a thermal treatment method with mixed d...

Incorporation of Copper/Melamine Complexes in Silica Surface Andtheir Sorption Activity of Organic Dye

The efficiency and performance of supported melamine/ copper complexes, S/[CuCl2(Mel)2].2MeOH, as a new adsorbent, for the adsorptive removal of Indigo Carmine (IC) from aqueous solutions, has been evaluated with respect to several experime...

Engineered Bacterial Cellulose Nanostructured Matrix for Incubation and Release of Drug-Loaded Oil in Water Nanoemulsion

Bacterial cellulose (BC) is a highly pure form of cellulose produced by bacteria, which possesses numerous advantages such as good mechanical properties, high chemical flexibility, and the ability to assemble in nanostructures. Thanks to th...

Physicochemical characterization and source apportionment of Arctic ice-nucleating particles observed in Ny-Ålesund in autumn 2019

Ice-nucleating particles (INPs) initiate primary ice formation in Arctic mixed-phase clouds (MPCs), altering cloud radiative properties and modulating precipitation. For atmospheric INPs, the complexity of their spatiotemporal variations, h...

A STRAIGHTFORWARD SYNTHESIS OF NOVEL 1,3,5-TRIAZINE-BASED MACROCYCLIC SCAFFOLDS
