Deton is Developing “Aerosol Biopsy” to Detect Lung Diseases

Biopsies and bronchoscopies are the gold standard for diagnosing lung diseases, including pneumonia and cancer. However, these procedures are difficult to provide, requiring general anesthesia and an operating room. Deton hopes to simplify the proces...

This article presents a unique 3D biocompatible Aluminum-based quantum structure (QS) for in vitro cancer detection using Surface Enhanced Raman Scattering (SERS). The Al-based QSs fabricated using ultrashort pulsed laser are of two distinct surface characters, wrinkled and smooth spherical. The limit of detection for chemical sensing of Crystal Violet and Rhodamine 6G by the Al-QS was driven up to single molecule sensing (femtomolar concentration). Biological sensing of cysteine, a disease biomarker and carcinoembryonic antigen (CEA), a cancer biomarker was also tested by the Al-QS. The ability of in vitro cell detection ...

In this study, four different weight% of Punica granatum fruit peel extract were used as green stabilizers to synthesize IONPs followed by a series of characterization experiments and in vitro anticancer evaluation. Results revealed that all synthesized IONPs have high degree of crystallinity and purity. The optimum saturation magnetization, and hydrodynamic size were found to be ∼69 emu.g−1, and 26.52 nm, respectively. Morphological studies demonstrated that adding peel extract decreased size of NPs with the average particle size below 11 nm. Cytotoxicity assay showed that the IONPs were not react...

Villanueva-Toledo, G.J. Mena-RejónAbstractThe structural modification of natural products has shown to be a remarkable tool in the generation of novel bioactive molecules. Herein, the synthesis, structural analysis and anticancer activity of the novel triterpenoid thiazole 3 is reported. The synthesis was carried out through the bromination of ochraceolide A (1) and the subsequent heterocyclic condensat...

GudasAbstractEthanol (EtOH) is a recreationally ingested compound that is both teratogenic and carcinogenic in humans. Because of its abundant consumption worldwide and the vital role of stem cells in the formation of birth defects and cancers, delineating the effects of EtOH on stem cell function is currently an active and urgent pursuit of scientific investigation to explicate some of the mechanisms contributing to EtOH toxicity. Stem cells represent a primordial, undifferentiated phase of devel...

Therefore, monitoring the changing of intracellular polarity can great improve the understanding its functions in living cell level. Herein, by employing p-phenylenediamine as precursor, we prepared a red emissive carbon dots based nanoprobe for real-time sensing polarity in living cells. With the i...

Gibril, Fangong KongAbstractApplication of the lignin-based monomer in polymers synthesis will reducing the use of petrochemical-based monomers, enhance the polymer/copolymers properties, and disposing lignin in a profitable way. Accordingly, in this work, the lignin-vinyl acetate monomer (LVAc) and its copolymers were synthesized successfully. To obtain the LVAc, firstly, lignin was activated with the amine using diethylenetriamine (DETA) and then followed by the grafting with chlorovinyl aceta...

In this study four kinds of fingerprints, including sweat, inkpad, sunscreen, and liquid foundation, were analyzed by air-flow assisted desorption electrospray ionization mass spectrometry imaging (AFADESI-MSI). AFADESI was employed with air flow of 45 L min−1, and 5 μL min−1 acetonitrile was used as spray solvent at spray voltage of 7000 V. Positive ion full scan mode (100−1000 Da) was chosen. The results showed that AFADESI-MSI method could not only obtain chemical information of various endogenous and exogenous substances in fingerprints, but also obtain high resolution images of fingerprints. In ad...

Smoke-measuring smart shirts, breath sound analyzing algorithms, and smart inhalers pave the way of pulmonology and respiratory care into the future. As the number of patients suffering from asthma, COPD, or lung cancer due to rising air pollution and steady smoker-levels will unfortunately not decrease any time soon, we looked around what technology can do to help both patients and caregivers. The results are breathtaking. Attacks of breathlessness are too common The diseases which pulmonologists and respiratory care specialists attempt to fight are among the most common conditions in the modern world – and t...
