STUDY OF AIR POLLUTION WITH COMBUSTION PRODUCTS OF GAS STOVES IN GAS-SUPPLIED APARTMENTS

Architecture and Engineering, 2018
As opposed to other fuel combustion appliances, in case of gas stoves, combustion products are released directly into the apartment air. Some people actually spend much time in such environment.

Maximum likelihood and the single receptor [PDF]

, 2009
Biological cells are able to accurately sense chemicals with receptors at their surfaces, allowing cells to move towards sources of attractant and away from sources of repellent. The accuracy of sensing chemical concentration is ultimately limited by the random arrival of particles at the receptors by diffusion.

The W ater Qua l ity Assessment According to the Nitrogen Compounds Content [PDF]

, 2011
Методами фотометричного й потенціометричного аналізів визначено вміст іонів амонію, нітрит- та нітрат-іонів у воді озера Сомин. Встановлено, що вміст досліджуваних іонів в основному не перевищує гранично допустимих норм.

A comparative study of circulating tumor cell isolation and enumeration technologies in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells were spiked into donor blood to evaluate the recovery rates of the following circulating tumor cell (CTC) enrichment technologies: CellMag™, EasySep™, RosetteSep™, Parsortix® PR1, and Parsortix® Prototype systems. Each method's advantages and disadvantages are described.

Cellular liquid biopsy provides unique chances for disease monitoring, preclinical model generation and therapy adjustment in rare salivary gland cancer patients

Molecular Oncology, EarlyView.
We quantified and cultured circulating tumor cells (CTCs) of 62 patients with various cancer types and generated CTC‐derived tumoroid models from two salivary gland cancer patients. Cellular liquid biopsy‐derived information enabled molecular genetic assessment of systemic disease heterogeneity and functional testing for therapy selection in both ...

High-excitation emission lines near eta Carinae, and its likely companion star [PDF]

Astrophys.J.710:729-742,2010, 2009
In order to study the distribution of gas and ionizing radiation around eta Car and their implications for its likely companion star, we have examined high-excitation emission lines of [Ne III], [Fe III], etc., in spectra obtained with the HST/STIS instrument during 1998-2004. Our principal results, some of them unexpected, are: (1) The high-excitation

Circulating tumor DNA (ctDNA) trajectories predict survival in trifluridine/tipiracil‐treated metastatic colorectal cancer patients

Molecular Oncology, EarlyView.
The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...
