Esophageal stenting for unresectable cancer (review of literature)

open access: yesВестник хирургии имени И.И. Грекова, 2021
To date, the main way to stop dysphagia for patients with unresectable esophageal cancer is stenting. Being widely accepted and effective, this technique, however, allows for oral nutrition only for an average of 3–4 months and is accompanied by the ...

Absolute quantification in multi-pinhole micro-SPECT for different isotopes [PDF]

open access: yes, 2011
In preclinical Single Photon Emission Tomography (SPECT), absolute quantification is interesting, expressed in percentage of injected radioactive dose per gram of tissue.

Triaxiality in the odd-A nuclei 109−117I studied through a microscopic rotationparticle coupling

open access: yesEPJ Web of Conferences, 2018
A systematic study of ground state spectrum with the triaxial deformation γ for odd-A Iodine isotopes 109−117I is carried out with the nonadiabatic quasiparticle approach.

A Generalized Approach for Distal C–H Arylation of Organic Building Blocks: Unveiling the Role of Counter Anion

open access: yesAdvanced Science, EarlyView.
We report a general strategy for meta‐selective C–H arylation using aryl iodides and a Pd(II)/Pd(IV) catalytic system guided by a removable directing group. DFT and experimental studies reveal that counter anion tuning (acetate to trifluoroacetate) significantly enhances selectivity.

Legacy of Dr. Saul Hertz [PDF]

open access: yesТерапевтический архив
Saul Hertz was a physician and scientist who invented and implemented the use of radioactive iodine (RAI) for medical purposes. The history of the development of this new non-invasive and effective method of treatment began in 1936, when Saul Hertz asked

On the Origin of the Early Solar System Radioactivities. Problems with the AGB and Massive Star Scenarios [PDF]

open access: yes, 2018
Recent improvements in stellar models for intermediate-mass and massive stars are recalled, together with their expectations for the synthesis of radioactive nuclei of lifetime $\tau \lesssim 25$ Myr, in order to re-examine the origins of now extinct ...

The puzzles of dark matter searches

open access: yes, 2009
Positive results of dark matter searches in DAMA/NaI and DAMA/LIBRA experiments, being put together with negative results of other groups, can imply nontrivial particle physics solutions for cosmological dark matter.

Iron deficiency up-regulates iron absorption from ferrous sulphate but not ferric pyrophosphate and consequently food fortification with ferrous sulphate has relatively greater efficacy in iron-deficient individuals [PDF]

open access: yes, 2011
Fe absorption from water-soluble forms of Fe is inversely proportional to Fe status in humans. Whether this is true for poorly soluble Fe compounds is uncertain.

Adsorptive Removal of Gaseous Methyl Iodide by Triethylenediamine Modified Activated Carbon Fiber

open access: yesYuanzineng kexue jishu, 2023
The rapid growth of the nuclear industry poses a great challenge for radioactive waste treatment. Volatile radioactive isotopes generated from uranium fission, especially gaseous iodine, attracted great attention due to their environment and health ...
