Green and Sustainable Chemistry Approaches on Azide‐Based Click Reactions in Polymer Science

Macromolecular Rapid Communications, EarlyView.
Click Chemistry, particularly the azide‐alkyne cycloaddition (AAC) reaction, has revolutionized polymer chemistry, enabling precise and efficient synthesis of advanced functional materials. With its high regioselectivity, mild reaction conditions, and versatility, AAC reactions align closely with the principles of Green and Sustainable Chemistry.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Primary erythromelalgia mainly manifested by hypertensive crisis: A case report and literature review

Frontiers in Pediatrics, 2022
BackgroundPrimary erythrocytic (PEM) is a rare autosomal dominant single gene disease. Most of the changes of gene loci can be found by whole exon gene sequencing, and the clinical symptoms and patient survival can be improved by specific site-to-site ...

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Nitroglycerin for Management of Retained Placenta: A Multicenter Study

Obstetrics and Gynecology International, 2012
The primary aim was to determine if sequential administration of oxytocin and nitroglycerin is effective for management of retained placenta when performed by obstetricians with no experience of the method. Secondary aims were to examine possible adverse

A Frailty‐Based Plasma Proteomic Signature Capturing Overall Health and Well‐Being in Older Adults

Aging Cell, EarlyView.
We derived a 25‐protein blood‐based frailty signature (proteomic frailty index, pFI) predictive of the cumulative frailty index. The pFI was validated across independent cohorts and was significantly associated with physical, clinical, and cognitive function, as well as incident mortality and dementia, highlighting its potential as a biomarker of ...

The effect of subcutaneous infiltration of nitroglycerin on the arterial cannulation under ultrasound guidance: a prospective randomized study

Bali Journal of Anesthesiology, 2023
Background: Ultrasound (US) guidance has not improved the success rate of radial artery cannulation to nearly 100%. This explains the other factors that can be improved to increase the success rate.

Human hypoxia models in aerospace medicine: Potential applications for human pharmacological research

British Journal of Clinical Pharmacology, EarlyView.
Aerospace medicine required controlled terrestrial models to investigate influences of altered atmosphere conditions, such as hypoxia, on human health and performance. These models could potentially be expanded to encompass disease conditions or treatment targets regulated through hypoxia or hypercapnia.
