4-Hydroxyphenylpropan-7,8-diols and derivatives from Narvalina domingensis
(Phytochemistry, 1996)
Investigation of a Haitian medicinal plant, Narvalina domingensis, afforded, erythro- and threo-4-hydroxyphenylpropan-7,8-diol and their 7-O- methyl ether, 7-O-ethyl ethers and 4-O-isovaleric acid esters. The structures ...
Autophagy: A Key Regulator of Homeostasis and Disease: An Overview of Molecular Mechanisms and Modulators
(Cells, 2022)
Autophagy is a highly conserved lysosomal degradation pathway active at basal levels
in all cells. However, under stress conditions, such as a lack of nutrients or trophic factors, it
works as a survival mechanism that ...
The acute care diagnostics collaboration: Performance assessment of contrast-enhanced ultrasound compared to abdominal computed tomography and conventional ultrasound in an emergency trauma score bayesian clinical decision scheme
(Wolters Kluwer, 2023)
Bayes’ theorem describes the probability of an event, based on conditions that might be related to the event. We developed the Bayesian Diagnostic Gains (BDG) method as a simple tool for interpreting diagnostic impact. We ...
Adaptive digital access protocol: a MAC protocol for multiservice broadband access networks
(IEEE Communications Magazine, 1996-03)
The authors describe a protocol that can adapt to the changing demands of a mix of synchronous transfer mode (STM) and asynchronous transfer mode (ATM) applications and efficiently allocate bandwidth to a variety of bursty ...

This paper makes a comparative analysis of the first bricks manufactured in the New World during the first 50 years of conquest and colonization (1494–1544). Samples of bricks and tiles were taken from the sites of the ...
Trace element determination of mercury by total-reflection X-ray fluorescence
(Spectrochimica Acta Part B: Atomic Spectroscopy, 1997-07-01)
A rapid and simple method is presented for the determination of trace amounts of ionic mercury in solutions by total-reflection X-ray fluorescence. The method relies on the formation of a mercury amalgam on a 50 nm thick ...
Determination of traces of heavy metals in estuarine waters of Barbacoas Bay, Colombia, by X-Ray fluorescence spectrometry
(1998-12-04)
An evaluation of metal contamination in estuarine waters and shrimp culture systems was conducted using two analytical processes: soluble metals were examined by radioisotope x-ray fluorescence spectrometry (RIXRF) and ...

(Plos Medicine, 2021)
The World Health Organization (WHO) has reframed health and healthcare for older people
around achieving the goal of healthy ageing. The recent WHO Integrated Care for Older
People (ICOPE) guidelines focus on maintaining ...
Correction to: Patterns and Effects of Admission Hyperglycemia and Inflammatory Response in Trauma Patients: A Prospective Clinical Study
(World J Surg, 2021)
The constellation of the initial hyperglycemia, proinflammatory cytokines and severity of injury among
trauma patients is understudied. We aimed to evaluate the patterns and effects of on-admission hyperglycemia and ...
