Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]

open access: yesarXiv, 2006
The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each

The role of heat shock proteins in placental ischemic disease: A narrative review of the current literature

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 3, Page 960-967, June 2025.
Abstract Pre‐eclampsia, placental abruption, and fetal growth restriction (FGR) are collectively referred to as placental ischemic disease (PID). Heat shock proteins (HSPs), originally considered as a response to the heat shock, have a central role in regulating the cellular functions by quality controlling the newly synthesized proteins.

The Factors of the Classification of Protein Amino Acids [PDF]

open access: yesThis paper is published in GLASNIK of Montenegrin Academy of Science and arts, 2000, 13, pp. 173-194, 2006
In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).

A flexible MRF approach to improve kinetic rate estimation with bSSFP‐based hyperpolarized [1‐13C]pyruvate MRI

open access: yesMagnetic Resonance in Medicine, Volume 93, Issue 6, Page 2263-2277, June 2025.
Abstract Purpose In this work, we adopt the MR fingerprinting (MRF) framework and leverage its flexibility in quantitative pulse sequence design to propose improved balanced steady‐state free precession (bSSFP)–based hyperpolarized Carbon‐13 (13C) acquisitions for robust metabolic conversion rate quantification. Methods Spectrally selective bSSFP‐based

The relation of pyruvic acid to carbohydrate metabolism. [PDF]

open access: yes, 1919
It is known that carbohydrates on oxidation break into fragments which later are oxidised, or reduced, according as the conditions of the bodily functioning may favor, and it is in this process or reaction of the carbohydrate molecule that the formation ...

Benzodiazepine and Opioid Withdrawal Induced Neuroleptic Malignant Like Syndrome: A Clinical Case Report With Management Complexities

open access: yesNeuropsychopharmacology Reports, Volume 45, Issue 2, June 2025.
This case report describes a 54‐year‐old man who developed Neuroleptic Malignant‐like Syndrome (NMLS) following the abrupt withdrawal of high‐dose benzodiazepines and opioids. The report highlights the diagnostic challenges in differentiating NMLS from Neuroleptic Malignant Syndrome and emphasizes the critical role of GABAergic dysregulation in its ...

ISG15 Enhances the Activity of γ‐Glutamate Cysteine Ligase to Suppress Apoptosis in High Fat Diet‐Promoted Hepatocellular Carcinoma

open access: yesAdvanced Science, Volume 12, Issue 19, May 22, 2025.
Hepatocellular carcinoma (HCC) cells under high‐fat environment constrain harmful reactive oxygen species (ROS) by enhancing glutathione synthesis though upregulating interferon stimulated gene 15 (ISG15). In this process, upregulated high mobility group A1 (HMGA1) enhances ISG15 transcription, upregulated ISG15 subsequently noncovalently binds with ...

Evaluation of physical and chemical characteristics of xanthan gums

open access: yesSemina: Ciências Exatas e Tecnológicas, 2007
This work aimed at evaluating the physical and chemical characteristics of the xanthan produced by Xanthomonas arboricola pv pruni strain 115, and at comparing it with two xanthans obtained from commercial sources – Kelzan e Roeper. The analyzed xanthans

Mitochondrial Complex I Deficiency: Unraveling the Relevance of NDUFAF1 in Pediatric Hypertrophic Cardiomyopathy

open access: yesAmerican Journal of Medical Genetics Part A, Volume 197, Issue 5, May 2025.
ABSTRACT Hypertrophic cardiomyopathy (HCM) is rare in childhood, but it is associated with significant morbidity and mortality. Genetic causes of HCM are mostly related to sarcomeric genes abnormalities; however, syndromic, metabolic, and mitochondrial disorders play an important role in its etiopathogenesis in pediatric patients.
