Intermolecular Enzymatic Encoding of Nucleic Acid, Steroid Complexes: A New Theory on the Chemical Origin of Life Based on Evidence of Structural Symmetry [PDF]

open access: yesarXiv, 2020
The origin of life is one of the greatest mysteries. The mechanism for the synthesis of DNA is synonymous with the chemical origin of life, and theories have been developed along many lines of reasoning, but resolving all requirements remains a challenge, such as defining an objective path to produce sequences of encoded nucleotides paired as adenine ...

Dosimetric effect of silicone‐based gel on skin surface during volumetric modulated arc therapy for breast cancer

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aims to quantify and compare the dosimetric effects of varying thicknesses of StrataXRT, a silicone‐based gel, and other topical agents on the skin surface during volumetric modulated arc therapy (VMAT) for breast cancer.

Perioperative optimization of Crohn's disease

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 10-26, January 2023., 2023
Most Crohn's disease patients require surgery during the course of their illness, especially those who experience complications. The management of perioperative medications and surgery‐related decision‐making should be individualized and patient‐centered based on a multidisciplinary approach.

Mechanism of RSL3-induced ferroptotic cell death in HT22 cells: crucial role of protein disulfide isomerase

open access: yesActa Biochimica et Biophysica Sinica
Protein disulfide isomerase (PDI) was recently shown to be an upstream mediator of erastin-induced, glutathione depletion-associated ferroptosis through its catalysis of nitric oxide synthase (NOS) dimerization

CSF cytokine, chemokine and injury biomarker profile of glial fibrillary acidic protein (GFAP) autoimmunity

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Defining the CSF cytokine/chemokine and injury biomarker signature of glial fibrillary acidic protein (GFAP) autoimmunity can inform immunopathogenesis. CSF GFAP‐IgG‐positive samples (N = 98) were tested for 17 cytokines/chemokines, neurofilament light chain (NfL), and GFAP (ELLA, Bio‐Techne).

Conversion of cholesterol injected into man to cholestanol via a 3-ketonic intermediate

open access: yesJournal of Lipid Research, 1967
Cholesterol-3-3H,4-14C was injected intravenously in man and its transformation to cholestanol was studied. From the 3H:14C ratios in cholestanol isolated from blood, evidence for the participation of a ketonic intermediate in the conversion was obtained.

Protection of HT22 neuronal cells against chemically-induced ferroptosis by catechol estrogens: protein disulfide isomerase as a mechanistic target

open access: yesScientific Reports
Ferroptosis is a form of regulated cell death, characterized by excessive iron-dependent lipid peroxidation. Biochemically, ferroptosis can be selectively induced by erastin through glutathione depletion or through inhibition of glutathione peroxidase 4 ...

Profile of bile acid subspecies is similar in blood and follicular fluid of cattle

open access: yesVeterinary Medicine and Science, 2020
The composition of follicular fluid (FF) has an impact on the developmental capacity of the oocyte and the resulting embryo. FF is composed of blood plasma constituents which cross the blood follicular barrier and the secretory components of granulosa ...

Detrending career statistics in professional baseball: Accounting for the steroids era and beyond [PDF]

open access: yesEur. Phys. J. B 79, 67-78 (2011), 2010
There is a long standing debate over how to objectively compare the career achievements of professional athletes from different historical eras. Developing an objective approach will be of particular importance over the next decade as Major League Baseball (MLB) players from the "steroids era" become eligible for Hall of Fame induction. Here we address

Clinical impact and safety of brain biopsy in unexplained central nervous system disorders: a real‐world cohort study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective A substantial part of central nervous system (CNS) disorders remains unexplained, despite various new and minimally invasive diagnostic techniques. Within this rapidly developing diagnostic field, the precise role of brain biopsy is unknown.
