The Influence of Non-Uniform Cloud Cover on Transit Transmission Spectra [PDF]

open access: yes, 2015
We model the impact of non-uniform cloud cover on transit transmission spectra. Patchy clouds exist in nearly every solar system atmosphere, brown dwarfs, and transiting exoplanets. Our major findings suggest that fractional cloud coverage can exactly mimic high mean molecular weight atmospheres and vice-versa over certain wavelength regions, in ...

Molecular Weight of Melanin [PDF]

open access: bronzeNature, 1947
A METHOD of obtaining protein macro-molecules in crystalline form by the use of heparin has been described by Cohen1. As melanin is generally believed to have a high molecular weight, an attempt has been made to crystallize it by Cohen's method, using ethylene chlorhydrin as solvent.

Thermosensitive Chitosan-Containing Hydrogels: Their Formation, Properties, Antibacterial Activity, and Veterinary Usage

open access: yesGels, 2022
Mixtures of aqueous solutions of chitosan hydrochloride (CS·HCl, 1–4 wt.%) and Pluronic F-127 (Pl F-127, 25 wt.%) were studied using vibrational and rotational viscometry; the optimal aminopolysaccharide concentration (3 wt.%) and the CS·HCl:Pl F-127 ...

Efficacy and tolerability of a specific blend of amino acids in patients with anorexia nervosa treated in a hospital setting: study protocol for a randomized controlled trial

open access: yesTrials, 2023
Background Specific blends of essential amino acids (EAA) containing a high percentage of branched-chain amino acids preserves mitochondrial metabolism and higher physical resistance in elderly mice, increasing their survival and improving physical ...

Breath biomarkers of insulin resistance in pre-diabetic Hispanic adolescents with obesity

open access: yesScientific Reports, 2022
Insulin resistance (IR) affects a quarter of the world’s adult population and is a major factor in the pathogenesis of cardio-metabolic disease. In this pilot study, we implemented a non-invasive breathomics approach, combined with random forest machine ...

Do Low Molecular Weight Agents Cause More Severe Asthma than High Molecular Weight Agents? [PDF]

open access: yesPLoS ONE, 2016
INTRODUCTION:The aim of this study was to analyse whether patients with occupational asthma (OA) caused by low molecular weight (LMW) agents differed from patients with OA caused by high molecular weight (HMW) with regard to risk factors, asthma ...

Repression of the stress granule protein G3BP2 inhibits immune checkpoint molecule PD‐L1

open access: yesMolecular Oncology, EarlyView., 2022
Mounting evidence suggests that cancer stemness and immunosuppression are related, but the underlying mechanisms are not clear. We previously reported that the stress granule‐associated protein G3BP2 is involved in regulating tumor‐initiating (stem) cells.

Metabolism and signaling crosstalk in glioblastoma progression and therapy resistance

open access: yesMolecular Oncology, EarlyView., 2023
Glioblastoma is one of the most lethal human cancers with no effective treatment nowadays. Here, we review the increasing amount of evidence supporting the connection between cell signaling deregulation and metabolic reprogramming as a key event in glioblastoma resistance to cancer therapy.

Review on molecular structures of asphaltene macromolecules and instrumental analytical approaches

open access: yesShiyou shiyan dizhi, 2023
As one of the major fractions of petroleum and/or source rock extracts, asphaltene is commonly characte-rized by complicate molecular structures as well as relatively higher molecular weight (MW).

THE MOLECULAR WEIGHT OF ANTIBODIES [PDF]

open access: yesJournal of Experimental Medicine, 1937
1. Highly purified rabbit Type III pneumococcus anticarbohydrate proved to be homogeneous in the ultracentrifuge and its sedimentation constant, 7.0·10–13, did not differ from that of the principal component of normal rabbit globulin or of immune rabbit globulin containing up to 50 per cent of anti-egg albumin.
