The radiation stability of glycine in solid CO2 - in situ laboratory measurements with applications to Mars [PDF]

2015, Icarus 252, 466-472, 2015
The detection of biologically important, organic molecules on Mars is an important goal that may soon be reached. However, the current small number of organic detections at the Martian surface may be due to the harsh UV and radiation conditions there.

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

Advanced Sustainable Systems, EarlyView.
Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...

CPL‐Diff: A Diffusion Model for De Novo Design of Functional Peptide Sequences with Fixed Length

Advanced Science, EarlyView.
This study presents a diffusion model for generating functional peptide sequence lengths using mask control. The model can generate antimicrobial, antifungal, and antiviral peptides with specific lengths on demand. The model learns the structure of peptides better and generates peptides with better physicochemical properties, and the model has good ...

Detection of simplest amino acid glycine in the atmosphere of Venus [PDF]

arXiv, 2020
Amino acids are considered to be prime ingredients in chemistry, leading to life. Glycine is the simplest amino acid and most commonly found in animal proteins. It is a glucogenic and non-essential amino acid that is produced naturally by living bodies and plays a key role in the creation of several other important bio-compounds and proteins. We report

Inhibiting the Histone Demethylase Kdm4a Restrains Cardiac Fibrosis After Myocardial Infarction by Promoting Autophagy in Premature Senescent Fibroblasts

Advanced Science, EarlyView.
Kdm4a downregulation restrains excessive cardiac interstitial fibrosis and remodeling by depressing the premature senescence of fibroblasts in the advanced stage after MI but does not affect early ventricular rupture. It verified that Kdm4a downregulation promotes autophagy in premature senescent fibroblasts by increasing the H3K9m3 modification of the

Explainable Deep Multilevel Attention Learning for Predicting Protein Carbonylation Sites

Advanced Science, EarlyView.
Selective carbonylation sites (SCANS) are conceptualized, designed, evaluated, and released. SCANS captures segment‐level, protein‐level, and residue embeddings features. It utilizes elaborate loss function to penalize cross‐predictions at the residue level.

Sustainability‐Inspired Upcycling of Organophosphorus Pollutants into Phosphatic Fertilizer in a Continuous‐Flow Reactor

Angewandte Chemie, EarlyView.
First report of organophosphorus pollutants selective degradation, via the synergistic effect of peroxymonosulfate and sodium percarbonate, into phosphates that are continually converted into phosphatic fertilizer by struvite precipitation on a continuous‐flow reactor. Abstract With the increasing requirement for phosphorus resources and their shortage
