Purification and characterisation of the bacteriocin produced by Lactobacillus plantarum, isolated from Chinese pickle

open access: yesCzech Journal of Food Sciences, 2014
119 strains of lactic acid bacteria from Chinese pickle were tested for production of antimicrobial compounds (bacteriocins). Among them, strain C8 showed strongly antibacterial activity against Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC ...

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

open access: yesAdvanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin

open access: yesAngewandte Chemie, EarlyView.
We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...

RT‐DETR‐DA for Complex Scenes: Distracted Driving Detection With Feature Interaction and Dynamic Perception

open access: yesAdvanced Intelligent Systems, EarlyView.
This work proposes RT‐DETR‐DA, an enhanced real‐time detection framework for identifying distracted driving in complex, real‐world environments. The model introduces a dynamic sparse gating multiscale attention module and an attention‐guided dual‐path fusion module to strengthen multiscale perception and cross‐layer feature interaction.

Programming Palladium Cage Geometry through Ligand Redox Modulation

open access: yesAngewandte Chemie, EarlyView.
A neutral redox‐active exTTF ligand (L) forms a Pd2L4 cage, whereas its oxidized form (Lox) yields a Pd2(Lox)2 macrocycle. Lox further assembles with a dibenzothiophene derivative (L′) into Pd2(Lox)(L′)2 and Pd4(Lox)4(L′)4 architectures. Reduction of Pd2(Lox)2 and Pd2(Lox)(L′)2 restores the parent Pd2L4 cage, enabling redox controlled nuclearity ...

What if Newton’s Gravitational Constant Was Negative?

open access: yesGalaxies, 2019
In this work, we seek a cosmological mechanism that may define the sign of the effective gravitational coupling constant, G. To this end, we consider general scalar-tensor gravity theories as they provide the field theory natural framework for the ...

Modification of C60 nano-interlayers on organic field-effect transistors based on 2,7-diocty[1]benzothieno-[3,2-b]benzothiophene (C8-BTBT)/SiO2

open access: yesResults in Physics, 2020
The modification of C60 nano-interlayers on the organic field-effect transistors (OFETs) based on 2,7-diocty[1]benzothieno-[3,2-b]benzothiophene (C8-BTBT)/SiO2 was addressed at both the electronic structure and device level.

A higher-order Skyrme model

open access: yes, 2017
We propose a higher-order Skyrme model with derivative terms of eighth, tenth and twelfth order. Our construction yields simple and easy-to-interpret higher-order Lagrangians.

Diagnostic Odyssey of Atypical Long‐Chain 3‐Hydroxyacyl‐CoA Dehydrogenase Deficiency (LCHADD) Explained by Three Allelic Products From Two Pathogenic Variants

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Long‐chain 3‐hydroxyacyl‐CoA dehydrogenase deficiency (LCHADD) is an autosomal recessive mitochondrial defect of long‐chain fatty acid β‐oxidation, caused by biallelic pathogenic variants in HADHA or HADHB. We report a 22‐year‐old male with an atypically mild presentation of LCHADD who was referred to the Undiagnosed Diseases Network (UDN ...
