Digital Image Analysis of Actinomycetes Colonies as a Potential Aid for Rapid Taxonomic Identification [PDF]

open access: yes, 2010
High frequency isolation of actinomycetes poses a challenge for the taxonomists hence simple and rapid identification methods are required. Our work to catalogue biodiversity of actinomycetes of Goa yielded several distinct morphotypes.

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

Nonmulberry Silk Fibroin Doping Boosts Charge Transfer and Charge Injection in Aligned Polypyrrole‐Silk Scaffolds for Low‐Voltage Neurostimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Conductive silk‐polypyrrole scaffolds couple redox stability with cell‐affinitive peptides present innately in an endogenous silk fibroin, enabling optimized electrical stimulation to drive neurite outgrowth. Findings establish electrochemical‐biological link for biomaterial design rules for smart nerve guidance conduits that can provide low voltage ...

ANTAGONIST ACTIVITY OF Streptomyces sp. Y20 AGAINST FUNGI CAUSING DISEASES IN PLANTS AND FRUITS

open access: yesTropical and Subtropical Agroecosystems, 2022
Background: Crop microbial pathogens reduce the production and quality of agricultural products. They cause substantial increase costs for producers of fruits, vegetables, and ornamental plants with negative consequences on economy and food security at ...

The Jackprot Simulation Couples Mutation Rate with Natural Selection to Illustrate How Protein Evolution Is Not Random [PDF]

open access: yes, 2011
Protein evolution is not a random process. Views which attribute randomness to molecular change, deleterious nature to single-gene mutations, insufficient geological time, or population size for molecular improvements to occur, or invoke “design ...

Reclassification of Streptomyces castelarensis and Streptomyces sporoclivatus as later heterotypic synonyms of Streptomyces antimycoticus

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2020
We investigated the taxonomic relationship between Streptomyces antimycoticus , Streptomyces castelarensis, Streptomyces sporoclivatus, and Streptomyces violaceusniger .

Reclassification of Streptomyces hygroscopicus strains as Streptomyces aldersoniae sp. nov., Streptomyces angustmyceticus sp. nov., comb. nov., Streptomyces ascomycinicus sp. nov., Streptomyces decoyicus sp. nov., comb. nov., Streptomyces milbemycinicus sp. nov. and Streptomyces wellingtoniae sp. nov. [PDF]

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2010
A polyphasic study was undertaken to determine the taxonomic status of six strains received asStreptomyces hygroscopicus. The strains had chemotaxonomic and morphological properties typical of members of the genusStreptomycesand formed distinct phyletic lines in theStreptomyces16S rRNA gene tree.

Gut Bacteria Improve Depressive Symptoms by Degrading Cortisol into Androgen

open access: yesAdvanced Science, EarlyView.
Chronic stress is an important risk factor for stress‐related disorders such as depression. Stress hormone cortisol is essential for the pathogenesis of stress‐related disorders such as depression. Some gut microbiota degraded cortisol, and improve depressive symptoms.

NsrR from Streptomyces coelicolor is a nitric oxide-sensing [4Fe-4S] cluster protein with a specialized regulatory function [PDF]

open access: yes, 2015
The Rrf2 family transcription factor NsrR controls expression of genes in a wide range of bacteria in response to nitric oxide (NO). The precise form of the NO-sensing module of NsrR is the subject of controversy because NsrR proteins containing either ...

Enzymatic Remodelling of Tumour Microenvironment Enhances Anti‐CEACAM5 CAR T‐Cell Efficacy Against Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
This study shows anti‐CEACAM5 CAR T‐cells are ineffective against colorectal cancer (CRC) because of CEACAM5 sequestration at intercellular junctions and the thick tumour cell glycocalyx. Enzymatic treatments of CRC cell monolayer/tissue section with trypsin or hyaluronidase restore CEACAM5 availability, enhance CAR T‐cell activation, increase ...
