Biological warfare: the history of microbial pathogens, biotoxins and emerging threats [PDF]

Microbiology Australia, 2020
Bioterrorism is the deliberate misuse of a pathogen (virus, bacterium or other disease-causing microorganisms) or biotoxin (poisonous substance produced by an organism) to cause illness and death amongst the population.

Polychip‐A High‐Throughput Droplet Microfluidics Platform for Interrogating Microbial Interactions

Advanced Science, EarlyView.
Polychip, a fully integrated droplet microfluidics platform, enables high‐throughput, single‐cell resolution screening of polymicrobial interactions. By seamlessly combining six automated microfluidics operations on a single chip, the system accelerates antimicrobial discovery by 11 to 14 times compared to traditional robotic methods.

A Decoy‐Receptor‐Armed Biomimetic Nanotherapeutic With Inherent Tropism for Conserved Pathogenic Macrophages for Treating Osteoarthritis and Intervertebral Disc Degeneration

Advanced Science, EarlyView.
A biomimetic doppelgänger nanosystem neutralizes extracellular inflammatory cytokines and silences intracellular pyroptosis, reprogramming pathogenic macrophages to attenuate both joint and spine degeneration. ABSTRACT Osteoarthritis (OA) and intervertebral disc degeneration (IVDD) are debilitating musculoskeletal disorders driven by shared ...

Real-time analysis and classification of bioaerosols based on optical scattering properties [PDF]

Biuletyn Wojskowej Akademii Technicznej, 2017
The size and shape of biological particles are important parameters allowing discrimination between various species. We have studied several aerosols of biological origin such as pollens, bacterial spores and vegetative bacteria.

At the edge of change: Native Phragmites persistence and nonnative arrival along the dam‐regulated Colorado River

American Journal of Botany, EarlyView.
Abstract Premise The southwestern United States is at the forefront of nonnative Phragmites australis subsp. australis expansion. Native Phragmites australis subsp. americanus, likely in decline in North America, is ecologically and culturally important and of conservation interest. In the greater Grand Canyon region, the Glen Canyon Dam led to loss of

Decontamination of Chemical and Biological Warfare Agents

YAKUGAKU ZASSHI, 2009
Chemical and biological warfare agents (CBWA's) are diverse in nature; volatile acute low-molecular-weight toxic compounds, chemical warfare agents (CWA's, gaseous choking and blood agents, volatile nerve gases and blister agents, nonvolatile vomit agents and lacrymators), biological toxins (nonvolatile low-molecular-weight toxins, proteinous toxins ...

Antibody - Biological warfare agents

, 2016
An antibody (Ab), also known as immunoglobulin (Ig), is a large Y-shape protein consisting of two heavy chains and two light chains (Figure 1) which form a functionally bivalent monomer that is produced by B cells receptor used by the immune system to identify and neutralize foreign objects such as bacteria and viruses.

The musculature and skeleton of the pelvic fin of the crocodile shark, Pseudocarcharias kamoharai (Matsubara, 1936) (Elasmobranchii: Lamniformes): Morphology and sexual dimorphism

The Anatomical Record, EarlyView.
This work brings new information on the sexual characteristics of the crocodile shark (Pseudocarcharias kamoharai) exploring the pelvic fin musculature, as well as the siphon sac and the musculature and skeleton of the clasper. Our paper is the first to point out clearly the sexual dimorphism related exclusively to the pelvic fin musculature in males ...

Understanding Plant Parasitism: Hydnora Africana and European Scientific Practice in the Early Nineteenth Century**

Berichte zur Wissenschaftsgeschichte, EarlyView.
This article will analyze the uncertainties around collecting and classifying Hydnora africana in the first half of the nineteenth century. Emerging from the distinctive dryland ecologies of South Africa, Hydnora was interpreted as strange and cryptic by Europeans primarily because it is a root parasite—a complex floral trait that was little understood.
