SERS detection of cell surface and intracellular components of microorganisms using nano-aggregated Ag substrate

2016

Abstract The intracellular and cell surface composition and structural features of gram-positive and gram-negative bacteria were identified using near-infrared surface-enhanced Raman scattering (SERS). The structural differences of components that reside in the cell envelope are manifested by their SERS spectra, e.g. gram-negative vs. gram-positive. Silver particles were used as a SERS substrate by exploiting the existence of strong local electromagnetic fields (hot spots) within nanoscale aggregates of the particles. The aggregation of silver nanoparticles was induced by magnesium ions. These hot spots reduce the screening length of the double layer. The obtained SERS spectra showed excell…

Does Finland Need Raciolinguistics?

2017

A growing number of applied linguists and language educators in the US/North American context advocate for and from a scholarly perspective which views language issues in relation to racial issues and vice versa. The emergent field of raciolinguistics highlights the relationships between language and race/racism and has brought about research that investigates their intersections. Should scholars in Finland adopt (and adapt) such an approach to scholarly work? Three Finland-based scholars explore this question in a question ("prompt") - response format.

Vegetation dynamics on abandoned terraces of Sicily: the course and driving forces of succession

2007

In Mediterranean Europe, terrace landscapes can be found where 1) the orography is characterized by hills or mountains, 2) there is a high amount of stone outcrops and 3) the human need for agricultural production was quite high till the recent past. During the last century, many of these landscapes have been abandoned, due to their unsuitability for mechanized, intensive agriculture and due to the general land abandonment trend which arised in large parts of Europe. Since with land abandonment start secondary succession processes, the plant and animal communities linked to agroecosystems are replaced by other species which find their habitat in the developing succession stages. This proces…

On the Choice of the Extracellular Vesicles for Therapeutic Purposes

2019

Extracellular vesicles (EVs) are lipid membrane vesicles released by all human cells and are widely recognized to be involved in many cellular processes, both in physiological and pathological conditions. They are mediators of cell-cell communication, at both paracrine and systemic levels, and therefore they are active players in cell differentiation, tissue homeostasis, and organ remodeling. Due to their ability to serve as a cargo for proteins, lipids, and nucleic acids, which often reflects the cellular source, they should be considered the future of the natural nanodelivery of bio-compounds. To date, natural nanovesicles, such as exosomes, have been shown to represent a source of diseas…

MTOR inhibitor-based combination therapies for pancreatic cancer

2018

Background: Although the mechanistic target of rapamycin (MTOR) kinase, included in the mTORC1 and mTORC2 signalling hubs, has been demonstrated to be active in a significant fraction of patients with pancreatic ductal adenocarcinoma (PDAC), the value of the kinase as a therapeutic target needs further clarification. Methods: We used Mtor floxed mice to analyse the function of the kinase in context of the pancreas at the genetic level. Using a dual-recombinase system, which is based on the flippase-FRT (Flp-FRT) and Cre-loxP recombination technologies, we generated a novel cellular model, allowing the genetic analysis of MTOR functions in tumour maintenance. Cross-species validation and pha…

Microalgae-bacteria consortia for urban wastewater treatment

2021

Los consorcios de microalgas y bacterias surgen como una opción idónea en el marco de las tecnologías sostenibles para el tratamiento de aguas residuales. Los mecanismos de eliminación de contaminantes son el resultado de interacciones ecológicas directas y/o indirectas entre las microalgas y las bacterias autóctonas de las aguas residuales. Para diseñar sistemas eficaces que incorporen consorcios de microalgas y bacterias es necesario comprender las interacciones ecológicas entre ambas comunidades dentro de los procesos de tratamiento de aguas residuales. El objetivo principal de este trabajo de investigación es, por tanto, estudiar y explorar las interacciones ecológicas para mejorar el t…

Considerations for the Analysis of Small Extracellular Vesicles in Physical Exercise

2020

Physical exercise induces acute physiological changes leading to enhanced tissue cross-talk and a liberation of extracellular vesicles (EVs) into the circulation. EVs are cell-derived membranous entities which carry bioactive material, such as proteins and RNA species, and are important mediators of cell-cell-communication. Different types of physical exercise interventions trigger the release of diverse EV subpopulations, which are hypothesized to be involved in physiological adaptation processes leading to health benefits and longevity. Large EVs (“microvesicles” and “microparticles”) are studied frequently in the context of physical exercise using straight forward flow cytometry approach…
