Dynamics of fungal colonization in a new medical mycology laboratory

2012

International audience; Objective of the study. - Study of the spatio-temporal fungal colonization in a new medical mycology laboratory. Methods. - A 17-month survey of airborne fungal contamination was conducted in a new medical mycology laboratory at a tertiary care university hospital. This survey was implemented at three different periods: before the new premises were occupied (period A), during the move into the new laboratory (period B) and after resumption of the mycological activities in these new premises (period C). Results. - During period A, the airborne fungal load ranged from 2.3 to 6 cfu/m(3). The most frequently recovered airborne fungi were Penicillium spp. (75 to 100%). Du…

GABAA agonista muscimola ietekme uz žurku atmiņu alcheimera slimības tipa modelī

2015

Darba mērķis bija noskaidrot GABAA agonista muscimola mazo devu ietekmi uz žurku atmiņu icv STZ AD tipa modelī. Lai noteiktu žurku iemācīšanos un atmiņu, tika veikti ūdens labirinta treniņtesti un fināla tests. Rezultāti rāda, ka icv STZ ievade žurkām izraisīja telpiskās atmiņas traucējumus. Muscimols abās devās (0,01 un 0,05 mg/kg) aizsargāja žurkas no STZ izraisītiem efektiem ūdens labirinta testā, uzlabojot to telpisko atmiņu, iemācīšanos un lokomotoro aktivitāti. Iegūtie dati ļauj secināt, ka muscimola mazo devu potenciāls ir intriģējošs jauno anti-AD terapiju izpētē un, ka būtu nepieciešama muscimola hronisko efektu izpēte minētajā modelī.

The Division of Labour Within Households: Men’s Increased Participation?

2018

Unequal division of domestic labor has been seen as a one of the most commonly documented feature on gender inequality in the western countries. The relevance of studying the division of labour in the household has actualized as female participation rates in paid labour have increased and changes in employment systems have taken place. Division of labor refers to the amount and share of time men and women spend in paid and unpaid work. Unpaid work includes domestic chores such as cleaning, repairs, preparing meals, but also caring for children. Unpaid work is usually divided in three subgroups: core household tasks i.e. housework, repairs and household upkeep and child care. Paid and unpaid…

p63 Isoforms Regulate Metabolism of Cancer Stem Cells

2014

p63 is an important regulator of epithelial development expressed in different variants containing (TA) or lacking (ΔN) the N-terminal transactivation domain. The different isoforms regulate stem-cell renewal and differentiation as well as cell senescence. Several studies indicate that p63 isoforms also play a role in cancer development; however, very little is known about the role played by p63 in regulating the cancer stem phenotype. Here we investigate the cellular signals regulated by TAp63 and ΔNp63 in a model of epithelial cancer stem cells. To this end, we used colon cancer stem cells, overexpressing either TAp63 or ΔNp63 isoforms, to carry out a proteomic study by chemical-labeling …

Membrane potential dye imaging of ventromedial hypothalamus neurons from adult mice to study glucose sensing

2013

Studies of neuronal activity are often performed using neurons from rodents less than 2 months of age due to the technical difficulties associated with increasing connective tissue and decreased neuronal viability that occur with age. Here, we describe a methodology for the dissociation of healthy hypothalamic neurons from adult-aged mice. The ability to study neurons from adult-aged mice allows the use of disease models that manifest at a later age and might be more developmentally accurate for certain studies. Fluorescence imaging of dissociated neurons can be used to study the activity of a population of neurons, as opposed to using electrophysiology to study a single neuron. This is par…

Violación de la prohibición de discriminación en el tratamiento de la prostitución por parte de los tribunales laborales españoles

2020

El reconocimiento pleno de derechos laborales a toda manifestación del trabajo sexual, incluida la prostitución, resulta plenamente necesario para la tutela no discriminatoria de las personas que, por necesidades económicas, decida ejercer libremente la prostitución. Los tribunales laborales españoles no responden, en este punto, a la lógica tuitiva del derecho del trabajo e ignoran la vulnerabilidad a la que dejan expuesta a las trabajadoras sexuales. Aplican para ello criterios que no siempre son estrictamente jurídicos, efectuando conclusiones voluntaristas que predeterminan el contenido de sus fallos sin tomar en consideración el derecho. Se produce como consecuencia de ello una discrim…

Evaluation of the cytotoxic effects of MEIC chemicals 31-50 on primary culture of rat hepatocytes and hepatic and non-hepatic cell lines

1997

The cytotoxicities of 20 chemicals (numbers 31–50) from the Multicenter Evaluation of In Vitro Cytotoxicity (MEIC) programme were assessed with a primary culture of rat hepatocytes and with two hepatic cell lines (Hep G2 and FaO) and one non-hepatic cell line (3T3). The cytotoxicities of the chemicals were evaluated by using the MTT test after the cells had been exposed to the chemicals for 24 hours. For a better evaluation of results, dose–response curves were mathematically linearised and cytotoxicity was expressed as IC50 values and IC10 values (the concentration causing 50% and 10% loss of cell viability, respectively). We found that all the compounds showed similar acute basal cytotox…

Growth rates of F0 and F1 larval and juvenile European seabass Dicentrarchus labrax in resonse to ocean acidification and warming

2022

Ongoing climate change is leading to warmer and more acidic oceans. The future distribution of fish within the oceans depends on their capacity to adapt to these new environments. Only few studies have examined the effects of ocean acidification (OA) and warming (OW) on the metabolism of long-lived fish over successive generations. We therefore aimed to investigate the effect of OA on larval and juvenile growth and metabolism on two successive generations of European sea bass (Dicentrarchus labrax L.) as well as the effect of OAW on larval and juvenile growth and metabolism of the second generation. European sea bass is a large economically important fish species with a long generation time…

Overexpression of bone morphogenetic protein-6 (BMP-6) in murine epidermis suppresses skin tumor formation by induction of apoptosis and downregulati…

2001

Bone morphogenetic protein-6 (BMP-6) is a member of the transforming growth factor-beta superfamily. In murine skin, BMP-6 is highly expressed in postmitotic keratinocytes from day 15.5 p.c. till day 6 p.p. Expression in adult skin remains at very low levels, but pathological conditions such as wounding induce the expression of BMP-6. We demonstrate that tumor promotion by TPA (12-O-tetradecanoylphorbol-13-acetate) also induces expression of BMP-6 in suprabasal keratinocytes. This induction is due to post-transcriptional regulation since the level of BMP-6 mRNA remained unchanged. We performed two-stage skin carcinogenesis experiments with transgenic mice epidermally overexpressing BMP-6. T…
