EFFECT OF HOT AIR TREATMENT ON MINIMALLY PROCESSED CAULIFLOWER

2013

The request of minimally processed vegetable is continuously increasing, and there is a growing interest for new fresh cut products. Cauliflower, as other cabbages, is highly appreciated for its nutritional value due to the good content of vitamins, antioxidants and anti-carcinogenic compounds. It is suitable to be used as a minimally processed vegetable, but harvesting and the following processing can cause a severe stress determining the appearance of accelerated senescence symptoms. The aim of the present work was to investigate the effect of hot air treatment and cold storage on minimally processed green cauliflower. Fresh-cut cauliflower florets put in sealed PE bags were treated at 48…

Intimate male partner violence impairs immune control over herpes simplex virus type 1 in physically and psychologically abused women.

2004

OBJECTIVE: Intimate partner violence (IPV) against women is a worldwide problem and a cause of significant distress and threat to health. Studies have focused mainly on mental health, and few have considered the effect on physiological systems. The aim of this research was to determine whether IPV also compromises the immune system, as evidenced by a decrease in immune regulation over herpes simplex virus type 1 (HSV-1), the latent virus that causes cold sores. METHODS: Physically abused (N = 47) and psychologically abused women (N = 27) were compared with nonabused control women (N = 37). Information about sociodemographic characteristics, lifetime history of victimization, and mental heal…

How consistent are the transcriptome changes associated with cold acclimation in two species of the Drosophila virilis group?

2015

This work was financially support by a Marie Curie Initial Training Network grant, “Understanding the evolutionary origin of biological diversity” (ITN-2008–213780 SPECIATION), grants from the Academy of Finland to A.H. (project 132619) and M.K. (projects 268214 and 272927), a grant from NERC, UK to M.G.R. (grant NE/J020818/1), and NERC, UK PhD studentship to D.J.P. (NE/I528634/1). For many organisms the ability to cold acclimate with the onset of seasonal cold has major implications for their fitness. In insects, where this ability is widespread, the physiological changes associated with increased cold tolerance have been well studied. Despite this, little work has been done to trace chang…

A New Cold War?

Russian concept of the Eurasian Aerospace Defense System. Analysis of the problem

2018

The author of the article describes the most important theses of A. Podberezkin plan against the geopolitical Russia background which form a paradigm of a common security in Russian terms on a strategic area of Eurasia. It is of a particular significance in view of the growing threats to modern world. Especially of hazardous nature is current problem of North Korea in connection with nuclear testing carried out by unpredictable regime of Kim Jong-un which creates the risk that sudden conflict can drag the whole Peninsula into a war. This, in turn, would lead to the US intervention there. Effects of the possible conflict involving superpower are hard to predict. Another current problem is Mo…

Thermal aggregation and ion-induced cold-gelation of bovine serum albumin

2009

Protein cold-gelation has recently received particular attention for its relevance in bio and food technology. In this work, we report a study on bovine serum albumin cold-gelation induced by copper or zinc ions. Metal-induced cold-gelation of proteins requires two steps: during the first one, the heat treatment causes protein partial unfolding and aggregation; then, after cooling the solution to room temperature, gels are formed upon the addition of metal ions. The thermally induced behaviour has been mainly investigated through different techniques: Fourier transform infrared (FTIR) spectroscopy, circular dichroism, dynamic light scattering (DLS) and rheology. Data have shown that the agg…

Calcification is not the Achilles' heel of cold-water corals in an acidifying ocean

2015

Ocean acidification is thought to be a major threat to coral reefs: laboratory evidence and CO2 seep research has shown adverse effects on many coral species, although a few are resilient. There are concerns that cold-water corals are even more vulnerable as they live in areas where aragonite saturation (?ara) is lower than in the tropics and is falling rapidly due to CO2 emissions. Here, we provide laboratory evidence that net (gross calcification minus dissolution) and gross calcification rates of three common cold-water corals, Caryophyllia smithii, Dendrophyllia cornigera, and Desmophyllum dianthus, are not affected by pCO2 levels expected for 2100 (pCO2 1058 ?atm, ?ara 1.29), and nor a…

The role of Finnish leftists in Soviet-Finnish artistic exchanges during the late socialist period

2020

The article examines artistic exchanges between the USSR and Finland from the viewpoint of the Finnish left. After WWII, Finland was in a difficult geopolitical position; although not occupied by the USSR, it received little support from the West and so remained an independent capitalist democracy, with little foreign leverage. The Soviet influence was felt in many areas, and throughout the Cold War, Finland received many more world-class Soviet artists than any other Western country. This was in part a consequence of Finland’s proximity to the USSR, but the Finnish Communist Party, a major domestic political force, also played a role. Immediately after the war, organizations associated wit…

Der Einflu� von Antibiotica auf die �berlebensrate von Mikroorganismen bei tiefen Temperaturen

1959

Die Lebendkeimzahl in einer Suspension vonE. coli nimmt bei +4°C langsam zu, nimmt bei-5°C wenig ab und fallt bei-19°C innerhalb von 24 Std stark, wahrend die Verringerung in den folgenden Tagen nur noch gering ist. Streptomycin und Penicillin vermindern in allen 3 Temperaturbereichen die Keimkonzentration in Abhangigkeit von der Antibioticumkonzentration. Subbakteriostatische Konzentrationen von Streptomycin haben bei-19°C eine zusatzliche Wirkung. Die Resistenz der in uberbakteriostatischen Antibioticakonzentrationen bei diesen Temperaturen uberlebenden Keime ist gegenuber dem Ausgangsstamm weder erhoht noch vermindert.
