Heterogeneity in pure microbial systems: experimental measurements and modeling

Cellular heterogeneity influences bioprocess performance in ways that until date are not completely elucidated. In order to account for this phenomenon in the design and operation of bioprocesses, reliable analytical and mathematical descriptions are required. We present an overview of the single cell analysis, and the mathematical modeling frameworks that have potential to be used in bioprocess control and optimization, in particular for microbial processes. In order to be suitable for bioprocess monitoring, experimental methods need to be high throughput and to require relatively short processing time. One such method used successfully under dynamic conditions is flow cytometry. Population balance and individual based models are suitable modeling options, the latter one having in particular a good potential to integrate the various data collected through experimentation. This will be highly beneficial for appropriate process design and scale up as a more rigorous approach may prevent a priori unwanted performance losses. It will also help progressing synthetic biology applications to industrial scale

CEECS integration into regional production networks. Trade effects of EU-accesion

We estimate a gravity model that incorporates the extensive margin of trade and accounts for firm heterogeneity to evaluate the effect of the EU-accession on CEECs trade in intermediates and final goods for the period 1999-2009. The importance of production networks is captured by including imports of intermediates as a determinant of a country’s exports of final goods. We find a positive and significant effect of the EU-accession on CEECs trade in intermediate and final goods. Hence, the elimination of “behind the border” trade barriers has a positive impact on increasing not only trade volumes but also trade varieties.gravity equation; panel data; production networks; economic integration; trade flows.

The psychosocial impact of vaginal delivery and cesarean section in primiparous women

The aim of this study was to identify how the method of delivery and birth experience interfere with maternal psychological status early after puerperium. We conducted a prospective study on 148 women after puerperium from November 2017 to January 2018 in Bucur Maternity Hospital. Women that delivered vaginally mobilized in the first 6 hours in 73.7% of the cases, but for cesarean section after 12- 24 hours in 43.6% of the cases. Women described good support from the obstetrician in 58.1% of the cases. 90.5% of the women reported that the method of delivery did not have an impact on infant care and 73% had no lactation problems. The majority described little trauma, in 32.4% of the cases. 70.3% of the patients reported that they wanted to have more children and 59.5% of them desired the same method of delivery. Negative feelings, lactation, and taking care of the baby were not influenced in this study by the method of delivery, but by prematurity of birth and the complications that women experienced at birth

Alcoholic liver cirrhosis, more than a simple hepatic disease – A brief review of the risk factors associated with alcohol abuse

Liver cirrhosis is a significant public health problem, being an important cause of mortality and morbidity, responsible for approximately 1.8% of the total number of deaths in Europe. Chronic alcohol consumption is the most common cause of liver cirrhosis in developed countries. Europe has the highest level of alcohol consumption among all the global World Health Organisation (WHO) regions. In this paper, we briefly review major factors leading to excessive alcohol consumption in order to draw attention to the fact that alcoholic liver cirrhosis is more than a simple liver disease, and if those risk/causal factors can be prevented, the incidence of this disease could be reduced greatly. Although excessive alcohol consumption is regarded as the cause of alcoholic liver cirrhosis, the etiology is complex, involving multiple factors that act in synchrony, and which, if prevented, could greatly reduce the incidence of this disease. Children of addicts are likely to develop an alcohol-related mental disorder; however, there is no “gene for alcoholism”
