Effect of daily light integral treatments on free amino acids and sugars contributing flavor and acrylamide formation in potato tubers of Solanum tuberosum L.

To study the effect of photoperiodic conditions on the chemical composition of potato tubers, seven cultivars, grown under controlled conditions, were evaluated for the content of free amino acids (FAA) and sugars. The differences in these compounds may have an effect on the susceptibility of acrylamide formation during potato processing as well as on the flavor profile of potato products. Tubers were produced in growth chambers under two artificially induced photoperiods; 8 h light and 15 h light per day, resulting in conditions with two different daily light integral (DLI) levels. The photoperiodic treatments influenced the total FAA and free sugar contents and composition. Of the analyzed 19 FAAs, the concentrations of 14 FAAs were significantly lower in tubers exposed to the 15 h light period compared to 8 h light, whereas the glucose content was significantly higher. The total FAA concentrations were 15–46% lower and the glucose concentrations 6–64% higher in the seven cultivars exposed to the 15 h light conditions than in those grown in 8 h light

Koronan vaikutukset vapaa-ajan palveluiden ja tilojen käyttöön

Tutkimushankkeessa selvitettiin Covid 19-pandemian vaikutuksia vapaa-ajanpalveluiden tuotantoon ja käyttöön, sekä palveluiden tulevaisuudennäkymiä ja haasteita pandemian jälkeen. Tutkimusmenetelminä käytettiin haastatteluita, kyselytutkimusta (otos 4400) sekä työpajoja. Raportissa esitetään hankkeen tulokset.</p

Vapaa-ajan palveluiden digitalisoituminen avaa uusia mahdollisuuksia, mutta ei korvaa kokemuksia paikan päällä.

Koronapandemia on vauhdittanut kaupunkien vapaa-ajan palveluiden digitalisoitumista. Digipalveluiden käyttö ja kiinnostus niitä kohtaan ovat lisääntyneet, mutta digimuoto on myös karsinut käyttäjiä. Kaupunkilaiset odottavat innokkaasti kirjastojen, konserttien, teattereiden ja liikuntapaikkojen avautumista. He myös aikovat palata niiden käyttäjiksi entiseen tapaan.</p

Epidemiological and treatment-related factors contribute to improved outcome of oropharyngeal squamous cell carcinoma in Finland

Background: Treatment for oropharyngeal squamous cell carcinoma (OPSCC) has changed, as the proportion of human papilloma virus (HPV)-related disease has increased. We evaluated nationwide information on its management and outcome during the treatment paradigm change period.Methods: We included all patients diagnosed and treated for OPSCC at the five Finnish university hospitals from 2000 to 2009. Patient records and pathology registries provided the clinicopathological data. p16 staining was performed on primary tumor samples of patients who had received treatment with curative intent.Results: A total of 674 patients were diagnosed and treated for OPSCC and the incidence increased along the study period. Of the evaluable tumors 58.5% were p16-positive and the number of p16-positive tumors increased along the years. The treatment was given with curative intent for 600 patients and it was completed in 564. Of them, 47.9% underwent primary surgery and 52.1% received definitive oncological treatment. Also, the treatment protocol changed towards a more oncological approach. Among patients treated with curative intent the five-year overall, disease-specific and disease-free survival rates were 60.1, 71.5 and 57.0%. In multivariate analysis, p16-positivity seemed to relate to reduced disease mortality in lateral and anterior-wall disease. Depending on primary tumor localization, also sex, classes T3-4, presence of regional metastasis and radiotherapy modality had an association with disease mortality.Conclusion: The incidence of p16-positive OPSCC and delivery of definitive oncological treatment increased in Finland during the study period. An improved survival outcome compared with the previous nationwide investigation was observed in this subset of patients.Peer reviewe

Real-time monitoring shows substantial excess all-cause mortality during second wave of COVID-19 in Europe, October to December 2020.

The European monitoring of excess mortality for public health action (EuroMOMO) network monitors weekly excess all-cause mortality in 27 European countries or subnational areas. During the first wave of the coronavirus disease (COVID-19) pandemic in Europe in spring 2020, several countries experienced extraordinarily high levels of excess mortality. Europe is currently seeing another upsurge in COVID-19 cases, and EuroMOMO is again witnessing a substantial excess all-cause mortality attributable to COVID-19.Funding statement: The EuroMOMO network hub at Statens Serum Institut receives funding from European Centre for Disease Prevention and Control, Solna, Sweden, through a framework contract 2017-2020.S
