  2. 11. Body Protein and its Change in Patients During Anti-Tumor Treatment

    Author : Lianna Kadar; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytology; Gastrointestinal tumors; Breast cancer; Lung cancer; Prognosis; Body protein; oncology; cancerology; Cytologi; onkologi; cancer;

    Abstract : The purpose of this study was to investigate how total body protein and its fraction of body weight (body protein fraction) change in cancer patients during different anti-tumor treatments, and to see if these changes have any clinical significance in the form of prognostic value or correlation with disease course and tumor response. In 84 patients, 28 with lung cancer, 24 with gastrointestinal tumors, 30 with breast cancer, 1 with non-Hodgkin lymphoma and 1 with kidney cancer, the total amount of body nitrogen was measured using an in vivo prompt gamma neutron activation technique.

  4. 12. Phosphorus removal in reactive filter materials : factors affecting the sorption capacity

    Author : Charlotte Nilsson; Gunno Renman; Lena Johansson Westholm; Aleksandra Drizo; Annelie Hedström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Phosphorus is an essential component in all living organisms; it is one of the components of the DNA and the key element in the energy supplying molecule adenosine triphosphate (ATP). Throughout the history, humans have been recycling phosphorus to agriculture; thereby increasing the yield, examples of this includes the burning of plants and the use of manure. READ MORE

  5. 13. Fish bile in environmental analysis

    Author : Margaretha Adolfsson-Erici; Michael McLachlan; Lillemor Asplund; Freek Ariese; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fish bile estrogenic triclosan rubber additives pulp and paper; Environmental chemistry; Miljökemi;

    Abstract : This work explores the usefulness of fish bile analysis in combination with biomarkers for identifying and evaluating new environmental contaminants in the aquatic environment. It illustrates how bile analysis can be used together with biomarkers to assess the causes of estrogenic effects, to identify chemicals in the aquatic environment that are taken up by fish, and to monitor environmental exposure.

  6. 14. Source, occurrence, and fate of pharmaceuticals in natural waters

    Author : Atlasi Daneshvar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The consumption of pharmaceuticals has increased in the last few decades. After usage, pharmaceuticals are excreted via urine and feces and transported to wastewater treatment plants (WWTPs) where they are subjected to treatment processes, and finally discharged into rivers.

  7. 15. Managing Eutrophic Waters in Artificial Recharge Plants : Cyanotoxin risk in Swedish freshwaters

    Author : Jing Li; Avdelningen för Teknisk vattenresurslära; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drinking water; cyanobacterial blooms; cyanotoxins; nutrients; total phosphorus; DIN TP; quick test kit;

    Abstract : In the last decades, the frequency and intensity of cyanobacterial blooms have been of increasing concern. They have become a direct threat to the drinking water supply by clogging filters, bringing odour and unpleasant taste to the treated water and worst of all, causing elevated cyanotoxins, which can be difficult to remove, yet lead to severe health issues.
