   Sammanfattning : The general conception is that blood pressure increases with age, but that diastolic blood pressure (DBP) starts decreasing in the elderly. There are, however, indications that systolic blood pressure (SBP) might also decline in advanced age, but further studies are needed to establish whether this is true. LÄS MER

3. 7. Trace Element Analysis with Application to Environmental Pollutants Studies in Vietnam

   Författare :Thi Hong Nguyen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blood; environmental samples; discriminant analysis; ICP-MS; coal mining; hair; EDXRF; microwave digestion; CV-AAS; urine; sample preparation; coal combustion;

   Sammanfattning : In the work presented here the attention has been focused on optimising sample preparation and analytical techniques for trace element determination, analytical quality assurance and environmental applications. Trace element concentrations in various environmental matrices were investigated using Energy Dispersive X-ray Fluorescence (EDXRF), Inductively Coupled Plasma Mass Spectro-metry (ICP-MS) and Cold Vapour Atomic Absorption Spectrometry (CV-AAS).

4. 8. Blood pressure in very old age : determinants, adverse outcomes, and heterogeneity

   Författare :Bodil Weidung; Yngve Gustafson; Håkan Littbrand; Bo Carlberg; Peter Nordström; Sölve Elmståhl; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood pressure; aged 80 and over; hypertension; hypotension; mortality; stroke; gait speed; cognition disorders; dementia; cohort study;

   Sammanfattning : Background: High blood pressure (BP) is the leading risk factor for disease and mortality worldwide. However, risks associated with high BP in very old age (≥ 80 or ≥ 85 years) are not entirely understood, as the majority of scientific studies have been performed with younger populations and existing scientific knowledge about very old individuals is sometimes contradictory.

5. 9. Development and application of high-throughput methods for analysis of persistent organic pollutants in human blood

   Författare :Samira Salihovic; Bert van Bavel; Lars Lind; Myrto Petreas; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human blood; POPs; Perfluoroalkylated substances; Structural isomers; Sample preparation; Column-switch; Mass spectrometry; Kemi; Chemistry;

   Sammanfattning : The general public is continuously exposed to a wide range of environmental pollutants. This thesis focuses on a group of anthropogenic chemicals referred to as persistent organic pollutants (POPs) that have been linked to various adverse health effects in humans. LÄS MER

7. 10. Microfluidic blood sample preparation for rapid sepsis diagnostics

   Författare :Jonas Hansson; Hjalmar Brismar; Aman Russom; Fredrik Nikolajeff; KTH; []
   Nyckelord :3D fluidic networks; bacteria isolation; inertial microfluidics; lab-on-chip; microfluidics; particle filtration; PDMS membrane; selective cell lysis. sepsis;

   Sammanfattning : Sepsis, commonly referred to as blood poisoning, is a serious medical condition characterized by a whole-body inflammatory state caused by microbial infection. Rapid treatment is crucial, however, traditional culture-based diagnostics usually takes 2-5 days. LÄS MER
