Comparison of thermogenic effect of fructose and glucose in normal humans.

After nutrient ingestion there is an increase in energy expenditure that has been referred to as dietary-induced thermogenesis. In the present study we have employed indirect calorimetry to compare the increment in energy expenditure after the ingestion of 75 g of glucose or fructose in 17 healthy volunteers. During the 4 h after glucose ingestion the plasma insulin concentration increased by 33 +/- 4 microU/ml and this was associated with a significant increase in carbohydrate oxidation and decrement in lipid oxidation. Energy expenditure increased by 0.08 +/- 0.01 kcal/min. When fructose was ingested, the plasma insulin concentration increased by only 8 +/- 2 microU/ml vs. glucose. Nonetheless, the increments in carbohydrate oxidation and decrement in lipid oxidation were significantly greater than with glucose. The increment in energy expenditure was also greater with fructose. When the mean increment in plasma insulin concentration after fructose was reproduced using the insulin clamp technique, the increase in carbohydrate oxidation and decrement in lipid oxidation were markedly reduced compared with the fructose-ingestion study; energy expenditure failed to increase above basal levels. To examine the role of the adrenergic nervous system in fructose-induced thermogenesis, fructose ingestion was also performed during beta-adrenergic blockade with propranolol. The increase in energy expenditure during fructose plus propranolol was lower than with fructose ingestion alone. These results indicate that the stimulation of thermogenesis after carbohydrate ingestion is related to an augmentation of cellular metabolism and is not dependent on an increase in the plasma insulin concentration per se.(ABSTRACT TRUNCATED AT 250 WORDS)

Telomere length dynamics in normal individuals and in patients with hematopoietic stem cell-associated disorders.

The telomere length in nucleated peripheral blood (PB) cells indirectly reflects the mitotic history of their precursors: the hematopoietic stem cells (HSCs). The average length of telomeres in PB leukocytes can be measured using fluorescence in situ hybridization and flow cytometry (flow FISH). We previously used flow FISH to characterize the age-related turnover of HSCs in healthy individuals. In this review, we describe results of recent flow FISH studies in patients with selected hematopoietic stem cell-associated disorders: chronic myelogenous leukemia (CML) and several bone marrow failure syndromes. CML is characterized by a marked expansion of myeloid Philadelphia chromosome positive (Ph+) cells. Nevertheless, nonmalignant (Ph-) HSCs typically coexist in the bone marrow of CML patients. We analyzed the telomere length in > 150 peripheral blood leukocytes (PBLs) and bone marrow samples of patients with CML as well as samples of Ph- T-lymphocytes. Compared to normal controls, the overall telomere fluorescence in PBLs of patients with CML was significantly reduced. However, no telomere shortening was observed in Ph- T-lymphocytes. Patients in late chronic phase (CP) had significantly shorter telomeres than those assessed earlier in CP. Our data suggest that progressive telomere shortening is correlated with disease progression in CML. Within the group of patients with bone marrow failure syndromes, we only found significantly shortened telomeres (compared to age-adjusted controls) in granulocytes from patients with aplastic anemia (AA). Strikingly, the telomere length in granulocytes from AA patients who had recovered after immunosuppressive therapy (recAA) did not differ significantly from controls, whereas untreated patients and nonresponders with persistent severe pancytopenia (sAANR) showed marked and significant telomere shortening compared to healthy donors and patients with recAA. Furthermore, an inverse correlation between age-adjusted telomere length and peripheral blood counts was found in support of a model in which the degree of cytopenia and the amount of telomere shortening are correlated. These results support the concept of extensive proliferation of HSCs in subgroups of AA patients and suggest a potential use of telomere-length measurements as a prognostic tool in this group of disorders as well.

Building Environmental Management System for Laboratory Products Manufacturing Company according ISO 14001-standard

Tutkielman tavoitteena on rakentaa toimiva ympäristöjärjestelmä Thermo Fisher Scientific Oy:lle. Tutkimuksen tarkoituksena on myös löytää kahdelle täysin erilaiselle toiminnalle yhtenäinen ympäristöjärjestelmä, jonka avulla pystytään ottamaan huomioon molempien toimipaikkojen hieman erilaiset vaatimukset. Lisäksi tavoitteena on muodostaa ympäristöjärjestelmälle oma organisaatio, jonka avulla ympäristöjärjestelmän integrointi yrityksen prosesseihin voidaan suorittaa sujuvasti. Aluksi tutkimusongelmaa lähestytään teoreettisesta näkökulmasta,jossa tarkastellaan ympäristöjärjestelmän historiaa, rakennetta, etuja sekä ISO 14001–standardin rakennetta ja sen etenemistä ympäristöjärjestelmän rakentamisen yhteydessä aina kolmannen osapuolen sertifiointiin asti. Empiria osa alkaa alustavalla ympäristökatselmuksella, jossa selvitetään ympäristöasioiden hoidon nykytaso ja luodaan pohja koko ympäristöjärjestelmän luomiselle, jonka vankimpana perustana on ympäristöpolitiikka. Johdon hyväksymä ympäristöpolitiikka varmistaa johdon sitoutumisen järjestelmään. Ympäristöjärjestelmän toimintarakenteen muodostaminen kahdelle erilaiselle toiminnalle onnistui tutkimuksessa kiitettävästi. Se miten ympäristöjärjestelmä toimii todellisuudessa, tullaan näkemään käytännön kokemuksien yhteydessä.
