Abstract
Using the fusion-evaporation reaction ^{96}Ru(^{58}Ni,p4n)^{149}Lu and the MARA vacuum-mode recoil separator, a new proton-emitting isotope ^{149}Lu has been identified. The measured decay Q value of 1920(20) keV is the highest measured for a ground-state proton decay, and it naturally leads to the shortest directly measured half-life of 450_{-100}^{+170} ns for a ground-state proton emitter. The decay rate is consistent with l_{p}=5 emission, suggesting a dominant πh_{11/2} component for the wave function of the proton-emitting state. Through nonadiabatic quasiparticle calculations it was concluded that ^{149}Lu is the most oblate deformed proton emitter observed to date.

Abstract
In two recent papers by Pore et al. and Khuyagbaatar et al., discovery of the new isotope ^{244}Md was reported. The decay data, however, are conflicting. While Pore et al. report two isomeric states decaying by α emission with E_{α}(1)=8.66(2) MeV, T_{1/2}(1)=0.4_{-0.1}^{+0.4} s and E_{α}(2)=8.31(2) MeV, T_{1/2}(2)≈6 s, Khuyagbaatar et al. [Phys. Rev. Lett. 125, 142504 (2020).PRLTAO0031-900710.1103/PhysRevLett.125.142504] report only a single transition with a broad energy distribution of E_{α}=(8.73-8.86) MeV and T_{1/2}=0.30_{-0.09}^{+0.19} s. The data published in Pore et al. are very similar to those published for ^{245m}Md [E_{α}=8.64(2), 8.68(2) MeV, T_{1/2}=0.35_{-0.16}^{+0.23} s [V. Ninov, F. P. Heßberger, S. Hofmann, H. Folger, G. Münzenberg, P. Armbruster, A. V. Yeremin, A. G. Popeko, M. Leino, and S. Saro, Z. Phys. A 356, 11 (1996).ZPAHEX0939-792210.1007/s002180050141] ]. Therefore, we compare the data presented for ^{244}Md in Pore et al. with those reported for ^{245}Md in Ninov et al. and also in Khuyagbaatar et al. We conclude that the data presented in Pore et al. shall be attributed to ^{245}Md with small contributions (one event each) from ^{245}Fm and probably ^{246}Md.

Abstract
BACKGROUND Allergen-specific immunotherapy balances the Th2-biased immunity towards Th1 and Treg responses. Adjuvants are used in allergen preparations to intensify the immune responses. The increased prevalence of allergies in developed societies has been associated with decreased microbial load during childhood. This has initiated a search for microbial structures to be used as adjuvants. Our study has shown that a synthetic triacedimannose (TADM) may suppress the Th2-type allergic inflammatory response. The aim of this study was to compare the properties of TADM with capacities of other adjuvants, CpG ODN and MPL, to modulate cytokine production in PBMC and regulate sensitisation in an OVA-sensitised mouse asthma model. METHODS The effects of TADM were studied in vitro on birch stimulated PBMC cultures of birch allergic rhinitis patients with other known adjuvants. Cytokines in supernatants were measured by Luminex. Effects of TADM were analysed in vivo in a mouse model of OVA-induced allergic asthma by analysing BAL, cytokine mRNA and serum antibodies. RESULTS TADM was the only adjuvant that significantly suppressed the production of all birch induced Th2-type cytokines. In a murine model, TADM significantly suppressed the specific IgE production and enhanced IFN-γ production. CONCLUSIONS TADM suppresses the birch allergen induced Th2-type cytokine responses in allergic subjects more efficiently than the two other adjuvants, MPL and CpG ODN. TADM is immunomodulatory also in vivo and decreases the IgE levels and increases the IFN-γ responses in a murine model. These results suggest that TADM may be a promising candidate for novel adjuvants in immunotherapy.

Abstract
OBJECTIVES The aims of this study were to determine the within-patient variation in the duration of morning stiffness (MS) over 1 year and the corresponding monetary equivalents assigned to its changes using the willingness-to-pay (WTP) methodology. METHOD A sample of 100 patients with rheumatoid arthritis (RA) was drawn from the register of the Hospital District of Southwest Finland. Subjects were interviewed by telephone on recruitment and 1 year later, using the same structured questionnaire. The subjects were asked to estimate in minutes the typical duration of their MS during the previous week. Sociodemographic background data and subjects' WTP for a 25, 50, 75, and 100% reduction in MS duration were requested, and years with RA diagnosis and serological data were obtained from hospital records. RESULTS After 1 year, there was a reduction in average MS duration from 44.7 min to 39.0 min (ns); duration was reduced in 35% of patients, unchanged in 35%, and prolonged in 30%. Changes in MS duration were reflected by within-patient variation in WTP estimates. In linear regression models, change in duration of MS significantly (p < 0.03) explained the variation in change of WTP for symptom reduction. CONCLUSIONS WTP methodology produces consistent monetary values to assess the relative values patients with RA place on reduction in duration of MS.

Abstract
INTRODUCTION Psoriasis results in expenses to patients from many cost sources. Psoriasis treatments may result in considerable time and traveling costs, yet many studies fail to account for these costs. The objective of this study was to evaluate the multidimensional economic burden of psoriasis to patients. METHODS The study was based on 232 Finnish patients with psoriasis or psoriatic arthritis visiting a tertiary level dermatological clinic during a 1-year study period between October 1, 2009 and September 30, 2010. The data were based on a patient questionnaire, clinical data from the medical records and reimbursement data from the Finnish Social Insurance Institution. Item costs were based on true costs charged from the patients and all time cost estimates were based on the Human Capital Approach method. RESULTS 199 patients with psoriasis and 33 with psoriatic arthritis were included in the study. Total costs were higher for patients receiving traditional systemic medications or phototherapy than those not receiving such treatment. Travel costs and travel time costs accounted for more than 60% of the costs of phototherapy. Skin care at home was time consuming and thus caused significant burden to patients. The majority of the visit costs arose from hospital visits and only a small proportion were attributed to visiting primary health care providers. CONCLUSION Visit charges and other patient co-payments were estimated to play a minor role in the total cost of psoriasis incurred by patients, while travel costs and lost time comprised the majority of the costs, which should not be omitted in future studies regarding costs of treatments.

Abstract
A multiparticle spin-trap isomer has been discovered in the proton-unbound nucleus (73)(158)Ta85 . The isomer mainly decays by γ-ray emission with a half-life of 6.1(1) μs. Analysis of the γ-ray data shows that the isomer lies 2668 keV above the known 9+ state and has a spin 10ℏ higher and negative parity. This 19- isomer also has an 8644(11) keV, 1.4(2)% α-decay branch that populates the 9+ state in (154)Lu. No proton-decay branch from the isomer was identified, despite the isomer being unbound to proton emission by 3261(14) keV. This remarkable stability against proton emission is compared with theoretical predictions, and the implications for the extent of observable nuclides are considered.

Abstract
The rotational band structure of the Z=104 nucleus (256)Rf has been observed up to a tentative spin of 20ℏ using state-of-the-art γ-ray spectroscopic techniques. This represents the first such measurement in a superheavy nucleus whose stability is entirely derived from the shell-correction energy. The observed rotational properties are compared to those of neighboring nuclei and it is shown that the kinematic and dynamic moments of inertia are sensitive to the underlying single-particle shell structure and the specific location of high-j orbitals. The moments of inertia therefore provide a sensitive test of shell structure and pairing in superheavy nuclei which is essential to ensure the validity of contemporary nuclear models in this mass region. The data obtained show that there is no deformed shell gap at Z=104, which is predicted in a number of current self-consistent mean-field models.

Abstract
The rotational band structure of 255Lr has been investigated using advanced in-beam gamma-ray spectroscopic techniques. To date, 255Lr is the heaviest nucleus to be studied in this manner. One rotational band has been unambiguously observed and strong evidence for a second rotational structure was found. The structures are tentatively assigned to be based on the 1/2-[521] and 7/2-[514] Nilsson states, consistent with assignments from recently obtained alpha decay data. The experimental rotational band dynamic moment of inertia is used to test self-consistent mean-field calculations using the Skyrme SLy4 interaction and a density-dependent pairing force.

Abstract
Thirty-three patients were treated with disodium cromoglycate (DSCG). Of these 5 had vernal conjunctivitis, 18 had allergic conjunctivitis and 10 had mild chronic conjunctivitis in which the exact aetiology could not be determined. 70% of patients with DSCG as the only medication achieved at least some beneficial effect being almost exclusively in the groups of either vernal or allergic conjunctivitis. The basic trend seemed to indicate a reduction in severity during the treatment with DSCG in allergic diseases.

Gamma-ray transitions have been identified for the first time in the extremely neutron-deficient (N=Z+2) nucleus (110)Xe, and the energies of the three lowest excited states in the ground-state band have been deduced. The results establish a breaking of the normal trend of increasing first excited 2(+) and 4(+) level energies as a function of the decreasing neutron number as the N=50 major shell gap is approached for the neutron-deficient Xe isotopes. This unusual feature is suggested to be an effect of enhanced collectivity, possibly arising from isoscalar n-p interactions becoming increasingly important close to the N=Z line.

Abstract
A rotational band has been unambiguously observed in an odd-proton transfermium nucleus for the first time. An in-beam gamma-ray spectroscopic study of 101/251Md has been performed using the gamma-ray array JUROGAM combined with the gas-filled separator RITU and the focal plane device GREAT. The experimental results, compared to Hartree-Fock-Bogolyubov calculations, lead to the interpretation that the rotational band is built on the [521]1/2(-) Nilsson state.

Abstract
Lifetimes of prolate intruder states in 186Pb and oblate intruder states in 194Po have been determined by employing, for the first time, the recoil-decay tagging technique in recoil distance Doppler-shift lifetime measurements. In addition, lifetime measurements of prolate states in 188Pb up to the 8+ state were carried out using the recoil-gating method. The B(E2) values have been deduced from which deformation parameters |beta2|=0.29(5) and |beta2|=0.17(3) for the prolate and the oblate bands, respectively, have been extracted. The results also shed new light on the mixing between different shapes.

Abstract
A long-standing prediction of nuclear models is the emergence of a region of long-lived, or even stable, superheavy elements beyond the actinides. These nuclei owe their enhanced stability to closed shells in the structure of both protons and neutrons. However, theoretical approaches to date do not yield consistent predictions of the precise limits of the 'island of stability'; experimental studies are therefore crucial. The bulk of experimental effort so far has been focused on the direct creation of superheavy elements in heavy ion fusion reactions, leading to the production of elements up to proton number Z = 118 (refs 4, 5). Recently, it has become possible to make detailed spectroscopic studies of nuclei beyond fermium (Z = 100), with the aim of understanding the underlying single-particle structure of superheavy elements. Here we report such a study of the nobelium isotope 254No, with 102 protons and 152 neutrons--the heaviest nucleus studied in this manner to date. We find three excited structures, two of which are isomeric (metastable). One of these structures is firmly assigned to a two-proton excitation. These states are highly significant as their location is sensitive to single-particle levels above the gap in shell energies predicted at Z = 114, and thus provide a microscopic benchmark for nuclear models of the superheavy elements.

Abstract
BACKGROUND The characteristic feature of chronic rhinosinusitis with nasal polyposis (CRSwNP) is eosinophilic inflammation of the sinus mucosa; a type of inflammation also seen in asthmatic airways. Similar histopathologic findings of airway remodelling are present in both diseases. Remodelling is tightly controlled by matrix metalloproteinases (MMP). Increase of collagenase-2 (MMP-8) expression in the bronchial epithelial cells has been described in asthmatic patients, but it has not been studied in CRSwNP. METHODS The concentrations and degree of activation of MMP-8 were analysed by immunofluorometric assay and Western blotting, respectively, in sinus mucus samples from CRSwNP patients and in nasal lavages from healthy controls in relation to inductive cytokines interleukin-8 (IL-8) and tumour necrosis factor-alpha (TNF-alpha). RESULTS Significantly elevated levels of MMP-8 and IL-8 but not TNF-alpha were found in CRSwNP patients relative to controls. In particular, the activation of mesenchymal-type MMP-8 but not polymorphonuclear-type MMP-8 was associated with elevated IL-8 levels. CONCLUSIONS The IL-8 and MMP-8 seemingly form an inductive cytokine-proteinase cascade in CRSwNP pathogenesis. Together they provide a target for novel therapies and a diagnostic tool for monitoring CRSwNP treatment.

Abstract
OBJECTIVE To examine the association of childhood socioeconomic position (SEP) with adult cardiovascular risk factors, vascular structure, and vascular function in a contemporary population of young adults. DESIGN Population based prospective cohort study with baseline assessment in 1980. SETTING Finland. PARTICIPANTS 856 men and 1066 women whose childhood SEP was determined by parental occupational status (manual, lower non-manual, upper non-manual) at age 3-18 years. MAIN OUTCOME MEASURES Cardiovascular risk factors, carotid artery intima-media thickness, and brachial artery flow mediated vasodilatation, assessed at age 24-39 years. RESULTS After adjustment for age and adult SEP, systolic pressure was 2.3 mm Hg higher (p = 0.0002), high density lipoprotein (HDL) cholesterol 0.03 mmol/l lower (p = 0.02), and insulin resistance score (homeostasis model assessment index) 0.12 units greater (p = 0.05) among men; and systolic pressure was 1.3 mm Hg higher (p = 0.02), diastolic pressure 1.1 mm Hg higher (p = 0.01), and height 1.1 cm lower (p < 0.0001) among women for each step down the childhood SEP hierarchy. Lower childhood SEP was associated with a 20% increase in the odds of having a waist circumference > 102 cm in men and > 88 cm in women (overall p = 0.05). Childhood SEP was not associated with intima-media thickness, flow mediated vasodilatation, the metabolic syndrome, low density lipoprotein cholesterol, triglycerides, body mass index, alcohol consumption, or smoking. CONCLUSIONS Among adults under 40, low childhood SEP predicted higher blood pressure and central obesity and, among men, unfavourable HDL cholesterol and insulin resistance, independent of current SEP. No independent effects were found on adult vascular structure, vascular function, or health related behaviours at this life stage.

Abstract
In-beam gamma-ray spectroscopic measurements have been made on 253/102No. A single rotational band was identified up to a probable spin of 39/2planck, which is assigned to the 7/2(+)[624] Nilsson configuration. The bandhead energy and the moment of inertia provide discriminating tests of contemporary models of the heaviest nuclei. Novel methods were required to interpret the sparse data set associated with cross sections of around 50 nb. These methods included comparisons of experimental and simulated spectra, as well as testing for evidence of a rotational band in the gammagamma matrix.

Abstract
Somatic Brassica napus (+) Arabidopsis thaliana hybrids with a cytoplasmic male sterility (CMS)-inducing cytoplasm were screened for fertility-restored plants. One line was selected and recurrently backcrossed with the maintainer line, B. napus, resulting in fertile/sterile segregating populations. Restriction fragment length polymorphism mapping showed the co-segregation of A. thaliana chromosome (chr) III markers with the fertility trait. As it was not possible to stabilise the fertility trait via selfings, a dihaploidisation strategy was assessed. Ninety haploid plants were regenerated and analysed with numerous simple sequence length polymorphism (SSLP) markers. Markers covering both arms of A. thaliana chr III were present in two plants, whereas no A. thaliana DNA could be detected in the other plants. Following colchicine-induced chromosome doubling only these two plants with A. thaliana DNA produced fertile offspring. In one of the two lines, however, the A. thaliana-specific DNA markers and fertility were lost in subsequent generations. The other line remained fertile after repeated selfings. Using genomic in situ hybridisation (GISH) we were able to demonstrate that this latter line possessed a disomic addition of the A. thaliana chromosome. The restored line was comparable to the maintainer line with respect to flower morphology, but the petals and stamens were slightly reduced in size. The homeotic conversion of stamens to pistil-like structures, which is typical for the CMS line, was reversed, and stamens with a normal appearance with viable pollen appeared. Flowering time was as in the CMS line-in both lines it was delayed in comparison to the maintainer line. The introgressed chromosome also contributes to several pleiotropic effects, such as reduced leaf crinkling and shorter stems. The ability to restore fertility through the introgression of nuclear genes from the main cytoplasmic donor species indicates that the CMS trait in this system mainly is due to B. napus/ A. thaliana alloplasmic incompatibility and not mitochondrial DNA rearrangements. Further exploitation of the material is discussed.

Abstract
BACKGROUND Stachybotrys chartarum is a damp building mould and a potent toxin producer that has been related to serious cases of respiratory health problems. However, the direct link between exposure and health symptoms has not been established. OBJECTIVE To examine the mechanism by which exposure to spores of satratoxin producing and non-producing S. chartarum strains induce inflammatory responses in murine lungs. METHODS BALB/c mice were intranasally exposed for 3 weeks to spores of a satratoxin-producing and a non-producing S. chartarum strain. Inflammatory cell infiltration was characterized from bronchoalveolar lavage (BAL) fluid. Cytokine and chemokine mRNA expression in lung tissue was measured with real-time PCR. Bronchial responsiveness to methacholine (MCh) was determined by whole-body plethysmography and serum antibody levels by ELISA. RESULTS A dose-dependent increase in monocytes, neutrophils and lymphocytes was observed in BAL fluid after intranasal (i.n.) instillation of S. chartarum spores. There was no difference in the BAL between exposure to the satratoxin-producing and the non-producing strains. Infiltration of inflammatory cells was associated with an induction of pro-inflammatory cytokine (IL-1beta, IL-6 and TNF-alpha) and chemokine (CCL3/MIP-1alpha, CCL4/MIP-1beta and CCL2/MCP-1) mRNA levels in the lungs. Interestingly, CXCL5/LIX was the only chemokine that showed significantly higher mRNA levels after exposure to the satratoxin-producing strain compared with the non-producing strain. MCh-induced bronchial responsiveness was not altered significantly after mould instillation. Moreover, no significant increase in total or specific IgE, IgG2a and IgG1 antibody levels were found after S. chartarum exposure. CONCLUSION These results indicate that lung inflammation induced by i.n. instillations of S. chartarum spores is regulated by the induction of pro-inflammatory cytokines and leucocyte-attracting chemokines. The data also imply that S. chartarum-derived components, other than satratoxins, are mediating the development of this inflammatory response.

Abstract
Numerous Brassica napus (+) Arabidopsis thaliana somatic hybrids were screened for male sterility and aberrant flower phenotypes. Nine hybrids were selected and backcrossed recurrently to B. napus. The resulting lines displayed stable maternal inheritance of flower phenotypes. Nuclear and organellar genomes were characterized molecularly using RFLP analysis. No DNA from A. thaliana was found in the nuclear genome after six back-crosses, whilst the mitochondrial genomes contained rearranged DNA from both A. thaliana and B. napus. Each line tested had a unique RFLP pattern of the mitochondrial DNA (mtDNA) that remained unchanged between the BC(3) and BC(6) generation. The plastid genomes consisted of B. napus DNA. Five lines of the BC(5) generation were subjected to more comprehensive investigations of growth, morphology and fertility. On the basis of these investigations, the five CMS lines could be assigned to two groups, one represented by three lines displaying reduced vegetative development, complete male sterility, and homeotic conversions of stamens into feminized structures. The second group, represented by the other two lines, were not completely male-sterile but still displayed severely affected flower morphologies. These two lines did not display any reduction in vegetative development. For both groups only stamens and petals suffered from the morphological and functional aberrations, while the sepals and pistils displayed normal morphology. All plants were fully female-fertile. Different rearrangements of the mitochondrial genome disturbed nuclear-mitochondrial interactions and led to various types of aberrant growth and flower development. The existence of numerous CMS lines with different mitochondrial patterns involving a species with a sequenced genome offers new opportunities to investigate the genetic regulation of CMS and its associated developmental perturbations.

Abstract
The spectrum of prompt conversion electrons emitted by excited 254No nuclei has been measured, revealing discrete lines arising from transitions within the ground state band. A striking feature is a broad distribution that peaks near 100 keV and comprises high multiplicity electron cascades, probably originating from M1 transitions within rotational bands built on high K states.

Abstract
Excited states in (216)Th were investigated via prompt and delayed gamma decays and the recoil-decay tagging method. The decay schemes of the I(pi) = (8+), t(1/2) = 128(8) micros, the I(pi) = (11-), t(1/2) = 615(55) ns, and the I(pi) = (14+), t(1/2) > or = 130 ns isomers were established. The configuration pi h(9/2)f(7/2) is assigned to the I(pi) = (8+) isomer, which implies that the h(9/2) and f(7/2) states are nearly degenerate. This is ascribed to increased binding of the f(7/2) orbital by its coupling to a low-lying I(pi) = (3-) state at E(x) = 1687 keV. The role of octupole and pairing correlations for a Z = 92 shell closure prediction is discussed on the basis of shell model calculations.

Abstract
The entry distribution in angular momentum and excitation energy for the formation of 254No has been measured after the 208Pb(48Ca,2n) reaction at 215 and 219 MeV. This nucleus is populated up to spin 22Planck's over 2pi and excitation energy greater, similar6 MeV above the yrast line, with the half-maximum points of the energy distributions at approximately 5 MeV for spins between 12Planck's over 2pi and 22Planck's over 2pi. This suggests that the fission barrier is greater, similar5 MeV and that the shell-correction energy persists to high spin.

Abstract
The socioeconomic status (SES) of the family influences the cardiovascular risk status of children and adolescents; however, it is not as well known whether parental SES has any effect on the risk factor profile of young adults. The aim of the present study was to investigate the relations of different aspects of parental SES, namely occupation, education, income and living area, to the common cardiovascular risk factors of their offspring (n = 919) aged 18, 21 and 24 years as a part of the Cardiovascular Risk in Young Finns Study in 1986. Subjects from farming families and rural areas had the highest serum total and low-density lipoprotein cholesterol values, and the lowest diastolic blood pressure compared with subjects from other occupational groups and subjects from urban regions. The diet of young adults from farming families and from rural areas contained more saturated fatty acids and less monounsaturated and polyunsaturated fatty acids. In addition, the body mass index was lower in subjects from urban regions compared with rural regions, and physical inactivity was less common in the urban group. Subjects with the highest parental occupational status smoked less compared with those with the lowest status. Parental education related inversely to physical inactivity and directly to dietary polyunsaturated fatty acids. The income level of the family associated positively with frequent inebriation by alcoholic beverages and inversely with the percentage of dietary energy from fat. In conclusion, there were modest inverse associations between different indicators of the SES of parents and some of the traditional risk factors of their offspring in young adulthood, which may contribute to the future risk of cardiovascular diseases.

Abstract
BACKGROUND Low educational level is associated with an increased risk of coronary heart disease. The aim of the present study was to examine the relationships between education and common cardiovascular risk factors in young adults. METHODS Trends in conventional risk factors of young adults aged 21, 24, 27 and 30 years in 1992 (n = 443) were examined across the educational groups as part of a 12-year follow-up study, the Cardiovascular Risk in Young Finns Study. Education was determined as participants' own educational level and as parental years of schooling. RESULTS In males, subject's own education was related inversely and independently of parental school years to serum total and low density lipoprotein (LDL) cholesterol concentration, smoking and body mass index. In females, participant's own educational level associated inversely with smoking and physical inactivity. Parental school years was associated inversely and independently of one's own educational level with serum total and LDL cholesterol values and waist-hip ratio in females. In both genders, parental education was a stronger determinant of diet (butter use) than one's own educational level. CONCLUSIONS The least educated young adults have adopted a more adverse lifestyle than the more educated. The risk factor profile in young adulthood, especially in females, is still affected by parental education. The influences of one's own and parental educational level on vascular risk profile should be taken into consideration when planning public health campaigns among young adults.

Abstract
We examined whether regulation of glutamine: fructose-6-phosphate amidotransferase (GFA), the rate-limiting enzyme of the hexosamine pathway, is tissue specific and if so whether such regulation occurs at the level of gene expression. We compared GFA activity and expression and levels of UDP-hexosamines and UDP-hexoses between insulin-sensitive (liver and muscle) tissues and a glucose-sensitive (placenta) tissue from 19 day pregnant streptozotocin diabetic and non-diabetic rats. In pregnant non-diabetic rats GFA activities averaged (1521+/-75 pmol/mg protein x min) in the placenta, 895+/-74 in the liver and 81+/-11 in muscle (p<0.001 between each tissue). In the diabetic rats, GFA activities were approximately 50% decreased both in the liver (340+/-42 pmol/mg protein x min, p<0.05 vs control rats) and in skeletal muscle (46+/-3, p<0.05) compared to control rats. In the placenta, GFA activities were identical between diabetic (1519+/-112 pmol/mg protein x min) and non-diabetic (1521+/-75) animals. In the liver, the reduction in GFA activity could be attributed to a significant decrease in GFA mRNA concentrations, while GFA mRNA concentrations were similar in the placenta between diabetic and non-diabetic animals. UDP-N-acetylglucosamine (UDP-GlcNAc), the end product of the hexosamine pathway, was significantly reduced in the liver and in skeletal muscle but similar in the placenta between diabetic and non-diabetic rats. In summary, GFA activity and expression and the concentration of UDP-GlcNAc are decreased in the liver but unaltered in the placenta, although GFA activity is almost 2-fold higher in this tissue than in the liver. These data provide the first evidence for tissue specific regulation of GFA and for its regulation at the level of gene expression.

Abstract
As a part of the large project Cardiovascular Risk in Young Finns, the purpose of the present study was to examine how adult physical activity is influenced by early physical activity and current social and health-related factors. A total of 2411 children and adolescents aged 9, 12, 15 and 18 years were randomly selected from five university towns and their rural surroundings in 1980. They were followed up for 12 years by means of questionnaires. In 1992 they were 21, 24, 27 and 30 years old. The results showed that early physical activity and current social and health-related behaviours were significantly related to the level of adult physical activity. Multivariable analyses indicated that early physical activity, in particular, was the best predictor of adult physical activity in all groups, with the exception of the 21-year-old women. The social and health-related factors such as occupation, employment status and smoking also predicted physical activity in some age-gender groups.

Abstract
BACKGROUND The influence of parental occupation on selected coronary heart disease risk factors was studied in a cohort of Finnish children aged 9, 12 and 15 years (n = 1211) as part of the Cardiovascular Risk in Young Finns Study in 1986. METHODS The relationships of parental occupation to serum lipid and apolipoprotein concentrations, blood pressure, obesity, smoking, physical activity, diet and birthweight were examined. The occupation of the parents was obtained by a questionnaire and classified as I: upper non-manual (22%), II: lower non-manual (26%), III: upper manual (32%), IV: lower manual (5%) and F: farmers (15%). RESULTS Highest serum total and how density lipoprotein cholesterol concentrations were found in classes IV and F. Boys from class IV had 7.1% higher total cholesterol concentrations compared to class I (4.98 mmol/l versus 4.65 mmol/l, P = 0.0033), whereas farmers' girls had 10.4% higher concentrations than girls from class III (5.31 mmol/l versus 4.81 mmol/l, P = 0.0057). Blood pressure was related to parental occupation only in boys, and the values were highest in class F. Boys from class IV smoked most often, and they also had lowest values for physical activity index and highest obesity indices. Farmers' children consumed significantly more saturated fat and cholesterol than children from other classes. In boys, the percentage of subjects with a low birthweight (< or = 10th percentile) was smallest in class I and greatest in class IV (7.1% versus 20.7%, P = 0.0330). CONCLUSIONS Socioeconomic status based on parental occupation is associated with several coronary heart disease risk factors already present in children. These differences should be taken into account in prevention programmes aimed at children at an increased risk for developing coronary heart disease as adults.

Abstract
Previous studies have reported increasing trends in physical activity in the Finnish population. These reports have not, however, included the perspective of cardiorespiratory stress in adolescent and young adults. We examined the present patterns of physical activity among Finnish adolescents and young adults in 1992. We specifically assessed whether the young people experience the volume of physical activity that is believed to stress the cardiorespiratory system appropriately in order to increase the level of fitness. The subjects in the present study were participants of a large multicenter study of atherosclerosis precursors in children and young adults. Physical activity was measured with a self-administered questionnaire in 2255 adolescents and young adults (1015 males and 1240 females). The proportion of subjects undertaking the volume of physical activity believed to benefit the cardiorespiratory system appropriately was 19%. The proportion was higher in males than in females (26 vs 13%). The proportion of active subjects became smaller in older age groups in both sexes. Half the study population (51% of the males; 48% of the females) reported frequent leisure-time physical activity less than once a month. In conclusion, Finnish adolescents and young adults have low levels of physical activity on the average, and many young Finns seldom undertake the volume of physical activity believed to benefit the cardiopulmonary system. Young males seem to be physically more active than females.

Abstract
The authors studied the occurrence of common lifestyle risk factors, namely, nonprudent diet, smoking, physical inactivity, and frequent inebriation by alcohol in a cohort of young adults aged 18, 21, and 24 years (n = 484) as part of the Cardiovascular Risk in Young Finns Study in 1986. Risk habits showed significant clustering; the number of subjects was greater than expected in groups with zero and three of four risk habits and less than expected in the group with only one or two risk habits. Stepwise logistic regression analysis was used to find independent determinants for this clustering from a set of socioeconomic, demographic, and behavioral (type A components) determinants. The logistic model suggested several independent risk factors for risk habit clustering. These included male sex, aggressiveness, and past unemployment. Paying a lot of attention to health habits, higher education (being a student), good self-perceived health, and a high sense of responsibility seemed to be protective factors against risk habit clustering. The accumulation of risk habits was also associated with an atherogenic lipid and blood pressure profile (clustering of high density lipoprotein cholesterol/total cholesterol ratio, triglycerides, and diastolic blood pressure in their extreme tertiles). These findings show that common risk habits cluster among young adults. Knowledge about the determinants of this clustering will aid in the planning of future preventive strategies against cardiovascular diseases in young people.

Abstract
Eighty-five eyes of 75 patients were retrospectively followed up for 5 years after argon laser trabeculoplasty. The effects of some treatment and patients variables on the results of trabeculoplasty were assessed. The laser power level or visible burn effect on the chamber angle did not have any statistically significant impact on the success rate or degree of intra-ocular pressure (IOP) decrease. A statistically significant level was reached by the degree of chamber angle pigmentation and the number of pre-operative antiglaucomatous medication. In eyes where trabeculoplasty was given as primary therapy, the IOP decrease was greatest.

Abstract
In a multicenter, double-blind, single-dummy, group-comparative study, 169 patients received ophthalmic sodium cromoglycate 2% four times daily, and 170 patients received 4% ophthalmic sodium cromoglycate twice daily, together with placebo eye-drops twice daily, for the treatment of seasonal allergic conjunctivitis (SAC) to birch pollen. The treatment period was 4 weeks during the birch pollen season. Daily pollen counts were used to identify the peak 14-d period. Clinical examinations were made before the start of treatment, after 1 week of treatment, and at the end of the treatment period. Patients kept daily diary record cards of eye symptom severity and concomitant therapy. Symptoms were generally mild and, except for chemosis (week 4) and soreness (weeks 2 and 3), which were less in the 4% group (P < or = 0.05), no significant treatment differences were seen for symptoms or for antihistamine rescue therapy. Both treatments were considered to be very or moderately effective by more than 90% of patients, and no treatment differences occurred in either clinicians' or patients' opinions of efficacy. The results indicate that the use of 4% sodium cromoglycate eye-drops twice daily is as effective and well tolerated as 2% sodium cromoglycate four times daily in the treatment of birch-pollen conjunctivitis.

Abstract
A 4 week, multicentre, double-blind, double dummy, placebo controlled group comparative study was carried out during the birch pollen season to compare the efficacy and tolerability of 2% nedocromil sodium eye drops (twice daily) and 2% sodium cromoglycate eye drops (four times daily). Participants with a history of seasonal allergic conjunctivitis (SAC) were randomized to receive nedocromil sodium (60), sodium cromoglycate (61) or placebo (64). Clinical assessment of SAC showed improvement with both active treatments compared to placebo but symptomatology was low and only changes in photophobia and grittiness reached significance (P < 0.05). Patient diaries showed significant control of itching by both active treatments, compared to placebo, with no differences between the active preparations. Patients' opinions indicated a marked placebo effect: 73% of this group reported full or moderate control of symptoms, compared with 75% in sodium cromoglycate and 80% in the nedocromil sodium group. Unusual symptoms were most common (27 patients) with nedocromil sodium eye drops: P < 0.05 vs. placebo (15 patients). There were no serious adverse events. Nedocromil sodium eye drops (b.d.) and sodium cromoglycate eye drops (q.i.d.) were both considered clinically more effective than placebo in controlling symptoms of SAC due to birch pollen.

Abstract
A multicentre, group comparative open study was carried out on 68 patients to compare the effects of 2% sodium cromoglycate eyedrops and an oral antihistamine, terfenadine, on acute symptoms of seasonal allergic conjunctivitis. The study was continued for one week after the onset of acute symptoms. Both medications were equally efficient in reducing symptoms during the first hour of observation. During the one-week follow-up both medications reduced symptoms to a low level, and both medications were equally effective for allergic symptoms, except that terfenadine was more effective in reducing the watering of eyes.

Abstract
Lens opacity studies were performed using an electronic Lens Opacity Meter (Interzeag Opacity Lensmeter 701) in a population (n = 321) with ischaemic heart disease. These patients are participating in a trial targetting at the reduction of mortality and incidence of myocardial infarction using a cholesterol-lowering drug, simvastatin. A separate study to evaluate the reliability of the method showed good reproducibility. Repeated measurements after a short time-interval (2-10 days) gave statistically lower opacity values either due to a change in lens transparency or perhaps a change in pigment and cell dispersion in the aqueous caused by repeated mydriasis. Lens opacity values showed a highly significant positive correlation to age. Serum cholesterol, systolic blood pressure and smoking habits showed no significant correlations to the levels of lens opacity when adjustments for age were made.
