Adaptation of Multi-Segmented Body Movements during Vibratory Proprioceptive and Galvanic Vestibular Stimulation.

Control of orthograde posture and use of adaptive adjustments constitutes essential topics of human movement control, both in maintenance of static posture and in ensuring body stability during locomotion. The objective was to investigate, in twelve normal subjects, how head, shoulder, hip and knee movements and torques induced towards the support surface were affected by vibratory proprioceptive

Blunted pubertal growth after leukemia: a new pattern of growth hormone insufficiency

Growth, age at menarche and spontaneous GH secretion were studied in girls after treatment for acute lymphoblastic leukemia (ALL). These girls had normal prepubertal growth but subnormal pubertal growth. Mean final height was 1 SD less than expected before puberty. The average age at menarche was significantly lower than the normal mean for Swedish girls. The mean 24-hour GH secretion was severely

Synthesis and conformational studies of a Leu-enkephalin amide analogue containing a ferrocene substructure

Solution phase synthesis of a constrained Leu(5)-enkephalin amide analogue 10 is reported, in which the cyclic ferrocenyl containing subunit 7 was introduced as a mimetic of the tetrapeptide Tyr-Gly-Gly-Phe unit. Temperature dependence of the chemical shift of the amide protons of 10 indicated a hydrogen bond between the same amino acid residues as observed for the natural Leu-enkepalin in the sin

Smoking during pregnancy: comparison of self-reports and cotinine levels in 496 women

Objective. To validate self-reported smoking habits in smoking pregnant women and estimate the prevalence of substantial exposure to passive smoking in non-smoking pregnant women. Design. Retrospective, quantitative study, consecutively collected samples. Setting. One antenatal clinic in Blekinge County, Sweden. Subjects. 509 pregnant women. Method. Information about smoking habits were taken from

Characterization of human myeloid progenitors and their differentiation

Popular Abstract in Swedish I blodet finns röda och vita blodkroppar eller blodceller, som är nödvändiga för vår överlevnad. Blodcellerna utvecklas i benmärgen från gemensamma ursprungsceller, så kallade stamceller och en konstant nyproduktion pågår genom hela livet. Under produktionen av mogna celler tillväxer och delar sig cellerna och får allt mer specialiserade egenskaper. Denna specialiseringAll hematopoietic cells are derived from the hematopoietic stem cells (HSCs) in a continuous and dynamic process, regulated by a network of transcription factors in different combinations and extrinsic signals from growth factors (GFs) and other factors in the microenvironment. In the initial stages of hematopoiesis HSCs differentiate to progenitor cells with gradually more restricted lineage pote

A 10-bit 5-MS/s successive approximation ADC cell used in a 70-MS/s ADC array in 1.2-um CMOS

A 10-bit 5-MS/s successive approximation ADC cell and a 70-MS/s parallel ADC array based on this cell, designed and fabricated in a 1.2-?m CMOS process, are presented. The ADC cell was designed to have an input bandwidth of more than 35 MHz and a sampling time of 14 nS at a clock rate of 70 MHz. The parallel ADC array consists of 14 such cells which are timed in one clock cycle skew successively i

Physics with REX-ISOLDE and MINIBALL

REX-ISOLDE is an experiment at ISOLDE/CERN with the aim to study the nuclear structure of neutron-rich nuclei using radioactive ion beams up to 2.2 MeV/u. The highly-efficient gamma-ray detector set-up MINIBALL will be used to explore reactions induced by Coulomb excitation or neutron transfer.

A global survey of physicians' perceptions on cholesterol management: the From The Heart study

Aims: Guidelines for cardiovascular disease (CVD) prevention cite high levels of low-density lipoprotein cholesterol (LDL-C) as a major risk factor and recommend LDL-C goals for various risk groups. Lifestyle changes are advised as first-line treatment for patients with high cholesterol, and statins are recommended in high-risk patients. The From The Heart study investigated current practice for t

A theoretical study of the bonding in trivalent americium complexes

An account of the electronic structure of AmF3 and AmCl3 has been obtained by Complete Active Space calculations (CASSCF and CASPT2) using either a scalar Douglas-Kroll-Hess Hamiltonian or a relativistic effective core potential. It has been compared to the description obtained by density functional theory (DFT) methods combined with a quasi-relativistic ZORA approach, either in the scalar or two-

Synthesis of effects in four Arctic subregions

An assessment of impacts on Arctic terrestrial ecosystems has emphasized geographical variability in responses of species and ecosystems to environmental change. This variability is usually associated with north-south gradients in climate, biodiversity, vegetation zones, and ecosystem structure and function. It is clear, however, that significant east-west variability in environment, ecosystem str
