Childhood and adolescence are critical periods for the skeleton. Mechanical load has then been shown to be one of the best stimuli to enhance not only bone mass, but also structural skeletal adaptations, as both contributing to bone strength. Exercise prescription also includes a window of opportunity to improve bone strength in the late pre- and early peri-pubertal period. There is some evidence
Multicolor imaging of vegetation fluorescence following laser excitation is reported for distances of 50 m. A mobile laser-radar system equipped with a Nd:YAG laser transmitter and a 40-cm-diameter telescope was utilized. The laser light was Raman shifted to 397 nm with pulse energies of approximately 30 mJ. An image-intensified CCD camera with a specially designed split-mirror Cassegrainian teles
It is generally considered mammals and birds have five Tec family kinases (TFKs): Btk, Bmx (also known as Etk), Itk, Tec, and Txk (also known as Rlk). Here, we discuss the domains and their functions and regulation in TFKs. Over the last few years, a large number of genomes from various phyla have been sequenced making it possible to study evolutionary relationships at the molecular and sequence l
The rostral migratory stream (RMS) is the main pathway by which newly born subventricular zone cells reach the olfactory bulb (OB) in rodents. However, the RMS in the adult human brain has been elusive. We demonstrate the presence of a human RMS, which is unexpectedly organized around a lateral ventricular extension reaching the OB, and illustrate the neuroblasts in it. The RMS ensheathing the lat
An arrangement for real-time fluorescence imaging of capillary electrophoretic separations is described. A decoated capillary was excited along a substantial part of its length by a dye laser pumped with an XeCl excimer laser tuned to match the fluorophors in the sample. Light emitted from the migrating, fluorescent molecules was detected by an image-intensified, thermoelectrically cooled charge-c
Foreign investors in the Nordic countries are most likely to find country risk arising from problems on the supply side, as in corporate structural changes. Such changes manifest themselves in a tendency toward concentration and internationalization on the macroeconomic level. Country risk can be divided into political risk and the risk of suspended payments, both of which are directly related to
A high-performance and flexible analog-to-digital converter (ADC), that can be integrated in deep-submicron CMOS technology, is a key building block for reduced size, cost and power consumption of digital communication systems. This dissertation concerns the investigation of particular problems associated with the design of such ADCs. The problem of increased clock jitter sensitivity of low-pass
The present study investigated whether the rotation rate induced by amphetamine in 6-OHDA-lesioned rats was predictive of development of l-DOPA-induced dyskinesia (LID) and success of the lesion procedure in our experimental settings. We collected data from 312 6-OHDA-lesioned rats (from different sets of experiments). Rats were subjected to the amphetamine-induced rotation test (2.5mg/kg) and chr
In this study, tactile sensitivity of gloved hand in the cold operation has been investigated. The relations among physical properties of protective gloves and hand tactile sensitivity and cold protection were also analysed both objectively and subjectively. Subjects with various gloves participated in the experimental study during cold exposure at different ambient temperatures of -12°C and -25°C
BACKGROUND: Ion channel transient receptor potential A1 (TRPA1) and cannabinoid (CB) receptors are involved in mechanoafferent signaling from the bladder and the urethra. OBJECTIVE: To characterize TRPA1-, CB1-, and CB2-receptor activities in the human prostate. DESIGN, SETTING, AND PARTICIPANTS: Prostate specimens were obtained from 12 patients undergoing radical prostatectomy. We studied express
Objective. New technologies have emerged in recent years for the disinfection of hospital rooms and equipment that may not be disinfected adequately using conventional methods. There are several hydrogen peroxide-based area decontamination technologies on the market, but no head-to-head studies have been performed. Design. We conducted a head-to-head in vitro comparison of a hydrogen peroxide vapo
Popular Abstract in Swedish En harmonisk morfism är en funktion mellan två Riemannmångfalder, med den egenskapen att dess sammansättning med en lokal harmonisk funktion på bildmängden ånyo är en lokal harmonisk funktion på definitionsmängden. En sådan funktion är automatiskt en harmonisk avbildning, som dessutom är (svagt) horisontellt konform. I lokala koordinater betyder detta att funktionen måsA harmonic morphism is a map between two Riemannian manifolds with the property that its composition with a local harmonic function on the codomain is a local harmonic function on the domain. Such a map is automatically a harmonic map, satisfying an additional partial conformality condition called horizontal (weak) conformality. In local coordinates, this amounts to a non-linear, over-determined s
Mitochondrial reactive oxygen species (ROS) are implicated in signal transduction, inflammation, neurodegenerative disorders, and normal aging. Net ROS release by isolated brain mitochondria derived from a mixture of neurons and glia is readily quantified using fluorescent dyes. Measuring intracellular ROS in intact neurons or glia and assigning the origin to mitochondria are far more difficult. I
In 1987 we noticed excess adipose tissue in a patient with arm lymphedema and later, objective studies confirmed this clinical finding in patients with non-pitting arm lymphedema following breast cancer. A prospective study was begun in 1993, and its long-term results (15 years) shows overall complete reduction of the excess volume in patients with non-pitting arm lymphedema and that adipose tissu
