An In Vitro Model for Studying Neuromuscular Transmission in the Mouse Pharynx.

The muscles of the pharynx are controlled by networks of neurons under the control of specific regions in the brain stem, which have been fairly well studied. However, the transmission between these neurons and the pharyngeal muscles, at the motor end plates, is less well understood. Therefore, an in vitro model for the study of neuromuscular transmission in the pharyngeal muscle of the mouse was

Changes in glycoprotein expression between primary breast tumour and synchronous lymph node metastases or asynchronous distant metastases.

Breast cancer is a very heterogeneous disease and some patients are cured by the surgical removal of the primary tumour whilst other patients suffer from metastasis and spreading of the disease, despite adjuvant therapy. A number of prognostic and treatment predictive factors have been identified such as tumour size, oestrogen (ER) and progesterone (PgR) receptor status, human epidermal growth fac

Early vascular aging (EVA): consequences and prevention.

It has often been recognized that a discrepancy exists during the clinical consultation between the chronological age of a patient on the one hand with the signs and symptoms of biological age that can be recorded on the other hand. In cardiovascular medicine this is obvious when a heavy smoker presents with features of early biological aging, for example skin appearance and impaired lung function

The impossibility of corporate ethics: for a Levinasian approach to managerial ethics

The moral philosophy of Levinas offers a stark prospectus of impossibility for corporate ethics. It differs from most traditional ethical theories in that, for Levinas, the ethical develops in a personal meeting of one with the Other, rather than residing in some internal deliberation of the moral subject. Levinasian ethics emphasises an infinite personal responsibility arising for each of us in t

Hyperpolarized (3)He apparent diffusion coefficient MRI of the lung: Reproducibility and volume dependency in healthy volunteers and patients with emphysema.

PURPOSE: To measure the apparent diffusion coefficient (ADC) of hyperpolarized (HP) (3)He gas using diffusion weighted MRI in healthy volunteers and patients with emphysema and examine the reproducibility and volume dependency. MATERIALS AND METHODS: A total of eight healthy volunteers and 16 patients with emphysema were examined after inhalation of HP (3)He gas mixed with nitrogen (N(2)) during b

Monitoring and evaluating surgical care: defining perioperative mortality rate and standardising data collection.

Case volume per 100 000 population and perioperative mortality rate (POMR) are key indicators to monitor and strengthen surgical services. However, comparisons of POMR have been restricted by absence of standardised approaches to when it is measured, the ideal denominator, need for risk adjustment, and whether data are available. We aimed to address these issues and recommend a minimum dataset by

Use of calcium channel blockers and beta blockers as antihypertensives in relation to mortality in type 2 diabetes patients: a population-based observational study.

OBJECTIVES: In previous trials, patients with type 2 diabetes using calcium channel blockers (CCB) have suffered a less favourable outcome when compared with patients on other treatments. The present study was designed to compare mortality in type 2 diabetes patients using either CCB or beta blockers (BB) as antihypertensive agents. DESIGN: Retrospective observational study. Patients were followed

Scaffolding Executive Function Capabilities via Play-&-Learn Software for Preschoolers

Educational software in the form of games or so called “computer assisted intervention” for young children has become increasingly common receiving a growing interest and support. Currently there are, for instance, more than 1,000 iPad apps tagged for preschool. Thus, it has become increasingly important to empirically investigate whether these kinds of software actually provide educational benefi

Couples therapy: effectiveness of treatment and long-term follow-up

Most couples therapy theories are developed and tested in the USA. In this clinical study, we investigated such therapies in a Swedish context. Over 300 couples were enrolled in the study of whom just under half completed the end-of-treatment assessment and just over 40 per cent a two-year follow-up. At the start, the study group displayed severe problems in marital adjustment, dyadic interactions

Beta-catenin is involved in alterations in mitochondrial activity in non-transformed intestinal epithelial and colon cancer cells.

BACKGROUND: Alteration in respiratory activity and mitochondrial DNA (mtDNA) transcription seems to be an important feature of cancer cells. Leukotriene D(4) (LTD(4)) is a proinflammatory mediator implicated in the pathology of chronic inflammation and cancer. We have shown earlier that LTD(4) causes translocation of beta-catenin both to the mitochondria, in which it associates with the survival p

A peaks over threshold model for change-point detection by wavelets

Newly available wavelet bases on multi-resolution analysis have exciting implications for detection of change-points. By checking the absolute value of wavelet coefficients one call detect discontinuities in ail otherwise smooth curve even in the presence of additive noise. In this paper, we combine wavelet methods and extreme value theory to test the presence of ail arbitrary number of discontinu

Macroporous molecularly imprinted polymer/cryogel composite systems for the removal of endocrine disrupting trace contaminants

A new concept for the preparation of selective sorbents with high flow path properties is presented by embedding molecularly imprinted polymers (MIPs) into various macroporous gels (MGs). A MIP was first synthetized with 17β-estradiol (E2) as template for the selective adsorption of this endocrine disrupter. The composite macroporous gel/MIP (MG/MIP) monoliths were then prepared at subzero tempera

URAK LAWOI – A Field Study of an Indigenous People in Andaman Sea, Thailand and their Problem with Rapid Tourist Development (2005)

This essay is about the indigenous people Urak Lawoi in Andaman Sea, outside the west coast of Thailand. The study shows what happens to them when they are being deprived of their territory and are being forced to abandon their culture, lifestyle and traditional economic subsistence. Urak Lawoi have until recently maintained culture, language and lifestyle apart from the rest of Thai society. Dur

Use of anti-asthmatic drugs during pregnancy. 2. Infant characteristics excluding congenital malformations.

Objective To study the characteristics of the infants born to women who have used anti-asthmatic drugs during pregnancy. Material and methods Various characteristics of infants with mothers who had reported the use of anti-asthmatic drugs in early pregnancy (n=24,750) or had such drugs prescribed later during pregnancy by a maternity health care centre (n=763) were identified from the Swedish Medi

Follow-up of children with congenital clubfoot. Development of a new evaluation instrument.

Popular Abstract in Swedish Klumpfot är en medfödd fotfelställning, som drabbar 1 av 1000 barn. Behandlingen består initialt av korrektion av felställningen, genom töjning och eventuellt operation. Det finns flera alternativa metoder att genomföra töjningar, och flera alternativa operationsmetoder. När felställningen korrigerats övergår behandlingen till att bibehålla det uppnådda läget med hjälp Clubfoot is a congenital disorder, affecting about one of 1000 children. Treatment consists of initial correction of the deformity, followed by prolonged orthosis treatment to maintain the correction obtained. There are several different treatment options. Outcome studies, using reliable and valid instruments are rare. In this thesis an assessment instrument, Clubfoot Assessment Protocol (CAP) wa

Optimal age for preventing osteoporosis after menopause depends on effects of stopping treatment

The aim of this study was to model the effect of short (3 year) treatments for osteoporosis at different times after menopause on the risk of osteoporotic fracture and to assess the impact of strategies to target high-risk individuals. Treatment efficacy for hip, proximal forearm, shoulder, and spine fracture were computed from the relationship between bone mineral density (BMD) and fracture in wo
