Ekologisk Marxism: att göra vänstern grön

För den spirande miljömedvetenheten på 1960-talet måste det har tett sig uppenbart att den socialistiska rörelsen – på båda sidor om verkliga och ideologiska murar – prioriterade sysselsättning och växande (privat och offentligt) konsumtionsutrymme långt före ekologiska hållbarhetsfrågor, och trots att miljöpolitik nu har lagts till andra politikområden har den prioritetsordningen knappast ändrats

Calcitonin gene-related peptide (CGRP) levels during glyceryl trinitrate (GTN)-induced headache in healthy volunteers

The role of nitric oxide (NO) in migraine has been studied in the experimental glyceryl trinitrate (GTN)-infusion headache model. We hypothesized that GTN-induced headache may activate the trigeminovascular system and be associated with increased levels of sensory neuropeptides, including calcitonin gene-related peptide (CGRP). CGRP, vasoactive intestinal peptide (VIP), neuropeptide Y (NPY) and so

Communicating Alcohol Narratives: Creating a Healthier Relationship with Alcohol

Alcohol, like mental health, is a neglected topic in public health discussions. However, it should be defined as a priority public health area because the evidence available to support this is very persuasive. Although only half the world's population drinks alcohol, it is the world's third leading cause of ill health and premature death, after low birth weight and unsafe sex, and the world's grea

Self-Organizing Body Maps in the Spinal Cord

During development primary afferents grow into and establish neuronal connections in the spinal cord, conveying information of the anatomical and mechanical properties of the body. This body representation forms the basis for how we perceive sensory information and control our movements. Subsequently, the strength of the sensory input to spinal sensorimotor circuits is functionally adjusted by an

Effects of increased physical activity and motor training on motor skills and self-esteem. An intervention study in school years 1 through 9

OBJECTIVE: The aim was to study effects on motor skills and self-esteem of an extension of the Swedish school subject Physical Education and Health (PEW and motor training during nine school years. DESIGN AND METHOD: An intervention group (n=161) had PEH and motor training five lessons (225 nun) and a matched control group (n=102) had regular PEH two lessons (90 min) per week. The method was hypot

Prospective Longitudinal Study of Thromboelastography and Standard Hemostatic Laboratory Tests in Healthy Women During Normal Pregnancy

BACKGROUND: Hemostatic disorders are common in obstetric complications. Thromboelastography (TEG (R)) simultaneously measures coagulation and fibrinolysis within 10 to 20 minutes. Our primary aim in this prospective longitudinal study was to obtain knowledge about physiological changes in TEG (R) variables during normal pregnancy and 8 weeks postpartum. The secondary aims were to compare TEG (R) v

AC-186, a Selective Nonsteroidal Estrogen Receptor beta Agonist, Shows Gender Specific Neuroprotection in a Parkinson's Disease Rat Model

Drugs that selectively activate estrogen receptor beta (ER beta) are potentially safer than the nonselective estrogens currently used in hormonal replacement treatments that activate both ER beta and ER alpha. The selective ER beta agonist AC-186 was evaluated in a rat model of Parkinson's disease induced through bilateral 6-hydroxydopamine lesions of the substantia nigra. In this model, AC-186 pr

Skin-to-skin care in neonatal intensive care units in the Nordic countries: a survey of attitudes and practices.

Aim: To investigate the application of skin-to-skin care (SSC) in the Nordic countries, the existence of guidelines for SSC and the attitudes of neonatal staff towards SSC. Methods: One questionnaire was distributed at unit level and one at staff level in all Nordic neonatal intensive care units (n = 109). Results: The unit questionnaire was answered by 95 (87%) units and the staff questionnaire b

Heat Transfer Characteristics of an Impinging Jet in Crossflow

The heat transfer characteristics of an impinging jet into a crossflow have been investigated by the liquid crystal thermography technique. The jet nozzle is circular and is inclined at 10 deg with respect to the target wall. In a turbulent flow regime, the effects of the jet Reynolds number, the velocity ratio, and the crossflow Reynolds number on the heat transfer are examined. The results show

PXL01 in Sodium Hyaluronate for Improvement of Hand Recovery after Flexor Tendon Repair Surgery: Randomized Controlled Trial.

Postoperative adhesions constitute a substantial clinical problem in hand surgery. Fexor tendon injury and repair result in adhesion formation around the tendon, which restricts the gliding function of the tendon, leading to decreased digit mobility and impaired hand recovery. This study evaluated the efficacy and safety of the peptide PXL01 in preventing adhesions, and correspondingly improving h

Cardiovascular Risk Genes in Prevention and Treatment Response

GENERAL AIM: To investigate how common single-nucleotide-polymorphisms (SNPs) that associate with cardiovascular disease (CVD) could be used in prevention and treatment of CVD. SUBJECTS: Subjects from the population-based Malmö-Diet-and-Cancer-(MDC)-Study (n=30447) and hypertensives from the Nordic-Diltiazem-(NORDIL)-Study (n=10881). METHODS AND RESULTS: A nine-SNP-lipid-genetic-risk-score was r

Branched Silver Nanowires as Controllable Plasmon Routers

Using polarization dependent scattering spectroscopy, we investigate plasmon propagation on branched silver nanowires. By controlling the polarization of the incident laser light, the wire plasmons can be routed into different wire branches and result in light emission from the corresponding wire ends. This routing behavior is found to be strongly dependent on the wavelength of light. Thus for cer

New printing technology and pricing

This case study analyzes five Swedish printing houses' pricing with respect to their investments in new printing technology. The new printing technology made it possible for the printing houses to market new products and services to meet the demand for shorter delivery times and full service solutions. Although this demand was apparent, the printing houses' opportunities to capitalize on their inv

The battleground of two Infections and a cancer: Human Papilloma Virus, premalignant lesions of the cervix and their interaction with Human Immunodeficiency Virus in southwestern Nigeria

Popular Abstract in English An increased risk of pre-cancer lesions of the cervix among HIV-infected women, and the positive impact of HIV treatment on its outcome has been reported globally. However there is paucity of information from west Africa with genetically distinct viral strains. Considering that HIV strains differ in the rate and pattern of HIV disease progression, a different outcome isBackground: The highest numbers of HIV-infected women are in sub- Saharan Africa, where the natural progression of HIV disease in the absence of treatment results in death before the onset of invasive cervical cancer. With improved access to treatment, several studies outside West Africa demonstrated an increased risk of pre-invasive cervical lesions among HIV-infected women and the positive impac

Machine Learning Algorithms for Improved Glaucoma Diagnosis

Primary open angle glaucoma, one of the leading causes of blindness in the world, constitutes a slow progressing condition characterized by damage to the optic nerve and retinal nerve fibre layer, and results in visual field defects afflicting the visual function. Highly specific and sensitive diagnostic tests able to detect the clinically significant glaucomatous changes in the structure of the n

Treatment of Critical Limb Ischaemia

Recommendations stated in the TASC II guidelines for the treatment of peripheral arterial disease (PAD) regard a heterogeneous group of patients ranging from claudicants to critical limb ischaemia (CLI) patients. However, specific considerations apply to CLI patients. An important problem regarding the majority of currently available literature that reports on revascularisation strategies for PAD

Reconstitution of water channel function and 2D-crystallization of human aquaporin 8.

Among the thirteen human aquaporins (AQP0-12), the primary structure of AQP8 is unique. By sequence alignment it is evident that mammalian AQP8s form a separate subfamily distinct from the other mammalian aquaporins. The constriction region of the pore determining the solute specificity deviates in AQP8 making it permeable to both ammonia and H(2)O(2) in addition to water. To better understand the

Mitogenomic relationships of placental mammals and molecular estimates of their divergences.

Molecular analyses of the relationships of placental mammals have shown a progressive congruence between mitogenomic and nuclear phylogenies. Some inconsistencies have nevertheless persisted, notably with respect to basal divergences. The current study has aimed to extend the representation of groups, whose position in the placental tree has been difficult to establish in mitogenomic studies. Both
