OBJECTIVES Prevalence studies of the association between blood pressure and headache have shown conflicting results. The aim was to analyse the relation between blood pressure and risk of headache in a prospective study. METHODS A total of 22 685 adults not likely to have headache, had their baseline blood pressure measured in 1984-6, and responded to a headache questionnaire at follow up 11 ...

For the first time, a unique pumping scheme for the thulium 2.3 micrometer transition is proposed that is capable of enhancing the output power by almost a factor three when compared to the traditional pumping scheme at 960 nm. The best relation between 685 nm pump power and 960 nm pump power is shown. The achieved output power of 620 mW is the highest reported so far. Introduction Tunable lase...

BACKGROUND The purpose of this study was to assess the independent contribution of left bundle branch block (LBBB) on long-term mortality in a large cohort with symptomatic heart failure (HF) requiring hospitalization. METHODS AND RESULTS We studied a prospective cohort of 21 685 cases of symptomatic HF requiring hospitalization in the Register of Information and Knowledge about Swedish Heart...

Results of a systematic investigation of the vapour-liquid equilibria of 38 individual two-centre Lennard-Jones plus axial pointdipole model fluids (2CLJD) are reported over a range of reduced dipolar momentum 0 ≤ μ ≤ 20 and of reduced elongation 0 ≤ L ≤ 1.0. Temperatures investigated are from about 55 % to about 95 % of the critical temperature of each fluid. The NpT+Test Particle Method is us...

BACKGROUND Obesity is defined as an excess of total body fat and may be assessed by different methods. The objective of the present study was to establish the discriminatory power of anthropometric data in determining obesity. METHODS The subjects comprised 685 individuals, aged 20-79 years, sampled from a population-based survey. The following indicators were used: body mass index (BMI), wai...

A chlorophyll (Chl)-protein complex designated CPVI-4 becomes the major pigment-protein complex in Synechococcus sp. PCC7942 cells grown under conditions of iron limitation. Work by Laudenbach et al. (J Bacteriol [1988] 170: 5018-5026) has identified an iron-repressible operon, designated isiAB, containing the flavodoxin gene and a gene predicted to encode a Chl-binding protein resembling CP43 ...

BACKGROUND Obstructive sleep apnea (OSA) is associated with an increase in the prevalence and incidence of hypertension and cardiovascular diseases. Data about epidemiological characteristics of OSA in Chinese hypertensive populations is limited. METHODS Hypertensive subjects without a prior diagnosis of OSA were recruited, and the apnea-hyponea index (AHI) was assessed by polysomnography. Co...

Light amplification by stimulated emission of radiation (laser) is one of the most recent treatment modalities in dentistry. Low-level laser therapy (LLLT) is suggested to have biostimulating and analgesic effects through direct irradiation without causing thermal response. There are few studies that have investigated the efficacy of laser therapy in temporomandibular disorders (TMD), especiall...

Chlorine-containing disinfectants have been widely used all over the world to prevent COVID-19. However, little is known about potential risk of chlorine-containing in marine environment. Phaeodactylum tricornutum (P. tricornutum) a typical economic diatom, often as an effective biomarker ecotoxicology research. Here, present study has investigated effect different chlorine concentrations on ph...
