Absence of evidence is not evidence of absence: the colour–density relation at fixed stellar mass persists to z∼ 1*

M. C. Cooper et al. E-mail: 0 0 Some of the data presented herein were obtained at the W. M. Keck Ob- servatory, which is operated as a scientific partnership among the California Institute of

A study of the gas–star formation relation over cosmic time*

We use the first systematic data sets of CO molecular line emission in z∼ 1–3 normal star-forming galaxies (SFGs) for a comparison of the dependence of galaxy-averaged star formation rates on molecular gas masses at low and high redshifts, and in different galactic environments. Although the current high-z samples are still small and biased towards the luminous and massive tail of ...

Individual differences in trait rumination and the neural systems supporting cognitive reappraisal

Cognitive reappraisal can alter emotional responses by changing one’s interpretation of a situation’s meaning. Functional neuroimaging has revealed that using cognitive reappraisal to increase or decrease affective responses involves left prefrontal activation and goal-appropriate increases or decreases in amygdala activation (Ochsner, Bunge, Gross, Ochsner, Ray, et al., 2004). ...

Hip fracture in Hong Kong over the last decade - a comparison with the UK

living in Hong Kong.2 Moreover, the age- and sex-specific rates in Hong Kong Chinese slightly exceeded those in the UK2 in 1985. We report here a further investigation into the trends of C. Cooper,2

PARL Leu262Val is not associated with fasting insulin levels in UK populations

Aims/hypothesis PARL, the gene encoding presenilins-associated rhomboid-like protein, maps to chromosome 3q27 within a quantitative trait locus that influences components of the metabolic syndrome. Recently, an amino acid substitution (Leu262Val, rs3732581) in PARL was associated with fasting plasma insulin levels in a US white population (N=1031). This variant was also found to ...

Poor response to recombinant erythropoietin is associated with loss of T‐lymphocyte CD28 expression and altered interleukin‐10 production

Background. Recombinant erythropoietin (Epo) therapy is well established as an effective treatment for the anaemia of end‐stage renal disease. However, 5–10% of such patients do not respond adequately and an important contributory factor to this is chronic inflammation. Methods. The present study compares the circulating T‐cell phenotypes of haemodialysis patients who respond ...

Type 2 diabetes mellitus is associated with increased axial bone density in men and women from the Hertfordshire Cohort Study: evidence for an indirect effect of insulin resistance?

Aims/hypothesis Previous studies have suggested that the high bone density often observed in type 2 diabetic patients may be explained by insulin resistance. We explored this hypothesis in the Hertfordshire Cohort Study. Methods A total of 465 men and 444 women aged 59 to 71 years and with no prior diagnosis of diabetes attended a clinic where a glucose tolerance test was performed ...

The effects of aerobic exercise on metabolic risk, insulin sensitivity and intrahepatic lipid in healthy older people from the Hertfordshire Cohort Study: a randomised controlled trial

Aims/hypothesis We sought to determine the effect of an aerobic exercise intervention on clustered metabolic risk and related outcomes in healthy older adults in a single-centre, explanatory randomised controlled trial. Methods Participants from the Hertfordshire Cohort Study (born 1931–1939) were randomly assigned to 36 supervised 1 h sessions on a cycle ergometer over 12 weeks or ...

The role of AGN in the colour transformation of galaxies at redshifts z≈ 1

We explore the role of active galactic nuclei (AGN) in establishing and/or maintaining the bimodal colour distribution of galaxies by quenching their star formation and hence, causing their transition from the blue to the red cloud. Important tests for this scenario include (i) the X-ray properties of galaxies in the transition zone between the two clouds and (ii) the incidence of ...

European guidance for the diagnosis and management of osteoporosis in postmenopausal women

Summary Guidance is provided in a European setting on the assessment and treatment of postmenopausal women with or at risk from osteoporosis. Introduction The European Foundation for Osteoporosis and Bone disease (subsequently the International Osteoporosis Foundation) published guidelines for the diagnosis and management of osteoporosis in 1997. This manuscript updates these in a ...

The DEEP2 Galaxy Redshift Survey: the role of galaxy environment in the cosmic star formation history

Using galaxy samples drawn from the Sloan Digital Sky Survey and the DEEP2 Galaxy Redshift Survey, we study the relationship between star formation and environment at z∼ 0.1 and 1. We estimate the total star formation rate (SFR) and specific star formation rate (sSFR) for each galaxy according to the measured [O ii]λ 3727 Å nebular line luminosity, corrected using empirical ...

Birth Weight, Infant Weight Gain, and Cause-specific Mortality: The Hertfordshire Cohort Study

Low birth weight, a marker of adverse intrauterine circumstances, is known to be associated with a range of disease outcomes in later life, including coronary heart disease, hypertension, type 2 diabetes, and osteoporosis. However, it may also decrease the risk of other common conditions, most notably neoplastic disease. The authors describe the associations between birth weight, ...

The DEEP2 galaxy redshift survey: the evolution of the blue fraction in groups and the field

We explore the behaviour of the blue galaxy fraction over the redshift range 0.75 ≤ z ≤ 1.3 in the DEEP2 Survey, both for field galaxies and for galaxies in groups. The primary aim is to determine the role that groups play in driving the evolution of galaxy colour at high z. In pursuing this aim, it is essential to define a galaxy sample that does not suffer from redshift-dependent ...

The DEEP2 galaxy redshift survey: evolution of the colour–density relation at 0.4 < z < 1.35

Using a sample of 19 464 galaxies drawn from the DEEP2 Galaxy Redshift Survey, we study the relationship between galaxy colour and environment at 0.4 1, being larger in regions of greater galaxy density. At all epochs probed, we also find a small population of red, morphologically early-type galaxies residing in regions of low measured overdensity. The observed correlations between ...

Factors Associated with Osteoarthritis of the Hip and Knee in Hong Kong Chinese: Obesity, Joint Injury, and Occupational Activities

In 1998, a case-control study was conducted in Hong Kong on hospital patients with osteoarthritis of the hip (n = 138) and osteoarthritis of the knee (n = 658). Age- and sex-matched controls were recruited consecutively from general practice clinics in the same region. The following three risk factors were found to be associated with osteoarthritis of both the hip and the knee: ...

A deep Chandra survey of the Groth Strip – II. Optical identification of the X-ray sources

In this paper, we discuss the optical and X-ray spectral properties of the sources detected in a single 200-ks Chandra pointing in the Groth-Westphal Strip region. A wealth of optical photometric and spectroscopic data are available in this field providing optical identifications and redshift determinations for the X-ray population. The optical photometry and spectroscopy used here ...

The DEEP2 Galaxy Redshift Survey: the relationship between galaxy properties and environment at z∼ 1

We study the mean environment of galaxies in the DEEP2 Galaxy Redshift Survey as a function of rest-frame colour, luminosity, and [O-ii] 3727-Å equivalent width. The local galaxy overdensity for >14-000 galaxies at 0.75 < z < 1.35 is estimated using the projected third-nearest-neighbour surface density. Of the galaxy properties studied, mean environment is found to depend most ...
