Information on objectively assessed physical activity in elderly people is scarce. The aim of this study was to investigate accelerometer measures in elderly women, and its relation to other indices of physical activity and bone density. A subset of 57 women, all 80 years old, (range 80.0-80.7) of the Malmo OPRA study was equipped with an MTI accelerometer for a period of 5-7 days. A 7-day activit

In view of the complexity of the wing-beat kinematics and geometry, an important class of theoretical models for analysis and prediction of bird flight performance entirely, or almost entirely, ignores the action of the wing itself and considers only the resulting motions in the air behind the bird. These motions can also be complicated, but some success has previously been recorded in detecting a

The paradigmatic task for participants in studies on deception is to assess veracity on the basis of a single statement. However, in applied contexts, lie catchers are often faced with multiple statements (reported by one or several suspects). To appreciate this mismatch, we conducted a study where each member of 10 truth-telling pairs and 10 lying pairs (reporting fabricated alibis) was interroga

OBJECTIVE: It has been estimated that alcohol drinking increases the risk of breast cancer in women by approximately 7% for each increment of 10 g alcohol per day. However, the few studies conducted on breast cancer among men have failed to detect an association with quantitative measures of alcohol drinking, even if the alcohol intake is generally higher in men than in women. On the other hand, i

The taurine and zebuine cattle breeds comprise the majority of the world cattle population but their taxonomic status is still controversial. The two forms of cattle are currently classified as Bos taurus and Bos indicus species and are differentiated primarily by the presence or absence of a hump. However, these two species hybridize readily, producing fully fertile offspring. We have determined

Comparative and functional genomics are powerful tools to advance the understanding of the molecular basis of cancer. It is believed that genes are epigenetically regulated and, thus, each tumor type and stage will be characterized by a gene expression fingerprint. In this study we identified genes that are differentially expressed in ductal carcinoma in situ and invasive ductal carcinoma of the b

Background - Immune responses against oxidized low- density lipoprotein ( LDL) play an important role in atherosclerosis. The aim of this study was to investigate if humoral immune response against specific oxidized LDL antigens, such as aldehyde- modified peptide sequences of apolipoprotein B- 100, reflects disease activity and structure of atherosclerotic plaques. Methods and Results - Plaques w

A simple labeling approach is presented based on protein expression in [1-C-13]- or [2-C-13]-glucose containing media that produces molecules enriched at methyl carbon positions or backbone C-alpha sites, respectively. All of the methyl groups, with the exception of Thr and Ile(delta 1) are produced with isolated C-13 spins (i.e., no C-13-C-13 one bond couplings), facilitating studies of dynamics

OBJECTIVE: To investigate differences in snuff consumption, socio-demographic and psychosocial characteristics between baseline daily smokers who had remained daily smokers, become intermittent smokers or stopped smoking at the 1-year follow-up. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: A population of 12 507 individuals aged 45-69 years, interviewed at baseline in 1992-94 and at a 1-year fo

Proteorhodopsins are bacterial light-dependent proton pumps. Their discovery within genomic material from uncultivated marine bacterioplankton caused considerable excitement because it indicated a potential phototrophic function within these organisms, which had previously been considered strictly chemotrophic(1). Subsequent studies established that sequences encoding proteorhodopsin are broadly d

Treatment with omeprazole, a long-acting proton pump inhibitor of acid secretion, induces hypergastrinemia. In chickens, omeprazole induces growth not only of the acid-producing mucosa (probably reflecting the trophic action of gastrin), but also of the parathyroid glands (hypertrophy + hyperplasia), while suppressing bone density and body weight gain without affecting blood calcium. The first par

Background: Ultraviolet (UV)-curing nail polishes based on acrylates or methacrylates are currently also available for non-professional use. The Swedish Medical Products Agency recently prohibited one brand of UV-curing polish, because several consumers reported undesirable effects after using it. Objectives: To investigate whether consumers with undesirable effects after using the UV-curing nail

A semistructured personal interview was performed with 29 carriers of hemophilia A or B, 1-5 years after a pregnancy in which prenatal diagnosis (PND) was performed by fetal blood sampling. Fetal blood sampling by fetoscopy was significantly more often reported by the women to the more trying than expected than was ultrasound-guided heart puncture. Of 29 women 13 was classified as having experienc

CD8(+) T cells in chronic viral infections such as HIV develop functional defects including loss of interleukin-2 (IL-2) secretion and decreased proliferative potential that are collectively termed 'exhaustion'. Exhausted T cells express increased amounts of multiple inhibitory receptors, such as programmed death-1 (PD-1), that contribute to impaired virus-specific T cell function. Although revers

Urban green infrastructure (UGI) has been increasingly promoted as a key measure to mitigate heat stress in cities caused by the urban heat island effect and climate change impacts, including climate variability and extremes. However, comparable information concerning the performance of different UGI types to moderate such impacts is mostly lacking. This creates serious challenges for urban planne

Finite-element programs can be used for designing columns and their bracing systems. It is well known, however, that the output obtained from such programs is highly dependent upon the input (such as imperfections and stiffness properties). In the present study, the effects of imperfections on the predicted strength and stiffness requirements of steel columns and of their bracing systems are inves
