RATIONALE: We recently suggested that dopamine on D1-like receptors is involved in the activation of goal-directed responses and the level of response activation is "reboosted" on the basis of an evaluation process involving D2-like receptors assessing "response efficacy". A main piece of evidence in support of this hypothesis was the ...

Extrinsic digit muscles contribute to both fingertip forces and wrist movements (FDP and FPL-flexion, EDC-extension). Hence, it is expected that finger forces depend on the wrist movement and position. We investigated the relation between grip force and wrist kinematics to examine whether and how the force (1) scales with wrist ...

Teaching about spirituality in medical school training is lacking. Spirituality is a dimension of humanity that can put experiences of health and illness into a meaningful context. Medical students might benefit from understanding how spirituality is an important element in learning to care for patients. Spirituality also provides a context ...

Increasing H2O2 levels in guard cells in response to environmental stimuli are recently considered a general messenger involved in the signaling cascade for the induction of stomatal closure. But little is known as to whether subsidiary cells participate in the H2O2-mediated stomatal closure of grass plants. In the present study, ...

Mesenchymal stem cells (MSCs) can be obtained from various sources. MSCs from different origins appear to have different preferences for differentiation. In this study, we have compared the in vivo osteogenic potential of adult MSCs from adipose tissue (AT) and bone marrow (BM) with fetal MSCs from umbilical cord (UC) ...

Women are found to be more religious than men and more likely to use religious coping. Only few studies have explored religious gender differences in more secular societies. This population-based study comprised 3,000 Danish men and women (response rate 45 %) between 20 and 40 years of age. Information about demographics, religiousness ...

Drug abuse-induced neurodegeneration can be triggered by elevated production of reactive oxygen species (ROS). Involvement of oxidative stress in acute amphetamine (AMPH)-mediated dopamine (DA) release, however, has not been completely understood yet. In order to elucidate the dopaminergic response of PC12 cells to a single dose of 10 μM AMPH, ROS ...

When systematic movement errors occur, the brain responds with a systematic change in motor behavior. This type of adaptive motor learning can transfer intermanually; adaptation of movements of the right hand in response to training with a perturbed visual signal (visuomotor adaptation) may carry over to the left hand. While ...

BACKGROUND: Breast cancer has been the most prevalent cancer in Japan since the 1990s. The mortality from breast cancer is increasing in Japan, whereas in other industrialized countries it has been decreasing since 1990. On the other hand, Japan faces unparalleled growth in its aging population. The aim of this ...

Complex glycan structures and their respective carrier molecules are often expressed in a cell type specific manner. Thus, glycans can be used for the enrichment of specific cell types such as neural precursor cells (NPCs). We have recently shown that the monoclonal antibodies 487(LeX) and 5750(LeX) differentially detect the LewisX ...

Management of relapsed acute lymphoblastic leukemia (ALL) is challenging and far from satisfactory. The treatment approaches are often varied and controversial. The duration of first remission, site of relapse, immunophenotypic and molecular characteristics of relapsed disease and response to therapy influence treatment outcome. There are three main therapeutic options i.e., ...

Naphthalene, the smallest polycyclic aromatic hydrocarbon (PAH), is found in abundance in crude oil, its major source in marine environments. PAH removal occurs via biodegradation, a key process determining their fate in the sea. Adequate estimation of PAH biodegradation rates is essential for environmental risk assessment and response planning using ...

Behavioral studies revealed that people were less likely to endorse negative information as self-descriptive. Neuroimaging studies have tapped on the neural mechanism underlying intentional self-processing of negative information using self-reflection tasks. Given that human self-processing occurring in our daily life is more likely to be captured by tasks involving incidental ...

Increased intratumoral expression of aromatase, the key enzyme for estrogen biosynthesis, is predicted to be of critical importance in the development of breast cancer. Recently, several germline rearrangements at 15q21 have been shown to cause overexpression of the aromatase gene CYP19A1 and resulting aromatase excess syndrome. To determine whether submicroscopic ...
