[1] Small mountainous rivers (SMR) export globally significant quantities of particulate organic carbon (POC) to the oceans, the composition of which may be distinct from POC delivered by major world rivers. To better constrain the controls on the DC signatures of POC suspended in SMR, we examined the temporal variability of DC and dC of POC suspended in the Santa Clara River, a SMR in Californ...

The application of brain-computer interfaces (BCI) shows promising results in stroke rehabilitation, but the underlying neural substrates and processes of successful BCI-based neurorehabilitation remain unclear. The goal of our present work was to identify the brain areas associated with successful visuomotor integration and motor learning (VMIL), and investigate their connection with successfu...

BACKGROUND Anorexia nervosa is a mental disorder with high mortality. AIMS To estimate standardised mortality ratios (SMRs) and to investigate potential prognostic factors. METHOD Six thousand and nine women who had in-patient treatment for anorexia nervosa were followed-up retrospectively using Swedish registers. RESULTS The overall SMR for anorexia nervosa was 6.2 (95% CI 5.5-7.0). Anor...

Transporters of the small multidrug resistance (SMR) family are small homo- or heterodimers that confer resistance to multiple toxic compounds by exchanging substrate with protons. Despite the wealth of biochemical information on EmrE, the most studied SMR member, a high-resolution three-dimensional structure is missing. To provide proteins that are more amenable to biophysical and structural s...

A small subset of the large pentatricopeptide repeat (PPR) protein family in higher plants contain a C-terminal small MutS-related (SMR) domain. Although few in number, they figure prominently in the chloroplast biogenesis and retrograde signaling literature due to their striking mutant phenotypes. In this review, we summarize current knowledge of PPR-SMR proteins focusing on Arabidopsis and ma...

Standard metabolic rate (SMR), active metabolic rate (AMR) and critical oxygen saturation (Scrit) were measured in Atlantic cod Gadus morhua at 5, 10 and 15) C. The SMR was 35·5, 57·0 and 78·2 mg O2 kg "1 h and Scrit was 16·5, 23·2 and 30·3%, at 5, 10 and 15) C, respectively. Previously reported SMR for Atlantic cod from arctic waters at 4) C was twice that measured at 5) C in the present study...

Cell size, measured as either volume or mass, is a fundamental indicator of cell state. Far more tightly regulated than size is density, the ratio between mass and volume, which can be used to distinguish between cell populations even when volume and mass appear to remain constant. Here we expand upon a previous method for measuring cell density involving a suspended microchannel resonator (SMR...

Due in part to their large size, aggressive temperament, and difficulty in handling, there are few physiological studies of adult crocodilians in the literature. As a result, studies comparing individuals across an ontogenetic series and comparisons among species are also lacking. We addressed this gap in knowledge by measuring standard metabolic rates (SMR) of three species of crocodilians (Cr...

BACKGROUND We conducted a retrospective cohort study of lung cancer among silicotics in China's metallurgical industries. The study cohort consisted of 4372 male silicotics diagnosed and alive before 1 January 1980. The follow-up period was 1 January 1980 to 31 December 1989. RESULTS Standardized mortality ratios (SMR) of all deaths, all cancers, chronic bronchopneumonia, pneumonia and pulmon...

To explore whether exposure among firefighters to fire smoke could lead to an increased risk of cancer, lung disease, and heart disease, the mortality of 4546 firefighters who were employed by the cities of Seattle and Tacoma, WA and Portland, OR for at least one year between 1944 and 1979 were compared with United States national mortalities and with mortality of police officers from the same ...
