While heart rate (fH) has been used as an indicator of energy expenditure, quantitative data showing the relationship between these variables are only available for normothermic animals. To determine whether fH also predicts oxygen consumption ( ) during torpor, we simultaneously measured , fH and subcutaneous body temperature (Tsub) of a hibernator, Gould's long-eared bats (Nyctophilus gouldi,...

Although many years have passed from the recognition of otitis media with effusion (OME), there is much controversy on its etiology, pathogenesis, and treatment strategies. This condition occurs more frequently in infants and children. Moreover, it is more common in Eskimo and Native American than White American and Blacks. In addition, socioeconomic and cultural factors can affect its prevalen...

It is well documented that the hormone leptin regulates many central functions and that hippocampal CA1 pyramidal neurons are a key target for leptin action. Indeed, leptin modulates excitatory synaptic transmission and synaptic plasticity at the Schaffer-collateral input to CA1 neurons. However the impact of leptin on the direct temporoammonic (TA) input to CA1 neurons is not known. Here we sh...

PURPOSE To report micro- and ultrastructural features of internal limiting membranes (ILMs) in various maculopathies and to evaluate the effects of indocyanine green (ICG) and triamcinolone acetonide (TA) on epiretinal proliferations associated with ILM and on retinal cleavage plane. METHODS ILMs from various maculopathies were evaluated regarding presence or absence of membrane-associated ce...

Rehabilitation following spinal cord injury is likely to depend on recovery of corticospinal systems. Here we investigate whether transmission in the corticospinal tract may explain foot drop (inability to dorsiflex ankle) in persons with spinal cord lesion. The study was performed in 24 persons with incomplete spinal cord lesion (C1 to L1) and 15 healthy controls. Coherence in the 10- to 20-Hz...

Detailed microstructural investigation of ion beam deposited giant magnetoresistance ~GMR! spin valves has been carried out using various techniques of transmission electron microscopy ~TEM! and x-ray diffraction. Two fcc phases, i.e., FeMn and NiFe/Co/Cu/Co/NiFe have been identified in ion-beam deposited Ta ~50 Å!/FeMn ~80 Å!/NiFe~30 Å!/Co~15 Å!/Cu~33 Å!/Co~15 Å!/NiFe~60 Å!/Ta~25 Å!/Si~001! sp...

BACKGROUND Healthy, nulliparous women at low risk for preterm birth would not usually undergo transvaginal scanning at the 20-week morphology scan. The study aimed to determine whether transabdominal cervical measurement would be sufficient to exclude a short cervix in this population. AIMS To investigate the relationship between transabdominal (TA) and transvaginal (TV) ultrasound measuremen...

This study assessed the accuracy of the technical absorbent (TA) method for measuring local sweat rate (LSR) relative to the well-established ventilated capsule (VC) method during steady-state and nonsteady-state sweating using large and small sample surface areas on the forearm and midback. Forty participants (38 males and two females) cycled at 60% peak oxygen consumption for 75 min in either...
