| proximal and distal changes in collagen content of peripheral nerve that follow transection and crush lesions. | collagen content of rat sciatic nerve was measured 10 weeks after either nerve transection or nerve crush. nerve transection led to a significant increase in fascicular collagen in nerve segments 2.5 mm proximal and distal to the injury site. remote from the transection, fascicular collagen was also significantly increased, this effect being most marked distally. nerve crush by comparison resulted in only a small increase in fascicular collagen, significantly less than after transection. the gre ... | 1986 | 3956663 |
| polypeptides during early conjugation in tetrahymena thermophila. | as tetrahymena thermophila cells differentiate from their vegetative life cycle to sexual reproduction, their polypeptide pattern undergoes a series of changes. these changes have been traced in extracellular, cellular, and subcellular compartments. the first alteration is induced by the nutritional shift-down and results in stimulation of at least one ciliary polypeptide and affects a series of polypeptides from other compartments. the second alteration is induced by mixing starved cells of com ... | 2013 | 3956587 |
| nadph/nadh-dependent cold-labile glutamate dehydrogenase in azospirillum brasilense. purification and properties. | a cold-labile glutamate dehydrogenase (gdh, ec 1.4.1.3) has been purified to homogeneity from the crude extracts of azospirillum brasilense. the purified enzyme shows a dual coenzyme specificity, and both the nadph and nadh-dependent activities are equally cold-sensitive. the enzyme is highly specific for the substrates 2-oxoglutarate and glutamate. kinetic studies with gdh indicate that the enzyme is primarily designed to catalyse the reductive amination of 2-oxoglutarate. the nadp+-linked acti ... | 1986 | 3956501 |
| cadmium acclimation and hormesis in fundulus heteroclitus during fin regeneration. | we have previously demonstrated that exposure to cadmium at 0.1 and 0.5 mg/liter will retard the rate of fin regeneration in fundulus heteroclitus. since there is a body of literature indicating that preexposure to low levels of metals may increase tolerance during subsequent exposure, these experiments were designed to investigate the effects of preexposure to cadmium, using fin regeneration as the parameter of effect. fish were exposed for 1 week to 0, 0.01, or 0.05 mg/liter cd. following this ... | 2014 | 3956462 |
| emotion socialization and expressive development in preterm and full-term infants. | the expressive behaviors of full-term and preterm infants and their mothers were examined during face-to-face interaction when the infants were approximately 2 1/2, 5, and 7 1/2 months old. videotapes of the sessions were coded on a second-to-second basis using izard's discrete emotion coding system. overall, infants showed a linear increase in positive effect, especially interest and joy, and a corresponding decrease in negative affect, especially pain and knit brow, with age; decrease in negat ... | 2009 | 3956316 |
| vitellogenin levels in male and female rainbow trout (salmo gairdneri richardson) at various stages of the reproductive cycle. | the immunoassayable vitellogenin (vtg) in plasma from male rainbow trout had the same molecular weight as authentic vtg from female fish. the vtg level in male trout was low (usually nanograms, occasionally up to a few micrograms, per ml) and did not correlate with the stage of sexual maturity. the plasma vtg level of female trout that were two years from first spawning was 200-fold higher than males of the same strain and age. the plasma vtg level of female rainbow trout rose approximately a mi ... | 2014 | 3956165 |

| impact of epidemic cholera in a previously uninfected island population: evaluation of a new seroepidemiologic method. | during an investigation of a 1982 cholera outbreak in truk, an area without endemic cholera, 254 post-outbreak serum specimens were collected from ill and well inhabitants of a single island. these were compared with 57 specimens collected in truk in 1964, when heat-labile toxin-producing enterotoxigenic escherichia coli was presumably endemic but cholera did not exist. the serum was tested for vibriocidal antibody and antitoxic antibodies to cholera toxin and heat-labile toxin and the ratio of ... | 1986 | 3946388 |

| virchow-robin space: a path of spread in neurosarcoidosis. | three cases of documented sarcoid meningoencephalitis were reviewed. computed tomography (ct) showed enhancing, perivascular, linear, and nodular areas along the subarachnoid space, extending deep into the white matter. in one case the perivascular granulomatous infiltration, which caused small vessel periangiitis, gave rise to a ct pattern closely resembling that of arteriovenous malformation or infarction with gyral enhancement. this infiltrative pattern might be seen in other chronic meningea ... | 2014 | 3945745 |
| vasopressin peptide (ddavp) may narrow the focus of attention in normal elderly. | administration of ddavp (1 desamino-8-d-arginine vasopressin), a form of vasopressin with little pressor action, has been shown to improve cognitive performance in the elderly. it remains unclear whether memory processes are specifically influenced or more general processes are altered. fifteen elderly subjects performed a central mental arithmetic task and a peripheral choice reaction time task in ddavp and control conditions. ddavp slowed reaction times to peripheral lights but did not alter a ... | 2014 | 3945698 |

| modification of excitation and inhibition evoked in dentate gyrus by perforant path stimulation: effects of aminophylline and kindling. | rats were implanted with chronic electrodes to stimulate the perforant path and record the elicited monosynaptic evoked potentials from the dentate gyrus of the hippocampal formation. dentate responses were examined in awake and anesthetized animals after exposure to saline and aminophylline (100 mg/kg, ip). in the awake animal, aminophylline treatment did not significantly alter the threshold or elicited amplitude of either the excitatory post-synaptic potential (epsp) or the population spike ( ... | 1986 | 3945669 |

| reliability and stability of the thymidine labeling index of breast carcinoma. | we have approached the question of the reliability of the thymidine labeling index (tli) of breast carcinoma by comparing paired samples. because the distribution of the tli is approximately lognormal, comparisons were made after transformation to the natural logarithm. for 38 paired samples from the primary carcinoma (biopsy versus residual tumor in mastectomy specimen), r, 0.89, p less than 0.0001. for 68 primary carcinomas versus their axillary metastases, r, 0.90, p less than 0.0001. substan ... | 2014 | 3945050 |
