| expression and release of neuroregulators during development: monoamines and neuropeptides. | the turnover of catecholamines (ca) was determined in the adrenal medulla and brain of rat fetuses and pups. in general we found a considerable increase soon after birth. the expression of mrna for ca-synthesizing enzymes was also considerably enhanced in the adrenals shortly after birth. furthermore, we demonstrated increased expression of neuropeptides after birth, increased synthesis of mrna encoding for neuropeptide y in the adrenals 24 h after birth; and considerable activation of the subst ... | 1992 | 1306802 |
| acoustic chiasm v: inhibition and excitation in the ipsilateral and contralateral projections of lso. | when this series of experiments was begun in 1984, the activity of each lateral superior olive (lso) in the mammalian hindbrain was known to encode the hemifield of acoustic space containing a sound source. however, the almost random bilaterality of its ascending projections seemed to jumble that identification before reaching the midbrain. at the same time, electrophysiological studies of lso and its efferent target in the inferior colliculus, along with the strictly contralateral deficits in s ... | 2005 | 1317390 |
| gap-43 mrna localization in the rat hippocampus ca3 field. | gene expression of the axonal growth-associated protein, gap-43, has been studied in the adult rat brain by in situ hybridization histochemistry. this protein is synthesized at high levels in neuronal somata in immature and regenerating neurons, but after establishment of mature synaptic relations its synthesis generally declines sharply, thus providing a marker denoting propensity for exhibiting synaptic plasticity. detailed examination of the distribution of mrna for gap-43 in rat hippocampus ... | 1992 | 1317499 |
| patterns of substance use among methadone maintenance patients. indicators of outcome. | critics often cite the use of illicit drugs among methadone maintenance patients as evidence of this treatment modality's failure. the fact that methadone maintenance treatment does not lead quickly to abstinence in most clients can be a disappointment to treatment professionals and the public. by studying a cohort of 41 patients for their first year in a methadone maintenance program, this study revealed significant trends of diminished narcotic and cocaine use. however, increased benzodiazepin ... | 2005 | 1324987 |

| eccrine hidrocystoma: two cases of robinson and smith types. | two cases of eccrine hidrocystoma, one of which is a "classic" robinson type and the other a smith type, were reported. the walls of both cysts consisted mainly of two layers of flat or low cuboidal epithelial cells with eosinophilic cytoplasm. immunostaining for s-100 protein was negative in the cells of the cyst wall of the robinson type and only weakly positive in the inner luminal layer of the smith type. electron microscopically, the smith type showed double-layered cuboidal lining and cell ... | 2006 | 1401509 |
| study of acute intraoperative suprachoroidal hemorrhage. | acute intraoperative suprachoroidal hemorrhage or effusion (aish) was studied in a prospective manner over the past three years. in a general cataract surgery population of 2,523 patient eyes, 15 (0.6%) experienced an aish. results of a specific surgical management technique are presented. surgical control of the aish consisted of immediate closure of the incision and application of pressure directly to the eye. this tamponades the effusion or hemorrhage, which allows coagulation and completion ... | 2006 | 1403754 |
| [transient, prolonged, combined sicca syndrome of the eyes and mouth. occurrence along with a common cold in an 8-year-old girl]. | a girl of eight years fell ill with signs of common cold and bronchitis. already on the second day of illness, before any treatment was started, she showed symptoms of a sicca-syndrome, beginning in the eyes, later the mouth. ophthalmologic examination showed keratitis filiformis, histology of the salivary glands in the mucosa of the mouth was normal. local substitution therapy led to subjective improvement. the disorder of secretion persisted for four months only, then rapid restitutio ad integ ... | 2006 | 1435804 |
| why is the phosphorus content of human milk exceptionally low? | the phosphorus supply of children and adults is adequate, and usually in excess. therefore, it is surprising that in breast-fed infants phosphorus intake is very low. this is very rare among mammals. in infants three pathophysiological mechanisms argue in favour of a low, but adequate phosphorus intake in the presence of a balanced ratio of calcium to phosphorus. a low intestinal phosphorus concentration is an essential condition of an acid ph of the faeces, inhibiting the growth of potentially ... | 1992 | 1435825 |
| design and inhibitory properties of synthetic bowman-birk loops. | a cyclic tridecapeptide based on the sequence of an anti-tryptic loop of a bowman-birk inhibitor was synthesized, and demonstrated to be active as an inhibitor of trypsin. molecular modeling of this sequence suggested an improved sequence which demonstrated an order of magnitude improvement in the inhibitory constant. | 2006 | 1446974 |
| "raynaud's disease" in migraineurs: one entity or two? | two cases are reported of patients who were diagnosed as having both migraine and raynaud's disease. because they were able to achieve effective control of both headaches and extremity temperature after undergoing a comprehensive approach--utilizing medication, biofeedback, and psychotherapy--it is suggested that both conditions are manifestations of the same disorder. it is recommended that a first step in approaching concurrent diagnoses of this type involve combined treatment as is often used ... | 2006 | 1446993 |
| what role will residency education take in the profession by the year 2000? | residency education has enjoyed relatively slow but steady growth since its inception in the mid-1970s. a certain segment of recent graduates consider graduation from optometry school as entry level and perceive the need for additional clinical education. the creation of new residency programs and the expansion of existing ones may occur in a variety of settings. for residency education to realize its full potential, optometry must seek federal support for post-graduate clinical education. this ... | 2006 | 1447463 |
| aging and immunity. | the function of the immune system peaks at around puberty and gradually declines thereafter with advance in age. the age-related decline of immunological function primarily occurs in the t cell-dependent immune system and is generally associated with increase in susceptibility to infections as well as in incidence of autoimmune phenomena in the elderly. the age-related change in t cell-dependent immune functions can be ascribed to the physiological thymic atrophy which starts in an early stage o ... | 2006 | 1449050 |

| head group specificity in the regulation of phosphatidylcholine catabolism in rat hepatocytes. | previous studies have shown that the catabolism of pc is regulated in choline-deficient hepatocytes and the concentration of phosphatidylcholine (pc) might be an important regulatory factor (tijburg, l.b.m., nishimaki-mogami, t. and vance, d.e. (1991) biochim. biophys. acta, 1085, 167-177). in the present study we investigated the head group specificity of the regulation of pc catabolism. supplementation of choline-deficient rat hepatocytes, prelabeled with [3h]choline, with dimethylethanolamine ... | 1991 | 1892886 |
