Saltwater crocodiles, Crocodylus porosus, possess lingual salt glands which function to remove excess Na(+) and Cl(-) accumulated as a consequence of living in salt water. Little is known about the nature of ion transport systems in C. porosus salt glands and how these systems respond to an osmotic challenge. In the present study, we examined the distribution and regulation of the Na(+)/K(+)-AT...
PURPOSE To investigate the findings of infrared fundus autofluorescence in eyes with central serous chorioretinopathy (CSC). METHODS This study was an observational follow-up of 83 eyes of 80 consecutive patients with CSC recruited from a hospital referral practice. Infrared autofluorescence (IR-AF) findings and those of other clinical studies, including short-wave autofluorescence (SW-AF), f...
With a view to test how the branchial and intestinal tissues of fish, the two sites of metal acquisition, utilize the water-borne ferric [Fe(III)] iron and whether the accumulation of this form of iron influences cellular Na/K gradient in these tissues, the gills and intestines of climbing perch adapted to freshwater (FW) and acclimated to dilute seawater (20 ppt; SW) were analyzed for ouabain-...
Leprosy is a chronic infectious disease that is caused by the obligate intracellular pathogen Mycobacterium leprae (M.leprae), which is the leading cause of all non-traumatic peripheral neuropathies worldwide. Although both myelinating and non-myelinating Schwann cells are infected by M.leprae in patients with lepromatous leprosy, M.leprae preferentially invades the non-myelinating Schwann cell...
Transbranchial ammonia gradients and blood acid-base status have been examined in rainbow trout acclimated to fresh water (FW), 33% sea water (33% SW) and sea water (SW) and exposed to 1.0 mmol l-1 total ammonia (TAmm) at pH 7.9 for 24 h. At all three salinities trout maintained large negative (inwardly directed) NH3 and NH4+ gradients throughout the exposure, presumably by active excretion of ...
Marine teleosts actively excrete SO₄²⁻ and keep the plasma concentration of this ion much lower than that of environmental seawater (SW). We used the eel as a model to study the excretory mechanism of SO₄²⁻ because this euryhaline species changes SO₄²⁻ regulation drastically after transfer from freshwater (FW) to SW. Time-course studies showed that plasma SO₄²⁻ concentration decreased 3 days af...
Active brain stimulation to abate epileptic seizures has shown mixed success. In spike-wave (SW) seizures, where the seizure and background state were proposed to coexist, single-pulse stimulations have been suggested to be able to terminate the seizure prematurely. However, several factors can impact success in such a bistable setting. The factors contributing to this have not been fully inves...
Introduction: The NASA mission “Genesis” collected solar wind (SW) for laboratory analysis [1]. SW can serve as a proxy for the Sun’s composition, and thus the average composition of the solar nebula [2], provided that fractionation processes during SW formation [e.g., 3] can be understood and quantitatively modeled. The Geneisis objective is to obtain elemental and isotopic abundances with pre...
