(17) In contrast with oligodendrocytes, [Cl-]i in astrocytes is significantly increased (from 20 to 40 mM) above the equilibrium distribution owing to the activity of an inward directed Cl- pump; this suggests a different mechanism of K+ uptake in these cells.
(18) In contrast, the ryanodine receptor is observed in dendritic shafts, but not in the spines.
(19) In contrast sham-hemodialysis in group CA and group PS, respectively, did not result in significant increases in amino acid efflux from the leg implying that the protein catabolic effect of blood membrane contact depends on the chemical properties of dialysis membranes.
(20) In contrast, the association of serum cholesterol with mortality due to causes other than coronary heart disease changed during follow-up (interaction of cholesterol with follow-up period: p = 0.004).
(adv.) At which place; where.
(conj.) Considering that; it being the case that; since; -- used to introduce a preamble which is the basis of declarations, affirmations, commands, requests, or like, that follow.
(conj.) When in fact; while on the contrary; the case being in truth that; although; -- implying opposition to something that precedes; or implying recognition of facts, sometimes followed by a different statement, and sometimes by inferences or something consequent.
(1) This trend appeared to reverse itself in the low dose animals after 3 hr, whereas in the high dose group, cardiac output continued to decline.
(2) Patients with papillary carcinoma with a good cell-mediated immune response occurred with much lower infiltration of the tumor boundary with lymphocyte whereas the follicular carcinoma less cell-mediated immunity was associated with dense lymphocytic infiltration, suggesting the biological relevance of lymphocytic infiltration may be different for the two histologic variants.
(3) There was appreciable variation in toothbrush wear among subjects, some reducing their brush to a poor state in 2 weeks whereas with others the brush was rated as "good" after 10 weeks.
(4) The most actively proliferating region of the excurrent duct system is zone 3 of the epididymis, whereas the least active region is the ductuli efferentes.
(5) The newborn with critical AS typically presents with severe cardiac failure and the infant with moderate failure, whereas children may be asymptomatic.
(6) F(420) is photolabile aerobically in neutral and basic solutions, whereas the acid-stable chromophore is not photolabile under these conditions.
(7) Application of 40 microM NiCl2 reversibly blocked It while leaving Is intact, whereas 20 microM CdCl2 reversibly blocked Is, but not It.
(8) When micF was cloned into a high-copy-number plasmid it repressed ompF gene expression, whereas when cloned into a low-copy-number plasmid it did not.
(9) Ethanol and L-ethionine induce acute steatosis without necrosis, whereas azaserine, carbon tetrachloride, and D-galactosamine are known to produce steatosis with varying degrees of hepatic necrosis.
(10) Whereas strain Ga-1 was practically avirulent for mice, strain KL-1 produced death by 21 days in 50% of the mice inoculated.
(11) Eighty-two per cent of patients with falciparum malaria had recently returned from Africa whereas 82% with vivax malaria had visited Asia.
(12) The results indicate that OA-bearing macrophages primed T cells and generated helper T cells, whereas the culture of normal lymphocytes with soluble OA in the absence of macrophages generated suppressor T cells.
(13) After midazolam infusion, there was a 50% decrease in amplitude of P3 in response to target tones (P less than 0.006), whereas N3 latency increased by 40 ms (P less than 0.05).

(16) Peak Expiratory Flow and Forced Expiratory Mean Flows in the ranges 0-25%, 25-50% and 50-75% of Forced Vital Capacity were significantly reduced in animals exposed to gasoline exhaust fumes, whereas the group exposed to ethanol exhaust fumes did not differ from the control group.
(17) When the eye was dissected into anterior uveal, scleral, and retinal complexes, prostaglandin D2 was formed in the highest degree in all the complexes, whereas prostaglandin E2 and F2 alpha formation was specific to given ocular regions.
(18) This mAb inhibited monocyte binding of both soluble FITC-labeled IgA and IgA-coated E, whereas it did not inhibit IgG binding.
