(2001)1. The gating kinetics and functions of low threshold T-type current in cultured chromaffin cells from rats of 19-20 days gestation (E19-E20) were studied using the patch clamp technique. Exocytosis induced by calcium ...
-
(1998)Guanine N-7 methylation is an essential step in the formation of the m7GpppN cap structure that is characteristic of eukaryotic mRNA 5' ends. The terminal 7-methylguanosine is recognized by cap-binding proteins that ...
-
(1998)A cDNA (MnP13-1) and the Cs-mnp1 gene encoding for an isoenzyme of manganese peroxidase (MnP) from C. subvermispora were isolated separately and sequenced. The cDNA, identified in a library constructed in the vector Lambda ...
-
(1998)We studied the effects of the nitric oxide (NO) synthase inhibitor, Nω- nitro-L-arginine methyl ester (L-NAME), and the NO donor, sodium nitroprusside (SNP) on cat chemosensory responses to intravenous injections of NaCN ...
-
(1998)Penetration of light into the pregnant sheep uterus was studied in 9 ewes, gestational ages 40 to 142 days (term 147 days). Light Sensors were placed inside the pregnant horn and over the flank skin overlying the position ...
-
(1998)Objective: Previous studies have shown small bowel motor activity abnormalities in patients with liver cirrhosis of different etiologies, but motility has not been studied in patients with primary biliary cirrhosis. Our ...
-
(American Physiological Society, 1998)We investigated the neurovascular mechanisms that determine the flare response to intradermal capsaicin injection in humans and delineated the associated areas of mechanical and heat hyperalgesia. The flare response was ...
-
(Lippincott Williams and Wilkins, 1998)Background - Myocardial ischemic preconditioning is a well-known phenomenon, however there is scant information in regard to nonischemic preconditioning. Methods and Results - We studied in anesthetized dogs the preconditioning ...

(Blackwell Publishing Ltd, 1998)Tramadol is a widely-used analgesic for pre- and post-operative pain which has a different pharmacological profile to that of classical opioids, since it does not induce respiratory depression, constipation, sedation, ...
-
(Brazilian Journal of Genetics, 1998)In order to investigate the association between ABO blood groups and serum haptoglobin (Hp), we typed Hp and ABO blood groups in 288 children, who were selected at random among those who began their primary school in 1973 ...
-
(1998)The distribution of prostaglandin-E2 (PGE2) and prostaglandin-F(2α) (PGF(2α)) was studied in subcellular fractions isolated from homogenates of human atrial fresh tissue by differential centrifugation. Right and left atrial ...
-
(1998)Ecological and health problems posed by microalgal blooms (red tides) occurring in the Southern part of Chile are reviewed. Out of the six human illnesses provoked by microalgal toxins, paralytic shellfish poisoning is the ...
-
(1998)Background: Inherited susceptibility to type 1 diabetes is partially determined by HLA genes. HLA-DQA1 and DQB1 alleles have been chosen as the most sensitive susceptibility markers. Family studies are a good method to ...
-
(1998)Background: Fragile X syndrome is the most important cause of sex linked mental retardation and the second of chromosomal origin, after Down syndrome. Aim: To apply the modified Hagerman score to patients with mental ...
-
(1997)Purpose: To identify and characterize astrocyte responses and reactivation in human optic nerve heads from patients with primary open-angle glaucoma. Methods: Fifteen optic nerve heads with primary open-angle glaucoma and ...
-
(1998)Protein kinase CK2 is a ubiquitous eukaryotic ser/thr protein kinase. The active holoenzyme is a heterotetrameric protein corn posed of catalytic (α and α') and regulatory (β) subunits that phosphorylates many different ...
