Thomas L, Rocafull M, Del Castillo J
Biomed Res Int . 2013 Mar; 2013:698674. PMID: 23484143
Transepithelial sodium transport is a process that involves active Na(+) transport at the basolateral membrane of the epithelial cell. This process is mediated by the Na(+)/K(+) pump, which exchanges 3...

Barrera G, Portillo R, Mijares A, Rocafull M, Del Castillo J, Thomas L
Immunol Lett . 2009 May; 123(1):52-9. PMID: 19428552
Secretory antibodies of the immunoglobulin A (sIgA) class constitute the first line of antigen-specific immune protection against pathogens and other antigens at mucosal surfaces. Although initially perceived as potentially deleterious,...

Del Castillo J, Burguillos L
J Membr Biol . 2005 Oct; 205(1):37-47. PMID: 16245041
K+ -conductive pathways were evaluated in isolated surface and crypt colonic cells, by measuring (86)Rb efflux. In crypt cells, basal K+ efflux (rate constant: 0.24 +/- 0.044 min(-1), span: 24...

Garcia-Amado M, Del Castillo J, Eglee Perez M, Dominguez-Bello M
Poult Sci . 2005 Jun; 84(6):947-50. PMID: 15971535
The mechanisms involved in D-glucose and amino acid transport in the intestine of birds are still not clear. In chickens, D-glucose and amino acid absorption occurs via carrier-mediated transport, but...

Cariani L, Thomas L, Brito J, Del Castillo J
Anal Biochem . 2003 Dec; 324(1):79-83. PMID: 14654048
This paper describes a rapid and sensitive method to determine inorganic phosphate, even in the presence of labile organic phosphate compounds and large quantities of proteins. The method eliminates the...

Reig I, Sanchis J, Planelles R, Del Castillo J
Eur J Surg . 2001 Mar; 167(2):142-5. PMID: 11266256
Objective: To investigate the carcinogenic role of suture materials in an experimental model in rats. Design: Laboratory, experimental study. Setting: University hospital, Spain. Subjects: 125 Sprague-Dawley rats in 5 groups...

Del Castillo J, Arevalo J, Burguillos L
Am J Physiol . 1999 Sep; 277(3):G563-71. PMID: 10484381
Epinephrine and beta-adrenergic agonists (beta1 and beta2 for isoproterenol, beta1 for dobutamine, beta2 for salbutamol) stimulated K+ (or 86Rb) influx mediated by the Na+-K+-2Cl- cotransporter and the Na+-K+ pump in...

Del Castillo J, Sepulveda F
Gastroenterology . 1995 Aug; 109(2):387-96. PMID: 7615187
Background & Aims: K+ secretion is believed to require the presence of a basolateral Na+/K+/2Cl- cotransporter. The aim of this study was to identify this transport system in epithelial cells...

Del Castillo J, Burguillos L
Am J Physiol . 1994 Jun; 266(6 Pt 1):G1083-9. PMID: 8023940
K+ transport mechanisms in epithelial cells isolated from guinea pig distal colon have been studied using 86Rb as a tracer. A transport pathway has been identified that is proposed to...

Muniz R, Burguillo L, Del Castillo J
Pflugers Arch . 1993 Apr; 423(1-2):59-66. PMID: 8488093
The effects of starvation on neutral amino acid transport were examined in isolated enterocytes. Starvation stimulated L-alanine transport by the Na(+)-dependent system A and the Na(+)-independent system L without producing...
