Newly diagnosed acromegaly presenting with hypertriglyceridemic pancreatitis with normal amylase and lipase levels.

Proceedings (Baylor University. Medical Center)

Sotello D, Rivas AM, Nugent KM.
PMID: 24381394
Proc (Bayl Univ Med Cent). 2014 Jan;27(1):16-8. doi: 10.1080/08998280.2014.11929038.

The incidence of hypertriglyceridemia in acromegaly is three times higher than in the normal population, and it is the most common dyslipidemia in acromegaly. We present a case of hypertriglyceridemic pancreatitis confirmed by imaging, with normal pancreatic enzymes. Hypertriglyceridemia...

Enzymatic biosensor for the electrochemical detection of 2,4-dinitrotoluene biodegradation derivatives.

Talanta

Rodríguez MC, Monti MR, Argaraña CE, Rivas GA.
PMID: 18970513
Talanta. 2006 Feb 28;68(5):1671-6. doi: 10.1016/j.talanta.2005.08.032. Epub 2005 Sep 28.

In this work, we demonstrate for the first time that 4-methyl-5-nitrocatechol (4M5NC) and 2,4,5-trihydroxytoluene (2,4,5-THT), two compounds obtained from the 2,4-DNT biodegradation are recognized by polyphenol oxidase as substrates. An amperometric biosensor is described for detecting these compounds and...

Glucose biosensors based on the immobilization of copper oxide and glucose oxidase within a carbon paste matrix.

Talanta

Luque GL, Rodríguez MC, Rivas GA.
PMID: 18970008
Talanta. 2005 Apr 15;66(2):467-71. doi: 10.1016/j.talanta.2004.07.019. Epub 2005 Apr 07.

The performance of amperometric glucose biosensors based on the dispersion of glucose oxidase (GOx) and copper oxide within a classical carbon (graphite) paste composite is reported in this work. Copper oxide promotes an excellent electrocatalytic activity towards the oxidation...

Nanotube nucleation versus carbon-catalyst adhesion--probed by molecular dynamics simulations.

The Journal of chemical physics

Ribas MA, Ding F, Balbuena PB, Yakobson BI.
PMID: 20001051
J Chem Phys. 2009 Dec 14;131(22):224501. doi: 10.1063/1.3266947.

Catalytic nucleation of carbon nanotubes (CNTs) remains a challenge for the theory: Which factors and forces decide if the gathering sp(2)-network of atoms will adhere to the catalyst particle and fully cover it or the graphitic cap will liberate...

Prediction of skin cancer occurrence by ultraviolet solar index.

Oncology letters

Rivas M, Rojas E, Calaf GM.
PMID: 22741013
Oncol Lett. 2012 Apr 01;3(4):893-896. doi: 10.3892/ol.2012.580. Epub 2012 Jan 24.

An increase in the amount of solar ultraviolet light that reaches the Earth is considered to be responsible for the worldwide increase in skin cancer. It has been reported that exposure to excessive levels of solar ultraviolet light has...

High density lipoprotein/sphingosine-1-phosphate-induced cardioprotection: Role of STAT3 as part of the SAFE pathway.

JAK-STAT

Frias MA, Lecour S, James RW, Pedretti S.
PMID: 24058758
JAKSTAT. 2012 Apr 01;1(2):92-100. doi: 10.4161/jkst.19754.

High density lipoprotein (HDL) cholesterol has beneficial effects beyond its atheroprotective function in reverse cholesterol transport, including cardioprotection against ischemia reperfusion (IR) injuries. Two major constituents of HDL, namely the structural protein apolipoprotein AI (apoAI) and the sphingolipid sphingosine-1-phosphate...

Pneumocephalus as a Complication of Transsphenoidal Surgery for Pituitary Adenoma: A Case Report.

Cureus

Thavaraputta S, Attaya EN, Lado-Abeal J, Rivas AM.
PMID: 30338180
Cureus. 2018 Aug 05;10(8):e3104. doi: 10.7759/cureus.3104.

Pneumocephalus (PNC) is a rare complication of transsphenoidal surgery that can result from cerebrospinal fluid (CSF) leak, allowing air entry into the CSF. We report the case of a 49-year-old female patient who presented to the emergency department three...
