A 34-year-old woman with schizophrenia developed abdominal pain. Ultrasound demonstrated cholelithiasis and a dilated biliary tree. The patient underwent endoscopic retrograde cholangiopancreatography (ERCP), sphincterotomy, and extraction of gallstones from the common bile duct. She developed post-procedure fever, tachycardia, and...

BACKGROUND: The fresh leaves of Eucalyptus globulus Labill. (Lan An) have been used in Chinese medicine for many years to treat dermatomycosis. Macrocarpal C was isolated from this herb and identified as its major antifungal component by bioassay-guided purification....

Convergence analyses on on-line weight noise injection-based training algorithms for MLPs.

IEEE transactions on neural networks and learning systems

IEEE Trans Neural Netw Learn Syst. 2012 Nov;23(11):1827-40. doi: 10.1109/TNNLS.2012.2210243.

Injecting weight noise during training is a simple technique that has been proposed for almost two decades. However, little is known about its convergence behavior. This paper studies the convergence of two weight noise injection-based training algorithms, multiplicative weight...

Screening neonatal jaundice based on the sclera color of the eye using digital photography.

Biomedical optics express

Leung TS, Kapur K, Guilliam A, Okell J, Lim B, MacDonald LW, Meek J.
PMID: 26601015
Biomed Opt Express. 2015 Oct 23;6(11):4529-38. doi: 10.1364/BOE.6.004529. eCollection 2015 Nov 01.

A new screening technique for neonatal jaundice is proposed exploiting the yellow discoloration in the sclera. It involves taking digital photographs of newborn infants' eyes (n = 110) and processing the pixel colour values of the sclera to predict...

Enantioselective phospha-Michael addition of diarylphosphines to β,γ-unsaturated α-ketoesters and amides.

Chemical communications (Cambridge, England)

Chew RJ, Teo KY, Huang Y, Li BB, Li Y, Pullarkat SA, Leung PH.
PMID: 24968261
Chem Commun (Camb). 2014 Aug 14;50(63):8768-70. doi: 10.1039/c4cc01610f. Epub 2014 Jun 26.

An enantioselective hydrophosphination of β,γ-unsaturated α-ketoesters and amides has been developed using a chiral palladacycle catalyst. Adducts can be obtained in excellent yields and enantioselectivities, providing direct access to chiral tertiary phosphines which are synthetically useful intermediates in the...

BACKGROUND: Chromosomal microarray offers superior sensitivity for identification of submicroscopic copy number variants (CNV) and it is advocated to be the first tier genetic testing for patients with autism spectrum disorder (ASD). In this regard, diagnostic yield of array...

Endogenous Antigen Presentation of MHC Class II Epitopes through Non-Autophagic Pathways.

Frontiers in immunology

Leung CS.
PMID: 26441969
Front Immunol. 2015 Sep 09;6:464. doi: 10.3389/fimmu.2015.00464. eCollection 2015.

Antigenic peptides presented by major histocompatibility complex (MHC) class II molecules are generally derived from exogenous proteins acquired by antigen presenting cells. However, in some circumstances, MHC class II molecules can present intracellular proteins expressed within the antigen-presenting cells....
