On the Synthesis of Graphene Oxide/Titanium Dioxide (GO/TiO) Nanorods and Their Application as Saturable Absorbers for Passive Q-Switched Fiber Lasers.

We report passively Q-switched pulse operation through an erbium-doped fiber laser (EDFL) utilizing graphene oxide/titania (GO/TiO) nanorods as a saturable absorber. The GO/TiO nanorods were fabricated using a Sol-gel-assisted hydrothermal method. The optical and physical characterization of the GO/TiO was then characterized using a field-emission-scanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), and diffuses reflectance spectroscopy (DRS).

EVALUATION OF MODEL FOR END-STAGE LIVER DISEASE SCORE CUT OFF VALUES IN PATIENTS WITH HEPATIC ENCEPHALOPATHY.

Background: Model for End Stage Liver Disease (MELD) is scoring system used for prioritization of patients waiting liver transplantation. Patients with decompensated chronic liver disease (DCLD) with higher MELD score and hepatic encephalopathy (HE) have poor outcome. We planned to note association between short-term mortality and various cut-off values of at admission MELD score in HCV related DCLD patients presenting with HE.

Tissue culture studies on Amaranthus viridis.

Amaranthus viridis is a plant that is very widely distributed in our country, grows easily, and is eaten by low-income groups. It has been found that the proteins of this plant, like most other plants, are deficient in some essential amino acids. We were able to develop cultures from the cut-end parts of this plant tissue.

Gluconeogenesis in the kidney and liver slices of a lizard, Uromastix hardwickii.

1. The liver and kidney of the lizard Uromastix hardwickii have much higher contents of carbohydrate than have been reported for the corresponding rat tissues. Most of this carbohydrate still remains in the tissue even after a long preincubation.
