Synthesis of Hydroxyapatite with Antibacterial Properties Using a Microwave-Assisted Combustion Method.

The prevention of implant-associated infections has been increasing clinically in orthopedic surgery. Hydroxyapatite with antibacterial properties was synthesized using a microwave-assisted combustion method. High crystallinity at low temperature can be achieved using this method.

Molecular cloning and characterization of a novel bi-functional α-amylase/subtilisin inhibitor from Hevea brasiliensis.

A novel cDNA encoding a bi-functional α-amylase/subtilisin inhibitor (HbASI) was isolated from rubber (Hevea brasiliensis) leaves cultivar RRIM600. The HbASI had strong homology with the soybean trypsin inhibitor (Kunitz) family of protease inhibitors. Its putative amino acid sequence was similar to that of the α-amylase/subtilisin inhibitor from Ricinus communis (72% identity).

RNA Polymerase II Second Largest Subunit Molecular Identification of Boletus griseipurpureus Corner From Thailand and Antibacterial Activity of Basidiocarp Extracts.

Background: Boletus griseipurpureus Corner, an edible mushroom, is a putative ectomycorrhizal fungus. Currently, the taxonomic boundary of this mushroom is unclear and its bitter taste makes it interesting for evaluating its antibacterial properties.

Objectives: The purpose of this study was to identify the genetic variation of this mushroom and also to evaluate any antibacterial activities.

Trichoharzianol, a new antifungal from Trichoderma harzianum F031.

A new decalin derivative, trichoharzianol (1), together with three known compounds, eujavanicol A (2), 5-hydroxy-3-hydroxymethyl-2-methyl-7-methoxychromone (3), and 4,6-dihydroxy-5-methylphthalide (4), were isolated from Trichoderma harzianum F031. For the first time, compounds 2-4 were reported from the Trichoderma species. Their structures were characterized by spectroscopic methods.

Molecular cloning and biochemical characterization of a novel cystatin from Hevea rubber latex.

A novel cDNA encoding a cysteine proteinase inhibitor or phytocystatin was isolated from Hevea brasiliensis RRIM600 rubber latex cDNA library. The full-length HbCPI obtained from rapid amplification of cDNA ends contains 588 bp. An open reading frame of 306 bp encodes for a protein of 101 amino acids with the typical inhibitory motifs of phytocystatin superfamily, namely the central signature motif QXVXG, a GG doublet and LARFAV-like motifs in the N-terminal part, and conserved A/PW residues in the C-terminal region.

Myxobolus supamattayai n. sp. (Myxosporea: Myxobolidae) from Thailand parasitizing the scale pellicle of wild mullet (Valamugil seheli).

A new myxosporean species, Myxobolus supamattayai n. sp., was isolated from wild mullet (Valamugil seheli) from the Andaman Sea, Thailand and described based on its morphology and molecular data.

Molecular cloning and expression of a mammalian homologue of a translationally controlled tumor protein (TCTP) gene from Penaeus monodon shrimp.

White spot syndrome, caused by white spot syndrome virus (WSSV), is a deadly disease of shrimps, causing a catastrophic loss in shrimp industries worldwide. In order to investigate molecular response of shrimp haemocyte to WSSV infection, we performed subtraction hybridization of mRNAs from healthy and WSSV-infected haemocyte. One of the genes that were severely down-regulated in moribund WSSV-infected-haemocyte was translationally controlled tumor protein (TCTP) (or fortilin).

A syntenin-like protein with postsynaptic density protein (PDZ) domains produced by black tiger shrimp Penaeus monodon in response to white spot syndrome virus infection.

We report the isolation and characterization of products from a subtractive cDNA library from the haemolymph of Penaeus monodon experimentally infected with white spot syndrome virus (WSSV). One cDNA derived from up-regulated mRNA was identified. A homology search indicated similarity to the putative protein syntenin (TE8).
