Genetic diversity is important for developing salt-tolerant rice (Oryza sativa L.) cultivars. Certain Thai rice accessions display salt tolerance at the adult or reproductive stage, but their response to salinity at the seedling stage is unknown.

Extraction of mamao luang (hereafter called mamao) with different solvents and varying solid to liquid (S:L) ratio was conducted to verify its antioxidant activities. Total phenolic content (TPC), total flavonoid content, total monomeric anthocyanin content, and antioxidant activities, namely, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity and ferric reducing antioxidant power (FRAP) of the unrefined extracts, were analyzed. The extraction with 70% acetone and 70% methanol and the S:L ratio of 1:30 seemed to be more appropriate and gave significantly (P < 0.

Article Synopsis
  • Salbutamol (SAL) is a substance harmful to human health and is banned as a growth promoter in livestock, prompting the need for its detection in meat and urine.
  • Researchers developed a competitive paper-based colorimetric immunoassay (PCI) using an Ag PO /Ag nanocomposite, which simplifies and cheapens the detection process while being sensitive and specific for SAL.
  • This new method is easy to fabricate with low-cost materials and requires only small amounts of samples and reagents, making it quicker and more efficient than traditional ELISA tests.

Effects of different oils on physicochemical properties, consumer liking, emotion, and purchase intent of sponge cakes were evaluated. Three healthy oils (extra virgin coconut oil, EVCO; extra virgin olive oil, EVOO; rice bran oil, RBO) compared with butter (the control), were used at 20% (w/w, wheat flour basis) in sponge cake formulations. Five positive (calm, good, happy, pleased, satisfied) and 3 negative (guilty, unsafe, worried) emotion terms, selected from the EsSense Profile(®) with slight modification using an online (N = 234) check-all-that-apply questionnaire, were used for consumer testing.

Improvement of Fish Sauce Quality by Strain CMC5-3-1: A Novel Species of Staphylococcus sp.

J Food Sci

September 2015

Food Protein Research Unit, School of Food Technology, Inst. of Agricultural Technology, Suranaree Univ. of Technology, Nakhon Ratchasima, P.O. Box 30000, Thailand.

Staphylococcus sp. CMC5-3-1 and CMS5-7-5 isolated from fermented fish sauce at 3 to 7 mo, respectively, showed different characteristics on protein hydrolysis and volatile formation. These Gram-positive cocci were able to grow in up to 15% NaCl with the optimum at 0.

Fabrication and characterization of novel microneedles made of a polystyrene solution.

J Mech Behav Biomed Mater

October 2015

Dept. of Mechanical Eng., Chulalongkorn Univ., Pathumwan, Bangkok 10330, Thailand. Electronic address:

Nowadays, microneedles are attracting a lot of attention because microneedles can deliver drugs, vaccines and hormones into the body without pain unlike conventional hypodermic needles. Furthermore, microneedles are safe for self-injection and disposal. This work aims to develop novel microneedles made of a solution of polystyrene (PS) in toluene.

Recently, a number of non-beneficial effects of chronic treatment with paracetamol (APAP) have been reported in several systems, including circulatory system. In this study, the effects of acute (1 hour) and chronic (30 days) APAP treatments on cerebral microvessels in a cortical spreading depression (CSD) migraine animal model were investigated. Rats were divided into control, CSD only, and APAP treatment with or without CSD groups.

Effects of 1-methylcyclopropene and hot water quarantine treatment on quality of "Keitt" mangos.

J Food Sci

April 2014

Dept. of Food Technology, Chulalongkorn Univ., Bangkok, Thailand; Dept. of Food Science and Technology, Univ. of California, Davis, CA, U.S.A.

The optimal 1-methylcyclopropene (1-MCP) treatment to slow ripening of whole "Keitt" mangos, either alone or in combination with hot water treatment (HWT) (prior to or post 1-MCP) was identified. USDA-APHIS mandates that HWT can be used for control of fruit flies, but this may affect fruit response to 1-MCP. Mangos were evaluated by repeated measurement of nondestructive firmness, peel color, and ethylene production on the same mango fruits during 2 wk of ripening at 20 °C after treatment.

Tourette syndrome (TS) is characterized by tics, sensorimotor gating deficiencies, and abnormalities of cortico-basal ganglia circuits. A mutation in histidine decarboxylase (Hdc), the key enzyme for the biosynthesis of histamine (HA), has been implicated as a rare genetic cause. Hdc knockout mice exhibited potentiated tic-like stereotypies, recapitulating core phenomenology of TS; these were mitigated by the dopamine (DA) D2 antagonist haloperidol, a proven pharmacotherapy, and by HA infusion into the brain.

Unlabelled: A novel type of environmentally friendly packaging with antibacterial activity was developed from lauric arginate (LAE)-coating of polylactic acid (PLA) films after surface activation using a corona discharge. Scanning electron microscopy (SEM)-based analysis of the LAE/PLA films confirmed the successful coating of LAE on the PLA surface. The mechanical properties of the LAE/PLA films with different levels of LAE-coating (0% to 2.

Article Synopsis
  • The study explored using a Chinese steamed bun starter dough (CSB-SD) to enhance breadmaking by activating lactic acid bacteria and yeast before mixing with wheat flour.
  • Higher levels of activated CSB-SD (10%, 30%, and 50%) negatively impacted dough stability but improved bread volume and softness after storage.
  • Bread made with 30% and 50% activated CSB-SD exhibited better gas generation, gluten structure, and mold resistance compared to the control group.
