Enhanced extraction of bioactive compounds from propolis (Apis mellifera L.) using subcritical water.

The bioactive compounds and antioxidant activities of propolis extracts were investigated using subcritical water extraction (SWE). SWE was performed by varying temperature (110-200 °C) and time (10-30 min). SWE using only water as solvent successfully to extracted bioactive compounds from propolis using high-purity glass thimbles.

Development of a pH indicator for monitoring the freshness of minced pork using a cellulose nanofiber.

A cellulose nanofiber (CNF)-based pH-sensitive indicator was developed by mixing CNF with red radish color extract (RRCE) to analyze the freshness of minced pork. Among various mixing conditions of RRCE solutions (0.4-1.

Percentile Distributions of Birth Weight according to Gestational Ages in Korea (2010-2012).

The Pediatric Growth Chart (2007) is used as a standard reference to evaluate weight and height percentiles of Korean children and adolescents. Although several previous studies provided a useful reference range of newborn birth weight (BW) by gestational age (GA), the BW reference analyzed by sex and plurality is not currently available. Therefore, we aimed to establish a national reference range of neonatal BW percentiles considering GA, sex, and plurality of newborns in Korea.

[The Relationship between High Sensitivity C-Reactive Protein and Metabolic Syndrome according to the Fasting Glucose Level at Medical Checkups.].

Background: This study was performed to investigate the difference in high sensitivity C-reactive protein (hsCRP) and metabolic syndrome according to the fasting glucose level, especially between the groups of less than 100 mg/dL and 100-109 mg/dL, which were conventionally categorized into normal levels.

Methods: Those who underwent routine medical checkups aged above 20 (male, 3,221; female, 3,334) at a Health Promotion Center (Seoul, Korea) were divided into normal fasting glucose group I (glucose <100 mg/dL), normal fasting glucose group II (glucose, 100-109 mg/dL), impaired fasting glucose group, and diabetes mellitus group. The hsCRP, obesity index, blood pressure, total cholesterol, triglyceride, high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and lipoprotein(a) [Lp(a)] were compared among the groups.

A mouse model system for genetic analysis of sociability: C57BL/6J versus BALB/cJ inbred mouse strains.

Background: Impairments in social behaviors are highly disabling symptoms of autism, schizophrenia, and other psychiatric disorders. Mouse model systems are useful for identifying the many genes and environmental factors likely to affect complex behaviors, such as sociability (the tendency to seek social interaction). To progress toward developing such a model system, we tested the hypothesis that C57BL/6J inbred mice show higher levels of sociability than BALB/cJ inbred mice.
