Germinated brown rice (GBR) flour (0%, 25%, 50%, 75% and 100%) was added to brown rice (BR) and white rice (WR) flours and the densities of pound cake batters, morphology, color value, textural properties, sensory preference test, and hardness during storage were investigated, in order to develop health functional gluten-free rice pound cakes with high nutritional value. The rice was milled with the newly developed rice milling method. The entire shape and cross section of all cakes were symmetrical and desirable. The density of pound cake batter and weight of cake increased with addition of increasing GBR. Specific volume was not significantly different (2.1-2.4 mL/g). Textural properties of cakes between WR-GBR and BR-GBR showed different trends with adding GBR. On the sensory test, overall quality of rice pound cake did not significantly differ between rice flour types. Hardness of rice pound cakes and brittleness decreased with increasing addition of GBR flour. The hardness and the peak intensity at $2{\theta}=17^{\circ}$ decreased with increasing addition of GBR. The results, that addition of GBR flour improved the nutrition value and functionality of gluten free rice pound cakes and prevented staling of rice pound cakes during storage.

Sexual addiction is accompanied with anxiety, psychological and physical dependence. Also, sexual addict want to make their presence through sexual adventures and seem sexually obsessed. In this study, we examined the changes of brain activity related to sexual addiction by utilizing the developed multi-sensory therapy after 4-weeks sex offender treatment program. We analyzed the electroencephalogram (EEG) activity changes in the subjects and regions of brain. As a result, the theta wave significantly increased after treatment than before (p < 0.001). The absolute alpha wave was increased whereas the relative alpha waves were decrease significantly (p < 0.001). The results could conclude that multi-sensory therapy on sex offender shows more stable status against sexual stimulations. Moreover, the reduction of the relative alpha waves in parietal lobe of sex offender is correlated to the less attention on sexual stimulations. The multi-sensory therapy not only provides a neurobiological explanation, but also can be used for clinical implications, i.e. prevention and treatments, for sex addiction.

Listeria monocytogenes is an important foodborne pathogen that comprises four genetic lineages: I, II, III, and IV. Of these, lineage II is frequently recovered from foods and environments and responsible for the increasing incidence of human listeriosis. In this study, the phylogenetic structure of lineage II was determined through sequencing analysis of the ascB-dapE internalin cluster. Fifteen sequence types proposed by multilocus sequence typing based on nine housekeeping genes were grouped into three distinct sublineages, IIA, IIB, and IIC. Organization of the ascB-dapE internalin cluster could serve as a molecular marker for these sublineages, with inlGHE, inlGC2DE, and inlC2DE for IIA, IIB, and IIC, respectively. These sublineages displayed specific genetic and phenotypic characteristics. IIA and IIC showed a higher frequency of recombination (${\rho}/{\theta}$). However, recombination events had greater effect (r/m) on IIB, leading to its high nucleotide diversity. Moreover, IIA and IIB harbored a wider range of internalin and stress-response genes, and possessed higher nisin tolerance, whereas IIC contained the largest portion of low-virulent strains owing to premature stop codons in inlA. The results of this study indicate that IIA, IIB, and IIC might occupy different ecological niches, and IIB might have a better adaptation to a broad range of environmental niches.

L-theanine is a unique amino acid, found almost solely in tea plants. It is the main component responsible for the exotic taste of green tea. In our studies of L-theanine, we have found a variety of biological activities including relaxation and the alleviation of PMS. In general, animals generate very weak electric pulses on the surface of the brain, called brain waves. Brain waves are classified into four types, namely $\alpha$, $\beta$, $\delta$ and $\theta$-waves, based on their frequency. Brain waves correlate with individual mental conditions. For example, generation of $\alpha$-waves is considered an index of relaxation. In human volunteers, $\alpha$-waves were generated on the occipital and parietal regions of the brain surface within 40 minutes after the oral administration of 50 or 200 mg Suntheanine$^{TM}$ without causing drowsiness. Premenstrual Syndrome (PMS) is a symptom unique to women which appears in the luteal phase from the ovulation period through the first day of menstruation. It possesses characteristics of having a peak just prior to menstruation and disappearing 1 - 2 days following the start of menstruation. Symptoms of PMS are generally categorized as mental, physical and social symptoms. When comparing the reported Symptoms of PMS by the methods of MDQ score, the Suntheanine$^{TM}$ group was found to have a lower incidence of PMS symptoms, including physical, mental and social symptoms. Overall, a significant alleviation of PMS symptoms by the administration of 200 mg Suntheanine$^{TM}$ was observed. With the successful industrial production of L-theanine, we are now able to supply Suntheanine$^{TM}$, offering a tremendous opportunity for designing functional foods targeting relaxation and the alleviation of PMS.

The present investigation was conducted to evaluate the regulation of sleep architecture by the red ginseng water extract (RGE) in acutely and chronically restraint stressed rats. Adult rats were fitted with sleep.wake recording electrodes. Following post-surgical recovery, rats were extensively habituated for freely moving polygraphic recording conditions. Polygraphic signs of sleep-wake activities were recorded for 24 h after RGE administration and induction of stress and were analyzed to understand the regulation of sleep architecture. Acute stress decreased wakefulness and increased total sleep, non-rapid eye movement (NREM) sleep, and rapid eye movement (REM) sleep in both the daytime and nighttime recording. RGE shortened the daytime NREM and REM sleep, without changing the wakefulness and total sleep. RGE increased nighttime wakefulness, and decreased total, NREM and REM sleep. Chronic stress increased wakefulness and decreased total sleep in the daytime recording, and increased REM and decreased NREM sleep in both the day and night time recording. RGE ameliorated chronic stress and induced alterations of REM and NREM sleep in the day and night time sleep architecture. Acute and chronic stress could also induce alternations in cortex electroencephalogram (EEG) recording during NREM, REM sleep and wakefulness. These findings suggest that RGE may modulate the sleep behavior in acutely and chronically stressed rats and the ameliorating effect of RGE on the sleep architecture may involve in modulation of $\alpha$-, $\theta$- and $\delta$- wave activities of the cortical EEG.
