        Background: A spinal extension and intensive rehabilitation program reduced the symptoms and pain of kyphosis, and improved function. Objects: This study aimed to demonstrate the effect of a spine extension device on the degree of thoracic kyphosis and extension angles, confirm reduction of the kyphosis angle and an increase in flexibility. Methods: Thirteen adults were enrolled in the experiment, using the spine extension device, which was set to passively extend the spine. The angle between the spinous process of the first thoracic vertebra and the spinous process of the twelfth thoracic vertebra was measured by dual inclinometer before and after using the spine extension device. Results: In the static posture, the thoracic kyphosis decreased after using the spine extension device in the thoracic extension posture, and there was a significant difference (p < 0.05); thoracic extension angle increased with statistical significance (p < 0.05). Conclusion: In this study, the thoracic kyphosis angle and thoracic extension angle of the subjects before and after using spine extension device was compared and analyzed, which proved that the spine extension device can effectively improve the mobility of spinal extension.

        The insecticidal activities of 13 Lamiaceae plant oils and their components against adult German cockroaches, Blattella germanica L. (Blattodea: Blattellidae), were evaluated using fumigant and contact bioassay. Among the tested oils, basil, pennyroyal, and spearmint showed the strongest insecticidal activities against adult B. germanica. Insecticidal activity of pennyroyal was 100% against male B. germinica at 1.25 mg concentration in fumigant bioassay. Basil and spearmint revealed 100% and 100% insecticidal activity against male B. germinica at 5 mg concentration, but their activities reduced to 80% and 25% at 2.5 mg concentration, respectively. In contact toxicity bioassy, basil, pennyroyal, and spearmint oils exhibited 100%, 100%, and 98% mortality against female B. germanica at 1 mg/♀, respectively. Among the constituents identified in basil, pennyroyal and spearmint oils, insecticidal activity of pulegone was the strongest against male and female B. germanica.

        We evaluated the larvicidal and nematicidal activities of 48 3-acylbarbituric acids analogues against the Asian tigermosquito, Aedes albopictus and the pine wood nematode, Bursaphelenchus xylophilus, organisms of increasing global concern.Among 48 3-acylbarbituric acids analogues, four compounds 10, 14d, 14g, and 19b showed >90% larvicidal activity againstAe. albopictus at 10μg/mL concentration, and one (compound 10) showed the strongest larvicidal activity against Ae. albopictus,with a LC50 value of 0.22μg/mL. Only compound 18 showed strong nematicidal activity against pine wood nematode.Most active compounds possessed similar physicochemical properties; thus, actives typically had ClogP values of around1.40-1.50 and rel-PSA values of 16-17%.

        We evaluated the larvicidal activity of 12 Apiaceae plant essential oils and their components against the Asian tiger mosquito, Aedes albopictus, and the inhibition of acetylcholine esterase with their components. Of the 12 plant essential oils tested, ajowan (Trachyspermum ammi), caraway seed (Carum carvi), carrot seed (Daucus carota), celery (Apium graveolens), cumin (Cuminum cyminum), dill (Anethum graveolens), and parsley (Petroselinum sativum) resulted in >90% larval mortality when used at 0.1 mg/mL. Of the compounds identified, α-phellandrene, α-terpinene, p-cymene, (-)-limonene, (+)-limonene, γ-terpinene, cuminaldehyde, neral, (S)-+-carvone, trans-anethole, thymol, carvacrol, myristicin, apiol, and carotol resulted in >80% larval mortality when used at 0.1 mg/mL.

        Precise, rapid and simple methods for species identification in animals are among the most important techniques in the livestock industry and research fields including meat classification. In this study, polymerase chain reaction (PCR) based molecular identification using inter species polymorphisms were examined by PCR-restriction fragment length polymorphism (RFLP) analysis for mitochondrial DNA (mtDNA) cytochrome b (CYTB) gene sequences among four mammalian livestock animals (cattle, horse, goat and pig). The results from PCR-RFLP analysis using the AluI restriction enzyme were also provided for the species-specific band patterns among CYTB gene sequences in these four species. The AluI-digestion for CYTB genes provided interesting migration patterns differentially displayed according to each species. Cattle and horse had one AluI-recognition site at different nucleotide positions and their AluI-digested fragments showed different band patterns on the gels. Pig had two AluI-recognition sites within the amplified CYTB sequences and produced three bands on the gels. Goat had no AluI-recognition site and was located at the same position as the uncut PCR product. The results showed the species-specific band patterns on a single gel among the four livestock animal species by AluI-RFLP. In addition, the results from blind tests for the meat samples collected from providers without any records showed the identical information on the species recorded by observing their phenotypes before slaughter. The application of this PCR-RFLP method can be useful and provide rapid, simple, and clear information regarding species identification for various tissue samples originating from tested livestock species.

        The larvicidal activity of 12 Apiaceae essential oils and their constituents was evaluated against third instar larvae of mosquitoes, Aedes albopictus. Of the 12 Apiaceae essential oils, Dill (Anethum graveolens), Caraway seed (Carum carvi), Cumin (Cuminum cyminum), Carrot seed (Daucus carota), Parsley (Petroselinum sativum) and Ajowan (Trachyspermum ammi) oils at 0.1 mg/ml exhibited 90% larval mortality after 2 days. Analysis by gas chromatography-mass spectrometry led to identification of 8, 3, 13, 12 compounds, respectively. in the oils of Dill (Anethum graveolens), Caraway seed (Carum carvi), Cumin (Cuminum cyminum), Ajowan (Trachyspermum ammi). The compounds thus identified were tested individually for their larvicidal activities against Aedes albopictus. At this same concentration, the individual constituents tested, α-phellandrene, α-Terpinene, ρ -cymene, (+)-Limonene, γ-Terpinene, Thymol, Carvacrol resulted in 100% mortality after 2 days. At this same concentration, the individual constituents tested, (+)-carvone, cuminaldehyde, neral, trans-anethole resulted in 80% mortality after 2 days.
