Understanding the Behavior of Filipino Twitter Users during Disaster

The Philippines is a country that frequentlyexperiences disasters, such as typhoons. During these events,many citizens spread information and communicate with eachother through social media like Twitter. This study aims to takeadvantage of that fact by analyzing the data from social media toget some insights on the situation. Specifically, this paper studiesthe behavior of Filipinos on Twitter during a disaster, and tries tosee the differences between participants, or the direct victims ofthe disaster, and observers. The study used Latent DirichletAllocation and Principal Component Analysis to extract thedifferent topics discussed during a disaster, and found out whichtopics participants are more likely to talk about. Results also showwhich topics are more likely to be retweeted, which languageparticipants in disaster use more often, and what emotions arepresent in the disaster-time tweets of Filipinos

Molecular survey of tick-borne pathogens infecting backyard cattle and water buffaloes in Quezon Province, Philippines

Tick-borne diseases (TBD) cause enormous losses for farmers. Backyard raising comprises majority of the livestock population in the Philippines, but TBD information in backyard livestock is scarce. In this study, 48 cattle and 114 water buffalo samples from Quezon province, Philippines were molecularly screened for tick-borne pathogens. Anaplasma marginale (16.67%) and hemoplasma (20.99%) were detected in the samples. A. marginale infection (P=0.0001) was significantly higher in cattle, while hemoplasma infection (P=0.011) was significantly higher in water buffaloes. A. marginale isolates from this study were highly similar to previous isolates from the Philippines while Mycoplasma wenyonii and Candidatus Mycoplasma haemobos were the identified hemoplasma species. Our findings reveal additional information on the TBD situation of Philippine backyard livestock

Antispasmodic Effect of <i>Valeriana pilosa</i> Root Essential Oil and Potential Mechanisms of Action: Ex Vivo and In Silico Studies

Infusions of Valeriana pilosa are commonly used in Peruvian folk medicine for treating gastrointestinal disorders. This study aimed to investigate the spasmolytic and antispasmodic effects of Valeriana pilosa essential oil (VPEO) on rat ileum. The basal tone of ileal sections decreased in response to accumulative concentrations of VPEO. Moreover, ileal sections precontracted with acetylcholine (ACh), potassium chloride (KCl), or barium chloride (BaCl2) were relaxed in response to VPEO by a mechanism that depended on atropine, hyoscine butylbromide, solifenacin, and verapamil, but not glibenclamide. The results showed that VPEO produced a relaxant effect by inhibiting muscarinic receptors and blocking calcium channels, with no apparent effect on the opening of potassium channels. In addition, molecular docking was employed to evaluate VPEO constituents that could inhibit intestinal contractile activity. The study showed that α-cubebene, β-patchoulene, β-bourbonene, β-caryophyllene, α-guaiene, γ-muurolene, valencene, eremophyllene, and δ-cadinene displayed the highest docking scores on muscarinic acetylcholine receptors and voltage-gated calcium channels, which may antagonize M2 and/or M3 muscarinic acetylcholine receptors and block voltage-gated calcium channels. In summary, VPEO has both spasmolytic and antispasmodic effects. It may block muscarinic receptors and calcium channels, thus providing a scientific basis for its traditional use for gastrointestinal disorders
