Integration of genomic-based surveillance in the National Rabies Control Program provides additional insights into rabies virus (RABV) evolution and transmission dynamics and can, therefore, inform public health decisions. This pilot study used the previously reported 49 RABV sequences in Davao City and some neighboring provinces to evaluate the utility of targeted sequencing as an inexpensive alternative to whole genome sequencing. We applied different tree distance metrics to compare RABV whole genome (WG) and individual RABV genes. Phylogenetic trees reconstructed using IQTree2 and BEAST were used to compare differences in phylogenetic signals, tree topology, and evolutionary patterns. There were no significant differences in the phylogenetic signals of the three major clades in the trees, with strong support values for sampling variance and underlying variances at the gene and site levels. A comparison of the Bayesian phylogenetic tree of WG and individual genes showed that there were no significant differences in the substitution rate and divergence time. Moreover, patristic distances (PDs) of all individual gene trees were positively correlated and congruent to the RABV WG of identical strains, with correlation values above 99%, which ruled out the possibility of missing out on relevant findings on evolutionary dynamics using only individual genes. Based on the results of our detailed genetic analyses, RNA-dependent RNA polymerase (L) and phosphoprotein (P) segments were identified as the best biomarkers to investigate the evolutionary analysis of locally circulating RABV variants in Davao City due to the close PDs of their trees relative to the WG. Less expensive options such as gene-based surveillance will enable the local government to trace and monitor the actual genetic diversity and spread of the virus, which could lead to the design and implementation of focused strategies.","PeriodicalId":39096,"journal":{"name":"Philippine Journal of Science","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76098771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With this, the challenges and threats posed to the vulnerable population require targeted interventions. While public health surveillance methods had developed recent advances to meet users’ information needs, the volume and complexity of infectious disease data had increased, resulting in increasing difficulty to facilitate risk communication with the public and for decision-makers to make informed measures to protect the public’s health. Moreover, the implementation of COVID-19 spatiotemporal disease surveillance strategies specifically targeting the vulnerable population in the Davao Region had been previously unexplored. This paper investigated the COVID-19 incidence in the Davao Region from 03 Mar 2020, the earliest recorded date of onset, to 31 Aug 2021 using geospatial tools. The variables were visualized through choropleth maps and graduated symbols, and subsequently examined through spatial autocorrelation and hotspot analysis. Hotspots across the region were observed to be in high-density areas. These areas pose greater risks of infection due to the presence of a high concentration of cases. However, high case fatality rates were found in far-flung municipalities where access to COVID-19 healthcare facilities is a dilemma. In the COVID-19 setting and future disease outbreaks similar to COVID-19, results from this study may provide insights to government offices and other related agencies to improve healthcare systems and programs such as providing and initiating tailor-fitted isolation and consultation mechanisms appropriate to the vulnerable population in a community.","PeriodicalId":39096,"journal":{"name":"Philippine Journal of Science","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85774495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The covariance influences wave packet spreading and the probability current through a given point. This paper shows another effect of the covariance: non-zero covariance can manifest as an asymmetry of the regional momentum density. Consider a selective measurement |𝚿𝚿⟩ → |𝚿𝚿[𝒙𝒙 𝟏𝟏 ,𝒙𝒙 𝟐𝟐 ] ⟩ where the initial state |𝚿𝚿⟩ is projected into the state |𝚿𝚿[𝒙𝒙 𝟏𝟏 ,𝒙𝒙 𝟐𝟐 ] ⟩ within a smaller region 𝒙𝒙𝟏𝟏 < 𝒙𝒙 < 𝒙𝒙𝟐𝟐. The momentum representation of the projected state is 𝚽𝚽[𝒙𝒙 𝟏𝟏 ,𝒙𝒙 𝟐𝟐 ] = ⟨𝒑𝒑|𝚿𝚿[𝒙𝒙 𝟏𝟏 ,𝒙𝒙 𝟐𝟐 ] ⟩ and the corresponding momentum density |𝚽𝚽 [𝒙𝒙 𝟏𝟏 ,𝒙𝒙 𝟐𝟐 ] | 𝟐𝟐 is the regional momentum density. This paper examines a molecule-sized particle under uniform gravity (represented by a Gaussian wave packet 𝚼𝚼𝟎𝟎 ) at the classical turning point. I consider the effect of the covariance of 𝚼𝚼𝟎𝟎 on the regional momentum density in the classically forbidden region. The initial state 𝚼𝚼𝟎𝟎 with a given covariance is projected into the classically forbidden region, producing the state 𝚼𝚼𝑪𝑪𝑪𝑪. If the corresponding momentum wave function is 𝚽𝚽𝑪𝑪𝑪𝑪, the regional momentum density is 𝚷𝚷 𝑪𝑪𝑪𝑪 = |𝚽𝚽𝑪𝑪𝑪𝑪 |𝟐𝟐. I derive an analytic expression for 𝚷𝚷 𝑪𝑪𝑪𝑪 that shows that a non-zero covariance predicts an asymmetric momentum density in the classically forbidden region. This gives us a measure of control in preparing a preferred momentum distribution in the classically forbidden region using the appropriate covariance, at the price of a larger momentum uncertainty due to the uncertainty principle (as the configuration space of the particle is decreased). Also, since the momentum density is obtained experimentally from the statistics of momentum measurements, we can measure the covariance through comparison with the predicted momentum distribution, as well as indirectly test the equivalence principle.","PeriodicalId":39096,"journal":{"name":"Philippine Journal of Science","volume":"123 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85690008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are four secondary outcomes – including carotid-femoral pulse wave velocity (cfPWV), five times sit-to-stand test (FTSST), timed up and go test (TUGT), and quality of life (QOL). After the 8-wk program, the EX significantly improved in all outcomes from baseline (p < 0.001) except TUGT (p = 0.07) and QOL. On the other hand, the environmental domain of QOL significantly decreased (p < 0.05) in the CG from baseline. However, significant differences were found in SBP, DBP, FTSST, and TUGT between the groups except for cfPWV (p = 0.06).

Therefore, there is a mounting urgency to find new sources of clinical candidates for the development of drugs that are effective against drug-resistant infections and cancer. Hot springs and volcanic environments represent valuable sources of novel natural products (NPs) – including polyketides, alkaloids, and peptides – yet largely untapped and understudied. Microbes from these niches have been found to develop unique defenses to thrive in extreme temperatures and harsh conditions, leading to the biosynthesis of novel molecules with unique chemical architectures and remarkable biological activities. The present review surveys the bioactive NPs from hot springs and volcanic microbes from 2006–2022, highlighting their chemical structures and biological potential. Notably, the compounds ohmyungsamycin A, dicitrinone B, and terrein displayed more potent cytotoxic effects on several cancer cell lines compared to the current chemotherapy drugs, indicating a promising potential for drug development. The continued exploration of extreme microbes will undoubtedly bring many discoveries of bioactive molecules potentially valuable for biotechnological or pharmaceutical applications.","PeriodicalId":39096,"journal":{"name":"Philippine Journal of Science","volume":"17 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90779413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential of the by-products as a natural source of bioactive polar and nonpolar compounds suitable for applications in the food, cosmetic and pharmaceutical industries was investigated. Four lavender samples were studied – three by-products from industrial steam distillation (L-SD20 M, L-SD21 M, and L-SD21 Z) and one raw untreated lavender (L-UNTR21 Z) – and their chemical composition and antioxidant capacity were determined and compared. Nine phenolic acids (gallic, protocatehuic, chlorogenic, caffeic, syringic, p-coumaric, ferulic, salicylic, and rosmarinic acids) and five flavonoids [(+)-catechin, (–)-epicatechin, rutin, hesperidin, and quercetin] were detected in the 70% ethanolic extract of L-SD20 M. The highest amount of phenolic compounds at 16.08 ± 0.38 mg gallic acid equivalents/ g dry weight (dw) were found in the L-SD21 Z 70% ethanolic extract. L-SD21 M 70% ethanolic extract was distinctive with the highest amounts of flavonoids at 3.89 ± 0.44 mg quercetin equivalents/ g dw. The antioxidant capacity of the extracts was evaluated by four methods: radical scavenging activity of 2,2 diphenyl-1-picrylhydrazyl (DPPH assay), ABTS [2,2′-azino-di-(3-ethylbenzthiazoline sulfonic acid)], ferric reducing antioxidant power (FRAP), and cupric ion reducing antioxidant capacity (CUPRAC). The highest antioxidant activity by the CUPRAC method was observed in the 70% ethanolic extract of L-SD21 M – 326.49 millimoles Trolox equivalents/g dw. The major aroma constituents found in the 70% ethanolic extracts of L-UNTR21 Z were linalyl acetate and linalool at 38.64 and 7.89%, respectively. τ-muurolol, an oxidated sesquiterpene, was also found in high amounts in the 70% ethanolic extracts from lavender by-products.
