Disease surveillance remains a challenge in the Philippines due to its limited resources. 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.
由于菲律宾资源有限,疾病监测仍然是一项挑战。在国家狂犬病控制规划中整合基于基因组学的监测可以进一步了解狂犬病病毒(RABV)的进化和传播动态,因此可以为公共卫生决策提供信息。该试点研究使用了先前报道的达沃市和邻近省份的49个RABV序列,以评估靶向测序作为全基因组测序的廉价替代方法的效用。我们采用不同的树距离指标来比较RABV全基因组(WG)和RABV单个基因。利用IQTree2和BEAST构建系统发育树,比较系统发育信号、树的拓扑结构和进化模式的差异。3个主要支系的系统发育信号没有显著差异,在基因和位点水平上对抽样方差和潜在方差有很强的支持价值。对WG基因与单个基因的贝叶斯系统发育树进行比较,结果表明二者在替代率和分化时间上无显著差异。此外,所有个体基因树的亲缘距离(pd)均与同一菌株的RABV WG呈正相关且一致,相关值均在99%以上,排除了仅使用单个基因就错过进化动力学相关发现的可能性。基于我们详细的遗传分析结果,RNA依赖的RNA聚合酶(L)和磷酸化蛋白(P)片段被确定为研究达沃市当地流行RABV变异进化分析的最佳生物标志物,因为它们的树相对于WG的pd接近。诸如基于基因的监测等成本较低的选择将使地方政府能够追踪和监测病毒的实际遗传多样性和传播,这可能导致设计和实施重点战略。

According to the World Health Organization (WHO), the elderly and people with comorbidities are most vulnerable to COVID-19 infection. 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.
根据世界卫生组织(世卫组织)的数据,老年人和有合并症的人最容易感染COVID-19。因此,弱势群体面临的挑战和威胁需要有针对性的干预措施。虽然公共卫生监测方法最近取得了进展,以满足用户的信息需求,但传染病数据的数量和复杂性都有所增加,导致越来越难以促进与公众进行风险沟通,决策者也越来越难以采取知情措施保护公众健康。此外,专门针对达沃地区弱势人群的COVID-19时空疾病监测战略的实施此前从未探索过。本文利用地理空间工具调查了2020年3月3日(最早记录的发病日期)至2021年8月31日期间达沃地区的COVID-19发病率。这些变量通过地形图和刻度符号可视化,随后通过空间自相关和热点分析进行检验。据观察,整个地区的热点都在高密度地区。由于病例高度集中,这些地区存在更大的感染风险。然而,在偏远的城市发现了高病死率,在这些城市,获得COVID-19医疗设施是一个难题。在COVID-19环境和未来类似COVID-19的疾病爆发中,本研究的结果可能为政府办公室和其他相关机构提供见解,以改善医疗保健系统和计划,例如提供和启动适合社区弱势群体的量身定制的隔离和咨询机制。

Momentum Distribution in the Classically Forbidden Region of a Ballistic Particle at the Turning Point 弹道粒子在拐点处经典禁区内的动量分布

A wave packet 𝚿𝚿(𝒙𝒙, 𝒕𝒕) of a single particle has a statistical correlation between its position x and momentum p, quantified as the position-momentum covariance. 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.
单个粒子的波包𝚿𝚿(𝒙𝒙,)在其位置x和动量p之间具有统计相关性,量化为位置-动量协方差。协方差影响波包的传播和通过某一点的概率电流。本文给出了协方差的另一个效应:非零协方差可以表现为区域动量密度的不对称性。考虑一个选择性测量|𝚿𝚿⟩→|𝚿𝚿[𝒙𝒙𝟏𝟏,𝒙𝒙𝟐𝟐]⟩在初始状态|𝚿𝚿⟩投射到状态|𝚿𝚿[𝒙𝒙𝟏𝟏,𝒙𝒙𝟐𝟐]⟩较小的区域内𝒙𝒙𝟏𝟏<𝒙𝒙<𝒙𝒙𝟐𝟐。预计的动量表示状态是𝚽𝚽[𝒙𝒙𝟏𝟏,𝒙𝒙𝟐𝟐]=⟨𝒑𝒑|𝚿𝚿[𝒙𝒙𝟏𝟏,𝒙𝒙𝟐𝟐]⟩和相应的动量密度|𝚽𝚽[𝒙𝒙𝟏𝟏,𝒙𝒙𝟐𝟐]|𝟐𝟐地区动量密度。本文研究了均匀重力作用下分子大小的粒子(用高斯波包𝚼𝚼表示)在经典拐点处的运动。本文考虑了𝚼𝚼的协方差对经典禁区区域动量密度的影响。具有给定协方差的初始状态𝚼𝚼皮肤病被投射到经典禁止区域,产生状态𝚼𝚼𝑪𝑪𝑪𝑪。如果相应的动力波函数是𝚽𝚽𝑪𝑪𝑪𝑪,区域动量密度是𝚷𝚷𝑪𝑪𝑪𝑪= |𝚽𝚽𝑪𝑪𝑪𝑪|𝟐𝟐。我推导了𝚷𝚷𝑪𝑪𝑪𝑪的解析表达式,它表明非零协方差预测了经典禁区中的不对称动量密度。这为我们提供了一种控制措施,可以使用适当的协方差在经典禁止区域中准备优选的动量分布,但代价是由于不确定性原理(随着粒子的构型空间减小)而产生更大的动量不确定性。另外,由于动量密度是由动量测量统计实验得到的,所以我们可以通过与预测动量分布的比较来测量协方差,也可以间接检验等效原理。

This study aimed to investigate the effects of home-based dynamic jumping exercise (DJE) in middle-aged with prehypertension. Sedentary individuals were recruited from Banphai district, Khon Kaen, Thailand. Thirty (30) eligible subjects were randomly allocated to the control (CG) and exercise (EX) groups. The CG was instructed about lifestyle modification, and the EX was asked to act like the CG but additionally elongated with DJE program for 8 wk (50 min/day, 3 d/wk at moderate intensity). The primary outcomes were systolic (SBP) and diastolic blood pressure (DBP). 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). In conclusion, the DJE program in combination with lifestyle modification was considered a non-pharmacological intervention for controlling blood pressure and improving physical performance in middle-aged adults with prehypertension.
本研究旨在探讨家庭动态跳跃运动(DJE)对中年高血压前期患者的影响。研究人员从泰国孔敬的班帕区招募了久坐不动的人。30名符合条件的受试者随机分为对照组(CG)和运动组(EX)。指导CG改变生活方式,并要求EX像CG一样行动,但额外延长DJE计划8周(50分钟/天,3天/周,中等强度)。主要结局是收缩压(SBP)和舒张压(DBP)。有4个次要结果,包括颈-股脉波速度(cfPWV)、5次坐立测试(FTSST)、计时起身测试(TUGT)和生活质量(QOL)。8周后,除TUGT (p = 0.07)和QOL外,所有结果的EX均较基线显著改善(p < 0.001)。另一方面,与基线相比,CG组环境域的生活质量显著降低(p < 0.05)。然而,除cfPWV外,两组间收缩压、舒张压、FTSST和TUGT均有显著差异(p = 0.06)。综上所述,DJE计划结合生活方式改变被认为是一种非药物干预措施,可用于控制高血压前期中年人的血压和改善身体机能。

The experiment was designed to test the suitability of sugarcane extract (SE) as a local extender for the cryopreservation of the Banaba native chicken semen by comparing the effects of different cryoprotective agent concentrations [i.e. glycerol and dimethyl sulfoxide (DMSO)] and thawing temperatures on the post-thaw semen quality. Twelve (12) 29-month-old Banaba native roosters served as semen donors. Only samples that passed the preliminary semen quality assessment of > 70% motility and morphology were further processed and analyzed using a computer- assisted semen analyzer (CASA). Pooled ejaculate samples were cryopreserved with SE extender containing 3, 5, 7, or 9% (T3%, T5%, T7%, and T9%) glycerol or DMSO concentration levels. The results showed that the inclusion level of cryoprotectants and thawing temperatures have no significant effect on the percent motile sperm, percent progressive sperm, percent normal morphology, and percent viability. The type of cryoprotectant used in cryopreservation of the semen had a significant effect on all the semen quality parameters.

Antimicrobial resistance (AMR) is a threatening global health challenge with an estimated annual death toll of 10 million by 2050 if unabated. 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.
抗菌素耐药性(AMR)是一项威胁全球健康的挑战,如果不减少,到2050年估计每年死亡人数将达到1000万。因此,迫切需要寻找新的临床候选药物来源,以开发有效对抗耐药感染和癌症的药物。温泉和火山环境是新型天然产物(NPs)的宝贵来源,包括聚酮、生物碱和肽,但大部分尚未开发和研究不足。来自这些生态位的微生物已经被发现在极端温度和恶劣条件下发展出独特的防御能力,从而导致具有独特化学结构和显著生物活性的新分子的生物合成。本文综述了2006-2022年从温泉和火山微生物中提取的生物活性NPs,重点介绍了它们的化学结构和生物潜力。值得注意的是,与目前的化疗药物相比,这些化合物对几种癌细胞的细胞毒作用更强,这表明药物开发的潜力很大。对极端微生物的持续探索无疑会带来许多生物活性分子的发现,这些分子对生物技术或制药应用具有潜在的价值。

The objectives of the present study were focused on the comparative study of lavender (Lavandula angustifolia Mill.) raw material and its essential oil industry by-products. 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. Therefore, lavender and its industrially generated by-products could represent a promising source of biologically active and aroma compounds with potent high antioxidant activity.
本研究主要对薰衣草原料及其精油工业副产物进行了比较研究。研究了该副产物作为具有生物活性的极性和非极性化合物的天然来源在食品、化妆品和制药工业中的应用潜力。研究了工业蒸汽蒸馏副产物(L-SD20 M、L-SD21 M和L-SD21 Z)和未经处理的薰衣草(L-UNTR21 Z)的4种薰衣草样品,测定了它们的化学成分和抗氧化能力。L-SD20 m 70%乙醇提取物中检测到9种酚酸(没食子酸、原儿茶酸、绿原酸、咖啡酸、丁香酸、对香豆酸、阿魏酸、水杨酸和迷迭香酸)和5种黄酮类化合物[(+)-儿茶素、(-)-表儿茶素、芦丁、橙皮苷和槲皮素],L-SD21 Z 70%乙醇提取物中酚类化合物含量最高,为16.08±0.38 mg没食子酸当量/ g干重(dw)。L-SD21 M 70%乙醇提取物黄酮含量最高,为3.89±0.44 mg槲皮素当量/ g dw。采用DPPH法、ABTS[2,2 ' -氮基-二-(3-乙基苯并噻唑啉磺酸)]清除自由基能力、铁还原抗氧化能力(FRAP)和铜离子还原抗氧化能力(CUPRAC)四种方法评价提取物的抗氧化能力。用CUPRAC法测定,L-SD21 M - 326.49毫摩尔Trolox当量/g dw的70%乙醇提取物的抗氧化活性最高。L-UNTR21 Z 70%乙醇提取物的主要香气成分为乙酸芳樟醇和芳樟醇,分别为38.64%和7.89%。在薰衣草副产品70%乙醇提取物中也发现了大量的氧化倍半萜τ-穆罗尔。因此,薰衣草及其工业副产品可能是一种具有高抗氧化活性的生物活性和芳香化合物的有前途的来源。

Knowledge of behavior and perception changes about the use of household disinfectants in the Philippines during the COVID-19 pandemic is largely unexplored. Through a survey, we took into consideration the locals’ responses from Sorsogon, Philippines. Alcohol and oxidizing agents were found to be the most commonly used household disinfectant products in Sorsogon. Most of the respondents have shifted to the everyday use of disinfectant products during the pandemic. Increased disinfectant consumerism was positively associated with genders, employed respondents, and students but not among housewives and non-employed respondents. Most of the respondents agreed that various factors are needed to consider when choosing disinfectants. They were also knowledgeable about the possible effects of disinfectant wastes on the environment. How would these collective positive behavior changes during the new normal era warrant further attention.
在2019冠状病毒病大流行期间,菲律宾人对使用家用消毒剂的行为和认知变化的了解在很大程度上尚未得到探索。通过一项调查,我们考虑了菲律宾索索贡当地人的反应。酒精和氧化剂是索索贡地区最常用的家用消毒剂。大多数答复者在大流行期间已转向日常使用消毒产品。消毒液消费主义的增加与性别、就业受访者和学生呈正相关,但与家庭主妇和非就业受访者无关。大多数受访者认为,在选择消毒剂时需要考虑各种因素。他们还了解消毒废物对环境可能产生的影响。在新常态时代,这些集体的积极行为变化如何值得进一步关注?
