Authors: Zhai Xiaohui , Kang Yulin , Yuan Xiuxia , Wang Yaping , Lu Sifen , Lu Zuhong
Published: February 2022

Purpose: To investigate the probable effect of oxidative stress on cognitive deficits in schizophrenia.

Methods: A total of 149 first-episode schizophrenia (FES) patients and 65 healthy controls were enrolled in this study. Psychiatric symptoms were evaluated using Positive and Negative Syndrome Scale, while cognitive function was assessed using MATRICS Consensus Cognitive Battery. Oxidative parameters, including glutathione (GSH), thioredoxin (TRX), nitric oxide (NO), homocysteine (Hcy) and superoxide dismutase (SOD)]; hypersensitive C-reactive protein (Hs-CRP, an inflammation marker); lipopolysaccharide (LPS) and CD4+T cell sub-sets (Th1, Th2, Th17 and Treg cells) were measured in all subjects, while PANSS was evaluated in FES patients only.

Results: Levels of the oxidants, NO, Hcy and inflammatory parameters (Hs-CRP, LPS, Th1, Th2 and Th17) were higher in FES patients than in controls (p < 0.05). In contrast, levels of antioxidants (GSH and SOD) in FES patents were lower than those in controls (p < 0.05). Moreover, TRX was higher in schizophrenia patients than in controls (p < 0.05). The changes in levels of these biomarker indicated oxidative stress responses. There were statistically significant differences in hemogram and T cell subtype between FES and control (p < 0.05). Results from fMRI analysis revealed schizophrenia- induced lesions in the encephalic region associated with cognition function.

Conclusion: Oxidative stress (OS) induces immune response which eventually leads to impairment of cognition.

Authors: Wang Yan , Wang Mengchun , Li Yan
Published: February 2022

Purpose: To study the effects of a combination of mosapride and fluoxetine in patients with functional dyspepsia-associated anxiety, and its impact on gastrointestinal function.

Methods: One hundred (100) cases of patients with anxiety linked to functional dyspepsia, who were admitted to the Department of Gastroenterology of Shengjing Hospital, China Medical University from January 2019 to May 2020, were retrospectively selected and randomly divided into control and study groups (n = 50). The control group patients received moxapride monotherapy, while those in the study group were given moxapride in combination with fluoxetine. The two groups of patients were compared daily for 4 days with respect to treatment effectiveness, Mental Status Scale in Non-psychiatric Settings (MSSNS), Barthel Index (BI), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), time intervals for flatulence and defecation, as well as bowel sounds, and levels of gastric juice and cholecystokinin.

Results: Treatment effectiveness, BI index, number of intestinal rumblings, and level of gastrin in the study group were significantly higher than those in control group after 1, 2, 3 and 4 days of treatment (p < 0.05). Moreover, scores for SAS, SDS and MSSNS, as well as time intervals for flatulence and defecation, and level cholecystokinin in the study group were significantly lower than those in control group (p < 0.05).

Conclusion: The combination of mosapride and fluoxetine has high application benefit for patients with anxiety associated with functional dyspepsia when compared with the control.

Authors: Zhou Guang , Li Zheng , Sun Lei , Wang Hongjuan , Li Qinghua
Published: February 2022

Purpose: To evaluate the factors influencing deep vein thrombosis (DVT) in stroke patients, and the effect of anticoagulant intervention.

Methods: A total of 208 stroke patients in Jiaozhou Central Hospital of Qingdao from March 2018 to March 2020 were assigned to DVT group (n = 84) and non-DVT group (n = 124). Their clinical data were analyzed to identify risk factors. Thereafter, the DVT group were randomized to control group and study group (n = 42 each). Conventional treatment and low molecular heparin plus treatment were given to the groups, respectively. Activities of daily living (ADL) and treatment outcomes were compared.

Results: Univariate analysis showed that age, smoking history, Wells score, duration of bed rest, limb immobilization time after interventional therapy, D-dimer and TGs differed between the two groups (p < 0.05). Multivariate logistic regression analysis revealed that age ≥ 60 years old, smoking history, Wells score ≥ 2 points, duration of bed-rest ≥ 7 days, limb immobilization time ≥ 1 day after intervention, D- dimer < 0.95 mg/L and TG < 1.84 mmol/L were risk factors for DVT. After treatment, ADL and total treatment effectiveness in the study group were higher than in the control group (p < 0.05).

Conclusion: Age ≥ 60 years, smoking history, Wells score ≥ 2 points, duration of bedrest ≥ 7 days, limb immobilization time ≥ 1 day after intervention, D-dimer < 0.95 mg/L and TG < 1.84 mmol/L are risk factors for DVT. The anticoagulant used (rivaroxaban) seems to improve daily living and reduce clinical symptoms.
MiR-558 inhibits odontogenic differentiation of human periodontal ligament fibroblasts by negatively regulating Jagged-1/Notch signaling pathway
Authors: Song Shengzhang , Yan Zhuanjun , Wu Wangxi
Published: February 2022

Purpose: To investigate the potential effect and explore the underlying mechanism of action of miR-558 in the odontogenic differentiation of human periodontal ligament fibroblasts (hPLFs).

Methods: Human periodontal ligament fibroblasts were treated with osteogenic induction medium to induce odontogenic differentiation. The efficiency of odontogenic differentiation was determined using Alizarin red staining and alkaline phosphatase (ALP) activity assays. The expression levels of osteogenic markers, including Osterix and Runx2, were determined by Western blotting, while mRNA levels of Jagged-1, HES1 and HEY1 were assessed by quantitative real-time polymerase chain reaction (qRT-PCR).

Results: MiR-558 was down-regulated during the odontogenic differentiation of hPLFs. Alizarin red staining and ALP activity data indicate that miR-558 significantly inhibited the odontogenic differentiation of hPLFs. Osterix and Runx2 expression levels were significantly decreased in the miR-558 mimic group but significantly increased in miR-558 inhibitor group compared with those in NC group (p < 0.01). Moreover, miR-558 regulated Notch signaling by targeting Jagged-1, while Jagged-1 knockdown suppressed the odontogenic differentiation of hPLFs.

Conclusion: MiR-558 inhibits the odontogenic differentiation of human periodontal ligament fibroblasts by negatively regulating Jagged-1/Notch signaling pathway, and thus, could serve as a potential target to regulate the odontogenic differentiation of hPLFs.

Authors: Hartmann Leonardo Da Silva , Rodrigues Rodrigo Schütz
Published: February 2022

Este trabalho descreve e ilustra o desenvolvimento e a morfologia de plântulas de Ormosia smithii Rudd, revisando a relevância sistemática dos atributos de plântulas na classificação infragenérica de Ormosia nos neotrópicos. Sementes de O. smithii foram coletadas de populações em áreas de mata ciliar no estado de Roraima, Brasil. A espécie tem plântulas cripto-hipógeas-armazenadoras, eofilos estipulados e 1-foliolados nos três primeiros nós. Como atualmente delimitadas, seções e séries neotropicais de Ormosia apresentam variação nos tipos de plântulas e filotaxia dos primeiros eofilos. Com algumas possíveis exceções, plântulas não forneceram caracteres para estas categorias infragenéricas em Ormosia. Embora os caracteres de plântulas sejam relativamente uniformes em O. sect. Ormosia ser. Coccinea, foi possível distinguir O. smithii das demais espécies pertencentes à série que ocorrem na Amazônia, com base no comprimento do epicótilo

Authors: Silveira Maura Imazio da , Kern Dirse Clara , Berredo José Francisco , Costa Jucilene Amorim , Costa Marcondes Lima da
Published: February 2022

A região amazônica foi ocupada por grande diversidade de povos e culturas, em uma longa e dinâmica trajetória de desenvolvimento. Foi marcada pela adaptação à disponibilidade dos recursos naturais, bem como manejo do ambiente, a exemplo das terras pretas arqueológicas (TPA). Esses solos apresentam coloração escura, elevados teores de P, Ca, Mg, Zn e Mn, associados a artefatos cerâmicos, líticos, restos de fauna e flora. A pesquisa foi realizada nos sítios Bitoca 1 e Bitoca 2, localizados na área da Floresta Nacional Tapirapé-Aquiri (FLONATA), município de Marabá, Pará. Esses sítios são constituídos por pequenas manchas de TPA, que foram correlacionadas a áreas de habitação (cabanas e arredores). Essas áreas foram ocupadas por período aproximado de um milênio e podem ou não ter sido habitadas simultaneamente. Observações realizadas durante as escavações, aliadas às diferentes datações e às variações nos teores de P, Ca, Mg, Zn e Mn, tanto dentro como entre manchas, sugerem áreas com ocupações sucessivas e/ou reocupação, com atividades diferenciadas relacionadas ao tipo e à intensidade de materiais orgânicos (animal ou vegetal) e inorgânicos (fragmentos de cerâmica) descartados e/ou tempo de utilização do espaço.

Published: February 2022

Neste estudo, foi verificada a influência do estresse hídrico sobre a decomposição da serapilheira. As coletas foram realizadas na Floresta Nacional de Caxiuanã (PA), em uma área experimental onde a floresta amazônica foi coberta com plataformas de plástico, que impediram que a água da chuva chegasse ao solo, e em uma área controle em condições naturais, adjacente à área experimental. Foram fixadas no solo 180 bolsas de decomposição de folhas em cada uma das áreas, com três diferentes tipos de malha de náilon (com 0,2, 2,0 e 1,0 mm), que foram coletadas com intervalos de 60, 120, 210 e 300 dias. Observou-se que a decomposição menor ocorreu na floresta privada de água da chuva. A variação nos três diferentes tipos de malhas foi significativa na quantidade de material remanescente. Para o período de permanência de 60 e 120 dias, a perda de massa de folhas foi de aproximadamente 50% do material remanescente e, para o período de 300 dias, o material remanescente foi mais significativo, com redução que variou de 68,9, 70,1 e 54,4%, para malhas grossa, média e fina, respectivamente. Não foram encontradas diferenças significativas entre os dois experimentos após 12 meses de decomposição nas duas áreas estudadas.

Florestas tropicais são reguladoras do clima e o padrão de variabilidade dos elementos meteorológicos representa fisicamente interdependência entre os fluxos térmicos e hídricos para a floresta e a atmosfera. A presente investigação analisa uma série de dados (precipitação, temperatura do ar, umidade relativa do ar, radiação solar global, velocidade e direção do vento) na Floresta Nacional de Caxiuanã, Pará. O estudo ocorreu entre 2005 e 2013, usando-se uma classificação sazonal, definida da seguinte forma: dezembro a junho, como chuvoso, e julho a novembro, como menos chuvoso. Dois métodos estatísticos básicos foram aplicados para testar as diferenças sazonais e avaliar a “sincronicidade” entre as variações sazonais dos elementos meteorológicos: a) teste não-paramétrico (Mann-Whitney; p <0,05) para a análise horária; b) Teste de estatística circular (método Watson-Williams). Concluímos que em termos horários a direção do vento e a temperatura do ar mudaram entre períodos úmidos e secos, mas a intensidade do vento não mostrou alterações significativas. Também houve mudanças significativas na radiação global, precipitação e umidade relativa. A variabilidade da velocidade do vento foi sincronizada com variabilidade na direção do vento, precipitação e temperatura do ar, mas não com a umidade relativa e radiação solar total. Esses resultados geram uma descrição básica dos mecanismos físicos que controlam a dinâmica do tempo sazonal nas florestas tropicais.

Published: February 2022

A depressão do Pantanal está sujeita à inundação anual, alagando a maior parte da planície e criando enorme heterogeneidade de unidades da paisagem ou de geoambientes. O Pantanal do Abobral é uma sub-região que compõe o Pantanal. O estudo teve como objetivo caracterizar as unidades ambientais do Pantanal do Abobral, utilizando-se de atributos físico-químicos dos solos. A paisagem foi estratificada pelas condições de hidromorfismo, fitofisionomia, relevo e solos. No Geoambiente Cordilheira, área não alagável, verificou-se ocorrência de conchas de caramujos enterradas no solo, o que influenciou na presença de Chernossolos. Esse Geoambiente apresentou os maiores estoques de C-org e de teores de fósforo disponíveis. A ocorrência de horizontes petrocálcicos nas Cordilheiras contribui para a deciduidade da vegetação e para a estabilidade daquelas frente aos processos erosivos. Nos ambientes sazonalmente alagados, Lagoa Intermitente, Campo com Cambará e Corixo, ocorrem Planossolos de maneira generalizada, o que contribui para a manutenção de níveis temporários mais elevados do lençol freático, devido ao horizonte B plânico com caráter vértico.

A floresta amazônica apresenta elevadas temperaturas e grandes quantidades de precipitações anuais, embora ocorram grandes variações interanuais desses elementos meteorológicos. A temperatura do ar (Tar) e a umidade relativa do ar (UR) dentro e acima de uma floresta são resultado de complexas trocas energéticas através dos processos de reflexão, transmissão e absorção da energia solar. Esse estudo foi realizado na Floresta Nacional de Caxiuanã, Pará, Brasil, e teve como objetivo principal avaliar a variabilidade sazonal da temperatura e umidade do ar a partir de uma análise de perfil vertical no interior da floresta, com medidas alturas de 2 m, 16 m, 28 m e 42 m, com registros a cada 30 minutos, durante o período de 2012 a 2016. Os resultados indicaram grande sazonalidade nestes elementos meteorológicos, e as maiores temperaturas ocorreram no nível do dossel (28 m), e as menores foram observadas próximo à superfície (2 m), devido a atenuação da radiação solar no interior da floresta. Os maiores valores da UR foram observados próximo à superfície (2 m), e os menores ocorreram acima do dossel, devido as maiores velocidades do vento neste nível. Estes resultados indicam grande variabilidade espaço-temporal destes elementos meteorológicos, o que influencia no comportamento dos organismos vivos que habitam aquele ambiente florestal.

Published: February 2022

Esse é o primeiro estudo sobre a ocorrência de fungos filamentosos cultiváveis em associação com o trato digestório (TD) de larvas de Phylloicus (Trichoptera: Calamoceratidae). Larvas de Phylloicus (n=137) foram coletadas em igarapés de baixa ordem da Amazônia brasileira (estados de Roraima, Pará e Tocantins) e dissecadas para se obter o conteúdo do TD. Fungos filamentosos foram cultivados a partir de cada TD. Eles apresentaram diferentes morfologias (média geométrica ± desvio padrão de morfoespécies por TD = 6,2 ± 6,4), bem como variação significativa no tamanho das populações (unidades formadoras de colônias por TD = 8,5 ± 47,0 x 101), tanto entre paisagens ecológicas como entre larvas de uma mesma localidade. O fato de larvas de Phylloicus comumente abrigarem fungos filamentosos em seu TD (94,9%), como verificado neste estudo, indica que, potencialmente, esses microrganismos exercem papéis importantes na interface de interação com seus hospedeiros, que podem estar relacionados com a degradação de substratos lignocelulósicos. A partir dessa perspectiva, o TD de Phylloicus sp. poderia representar uma fonte de fungos com potencial biotecnológico.
Resistividade no entorno do aterro sanitário municipal de Boa Vista, Roraima, Brasil: implicações ambientais
Authors: Souza Lena Simone Barata , De Andrade Guilherme Gonzaga
Published: February 2022

As curvas de resistividade elétrica (ρa) definidas para o aterro sanitário de Boa Vista configuraram dois grupos geoelétricos: (1) não contaminado e (2) contaminado. O grupo 1 (N, NE, E, SE, S, SW e W, ao entorno do aterro) definiu quatro zonas de resistividade representativas do litotipo arenoso (30.000 < ρa < 10.000 Ω.m), areno-argiloso (10.000 <ρa < 5.000 Ω.m), argilo-arenoso (5.000 < ρa < 1.000 Ω.m) e argiloso (1.000 < ρa < 700 Ω.m). O grupo 2, subdividido em 2A, 2B e 2C, apontou que as anomalias condutivas de 2A (36 < ρa < 250 Ω.m) são a pluma de contaminação do aterro, já as zonas condutivas de 2B (250 < ρa < 500 Ω.m) estão relacionadas à migração da pluma, indicando concentração dela para NW, N e NE. Os contaminantes tendem a migrar a NE da área, em direção ao igarapé Auaí Grande, sendo, ainda, limitados pelo subgrupo 2C.

Published: February 2022

As implicações ocasionadas pelas mudanças no uso e na cobertura da terra têm afetado o comportamento de bacias hidrográficas. Neste contexto, o estudo teve como objetivo analisar a relação entre a vazão e as métricas de paisagem, para os anos de 2004, 2008, 2010 e 2014, na bacia do rio Capim, localizada no nordeste do estado do Pará. Para isso, utilizou-se métricas de paisagem, a fim de relacioná-las com a vazão do rio. Com base na relação entre as análises das métricas de paisagem e o escoamento, foi possível identificar que os índices de total de bordas (TE) e de agregação (AI) são os que melhor se associam às mudanças no regime de vazão da bacia hidrográfica. Desse modo, pode-se verificar que a fragmentação das classes floresta e pastagem possui papel fundamental na alteração hídrica da bacia. Portanto, as alterações nessas classes ao longo da bacia associam-se ao desenvolvimento da pecuária, a qual impulsiona a economia dos municípios da região, todavia, tem favorecido o desmatamento e a fragmentação florestal, comprometendo o cenário hídrico local. Os índices de mensuração da paisagem mostraram-se uma metodologia vantajosa para o entendimento da dinamicidade de usos e de interferências antrópicas atuantes na bacia hidrográfica.
Bosque como refúgio para as briófitas: o caso do parque Ibirapuera, em São Paulo, Brasil
Authors: Visnadi Sandra Regina
Published: February 2022

A brioflora está empobrecendo em muitos países e, no entanto, forma um grupo de plantas importante para a sustentabilidade da sociedade. O presente artigo trata das briófitas do parque Ibirapuera – que possui áreas com bosque heterogêneo, entre áreas onde predominam edificações, córrego e lagos –, na cidade de São Paulo. O material totaliza 688 exsicatas depositadas no Herbário Maria Eneyda Pacheco Kauffmann Fidalgo, do Instituto de Botânica, além de duplicatas, no Herbário da Prefeitura do Município de São Paulo. O parque Ibirapuera possui 63 espécies de briófitas. Muitas delas se restringem a determinadas áreas do parque, onde várias ocorrem ainda em locais únicos. A maior riqueza da brioflora nas áreas com bosque heterogêneo, em relação às áreas onde predominam as edificações, comprova que as primeiras áreas servem como refúgio para várias espécies de briófitas, no parque Ibirapuera. Esses resultados demonstram a importância que a arborização tem para a conservação da brioflora do parque, a qual – agora conhecida – pode contribuir para o monitoramento da qualidade ambiental do local. A flora de briófitas destaca-se por apresentar uma variedade e uma espécie endêmicas do Brasil, duas espécies ameaçadas de extinção, sendo uma delas citada pela primeira vez para o país.

Authors: Gonçales-Silva Raísa , De Almeida Odair José Garcia , De Souza Luiz Antonio
Published: February 2022

Folhas de seis espécies de Leandra e Miconia foram investigadas estruturalmente, com atenção aos caracteres de interesse para separação das espécies e dos gêneros, bem como àqueles que podem estar relacionados ao estresse hídrico. Os espécimes foram coletados no Parque Estadual do Guartelá, Brasil, e descritos morfologicamente. Estudos anatômicos foram realizados em amostras foliares embebidas em historesina e seccionadas em micrótomo rotativo. A microscopia eletrônica de varredura foi feita em material fixado em glutaraldeído. As folhas de Leandra têm forma lanceolada-ovada, enquanto as folhas de Miconia possuem as lâminas oblongo-lanceoladas e lanceoladas. Ambos os gêneros possuem a vascularização do pecíolo composta de feixes colaterais, bicolaterais e anficrivais. As folhas são hipoestomáticas e dorsiventrais, variando no número de estratos dos parênquimas. A nervura central consiste em feixes concêntricos colaterais (em forma de U, em V ou circulares) ou concêntricos. A morfologia do indumento, a estrutura do mesofilo e a vascularização da nervura central são características de interesse para o diagnóstico de espécies. Provavelmente, são espécies que evitam a seca e consistem em plantas capazes de reduzir ou compensar a perda de água.
Jueces penales y punitivismo en España
Authors: Blay Gil Ester , Varona Gómez Daniel , López-Riba José María , Jiménez García Juan Ramon
Published: February 2022

Este trabajo busca conocer el papel de los jueces en la deriva punitiva que según la doctrina mayoritaria caracteriza la evolución reciente del sistema penal español. Ello no es posible acudiendo a datos oficiales, por lo que recurrimos a investigaciones realizadas con datos primarios sobre imposición y ejecución de penas. Se comparan dos conjuntos de datos generales existentes correspondientes a 1998 y 2015/16 respectivamente. Para aislar la variable “juez”, se comparan únicamente los delitos contra la propiedad sin violencia ni intimidación, cuya penalidad no ha sufrido reformas legislativas relevantes. Los análisis permiten verificar que en 2015/16 se impuso en mayor medida la pena de prisión, aunque de menor duración que en 1998, y suspendida con mayor frecuencia.
El trabajo concluye que, de acuerdo con los datos disponibles, los jueces españoles no parecen haber contribuido a la deriva punitiva experimentada por nuestro sistema penal

Authors: Yakubovskaya A.G. , Tupitsyna I.A. , Dubovik A.M.
Published: February 2022

Technological principles of manufacturing a lead tungstate crystal from archaeological lead for use in low-background experiments to search for rare events are presented. The influence of the conditions for obtaining single crystals of archPbWO4 on the photochromic effect in single crystals is investigated. By minimizing deviations from the stoichiometric composition, it was possible to improve the optical parameters of the lead tungstate single crystal. Single crystals with improved optical parameters have been obtained using double crystallization and the introduction of an excess of archPbO, which makes it possible to consistently influence various defects in crystals of archPbWO4.

Published: February 2022

Rural development is not new concept in India. Whereas eighty percent of the population resides in rural area and seventy-two percent of the work force depends upon agriculture & allied activities. Agriculture obviously plays a very important role in rural development. Therefore, Indian Economy is dependents on Agro-based activities. Rural development is being given top priority in our national planning. Hence, eradication of rural priority is the key of National Economy. Our rural problems are linked with basic needs of the people such as livelihood, literacy; resources are primary reasons of poverty in our country. It is creating gainful self-employment, which is the biggest challenge for the development organization as well as the society by making sustainable use of the natural resources & human skill.

Rural development involves raising the socio-economic status of the rural population on a sustainable basis through optimum utilization of local resources, both natural and human. While external help is necessary, rural development can achieved only when the rural people actively participated in the development process, in this research work has tried to focus on comparative study of rural development.

Published: February 2022

The Percoll density gradient centrifugation (PDGC) method is frequently used in the sexing of spermatozoa. However, this method causes damage to the spermatozoa membranes, resulting in a decreased quality of spermatozoa. We analysed the impacts of phospholipid PC (phosphatidylcholine) and EGTA (ethylene glycol bis (β-aminoethyl ether) N,N,N',N'-tetraacetic acid) Ca2+ free buffer on the quality of bovine spermatozoa after the PDGC process, using semen from Friesian Holstein (FH) bulls aged 5 - 8 years. The following variables were observed: spermatozoa motility, spermatozoa viability, spermatozoa membrane integrity, spermatozoa that have not experienced capacitation, spermatozoa that have experienced capacitation and spermatozoa that have undergone acrosomal reaction. The results showed that the administration of phospholipid PC + EGTA Ca2+ free buffer to spermatozoa, followed by the PDGC process, could maintain or further improve the values of all variables. In the PDGC process, phospholipid PC 10% + EGTA Ca2+ free buffer at 1 mM was most suitable.

It was proposed clearly in China's 14th Five-Year Plan to promote comprehensively rural revitalization. China will implement fully the strategy of rural revitalization, improve continuously the core competitiveness of agricultural products, speed up the implementation of rural construction, and take the road of socialist rural areas with Chinese characteristics. As an important part of the implementation of China's rural revitalization strategy, many of the relevant systems play a very obvious role in promoting the development of rural revitalization. Meanwhile, in the process of rural development in recent years, the demand for the protection of intellectual property rights related to agricultural development is also increasing. For this reason, it is essential to combine intellectual property rights with rural revitalization more effectively and accelerate the realization of high-quality rural development.

Insights from Early Mathematical Models of 2019-nCoV Acute Respiratory Disease (COVID-19) Dynamics
Authors:   University of the Philippines Los Banos, Rabajante Jomar
Published: February 2022

In December 2019, a novel coronavirus (SARS-CoV-2) has been identified to cause acute respiratory disease in humans. An outbreak of this disease has been reported in mainland China with the city of Wuhan as the recognized epicenter. The disease has also been exported to other countries, including the Philippines, but the level of spread is still under control (as of 08 February 2020). To describe and predict the dynamics of the disease, several preliminary mathematical models are formulated by various international study groups. Here, the insights that can be drawn from these models are discussed, especially as inputs for designing strategies to control the epidemics. Proposed model-based strategies on how to prevent the spread of the disease in local setting, such as during social gatherings, are also presented. The model shows that the exposure time is a significant factor in spreading the disease. As crowd density increases, the higher the chance an infected person could infect other people. The attendees of the social gathering should have effective protection or preventive measures (e.g., administrative and engineering controls) to minimize further disease transmission.

The crown fuel characteristics of the most dominant coniferous species in Korea, Pinus densiflora, were investigated in Gyeongbuk province, Korea. Allometric equations using DBH as independent variable were also developed for the estimation of crown fuel load (needles, branches: <0.5 cm, 0.5-1 cm, 1-2 cm, and 2-4 cm in diameter), crown volume, and aboveground biomass. The average crown bulk density in Youngju and Bonghwa was 0.47 kg m-3, while in Daegu, it was 0.29 kg m-3. The crown bulk density of needles and branches with a diameter of <1 cm was 0.21 kg m-3in Youngju, 0.27 kg m-3 in Bonghwa, and 0.13 kg m-3 in Daegu. The average crown base height was 5.10 m in Youngju, 5.20 m in Daegu, and 3.60 m in Bonghwa. Overall, the Pinus densiflora stand in Bonghwa is more hazardous if crown fire occurs compared to the other study sites based on different crown fuel characteristics. The allometric models developed were able to explain at least 79% of the observed variation in the biomass and crown volume. For the aboveground biomass, Daegu had the highest mean tree biomass with 103.54 kg, followed by Youngju (67.35 kg) and then Bonghwa (37.72 kg).

Andrographolide (AG) is known to possess some pharmacological properties such as anti-inflammatory, antioxidant, anti-dengue, anti-tumor and anti-tuberculosis. Green extraction techniques such as ultrasound and microwave have shown the effectiveness in extracting high purity AG from Andrographis paniculata or Sinta. Ultrasound-assisted extraction (UAE), which operates at non-thermal conditions, prevents the thermal degradation of AG while microwave-assisted extraction (MAE) allows an increased extraction yield. This study aimed to determine the effect of sequential ultrasound- microwave-assisted extraction (UMAE) in the yield of AG and its bioactivity assessment. The UAE obtained its highest AG yield of 539.24 mg L-1 at 10 minutes sonication time and MAE with 781.65 mg L-1 at 5 minutes irradiation time with 420 W microwave power. The UMAE obtained the highest AG yield of 1,066.49 mg L-1 when sequentially exposed to 10 minutes sonication and 10 min irradiation with a microwave power of 280 W. Cytotoxic activity testing of Sinta extract containing AG from UMAE confirmed a lethal concentration (LC50) with value at 76.02 mg L-1. Furthermore, it has an intermediate susceptibility to Escherichia coli but resistant to both Bacillus clausii and Klebsiella spp., highlighting the potential of its valuable medicinal applications.

Published: February 2022

Coastline is the connection line between the land and the sea, and its extraction and analysis are of great significance to the coastal zone resources and environmental protection. Using remote sensing and Geographic Information Sysytem (GIS), coastline change from 1995 to 2015 in the Fujian Province, China, was extracted. The temporal and spatial evolution characteristics of coastline length, type and spatial location in the Fujian Province, China were analyzed. The coastline length continued to increase from 1995.29 km to 3555.036 km. The overall change intensity in 2010-2015 was the highest, reaching 0.87%, followed by 1995-2000. The smallest change occurred in 2005-2010. Based on the intensity changes in the six coastal cities of Fujian Province, Zhangzhou City showed the strongest coastline change. Except for the stability in 2000-2005, the changes that occurred during other years were larger. Fuzhou is the city with the smallest coastline changes, which have remained balanced for 25 years. Overall, the length of the rocky coastline and the sandy coastline generally show a downward trend, while the artificial coastline and the muddy coastline generally show an upward trend.
Fragmentation Trajectories as a Review of Existing and Proposed Single-valued Fragmentation Indices
Authors:   School of Environmental Science and Management, Vergara Dante Gideon , Lasco Rodel , Walker Robert , Alcantara Antonio , Ancog Rico , Sanchez Patricia Ann , Tiburan Cristino
Published: February 2022

Two related single-valued landscape fragmentation indices D and F are proposed, based on patch aggregation, shape complexity, and percent of the focal pixels on the landscape, and are computed using Fragstats metrics on a colonization landscape continuously fragmented over 36 years. The same was done for two existing single-valued fragmentation indices, i.e., the Matheron index based solely on normalized unlike joins, and the Normalized Hypsometric Curve (NHMC) index from GUIDOS Toolbox. All were plotted chronologically, and also against percent non-forest (%nf) of the landscape, and the trajectories were compared for behavior. The NHMC index starts high even if deforestation is low, and continues increasing even further as deforestation continues, while the other three indices all start close to zero and increase gradually. F mimics D very closely, and the Matheron index only behaves differently from F and D at the end of the data range. The deviation may be due to patch aggregation, which the Matheron index does not consider. An accepted single-valued fragmentation index computed from Fragstats landscape metrices could allow for cross-study comparisons relating fragmentation with any other attribute on or of the landscape, hopefully advancing the science of fragmentation in landscape ecology as cross-study generalizations would now be possible.
Biodegradation of Carcinogenic Reactive Azo Dyes by Indigenous Bacterial Consortium X5RC5
Authors:   JECRC University, Rahi Ravi Kant , Gupta Varsha
Published: February 2022

Reactive azo dyes are considered as a major source of water and soil contamination. Carcinogenicity and the recalcitrant nature of these dyes is a worldwide problem. Exclusion of these dyes from the effluent is necessary for a clean and green environment. A bacterial consortium X5RC5 was developed for the effective removal of two of the primary reactive azo dyes utilized widely in textile industries (reactive orange 3R and reactive red HE7B). The consortium includes two indigenous bacterial isolates, Lysinibacillus macroides and Stenotrophomonas acidaminiphila, from textile effluent. The X5RC5 completely degraded the reactive orange 3R in 4 days and reactive red HE7B in 5 days of incubation periods. In two days, more than 50% degradation was observed for both dyes. Biodegradation of these dyes was affirmed through the UV-Vis spectra and Fourier-transform infrared spectroscopy (FTIR) analysis. This investigation advances the utilization of consortium X5RC5 as a biological tool for the bio-handling of effluent containing dyes.

Published: February 2022

Customary inheritance law does not recognize the principle of "legitieme portie" or the absolute part of Islamic inheritance law where inheritance rights have been determined for certain portions of inheritance as stipulated in the Qur'an Surah An-Nisa. The problem of this research is how the harmonization of values and principles in customary inheritance law and Islamic inheritance law in Semende, South Sumatra Province as a contribution to the formation of national inheritance law? The results showed that the harmonization of values and principles in customary inheritance law and Islamic inheritance law in Semende, South Sumatra Province as a contribution to the formation of national inheritance law is that adat can be used as Islamic law, that is, custom in this relationship is a habit in the daily life involved in terms of muamalah (community), not about 'worship.' Because, regarding worship people should not add or subtract what has been determined by Allah as written in the Koran and which has been arranged by the Sunnah of His Apostles as contained in the book Valid Hadiths.
