RESUMEN
Abstract Introduction: Vector-borne diseases are prevalent in the Amazon and Coastal regions of Ecuador. However, there is a scarcity of mosquito ecology studies in these areas. The most recent list of species reported for the country comprises 8 tribes, 22 genera, and 200 species. Objectives: To document the Culicidae species found in La Isla Amazon Park, Napo, Ecuador, including those with epidemiological significance; and to analyze their composition, abundance, and diversity, focusing on larval habitats during the dry and rainy periods. Methods: We evaluated different larval habitats, considering collection duration as the primary criterion. We used CDC and Shannon traps to collect adult mosquitoes during both rainy and dry periods. To assess sampling effort, we used accumulation curves and non-parametric estimators of species richness, while we employed Hill numbers to determine diversity. Additionally, we used the Berger-Parker and Pielou indices to evaluate species dominance and evenness. We conducted cluster analysis and ANOSIM tests to assess the similarity between habitats and the differences in taxonomic composition between periods. Results: We collected a total of 802 individuals from 15 species and 4 taxonomic units, 5 genera, and 4 tribes. Notably, this may be the first records of Wyeomyia felicia Dyar & Núñez Tovar and Culex derivator Dyar & Knab from Ecuador. Additionally, the presence of Culex dunni Dyar and Psorophora ferox von Humboldt (both recognized as vectors) was correlated with increased rainfall. Conclusions: The abundance of mosquitoes, including potential vector species, increased during the rainy season, indicating a higher risk of pathogen transmission. However, the relationship between rainfall amount and diversity patterns is not well-defined.
Resumen Introducción: Las enfermedades vectoriales son prevalentes en las regiones amazónica y costera de Ecuador. Sin embargo, hay una escasez de estudios de ecología de mosquitos en estas áreas. En el país se ha reportado 8 tribus, 22 géneros y 200 especies. Objetivos: Documentar las especies de Culicidae encontradas en el Parque Amazónico La Isla, Napo, Ecuador, incluyendo aquellas con importancia epidemiológica; y analizar su composición, abundancia y diversidad, enfocándose en los hábitats de las larvas durante los períodos seco y lluvioso. Métodos: Evaluamos diferentes hábitats larvarios, con la duración de la recolecta como criterio. Las trampas CDC y Shannon recolectaron mosquitos adultos durante los períodos seco y lluvioso. Evaluamos la riqueza de especies con curvas de acumulación y estimadores no paramétricos, mientras que determinamos la diversidad con los números de Hill. Además, utilizamos los índices de Berger-Parker y Pielou para evaluar la dominancia y la uniformidad de las especies. Realizamos análisis de conglomerados y la prueba ANOSIM para evaluar la similitud entre hábitats y estaciones, así como las diferencias en la composición taxonómica, respectivamente. Resultados: Recolectamos un total de 802 individuos de 15 especies y 4 unidades taxonómicas, 5 géneros y 4 tribus. Este podría ser el primer registro de Wyeomyia felicia Dyar & Núñez Tovar y Culex derivator Dyar & Knab en Ecuador. Además, la presencia de Culex dunni Dyar y Psorophora ferox von Humboldt (ambos potenciales vectores) se correlacionó con el aumento de las precipitaciones. Conclusiones: El aumento de la abundancia de mosquitos durante el periodo lluvioso indica un mayor riesgo de transmisión de patógenos. Sin embargo, la relación entre la cantidad de precipitaciones y los patrones de diversidad no está bien definida.

We present a list of bats collected above 2000 meters in Río Abiseo National Park. Sixteen bat species belonging to the Phyllostomidae and Vespertilionidae families were collected during four expeditions between 1987 and 1990. Twelve species were found within expected altitudinal ranges, but four exceeded their previously reported maximum altitudinal ranges. A comparison with other bat lists from other localities at similar altitudes is presented.

RESUMEN
El pueblo mapuche es uno de los grupos originarios de mayor importancia y nivel de conocimiento público en los países del Cono Sur de América del Sur, tanto en Chile como en Argentina, con crecientes conflictos con propietarios privados y algunos niveles estatales. Nos proponemos abordar las movilizaciones y repercusiones públicas de este pueblo a partir del accionar de sus movimientos y comunidades asentados en la zona del Parque Nacional Nahuel Huapi y áreas aledañas, en la región cordillerana de las provincias de Neuquén y Río Negro, en la Patagonia argentina. Daremos cuenta del recorrido en este periodo de 1992 hasta el presente, en el cual el pueblo mapuche se va transformando en un sujeto social y político. Analizaremos estos aspectos a la luz de las diversas transformaciones socioeconómicas y los efectos de la aplicación de las diferentes políticas públicas y legislaciones.
The Mapuche people are one of the most important and publicly known indigenous groups in the Southern Cone countries of South America, both in Chile and Argentina, and they have increasingly taken part in conflicts with private landowners and some levels of government. This article addresses the mobilizations and public repercussions of the actions of the Mapuche people, looking into their movements and communities set in the Nahuel Huapi National Park and surrounding areas, in the mountainous region of the provinces of Neuquén and Río Negro, in Argentine Patagonia. We will account for the period between 1992 and the present, during which the Mapuche people become a social and political subject. We will analyze these aspects in the light of the various socioeconomic transformations and the effects of the application of different public policies and legislations.
RESUMEN
Ashwagandha - Withania somnifera (L.) Dunal is a perennial shrub belonging to the family Solanaceae. Ashwagandha has been used for over 3000 years in traditional Indian Ayurveda for treatment of various neurological, and stress disorders. The root of Ashwagandha (ASH) is regarded as a tonic, aphrodisiac, narcotic, diuretic, anthelmintic, astringent, thermogenic and stimulant. Ashwagandha with other herbal decoctions was recognized to treat Kampavatha (Parkinson’s Disease) since 18th century. With this wide array of ethnopharmacological relevance, Ashwagandha has been recognized as one of the prominent complementary and alternative medicine to treat many neurodegenerative diseases like Alzheimer’s (AD) and Parkinson’s disease (PD). There is a prominent increase in the cases of AD and PD all over the world and it demands the requirement of complementary and alternative herbal remedies with no/minimal side effects. Many genetic factors are responsible for the onset and progression of PD. Loss-of-function mutations in the parkin gene are a major cause of early onset of autosomal recessive juvenile parkinsonism (AR-JP). Drosophila park25 loss of function mutants exhibit significantly increased number of mitochondria-endoplasmic reticulum contacts and a significantly decreased number of dopaminergic neurons in the adult brain which is the main cause of PD condition. Several studies have demonstrated the ability of Ashwagandha in imparting neuroprotection, improved locomotory ability, memory and learning abilities. The challenge lies in scrutinizing the mechanism and the pathways involved in the neuroprotective properties of this well-known herb. Here in our study, we test the possible neuroprotective effect of Ashwagandha on park25 mutants of Drosophila using lifespan analysis and climbing disability as a disease marker. Parkinson’s mimicking flies were administered with aqueous extraction of Ashwagandha-root mixed with the fly food and subjected to negative geotaxis assay. We observed that there is a prominent increase in the climbing ability in park25 treated flies compared to its age-matched untreated flies. This is the first report showing that, aqueous extraction of Ashwagandha-root extract was able to ameliorate the disease phenotype in the park25 Drosophila Parkinson’s disease model.
RESUMEN
Objective To study and estimate the public dose constraint and the atmospheric radiation capacity of an isotope industrial park, and to provide a basis for management of radioactive effluent discharge in isotope industrial parks. Methods We collected the natural environment data, meteorological data, and population distribution and dietary data as well as the source terms of radioactive airborne effluents of an isotope industrial park. The public dose constraint value of the isotope industrial park was determined based on the natural environmental radiation hazard level. The atmospheric environmental radiation capacity of the industrial park was estimated by the all-pathways method. Results The public dose constraint value of the industrial park was 0.2 mSv/a. At the end of industrial park planning, the maximum individual effective dose to the public caused by airborne effluent discharge was 1.07×10−6 Sv/a, which accounted for 0.54% of the public dose constraint value. The proportions of discharges of airborne radionuclides to respective environmental radiation capacities ranged from 0.04% to 4.34%. Conclusion The determined public dose constraint value of the isotope industrial park can be used as the total radiation capacity of the regional atmospheric environment to constrain the discharge of radioactive effluents. The environmental radiation capacity of each radionuclide can be estimated by the all-pathways method considering the comprehensive impact of radionuclide discharges, which is suitable for the control and management of isotope production enterprises in industrial parks.
RESUMEN
ABSTRACT Background: Despite their worldwide occurrence, the distribution and role of insect-specific flaviviruses (ISFs) remain unclear. Methods: We evaluated the presence of ISFs in mosquitoes collected in São Paulo, Brazil, using reverse transcription and semi-nested polymerase chain reaction (PCR). Some of the positive samples were subjected to nanopore sequencing. Results: Twelve mosquito pools (2.8%) tested positive for flavivirus infection. Nanopore sequencing was successfully performed on six samples. Phylogenetic analysis grouped these sequences into genotype 2 of Culex flavivirus (CxFV). Conclusions: The identification of CxFV genotype 2 at new locations in São Paulo highlights the importance of understanding the role of ISFs in mosquito vector competence.
RESUMEN
Objective:To explore the importance of managing retro-orbicularis oculi fat (ROOF) in double-fold eyelid operation for patients with swollen upper-eyelid.Methods:From January 2018 to December 2020, 76 cases of swollen upper-eyelid were treated with double-fold eyelid operation by PARK method. In operation, an oval shape ROOF was removed from the outside-to the inside, and then appropriate lateral intraorbital fat was also removed. If fleshy orbicularis oculi muscle and anterior tarsus fat affected appearance of double-fold eyelid, both of them might be removed properly.Results:All patients were followed up from seven days to two years, two cases presented with shallowed double-fold eyelid, 5 cases of lacrimal gland prolapse had good lacrimal gland reduction and no recurrence; 4 cases of ptosis had normal corneal exposure and natural appearance after correction; the swollen upper-eyelid was obviously improved in 74 cases, and restoration stage was short, the apperaence and radian of doule-fold eyelid were beautiful, local scar was slight, satisfactory operative effect was achieved.Conclusions:In double-fold eyelid operation by PARK method for patients with swollen upper-eyelid, an ideal effect would be achieved, if transconjunctival route and fleshy orbicularis oculi muscle are appropriately removed in turn according to the reasons to give rise to swollen upper-eyelid.
RESUMEN
Microhabitat factors associated with the habitat of barking deer (Muntiacus vaginalis) were examined and compared between summer and winter seasons. Habitat characteristics and preferred habitat were measured by locating direct and indirect signs. To quantify the habitat utilization of barking deer, each selected study site was sampled for floral diversity from 2015 to 2017. Quadrats were deployed along transect lines to determine seasonal distribution. Barking deer were not evenly distributed across vegetation types in the study area; they occurred more often in the broad-leaved forest than in Chir pine forest, at an elevational range of 550-850 m, in thick vegetation on steep slopes. The most preferred habitat included trees and shrubs with 30% and 69% cover, respectively. Barking deer avoided thicker tree cover, possibly as it hinders movement and escape from predators. No significant difference (χ2 = 6.37, df = 3, p = 0.19) in seasonal vegetation cover was recorded.
Fatores de micro-hábitat associados ao hábitat do veado (Muntiacus vaginalis) foram examinados e comparados entre as estações de verão e inverno. As características do hábitat e o hábitat preferido foram medidos, localizando sinais diretos e indiretos. Para quantificar a utilização do hábitat de cervos-latidos, cada local de estudo selecionado foi amostrado para a diversidade floral de 2015 a 2017. Quadrats foram implantados ao longo de linhas de transecto para determinar a distribuição sazonal., Veados-latidos não foram distribuídos uniformemente pelos tipos de vegetação na área de estudo; ocorreram com mais frequência na floresta de folhas largas do que na floresta de pinheiros Chir, em uma faixa de elevação de 550-850 m, em vegetação densa, em encostas íngremes. O hábitat mais preferido incluía árvores e arbustos com 30% e 69% de cobertura, respectivamente. O veado-latido evitou uma cobertura de árvores mais espessa, possivelmente porque impede o movimento e a fuga de predadores. Nenhuma diferença significativa (χ2 = 6,37; df = 3; p = 0,19) na cobertura vegetal sazonal foi registrada.

Wood-boring beetles develop in live trees and dead wood, performing ecological services such as decomposition and regulation of forest resources. Species of the Cerambycidae family, widely distributed in the world, bore into the trunks of trees and dead wood in native and cultivated areas. The objective is to report the first host plant for Thoracibidion lineatocolle (Thomson, 1865) (Coleoptera: Cerambycidae) and a new host plant for Temnopis megacephala (Germar, 1824) (Coleoptera: Cerambycidae) in the Brazilian Atlantic Forest biome. Three logs, with one-meter-long by 20 cm in diameter, were cut from the trunk of a healthy Anadenanthera colubrina (Fabaceae) tree in October 2013 and tied in the understory at 1.5m high in the Rio Doce State Park, Minas Gerais State, Brazil. The logs, exposed in the forest, were each removed after 40, 80 and 120 days and stored individually in a cardboard box in the "Laboratório de Campo do Projeto de Ecologia de Longa Duração (PELD-CNPq)" in the Rio Doce State Park. A total of 94 individuals of T. lineatocolle and 228 of T. megacephala emerged from the A. colubrina logs. This is the first report of a host plant for T. lineatocolle and a new host plant for T. megacephala.

Objective:To investigate the modified application of orbicularis oculi muscle-levator aponeurosis composite tissue flap fixation technique (modified Park method) in double-eyelid surgery.Methods:From June 2019 to March 2021, 823 patients included 92 males and 731 females, aged from 18 to 45 years with mean (31.4±7.9) years, in which 142 patients with slightly ptosis were selected to receive the treatment in the Department of Plastic Surgery of the Affiliated Hospital of Nangjing University of TCM. The symmetry of bilateral double eyelids after operation was evaluated by the third party. The marginal reflex distance (MRD1) was measured before and 6 months after operation, and the difference between preoperative and postoperative MRD1 (ΔMRD1) was calculated. And the postoperative complications were counted. The patients were followed up from 6 to 12 months after surgery to evaluate the long-term results.Results:The patients were followed up for 4-22 months (mean 10 months) after operation. And the incisions of all the 823 cases had primary healling. Most patients had smooth upper eyelid crease, upturned lashes and dynamic fold. The skin tended to spread evenly without dimple. The symmetry evaluation by the third party showed that there were 764 patients with symmetry and basic symmetry after operation, the symmetry rate was 92.8%; 59 patients with asymmetry, the asymmetry rate was 7.2%. The data of MRD1 increased significantly 6 months after operation, from (3.25±0.72) mm to (3.64±0.61) mm, and the ΔMRD1 was (0.38±0.76) mm ( t=-20.41, P<0.05). The difference between the two groups was statistically significant. The double eyelid line became shallow in 8 cases and disappeared completely in 3 cases. The double eyelid curve of the patients was natural and smooth after the operation. And there was no obvious sunken scar and pretarsal fullness. Conclusions:The " modified Park technique" blepharoplasty can obtain a more firm, symmetrical and natural appearance. And the mild ptosis could be corrected by this method. The anatomical structure can be identified clearly, and the surgical results are highly repeatable. It is worth promoting.
RESUMEN
Abstract We describe a new species of the genus Podanotum Torres & Johnson, 1996, Podanotum pajaten Farfán, Cerdeña & Bálint sp. nov. from northern Peru, associated with the Andean treeline ecotone adjacent to cloud forest and wet grassland at 3200 m above sea level. Description of this new species is based on one female adult and is distinguishable from its congeners by the combination of the following morphological characters: dorsal wing pale blue, forewing discoidal line present on ventral side, hindwing tailed, and ostium bursae distally toothed. Podanotum pajaten sp. nov. is separated geographically from the closest spatial species, P. glorissimum Bálint & Wojtusiak, 2002, by approximately 100 km to the south, and represents the second species described for Peru. An identification key to all known species of Podanotum is provided, stating their distributions by country.

La descripción de esta nueva especie está basada en una hembra adulta que se distingue de sus congéneres por la combinación de los siguientes caracteres morfológicos: vista dorsal de las alas de color azul pálido, línea postdiscal del ala anterior presente en vista ventral, cola corta en ala posterior, y parte distal del ostium bursae dentada. Podanotum pajaten sp. nov. está separada geográficamente de la especie espacialmente más cercana, P. glorissimum Bálint & Wojtusiak, 2002, por aproximadamente 100 km hacia el sur, y representa la segunda especie descrita de Perú. Una clave de identificación es presentada para todas las especies conocidas de Podanotum, con indicación de los países de ocurrencia.
RESUMEN
Abstract The large number of less-known coastal drainages in the Atlantic Forest still represents an important gap in the knowledge of ichthyofauna. It is evaluated the taxonomic diversity, frequency and constancy of occurrence, and the distribution of species in the various segments of the Perequê-Açu river basin, state of Rio de Janeiro, Brazil. Twelve sampling campaigns resulted in 13,423 individuals, belonging to seven orders, 10 families, 21 genera, and 23 native species. Cyprinodontiformes and Siluriformes represented about 87.2% of the total abundance, mainly due to the contribution of Phalloceros anisophallos and Schizolecis guntheri, which account for 63.2% of the total sampled individuals. The analysis of constancy of occurrence reveals that 78.3% of the drainage species are residents, with approximately 93% of the residents of the Carrasquinho River sub-basin. The Sertões River sub-basin had the largest number of species in total: 18. The rarefaction curve did not reach an asymptote, although Chao 2 and bootstrap estimate the richness of 23.9 species and 23.7 species, respectively. The results of PERMANOVA, PCoA, and SIMPER indicate that the fish composition along the catchment is not homogeneous. The conservation status of species is also discussed, regionally, nationally, and globally.
Resumo O grande número de drenagens costeiras pouco estudadas na Mata Atlântica ainda representa uma lacuna importante no conhecimento da ictiofauna. Avalia-se aqui a diversidade taxonômica, frequência e constância de ocorrência e a distribuição das espécies nos vários segmentos da bacia do rio Perequê-Açu, estado do Rio de Janeiro, Brasil. Doze campanhas de amostragem resultaram em 13.423 indivíduos, pertencentes a sete ordens, 10 famílias, 21 gêneros e 23 espécies nativas. Cyprinodontiformes e Siluriformes representaram cerca de 87,2% da abundância total, devido sobretudo à contribuição de Phalloceros anisophallos e Schizolecis guntheri, que respondem por 63,2% do total de indivíduos amostrados. A análise de constância de ocorrência revela que 78,3% das espécies da drenagem são residentes, sendo cerca de 93% dos residentes da sub-bacia do rio Carrasquinho. A sub-bacia do rio Sertões apresentou o maior número de espécies no total: 18. A curva de rarefação não atingiu uma assíntota, embora Chao 2 e bootstrap estimem a riqueza de 23,9 espécies e 23,7 espécies, respectivamente. Os resultados de PERMANOVA, PCoA e SIMPER indicam que a composição dos peixes ao longo da bacia hidrográfica não é homogênea. Discute-se, ainda, o status de conservação das espécies, regional, nacional e globalmente.
RESUMEN
The Ministry of the Environment’s the Onsen Stay policy calls for the creation of a plan to increase the demand for long-term stays in spa health resorts. A report on the development of such plans, focusing on spa health resorts, has been published. According to the report, it was suggested that five external environments around the spa resort should be utilized in combination with each other, namely: making the most of the natural environment, making the most of the historical and cultural environment, making the most of the artificial environment and facilities, making the most of different environments by moving around, and making the most of the nighttime hours. In this report, I will try to verify whether these five types of programs are appropriate or not by using the program for a stay in the national park resort village. In addition, I will evaluate whether the proposed program will enhance the demand for a stay in the national park resort village, and suggest improvements. The 11 national park resort villages in this report are Retreat Azumino Hotel, Norikura Kogen, Minami-Izu, Fuji, Noto-Senrihama, Echizen-Mikuni, Omihachiman, Minami-Awaji, Takeno Kaigan, Nanki-Katsuura, and Hiruzen Kogen. I confirmed the validity of the five types, and the necessity to create a program for a stay in these villages by making the best use of the five external environments of the spa. In addition, it was shown that the importance of the program was not so much the diversity of the external environment of the spa along the walking course, but rather the nearness to the place of origin and destination and the sustainability of the program as well as the time to complete it.

RESUMEN
Parkin, also known as PARK2, has been closely related to Parkinson's disease (PD) since its discovery. It is considered to be a neuroprotective gene. With the in-depth understanding for its structure, Parkin has been unveiled as an E3 ubiquitin ligase. Parkin is involved in the regulation of cell cycle, mitochondrial homeostasis, energy metabolism and other cellular processes, and is closely related to many diseases. It even plays completely opposite roles in the same pathway, namely cell proliferation and apoptosis, indicating that this must be a gene with an extremely broad and important role. This article summarizes the discovery and structure of Parkin and its self-inhibiting characteristics, focusing on the ubiquitination process that it participates in as E3 ubiquitin ligase and the resulting autophagy, protein degradation, changes in protein subcellular localization and protein interaction. These may all serve as the basis for Parkin to prevent PD and suppress tumors. On this basis, two reasons for Parkin abnormalities leading to PD are summarized: abnormal protein quality control and mitochondrial dysfunction, and extended to cardiovascular and kidney diseases caused by the abnormality of Parkin due to mitochondrial dysfunction. The internal connection between Parkin and cancer is also introduced from the aspects of Parkin as a tumor suppressor, regulating cell cycle, apoptosis and metastasis, oxidative stress and energy metabolism. By maintaining the active state of Parkin or enhancing its expression, it may be possible to improve the condition of PD patients. But the mechanism of Parkin's inhibition of tumor growth remains to be deciphered, and the potential role of Parkin in mediating the relationship between PD and cancer risk should be strengthened. These follow-up in-depth studies and their role in the diagnosis and treatment of related diseases and application of target molecules laid the foundation.
RESUMEN
Objective To understand the influence of a pharmaceutical industrial park in North China on the gross α / β radioactivity levels in the surrounding environment. Methods Environmental samples in the surrounding area of the Pharmaceutical Industry Park in 2019, including aerosols, sedimentation ash, well water and biological samples, etc., were collected and treated according to standard methods. FYFS～400X low background α and β radioactivity detector was used to detect the gross α/β radioactivity level. Results In 2019, the gross α/β radioactivity levels in aerosols in a single month were 795～978 µBq/m3 and 1111～1304 µBq/m3, respectively, and in the sedimentation ash were 29～34 Bq/m2 and 36～49 Bq/m2, respectively. They were 0.120～0.235 Bq/L and 0.126～0.343 Bq/L in well water, 0.077～0.149 Bq/kg and 100.2～219.4 Bq/kg in the vegetable, 0.171～0.581 Bq/kg and 154～296 Bq /kg in the chicken, 0.147～0.376 Bq/kg and 97～190 Bq/kg in pork, respectively. Conclusion The monthly gross α/β radioactivity levels in the surrounding environment of the pharmaceutical industrial park has seasonal variation in aerosol and sedimentation ash, but no significant change in well water and biological samples, which requires continuous dynamic monitoring
