The butterflies of Cristalino Lodge, in the Brazilian southern Amazonia: An updated species list with a significant contribution from citizen science / As borboletas do Cristalino Lodge, no sul da Amazônia: Uma lista atualizada de espécies com contribuição significativa da ciência cidadã

Abstract The richest butterfly communities in the world are found in the Amazon rainforest. Despite of this, and the importance of species inventories for the knowledge of diversity patterns, there are few comprehensive lists of butterflies for localities in the Brazilian Amazon. Here, we present an updated list of the butterflies of Cristalino Lodge (Alta Floresta, Mato Grosso, Brazil), in southern Amazonia, based on specimens collected by researchers and photographic records taken by ecotourists, butterfly watchers, and tour guides. With 1010 species recorded, this is currently the largest list of butterflies published for a single locality in Brazil and the first to reach (and surpass) 1000 species, with more than one third of the records coming from citizen science. The region has about 29% of the butterfly species in Brazil and one of the greatest richnesses known in the country, inferior only to areas in the western Amazon. Its fauna is mainly composed of species widely distributed in lowland Amazonia, with the addition of some species typical of the Cerrado. It has a relatively low number of species of the tribe Ithomiini (Nymphalidae: Danainae), generally considered a good indicator of the total butterfly diversity in neotropical forests, which points to the need for caution when using a single taxonomic group as a surrogate of richness of entire communities. The present work highlights the importance of citizen science and ecotourism centers for inventories and data on species distribution in diverse tropical forests.

Resumo As comunidades de borboletas mais ricas do mundo são encontradas na Amazônia. Apesar disso, e da importância dos inventários de espécies para o conhecimento dos padrões de diversidade, existem poucas listas abrangentes de borboletas para localidades da Amazônia brasileira. Aqui, apresentamos uma lista atualizada das borboletas do Cristalino Lodge (Alta Floresta, Mato Grosso, Brasil), no sul da Amazônia, baseada em espécimes coletados por pesquisadores e em registros fotográficos feitos por ecoturistas, observadores de borboletas e guias turísticos. Com 1010 espécies registradas, essa é atualmente a maior lista de borboletas publicada para uma localidade no Brasil e a primeira a atingir 1000 espécies, sendo mais de um terço dos registros provenientes da ciência cidadã. A região apresenta cerca de 29% das espécies de borboletas do Brasil e uma das maiores riquezas conhecidas no país, inferior apenas a áreas no oeste da Amazônia. Sua fauna é composta principalmente por espécies amplamente distribuídas na planície amazônica, com adição de algumas típicas do Cerrado. Possui um número relativamente baixo de espécies da tribo Ithomiini (Nymphalidae: Danainae), que é geralmente considerada uma boa indicadora da riqueza total de borboletas em florestas neotropicais, o que aponta para a necessidade de cautela ao se usar um grupo taxonômico como previsor da riqueza de comunidades inteiras. O presente trabalho destaca a importância da ciência cidadã e dos centros de ecoturismo para inventários e dados sobre distribuição de espécies em florestas tropicais diversas.

A Review on Pharmacological Properties of Christia vespertilionis

@#Commonly referred to as ‘daun rerama’, Christia vespertilionis has increased in popularity in traditional and modern medicine. This review aims to report the relevance of this plant in terms of its traditional uses, pharmacological actions, phytoconstituents, extractions methods, and identify the research gaps and future potentials. The review is conducted as per PRISMA guidelines; a database search was conducted in Web of Science, Science Direct, Scopus and Google Scholar from 1996 to 2021. Results show that to date, phytochemicals such as alkaloids, flavonoids, quinones, and others have been identified, corresponding to its range of pharmacological activities that include anti-cancer, anti-malaria, and antioxidant. There have also been claims of antidiabetic activity but not supported by enough scientific evidence. Study on molecular and gene expression was still lacking. There is a good future in the research of this plant with many potential aspects to be investigated.

Multimodal imaging features of butterfly-like pattern retinal pigment epithelial dystrophy / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To explore the multimodal imaging features of butterfly-like retinal pigment epithelial dystrophy(BPD)patients.<p>METHODS: Retrospective analysis of the multimodal imaging of 18 BPD patients(36 eyes)from January 2016 to July 2019, including fundus color photography, infrared photography, autofluorescence, fundus fluorescein angiography, indocyanine green angiography, optical coherence tomography(OCT), and optical coherence tomography angiography(OCTA). <p>RESULTS: A typical fundus color photography showed the appearance of a butterfly-like lesion caused by abnormal pigmentation. The appearance of the butterfly was not obvious after the lesion progressed, and the corresponding region shrinks; Infrared photography showed the yellow lesions clearly in the BPD patients, which are white highlight images; Autofluorescence showed patchy, spotted butterfly wing performance. When the lesion progressed, autofluorescence did not show typical butterfly changes, but it showed the damage of pigment epithelial cells; Fundus fluorescein angiography and choroidal angiography, in addition to showed butterfly lesions, can more accurately display vascular lesions, especially choroidal neovascularization(CNV); OCT showed lesions located between the retinal pigment epithelial(RPE)layer and the photoreceptors. As the lesion progressed, the pigment epithelium showed enlarged lesions correspondingly. Secondary CNV patients can be seen to break RPE; OCTA showed that the lesions were not obvious at the deep and superficial layers of the retina. But the choroidal blood flow signals were lost in some degrees in OCTA, and the blood flow images of CNV can be detected sensitively.<p>CONCLUTION: Multimode imaging technology can provide imaging features of progression in BPD patients, which helps clinicians to understand the disease more deeply.

Biological aspects of Caligo teucer (Lepidoptera: Nymphalidae) with banana tree leaves

ABSTRACT Caligo teucer (Linnaeus, 1758) is widely distributed in Argentina, Bolivia, Brazil and Ecuador. The objective was to study biological aspects of Caligo teucer japetus Stichel, 1903 with banana leaves, Musa sapientium L. (Zingiberales: Musaceae), in the butterfly garden, under environmental conditions, and in the laboratory of biological control of insects at the Universidade Federal de Viçosa in Viçosa, Minas Gerais state, Brazil at 24 ± 2 oC, 68 ± 10% relative humidity and 12 hours photophase. The duration of the egg incubation, larvae, pupa and egg to adult periods of C. teucer japetus were, respectively, 11.8 ± 0.1; 53.9 ± 0.9; 17.9 ± 0.3 and 82.6 ± 1.0 days for females, and 11.8 ± 0.1; 50.3 ± 0.6; 18.4 ± 0.3 and 79.4 ± 0.6 days for males in cages in the laboratory. The longevity of C. teucer japetus adults was 26.0 ± 10.4 and 47.5 ± 8.7 for females and 24.7 ± 3.5 and 35.4 ± 15.7 for males in the butterfly garden and in laboratory cages, respectively. The high survival and the relatively short period of development of its immature stages confirm that banana leaves are an adequate food substrate for the development and survival of Caligo teucer japetus.

Butterfly Cartilage Tympanoplasty Long-term Results: Excellent Treatment Method in Small and Medium Sized Perforations

OBJECTIVES: The aim of this study was to evaluate and report the long-term results of the butterfly cartilage tympanoplasty. Short-term and long-term hearing outcomes were compared according to age and perforation location as well. METHODS: Ninety-three patients who were diagnosed with noncomplicated chronic otitis media and underwent microscopic transcanal butterfly cartilage tympanoplasty due to anterior, posterior, and central tympanic membrane perforation were included. Age, gender, follow-up time, pre- and postoperative pure tone audiometry thresholds (both air and bone conduction), pre- and postoperative air-bone gaps (ABGs), if any residual perforation was noted. RESULTS: At the end of the follow-up period, successful closure occurred in 88 of 93 patients and success rate is 94.6%. In all patients, including those with residual perforations, the mean preoperative bone conduction threshold was 15.9 dB (range, 5 to 50 dB) among all groups whereas mean air conduction threshold was 36.4±15.1 dB (range, 10 to 90 dB) preoperatively and 28.8±14.3 dB in 6th month follow-up and 24.9±14.1 dB 24th month follow-up. Preoperative mean ABG was 22.1±7.1 dB (range, 5 to 40 dB) whereas 13.3±5.9 dB 6 months after surgery and 11.9±5.5 dB 24 months after surgery. There was a significant difference between pre- and postoperative ABG in both 6th and 24th month follow-up (P(6 mo-24 mo) < 0.05). Furthermore, preoperative mean air conduction differed significantly from postoperative 6th and 24th month follow-up mean air conduction thresholds (P < 0.05). CONCLUSION: We suggested that butterfly cartilage tympanoplasty can be safely performed in small, moderate, and even large perforations, as the hearing outcomes and successful closure rate are similar to those of other surgical methods. Moreover, it can be performed under local anaesthesia and it has low complication rates.

Clinics in diagnostic imaging (175). Corpus callosum glioblastoma multiforme (GBM): butterfly glioma

A 54-year-old man presented with change in behaviour, nocturnal enuresis, abnormal limb movement and headache of one week's duration. The diagnosis of butterfly glioma (glioblastoma multiforme) was made based on imaging characteristics and was further confirmed by biopsy findings. As the corpus callosum is usually resistant to infiltration by tumours, a mass that involves and crosses the corpus callosum is suggestive of an aggressive neoplasm. Other neoplastic and non-neoplastic conditions that may involve the corpus callosum and mimic a butterfly glioma, as well as associated imaging features, are discussed.

An Observational Study on Butterfly Underlay Cartilage Tympanoplasty.

Background: The paring of tympanic membrane is usually done by doing myringoplasty with temporal is fascia graft. Methods: A newer technique of butterfly cartilage underlay grafting has been used in 50 patients with small to moderate size safe perforation. Results: The result of the study would be analysed for hearing improvement and graft uptake. Hearing gain of 0-5 dB was observed in 4 patients, 6-10 dB in 3 patients, 11-15 dB in 14 patients, 16-20 dB in 22 patients and 21-25 dB in 7 patients. Conclusion: Butterfly cartilage myringoplasty is a very good technique for closure of small to moderate size central perforations.

Comparative Evaluation of Presence of Butterfly Effect in Transverse Sections of Incisors, Canines and Premolars – An In-Vitro Study

Aim To compare the occurrence of the butterfly effect in the roots of incisors, canines and premolars. Materials and methodology A total of 30 extracted teeth were selected (incisors, canines and premolars of 10 each) and embedded in the clear acrylic and then sectioned into six thin sections of 1-mm thickness and are observed under light microscope at 5× magnification. Scoring was given on the presence or absence of the butterfly effect. Results 80% of the incisor and canine groups showed the presence of butterfly effect, whereas it is 70% in case of premolar group. Conclusion No significance difference in presence of butterfly effect in incisors, canines and premolars, with very slight predominance in incisors and canines. If present, this was uniform all along the root.

Taxonomic review of Gallio Evans, 1955 (Lepidoptera, Hesperiidae, Hesperiinae): one less monotypic genus of Moncini

ABSTRACT Moncini is the tribe of Hesperiidae that comprises the greatest diversity of small, brown, hard to identify skippers. The group is peculiarly classified as having many monotypic genera, thus offering low informative value to its systematics. This study presents a review of the genus Gallio Evans, 1955, a genus formerly recognized as monotypic, and describes three new species, Gallio imperatriz sp. nov. from Maranhão, Brazil, Gallio furtadoi sp. nov. from Mato Grosso, Brazil and Gallio eti sp. nov. from Madre de Díos, Peru and Acre, Brazil (type locality). A lectotype for Vehilius carasta Schaus, 1902 is designated. Gallio is therefore redescribed and illustrations and diagnosis to its species are provided.

Differentiating between Traumatic Pathology and Congenital Variant: A Case Report of Butterfly Vertebra

Butterfly vertebra is a rare congenital malformation of the spine, which is usually reported in the literature as an isolated finding. We describe a 40-year-old woman that presented to our emergency department with back pain and sciatica. Initial radiological evaluation revealed an incidental finding of a L4 butterfly vertebra in the anteroposterior and lateral view radiographs. The patient presented with no neurological deficit. This rare congenital anomaly is usually asymptomatic, and awareness of its non-traumatic nature is critical in order to establish a correct diagnosis. Further evaluation of the patient is necessary to exclude pathologic fracture, infection, or associated vertebral anomalies and syndromes, such as Alagille, Jarcho-Levin, Crouzon, and Pfeiffer syndromes. Furthermore, in the emergency setting, awareness of this entity is needed so that a correct diagnosis can be established.

Comparison of Short- and Long-term Hearing Outcomes of Successful Inlay Cartilage Tympanoplasty Between Small and Large Eardrum Perforations

OBJECTIVES: To compare the short- and long-term hearing outcomes after successful inlay cartilage tympanoplasty between patients with small ( or =50%) eardrums perforations. METHODS: This is a retrospective case series study conducted in a tertiary referral center. Twenty-five patients who underwent 27 procedures were enrolled. Their mean age was 60.26 years (range, 42 to 76 years). The mean follow-up time was 18.86 months (range, 12.30 to 35.83 months). The preoperative, initial postoperative, and long-term hearing results in patients with total repair of the eardrum were analyzed. RESULTS: In the small size group, the average (+/-standard deviation) air-bone gap (ABG) closure was 1.08+/-7.53 dB in the short-term and 2.33+/-11.56 dB in the long-term hearing examinations. There was no difference between short- and long-term ABG closure (P=0.689). In the large size group, the average ABG closure was 9.77+/-9.40 dB in the short-term and 16.25+/-6.01 dB in the long-term hearing examinations. There was a significant difference between short- and long-term ABG closure (P=0.029). CONCLUSION: Patients with large perforations have continuous hearing improvement and ABG closure for more than one year. In contrast, the short- and long-term postoperative ABGs are almost the same in patients with small perforations. More long-term postoperative follow-up of hearing results is necessary for large perforations.

Medical institutions challenged by“Broken window effect”and“Butterfly effect”in the new media era and countermeasures / 中华医院管理杂志

False and negative information has brought forth serious impacts on doctor-patient relationship in the new media era as a result of “Broken window effect”and “Butterfly effect”.The underlying reasons are herd mentality,the public’s need to vent their discontent,the subjectivity of information distribution on the Internet and lack of proper supervision and punishment mechanism.Medical Institutions should pay special attention to the new media,leveraging it to improve doctor-patient relationship by making official voice,guiding public opinion,solving problems,and providing comfortable social environment and rational public opinion environment on the Internet.

External morphology of the immature stages of Neotropical heliconians: IX. Dione glycera (C. Felder & R. Felder) (Lepidoptera, Nymphalidae, Heliconiinae)

External morphology of the immature stages of Neotropical heliconians: IX. Dione glycera (C. Felder & R. Felder) (Lepidoptera, Nymphalidae, Heliconiinae). The biology of the Andean silverspot butterfly Dione glycera (C. Felder & R. Felder, 1861) is still poorly known. This species is restricted to high elevations in the Andes, where the immature stages are found in close association with species of Passiflora belonging to the section Tacsonia (Juss.) Harms, especially P. tripartida var. mollissima (Kunth), which is grown for subsistence by villagers. Herein we describe and illustrate the external features of the egg, larva and pupa of D. glycera, based on light and scanning electron microscopy.
