Published: May 2022

Polycystic ovary syndrome (PCOS) is a common endocrine-related cause of infertility in women and has an unknown etiology. Studies have shown that rhamnocitrin (Rha) exhibits positive effects on the reproductive system. This study investigated Rha’s antifibrotic effects on PCOS rats and revealed its underlying mechanisms. Female SD rats were randomized into 4 groups (

CMC by oral gavage; the PCOS group received letrozole (1 mg/kg); the PCOS+Rha group received letrozole and Rha (5 mg/kg); the PCOS+Met group received letrozole and Met (265 mg/kg) for 21 days. At the study end, Rha treatment restored letrozole-induced alterations in the relative ovarian weights, body weight, and relative weights of uterine and visceral adipose tissues. Histological observation showed that Rha ameliorates ovarian structure and fibrosis in PCOS. Administration of Rha reduced letrozole-induced metabolic dysfunction by ameliorating the levels of TC, TG, and HDL-C in the PCOS rats. Rha treatment also modulated the serum levels of sex hormones, which decreased T, E2, and LH and increased FSH in PCOS rats. In addition, Rha treatment modulated insulin resistance and increased gene expression of antioxidant enzymes (Cat, Sod2, Gpx3, Mgst1, Prdx3, Gsta4, Gsr, and Sod1) in the ovaries of the PCOS rats. Finally, Rha treatment appeared to increase the activity of PPAR-γ and inhibit the TGF-β1/Smad pathway in the ovaries of the PCOS rats. Our findings suggest that Rha significantly ameliorated metabolic disturbances and ovarian fibrosis in the PCOS rats. Rha perhaps is an effective compound for preventing ovarian fibrosis in the future.
The Innovative Development of Russian Modern Oil Painting under the Background of Internet of Things and Artificial Intelligence
Authors: Mou Yanlin
Published: May 2022

Contemporary Russian oil paintings have realized the inheritance and development of classical paintings. Although it is deeply influenced by European and American oil painting creations, it is commendable that it did not fully follow the creative framework of Western works, but realized the image of absorbing the essence of it and then integrating it into Eastern literature and art, and finally formed the integration of Chinese and Western oil paintings in Russian oil painting with a unique creative style. With the continuous development of science and technology, mankind has put forward higher-level requirements for nature, society, science, and technology, and many new things are rising in these aspects. As an emerging industry, Internet of things technology is becoming an important part of modern information technology. It can not only change the way and content of information dissemination and processing but also improve people’s quality of life and meet the growing material and cultural needs of the people. This paper first introduces the basic structure, style characteristics, and development process of Russian modern oil painting, then expounds the application of Internet of things technology and artificial intelligence technology, and then uses the method of questionnaire to investigate the innovation and development of Russian modern oil painting. Finally, the survey shows that senior students know more about Internet of things technology, while applied majors know more than non-applied majors. The grade that knows the least is freshmen, which is related to the degree of exposure to professional knowledge. Students majoring in Russian modern oil painting can share their painting experience through the Internet of things, learn online painting resources through the Internet of things, and add extra income to their part-time painters through the Internet of things. However, due to the Limited breeding technology of students, a small number of students can be part-time online painters, and most students use the Internet of things for knowledge input. Senior students majoring in Russian modern oil painting know more about artificial intelligence, and junior and sophomore students have a general understanding of this field. Through research, the team proposed the innovative development of modern Russian oil painting under the background of Internet of Things and artificial intelligence for reference, and formed our own oil painting creation style by integrating a variety of techniques.

Published: May 2022

The world is filled with exciting technologies and ideas; scientists build machines to avoid human intervention in completing work. It is highly challenging to complete the task without the artificial intelligence (AI) technology intervention. With technological development, specific processes or consultations are performed with doctors available worldwide. In this scenario, it could be noticed that health care is one of the world’s expected domains that require the most incredible attention in data security while performing data transfer. Nodes in the network are considered based on the weakest link to overcome the cyber attacker’s issues. Besides building the software for data storage, a better mechanism has to be incorporated to provide security to the stored data. This process is a delicate task for every network engineer. This paper will explain such concepts related to health prediction and health care by building the most robust network security systems. The proposed optimized neural network representation is differentiated with the available data conclusive process. From the outcomes, it is observed that the suggested representation achieves an accuracy of 98.89%, which is 4.76% higher than the existing model.

Published: May 2022

Primary congenital glaucoma (PCG) is an ocular disease characterized by congenital anterior segmental maldevelopment with progressive optic nerve degeneration. Certain genes, such as cytochrome P450 family 1 subfamily B member 1 and latent TGF-β-binding protein 2, are involved in the pathogenesis of PCG, but the exact pathogenic mechanism has not yet been fully elucidated. There is an urgent need to determine the etiology and pathophysiology of PCG and develop new therapeutic methods to stop disease progression. Animal models can simulate PCG and are essential to study the pathogenesis and treatment of PCG. Various animal species have been used in the study of PCG, including rabbits, rats, mice, cats, zebrafish, and quails. These models are formed spontaneously or by combining with genetic engineering technology. The focus of the present study is to review the characteristics and potential applications of animal models in PCG and provide new approaches to understand the mechanism and develop new treatment strategies for patients with PCG.

Authors: Haddad Reza , Roostaie Ali
Published: May 2022

In this study, Cu20-polyoxotungstate [Cu20Cl(OH)24(H2O)12(P8W48O184)]25− supported on a magnetic substrate was used as a high-performance green method for the reduction of nitrophenol compounds such as 4-nitrophenol (4-NP) and 2,4,6-trinitrophenol (2,4,6-TNP). [Fe3O4@SiO2-NH2-Cu20P8W48] as heterogeneous magnetic nanocatalyst was synthesized and characterized by FT-IR, SEM, TEM, VSM, and TGA. This nanocatalyst has an excellent efficiency in the reduction of nitrophenol compounds to aminophenol compounds. The UV-Vis absorption spectrum is used at different times to evaluate the progress of the reaction. Under optimal conditions, 100% conversion and selectivity in reduction of 4-NP and 2,4,6-TNP to 4-AP and 2,4,6-TAP were obtained, respectively. In addition, after the reaction, the [Fe3O4@SiO2-NH2-Cu20P8W48] was recovered using an external magnetic field and used for the next cycle. The results showed that the nanocatalyst can perform eight consecutive cycles without any significant decrease in efficiency. In the end, according to the results, the proposed mechanism for this reaction was reported.

Published: May 2022

Objective. As the most commonly used drug in the world, aspirin has shown benefits for myocardial infarction, stroke, and vascular death in many secondary prevention trials and their meta-analysis. The purpose of this study was to evaluate the association between aspirin and its adverse reactions as a preventive drug using the FDA adverse event reporting system (FAERS). Methods. The FAERS database was queried for the adverse drug events (ADE) reported from the first quarter of 2004 to the second quarter of 2021. We counted and trended reports to FAERS in which aspirin was associated with anaphylaxis or anaphylaxis followed by death. Results. The search retrieved 858 aspirin-associated cases within the reporting period; 108 AE pairs with significant disproportionality were retained. The top 10 AE pairs associated with using aspirin for prophylaxis were melaena, duodenal ulcer, gastritis erosive, gastric ulcer hemorrhage, etc. The top 10 AE pairs for thrombosis prophylaxis were melaena, duodenal ulcer, microcytic anemia, lip erosion, vascular stent thrombosis, etc. The screened adverse event reports are classified and counted according to the system organ class (SOC); it mainly focuses on gastrointestinal disorders, general disorders, and administration site conditions. Among the 858 cases of aspirin used as prophylaxis medication in the FAERS database, the reporting areas were mainly in Europe and the Americas. Conclusion. Adverse drug reactions may occur in the clinical use of aspirin. It should strengthen patient medication education, pay close attention to adverse reactions, and adjust the administration method in time to ensure the safety of medication.

Published: May 2022

Stress, which refers to a combination of physiological, neuroendocrine, behavioral, and emotional responses to novel or threatening stimuli, is essentially a defensive adaptation under physiological conditions. However, strong and long-lasting stress can lead to psychological and pathological damage. Growing evidence suggests that patients suffering from mild and moderate brain injuries and diseases often show severe neurological dysfunction and experience severe and persistent stressful events or environmental stimuli, whether in the acute, subacute, or recovery stage. Previous studies have shown that stress has a remarkable influence on key brain regions and brain diseases. The mechanisms through which stress affects the brain are diverse, including activation of endoplasmic reticulum stress (ERS), apoptosis, oxidative stress, and excitatory/inhibitory neuron imbalance, and may lead to behavioral and cognitive deficits. The impact of stress on brain diseases is complex and involves impediment of recovery, aggravation of cognitive impairment, and neurodegeneration. This review summarizes various stress models and their applications and then discusses the effects and mechanisms of stress on key brain regions—including the hippocampus, hypothalamus, amygdala, and prefrontal cortex—and in brain injuries and diseases—including Alzheimer’s disease, stroke, traumatic brain injury, and epilepsy. Lastly, this review highlights psychological interventions and potential therapeutic targets for patients with brain injuries and diseases who experience severe and persistent stressful events.
Research on the Impact of Credit Support on the Income Increase of Family Farms in China: Based on Hunan Province
Authors: Luo Zhonghua , Zhou Mengliang
Published: May 2022

Family farms are an important part of rural revitalization in China. Strengthening credit support for family farms is of great significance for increasing family farm income. This paper takes 1895 demonstrative family farms in Hunan Province as an example and proposes research hypotheses based on the theoretical analysis of the income growth effect of family farm credit. Based on the Cobb–Douglas theory, the Tobit model is used to make an empirical analysis of the income-increasing effect of family farms. And, we can add explanatory variables and QTE quantile effect model for testing. The results show that strengthening family farm credit support is conducive to increasing family farm income, and the coef. is 0.428. Family farm credit support is positively correlated with its total operating income. The more credit support for a family farm receives, the higher its total operating income. When the credit support of a family farm reaches a certain scale of 300,000 RMB, its income-increasing effect begins to diminish gradually.
Anodal Transcranial Direct Current Stimulation (atDCS) of the Primary Motor Cortex (M1) Facilitates Nonconscious Error Correction of Negative Phase Shifts
Authors: Pollok Bettina , Jurkiewicz Martin , Krause Vanessa
Published: May 2022

Accurate motor timing requires the temporally precise coupling between sensory input and motor output including the adjustment of movements with respect to changes in the environment. Such error correction has been related to a cerebello-thalamo-cortical network. At least partially distinct networks for the correction of perceived (i.e., conscious) as compared to nonperceived (i.e., nonconscious) errors have been suggested. While the cerebellum, the premotor, and the prefrontal cortex seem to be involved in conscious error correction, the network subserving nonconscious error correction is less clear. The present study is aimed at investigating the functional contribution of the primary motor cortex (M1) for both types of error correction in the temporal domain. To this end, anodal transcranial direct current stimulation (atDCS) was applied to the left M1 in a group of 18 healthy young volunteers during a resting period of 10 minutes. Sensorimotor synchronization as well as error correction of the right index finger was tested immediately prior to and after atDCS. Sham stimulation served as control condition. To induce error correction, nonconscious and conscious temporal step-changes were interspersed in a sequence of an isochronous auditory pacing signal in either direction (i.e., negative or positive) yielding either shorter or longer intervals. Prior to atDCS, faster error correction in conscious as compared to nonconscious trials was observed replicating previous findings. atDCS facilitated nonconscious error correction, but only in trials with negative step-changes yielding shorter intervals. In contrast to this, neither tapping speed nor synchronization performance with respect to the isochronous pacing signal was significantly modulated by atDCS. The data suggest M1 as part of a network distinctively contributing to the correction of nonconscious negative step-changes going beyond sensorimotor synchronization.
Construction of an Intelligent Arrangement Model for Vocal Music Based on HPC Cluster Programming
Authors: Gong Tianzhuo , Han Chunli
Published: May 2022

We model in this paper the HPC cluster programming structure and perform a multidimensional computational analysis to design a vocal intelligent arrangement model based on HPC cluster programming using brilliant vocal arrangement. This paper proposes the construction scheme of the HPC interconnection simulation environment based on the full investigation of the research related to the construction of a supercomputer simulation environment at home and abroad. The rapid development of HPC technology has promoted the study of automatic music generation technology, which effectively avoids the traditional machine learning method of music. The rapid growth of HPC technology has facilitated the research of automated music generation techniques, which effectively avoids the overreliance of conventional machine learning methods on music rules and artificial design features. It achieves better results in complex music generation tasks. The key features of intelligent music arrangement are designed and implemented by summarizing the principles of converting paintings to music and then creating the rules of converting images to music and the corresponding relationships based on the theoretical basis. After the conversion rules are clarified, the specific design is carried out according to the computing process of the genetic algorithm. At the same time, the framework of the arrangement is combined with children’s aesthetic psychology; the evolutionary adaptation function is developed in combination with music theory, which finally ensures the motility of the generated music.
Energy-Aware Intrusion Detection Model for Internet of Vehicles Using Machine Learning Methods
Authors: Lihua Lu
Published: May 2022

With increasing development of Internet of Things (IoT) technology, wireless communications, big data, and smart applications, vehicular communications have become ubiquitous in smart cities, smart transportation systems, and Internet of Vehicles (IoV) environments. In this paper, a new Energy-aware Intrusion Detection System (EIDS) based on intelligent two-phase contract management model is presented for vehicle-to-vehicle (V2V) strategy in the IoV environments. In this strategy, the proposed EIDS predicts safe and energy-efficient end-to-end points for communication between existing vehicles in the IoV. The contract management process shows how the vehicles are connected together with a safe condition to transfer information. For prediction phase, a regression algorithm is applied to evaluate the proposed EIDS according to NSLKDD data set in the IoV environments. Simulation experiments show that the proposed regression-based EIDS strategy can effectively improve the accuracy and precision factors with 90% and 84%, respectively, and greatly minimize execution time by 4 seconds with respect to other machine learning algorithms.

Povos indígenas e cidadania: inscrições constitucionais como marcadores sociais da diferença na América Latina
Authors: Beltrão Jane Felipe , Oliveira Assis da Costa
Published: May 2022

Argentina, Brasil, Bolívia, Paraguai e Uruguai modificaram suas normas nacionais ao ratificarem tratados internacionais, pressionados pelo crescente protagonismo indígena na América Latina, desde os anos 70 do século passado. Contudo, nem sempre a noção de cidadania adotada incluiu o reconhecimento do direito à diferença como legítima garantia de igualdade de condições pela equivalência, dificultando a constituição de novos campos sociais e políticos que permitam aos povos indígenas ser cidadão pleno sem deixar de ser quem são. As inscrições constitucionais ainda são pautadas pelo formalismo que parece produzir mais um dos muitos marcadores sociais da diferença, sem considerar a prática plural, embora assegure direitos à pluralidade. Entretanto, o efeito da Constituição da Bolívia, deixa explícita não apenas a possibilidade do pluralismo jurídico, mas aponta a existência de reais condições para a construção de um Estado plural que contemple os marcadores sociais a sério.
As cidades da antropologia: Entrevista com Michel Agier

Published: May 2022

A trajetória de pesquisas de Michel Agier – professor e pesquisador na École des Hautes Études en Sciences Sociales (EHESS), coordenador de pesquisas no Institut de Recherche pour le Développement (IRD) e ex-diretor do Centre d’Études Africaines (Ceaf/ EHESS), todos sediados em Paris – configurou-se inicialmente na realização de etnografias em cidades africanas como Lomé (Togo) e Douala (Camarões) (Agier, 1983; 1999). Tais pesquisas são marcadas pelo seu interesse por situações urbanas que propiciam, segundo ele, um entendimento mais profundo acerca de aspectos que talvez não se apreenda senão na cidade. Isso ocorre porque os contextos citadinos são tomados como espaços relacionais onde se produzem fenômenos significativos e invenções culturais inéditas e não apenas justaposição de culturas (Agier, 2006, p.138-140).
Os Pretos do Carmo diante do possível, porém improvável: Uma análise sobre o processo de reconhecimento de direitos territoriais
Authors: Stucchi Deborah , Ferreira Rebeca Campos
Published: May 2022

As demandas inauguradas após a publicação do Art. 68 do Ato das Disposições Constitucionais Transitórias da Constituição Federal, relacionadas ao reconhecimento dos direitos territoriais de comunidades remanescentes de quilombos, representam oportunidade para refletir a respeito da emergência de novas categorias de sujeito de direitos e seus efeitos socioculturais e políticos, em várias escalas de aproximação, para os grupos em questão. Desde a sua publicação, em 1988, até o momento, 21 anos depois, tem-se refletido pouco a respeito dos impactos dos processos de reconhecimento sobre o cotidiano dos grupos beneficiados. objetivo deste texto é partir do conjunto de referências obtidas no âmbito dos estudos antropológicos realizados no Carmo – bairro negro localizado no município de São Roque, interior de São Paulo – para discutir como as exigências impostas pela regulamentação deste direito, formalizadas nas normas internas de órgãos públicos responsáveis pela execução da política de identificação e reinterpretadas nas falas e práticas de funcionários, técnicos ou burocratas, fixam determinados limites que se sobrepõem às formas de organização, representação e decisão próprias desses grupos.

O candomblé (barroco) de Roger Bastide
Authors: Peixoto Fernanda Arêas
Published: May 2022

Este artigo propõe uma releitura de Imagens do Nordeste místico em branco e preto (1945), de Roger Bastide, à luz de outros textos que ele publicou na imprensa paulistana, na mesma década de 1940. Trata-se de artigos que examinam a arte popular e a arte moderna, as cidades e a arquitetura, nos quais ele esboça uma reflexão sobre o barroco brasileiro, distinta das análises sociológicas do barroco que empreendera em seus ensaios de feitio mais acadêmico. O exame desse conjunto evidencia que, desde o momento de sua chegada ao Brasil em 1938, Bastide realiza pesquisas simultâneas sobre o barroco e sobre o candomblé. Esses dois grandes temas de interesse do autor, explorados lado a lado, longe de revelarem interesses divergentes, se entrecruzam, um esclarecendo o outro. E mais: o barroco não apenas constitui uma das matérias de análise de Bastide, como fornece elementos decisivos para que ele ajuste sua visada crítica.
Pierre Clastres ou uma Antropologia contra o Estado

Esta entrevista foi realizada na recém-inaugurada nova sede do Programade Pós-Graduação em Antropologia Social da Universidade Federaldo Amazonas, na cidade de Manaus/AM, em dezembro de 2011. JoãoPaulo Lima Barreto é indígena da etnia Tukano e, no momento, desenvolvesua pesquisa de mestrado sobre as formas de conhecer ocidentaisdo ponto de vista dos Tukano. Este malabarismo entre regimes deinteligibilidade não é novidade para João Paulo, que lida com a questãodesde o momento em que deixou sua aldeia de origem no Rio Tiquié,no Alto Rio Negro, para estudar no colégio de missionários, afastandosedo aprendizado que vinha tendo com seu avô sobre os conhecimentosindígenas.João Paulo narra sua trajetória intelectual no sentido mais amplopossível, passando pela chegada à cidade, o trabalho no garimpo e o ingressono ensino superior, bem como suas buscas na filosofia e no direitoaté, finalmente, acreditar ter encontrado a possibilidade do diálogoentre as formas de conhecer indígenas e não-indígenas na antropologia.Conta-nos também sobre a criação e consolidação do Colegiado Indígena,peça fundamental em seu experimento de equilibrista conceitual.O Colegiado foi criado pelos alunos dos programas de pós-graduaçãoem Antropologia Social e em Sociedade e Cultura na Amazônia da UFAM,conjuntamente com os alunos do curso de Pedagogia Intercultural daUniversidade do Estado do Amazonas (UEA). Sua proposta é viabilizara troca de experiências entre os alunos indígenas de ambas as universidadese promover discussões acadêmicas sobre a prática do conhecimentoindígena no âmbito dos programas de pós-graduação. Outro objetivoque perpassa o interesse do grupo é o de proporcionar a produção deconhecimento indígena nas universidades por meio da produção de artigos,livros, matérias para sites e, principalmente, da execução de encontrosque visem à propagação desse conhecimento no âmbito acadêmico.Enquanto conversávamos, João Paulo aguardava ansiosamente a chegadade seu pai e seu irmão, respeitados conhecedores tukano.

Considerando-se os missionárioscomo “tradutores”, procuraremos elucidar as maneiras como os seusdiscursos se apropriaram e produziram as diferenças nativas. Para tanto, recuperaremosparte da análise que realizamos dos escritos etnográficossalesianos a respeito das populações indígenas no Brasil entre 1920 e 1970em obra recentemente publicada.
As vicissitudes da fama: os dons divinos e os pactos demoníacos entre os tocadores de viola de dez cordas do norte e noroeste mineiro
Authors: Pereira Luzimar Paulo
Published: May 2022

As narrativas sobre pactos demoníacos são importantes tópicosda vida social dos violeiros do norte e noroeste de Minas Gerais. Por umlado, elas apresentam, passo a passo, as regras de consecução dos pactos,apontando os lugares, os momentos e os objetos mais adequados à sua execução.Verdadeiras “receitas”, os relatos guardam todos os saberes relativosaos contatos com o diabo. Por outro lado, as narrativas também destacam ocaráter supostamente factual dos eventos. Para todos os efeitos, as históriastratariam de casos ocorridos com alguém, num lugar e numa época peculiares.Pretendo observar como as histórias de supostos pactários se articulampara construir a figura pública de um tocador. Meu argumento é o de que osrelatos são eventos responsáveis por engendrar um campo específico de disputasonde os violeiros e seus aliados se enfrentam em torno de reputações.

Two new varieties of Russula Pers. (Basidiomycota: Russulaceae) from Sal forests of Shiwaliks, India
Authors: Jitender Kumar  , Narender Singh Atri
Published: May 2022

This paper deals with two new varieties of Russula species, R. camarophylla var. reticulospora var. nov. and R. aurea var. minuta var. nov. These were collected from the Shiwalik range of northwestern India, in association with Shorea robusta. Russula aurea var. minuta differs from R. aurea in having small sized sporophores, dentate to wavy gill edges with golden or yellow deposition instead of smooth and much smaller spores. Whereas, mushroom R. camarophylla var. reticulospora is close to Russula camarophylla except for the larger carpophores that have white cream pileus surface and larger spores. In basidiospores warts are connected to form mostly complete reticulum instead of mostly isolated warts reported in Russula camarophylla. In view of the presence of some unique varied features in the presently examined collections two new varieties of Russula has been proposed.
Targeting Microtubules for the Treatment of Heart Disease
Authors: Warner Emily F. , Li Yang , Li Xuan
Published: May 2022

Heart disease remains the leading cause of morbidity and mortality worldwide. With the advancement of modern technology, the role(s) of microtubules in the pathogenesis of heart disease has become increasingly apparent, though currently there are limited treatments targeting microtubule-relevant mechanisms. Here, we review the functions of microtubules in the cardiovascular system and their specific adaptive and pathological phenotypes in cardiac disorders. We further explore the use of microtubule-targeting drugs and highlight promising druggable therapeutic targets for the future treatment of heart diseases.
Arrhythmias as Presentation of Genetic Cardiomyopathy

Published: May 2022

There is increasing evidence regarding the prevalence of genetic cardiomyopathies, for which arrhythmias may be the first presentation. Ventricular and atrial arrhythmias presenting in the absence of known myocardial disease are often labelled as idiopathic, or lone. While ventricular arrhythmias are well-recognized as presentation for arrhythmogenic cardiomyopathy in the right ventricle, the scope of arrhythmogenic cardiomyopathy has broadened to include those with dominant left ventricular involvement, usually with a phenotype of dilated cardiomyopathy. In addition, careful evaluation for genetic cardiomyopathy is also warranted for patients presenting with frequent premature ventricular contractions, conduction system disease, and early onset atrial fibrillation, in which most detected genes are in the cardiomyopathy panels. Sudden death can occur early in the course of these genetic cardiomyopathies, for which risk is not adequately tracked by left ventricular ejection fraction. Only a few of the cardiomyopathy genotypes implicated in early sudden death are recognized in current indications for implantable cardioverter defibrillators which otherwise rely upon a left ventricular ejection fraction ≤0.35 in dilated cardiomyopathy. The genetic diagnoses impact other aspects of clinical management such as exercise prescription and pharmacological therapy of arrhythmias, and new therapies are coming into clinical investigation for specific genetic cardiomyopathies. The expansion of available genetic information and implications raises new challenges for genetic counseling, particularly with the family member who has no evidence of a cardiomyopathy phenotype and may face a potentially negative impact of a genetic diagnosis. Discussions of risk for both probands and relatives need to be tailored to their numeric literacy during shared decision-making. For patients presenting with arrhythmias or cardiomyopathy, extension of genetic testing and its implications will enable cascade screening, intervention to change the trajectory for specific genotype-phenotype profiles, and enable further development and evaluation of emerging targeted therapies.
Cardiorenal Nexus: A Review With Focus on Combined Chronic Heart and Kidney Failure, and Insights From Recent Clinical Trials
Authors: McCullough Peter A. , Amin Alpesh , Pantalone Kevin M. , Ronco Claudio
Published: May 2022

The cardiorenal nexus encompasses a bidirectional relationship between the heart and the kidneys. Chronic abnormalities in cardiac function can lead to progressive kidney disease, and chronic kidney disease can lead to progressively decreasing cardiac function and increasing risk of cardiovascular disease, including heart failure. About 15% of US adults have chronic kidney disease, 2% have heart failure, and 9% have cardiovascular disease. Prevalence rates of chronic kidney disease, cardiovascular disease, and associated morbidities such as type 2 diabetes are expected to increase with an aging population. Observational studies provide evidence for the cardiorenal nexus. Follow‐up data from placebo arms of clinical trials in chronic kidney disease or cardiovascular disease show higher rates of renal and cardiovascular outcome events in patient subgroups with type 2 diabetes than in those without type 2 diabetes. The cardiorenal syndromes develop along an interlinked pathophysiological trajectory that requires a holistic, collaborative approach involving a multidisciplinary team. There is now a compendium of treatment options. Greater understanding of the underlying pathophysiology of the cardiorenal nexus will support optimization of the management of these interlinked disease states.
Taxonomic studies on the genus Sanicula (Apiaceae) from China (Ⅱ): The clarification of some morphological distinction between S. orthacantha var. orthacantha and S. orthacantha var. brevispina, with the reduction of S. petagnioides to the synonymy of the former, and S. orthacantha var. stolonifera to the synonymy of the latter variety

Published: May 2022

Based on observations on living plants in field, together with examination of herbarium specimens (including type material), we demonstrate that Sanicula orthacantha var. orthacantha (Apiaceae) differs from S. orthacantha var. brevispina only by the rhizome short, oblique rootstock bearing elongated, fibrous roots, sometimes fleshy stoloniferous (vs. slender, elongate and lignified nodes stoloniferous). In addition, S. petagnioides is found to be identical with S. orthacantha var. orthacantha, and S. orthacantha var. stolonifera is found to be identical with S. orthacantha var. brevispina, we therefore synonymized herein respectively. Lectotypification is proposed for S. petagnioides, S. orthacantha var. stolonifera.
Rudgea infundibuliformis (Palicoureeae, Rubiaceae), a new species from Southeastern Brazil
Authors: BRUNIERA CARLA P. , COSTA IDIMÁ G. , ZAPPI DANIELA C.
Published: May 2022

A new species of Rudgea (Rubiaceae) was discovered in a forest remnant in the state of Rio de Janeiro, Brazil, within the Atlantic Rainforest, and is distinguished by its relatively small leaves, reduced inflorescences, and the broadly infundibular, externally densely tomentose corolla. Rudgea infundibuliformis is categorized as Critically Endangered, and is known so far from a single locality, the “Mata do Quimbira”, in the municipality of Italva. This rare species is probably related to other species of the Jasminoides informal Group, sharing characters as the leaf blade with axillary domatia in the secondary veins beneath, terminal and pedunculate inflorescences, lobed calyx, infundibular corolla, and ripe fruits orange or red.
Rhodiola yushuensis, a new species of Rhodiola (Crassulaceae) from Qinghai, China
Authors: RONG YU-LIN , LI GUO-DONG , ZHENG HAI-LEI , ZHANG JUN , MENG SHI-YONG
Published: May 2022

A new species from the Qinghai-Tibetan Plateau is described and illustrated. Rhodiola yushuensis S.Y. Meng et J. Zhang sp. nov. is similar to Rhodiola smithii (Hamet) S. H. Fu, but it differs in its inner caudex leaves with obvious petioles and the leaf blades are obovate-triangular (vs. inner caudex leaves with strongly descends to the base of the petiole, and the leaves are long linear) and the outer caudex leaves are scalelike, triangular-suborbicular (vs. scalelike, narrowly triangular). Principal component analysis (PCA) analysis of the leaf traits and seed coat architecture also showed that R. yushuensis can be separated from R. smithii. The nrDNA internal transcribed spacer (ITS) sequences also support the claim that this plant is a new species, and it is grouped with R. smithii.
Description of two new species of the genus Glyphiulus Gervais, 1847 (Diplopoda: Spirostreptida: Cambalopsidae) from southern China
Authors: JIANG XUAN-KONG , CHEN HUI-MING , XIE ZHI-CAI
Published: May 2022

Two new species of the millipede genus Glyphiulus Gervais, 1847 are described from southern China: Glyphiulus fortis sp. nov. and Glyphiulus hainanensis sp. nov. Glyphiulus fortis sp. nov. is cavernicolous, vs. G. hainanensis sp. nov. which was collected from an epigean environment. Both of them belong to the G. javanicus-group. Additionally, DNA barcoding and phylogenetic analyses based on nucleotide sequences of COI and 16S of the two new species, as well as their allied species were conducted. The morphological characteristics, the genetic distances and the phylogenetic tree revealed that the two new species are unambiguously distinct from their congeners.
