Authors: Lian GuoHua
Published: September 2022

Lack of trust, lack of standards, and low efficiency are the three biggest problems in China’s trade financing at present. With the development and application of new generation technologies such as big data, cloud computing, artificial intelligence, and blockchain technology, China is in the stage of financial technology 3.0 under the deep integration of finance and technology. In the field of financial technology, the most concerned is the application of blockchain technology in trade finance business. With the successive construction of various blockchain platforms and the acceleration of the internationalization process, the international trade credit risk behind it is also increasing. Among many financial services, trade finance is the most closely integrated field with blockchain technology. In this context, preventing the risks in the business process of international trade enterprises, so as to reduce the cost of financial transactions, improve the effectiveness of financial services, and better serve the real economy is not only the internal development needs of enterprises, but also the national financial strategy needs. In view of the above problems, this paper analyzes the risk factors faced by multinational trading enterprises in the transaction process through the transaction data of some multinational enterprises on mobile phones, and constructs a credit evaluation system of international trading enterprises based on blockchain, in order to enhance the trade risk resistance ability of international trading companies.

In this study, the dynamic mechanical spectroscopy was used to characterize the effects of minor Ni addition on the relaxation behavior of ZrCoAl bulk metallic glass (BMG). For this purpose, the Kohlrausch–Williams–Watts (KWW) function and quasi-point defect (QPD) model were used for evaluation of relaxation under the different aging temperatures. The results indicated that the Ni addition shifted the relaxation process to the higher temperatures. Moreover, the estimations showed that the activation energy of relaxation was 5.951 eV and 6.205 eV for ZrCoAl and ZrCoAlNi, respectively. It was also revealed that the microalloying process enhanced the structural defects in the system and led to the improvement of dynamic heterogeneity in the BMG. Comparing the physical models, it is suggested that a small change in the structural defects intensifies the dynamic heterogeneity in the material.

Patients with breast cancer frequently experience psychological distress. This study aimed to investigate the effect of narrative nursing on middle-aged patients with breast cancer. In all, 82 patients with breast cancer admitted to the Affiliated Hospital of Nantong University were divided into two groups, namely, the observation group and the control group, by simple random sampling, with 41 cases in each group. The patients in both groups were treated with breast cancer surgery. Additionally, the control group received routine nursing, whereas the observation group received narrative nursing based on the control group. After 8 weeks of nursing, the SAS (self-rating anxiety scale) and SDS (self-rating depression scale) scores in the observation group were lower than those in the control group (

Published: September 2022

Osteochondroma is a relatively common benign tumor of the bone, and compressive neuropathies due to osteochondroma are comparatively rare. Here, we present a rare case of osteochondroma of the fibular head that caused peroneal nerve palsy in an 8-year-old girl. Physical examination revealed 0/5 tibialis anterior, 1/5 extensor hallucis longus, and 1/5 peroneal brevis muscle power—according to the manual muscle testing grading system, as well as numbness on the lateral side of the right leg and the back of the foot. Radiological examination and ultrasound revealed a bone tumor in the head of the right fibula. Magnetic resonance imaging ruled out spinal nerve root compression. It was discovered that the bone tumor in the fibular head had compressed and displaced the common peroneal nerve. The patient underwent surgical decompression of the right peroneal nerve. A bone region measuring

 mm was removed. Three months postoperatively, the preoperative neurological deficits were found to be nearly resolved. The patient presented with a foot drop for 1 year, but symptoms resolved 3 months after surgery. Conventional wisdom states that surgery should be performed within 3 months, but we recommend that surgery be performed as soon as diagnosis is made even in cases with a long history, as it may improve patient symptoms and outcomes.

Objective. This study was designed to establish quality standards of Burnet gels and investigate the effects and mechanism of Burnet gels on steroid‐dependent dermatitis (HDD) in guinea pigs. Methods. HPLC was used to determine the content of gallic acid, Gentiopicrin, and paeonol. A total of 48 male guinea pigs were recruited and randomly divided into control group, model group, tacrolimus ointment group, and Burnet gel group (Low, medium, and high concentration). The HDD guinea pig model was established by the 0.5% clobetasol propionate tincture. After HDD model establishment, control group and model group smeared normal saline and the rest of the group with corresponding drugs for three weeks. The contents of IFN‐γ, IL‐4, and IgE in the guinea pig serum were detected by the ELISA; the protein expression levels of FLG, LOR, and Caspase‐14 in the epidermis of guinea pigs were detected by the immunohistochemical and Western blotting method. Results. The content of gallic acid, Gentiopicrin, and paeonol was 0.30 mg/g, 1.06 mg/g, and 0.56 mg/g. Compared with the normal group, the IFN‐γ, IL‐4, and IgE of guinea pig serum in the model group were significantly increased; the FLG, LOR, and Caspase‐14 of guinea pig epidermis in the model group were significantly decreased; compared with the model group, the IFN‐γ, IL‐4, and IgE of guinea pig serum in the tacrolimus ointment group and Burnet gel group were significantly decreased; the FLG, LOR, and Caspase‐14 of guinea pig epidermis in the tacrolimus ointment group and Burnet gel group were significantly increased. Conclusion. Burnet gels can improve guinea pig HDD model, and the mechanism may be related to inhibiting skin inflammation and promoting the formation of epidermal skin barrier.

Published: September 2022

Massive multiple-input multiple-output (MIMO) systems based on millimeter-wave (mmWave) technology commonly utilize a combination of hybrid analog and digital signal processing to reduce the number of radiofrequency (RF) chains, cutting down the hardware costs and power consumption. The subconnected structure is one of the architectures that realize hybrid analog and digital processing, in which each RF chain is connected to a subset of antennas through phase shifters so as to reduce the implementation complexity. In this paper, we investigate the best subconnected structure design for mmWave massive MIMO systems. First, we formulate the optimization problem based on a simplified connection model. Next, we derive a suboptimal solution in closed form by leveraging the mmWave channel characteristics and discuss the impact of different connection parameters on the spectral efficiency. The spectral efficiency is closely related to the structure of the analog processing and the interantenna spacing. When the interantenna spacing is an even a multiple of half wavelength, the localized structure, i.e.,

i
=
1

achieves the maximum spectral efficiency. When the interantenna spacing is an odd multiple of half wavelength and the analog processing is accomplished by

i
=

interleaved structure, the best performance is obtained. Numerical results demonstrate the correctness of the theoretical analysis.

Authors: zhang Kaiwu , Du Dengxiang , Wang Wei
Published: September 2022

Embryogenic and regenerable tissue cultures are widely used in plant transformation. To dissect the molecular mechanism of embryogenesis, we used inbred line A188 as the material; the immature embryo of kernels (15 day after pollination, 15DAP) was isolated and cultured in inducing medium and subjected to RNA-Seq. The results revealed that 5,076 differentially expressed genes (DEGs) were involved in morphological and histological changes and endogenous indole-3-acetic acid (IAA) alteration. Functional analysis showed that the DEGs were related to metabolic pathways and biosynthesis of secondary metabolites. In particular, ARF16 and ARF8 genes of auxin response factors (ARF) were upregulated from EC to IDC and EC to IRC. Meanwhile, BBM2, SERK1, and SERK2 genes of the embryogenic pathway were upregulated, and WIP2 and ESR genes of the wound-inducible were upregulated from EC to IDC and EC to IRC. These changes can improve conversion efficiency from EC to IRC, which is important for elucidating the underlying molecular mechanisms of callus formation.

The major setback faced by any of the production industry was maintaining the surface quality and dimensional accuracy of parts manufactured. Higher productivity is expected from industrial point of view, but resulting in poor surface texture. This work aims at addressing this problem by developing a suitable damping system for increased production with high precision products. In conventional method, dampers used is assembled of many parts, whereas the innovation in this paper is that the damper structure is monolithic in nature. Hence, manufacture time and cost of new innovative compliant damper is reduced. The work addressed the problem of damping by the use of compliant mechanism developed through building blocks of planar compliant mechanisms synthesis. Finite element analysis (FEA) was carried out in deciding the final form of the damping system. The proposed design was created by following fused deposition modelling (FDM 3D printing technique) using acrylonitrile butadiene styrene (ABS) material. Based on the results obtained from the experiments, the damping system has an impact on the surface quality of the product. The cutting force produced between the cutting edge and work surface could be improved by providing continuous contact (i.e., higher tool stability). The tool stability could be improved by using the compliant damping design and 3D printing technology for developing the complex designs into real products. The major limitation of the proposed work is the complexity in analysing compliant models with all the boundary conditions prevailing in the real time environment. The major influencing boundary conditions could be applied in neglecting insignificant factors. This work is a novel approach for developing a compliant mechanism-based damper that could restrict the effects of chatter in machining operation. The building blocks-based design was produced using 3D printing of the ABS material. Turning of aluminium was analysed for surface improvement by the tool stability improvement. Results revealed the impact of the ABS compliant damper. On an average, surface roughness of the products was reduced by 27.61%.

Published: September 2022

The underwater vehicle manipulator system is a powerful tool for the exploration and development of marine resources. Due to the complexity of the marine environment, there are many disturbance factors and difficult to control. Taking the fixed depth control in hovering mode as an example, the vertical plane decoupling control model is established, and the adaptive sliding mode control method based on the disturbance observation is studied. The nonlinear disturbance observation is used to estimate the external unknown disturbance in real time, and the adaptive sliding mode method is used for compensation control. Simulation results show that the control method can effectively compensate for the sudden disturbance term, does not produce obvious trim motion, has strong robustness, and provides a reliable and stable base for the operation of the underwater manipulators. Finally, the operation experiments in the pool and real sea area under the disturbance condition are carried out, respectively. The experimental results show that the control effect is good and the stability is greatly improved compared with the traditional control method.
Simulation of Fatigue Fracture Detection of Bridge Steel Structures under Cyclic Loads
Authors: Yang Dangfeng , Yao Lixiao , Pang Qi
Published: September 2022

Bridge steel structures are widely used in bridge construction with the advantages of light self-weight, convenient use, and good bridge span. Steel bridges are subjected to cyclic loading for a long time during their service period, and cyclic loading has a certain influence on their fatigue resistance performance. Fatigue is a phenomenon in which the structure is subjected to cyclic loading that generates cracks, expands continuously, and eventually leads to fracture of the member. The bridge steel structure under the repeated action of vehicle load and cyclic load is caused by microcracks and will expand with time, and the bridge deck system structure is prone to fatigue damage, so fatigue fracture detection has a great impact on the safe service life of steel bridges. In this paper, the fatigue design guidelines in the relevant codes and the bridge steel structure detection model are compared and analyzed, and a neural network-based fatigue fracture detection model for bridge steel structures under cyclic loading is proposed for the study of fatigue and corrosion interactions and fatigue and fracture of steel bridges under complex stress conditions. For this purpose, in the relevant experiments, experiments are designed to detect the fatigue fracture of bridge steel structures under different cyclic loads, and the experimental results prove the effectiveness of the proposed method.
Analysis of the Low-Carbon, Environmental-Friendly, Energy-Saving, and Emission-Reduction Evaluation Model of Urban Rail Transit Based on the Spatiotemporal Distribution of Passenger Flow
Authors: Zhang Hong
Published: September 2022

The development of the urban economy and the effect of linkage radiation are inseparable from the urban transportation system’s efficient operation. In the context of the new era, environmental pollution caused by economic development has gradually become an invisible killer that endangers human health and the atmospheric environment. It is a pillar industry of economic development, a key part of urban infrastructure construction, and a necessary guarantee for urban residents to travel and live, and it is important to develop a low-carbon, environmental-friendly, energy-saving, and emission-reduction potential for urban transportation systems. On the basis of a large number of literature research, this paper attempts to establish the role of an urban rail transit system in energy conservation and emission reduction in three aspects: residents’ travel behavior, ground transportation operation, and low carbon, energy conservation, and reduced emission under the influence of the urban rail transit system. Based on the temporal and spatial distribution characteristics of urban rail transit passenger flow, a relatively complete energy-saving and emission-reduction evaluation model is established. Through case analysis, it is verified that the model can effectively evaluate the effect of energy saving and emission reduction under different rail transit settings and its spatial and temporal distribution characteristics, and provides ideas and technical guidance for multidimensional quantitative analysis of urban rail transit carbon environmental protection, energy conservation, and emission reduction.

Authors: Zhang Xiaodong , Guo Chunrong
Published: September 2022

Product development and innovation is the key issue for cross-border e-commerce operation. It is of great importance to build an intelligent open innovation system and maximize its proximity to market demand with the internationalization and digital advantages of cross-border e-commerce. Cross border e-commerce data is widely distributed among each node enterprise in the supply chain. But the enterprises will not share private data for intelligent learning for the sake of data security, which has become a difficulty problem in intelligent decision-making of open innovation. This paper analyzes the research status of open innovation and the technical basis of federated learning, builds an open innovation intelligent decision-making model of cross-border e-commerce based on federated learning, trains and tests the model using data from two participants, compares the intelligent prediction effects among whole learning, local learning and federated learning, and puts forward the collaborative promotion strategy of open innovation and intelligent optimization of cross-border e-commerce based on federated learning.

Tumor-infiltrating B and plasma cells (TIB) are prevalent in lung adenocarcinoma (LUAD); however, they are poorly characterized. We performed paired single-cell RNA and B-cell receptor (BCR) sequencing of 16 early-stage LUADs and 47 matching multiregion normal tissues. By integrative analysis of ∼50,000 TIBs, we define 12 TIB subsets in the LUAD and adjacent normal ecosystems and demonstrate extensive remodeling of TIBs in LUADs. Memory B cells and plasma cells (PC) were highly enriched in tumor tissues with more differentiated states and increased frequencies of somatic hypermutation. Smokers exhibited markedly elevated PCs and PCs with distinct differentiation trajectories. BCR clonotype diversity increased but clonality decreased in LUADs, smokers, and with increasing pathologic stage. TIBs were mostly localized within CXCL13+ lymphoid aggregates, and immune cell sources of CXCL13 production evolved with LUAD progression and included elevated fractions of CD4 regulatory T cells. This study provides a spatial landscape of TIBs in early-stage LUAD.

Significance:

While TIBs are highly enriched in LUADs, they are poorly characterized. This study provides a much-needed understanding of the transcriptional, clonotypic states and phenotypes of TIBs, unraveling their potential roles in the immunopathology of early-stage LUADs and constituting a road map for the development of TIB-targeted immunotherapies for the treatment of this morbid malignancy.

Melanoma is a cancer of melanocytes, with multiple subtypes based on body site location. Cutaneous melanoma is associated with skin exposed to ultraviolet radiation; uveal melanoma occurs in the eyes; mucosal melanoma occurs in internal mucous membranes; and acral melanoma occurs on the palms, soles, and nail beds. Here, we present the largest whole-genome sequencing study of melanoma to date, with 570 tumors profiled, as well as methylation and RNA sequencing for subsets of tumors. Uveal melanoma is genomically distinct from other melanoma subtypes, harboring the lowest tumor mutation burden and with significantly mutated genes in the G-protein signaling pathway. Most cutaneous, acral, and mucosal melanomas share alterations in components of the MAPK, PI3K, p53, p16, and telomere pathways. However, the mechanism by which these pathways are activated or inactivated varies between melanoma subtypes. Additionally, we identify potential novel germline predisposition genes for some of the less common melanoma subtypes.

Significance:

This is the largest whole-genome analysis of melanoma to date, comprehensively comparing the genomics of the four major melanoma subtypes. This study highlights both similarities and differences between the subtypes, providing insights into the etiology and biology of melanoma.

Avaliação da composição química de um óleo de copaíba (Copaifera spp.) e seu efeito em células-tronco mesenquimais
Authors: Maurmann Natasha , Lund Daniela Guerra , Pereira Daniela Pavulack , Pranke Patricia
Published: September 2022

A oleorresina obtida de copaíferas é amplamente utilizada na medicina tradicional brasileira. Este estudo avaliou a composição química por Cromatografia Gasosa (CG) e o efeito da oleorresina de Copaifera officinalis em células-tronco. Para isso as células foram tratadas com a oleorresina nas concentrações de 0,5, 20, 110, 140, 170 ou 200 µg/ml por 24h. A avaliação por CG identificou os sesquiterpenos β-cariofileno, trans-α-bergamoteno e óxido de cariofileno II como os compostos majoritários da oleorresina. As menores concentrações de oleorresina utilizadas apresentaram resultados semelhantes ao grupo controle e as maiores concentrações diminuíram significativamente a viabilidade celular e apresentaram maior citotoxicidade. Como conclusão, os principais componentes encontrados na oleorresina de copaíba foram os sesquiterpenos e as baixas concentrações testadas não foram citotóxicas. O aumento das concentrações de oleorresina de copaíba promoveu diminuição da viabilidade celular e aumento dos efeitos citotóxicos nas células-tronco. Embora a oleorresina de copaíba tenha uso etnofarmacológico na cicatrização, este estudo demonstrou efeito citotóxico em células-tronco, as quais estão relacionadas ao processo de regeneração corpóreo. Portanto, deve-se ter cuidado com a dosagem de oleorresina a ser utilizada, uma vez que este estudo in vitro mostrou citotoxicidade e um impacto negativo na viabilidade das células-tronco nas mais altas concentrações testadas.
M-Wallet Adoption in Emerging Markets: A Combination of Technological, Behavioral and Financial Aspects in a Rational Choice Model
Authors: Le Long Hoang , Duong Giang Huong , Nguyen Sang Minh
Published: September 2022

The adoption of mobile wallets can help to advance financial inclusion and human development in emerging countries. Current literature on mobile wallet (m-wallet) adoption focuses on technological and behavioral aspects, but neglects the financial aspect, which highly influences the decision-making of low-income people. This study identified the impacts of all three aspects on m-wallet adoption behavior by including behavioral technology acceptance factors and financial-related factors into a research framework derived from rational choice theory. Drawing data from 214 respondents across four emerging countries, the findings reveal the positive effects of perceived ease of use, perceived usefulness, and network externalities on m-wallet adopting intention. Regarding financial factors, while perceived risk negatively affects adopting intention, the effect of price value on adopting intention is not confirmed. Finally, financial literacy is found to have both positively direct and moderating effects on the relationship of perceived risk and users’ adopting intention.
Non-Inclusive Trade Unionism in the Tea Estates in Assam
Authors: Duara Mridusmita , Mallick Sambit
Published: September 2022

The state of Assam alone produces nearly 53 percent of the total tea production in India. Around one million workers are engaged in the tea industry in India. Tea – as a commercial product first cultivated and expanded by the British – is an outcome of the toil and struggle of the Adivasi workers or indigenous people of central and east India who were made to migrate to Assam under extremely brutal conditions, and they form one of the most oppressed communities in the state. This section of the population has been waging struggles to protect its rights in the state. Tea production is a labor-intensive enterprise in which trade unions should ideally play an assertive role at every stage. However, trade unions in the tea estates are gradually being questioned on their functionality in shaping industrial relations and upholding the rights of the workers. The key respondents, comprising plantation workers, trade union members, owners of the tea estates, and management staff, belong to the major tea producing districts of Assam: Dibrugarh, Sibsagar, Jorhat, Golaghat, Sonitpur, and also the lesser producing district, Kamrup. The present study ascertains the role of trade unions in dealing with the key issues faced by plantation workers, such as non-inclusion of women workers and casual workers and its failure to play an effective role in the negotiation or collective bargaining process with management and the state. It is observed that the trade unions function under the principles of the political parties and acquisition of political power is their sole motto.

Published: September 2022

Developing oil-dependent countries, like Oman, have growing potentials to broaden their export base aside from the hydrocarbon sector, thus enhancing economic growth. The article aims to identify factors to enhance Oman non-oil exports to the COMESA countries with a focus on innovations and trade facilitation. At the macro level, the article uses country trade data to explore the determinants of trade. At the firm level, the focus is on firm export behavior and innovation. Results show the key role of trade facilitation and firm-level innovations in particular at the commodity level. Innovation is significant and positive for commodities like vegetables, plastic, hides, stone, glass, and machinery. Government’s policies to boost exports and enhance economic growth should be geared to reducing market risks facing exporting firms as well as rewarding innovative companies through better innovation-targeted policies.
Phylogenetic relationships of the genera of Epipsocetae (Psocoptera: Psocomorpha)
Authors: GONZÁLEZ JOSÉ A.C.
Published: September 2022

The phylogenetic relationships of the genera of Epipsocetae were inferred on the basis of 122 morphological characters of adult specimens, corroborating the monophyly of the group with ten synapomorphies. The genera are grouped in well defined clades consistent at family level. Dolabellopsocidae, Ptiloneuridae and Epipsocidae are recognized as monophyletic families. In each family, the genera appear as monophyletic units, except in Epipsocidae, where the relationships are ambiguous and monophyly of most genera is not supported. Results indicate that Cladiopsocidae is paraphyletic; it was divided into two monophyletic families: Spurostigmatidae and Cladiopsocidae (sensu stricto), represented by the genera Spurostigma and Cladiopsocus respectively. Neurostigma is recognized as a monophyletic genus closely related to other epipsocid genera, nevertheless due to the low resolution obtained within Epipsocidae, it is not possible to decide if it is a genus of that family or if it forms a different clade at family level. The genera Parepipsocus Badonnel, previously considered as incertae sedis, and Dimidistriata Li & Mockford, previously placed tentatively in Dolabellopsocidae, are included in Epipsocidae. Loneuroides, Terryerwinia and Timnewia are recognized as valid genera. Two well defined clades are recognized within E pipsocidae, one with exclusively American genera, and the other that includes Asiatic and American genera.

Tityus martinpaechi Lourenço, 2001 was described based on a single adult female collected in the state of Ceará, Brazil. Subsequently, several scorpions of the genus Tityus were collected in the Chapada de Ibiapaba, Ceará, and sent to the Instituto Butantan in São Paulo, Brazil. One female and one male of these scorpions were identified as belonging to the species T. martinpaechi. Since the male of this species is yet unknown, it is described in this paper.
Referral of the Halocypridina Thaumatocypris (Miocene, Australia) to the Cladocopina (Ostracoda, Halocyprida)

B. K. Nadeau in 1955 identified as Thaumatocypris ostracodes from the middle Miocene Glenample Clay of Victoria, southeastern Australia. Nadeau’s collection of Ostracoda from the Glenample Clay was located in the collections of the Museum of Victoria, Melbourne. Examination of that material indicates that the Glenample Clay specimens attributed by Nadeau to Thaumatocypris belong to Polycope sanctacatherinae Whatley & Downing 1983. As a result, it is concluded that Thaumatocypris has not been collected in the Miocene of Australia. Furthermore, in a broader biostratigraphic/palaeobiogeographic context, the result confirms that no member of the Suborder Halocypridina has been reported so far from the Tertiary Period.

This paper reports the occurrence of 11 species of edaphic mites of the family Ascidae collected from soil and litter in southeastern Brazil. Five are new to science, namely Cheiroseius neophalangioides sp. nov., Gamasellodes magniventris sp. nov., Lasioseius latinoamericanus sp. nov., Proctolaelaps paulista sp. nov. and Protogamasellus sigillophorus sp. nov.. Among the other species collected, diagnoses and collection data are provided for Asca garmani Hurlbutt, 1963, Blattisocius tarsalis (Berlese, 1918), Proctolaelaps diffissus Karg, 1976 and Protogamasellus mica (Athias-Henriot, 1961 ); these are the first Brazilian collection records for these species other than B. tarsalis in stored products. Lasioseius helvetius Chant, 1958 is considered a senior synonym of L. saltatus Karg, 1980 (new synonymy), the latter reported previously from Brazil. Lasioseius quinisetosus Lindquist & Karg, 2006 (= Cheiroseius inguinalis Karg, 1977) is newly recorded from Brazil. Diagnoses and redescriptions are provided for L. helvetius and L. quinisetosus. Proctolaelaps intermedius Athias-Henriot, 1959 is considered a senior synonym of P. orientalis (Chant, 1963) and P. wenkochingi “(Samšinák, 1964)” (new synonymies).
A taxonomic revision of the genus Anoplocephaloides Baer, 1923 sensu Rausch (1976), with the description of four new genera (Cestoda: Anoplocephalidae)
Authors: HAUKISALMI VOITTO
Published: September 2022

The present study reviews the generic classification of all species assigned to Anoplocephaloides Baer, 1923 sensu Rausch (1976) (Cestoda: Anoplocephalidae) and related taxa, and proposes four new genera of anoplocephaline cestodes: Genovia n. g. for Anoplocephaloides wimerosa (Moniez, 1880), A. pseudowimerosa Tenora, Murai, Valero & Cutillas, 1982 and A. floresbarroetae Rausch, 1976, Sciurotaenia n. g. for Anoplocephaloides transversaria (Krabbe, 1879) and A. wigginsi (Rausch, 1954), Parasciurotaenia n. g. for Anoplocephaloides ryjikovi (Spasskii, 1950), and Equinia n. g. for Anoplocephaloides mamillana (Mehlis in Gurlt, 1831). The other new combinations are Microcephaloides neofibrinus (Rausch, 1952), Microcephaloides mascomai (Murai, Tenora & Rocamora, 1980) and Microcephaloides nevoi (Fair, Schmidt & Wertheim, 1990). In this revision, the emphasis is on morphological features that are shown to differ predictably between the monophyletic groups in the “arvicoline clade” of cestodes (i. e. among Anoplocephaloides s. str., Microcephaloides Haukisalmi, Hardman, Hardman, Rausch & Henttonen, 2008, Paranoplocephala Lühe, 1910 s. str. and Diandrya composita Darrah, 1930) and the phylogenetically related, basal Andrya rhopalocephala (Riehm, 1881), Neandrya cuniculi (Blanchard, 1891) and A. mamillana. These characters are the various external features, alternation of the genital pores, prominence of the genital atrium (=presence/absence of a genital papilla), and the structure and position of the uterus. Additional distinguishing features include the number and distribution of the testes (antiporal vs. poral+antiporal), length and shape of the cirrus sac, presence/absence of the retractor muscle of the cirrus sac, size and shape of the ovary and length of the vagina. In the key provided, the basal dichotomies are based on the alternation of the genital pores and the capability to form a genital papilla, which are easily observed in stained specimens.

Authors: RAMALHO L. V. , MURICY G. , TAYLOR P. D.
Published: September 2022

Research on cyclostome bryozoan taxonomy has been neglected compared to that on cheilostomes, especially in Brazil. Between 1890 and 1979, only 25 cyclostome species have been identified from Brazil, distributed among 11 genera and seven families. This study describes eight cyclostome species (Crisia pseudosolena, Nevianipora floridana, Mecynoecia cf. delicatula, Disporella pila, Patinella sp., Crisia fragosa sp. nov., Exidmonea zagorsek sp. nov., Supercytis savii sp. nov.), including a first record of the genus Supercytis in Brazilian waters.
Additions to the decapod crustacean fauna of the Hawaiian Islands, II. First record of the unusual hermit crab genera Porcellanopagurus Filhol, 1885, and Solitariopagurus Türkay, 1986 (Decapoda, Anomura, Paguridae)
Authors: MARTIN JOEL W. , MOFFITT ROBERT B. , MCLAUGHLIN PATSY A.
Published: September 2022

The rare and unusual deep water hermit crab genera Porcellanopagurus Filhol and Solitariopagurus Türkay are reported for the first time from Hawaiian waters. Each genus is represented by a single specimen collected from Penguin Banks, off the southwest coast of Moloka'i, Hawaii. The specimen of Porcellanopagurus is identified as P. platei, a species that has not been reported since its original description in 1902 based on specimens from the Juan Fernandez Islands off southern Chile. Therefore, the record is a major range extension for the species. The specimen of P. platei from Hawaii is an ovigerous female found inhabiting a fissurellid limpet shell; the species is redescribed based on type material. The specimen of Solitariopagurus, S. tuerkayi, was found carrying (inhabiting) one half of a bivalve mollusk shell (the lucinid Ctena bella), the first confirmation of this habitat for the species. A second specimen, photographed but now missing, was associated with a different species of bivalve (a mytilid). In addition to being new records of these genera for the Hawaiian Islands, the report also marks the first record of the genus Porcellanopagurus from the central Pacific and only the second record of the genus Solitariopagurus in the northern hemisphere.

The low biocompatibility of inorganic nanoparticles (NPs) is a main concern in their wide applications in the biomedical field. Therefore, the green synthesis of NPs from plant extracts can provide safe NPs for biomedical applications. The present study was aimed to assess the anticancer activity of bismuth oxide (Bi2O3) NPs fabricated using aqueous plant extracts from the rhizome ofCurcuma longa(C. longa). Characterization of green Bi2O3NPs was done using TEM, DLS, and X-ray diffraction analyses. Selective anticancer activity of green Bi2O3NPs against human glioblastoma (U87) cells was assessed using MTT, GSH, MDA, ROS, apoptosis, and caspase-3 assays. Also, qPCR analysis was done to explore the expression ofβ-catenin, cyclin D1, and c-myc at mRNA level as the important genes of the Wnt/β-catenin signaling pathway. The results showed that the green Bi2O3NPs have a crystalline nature with a size of around 30 nm with good colloidal stability attributed to potential bio-fabrication of Bi2O3NPs. Cellular study indicated that green Bi2O3NPs triggered selective anticancer activity against U87 cells through reduction of GSH level and increase of MDA level, ROS level, Annexin+cells, and caspase-3 activity. Also, it was found that IC50concentration of biosynthesized Bi2O3NPs (20μg/mL) resulted in a significant downregulation in the expression ofβ-catenin, cyclin D1, and c-myc genes involved in the Wnt/β-catenin signaling pathway. This study concludes that green Bi2O3NPs bio-fabricated from rhizome ofC. longashow potential selective anticancer activity.
