Authors: Ding Qi , Zhang Xiaoyu , Li Qi , Sha Huimin , Qiao Yunfa , Hu Zhenghua
Published: June 2022

Wine grape cannot grow well in cold areas. The cold resistance abilities of grape have become a very important problem to be solved. Effects of different fruit loads on the physiological and biochemical indexes of wine grape cultivar were studied through experiments. Results showed that different fruit loads had significant effects on the conductivity, soluble sugar content, Malondialdehyde (MDA), superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) of grape branches. Factor analysis and principal component analysis were used to analyze the physiological and biochemical indexes of cold resistance of wine grapes with different loads. Results showed that combined with the physical microstructure, physiological and biochemical data of branches, the best fruit load of wine grape was 5 kg in eastern foot of Helan Mountain, China.

Published: June 2022

Residual effects of organic manures on rice-blackgram cropping sequence, during 2017 and 2018 at Thoppur, Thirupparankundram, Madurai were studied at field levels. Twelve treatment combinations comprising various sources of nutrients (Green manure @ 6.25 t/ha, neem cake@250 kg/ha, Enriched FYM @1.0 t/ha, tamarind seed powder @ 100 kg/ha, vermicompost @ 4 t/ha, Panchagavya @ 3%, Multi varietal seed technique, herbal pest repellant spray @ 10%, state recommendation) in a Randomized Block Design with three replications laid out for rice, were used for rice fallow blackgram. The mean soil available N (345 kg/ha), phosphorous (33 kg ha-1) and potassium (310 kg/ha) of 2 cropping cycles were significantly superior with the application of green manure @ 6.25 t/ha along with split application of vermicompost in four equal splits @ 4 t/ha as basal, at active tillering, panicle initiation and flowering stages + Panchagavya @ 3 per cent as foliar spray twice at active tillering and panicle initiation stages. A similar trend was also observed with respect to soil chemical and biological properties viz., soil pH, organic carbon, fungi, bacteria and actinomycetes population in the same treatment. The results of present study confirm the benefits of organic sources of manures on the nutrient retention characteristic of soil and will be conducive to improve the soil fertility for achieving sustainable soil health.

Authors: Gaur Kompal , Jhanji Shalini , Dhatt KK
Published: June 2022

The uniform sized corms (3.5-4.0 cm dia) of Gladiolus grandiflorus L. were dipped in various concentrations of BA (50,75, 100 and 125 mg/l) and GA3 (50 , 75 , 100 and 125 mg/l) for 24 hrs. The Membrane stability index (MSI), Relative water content (RWC), total soluble sugars and total protein content of florets increased with the increased concentrations of BA and GA3. The post harvest quality parameters also improved with BA and GA3 treatments as compared to control but GA3 had more significant effect than BA. The treatment with 125 mg/l GA3 significantly hastened the opening of basal floret, increased the floret size, number of florets open at one time, per cent of opening of florets, water absorbed and led to maximum reduction in pH that ultimately led to improvement in vase life.

Published: June 2022

Morphological, phenological characterization and conservation management of Hedychium borneense R.M.Sm, a terrestrial-epiphytic herb and endemic to Kalimantan, Borneo are described. Results revealed that H. bornensee has a purple-brownish bractea, a terminal and raceme inflorescence, pale yellow flowers with a broad and pale-yellow labellum and orange stamen, a triocular fruit with an orange to red inner color, and brownish seeds with a dark red arillus. There are six phenology phases: initiation phase, flower development phase, pre-anthesis phase, anthesis phase, post-anthesis phase, and fruit development. Flower development lasts for 34 days, with a two-day anthesis phase in between. The ripe fruit occurs on day 94. It grows best in porous, moist environment; sphagnum moss and sand mix compost (1:1) is the best media for this plant. Since the plant is endemic, ex-situ conservation management through generative propagation is observed to be essential.

\(( \delta , \varepsilon)\)-orthogonality preserving mapping
between the continuous fields of Hilbert spaces on a locally

Authors: La Neve Angela , Falcicchio Giovanni
Published: June 2022

Epilepsy is a diffuse chronic neurological disease affecting around 50 million people worldwide. The diagnostic criteria by the International League against Epilepsy must be fulfilled to diagnose the disease, which is characterized by brief and transient episodes of abnormal neuronal activity involving one or both hemispheres, depending on the epilepsy type. The diagnosis of epilepsy should be properly and timely made because patients suffering from the disease are affected not only by seizure recurrence but also by epilepsy-related psychiatric and/or cognitive comorbidities that may have a huge impact with severe professional and social implications. It is of vital importance to define a specific governance model that has to be virtuously applied into the different phases of the clinical pathway of the patients with epilepsy in order to guarantee them the best model of care possible.

Terms Used for Smallpox and Its Personification in Korean Shamanic Language
Authors: Bruno Antonetta
Published: June 2022

The history of the terms and expressions associated with smallpox offers evidence of semantic change and reflects both the internal and external worldviews of Korean people with regard to smallpox. In Korean shamanic language, smallpox is personified as gods known by various names with their own linguistic registers, personalities, and behaviors. The present paper first analyzes the semantic relationship between the terms used for smallpox and for smallpox gods, and argues that similarities in their meanings and in the characteristics of the disease were determining factors in the creation of the gods’ personalities. The second part of the paper discusses how possession is defined in relation to the personification of smallpox, the smallpox goddess, and the person afflicted.
A Comparative Synthesis of American and Korean Parricidal Mass Murders
Authors: Shon Phillip
Published: June 2022

Contemporary studies of mass murder have examined attacks carried out by current or former students in educational settings or disgruntled employees at former places of work. Recently conceptualized as “active shooter events,” this type of public mass killing has eclipsed the most pervasive one throughout the twentieth century: mass killings within the family. The dearth of scholarly work on mass killings in the context of parricides in other national and cultural contexts is notable given the salience of family killings in the homicide literature. Using previously published findings on parricides in nineteenth-century America and
twentieth-century Korea, this paper provides a comparative synthesis of parricidal mass murders—mass killings that occur during the course of parricides. Notable points of convergence and divergence are discussed relative to culture and offense characteristics.

Berdasarkan data Kementrian Kesehatan Republik Indonesia tahun 2020, kasus DBD (Demam Berdarah Dengue) tersebar di 472 kabupaten dalam 34 provinsi, sebanyak 95.893 kasus dan 661 angka kematian akibat DBD. Kasus Demam berdarah ini kian meningkat setiap tahunnya. Menurut keterangan Organisasi Kesehatan Dunia (WHO), salah satu potensi DBD ditularkan ke manusia melalui gigitan Aedes aegypti betina yang terinfeksi. Gejala demam berdarah yang ringan dapat menyebabkan suhu badan tinggi, bintik merah pada kulit, rasa sakit pada otot serta sendi. Sementara itu demam berdarah dapat berakibat komplikasi yang dikenal dengan istilah dengue hemorrhagic fever, yang dapat menyebabkan Menorrhagia atau pendarahan yang berlebihan, serta Hipotensi atau penurunan tekanan darah secara ekstrem, bahkan menyebabkan kematian. Dengan urgensi terhadap DBD yang ditularkan oleh nyamuk ini, banyak masyarakat yang masih menggunkan cara manual untuk membasmi nyamuk, seperti menggunakan raket nyamuk ataupu kelambu. Cara itu dinilai kurang efektif dengan memakan banyak waktu dan tenaga serta hasil yang kurang maksimal. Oleh karena itu, dibutuhkan sebuah inovasi teknologi sebagai solusi alternatif dalam pemecahan masalah tersebut. Penelitian ini bertujuan untuk mengatasi permasalahan masyarakat dalam membasmi nyamuk secara manual. Dalam tulisan ini, penulis mengembangkan inovasi teknologi menggunakan ovitrap dengan metode image processing. Alat yang diciptakan nantinya dapat menarik perhatian nyamuk dengan lampu uv, setelah itu nyamuk akan mati karena tersedot kedalam ovitrap. Selain itu, alat ini juga dapat mengambil gambar nyamuk yang terperangkap dan melakukan perhitungan serta pengklasifikasian nyamuk, yang kemudian ditampilkan pada aplikasi berbasis dekstop. Alat ini diharapkan dapat membantu masyarakat maupun Juru Pemantau Jentik (Jumatik) untuk menciptakan lingkungan yang terhindar dari bahaya DBD.
CLIMATE CHANGE AND LIVELIHOODS: ADAPTATION PRACTICES BY RURAL TOURISM COMMUNITIES IN KARIMUNJAWA ISLAND
Authors: Setiawan Budi
Published: June 2022

The impacts of climate change have caused the changes in temperature, seasons, rainfall, sea level, storms, floods, drought, and extreme temperatures. Communities that are at the forefront to get the impacts of climate change are coastal and small island communities, one of which is tourism places. Karimunjawa is as one of areas that get the impact of the climate change. However, in a period of seven years, the development of tourism in Karimunjawa village has experienced a large increase as evidenced by the increasing number of foreign and domestic tourists. This paper aims to describe the phenomenon of adaptation and livelihood resilience in tourism-based villages on Karimunjawa Island as a socio-ecological system by applying the adaptive cycle as an exploratory diagnostic, dynamics, and direction tool of change in the socio-ecological system. This research utilizes a qualitative analysis of the livelihood adaptation strategies adopted by the informants. From the result of this study, it can be perceived that strategies to strengthen the resilience of communities, and especially the poor, must be based on a combination of the most effective measurable and increased commitment to the asset base and measures to provide better services. Therefore, local adaptation strategies are aimed at building livelihood resilience are very important because they will greatly affect the ability of communities to face the impacts of climate change. Tourism development policies in rural areas are very effective in building adaptation capacity and livelihood resilience of local communities. Local government institutions, particularly provincial governments, play an important role in fostering an enabling environment for local adaptation.
Patient's Adherence and Compliance and Quality of Life During/After VIT
Authors: Incorvaia Cristoforo , Heffler Enrico , Peveri Silvia , Pucciarini Francesco , Canonica Giorgio Walter , Ridolo Erminia
Published: June 2022

Adherence and compliance, respectively considered as a more positive, proactive behavior, resulting in a patient's lifestyle change to follow a daily regimen, and, as a more enforced response to an external command, are a critical aspect of any medical therapy, since it is estimated that less than half of the patients who are prescribed a therapy perform it, respecting the doses and duration. As far as aeroallergen immunotherapy is concerned, current data show that adherence is respected in about 50% of subcutaneous immunotherapy and in percentages even lower than 20% in sublingual immunotherapy treatments. This review analyzes the adherence to venom immunotherapy (VIT), in which, given its purpose of preventing potentially fatal anaphylactic reactions to insect stings, this aspect plays a critical role. In fact, protection from stings already takes place when the maintenance dose is reached, but VIT interruption before the recommended duration of 5 years exposes patients to new sting reactions. The data on adherence to VIT are far less abundant than that for aeroallergen immunotherapy. One of the first studies reported poor adherence in Austria, but the model used, consisting in the estimate of the percentage of patients with systemic reactions who accepted or rejected VIT, does not meet the criteria that define adherence to treatment. As for appropriate adherence studies, rates higher than 70% were reported in the United States and European countries. Studies from Italy found that good adherence were observed also in patients receiving, after 4 years of VIT, 3 months extended maintenance dose, as well as in patients treated during the COVID-19 pandemic, <10% of whom stopped VIT. Instead, only 35% of the patients treated for allergy to imported fire ant remained adherent after 1 year of treatment. However, also concerning honeybees and vespids, although adherence is satisfactory, it is possible to further improve it by increasing information and support for patients. Health-related quality of life (HRQL) is an efficient measure to estimate the effectiveness and safety of medical treatment. Tools designed to make patients aware of its improvement through VIT and, in particular, of the complete prevention of the risk of fatal reactions have an important role in reinforcing adherence. However, aspects not yet evaluated, such as the possible relationship between the efficacy of VIT and HRQL or its particular features in patients with mastocytosis, deserve specific studies.

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated gene (Cas) system and RNA interference (RNAi)-based non-transgenic approaches are powerful technologies capable of revolutionizing plant research and breeding. In recent years, the use of these modern technologies has been explored in various sectors of agriculture, introducing or improving important agronomic traits in plant crops, such as increased yield, nutritional quality, abiotic- and, mostly, biotic-stress resistance. However, the limitations of each technique, public perception, and regulatory aspects are hindering its wide adoption for the development of new crop varieties or products. In an attempt to reverse these mishaps, scientists have been researching alternatives to increase the specificity, uptake, and stability of the CRISPR and RNAi system components in the target organism, as well as to reduce the chance of toxicity in nontarget organisms to minimize environmental risk, health problems, and regulatory issues. In this review, we discuss several aspects related to risk assessment, toxicity, and advances in the use of CRISPR/Cas and topical RNAi-based technologies in crop management and breeding. The present study also highlights the advantages and possible drawbacks of each technology, provides a brief overview of how to circumvent the off-target occurrence, the strategies to increase on-target specificity, the harm/benefits of association with nanotechnology, the public perception of the available techniques, worldwide regulatory frameworks regarding topical RNAi and CRISPR technologies, and, lastly, presents successful case studies of biotechnological solutions derived from both technologies, raising potential challenges to reach the market and being social and environmentally safe.

Inducing lipid peroxidation and subsequent ferroptosis in cancer cells provides a potential approach for anticancer therapy. However, the clinical translation of such therapeutic agents is often hampered by ferroptosis resistance and acquired drug tolerance in host cells. Emerging nanoplatform-based cascade engineering and ferroptosis sensitization by p53 provides a viable rescue strategy. Herein, a metallo-organic supramolecular (Nano-PMI@CeO2) toward p53 restoration and subsequent synergistic ferroptosis is constructed, in which the radical generating module-CeO2 nanoparticles act as the core, and p53-activator peptide (PMI)-gold precursor polymer is in situ reduced and assembled on the CeO2 surface as the shell. As expected, Nano-PMI@CeO2 effectively reactivated the p53 signaling pathway in vitro and in vivo, thereby downregulating its downstream gene GPX4. As a result, Nano-PMI@CeO2 significantly inhibited tumor progression in the lung cancer allograft model through p53 restoration and sensitized ferroptosis, while maintaining favorable biosafety. Collectively, this work develops a tumor therapeutic with dual functions of inducing ferroptosis and activating p53, demonstrating a potentially viable therapeutic paradigm for sensitizing ferroptosis via p53 activation. It also suggests that metallo-organic supramolecule holds great promise in transforming nanomedicine and treating human diseases.

Katsuwonus pelamispeptide and its complexes have the effect of lowering uric acid (UA)-levels. To identify the effect and possible mechanisms, different concentrations ofKatsuwonus pelamispeptide and its complexes were administered to the zebrafish and mice hyperuricemia models, and the UA level was measured. Meanwhile, the hyperuricemic mice were treated orally at 0.83, 1.67, and 5.00 mg/g body weight for 7 days withKatsuwonus pelamispeptide and the complexes groups, separately. The levels of serum UA (SUA), urinary UA (UUA), serum creatinine (SCR), blood urine nitrogen (BUN), and xanthine oxidase (XOD) activities were detected in each group. The results showed that theKatsuwonus pelamispeptide (125 μg/ml) and its complexes (83.3 and 250 μg/ml) effectively reduced UA level in zebrafish with hyperuricemia (p< 0.05). TheKatsuwonus pelamispeptide at high concentration (5.00 mg/g) decreased the SUA level, SCR level, BUN level, and hepatic XOD activity, and the complexes (1.67 and 5.00 mg/g) significantly reduced the SUA level and hepatic XOD activity (p< 0.05) in the hyperuricemic mice. In addition, in a hyperuricemic mouse model, the UUA level was increased after treatment withKatsuwonus pelamispeptide and its complexes at high concentrations (p< 0.05). The total therapeutic effects in theKatsuwonus pelamispeptide complex group were better than those in theKatsuwonus pelamispeptide group. Thus,Katsuwonus pelamispeptide and its complexes may possibly be used to prevent hyperuricemiaviapromoting urate secretion and inhibiting XOD activity production.

α-Glucosidase is a potent drug target for treating type II diabetes mellitus. A great number of α-glucosidase inhibitors have been developed based on the molecular skeletons of bioactive natural products. However, efficient fluorescent probes for α-glucosidase detection are still limited, not to mention the probes with additional inhibitory functions. In this work, aiming for the enzyme’s highly specific detection, we designed and synthesized two environmentally sensitive fluorescent probes, namely, LD01 and LD02, respectively, based on conjugates of coumarin and cinnamic acid derivatives. We found a significant responsive emission enhancement upon LD02’s binding to α-glucosidase. These newly designed probes can act as a simple but efficient tool to evaluate the binding affinity of α-glucosidase to their inhibitors.

Published: June 2022

Vascular endothelial cells (ECs) play a pivotal role in whole body homeostasis. Recent advances have revealed enhancer-associated long non-coding RNAs (lncRNAs) as essential regulators in EC function. We investigated LINC00607, a super enhancer-derived lncRNA (SE-lncRNA) in human arteries with an emphasis on ECs. Based on public databases and our single cell RNA-sequencing (scRNA-seq) data from human arteries collected from healthy and diabetic donors, we found that LINC00607 is abundantly expressed in the arteries and its level is increased in diabetic humans. Using RNA-sequencing, we characterized the transcriptomes regulated by LINC00607 in ECs and vascular smooth muscle cells (VSMCs) and in basal and diabetic conditions in ECs. Furthermore, through transcriptomic and promoter analysis, we identified c-Myc as an upstream transcription factor of LINC00607. Finally, using scRNA-seq, we demonstrated that modified antisense oligonucleotide inhibitor of LINC00607 can reverse dysfunctional changes induced by high glucose and TNFα in ECs. Collectively, our study demonstrates a multi-pronged approach to characterize LINC00607 in vascular cells and its gene regulatory networks in ECs and VSMCs. Our findings provide new insights into the regulation and function of SE-derived lncRNAs in both vascular homeostasis and dysfunction in a cell-type and context-dependent manner, which could have a significant impact on our understanding of epigenetic regulation implicated in cardiovascular health and diseases like diabetes.

Published: June 2022

Aims

To perform a systematic review assessing the clinical manifestations and outcomes of cardiorenal syndrome or the presence of both cardiac and renal complications in the 2019 coronavirus disease (COVID-19) patients.

Methods

All relevant studies about cardiorenal syndrome or both cardiac and renal complications in COVID-19 patients were retrieved on PUBMED, MEDLINE, and EMBASE from December 1, 2019 to February 20, 2022.

Results

Our search identified 15 studies including 637 patients with a diagnosis of cardiorenal syndrome or evidence of both cardiac and renal complications followingSARS-CoV-2 infection. They were male predominant (66.2%, 422/637), with a mean age of 58 years old. Cardiac complications included myocardial injury (13 studies), heart failure (7 studies), arrhythmias (5 studies), or myocarditis and cardiomyopathy (2 studies). Renal complications manifested as acute kidney injury with or without oliguria. Patients with cardiorenal injury were often associated with significantly elevated levels of inflammatory markers (CRP, PCT, IL-6). Patients with a diagnosis of cardiorenal syndrome or evidence of both cardiac and renal complications had more severe disease and poorer prognosis (9 studies).

Conclusion

The presence of either cardiorenal syndrome or concurrent cardiac and renal complications had a significant impact on the severity of the disease and the mortality rate among patients with COVID-19 infection. Therefore, careful assessment and management of potential cardiac and renal complications in patients with COVID-19 infection are important to improve their outcomes.

Published: June 2022

Background

Hypoxemia is common in patients undergoing cardiac surgery, however, few studies about severe hypoxemia (SH) after cardiac surgery exist. The objectives of this study were to clarify the incidence, risk factors, and outcomes of SH after cardiac surgery.

Methods

Patients undergoing cardiac surgery from 2016 to 2019 in a single center were enrolled and were divided into two groups based on whether postoperative SH developed. Independent risk factors for SH were identified by univariate and multivariate analysis. Model selection statistics were applied to help determine the most parsimonious final model.

Results

Severe hypoxemia developed in 222 of the 5,323 included patients (4.2%), was associated with poorer clinical outcomes. Six independent risk factors for SH after cardiac surgery were identified by multivariate analysis, such as surgical types, white blood cell (WBC) count, body mass index (BMI), serum albumin, cardiopulmonary bypass (CPB) time, and intraoperative transfusion of red blood cells (RBCs). After comprehensively considering the discrimination, calibration, and simplicity, the most appropriate and parsimonious model was finally established using four predictors, such as WBC count, BMI, CPB time, and intraoperative transfusion of RBCs. A nomogram and a web-based risk calculator based on the final model were constructed to facilitate clinical practice. Patients were stratified into three risk groups based on the nomogram and clinical practice.

Conclusion

Severe hypoxemia was common after cardiac surgery and was associated with poorer clinical outcomes. A parsimonious final model with good discrimination, calibration, and clinical utility was constructed, which may be helpful for personalized risk assessment and targeted intervention.

Published: June 2022

It has been demonstrated that the tornado-scale vortex (TSV) is one of the fine-scale structures associated with extreme updrafts in the tropical cyclone boundary layer (TCBL), but the relationship between surface wind gusts and TSVs is still unclear. In this study, the one-second model output simulated in the Weather Research and Forecast (WRF) model with the large eddy simulation (WRF-LES) is used to investigate the relationships between TSVs and surface wind gusts. Results show that surface wind gust factors in the regions where TSVs are prevalent are significantly larger than those in other regions. 88% of the maximum gust factors associated with TSVs (vertical velocity larger than 20 m s−1) are larger than 1.25 (gust factors larger than 1.25 account for only 1% of the 1-min gust factors in the TC inner core), and the mean maximum 1-min gust factor associated with a TSV is larger than 1.3, while the mean 1-min gust factor in the TC inner core is only 1.1. The surface gust factors associated with TSVs in tropical cyclone eyewall can reach about 1.8, which can cause severe surface wind hazards. This study suggests that potential risk will increase in the regions where TSVs are prevalent because of the large wind gusts and gust factors. Finer real-time observations are needed to monitor the evolution of TSVs for improving the operational TC-related surface gust warnings.
