Authors: Lima Teixeira Paulo de Tarso , Schäfer Gilmar , Martinello Back Marina , Belmonte Petry Henrique , Dutra de Souza Paulo Vitor
Published: October 2020

Rootstocks of ‘Rangpur’ Lime and ‘Swingle’ Citrumelo were grown in containers with substrate in a greenhouse, aiming to evaluate the effects of N (urea) fertilization on the vegetative growth and macronutrient content of the plant tissue. The experimental design was a factorial randomized block design with four repetitions, and each experimental plot was composed of five plants. Four doses of N (0, 2.0, 4.0 and 8.0 g.plant-1) were evaluated and applied every week (15 applications) to both of the rootstocks. After 200 days of transplanting, the following parameters were evaluated: vegetative growth and total content of macronutrients on the dry weight of the leaves, stems, and roots. ‘Rangpur’ Lime was more vigorous that ‘Swingle’ Citrumelo. ‘Rangpur’ Lime showed the greatest accumulation of plant dry weight with 3.38 g.plant-1 of N and a greater root dry weight with 2.03 g.plant-1. For ‘Swingle’ Citrumelo, 2.03 g.plant-1 of N provided a greater plant dry weight, however, nitrogen fertilization reduced the root:canopy ratio of the rootstocks. The leaf content of N and P were favored by high doses of N in the tested range. Intermediate doses favored the Ca and Mg leaf contents. The leaf K content was decreased by nitrogen fertilization.
David Albaharis Roman Der Bruder als Lektüre aus der sephardischen Diaspora
Authors: Deppner Corinna
Published: October 2020

In his novel The Brother, David Albahari designs a transmedial network that relates to the breakup of Yugoslavia and the breakup of a family. The confrontation with an unknown brother, who was adopted by a Jewish family in Argentinian exile, lets the coordinates of morality and aesthetics get out of hand: The brother not only reveals himself as a connoisseur of the literature of Jorge Luis Borges, he also bursts into the everyday life of a country that is unprepared for him as a transsexual person. In this spectrum of literary discourse and through the experience of homophobia, of diaspora and transgender reality, memories are stimulated by photographs and aesthetic lines of escape unfold and help accepting the unknown Other.

The results of the comparison of seasonal and daily variability of surface ozone (О3) and nitrogen dioxide (NO2) at urban monitoring stations in Moscow (Mosekomonitoring), Berlin, and Warsaw (European Environment Agency) for 2017-2018 are presented. Observational data indicate a leading role of vertical mixing in the atmospheric boundary layer in the formation of seasonal and daily regimes of surface ozone. Both seasonal and diurnal variations in О3 and NO2 are in good agreement at all stations. In the warm season, the anthropogenic factor becomes a key one for the formation of the daily maximum and increased levels of surface ozone under favorable meteorological conditions for active photochemical processes. The frequency of occurrence of high ozone values is determined, and an episode of atmospheric ozone values dangerous for public health is analyzed. Keywords: meteorological conditions, surface ozone, seasonal variation, diurnal variation, episodes of high ozone values Tab. 1. Fig. 3. Ref. 19.

Published: October 2020

Possible causes of extremely high waves in the Baltic Sea / Pohil A.E. // Hydrometeorological Research and Forecasting, 2020, no. 3 (377), pp. 58-70. The atmospheric conditions accompanying the occurrence of extremely high waves in the Baltic Sea (in particular, at the entrance to the Gulf of Bothnia) in 2004 and 2017 are analyzed. Changes in wave characteristics with a sharp decrease in the sea depth are considered. It is shown that the mechanisms like interference, when two wave systems overlap when rounding the island of Gotland, a superposition of a direct wave and a wave reflected from the steep slope at the entrance to the Gulf of Bothnia could contribute to the occurrence of extreme waves. Keywords: Baltic Sea, extreme waves, satellite data, water vapor fields Fig. 8. Ref. 19.

Published: October 2020

Overweight and obesity are major health concerns in Malaysia, which are linked to other health consequences such as type 2 diabetes mellitus, cardiovascular diseases and several others. Among dietary factors, sugar-sweetened beverages (SSBs) are reported to be one of the leading factors of weight gain and a higher body mass index (BMI). Sugar-sweetened beverages are beverages with added sugar that only add calories to an individual’s normal diet and they represent the largest contributor to the added sugars intake. This study was aimed to determine the prevalence of SSB consumption among university students in Kuala Nerus, Terengganu, as well as to investigate the association between the students’ SSB consumption and their BMI. A cross-sectional study was conducted among 350 Universiti Sultan Zainal Abidin (UniSZA) Gong Badak Campus and Universiti Malaysia Terengganu (UMT) students by using the convenience sampling. Each participant was given a questionnaire consisting of socio-demographic details, anthropometric assessment and beverage intake. The results revealed that half of the students consumed 2 cups (500 mL) of SSBs on average days (49.4%), whereas 21.7% of them consumed at least 3 cups daily. It was found that sweetened tea was the students’ most preferred SSB and there was also an association between the SSB consumption and the BMI. In conclusion, university students in Kuala Nerus drink 2 cups of SSBs daily and sweetened tea is their preferred SSB. Since the students’ SSB consumption influences their BMI, these students must be aware on the contents of SSB and the related health consequences in order to reduce the consumption of these beverages and hence, reduce their BMI to a healthy level.

Published: October 2020

The study evaluates the prevalence, knowledge, attitude, and practices of non-communicable diseases (NCDs) among adult Orang Asli and Malay ethnicity in Negeri Sembilan, Malaysia. This cross-sectional study involving 634 respondents aged 18 years and above of Orang Asli (51.3%) and Malays (48.7%) from the rural villages. Structured interview questionnaire for disease history and KAP level conducted. Weight, height, waist circumference, blood pressure, and blood glucose levels then measured. Prevalence of NCDs was higher among Malays compared to Orang Asli with hypertension (35.0% vs 14.8%), hypercholesterolemia (31.1% vs 5.2%), and diabetes mellitus (16.2% vs 4.3%), respectively. Malays also had a higher percentage of being abdominal obese (70.6% vs 59.7%) and increased blood pressure (54.4% vs 29.8%). Multivariate analysis indicates hypercholesterolemia [OR=6.035 (95%CI: 3.150,11.561)], abdominal obesity [aOR= 1.807 (95%CI: 1.065, 3.067)], and increased in blood pressure [aOR= 2.359 (95%C1: 1.619,3.437)] have a significant relation with Malay ethnicity. For Orang Asli, 51.7% had poor knowledge, 72.3% had a good attitude, and 16.0% had a good practice. Knowledge and attitude scores were significantly less among Orang Asli with no significant difference for practice compared to the Malays. The prevalence of NCDs among the Malays is alarmingly high, with an increasing trend among Orang Asli, which needs immediate attention. The NCDs and obesity were significant among Malays but also showed a worrying trend in the Orang Asli as the good practice on a healthy life-style was low in both ethnicities. Thus, proper education and promotion regarding NCDs needed for diseases screening and prevention.

Published: October 2020

Specific amounts of bacteria and fungi in the room can cause Sick Building Syndrome (SBS). The main reason for bacteria and fungi accumulation is a lack of air circulation in the air-conditioned room. Therefore, we study exhaust fan usage to microorganism concentration in the air-conditioned room. The objective of this study is to find the optimum exhaust fan running time for reducing microorganism concentration until below the threshold value. The quasi-experiment was using with repeated experiments and non-random methodology. The samples were consisting of four air-conditioned classrooms with six repeated measurements. The sampling instrument used a petri dish filled with NA (Nutrient Agar) and PDA (Potato Dextrose Agar) placed at five points in each room. The results showed that the variation of exhaust fan running time sig affected the concentration of bacteria (sig ~0) and fungi (sig 0.023) in the classrooms. We found that exhaust fan can reduce the bacteria concentration. Although we observed that the exhaust fan gives inconsistency effect to reduce the fungi concentration in the classrooms.

The implementation of the Chronic Disease Management Program or PROLANIS has been adopted in Indonesia by National Social Security Implementation on Health Agency (BPJS-K) since 2015. The program focuses on hypertension (HT) and diabetes mellitus (DM). However, since the first time the program was implemented, there was no comprehensive evaluation of it. The aim of this study was to analyze health service quality among HT and DM patients based on five dimensions of quality in 25 community health services (CHSs) in the Sleman district, Yogyakarta, Indonesia. This is a cross-sectional study with a simple random sampling technique that included 230 respondents from 25 CHSs. The instrument was SERVQUAL that consisted of 35 items of a questionnaire. The data were analyzed by a gap analysis, Customer Satisfaction Index (CSI) and Importance Performance Analysis (IPA); meanwhile, a Man–Whitney test was proposed to determine differences in health services quality in the PROLANIS program. Based on the gap analysis, it was found that whole dimensions were below 0-point; the CSI analysis obtained 74.45 for HT and 75.15 for DM; and the IPA analysis found that the distribution of respondents’ answers in the questionnaire were in quadrants 1 and 2. The Man–Whitney analysis was used to get the assurance aspect correlated with health service quality in DM and HT patients (p = 0.001). Health service quality in the PROLANIS program was based on five dimensions of quality was low, unless assurance dimension. The government should improve health services quality in aspects of tangibility, responsiveness, empathy, and reliability to get satisfaction among HT and DM patients in the PROLANIS program.

Dengue fever (DF) infection continues to present as a serious public health problem in Medan municipality, North Sumatera, Indonesia. The number of DF cases continuously increasing  recently. However, space time clusters of DF have not been investigated yet. A study was undertaken to detect clusters of DF incidence during 2015-2018 in Medan. Spatial geo-reference was conducted to 151 village coordinates by geocoding each village’s offices. A retrospective space-time scan statistic analysis based on population data and monthly DF incidence was  performed using SaTScan TM v9.4.4. Data of DF during 1 January 2015-31 December 2018 were analyzed using Poisson model to identify the villages at high risk of DF. The test of significance of the identified clusters of DF was based on comparing the likelihood ratio (LLR) against the null distribution obtained from Monte Carlo hypothesis testing. Total number of permutation was set to 999 and the significance level was set as 0.05. The highest LLR number was determined as the most likely cluster, while the rests were as the secondary clusters. This analysis identified 13 significant clusters. These DF clusters were initially spatially concentrated in the southwest and center of Medan and the last two years of study moved towards the northern part and identified in the last four months (September-December) of each year, which were the rainy seasons in the area. Most likely clusters were most frequently detected in the last three-year period of study in Anggrung village. Thirteen statistically significant DF clusters were identified in the 2015-2018 period. This may assist health authorities to improve the DF preventive strategies and develop public health interventions especially in the cluster’s area.

SOCIO-CULTURAL INFLUENCES ON CHILD LABOUR ISSUE IN ACEH PROVINCE INDONESIA
Authors: ROSANA YENNI , CHAUVEL RICHARD , FANG LAW SIEW
Published: October 2020

This research investigates the socio-cultural meaning of child labour in Aceh Province, Indonesia. Child labour is illegal in Aceh. However, there is no enforcement of laws and regulations to prevent child labour from occurring and this daily phenomenon is escalating at an alarming rate. Furthermore, this research presents some complexities and paradoxes. While, the general assumption is that poverty is the main cause of child labour; however, this study found that children who are less poor are also working. Most of these children maintain their schooling while working. Consequently, some communities reject the impact of child labour on formal education. Many communities also see work as part of education, which teaches children responsibility, independence and self-esteem and/or pride, which represents the strong qualities of traditional Acehnese people, which has shaped the patterns and behaviours of children working in the region. The community’s perspectives and other social polemics have continued the existence of child labour in Aceh. Therefore, Although it mights be not easy for the government to take actions, it is important to consider that the reduction of child labour programs in Aceh is not merely by strengthening the implementation of laws and regulations, but also requires the understanding of community values and attitudes around the issue.

We present a CO and atomic fine-structure line-luminosity function analysis using the ALMA Spectroscopic Survey (ASPECS) in the Hubble Ultra Deep Field. ASPECS consists of two spatially overlapping mosaics that cover the entire ALMA 3 mm and 1.2 mm bands. We combine the results of a line-candidate search of the 1.2 mm data cube with those previously obtained from the 3 mm cube. Our analysis shows that ∼80% of the line flux observed at 3 mm arises from CO(2–1) or CO(3–2) emitters at z = 1–3 (“cosmic noon”). At 1.2 mm, more than half of the line flux arises from intermediate-J CO transitions (J
up = 3–6); ∼12% from neutral carbon lines; and <1% from singly ionized carbon, [C ii]. This implies that future [C ii] intensity mapping surveys in the epoch of reionization will need to account for a highly significant CO foreground. The CO luminosity functions probed at 1.2 mm show a decrease in the number density at a given line luminosity (in units of L′) at increasing J
up and redshift. Comparisons between the CO luminosity functions for different CO transitions at a fixed redshift reveal subthermal conditions on average in galaxies up to z ∼ 4. In addition, the comparison of the CO luminosity functions for the same transition at different redshifts reveals that the evolution is not driven by excitation. The cosmic density of molecular gas in galaxies, ρ
H2, shows a redshift evolution with an increase from high redshift up to z ∼ 1.5 followed by a factor ∼6 drop down to the present day. This is in qualitative agreement with the evolution of the cosmic star formation rate density, suggesting that the molecular gas depletion time is approximately constant with redshift, after averaging over the star-forming galaxy population.
Constraints from Gravitational-wave Detections of Binary Black Hole Mergers on the 12C(α, γ)16O Rate

Published: October 2020

Gravitational-wave detections are starting to allow us to probe the physical processes in the evolution of very massive stars through the imprints they leave on their final remnants. Stellar evolution theory predicts the existence of a gap in the black hole mass distribution at high mass due to the effects of pair instability. Previously, we showed that the location of the gap is robust against model uncertainties, but it does depend sensitively on the uncertain

rate. This rate is of great astrophysical significance and governs the production of oxygen at the expense of carbon. We use the open-source MESA stellar evolution code to evolve massive helium stars to probe the location of the mass gap. We find that the maximum black hole mass below the gap varies between

and

, depending on the strength of the uncertain

reaction rate. With the first 10 gravitational-wave detections of black holes, we constrain the astrophysical S-factor for

at 68% confidence. With

detected binary black hole mergers, we expect to constrain the S-factor to within ±10–30

. We also highlight a role for independent constraints from electromagnetic transient surveys. The unambiguous detection of pulsational pair-instability supernovae would imply that

ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M
dust ∼ 40 M
⊕) ring-like disk with a dust cavity ∼50 au in radius and the secondary hosts a much lighter (M
dust ∼ 0.8 M
⊕) disk. As part of the high-resolution follow-up of the “Ophiuchus Disk Survey Employing ALMA” (ODISEA) project, we present 1.3 mm continuum and 12CO molecular line observations of the system at 002 (3 au) resolution. We resolve the disk around the primary into two nonaxisymmetric rings and find that the disk around the secondary is only ∼7 au across and also has a dust cavity (r ∼ 2.2 au). Based on the infrared flux ratio of the system and the M0 spectral type of the primary, we estimate the mass of the companion to be close to the brown-dwarf limit. Hence, we conclude that the ISO-Oph 2 system contains the largest and smallest cavities, the smallest measured disk size, and the resolved cavity around the lowest-mass object (M
⋆ ∼ 0.08 M
⊙) in Ophiuchus. From the 12CO data, we find a bridge of gas connecting both disks. While the morphology of the rings around the primary might be due to an unseen disturber within the cavity, we speculate that the bridge might indicate an alternative scenario in which the secondary has recently flown by the primary star causing the azimuthal asymmetries in its disk. The ISO-Oph 2 system is therefore a remarkable laboratory to study disk evolution, planet formation, and companion–disk interactions.
The eastern boundary of the geographic range of the Pallas’ spadefoot Pelobates vespertinus (Anura, Amphibia) is limited by overwintering temperatures

Published: October 2020

We studied the relationship between the geographic distribution of the Pallas’ spadefoot (Pelobates vespertinus) and the soil temperature regime at the eastern boundary of this species’ range (south-western West Siberia and northwest Kazakhstan). This species overwinters underground, burrowing down to 1.5 m or deeper and has poor frost tolerance – it is unable to withstand temperatures below 0 °C, therefore, the temperature at its overwintering depth has to be above zero. A cartographic approach to identifying the distribution of zero isotherms was used. Winter soil temperatures at depths of 80 cm, 120 cm, 160 cm and 240 cm were plotted, based on deep soil thermometer data and the outline of the spadefoot’s range was compared with close-to-zero isotherms in deep soil. Within the range of this species, the depth of the position of zero isotherms increases eastwards: from 80 cm in European Russia, to more than 160 cm in the south-west of Western Siberia. The eastern boundary of the species’ range lies in the forest-steppe, steppe and semi-desert zones in the Tobol-Ishim interfluve and further south, on the left bank area of the Turgai River. This boundary clearly coincides with the zero isotherm, which lies here at a depth of 160 cm, forming an impermeable barrier to the spadefoot’s distribution.

Authors: Harvey Arce Norman Patrick , Cuadros Valdivia Ana Maria
Published: October 2020

Due to globalization growth, learning a second language is a necessity to develop in an increasingly demanding multicultural environment. However, at present we still find that some traditional methodologies are still being applied for teaching, which represents a problem for current students, also called digital natives, because these methodologies should adapt to this digital age of technology and knowledge. To solve this problem, a digital resource for foreign language learning was developed taking into account competitiveness and gamification as bases to motivate students and engage them into the course. The objective of this tool is to improve the processing of theoretical information obtained making use of a virtual environment which has competitive activities and gamification elements such as: obtaining medals for completing tasks, user's progress bar and ranking according to the scores obtained, so that students are motivated and improve their learning. This research seeks to analyze the effects of applying competitiveness and gamification in a virtual environment aimed at foreign language learning. It was found that 81.03% of students are more inclined to use gamified digital tools and also 82.76% of students feel more motivated to learn a second language using this methodology.

Published: October 2020

This paper describes an experience to incorporate the realization of virtual routes about the sculptural heritage of a city in the classroom by developing a simulation of the urban environment using a video game engine. Video game engines not only allow the creation of video games but also the creation and navigation of in-teractive three-dimensional worlds. For this research, Roblox Studio has been used, a simple and intuitive program in which no previous programming skills are required. During the 2018/2019 academic year, a pilot experience was carried out with 53 secondary school students who were given the task of designing a virtual environment in which they had to include 3D models of the sculptural her-itage of the city of Santa Cruz de Tenerife. Before starting the experience, the par-ticipants answered a questionnaire to obtain a previous idea of the students' knowledge about the creation of video games. Once the activity was finished and in order to evaluate the result of the activity, the participants answered a final questionnaire. The students emphasized that after the activity they are more aware of the sculptural heritage of Santa Cruz and that they consider themselves capable of creating their own interactive worlds with Roblox.
Comprehensive Evaluation and Analysis of Teaching and Research Performance of Art Majors
Authors: Lyu Yin , Yang Xue , Yao Jiang
Published: October 2020

The growing popularity of art majors is overshadowed by the difficulty for art graduates to find a decent job. The teaching and research (T&R) performance of art majors should be evaluated comprehensively, such as to optimize resource allocation and improve teaching quality. Based on performance evaluation theory and input-output theory, this paper summarizes the features, problems and problem causes of performance evaluation for art majors. From the dimensions of teaching and research, a comprehensive index system was designed for T&R performance evaluation of art majors. On this basis, a performance evaluation model was constructed for art majors through principal component analysis (PCA). Finally, single-factor evaluation and comprehensive evaluation were conducted by our model on the T&R performance of the school of art design and school of industrial design in a university. The results show that: The performance evaluation of art majors is a small-scale yet complex and professional task, but the current evaluation methods lack sufficient attention, professionality, and targeted indices. The school of art design had a slightly higher ratio of excellent theses than the school of industrial design, reflecting the difference between the two schools in teaching results and quality. The school of industrial design invested much more than the school of art design. Both schools had improved the T&R outputs and comprehensive performance score since 2011, and the school of industrial design made the greater improvement in the comprehensive performance score.

Quadriplegia is a paralysis condition in both arms and legs so that the patient is only able to move his neck and head. Manual or electric wheelchairs with joystick or switch control as a tool for people with paralysis certainly cannot be controlled independently by quadriplegia sufferers. This study aimed to help quadriplegia sufferers not to depend on others in carrying out daily activities by developing electric wheelchairs that can be controlled independently. The bioelectric signal which has only been used for diagnostic purposes can be utilized as an electric wheelchair control system for quadriplegia sufferers. In this study, electric wheelchairs were controlled by electromyography (EMG) signals from muscle contractions that can be driven by quadriplegia sufferers, namely the neck and face muscles. The increase in EMG signal amplitude during the muscle contraction is used as a trigger for the electric motor in a wheelchair to move forward, backward, turn right, and turn left. An electronic circuit for signal conditioning was used to amplify the EMG signal leads and filter frequencies that are not needed by the system before being processed by the microcontroller circuit. The use of wireless systems was developed to reduce the use of cables connecting electrodes to patients with electronic devices that will provide comfort to the user. Based on the results of the data collection on the wheelchair system, the detectability and selectivity values were for the 100% and 94% forward commands, 94.33% and 100% reverse commands, 92.31%, and 96% right turn commands and 97.96% and 94.12% left turn commands. The electric wheelchair system with EMG signal control is expected to help the mobility of quadriplegia sufferers.

With the tremendous technological progress and the widespread use of a variety of technologies, we note how smart cities are providing services efficiently by using technologies. The aim of this project is to build a Smart Traffic Control System (STCS) to facilitate and optimize traffic flow, minimize traffic congestion, and reduce the waiting time by detecting the density on each street. This work has been carried on four phases. Firstly, collecting data by a questionnaire and we received 331 responses. Secondly, using Proteus simulation. Thirdly, building a low fidelity prototype, and fourthly: building the STCS model by using hardware (Arduino tools) and software (Arduino Software IDE). Finally, we learned how to build a system and we recommend using such a system in busy roads to reduced congestion and making traffic flow more efficient.

Published: October 2020

The purpose of this article is to investigate techniques for classifying tumor grade from magnetic resonance imaging (MRI). This requires early diagnosis of the brain tumor and its grade. Magnetic resonance imaging may show a clear tumor in the brain, but doctors need to measure the tumor in order to treat more or to advance treatment. For this purpose, digital imaging techniques along with machine learning can help to quickly identify tumors and also treatments and types of surgery. These combined techniques in understanding medical images for researchers are an important tool to increase the accuracy of diagnosis. In this paper, classification methods for MRI images of tumors of the human brain are performed to review the astrocytoma-containing glands. Methods used to classify brain tumors, including preprocessing, screening, tissue extraction, and statistical features of the tumor using two types of T1W and Flair brain MRI images and also the method of dimensionality reduction of extracted features and how to train them in classification are also explained. Determine the tumor area using three classification of Fuzzy Logic C-Means Clustering (FCM), Probabilistic Neural Networks (PNN) and Support Vector Machines (SVM). In this paper, simulated and real MRI images are used. The results obtained from the proposed methods in this paper are compared with the reference results and the results show that the proposed approach can increase the reliability of brain tumor diagnosis.
Biomedical Image Compression Techniques for Clinical Image Processing
Authors: Saudagar Abdul Khader Jilani
Published: October 2020

Image processing is widely used in the domain of biomedical engineering especially for compression of clinical images. Clinical diagnosis receives high importance which involves handling patient’s data more accurately and wisely when treating patients remotely. Many researchers proposed different methods for compression of medical images using Artificial Intelligence techniques. Developing efficient automated systems for compression of medical images in telemedicine is the focal point in this paper. Three major approaches were proposed here for medical image compression. They are image compression using neural network, fuzzy logic and neuro-fuzzy logic to preserve higher spectral representation to maintain finer edge information’s, and relational coding for inter band coefficients to achieve high compressions. The developed image coding model is evaluated over various quality factors. From the simulation results it is observed that the proposed image coding system can achieve efficient compression performance compared with existing block coding and JPEG coding approaches, even under resource constraint environments.
Macrophage-Associated Lipin-1 Promotes β-Oxidation in Response to Proresolving Stimuli

Macrophages reprogram their metabolism to promote appropriate responses. Proresolving macrophages primarily use fatty acid oxidation as an energy source. Metabolites generated during the catabolism of fatty acids aid in the resolution of inflammation and tissue repair, but the regulatory mechanisms that control lipid metabolism in macrophages are not fully elucidated. Lipin-1, a phosphatidic acid phosphatase that has transcriptional coregulator activity, regulates lipid metabolism in a variety of cells. In this current study, we show that lipin-1 is required for increased oxidative phosphorylation in IL-4 stimulated mouse (Mus musculus) macrophages. We also show that the transcriptional coregulatory function of lipin-1 is required for β-oxidation in response to palmitate (free fatty acid) and apoptotic cell (human) stimulation. Mouse bone marrow–derived macrophages lacking lipin-1 have a reduction in critical TCA cycle metabolites following IL-4 stimulation, suggesting a break in the TCA cycle that is supportive of lipid synthesis rather than lipid catabolism. Together, our data demonstrate that lipin-1 regulates cellular metabolism in macrophages in response to proresolving stimuli and highlights the importance of aligning macrophage metabolism with macrophage phenotype.

CD98, which is required for the rapid proliferation of both normal and cancer cells, and MET, the hepatocyte growth factor receptor, are potential targets for therapeutic antitumor Abs. In this study, we report that the antiproliferative activity of a prototype anti-CD98 Ab, UM7F8, is due to Ab-induced membrane-associated ring CH (MARCH) E3 ubiquitin ligase-mediated ubiquitination and downregulation of cell surface CD98. MARCH1-mediated ubiquitination of CD98 is required for UM7F8’s capacity to reduce CD98 surface expression and its capacity to inhibit the proliferation of murine T cells. Similarly, CD98 ubiquitination is required for UM7F8’s capacity to block the colony-forming ability of murine leukemia–initiating cells. To test the potential generality of the paradigm that MARCH E3 ligases can mediate the antiproliferative response to antitumor Abs, we examined the potential effects of MARCH proteins on responses to emibetuzumab, an anti-MET Ab currently in clinical trials for various cancers. We report that MET surface expression is reduced by MARCH1, 4, or 8-mediated ubiquitination and that emibetuzumab-induced MET ubiquitination contributes to its capacity to downregulate MET and inhibit human tumor cell proliferation. Thus, MARCH E3 ligases can act as cofactors for antitumor Abs that target cell surface proteins, suggesting that the MARCH protein repertoire of cells is a determinant of their response to such Abs.

It is with great sadness that we have learned about the passing of Professor David Yaffe (1929-2020, Israel). Yehi Zichro Baruch - May his memory be a blessing. David was a man of family, science and nature. A native of Israel, David grew up in the historic years that preceded the birth of the State of Israel. He was a member of the group that established Kibbutz Revivim in the Negev desert, and in 1948 participated in Israel’s War of Independence. David and Ruth eventually joined Kibbutz Givat Brenner by Rehovot, permitting David to be both a kibbutz member and a life-long researcher at the Weizmann Institute of Science, where David received his PhD in 1959. David returned to the Institute after his postdoc at Stanford. Here, after several years of researching a number of tissues as models for studying the process of differentiation, David entered the myogenesis field and stayed with it to his last day. With his dedication to the field of myogenesis and his commitment to furthering the understanding of the People and the Land of Israel throughout the international scientific community, David organized the first ever myogenesis meeting that took place in Shoresh, Israel in 1975. This was followed by the 1980 myogenesis meeting at the same place and many more outstanding meetings, all of which brought together myogenesis, nature and scenery. Herein, through the preparation and publication of this current manuscript, we are meeting once again at a “David Yaffe myogenesis meeting". Some of us have been members of the Yaffe lab, some of us have known David as his national and international colleagues in the myology field. One of our contributors has also known (and communicates here) about David Yaffe’s earlier years as a kibbutznick in the Negev. Our collective reflections are a tribute to Professor David Yaffe. We are fortunate that the European Journal of Translational Myology has provided us with tremendous input and a platform for holding this 2020 distance meeting "Farwell to Professor David Yaffe - A Pillar of the Myogenesis Field".
