DA’WAH TAJDID DAN MODERNISME; SEBUAH KAJIAN PERBANDINGAN
Authors: Alkhotob Imam Taufik Alkhotob
Published: May 2020

Tujuan Penelitian: Penelitian ini bertujuan untuk menggetahui perbandingan antaara da’wah tajdid dan da’wah modernisme. Metode Penelitian: Kuantitatif. Hasil Penelitian: Salah satu isu da’wah yang cukup dinamis dan menjadi diskusi hangat adalah tentang gerakan modernisme dalam dunia pemikiran Islam. Modernisme seringkali dipandang sebagai lawan dari tradisionalisme yang menganggap bahwa pemikiran lama tidak lagi dapat dipertahankan dan perlu diganti dengan yang baru. Hanya saja, persoalan yang muncul tidak sesederhana itu. Modernisme terbukti membawa paradigma baru dalam beragama yang justru hendak mendekonstruksi agama dan membongkarnya. Tidak hanya dalam agama Islam, tetapi juga terjadi pada agama lain. Disatu sisi modernisme juga seringkali disalah fahami semakna dengan istilah tajdīd. Padahal kedua istilah dan konsepnya memiliki perbedaan yang sangat dalam. Tajdid berorientasi positif dan berbasis pada syari’ah, sementara modernisme berbasis Barat dan berbahaya.
Is the Expansion of the Universe Accelerating? All Signs Still Point to Yes: A Local Dipole Anisotropy Cannot Explain Dark Energy
Authors: Rubin D. , Heitlauf J.
Published: May 2020

Type Ia supernovae (SNe Ia) provided the first strong evidence that the expansion of the universe is accelerating. With SN samples now more than ten times larger than those used for the original discovery, and joined by other cosmological probes, this discovery is on even firmer ground. Two recent, related, studies (N16 and C19) have claimed to undermine the statistical significance of the SN Ia constraints. Rubin & Hayden (RH16) showed N16 made an incorrect assumption about the distributions of SN Ia light-curve parameters, while C19 also fails to remove the impact of the motion of the solar system from the SN redshifts, interpreting the resulting errors as evidence of a dipole in the deceleration parameter. Building on RH16, we outline the errors C19 make in their treatment of the data and inference on cosmological parameters. Reproducing the C19 analysis with our proposed fixes, we find that the dipole parameters have little effect on the inferred cosmological parameters. We thus affirm the conclusion of RH16: the evidence for acceleration is secure.
Solar Flare Modified Complex Network

Published: May 2020

A constructive approach is developed to build the solar flare complex network by utilizing a visibility graph condition alongside the Abe–Suzuki method. Solar flare information such as position, start time, and peak flux is used for this purpose. The obtained characteristics of the topological features (such as the characteristic path length, power-law behavior of the probability distribution function of degrees, and the clustering coefficient) demonstrate the scale-free and small-world properties of the solar flare modified network. To explain the complexity of the constructed network, Omori’s law as well as the universal scaling features are investigated. Furthermore, a nonextensive modification of the Gutenberg–Richter law is examined for the solar flare modified network using a q-stretched exponential model. Establishing a two-dimensional map for the configuration of 118 energetic main flares observed between 2006 and 2016, it is found that the main flares are located within the regions consisting of hubs (high-connectivity regions) of the network. A fractal dimension of the solar flare network of about 0.79 is also obtained.
Successful treatment of extreme drug resistant Acinetobacter baumannii infection following a liver transplant
Authors: Aykota Muhammed Rasid , Sari Tugba , Yilmaz Sevda
Published: May 2020

Orthotopic liver transplantation is a life-saving procedure for patients with end-stage liver failure. However, Acinetobacter baumannii infections and acute rejection are important causes of morbidity and mortality following transplants. Here we present a case report of a cadaveric donor liver transplantation with infectious complications detected after transplantation.

The patient was a 64-year-old female. Because of non-alcoholic steatohepatitis due to hepatic insufficiency (model for end-stage liver disease (MELD): 12; Child-Pugh: 9B), liver transplantation from a cadaveric donor was performed. Following the transplantation, the patient developed a blood stream infection, urinary tract infection (UTI) and postoperative wound infection from biliary leakage. A. baumannii was isolated from blood, urine and wound cultures. Imipenem (4×500 mg), tigecycline (2×50 mg) and phosphomycin (4×4 g) were administered intravenously (IV). On the 14th day of treatment, the bile fistula closed and there was no bacterial growth in blood and urine cultures. The patient was discharged with full recovery.

The duration of a transplant patient’s hospital stay, intensive care unit stay, invasive interventions, blood transfusions and immunosuppressive treatments cause an increased risk of extensively drug-resistant (XDR) A. baumannii infections, and a high mortality rate is seen despite antibiotic treatment. Phosphomycin, used in combination therapy, may be an alternative in the treatment of XDR pathogens in organ transplant patients, due to its low side effect profile and lack of interaction with immunosuppressives.

Published: May 2020

Introduction: Considering that Group B Streptococcus (GBS) persists as an important cause of neonatal morbidity and mortality, the objective of this study was to evaluate the frequency of maternal colonization by GBS, comparing the culture by the Granada broth with the GeneXpert real-time PCR diagnostic methods and the impact of chemoprophylaxis in high-risk pregnant women.

Methodology: A prospective cohort of 110 pregnant women hospitalized for gestational complications was formed and recruited following interview and collection of rectovaginal swabs.

Results: The frequency of maternal colonization was 28.2% and statistically associated with Capurro> 37 weeks (p = 0.030) and neonatal infection (p = 0.008). Chemoprophylaxis was offered to 80% of those colonized. Among the pregnant women treated, a fivefold reduction in the rate of prematurity and rate of neonatal infection was observed. The sensitivity was 76.6% and 86.6% in culture and PCR, respectively, with an optimal index of agreement between the methods (K = 0.877). Grenade culture was considered an easy and low-cost method, while GeneXpert presented higher cost and error rate of 10%. However, 23.3% of the pregnant women were diagnosed exclusively by GeneXpert and the results were obtained in two hours.

Conclusions: This study showed a significant prevalence of maternal colonization for GBS and that both culture and molecular methods had peculiarities that allow different applicability, with the culture being feasible for antenatal screening and in the hospital for high-risk pregnant women with no sign of imminent delivery and GeneXpert being prioritized for situations of preterm birth.

Published: May 2020

Introduction: Human immunodeficiency virus (HIV) infection increases the susceptibility of patients for latent tuberculosis infection (LTBI) and reactivtion tuberculosis. This study aimed to compare the Quantiferon-TB gold-in tube test (QFT) with tuberculin skin test (TST) in the diagnosis of LTBI in HIV infected patients.

Methodology: This comparative study of 89 patients with HIV in the Behavioral Diseases Counseling Center in Hamadan was carried out from July 2015 to November 2016. After obtaining consent from the patients, all demographic data, clinical manifestations, and laboratory results (CD4 count, TST and QFT) were entered into the questionnaires. The CD4 count is usually routinely performed using flow cytometry at the Behavioral Counselling Center. Quantiferon-TB test was done by using Qiagen – Quantiferon-2 plate kit ELISA.

Results: Totally, 89 HIV infected patients with the mean age of 39.55 ± 10.31 years old were enrolled in the study. Sixty patients (67.42%) were male. The mean duration of HIV infection was 4.44 ± 3.88 years and the mean of CD4 count was 388.65 ± 260.66 cells/µL . Twenty patients had LTBI based on TST. Considering the QFT intermediate results as a positive test, the percent agreement of QFT and TST was 59.55%, which was not statistically significant (P = 0.2387).

Conclusions: According to the results, there was no significant percent agreement between QFT and TST for detecting LTBI in HIV infected patients. However, by decreasing CD4 counts, there was a significant relation between TST positive and LTBI in HIV patients.

Published: May 2020

Navicula incerta is a benthic diatom with potential use in nutrition and health for humans and aquaculture. Therefore, it is important to know its optimal growth conditions and biochemical composition. In this study, the effects of nitrate and silicate concentration on the growth kinetics and biochemical composition of N. incerta under laboratory conditions were measured. F/2 media was used as the control, and different concentrations of nitrogen (N/4, N/8 and N/16) and silicates (Si/4, Si/8 and Si/16) were evaluated. We measured cell concentration, chlorophyll-a and conducted proximal chemical analyses. It was found that different concentrations of nutrients affected the diatom’s growth kinetics and affected the concentrations of ash, chlorophyll, protein, lipids and carbohydrates. The highest concentration of lipids was obtained in the limiting treatment of nitrogen N/8 (27.09%), while the lowest value was found with silicate Si/8 media (16.97%). Carbohydrates increased compared to the control, with the N/16 treatment presenting the maximal concentration (23.31%). Treatments with reduced nitrate (N/8 and N/16) demonstrated the lowest concentrations of protein (18.75 and 12.44%, respectively), while in reduced silicate treatments, no statistical differences (P ≥ 0.05) were observed. Therefore, media limited nitrogen and silicates affected the growth kinetics and proximal chemical composition of N. incerta. The growth of this species using the N/8 medium is a suitable method for increasing lipid concentration in N. incerta.
An empirical relationship between sea surface temperature and massive stranding of the loggerhead turtle (Caretta caretta) in the Gulf of Ulloa, Mexico
Authors: Salinas-Zavala César A. , Morales-Zárate María V. , Martínez-Rincón Raúl O.
Published: May 2020

Two mass stranding events of loggerhead sea turtles (Caretta caretta) in the vicinity of the Gulf of Ulloa, Baja California Sur, Mexico, were analyzed during 2003-2006 and 2012-2014. Stranding events were related to the accumulation of consecutive days with lower sea surface temperature (SST) series for the corresponding periods using Pearson correlations. Our results showed that in both periods, a significant cross-correlation was observed between mass stranding and accumulation of consecutive days with temperatures below 18, 17, and 16°C, with a time lag of three to five months. Numerical evidence supports the hypothesis that although the loggerhead turtle mortality is caused by multiple factors under extreme cold events, the environment turns markedly unfavorable for these organisms. Side-effects on health and swimming behavior of the species C. caretta, compromise their ability to avoid obstacles or flee from predators, thus increasing their vulnerability to sickness or lethargy, and possibly leading to the massive stranding of weakened individuals or dead bodies to the beaches of the Gulf of Ulloa. Hence, while SST may not be the direct cause of turtle mortality, it can be a determining factor for the survival of this species.
Parental contribution in a cultivated stock for the spotted rose snapper Lutjanus guttatus (Steindachner, 1869) estimated by newly developed microsatellite markers
Authors: Perez-Enriquez Ricardo , Valadez-Rodríguez Janeth A. , Max-Aguilar Adriana , Dumas Silvie , Diaz-Viloria Noé
Published: May 2020

The spotted rose snapper Lutjanus guttatus is a fishery relevant species from the eastern Pacific Ocean, with aquaculture potential. Species-specific genetic markers are needed for the genetic characterization of wild and cultivated populations to help management strategies. Eighteen hypervariable microsatellites were developed by Next Generation Sequencing and characterized in a wild population sample. Genetic diversity was high (observed heterozygosity = 0.88 ± 0.050; the number of alleles per locus = 13.4 ± 1.3) and few loci departed from the Hardy-Weinberg Equilibrium, leaving 14 loci potentially suitable for population genetic studies. A reduced panel of five loci was tested in a cultivated stock to determine the parentage of progeny (embryonated eggs; n = 413), to estimate the temporal contribution of each parental broodstock. The above resulted in the successful assignment of 95.6% of the progeny to its parental couple, representing 17 out of the 24 possible families. Two of the four females produced most of those progeny (97.3%). These females, which reproduced throughout the season, did not spawn on consecutive days. The contribution of males was evenly distributed during the season and occurred on successive days. Some microsatellites can be used in other lutjanids (L. peru, L. argentiventris, and Hoplopagrus guentherii).

Published: May 2020

Non-compliance with fishing regulations is a widespread phenomenon in fisheries worldwide, jeopardizing the recovery of stocks and ecosystem services. There is an urgent need to fill the gaps in our understanding of the scale and nature of illegal fishing in artisanal fisheries, balancing the advances made in industrial fisheries. We explored patterns of fisher compliance with the existing minimum legal size (MLS) regulation in the small-scale benthic fisheries of central Chile. We focus on two of the most conspicuous species (loco Concholepas concholepas and keyhole limpets Fissurella spp.) and comparing two management regimes: management areas (MAs; local name for territorial use rights for fisheries) and open access areas (OAAs; no spatial entry restrictions). We also evaluated the effect of the spatial distribution of MAs, which determines the availability of OAAs on compliance. For both species, we measured the size of individuals in the catch in two consecutive years. We developed an index that accounts for the availability of open access areas per fisher. We found that a) the number of undersized individuals in the catch in OAAs is enormous, b) management regime influences both the median size and fraction of the undersized catch, and c) as the availability of OAAs per fisher decreases, illegal fishing increases, demonstrating the need to manage the levels of effort displacement in designing area-based instruments for management and conservation. Our findings also highlight the need to a) analyze the benefits of area-based instruments at the seascape scale, and b) develop and adapt instruments to prevent illegal fishing.

Published: May 2020

BACKGROUND: Recurrent respiratory tract infections (RRI) are one of the extremely high common reasons for pediatric visits and hospitalization. Immunodeficiencies are considered as important conditions that may increase the probability of occurrence of RRI. Mannose-binding lectin (MBL2) is a protein of the innate immune system involved in the opsonization and the complement activation. MBL2 deficiency is associated with infectious diseases mainly chest infections; however, subnormal MBL2 levels are also seen in healthy subjects. Primary immunedeficiencies are associated with recurrent infections which mainly appear in early childhood.
AIM: The aim of the study was to estimate T and B and natural killer cells percentage and to investigate the MBL2 and immunoglobulins (Igs) serum levels in children with recurrent RRIs in different genetic disorders compared to normal control.
METHODS: This study included 50 children having a history of recurrent RRIs. All patients had genetic disorders and referred to National Research Centre for follow-up, in addition to, 25 children, age- and sex-matched as a healthy control group. They were subjected to full clinical examination and laboratory investigations including complete blood count (CBC), CD3, CD4, CD8, CD16, and CD19 by flow cytometry, MBL2 by enzyme-linked immunosorbent assay (ELISA), and Igs serum concentrations by nephelometry.
RESULTS: CD16 showed a non-statistical significant difference between both patient groups. Serum levels of IgA in patient groups showed a significant decrease compared to the control group. Moreover, the serum level of IgM results shows a highly significant decrease when compared with the control group. There was no statistically significant difference in MBL2 and IgG serum levels between patient groups and control group.
CONCLUSION: Children with genetic disorders and recurrent RRIs showed a statistically significant decrease of IgA and IgM serum levels as compared to the control group, while the serum level of MBL2 did not show significant results.

Published: May 2020

CONTEXT: Plasma brain natriuretic peptide (BNP) levels are elevated in patients with acute ischemic stroke, particularly when accompanied by atrial fibrillation (AF). Plasma BNP might be a useful marker of vulnerability to thromboembolism in non-valvular AF patients.
AIM: The aim of the present study was to assess whether the BNP level can serve as a biomarker of the left atrial (LA) thrombus in AF patients with acute ischemic stroke.
SETTINGS AND DESIGN: This was a multicenter prospective cohort study.
PATIENTS AND METHODS: Thirty AF patients with acute ischemic stroke were included in the study. Their transesophageal echocardiography (TEE) and BNP were assessed.
RESULTS: There was a positive significant relation between serum BNP levels and LA thrombus detection by TEE. BNP with a cutoff value >498 pg/l can be used as a diagnostic biomarker for the presence of the LA thrombus. A significant positive correlation existed between serum BNP and LA diameter. Furthermore, a statistically significant positive correlation between serum BNP and AF rate and duration was found in all patients. In addition, a statistically significant inverse correlation was detected between serum BNP and direct bilirubin, international normalized ratio, and albumin. A statistically significant positive correlation existed between serum BNP and prothrombin concentration.
CONCLUSION: BNP can be a good diagnostic biomarker for the detection of the LA thrombus in chronic AF patients with acute ischemic stroke.

This paper studies a reaction-diffusion-advection system describing a directed movement of immune cells toward chemokines during the immune process. We investigate the global solvability of the model based on the bootstrap argument for minimal chemotaxis models. We also examine the stability of nonconstant steady states and the existence of periodic orbits from theoretical aspects of bifurcation analysis. Through numerical simulations, we observe the occurrence of steady or time-periodic pattern formations.

In the field of remote sensing image processing, the classification of hyperspectral image (HSI) is a hot topic. There are two main problems lead to the classification accuracy unsatisfactory. One problem is that the recent research on HSI classification is based on spectral features, the relationship between different pixels has been ignored; the other is that the HSI data does not contain or only contain a small amount of labeled data, so it is impossible to build a well classification model. To solve these problems, a dual-channel CNN model has been proposed to boost its discriminative capability for HSI classification. The proposed dual-channel CNN model has several distinct advantages. Firstly, the model consists of spectral feature extraction channel and spatial feature extraction channel; the 1-D CNN and 3-D CNN are used to extract the spectral and spatial features, respectively. Secondly, the dual-channel CNN have been used for fusing the spatial-spectral features, the fusion feature is input into the classifier, which effectively improves the classification accuracy. Finally, due to considering the spatial and spectral features, the model can effectively solve the problem of lack of training samples. The experiments on benchmark data sets have demonstrated that the proposed dual-channel CNN model considerably outperforms other state-of-the-art method.

Los autores de este trabajo -utilizando como referencia teórica el modelo tipológico de hermandades propuesto por l. Moreno para el área andaluza- abordan la plausible validación de dicho modelo en una población rural de la Comunidad Autónoma de Madrid, mostrando el aparato formal y la expresión ritual de las diferentes hermandades en estudio. Los mecanismos de integración, así como la articulación de una estructura social segmentaria, quedan plasmados a través de un pormenorizado análisis de los niveles diferenciales de identificación social con la comunidad. Más claramente: si las hermandades grupales operan como aglutinantes sectoriales de la comunidad -con sus particulares mecanismos de identidad-, la hermandad patronal diluye las identidades y pertenencias a grupos sociales en la reafirmación de la identidad ·colectiva, a través del culto a la Virgen de la Soledad.

Published: May 2020

Just like any other area in the world, which is quickly changing and converting in line with the scientific and technological developments, the models, approaches, and paradigms set forth as elements of learning and teaching have also undergone alterations and transformations from past to present. While the learning-teaching theories and approaches in the last century, which are based on perennialist and essentialist education philosophies and positivism paradigm, were deeming the learners as passive receivers of external stimuli and focused on the observable and measurable behaviors, the learning-teaching theories and approaches in our century, which are developed around the progressivism and re-constructionism philosophies and post-positivism paradigm, have an understanding that allocates the responsibility to the learner and adopts a lifelong learning by doing and experiencing. In this chapter, a general outlook on the learning and teaching theories and approaches will be briefly carried out.

The Digital Value Propositions for Virtual Business Incubators
Authors: Saavedra Angelo , Kotey Bernice , Sandhu Kamaljeet
Published: May 2020

Business incubators (BIs) are property-based initiatives that provide nascent entrepreneurs access to a mix of business support services and networking opportunities. These services are expected to foster the idea generation process from inception to commercialisation, with the hope they will later develop into self-sustaining, thriving ventures. Digital technologies have enabled BIs to extend their support services to include new digital services, and to expand their geographical coverage, giving rise to the virtual business incubator (VBI). This chapter provides a detailed review of the BI from its origin until the emergence of the VBI, highlighting their main characteristics, differences, and benefits. Furthermore, the author argues the view of the VBI as an extension of the BI is insufficient to fully understand its operations, value-added incubation services, and contribution to venture success. Therefore, a novel conceptual framework to define the VBI is proposed.
A Systematic Study for Digital Innovation in Management Education

Published: May 2020

The past two decades have witnessed an unrelenting expansion of management education around the world. At the same time, however, influential scholars—Mintzberg, Bennis, Pfeffer, and others—have leveled pointed critiques at these programs questioning their quality and relevance, as well as their approach to teaching and learning. In the present era of globalization, information technology is really an opportunity for the management education system in Vietnam to convert it to be globally competitive through world-class quality. The present management education model in Vietnam drags the features of the British model designed by the British to train the natives as “OGA,” enabling them to run the administration of the country at that time. Now the management or business education system has changed. Many modern business schools introduced several features in the management education system as replacing the traditional model of curriculum-teacher-student by problem-coach-problem solver, moral education, competence-based techniques approach, etc. This chapter explores and integrated approach to problem-based learning in Vietnam.

The gamification term, derived from the game concept, is the use of game-design elements (e.g., points, badges, levels, and leaderboards) in non-game contexts, often with the purpose of motivating and directing individuals' certain behaviors to achieve specific goals and outcomes. The contexts in which gamification is being researched and implemented include education, health, marketing, human resources, social networks, digital platforms, etc. Many studies conducted in various domains tried to understand and explain how gamification can influence or foster individuals' motivation to conduct goal-directed behavior digitally. In most of these conducted studies, significant impact of gamification on human behavior has been observed and proved. By presenting academic findings from literature and discussing real-world implementation examples from the relevant domain, this study assesses the role of digital gamification in e-commerce domain. This chapter shows how various digital game design elements can influence consumer behavior in different e-commerce platforms.

When the term lifelong learning (LLL) is the matter of discussion, its features, benefits, and limitations are also to be derived. In the era of digitization, digital learning is a buzz word for educating people irrespective of age. The concepts of digital learning must be clearly understood before embedding LLL in a digital environment. The contribution of web technology for the fusion of digital learning with LLL cannot be overlooked. To look deeper into it, a methodology is to be derived for LLL to best focus on the features. A framework for knowledge management (KM) has been proposed to create virtual learning communities (VLCs), which in turn will foster collaborative learning. Also, it is to be observed that by inducting the principles and practice of LLL in the digital environment, a blooming educational concept has erupted for the creation of knowledge society (KS). The chapter gives a clear discussion of LLL embedded in a digital learning environment.

Traffic optimization at an intersection, using real-time traffic information, presents an important focus of research into intelligent transportation systems. Several studies have proposed adaptive traffic lights control, which concentrates on determining green light length and sequence of the phases for each cycle in accordance with the real-time traffic detected. In order to minimize the waiting time at the intersection, the authors propose an intelligent traffic light using the information collected by a wireless sensors network installed in the road. The proposed algorithm is essentially based on two parameters: the waiting time in each lane and the length of its queue. The simulations show that the algorithm applied at a network of intersections improves significantly the average waiting time, queue length, fuel consumption, and CO2 emissions.

The IEEE802.11n wireless local-area network (WLAN) has been widely adopted due to the flexible coverage and lower installation cost. However, the TCP throughput unfairness was detected when multiple hosts concurrently communicate with a single access-point (AP). Previously, the authors proposed the TCP fairness control method for only two hosts in the elastic WLAN system using Raspberry Pi AP, which dynamically adapts the topology according to the traffic demand. The delay is introduced in the packet transmission to the faster host from the AP, which is optimized by the PI feedback control such that the measured throughput becomes equal between the hosts. In this paper, the authors proposed a generalization of this method for any number of hosts by newly introducing the target throughput as the equal goal among the hosts. It is dynamically updated using the measured throughputs. The effectiveness of the proposal is verified through experiments using the elastic WLAN system testbed with one AP and up to four hosts.

The diversity of Ig and TCR repertoires is a focal point of immunological studies. Rhesus macaques (Macaca mulatta) are key for modeling human immune responses, placing critical importance on the accurate annotation and quantification of their Ig and TCR repertoires. However, because of incomplete reference resources, the coverage and accuracy of the traditional targeted amplification strategies for profiling rhesus Ig and TCR repertoires are largely unknown. In this study, using long read sequencing, we sequenced four Indian-origin rhesus macaque tissues and obtained high-quality, full-length sequences for over 6000 unique Ig and TCR transcripts, without the need for sequence assembly. We constructed, to our knowledge, the first complete reference set for the constant regions of all known isotypes and chain types of rhesus Ig and TCR repertoires. We show that sequence diversity exists across the entire variable regions of rhesus Ig and TCR transcripts. Consequently, existing strategies using targeted amplification of rearranged variable regions comprised of V(D)J gene segments miss a significant fraction (27–53% and 42–49%) of rhesus Ig/TCR diversity. To overcome these limitations, we designed new rhesus-specific assays that remove the need for primers conventionally targeting variable regions and allow single cell level Ig and TCR repertoire analysis. Our improved approach will enable future studies to fully capture rhesus Ig and TCR repertoire diversity and is applicable for improving annotations in any model organism.
Rapid Death of Follicular B Cells and Burkitt Lymphoma Cells Effectuated by Xbp1s
Authors: Chen Yi-Ting , Kung John T.
Published: May 2020

BCR-mediated tonic signaling is an indispensable requirement for the survival of follicular B (FOB) cells and Burkitt lymphoma (BL) cells. FOB cells of the I-A12% mutant mouse express unfolded protein response and are extremely short lived. Among the myriad molecules activated by unfolded protein response in I-A12% B cells, Xbp1s singularly “hijacked” p110 from p85:p110 heterodimeric PI3K, thereby abating BCR tonic signaling, resulting in their extremely short lifespan. Long-lived normal FOB cells became short lived upon ectopic Xbp1s expression. The proapoptotic Xbp1s role in FOB cells starkly contrasts with its antithetical prosurvival function in plasma cells. Also, tonic signaling and clonal expansion, two important functions mediated by the same BCR, operate in independent and distinct manners. Furthermore, concerning the development of new therapeutic treatment of drug-refractory BL patients, our finding of Xbp1s-mediated rapid death of BL cells brings forth a conceptual advancement based on blocking PI3K heterodimer formation rather than inhibition of PI3K enzyme activity.

IL-2 is a pleotropic cytokine with potent pro- and anti-inflammatory effects. These divergent impacts can be directed in vivo by forming complexes of IL-2 and anti–IL-2 mAbs (IL-2C) to target IL-2 to distinct subsets of cells based on their expression of subunits of the IL-2R. In this study, we show that treatment of mice with a prototypical anti-inflammatory IL-2C, JES6-1–IL-2C, best known to induce CD25+ regulatory CD4 T cell expansion, surprisingly causes robust induction of a suite of inflammatory factors. However, treating mice infected with influenza A virus with this IL-2C reduces lung immunopathology. We compare the spectrum of inflammatory proteins upregulated by pro- and anti-inflammatory IL-2C treatment and uncover a pattern of expression that reveals potentially beneficial versus detrimental aspects of the influenza-associated cytokine storm. Moreover, we show that anti-inflammatory IL-2C can deliver survival signals to CD4 T cells responding to influenza A virus that improve their memory fitness, indicating a novel application of IL-2 to boost pathogen-specific T cell memory while simultaneously reducing immunopathology.
