Authors: DİNÇ Fatma , YILDIZ Dilek
Published: December 2022

Adölesan dönem, bağımsızlıkların kazanıldığı, kimlik gelişiminin olduğu, aile, akran ilişkilerinde, okul ve mesleki başarıda dinamik değişikliklerin yaşandığı bir dönemdir. Sağlık hizmetindeki ilerlemeler, teknolojik gelişmeler, yenilikçi tedaviler ile çocukluk döneminde teşhis edilen hastalığa sahip çocukların yüzde doksanının olgunluk yaşına ulaşması beklenmektedir. Kronik hastalığı olan adölesanların ayrıca günlük tedavilerini bağımsız bir şekilde yönetmeleri istenmektedir. Fakat pediatrik ve yetişkin servisi arasındaki farklılıklar ile bakımın planlanması ile ilgili eksiklikler henüz yetişkin bakım sistemi için hazır olmayan adölesanların geçiş konusundaki direncini yükseltmektedir. Geçiş sonrasında hayal kırıklığı yaratabilmekte, erişkin doktorunu değiştirmesine neden olmakta, kontrollere düzenli gelmemelerine, ilaçlarına devam etmemelerine, acil servise sık başvurmalarına neden olabilmektedir. Bu nedenle kronik hastalığı olan adölesanların, pediatrik bakımdan yetişkin bakıma devri önemlidir. Sağlık ekibinin ayrılmaz bir parçası olarak hemşirelerin kronik hastalığı olan adölesanların sorunsuz bir geçiş sağlamada, kanıta dayalı geçiş planlamasına katılmada, başlatmada ve liderlik etmede önemli konumdadır. Ayrıca hemşirelerin sağlık bakım geçişinde adölesan ve genç yetişkinlerin geçişe hazır oluşunu değerlendirme, öz yönetim ve öz bakım becerileri konusunda eğitim verme, geçiş boyunca aileyi destekleme, ilaçların kullanımı konusunda eğitim verme, geçiş program bilgisini paylaşma, evde bakım ihtiyaçlarını değerlendirme rolleri vardır. Bu derlemenin amacı kronik hastalığı olan adölesanlarda sağlık bakım geçişinin önemi ve hemşirenin rolleri hakkında bilgi vermektir.

This study was conducted to examine Turkish nursing students’ perceptions and protective behaviors regarding premarital sexual intercourse and virginity by sex. The study had a cross-sectional descriptive design and was performed with 988 nursing students. Data were collected through face-to-face interviews. Although male students have more sexual experiences before marriage, they give importance to virginity to the person they will marry and approve the hymen examination. Boy students were found to prefer having anal or oral sex or rubbing or touching genitals so as not to harm the hymen compared to girl students. There were significant differences among university students by sex in terms of starting premarital sexual activity, having sexual experiences, perceptions about virginity, and resorting to protective approaches. There were significant differences among university students by sex in terms of starting premarital sexual activity, having sexual experiences, perceptions about virginity, and resorting to protective approaches. This shows that different responsibilities are imposed on the sexes about sexual experience culturally.

Published: December 2022

To determine the effectiveness of propofol alone (P), and the combination of xylazine-propofol (XP), xylazineketamine (XK), xylazine-thiopentone (XT), anaesthetic protocols were studied in randomly selected 16 healthy indigenous pigs of either sexes, age 12 to 15 months and weight ranging from 12 to 16 kg. The responses of propofol and the combinations in different stages of anaesthesia were closely monitored. Various reflex responses and muscle tenacity were also observed concurrently during the period of anaesthesia. The study found the shortest (0.29±0.02 min) induction period with XT anaesthesia and the longest (2.95±0.21 min) by XK; whereas, induction of anaesthesia with P and XP was 0.4±0.08 and 0.41±0.08 min respectively. The time required for maximum depth of anaesthesia was the shortest in P (7.50±0.65 min) than the combinations. However, the anaesthetic protocol with XP produced the highest (65.25±3.30 min) duration of anaesthesia than the shortest (10.75±1.75 min) extent with P. Moreover, time to recovery from anaesthesia was higher (83.25±2.14 min) in XT and shorter (18.50±1.32 min) in P protocol. Good muscle relaxation was observed in XP, XK and XT combinations. Palpebral, conjunctival, jaw, tail and digital reflexes were almost absent in XP and XT combinations. The study concluded that propofol itself is a safe anaesthetic for short surgical interventions and its combination with xylazine is to be recommended for prolonged surgical procedures in swine.

Bovine respiratory disease (BRD) is a condition of severe pneumonia caused due to environmental stress followed by a multiple viral and bacterial pathogens.The present study aimed to detect the BRD agents such as Mannhaeimia haemolytica, Pasteurella multocida and Histophilus somni and IBR in yaks suffering from respiratory infections. For the study, 157 deep nasal and blood samples were collected from yak of Arunachal Pradesh and processed for isolation and PCR detection of respiratory bacterial pathogens such as M. haemolytica, P. multocida and H. somni and seroscreening of IBR. From 157 samples, one M. haemolytica and two H. somni isolates were recovered. This is the first report of H. somni and M. haemolytica isolation from yak nasal samples from India. In mPCR, 23 yak nasal samples (14.6%) amplified for M. haemolytica, two (1.2%) for P. multocida and six samples for H. somni (4.6%) by simplex PCR. Concurrence of H. somni and M. haemolytica in three samples, and M. haemolytica and P. multocida type B in two samples was also observed.Very high seroprevalence for IBR (37%) by Indirect ABELISA was recorded.The study concluded that highest number of samples were positive for M. haemolytica (14.6%) and emphasizes its role in respiratory infections along with high seroprevalence of IBR. It also reflected the diagnostic importance of mPCR/PCR in regions inaccessible for fresh sample collection and transportation as an alternate to isolation procedures.

Published: December 2022

A comprehensive review on nutritive value of non-conventional meals and cakes, viz. sal seed meal, neem cake, castor oil cake, karanj cake, rubber seed meal, guar meal and palm kernel cake, their safe levels of inclusion in ruminant diet and various processing methods for their detoxification was carried out. CP content in above feeds was well above 20% except sal seed meal (14%). Among several methods water washing, soaking, steam cooking, chemical and biological methods were the most abundantly tried by the researchers. Chemical treatment was effective in reducing toxic principles from sal seed meal (80â€“90%), neem seed cake, castor oil cake (around 100%) and karanj cake. In several cases, water washing after chemical treatment resulted in huge loss of dry matter (DM). Biological treatment with fungal culture was successful for the safe inclusion of guar meal and rubber seed cake. Thus non-conventional ingredients on detoxification hold a great promise in reducing the competition for feedstuff among human and ruminants and also in balancing ruminant ration.

Published: December 2022

The present study was carried out to know the status of Beta Defensin-1 in goat semen before and after cryopreservation with beta defensin-1 supplemented semen diluent and in blood of different breeds of goat (Barbari, Jamunapari and Jakhrana). Goat semen (N-10) from each breed was collected by artificial vagina method. Immediately after collection, the volume, colour, consistency, and mass motility of ejaculate were assessed and were extended with Tris-Egg yolk-Fructose diluent having 10% (v/v) egg yolk and glycerol 6% (v/v). Samples were divided for estimation of beta defensinâ€“1 and rest parts were cryopreserved with semen diluent having beta defensin-1 @ 10 ng/mL. Blood samples (N-30) were also collected from the same animal after semen collection. The samples were stored at â€“20Â°C until assayed. Plasma membrane of sperm was broken by freeze thaw followed by ultracentrifugation (20,000 Ã— g for 5 min) at room temperature before ELISA test. The samples were diluted with Phosphate buffer (1:2) before analysis. The samples were analyzed using goat specific beta defensinâ€“1 commercial kit (EO6D0419) as per the manufacturerâ€™s instruction. The result showed that with supplementation of beta defensin-1 in goat semen, diluent maintains the concentration of beta defensin-1 even after cryopreservation. There was significant decrease (P<0.05) in beta defensin-1 concentration in sample which had no supplement in semen diluent after cryopreservation. The supplementation of beta defensin-1 in goat semen diluent improved the post-thaw immune modulatory properties of semen.

Published: December 2022

Present study was aimed to investigate microsatellites for their association with pre-housing body weights and age at sexual maturity of RIR chicken. Genomic DNA samples were isolated from 114 birds maintained at institute. PCR amplified products of selected microsatellite loci were separated on 3.4% MetaPhoreTM agarose gel and their sizes were determined by Quantity One software on GelDoc system. Locus specific alleles were identified according to their sizes, and their association with the quantitative traits was assessed by least squares analysis of variance. The analysis revealed significant association of microsatellite MCW0069 locus with chick weight, ADL0158 and MCW0258 loci with eighth week body weight (BW8), MCW0103 locus with BW16, ADL0158 locus with BW20, ADL0273 and MCW0103 loci with age at sexual maturity (ASM). The highest chick weight estimates were found in AB (183:174 bp) genotype of MCW0069 locus, whereas EE (189:189 bp) and BE (219:189 bp) genotypes of ADL0158, AB (280:273 bp) and CC (267:267 bp) genotypes of MCW0103, CD (107:102 bp) genotype of MCW0110, AE (216:147 bp) genotype of MCW0258 demonstrated the highest pre-housing body weight estimates. AB (160:147 bp) genotype of ADL0273 locus demonstrated the least age at sexual maturity (127.39Â±4.23 days) followed by its BB (147:147 bp) genotype. CC genotype of MCW0103 also had the least ASM (132.46Â±2.46 days) among its other genotypes and was better than BB genotype of ADL0273 locus. These findings suggest faster genetic progress in RIR chicken line by adapting microsatellite genotype based selection.

This study evidences that, stress due to vaccination can cause re-activation and clinical outbreak of bovine herpesvirus-1 in latently infected cattle. Three to four days following mass-vaccination of cattle against Foot and Mouth Disease in Karnataka of India, symptoms of acute respiratory distress, conjunctivitis and vulvo-vaginitis were observed in vaccinated cattle in many villages of the state. Nasal and ocular swabs were collected from 25 ailing cattle in six villages of Hassan district of Karnataka. Upon bacteriological analysis, the samples were found negative for Pasteurella multocida. The serum samples from ailing animals were positive for bovine herpesvirus- 1 (BoHV-1) antibodies by Indirect-ELISA. The swab samples were found for BoHV-1 by PCR targeting glycoprotein- C gene of BoHV-1. The swab samples when subjected to virus isolation in MDBK cells yielded characteristic CPE of bunch of grape like clustering of cells by fifth passage. PCR targeting conserved region on glycoprotein-C gene on DNA extracted from cell-culture supernatants showing CPE confirmed the presence of BoHV-1. Nucleotide sequencing of the PCR amplicon showed that the BoHV-1 isolated during this study shared 100% sequence identity with BoHV-1 isolates from India, Switzerland and Brazil. This study emphasizes that stress due to vaccination can cause re-activation and clinical outbreak of bovine herpesvirus-1 in latently infected cattle.

Authors: AL-MUTARY MOHSEN
Published: December 2022

The present investigation aimed to estimate the in vitro effects of resveratrol (RES) on the quality of chilled ram semen. Resveratrol was added to Triladyl® in three different concentration as 0 (control), 200 or 400 μM. Semen was collected from three Najdi rams, pooled and extended with one of three previous extenders for a final concentration of 600×106 sperm/ml. Then, the diluted semen was cooled gradually, and stored at 4°C. The total motility, viability, plasma membrane integrity and acrosome integrity were assessed at 0, 24, 72 and 120 h of storage. The thermal incubation test was evaluated at day 7. The survival time, total motility and the progressive motility were registered at day 15 of storage. After 4 h of incubation, the percentage of live sperm was significantly lower in the control group than in other groups. Results of survival time, total motility and progressive motility at day 15 of liquid storage were significantly higher in RES groups than that of the control. Based on the results of incubation resistance, survival time, total and progressive motility, it could be concluded that adding 200 and 400 μM of RES to Triladyl extender can improve the quality of ram semen during chilled storage at 4°C.

Now with advances in technology students and teachers alike can learn in the hands of technology. Currently, all countries in the world are facing the Covid-19 pandemic. All activities are restricted to prevent the spread of the Corona virus, including educational activities. In Indonesia, it has been more or less three months, all educational activities, from primary and secondary to tertiary levels, are conducted online. In this research concept, what researchers will do is how to make a website as a learning medium easily and can be understood by students and readers from all walks of life. Features can also be used properly so that students are interested and enthusiastic in independent learning. At the stage of making the website the researcher uses wordpress as a medium for editing the appearance of the theme or other features. So that it really can help researchers in simplifying and accelerating the creation of a website as a learning medium that helps students to learn independently online. At this stage the research model used is the waterfall model. Starting from the level and progress of the system, using this model has a systematic sequential software development method. In developing a website-based online learning mode as a means of increasing student independence in learning, teachers can update subject data, input new subject data, and delete unnecessary data. Subject data whose access time limit has been determined will be deleted by itself at a predetermined time. The teacher only needs to register as a teacher and can immediately become a teacher on the Website-Based Online Learning Mode Development Website as a Means to Increase Student Independence in Learning after passing certain predetermined phases and conditions. After completing teaching and learning activities, users can close the account or Logout from an existing account on the Website. After that, the website can be closed by closing the browser application which is used to open a website-based online learning mode development website as a means of increasing student independence in learning.

Published: December 2022

Background. The bijao (Calathea lutea) is a plant of great importance since it has been used for years in the wrapping of an emblematic Colombian confectionery that is a cultural and financial staple in the area where it is produced. Objective. The aim of the research was to identify socioeconomic characters of peasant families dedicated to the production and sale of bijao leaf were, identify the main plant species that accompany bijao in the ecosystem and document the community's perception of the ecosystem services associated with the plant's ecosystem. Methodology For the development of this study, were used community interviews, questionnaires, workshops and verification visits at farms and cover forest areas and crop field with Bijao.   Results. Predominantly, leaf production was conducted through family farming in transition, with women playing a fundamental role in the process. The community attributes an important ecological role to bijao, which is predicated on the protection and regulation of water, soil, climate and biodiversity. Implications. The study identified conservation values in an ecosystem where pressures exerted on the natural environment by agricultural production, urbanization and tourism prevail. Conclusions. The bijao leaf has socioeconomic importance and is part of the local tradition and culture of peasant families, the leaf is embedded in customs and gives identity to the territory. Women maintain the traditional knowledge of bijao for the next generations and it is an option of life and income for young people. The community recognized the environmental services and goods of the bijao areas on soil and water conservation. It provides conservation values of natural resources in an area with conflicts between forest conservation and where they produce agricultural goods.

Conclusion: A higher cytogenetic similarity of Penélope with Trinidad and Dulce has been revealed, suggesting that the latter may be the parents.
DIFFERENTIATION AND COMPLEXITY IN AGROECOSYSTEMS OF THE MEXICAN SUB-HUMID TROPICS
Authors: Casanova-Pérez Lorena , Martínez-Dávila Juan Pablo , Rosales-Martínez Verónica , Cruz-Bautista Patricia , García-Alonso Florencia
Published: December 2022

Background. In Mexico, the transition from a welfare state to a minimal state in the eighties generated a change in public policies that affected the poorest farmers in the country. Objective. This study analyzes the transformation of agroecosystem management practices in an area of the Mexican sub-humid tropics as a result of government abandonment of this productive sector. Methodology. This research is qualitative and requires techniques such as in-depth interviews and fieldwork. Thirty-seven (37) interviews were conducted with farmers over 60 years old. Participants were identified based on an intentional sample using the "snowball" technique. These findings are theoretically interpreted through Luhmann's complexity paradox. Results. The change in public policies, as well as the reduction in public spending assigned to the agricultural sector, led to changes in the management practices of agroecosystems, especially among producers with fewer resources that led to a process of differentiation between them and, at the same time, the existence of multiple interdependencies between them, as a way of dealing with the complexity derived from the conditions imposed by the predominance of a market economy, the abandonment of the government and, in recent years, the uncertainty in the behavior of the main agroclimatic variables. Implications. This work is qualitative and carried out in a local context but provides highlights on changes in areas relatively similar to the study area. Conclusion. The process of differentiation and interdependence among agroecosystems is based on the use of various technical-productive strategies, in addition to the use of collective work and social trust as social resources that help producers with fewer resources to deal with a complex problem.

Published: December 2022

Background. In Campeche, Mexico, livestock takes place in generally unfertilized grasslands and acahuales, where cattle rarely receive veterinary treatment. These characteristics suggest that some livestock producers could adopt organic production, but their availability for adoption is uncertain and there is little information to assess their feasibility. Objective. Evaluate the change capacity of the conventional livestock systems of Campeche with respect to the organic production model and specify the critical points in management that must be improved in the transition to organic farming. Methodology. Semi-structured interviews were conducted with 74 livestock producers belonging to the BioPaSOS-CATIE Campeche project, in locations in the municipalities of Escárcega, Champotón and Calakmul, as well as direct observations in cattle ranches. The information obtained was used in the Multi-criteria Organic Livestock Conversion Index (OLCI); built with 10 indicators and 35 variables. Results. OLCI showed a low level, but close to the intermediate level of organic standards. Indicators close to standards were: breeds and reproductive management, soil fertilization and feed management. Indicators that move away were: herd safety, ecological weed control in pastures and crops, pest and disease control in pastures and crops, veterinary prevention and treatment, animal welfare, sustainable pasture management and ecological management. Implications. The results obtained are useful for livestock producers in the state of Campeche, since strategies can be generated that allow the conversion of their production systems to an organic livestock model. They are also a benchmark for future research related to the subject of sustainability assessment or organic livestock using indicators. Conclusions. The evaluated livestock systems presented a low level of conversion to the organic production model. Critical points in management that hinder the transition to organic livestock are: sanitary hygiene control, application of synthetic herbicides and insecticides, breastfeeding up to eight months, appropriate stocking rate, use of a silvopastoral system and mainly advisory and training for organic certification, organic development plan and certification, internal control of the organic process and incentives for organic livestock production.

Privacy and mutual authentication under corruption with temporary state disclosure are two significant requirements for real-life applications of RFID schemes. This paper proposes two practical RFID schemes that meet these requirements. They differ from other similar schemes in that they provide reader-first authentication. Regarding privacy, our first scheme achieves destructive privacy, while the second one -- narrow destructive privacy in Vaudenay's model with temporary state disclosure. To achieve these privacy levels, we use Physically Unclonable Functions (PUFs) to assure that the internal secret of the tag remains hidden from an adversary with invasive capabilities. Both of our schemes avoid the use of random generators on tags. Detailed security and privacy proofs are provided.

Published: December 2022

Feature selection is vital in data pre-processing in machine learning, and it is prominent in datasets with many features. Feature selection analyses the relevant, irrelevant, and redundant features in the dataset. Feature selection removes the irrelevant features, which improves both the accuracy and prediction performance. The significant advantages of reducing the number of features from the dataset are reducing the training time, reducing overfitting, decreasing the curse of dimensionality, and simplifying the prediction model. The filter feature selection techniques can handle the issues with the high number of features, and this paper uses the symmetric uncertainty coefficient to verify the relevance of the independent features. In this paper, a new feature selection method named as kurtosis-based feature selection has been proposed to select the relevant features which affect the air pollution. Kurtosis-based feature selection is compared with seven filter feature selection techniques on air pollution dataset and validated the performance of the proposed algorithm. It has been observed that the kurtosis-based feature selection extracts only PM2.5 as the key feature and has been compared to the accuracy of the five existing methods. The experimental results illustrate that the kurtosis-based feature selection algorithm reduces the original feature set up to 91.66\%, but the existing filter feature selection techniques reduce the feature set to only 50\%.

In the modern world in various spheres of activity, the number of problems that need multi-criteria decision-making (MCDM) is constantly increasing. Researchers and experts offer a number of approaches to MCDM process in such tasks; in particular, most of them are based on expert methods. However, in practice, these methods require significant intellectual effort of experts and organizational and technical workload during the expert survey, and also usually take a long time. At the same time, it is not always possible for experts to use certain characteristics of alternatives, which also carries the risk of making decisions based on unfounded expert opinions. Therefore, such methods and tools should be clear and informative and at the same time easy to use to ensure the efficiency and effectiveness of their use. We offer a graph-based approach to expert decision-making and information visualization processes that meets these requirements and can significantly improve the efficiency of decision-making in multi-criteria selection tasks.

Gıda güvenliği, günümüzün milli güvenlik meseleleri arasında sayılmakta ve pek çok bilim dalı tarafından yeniden popüler bir çalışma alanı haline gelmektedir. Gıdanın ve beslenmenin insanlık tarihinin başından bu yana ana maddesi olarak kabul edilen tahıllar, ziraat ve ekonominin ihtisas alanı olarak değerlendirilmiştir. Ancak, tahıl meselesi, aynı zamanda devlet yönetimine içkindir ve bir kamu politikası alanı olarak tarihte yerini almıştır. Tahıl yönetimi, üretimden tüketime kadar geçen tüm süreçler için önerilen bir kavram olmakla birlikte olağanüstü koşullarda bu yönetim alanı daha net çizgilerle görülebilmektedir. Bunun Cumhuriyet tarihindeki en yakın örneği İkinci Dünya Savaşı sırasında Milli Korunma Kanunu ile deneyimlenmiştir. Bu çalışma, 21.yy’ın ilk çeyreği itibariyle tarihsel öneminden hiçbirşey yitirmeyen tahıl yönetiminin unsurlarını Milli Korunma Kanunu çerçevesinde ortaya koymaktadır. Yakın dönem tarihimizdeki bu deneyimi değerlendirmek, günümüzde Rusya ve Ukrayna arasındaki savaş nedeniyle tahıl üzerinde yoğunlaşan sıcak gelişmeler bakımından da önemlidir.

The present study was conducted to determine the effect of increasing temperature humidity index (THI) on lactating Murrah buffalo. The study was conducted on six lactating buffaloes which were offered the same basal diet and were blocked by days in milk, milk yield and parity. The study was conducted during May, June and July with average THI of 79.88, 80.57 and 85.36, respectively. Milk yield was recorded twice a day at 06:00 and 18:00 h and physiological parameters were recorded and blood was sampled on 30th day of each month at 14:30 h. The results showed a significant decrease (P<0.05) in milk yield in buffaloes only at a THI of 85.36 as compared to THI up to 80.57. The rectal temperature (RT) did not change (P=0.580) with increasing THI up to 85.36, however, the respiration rate (RR) and pulse rate (PR) changed (P<0.05) progressively with increasing THI. Leucocytopnoea, lymphocytopnoea and neutrophilia; and alteration in serum urea, alkaline phosphatase activity, reactive oxygen species and phosphorus concentration were observed only at a THI of 85.36 as compared to THI up to 80.57. Similarly, significant (P<0.05) alteration in serum T4, cortisol and prolactin levels were observed at a THI of 85.36 as compared to THI up to 80.57. It can be concluded that lactating buffaloes experienced mild heat stress up to a THI of 80.57 (May and June) and a moderate type of heat stress at a THI 85.36 (July).

La polinización artificial con ácido naftalenacético (ANA) ha aumentado el rendimiento de los cul- tivos en plantaciones sembradas con híbrido interespecífico E. oleifera x E. guineensis (OxG) porque disminuye la proporción de racimos mal conformados y aumenta el contenido de aceite en el mesocarpio. Esto ha favorecido la rápida adopción de la polinización artificial entre los cultivadores de palma de aceite, incluso cuando los detalles de su uso son actualmente objeto de investigación. En este contexto, hay estudios recientes que arrojan luz sobre la polinización artificial en palmas maduras, y se han reportado menos resultados para palmas de aceite jóvenes. Esta investigación se llevó a cabo para llenar este vacío de conocimiento. Se estimaron indicadores de eficiencia económica de la polinización artificial en cultivos con palma de aceite joven del cultivar híbrido Coari x La Mé en la plantación Palmeras de Puerto Wilches S. A. (PPW). El proceso de polinización se realiza aplicando polen de E. guineensis a las inflorescencias en antesis. Tanto 7 y 14 días después de la antesis (dda) se aplica ANA a las inflorescen- cias tratadas. Los resultados indican un costo por inflorescencia de $ 178 que incluye mano de obra, insumos, herramientas y supervisión de labor. Por otro lado, la conformación de racimos alcanzó un indicador superior a 90 %, frente a niveles anteriores de alrededor de 80 % con polinización realizada únicamente con polen E. guineensis en antesis. La supervisión de la mano de obra, los dispositivos digitales para capturar datos sobre el rendimiento de esta y el control adecuado de malezas contribuyeron al éxito del método modificado en PPW.

The U.S. Food and Drug Administration (FDA) approved 6 CAR T cell (CAR-T) products, including tisagenlecleucel (tisa-cel), axicabtagene ciloleucel (axi-cel), brexucabtagene autoleucel (brexu-cel), lisocabtagene maraleucel (liso-cel), idecabtagene vicleucel (ide-cel), and ciltacabtagene autoleucel (cilta-cel) in the last 5 years. CAR T-cell therapy significantly improved outcomes for patients with B-cell non-Hodgkin lymphoma (NHL) and multiple myeloma (MM). However, recurrence and progression may occur after the initial response due to multiple mechanisms (Zeng and Zhang, 2022) [1]. Furthermore, CAR T-cell therapy is not broadly utilized in solid tumors due to various barriers. This review discusses the evolution of CAR T-cell therapies and how the “younger-generation” CAR T cells counteract these challenges to potentially broaden their applications in the future.
Caribbean Metaverse Development: A Literature Review Perspective
Authors: RAMESHWAR Jason Robert , KING Graham S.
Published: December 2022

The Caribbean’s metaverse evolution accelerated due to the Covid-19 pandemic. This paper focuses on the metaverse, XR, and NFT and emphasises the Caribbean’s contribution to the virtual environment. A bibliometric analysis of metaverse-themed research identified the rapid increase in publications in 2021 and 2022 and that titles with XR (AR, VR or MR) occurred three times more than blockchain (including NFT). An evolving dataset was created based on a continuous scoping literature review of Industry 4.0 and its enabling technologies. This enables the creation of a new definition of the metaverse, understanding the UX benefits of XR and its applications' areas of foci, highlighting investment in XR-based projects, and illustrating the Caribbean-themed NFT and XR projects. This dataset revealed that UX benefits are linked to XR element features that are relevant, contextual, customised, hands-free and intuitive. It also revealed that XR applications have areas of foci that can enable machine control or data interface, designing and testing, remote support, education, customer engagement, remote collaboration or entertainment and escapism. Analysis of 54 XR papers revealed that the most popular area of focus was education (including training, learning and understanding). An evaluation of global investments in XR development showed funding ranged from USD 70K to USD 100M, and there needs to be focused financial support for Caribbean projects. This justifies continued research into factors influencing funding and encouraging Caribbean XR development. In addition, this research promotes regionally developed XR projects and NFTs. The paper's originality is the reductionist definition of the metaverse: a space designed for users by users, which can satisfy whomever, whatever, however, wherever and whenever. It manifests the user's extended reality, facilitated through XR technologies that enable Industry 4.0 (I4.0). As such, the metaverse can be considered the practical implementation of I4.0.

Published: December 2022

In this study, an in-depth literature review method was applied. Period; It examines academic studies and current information on the internet and its interpretation of entrepreneurship in the metaverse world. For those who want to be entrepreneurs in the world of Metaverse, business opportunities, conveniences and difficulties of Metaverse are evaluated. The concepts of virtual reality and virtual world, which are the leading steps of the rapidly developing digital age, are gaining importance. The metaverse world, which leads them and breaks new ground in the virtual world, is a universe in which it is predicted that investors will make large investments in terms of technology and economy. For this purpose, the researcher examined studies in the metaverse literature, and as a result of these studies, the subject of entrepreneurship in the metaverse world was discussed. In the metaverse world, the study results on entrepreneurship are seen as an opportunity to be seized economically. Those who will participate in the upcoming metaverse shift will seize this great opportunity. Another finding is that taking place in the metaverse world is not suitable for the time being in terms of costs. To avoid being affected by increasing costs, it is recommended that entrepreneurial individuals first determine a good idea and make a good feasibility study on how to realise this idea in the virtual world. This article is an original study that addresses the benefits, conveniences and challenges of being an entrepreneur in the Metaverse world. The literature review found no investigation on entrepreneurship in the Metaverse world. The fact that the Metaverse has the potential to have great effects on the business world and social life standards in the future makes this research more interesting. In addition, by specifying the impact of Metaverse on the business world, it has been tried to shed light on the problems and opportunities that large or small-scale enterprises and entrepreneurs will face in the future.

Published: December 2022

Biomonitoring offers an appealing tool for the assessment of pollution in aquatic ecosystem. Biological processes, species, or communities of bioindicators are used to assess the quality of the environment and how it changes over time. Bioindicators include algae, macrophytes, zooplanktons, insects, bivalves, molluscs, gastropods, fish, amphibians, and others. Changes in aquatic ecosystems are often attributed to anthropogenic disturbances, including pollution. Major contributors to aquatic pollution include wastewater, metals and metalloids, industrial effluents, contaminated sediments, nutrients, polycyclic aromatic hydrocarbons, flame retardants, persistent organic pollutants, pharmaceuticals and illicit drugs, emerging contaminants (such as microplastics and engineered nanoparticles), pesticides, herbicides, and endocrine disruptors. In this review, we discuss categories of aquatic pollutants, status and trends of aquatic biomonitoring and approaches, from genomics to populations. We conclude by offering recommendations for research and regulatory testing.
