Protein arginine methyltransferase 5 (PRMT5) participates in the symmetric dimethylation of arginine residues of proteins and contributes to a wide range of biological processes. However, how PRMT5 affects the transcriptional and epigenetic programs involved in the establishment and maintenance of T cell subset differentiation and roles in antitumor immunity is still incompletely understood. In this study, using single-cell RNA and chromatin immunoprecipitation sequencing, we found that mouse T cell–specific deletion of PRMT5 had greater effects on CD8+ than CD4+ T cell development, enforcing CD8+ T cell differentiation into Klrg1+ terminal effector cells. Mechanistically, T cell deficiency of PRMT5 activated Prdm1 by decreasing H4R3me2s and H3R8me2s deposition on its loci, which promoted the differentiation of Klrg1+CD8+ T cells. Furthermore, effector CD8+ T cells that transited to memory precursor cells were decreased in PRMT5-deficient T cells, thus causing dramatic CD8+ T cell death. In addition, in a mouse lung cancer cell line–transplanted tumor mouse model, the percentage of CD8+ T cells from T cell–specific deletion of PRMT5 mice was dramatically lost, but CD8+Foxp3+ and CD8+PDL1+ regulatory T cells were increased compared with the control group, thus accelerating tumor progression. We further verified these results in a mouse colon cancer cell line–transplanted tumor mouse model. Our study validated the importance of targeting PRMT5 in tumor treatment, because PRMT5 deficiency enforced Klrg1+ terminal CD8+ T cell development and eliminated antitumor activity.
The place of African belief and germ theory on the causes of human diseases
Authors: Anizoba Emmanuel C.
Published: December 2021

This study looks into the African belief about the mystical causes of diseases and the tenets of Western germ theory. Despite widespread Western medical practices, African people still strongly believe in the mystical causes of diseases. This reveals that as far as the African traditional belief is concerned, Western germ theory cannot satisfy the African belief in the causes of diseases. This is as a result of some of the diseases defying Western healing. The study adopts a qualitative phenomenological research design and descriptive method for data analysis. Personal interview forms a primary source of data collection while the secondary source includes library resources. The study observes that some mystical agents in African cosmology, such as witches and sorcerers, ogbanje, and breaking of taboos are responsible for untimely deaths, infliction of diseases to humankind and other related ailments which are believed to be traditional in nature.Intradisciplinary and/or interdisciplinary implications: The study recommends that hospitals and healthcare centres, within and outside Africa, should take into consideration the mystical agents as well as the pathogenic agents for good and efficient healing.

Published: December 2021

Aim:

To estimate the standard uptake values (SUVs) of Tc-99m methylene-diphosphonate (Tc-99m MDP) from normal skeletal sites in breast cancer patients using quantitative single-photon emission computed tomography (SPECT).

Materials and Methods:

A total of 60 breast cancer patients who underwent Tc-99m MDP SPECT/CT study at different postinjection acquisition times were included in this study. Based on postinjection acquisition time, patients were divided into four study groups (n_15 each), i.e. Ist (2 h), IInd (3 h), IIIrd (4 h), and IVth (5 h). Image quantification (SUVmax and SUVmean) was performed using Q.Metrix software. Delineation of volume of interest was shaped around different bones of the skeletal system.

Results:

The highest normal SUVmax and SUVmean values were observed in lumber and thoracic vertebra (8.89 ± 2.26 and 2.89 ± 0.58) for Group I and in pelvis and thoracic (9.6 ± 1.32 and 3.04 ± 0.64), (10.93 ± 3.91 and 3.65 ± 0.97), (11.33 ± 2.67 and 3.65 ± 0.22) for Group II, III and IV, respectively. Lowest normal SUVmax and SUVmean values were observed in humerus and ribs (3.22 ± 0.67 and 0.97 ± 0.18), (5.16 ± 1.82 and 1.18 ± 0.16) for Group I, IV, and in humerus (3.17 ± 0.58 and 0.85 ± 0.26), (3.98 ± 1.12 and 1.04 ± 0.28) for Group II and III, respectively. Significant difference (P < 0.05) noted in SUVmax for sternum, cervical, humerus, ribs, and pelvis with respect to time. However, significant difference (P < 0.05) noted in SUVmean for all skeletal sites with respect to time.

Conclusions:

Our study shows variability in normal SUV values for different skeletal sites in breast cancer patients. Vertebral bodies and pelvis contribute highest SUV values. Time dependency of SUVs emphasizes the usefulness of routinely acquired images at the same time after Tc-99m MDP injection, especially in follow-up studies.

Published: December 2021

Lymphomas represent common hematological malignancy, and depending on site, they are classified as nodal or extranodal lymphoma. The term extranodal disease refers to lymphomatous infiltration of anatomic sites other than the primary lymphatic sites; however, the diagnosis of primary versus secondary extranodal lymphoma remains challenging. Among the extranodal locations, gastrointestinal system is the most frequent site. The involvement of the stomach, small intestine, and colon is noted. Rectum as primary site for lymphoma is rare in adults and extremely rare in children. We describe a case of primary rectal lymphoma (high-grade B-cell non-Hodgkin's lymphoma) in 11-year-old child. We believe that reporting this case will add to the data about clinical presentation, radiological, nuclear medicine findings, and treatment approaches of primary rectal lymphoma.

Published: December 2021

Protected areas are the most frequently used tool for the mitigation of threats to biodiversity. However, without effective management, the creation of new protected areas may be ineffective. In Brazil, protected areas must have both a governing body (consultative or deliberative council) and an official management plan. Here, we analyzed general trends and patterns in the approval of the management plans for Brazilian federal protected areas. We considered all federal protected areas, and compiled data on (i) the year the area was created, (ii) the type of protected area (integral protection vs. sustainable use), (iii) year its management plan was approved, (iv) year in which the management plan was revised after its approval, (v) total area (in hectares), and (vi) the biome in which the area is located. We stablished three groups of protected area: 1) Group A: protected areas created prior to 1979, 2) Group B: protected areas created between 1979 and 1999, and 3) Group C: protected areas created between 2000 to the present time. Finally, we tested whether time for the approval of the management plan suffered a simultaneous effect of the type of biome and type of categories of protected area (strictly protected vs. sustainable use areas). We found 211 (63.17% of the 334) protected areas with management plan. On average, the time taken for the creation and approval of a management plan far exceeds the deadlines (5 yrs.) defined under current Brazilian law. All Brazilian biomes are poorly covered by protected areas with effective management plans, with the highest and lowest value observed in the Pantanal (100%) and Caatinga (46.42%), respectively. Our results suggest that the effectiveness of many federal protected areas in Brazil can be reduced considerably by the lack of a management plan, with deleterious consequences for the country’s principal conservation strategies.

Authors: SOYOYE Babatunde
Published: December 2021

The continuous increase in the cost of fuel and the effect of emission of gases from burned fuel into the atmosphere when operating engine powered lawn mower has necessitated the use of the abundant solar energy from the sun as a power source of a lawn mower. A solar powered lawn mower was designed, fabricated and assembled on the basis of the general principle of mowing. The components of the lawn mower are; direct current (DC) motor, rechargeable battery, solar panel, galvanized steel blade of various thicknesses and shapes, and a speed controller. The required torque needed to drive the galvanized steel blade was achieved through the DC motor. The speed of the DC motor was controlled by the speed controller with the resistance in the circuit and allowed the motor to drive the blade at varied speeds. The battery recharged through the solar charging circuit, which comprises of a solar panel and charge controller. Performance evaluation was conducted on the developed mower with various thicknesses (1 mm, 1.5 mm and 2 mm) and shapes of the cutting blade (two, three and four blades). It was found that the cutting efficiency of the mower ranges from 70.50% - 84.10%, also the cutting capacity ranges from 0.05 ha h-1 - 0.27 ha h-1, the uncut area was also found to range from 15.90% - 29.50%.

Published: December 2021

Soil heavy metals pollution is a major global threat, because of its impact to plants, animals, and the soil geotechnical properties. Geostatistical method was used to investigate the spatial distributions of aluminum and lead within a section of the Delta State University of Science and Technology, Ozoro, Nigeria. A total area of 1 km2 (100 hectares) was covered within the school environment. Twenty -five (25) topsoil samples were collected, at the end of the dry season (March 2021); when the water table in the study area was very low. The lead and aluminum concentrations of the 25 samples were measured by using the Association of Official Analytical Chemists (AOAC) approved methods. Using a geostatistical tool, the lead and aluminum concentrations and distribution in the soil were plotted on predication maps. The maps revealed irregular spatial distributions of lead and aluminum ions within the study area. The lead concentration was highest at the North-central region of the study area; while lead concentration was lowest at the Eastern region of the study area. In terms of the aluminum metal, the highest aluminum concentration was observed in the North eastern region; while aluminum concentration was lowest at the South western region. Data obtained from this study will be useful for agricultural and civil engineering purposes, mainly in the area of decision-making.

Los límites de la vida rural: naturaleza y violencia
Authors: Riera Carla
Published: December 2021

Aquest article estudia la representació literària dels espais que envolten la llar analitzant l’ús d’imatges naturals vinculades en relació amb l’enclaustrament femení. En particular, s’investiga com esdevenen símbols dels valors atribuïts a la dona —des de la síntesi que en fa Elizabeth Grosz—, sobretot en relació amb la fecunditat. S’utilitzen nocions de Michel Foucault sobre el poder per analitzar com els mecanismes de control creen i gestionen aquests espais limítrofs. Per a il·lustrar-ho, s’examinen casos dels «drames rurals» de l’autora Víctor Català —relats breus en català publicats entre 1902 i 1930—, on l’alteració de certes imatges recurrents permet reflexionar sobre la gradació de violències que recauen en la dona. Es mostrarà com les tensions entre individus s’inscriuen en certs espais naturals que van des de l’hort fins al bosc.
Bruja gestante. Criminalización patriarcal del cuerpo (no)materno en el acceso al aborto en Argentina
Authors: Rozanski Noelia
Published: December 2021

El discurso criminológico de la Inquisición condensado en el Malleus Maleficarum en el siglo XV y heredero de prácticas de persecución y tortura desarrolladas a partir del siglo XII, se valió de la imagen de la bruja para ser funcional a sectores de poder en su empresa de aniquilar y diezmar poblaciones enteras e imprimir en los cuerpos modos de ser y actuar necesarios para el desarrollo de un sistema económico que requería un modelo articulado y controlado de producción/reproducción: el capitalismo. Es objetivo de este trabajo analizar la criminalización patriarcal del cuerpo (no)materno en el acceso al aborto en Argentina y las continuidades del discurso demonológico del siglo XV a partir del caso Belén, una mujer que entre 2014 y 2017 estuvo 29 meses detenida por un aborto espontáneo acusada de matar a su “hijo”. Para el abordaje del caso, nos valdremos de los aportes teóricos de distintas autoras feministas, y a partir de allí indagaremos cómo el poder punitivo del Estado atraviesa el cuerpo con tecnologías de biopoder, le imprime modos de ser, pensar y actuar, imperativos y prohibiciones, y demoniza con su impronta patriarcal la parte “maldita”, subversiva e infame de lo que en este trabajo hemos llamado “bruja gestante”.

Published: December 2021

Under irradiation of crystals, atomic vibrations of the lattice that are large enough in amplitude so that the linear approximation and therefore the conventional phonon description of the lattice is not enough. At the same time, these vibrations are localized and can travel long distances in a crystal lattice [1, 2]. In metals and other crystals, they are called discrete breathers (DBs), which are the secondary products of irradiation damage, the primary one being the creations of defects that involve atom displacements to produce point and extended defects, which results in radiation induced hardening (RIH). A part of the remaining energy transforms in DBs before decaying into pho-nons. Thus, while a material is being irradiated in operational conditions, as in a reactor, a considerable amount of DBs with energies of the order of one eV is produced, which helps dislocations to unpin from pinning centers, pro-ducing Radiation Induced Softening (RIS), which opposes RIH [3, 4]. This effect is investigated under (in-situ) im-pulse and steady-state electron irradiation.

GAS TEMPERATURE MEASUREMENT IN THE ACTIVE ZONE OF STREAMER DISCHARGE UNDER DIFFERENT APPLIED VOLTAGES
Authors: Bolotov O.V. , Golota V.I. , Taran G.V.
Published: December 2021

The experimental results on the gas temperature measurement in the active zone of streamer discharge in air at the atmospheric pressure are presented. The gas temperature value was obtained by the optical method for measur-ing the relative intensity of the rotational lines for the radiation of the second positive (II+) system of molecular ni-trogen, transition bands (С3Пu(0)→B3Пg(0)). It was found that in discharge gap d = 8 mm, depending on the ap-plied voltage (in the range of 6.1…7.8 kV with a step of 0.2 kV), the gas temperature varied from 609 to739 K. The unevenness of the gas temperature change in the active zone of discharge with the increase in the applied voltage is shown. This may be related to the possible changes in the rotational state of nitrogen molecules upon excitation of their electronic state by electrons.
Frederick Douglass, Copyright, and the British Press, 1845-47
Authors: Easley Alexis
Published: December 2021

In 1845, Frederick Douglass established his copyright to the Narrative of the Life in the United States in order to receive just remuneration for his work. Yet Douglass also relied on a lack of international copyright law to disseminate his abolitionist message to a transatlantic audience. While Douglass made use of both copyright-protected and free-circulating forms of publication to reach a broad audience, he could not always control how his work and image would be reprinted and adapted in the transatlantic press. During his 1845-7 lecture tour, British periodicals and newspapers creatively recontextualised, abridged, and plagiarised his Narrative in articles and reviews. These forms of reuse were conventional in the publishing world of the 1840s, yet when viewed from a modern perspective, they seem to echo the exploitative practices associated with the American slave system.

The demand for coconut water and coconut oil is increasing thus there is interest in expanding coconut cultivation. Coconut is primarily planted on approximately 28,500 acres by more than 1,400 farmers along the Guyana coastline with the Atlantic Ocean and in the Pomeroon Riverain area. Tall types (e.g. Jamaica Tall) are planted for oil while Dwarf types (e.g. Malaysian Dwarf Green, Suriname Brown) are planted primarily for water. At least 50% of the Tall type population is more than 50 years old and needs to be replanted to increase productivity. Farmers traditionally collect seedlings growing from dropped nuts at the base of trees without attention to prolificacy. Since a coconut tree productive life is more than 50 years, the economic impact of this practice can be significant. Via training programs, CARDI is encouraging the structured production of coconut seedlings to increase yields. This project aims to enhance the supply of quality seedlings using local seed nuts. Mother palms that display prolific bearing habits, resistance to pest and diseases plus vigorous growth habit were geotagged and recorded in a database. Seed nuts were purchased from farmers who own these trees and subsequently distributed (in batches of 400) to ten selected (age, gender, location) lead farmers to establish coconut seedling nurseries. Each lead farmer was assisted by 10 second ring farmers in the establishment of their nurseries under CARDI supervision. Results to date show that weed control and irrigation were important nursery activities. Some nurseries needed to be fenced to counter damage by animals (cows, sheep, goats). Average germination of seed nuts was approximately 50%. Available seedlings are being distributed to second ring farmers and lead farmers. CARDI will continue the national survey to identify outstanding mother palms. Measures to increase average germination must also be implemented. Local coconut seedling nurseries should therefore be encouraged as their “success” will alleviate the pressure to import seed nuts thus avoiding the attendant risk of introducing exotic diseases (e.g. lethal yellowing disease) into Guyana. Further, given that a coconut palm will live 50 to 70 years, the importance of carefully selecting premium quality coconut seedlings as a bedrock to develop and grow the industry cannot be over emphasized.

Nowadays, academic dishonesty has become an endemic academic phenomenon because students seem to be treating cheating on tests or examinations as a common thing. Therefore, this study was conducted to investigate the intentions for engaging in academic dishonesty among degree students in public higher education    in Malaysia by explaining the most prevalent predictors of academic dishonesty, which are attitude, subjective norms, perceived behavioral control, ethical behavior, and moral reasoning. A total of 346 respondents were involved in this study, composed of degree students from accountancy, surveying, plantation, applied science, marine science, business and management, computer science, and sports science programs. Results illustrate that subjective norms were found insigniﬁcantly related to the intentions to be involved in academic dishonesty because the respondents have treated cheating as common norm and considered it not weird to be involved in cheating. Attitude, perceived behavioral control, ethical belief, and moral reasoning were found to be signiﬁcantly related to academic dishonesty intentions.
