Current State of Molecular and Serological Methods for Detection of Porcine Epidemic Diarrhea Virus
Authors: Olech Monika
Published: September 2022

Porcine epidemic diarrhea virus (PEDV), a member of the Coronaviridae family, is the etiological agent of an acute and devastating enteric disease that causes moderate-to-high mortality in suckling piglets. The accurate and early detection of PEDV infection is essential for the prevention and control of the spread of the disease. Many molecular assays have been developed for the detection of PEDV, including reverse-transcription polymerase chain reaction (RT-PCR), real-time RT-PCR (qRT-PCR) and loop-mediated isothermal amplification assays. Additionally, several serological methods have been developed and are widely used for the detection of antibodies against PEDV. Some of them, such as the immunochromatography assay, can generate results very quickly and in field conditions. Molecular assays detect viral RNA in clinical samples rapidly, and with high sensitivity and specificity. Serological assays can determine prior immune exposure to PEDV, can be used to monitor the efficacy of vaccination strategies and may help to predict the duration of immunity in piglets. However, they are less sensitive than nucleic acid-based detection methods. Sanger and next-generation sequencing (NGS) allow the analysis of PEDV cDNA or RNA sequences, and thus, provide highly specific results. Furthermore, NGS based on nonspecific DNA cleavage in clustered regularly interspaced short palindromic repeats (CRISPR)–Cas systems promise major advances in the diagnosis of PEDV infection. The objective of this paper was to summarize the current serological and molecular PEDV assays, highlight their diagnostic performance and emphasize the advantages and drawbacks of the application of individual tests.
Watermarking and Encryption for Holographic Communication
Authors: He Zehao , Liu Kexuan , Cao Liangcai
Published: September 2022

Holographic communication is a three-dimensional (3D) video communication technology based on computer-generated holograms (CGHs) which has the potential to give users a more realistic visual perception. As this is an emerging field, the encrypted encoding and decoding methods in holographic communication have not been widely studied. In this work, a watermarking and encryption method for holographic communication is proposed. A watermark is inserted into the original image using the discrete cosine transform before the calculation of the CGH, while a secret key is employed to produce the encrypted CGH during the holographic calculation. Through the proposed watermarking and encryption method, the signal of holographic communication is difficult to decrypt. Even if the signal is decrypted, the source of the leak is easy to trace due to the existence of the watermark. The watermarking and encryption method can provide a practical solution for the privacy protection and copyright protection of 3D video communication.

Authors: Shi Wenjie , Gao Lin , Zhang Long , Feng Zhiwei , Fang Fan , Xia Guo
Published: September 2022

In this study, we propose a method of evaluating the spectral resolution of crossed-asymmetric Czerny-Turner spectrometers by comparing the impact of different slit functions on the optical transfer function, and different slit widths, through simulation and experiments. The results show that, the Gaussian function is suitable for narrower slit widths, such as 25 μm, and the rectangle function or convolution of slit-scattering function with rectangle function is suitable for wider slit widths, such as 50 μm, 150 μm, and 200 μm. The proposed method can provide guidance in the evaluation of spectral resolution in the preliminary optical design process of spectrometers.
An All-Dielectric Color Filter, with a Wider Color Gamut
Authors: Zeng Lizhen , Yang Yuting , Xiao Gongli
Published: September 2022

Due to their extraordinary abilities to manipulate light propagation at the nanoscale, dielectric resonators that generate electric and magnetic Mie resonances for minimal optical loss have recently attracted great interest. Based on an all-dielectric metasurface, made of H-type silicon nanoarrays, this study proposed and constructed a visible-wavelength-range color filter, with high-quality Mie resonance and the ability to synthesize new colors. Using the finite-difference time-domain (FDTD) approach, we can create a larger color gamut by modifying the H-type array’s structural properties. The all-dielectric color filter suggested has a high color saturation and narrow bandwidth. The Mie resonance can be adjusted by manipulating the structural characteristics. By translating the reflectance spectrum into color coordinates and using the CIE1931 chromaticity diagram, a wide range of colors can be generated. This color filter offers a larger color range and saturation than other color filters. We produced color passband filters that span the visible spectrum using Mie resonator arrays, based on an H-type nanoresonator. This technology could have many applications, including high-resolution color printing, color-tunable switches, and sensing systems.

Published: September 2022

Metasurface absorbers are already used in many laser applications. To achieve laser stealth, a dual-band guided-laser absorber is presented in this paper. The absorber is composed of periodic silicon squares on a silicon film and a nickel layer. Under normal incidence, the absorber has two absorption peaks at wavelengths of 1.55 μm and 1.064 μm, with absorption rates higher than 94.4%. For wavelength-tunable 1.55 μm lasers with a large wavelength tuning range of ±50 nm, the absorption rate is still as high as 90%. Plasmonic resonance theory, as well as FDTD simulations, are used to design and study the absorber. It is found that the absorber is independent of the incident polarization and tolerant to the incident angle. The design method is flexible, and the absorber is easy to manufacture.

Even though it is a forest native plant, there are already several studies evaluating the small genome of Jatropha curcas L., which belongs to the Euphorbiaceae family, and may be an excellent representative model for the other plants from the same family. Jatropha curcas L. plant has fast growth, precocity, and great adaptability, facilitating silvicultural studies, allowing important information to be obtained quickly, and reducing labor costs. This information justifies the use of the species as a model plant in studies involving the reproduction of native plants. This study aimed to evaluate the possibility of using Jatropha curcas L. as a model plant for studies involving native forest plants and establish possible recommendations for the vegetative propagation of the species using hardwood cuttings. The information collected can be helpful to other native forest plant species, similar to Jatropha curcas L. To this end, the effects of hardwood cutting length (10, 20, and 30 cm) and the part of the hardwood cuttings (basal, middle, and apex) were evaluated. Moreover, the influence of immersing the hardwood cuttings in solutions containing micronutrients (boron or zinc) or plant regulators (2,4-D, GA3) and a biostimulant composed of kinetin (0.09 g L−1), gibberellic acid (0.05 g L−1), and 4-indole-3-butyric acid (0.05 g L−1). The experiments were carried out in duplicates. In one duplicate, sand was used as the substrate, and rooting evaluations were made 77 days after planting. In another duplicate, a substrate composed of 50% soil, 40% poultry litter, and 10% sand was used, and the evaluations of the saplings were performed 120 days after planting. The GA3 solutions inhibited the roots’ and sprouts’ emissions, while immersion in 2,4-D solution increased the number of primary roots at 77 days after planting. The hardwood cuttings from the basal part of the branch had the best results for producing saplings.

Published: September 2022

The U-box E3 (PUB) family genes encode the E3 ubiquitin ligase enzyme, which determines substrate specific recognition during protein ubiquitination. They are widespread in plants and are critical for plant growth, development, and response to external stresses. However, there are few studies on the functional characteristic of PUB gene family in the important staple crop, maize (Zea mays L.). In this study, the PUB gene in maize was aimed to identify and classify through whole-genome screening. Phylogenetic tree, gene structure, conserved motif, chromosome location, gene duplication (GD), synteny, and cis-acting regulatory element of PUB member were analyzed. The expression profiles of ZmPUB gene family in maize during development and under abiotic stress and hormones treatment were analyzed by the RNA-seq data. A total of 79 PUB genes were identified in maize genome, and they were stratified into seven categories. There were 25 pairs of segmental duplications (SD) and 1 pair of tandem duplication (TD) identified in the maize PUB gene family. A close relationship was observed between the monocot plant maize and rice in PUB gene family. There were 94 kinds of cis-acting elements identified in the maize PUB gene family, which included 46 biotic- and abiotic-responsive elements, 19 hormone-responsive elements, 13 metabolic and growth-related elements. The expression profiles of maize PUB gene family showed characteristics of tissue specificity and response to abiotic stress and hormones treatment. These results provided an extensive overview of the maize PUB gene family.

Published: September 2022

Brassica napus inap cytoplasmic male sterility (CMS) is a novel sterile line with potential application in rapeseed hybrid breeding. Sterile cytoplasm was obtained from Isatis indigotica through somatic fusion and then recurrent backcrossing with B. napus. Previous studies have shown that inap CMS abortion occurred before the stamen primordia (stage 4–5), but the genetic mechanism of sterility needs to be studied. RNA-seq analyses were performed on the floral buds at two stages (0–5 and 6–8), before and after the formation of stamen primordium. As a result, a total of 1769 and 594 differentially expressed genes (DEGs) were detected in the CMS line compared to its maintainer line at the two stages, respectively. In accordance with the CMS phenotype, the up- and downstream regulators of the stamen identity genes AP3 and PI were up- and downregulated in the CMS line, respectively. Furthermore, isobaric tags for relative and absolute quantitation (iTRAQ) analysis showed that a total of 760 differentially abundant proteins (DAPs) were identified in flower buds at stages 0–8, and most of the proteins related to the anther development, oxidative phosphorylation, and programmed cell death (PCD) were downregulated in inap CMS. In combined transcriptomic and proteomic analysis, a total of 32 DEGs/DAPs were identified, of which 7 common DEGs/DAPs had the same expression trend at stage 0–8 of flower development. The downregulation of genes related to the energy deficiency, hormone signal transduction, and the maintenance of mitochondrial metabolic homeostasis at stage 0–5 might disturb the normal differentiation of stamen primordium, resulting in carpelloid stamen of inap CMS. The study will help provide insights into the molecular mechanism of this new male sterility.

Published: September 2022

Salt stress is one of the most common abiotic kinds of stress. Understanding the key mechanisms of salt tolerance in plants involves the study of halophytes. The effect of salinity was studied in two halophytic annuals of Chenopodiaceae Salicornia perennans Willd. and Climacoptera crassa (Bied.) Botsch. These species are plants with C3 and C4-metabolism, respectively. We performed a comprehensive analysis of the photosynthetic apparatus of these halophyte species at different levels of integration. The C3 species S. perennans showed larger variation in leaf functional traits—both at the level of cell morphology and membrane system (chloroplast envelope and thylakoid). S. perennans also had larger photosynthetic cells, by 10–15 times, and more effective mechanisms of osmoregulation and protecting cells against the toxic effect of Na+. Salinity caused changes in photosynthetic tissues of C. crassa such as an increase of the mesophyll cell surface, the expansion of the interface area between mesophyll and bundle sheath cells, and an increase of the volume of the latter. These functional changes compensated for scarce CO2 supply when salinity increased. Overall, we concluded that these C3 and C4 Chenopodiaceae species demonstrated different responses to salinity, both at the cellular and subcellular levels.

Published: September 2022

Climate warming in the Antarctic tundra will affect locally dominant cryptogams. Being adapted to low temperatures and freezing, little is known about the response of the polar lichens’ primary photochemistry to warming and desiccation. Since 2008, we have monitored the ecophysiological responses of lichens to the future warming scenario during a long-term warming experiment through open top chambers (OTCs) on Fildes Peninsula. We studied the primary photochemical response (potential Fv/Fm and effective efficiency of photosystem II YPSII) of different lichen taxa and morphotypes under desiccation kinetics and heat shock experiments. As lichens grow slowly, to observe changes during warming we methodologically focused on carbon and nitrogen content as well as on the stable isotope ratios. Endemic Himantormia lugubris showed the strongest effect of long-term warming on primary photochemistry, where PSII activity occurred at a lower %RWC inside the OTCs, in addition to higher Fv/Fm values at 30 °C in the heat shock kinetic treatment. In contrast, Usnea aurantiaco-atra did not show any effect of long-term warming but was active at a thallus RWC lower than 10%. Both Cladonia species were most affected by water stress, with Cladonia aff. gracilis showing no significant differences in primary photochemical responses between the warming and the control but a high sensibility to water deficiency, where, at 60% thallus RWC, the photochemical parameters began to decrease. We detected species-specific responses not only to long-term warming, but also to desiccation. On the other hand, the carbon content did not vary significantly among the species or because of the passive warming treatment. Similarly, the nitrogen content showed non-significant variation; however, the C/N ratio was affected, with the strongest C/N decrease in Cladonia borealis. Our results suggest that Antarctic lichens can tolerate warming and high temperature better than desiccation and that climate change may affect these species if it is associated with a decrease in water availability.

Published: September 2022

Understanding how functional traits influence community assemblage and functioning is crucial for assessing the effects of global change on vegetation composition. We studied the functional composition (i.e., plant size (SIZE), leaf area (LA), specific leaf area (SLA), and leaf dry matter content (LDMC)) of a xerophile pasture and a mesophile grassland in southern Italy, and recorded species richness (SR), plant cover (COV) and flowering rates (FLOW) over a 7-year period. Both communities revealed the dominance of stress-tolerators, probably reflecting an adaptation to the Mediterranean climate. The functional classification of species distinguished three groups. Species from the mesophile community had larger SIZE and LA, while those from the xerophile pasture showed higher LDMC; SLA was not connected to the source community. Community-level analyses confirmed such patterns, but with higher SLA in the mesophile grassland. While SR was comparable, COV and FLOW varied between the communities. At the species level, LDMC was positively related to FLOW and the inter-annual variability of COV and FLOW. At the community level, SIZE, LA and SLA were positively related to COV, while LDMC was positively related to FLOW. Trait variations can significantly contribute to the xerophile–mesophile shift in Mediterranean mountain vegetation, by regulating the productivity of species and communities in the two contexts and, possibly, their responsiveness to global change.
Propagation Methods Decide Root Architecture of Chinese Fir: Evidence from Tissue Culturing, Rooted Cutting and Seed Germination

Published: September 2022

The root is the main organ of a plant for absorbing resources and whose spatial distribution characteristics play an important role in the survival of seedlings after afforestation. Chinese fir (Cunninghamia lanceolata) is one of China’s most important plantation species. To clarify the effects of propagation methods on root growth and spatial distribution characteristics of Chinese fir trees, sampled trees cultivated by seed germination, tissue culture, and asexual cutting of Chinese fir were taken as the research objects. The root morphology, geometric configuration, and spatial distribution characteristics of different trees were analyzed. The influence of geometric root morphology on its spatial distribution pattern was explored by correlation analysis, and the resource acquisition characteristics reflected by the roots of Chinese fir trees with different propagation methods are discussed. The main results showed that the root mean diameter (1.56 mm, 0.95 mm, and 0.97 mm), root volume (2.98 m3, 10.25 m3, and 4.07 m3), root tip count (397, 522, and 440), main root branch angle (61°, 50° and 32°) and other geometric configurations of Chinese fir under seed germination, tissue culture and rooted cutting respectively, were significantly different, which resulted in different distribution characteristics of roots in space. Chinese fir seed germination had noticeable axial roots, and the growth advantage was obvious in the vertical direction. A fishtail branch structure (TI = 0.87) was constructed. The shallow root distribution of tissue culture and rooted cutting was obvious, and belonged to the fork branch structure (TI = 0.71 and 0.74, respectively). There was a tradeoff in the spatial growth of the root system of Chinese fir trees with different propagation methods to absorb nutrients from heterogeneous soil patches. A negative correlation was present between the root system and root amplitude. There was an opposite spatial growth trend of Chinese fir trees with different propagation methods in the vertical or horizontal direction. In conclusion, selecting suitable propagation methods to cultivate Chinese fir trees is beneficial to root development and the “ideal” configuration formation of resource acquisition to improve the survival rate of Chinese fir afforestation.

Authors: Cecchini Simone
Published: September 2022

Las múltiples desigualdades económicas y sociales que caracterizan a los países de América Latina y el Caribe conspiran en contra de su desarrollo sostenible y tienen una relación directa con la actual crisis económica, social y sanitaria. La pandemia de la COVID-19 y la guerra en Ucrania, sumadas a las brechas estructurales, están dibujando una tormenta perfecta de bajo crecimiento, desocupación, elevada inflación, aumento de la pobreza, el hambre, la desigualdad, el malestar social y la polarización política. A esto hay que sumar los desafíos sociodemográficos que conllevan el rápido envejecimiento, la fuerte urbanización y la creciente inmigración irregular en la región. Sin embargo, la pandemia ha mostrado también cuán importantes son las políticas públicas para proteger a la población, sea por medio de la vacunación o de las transferencias monetarias de emergencia. Ahora es el momento de reconstruir con igualdad y sostenibilidad, apuntando a la creación de verdaderos Estados de bienestar, en los cuales suficientes niveles de tributación e inversión social permitan implementar políticas públicas universales y sensibles a las diferencias en materia de protección social, cuidado, salud, educación e inclusión digital.

Authors: Armijos Cuenca María José , Culcay Villavicencio Iván Patricio
Published: September 2022

El trabajo infantil es una de las realidades que ha afectado la humanidad desde hace décadas. Por ello, diferentes instituciones internacionales han desarrollado normativas para regularla. En el Estado ecuatoriano, algunas de sus normativas previenen la explotación laboral de los menores; como el Código de la Niñez y Adolescencia, así como la Constitución o el Código del Trabajo, las cuales buscan preservar la dignidad y desarrollo integral del menor. Como objetivo principal se analizó la vulneración del desarrollo integral del menor, por el trabajo infantil en época de pandemia. Se aplicó un enfoque cualitativo, siguiendo un método descriptivo para abordar principalmente el trabajo infantil como punto de partida y su acción negativa en el derecho del interés superior del niño. Se concluyó que la falta de acción jurídica presenta un pilar importante en el aumento de la vulneración de los derechos de los niños, niñas y adolescentes.
Early Middle Ordovician Corals from Western Utah

Published: September 2022

Two species from western Utah are among the oldest known corals from North America. The older of the two, Lichenaria simplex (?) (Bassler) is cerioid with small corallites that lack both septae and, tabulae. It is described from two small specimens from the Lehman Formation of the Ibex area where it occurs in the Whiterockian Pseudoolenoides acicauda trilobite zone (Zone N). The younger species, Eofletcheria utahia n. sp. ranges from cerioid and phaceloid to dendroid, lacks septae, but has well defined complete tabulae. It seems likely that E. utahia has been identified in faunal listings from western U.S. Middle Ordovician occurrences both as Lichenaria and as Eofletcheria depending on the portion of the colony that was examined. Eofletcheria utahia is the most common fossil in the Crystal Peak Dolomite in western Utah. It occurs there with the brachiopods Kirkina millardensis Salmon and Orthambonites perplexus Ross in Zone 0 of Hintze. Conodonts from zone o indicate that it is Chazyan

La presente investigación tiene como objetivo utilizar la Chakana pregunta para redactar un texto argumentativo con base en el análisis vertical central. Se trata de un estudio cualitativo-propositivo y experimental que describe la Chakana pregunta como estrategia didáctica que desarrolla el pensamiento crítico, a través de tres preguntas seleccionadas de nueve. Los resultados son significativos porque, mediante tres preguntas, se desarrolla el pensamiento crítico, considerando el aporte de Paulo Freire en la interpretación crítica de Zaylín Brito Lorenzo (texto de 665 palabras). Se ha utilizado 18 fuentes de consulta, de las cuales el 50 % son libros. Entre las citas textuales, solo dos superan las 40 palabras con el fin de lograr que el pensamiento crítico sea el resultado. Se concluye que la Chakana pregunta es una estrategia didáctica que desarrolla el pensamiento crítico a través del ejercicio de la autonomía al seleccionar solo uno de los seis niveles de análisis. Las preguntas seleccionadas se convirtieron en un espacio para la crítica del pensamiento de Paulo Freire y las relaciones establecidas entre la educación popular y el sentido libertario dentro de una escuela emergente y libertaria en la actualidad.

Producing quality in writing is not easy to do. The selection of vocabulary in writing affects the quality of writing. There are still difficulties in writing, especially for students. The students are still lack of the understanding of lexical cohesion. Regarding the problems identified, this research aims to analyze the employment of lexical cohesion in magazine articles. The results of this research show how article writers, which are the experts in writing published works for a large audience, make their writing cohesive. This research uses a qualitative descriptive method to explain the lexical cohesion occurring in the magazine articles. After identifying and analyzing the data, it is found that all lexical cohesion types have occurred 307 times in the magazine articles: repetition, synonymy, antonymy, hyponymy, meronymy, and collocation. Synonymy is the most frequently used lexical cohesion type in the magazine articles, followed by collocation. The use of synonymy and collocation creates the cohesiveness of the text. The magazine articles become rich in vocabulary, not monotonous, and understandable to the readers.

Asimismo, enfatizo la necesidad de orientarla por el interés colectivo y responder a la ética utilitarista - instrumentista actual, producto del período capitalista y neoliberal. Para lograr lo anterior, convoco algunas de las principales concepciones éticas filosóficas relativas a la época, por ejemplo, durante la Grecia clásica, el Renacimiento, la Segunda Guerra Mundial o después de la llegada de los pioneros a Norteamérica. En este recorrido se destacan la analogía beuchotiana y la concepción de la vida cotidiana propuesta por Agnes Heller, las cuales se incluyen magistralmente en la construcción de la llamada ética analógica de la vida cotidiana del Doctor Primero.
Incorporación de la dimensión estética en la educación superior: diálogo con Luis Eduardo Primero
Authors: Porter Galetar Víctor Luis
Published: September 2022

Objetivo: Destacar la importancia de incorporar la poesía en todos los niveles y campos de la educación superior. Metodología: Discurso dialógico argumentativo. Conclusión: Se trata de incorporar una visión estética a la relación maestro/alumno. Esta estética se ubica en el “pensar bien”, íntimamente vinculado al “sentir bien”, es decir, no sólo en el pensamiento, sino asimismo en la sensibilidad. El docente puede estimular al estudiante para que con un ejercicio introspectivo ponga atención a su propio potencial de artista, al poeta que todos somos o llevamos en nosotros, y que deberíamos descubrir, reconocer y potenciar, para incorporarlo a nuestra estrategia didáctica y principios pedagógicos desde las epistemologías del Sur.
Significar bien el saber contemporáneo
Authors: Primero Rivas Luis Eduardo
Published: September 2022

Objetivo: Proponer una epistemología que genere una ciencia y una educación nuevas desde la frontera del conocimiento del Sur. Metodología: Análisis-síntesis teórica. Resultados: Desde el enfoque de una filosofía primigenia, se analiza el concepto de conocimiento y sus tipos, entre los que se encuentra el conocimiento científico. Después, se caracteriza el conocimiento actual, en el que hay una lucha contra la tendencia histórica del positivismo a partir de la propuesta de nuevas epistemologías situadas en la frontera cognitiva de la época y surgidas en el espacio cultural del Sur. Se reivindica el valor de la filosofía, denostada por el pensamiento positivista y neoliberal; una filosofía que promueva una mejor manera de significar la realidad, tanto por su sentido ético, como por la necesidad de tener una mejor conceptuación de la ciencia. Se propugna un concepto de educación más amplio que el meramente escolar, que excluye los conocimientos para la vida creando idologías, fetichizaciones y mistificaciones enceguecedoras que potencian los diversos males y dolencias de nuestra época. Conclusión: Superar la enajenación y sus males supone crear una renovada libertad y promover una mayor racionalidad, pues urge obtener beneficios ante los avances de la barbarie, tangibles en demasiados ámbitos del mundo actual.
Molecular detection and risk factors associated with Trichomonas vaginalis infection among pregnant women in Osogbo and Ede, Southwest Nigeria
Authors: Onakhinor Sandra O.
Published: September 2022

Background: Trichomoniasis is the most prevalent curable sexually transmitted disease globally. This study provides information on the prevalence and risk factors of Trichomoniasis among pregnant women in primary healthcare centres in Osogbo and Ede areas in Osun State, Nigeria.
Methodology: High vaginal swab samples were obtained from 145 consenting pregnant women using sterile swab sticks and analysed through microscopic examination and PCR diagnostic techniques. Questionnaires were administered to investigate the participants’ socio-demographic characteristics, hygiene practices, and knowledge and practices (KAP) about trichomoniasis.
Result: The overall prevalence of trichomoniasis was 0%, as no trophozoite was detected in any sample. There was no statistical difference between the number of sexual partners, occupation, family type, and previous sexually transmitted infections. Many of the respondents (89.7%) were ignorant of this disease and its transmission mode.
Conclusion: The molecular technique employed in this study has further confirmed the zero prevalence of trichomoniasis in the study area and may be a promising diagnostic test.
Update on the Status of urogenital schistosomiasis in Some Communities of Ebonyi State, Nigeria
Authors: Nworie Chika John
Published: September 2022

Background: Schistosomiasis is one of the most common parasitic infections in the world, particularly in sub-Saharan Africa, ranking second only to malaria in terms of its socio-economic and public health importance in tropical and subtropical areas. There is an urgent need for updated information on the intensity of the disease at the community level to ensure effective disease monitoring.
Materials and methods: The study was carried out in sixteen communities in the four local government areas of Ebonyi State. A total of 1,800 urine samples were collected from people of all ages randomly selected for this study. Urine samples were examined for Schistosoma haematobium egg using the standard parasitological method of diagnosis. Haematuria was evaluated using reagent test strips.
Results: In this study, 342 (19.0%) persons were infected with S. haematobium. The infection was recorded in all the Communities in the study area, with Enyibichiri having the highest prevalence, n=39 (32.2%), followed by Umuoghara, n = 26 (25.5), while Oshugbu Community had the least prevalence, 5 (6.6%). More males, 225 (20.3%) than females, 117 (16.9%) were significantly infected. Infection prevalence was higher significantly (27.3%) among the age group 11-20 years. Those with light infection intensity 207 (60.5%) were excreting below 50 eggs/10ml urine, 110 (32.2%) had moderate infection intensity excreting between 50-100 eggs/10ml urine while 25 (7.3%) had heavy infection intensity excreting above 100egg/10ml urine. Peak intensity 14 (10.2%) was recorded among 11-20 egg groups. Prevalence of light and moderate intensities varied significantly (P<0 .05) when compared with the prevalence of heavy infection in different age groups, which was not significantly different (P> 0.05). The prevalence of haematuria was 188 (55.0%). The highest prevalence of haematuria (86; 62.3%) was recorded in the age group 11-20 years, while the least was recorded in age 31-40.
Conclusion: Based on the findings of this study, the prevalence of urinary schistosomiasis infection in the Central Ebonyi State falls within the WHO classification of endemicity. Urgent need for decisive interventions through mass chemotherapy, focal application of molluscicides in the water bodies during the dry season and sanitation facilities are recommended. Health education is highly advocated

Introduction

Many studies have focused on the role of programmed death receptor ligand 1 (PD-L1) expression in predicting immunotherapy outcomes. Limited clinical data are available regarding the role of programmed death receptor 1 (PD-1; the PD-L1 receptor) expressing tumor-infiltrating lymphocytes (TILs) in PD-1/PD-L1 antibody responsiveness. However, preclinical studies demonstrate that TILs expressing PD-1 contribute to tumor immune evasion. Methods: This study analyzed the association between TIL-PD-1 status and outcome after immune checkpoint blockade (ICB) therapy. We evaluated 123 patients with various solid tumors treated with monoclonal antibodies targeting the PD-1/PD-L1 signaling axis. Additionally, 8706 solid tumor specimens were assessed for TIL-PD-1 and tumor mutational burden (TMB) status. Results: The presence of PD-1-expressing TILs in tumors was associated with increased median progression-free survival (7.0 vs 1.9 months; p = 0.006) and overall survival (18.1 vs 8.0 months; p = 0.04) after treatment with ICB. TIL-PD-1–positive patients had an objective response rate (ORR) of 41% (95% CI, 24–61; N = 12/29) compared with 17% (95% CI, 4–43; N = 3/17) for TIL-PD-1–negative patients (p = 0.18). Analyzed as continuous variables, TIL-PD-1 and TMB showed a weak correlation in 8706 solid tumor samples (Pearson r = 0.074); when analyzed as categorical variables (cutoffs: TIL-PD-1 ≥ 1% and TMB ≥ 10 mutations/Mb), the two variables are correlated (p < 0.0001). TIL-PD-1–positive status is also associated with enrichment of pathologic variants within several genes, most notably TP53 (adjusted p < 0.05). Conclusion: TIL-PD-1 positivity in tumors (≥ 1%) is associated with significantly longer progression-free and overall survival after ICB. ClinicalTrials.gov ID: NCT02478931
