Published: August 2023

Hiện nay, hệ thống cảm ứng tạo rễ tơ đã và đang được ứng dụng rộng rãi trong nghiên cứu về chức năng cũng như biểu hiện gen và chỉnh sửa hệ gen ở thực vật. Trong nghiên cứu này đã thiết lập được một quy trình hiệu quả cho cảm ứng tạo rễ tơ in vitro và chuyển gen ở giống bạch đàn lai UP54 sử dụng vi khuẩn Agrobacterium rhizogenes. Ảnh hưởng của một số yếu tố bao gồm môi trường nền, điều kiện chiếu sáng, chủng vi khuẩn, loại vật liệu, mật độ vi khuẩn, thời gian lây nhiễm và thời gian đồng nuôi cấy tới hiệu quả tạo rễ tơ và chuyển gen đã được đánh giá. Kết quả thu được cho thấy, hiệu quả cảm ứng tạo rễ tơ cao nhất được ghi nhận khi các đoạn thân được lây nhiễm với dịch huyền phù của chủng vi khuẩn ATCC 15834 ở mật độ OD600nm­ là 0,3 trong thời gian 20 phút, đồng nuôi cấy trong 3 ngày trước khi chuyển sang môi trường MS với ½ thành phần muối đa lượng và đặt trong điều kiện tối. Tỉ lệ chuyển gen thông qua rễ tơ đạt giá trị cao nhất là 26,67%. Các dòng rễ tơ chuyển gen được kiểm chứng thông qua phương pháp nhuộm X-Gluc và PCR với cặp mồi đặc hiệu của gen gus intron và rolD. Kết quả này là tiền đề cho việc kiểm tra nhanh chóng hiệu quả hoạt động của cấu trúc chuyển gen và chỉnh sửa gen ở bạch đàn trong các nghiên cứu tiếp theo.

PR-350-174507-Z01 Guidance on the Use, Specification, and Anomaly Assessment of Modern Linepipes
Authors: Wang Yong-Yi , Jia Dan
Published: August 2023

The information collected and analyzed in this project demonstrates that the minimum requirements in industry standards are not sufficient for real-world loading conditions. More importantly, the "handover" of standards governing different phases of a pipeline's life, from design, material procurement, and construction to operation and maintenance, has gaps and inconsistencies.

Recommendations that are critical to improving industry practice, including updates to standards, are provided in this report. The implementation of these recommendations is expected to greatly reduce the risk of similar failures in the future. They are helpful for responding to the safety advisories from CER and PHMSA.

The recommendations, when implemented, could impact pipe and weld properties which may be a part of overall specifications and requirements. A holistic approach based on sound engineering analysis may be necessary to achieve an optimal balance among various potentially conflicting requirements.
PR-000-23COMP-R05 Pipe Wrinkles Comprehensive Compendia
Authors: Choquette Gary
Published: August 2023

This compendium is a selection of past PRCI research related to the formation and management of pipe with wrinkles. Metadata is provided for each resource (when available) including the length of the report, its abstract, author(s), and company that performed the research.

The process of identifying reports for this compendium involved keyword searches of all PRCI research documents (and in some cases, research by others). The list of documents identified in that keyword match was then manually reviewed for relevance. Documents that had content that was not directly relevant to the topic of this compendium, had minimal information, or duplicated information were excluded. Specifically, this study reviewed 163 documents and only selected 61 documents that were deemed relevant. Key excerpts and/or notes were taken from those documents and are included here. In many cases, the excerpt/notes are adequate such that the source document does not need to be read separately. However, there are some documents that contain much more content than can be adequately summarized herein. In those cases, the note recommends reviewing that document in its entirety.

Links to each of the reports are provided to help facilitate quick access to the related reports. A valid PRCI account is needed to access these links on the PRCI website. It is recommended that when logging onto PRCI's website, the 'keep me logged in' feature is enabled. Not all the links will be assessable to non-PRCI members.
PR-000-23COMP-R03 Pipeline Risk Management
Authors: Choquette Gary
Published: August 2023

The PRCI Technical Committees have carried out many research projects related to identifying and managing pipeline safety risks. Since not all studies sponsored by other industry groups (e.g., API, EPRG, APIA, etc.) or by individual pipeline companies are not included, this report does not represent a review of the topic in the broader industry-wide sense. Instead, it is designed to provide a guide to past work so that current PRCI members and its research contractors can identify and locate project reports that might be of use in understanding pipeline risk management.
PR-328-203803-R01 Improve ILI Sizing Accuracy
Authors: Cazenave Pablo , Jimenez Katina , Tandon Samarth , Krishnamurthy Ravi
Published: August 2023

This multi-phased PHMSA/PRCI project aims to conduct a collaborative study (pipeline operators, ILI Technology Providers (TPs), subject matter experts, and consultants) to quantitatively measure and improve the detection and sizing capabilities of current corrosion ILI systems.

A data-driven approach was used which identified problematic corrosion profiles based on the review of recent Root-Cause-Analysis reports of corrosion-related failures to design and construct an ILI corrosion test string containing features having similar profiles. All such profiles were then documented using the best possible NDE techniques.

Three participating ILI TPs proposed appropriate inspection tools based on limited knowledge of the integrity conditions in the test string.

A series of blind pull-through tests of the ILI systems were carried out, where the TPs delivered standard ILI reports for performance evaluation. The ILI TPs receive detailed feedback identifying the detection and sizing gaps. They are given a limited sample of detailed anomaly profile data to identify potential sources of detection and sizing improvement.

A second series of ILI tests are performed and the changes in detection and sizing are analyzed and quantified for each problematic corrosion profile, identifying the improvements and the remaining gaps.

The results and findings of this 3.5-year long project are presented in this Report.

This research was funded in part under the Department of Transportation, Pipeline and Hazardous Materials Safety Administration's Pipeline Safety Research and Development Program. The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the official policies, either expressed or implied, of the Pipeline and Hazardous Materials Safety Administration, or the U.S. Government.
Counternarratives as Truth-telling: Survival, Community & Racial Justice in Higher Education
Authors: Ramdeholl Dianne , Jones Jaye
Published: August 2023

Utilizing excerpts from the recently published Confronting Institutionalized Racism in Higher Education: Counternarratives for Racial Justice (Ramdeholl & Jones, 2022), the authors engage Critical Race Theory (CRT) and more specifically, counternarratives as a strategy for centering the voices and experiences of racialized faculty in Predominantly White Institutions (PWIs). Counternarratives also provide space for these faculty to interrogate their everyday lived realities and struggles, and demonstrate how they actively resist silencing and erasure through collective action.
NB: The authors capitalize Black, Asian, Brown, and Latinx and not white, when referring to racialized groups to center the collective sense of identity among BIPOC communities.

Lost & Found: 98. Permian fish from Fulwell Quarries, Sunderland
Authors: Holden Jane
Published: August 2023

Information is sought as to the type, number and location of fish from the Permian Upper Magnesian Limestone of Fulwell, Sunderland. The quarries were worked extensively during the late 19th and early 20th centuries, and yielded numerous specimens of Acentrophorus yarians and Acrolepis kirkbyi, many of which were sold and hence became parts of prestigious collections throughout the country. Preservation is usually good and easily recognisable, the fish often being a golden brown colour in a characteristic creamy yellow matrix as opposed to the more typical black Marl Slate fish in a bituminous matrix. Fossil synonyms for the above two species include Acentrophorus glaphyrus Palaeoniscus varians P. altus P. abbsii angustus? Acrolepis sedgwickii...

Representation of the Three August Ones in Lo Mi’s Lu shi
Authors: Terekhov Anthony E. E.
Published: August 2023

The focus of the present article is the notion of the Three August Ones (san huang)the legendary monarchs who allegedly ruled All-Under-Heaven in the deepest antiquity, and its representation in the treatise Lu shi (Grandiose History) by the Southern Song intellectual Luo Mi (11311189/1203). This treatise develops the idea of the three trinities of the August Ones, with most attention paid to the Middle Three August Ones (zhong san huang). The article compares the interpretation of the images of the Three August Ones recorded in Lu shi with their description from the Taoist work Jiu huang tu (Images of the Nine August Ones). The main attention is paid to several aspects: the composition of the cohort of the Middle Three August Ones, their appearance, numbers and names. The translation of the parts from the second chapter of Lu shi dedicated to the Middle Three August Ones is given in the appendix.

Published: August 2023

Pulmonary atresia is a rare congenital cardiac malformation. The newborns with this anomaly are ductus dependent to maintain a continuous and adequate pulmonary blood fl ow. As spontaneous closure of the ductus is expected after few hours or days after birth, the patency of ductus should be provided by prostaglandin E1 (PGE1) while the patient is awaiting cardiosurgical intervention. PGE1 infusion is usually applied for a short time period. However, in some circumstances, the infusion duration may extend from weeks to months. Long term PGE1 infusions may produce several adverse effects. In this report, we presented a case of newborn with pulmonary atresia who developed cortical hyperostosis secondary to prolonged use of PGE1.

Published: August 2023

Introduction: Anatomic variations of canine alveols can pose a considerable challenge to endodontic diagnosis and treatment. The purpose of this study is determining the bifid alveol and bifid root of canine tooth in dried jaws and pulled out canine roots, to deal with their clinical significance.
Materials and Methods: We examinated 100 dried human maxillary bones and 76 mandibular bones for existence of bifid alveol. Age, sex and race of these bones were unknown. In 158 pulled out canines from endodontic patients, are examinated for existence of bifid root. 98 of these canines were mandibular and the others were maxillary.
Results: In our study, we observed 2 bifid alveol in 76 dried mandible. Besides one mandibular bifid root detected in the 158 pulled out canines.
Conclusion: This unusual anatomy could lead to problems during exfoliation or extraction of canines. Clinicians should be careful during extraction of anomalous canine teeth to ensure that all roots have been retrieved. This variation could not be discovered with routine intraoral examination. But it is usually discovered with routine dental radiographs. As a result, this anomaly should kept in mind and radiographs should be taken before the extraction of canine.
Silicosis in denim sandblasters in Turkey

Published: August 2023

Silicosis is a pneumoconiosis caused by the inhalation of crystalline silica. It is the oldest occupational lung disease, but it continues to cause significant morbidity and mortality world wide due to a lack of preventive measures in the workplace. Denim sandblasting silicosis was initially identified in Turkey as a new and unexpected cause of silicosis, and it continues to be reported from other developing countries where denim sandblasting is still taking place. An aggressive form of silicosis was the most common presentation in Turkey reflecting the intense exposure to silica. Many young men have become disabled or have died due to denim sandblasting even though exposure to silica stopped, demonstrating the progressive course of this disease. Unsafe working conditions were the most important contributors in the development of this silicosis outbreak in these workers in Turkey. The aim of this review is to high light the need for occupational hygiene measures to prevent silicosis and to emphasize the importance of the occupational history

Vision can be lost after orbital infection as a result of optic nerve atrophy, central retinal artery occlusion (CRAO). We report such a case. We present a case report CRAO secondary to periorbital cellulitis. A 52-years-old male patient attended our clinic with left upper eyelid edema, hyperaemia, pain and visual loss. History revealed that he had an ocular surface trauma with cement to his left eye 7 days before. Fundus examination showed patchy filling of the branches of the central retinal artery, retinal opacification at the posterior pole and cherry red spot at the macula. His left visual acuity was declined to no perception of light. There was no clinical improvement after 7 days teatment. Orbital cellulitis did not respond to all treatment and magnetik resonance imaging demonstrated subperiosteal abscess at the posterior-superior orbital wall. We report a case of orbital cellulitis following an ocular surface trauma resulting in the rare complication of central retinal artery occlusion.

Published: August 2023

The electrochemical reduction mechanism of lodenafil carbonate in acidic medium was studied using cyclic voltammetry, square wave voltammetry and chronoamperometry (sulfuric acid 0.1 mol L-1, potential controlled at -1.2 V). The formed product characterization was carried out by FT-IR spectroscopy combined with quantum calculations of the lodenafil molecular orbitals. Over the products IR spectrum, it was possible to note the presence of absorption bands corresponding to the aldehyde, amine and ethanol groups. These results, together with those obtained by electrochemical techniques and quantum calculations, allowed us to propose that the process of reducing lodenafil is dependent on protons and occurs in four irreversible steps, the first being the amide group reduction to an aldehyde and a primary amine. Then, the aldehyde is reduced to an alcohol, with the consumption of two electrons and two protons in each of these steps. Then, there is a reduction in two processes of one electron and one proton each, one of which by a radical way. In this last process, there are two possibilities: one is the sulfone group reduction and the other is the azomethine reduction adjacent to the amine group formed in the previous step.

Numa abordagem qualitativa realizou-se o levantamento de artigos publicados em periódicos brasileiros nos últimos 11 anos. Constatou-se que vários pesquisadores escreveram a respeito do tema abordando principalmente a presença de estudantes estrangeiros, ou naturalizados que possuem língua e culturas próprias, trazendo para a escola experiências e vivências apreendidas com suas famílias. Verificou-se que com o Programa de Escolas Interculturais de Fronteiras (PEIF) criado em 2012, houve um avanço no sentido de valorizar e conhecer uma segunda língua e a preocupação com a formação dos professores que em suas salas de aula atendiam a alunos brasileiros e de dupla nacionalidade.
A cidade do outro: representações simbólicas e mercantilização da imagem em guias
Authors: Carvalho Thereza Christina Couto , Mattos Guilherme Meirelles Mesquita de
Published: August 2023

Este artigo trata da contribuição de guias turísticos na produção do imaginário de duas cidades, Lisboa e Rio de Janeiro. Intervenções urbanas de escala monumental são, com frequência, percebidas pelo olhar estrangeiro, como representação simbólica do outro. Guias de diferentes décadas e séculos, quase duzentos anos, foram consultados e servem de base ao artigo. Algumas das múltiplas visadas que as duas cidades oferecem a partir dessas representações especialmente produzidas para o olhar estrangeiro são aqui discutidas. Dois propósitos estratégicos parecem emergir dos guias selecionados para estudo. No caso de Lisboa, redimir singularidades outrora equivocadamente denegridas. No caso do Rio de Janeiro, o despertar para um mundo distinto e maior que o império português.

Objetivo: La investigación científica es un proceso fundamental en la búsqueda del conocimiento y el avance de la sociedad. En este contexto, la asesoría de tesis desempeña un papel crucial al guiar y apoyar a los estudiantes en su trayectoria hacia la creación de nuevos conocimientos. Sin embargo, en ocasiones, este proceso se ve afectado por la presencia de un fenómeno preocupante y perjudicial: el maltrato al asesorado de tesis. Por ello, el objetivo fue evaluar la percepción del maltrato a los asesorados de tesis de la carrera profesional de Educación de una universidad pública peruana.
 
Método: La investigación se desarrolló bajo un enfoque cuantitativo, un diseño no experimental y fue de tipo descriptiva – transversal. La muestra fue constituida por 209 asesorados de tesis quienes respondieron a la Escala de Maltrato al Asesorado de Tesis, instrumento con adecuados niveles de validez y confiabilidad.
 
Resultados: Según la percepción de los asesorados, el 40,2% considera que el nivel de maltrato es bajo, el 38,3% sostiene que es moderado y el 21,5% indica que es alto. Por otro lado, se estableció que el maltrato se dio principalmente por los asesores de tesis, los jurados de tesis y en menor medida, por el personal administrativo.
 
Conclusiones: De acuerdo a la percepción de los asesorados de tesis, el nivel de maltrato predominante era bajo, el cual se daba principalmente por sus asesores. Por ello, resulta necesario concientizar a las personas involucradas en el proceso de elaboración de tesis sobre el rol que realizan y adopten conductas de apertura, apoyo, diálogo y comprensión frente a los tesistas sin dejar de lado la objetividad y rigurosidad que siempre deben caracterizarlos.

O objetivo desse trabalho foi obter hidrolisados hemicelulósicos a partir dos resíduos agroindustriais com concentração de açúcares redutores necessária para obtenção desses compostos biotecnológicos sem a necessidade de concentrá-los. Foi realizada coleta dos resíduos de abacaxi (casca e coroa), laranja (bagaço), abóbora (casca e sementes), melão (casca e sementes) e maçã (casca e bagaço), seguidos de preparação para os processos de hidrólise, que consistiu na secagem e moagem dos materiais. Na hidrólise ácida dos resíduos secos e moídos fez-se a aplicação de ácido sulfúrico 2% em uma temperatura de 121°C por 15 minutos, e na hidrólise por explosão a vapor, aplicação de vapor a uma pressão de 1,8 kgf/cm² e temperatura de 130 °C por 15 minutos. Posteriormente foi efetuada a quantificação de açúcares redutores antes e depois dos processos de hidrólise pelo método de DNS e a quantificação de açúcares por HPLC. Entre os resíduos hidrolisados, observou-se que a hidrólise ácida foi mais eficiente, com uma liberação maior de glicose e xilose em resíduos de abacaxi e melão e laranja . Pode-se notar que a hidrólise ácida foi mais eficiente em relação a explosão a vapor, e apenas nesse método a arabinose foi liberada apenas da casca de abacaxi.

Present study was aimed to evaluate sperm motility and mitochondrial membrane potential (MMP) in relation to the presence of heparin binding proteins (HBPs) in semen. Semen was collected from 17 Holstein Friesian breeding bulls. Seminal plasma and sperm membrane proteins were isolated by precipitation method; HBPs were isolated using heparin-sepharose affinity chromatography. SDS-PAGE was performed and bulls were categorized into 3 groups based on presence/absence of 24 and 30 kDa HBPs. Computer-assisted semen analysis revealed that fresh ejaculates of bulls positive for 30 kDa HBP had 4.24 and 14.18% of higher total motile sperm than semen with 24 kDa and negative for HBPs. Semen with 30 and 24 kDa had 18.72 and 12.34% of higher number of sperm with progressive motility and velocity than semen devoid of HBPs. Simultaneous assessment of plasma membrane integrity (PMI) and MMP by fluorescence staining revealed that post-thaw sperm of semen with 30 kDa HBP had 6.28 and 12.79% of higher intact PMI. Further, sperm of semen with 30 kDa HBP had 4.61 and 10.50% of higher MMP, which had travelled an extra distance of 9.71 and 4.95 mm through cervical mucus than semen with 24 kDa and devoid of HBPs. The mucus penetration distance showed a strong positive correlation with high MMP, PMI, sperm motility and velocity. It is to be concluded that HBPs were able to sustain higher percentage of motile sperm with progressive motility and MMP which was depicted by more mucus penetration distance.

In the present study, molecular expression and characterization of TS14 gene of Taenia solium (Indian isolate) was carried out for sero-prevalence study of porcine cysticercosis. The complete open reading frame (ORF) of TS14 gene was amplified by RT-PCR from mRNA isolated from T. solium cysticerci (Indian isolate). The amplicon was cloned into the pET-32a(+) expression vector and used to transform Escherichia coli BL21 codon(+) cells to produce TS14 antigen. The nucleotide and deduced amino acid sequences of the TS14 were aligned against the related sequences of T. solium available in public domain for in silico analysis by DNA STAR and MEGA version 4.0 softwares. The nucleotide sequence revealed that the TS14 gene of T. solium (Indian isolate) encodes 85 amino acids and its nucleotide sequence had 98.8% to 99.5% sequence homology with that of China, Peru and Mexico isolates. A high-level expression of the recombinant protein was observed in the molecular range (Mr) of 29 kDa. The rTS14 was confirmed by its specific immunoreactivity against hyper-immune and known reference positive pig sera (8). The protein was serologically non-reactive to known cysticercus negative pig sera samples and further lacks cross-reactivity against hydatid cyst positive pig sera. The present preliminary investigation revealed the good potential of rTS14 for serodiagnosis of T. solium cysticercosis.

Trypanosoma evansi, an extracellular haemoprotozoan parasite, causes surra in a wide range of domestic and wild animals. In the present study, a diagnostic PCR assay was developed using primers targeting invariable surface glycoprotein (ISG) gene of T. evansi, which amplified a 196 bp product. The DNA was extracted from purified trypanosomes and T. evansi infected mice blood, and serially diluted ranging from 20 ng/µl to 0.002 pg/µl and from 90 ng/µl to 0.009 pg/µl, respectively. The diagnostic sensitivity of the PCR assay was 0.02 ng/µl (2×101 parasites) and 0.09 ng/µl (1×102 parasites) with purified parasite DNA and infected mice blood DNA, respectively. The PCR assay was also performed on extracted genomic DNA from 86 blood samples from the field out of which 3 animals were found positive by ISG-PCR assay. The developed ISG gene based PCR assay could be employed for sensitive detection of early infection, sub-clinical status of trypanosomosis and drug efficacy studies in animals.

Published: August 2023

First lactation records of 493 Phule Triveni cows sired by 55 bulls on production traits, viz. first lactation 300- day or less milk yield (FL300DMY), first lactation length (FLL), first dry period (FDP) and reproduction traits like age at first calving (AFC), first calving interval (FCI) and first service period (FSP) were used to compare the heritability estimates of FL300DMY under single-trait animal model (ST-AM) versus multi-trait animal models (MT-AM) in Phule Triveni cattle. Under two-trait models, the heritability estimate was found to be highest in FL300DMY-AFC combination as 0.34 ± 0.14. Under three-trait models, the heritability estimate was highest (0.33 ± 0.14) in FL300DMY- AFC- FDP combination. Under four-trait models, the highest estimate of heritability (0.53 ± 0.12) was in FL300DMY-FLL-AFC-FCI combination. Comparison of heritability estimates of FL300DMY from different models revealed that the estimates were varying from single to multiple traits in different combinations. The lowest residual variance (190566) and highest heritability (0.53 ± 0.12) of four-trait combination FL300DMY- FLL-AFC-FCI indicated that this four-trait combination should be used for selection of Phule Triveni cows.
