Published: August 2022

Background: Distal radial fractures are very common in Orthopaedic practice but still there is no unanimity about its treatment.
Objective: To evaluate the external fixator for the treatment of unstable distal radius fractures.
Methods: This prospective observational study was carried out from January 2018 to December 2019 over a period of two years. Twenty-five consecutive patients of both sexes between the ages of 18 to 60 years with closed or open unstable distal radius fractures with or without intraarticular extension admitted in the Department of Orthopaedic Surgery, 250 Bedded General Hospital, Tangail & several private hospitals in Tangail & Dhaka city were selected. Patients with diabetes mellitus or chronic renal or hepatic disorder or extra-articular fractures or volar & dorsal shear injuries (Barton fractures) were excluded from this study. All the patients were evaluated thoroughly including distal neurovascular status and any associated injuries ruled out. Patients were operated as early as possible. But 4 cases were lost to follow up. Remaining 21 patients were followed up for at least 6 months and a maximum period of 12 months.
Results: In this series mean age of the patient was 35.71±11.65 years and males (66.7%) were predominant than females (33.3%). In this series right side was involved in 13 patients (61.9%) and left side in 8 patients (38.1%). The mechanism of injury included road traffic accident 13 (61.9%), fall on slippery ground 7 (33.3%) and occupational accident 1 (4.8%). Six patients of this study (28.6%) had associated injury other than the local soft tissue injury. Most of the patients (66.7%) were operated on the day of admission, 2 patients (9.5%) were operated within 3 days and 5 patients (23.8%) were operated within 7 days. As per AO classification, majority (38.1%) injury was type C3 fracture followed by C1 (33.3%), C2 (14.3%), B1 (9.5%) and A3 (4.8%). According to functional outcome, satisfactory was 76.2% and according to anatomical outcome, satisfactory was 85.7%.
Conclusion: According to this study finding satisfactory outcome was 76.2% (functional) and 85.7% (anatomical).

Authors: Jabin Nashat , Moinuddin KM , Sultana Parveen , Rahman Md Ridwanur , Reza AM Selim
Published: August 2022

Background: Suicide is the act of intentionally taking your own life. Hanging is always suicidal unless otherwise proved. It is a from of violent asphyxial death. It produces painless death for the victims so that it is a widely practiced method of suicide. Every year, 8 lac people die for hanging. In Bangladesh hanging in one of the Commonest methods of suicide.
Objectives: The objective of this study was to find out Socio-demographic characterizes of victims, common ligature materials used by victims and post mortem findings.
Materials and method: A retrospective cross sectional study was done in Shaheed Suhrawardy Medical College mortuary during the period of July 2018 to December 2020. During this period data were collected from 1815 cases of medico legal autopsies by purposive sampling.
Results: A total of 1815 medico legal autopsies were analysed of which 818 (45.06%) were deaths due to hanging. out of these 818 cases maximum 395(48.28%) deaths due to hanging were in age group of 21-30 years. Majority of the cases 546(66.74%) were observed in female and others in male 272(33.25%). Majority 425 (51.95%) of victims had used Dopatta (Orna) as a ligature material. Cyanosis of finger tips and nail beds was the commonest 797 (97.43%) finding in cases of asphyxia death due to hanging. Conclusion: In this study all the cases of hanging were suicidal and no case of post-mortem hanging was documented. Majority of the victims were between 21-30 of age (48.28%). Twothirds of them were females. Most frequent occupation was students. More than two thirds belonged to low socio-economic condition and none of the case were from higher socio-economic condition. More than 70% victims were found inside house with locked door. In more than threefourth of the cases, the ligature material was dopatta (orna), apparently because of cost and availability. In most cases the point of suspension was ceiling fan. Complete hanging was most frequent type of hanging. Other external and internal autopsy findings were like book picture.

Published: August 2022

Background: Chronic pancreatitis being one of the most distressing medical condition, is often complicated by common bile duct obstruction, fibrosis and acute inflammation of the pancreas. Pain, weight loss and diabetes are common in these patients. Surgery is the ultimate option after medical treatment fails to solve the distress. Longitudinal Pancreatico-jejunostomy is widely practiced all over the world as the option of choice. Pancreatico-gastrostomy is also being practiced by a few surgeons in a few centers. Here we practice Longitudinal Pancreaticogastrostomy (LPG) for chronic pancreatitis patients in our setup. This study was aimed to analyze the outcomes and privileges of LPG.
Method: This prospective study was monitored and guided by the Department of Hepatobiliary and Pancreatic Surgery, Shaheed Suhrawardy Medical College Hospital, Dhaka over a period of 18 months. A total of 36 patients with chronic pancreatitis were allocated for Longitudinal Pancreatico-gastrostomy (LPG) surgery. Study tools included pain gradation, body weight, investigation profiles- serum lipase, blood sugar, USG of abdomen, CT Scan and MRCP. Duration of surgery, blood loss, hospital stay, assessment of post-operative pain relief and surgical complications were the parameters of the study. For pain relief assessment patients were divided into three categories, complete (no complaint pain), satisfactory (mild tolerable pain with normal daily activities) and unsatisfactory (moderate to severe pain requiring medication and hampered daily activities).
Results: 36 patients in the group underwent LPG. Mean age in group was 22.94 ± 3.76 years. Majority of the patients had unknown etiology. The mean duration of illness in group was 4.27 ±0.96 years. LPG was easier to perform, took less time, less blood loss and hospital stay was short with less post-operative complications. Pain relief was satisfactory with most patients showing complete pain relief. Diabetes patients got much better glycemic control after surgery. Weight gaining was also significant.
Conclusion: LPG is an easier and safer surgery which achieves good pain relief, glycemic control and nutritional improvements. Large volume studies should be done to establish its dominance against other surgical procedures.

To be true, the name of this specific pathological lesion is not widely encountered in our dayto- day surgical practice, but still, pilomatricoma or pilomatrixoma is notifiable skin neoplasm for which diagnosis can be made histopathological and only after an adequate excision. This case report is of a 23-year-old young female medical student who presented with swelling in neck, that histopathologically diagnosed as pilomatricoma. The purpose of reporting this specific case is that this pathology is rare in occurrence, but more rarely diagnosed because of lack of confirmatory pathological analysis and it is immensely essential to be kept in the differentials of all superficial skin tumors in surgical practice.

Assessment of Perinatal Clinical Characteristics, Perinatal Risk Factors, and Microbial Profile in Congenital Nasolacrimal Duct Obstruction in a Tertiary Care Center: A Descriptive Study
Authors: Natarajan Kaviyapriya , Kasturi Nirupama , Sistla Sujatha
Published: August 2022

Purpose: To assess the perinatal risk factors, clinical characteristics, and microbial profile in congenital nasolacrimal duct obstruction (CNLDO).Methods: A prospective observational study was conducted in pediatric patients of age <5 years. After a thorough clinical evaluation, the diagnosis of the CNLDO was confirmed by a Jones dye test or fluorescein dye disappearance test. A microbiological culture of lacrimal sac resurge was done with a sterile swab stick without touching the lid margins. Antibiotic susceptibility was then performed for the standard antibiotics.Results: Seventy-one eyes of 52 children were included in the study. The mean age was 3.4 months. Our research found an equal number of cases born via spontaneous vaginal delivery and Caesarean section. Nine children (17.3%) had associated systemic and ocular anomalies. The number of cultures that were positive for any growth was 19 (27%). The most common isolate was Streptococcus pneumoniae which constituted eight cases (42%), followed by Pseudomonas aeruginosa (15.8%), and Escherichia coli (10.5%). Other organisms that grew were Klebsiella pneumoniae, Staphylococcus aureus, Staphylococcus epidermidis and nonfermenting gram-negative bacilli. Gram-positive organisms were susceptible to ciprofloxacin, amoxiclav, and oxacillin, and most of them were resistant to erythromycin. In comparison, gram-negative organisms showed 62.5% resistance and 37.5% susceptibility to ciprofloxacin.Conclusions: CNLDO was more commonly unilateral, in male, preterm, and normal birth weight infants. Bilateral CNLDO was more commonly associated with coexisting ocular or systemic anomalies. Prematurity, delivery by Caesarean section, and presence of congenital anomalies were associated with a prolonged course. S. pneumoniae was the predominant isolate in our patient population.
The Role of Students’ Perception of Classroom Atmospherics on Second Language Learning Performance
Authors: Yadav Sresha , test Khomendra
Published: August 2022

Second language learning is an important area of research in the language and linguistic domain. Previous researchers have highlighted that classroom atmospherics has a significant impact on students' learning and students' performance. However, the effect of classroom atmospherics (broadly categorized under three heads---Technology, Location, and Aesthetics) on second language learning performance has not been explored with much rigor. Therefore, the present study aims to explore the classroom atmospherics influence on second language learning performance. A data sample consisting of 165 students was collected and analyzed. The study results uncover certain preconditions for second language learning, especially about classroom atmospherics. The study has high implications on language acquisitions and learning, design of classroom atmospherics, environmental psychology, anthropometrics, to name a few.
The Nexus between Financial Development and Exports Performance: A Re-Assessment with the Structural Gravity Model
Authors: Mouanda-Mouanda Gilhaime
Published: August 2022

The aim of this paper is to re-examine the relationship between financial development and international trade within the structural gravity model. Unlike the previous literature, we implement an identification strategy that considers intra-national trade flows in addition to international trade data in order to deal with the issues of perfect collinearity and the multilateral resistances terms (MRTs). Using a sample of 64 countries and two data frameworks (cross-sectional and panel) and applying the OLS/2SLS estimator and the PPMLHDFE estimator, our findings support the promoting effect of financial indicators on exports of all manufacturing goods relative to domestic trade. This performance is disproportionately higher for final goods than intermediate inputs. Importantly, this research demonstrates the existence of the heterogeneous direct impact of financial development on international trade depending on the level of economic development and across industries.
FIRMS’ PERFORMANCE AND INNOVATION: EVIDENCE FROM SMALL AND MEDIUM ENTERPRISES (SMES) IN NIGERIA
Authors: Quadri Faruq
Published: August 2022

The effect of innovations on the performance of SMEs in Nigeria was studied in this study using firm-level data from the Enterprise Survey Panel Data for the years 2007-200. Meanwhile, to investigate the relationships between innovation outcomes and firms’ performance, we used static panel data models. The Hausman test statistic, which Hausman created, was used to choose between fixed and random effects estimators. The result showed that 52.05 percent of the 1729 companies polled claimed they had developed a new or significantly improved product, and 52.54 percent said they had developed a new or significantly better process. In the last three years, however, less than half of the organizations (41.87 percent) had undergone organizational transformation. Finally, we noticed that there was a transition from one form of innovation to another throughout time. Furthermore, there was a significant and favorable link between innovation outcomes and R&D spending, as well as employee training. The studies also demonstrated a positive and statistically significant link between firm’s productivity and innovation outcomes. As a result, we recommend that the government encourage strategic coordination of both human and non-human capital in SMEs, such as R&D personnel, FDI inflows, technology, and information. Increased access to funds for research and innovation in formal institutional contexts, as well as policy packages that are highly supportive of innovation
General Solution of Thick Plates on Winkler-Pasternak Foundation Using Orthogonal Polynomial Displacement Functions
Authors: Uzodinma Franklin , Onodagu P. Dinwoke  , Aginam C. Henry  , Ubani U. Obinna
Published: August 2022

A solution for thick plates on Winkler-Pasternak foundation using characteristic orthogonal polynomials (COPs) displacement functions was presented in this study. A shear deformation function was developed from Soldatos’ (1992) trigonometric function and the Ritz energy approach was used to determine the total potential energy of the thick plate on elastic foundation. This method presents a simple and efficient method where only definite integration is required to obtain solutions. Results for non-dimensional in-plane and out-of-plane displacements for simply supported (SSSS) thick plates were presented and was observed to converge with that of other third-order shear deformation theories (TSDT) available in literature. From the study, it was observed that the in-plane and out-of-plane displacements reduced generally as the foundation modulus of the soil increased and decreases as the span-depth ratio increased for each aspect ratio. Both the Winkler and Pasternak foundation parameters influenced the results obtained as the foundation modulus is dependent on these parameters.

Published: August 2022

Objective: To estimate the consumption and quantity of unaltered antiretrivirals (ARV) eliminated into the environment and to carry out a literature research on aquatic ecotoxicological studies of ARV used in Brazil. Methodology: We requested from one of the ARV dispensing units in the city of Belo-Horizonte (BH) the amount of ARV dispensed in the years 2018-2019-2020. Considering the amount dispensed in 2020, the daily dose, and the elimination rate, the amount of drug in unchanged form in the environment was estimated. For entire municipality of BH and Brazil, we used epidemiological data were used regarding individuals using antiretroviral therapy (ART) in 2020, the proportion of people living with HIV using the main ART regimen, following the same estimation methodology used previously. Structured and individual searches were carried out for each ARV used in Brazil, relating it to ecotoxicology, through Google Scholar, National Center for Biotechnology Information and Scifinder, in addition to the use of the fass.se platform. Results: Four articles presented results of acute or chronic toxicity in ecotoxicological models involving ARV. Dolutegravir and efavirenz were found to be highly toxic in ecotoxicological models. In 2020, approximately 2,167kg of ARVs in unchanged form were released into the environment in BH. In Brazil it was 112,274kg. Conclusion: It is urgent to quantify the main ARV in water bodies. With these data together with ecotoxicological data it will be possible to establish risk criteria for possible measures to control or mitigate these contaminants in the environment, especially actions to improve wastewater/water treatment.

This paper aims to review the current situation on how Photography has completely changed the way we see and engage with the world. The shift from analogue to digital Photography significantly impacted how an analogue photographer perceives the photo process.  In the age of these diverse prosumers, the distinction between artists, media professionals, and amateurs may still denote varying degrees of craftsmanship. However, it no longer indicates the inherent technical or aesthetic quality of the results or the likely size of an audience. The impacts give the impression that the aesthetics and attention of Photography provided revolution change in the society of arts and Photography. From this perspective, Photography has ﬁrst been chemical, then optical and now computational. The changing identities of Photography herein are not simply ontological transformations but also errant modes of perceiving the medium.

Published: August 2022

Chinese ceramic art in the Qing Dynasty, it has won a lot of praise for its unique shape and exquisite, wonderful decoration form. The ceramic revolving core bottle（CRCB） has an obvious unique decorative form. From the perspective of formal analysis, through the concrete analysis of the decoration form of the CRCB, this paper puts forward three characteristics of the CRCB in the Qing Dynasty: rich color expression, three-dimensional space expression, flow and continuous picture structure. It is believed that the CRCB is a unique decorative form based on the ceramic decoration form of the past dynasties in China, which integrates the formal elements in Chinese classical gardens and Chinese paintings. The author holds that the performance of this form reflects the authority of the ruler, the popularity of Chinese classical gardens in the Qing Dynasty, and the revival and re-creation of Chinese classical painting forms in the Qing Dynasty, which is the witness of the exchange between Chinese ceramic art and Chinese traditional culture.

Published: August 2022

The Malaysian film industry has entered the digital industry when all production and national broadcasting companies shifted to digital equipment and facilities. This raises the issue on how to preserve local films from here on out regardless of the video recording method. While there are some government institutions tasked with digitising and preserving films (negatives) in Malaysia, little is known about the procedure, protocol, and priority of this development. Through in-depth interviews with key personnel from National Film Development Corporation Malaysia (FINAS) and Arkib Negara, the study investigates the fate of Malaysian films especially the ones produced using film format. Finding indicates that while there are intensive work conducted by both repository institutions to digitise archived films, priorities are given to film documentaries and government-related news coverage thus setting aside the jewels of Malaysian historical and classical feature films towards uncertain future.

This study aims to determine how the process of implementing the Kalo sara-based village development planning model is and its effect on increasing community participation in village development in Lambudoni Village, Andowia District, North Konawe Regency. Informants were selected with purposive sampling. The selected informants included: village head, village secretary, head or BPD member, traditional leaders and several local residents. Using a qualitative descriptive method, the data was collected through observation, interviews and documentation. Data analysis was carried out using a qualitative descriptive method. The results show that the process of implementing Kalo sara-based village development planning started with the hamlet level for them to discuss what the main problems are in the area and the results are formulated in the form of a village development program. Thereafter, the results of the program formulation are then brought to the sub-district level to be discussed by the sub-district government along with residents and village officials, and the results are formulated into 2 (two) program priorities: main priority; and (2) supporting priority development programs. Kalo sara influences very significantly the level of community participation in village development because it contains the values ​​of samaturu (mutual cooperation); medulu mepokoso (unity and integrity); ate pute penao moroha (holiness and justice); and morini mbu'umbudi monapa mbu'undawaro (prosperity and welfare) that become the spirit or motivation for the community to keep participating actively in each of village development plans.

Mepe kasur traditional ritual is a still sustainable local wisdom coming from Banyuwangi, where people dry the black and red mattresses together in front of the house. This study aims to analyze the implementation procedure and the social construction through internalization, objectification, and externalization processes and symbolic interaction contained in the Mepe kasur traditional ritual. This study uses a qualitative approach with interview and observation being data collection methods. This study yielded three findings. Firstly, the Mepe kasur traditional ritual consisted of 1) the mattress was dried in the sun from morning until noon; 2) the mattress was swept and beat using a woven stick until the dust came out; 3) past noon, the mattress was put into the bed at home, 4) people went to do pilgrimage to the tomb of the great-grandfather Cili; 5) tumpeng sewu. Secondly, based on the social construction, the Mepe kasur traditional ritual has entered the processes of internalization, objectification, and externalization. Thirdly, in symbolic interaction, the Mepe kasur traditional ritual is intended to maintain the continuity of a family, where the mattress is a place for taking a rest and discussing to married couples.

Karo Traditional Ceremony is one of the traditional ceremonies symbolized by the origin of human birth, so that the Karo traditional ceremony is legally obligatory to Tengger Tribe. The objective of study is to analyze the processes of externalization, objectivation, and internalization in the social construction of traditional Karo ceremony Tengger tribe and the meaning of symbols in the Karo traditional ceremony in Ngadisari Village, Probolinggo Regency. This research used a descriptive qualitative method, with a case study approach. Informants of study were the village apparatuses and the heads of  Tengger tribal families in Ngadisari village, Probolinggo Regency. Data collection techniques used were interview, observation, and documentation. The results of study indicated that Karo traditional ceremony plays an important role in establishing and maintaining social relations. Social construction in the implementation of Karo traditional ceremony takes place in three processes. It started with the externalization stage, in which parents undertake a process of influencing their descendants. Next is the objectivation stage, in which the community's contribution can be seen from the process of organizing Karo traditional ceremony. The last stage is internalization, in which the Tenggerese people begin to believe in and preserve Karo traditional ceremonial ritual. In a series of processions the Karo Traditional ceremony has the meaning of symbols in a series of events that make the Tengger people tolerant, and obey values ​​and norms applying. The implication of research is that Karo traditional ceremony represents public awareness as indigenous people and can be known widely, especially to the younger generation, so that it can be preserved.
Culture-led urban regeneration and local expectations of urban void renewal in eastern Lisbon
Authors: Martins Joao Carlos
Published: August 2022

This article will analyze the ongoing culture-led regeneration processes of abandoned, informal and vacant areas, often considered by residents, local associations, and public officials to be urban voids. Our territorial framework is in Marvila, a semi-peripheral riverside area in Lisbon, strongly affected by informal activities, high levels of youth unemployment, an elderly population, and the existence of urban spaces with non-planned uses, seen as undesirable by the local ecosystem of stakeholders and particularly by residents. Our analysis will be centered around a social and spatial understanding of Lisbon’s municipal urban policy (funded by the 3.5.6. program of the European Union on Cultural Heritage), which has supported the reoccupation of some these so-called urban voids. We will focus on the use of a Pilot Project methodology, its exploratory and prototype nature, the local bureaucratic planning system, and the soft Planning techniques implemented as new ways of addressing long-term decayed and informal urban spaces. We will examine the regeneration results of two EU-H2020 funded pilot projects, under the ROCK project, which supports this research. The first pilot project “Loja Com Vida” (“store with life” or “store invites”), supports the municipal objective of creating a new urban centrality in Marvila, encouraging a diversification of its users, operationalizing the reuse of municipal ground floor spaces. The second project, “Jardim para Todos” (‘Garden for all’), corroborates a municipal urban policy on environmental sustainability goals, promoting, with the help of local agents, a learning and sharing process centered around green knowledge and the creation of a future agriculture hub and leisure area. The acknowledgment of these pilot project results will constitute an interesting case study for other urban areas with similar conditions, incorporating a better understanding of participative urban regeneration processes, outside the traditional and formal planning perspectives and achievements.
Transformative Heritage
Authors: Efrat Liron , Graziosi Casimiro Giovanna
Published: August 2022

In this paper, we analyze some of the platforms and technologies that influence the manner in which we interact and experience historical sites and heritage. Acknowledging that history is a constructed narration of the past, this paper demonstrates how contemporary technologies have agency in reconstructing histories in the present via digital platforms. By comparing online platforms for digital heritage production like Google Heritage with Augmented Reality (AR) and Mixed Reality (MR) platforms, we demonstrate how digital heritage may undergo a process recontextualization or decontextualization from its originating settings.

We also show that digital heritage’s reconstruction of history is done through the act of remediation: by turning actual remnants of the past into digital models or by replacing such remnants with virtual representation that are globally accessible, something new is created and alternative stories can be told. Within that, we consider some of the ethical issues that are raised by the migration of historical narratives into digital platforms, as we point towards a growing tendency in which history and its production can be subjected to major data companies.
Transforming Photographs into a Digital Catalogue
Authors: Gąsior Mariusz
Published: August 2022

In this article I focus on three aspects of the digitisation of photographic collections which I have had the opportunity to deal with professionally in two museums, in the UK and Poland.  In 2014, the Imperial War Museum in London (IMW) implemented an online project of the portal/monument, Lives of the First World War, commemorating all citizens of the British Commonwealth who took part in the First World War (WWI), both in uniform and in civil services. Users registered on the portal could attach documents, photographs, reports to each commemorated soldier-keyword, thus expanding the database. One of the key elements of the project was a collection of portrait photographs bearing the title Bond of Sacrifice. These comprised over 16,000 photographs of soldiers of the British Commonwealth, handed over to the Museum by their families in the years 1917–1919. After nearly a hundred years, the Museum decided to comprehensively develop, digitize, and make the collection available in the form of an online catalogue. In the meantime, the Museum digitised a huge collection of WWI photographs, the so-called Q Series (ca. 115,000), the most important part of which was British official photography. By 2016, the entire collection was scanned and made available in an external catalogue of the Museum on the basis of a non-commercial license.  Since then, the photographs have taken on a life of their own: they are used in academic works, press articles, TV productions, and in social medias. The second project includes numerous photographs of the Polish Armed Forces. This phenomenon is dealt with in the second part of this paper, which discusses the online photographic collection of the Silesian Museum in Katowice. The third and final part of this article is devoted to the impact of digitization and on-line accessibility on the making of temporary exhibitions. This is explained using the example of the author’s last exhibition at the museum about women in industry; based entirely on digital reproductions of photographs from the collections of many museums from Europe and the U.S., amongst others the US National Archives and the IWM. This is due to the fact that the author selected the entire material with the use of online catalogues of these very institutions.
Multimedia Historical Parks and the Heritage-based “Regime of Truth” in Russia
Authors: Zabalueva Olga
Published: August 2022

This article focuses on the 2013–2016 exhibitions in Moscow Manege which were later transformed into a network of entertainment centres (“historical parks”) Russia––my (hi)story. The exhibitions are built on multimedia technologies and include no authentic artefacts/museum objects. There is a growing network of such centres all over Russia, all organized in a similar manner, appealing to the visitor’s emotions and creating a relation of affect through the unravelling of a nationalistic historical narrative. Claimed to present “the objective picture of the Russian history” the exhibitions are following the recent developments in Russian cultural policies and history curricula. By analysing narratives presented at the “historical park” exhibitions, in policy documents and in media, this article follows the changes in public attitude towards history, which heritage is perceived as ‘difficult’ and ‘contested’ and how the digital representations influence these perceptions. Based on this analysis I argue that the reduction of the museum mechanism to only digital and multimedia form can bring along very serious issues in different political contexts. Russian historical parks enterprise, which combines the methods of fostering patriotism by the means of historical narrative templates both from the 19th and the 20th centuries, enhanced with the 21st-century technology in a form of “multimedia museums,” is only one of such examples.

Published: August 2022

Many supplemental Se-dependent metabolic effects are mediated through the function of selenoproteins. The full complement and relative abundance of selenoproteins expressed by highly metabolic cattle tissues have not been characterized in cattle. The complement and number of selenoprotein mRNA transcripts expressed by the pituitary and liver of healthy growing beef steers (n = 7 to 8) was characterized using NanoString methodology (Study 1). Of the 25 known bovine selenoproteins, 24 (all but SELENOH) were expressed by the pituitary and 23 (all but SELENOH and SELENOV) by the liver. Transcript abundance ranged (P ≤ 0.05) over 5 orders of magnitude in the pituitary (> 10,000 for GPX3, < 10 for DIO1 and GPX2) and liver (> 35,000 for SELENOP, < 10 for DIO2). Also unknown is the sensitivity of the selenoprotein transcriptome to the form of supplemental Se. The effect of form of supplemental Se on the relative content of selenoprotein mRNA species in the pituitary and liver of steers grazing a Se-deficient (0.07 ppm Se) tall fescue pasture and consuming 85 g/d of a basal vitamin-mineral mix that contained 35 ppm Se as either ISe (n = 6), organically-bound Se (SELPLEX; OSe, n = 7 to 8), or a 1:1 blend of ISe and OSe (MIX, n = 7 to 8) was determined by RT-PCR after sequence-validating the 25 bovine selenoprotein cDNA products (Study 2). In the pituitary, Se form affected (P < 0.05) the relative content of 9 selenoprotein mRNAs and 2 selenoprotein P receptor mRNAs in a manner consistent with a greater capacity to manage against oxidative damage, maintain cellular redox balance, and have a better control of protein-folding in the pituitaries of OSe and MIX versus ISe steers. In the liver, expression of 5 selenoprotein mRNA was affected (P ≤ 0.05) in a manner consistent with MIX steers having greater redox signaling capacity and capacity to manage oxidative damage than ISe steers. We conclude that inclusion of 3 mg Se/d as OSe or MIX versus ISe, forms of supplemental Se in vitamin-mineral mixes alters the selenoprotein transcriptome in a beneficial manner in both the pituitary and liver of growing steers consuming toxic endophyte-infected tall fescue.

Published: August 2022

When the human brain learns multiple related or continuous tasks, it will produce knowledge sharing and transfer. Thus, fast and effective task learning can be realized. This idea leads to multi-task learning. The key of multi-task learning is to find the correlation between tasks and establish a fast and effective model based on these relationship information. This paper proposes a multi-task learning framework based on stochastic configuration networks. It organically combines the idea of the classical parameter sharing multi-task learning with that of constraint sharing configuration in stochastic configuration networks. Moreover, it provides an efficient multi-kernel function selection mechanism. The convergence of the proposed algorithm is proved theoretically. The experiment results on one simulation data set and four real life data sets verify the effectiveness of the proposed algorithm.

Prosthetic implants of expanded polytetrafluoroethylene (ePTFE) in the cardiovascular system have a high failure rate over the long term because of thrombosis and intimal hyperplasia. Although multiple surface modification methods have been applied to improve the anti-thrombotic and in situ endothelialization abilities of ePTFE, none have delivered outstanding results in vivo. Our previous study combined heparin/collagen multilayers and REDV peptides to modify ePTFE, and the in-vitro results showed that modification ePTFE with heparin/collagen-REDV can promote the cytocompatibility and antiplatelet property. This study illustrated the physical change, selective endothelial cells capture ability, and in vivo performance in further. The physical test demonstrated that this modification improved the hydrophilicity, flexibility and strength of ePTFE. A competition experiment of co-cultured endothelial cells and vascular smooth muscle cells verified that the heparin/collagen-REDV modification had high specificity for endothelial cell capture. A rabbit animal model was constructed to evaluate the in vivo performance of modified ePTFE implanted in the right ventricular outflow tract. The results showed that heparin/collagen-REDV modification was safe, promoted endothelialization, and successfully achieved regional anti-thrombosis without influencing body-wide coagulation function. The pathologic manifestations and mRNA expression pattern in tissues in contact with modified ePTFE indicated that this modification method may reduce M2-type macrophage infiltration and the expression of genes related to immune and inflammatory responses. The heparin/collagen-REDV modification may lower the incidence of complications related to ePTFE implantation and has good prospects for clinical use.

The COVID-19 pandemic emphasized the importance of rapid, portable, and on-site testing technologies necessary for resource-limited settings for effective testing and screening to reduce spreading of the infection. Realizing this, we developed a fluorescence-based point-of-care (fPOC) detection system with real-time reverse transcriptase loop-mediated isothermal amplification for rapid and quantitative detection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. The system is built based on the Arduino platform compatible with commercially available open-source hardware–software and off-the-shelf electronic components. The fPOC system comprises of three main components: 1) an instrument with integrated heaters, 2) optical detection components, and 3) an injection-molded polymeric cartridge. The system was tested and experimentally proved to be able to use for fast detection of the SARS-CoV-2 virus in real-time in less than 30 min. Preliminary results of testing the performance of the fPOC revealed that the fPOC could detect the SARS-CoV-2 virus at a limit of detection (LOD50%) at two to three copies/microliter (15.36 copies/reaction), which was comparable to reactions run on a standard commercial thermocycler. The performance of the fPOC was evaluated with 12 SARS-CoV-2 clinical throat swab samples that included seven positive and five negative samples, as confirmed by reverse transcription–polymerase chain reaction. The fPOC showed 100% agreement with the commercial thermocycler. This simple design of the fPOC system demonstrates the potential to greatly enhance the practical applicability to develop a totally integrated point-of-care system for rapid on-site screening of the SARS-CoV-2 virus in the management of the pandemic.

In vitro electrogenic cells monitoring is an important objective in several scientific and technological fields, such as electrophysiology, pharmacology and brain machine interfaces, and can represent an interesting opportunity in other translational medicine applications. One of the key aspects of cellular cultures is the complexity of their behavior, due to the different kinds of bio-related signals, both chemical and electrical, that characterize these systems. In order to fully understand and exploit this extraordinary complexity, specific devices and tools are needed. However, at the moment this important scientific field is characterized by the lack of easy-to-use, low-cost devices for the sensing of multiple cellular parameters. To the aim of providing a simple and integrated approach for the study of in vitro electrogenic cultures, we present here a new solution for the monitoring of both the electrical and the metabolic cellular activity. In particular, we show here how a particular device called Micro Organic Charge Modulated Array (MOA) can be conveniently engineered and then used to simultaneously record the complete cell activity using the same device architecture. The system has been tested using primary cardiac rat myocytes and allowed to detect the metabolic and electrical variations thar occur upon the administration of different drugs. This first example could lay the basis for the development of a new generation of multi-sensing tools that can help to efficiently probe the multifaceted in vitro environment.

Hyperbranched ethylene oligomers and polar functionalized co-oligomers synthesized via ethylene chain walking (co) oligomerization is a very attractive strategy. In this study, a series of dibenzhydryl iminopyridyl ligands with benzocycloalkyl and naphthyl moieties and the corresponding Ni(II) and Pd(II) complexes were synthesized and characterized. The Ni(II) complexes were highly effective in ethylene oligomerization and ethylene oligomers with hyperbranched microstructures were generated from this system. The corresponding Pd(II) complexes showed moderate oligomerization activities in ethylene oligomerization and hyperbranched ethylene oligomers were also yielded from the system. More significantly, the Pd(II) complexes can also effectively promote the co-oligomerization of ethylene with methyl acrylate (MA) to obtain hyperbranched polar functionalized ethylene-MA co-oligomers. The reaction temperature, catalyst ligand structure and metal type all have significant effects on ethylene (co) oligomerization with respect to catalytic activity, molecular weight and topology of the oligomers.

Staphylococcus aureus nasal colonization is a risk factor for infection. A large proportion of the population are identified as potential S. aureus carriers yet we only partially understand the repertoire of genetic factors that promote long-term nasal colonization. Here we present a murine model of nasopharyngeal colonization that requires a low S. aureus inoculum and is amenable to experimental evolution approaches. We used this model to experimentally evolve S. aureus using successive passages in the nasopharynx to identify those genetic loci under selection. After 3 cycles of colonization, mutations were identified in mannitol, sorbitol, arginine, nitrite and lactate metabolism genes promoting key pathways in nasal colonization. Stress responses were identified as being under selective pressure, with mutations in DNA repair genes including dnaJ and recF and key stress response genes clpL, rpoB and ahpF. Peptidoglycan synthesis pathway genes also revealed mutations indicating potential selection for alteration of the cell surface. The murine model used here is versatile to question colonization, persistence and evolution studies.

We studied the human pathogen Staphylococcus aureus in our search to determine factors that contribute to its ability to live in the human nose and throat. The anterior nares and nasopharynx are considered primary habitats but we do not understand how the pathogen adapts as it moves from one person to the next. We first determined sustained survival of the pathogen over multiple days in the nasopharynx that might act as a good model for human persistence due to the low numbers of bacteria needed for it to establish. By using successive rounds of colonization of the nasopharynx across different mice we revealed that multiple genetic changes in the S. aureus occurred. These changes were found in genes associated with the cell surface and metabolism and might indicate adaptation to the niche. One gene showed an accumulation of multiple mutations supporting a key contribution in adaptation but the role of the protein it encodes is not yet known. The contribution of these genes and genetic changes are unclear but indicate an area for future research to better understand how this common human pathogen is so successful at human colonization and survival.
