Desk and Derrick: The Women's Petroleum Industry Club That Envisioned Oil's Technocratic Future
Authors: Stanford-McIntyre Sarah
Published: January 2023

This article uncovers the hidden history of Desk and Derrick, a female-only petroleum industry employees’ club, to emphasize the importance of clerical work and support staff to oil industry development. In doing so, it demonstrates that despite the oil industry's mythology of individual inventors and lucky wildcatters, oil was remarkably similar to other large-scale scientific and engineering enterprises during the middle decades of the twentieth century. Throughout the 1950s and 1960s, oil's white-collar and administrative jobs expanded rapidly. And in this industry as in others, women were fundamental to oil industry technological development and labor conflicts. Desk and Derrick's was a haven for working women, providing community, training, and leadership opportunities in an industry deeply hostile to female employees. The club provided numerous outreach and educational campaigns included seminars, workshops, fieldtrips, and conventions. These events showcased female competence and technical knowledge, clashing with union derision and corporate dismissal. The club's vocal emphasis on scientific education and credentialization represented a bid for female inclusion within an increasingly technically complex professional world. However, entrenched workplace sexism and union hostility to changing labor structures limited member opportunities. Ultimately, Desk and Derrick's middle-class aspirations allied the club with industry rebranding efforts and helped support industry automation and union-busting. Desk and Derrick valorized industry engineers and scientific professionals, spreading narratives of prosperity through technology that coincided with industry-wide efforts to repair oil companies’ reputations as greedy, wasteful, and exploitative. In turn, midcentury oil companies promoted Desk and Derrick as a convenient, grassroots way to spread their message.
The Ghost and the Censor
Authors: Ng Emily
Published: January 2023

The history of modern China has been filled with loss in many senses. From certain angles of vision, loss, remembrance, and forgetting orbit around figures of political repression in the People's Republic of China (PRC), particularly that of censorship. These approaches posit a link between the Chinese state, national public amnesia, and international transparency that may occlude other configurations of knowing, speaking, and mourning—those of public secrecy, for instance, including stagings of the unspeakable through aesthetic and literary forms. This essay explores such configurations through Mo Yan's Life and Death Are Wearing Me Out (2008). In the novel, narrated largely by the reincarnated specter of an executed landlord, desire and loss travel between historical, carnal, and cosmic registers while operations of violence, politics, and memory both evoke and depart from common liberalist accounts of the PRC. On a world stage of global reading communities, the tethering of the village ghost to coordinates of apparently knowable historical time pairs with the author's ambiguous position vis-à-vis the formal sign of unknowability—censorship. The text, the (partially) censored author, and their circulations together point to productions of loss in parallax, at once hosting and abstracting loss.

Published: January 2023

The heat shock (HS) response is crucial for cell survival in harmful environments. Nuclear lamin A/C, encoded by the LMNA gene, contributes towards altered gene expression during HS, but the underlying mechanisms are poorly understood. Here, we show that upon HS, lamin A/C was reversibly phosphorylated at serine 22 in concert with HSF1 activation in human cells, mouse cells and Drosophila melanogaster in vivo. Consequently, the phosphorylation facilitated nucleoplasmic localization of lamin A/C and nuclear sphericity in response to HS. Interestingly, lamin A/C knock-out cells showed deformed nuclei after HS and were rescued by ectopic expression of wild-type lamin A, but not by a phosphomimetic (S22D) lamin A mutant. Furthermore, HS triggered concurrent downregulation of lamina-associated protein 2α (Lap2α, encoded by TMPO) in wild-type lamin A/C-expressing cells, but a similar response was perturbed in lamin A/C knock-out cells and in LMNA mutant patient fibroblasts, which showed impaired cell cycle arrest under HS and compromised survival at recovery. Taken together, our results suggest that the altered phosphorylation stoichiometry of lamin A/C provides an evolutionarily conserved mechanism to regulate lamina structure and serve nuclear adaptation and cell survival during HS.
CCDC86 is a novel Ki-67-interacting protein important for cell division

Published: January 2023

The chromosome periphery is a network of proteins and RNAs that coats the outer surface of mitotic chromosomes. Despite the identification of new components, the functions of this complex compartment are poorly characterised. In this study, we identified a novel chromosome periphery-associated protein, CCDC86 (also known as cyclon). Using a combination of RNA interference, microscopy and biochemistry, we studied the functions of CCDC86 in mitosis. CCDC86 depletion resulted in partial disorganisation of the chromosome periphery with alterations in the localisation of Ki-67 (also known as MKI67) and nucleolin (NCL), and the formation of abnormal cytoplasmic aggregates. Furthermore, CCDC86-depleted cells displayed errors in chromosome alignment, altered spindle length and increased apoptosis. These results suggest that, within the chromosome periphery, different subcomplexes that include CCDC86, nucleolin and B23 (nucleophosmin or NPM1) are required for mitotic spindle regulation and correct kinetochore–microtubule attachments, thus contributing to chromosome segregation in mitosis. Moreover, we identified CCDC86 as a MYCN-regulated gene, the expression levels of which represent a powerful marker for prognostic outcomes in neuroblastoma.
Diacylglycerol at the inner nuclear membrane fuels nuclear envelope expansion in closed mitosis
Authors: Foo Sherman , Cazenave-Gassiot Amaury , Wenk Markus R. , Oliferenko Snezhana
Published: January 2023

Nuclear envelope (NE) expansion must be controlled to maintain nuclear shape and function. The nuclear membrane expands massively during closed mitosis, enabling chromosome segregation within an intact NE. Phosphatidic acid (PA) and diacylglycerol (DG) can both serve as biosynthetic precursors for membrane lipid synthesis. How they are regulated in time and space and what the implications are of changes in their flux for mitotic fidelity are largely unknown. Using genetically encoded PA and DG probes, we show that DG is depleted from the inner nuclear membrane during mitosis in the fission yeast Schizosaccharomyces pombe, but PA does not accumulate, indicating that it is rerouted to membrane synthesis. We demonstrate that DG-to-PA conversion catalyzed by the diacylglycerol kinase Dgk1 (also known as Ptp4) and direct glycerophospholipid synthesis from DG by diacylglycerol cholinephosphotransferase/ethanolaminephosphotransferase Ept1 reinforce NE expansion. We conclude that DG consumption through both the de novo pathway and the Kennedy pathway fuels a spike in glycerophospholipid biosynthesis, controlling NE expansion and, ultimately, mitotic fidelity.
Hoverfly (Eristalis tenax) pursuit of artificial targets

Published: January 2023

The ability to visualize small moving objects is vital for the survival of many animals, as these could represent predators or prey. For example, predatory insects, including dragonflies, robber flies and killer flies, perform elegant, high-speed pursuits of both biological and artificial targets. Many non-predatory insects, including male hoverflies and blowflies, also pursue targets during territorial or courtship interactions. To date, most hoverfly pursuits have been studied outdoors. To investigate hoverfly (Eristalis tenax) pursuits under more controlled settings, we constructed an indoor arena that was large enough to encourage naturalistic behavior. We presented artificial beads of different sizes, moving at different speeds, and filmed pursuits with two cameras, allowing subsequent 3D reconstruction of the hoverfly and bead position as a function of time. We show that male E. tenax hoverflies are unlikely to use strict heuristic rules based on angular size or speed to determine when to start pursuit, at least in our indoor setting. We found that hoverflies pursued faster beads when the trajectory involved flying downwards towards the bead. Furthermore, we show that target pursuit behavior can be broken down into two stages. In the first stage, the hoverfly attempts to rapidly decreases the distance to the target by intercepting it at high speed. During the second stage, the hoverfly's forward speed is correlated with the speed of the bead, so that the hoverfly remains close, but without catching it. This may be similar to dragonfly shadowing behavior, previously coined ‘motion camouflage’.

Published: January 2023

Objectives:

This study aimed to determine the three-dimensional (3D) correlation between maxillomandibular complex parameters and pharyngeal airway dimensions in different sagittal and vertical malocclusions.

Methods:

This retrospective cross-sectional study included the CBCT scans of 368 patients with a mean age of 23.81 ± 3.01 years. The patients were classified into three groups (skeletal Class I, II, and III). Each class group was divided into three subgroups based on vertical growth patterns (hypo-, normo-, and hyperdivergent). The maxillomandibular complex was evaluated in the three planes using 16 skeletal measurements. Naso-, oro-, hypo-, and total pharyngeal airway spaces were assessed in terms of width, volume, surface area, and minimum constricted area (MCA). Two-way ANOVA followed by the Bonferroni post-hoc test were used.

Results:

The nasopharyngeal airway space was significantly lowest regarding sagittal and lateral widths in the skeletal Class III patients, the lowest volume and surface area were in hyperdivergent patients, and MCA was the highest in Class II and hypodivergent patients. The oro- and hypopharyngeal sagittal width, volume, surface area, and MCA were the lowest in the hyperdivergent patients, and oropharyngeal lateral width and hypopharyngeal sagittal width were the highest in skeletal Class III. The total pharyngeal volume, surface area, and MCA were the lowest in the hyperdivergent patients, and skeletal Class II patients had the lowest MCA.

Conclusions:

The pharyngeal airway dimensions differ with various sagittal and vertical malocclusions. These differences could apply to diagnosis, treatment planning, and possible changes following orthodontic/orthopedic or surgical treatment.
Parotid gland evaluation of menopausal women with xerostomia using the iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL-IQ) method of MRI: a pilot study
Authors: Jeon Kug Jin , Park Younjung , Jeong Hui , Lee Chena , Choi Yoon Joo , Han Sang-Sun
Published: January 2023

Objectives:

This study aimed to analyze the quantitative fat fraction (FF) of the parotid gland in menopausal females with xerostomia using the iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL-IQ) method.

Methods:

A total 138 parotid glands of 69 menopausal females were enrolled in our study and participants were divided into normal group and xerostomia group. The xerostomia group was divided into those with or without Sjögren’s syndrome. Participants underwent IDEAL-IQ sequences of MRI and the stimulated salivary flow test (s-SFR). The unpaired t-test was used to compare the FFs between the normal and xerostomia groups and between the subgroups with and without Sjögren’s syndrome. The correlation between FF and s-SFR was analyzed by Pearson’s correlation.

Results:

Excellent intra- and interobserver agreement during the measurement of FFs by IDEAL-IQ method (ICC>0.99, respectively). FF value in the xerostomia group was statistically significantly higher than the value in the normal group (p < 0.05). Within the xerostomia group, the average FF value of females with Sjögren’s syndrome was higher than that of females without Sjögren’s syndrome. However, the difference was not statistically significant (p > 0.05). Within the xerostomia group, FF value correlated negatively with s-SFR (p < 0.05).

Conclusions:

The FF of the parotid gland was higher in the xerostomia group than in the normal group and FF value and s-SFR showed a negative correlation. Analyses of the FF using IDEAL-IQ in menopausal females can be helpful for the quantitative diagnosis of xerostomia.
Targeting splicing factors for cancer therapy
Authors: Bashari Ariel , Siegfried Zahava , Karni Rotem
Published: January 2023

Alternative splicing (AS) of mRNAs is an essential regulatory mechanism in eukaryotic gene expression. AS misregulation, caused by either dysregulation or mutation of splicing factors, has been shown to be involved in cancer development and progression, making splicing factors suitable targets for cancer therapy. In recent years, various types of pharmacological modulators, such as small molecules and oligonucleotides, targeting distinct components of the splicing machinery, have been under development to treat multiple disorders. Although these approaches have promise, targeting the core spliceosome components disrupts the early stages of spliceosome assembly and can lead to nonspecific and toxic effects. New research directions have been focused on targeting specific splicing factors for a more precise effect. In this Perspective, we will highlight several approaches for targeting splicing factors and their functions and suggest ways to improve their specificity.
Clinical characteristics of cerebral vascular dementia and early diagnostic value of cranial nuclear magnetic resonance
Authors: Zhou Wenxing , Li Lianxia , Lang Yan , Jiang Hongxin
Published: January 2023

Objective: This study aimed to observe the diagnostic value of cranial magnetic resonance imaging (MRI) in patients with vascular dementia induced by ischemic stroke.

Methods: The experiment was designed according to the randomized control principle. Two hundred and eighty patients with ischemic stroke who were admitted to Gucheng County Hospital between June 2019 and June 2021 were selected as research subjects. Patients without vascular dementia after stroke were included in the control group, and patients with vascular dementia after stroke were included in the observation group. The cranial MRI was performed in both groups.

Results: Proportions of patients with large and moderate infarct lesions in brain tissues were significantly higher in the observation group than the control group. The data variation of relevant MRI detection indicators of the observation group was more obvious than that of the control group (P<0.05). The mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) scores of the observation group were lower than those of the control group (P<0.05), but the HIS score was higher (P>0.05). Patients with changes in brain morphology were more in the observation group than the control group (P<0.05).

Conclusion: Patients with vascular dementia induced by ischemic stroke are characterized by cortical atrophy, widening of the cerebral sulcus, large infarct lesion area and sparse cerebral white matter. Cranial MRI can effectively identify these features. The application of cranial MRI has some clinical values for early treatment and prognostic assessment.

Authors: Suleman Marriam , Ume Sughra  , Riaz Asmaa , Akbar Maheen
Published: January 2023

Objective: Early years of childhood form the basis of intelligence, personality, social behaviour, and capacity to learn and nurture oneself as an adult. Our objective was to find out the effects of screen time on behavior of pre-schoolers, which could provide scientific grounds to the control of digital screen time.

Method: A cross sectional survey was conducted in four private preschools of Islamabad from June -November 2021. A sample size of 200 children ages three-five years were selected through multistage random sampling using a parental questionnaire. Children were grouped based on daily screen time of ≤60 minutes or >60 minutes. Analysis was made based on the Child behavior checklist for ages eighteen months-five years results. Cronbach’s alpha coefficient was found to be 0.925. It was analyzed using SPSS version 22. Chi-square test, independent sample t-test and multi linear regression were applied to determine the association and significance levels between the variables.

Results: Study results indicate increased screen time was statistically significant with child’s age, education level and employment status of mothers. It was observed that pre-schoolers with screen time of > 60 minutes tend to suffer more from withdrawal syndrome (11.94±3.91, p = 0.014) sleep problems (10.97±3.20, p = 0.010) and Autism spectrum problems (17.66±5.89, p = 0.047) as compared to pre-schoolers with screen time ≤60 minutes. Strongest predictor of outcome variable was found to be mothers education level (ß = 21.53).

Conclusion: Study findings revealed that excessive screen time has deleterious effect and is associated with behavioural problems of pre-schoolers.

A rare case of Rhodococcus osteomyelitis
Authors: Tasnim Saria , Dave Dhara , Dweik Noor , Yaqoob Sinan , Tarek Naguib
Published: January 2023

Rhodococcus is a rare zoonotic infection causing cavitary pneumonia in immunocompromised humans. There had been very few reported incidences of Rhodococcus osteomyelitis. Our patient is a 27 years old male with human immunodeficiency virus (HIV) infection who was diagnosed with Rhodococcus osteomyelitis and bacteremia. He initially presented with right hip pain and was diagnosed with osteomyelitis and abscess based on a CT scan. IR guided drainage of the abscess was done and culture yielded R. equi. He failed antibiotic treatment multiple times and later was managed with surgical intervention. Although it is a rare case, physicians should keep it in mind especially in immunocompromised patients while deciding on diagnosis and treatment plans.
Cases with uncharacteristic bacteria in canaliculitis
Authors: Marsh Harrison , Pederson Addie , Ray Coby , Freedman Kenn
Published: January 2023

Canaliculitis is not considered to be a common condition and can be frequently misdiagnosed. The condition can also be challenging to eradicate. Canaliculitis accounts for 2-4% of lacrimal disease and is most often associated with Actinomyces israelii, Staphylococcus, and Strepococcus. However, these cases represent occasions of canaliculitis caused by uncharacteristic bacteria. We herein report three unique cases of canaliculitis that each required probing and irrigation of the infected lacrimal duct to culture bacteria following resistance to initial antibacterial treatment. Each case resulted in a different microbe, the cultures of the expelled purulent material grew Eikenella corrodens, Parvimonas micra, andCorynebacterium jeikeium respectively. All three cases occurred in rural west Texas woman with ages of 68, 70, and 40 years-old respectively. These cases highlight the importance of recognizing the possible involvement of uncharacteristic bacteria for the proper management of canaliculitis and proceeding to appropriate lacrimal procedures when empiric therapy is ineffective.
Pain management in the intensive care unit
Authors: Motes Arunee
Published: January 2023

Critically ill patients often experience pain from an underlying illness or injury, a recent surgical or other invasive procedure, or various interventions in the intensive care unit (ICU), e.g., endotracheal intubation, vascular access devices, nasogastric tubes, urinary catheters, mechanical ventilation, and routine nursing care, such as repositioning. Opioids remain the mainstay medication for pain control in the ICU; however, they can have adverse effects, including over-sedation, respiratory depression, opioid-induced constipation, opioid dependence and withdrawal, which result in increased length of ICU/hospital stay, health care costs, morbidity, and mortality. In this review, we summarize the mechanism of action, usual doses, side effects, recent studies of opioids that are frequently used in adult ICUs, and pain assessment tools for monitoring pain in adult ICU patients.

Ivermectin - an antiviral drug for the COVID-19 pandemic?
Authors: Peterson Christopher , Ammu Anusha , Mangwiro Audrey , Crist Christopher
Published: January 2023

Abstract
The use of ivermectin for the treatment of COVID-19 infections has been a subject of significant interest and controversy. The drug has a history of off-label use for a variety of clinical disorders and has shown some potential as an antiviral drug in in vitro studies and animal studies, and it has a relatively favorable safety profile. Multiple studies have been published examining the use of ivermectin against COVID-19. While several studies suggested it could be an effective therapeutic, most of these studies were insufficiently robust, had design flaws, or did not report any changes in important clinical outcomes, such as mortality. A smaller number of more robust studies did not support ivermectin use for COVID-19 treatment. Therefore, at present, ivermectin cannot be recommended for the treatment of COVID-19. While further studies may be warranted, this decision must be weighed against the possibility that this research may not alter current recommendations on the use of ivermectin in COVID-19 infections.

„Pismo uskrzydlonej ręki”, czyli Witkacy Heleny Blum Przyczynek do dyskusji o recepcji twórczości plastycznej Witkacego w kontekście surrealizmu
Authors: Graś-Godzwon Małgorzata
Published: January 2023

Helena Blum była krytyczką sztuki, muzealniczką i historyczką sztuki – jedną z pierwszych badaczek awangardy światowej oraz polskiej sztuki nowoczesnej. W 1932 roku obroniła pierwszy w Polsce dotyczący tej ostatniej dziedziny doktorat pt. Kierunki o typie konstrukcyjnym w nowoczesnej sztuce polskiej. Od 1944 roku mieszkała w Krakowie, wiążąc się na długo z tamtejszym Muzeum Narodowym. W latach 1944–1965 była kustoszką Galerii Polskiej Malarstwa i Rzeźby XX wieku, a w latach 1965–1973 pełniła funkcję jej kuratorki. W muzeum tym stworzyła podstawowy zbiór polskiej sztuki nowoczesnej, gromadząc dzieła przede wszystkim powojennych artystów krakowskich, jak również Witkacego. W 1957 roku zorganizowała wystawę grupy formistów, na której zaprezentowano m.in. dzieła Stanisława Ignacego Witkiewicza. Co istotne, Blum była związana ze środowiskiem przedwojennych i powojennych krakowskich awangardzistów, które uważało Witkacego za swego ojca duchowego. Wszystko wskazuje przy tym na to, że Helena Blum była współtwórczynią promowanego przez to środowisko wizerunku Witkacego jako artysty awangardowego, a jej rola okazała się istotna m.in. z uwagi na pozycję, jaką zajmowała w krakowskim Muzeum Narodowym i możliwość wykorzystania tej instytucji do promowania swej wizji. To właśnie Helena Blum była komisarzem wystawy monograficznej Witkacego zorganizowanej w 1966 roku, która przyczyniła się do ugruntowania jego wizerunku jako surrealisty.
Opłata za korzystanie z zezwoleń na sprzedaż napojów alkoholowych w czasie pandemii Covid-19
Authors: Szalewska Małgorzata
Published: January 2023

Opłata za korzystanie z zezwolenia na sprzedaż napojów alkoholowych jest instrumentem finansowym stosowanym wobec przedsiębiorcy, któremu udzielono zezwolenia na sprzedaż napojów alkoholowych. Przedmiotem obowiązku opłatowego jest stworzenie po stronie przedsiębiorcy sytuacji prawnej uprawniającej go do legalnego dystrybuowania napojów alkoholowych, co jest równoznaczne z korzystaniem z zezwolenia. Istoty przedmiotowej opłaty należy szukać w partycypacyjnym modelu udziału podmiotu, któremu przyznano prawo do sprzedaży napojów alkoholowych w kosztach likwidacji negatywnych skutków społecznych spożywania alkoholu. Wprowadzone w związku z epidemią SARS-Cov-2 ograniczenia działalności gospodarczej, stanowiące w istocie czasowe odebranie prawa do sprzedaży napojów alkoholowych przeznaczonych do spożycia w miejscu sprzedaży, stawiają pod znakiem zapytania materialną podstawę obowiązku uiszczania przedmiotowej opłaty. Przyjęte przez ustawodawcę rozwiązania, polegające na fakultatywnym upoważnieniu organów gminy do zwolnienia z obowiązku uiszczenia opłaty, należy uznać za nieadekwatne do zaistniałej sytuacji.

(Adult) education in the perspective of emotional geography. Towards a transdisciplinary approach in andragogy research
Authors: Góralska Renata
Published: January 2023

The aim of the article is to describe emotional geography, i.e. a research trend located on the borderline between human geography and contemporary affect studies, which focuses on the relationship between emotions and the broadly understood environmental, socio-cultural, spatial, economic, and political context. For this purpose, the author refers to theoretical analyses and research in the area of the so-called affective turn, and to the critical and political theories of emotions. She presents the relationship between education and emotional geography as well as examples of educational research projects on the socio-culturalspatial analyses of emotions and education. She also indicates the methodological implications for educational and andragogy research projects concerning the study of emotions in education, i.e. their transdisciplinary dimension. The presented way of conceptualizing the emotional geography of (in) education is a new look at the functioning of educational institutions and at the practice of lifelong learning. It can be a source of empirical research projects for theorists of education and andragogues.
The Ethics and Social Mission of Workers and their Relationship to Social Intrapreneurship.

Published: January 2023

El intraemprendimiento (es decir, el espíritu empresarial que surge dentro de organizaciones establecidas) es clave para el desarrollo de las entidades que lo generan. De ahí que se le atribuyan resultados altamente positivos. Este constructo ha sido analizado durante más de tres décadas; sin embargo, el intraemprendimiento social, que surge de la necesidad de las empresas de ser reconocidas como entidades que generan valor social a partir de su misión, carece aún de suficiente bagaje científico. Por ello, por primera vez, este estudio evalúa empíricamente la misión social y la ética empresarial como determinantes del intraemprendimiento social. Se utilizó un cuestionario para recopilar datos de 603 profesionales de diferentes empresas de Baja California y México. Entre las técnicas de análisis de datos, se utilizó estadística descriptiva para verificar la composición univariada de los datos, y estadística inferencial para determinar la confiabilidad y validez de las escalas de medición. Los datos indican una relación altamente significativa entre la misión social corporativa y el intraemprendimiento social; sin embargo, los datos indican que la ética empresarial no está relacionada con los actos de intraemprendimiento social.
Pensamiento de diseño y marcos éticos para la Inteligencia Artificial: una mirada a la participación de las múltiples partes interesadas
Authors: Florez Rojas Maria Lorena
Published: January 2023

Los marcos regulatorios, que determinan la participación de las partes interesadas, deben respetar los principios para una participación eficaz y que sea oportuna, inclusiva, transparente e iterativa. Sin embargo, la creación e implementación de marcos regulatorios sobre temas innovadores, en ocasiones, suele estar sesgada por una parte dominante en la discusión. Este artículo demuestra cómo el enfoque del pensamiento de diseño, principalmente en su fase de co-creación, es potencialmente propicio para la creación e implementación de las denominadas estrategias de Inteligencia Artificial (ia), debido a su énfasis en el respeto por la dignidad humana y otros atributos fundamentales, como la empatía, aunque plantea diversos retos para su aplicación. Este enfoque se basa en una metodología deductiva, a través del proceso de creación y socialización de las estrategias para la ia, que fueron desarrollados en Canadá y Colombia.

Background/Aims

Whole body vibration could benefit functional mobility in people with Parkinson's disease. A preliminary study was undertaken to analyse the acute effect of whole body vibration on unobstructed walking and obstacle circumvention in people with Parkinson's disease.

Methods

People with Parkinson's disease and typically healthy individuals as matched controls were divided into four groups with nine individuals in each: experimental or placebo for people with Parkinson's disease and experimental or placebo for the control group. The participants were evaluated in two different gait conditions: unobstructed walking and obstacle circumvention. Then the participants undertook a session of whole body vibration on a KIKOS P201 lateral vibratory platform in two positions: feet shoulder-width apart, and feet shoulder-width apart with slightly flexed knees. The participants were re-evaluated after this session.

Results

After whole body vibration, those in the experimental Parkinson's disease group had a reduced co-contraction of the tibialis anterior and the gastrocnemius lateralis muscles during unobstructed walking, whereas the co-contraction of the tibialis anterior and the gastrocnemius lateralis muscles increased in the experimental control group. In addition, those in the experimental control group had reduced stride duration in unobstructed walking and in obstacle circumvention. After the placebo intervention, the co-contraction of the tibialis anterior and the gastrocnemius lateralis muscles increased in all conditions and stride duration was reduced in unobstructed walking.

Conclusions

Although whole body vibration had no acute efficiency on gait (unobstructed walking and obstacle circumvention), it can improve other components, such as strength, which could be important for people with Parkinson's disease.

Authors: VR Vijay , Kang Harmeet Kaur
Published: January 2023

This study aimed to examine the effect of nurse-led interventions on non-adherence to dietary and fluid restrictions among adults receiving haemodialysis. A randomised, controlled trial design was used for this study. While the interventional group received nurse-led interventions in addition to routine care, the control group received only standard care. The current study found that, in the intervention group, the number of non-adherence days to diet (p=0.001) and fluid (p=0.001) restrictions have significantly decreased after the interventions. Furthermore, the between-group analysis depicted a statistically significant reduction of non-adherence days in the intervention group compared to the control group at week 10 for both diet (p=0.018) and fluid (p=0.003). However, the objective adherence to diet and fluid restrictions, based on the composite scale, showed no statistically significant improvement in the proportion of adherence in the intervention group after the interventions.
Neospora in UK cattle
Authors: Jerram Lucy
Published: January 2023

Neosporosis was first identified in the 1980s and has since become well established as an endemic disease of cattle and a significant cause of abortion. Neospora caninum is an obligate, intracellular, protozoal parasite that relies on intermediate and definitive hosts to complete its lifecycle. Neospora infection leaves cattle three to thirteen times more likely to abort than a healthy animal. Calves may be born alive but be latently infected owith Neospora or have obvious defects. Disease transmission can be horizontal, when cattle ingest feed contaminated with infected dog faeces that results in latency or exogenous transplacental infection, or vertical when latent infection recrudesces, producing a congenitally infected calf. Testing involves serology or direct testing if abortion material is available. Serology can provide a presumptive diagnosis when carried out near in time to an abortion event. Eradicating the disease involves identifying infected cows and infected family lines through serology and removing these individuals from the herd. This approach takes time because seropositive cows do not always return positive tests, and in a herd with a high seroprevalence it is not economically viable to remove large numbers of animals.

Various investigations have applied meditation protocols in the school context, with beneficial effects. Transcendental meditation, however, received little attention in primary school settings and few controlled studies are available. The present study is aimed: 1) to investigate the implementation of a school protocol (Quiet Time-QT) based on Transcendental Meditation ™ in a primary school setting 2) to test its efficacy in promoting strengths and resilience in children, using a controlled research, with a cross over design. 92 students attending fourth and fifth class of a primary school were assigned to either the QT intervention, or to a waiting list condition. Children assigned to the waiting list received the QT protocol after few months. Before and after the intervention children were evaluated by their teachers using the Strengths and Difficulties Questionnaire (SDQ) and the Devereux Student Strengths Assessment (DESSA). A Repeated Measures MANOVA was applied to compare the two groups. After the QT intervention children in the experimental condition showed fewer emotional and behavioral difficulties (SDQ) compared to children in the waiting list. An overall positive effect of QT was observed in the total sample in improving children’s strengths and emotional well-being. Participants enjoyed the practice of meditation in the school setting. Conclusions: the results of this controlled investigation showed that the QT school protocol is feasible in the school setting, and it yielded improvements in children’s strengths and well-being. Meditation programs could be easily included in the educational system to sustain children positive development.

The photocatalytic efficiency is often limited by the low utilization of visible light and the rapid recombination of photogenerated carriers. In this work, we successfully synthesized BiOCOOH micro-flowers self-assembled from two-dimensional nanosheets using N,N-dimethylformamide and Bi(NO3)3·5H2O as raw materials. The characterizations such as XRD, SEM, TEM, and EDS proved the success of Fe3+ doping into the lattice of BiOCOOH. By degrading the colored dye RhB, it was found that 0.8FBOC has the best photocatalytic performance, and its degradation rate constant is 0.013 min-1, which is 6 times than pure BiOCOOH. According to previous works, the intermediates generated during the photodegradation of RhB in this work were investigated and we speculate the possible photocatalytic mechanism at the end. Up to now, we have hardly discovered about the doping modification of BiOCOOH, so this study offers a new idea for the modification of BiOCOOH.

Nuevas tendencias en metodologías docentes: la gamificación en el Grado de Trabajo Social.
Authors: Polanco Grullón Fidely
Published: January 2023

Una de las consecuencias de la COVID-19 ha sido provocar que los/las docentes de la Educación Superior hayan tenido que mejorar e incluso adaptar las metodologías utilizadas desde siempre, es decir, la docencia considerada como magistral. Todo esto con el fin de renovarse y adaptarse al nuevo panorama y a lo que todo ello conlleva. La nueva incorporación de estos procesos y herramientas relacionadas con el uso de la tecnología, buscan que, a través de la innovación docente, el alumnado se sienta más motivado y pueda adquirir un mayor aprendizaje. Por ello, con este artículo se pretende reflexionar sobre los beneficios del uso de la gamificación como técnica de enseñanza-aprendizaje en el contexto universitario. Así como también su uso como complemento a los recursos a disposición del/la docente universitario/a, en el que se busque favorecer desarrollar y adquirir de forma óptima las competencias del alumnado del Grado en Trabajo Social. Para ello, se ha realizado una revisión de la literatura científica de fuentes primarias y secundarias desde una metodología cualitativa, en concreto desde la hermenéutica crítica, sobre la técnica de la gamificación en el área de Trabajo Social. Los resultados iniciales señalan que la impartición de la docencia en la Educación Superior se ha visto transformada debido a la COVID-19. Los/las docentes han tenido que ver la necesidad y la importancia del uso de las Tecnologías de la información y la Comunicación (TIC) en su día a día en el aula.
Amplified radio-over-fiber system linearization using recurrent neural networks

Published: January 2023

Ubiquitous communication is an emergent feature of the future sixth generation of mobile communication (6G) networks. One of the main challenges of this upcoming mobile network is providing broadband communication wherever connectivity is necessary, including rural areas. Up to now, all previous generations of mobile networks have not satisfactorily accomplished this task, and the high cost of deploying and maintaining complex communication infrastructure in remote areas is one of the main reasons. The centralized radio access network might play an important role in overcoming it, since it enables all baseband centralization in a central office (CO), simplifying network deployment and reducing operating/maintenance costs. Additionally, in this scenario, the radio over fiber (RoF) system might be used for transporting analog signals from the CO to a simplified remote base station, composed only of an optical detector and radio-frequency front-end. However, the Mach–Zehnder modulator and power amplifier, commonly employed in RoF systems, introduce undesired nonlinear effects that can severely degrade overall system performance and prohibitively increase the out-of-band emission. We investigate the use of machine learning (ML) algorithms applied to the linearization of an electrical-amplified RoF system. Particularly, a memory recurrent neural network (RNN) linearization is proposed and compared with a memoryless multilayer perceptron linearization. The root mean square error vector magnitude, normalized mean square error, and adjacent channel leakage ratio metrics have been calculated to evaluate the performance of our ML-based approach. Numerical results demonstrate promising linearization performance when the RNN memory depth is equal to or higher than the amplified-RoF system memory depth.
