Authors: Leduc Cedric , Weaving Dan , Owen Cameron , Ramirez-Lopez Carlos , Chantler Sarah , Aloulou Anis , Tee Jason , Jones Ben
Published: August 2022

Background

Elite rugby players experience poor sleep quality and quantity. This lack of sleep could compromise post-exercise recovery. Therefore, it appears central to encourage sleep in order to improve recovery kinetics. However, the effectiveness of an acute ergogenic strategy such as sleep extension on recovery has yet to be investigated among athletes.

Aim

To compare the effects of a single night of sleep extension to an active recovery session (CON) on post-exercise recovery kinetics.

Methods

In a randomised cross-over design, 10 male rugby union players participated in two evening training sessions (19:30) involving collision activity, 7-days apart. After each session, participants either extended their sleep to 10 hours or attended an early morning recovery session (07:30). Prior to (PRE), immediately after (POST 0 hour [h]), 14h (POST 14) and 36h (POST 36) post training, neuromuscular, perceptual and cognitive measures of fatigue were assessed. Objective sleep parameters were monitored two days before the training session and over the two-day recovery period.

Results

The training session induced substantial decreases in countermovement jump mean power and wellness across all time points, while heart rate recovery decreased at POST 0 in both conditions. Sleep extension resulted in greater total sleep time (effect size [90% confidence interval]: 5.35 [4.56 to 6.14]) but greater sleep fragmentation than CON (2.85 [2.00 to 3.70]). Between group differences highlight a faster recovery of cognitive performance following sleep extension (-1.53 [-2.33 to -0.74]) at POST 14, while autonomic function (-1.00 [-1.85 to -0.16]) and upper-body neuromuscular function (-0.78 [-1.65 to 0.08]) were better in CON. However, no difference in recovery status between groups was observed at POST 36.

Conclusion

The main finding of this study suggests that sleep extension could affect cognitive function positively but did not improve neuromuscular function the day after a late exercise bout.
Maternal exposure to intimate partner violence and uptake of maternal healthcare services in Ethiopia: Evidence from a national survey
Authors: Ousman Seman K. , Gebremariam Mekdes K. , Sundby Johanne , Magnus Jeanette H.
Published: August 2022

Background

Women exposed to Intimate Partner Violence (IPV) often do not utilize maternal health care optimally both because of stigma and other social problems. The current study aims to explore an association between maternal healthcare seeking and violence exposure among Ethiopian women and to assess if educational attainment and wealth status moderate this association.

Methods

The analyses included 2836 (weighted) currently married women with one live birth. We focus on the five years preceding the 2016 Ethiopian Demographic and Health Survey (EDHS) who participate, in the domestic violence sub-study. Exposure was determined by maternal reports of physical, emotional, sexual IPV or any form of IPV. The utilization of antenatal care (ANC) and place of delivery were used as proxy outcome variables for uptake of skilled maternal healthcare utilization. Women’s education attainment and wealth status were selected as potential moderators, as they can enable women with psychological and financial resources to counteract impact of IPV. Multilevel logistic regression analyses were used to explore the association between spousal IPV and maternal health outcomes. Moderation effects by education and wealth status were tested, and the data stratified. Using statistical software Stata MP 16.1, the restricted maximum likelihood method, we obtained the model estimates.

Results

About 27.5% of the women who reported exposure to any form of IPV had a health facility delivery. While 23.4% and 22.4% visited four or more antenatal care services among mothers exposed to emotional IPV and sexual IPV, respectively. After adjusting for potential confounding factors, only the association between maternal exposure to emotional IPV and adequate use of ANC was statistically significant (OR = 0.73, (95% CI:0.56–0.95)). But we found no significant association between IPV and utilization of health facility delivery. Some moderation effects of education and wealth in the association between IPV and maternal healthcare service utilization outcome were found.

Conclusion

Exposure to emotional IPV was associated with poor uptake of maternal health care service utilization for married Ethiopian women. While developing interventions to improve women’s maternal healthcare service use, it is crucial to consider the effects of socio-economic variables that moderate the association especially with the intersection of IPV.
Primary headaches increase the risk of dementias: An 8-year nationwide cohort study
Authors: Kim Seon-Jip , Park Sang Min , Cho Hyun-Jae , Park Ji Woon
Published: August 2022

Background

Headache, a highly prevalent neurological disorder, has consistently been linked with an elevated risk of dementia. However, most studies are focused on the relationship with migraine in limited age groups. Therefore, the objective of this research was to look at the link between various type of headaches and dementias based on longitudinal population-based data.

Methods and results

Participants diagnosed with headache from 2002 to 2005 were selected and major covariates were collected. The diagnoses of Alzheimer’s disease, vascular dementia, and other dementias were observed from 2006 until 2013. The adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) of dementias according to headache type were calculated by Cox proportional hazards regression. A number of 470,652 participants were observed for a mean of 7.6 years (standard deviation: 1.2), for approximately 3.6 million person-years. Both tension type headache (TTH) and migraine elevated the risk of all-cause dementias (TTH, aHR 1.18, 95% CI 1.13–2.24; migraine, aHR 1.18, 95% CI 1.13–2.24). Headaches had a greater influence in females and non-smokers as a risk factor of dementias. Patients with migraine who consumed alcohol had a higher risk of dementia, however this was not true with TTH patients. Among participants without comorbidities, TTH patients were more susceptible to dementia than migraine patients. Headache patients had a higher proportion of females regardless of headache type and approximately 1.5 times more individuals had three or more comorbidities compared to those without headache.

Conclusions

Headache could be an independent predictor for subsequent dementia risk. Future studies should focus on clarifying pathogenic pathways and possible dementia-related preventive measures in headache populations.
FGFRL1 and FGF genes are associated with height, hypertension, and osteoporosis
Authors: Cho Hye-Won , Jin Hyun-Seok , Eom Yong-Bin
Published: August 2022

Hypertension and osteoporosis are two major disorders, which interact with each other. Specific genetic signals involving the fibroblast growth factor receptor-like 1 (FGFRL1) gene are related to high blood pressure and bone growth in giraffes. FGFRL1 is associated with cardiovascular system and bone formation. We performed an association study to investigate the role of FGFRL1 in hypertension, osteoporosis, and height determination in humans. In addition, we identified three kinds of phenotypes in fibroblast growth factor (FGF) genes and examined their association with the FGFRL1 gene. We identified 42 SNPs in the FGFRL1 gene associated with each trait. We then analyzed the potential functional annotation of each SNP. The FGFRL1 gene was found to be associated with height, hypertension, and osteoporosis, consistent with the results of a previous study. In addition, the FGF2, FGF4, FGF10, FGF18, and FGF22 genes were found to interact with the FGFRL1 gene. Our study suggests that both FGFRL1 and FGFRL1-related genes may determine the height and the prevalence of osteoporosis and hypertension in the Korean population.

Published: August 2022

In 2018, the World Health Organization recommended a 6-month four-drug regimen (rifampicin, ethambutol, pyrazinamide, and levofloxacin) for the treatment of isoniazid-monoresistant tuberculosis. However, the regimen had very low certainty. This cohort study assessed the impact of fluoroquinolone use and initial baseline regimen on treatment effectiveness in isoniazid-monoresistant tuberculosis. This multicenter retrospective cohort study included 318 patients with isoniazid-monoresistant tuberculosis notified between 2011 and 2018 in Korea. Baseline regimens were classified into two groups, namely 6–9-month rifampicin, ethambutol, and pyrazinamide (6-9REZ) and a combination regimen of 2-month rifampicin, ethambutol, pyrazinamide and 7–10-month rifampicin and ethambutol (2REZ/7-10RE). Multivariable logistic regression was performed to assess factors associated with positive treatment outcomes. Of 318 enrolled patients, 234 (73.6%) were treated with the 6-9REZ and 103 (32.4%) with additional fluoroquinolone. In a multivariable logistic regression model comparing the 6-9REZ and 2REZ/7-10RE groups, there was no difference in the odds of positive outcomes (adjusted odds ratio = 1.08, 95% confidence interval = 0.65–1.82). Addition use of fluoroquinolone was not associated with positive treatment outcomes in the whole cohort (adjusted odds ratio = 1.41, 95% confidence interval = 0.87–2.27); however, its additional use was beneficial in the 2REZ/7-10RE subgroup (adjusted odds ratio = 3.58, 95% confidence interval = 1.32–9.75). Both initial baseline regimens, 6-9REZ and 2REZ/7-10RE, were similarly effective. Shortening of the pyrazinamide administration duration with additional fluoroquinolone use could be a safe alternative for patients with potential hepatotoxicity related to pyrazinamide.

Published: August 2022

Objective

The primary aim of the study was to determine levels of literacy in both oral health and orthodontics in an adult population. The secondary study aim was to investigate differences in literacy between males and females.

Methods

Participants included individuals 18 years or older seeking dental treatment at the East Carolina University (ECU) School of Dental Medicine. To determine levels of oral health literacy (OHL) and orthodontic literacy (OrthoL), validated instruments were administered, including the Rapid Estimate of Adult Literacy in Medicine and Dentistry, the Oral Health Literacy Instrument and its separate scales, and a questionnaire on orthodontic literacy. Summary statistics were computed, and statistical significance was set at 0.05.

Results

One hundred seventy-two individuals participated in the study and had a mean age of 55.03 (range:18–88). Greater than 70% of the sampled population exhibited inadequate or marginal oral health knowledge. Additionally, greater than 70% of the sample possessed no more than an 8th grade reading level, with regard to basic medical and dental terms. Higher education was weakly associated with higher OrthoL and OHL. Higher age was also weakly associated with lower OrthoL and OHL. Males on average exhibited significantly higher OHL (p < .05) but there were no OrthoL differences between males and females. Dental visit frequency was not associated with OrthoL or OHL.

Conclusion

Low levels of OrthoL and OHL were observed in the study. While males demonstrated a higher level of OHL than females, neither age nor the occurrence of dental appointments significantly influenced levels of literacy.
Ad-hoc preoperative management and respiratory events in pediatric anesthesia during the first COVID-19 lockdown–an observational cohort study
Authors: Zadrazil Markus , Marhofer Peter , Schmid Werner , Marhofer Melanie , Opfermann Philipp
Published: August 2022

Background

Early pre-anesthetic management for surgery is aimed at identifying risk factors, which notably in children are mostly airway related. The first COVID-19 lockdown opened a unique ‘window of opportunity’ to study what impact an ad-hoc management strategy would bring to bear on intraoperative respiratory events.

Methods

In this observational cohort study we included all patients with an American Society of Anesthesiology (ASA) Physical Status of I or II, aged 0 to ≤18 years, who underwent elective surgery at our center during the first national COVID-19 lockdown (March 15thto May 31st, 2020) and all analogue cases during the same calendar period of 2017−2019. The primary outcome parameter was a drop in peripheral oxygen saturation (SpO2) below 90% during anesthesia management. The study is completed and registered with the German Clinical Trials Register, DRKS00024128.

Results

Given 125 of 796 evaluable cases during the early 2020 lockdown, significant differences over the years did not emerge for the primary outcome or event counts (p>0.05). Events were exceedingly rare even under general anesthesia (n = 3) and non-existent under regional anesthesia (apart from block failures: n = 4). Regression analysis for SpO2events <90% yielded no significant difference for ad-hocvsstandard preoperative management (p = 0.367) but more events based on younger patients (p = 0.007), endotracheal intubation (p = 0.007), and bronchopulmonary procedures (p = 0.001).

Conclusions

Early assessment may not add to the safety of pediatric anesthesia. As a potential caveat for other centers, the high rate of anesthesia without airway manipulation at our center may contribute to our low rate of respiratory events.
Using systems-mapping to address Adverse Childhood Experiences (ACEs) and trauma: A qualitative study of stakeholder experiences
Authors: Vu Thi Hoang , Bishop Jared , McGill Leigh , Valmadrid Luke , Golden Shelley , Emmerling Dane , Saeugling Seth
Published: August 2022

Adverse childhood experiences (ACEs) and trauma have been linked to decreased psychosocial and physiological health functioning. While various individual and community-level interventions to address ACEs have been reported, one novel approach that has not been explored in detail is a community-engaged causal loop diagramming project, or systems mapping project (SMP), in which diverse stakeholders work together to document the forces that are creating the outcomes and patterns within the community. To better document and understand the impact of participation in an SMP, we conducted in-depth, qualitative interviews with 16 stakeholders who were involved in a systems-mapping process facilitated by a local nonprofit in Eastern North Carolina. We used an iterative, content analysis coding process to generate and analyze themes from these interviews. Three major themes emerged: 1) Recognition and understanding of own trauma, 2) Trauma as both a community issue and an individual issue, and 3) Systems-mapping as a conceptual tool with practical benefits. All participants strongly recommended the systems-mapping approach to other communities and believed that it is a valuable tool for empowerment and provided several considerations for future organizers of similar systems-mapping projects. Our findings suggest that systems mapping is a feasible, transferable, and promising modality for understanding and addressing ACEs at the individual, interpersonal, and community-levels, as well as for putting community voices at the forefront of efforts to address ACEs.

Exploring online art education: Multi-institutional perspectives and practices
Authors: Song Borim , Lim Kyungeun
Published: August 2022

How can art educators transmit their passion and enthusiasm for art teaching and learning to cultivate human potential in the virtual classroom? As a collective case study focusing on our online undergraduate courses, this research examines how two instructors used instructional methods and technologies, and how their students responded to their pedagogical endeavours. Qualitative content analysis was utilized. Virtual art classes can encourage students to look into themselves and become more aware of themselves. Communicating and feeling connected to others are critical for students in online settings. As demonstrated in our course design, connectivity between students and instructors can be facilitated through a multilayered structure, providing for more efficient communication. This study also found blurred boundaries between real and virtual learning environments. When we facilitate fluidity and conceptual flexibility as online art educators, digital technologies may expand our thinking and expression frameworks.
Reconciliation with the pain through embracing the past: Message of hope and resilience via the Ugaritic alphabet

Published: August 2022

After witnessing my home country suffering through a vicious civil war, this inquiry initially intended to represent Syria in a positive light, as a place of civilization, differently to what we have been constantly seeing in the news in recent years. However, the research led me to more meaningful discoveries. With the help of Syrian participants, I discovered not only a way to promote the country as a place of peace and prosperity, but also a way to invite the viewer to reconcile with grief and adversity they have experienced by embracing the word ‘hope’. In this visual essay, I share an invitation to reconcile with one’s self, past and hardship through the Ugaritic alphabet.
An alternate tracing as arts-based inquiry: Recognizing past-present trajectories of schooling and Whiteness in an art student-teacher observation
Authors: Hanawalt Christina
Published: August 2022

In this article, I revisit an art student-teacher observation in an elementary school in which I encountered unsettling approaches to discipline practices. Using process philosophy as a theoretical guide, I describe my arts-based inquiry into what transpired in the school that day as events that were produced in a field of relations. Sensing that there was something I was not initially able to recognize about the field of relations from which the events were catalysed, I pursued an alternate tracing of the events as juxtaposed with texts relevant to the history of schooling in the United States. This process brought to the fore the role of Whiteness – past and present – in the disciplinary norms around which schooling in the United States is centred. I further explore the role of Whiteness in the disciplining of bodies, sounds, affects and emotions in schools – all of which affect students’ and teachers’ ways of being in art classrooms.

Authors: Gitau George Karuoya , Kimeli Peter , Ikiror Davis , Mwangi Willy , Machuchu Douglas , Gakuru Moses Irungu , Owuor Genevieve
Published: August 2022

Background and Aim: Camels have adaptive features to harsh climatic conditions, which make them a valued stable source of livelihood in arid lands. This study estimated the total bacterial and coliform counts (CCs), their associated factors in raw camel milk from the pastoral camel keepers, and the entire milk value chain in Isiolo County and Nairobi, Kenya. This study elucidates the bacterial load in camel milk and its potential risk. Moreover, this study provides recommendations on how to avert a human health hazard.

Materials and Methods: This cross-sectional study targeted the camel pastoralists in Isiolo County, in the northern central part of Kenya. The study was conducted in July and August 2021. In addition, camel milk samples were collected along the value chain key points, including the producers, transporters, one bulker, and small traders in Isiolo town, and other retailers in Nairobi City. Eight camel herds were purposively selected and visited for a sample collection from pooled milking containers (10 mL each). In addition, milk was collected from pooled milk through the transporters, two milk bulkers, and several milk retailers in Isiolo town. Milk was further collected from retailers in Eastleigh town, Nairobi City. At each sampling point, 20 mL of milk sample was collected aseptically. The milk samples were assessed for total viable bacterial counts (TVBC) and CCs using the plate count and digital colony count, respectively.

Results: A total of 76 respondents were selected and 213 milk samples were collected in this study. The respondents included the 1 (1.3%) bulker, 32 (42.1%) producers, 26 (34.2%) traders, and 17 (22.4%) transporters. Most respondents were male (62%), with most being over 40 years old. Overall, the TVBC had a mean of 2436835 ± 9276636 and a median of 3600. Furthermore, the multivariable multilevel mixed-effects linear regression model indicated that gender and practice of smoking milk-handling containers were positively and negatively associated with high counts of the natural logarithm of total viable bacteria, respectively. Of the milk samples evaluated for the CC, 10.3% (22/213) had counts greater than or equal to (≥) 100,000, where some also indicated extreme outliers of about 9.3 million.

Conclusion: This study reports a low proportion of camel milk samples with high total viable bacterial and CCs. The material of the milk container and level of education interactively affected the total viable bacteria.

Published: August 2022

Academic visitor programs aim to enhance university teachers’ teaching and research capacity and intercultural competence. Its impact, however, has remained under-researched. Using the data collected from two rounds of in-depth interviews with 13 Chinese university English teachers over a year and a half, this study explored their experiences as academic visitors in the UK through the lens of professional identity. Findings revealed that the participants came with various expectations and negotiated and constructed different identities during their academic visits. The participants’ developing identities in turn affected their investment in their professional development in their situated contexts. The study provides important implications for academic visit programs which need to be designed in line with the complex needs and identities of university teachers.

Published: August 2022

The prominent ear is the most common congenital ear disorder. Some of its discovered features include the overdeveloped concha and the underdeveloped antihelix. The present study focuses on the analysis of the conchal bowl, while assessing its depth before and after otoplasty. Despite its anatomical and surgical importance for the correction of protruding ears, that ear structure has been little discussed in the literature. With the aim of contributing, by providing fresh information, an attempt was made to recognize a surgical parameter of the concha, while assisting in the perception of the depth change after its partial resection, as well as to compare that change to the thickness of the studied cartilage, and to show the statistical data of that structure in the prominent ear. While reviewing the data from the study, it was noted that the mean conchal bowl depth of patients with prominent ears pre-otoplasty surgery was approximately 17 millimeters (mm). In the late postoperative period, a value of approximately 12 mm was reached. That means a mean depth difference of 5 mm in the surgical evolution, with no statistically significant difference between sexes, ear cartilage grading, and operated ear side. Most of the ears (96.9%) showed an increase in the conchal depth postoperatively, which is the main goal of every surgeon when performing conchal resection.

Linear regularized finite difference scheme for the quasilinear subdiffusion equation
Authors: Lapin Alexander , Laitinen Erkki
Published: August 2022

A homogeneous Dirichlet initial-boundary value problem for a quasilinear parabolic equation with a time-fractional derivative and coefficients at the elliptic part that depend on the gradient of the solution is considered. Conditions on the coefficients ensure the monotonicity and Lipschitz property of the elliptic operator on the set of functions whose gradients in space variables are uniformly bounded. For this problem, a linear regularized mesh scheme is constructed and investigated. A sufficient condition is derived for the regularization parameter that ensures the so-called local correctness of the mesh scheme. On the basis of correctness and approximation estimates for model problems with time-fractional Caputo or Caputo–Fabrizio derivatives, accuracy estimates are given in terms of mesh and regularization parameters under the assumption of the existence of a smooth solution to the differential problem. The presented results of the numerical experiments confirm the obtained asymptotic accuracy estimates.

El estudio determinó la presencia de material particulado (MP) emitido por el volcán Popocatépetl los días 29 y 31 de marzo de 2019 en el trayecto Atlixco-Puebla. El objetivo fue identificar tamaño y naturaleza química del MP en esta zona y reconocer el impacto en la salud (por inhalación) y el ambiente, así como comparar las cenizas de los años 1994, 2012 y 2019. El MP suspendido se cuantificó con un contador DT-9880, los metales totales y lixiviados se calcularon por espectrofotometría de absorción atómica (EAA) y la caracterización de cenizas se realizó por difracción de rayos X (DRX), espectroscopia de infrarrojo (FTIR-ATR) y espectroscopia de energía dispersiva (EDS)/microscopia electrónica de barrido (SEM). El 99.9% del MP presentó de 0.3 a 2.5 micrómetros (µm) de metales totales: cromo (8.5 ppm), cobre (0.61 ppm), magnesio (99.9 ppm) y zinc (39 ppm). La lixiviación fue desde 0.05% a 2.5% de metales totales. Se encontraron diferencias morfológicas significativas en la porosidad y tamaño de partícula de las cenizas. Monitorear el MP en esta área permite proponer medidas de atenuación por afectaciones a la salud y ambientales.

Background and Purpose:

Falling among older adults is common and can cause chronic health complications. Fear of falling, a lasting concern about falling that can lead an individual to avoid activities he or she can perform, is strongly associated with falling and fall risk. Although White older adults fall more often, Black older adults have more fall risk factors. The purpose of this study was to investigate factors that explain fear of falling and differences between White and Black community-dwelling older adults in fear of falling, balance confidence, and fall risk factors.

Methods:

Using a cross-sectional, retrospective design, 84 community-dwelling older adults (mean age [SD] = 69.0 [5.2], range: 55-80; White, n = 37, 44%; Black, n = 47, 56%, M/F = 20/64) were assessed. Assessments were conducted in a laboratory for human studies. Fall history and risk factors, and subjective fear of falling, were collected. The Montreal Cognitive Assessment (MoCA), Activities-Specific Balance Confidence (ABC) score, preferred, backward, and fast Gait Speed, Short Form-12 Physical and Mental Component Scores, fear of falling rating scale, and demographics questionnaires were administered. Analyses included a proportional odds logistic regression model to examine which factors predicted ABC score and which factors were associated with subjective fear of falling, 1-way analysis of variance for continuous variables, the Fisher exact test for categorical variables, and the Mann-Whitney-Wilcoxon test for ordinal variables.

Results:

Black participants had significantly fewer years of education (P = .007), lower MoCA scores (P = .002), and slower fast gait speed (P = .032) than White participants. Black participants reported less subjective fear of falling (P = .043). In the final ABC model (Akaike information criterion 208.26), lower ABC scores were predicted by White race, slower preferred and fast gait speeds, and worse Short Form-12 Mental Composite Scores.

Discussion:

Despite Black participants demonstrating typical characteristics of higher fall risk including lower cognitive scores, slower gait speed, and lower ABC scores, Black participants reported fewer falls. Understanding racial differences is an important factor in fear of falling and balance confidence.

Conclusion:

Reasons for racial differences should be examined further in fear of falling and balance confidence to facilitate the development of patient-centered falls prevention physical therapy programs.

Objective: This study was aimed at investigating the effects of preoperative treatment with a loading dose of statins combined with a PCSK9 inhibitor on coronary blood perfusion and short-term cardiovascular adverse events in patients with ST-segment elevation myocardial infarction (STEMI).

Method: Sixty-five patients with STEMI who had visited the Shanxi Cardiovascular Disease Hospital between May 2018 and May 2021 were enrolled in the study. The enrolled patients had no history of oral statins or antiplatelet therapy. The patients were divided into a combined treatment group (loading dose of statins combined with PCSK9 inhibitors, 35 patients) and a routine treatment group (loading dose of statins only, 30 patients). The primary endpoints were thrombolysis in myocardial infarction (TIMI) blood flow grading, corrected TIMI frame count (CTFC), and TIMI myocardial perfusion grading (TMPG), immediately after and 30 days after the operation. The secondary endpoint was a composite endpoint of cardiovascular death, nonfatal myocardial infarction, and target vessel revascularization 30 days after the operation.

Results: The combined treatment group had significantly lower CTFC (14.09±8.42 vs 26±12.42, P=0.04) and better TMPG (2.74±0.61 vs 2.5±0.73, P=0.04) than the routine treatment group immediately after the operation. Similarly, the combined treatment group had a significantly lower CTFC (16.29±7.39 vs 26.23±11.53, P=0.04) and significantly better TMPG (2.94±0.24 vs 2.76±0.43, P=0.01) than the routine treatment group 1 month after the operation.

Conclusion: Preoperative treatment with a loading dose of high-intensity statins combined with PCSK9 inhibitors increased coronary blood flow and myocardial perfusion after emergency thrombus aspiration in patients with STEMI. However, the treatment did not significantly decrease the incidence of cardiovascular death, nonfatal myocardial infarction, or target vessel revascularization.
Dscam1 Has Diverse Neuron Type-Specific Functions in the DevelopingDrosophilaCNS

Published: August 2022

Two key features endowDrosophilaDown syndrome cell adhesion molecule 1 (Dscam1) with the potential to provide a ubiquitous code for neuronal arbor self-avoidance. First, Dscam1 contains three large cassettes of alternative exons, so that stochastic alternative splicing yields 19,008 Dscam1 isoforms with different Ig ectodomains. Second, each neuron expresses a different subset of Dscam1 isoforms, and isoform-specific homophilic binding causes repulsion. This results in even spacing of self-arbors, while processes of other neurons can intermingle and share the same synaptic partners. In principle, this Dscam1 code could ensure arbor spacing of all neurons inDrosophila. This model is strongly supported by studies on dendrite spacing in the peripheral nervous system and studies on axonal branch segregation during brain development. However, the situation is less clear for central neuron dendrites, the major substrate for synaptic input in the CNS. We systematically tested the role of Dscam1 for dendrite growth and spacing in eight different types of identified central neurons. Knockdown of Dscam1 causes severe dendritic clumping and length reductions in efferent glutamatergic and aminergic neurons. The primary cause for these dendritic phenotypes could be impaired self-avoidance, a growth defect, or both. In peptidergic efferent neurons, many central arbors are not formed, arguing for a growth defect. By contrast, knockdown of Dscam1 does not affect dendrite growth or spacing in any of the five different types of interneurons tested. Axon arbor patterning is not affected in any neuron type tested. We conclude that Dscam1 mediates diverse, neuron type-specific functions during central neuron arbor differentiation.

Authors: AKTAŞ Nesimi
Published: August 2022

Dry ground meat is a cooked meat product. It is a popular meat product in Central Anatolian Region of Turkey. Calf plate or flank meats and intermuscular fats are used in the production of dry ground meat. In this study, sorption isotherms were determined using nine different salt solutions (0.1-0.9 aw) having different relative humidity values at 5, 15 and 25°C. From the experimental data obtained, it was found that the sorption isotherms had Type-II characteristics. The obtained experimental data were applied to Iglesias-Chirife, Oswin, BET, Harkins-Jura, Smith, Henderson, Halsey, GAB, Peleg. Iglesias-Chirife and Peleg equations were revealed the best fitting. Isosteric heats of adsorption were evaluated by applying the Clausius-Clapeyron equation to experimental isotherms and decreased with increasing moisture content.

Stretchability of knitwear is one of the most important factors of wearing comfort. Elasticity of knitted structures in course wise direction is usually higher than along wales and often characterized by crosswise shrinkage. Existing methods of knitting program development do not consider the real rate of wale wise shrinkage of rib knitted structure under the course wise extension. During the study experimental research has been carried out to fulfill empirical data on the relationship between samples’ length and width under uniaxial course wise elongation. A range of samples of rib 1×1, 2×2, 3×3, 4×4 and 5×5 knits, made of cotton, bamboo, polyacrylonitrile (PAN), wool/acrylic blend and wool yarn, were stretched with a tensile machine WDW-05M. In the process of stretching the width of each specimen was defined in the moments of extension by 50, 100, 150, 200, 250 and 300 per cent. It has been found that linear approximation can be applied to describe the dependence of specimen’s width on its relative course wise elongation. It was found that the stitch height/width ratio changes unevenly. In the beginning of the process of course wise stretching of a rib knitted structure, it does exist, such an interval, where an increase of the knit’s linear size along the courses occurs without a significant shrinkage in the wale wise direction. It is suggested to name the upper limit of this interval as “unidimensional extension limit” and define it as an extension of a standard (100×50mm) specimen, at which its width decreases by 10%. It was found as well that the value of this index significantly depends on the ribbing variation and much less on the type of raw materials

The resistance of the material to a change of its color characteristics during exposure to sunlight, rubbing and washing as domestic and laundry and other various ways are referred to as color fastness of dyes or pigments. In this research, 100% cotton and blended fabrics were dyed with fluorescent pigments i.e. Shining Flu Pink-F17 and Papillion Orange-FGRN in exhaust dyeing method. The improvement of color fastness properties, i.e. color fastness to washing, rubbing, perspiration and light were observed with the treatment of using antioxidants and UV-absorbers. There were eight samples of dyed fabrics (Four samples of 100% cotton knit fabric and four samples of 60/40 cottonpolyester blended fabrics) treated with 1% (v/v) of antioxidants i.e. Gallic acid, L-Ascorbic acid and UV absorbers i.e. 2-hydroxy-4 methoxy-benzophenone, 4-4 dimethoxy-benzophenone respectively. The treatment of antioxidant L-Ascorbic acid and UV absorber 4-4 dimethoxy-benzophenone provides satisfactory improvement of fastness properties than other antioxidants and UV absorbers. The results were mainly interpreted in terms of color strength, visual assessment of evenness and fastness ratings.
