Effect of surfactant type on the dyeability and color resistance of semi-permanent basic hair dye
Authors: Yun Kyeoungsook , Ahn Cheunsoon 
Published: January 2023

AbstractBasic Brown 16 pigment and three types of surfactants were used to prepare the cationic, nonionic, and anionic basic hair dyes. White hair and bleached hair were dyed using the three basic hair dyes and were shampooed 10 times using acidic, neutral, and alkaline shampoos prepared in the study. White hair and bleached hair dyed with the anionic basic hair dye resulted in a lower L*, a*, b* values and lower K/S values compared to the hair dyed with the cationic and nonionic basic hair dyes and the results were statistically significant at α = 0.05. Hair dyed with the anionic basic hair dye showed significantly higher ΔL*, Δa*, Δb*, and ΔE*ab values after 10 times of shampooing than those dyed with cationic and nonionic basic hair dyes (α = 0.05), indicating a lower color resistance for the anionic basic hair dye. Color difference after shampooing was significantly higher when alkaline shampoo was used (α = 0.05). Overall, the color difference after shampooing occurred more by the type of dye than by the type of shampoo.
“We're going on a virtual trip!”: a switching-replications experiment of 360-degree videos as a physical field trip alternative in primary education
Authors: Garcia Manuel B. , Nadelson Louis S. , Yeh Andy 
Published: January 2023

AbstractField trips are steadily declining due to limited funding, time constraints, safety concerns, and other logistical issues. Many schools are resorting to a virtual field trip (VFT), especially when education is disrupted due to public health concerns, natural disasters, or other unforeseen significant events. Virtual reality as a common form of VFT is likely not an option for many schools due to cost and other barriers. The purpose of our study was to explore the potential of going in a VFT using 360-degree (360°) videos as an alternative to a physical field trip in primary education. We recruited third-grade pupils (aged 8–9) from two private elementary schools to experience VFTs using 360° videos (360V) and regular videos (REGV). Using a switching-replications experimental design, we compared their content recall (assessment tests) and VFT experience (attitude, perceived usefulness, involvement, inquiry, video engagement, and virtual guide) across four-time points. Our results show that the increase in content recall scores of 360V groups after VFTs was consistently higher compared to REGV groups at all time points, although it was only significant in one quarter. We also found pupils’ video engagement, involvement, and attitude as significant factors in their VFT experience. These results call attention to a possible implementation of VFTs and continue the long-standing tradition that has been acknowledged as a student-centered, interactive instructional method.

Published: January 2023

AbstractFree-recall paradigms have greatly influenced our understanding of memory. The majority of this research involves laboratory-based events (e.g., word lists) that are studied and tested within minutes. This literature shows that adults recall events in a temporally organized way, with successive responses often coming from neighboring list positions (i.e., temporal clustering) and with enhanced memorability of items from the end of a list (i.e., recency). Temporal clustering effects are so robust that temporal organization is described as a fundamental memory property. Yet relatively little is known about the development of this temporal structure across childhood, and even less about children’s memory search for real-world events occurring over an extended period. In the present work, children (N = 144; 3 age groups: 4–5-year-olds, 6–7-year-olds, 8–10-year-olds) took part in a 5-day summer camp at a local zoo. The camp involved various dynamic events, including daily animal exhibit visits. On day 5, children were asked to recall all the animals they visited. We found that overall recall performance, in terms of number of animals recalled, improved steadily across childhood. Temporal organization and recency effects showed different developmental patterns. Temporal clustering was evident in the response sequences for all age groups and became progressively stronger across childhood. In contrast, the recency advantage, when characterized as a proportion of total responses, was stable across age groups. Thus, recall dynamics in early childhood parallel that seen in adulthood, with continued development of temporal organization across middle to late childhood.
Reviewing next of kin regrets in surgical decision-making: cross-sectional analysis of systematically searched literature
Authors: Maillard Julien , Beckmann Tal S. , Tramèr Martin R. , Elia Nadia 
Published: January 2023

Abstract
Background
Decision-making concerning relatives undergoing surgery is challenging. It remains unclear to what extent implicated next of kin eventually regret their decisions and how this regret is assessed. Our aim was to systematically review the literature on decisional regret of next of kin and to describe the assessment tools used and the surgical populations studied.

Methods
We included interventional or observational, quantitative or qualitative studies reporting the measurement of decisional regret of next of kin concerning relatives undergoing surgery. We searched a variety of databases without restriction on publication year. We assessed the quality of reporting of quantitative studies using the NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies and of qualitative studies using the Critical Appraisal Skills Program Checklist.

Results
Thirteen cross-sectional, five prospective cohorts and five qualitative studies matched our inclusion criteria. In 18 studies (78%), patients were children, in five (22%), young or middle-aged adults. No study included elderly or frail patients. Thirteen studies (57%) used the original Decision Regret Scale which was validated for patients, but not for next of kin. Only 3 of the 18 (17%) quantitative studies and only one of the 4 (25%) qualitative studies were rated as “good” in the quality assessment.

Conclusion
None of the retrieved studies used validated tools to assess the decisional regret of next of kin and none of them examined this issue in elderly or frail surgical patients.

Published: January 2023

Abstract
Background
Implants immediately loaded full-arch prosthesis in maxilla is always a challenge, especially when the zone 2 is extremely defected. To achieve a satisfying result, different therapeutic alternatives have been proposed, such as zygomatic implant, pterygoid implant; however, precise surgical skills limited its application.

Case presentation
This study reported a case that an edentulous patient was treated with a new technique, two axial implants and four tilted implants supporting an immediate fixed denture, extruding the cortical bone of the anterior wall of the maxillary sinus to establish the primary stability.

Conclusions
Two-year follow-up proves that it is a viable choice. Meanwhile, a reliable method for its saving time and money and low level of discomfort for patients is presented.
Surgical correction of polymelia in the perineal region of a 2-day-old indigenous bovine calf: a case report from Bangladesh
Authors: Munif Mohammad Raguib , Safawat Mst. Sanjida , Hannan Abdul 
Published: January 2023

Abstract
Background
Polymelia is an occasional and congenital malformation in bovine calves, characterized by the presence of single or multiple accessory limb(s) at various body regions, which are often called the supernumerary limb(s). One of these defects is known as pygomelia, where the additional limb is attached to the pelvis within the perineal region. This study describes such a case along with surgical management.

Case presentation
A 2-day-old indigenous bovine female calf of 22.7 kg BW was presented with an additional and non-functional fifth limb at the perineal region. The ectopic fifth limb was smaller in size than the other four normal limbs and was in a flexible hanging position. Other than this, the animal was apparently normal with a short and contracted tail. Clinical examinations involving the extension and flexion of the abnormal limb revealed no deep bony attachment/articulation with the pelvic girdle or the caudal spine. The curled tail having an S-shaped base indicated the skeletal defects in the caudal spine. Electrosurgery was performed under deep sedation with regional as well as local anesthesia, which exposed that the limb was internally seated into deep gluteal muscle layers with the attachments of fibrous connective tissues and cartilage to its proximal bony head and located partially to the left lateroventral extremity of the perineum without any direct involvement in the bony pelvis. Surgical excision was done to remove the supernumerary limb, and the wound was closed routinely. Postoperatively, the animal was provided with supportive medications for early healing and recovery. After 2 weeks of surgery, the calf completely recovered without any complications. The contracted tail and spine were left unaffected as no initial surgical maneuver was done due to the early age of the calf and would be considered for further long-term treatment options upon the growth and development with age.

Conclusions
Pygomelia of bovine calves is one of the rare congenital defects that can be found along with other developmental anomalies. However, this defect can be successfully corrected by surgical approaches following intensive postoperative care and management.

Abstract

Background
Few real-world examples exist of how best to select and adapt implementation strategies that promote sustainability. We used a collaborative care (CC) use case to describe a novel, theory-informed, stakeholder engaged process for operationalizing strategies for sustainability using a behavioral lens.

Methods
Informed by the Dynamic Sustainability Framework, we applied the Behaviour Change Wheel to our prior mixed methods to identify key sustainability behaviors and determinants of sustainability before specifying corresponding intervention functions, behavior change techniques, and implementation strategies that would be acceptable, equitable and promote key tenets of sustainability (i.e., continued improvement, education). Drawing on user-centered design principles, we enlisted 22 national and local stakeholders to operationalize and adapt (e.g., content, functionality, workflow) a multi-level, multi-component implementation strategy to maximally target behavioral and contextual determinants of sustainability.

Results
After reviewing the long-term impact of early implementation strategies (i.e., external technical support, quality monitoring, and reimbursement), we identified ongoing care manager CC delivery, provider treatment optimization, and patient enrollment as key sustainability behaviors. The most acceptable, equitable, and feasible intervention functions that would facilitate ongoing improvement included environmental restructuring, education, training, modeling, persuasion, and enablement. We determined that a waiting room delivered shared decision-making and psychoeducation patient tool (DepCare), the results of which are delivered to providers, as well as ongoing problem-solving meetings/local technical assistance with care managers would be the most acceptable and equitable multi-level strategy in diverse settings seeking to sustain CC programs. Key adaptations in response to dynamic contextual factors included expanding the DepCare tool to incorporate anxiety/suicide screening, triage support, multi-modal delivery, and patient activation (vs. shared decision making) (patient); pairing summary reports with decisional support and yearly onboarding/motivational educational videos (provider); incorporating behavioral health providers into problem-solving meetings and shifting from billing support to quality improvement and triage (system).

Conclusion
We provide a roadmap for designing behavioral theory-informed, implementation strategies that promote sustainability and employing user-centered design principles to adapt strategies to changing mental health landscapes.
Cardiac dysfunction in a cohort of biopsy proven nonalcoholic steatohepatitis in comparison to nonalcoholic fatty liver
Authors: Varghese Jijo , Devadas Krishnadas , Vinayakumar Neeraj , Nahaz Nibin , Hareendran Atul , Oommen Tharun Tom , George Bony 
Published: January 2023

Abstract
Introduction
NAFLD (non-alcoholic fatty liver disease) is increasing worldwide. Inflammation, fibrosis, and steatosis are the three components of NAFLD. Cardiac events are the most common cause of death in NAFLD. It is believed that there is an association between the inflammatory component of NAFLD and cardiac dysfunction. The gold standard for diagnosis of NAFLD is liver biopsy. Based on histology, NAFLD is categorized into two, nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH). As biopsy is an invasive procedure, studies comparing cardiac dysfunction in NAFL and NASH are few. The aim of our study is to compare cardiac dysfunction in patients with NAFL and NASH.

Materials and method
This is a cross-sectional study in which all patients who were biopsy proven for NAFLD without stage 4 fibrosis were included. Cardiac dysfunction in these patients was assessed by 2 D ECHO.

Results
Out of the 92 patients, 52 were males and 40 were females (53.5 vs 46.5 %). Among these patients, 48 had NAFL, whereas 48 had NASH. Among the variables analyzed for the study SGOT, SGPT, ALP, Ferritin, ANA, TSH, LVEF, LA diameter, E/e, NAS score, lobular inflammation, ballooning, and steatosis statistically correlated with cardiac diastolic dysfunction. Majority of the patients with NASH had cardiac dysfunction (32/44) while only a few patients with NAFL (4/48) had cardiac dysfunction (p value = 0.002). Among the variables that can cause diastolic dysfunction, i.e., coronary artery disease, dyslipidemia, diabetes mellitus, and hypertension, only diabetes mellitus had an independent association. By binary logistic regression, it was seen that NASH was an independent risk factor for predicting cardiac dysfunction.

Conclusion
The prevalence of cardiac dysfunction is more in NASH than NAFL in patients with NAFLD. NASH is an independent risk factor for cardiac dysfunction. There is no correlation between fibrosis and diastolic dysfunction.

Abstract
Background
Diabetes mellitus is one of the leading causes of morbidity and mortality globally. Although synthetic hypoglycemic agents are commonly used to manage this disorder, such medications, besides being unable to cure the disease, are expensive and associated with side effects. Conversely, medicinal plants have emerged as effective, safe and affordable alternative treatments. Boswellia dalzielii plant has been reported to possess ethnomedicinal properties for the treatment of various health conditions; however, scientific studies exploring this plant as antihyperglycemic agent are still limited. Thus, this study evaluated the antihyperglycemic activity of aqueous stem bark extract (ASBE) of B. dalzielii in alloxan-induced diabetic Wistar albino rats.

Methods
Phytochemical screening of the ASBE of B. dalzielii was conducted. Twenty male Wistar albino rats weighing 100–150 g divided into 4 groups (A–D) of five rats were used for the study. Group A served as the normal control and received neither ASBE of B. dalzielii nor glibenclamide. The treatment for the other three groups was as follows: Group B, 10 mg/kg of glibenclamide (diabetic control); Group C, 500 mg/kg ASBE of B. dalzielii; and Group D, 1000 mg/kg ASBE of B. dalzielii. Treatments were administered orally every 24 h for a period of 2 weeks. Blood glucose level and body weight were evaluated at weeks 0, 1 and 2. Histomorphological features of the rats’ pancreas in all the groups were compared.

Results
The phytochemical analysis revealed the presence of alkaloids, saponins, tannins, cardiac glycosides, flavonoids, carbohydrates, steroids and triterpenes. The two different doses of the plant extract significantly reduced blood glucose level at weeks 1 and 2 (all p < 0.05), with the 1000 mg/kg dose demonstrating a greater reduction compared with glibenclamide at week 2 (p = 0.014). However, only the 500 mg/kg dose led to restoration, albeit slight, of the pancreatic islet cells.

Conclusion
This study suggests that B. dalzielii plant exhibits a potent antihyperglycemic activity evidenced by reduced blood glucose levels and slight restoration of pancreatic islet cells. This plant could be, therefore, considered in the treatment of diabetes mellitus.

Tuning attraction and repulsion between active particles through persistence
Authors: Metson M. J. , Evans M. R. , Blythe R. A. 
Published: January 2023

Abstract
We consider the interplay between persistent motion, which is a generic property of active particles, and a recoil interaction which causes particles to jump apart on contact. The recoil interaction exemplifies an active contact interaction between particles, which is inelastic and is generated by the active nature of the constituents. It is inspired by the “shock” dynamics of certain microorganisms, such as Pyramimonas octopus, and always generates an effective repulsion between a pair of passive particles. Highly persistent particles can be attractive or repulsive, according to the shape of the recoil distribution. We show that the repulsive case admits an unexpected transition to attraction at intermediate persistence lengths, that originates in the advective effects of persistence. This allows active particles to fundamentally change the collective effect of active interactions amongst them, by varying their persistence length.
Protective role of trehalose in the Namib desert ant, Ocymyrmex robustior
Authors: Perez Rémy , Aron Serge 
Published: January 2023

ABSTRACT
Over recent decades, increasing attention has been paid to how low-molecular-weight molecules affect thermal tolerance in animals. Although the disaccharide sugar trehalose is known to serve as a thermal protectant in unicellular organisms, nothing is known about its potential role in insects. In this study, we investigated the effect of trehalose on heat tolerance in the Namib desert ant, Ocymyrmex robustior, one of the most thermotolerant animals found in terrestrial ecosystems. First, we tested whether a trehalose-supplemented diet increased worker survival following exposure to heat stress. Second, we assessed the degree of protein damage by comparing protein aggregation levels for trehalose-supplemented workers and control workers. Third, we compared the expression levels of three genes involved in trehalose metabolism. We found that trehalose supplementation significantly enhanced worker heat tolerance, increased metabolic levels of trehalose and reduced protein aggregation under conditions of heat stress. Expression levels of the three genes varied in a manner that was consistent with the maintenance of trehalose in the hemolymph and tissues under conditions of heat stress. Altogether, these results suggest that increased trehalose concentration may help protect Namib desert ant individuals against heat stress. More generally, they highlight the role played by sugar metabolites in boosting tolerance in extremophiles.

Published: January 2023

Objectives: To determine the frequency of clinical anger, adverse childhood experiences, self-esteem, and their mutual relationship among undergraduate medical and sociology students.
Methods: In this descriptive cross-sectional study, data from 400 undergraduate medical and sociology students was collected from the Northwest School of Medicine, Peshawar, and the sociology department of the International Islamic University, Islamabad, from July to September 2021. A self-administered questionnaire incorporating a Clinical Anger Scale (CAS), Adverse childhood experience (ACE) scale and Rosenberg self-esteem (RSE) scale was utilized for data collection. Descriptive statistics, ANOVA and logistic regression model were executed to perform data analysis using SPSS.
Results: The mean CAS score was 19.65 ± 13.23 suggesting that 60.2% of the participants experienced mild to severe degrees of clinical anger. Females were experiencing more anger issues than males (64% vs 54%, p = 0.040) RSE scale showed that 72.8% of the participants had low self-esteem with a mean score of 12.70 ± 5.43. Besides, 51.5% of the participants had at least one type of adverse childhood experience while 15.8% of the sample population reported being sexually abused in childhood. Significant correlation was found between CAS and age, ACEs and RSE score (p = <0.01). The logistic regression model also suggested that the prevalence of anger was higher in individuals with ACEs (OR = 1.29, 95% CI: 1.12, 1.14, p = <0.001) and low self-esteem (OR = 1.15, 95% CI: 1.09, 1.22, p = <0.001).
Conclusion: The high frequency of clinical anger necessitates the implementation of periodic screening across all universities. Keeping in mind the problem of low self-esteem and the history of ACEs, there is an urgent need for the development of strategies to preserve and improve the mental well-being of the young generation.
