Published: June 2024

Abstract
Protein-based drugs are a mainstay of modern medicine. In contrast to antibodies, most of these need highly individualized production processes which often limits their development. Here, we develop an immunoglobulin domain tag (i-Tag), which can be fused to any protein of interest. This tag is made of a linear arrangement of antibody light chain constant domains. It enhances expression as well as secretion of the fusion partner and allows for simple purification of several structurally and functionally distinct fusion proteins. Furthermore, it improves the biophysical characteristics of most fusion proteins tested, is inert, and does not compromise the fusion partners’ functionality. Taken together, the i-Tag should facilitate the development of biopharmaceuticals and diagnostic proteins otherwise lacking a common structural element.
Israeli Nonsense: humor, globalization and vegetables during the early nineties
Authors: Idels Ofer , Cohen Roni 
Published: June 2024

Abstract
Offering an inaugural analysis of Israeli Nonsense, this article explores humor, globalization, and Israeli identity since the early 1990s. Israeli Nonsense, a particular form of humor, emerged during Israel’s rapid shift towards neoliberal privatization and globalization. Influenced by the growing popularity of standup comedy and the rise of new commercial television channels, it became a distinctive humor style in an era marked by optimism and “normalization.” It quickly formed nostalgic classics, leaving a lasting impact on contemporary Israeli humor. Through interviews, newspaper excerpts, and sketch analysis, we identify five key attributes of Israeli Nonsense: (1) improvisation, (2) linguistic humor, (3) physical humor, (4) nostalgia, and (5) non-politicization. By challenging existing interpretations of 1990s Israeli culture and nonsense as “elitist” with anti-national and non-ideological tendencies, we highlight the popular manifestations of Israeli Nonsense to demonstrate that this distinct humor did not adopt a consciously critical and cynical stance towards society and culture but embodied an optimistic and empathetic attitude toward local identity in the age of globalization.
Prevalence and correlates of sexual intercourse under influence of alcohol among Thai adolescents: lessons from a nationwide school-based survey
Authors: Dadras Omid 
Published: June 2024

Abstract

Objectives
Having sex under the influence of alcohol is a risky behavior and this study explored its prevalence and correlates among school-going Thai adolescents.

Methods
The data from the 2021 Thailand Global School-based Student Health Survey (GSHS), including a nationally representative sample of students in grades 7–12th, was used to extract the relevant variables including demographic, psychosocial, substance use, and risky sex behaviors. Logistic regression was used to assess the odds of engaging in sex while intoxicated across the independent variables while accounting for age and sex differences.

Results
Approximately 30.45 % of respondents reported alcohol intoxication and 37.75 % reported engaging in sexual intercourse while intoxicated at least once. Older adolescents (>14 years), males, and those in 11 and 12 grades were more likely to engage in sexual intercourse while intoxicated. Psychosocial factors such as loneliness and anxiety-induced insomnia were associated with increased likelihood, particularly among females. Substance use, including marijuana and amphetamine use, as well as cigarette smoking, correlated with higher odds of engaging in sexual intercourse while intoxicated. Both genders who engaged in sex while intoxicated reported having multiple sexual partners, with males more likely to use condoms.

Conclusions
The intricate relationship between poor mental health, substance use, and risky sex behaviors along with their association with sex under alcohol influence emphasizes the need for a holistic approach to address the common risk factors and implement effective school-based screening strategies to identify the risk groups, educate them, and prevent the burden of risky sex under alcohol intoxication.
Effect of shielding gas composition and pulsed current frequency on geometry and nitrogen content of 304L austenitic stainless-steel welds
Authors: Hosseinzadeh Saeed , Goodarzi Massoud 
Published: June 2024

Abstract
This study investigated the effects of pulsed current frequency and shielding gas composition on the weld metal geometry and nitrogen content. Austenitic stainless-steel sheets were welded by gas tungsten arc welding using 0, 0.5, 1, 2, 5, and 10 vol.% of nitrogen gas in argon shielding gas and pulse frequencies of 40, 80, 120, 160, and 200 Hz. Weld sections were recorded using a stereomicroscope. Weld depth and cross-section of the weld metal were measured by ImageJ® software and their changes were recorded. Nitrogen analysis tests were performed on the weld metal and, the results were analyzed. Investigations revealed that by increasing the nitrogen content of the shielding gas up to 10 vol.%, the nitrogen content of the weld metal almost doubles at the maximum nitrogen level. This increase was more considerable at higher current frequencies. Also, by increasing the pulsed current frequency, the weld pool and the weld metal depth-to-width ratio increased to 37 % and 44 %, respectively, at the maximum level of shielding gas nitrogen. In addition, at the frequency of 200 Hz, increasing nitrogen led to an 86 % and 72 % increase in the weld pool and the weld aspect ratio, respectively.
Existence of multiple unbounded solutions for a three-point boundary value problems on an infinite time scales
Authors: Panigrahi Saroj , Das Sasmita 
Published: June 2024

Abstract
In this paper, we consider the second-order three point boundary value problem on time scales with integral boundary conditions on a half-line. We will use the upper and lower solution method along with the Schauder’s fixed point theorem to establish the existence of at least one solution which lies between pairs of unbounded upper and lower solutions. Further, by assuming two pairs of unbounded upper and lower solutions, the Nagumo condition on the nonlinear term involved in the first-order derivative, we will establish the existence of multiple unbounded solutions on an infinite interval by using the topological degree theory. The results of this paper extend the results of
Akcan and Çetin (2018), Akcan and Hamal (2014), Eloe, Kaufmann and Tisdell (2006), and generalize the results of Lian and Geng (2011). Examples are included to illustrate the validation of the results.
Ensemble Kalman inversion based on level set method for inverse elastic scattering problem
Authors: Huang Jiangfeng , Wang Quanfeng , Li Zhaoxing 
Published: June 2024

Abstract
We consider an ensemble Kalman inversion scheme for inverse elastic scattering problems in which the unknown quantity is the shape of the scatterer. Assume that the scatterer is a piecewise constant function with known value inside inhomogeneities. The level set method is described as an implicit representation of the scatterer boundary, with Gaussian random fields serving as prior to provide information on the level set functions. The ensemble Kalman filter method is then employed based on the level set functions to reconstruct the shape of the scatterer. We demonstrate the effectiveness of the proposed method using several numerical examples.
Serial block-face scanning electron microscopy of adherent cells on thin plastic substrate
Authors: Kauter Anne , Bürge Silvio , Klotz Christian , Laue Michael 
Published: June 2024

Abstract
Serial block-face (SBF) scanning electron microscopy (SEM) is used for imaging the entire internal ultrastructure of cells, tissue samples or small organisms. Here, we present a workflow for SBF SEM of adherent cells, such as Giardia parasites and HeLa cells, attached to the surface of a plastic culture dish, which preserves the interface between cells and plastic substrate. Cells were embedded in situ on their substrate using silicone microwells and were mounted for cross-sectioning which allowed SBF imaging of large volumes and many cells. A standard sample preparation and embedding protocol for thin section electron microscopy provided already sufficient resolution and image quality to visualize larger structures. To improve resolution and image quality of SBF imaging, we stepwise tested modifications of the protocol, such as the moderate increase of the heavy metal content of the sample. Modifications of the embedding by either the reduction of the resin layer (minimal embedding) or the addition of silver colloid to the resin were evaluated at high and low vacuum imaging conditions. The optimized sample preparation protocol is very similar to the standard preparation protocol for thin section electron microscopy, so that the samples can also be used for this application. The protocol applies a higher concentration of osmium tetroxide, a higher temperature for heavy metal incubation and an additional lead en bloc staining. In summary, the presented workflow provides a generic and adaptable solution for studying adherent cells by SBF SEM.
Determination of C-factor for conventional cultivation and soil conservation technique used in hop gardens
Authors: Kabelka David , Kincl David , Vopravil Jan , Krofta Karel , Kintl Antonín 
Published: June 2024

Abstract
The research presented in the article was focused on determining the C-factor for hops for conventional cultivation (CT) and soil conservation technique, which is based on the presence of cover crops (CC) in the inter-rows. The values of the soil loss ratio, which are the basis for the calculation of the C-factor, are also presented. The research activities were carried out between 2016 and 2023 and a field rainfall simulator was used for the measurements. Rainfall simulations were conducted at three developmental stages of CC. The results show a high C-factor value for CT (0.73), which indicates insufficient erosion control efficiency. In contrast, a C-factor of 0.16 was determined for the cover crop technique. This means that cover crops in the inter-rows of hop gardens can effectively reduce the risk of water erosion. The values reported in the article can be used as input parameters in various erosion models and equations to refine the subsequent calculation.
Convergence of 3D printing, scaffoldomics and bone regeneration: Designing new toughened biodegradable composites with weak interfaces
Authors: Cavelier S. , Hutmacher D. W. 
Published: June 2024

AbstractScaffold-guided bone regeneration (SGBR) is a rapidly developing field that aims to address the clinical challenges in reconstructive surgery. Combining ceramics with biodegradable polymers offers a wide range of physico-chemical properties, but their mechanical properties are far from the expectations. Nature offers examples of mineralized materials with excellent mechanical properties. This can be attributed to their unique architecture featuring soft polymeric interfaces that deflect propagating cracks. The present article depicts the role of soft interfaces on bone toughness, the governing equations of cracks propagating at interfaces, and provide guidelines for the design of medical grade composites for SGBR.

Published: June 2024

Aim. To carry out a retrospective analysis of the treatment outcomes of the patients who underwent liver resection with angioplasty facilitated by transplantation techniques. Materials and methods. The sample of cases was divided into four groups: liver resection with total vascular isolation of the liver, ante situm liver resection, hepatic artery and portal vein reconstruction, cardiopulmonary bypass resection. The analysis was focused on surgery features and treatment outcomes. Results. The study involved 29 patients. The performed interventions included 11 liver resections with total vascular isolation, 6 ante situm liver resections, 7 resections with angioplasty, and 5 cardiopulmonary bypass resections. 5 patients (17 %) developed complications that required reoperation. Within 90 days, 4 patients (14 %) died. For patients with malignant neoplasms, one-, three-, and five-year overall survival rates accounted for 84.4 %, 58.4 %, and 51.1 %; one-year event-free survival rate comprised 57.1 %, and three- and five-year event-free survival was 41.7 %.The study revealed no significant differences in the complication rates. The groups of ante situm liver resections and cardiopulmonary bypass resections significantly differed from the other groups by the higher incidence of tumor progression, invasion of adjacent organs, hemorrhagic complications, preoperative stay, and duration of cold perfusion of the liver. The cardiopulmonary bypass resections were noted to have higher duration of surgery, vascular isolation, heparin use, and the frequency of anticoagulant therapy before surgery. Conclusion. Liver resections with total vascular isolation, angioplasty and transplantation techniques are considered as the only possible treatment option for a number of patients. Further accumulation of results will reduce the risk of adverse outcomes.

Aim. To improve treatment outcomes for children with common bile duct cysts. Materials and methods. The study enrolled children with common bile duct cysts (n = 84) examined from January 2010 to November 2023. All patients underwent cyst excision, Roux-en-Y hepaticojejunostomy laparoscopically or from a minilaparatomy access. A comparative analysis of the treatment outcomes was carried out to select the optimal access. The timing of surgery, as well as early and late postoperative complications were analyzed. Results. The timing of surgery from the minilaparotomy access was shorter. Defecation in children of the minilaparotomy subgroup appeared 3 times earlier than in children after laparoscopic hepaticojejunostomy, largely due to earlier enteral load. A good treatment outcome was observed in 92 % of patients who underwent intervention from a minilaparotomy access compared to 52.2 % of patients who underwent laparoscopic surgery. Conclusion. Currently, laparoscopic access is a non-optimal method for treatment of children with common bile duct cysts. Minilaparotomy appears to be a promising surgical access in children and may be proposed as a standard for common bile duct cysts.

Aim. To study the causes and consequences of bile leakage in liver injury and determine the potential ways for its elimination. Materials and methods. The study involved a retrospective analysis of 204 liver injuries of various types. 26 % of cases were detected with isolated abdominal trauma, 74 % – with concomitant abdominal injury. According to the AAST grading scale, 15.7 % of patients got grade II liver injuries, 44.6 % – grade III, 34.3 % – grade IV, and 5.4 % – grade V. Since concomitant injuries predominated, surgical treatment was initially performed in the overwhelming number of cases. 14 % of cases received non-operative management. Results. The incidence of bile leakage amounted to 28.4 % for all liver injuries and reached 54.9 % for III–V grade injuries (AAST). Small bile leakage prevailed, while active leaking was observed in 36.2 %. Damage to peripheral parts of the biliary tract was noted in most cases (68 %). Conservative management of patients with small bile leakage associated with damage to peripheral parts of the biliary tract appeared successful in 48.5 % of cases. Endoscopic biliary drainage of bile ducts proved effective in case of active bile leakage and (or) injuries of the central bile ducts. Conclusion. Endoscopic biliary drainage of bile ducts is considered the most effective for elimination of active biliary leakage in the absence of biliary peritonitis and communication of biliary tract with pleural cavity.

Published: June 2024

The popularity of mobile gaming is increasing globally, fueled by technological advancements, high-quality smartphones with gaming features, and widespread internet access. A large number of young people and also children are mainly involved in different types of mobile gaming, primarily online mobile gaming, which is a matter of concern for society. This addiction leads to various psychological issues, including mental health problems, loneliness, introversion, insomnia, and a lack of self-control. Bangladesh’s lack of public mental health facilities exacerbates this challenge, particularly in rural areas. To address this issue, we have developed a machine learning model to predict the level of mental health issues faced by Bangladeshi urban children due to gaming addiction. A total of 1996 data were collected from urban parents about their children's gaming activities and categorized them as 'Serious,' 'Partial,' and 'Normal.' The dataset was then split into a 70:30 ratio for training and testing purposes. K-Nearest Neighbors (KNN), Support Vector Machine (SVM), Multinomial Naïve Bayes, & Random Forest were applied as the machine learning approaches for prediction. Here, the Support Vector Machine gives good accuracy (92.75%), and other classifiers have different accuracy. The research highlights the significance of addressing gaming addiction in children and the potential of machine learning technology in predicting mental health issues, particularly in the absence of public mental health services. The study concludes by proposing the expansion of the research to include smartphone and mobile gaming addiction among Bangladeshi rural children and ensure a holistic approach to tackling the broader issue of technology-related addiction.

Authors: Skinner-Osei Precious 
Published: June 2024

Background:The COVID-19 pandemic introduced unprecedented challenges to individuals involved in the justice system, particularly African Americans, who have borne a significant burden of its consequences. To better understand the circumstance, this article presents follow-up data 2 years after the pandemic’s onset from Skinner-Osei’s 2023 study, “The Impact of COVID-19 on Justice-Involved African Americans.”Methods:The study employed a phenomenological approach to examine the experiences of justice-involved African Americans in navigating challenges related to recidivism, probation/parole, housing, employment, and family during and after the pandemic. The data were analyzed using the reflexive thematic analysis process.Findings:The original study had 25 participants, and 12 were in the follow-up. The data obtained from both studies underscore the necessity of further research into the enduring impacts of COVID-19 on African Americans involved in the justice system.Conclusion:Given the disproportionate impact of the pandemic on this population, it is critical to explore the long-term ramifications of the virus and its aftermath so that we can better understand the multifaceted challenges facing African Americans in the justice system and develop evidence-based solutions that mitigate the impact of COVID-19 on this vulnerable group.
