Authors: Kamilçelebi Hatime
Published: February 2024

Sosyoekonomik statü (SES) farklılığının farklı duygu ve davranışlar üzerine yoğunlaştığını belirten çalışmalar son yıllarda hızla artmaktadır. Düşük ve yüksek SES’e sahip bireylerin bazı duygu ve davranışlarının statüleriyle yakından ilişkili olduğu belirtilmektir. SES’teki farklılık nedeniyle belli duygu ve davranışlar insanlar tarafından daha az veya daha çok deneyimlenmektedir. SES farkı nedeniyle oluşan bu
duygu ve davranış farklılıkları çeşitli politikalarla dengelenebilmektedir. Bu araştırmanın amacı; SES farkı nedeniyle oluşan duygu ve davranış farklılıklarını ortaya çıkarmak ve SES farkı nedeniyle insanların duygu ve davranış deneyimlerindeki dengesizliği gidermek için teşvik edici politikalar önermektir. Çalışmada ilk olarak, düşük ve yüksek SES’e sahip bireylerin deneyimledikleri olumlu duygular ve bunların kendilerine ve başkalarına odaklı davranışlara yol açması literatürdeki deneyler yoluyla incelenecektir. İkinci olarak, yardımseverlik şemsiyesi altındaki bir davranış olan alturistik davranış ve benmerkezciliğin merkezde olduğu narsisistik kişilik özelliklerinin düşük ve yüksek SES ile ilişkisi literatürdeki deneyler ve anket sonuçlarıyla açıklanıp karşılaştırılacaktır. Son olarak, yüksek ve düşük SES’in etik olmayan davranışlarla ilişkisi literatürdeki çeşitli deney bulgularıyla analiz edilecektir. Çalışma bu yönüyle eşitsizliğin azaltılması için bireylerin duygularını daha iyi anlamaya ve bu yönde politikalar yapılabilmesi için gelecekte yapılacak araştırmalara katkı sağlayacaktır.

Authors: Gabrielson Paul W. , Smith Anna Claire , Bruno John F. , Vision Todd J. , Brandt Margarita
Published: February 2024

DNA sequences were obtained from 32 blade-forming Ulva specimens collected in 2018 and 2019 from four islands in the Galápagos Archipelago: Fernandina, Floreana, Isabela and San Cristóbal. The loci sequenced were nuclear encoded ITS and plastid encoded rbcL and tufA, all recognized as barcode markers for green algae. Four species were found, Ulva adhaerens, U. lactuca, U. ohnoi and U. tanneri, all of which have had their type specimens sequenced, ensuring the correct application of these names. Only one of these, U. lactuca, was reported historically from the archipelago. Ulva adhaerens was the species most commonly collected and widely distributed, occurring on all four islands. Previously known only from Japan and Korea, this is the first report of U. adhaerens from the southeast Pacific Ocean. Ulva ohnoi was collected on three islands, Isabela, Floreana, and San Cristóbal, and U. lactuca only on the last two. Ulva tanneri is a diminutive, 1–2 cm tall, high intertidal species that is easily overlooked, but likely far more common than the one specimen that was collected. This study of blade-forming Ulva species confirms that a concerted effort, using DNA sequencing, is needed to document the seaweed flora of the Galápagos Archipelago.

Published: February 2024

Objectives

Monocyte distribution width (MDW) is a new biomarker used as an early indicator of sepsis (ESId). It is often aids in the identification of patients who may develop sepsis. This study aims to establish the MDW reference interval (RI) within the healthy population of blood donors using EDTA-K2 as anticoagulant. Many hospitals use this biomarker as a means of identifying patients who present to the hospital with sepsis.

Methods

A total of 274 samples obtained from healthy donors were analyzed. MDW measurements were taken within 2 h post-extraction. The RI was estimated using various statistical methodologies, including the recommended CLSI EP28-A3c guideline, non-parametric and robust methods, along with the Harrell-Davis bootstrap method applied to the entire sample.

Results

The RI estimated through non-parametric method was 14.77 CI90 % (14.36–14.97)–21.13 CI90 % (20.89–21.68); RI using the robust method was 15.64–19.05 and RI using the Harrell-Davis bootstrap method was 14.73 CI90 % (14.53–14.92)–21.14 CI90 % (20.88–21.40).

Conclusions

Based on clinical applicability, we recommend utilizing the RI derived from the non-parametric method, aligning with the CLSI recommendations. Furthermore, we consider that our results can be taken as a reference in other laboratories that serve a population similar to our study cohort.

Authors: Nourouzpour Mohammad Mehdi , Habibi Alireza , Amiri Fariba
Published: February 2024

The kinetic study on sophorolipids (SLs) production by Candida catenulata from glucose, raw sunflower soapstock was investigated at different initial concentrations ranging from 0 to 100 g L−1. The Monod model with a maximum specific growth rate (μ
max) of 0.0167 h−1 and half-saturation coefficient (K

S
) of 6.91 g L−1 best described the cell growth kinetics of C. catenulata on glucose. The best-fitted constants of the Monod model for raw sunflower soapstock were μ
max = 0.0157 h−1 and K

S
 = 16.01 g L−1. Determination of Luedeking-Piret constants indicated SLs mainly produced as an associated growth product in the systems. Dynamic features of the fermentation were modeled using the obtained constants and results showed the prediction power of the developed model in describing the behavior of the process. Also, a modified kinetic model was developed for the dynamic modeling of the dual carbon sources system.
Häuser am Hardangerfjord als Orte deutsch-norwegischer Kulturkontakte: Bertha Rohlsen, Karl Schmidt-Rottluff und Bess Mensendieck in Lofthus
Authors: Vogel Carolin
Published: February 2024

Due to its impressive nature and culture, the Hardanger region was a well-known and popular destination for Germans at the beginning of the 20th century. In the small village of Lofthus, art collector Bertha Rohlsen and gymnastics pioneer Bess Mensendieck even moved into their own summer homes. The expressionist painter Karl Schmidt-Rottluff was also a guest there and created images of the North that broke with traditional ways of seeing. This article examines the cultural contacts between people and landscape as well as the different kinds of cultural transfers that were made possible by the experience of space.
Das ,Ich‘, das ,Sie‘ und das ,Du‘ in Ernst Jüngers norwegischen Reisetagebuch Myrdun (1943)
Authors: Hansen Simon
Published: February 2024

In the sixth volume of Min kamp, Karl Ove Knausgård focuses on the European male generation that was significantly shaped by World War I. Knausgård also mentions the Lieutenant and later author Ernst Jünger (1895–1998), whose early autobiographical texts show only a perception of the self – but not a perception of the other. Based on Knausgård’s observation, this article examines to what extent a shift in perspective can be observed in Jünger’s travel literature, which was written during his time in Romsdal (Eidsbygda). This genre provides a promising subject for investigation, as writing about the other requires the physical presence of the other in direct confrontation.
„So muß Loki gelacht haben“: Zum Einfluss nordischer Mythologie auf Arno Schmidts Juvenilia
Authors: Buck Nikolas
Published: February 2024

Arno Schmidt is one of the most thoroughly researched German post-war authors. However, there is a significant gap with regard to his stationing in Øverås, Norway, as part of the German occupation troops during the Second World War. This applies not only to Schmidt’s experiences in Norway, but also to the influence of this period on his literary work. Accordingly, I will pursue the question of how Schmidt used his ’Norwegian years’ in his literary work. In particular, I will consider the influence of Nordic mythology on the group of the so-called “Juvenilia”, four of which originated in Norway.
Imaging of cylindrical inhomogeneites in a parallel plate waveguide with reverse time migration method
Authors: Yelkenci Tanju
Published: February 2024

While reverse time migration (RTM) algorithm is commonly used in geophysical explorations, this paper addresses the RTM imaging procedure for reconstructing of lossy dielectric discontinuities in a planar waveguide using electromagnetic waves at a single frequency. The direct problem of the related configuration is solved via method of moments (MoM) to produce the synthetic scattered data to be used in RTM. The achievements of the method are examined and verified by including different numerical examples. It is shown that the RTM approach can be used as an alternative imaging methodology in parallel plate waveguide problems.

Published: February 2024

In this work we have generated cattle-derived chimeric ultralong CDR-H3 antibodies targeting tumor necrosis factor α (TNF-α) via immunization and yeast surface display. We identified one particular ultralong CDR-H3 paratope that potently neutralized TNF-α. Interestingly, grafting of the knob architecture onto a peripheral loop of the CH3 domain of the Fc part of an IgG1 resulted in the generation of a TNF-α neutralizing Fc (Fcknob) that did not show any potency loss compared with the parental chimeric IgG format. Eventually, grafting this knob onto the CH3 region of adalimumab enabled the engineering of a novel TNF-α targeting antibody architecture displaying augmented TNF-α inhibition.

Published: February 2024

In the present study, the efficacy of low-cost biosorbent obtained from walnut shells for the removal of AFB1 was examined. The characterization of the biosorbent was investigated using SEM, EDS, FTIR, XRD, and pHpzc. Maximum removal (90.5 %) was achieved using 100 mg/mL of biosorbent, pH 7.0 at 45 °C for 45 min with 100 ng/mL of AFB1. The biosorbent’s adsorption capacity was found to be 178.9 mg/g as calculated using the Langmuir isotherm and assumption of monolayer AFB1 adsorption with homogenously dispersed adsorption positions on the biosorbent exterior. The kinetic data indicated the fast AFB1 uptake on biosorbent and followed the pseudo-second-order model. The thermodynamic factors revealed that the adsorption process is viable, spontaneous and endothermic. Furthermore, slight decrease in AFB1 adsorption was observed after repeating the adsorption–desorption process for 5 times. In conclusion, the obtained biosorbent is an economically, eco-friendly and promising material for the removal of AFB1.

The Status and Aspects of Construction of Seowon and Sawoo in Jeonbuk after the abolition of Seowon in the 19th Century
Authors:   Institute of Korean Cultural Studies Yeungnam University, Lee Sun-Ah
Published: February 2024

Daewongun, who had seized power upon the accession of King Gojong, ordered the destruction of Seowon in 1868 and promoted a policy to destroy more than 600 Seowon, leaving only 47. However, many of the destroyed Seowon and Sawoo had been rebuilt after Japanese colonial era and liberation.
165 of Seowon and Sawoo are estimated to be built in Jeonbuk, of which 96 were rebuilt except the unbroken Museongseowon.
Between 1868 and 1910, 19 places were rebuilt and 18 places were rebuilt during the Japanese colonial period. After liberation, 59 places were restored, and 61.4% of the rebuilt Seowon and Sawoo were built after liberation. In Short, the reconstruction of Seowon and Sawoo in the mid-20th century, more than 100 years after the destruction, is thought to have great implications for grasping the status and meaning of Seowon and Sawoo in the region.
From this point of view, it is necessary to closely examine the reconstruction and establishment of Seowon in Namwon, Imsil, and Sunchang. Namwon is the place where Seowons were built the most in Jeonbuk before the decree was issued. Imsil, which shared the border with Namwon, was the secon d largest n umber. There are 53 of 165 Seowon s built in Namwon and Imsil, accounting for 32.1%. However, the rate of reopening Seowon here is the lowest.
In particular, if Sun chan g, which has n o rebuilt Seowon , is in cluded, it is only 16.6%, which is below the average of ‘Im-Sun-nam’(Imsil, Sunchang, Namwon). This rate of reconstruction is remarkable when compared to regions exceeding 75% such as Jangsu, Jinan, Iksan, Gimje, Gunsan, and Gochang. By paying attention to these regional deviations, it is expected that the locality of the 20th century will be grasped by studying the group which led to rebuild Seowon.
After Japanese colonial era and liberation, newly built Seowons were also built in Gochang, Jeongeup, Jinan, Gimje, and Iksan, where reconstruction rates were high, while Namwon and Imsil, which had low reconstruction rates, were also poorly established. If research on these trends and deviations is continued from the perspective of local history, it will be possible to reveal the times reflected in Seowon and Sawoo, which were reconstructed or newly established in the 20th century, and to present the current role of Seowon in the context of continuity.
17th Century the Gang-woncheong(江原廳)’s Tribute P rocurement and Financial Management P olicy
Authors:   Institute of Korean Cultural Studies Yeungnam University, Jeon SangWuk
Published: February 2024

In the second year of King Injo’s reign(1624), the Gangwon-do Daedong Act was implemented. As a result, the Gang-woncheong(江原廳) became a key institution in the procurement of tribute. However, the Gang-woncheong(江原 廳) had difficulties in operating due to insufficient land area and excessive tribute burden. As a result, the Gang -woncheong(江原廳) paid tribute prices differently depending on whether the harvest was good or bad, or paid a lower price. This method of paying tribute prices was revised to a flat-rate payment method during the integration process with the Hoseocheong(湖⻄廳).
The outbreak of famine in the late 17th century affected the operation of the Gang-woncheong(江原廳). At the time, the Gang- woncheong(江原廳) was in such serious financial difficulty that it could not repay the borrowed resources from other institutions. Due to this, the Gangwon Office sought a fiscal security policy. First, a plan to increase revenue was attempted. This led to the implementation of Gichug-yangjeon(己丑量田). However, as the amount of Daedong tax was reduced by 2 to 4 heads, central repayment portion actually decreased. also attempted to reduce expenditures. However, expenditures actually increased due to the temporary burden of recovering tribute and the temporary burden of fishing in the Yeongdong(嶺東) region. In addition, it was not easy to reduce the tribute price in a situation where the price of tribute was set low at the beginning of the Gangwon-do Daedongbeobt. As such, the Gang-woncheong(江原廳)'s fiscal policy did not achieve any significant results. As a result, it became a regular practice for Gangwon Office to receive tribute support from the Honamheong(湖南廳).

Gomes, M, Fitas, A, Santos, P, Pezarat-Correia, P, and Mendonca, GV. Validation of a single session protocol to determine the load-velocity profile and one-repetition maximum for the back squat exercise. J Strength Cond Res 38(6): 1013–1018, 2024—We investigated whether a single session of absolute incremental loading is valid to obtain the individual load-velocity profile (LVP) and 1 repetition maximum (1RM) for the free-weight parallel back squat. Twenty strength-trained male subjects completed 3 testing sessions, including a baseline 1RM session and 2 LVP sessions (LVPrel based on incremental relative loads and LVPabs based on absolute load increments until 1RM). The 1RM load was compared between the baseline and LVPabs. The load at zero velocity (load-axis intercept [L0]), maximal velocity capacity (velocity-axis intercept [V0]), slope, and area under the load-velocity relationship line (Aline) were compared between the LVPrel and LVPabs using equivalence testing through 2 one-sided t-tests. Measurement accuracy was calculated using the absolute percent error. The 1RM measured at baseline and LVPabs was equivalent and presented a low absolute percent error (1.2%). The following LVP parameters were equivalent between LVPrel and LVPabs: 1RM, L0, and Aline because the mean difference between sessions was close to zero and the Bland-Altman limits of agreement (1RM:5.3 kg; L0:6.8 kg; Aline: 9.5 kg·m−1·s−1) were contained within the a priori defined ± equivalent margins (5% for 1RM and L0 and 10% for Aline). The aforementioned variables presented a low absolute percent error. However, slope and V0 were not equivalent between sessions. In conclusion, a single session of absolute incremental loading is a valid approach to obtain the L0 and Aline of the individual LVP and 1RM, and can be used to efficiently track the magnitude of neuromuscular adaptations throughout the training cycles for the free-weight back squat.
Local Instability and Deformation Control of Steel Roof of Factory Building in a Smart City
Authors: Liu Kai , Xu Liang , Wang Shengyan , Han Xurui
Published: February 2024

The traditional control methods of instability and deformation of steel structure neglect the analysis of its natural vibration characteristics, which lead to the poor effect of hysteretic vibration of steel structure nodes, and the stability optimization of steel structure is not ideal. Therefore, a new method to control the local instability and deformation of the steel roof is proposed. According to the steel structure composition of the upper door rigid frame and the connection mode of the frame beam and column, the roof steel structure characteristics of the workshop are analyzed. Multi-order natural frequency method is used to obtain the cumulative modal mass contribution rate of steel structure and analyze the natural vibration characteristics of steel structure. Based on the characteristics of natural vibration and element transfer matrix, the local instability control method of roof steel structure is designed. Simulation of strong vibration, using space analysis of tall-building with wall-elements (SATWE) software analysis of strong vibration under elastic load state, to obtain the external deformation of steel structure, under simulation of vibration deformation control model. Taking a chemical plant as an example, a finite element model was established to simulate the vibration wave, and the numerical simulation results of plastic deformation resistance of steel structure were analyzed. The experimental results show that the proposed method can effectively enhance the stability of steel structure and reduce its deformation degree.
Asphalt Concrete Characterization Using Digital Image Correlation: A Systematic Review of Best Practices, Applications, and Future Vision
Authors: Wang Siqi , Zhu Zehui , Ma Tao , Fan Jianwei
Published: February 2024

Digital image correlation (DIC) is an optical technique that measures displacement and strain by tracking pattern movement in a sequence of captured images during testing. DIC has gained recognition in asphalt pavement engineering since the early 2000s. However, users often perceive the DIC technique as an out-of-box tool and lack a thorough understanding of its operational and measurement principles. This article presents a state-of-art review of DIC as a crucial tool for laboratory testing of asphalt concrete (AC), primarily focusing on the widely utilized two-dimensional DIC and three-dimensional DIC techniques. To address frequently asked questions from users, the review thoroughly examines the optimal methods for preparing speckle patterns, configuring single-camera or dual-camera imaging systems, conducting DIC analyses, and exploring various applications. Furthermore, emerging DIC methodologies such as digital volume correlation and deep-learning–based DIC are introduced, highlighting their potential for future applications in pavement engineering. The article also provides a comprehensive and reliable flowchart for implementing DIC in AC characterization. Finally, critical directions for future research are presented.
Use of perioperative telotristat in a patient with carcinoid heart disease

Published: February 2024

Carcinoid heart disease is a rare complication of carcinoid syndrome, resulting in right-sided valvular heart disease and subsequent heart failure due to long-term exposure to vasoactive substances. The management of this condition is complex, often requiring surgical intervention. Current perioperative regimens entail the use of prophylactic somatostatin analogs to prevent carcinoid crisis; however, regimens vary widely among practitioners and evidence supporting their efficacy in this clinical setting is mixed. This case report describes the perioperative management of a 65-year-old man with carcinoid heart disease requiring tricuspid and pulmonary valve replacement surgery. As an adjunct to somatostatin analog therapy, the novel tyrosine hydroxylase inhibitor, telotristat, was initiated preoperatively. This combination resulted in normalization of preoperative urinary 5-HIAA levels. The patient successfully underwent tricuspid and pulmonic valve replacement without evidence of carcinoid crisis. This clinical case is the first published documenting the use of telotristat in the perioperative period in a patient with carcinoid syndrome and carcinoid heart disease and was associated with a good long-term outcome despite the high-risk nature of the case.

Learning points

Carcinoid crisis is a life-threatening complication of carcinoid syndrome, resulting in hemodynamic instability, bronchospasm, and arrhythmia.

Cardiac surgical patients with carcinoid syndrome present a unique challenge as they are subject to physiologic conditions and medications which can potentiate intraoperative carcinoid crisis.

Perioperative management of patients with carcinoid syndrome currently entails the use of prophylactic somatostatin analogs; however, these agents do not prevent carcinoid crisis in all cases.

Telotristat, a tryptophan hydroxylase inhibitor, shows promise as an adjunctive therapy to somatostatin analogs to reduce the risk of intraoperative carcinoid crisis.

Published: February 2024

Purpose: To explore and discuss theoretical and practical scientific literature to compare sports diversification and early sports specialization as a sport and educational approach.
Methods: A systematic review was conducted following PRISMA guidelines, and 61 studies were included.Results: Coaches, parents, and children consider that the best way to develop sports talent and enter the elite in sports is to practice a single discipline as early as possible to achieve specialization and maximum technical skills and physical and psychological conditions. Sports specialization paths may lead to a physical, social, and mental state that compromises their integral development.Conclusion: Sports diversification should be considered first at an early age and, afterward, the specialization once the bases of strength, conditioning, neuromuscular training, and a specific psychomotor maturation have been achieved, so that sports performance and health are not compromised in the medium or long term. It is necessary to consider that few children enter elite sports, so for many of them, sports education will be the basis for exercising their citizenship as active people.

The choice of winder type for various web materials has long been a qualitative discussion. Web materials are vast and hence the range of web material properties is also vast. Valid but conflicting opinions for an optimal winder type have been developed from experience bases that represent this vast range of web materials. The purpose of this publication is to quantify how the internal stresses in wound rolls are affected by winder type and web material properties.

The aim of this research is to gain more understanding of the physics of the transportation of materials having viscoelastic characteristics, high transport speeds, a small thickness and a large surface area. This study introduces new models that take into account both material viscoelasticity and the fluid-structure interaction between the travel- ling material and the surrounding owing fluid. A web (continuum) travelling between two fixed supports is considered, modelling the web as a Kelvin–Voigt type viscoelastic panel and the air ow as a potential ow. Stability of the system is studied with the help of its eigenfrequencies (eigenvalues) for two different types of ow geometries. First, a ow inside an enclosure with a rectangular cross-direction, through which the panel is travelling, is added to the equations of out-of-plane motion of the panel with the help of added mass coefficients. Secondly, a free stream potential ow obstructed by the travelling panel is analyzed using the analytical solution for the aerodynamic reaction pressure. Some numerical examples are given for both models.

It is widely accepted and discussed in the literature that fiber morphological parameters like fiber length, fiber curl and fiber flexibility affect flocculation phenomena and the properties of the fiber network in suspension via mechanical entanglement and forces arising at fiber to fiber contact points. The focus of this work is the interrelation of the parameters floc size distribution, network strength and fiber morphology. Pulp samples of different length distribution, fiber curl, kink index and fiber flexibility are evaluated concerning their flocculation tendency and the strength of the fiber network using methods already established in the literature. The simultaneous measurement allows the investigation of the interrelation of these parameters. It is shown that floc size distribution and network strength are highly correlated. Still, depending on the morphological properties fiber curl, kink index and fiber flexibility, samples of comparable floc size distribution and different network strength (and vice versa) are evident.

Nippon Paper industries has been developing Cellulose Nanofibre (CNF) products prepared by the fibrillation of chemically modified pulp since 2007. In November 2013 we started to operate a pre-commercial plant in order to provide CNF for the collaborators, potential users and internal use, after 5 years of fundamental research together with out collaborators with the aim of commercialization of products using CNF. In our pre-commercial plant, mainly TEMPO oxidized CNF is produced, a process developed by the research group of Prof. A. Isogai at The University of Tokyo. In addition t TEMPO oxidation, other chemical modifications such as carboxymethylation are carried out in out plant as well. Thus collaborators can choose the type of CNF samples, depending on their target applications. In 2016, NPI announced the plan to install a CNF full-scale production facilities at the Ishinomaki Mill and the Gotsu Mill in Japan. At the Ishinomaki Mill, CNF prepared by TEMPO oxidation will be produced, and at the Gotsu Mill, CNF prepared by carboxymethylation will be produced. In this brief paper we will present our developments of manufacturing techniques and applications of chemically modified CNF.

We report the cationic polyelectrolyte (CPAM)-SiO2 nanoparticle (NP) interactions in suspension and in a sheet form, when mixed with microfibrillated (MFC), using dynamic light scattering (DLS) and small angle X-ray scattering (SAXS) techniques. The CPAM-SiO2 NP suspensions were prepared by adding NPs into CPAM drop wise and composites were prepared by adding CPAM-SiO2 suspension into MFC and through standard paper making procedure. DLS revealed that increase in CPAM dosage creates larger sized CPAM-NP aggregates because more NPs can be picked up by stretched CPAM chains. SAXS study revealed that CPAM-SiO2 NP assembly in the formed nanopaper fits well with a spherical core shell model (with SiO2 partially covered with CPAM) and sphere model (SiO2 alone) combined together. Understanding the interaction between polyelectrolyte-NP system through such scattering techniques enables us to engineer novel cellulose based composites for specific applications.

In this paper we give a literature overview on three different aspects of pulp fiber-fiber bonding. First we are reviewing how the adhesion between the pulp fibers is created by the capillary pressure during drying of a sheet. Second we are discussing the individual mechanisms relevant for fiber-fiber bonding. They can be grouped in three different groups: (a) The area in molecular contact, which also includes interdiffusion; (b) the intermolecular bonding mechanisms hydrogen bonding, Van der Waals forces and Coulomb interaction; (c) the mechanical bonding mechanisms which are capillary bridges and mechanical interlocking. The third and last part of the review discusses the failure process of fiber-fiber bonds and related single fiber-fiber bond testing methods. The general emphasis of the paper is set on providing a general understanding of the processes responsible for how bonds between fibers are created, how they work and how they are failing.

A novel methodology is developed to visualize and quantify biomolecules adsorption at the cellulose film0liquid interface. Hydrogenated cellulose (HC) films were made from cellulose acetate and deuterated cellulose (DC) films produced using deuterated bacterial cellulose. Deuterated bacterial cellulose was obtained by growing the Gluconacetobacter xylinus strain ATCC 53524 in D2O media. Horse Radish Peroxidase (HRP), a robust and well knw enzyme, was selected as model functional biomacromolecule to adsorb at the cellulose interface. The film thickness and quantification of adsorbed HRP molecules were characterized by X-ray and neutron reflectivity (NR) measurements. Reflectivity data analysis reveals the cellulose films to be smooth (low roughness) and uniform. The HC and DC films are 206 A and 92 A thick, respectively, and both films swell in the aqueous buffer solution. In NR measurements, it is difficult to trace the adsorbed HRP layer on HC film due to the small scattering length density (SLD) difference between HC and HRP providing no contrast. However, using deuterated cellulose (DC) film provides sufficient SLD difference (contrast) with respect to the SLD of HRP. The adsorbed HRP layer is 110A thick and occupies a volume fraction of 20%. Using deuterated cellulose films enabled the quantification of thin and partial layers of proteins at the liquid interface. Quantifying and controlling the morphology and functionality of biomolecules at the cellulose interface enables to efficiently develop and optimize low cost cellulose based diagnostics devices with superior functionalization.

Background: Ongoing investigations established the relationship between adverse childhood experiences (ACEs) and chronic diseases, such as high blood pressure, diabetes, atopic dermatitis, and psoriasis. However, the specific association between ACEs and skin cancer remains relatively unexplored in scientific literature. Objective: This study aimed to evaluate the relationship between adverse childhood experiences (ACEs) and measures of health-related quality of life (HRQOL) among individuals with a skin cancer diagnosis. Methods: Data from the 2019 Behavioral Risk Factors and Surveillance Study (BRFSS) were analyzed. The study included 418,268 adults, with 41,773 individuals diagnosed with skin cancer. HRQOL measures, including physical health, mental health, and lifestyle impairment, were assessed using self-reported data. ACEs were identified through participants' responses to 11 specific questions. Multivariable logistic regression analyses adjusted for demographic variables. Results: Skin cancer survivors with a history of ACEs reported significantly poorer physical health (OR 1.39, 95% CI 1.24-1.56) and mental health (OR 2.13, 95% CI 1.81-2.51) compared to those without ACEs. They also experienced higher levels of lifestyle impairment related to health (OR 1.31, 95% CI 1.16-1.48). Commonly reported ACEs included parental separation, exposure to domestic violence, and verbal abuse. Discussion: This study highlights the detrimental impact of childhood maltreatment on HRQOL among skin cancer survivors. Healthcare professionals should be attentive to the unique needs of this population by providing comprehensive support and interventions. Conclusion: Childhood maltreatment has a significant negative impact on HRQOL among skin cancer survivors. The study emphasizes the importance of addressing the psychological and emotional well-being of individuals with a history of ACEs. Healthcare professionals should consider the specific needs of this vulnerable population to provide appropriate care and support. Further research is required to deepen our understanding of the underlying mechanisms and to develop effective interventions to improve the well-being of skin cancer survivors with a history of childhood maltreatment. Furthermore, longitudinal analyses and objective measures are needed to establish causal relationships and mitigate potential biases.

Purpose: This study aims to present a clinical case of significant reduction in submental fat using the Endolifting®technique and the 1470nm diode laser, supported by an extensive literature review. Case report: The ongoing quest for innovative and minimally invasive aesthetic procedures has propelled research in the field of aesthetic dermatology. Submental fat reduction, commonly referred to as a double chin, is a prevalent aesthetic concern that impacts facial harmony and the self-esteem of many patients. In this clinical case report, we introduce the application of the 1470nm diode laser in combination with the Endolifting®technique as a non-surgical alternative for double chin reduction. A 45-year-old patient with a prominent double chin performed a single treatment session. Following the treatment, a noticeable reduction in submental fat was observed, resulting in a more balanced and rejuvenated facial profile. The patient reported an enhancement in self-esteem and satisfaction with the outcomes. Conclusion: This case report validates the effectiveness of the 1470nm diode laser and the Endolifting®technique in reducing double chin, showing it as an innovative, efficient, safe, and replicable approach for submental fat reduction.

Published: February 2024

Acute abdominal pain is challenging because of the nonspecific nature of symptoms and difficulties in physical examination in children. In most of them, it is a manifestation of an urgent surgical or medical condition, where the biggest challenge is a timely diagnosis to start appropriate treatment without any diagnostic delays. There are many conditions that present with abdominal pain in all age groups, ranging from a common viral illness to a life-threatening surgical condition. History, physical examination, laboratory tests, and imaging are initially used to differentiate surgical illnesses categorized as urgent. Their characteristics, age, and physical examination of the patient direct appropriate tests in the context of these differences.
MINIMALLY INVASIVE OSTEOSYNTHESIS WITH PLATE OR NAIL FOR META-DIAPHYSEAL TIBIAL FRACTURES - WHAT IS BETTER?
Authors: Makelov B.
Published: February 2024

The aim of this article is to review the surgical techniques for minimally invasive osteosynthesis and associated complications with application of locking compression plates, which have undeniable biomechanical and biological advantages in the treatment of multifragmentary meta-diaphyseal tibial fractures. Unstable proximal tibial fractures include a vast majority of fracture patterns affecting the lower extremities. Most of the fracture types are as a result of high-energy trauma from car accidents, high-altitude injury or motor vehicle incident. Usually, those fractures present with severe soft tissue injury with varying degrees of intra-articular fracture involvement. Intramedullary nailing of tibial fractures as a proven method of biologic fixation and represents one of the most widely used methods for the treatment of unstable fractures involving the proximal meta-diaphyseal area of the tibia, allowing sufficient fracture stability during the early limb movement and weight bearing on the leg. Nevertheless, the complications and technical difficulties in its application raise the question for the choice of an appropriate implant in the treatment of these fracture models in terms of their morphology. Minimally invasive percutaneous plate osteosynthesis with indirect reduction and biologic fixation has the advantage of spearing the local blood flow, even in severely comminuted tibial fracture patterns. The use of pre-contoured locking compression plates for proximal tibia allows stable fixation with good and excellent final clinical results.
LOW-GRADE FIBROMIXOID SARCOMА OF LOWER LЕG IN YOUNG FEMALE PATIENT- REPORT OF A RARE CASE

Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft tissue neoplasm described for the first time by Evans in 1987. It may affect the subcutaneous soft tissues or subfascial space. It usually arises from deeply located soft tissue structures of extremities, head and neck, thorax, and retroperitoneum.
We present a case of a female patient of age 24, admitted to the Department of “Surgical Diseases” of Medical University Hospital “ D-r G. Stranski” Ltd – Pleven in July 2022, with complaints of a slowly growing non-painful soft mass, located on her right lower leg, distal 1/3 part, anteriorly initially suspected for lipoma. After wide surgical excision grossing and histological and immunohistochemical verification of the specimen, the result was LGFMS G1 pT1. We perform a literature review for another case in the world with that rare tumor. The tumor is with distinct biological behavior. Despite its low grade and benign histological appearance, it has a high potential for metastasizing, years after the primary surgical excision of the tumor, and it has a high risk for local recurrence. Because of the high risk of late metastasis, the follow-up period should be long and monitoring of the lung and chest is mandatory.

This annotated bibliography comprises 49 texts concerning psilocybin mushroom practices developed by Indigenous peoples. The books and articles have been selected for their academic rigor, relevance, and historical significance, and to foreground overlooked research and subject matter. This includes research on a plurality of contemporary practices and evidence of historical uses, from cultural traditions in Mexico and other regions of the world. The curated texts are sourced from various disciplines, including anthropology, history, archaeology, ethnolinguistics, and ethnomycology. Employing diverse methodological and analytical frameworks, the texts explore the diversity of ways Indigenous cultures have related with, utilized, and conceptualized psilocybin mushrooms and the effects occasioned by their consumption. The annotations include brief summaries of the texts, contextualization of the research, and more critical appraisals. The aim of this annotated bibliography is to offer the reader a diverse overview of the research to date and provide an accessible resource for further exploration of historical and contemporary Indigenous psilocybin practices. The team of psychedelic researchers behind this annotated bibliography hope it will contribute to more nuanced dialogue around Indigenous people and practices in the context of the so-called psychedelic renaissance.
Perjuangan HTI dalam Sistem Kenegaraan di Indonesia dan Metamorfosisnya di Media Online
Authors: Wahid Annisa , Saputra Yayan , Ali Wan Zailan Kamaruddin Wan
Published: February 2024

HTI (Hizbut Tahrir Indonesia) adalah gerakan Islam transnasional yang mengadvokasi berdirinya kekhalifahan Islam secara global. Penelitian ini bertujuan untuk memahami bagaimana perjuangan HTI menegakkan sistem khilafah di Indonesia dan bagaimana kelompok BMI hasil metamorfosis HTI menyebarkan ideologinya dan menjalankan gerakan-gerakan HTI yang telah dilegalkan pemerintah. Penelitian ini menggunakan metode penelitian teks kualitatif, meneliti buletin, ceramah, dan blog yang dibagikan secara online oleh kelompok BMI. Data dan sumber data penelitian ini diperoleh melalui tinjauan pustaka berupa buku, jurnal, dan literatur yang membahas objek penelitian. Untuk teknik analisis data, peneliti menggunakan teori gerakan sosial yaitu teori framing dan teori media siber. Hasil penelitian ini menunjukkan bahwa kelompok HTI setelah dibubarkan oleh pemerintah tidak berhenti melainkan bertransformasi menjadi kelompok lain seperti bergabung dengan kelompok BMI (Back To Muslim Identity). Hal ini terlihat dari kesamaan ideologi dan pola gerakan HTI dan BMI. Kedua ideologi tersebut bertujuan untuk mendirikan khilafah di Indonesia. Dalam pemahaman BMI, mereka menolak ideologi di luar Islam, seperti demokrasi, kapitalisme, komunisme, dan liberalisme. Dalam menjalankan gerakannya, baik HTI maupun BMI mempunyai pola serupa, seperti menyebarkan keyakinannya melalui media online, turun ke jalan, menyebarkan buletin, mengorganisir demonstrasi, dan melakukan pendekatan kepada tokoh masyarakat.
