Published: July 2023

Utilization of various learning models at SMP Negeri 20 Bandar Lampung is not optimal. Yet, teachers only use conventional learning models to teach various learning materials and are more active during learning than students. This causes low students' mathematical problem-solving abilities in learning mathematics, so students get a low value. The study aimed to determine whether the mathematical problem-solving abilities of students who used the discovery learning model were better than those whose learning used conventional models in class VII students of SMP Negeri 20 Bandar Lampung. This research is a quasi-experimental design study with two groups. The data collection technique used is a test of mathematical problem-solving ability. The analysis technique in this study is a statistical technique through the t-test. The results of this study indicate that students using the discovery learning model are better than students whose learning uses conventional models on students' mathematical problem-solving abilities.

Dispositivo ecfrastico e la sua temporalità
Authors: Verdone Alessio
Published: July 2023

In questo lavoro si ripercorrono alcune possibili interpretazioni dell’ekphrasis, da quelle classiche a quelle più innovative. In primo luogo, si cerca di superare definizioni che limitano la portata delle tecniche ecfrastiche, per rivolgersi verso prospettive più ampie che inglobino funzioni finora trascurate. Per andare verso questa direzione si separano i due momenti dell’operazione ecfrastica – l’ekphrasis-come-processo e l’ekphrasis-come-testo – e si leggono in chiave dispositiva. Successivamente si approfondisce la temporalità del dispositivo testuale ecfrastico, rileggendolo come forma di integrazione della simultaneità spaziale tipica dell’immagine e della processualità consequenziale tipica del segno verbale. Infine, si osservano da vicino due realizzazioni ecfrastiche di Sanguineti – Reisebilder 14 e Cose 2 – che presentano un’articolazione temporale degna di nota, in cui visualità e verbalità si confrontano in maniera tale che se da un lato vengono sollecitati gli elementi processuali latenti nella prevalente simultaneità dell’immagine, dall’altro alcune porzioni di simultaneità caratterizzante dell’immagine vengono integrate nella prevalente processualità del testo ecfrastico.
Wilhelm Dilthey e il secondo mondo della letteratura
Authors: Pasini Giovanni Quinto
Published: July 2023

L’articolo presenta un inquadramento teorico riguardante la riflessione di Wilhelm Dilthey sulla letteratura. Si considereranno, in particolare, la proposta metodologica della Poetik del 1887 e la concezione dell’opera letteraria che compare negli scritti della maturità successivi al 1905, quando la teoria della conoscenza diltheyana è aggiornata sulla base del rapporto fra Erleben, espressione e comprensione. Si noterà in tal modo come Dilthey dalla sua fase di riflessione mediana a quella matura passa da un proposito di studio normativo della facoltà immaginativa a un discorso descrittivo sulle potenzialità conoscitive che l’opera letteraria riserba per relazionarsi a un’esperienza soggettiva ulteriore rispetto a quella personale, sulla scorta della rilevanza attribuita nei suoi ultimi scritti al concetto di comprensione riproducente.

Gesto, parola, narrazione
Authors: Invernizzi Simone
Published: July 2023

Il contributo illustra le ricerche sull’evoluzione umana condotte dallo psicologo Michael Tomasello e la sua ipotesi dell’intenzionalità condivisa, per mostrare come tale prospettiva possa rivelarsi feconda anche per gli studi di teoria letteraria. Il pensiero di Tomasello è analizzato e messo in dialogo con altri studiosi (Donald, Corballis, Di Martino, Piaget, Nelson, Hutto, Ricoeur, Porter Abbott, Sloterdijk) per tracciare una storia evolutiva del linguaggio – gesto, parola, narrazione –, considerato come uno strumento di imitazione del mondo. La nascita del linguaggio innesca conseguenze a cascata, che hanno ricadute profonde sullo sviluppo del soggetto umano. Nella parte finale viene evidenziato il ruolo decisivo della mimesi narrativa nel processo di strutturazione del pensiero (memoria e immaginazione) e della socialità umani, accennando alle differenze tra l’uso quotidiano dei racconti e il fenomeno letterario vero e proprio.

Application of Temporary Anchorage Devices in Orthodontics: A Literature Review
Authors: Otaren Joseph , Iyamu Idia
Published: July 2023

Anchorage control is one of the most essential keys for success in clinical orthodontics. Anchorage loss is a primary concern associated with orthodontic procedures. Numerous devices have been proposed and used for over a century to get the appropriate anchorage. Extraoral anchorages such as headgears or facemasks are the most effective tools but are limited because their effectiveness depends on patient compliance. Using skeletal anchorage, such as Temporary Anchorage Devices (TADs), to retract anterior maxillary teeth is an old technique developed in 1945. Despite their small diameter and short length, TADs can provide stable anchorage for multiple tooth movements, including intrusion, retraction, and protraction. This article examined the various applications of temporary anchorage devices (TADs) in clinical orthodontics. The risk factors and complications of TADs application in clinical orthodontics were identified. As the younger generations of orthodontists enter practice and the academic arenas, TADs use will continue to increase if trends continue as they have in the past several years.
Association of gut microbiota in the pathogenesis of acute respiratory distress syndrome and possible pharmacotherapy by sphingosine-1-phosphate
Authors: Amin Tasbir , Zahed Fahd
Published: July 2023

The Acute Respiratory Distress Syndrome (ARDS) is one of the major heterogeneous clinical manifestations of severe respiratory failure developing in response to pathogenetic mechanisms and several inflammatory insults. The translocation of gut microbiota has a crucial impact on the pathogenesis of ARDS. Hence, a deeper understanding of the interplay of the gut microbiota would allow shedding valuable insights into both the pathogenesis of ARDS and the development of effective therapeutic interventions. Moreover, the modulation of gut-lung axis could also play a pivotal role in minimizing the lung dysbiosis with gut microbiota. There is little question that greater study of the gut-lung axis in critically ill patients is required to establish causal links between the shifted microbiota, infections, inflammation, and acute lung damage. It is worth mentioning that the lack of effective preventative measures is one of the main reasons for the increased mortality rate of 30-40% in ARDS patients. Some antibiotics and nanosized drugs showed positive results in ARDS management to some extent in pre-clinical or even first stages of clinical trials but large-scale results had been controversial. However, Sphingosine-1-Phosphate (S1P) showed hopeful results in ARDS patients by facilitating both systemic and endothelial integrity. Numerous investigations have shown the immunological connection between the gastrointestinal tract and the respiratory system. As the SphKs /S1P /S1PL metabolic pathway is associated with a wide variety of human illnesses (including respiratory diseases), it should come as no surprise that influencing intracellular S1P levels would have therapeutic promise in reducing the severity of lung diseases like ARDS.
Molecular characterization of multidrug-resistant bacteria isolated from the external and internal parts of the housefly
Authors: Zuhora Fatema , Hosen Md , Rumi Nazmi , Rahman Md , Alam Jahangir , Hasan Md
Published: July 2023

House flies are mechanical vectors of food borne enteric pathogenic bacteria which may transfer isolates to human and produce diseases. In Bangladesh, there is very limited data on molecular characterization of drug-resistant bacteria from isolated house flies. The research was conducted to determine the pathogenic bacteria isolated from houseflies in different location in Dinajpur district of Bangladesh and their antibiogram study for a period of one year from June, 2019 to July, 2020. A total of 140 houseflies were randomly collected and submitted to bacteriology lab, Hajee Mohammad Danesh Science and Technology University for microbiological analysis. A group of cultural tests, biochemical tests were used to isolation and identification of isolates and further confirmed through molecular characterization by the presence of 16S rRNA gene E1, E2 and invA. Additionally, 14 commercially available antibiotics were used by karby-bauer disk diffusion technique for antibiogram study. Results showed that the most commonly isolated bacteria from houseflies' external surfaces were Escherichia coli 19.04%, Salmonella typhimurium 15.87%, and Pseudomonas spp. 7.93% from 63 isolates, while 42 isolates found 35.71%, 28.57%, and 14.28% respectively. PCR amplification bands of Escherichia coli, Salmonella typhimurium, and Pseudomonas spp. were 584bp, 284bp, and 1497bp. Almost all the isolates were highly resistant to erythromycin, gentamycin, bacitracin (100%), followed by kanamycin, methicillin (80%) whereas highly sensitive to ciprofloxacin, chloramphenicol, azithromycin (100%), followed by tetracycline, amoxicillin (85.71%). These pathogenic microorganisms at distinct sampling sites indicate house flies may transmit vector-borne pathogens to humans. Based on these findings, we recommend vector-borne disease-fighting medications and a sustainable house fly-control approach. We also suggest promoting hygiene and food safety protocol to distance food ingredient from flies in local markets.

Development of Smart Potentiometric Sensors Covered with Non-Biofouling Layer for Detection of Early Stages of Inflammatory Processes Around Joint Replacements
Authors: Ivanko Iryna , Tomšík Elena , Hrubý Martin
Published: July 2023

One of the problems occurring after the joint replacement is connected with the post-surgery infections which are caused by bacteria that form biofilms on surfaces and are referred to as biofilm-related infections (BRI). It is also worth noting that due to the bioresponse, strong pathophysiological changes in the microclimate of an affected surface occur (decrease in pH, formation of various reactive oxygen species (ROS), depletion of Fe ions, and increase in the concentration of Ca ions). In this work we have prepared a robust selective potentiometric sensor of ROS and pH sensor for the detection of pH changes caused by sterile inflammation and bacterial and fungal infections. The ROS sensor consists of a conductive polymer layer based on polythiophene with an incorporated porphyrin-metal complex that potentiometrically detects the presence of ROS (H2O2 and ClO– ions). This sensor is connected by the covalent bonds with a non-biofouling layer of poly(2-methyl-2-oxazoline), which works as a bio-compa­tibilizer. It was shown that the potentiometric sensor shows a rapid response to hydrogen peroxide, does not record any interference with bovine serum albumin as a model serum protein, and is able to fully reversibly detect ROS with a linear response within a wide range of biological relevant concentrations (from 0.05 μM to 10 μM). The sensing electrode based on polyaniline and poly(2-methyl-2-oxazoline) on a titanium alloy support was developed for the potentiometric detection of peri-implant pH changes to enable early detection of the aforementioned pathologies. The developed electrodes show the changing of pH in the range between 5 and 8 for the individual pathogenic bacteria or pathogenic yeast, with a Nernstian slope of −59.6/pH.

Relações de cuidado em situação de vulnerabilidade social: uma experiência cínico-institucional
Authors: Neves Beatriz Sernache de Castro , Dauer Érika Teles , Martins Karla Patrícia Holanda
Published: July 2023

O trabalho é resultado da articulação de duas teses de doutorado que tiveram o Instituto da Primeira Infância (IPREDE) como campo de pesquisa. Historicamente, comprometida com o enfrentamento a desnutrição infantil, a instituição com o tempo passa a contemplar a noção de desenvolvimento infantil de uma forma mais geral incluindo a família nas suas intervenções bem como estratégias de quebra de ciclos intergeracionais de pobreza. Dessa forma, a instituição passa a trabalhar com a noção de que os cuidados parentais são fundamentais no desenvolvimento infantil e na constituição subjetiva desses sujeitos. No entanto, essa tarefa é complexificada nas situações em que as famílias estão constantemente envolvidas em questões cruciais para a garantia da própria sobrevivência, sendo necessário pensar nas trocas intersubjetivas incluindo questões como gênero, racialidade e vulnerabilidade psicossocial. Através de uma vinheta clínica pretendemos mostrar como com frequência, o conhecimento técnico e especializado delimita as razões explicativas dos fenômenos que envolvem a infância sob uma lógica de responsabilização individual que recai na figura materna. Quando se responsabiliza a mãe pela condição do filho, promove-se, por vezes, uma experiência de desautorização, podendo provocar a negação de suas vivências e na perda do sentimento de si. Nesse cenário, circunscreve-se a urgência de pensar práticas de cuidado que se distanciem da avaliação da capacidade materna de cuidar e a ampliem a idéia de um olhar de acolhimento, apontando para uma responsabilização coletiva que permitam a vivência de uma experiência compartilhada.

Neoproterozoic Snowball Earth extent inferred from paleosols in California
Authors: Retallack Gregory
Published: July 2023

Gelisol paleosols with sand wedges and sorted stone stripes are reported from the early Cryogenian (717–659 Ma), Surprise Diamictite Member and Sourdough Limestone Member of the Kingston Peak Formation in Redlands Canyon, western Panamint Range, California. The Surprise Diamictite was thus not entirely marine, although glaciomarine sediments and tectonically induced, mass wasting deposits, may be present in other parts of the Kingston Peak Formation. Sand wedge and stone stripe paleosols are evidence of local ice–free land with frigid continental climate at paleolatitude as low as 8 ± 4º from paleomagnetic studies of the Surprise Diamictite. The Sturt glaciation was a dramatic global cooling, but not a global snowball. Bare ground of landslides, alluvial fans, till and loess with mineral nutrients, and microtopographic shelter for complex life on land would have been important for survival of life on Earth from glacial destruction.

“Speaking of sexuality”: Enhancing comfort and confidence among nurses caring for older patients
Authors: Levkovich Inbar
Published: July 2023

Human sexuality, a fundamental aspect of overall health and well-being, persists throughout all stages of the human lifecycle, including advanced age. Research demonstrates that a significant number of older adults maintain interest in sexual activity and continue to be sexually active during their later years. Nurses and healthcare providers must learn to understand the intricate interplay of psychological and physical influences leading to sexual difficulties among older individuals. Such knowledge is critical when providing effective assistance to older adults grappling with sexuality-related concerns. Given that the over 65 population accesses healthcare services frequently, healthcare professionals serve as pivotal intermediaries in addressing sexual issues. Nevertheless, medical personnel often feel uncomfortable and unsure about initiating conversations about sexuality among this population. This paper explores the reasons underlying the common tendency among healthcare professionals to avoid such discussions and suggests strategies to ameliorate this situation.

Red blood cell distribution width (RDW) is an inflammatory biomarker reported in complete blood cell (CBC) counts. High RDW deﬁnes a proinﬂammatory state. Contrast-induced nephropathy (CIN) is an important and common complication in percutaneous coronary intervention (PCI) treated patients. The current study was conducted to evaluate the role of RDW as a simple predictive inflammatory marker of CIN in PCI treated patients. The current prospective study enrolled 126 PCI treated patients. Laboratory investigations included CBC, liver function test, (HbA1C), lipid profile and serological tests. Serum urea and creatinine levels were obtained at baseline and 48 to 72 hours after PCI procedure, used to categorize for CIN. Diabetes mellitus, hypertension, and ischemic heart disease were present in 39 (31%), 44 (34.9%), and 23 (18.3%) patients, respectively. Of the studied patients, only 19 (15.1%) patients developed CIN. The hemoglobin level was significantly higher in the non-CIN group (13.49 ± 1.63 vs. CIN group 12.56 ± 1.62 mg/dl; p= 0.02). RDW was significantly higher among CIN group than non-CIN group (16.20 ± 2.60 vs. 13.83 ± 2.19 % (p< 0.001). Delta creatinine (% change in creatinine level after 48 hour) was significantly higher in patients with CIN (59.17 ± 28.89 vs. non-CIN 33.62 ± 9.76; p< 0.001). Predictors for CIN in patients who underwent PCI were old age high RDW high delta creatinine and amount of dye. At cut off > 14.5%, RDW had 79% sensitivity, 70% specificity and 71.3% overall accuracy at AUC of 0.76. In conclusion, RDW may be simple and immediately available inflammatory biomarker and predictor for development of CIN in patients undergoing PCI.

Diabetes mellitus (DM) is a metabolic disorder of the proteins, lipids, and carbohydrates, results in hyperglycemia. Abnormalities in the function of insulin on target cells, its release from beta cells, or both may contribute to DM. The purpose of this research was to assess the progression of diabetic retinopathy (DR) to the levels of serum brain-derived neurotrophic factor (BDNF), glycated hemoglobin (HbA1c), and biochemical parameters. The study included 44 normal control subjects, 44 diabetic participants, who were separated into four groups based on their diabetes status and the results of fundoscopic examination. A commercial enzyme-linked immunosorbent assay kit was used to measure the levels of BDNF in the serum. The analysis revealed that diabetics had significantly lower serum BDNF levels than non-diabetics (p< 0.001). Also, there was a significant reduction in BDNF levels with the development of proliferative diabetic retinopathy in comparison with diabetics without DR (p < 0.001). In conclusion, serum BDNF levels decreased significantly in diabetics with and without DR compared to apparently healthy individuals, as well as with the progression of DR.

Ankylosing spondylitis (AS) is a chronic disabling rheumatic disease with indefinite etiology. Human leukocyte antigen-B27 (HLA-B27) carriage and Klebsiella pneumoniae (K. pneumoniae) infections may contribute to the etiopathogenesis of AS. The objective of this study was to determine the association of HLA-B27 carriage, serum immunoglobulin G (IgG) to K. pneumoniae with AS, and its clinical outcome. In a case-control study, HLA-B27 carriage was detected by polymerase chain reaction, serum IgG to K. pneumoniae was measured by ELISA, and K. pneumoniae was isolated from the stool of 40 AS patients who were compared to age and sex-matched 40 normal individuals. Clinical findings, disease activity, and functional ability were evaluated for all AS patients. HLA-B27, serum IgG to K. pneumoniae, and fecal carriage of Klebsiella were significantly higher in AS patients when compared to controls (p <0.001 for all). Disease activity and functional score categories were significantly higher in HLA-B27 positive AS patients with an elevated titer of K. pneumoniae IgG than in HLA-B27 negative patients with low titer of K. pneumoniae IgG (p <0.012 and p<0.001, respectively). In conclusion, HLA-B27 carriage and K. pneumoniae infections could play a significant role in the development and clinical outcome of AS patients.

Patients with rheumatoid arthritis (RA) have a higher risk of cardiovascular disease (CVD) compared to the general population, which leads to increased morbidity and mortality. Inflammation is the key in RA and CVD. Our study aimed to refine cardiovascular (CV) risk assessment in RA patients by using carotid intima-media thickness (cIMT) as a marker of subclinical atherosclerosis. We also explored whether proinflammatory cytokines represented by tumor necrosis factor-alpha (TNF-α) and high-sensitivity cardiac troponin I (hs-cTnI), a biomarker of myocardial injury, could be correlated in RA patients. The study included 80 RA patients and 80 control subjects. TNF-α and hs-cTnI levels were measured. Subclinical atherosclerosis was evaluated by cIMT by means of carotid ultrasound. Disease activity score 28 (DAS28) was used to evaluate disease activity. hs-cTnI and TNF-α serum levels were higher in RA patients compared to controls (p=0.001). There was a significant difference in the median of cIMT between cases and controls (median (IQR) 0.9 (0.2) for cases, 0.7 (0.1) for controls, (p=0.001). A significant correlation was found between the level of TNF-α and hs-cTnI (p=0.002). Also, there was a significant correlation between the cIMT level and TNF-α and hs-cTnI (p=0.003 and p=0.002, respectively). Significant correlation was found between cIMT, TNF-α, and hs-cTnI in relation to the DAS28 score (p<0.001, p<0.001, and p=0.001, respectively). In conclusion, patients with RA are more likely to develop subclinical atherosclerosis, as reflected in increased cIMT. Higher levels of hs-cTnI in RA patients may correlate with the presence of occult cardiovascular disease. TNF-α and hs-cTnI correlations can reveal the interplay between disease activity and CVD. Thus, inflammation must be the primary target of various therapeutic approaches.

Sarcoidosis is a multisystem granulomatous disease of unknown origin. Ninety percent of patients with sarcoidosis have lung involvement. The onset can be acute or non-acute and the severity of sarcoidosis ranges widely from asymptomatic patients with accidental radiographic findings to patients with severe organ involvement. This case control analytic prospective study was conducted at the Chest Clinic, Al Zahraa hospital, to assess the diagnostic value of serum soluble interleukin 2 receptor (sIL-2R), cluster of differentiation 4 (CD4)/CD8 ratio and CD103 in sarcoidosis. We investigated the value of serum sIL-2R using ELISA and blood CD103, blood CD4/CD8 ratio using flow cytometry for 30 cases of sarcoidosis in different stages and 30 control persons to detect their use as a marker for diagnosis. We found a significant increase in sIL-2R in the sarcoidosis group as compared to the control group (p˂0.0001), while there was a significant decrease in CD103/CD4 in sarcoidosis group as compared to the control group (p <0.001). In conclusion, sIL-2R and CD103 can be used as diagnostic markers for sarcoidosis.

The nucleotide-binding oligomerization domain-like receptor 3 (NLRP3) inflammasome is a high molecular weight protein complex that has been linked to a variety of allergic and inflammatory disorders in humans, including atopic dermatitis (AD). Polymorphisms in NLRP3 genes could lead to immune dysregulation. This case-control study aimed to assess the association between NLRP3 inflammasome (rs10754558) gene polymorphism in AD and the incidence and severity of the disease. We included 62 subjects in each of the AD and control groups. Serum total IgE levels and NLRP3 inflammasome (rs10754558) gene polymorphism were assessed and compared between the two study groups and among the AD group as arranged by disease severity. The AD group showed significantly higher levels of serum total IgE compared to controls (p˂0.001). Serum IgE levels were also significantly associated with AD severity. The (rs10754558) G allele was significantly predominant among AD participants (OR: 2.33; 95% CI: 1.1 -4.92) and 51.6% of the AD group was carriers of the GG genotype. Moreover, there was a substantial correlation between NLRP3 (rs10754558) G allele and AD score index for disease severity (OR: 7.17; 95% CI: 1.47 – 35.7). In conclusion, NLRP3 inflammasome (rs10754558) gene polymorphism G allele could be an important factor in the predisposition and exacerbation of AD.
