Smooth permutations and polynomials revisited
Authors: GORODETSKY OFIR 
Published: December 2024

AbstractWe study the counts of smooth permutations and smooth polynomials over finite fields. For both counts we prove an estimate with an error term that matches the error term found in the integer setting by de Bruijn more than 70 years ago. The main term is the usual Dickman
$\rho$
function, but with its argument shifted.We determine the order of magnitude of
$\log(p_{n,m}/\rho(n/m))$
where
$p_{n,m}$
is the probability that a permutation on n elements, chosen uniformly at random, is m-smooth.We uncover a phase transition in the polynomial setting: the probability that a polynomial of degree n in
$\mathbb{F}_q$
is m-smooth changes its behaviour at
$m\approx (3/2)\log_q n$

Published: December 2024

AbstractIn topological band theory, phonon boundary modes consequence of a topologically non-trivial band structure feature desirable properties for atomically-precise technologies, such as robustness against defects, waveguiding, and one-way transport. These topological phonon boundary modes remain to be studied both theoretically and experimentally in synthetic materials, such as polymers and supramolecular assemblies at the atomistic level under thermal fluctuations. Here we show by means of molecular simulations, that surface-confined Su-Schrieffer-Heeger (SSH) phonon analogue models express robust topological phonon boundary modes at heavy boundaries and under thermal fluctuations. The resulting bulk-heavy boundary correspondence enables patterning of boundary modes in polymer chains and weakly-interacting supramolecular lattices. Moreover, we show that upon excitation of a single molecule, propagation along heavy-boundary modes differs from free boundary modes. Our work is an entry to topological vibrations in supramolecular systems, and may find applications in the patterning of phonon circuits and realization of Hall effect phonon analogues at the molecular scale.

Published: December 2024

Sur la base des contributions au dossier thématique des Cahiers Agricultures intitulé « Le foncier irrigué : enjeux et perspectives pour un développement durable », cet article introductif propose d’aborder l’objet « foncier irrigué » et les enjeux qu’il soulève par le prisme d’une approche socio-matérielle. Cette approche se nourrit de la notion d’assemblage et conçoit le foncier irrigué comme une entité sui generis résultant de relations et pratiques de bricolage « au quotidien » de la part d’acteurs insérés dans des réseaux multi échelles. Le foncier irrigué est envisagé comme une entité à la fois empirique et discursive, émergente et évolutive dans le temps et dans l’espace, qui évolue au gré de multiples recombinaisons entre eau(x), terre(s), cultures, et infrastructures mais aussi d’imaginaires, de discours et d’une économie politique globalisée de l’irrigation. D’un point de vue analytique, l’approche socio-matérielle est une approche relationnelle ancrée dans l’idée qu’il n’y a rien de « naturel » dans ce qui est communément appelé « ressources (naturelles) » : terres et eaux « deviennent » ressources via un jeu complexe de mises en relations et de pratiques. Dans une telle perspective, c’est bien le foncier irrigué, en tant qu’assemblage socio-matériel particulier et évolutif, qui fait ressource sui generis et non au travers des eaux, terres, cultures, et infrastructures qui le composent. C’est sans doute en cela que notre proposition diffère de la littérature existante sur le foncier irrigué qui tend à prendre ces catégories comme points de départs de l’analyse.
Advancing Prognostic Prediction in Pediatric Trauma: The Role of
Inflammatory Markers
Authors: Özel Abdulrahman , Yuce Servet , Ilbegi Esra Nur 
Published: December 2024

Abstract
Background This study aimed to evaluate the prognostic value of various
inflammatory markers and indices derived from complete blood counts in
predicting mortality among pediatric trauma patients admitted to the Pediatric
Intensive Care Unit (PICU).
Patients and Methods We designed a single-center retrospective study that
included 165 pediatric trauma patients in the PICU between January 2020 and June
2024.
Results Of 165 patients, 108 (69.2%) were male and the mean age of all
patients was 75.16±57.14 months. The mortality rate was found to be 5.45% (9
patients). The Lactate-to-Albumin Ratio (LAR) and Procalcitonin (PCT)
demonstrated strong prognostic performance with area under the curve (AUCs) of
0.807 and 0.745, respectively. Notably, LAR and PCT correlated well with
mortality and the duration of invasive mechanical ventilation and PICU stay. The
Systemic Immune-Inflammation Index (SIRI), Neutrophil-to-Lymphocyte Ratio (NLR),
CRP-to-Albumin Ratio (CAR), and Pan-Immune-Inflammation Value (PIV) were less
effective individually but showed potential when combined with other
indices.
Conclusion LAR, PCT, SIRI, NLR, CAR, and PIV were associated with
mortality in pediatric trauma patients, with LAR and PCT demonstrating superior
predictive value. Therefore, LAR and PCT may serve as reliable standalone
markers for identifying critically ill pediatric trauma patients at risk of
mortality.

Abstract
Objectives The aim of this research is to evaluate/compare the use of traditional versus sleeve fixed partial denture (PD) designs made from different materials on supporting structures. The comparison included three- and four-unit PD cases.
Materials and Methods Four finite element models are used in the research. The three-unit PD consists of the mandibular second premolar, first molar (as a pontic), and second molar. The four-unit PD includes the first premolar. The PD materials assessed were zirconia, E-max, and Celtra Duo. Bone has been simplified representing it as two cuboids. Each PD has been loaded to two cases over the pontic's central fossa: 300 N compressive, 150 N obliquely applied with 45 degrees forming 24 cases.
Results The three-unit traditional and sleeve PDs material change showed a slight change in cortical bone stress under vertical loading. Under oblique loading, cortical bone Von Mises stresses were higher by about 12 to 15% more than vertical loading. On the other hand, the four-unit PDs showed minor effect by changing PD material, while using sleeve design PD can reduce the cortical bone stresses up to 20% in comparison to traditional PD design. The mucosa and spongy bone were negligibly affected by changing PD material, and the traditional and sleeve designs showed close values to each other. Superiority of sleeve design appeared by reducing cement layer stresses dramatically, while PD body material rigidity affects its response.
Conclusion Within the limitations of this study, the higher rigid PD material can dissipate loadings over it more preferably regarding its effect on the underlying structures. Sleeve PD design is equivalent to the traditional one for three-unit PDs, while it showed better performance with four-unit PDs. Zirconia three-unit PDs' bodies received the lowest stresses and redistributed and transferred the applied load to the underneath structures better than the other two tested materials. This finding was reversed with four-unit PDs.

Published: December 2024

Abstract
Objective The purpose of the study was to evaluate the efficacy of calcium hydroxide (Ca(OH)2) and propolis in pulp capping for dental caries treatment, focusing on dentin growth parameters. The study also aims to determine the role of propolis as a natural adjuvant therapy in enhancing reparative dentin development while emphasizing the importance of proper technique and material preparation with markers for the expression of beta-catenin, bFGF, CD105, and BMP4.
Materials and Methods The left bottom molar teeth from 28 Wistar rats were divided into four groups. The first group, the control group, was given only aqua dest, and the second group received drilling treatment and additional therapies with Ca(OH)2 (Ca(OH)2) 0.625 μg. The third group was given drilling treatment and additional therapies with a combination of propolis with Ca(OH)2 0.781 μg until day 7. Finally, the fourth group received a combination of propolis with Ca(OH)2 0.781 μg until day 14. This research analyzed the expression of essential basic fibroblast growth factor (bFGF), CD105, beta-catenin, and bone morphogenetic protein 4 (BMP4).
Results This research reports that the average expression of BMP4 and bFGF showed a significant result in treatment with additional therapies with propolis and Ca(OH)2. The experiment indicates that propolis and Ca(OH)2 could induce reparative dentine on days 7 and 14.
Conclusion Propolis as an adjuvant shows better reparative dental formation with improvement in the expression of bFGF and BMP4 in 14 days of therapy.

Published: December 2024

Abstract
Objective This study compared the flexural strength, surface hardness, and surface roughness of conventional, milled, and three-dimensional (3D)-printed provisional restorations.
Materials and Methods Bar-shaped polymethyl methacrylate (PMMA) specimens (25 × 2 × 2 mm3) and disc-shaped specimens (9 × 2 mm2) were fabricated using three different techniques (n = 10/group): conventional (SR Ivocron C&B, Ivoclar Vivadent, Schaan, Liechtenstein), milling (Aidite Temp PMMA Blocks, Aidite, Qinhuangdao, China), and 3D printing (Asiga DentaTOOTH, Asiga, Sydney, Australia). Flexural strength was evaluated using a universal testing machine until fracture occurred. Vickers hardness and surface roughness tests were performed on the disc-shaped specimens using a micro-Vickers hardness tester and atomic force microscopy, respectively.
Statistical Analysis Data were statistically analyzed using one-way ANOVA. The post hoc Tukey's honest significant difference was conducted to compare the differences value between groups (p < 0.05).
Results The milled computer-aided design/computer-aided manufacturing (CAD/CAM) provisional restorative material exhibited a significantly higher flexural strength (125.16 ± 6.83 MPa) compared with both the traditional (109.74 ± 14.14 MPa) and 3D-printed (71.09 ± 9.09 MPa) materials (p < 0.05). The conventional material had a higher Vickers hardness (19.27 ± 0.41 kgf/mm2) compared with the milled (18.53 ± 0.32 kgf/mm2) and 3D-printed (17.80 ± 1.85 kgf/mm2) materials, though the difference was statistically significant only between the conventional and 3D-printed groups. The surface roughness of the milled CAD/CAM material (8.80 ± 2.70 nm) was significantly lower than that of the 3D-printed material (24.27 ± 9.82 nm) (p < 0.05).
Conclusion The provisional restorations fabricated using milled PMMA technology provide adequate flexural strength, surface hardness, and low surface roughness, offering a viable alternative for creating provisional restorations.

Authors: Fragkioudakis Ioannis , Batas Leonidas , Vouros Ioannis , Sakellari Dimitra 
Published: December 2024

Abstract
Aim This study aimed to evaluate the diagnostic sensitivity and specificity of the active matrix metalloproteinase-8 (aMMP-8) quantitative chairside point-of-care (PoC) lateral flow immunotest for peri-implant diseases, and it sought to correlate aMMP-8 levels with clinical parameters to determine its effectiveness as a biomarker for peri-implantitis.
Materials and Methods A cross-sectional study was conducted at the Department of Periodontology and Implant Biology, Aristotle University of Thessaloniki, Greece. Participants included systemically healthy individuals with at least one implant loaded for more than 1 year, who had not received periodontal treatment or antibiotics in the preceding 6 months. Exclusion criteria included diabetes and immune-compromising conditions. Peri-implant sulcular fluid (PISF) samples were collected from the mesiobuccal or distobuccal site of the implant. The quantitative chairside PoC lateral flow immunotest for peri-implant diseases (ImplantSafe test) and ORALyzer digital reader were used to analyze PISF, with results expressed in ng/mL. Clinical parameters such as bleeding on probing (BOP), probing depth (PD), recession (REC), and clinical attachment level (CAL) were measured at six sites per implant using a 15-mm scale periodontal probe.
Results No significant differences were found in age, gender distribution, or smoking status between the healthy/mucositis and peri-implantitis groups. The peri-implantitis group showed significantly higher mean percentages of BOP (57.58 ± 31.73 vs. 18.79 ± 24.17), PD (4.59 ± 1.22 mm vs. 2.94 ± 0.78 mm), and CAL (5.21 ± 1.72 mm vs. 3.05 ± 0.81 mm). aMMP-8 levels were also significantly higher in the peri-implantitis group (53.39 ± 49.70 vs. 22.03 ± 32.87). The diagnostic test demonstrated a sensitivity of 81.25% and specificity of 74.07%, with an area under the curve of 79.6%, indicating overall good accuracy in distinguishing between positive and negative conditions.
Conclusion The aMMP-8 is a promising biomarker for peri-implantitis, showing elevated levels in affected patients. The aMMP-8 chairside test demonstrates high diagnostic sensitivity and specificity, supporting its use in early detection and monitoring of peri-implant diseases. Further research is needed to establish standardized protocols for its clinical application and to explore its long-term predictive value in implant care.

Published: December 2024

Abstract
Introduction: The algorithm of multimodal treatment (MMT) of arteriovenous malformations (AVMs) combined with intent-to-cure and presurgery embolization benefits was developed. The aim was to analyze the effectiveness of the MMT compared with unimodal intent-to-cure embolization in patient groups matched concerning clinical and angiographic characteristics.
Methods: A prospective cohort study of MMT effectiveness and safety was performed. To estimate differences in the total occlusion rate and complication rate of MMT compared to unimodal embolization, a 1:1 matched patient group was identified from the Russian Endovascular Neuro Society (RENS) AVM registry using the propensity score matching (EMB group). The treatment outcomes were assessed by the rate of achieving 100% AVM obliteration on follow-up angiography, morbidity, mortality, and the perioperative complication rate.
Results: Complete AVM occlusion was achieved in 93.7% of patients in the MMT group vs 76.2% of patients in the EMB group (p < 0.001). A favorable clinical outcome (mRS = 0–1 at the end of follow-up) was observed in significantly more patients in the MMT group compared with the EMB group (88.9% vs 71.4%, p = 0.024). In the MMT group, the rates of intraoperative and postoperative ischemic complications were comparable to those in the EMB group, and there was a significantly lower rate of postoperative hemorrhagic complications (6.3% vs 20.6%, p = 0.035).
Conclusions: Embolization as the main curative technique of the multimodal algorithm timely followed by microsurgery and radiosurgery ensures the highest clinical and angiographic efficacy of treatment and reduces the rate of disabling postoperative complications.

Published: December 2024

Abstract
Objectives This study aimed to evaluate the expression levels of hypoxia-inducible factor 1-α (HIF-1α) and vascular endothelial growth factor (VEGF) in radicular cysts and periapical granulomas, thereby contributing to the understanding of their potential significance in the differential diagnosis and treatment of these lesions.
Materials and Methods In the present cross-sectional study, 51 samples of periapical lesions were included. Of them, 24 samples were radicular cysts, and 27 samples were periapical granulomas. Samples were immunohistochemically analyzed for HIF-1α and VEGF proteins expression. Chi-square tests and Spearman's rank correlation coefficient tests were used to detect differences and correlations among the parameters, respectively.
Results In radicular cysts, HIF-1α expression was absent in 1 (4.2%), weak in 5 (20.8%), mild in 7 (29.2%), and strong in 11 (45.8%) cases, while VEGF expression was absent in 1 (4.2%), weak in 6 (25.0%), mild in 9 (37.5%), and strong in 8 (33.3%) of the cases; nevertheless, in periapical granulomas, HIF-1α expression was absent in 8 (29.6%), weak in 6 (22.2%), mild in 9 (33.3%), and strong in 4 (14.8%) of the cases, whereas VEGF expression was absent in 4 (14.8%), weak in 16 (59.3%), mild in 4 (14.8%), and strong in 3 (11.1%) of the cases. Chi-square test revealed a significant difference in the expression of HIF-1α and VEGF between radicular cysts and periapical granuloma (chi-square test = 8.906, p = 0.031; chi-square test = 10.401, p = 0.015, respectively). Spearman's correlation test showed a significant correlation between HIF-1α and VEGF in the total samples of both radicular cysts and periapical granulomas (rho = 0.385, p = 0.005).
Conclusion There is high expression of both HIF-1α and VEGF throughout the odontogenic epithelium and connective tissue of the radicular cyst and periapical granuloma. Both HIF-1α and VEGF are more highly expressed in radicular cysts than in periapical granulomas. These findings may aid in the diagnosis and management of suspected periapical lesions, suggesting that radicular cysts exhibit more advanced hypoxic conditions and associated pathways compared with periapical granulomas.

AbstractSchwannomas are mostly benign and solitary tumors that originate from Schwann cells. Macroscopically, they appear as rounded masses with a smooth surface. Schwannomas rarely affect the brachial plexus, accounting for approximately 5% of all cases of schwannomas, presenting a challenge for surgeons. The objective of this article is to describe a case report of a brachial plexus schwannoma in a hospital located in the Northeast of Brazil. A 49-year-old male patient presented pain resulting from the appearance of a left anterior cervical bulging with progressive growth. On physical examination, he had a Medical Research Council (MRC) score of 3 in left arm abduction and paresthesia in the left lateral forearm and arm. On magnetic resonance imaging (MRI), the lesion arises from the C4-C5 junction, measuring 5.9 × 5.4 × 5.5 cm, and the electroneuromyography showed chronic pre-ganglionic involvement of C5 to C7 bilaterally. A left cervicotomy was performed with a horizontal incision at the level of the laryngeal eminence. Brachial plexus lesions with progressive growth tend to be managed surgically. This diagnosis hypothesis should be considered in patients presenting progressive neck bulging in inspection during physical examination. This is an easy and cheap method of suspicion that can be used by health professionals.
Systematizing an Expanded Lumbar Interlaminar Endoscopic Approach: The 10 Steps of Castro-Brock for Increased Security
Authors: Castro João Paulo Souza , Cordenonssi Julianne Tannous , Brock Roger Schmidt 
Published: December 2024

Abstract
Introduction With increasing life expectancy, there is a rising incidence of degenerative spinal pathologies, particularly in the elderly population. Minimally invasive techniques are becoming increasingly attractive due to the higher prevalence of comorbidities in older patients. Endoscopic spine surgery offers advantages such as early rehabilitation, reduced postoperative pain, minimized muscle damage, and shorter hospital stays.
Objectives To enhance the safety of the interlaminar approach and minimize complications, we propose the systematic application of an expanded interlaminar technique, termed the “Castro-Brock technique.” Direct visualization of accurate anatomy is emphasized for successful endoscopic navigation.
Methods The Castro-Brock technique is described in a step-by-step manner, comprising 10 steps with illustrative images. The technique involves an initial puncture on the upper lamina, identification of bony structures, drilling and enlarging the interlaminar bone window, en bloc flavectomy, and precise identification of the descending root before accessing the disc.
Results The Castro-Brock technique facilitates improved visualization of anatomy and provides decompression of neurological structures before disc access. This systematic approach reduces the risk of inadvertent neurological injury and other surgical complications associated with interlaminar access.
Conclusions The Castro-Brock technique represents a valuable addition to the armamentarium of lumbar endoscopic spine surgery. Ensuring meticulous anatomical visualization and pre-disc decompression of neural structures enhances surgical safety and optimizes patient outcomes.
