Visual background information modulates motor contagions in humans
Authors: Saito Hiroto , Fukuchi Kentaro , Inami Masahiko , Ganesh Gowrishankar
Published: August 2024

Motor contagions refer to implicit effects induced by the observation of actions made by others on one’s own actions. A plethora of studies conducted over the last two decades have demonstrated that both observed and predicted actions can induce various kinds of motor contagions in a human observer. However, motor contagions have always been investigated with regard to different features of an observed action, and it remains unclear whether the background environment in which an observed action takes place modulates motor contagions as well. Here, we investigated participant movements in an empirical hand steering task during which the participants were required to move a cursor through a visual channel after being presented with videos of an actor performing the same task. We manipulated the congruency between the actions shown in the video and the background channels and examined whether and how they affected the participants’ own movements. We observed a clear interaction between the observed action and its background. The movement time of the participants’ actions tended to increase or decrease depending on whether they observed a faster or slower movement, respectively, and these changes were amplified if the background was not congruent with the action contained within it. These results suggest that background information can modulate motor contagions in humans.

Cisplatin is the most commonly used platinum-based treatment for nasopharyngeal carcinoma (NPC). However, its clinical application is limited owing to its nephrotoxicity and gastrointestinal reactions. Proton pump inhibitors (PPIs) have been reported to increase nephrotoxicity risk in previous studies. We aimed to evaluate whether PPIs increase cisplatin-induced nephrotoxicity in patients with NPC. In total, 295 patients were included in this prospective cohort study: 145 in the PPIs group and 150 in the non-PPIs group. All patients underwent cisplatin-based induction chemotherapy, followed by cisplatin-based concurrent chemoradiotherapy. The PPIs group received 40 mg of intravenous esomeprazole sodium for 7 days in each chemotherapy cycle. Chi-squared test and logistic regression analyses with odds ratios and 95% confidence intervals were applied to assess the association between PPIs and the risk of acute kidney injury (AKI). AKI incidence in the PPIs group was significantly higher than that in the non-PPIs group (P = 0.005). After adjusting for various confounders including demographic features, clinical features, and renal function indices, PPIs use was significantly associated with a higher AKI risk (odds ratio: 2.775; 95% confidence interval 1.280–6.020; P = 0.010). The incidences of acute and chronic kidney diseases were similar between both groups (P > 0.05), whereas the incidence of nausea was lower in the PPIs group than in the non-PPIs group (P = 0.029). This study has shown that PPIs use may increase the risk of cisplatin-induced acute nephrotoxicity in patients with NPC.
Towards clinical application of freehand optical ultrasound imaging

Published: August 2024

Freehand optical ultrasound (OpUS) imaging is an emerging ultrasound imaging paradigm that uses an array of fibre-optic, photoacoustic ultrasound sources and a single fibre-optic ultrasound detector to perform ultrasound imaging without the need for electrical components in the probe head. Previous freehand OpUS devices have demonstrated capability for real-time, video-rate imaging of clinically relevant targets, but have been hampered by poor ultrasound penetration, significant imaging artefacts and low frame rates, and their designs limited their clinical applicability. In this work we present a novel freehand OpUS imaging platform, including a fully mobile and compact acquisition console and an improved probe design. The novel freehand OpUS probe presented utilises optical waveguides to shape the generated ultrasound fields for improved ultrasound penetration depths, an extended fibre-optic bundle to improve system versatility and an overall ruggedised design with protective elements to improve probe handling and protect the internal optical components. This probe is demonstrated with phantoms and the first multi-participant in vivo imaging study conducted with freehand OpUS imaging probes, this represents several significant steps towards the clinical translation of freehand OpUS imaging.
Effects of biodegradation of starch-nanocellulose films incorporated with black tea extract on soil quality
Authors: Malekzadeh Elham , Tatari Aliasghar , Dehghani Firouzabadi Mohammadreza
Published: August 2024

This study aimed to investigate the biodegradation behaviour of starch/nanocellulose/black tea extract (SNBTE) films in a 30-day soil burial test. The SNBTE films were prepared by mixing commercial starch, nanocellulose (2, 4, and 6%), and an aqueous solution of black tea extract by a simple mixing and casting process. The chemical and morphological properties of the SNBTE films before and after biodegradation were characterized using the following analytical techniques such as field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), and fourier transform infrared (FTIR). The changes in soil composition, namely pH, electrical conductivity (EC), moisture content, water holding capacity (WHC), soil respiration, total nitrogen, weight mean diameter (MDW), and geometric mean diameter (GMD), as a result of the biodegradation process, were also estimated. The results showed that the films exhibited considerable biodegradability (35–67%) within 30 days while increasing soil nutrients. The addition of black tea extract reduced the biodegradation rate due to its polyphenol content, which likely resulted in a reduction in microbial activity. The addition of nanocellulose (2–6% weight of starch) increased the tensile strength, but decreased the elongation at break of the films. These results suggest that starch nanocellulose and SNBTE films are not only biodegradable under soil conditions but also positively contribute to soil health, highlighting their potential as an environmentally friendly alternative to traditional plastic films in the packaging industry.

Published: August 2024

Transglutaminase 2 (TG2) is a GTP-binding, protein-crosslinking enzyme that has been investigated as a therapeutic target for Celiac disease, neurological disorders, and aggressive cancers. TG2 has been suggested to adopt two conformational states that regulate its functions: a GTP-bound, closed conformation, and a calcium-bound, crosslinking-active open conformation. TG2 mutants that constitutively adopt an open conformation are cytotoxic to cancer cells. Thus, small molecules that bind and stabilize the open conformation of TG2 could offer a new therapeutic strategy. Here, we investigate TG2, using static and time-resolved small-angle X-ray scattering (SAXS) and single-particle cryoelectron microscopy (cryo-EM), to determine the conformational states responsible for conferring its biological effects. We also describe a newly developed TG2 inhibitor, LM11, that potently kills glioblastoma cells and use SAXS to investigate how LM11 affects the conformational states of TG2. Using SAXS and cryo-EM, we show that guanine nucleotides bind and stabilize a monomeric closed conformation while calcium binds to an open state that can form higher order oligomers. SAXS analysis suggests how a TG2 mutant that constitutively adopts the open state binds nucleotides through an alternative mechanism to wildtype TG2. Furthermore, we use time resolved SAXS to show that LM11 increases the ability of calcium to bind and stabilize an open conformation, which is not reversible by guanine nucleotides and is cytotoxic to cancer cells. Taken together, our findings demonstrate that the conformational dynamics of TG2 are more complex than previously suggested and highlight how conformational stabilization of TG2 by LM11 maintains TG2 in a cytotoxic conformational state.

Mitochondrial dysregulation plays a significant role in the carcinogenesis. On the other hand, its destabilization strongly represses the viability and metastatic potential of cancer cells. Photodynamic and photothermal therapies (PDT and PTT) target mitochondria effectively, providing innovative and non-invasive anticancer therapeutic modalities. Cyanine dyes, with strong mitochondrial selectivity, show significant potential in enhancing PDT and PTT. The potential and limitations of cyanine dyes for mitochondrial PDT and PTT are discussed, along with their applications in combination therapies, theranostic techniques, and optimal delivery systems. Additionally, novel approaches for sonodynamic therapy using photoactive cyanine dyes are presented, highlighting advances in cancer treatment.

Background

Drugs targeting angiogenesis and immunotherapy have transformed outcomes in renal cancer but may contribute to progressive kidney disease.

Methods

We linked healthcare databases in the West of Scotland (spanning 2010–2020) to identify adults with renal cancer who received one or both classes of drugs. Over two years following initiation, estimated glomerular filtration rate (eGFR) slope was modelled using linear mixed-effects models. Additional renal outcomes used competing risk regression considering the competing risk of death.

Results

Amongst 357 adults (62.5% male; median age 63.0 years, IQI 55.0–71.0), there was no significant change in eGFR (annual eGFR change +1.03 mL/min/1.73 m²/year, 95%CI −1.64 to +3.70), nor in subgroups of patients who had nephrectomy, metastatic cancer or an eGFR < 60 mL/min/1.73 m² prior to systemic therapy. A ≥ 40% decline in eGFR occurred in 82 people (23.0%) within one year of starting systemic therapy and was associated with pre-existing diabetes (subhazard ratio 1.89, 95%CI 1.05–3.41).

Discussion

Anti-angiogenic and immune therapy had no substantial impact on the average change in eGFR but people with diabetes are at higher risk of clinically significant renal events. With appropriate monitoring, more widespread use of these agents in patients with renal impairment may be warranted.

Published: August 2024

The Iowa State University Veterinary Diagnostic Laboratory detected nineteen human-to-swine reverse zoonoses of the 2022–2023 human seasonal H3N2 between November 2022 and November 2023. Cases from seven U.S. locations were detected: 3 Colorado, 1 Illinois, 1 Indiana, 2 Missouri, 7 North Carolina, 1 Ohio, and 1 Pennsylvania. One additional case was detected in Mexico and two cases were identified from Chile. Case samples were comprised of 4 nasal swabs and 15 oral fluids. Virus was successfully isolated from two of four nasal swab samples, but isolation from oral fluids was unsuccessful. The swine detections of H3 human viruses were classified to one of two human-seasonal H3 clades, 3C.2a1b.2a.2b and 3C.2a1b.2a.2a.1. Phylogenetic inference indicated at minimum 7 reverse zoonotic events occurred, with possible swine-to-swine transmission following the initial spillover. Twelve neuraminidase genes were sequenced, and nine were classified as human-seasonal H3N2 lineage: the remaining were endemic swine IAV NA genes from the N2.2002B, N2.1998, or the N1.Classical lineage, suggesting reassortment. The two viral isolates obtained from nasal swab samples were sequenced and were entirely human-lineage viruses. Seven swine samples with human seasonal H3 were sequenced and revealed co-detections with H1 1A.3.3.3 (gamma), with internal gene segments from both the triple reassortant internal gene (TRIG) and pandemic 2009 lineages. Serologic investigation of samples from swine production systems provided evidence for infection with human seasonal H3N2. One farm in the United States and four farms in Mexico had concurrent virologic evidence. The swine-isolated 3C.2a1b.2a.2b H3N2 was antigenically distinct from endemic 1990.4.A, 2010.1, and 2010.2 swine H3N2 lineages, but retained antigenic similarity to a recent human seasonal H3N2 (A/Darwin/6/2021). Pigs experimentally inoculated with a representative isolate demonstrated replication in the nose and lungs and minimal to mild macroscopic and microscopic lung lesions, but primary pigs did not transmit the virus to indirect contacts. If sustained in the pig population, this human seasonal H3 would represent the first new lineage detected in pigs the 2020 decade and present an emerging threat to swine health and production.

Published: August 2024

Human metabolism is complex, and is impacted by genetics, cohabitation, diet, health, and environmental inputs. As such, we applied untargeted LC-MS metabolomics to 1425 saliva samples from a diverse group of elementary school-aged children and their caregivers collected during the Family Life Project, of which 1344 were paired into caregiver/child dyads. We compared metabolomes within and between homes, performed population-wide “metabotype” analyses, and measured associations between metabolites and salivary biomeasures of inflammation, antioxidant potential, environmental tobacco smoke (ETS) exposure, metabolic regulation, and heavy metals. Children and caregivers had similar salivary metabolomes, and dyad explained most metabolomic variation. Our data clustered into two groups, indicating that “metabotypes” exist across large populations. Lastly, several metabolites—putative oxidative damage-associated or pathological markers—were correlated with the above-mentioned salivary biomeasures and heavy metals. Implications of the family environment’s effects on metabolomic variation at population, dyadic, and individual levels for human health are discussed.

Published: August 2024

Massive multiple‐input multiple‐output and non‐orthogonal multiple access (MIMO‐NOMA) with low‐resolution analog‐to‐digital converters (ADCs) have been widely considered for the next‐generation wireless communication systems. However, the performance of the system including power‐scaling law has not been well investigated for the practical low complexity receivers. Employing the additive quantization noise model, we derive asymptotic approximate expressions of the spectrum efficiency for the system with group successive interference cancellation (GSIC) receivers over Rician fading channels. Based on these approximations, we conduct a unified asymptotic analysis for the system with linear, SIC, and GSIC receivers. The analysis reveals the transmission power can be scaled by the number of antennas for the system with GSIC receivers and shows the effects of crucial parameters including the number of groups, resolution bits, and antennas on the performance. Given a quality of service, the minimum data transmission power is also calculated for each user and the corresponding approximate power allocation is derived. The asymptotic analysis and the accuracy of the power allocation approximation are then verified by simulation results. Numerical results also demonstrate that high spectrum efficiency and energy efficiency can be achieved by the system with medium‐resolution ADCs and low complexity maximum ratio combining‐GSIC receivers with a small number of groups.
A compact half‐mode substrate integrated waveguide bandpass filter based on highly confined slow waves with loading capacitive patches
Authors: Wang Ning‐Ning , Zhang De‐Wei , Liu Qing , Qian Hang , Qu Wei‐Zhe
Published: August 2024

A novel slow‐wave half‐mode substrate integrated waveguide (HMSIW) bandpass filter (BPF) is proposed based on spoof surface plasmon polaritons (SSPPs) with loading capacitive patches (LCPs). The bandpass characteristics are achieved by etching complementary SSPPs on the metal patches of the HMSIW. SSPPs exhibit a slow‐wave effect, which effectively reduces the overall size of the filter. At the same time, using proper LCPs between the HMSIW metal via and the complementary SSPPs structure, the effective dielectric constant of the HMSIW can be changed, reducing the low cutoff frequency and further facilitating the miniaturisation of size. A prototype of the proposed filter is designed, fabricated, and measured. The measured results show that the proposed filter has the in‐band insertion loss of 1 and 3 dB passband range of 6.4–9.8 GHz.
Universal domain adaptation for machinery fault diagnosis based on multi‐scale dual attention network and entropy‐based clustering
Authors: Lee Chun‐Yao , Zhuo Guang‐Lin
Published: August 2024

Recently, data‐driven cross‐domain fault diagnosis methods for rotating machinery have been successfully developed. However, most existing diagnostic methods assume that the label spaces of the source and target domains are the same. In practice, the relationship between the label space of the source domain and the target domain is unknown, that is, the universal domain adaptation (UDA) problem. Existing overall domain distribution alignment methods are less effective in facing UDA problems. Thus, this article proposes a deep learning‐based UDA model. First, the proposed model combines multi‐scale learning and dual attention block, which can improve the capability to extract effective features. Then, an entropy optimization strategy is introduced to promote target domain sample clustering without prior knowledge. Finally, the effectiveness of the proposed model is verified on a public dataset of rotating machinery. The results show that the proposed method outperforms six existing cross‐domain fault diagnosis methods.
A localized approximation approach for the calculation of beam shape coefficients of acoustic and ultrasonic Bessel beams
Authors: Ambrosio Leonardo A. , Gouesbet Gérard
Published: August 2024

The description of acoustical waves can be achieved using an expansion over basic functions with weighting coefficients which may be called beam shape coefficients (BSCs). There is a strong analogy between the scalar formalism of acoustical waves and the vectorial electromagnetic formalism, known as generalized Lorenz–Mie theory (GLMT), describing the interaction between a homogeneous sphere and an arbitrary illuminating beam. In particular, BSCs have been introduced as well in GLMT and the mathematical arsenal to evaluate them, developed since several decades, can be used mutatis mutandis to evaluate BSCs in acoustics. In particular, the present paper introduces a method named localized approximation to the evaluation of the acoustical BSCs, similar to the localized approximation used to evaluate electromagnetic BSCs, in the case of Bessel beams. Such a formalism akin to the electromagnetic GLMT may be viewed as an acoustical GLMT and should allow a renewal of the calculation of various properties of acoustical wave scattering, in particular to the design of acoustical tweezers similar to optical tweezers.

Les entéropathies chroniques chez le chien :
diagnostic et traitement
Authors: Blanchot Dominique
Published: August 2024

Les entéropathies chroniques chez le chien se classent en trois groupes : celles qui régressent suite à un changement alimentaire, ou à une antibiothérapie, ou à un traitement immunosuppresseur.
Les index d’activité clinique permettent de mesurer la gravité de la maladie et de suivre l’évolution de celle-ci.
Le traitement des maladies inflammatoires chroniques intestinales est basé essentiellement sur une corticothérapie prolongée sur plusieurs mois, et sur un changement de régime alimentaire et une antibiothérapie.
La supplémentation en vitamine B12 peut être utile en cas de carence. L’apport de prébiotiques et de probiotiques reste controversé sur leur efficacité.
Lors d’entéropathie exsudative, une alimentation hyperdigestible et pauvre en lipides est proposée.
Diagnostic et traitement des corps étrangers intestinaux
Authors: Meige Frédéric
Published: August 2024

Les corps étrangers intestinaux sont des affections fréquemment rencontrées chez les carnivores domestiques. Ils peuvent provoquer une obstruction ou des perforation digestives. Leur diagnostic repose sur l’imagerie.
L’échographie abdominale reste l’examen de choix lors de suspicion d’occlusion intestinale.

Le traitement chirurgical consiste à retirer le corps étranger par entérotomie et à évaluer les lésions intestinales. Si l’intestin est non viable, une entérectomie doit être effectuée.
Le postopératoire consiste à traiter la douleur, surveiller et corriger l’état hydrique et le statut électrolytique de l’animal, et surveiller l’absence d’apparition de complications.
Les principales complications rencontrées lors de chirurgie intestinale sont la péritonite septique, l’iléus et le syndrome de l’intestin court.
Le pronostic lors de corps étranger linéaire est considéré comme moins favorable que lors de corps étranger non linéaire.

Introduction: To prevent infection after limb-sparing surgery for primary malignant bone tumors, it is important to cover the megaprosthesis with muscle tissue that has sufficient blood flow. Coverage with a lateral gastrocnemius flap has been reported in cases of distal femoral replacement in which the vastus lateralis and vastus intermedius muscles have been resected; however, the risk of peroneal nerve palsy is reportedly high because the muscle flap passes near the peroneal head. This study was performed to examine the postoperative outcomes of patients with primary malignant bone tumors of the distal femur who underwent wide resection (including the vastus lateralis and vastus intermedius muscles) followed by reconstruction with a megaprosthesis and coverage of the lateral side of the prosthesis with a sartorius muscle flap. Methods: We retrospectively analyzed three patients who underwent reconstruction with a megaprosthesis after wide resection of a primary malignant bone tumor of the distal femur involving the vastus lateralis and vastus intermedius muscles and reconstruction of the soft tissue defect on the lateral side of the prosthesis with a sartorius muscle flap. Results: The average defect size was 6 × 13 cm, the average time required for a sartorius muscle flap was 100 min, and the average implant coverage was 93%. The average postoperative follow-up period was 35 months, during which no postoperative complications such as infection, skin necrosis, or nerve palsy occurred. Discussion: The distally based sartorius muscle flap is easy to elevate in the supine position, has minimal functional loss after harvesting, and has minimal risk of nerve palsy. It can be advocated as the first option for coverage of soft tissue defects lateral to distal femoral replacement.

Published: August 2024

Ziel der Studie Identifikation von Faktoren, welche postoperative Wundinfektionen bei operativ therapierten neuromuskulären Skoliosen (NMS) beeinflussen und wie diesen präventiv zu begegnen ist.

Material und Methoden Erhoben wurden Daten von 2016–2020 von Patienten mit einer dorsal einzeitig korrigierten NMS mit einem Mindestnachbetrachtungszeitraum von 12 Monaten. Ab Herbst 2018 erfolgte die Verwendung eines perioperativ applizierten epikutanen Vakuumverbands (EV) für 5 Tage. Die postoperative Infektionsrate und das verursachende Keimspektrum wurden analysiert.

Ergebnisse 83 Patienten (m : f 39 : 44) wurden eingeschlossen.
Gruppe 1 (ohne EV) umfasste 48 Patienten, Gruppe 2 (mit EV) 35. Das durchschnittliche Alter
bei OP betrug 16,6 ± 4,94 Jahre. 60 Patienten waren inkontinent, 58 nicht geh- und stehfähig.
Der präoperative Cobb-Winkel der Hauptkrümmung belief sich auf 87,7 ± 18,4°, die pelvic
obliquity auf 18,4 ± 12,25°. Die fusionierte Strecke umfasste 14,59 ± 1,65 Wirbelkörper, bei
einer durchschnittlichen OP-Dauer von 221 ± 49 min. Die OP-Dauer in Gruppe 2 war geringgradig
kürzer (229,92 vs. 216,93 min, p=0,1) ohne einen Unterschied bzgl. der fusionierten Strecke
(14,63 vs. 14,48 Wirbel, p=0,35). Patienten, bei denen eine Wundinfektion auftrat, hatten eine
nicht-signifikant längere Instrumentationsstrecke (15,16 Wirbel, p=0,1) und längere OP-Dauer
(246,2 min, p=0,19). Gruppe 1 wies 7 Infektionen auf (14,5%), davon 4 verursacht durch
Fäkal-Keime, 3 durch Hautkeime. In Gruppe 2 trat keine Infektion auf (p<0,05). Patienten
mit einer Infektion wurden 3-mal ± 1,2-mal revidiert. Die Dauer der postoperativ notwendigen
intensivmedizinischen Behandlung stieg bei Infektion von 80,6 ± 132,7 auf 457,6 ± 315,8 h
(p<0,05), der stationäre Aufenthalt verlängerte sich von 14,31 ± 5,65 d auf 34,3 ± 21,6 d
(p<0,05). Es wurde eine antiinfektive Therapie über 56,1 ± 28,58 d verabreicht (16,3 ± 8,7
d i.v., 39,8 ± 24,4 d p.o.).

Schlussfolgerung Die Verwendung eines epikuanten Vakuumverbandes für 5 Tage nach operativer Korrektur einer NMS reduziert die Rate von Wundinfektionen signifikant.
Lokaltherapie im Stadium IV bei Oligopersistenz oder Progression
Authors: Schulz Christian
Published: August 2024

Oligopersistenz und Oligoprogress stellen definierte Situationen des metastasierten Lungenkarzinoms dar. Oligopersistenz bedeutet das Verbleiben weniger Metastasen unter einer wirksamen Systemtherapie. Unter Oligoprogress versteht man eine weitgehend kontrollierte Tumorerkrankung mit einigen Metastasen, die einen erneuten Progress aufweisen. In der Situation Oligopersistenz soll durch ergänzende lokal ablative Maßnahmen aller verbliebenen Läsionen eine vollständige Tumorkontrolle mit Verbesserung der Prognose bis zur Heilung erzielt werden. In der Situation Oligoprogress zielen lokal ablative Maßnahmen darauf ab, erneut eine vollständige Kontrolle der Tumorerkrankung unter Fortführung der etablierten Systemtherapie herzustellen. Die Konzepte gehen auf Überlegungen zurück, die bereits vor mehr als 30 Jahren unter dem Begriff der Oligometastasierung von Hellman und Weichselbaum in der Onkologie eingeführt wurden. Insbesondere durch zielgerichtete Therapien des molekular
alterierten Lungenkarzinoms und Chemo-Immuntherapie-Regime mit hohen Ansprechraten und langer Ansprechdauer haben multimodale Therapiekonzepte in der Situation der Oligopersistenz und Oligoprogression an Bedeutung gewonnen. Es wird die verfügbare Evidenz dargelegt und durch Fallbeispiele aus dem eigenen Zentrum ergänzt.
