Gamma-aminobutyric acid improves wheat seed germination under salinity and heat stress
Authors: Yu Song , Lian Zhihan , Yu Lihe , Guo Wei , Zhang Chunyu , Zhang Yifei 
Published: September 2023

Abstract
High abiotic stress can decrease germination rate (GR), whereas low salinity or heat stress can enhance GR. Under the dual stress conditions of salinity (50 mM NaCl) and high temperature (35°C), the influence of gamma-aminobutyric acid (GABA) on wheat seed germination was examined. Low salinity (50 mM NaCl) arrested GR at high temperatures (35°C), whereas exogenous GABA improved GR under combined salinity (50 mM NaCl) and high temperature (35°C) stress. Additionally, improved seed germination associated with GABA could be attenuated by abscisic acid (ABA), dimethylthiourea (a reactive oxygen species [ROS] scavenger), and diphenyliodonium or imidazole (two NADPH oxidase inhibitors). Conversely, GABA-enhanced germination could be improved further by H2O2, diethyldithiocarbamic acid (a superoxide dismutase [SOD] inhibitor), aminotriazole (a catalase [CAT] inhibitor), fluridone (an ABA inhibitor), or gibberellin. In addition, GABA reversed the reduced H2O2 and enhanced ABA accumulation in wheat seeds, and GABA accumulation and glutamate decarboxylase activities were improved by exogenous GABA. Inhibited SOD and CAT activities were potentially reversed by GABA via the upregulation of MnSOD and CAT expression levels. According to the results, elevated antioxidant enzyme activities and ROS mediated by NADPH oxidase are essential for enhancing wheat seed germination through the application of GABA under the conditions of combined salt and high-temperature stress.

Published: September 2023

Abstract

Google proposed a new TCP congestion control algorithm based on Bottleneck Bandwidth and Round-trip propagation time (BBR). BBR achieves high transmission rate and low latency by estimating the available bottleneck capacity. Compared with the traditional loss-based congestion control algorithms such as CUBIC, BBR has obvious advantages in throughput. However, some studies have found that BBR has poor fairness among flows with different Round Trip Times (RTTs), inter-protocol unfairness and high packet loss rate in shallow buffer. BBR is already used in some cases, so its fairness and practicability improvements become very important. In this paper, the fairness of BBR is taken as the breakthrough point to deeply analyze the bandwidth probe mechanism. The pacing rate control model is derived and the effect of pacing gain on BBR performance is revealed. Furthermore, This paper proposes a BBR-PG algorithm, which adjusts pacing gain based on RTT to improve BBR. Simulation and real network experiments show that the proposed algorithm improves RTT fairness and inter-protocol fairness, reduces the retransmission rate,while retaining the throughput advantage of the original BBR.

Published: September 2023

Abstract
Inwardly rectifying potassium channels (Kir) allow potassium (K+) to easily move into cells. They are implicated in several diverse physiological processes throughout the body. KCNJ16 associated tubulopathy and deafness affects a subset of Kir transport channels. This disease was first described in 2021, amongst a cohort of 9 patients in total.
Sudden cardiac arrest has been described as a presenting symptom of tubulopathy previously. We report the case of an infant who presented with sudden cardiac arrest (SCA) aged 7 months secondary to severe hypokalaemia. Singleton exome analysis identified apparent homozygous missense variants in KCNJ16 (c.409C>G; p.R137G). To our knowledge, this is the first description of sudden cardiac arrest at presentation in this form of tubulopathy.
Cross-Attention Multi-Scale Spatial Temporal Transformer for Skeleton-based Action Recognition
Authors: Lin Zhehuang , Gao Yichang , Li Dong 
Published: September 2023

Abstract

In recent years, TransFormer has made remarkable achievements in a variety of tasks in computer vision. However, the Transformer-based methods have limitations in learning multi-scale features of skeleton data, while the multi-scale spatial temporal features contain potential both global and local information, which is crucial for skeleton-based action recognition.In this work, we explore the multi-scale feature representation of skeleton sequence in both the spatial and temporal dimensions, and propose an efficient cross-attention mechanism for cross-scale feature fusion. Moreover, we propose a Multi-scale Feature Extraction and Fusion Transformer (MFEF-Former) , which can be divided into two types: (1) MFEF-SFormer for spatial modeling, which captures the inter-joint and inter-part correlations with self-attention, then performs multi-scale spatial feature fusion with cross-attention to model the correlations between joints and body parts. (2) MFEF-TFormer for temporal modeling, which captures the multi-scale temporal feature with self-attention and fuses the multi-scale feature with cross-attention. These two components are combined in a two-stream network, which is evaluated on two large-scale datasets, NTU RGB+D and NTU RGB+D 120. The experiments show that our proposed method outperforms other Transformer-based methods on skeleton-based action recognition and achieves state-of-the-art performance.

Abstract

Background:Deep learning image reconstruction (DLIR) is a novel computed tomography (CT) reconstruction technique that minimizes image noise, enhances image quality, and enables radiation dose reduction. This study aims to compare the diagnostic performance of DLIR and iterative reconstruction (IR) in the evaluation of focal hepatic lesions.Methods:We conducted a retrospective study of 216 focal hepatic lesions in 109 adult participants who underwent abdominal CT scanning at our institution. We used DLIR (low, medium, and high strength) and IR (0%, 10%, 20%, and 30%) techniques for image reconstruction. Four experienced abdominal radiologists independently evaluated focal hepatic lesions based on five qualitative aspects (lesion detectability, lesion border, diagnostic confidence level, image artifact, and overall image quality). Quantitatively, we measured and compared the level of image noise for each technique at the liver and aorta.Results:There were significant differences (p< .001) among the seven reconstruction techniques in terms of lesion borders, image artifacts, and overall image quality. Low-strength DLIR (DLIR-L) exhibited the best overall image quality. Although high-strength DLIR (DLIR-H) had the least image noise and fewest artifacts, it also had the lowest scores for lesion borders and overall image quality. Image noise showed a weak to moderate positive correlation with participants’ body mass index and waist circumference.Conclusions:The optimal-strength DLIR significantly improved overall image quality for evaluating focal hepatic lesions compared to the IR technique. DLIR-L achieved the best overall image quality while maintaining acceptable levels of image noise and quality of lesion borders.

Abstract

BackgroundCyanoacrylate adhesive closure (CAC) systems have become widely used in the treatment of varicose veins. In terms of efficacy and safety, these non-thermal non-tumescent methods have been reported to be noninferior to endovenous thermal ablation techniques. There are no known published studies that compare products using CAC. VenaSeal® (Medtronic, Santa Rosa, Ca, USA) and VenaBlockⓇ (Invamed, Ankara, Turkey) are among the most commonly used CAC-based products worldwide. This review article focuses on the efficacy and safety of these two different commonly used products.MethodsPublished full-text research articles regarding the VenaBlock®System or the VenaSealⓇSystem was searched. Data for each product were evaluated by comparing them with each other in terms of effectiveness and safety.ResultsA total of 1882 extremities from 11 studies with VenaBlock®and 524 extremities from 8 studies with VenaSealⓇwere included and compared. Both devices were observed to be effective and cumulative recanalization-free survival rates were similar (p = 0.188) at the 6th, 12th, 24th, 36th and 60th month follow-ups. Both products were found to improve VCSS and QoL scores.ConclusionBoth devices were effective in terms of cumulative recanalization-free survival rates. Both significantly improved the venous clinical severity score and the quality of life scores. Cyanoacrylate adhesive closure is feasible in varicose vein treatment.

Abstrak: Penelitian ini bertujuan untuk mengetahui bagaimana metode pembelajaran tentang Bahasa Arab yang digunakan disalah satu pondok pesantren yang ada di Lombok, yakni pondok pesantren Nurul Hakim, Kediri. Metode yang kami gunakan dalam artikel ini adalah metode kualitatif dengan teknik observasi dari salah satu alumni pondok pesantren Nurul Hakim, Kediri. Kemudian hasil yang kami dapatkan adalah tidak jauh perbedaannya dari pondok-pondok pesantren tradisional atau modern lainnya, yang mewajibkan para santri untuk berkomunikasi menggunakan Bahasa Arab. Pondok pesantren Nurul Hakim lebih mengedepankan berkomunikasi menggunakan Bahasa Arab daripada mempelajari gramatikal dalam Bahasa Arab seperti Nahwu dan Shorof. Melalui mufrodat, hiwar dan pembelajaran yang lainnya menjadi alat untuk mereka gunakan dalam berkomunikasi setiap hari. Ketika mereka berbicara menggunakan bahasa Indonesia atau bahasa daerah, justru hal tersebut akan menyebabkan mereka mendapatkan sanki yang berlaku di pondok pesantren tersebut namun masih banyak ternyata yang menggunakan bahasa daerah di belakang para mudabbir/mudabbiroh, namun mereka tetap dikenakan sanki karena ada yang selalu mengawasi mereka setiap hari.

Authors: Patlasari Mira , Retnaningdyah Pratiwi , Setiawan Slamet 
Published: September 2023

Although professional identity formation is a key idea in education, little is known about the procedure from the viewpoint of the students. The goal of this study is to evaluate the limitations of the metaphors used by Indonesian first-graders studying education to characterize teachers in the context of developing a professional identity. Both qualitative and quantitative analyses of the data were done. Four conceptual themes were comprised of a total of 39 well-articulated metaphorical pictures. Despite some restrictions, the use of metaphors to create and explain professional identities can be useful in reflecting the values and beliefs of matriculating to education school, as well as in providing some insight into the personal beliefs and values of matriculating assistance with and suggestions for curriculum conception.

Three-stage correction of severe idiopathic scoliosis with limited skeletal traction during a humanitarian surgical mission: illustrative case
Authors: Sarmiento J. Manuel , Fakhoury Jordan , Singh Angadh , Hawk Cameron , Sethi Khalid , Bains Ravi 
Published: September 2023

BACKGROUND
Underprivileged and underserved patients from developing countries often present late with advanced, untreated spinal deformities. We report a three-stage all-posterior approach using limited skeletal traction with Gardner-Wells tongs (GWTs) for the management of severe idiopathic scoliosis during a humanitarian surgical mission trip.

OBSERVATIONS
A 17-year-old high-school female was previously diagnosed with juvenile idiopathic scoliosis (diagnosed at age 8) and progressed to a severe 135° kyphoscoliosis. Procedural stage 1 involved spinal instrumentation and posterior releases via posterior column osteotomies from T3 to L4. She then underwent 7 days of skeletal traction with GWTs in the intensive care unit as stage 2. In stage 3, rod engagement, posterior spinal fusion, and partial T10 vertebral column resection were performed. There were no changes in intraoperative neuromonitoring during either surgery and she woke up neurologically intact after both stages of the surgical procedure.

LESSONS
Skeletal traction with GWTs is a viable alternative to traditional halo-gravity traction in settings with limited resources. Three-stage spinal deformity correction using limited skeletal traction is a feasible and effective approach for managing severe scoliosis during humanitarian surgical mission trips.
The Euler–Poisswell/Darwin equation and the asymptotic hierarchy of the Euler–Maxwell equation
Authors: Möller Jakob , Mauser Norbert J. 
Published: September 2023

In this paper we introduce the (unipolar) pressureless Euler–Poisswell equation for electrons as the [Formula: see text] semi-relativistic approximation and the (unipolar) pressureless Euler–Darwin equation as the [Formula: see text] semi-relativistic approximation of the (unipolar) pressureless Euler–Maxwell equation. In the “infinity-ion-mass” limit, the unipolar Euler–Maxwell equation arises from the bipolar Euler–Maxwell equation, describing a coupled system for a plasma of electrons and ions. The non-relativistic limit [Formula: see text] of the Euler–Maxwell equation is the repulsive Euler–Poisson equation with electric force. We propose that the Euler–Poisswell equation, where the Euler equation with electric force is coupled to the magnetostatic [Formula: see text] approximation of Maxwell’s equations, is the correct semi-relativistic [Formula: see text] approximation of the Euler–Maxwell equation. In the Euler–Poisswell equation the fluid dynamics are decoupled from the magnetic field since the Lorentz force reduces to the electric force. The first non-trivial interaction with the magnetic field is at the [Formula: see text] level in the Euler–Darwin equation. This is a consistent and self-consistent model of order [Formula: see text] and includes the full Lorentz force, which is relativistic at [Formula: see text]. The Euler–Poisswell equation also arises as the semiclassical limit of the quantum Pauli–Poisswell equation, which is the [Formula: see text] approximation of the relativistic Dirac–Maxwell equation. We also present a local wellposedness theory for the Euler–Poisswell equation. The Euler–Maxwell system couples the non-relativistic Euler equation and the relativistic Maxwell equations and thus it is not fully consistent in [Formula: see text]. The consistent fully relativistic model is the relativistic Euler–Maxwell equation where Maxwell’s equations are coupled to the relativistic Euler equation – a model that is neglected in the mathematics community. We also present the relativistic Euler–Darwin equation resulting as a [Formula: see text] approximation of this model.
