Preparatory attention to visual features primarily relies on non-sensory representation
Authors: Gong Mengyuan , Chen Yilin , Liu Taosheng
Published: December 2022

Prior knowledge of behaviorally relevant information promotes preparatory attention before the appearance of stimuli. A key question is how our brain represents the attended information during preparation. A sensory template hypothesis assumes that preparatory signals evoke neural activity patterns that resembled the perception of the attended stimuli, whereas a non-sensory, abstract template hypothesis assumes that preparatory signals reflect the abstraction of attended stimuli. To test these hypotheses, we used fMRI and multivariate analysis to characterize neural activity patterns when human participants were prepared to attend a feature and then select it from a compound stimulus. In an fMRI experiment using basic visual feature (motion direction), we observed reliable decoding of the to-be-attended feature from the preparatory activity in both visual and frontoparietal areas. However, while the neural patterns constructed by a single feature from a baseline task generalized to the activity patterns during stimulus selection, they could not generalize to the activity patterns during preparation. Our findings thus suggest that neural signals during attentional preparation are predominantly non-sensory in nature that may reflect an abstraction of the attended feature. Such a representation could provide efficient and stable guidance of attention.

Published: December 2022

Cardiovascular magnetic resonance (CMR) plays an important clinical role for diagnosis and therapy monitoring of cardiac amyloidosis (CA). Previous data suggested a lower native T1 value in spite of a higher LV mass and higher extracellular volume fraction (ECV) value in wild-type transthyretin amyloidosis (ATTRwt) compared to light-chain amyloidosis (AL)—resulting in the still unsolved “native T1 vs. ECV paradox” in CA. The purpose of this study was to address this paradox. The present study comprised N = 90 patients with ATTRwt and N = 30 patients with AL who underwent multi-parametric CMR studies prior to any specific treatment. The CMR protocol comprised cine- and late-gadolinium-enhancement (LGE)-imaging as well as T2-mapping and pre-/post-contrast T1-mapping allowing to measure myocardial ECV. Left ventricular ejection fraction (LV-EF), left ventricular mass index (LVMi) and left ventricular wall thickness (LVWT) were significantly higher in ATTRwt in comparison to AL. Indexed ECV (ECVi) was also higher in ATTRwt (p = 0.041 for global and p = 0.001 for basal septal). In contrast, native T1- [1094 ms (1069–1127 ms) in ATTRwt vs. 1,122 ms (1076–1160 ms) in AL group, p = 0.040] and T2-values [57 ms (55–60 ms) vs. 60 ms (57–64 ms); p = 0.001] were higher in AL. Considering particularities in myocardial density, “total extracellular mass” (TECM) was substantially higher in ATTRwt whereas “total intracellular mass” (TICM) was rather similar between ATTRwt and AL. Consequently, the “ratio TICM/TECM” was lower in ATTRwt compared to AL (0.58 vs. 0.83; p = 0.007). Our data confirm the presence of a “native T1 vs. ECV paradox” with lower native T1 values in spite of higher myocardial mass and ECV in ATTRwt compared to AL. Importantly, this observation can be explained by particularities regarding myocardial density that result in a lower TICM/TECM “ratio” in case of ATTRwt compared to AL—since native T1 is determined by this ratio.
Functionalized graphene/polystyrene composite, green synthesis and characterization
Authors: Farouq Rania
Published: December 2022

A composite of sulfonated waste polystyrene (SWPS) and graphene oxide was synthetized by an inverse coprecipitation in-situ compound technology. Polystyrene (PS) has a wide range of applications due to its high mechanical property. the graphene were incorporated into sulfonated polystyrene (SPS) to improve the thermal stability and mechanical performance of the composites. Functionalized graphene were synthesized with tour method by using recovered anode (graphite) of dry batteries while sulfonated waste expanded polystyrene was obtained through sulfonation of the polymer. The SPS and GO + SPS composite were characterized using by Fourier Transform Infrared spectroscopy (FT-IR) and transmission electron microscopy (TEM). While the degree of sulfonation (DS) was determined through elemental analysis. The results show the degree of sulfonation of the composite is 23.5% and its ion exchange capacity is 1.2 meq g−1. TEM analysis revealed that the GO particles were loaded on the surface of sulphonated polystyrene and that the SWPS was intercalated into the sub-layers of nanoG homogeneously, which result in an increase in electrical conduction.

Sharp dose gradients and high biological effectiveness make ions such as 12C an ideal tool to treat deep-seated tumors, however, at the same time, sensitive to errors in the range prediction. Tumor safety margins mitigate these uncertainties, but during the irradiation they lead to unavoidable damage to the surrounding healthy tissue. To fully exploit the Bragg peak benefits, a large effort is put into establishing precise range verification methods. Despite positron emission tomography being widely in use for this purpose in 12C therapy, the low count rates, biological washout, and broad activity distribution still limit its precision. Instead, radioactive beams used directly for treatment would yield an improved signal and a closer match with the dose fall-off, potentially enabling precise in vivo beam range monitoring. We have performed a treatment planning study to estimate the possible impact of the reduced range uncertainties, enabled by radioactive 11C ions treatments, on sparing critical organs in tumor proximity. Compared to 12C treatments, (i) annihilation maps for 11C ions can reflect sub- millimeter shifts in dose distributions in the patient, (ii) outcomes of treatment planning with 11C significantly improve and (iii) less severe toxicities for serial and parallel critical organs can be expected.
Theoretical analysis and simulation calculation of hydrodynamic pressure pulsation effect and flow induced vibration response of radial gate structure
Authors: Zhang Bozhi , Jing Xiaochuan
Published: December 2022

This work aims to explore the characteristics of stochastic fluctuant water pressure acted on the surface of large radial gate, and to investigate the flow-induced vibration response of the whole radial gate structure. The finite element calculation model structure of the radial gate is established by taking a large-scale radial gate as prototype to discuss the hydrodynamic pressure acting on the gate leaf with different opening, analyze the dynamic pressure time curves, and achieve the flow-induced vibration response by deeming hydrodynamic pressure as dynamic load. When taking 10% opening of the radial gate, the results indicate that the hydrodynamic pressure distributed on the arc surface of the radial gate changes with the flow conditions, with the maximum pressure occurred at the center of the lower edge of the gate leaf. One point in the time history curve of fluctuating water pressure can be taken as the dynamic load for the flow-induced vibration analysis. The flow-induced vibration responses at the monitoring point of the radial gate structure show periodic changes in the X, Y, and Z directions. The finite element simulation results agree well with the theoretical calculation results, so reference can be provided for the hydrodynamic pressure testing and the flow-induced vibration response calculations.

Published: December 2022

Acute thoracic aortic dissection is a life-threatening disease, in which blood leaking from the damaged inner layer of the aorta causes dissection between the intimal and adventitial layers. The diagnosis of this disease is challenging. Chest x-rays are usually performed for initial screening or diagnosis, but the diagnostic accuracy of this method is not high. Recently, deep learning has been successfully applied in multiple medical image analysis tasks. In this paper, we attempt to increase the accuracy of diagnosis of acute thoracic aortic dissection based on chest x-rays by applying deep learning techniques. In aggregate, 3,331 images, comprising 716 positive images and 2615 negative images, were collected from 3,331 patients. Residual neural network 18 was used to detect acute thoracic aortic dissection. The diagnostic accuracy of the ResNet18 was observed to be 90.20% with a precision of 75.00%, recall of 94.44%, and F1-score of 83.61%. Further research is required to improve diagnostic accuracy based on aorta segmentation.

Published: December 2022

Availability of a contiguous chromosome-level genome assembly is the foundational step to develop genome-based studies in American mink (Neogale vison). The main objective of this study was to provide a high quality chromosome-level genome assembly for American mink. An initial draft of the genome assembly was generated using 2,884,047 PacBio long reads. Integration of Hi-C data into the initial draft led to an assembly with 183 scaffolds and scaffold N50 of 220 Mb. This gap-free genome assembly of American mink (ASM_NN_V1) had a length of 2.68 Gb in which about 98.6% of the whole genome was covered by 15 chromosomes. In total, 25,377 genes were predicted across the American mink genome using the NCBI Eukaryotic Genome Annotation Pipeline. In addition, gene orthology, demographic history, synteny blocks, and phylogenetic relationships were studied in connection with the genomes of other related Carnivora. Furthermore, population-based statistics of 100 sequenced mink were presented using the newly assembled genome. Remarkable improvements were observed in genome contiguity, the number of scaffolds, and annotation compared to the first draft of mink genome assembly (NNQGG.v01). This high-quality genome assembly will support the development of efficient breeding strategies as well as conservation programs for American mink.
Machine learning for flow-informed aerodynamic control in turbulent wind conditions
Authors: Renn Peter I. , Gharib Morteza
Published: December 2022

Control of aerodynamic forces in gusty, turbulent conditions is critical for the safety and performance of technologies such as unmanned aerial vehicles and wind turbines. The presence and severity of extreme flow conditions are difficult to predict, and explicit modeling of fluid dynamics for control is not feasible in real time. Model-free reinforcement learning methods present an end-to-end control solution for nonlinear systems as they require no prior knowledge, can easily integrate different types of measurements, and can adapt to varying conditions through interaction. Here, we show that reinforcement learning methods can achieve effective aerodynamic control in a highly turbulent environment. Algorithms are trained with different neural network structures, and we find that reinforcement learning agents with recurrent neural networks can effectively learn the nonlinear dynamics involved in turbulent flows and strongly outperform conventional linear control techniques. We also find that augmenting state observations with measurements from a set of bioinspired flow sensors can improve learning stability and control performance in aerodynamic systems. These results can serve to inform future gust mitigation systems for unmanned aerial vehicles and wind turbines, enabling operation in previously prohibitively dangerous conditions.

The role of the γ subunit in the photosystem of the lowest-energy phototrophs
Authors: Namoon Dowrung , Rudling Nicola M. , Canniffe Daniel P.
Published: December 2022

Purple phototrophic bacteria use a ‘photosystem’ consisting of light harvesting complex 1 (LH1) surrounding the reaction centre (RC) that absorbs far-red–near-infrared light and converts it to chemical energy. Blastochloris species, which harvest light >1000 nm, use bacteriochlorophyll b rather than the more common bacteriochlorophyll a as their major photopigment, and assemble LH1 with an additional polypeptide subunit, LH1γ, encoded by multiple genes. To assign a role to γ, we deleted the four encoding genes in the model Blastochloris viridis. Interestingly, growth under halogen bulbs routinely used for cultivation yielded cells displaying an absorption maximum of 825 nm, similar to that of the RC only, but growth under white light yielded cells with an absorption maximum at 972 nm. HPLC analysis of pigment composition and sucrose gradient fractionation demonstrate that the white light-grown mutant assembles RC–LH1, albeit with an absorption maximum blue-shifted by 46 nm. Wavelengths between 900–1000 nm transmit poorly through the atmosphere due to absorption by water, so our results provide an evolutionary rationale for incorporation of γ; this polypeptide red-shifts absorption of RC–LH1 to a spectral range in which photons are of lower energy but are more abundant. Finally, we transformed the mutant with plasmids encoding natural LH1γ variants and demonstrate that the polypeptide found in the wild type complex red-shifts absorption back to 1018 nm, but incorporation of a distantly related variant results in only a moderate shift. This result suggests that tuning the absorption of RC–LH1 is possible and may permit photosynthesis past its current low-energy limit.

Authors: Shibayama Jun , Kawahara Akira , Yamauchi Junji , Nakano Hisamatsu
Published: December 2022

The finite‐difference time‐domain (FDTD) method based on the iterated Crank–Nicolson (ICN) scheme is extended to a frequency‐dependent version. The Drude model is used to express a metal dispersion, which is incorporated into the iterated Crank–Nicolson formulation with the trapezoidal recursive convolution technique. The validity of the present finite‐difference time‐domain method with convolutional perfectly matched layers is discussed through the analysis of a metal‐insulator‐metal plasmonic waveguide. Numerical results obtained from a two‐iteration technique are found to agree well with those from the traditional explicit finite‐difference time‐domain method.

Authors: Zhang Dabo , Chu Zhuwei , Gui Qianjin , Wu Fan , Yang Hejun , Ma Yinghao , Tao Weiqing
Published: December 2022

Equipment maintenance decision is a very critical technology in power grid asset management. The traditional maintenance decision focuses on the analysis of the operation performance of the equipment itself, but lacks the analysis and description of the fuzziness of power equipment outage parameters. Therefore, this paper establishes the reliability assessment model based on equipment health condition monitoring, which makes the maintenance decision transition from equipment level to system level, and the fuzzy mathematics theory is introduced to establish a model describing the fuzziness of equipment failure rate parameter to make system reliability assessment and equipment maintenance decision scheme. Firstly, this paper proposes a fuzzy failure rate model of power transformer based on condition monitoring. Then the fuzzy parameters are combined with the conventional probabilistic reliability assessment method to establish the fuzzy probability hybrid reliability assessment model of the transmission system, and the fuzzy maintenance reliability benefit index is defined and deduced. Finally, a maintenance strategy of transformer based on fuzzy probability hybrid reliability assessment and fuzzy set theory is proposed, and the case study is carried out on a regional power grid in East China. The results show that the proposed model provides an improved maintenance strategy of power equipment.
Novel synchronous rectification strategy for flyback converter in both DCM and CCM applications
Authors: Sun Shikai , Guo Hui , Zhang Yimeng , Sun Lejia , Li Yufei , Zhang Yuming
Published: December 2022

In this paper, a novel flyback synchronous rectification (SR) strategy for both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) is proposed. The hybrid mode is suitable for the wide input voltage range, and large load range, which can widen the application range. The proposed strategy can reduce the body diode conduction time in the turning‐on interval in both the DCM and CCM and eliminate the cross‐conduction between the primary switch and secondary switch that existed in the conventional CCM SR converter by adding several logic units. A 12‐V/3‐A output mixed‐mode flyback converter prototype is designed and fabricated to verify the strategy. Measurement results show that with the proposed SR strategy, the efficiency is improved by approximately 5.5% in CCM and 0.5% in DCM.
Gaussian‐like measurement likelihood based particle filter for extended target tracking
Authors: Liu Yiduo , Ji Hongbing , Zhang Yongquan
Published: December 2022

Extended target tracking based on the star‐convex model is a multi‐dimensional nonlinear estimation problem. To approximate the shape of an extended target, the star‐convex model requires a higher‐order Fourier series expansion, which will increase the dimensionality of the extended state, so that the nonlinear filters under Gaussian assumptions cannot converge to the optimal state estimation. In this paper, a novel particle filter algorithm based on Gaussian‐like measurement likelihood (GL) is proposed. As latent variables with high uncertainty in the measurement model, the scattering centres are modelled as a Gaussian‐like probability distribution characterising the target's shape. Then the measurement noise is integrated into the Gaussian‐like probability distribution via Gaussian quadrature to obtain the accurate measurement likelihood. Moreover, particle swarm optimization is employed to reduce computational complexity. It enables particles to move into the vicinity of measurements, thereby increasing the diversity of the particles belonging to the target's shape. The simulation results show that the GL can improve the accuracy of shape estimation under high measurement noise and low measurement rates. Furthermore, the proposed particle filter can track the extended target effectively with an aeroplane‐like shape.
Revision of the systematics of the Polystomoidinae (Platyhelminthes, Monogenea, Polystomatidae) with redefinition of Polystomoides Ward, 1917 and Uteropolystomoides Tinsley, 2017
Authors: Chaabane Amira , Du Preez Louis , Johnston Gerald R. , Verneau Olivier
Published: December 2022

Polystomatids are platyhelminth parasites that infect mainly amphibians and freshwater turtles. For more than seven decades, chelonian polystomes were classified into three genera according to the number of hamuli, i.e. absent for Neopolystoma, one pair for Polystomoidella and two pairs for Polystomoides. Following re-examination of morphological characters, seven new genera were erected the past six years, namely Apaloneotrema, Aussietrema, Fornixtrema, Manotrema, Pleurodirotrema, Uropolystomoides and Uteropolystomoides. However, the polyphyly of Neopolystoma and Polystomoides on the one hand, and the nested position of Uteropolystomoides within a clade encompassing all Neopolystoma and Polystomoides spp. on the other, still raised questions about the validity of these genera. We therefore re-examined several types, paratypes and voucher specimens, and investigated the molecular phylogeny of polystomes sampled from the oral cavity of North American turtles to re-evaluate their systematic status. We show that all Polystomoides Ward, 1917, sensu Du Preez et al., 2022, Neopolystoma Price, 1939, sensu Du Preez et al., 2022 and Uteropolystomoides Tinsley, 2017 species, display vaginae that are peripheral and extend well beyond the intestine. We thus reassign all species of the clade to Polystomoides and propose nine new combinations; however, although Uteropolystomoides is nested within this clade, based on its unique morphological features, we propose to keep it as a valid taxon. Polystomoides as redefined herein groups all polystome species infecting either the oral cavity or the urinary bladder of cryptodires, with peripheral vaginae and with or without two pairs of small hamuli. Uteropolystomoides nelsoni (Du Preez & Van Rooyen 2015), originally described from Pseudemys nelsoni Carr is now regarded as Uteropolystomoides multifalx (Stunkard, 1924) n. comb. infecting three distinct Pseudemys species of North America.

Research on Domestic and Foreign Small and Medium-sized Enterprises’ Listing Demand and Entitlement Based on Financial Perspective
Authors: Yu Fenghao
Published: December 2022

Small and medium-sized enterprises (SMEs) generally have the problems of single financing channel and shortage of funds. It has become a new economic hot spot for SMEs to raise funds by listing on growth enterprises market (GEM). However, due to the characteristics of small-scale and high growth of SMEs, which attach importance to development and have low requirements for the quality of financial information, many SMEs have many financial problems in listing and reporting. Corporate governance structure can be understood from the narrow and broad perspectives. From the narrow perspective, corporate governance structure is a system of managing and controlling companies. Corporate governance in a broad sense includes not only some aspects of corporate governance in a narrow sense, but also human resource management, income distribution incentive system, financial system, corporate culture and other systems related to the top management control of enterprises. From the financial perspective, this paper studies the listing demand and due rights of SMEs at home and abroad.

Authors: Wang Yubo
Published: December 2022

What is the impact of the COVID-19 on China’s economy? After using the linear regression to analyze the data of GDP, national fiscal revenue and the added value of nine major industries, we find that the COVID-19 had a great impact on China’s economy in 2020 but not in 2021. Then, we use the principal component analysis to reduce the dimension of data and define a new variable to represent China’s economy, which is called “Chinese economic quantity”. It can well describe China’s economy, which has the same function as GDP. By comparing its changes in different years, it can verify the influence on China’s economy. Finally, some suggestions and advices will be given.
Risk Logic and Policy Enlightenment of Real Estate Bubble and Financial Crisis
Authors: Xiong Hanfei
Published: December 2022

With the rapid growth of economy, residents’ demand for real estate is not only limited to residential function, but also as an important investment product to buy. Therefore, under the joint action of these two demands, the real estate prices in China have increased rapidly. At present, the predicament of the real estate industry, especially the fluctuation of house prices, can easily cause the illusion that the real estate bubble is squeezed out or reduced, thus neglecting to guard against it and causing great disaster. Both the expansion and bursting of bubbles will lead to wealth transfer and social stratification, and the resulting political risks are more likely to lead to market panic or even financial crisis than financial risks. This paper analyzes the relationship between China’s real estate industry and financial industry, and then puts forward some policy suggestions to prevent the financial crisis caused by the real estate bubble in China.
Evaluation of Current Environmental Kuznets Curve Model with New Indicators
Authors: Liu Yuang
Published: December 2022

The Environmental Kuznets Curve was introduced by Grossman and Krueger in 1991, which implies a dynamic relationship between different indicators of environmental degradation and per capita income. In general, the curve suggests that a country’s economic growth initially leads to environmental degradation. After per capita income of the country reaches certain stages, the relationship reverses (economic growth leads to progressions of environmental quality). This curve has been a dominant modeling for economists investigating relationship between ambient pollution and social developments, and it seems guarantee future reduction in pollutant-emissions of developing countries. This study will focus on air pollution problems in developing countries and investigate whether the trend described by EKZ Curve holds constant with different environmental and social indicators like HDI, AQI and GDP.

Background In clinical practice, decision about management of choledocholithiasis is driven by availability of resources and expertise, patients and healthcare professional preferences. This survey is aimed to describe the approach of physicians and surgeons for the management of choledocholithiasis.

Method A 36-question online survey was conducted using Google Forms on various aspects of management of choledocholithiasis.

Results The responses from 323 participants were included, of which 202 (62.54%) were physicians and 121 (37.46%) were surgeons. The proportion of responders who do not follow American or European Society of Gastrointestinal Endoscopy guidelines is associated with increasing age and experience of responders (p = 0.0001), while place of work (private vs. teaching) and broad specialty (physician vs surgeon) are not associated (p >0.05). For patients with high likelihood of choledocholithiasis, 123 (38.1%) participants prefer to do endoscopic ultrasound/magnetic resonance cholangiopancreatography (EUS/MRCP) rather than directly performing endoscopic retrograde cholangiopancreatography/intraoperative cholangiography (ERCP/IOC). For intermediate likelihood, MRCP is more commonly preferred compared with EUS, due to local availability (44%), expertise (39.6%), healthcare professionals preference (30.7%), and patients preference (17.3%). For difficult common bile duct (CBD) stones, short biliary sphincterotomy with large balloon sphincteroplasty (59.4%), followed by laparoscopic CBD exploration are commonly used approaches. Prophylactic CBD stent placement after ERCP and CBD clearance is common practice. Preoperative ERCP followed by cholecystectomy is more preferred approach than cholecystectomy and CBD exploration.

Conclusion There is considerable variability in the management of choledocholithiasis. The practices such as use of EUS/MRCP for high likelihood group, use of prophylactic CBD stent placement after ERCP and CBD clearance, and use of single stage approach especially in patient with intermediate likelihood group should be addressed in future studies.

Published: December 2022

Background Burnout syndrome is recognized as a global issue, and as medical practice is stressful, healthcare workers are found to be burnt out and exhausted very soon, which is reflected negatively on the medical staff well-being, patients' outcome, and the overall organizational performance.

Aim This study is planned to assess the magnitude of burnout among physicians in Benghazi-Libya.

Methods This cross-sectional study was carried out in 2020 on a total of 150 physicians working at different departments of internal medicine in Benghazi-Libya. The Maslach Burnout Inventory collection instrument was used to assess the three components of burnout syndrome: emotional exhaustion, depersonalization, and reduced personal accomplishment. High scores in emotional exhaustion and depersonalization and low scores in personal accomplishment are indicative of high burnout. The statistical analyses of the data were performed using the SPSS version 21. The level of statistical significance was considered as p-value less than 0.05.

Results 60% of the respondents were females and 40% were males. About 14.7% had high emotional exhaustion, 92% had high depersonalization, and 87.3% had low personal accomplishment scores. Statistical analysis showed no significant relationship between gender and burnout. Alternatively, a significant association was found between degree certificate and emotional exhaustion, as moderate- and high-level burnout were more prevalent among MBCHB participants than those with masters and board degrees. No association was found between degree certificate and depersonalization or personal accomplishment.

Conclusion Burnout is prevalent among internal medicine doctors in Benghazi, with the newly graduated medical personnel scoring higher rates of burnout than doctors with higher degrees. No relationship was found between gender and burnout.
Nomenclature of Pancreatic Fluid Collections following Acute Pancreatitis: Need to Further Revise the Atlanta Classification System!
Authors: Rana Surinder Singh , Gupta Rajesh
Published: December 2022

A better understanding of the disease pathophysiology, improved imaging modalities, and the development of minimally invasive interventions led to the revision of the Atlanta classification and new terminologies for the pancreatic fluid collections (PFCs) occurring in acute pancreatitis. Peripancreatic necrosis (PPN) or extra-pancreatic necrosis (EPN) has been reported as a distinct morphological entity with a better outcome than combined pancreatic and peripancreatic necrosis as well as pancreatic parenchymal necrosis alone and slightly worse than acute interstitial pancreatitis. In this news and views, we discuss a study that compared the morphological features and outcomes of endoscopic drainage of walled off necrotic collections developing after EPN alone with those developing after PN with or without EPN.
Charcot-Marie-Tooth Disease Type 4C and Autosomal Dominant Heterozygous Ichthyosis Vulgaris, with Bilateral Hearing Loss: A Novel Association with Review of Literature

Published: December 2022

A 3-year-old boy, firstborn to nonconsanguineous parents, presented with motor development delay and floppiness of bilateral lower limbs since birth. No significant family history presented at time of check-up. He could stand with support, eat with a spoon without spillage, and speak in two-word sentences. There was no history suggestive of cranial nerve impairment. Examination revealed normal head circumference, dry, scaly skin lesions on the trunk, distal weakness with sluggish deep tendon reflexes in bilateral lower limbs, and a high stepping gait. Nerve conduction studies revealed demyelinating polyneuropathy. Brain stem-evoked response audiometry testing revealed auditory neuropathy. Clinical exome sequencing revealed a known pathogenic variant of 3325C > T in the SH3TC2 gene suggestive of Charcot-Marie-Tooth disease type 4C and ichthyosis vulgaris with a novel variant of 2218C > T in the FLG gene. We have reviewed the available literature for reported associations of Charcot-Marie-Tooth disease type 4C and ichthyosis vulgaris. This is probably the first reported association of Charcot-Marie-Tooth disease type 4C and ichthyosis vulgaris with bilateral hearing loss.

Published: December 2022

Spondylocarpotarsal synostosis syndrome (SCT) is a very rare skeletal dysplasia characterized by vertebral, carpal, and tarsal fusion; growth retardation; and mild dysmorphic facial features. Variants in FLNB, MYH3, and RFLNA have been implicated in this dysplasia. We report the clinical and radiological follow-up of seven SCT pediatric cases associated with biallelic FLNB variants, from four Argentinian families. The seven cases share previously described facial characteristics: round facies, large eyes, and wide based nose; all of them had variable height deficit, in one case noted early in life. Other findings included clinodactyly, joint limitation without bone fusion, neurosensorial hearing loss, and ophthalmological compromise. All cases presented with spinal fusion with variable severity and location, carpal bones coalition, and also delay in carpal ossification. The heterozygous carrier parents had normal height values to −2.5 score standard deviation, without skeletal defects detected. Three different FLNB variants, one nonsense and two frameshift, were detected, all of which were predicted to result in a truncated protein or are degraded by nonsense mediated decay. All cases had at least one copy of the nonsense variant, c.1128C> G; p. (Tyr376*), suggesting the presence of a common ancestor.

Authors: Nolla-Saltiel R. , Bedford R. B.
Published: December 2022

This review focuses on cross-coupling methodologies that utilize aryl and vinyl electrophiles relying on iron-based catalysts. We have outlined the most relevant and better-established methodologies; leading to the discussion of significant cases based on hard nucleophiles, with the number of examples dropping with their increasing softness. In addition, we describe several useful transformations based on reactive unsaturated nucleophiles, such as acetylenes and alkenes.

Published: December 2022

The availability of potable water is a challenging issue for many Asian countries where economies are still expanding and the population is growing. It is not difficult to observe that water scarcity will become far worse, sooner rather than later. In this study, we investigate the relationships among water indices in five Asian markets (namely China, Hong Kong, Japan, Philippines and Singapore) for the sample period 2005–2018 using the DCC-GARCH model. The empirical results confirm that volatility spillover exists among all the five water indices and there are persistent positive volatility effects. Further, we find that portfolio diversification is possible and benefits may be gained due to the contrasting correlations between pairs of these water indices. The findings of this study may be useful to academics, researchers, policymakers and major water investors worldwide in further comprehending the challenges faced by the Asian water market.
