Abstract Understanding neuroectoderm formation and subsequent diversification to functional neural subtypes remains elusive. We show here that human embryonic stem cells (hESCs) differentiate primitive after 8–10 days. At this stage, uniformly exhibit columnar morphology express markers, including anterior but not posterior homeodomain proteins. The identity of these develops regardless morphogens present during initial specification. This phenotype can be maintained or transformed a caudal...
The directed differentiation of forebrain neuronal types from human embryonic stem cells (hESCs) has not been achieved. Here, we show that hESCs differentiate to telencephalic progenitors with a predominantly dorsal identity in chemically defined medium without known morphogens. This is attributed endogenous Wnt signaling, which upregulates the truncated form GLI3, repressor sonic hedgehog (SHH). A high concentration SHH, or inhibition by dickkopf 1 (DKK1) together low almost completely...
Coronovirus disease 2019 (COVID-19) has spread rapidly across the globe. People of all ages are susceptible to COVID-19. However, literature reports on pediatric patients limited. To improve recognition COVID-19 infection in children, we retrospectively reviewed two confirmed cases from family clusters. Both clinical features and laboratory examination results children their members were described. The only presented with mild respiratory or gastrointestinal symptoms. them had normal chest...
Aiming to address the shortcomings of traditional blockchain technologies, characterized by high storage redundancy and low transaction query efficiency, we propose a lightweight sender-based architecture (LSB). In this architecture, linkage between blocks is associated with user initiating transaction, hash newly generated block recorded in user’s wallet, thereby facilitating retrieval. Each node must store only that pertain it, significantly reducing costs. To ensure normal operation...
Specification of distinct cell types from human embryonic stem cells (hESCs) is key to the potential application these naïve pluripotent in regenerative medicine. Determination nontarget differentiated populations, which lacking field, also crucial. Here, we show an efficient differentiation motor neurons ( approximately 50%) by a simple sequential retinoid acid and sonic hedgehog (SHH) chemically defined suspension culture. We discovered that purmorphamine, small molecule activates SHH...
Human embryonic stem cells (hESCs) offer a platform to bridge what we have learned from animal studies human biology. Using oligodendrocyte differentiation as model system, show that sonic hedgehog (SHH)-dependent sequential activation of the transcription factors OLIG2, NKX2.2 and SOX10 is required for specification ventral spinal OLIG2-expressing progenitors, pre-oligodendrocyte precursor (pre-OPCs) OPCs hESC-derived neuroepithelia, indicating conserved transcriptional network underlies...
Human neuronal models of hereditary spastic paraplegias (HSP) that recapitulate disease-specific axonal pathology hold the key to understanding why certain axons degenerate in patients and developing therapies. SPG4, most common form HSP, is caused by autosomal dominant mutations SPAST gene, which encodes microtubule-severing ATPase spastin. Here, we have generated a human model SPG4 establishing induced pluripotent stem cells (iPSCs) from an patient differentiating these into telencephalic...
How to achieve reliable routing has always been a major issue in the design of communication networks, among which mobile ad hoc networks (MANETs) possess most adversarial networking environment due absence fixed infrastructure, nature open transmission media and dynamic network topology. These characteristics also make protocols MANETs become even more challenging. In this paper, we propose an evolutionary self-cooperative trust (ESCT) scheme that imitates human cognitive process relies on...

This research article proposes a compact frequency and pattern reconfigurable flexible antenna for heterogeneous applications. A triangular monopole with semicircular stub is made tunable by connecting disconnecting two inverted L-shaped stubs utilizing diodes. When either of the connected to radiator, relative phase difference happens at both ends radiator that changes direction electromagnetic radiations, consequently reconfigurability can be obtain. Besides that, because reactive load...
Deepfakes are notorious for their unethical and malicious applications to achieve economic, political, social reputation goals. Recent years have seen widespread facial forgery, which does not require technical skills. Since the development of generative adversarial networks (GANs) diffusion models (DMs), deepfake generation has been moving toward better quality. Therefore, it is necessary find an effective method detect fake media. This contemporary survey provides a comprehensive overview...

Localization in Wireless Sensor Networks (WSNs) has been an active topic for more than two decades. A variety of algorithms were proposed to improve the localization accuracy. However, they are either limited two-dimensional (2D) space, or require specific sensor deployment proper operations. In this paper, we a three-dimensional (3D) scheme WSNs based on well-known parametric Loop division (PLD) algorithm. The localizes node region bounded by network anchor nodes. By iteratively shrinking...
Investigating and classifying sentiments of social media users (e.g., positive, negative) towards an item, situation, system are very popular among researchers. However, they rarely discuss the underlying socioeconomic factor associations for such sentiments. This study attempts to explore factors associated with positive negative people about reopening economy, in United States (US) amidst COVID-19 global crisis. It takes into consideration situational uncertainties (i.e., changes work...

Many designed 0.5 ¿m 65 nm processes have been reported. Table 4 summarizes these switches. Some them become great candidates WLAN UWB radios. However, none met the requirements mobile cellular WPAN 60-GHz device innovations novel ideas such as artificial dielectric strips bandgap structures may provide a comprehensive solution to challenges
Hereditary spastic paraplegias are a large, diverse group of neurological disorders (SPG1-71) with the unifying feature prominent lower extremity spasticity, owing to length-dependent axonopathy corticospinal motor neurons. The most common early-onset form pure, autosomal dominant hereditary paraplegia is caused by mutation in ATL1 gene encoding atlastin-1 GTPase, which mediates homotypic fusion ER tubules polygonal network. We have identified p.Pro342Ser young girl pure SPG3A. This residue...
Abstract Spinal muscular atrophy (SMA) presents severe muscle weakness with limited motor neuron (MN) loss at an early stage, suggesting potential functional alterations in MNs that contribute to SMA symptom presentation. Using induced pluripotent stem cells (iPSCs), we found displayed hyperexcitability increased membrane input resistance, hyperpolarized threshold and larger action amplitude, which was mimicked by knocking down full length survival (SMN) non-SMA MNs. We further discovered...
