Transcranial pulsed current stimulation (tPCS) is a promising non-invasive brain stimulation technique that has gained considerable attention in recent years. The purpose of this review is to provide an overview of the existing literature on tPCS, examine the scope and nature of previous research, investigate its underlying mechanisms, and identify gaps in the literature. A search of online databases resulted in 36 published tPCS studies from inception until May 2023. These studies were categorized into three groups: human studies on healthy individuals, patient studies with pathological conditions, and animal studies. The findings suggest that tPCS has the potential to modulate brain excitability by entraining neural oscillations and utilizing stochastic resonance. However, the mechanisms underlying the effects of tPCS are not yet fully understood and require further investigation. Furthermore, the included studies indicate that tPCS may have therapeutic potential for neurological diseases. However, before tPCS can be applied in clinical settings, a better understanding of its mechanisms is crucial. In this regard, the tPCS studies were categorized into four types of research: basic, strategic, applied, and experimental research, to identify the nature of the literature and gaps. Analysis of these categories revealed that tPCS, with its diverse parameters, effects, and mechanisms, presents a wide range of research opportunities for future investigations.

While historically confined to isolated research laboratories, electroencephalography (EEG) paradigms can finally be used in studies involving walking and other complex behaviors. This transition from isolated/immobile to unstructured mobile research can open new doors to understanding attentional processes as they occur naturally. However, there are current limitations in mobile EEG that must be overcome to achieve great quality signals. We examine the feasibility of mobile paradigms, including ecological validity, artifact correction techniques, and methodological considerations. We review several mobile studies related to attentional demands. This includes the replication of robust effects like the P3 in mobile paradigms in our lab, studies using walking, cycling, and dual tasking to study attention. We discuss how the mobile approach compliments traditional laboratory paradigms while it can add new dimensions to cognitive and attentional research. We discuss promising applications of portable EEG in workplace safety and other areas including road safety, rehabilitation medicine, and brain-computer interfaces.

HPV infection can lead to HPV-related cancer in men, including the anus, penile, and oropharyngeal cancers and precancerous lesions. This study retrospectively investigated HPV prevalence and genotype distribution in Liaocheng men between 2016 and 2022. The total HPV positive rate was 64.87% (2388/3681, 95% CI: 63.32%-66.40%), where HR-HPV and LR-HPV accounted for 42.49% (1564/3681, 95% CI: 40.90%-44.09%) and 69.71% (2566/3681, 95% CI: 68.20%-71.17%), respectively. The mixed HPV infection rate of two and more genotypes was 35.72%. The infection rate of HR-HPV increased with the number of positive cases annually from 2016 (16.91%) to 2022 (46.59%). The most common HR-HPV genotypes were HPV16 (11.60%), HPV52 (6.95%), and HPV59 (6.28%), whereas the least common HR-HPV was HPV26. The most common LR-HPV genotypes were HPV6 (56.99%), HPV11 (23.79%), and HPV43(6.37%). The 9v HPV vaccine preventable for LR-HPV and HR-HPV accounted for 80.78% and 30.40%, respectively, in this study. Most HPV-positive patients aged 1-86 were in the 30-39 age group. This study confirmed that HPV prevalence in Liaocheng men was common and diverse. HPV16, HPV52, and HPV59 are widely distributed in Liaocheng men, and the male HR-HPV infection rate remained high in this region. Regarding public health and cancer prevention, it is recommended and effective to include the HPV vaccination in the national vaccination program for men.

Beginning in the early 2010s, an increased incidence of interstitial lung disease in systemic juvenile idiopathic arthritis (sJIA-LD) in pediatric patients has been identified. Despite the increase in prevalence of sJIA-LD, little is known about this disease process and effective therapeutic management. In this single-center, retrospective case series of 9 patients, we analyze demographic, clinical, radiographic, and laboratory data to corroborate common clinical characteristics and describe an approach for diagnosis and monitoring of interstitial lung disease in children with sJIA. Our results were similar to other described cases of sJIA-LD as patients in our cohort were more likely to be younger, have a history of macrophage activation syndrome and prior use of biologic therapies. In contrast to prior studies, they did not present with lymphadenopathy and hepatosplenomegaly. We discuss our management of this rare disease process. More research is necessary to understand the increased incidence and treatment of sJIA-LD in pediatric population.

Title: Acute Myeloid Leukemia with Unreported Translocation (x; 3) (q24; p13): A case report

Cold stress restricts plant development seriously, resulting in heavy agricultural losses. We found a critical transcription factor network in Medicago ruthenica is involved in plant adaptation to low temperature. APETALA2/ETHYLENE RESPONSIVE FACTOR (AP2/ERF) transcription factor MrERF039 was transcriptionally induced by cold stresses in M. ruthenica. We established an agrobacterium-mediated transient expression system and found that MrERF039 plays an active role in the cold response of M. ruthenica. Overexpression of MrERF039 significantly increased the soluble sugar content, which was eventually expressed as the accumulation of glucose and maltose. Electrophoretic mobility shift assays (EMSA) and yeast monohybrid crosses showed that MrERF039 could bind to the DRE cis-acting element on the MrCAS15A promoter. Additionally, the methyl group of the 14th amino acid in the MrERF039 protein was required for the binding. Transcriptome results analysis showed that the MrERF039 gene acted as a sugar molecular switch, regulating many sugar transporters and sugar metabolism related genes. In addition, we found that MrERF039 can directly regulate the expression of β-amylase gene, UDP glycosyltransferase gene and C2H2 zinc finger protein gene. And the significant increase in glucose and maltose content may be caused by the breakdown of starch degraded by β-amylase. In conclusion, these findings suggest that high expression of the MrERF039 gene can significantly improve the cold tolerance of M. ruthenica root tissues during cold acclimation. These provides a new theoretical basis and candidate genes for breeding new legume forage varieties with high resistance, high yield and high protein.

INTRODUCTIONOver-the-counter (OTC) drugs have sometimes been used for suicide attempt and it was reported that among OTC drugs used in adults the most common was acetaminophen in emergency hospitals in Canada [1]. Other OTC analgesics in their cases included acetylsalicylates, ibuprofen and others, and deaths were observed in case of acetaminophen and acetylsalicylate intoxications [1]. Respiratory insufficiency could occur in acetylsalicylate intoxications by way of central nervous system involvements, metabolic disorders or vomiting-induced suffocation [1]. Severe respiratory insufficiency will cause miscellaneous neurological manifestations because of secondary hypoxic-ischemic encephalopathy (HIE). In these cases the cerebellum is one of the vulnerable sites [2, 3]. However, exclusive severe cerebellar atrophy associated with remarkable cerebellar symptoms after respiratory insufficiency has not been reported probably because patients with HIE usually show extensive brain lesions as a whole.We experienced a patient who exhibited exclusively marked cerebellar dysfunction and atrophy on magnetic resonance imaging three years after salicylate poisoning and respiratory insufficiency. Cerebellar atrophy was considered to be induced in these unique clinical situations, although its definite pathophysiology remained unknown.

1. Fine root distribution influences the potential for resource acquisition in soil profiles, which defines how plants interact with local soil environments; however, a deep understanding of how fine root vertical distribution varies with soil structural variations and across plant ages is lacking. 2. We subjected four xerophytic species native to an arid valley of China, Artemisia vestita, Bauhinia brachycarpa, Sophora davidii, and Cotinus szechuanensis, to increasing rock fragment content (RFC) treatments (0%, 25%, 50%, and 75%, v v-1) in an arid environment and measured fine root vertical profiles over four years of growth. 3. Fine root depth and biomass of woody species increased with increasing RFC, but the extent of increase declined with plant age. Increasing RFC also increased the degree of interannual decreases in fine root diameter. The limited supply of soil resources in coarse soils explained the increases in rooting depth and variations in the pattern of fine root profiles across RFC. Fine root depth and biomass of the subshrub species (A. vestita) in soil profiles decreased with the increase in RFC and plant age, showing an opposite pattern from the other three woody species. 4. Within species, the annual increase in fine root biomass varied with RFC, which led to large interannual differences in the patterns of fine root profiles. Capacity of younger or subshrub plants to cope with soil environmental changes were greater than the older or shrub plants. These results provide insights into the limitations of soil resources in dry and rocky environments, and have management implications for degraded agroforest ecosystem.

Single-cell transcriptomics analysis is an advanced technology that can describe the intracellular transcriptome in complex tissues. It profiles and analyses datasets by single-cell RNA sequencing. Neurodegenerative diseases are identified by the abnormal apoptosis of neurons in the brain with few or no effective therapy strategies at present, which has been a growing healthcare concern and brought a great burden to society. The transcriptome of individual cells provides deep insights into previously unforeseen cellular heterogeneity and gene expression differences in neurodegenerative disorders. It detects multiple cell subsets and functional changes during pathological progression, which deepens the understanding of the molecular underpinnings and cellular basis of neurodegenerative diseases. Furthermore, the transcriptome analysis of immune cells shows the regulation of immune response. Different subtypes of immune cells and their interaction are found to contribute to disease progression. This finding enables the discovery of novel targets and biomarkers for early diagnosis. In this review, we emphasize the principles of the technology, and its recent progress in the study of cellular heterogeneity and immune mechanisms in neurodegenerative diseases. The application of single-cell transcriptomics analysis in neurodegenerative disorders would help explore the pathogenesis of these diseases and develop novel therapeutic methods.

Social buffering is the phenomenon in which the presence of an affiliative conspecific mitigates stress responses. We previously demonstrated that social buffering completely ameliorates conditioned fear responses in rats. The present study explored the neurochemical background of this social buffering. In Experiment 1, fear-conditioned subjects first received an intraperitoneal injection of either naloxone (non-selective opioid receptor antagonist), haloperidol (dopamine D2 receptor antagonist), SR49059 (vasopressin V1A receptor antagonist), atosiban (oxytocin receptor antagonist), or saline. The subjects were then exposed to a conditioned stimulus with an unfamiliar non-conditioned rat. Naloxone, but not the other three antagonists, blocked social buffering. In Experiment 2, we assessed the effect of naloxone on locomotor activity during an open-field test. Naloxone did not affect walking steps during the test. Therefore, it is unlikely that the results of Experiment 1 were due to decreased activity by naloxone. In Experiment 3, we assessed Fos expression in 16 brain regions accompanied by the blockade of social buffering by naloxone. Consistent with the results of Experiment 1, Fos expression was increased in the paraventricular nucleus of the hypothalamus. In addition, Fos expression was decreased in the nucleus accumbens shell, anterior cingulate cortex, and insular cortex and tended to be decreased in the nucleus accumbens core. Naloxone thus appears to affect these four regions and/or act upstream of these regions during blockade of social buffering. Based on these results, we conclude that naloxone blocks social buffering of conditioned fear responses in rats.

Enzymes that catalyze post-translational modifications of peptides and proteins (PTM-enzymes) – proteases, protein ligases, oxidoreductases, kinases, and other transferases - are foundational to our understanding of health and disease and empower applications in chemical biology, synthetic biology, and biomedicine. To fully harness the potential of PTM-enzymes, there is a critical need to decipher their enzymatic and biological mechanisms, develop molecules that can probe and reprogram them, and endow them with improved and novel functions. These objectives are contingent upon implementation of high-throughput functional screens and selections that interrogate large sequence libraries to isolate desired PTM-enzyme properties. This review discusses the principles of S. cerevisiae organelle sequestration to study and engineer PTM-enzymes. These include methods that modify yeast surface display and employ enzyme-mediated transcription activation to evolve the activity and substrate specificity of proteases and protein ligases. We also present a detailed discussion of yeast endoplasmic reticulum (ER) sequestration for the first time. Where appropriate, we highlight the major features and limitations of different systems, specifically how they can measure and control enzyme catalytic efficiencies. Taken together, yeast-based high-throughput sequestration approaches significantly lower the barrier to understanding how PTM-enzymes function and how to reprogram them.

In this research, we explore whether a dendrogeomorphological assessment of tree scarring can accurately summarize past ice-jam flooding events occurring at a given reach of a river. A sample site was chosen with a history of ice-jam flooding located in close proximity to a river gauge station. Samples were collected along a 200-metre stretch of riverbank to capture the variation in elevations and possible different ice-jam flooding events. Disk samples were collected from trees with visual scarring evidence that indicated they had endured a past ice-jam event. Tree cores from an adjacent stand were collected to create a master chronology for each of the sampled species. Tree disks and cores were analyzed under a microscope using a Velmex stage system, then visually and statistically crossdated using the program COFECHA. Based on the last year of tree growth, years of individual injury events were established. The years of injury event dates were compared against the years of highest instantaneous maximum water elevations from gauged river data. The two data sets correlated, as years with highest recorded injury event dates were also the years of highest instantaneous water level elevations. The most common years of injury event dates were directly reflected in the top five years of highest river instantaneous water level elevations. In addition, the year of 2020 had the highest water elevations in the past 27 years, which was again reflected in the dendrogeomorphological data as the injury event year of 2020 was recorded on over 90% of the sampled tree disks. The correlation found between the gauged river data and the dendrogeomorphological data strongly suggests that past ice-jam flooding event dates can accurately be determined through the analysis of trees in riverbank stretches that have been impacted by ice-jams. The relationship of the gauged river data to the dendrogeomorphological data will therefore allow researchers to determine ice-jam site histories in remote areas where no gauged data exists. The site histories can provide information such as the years or heights that past ice-jam flooding occurred, which could then be used in ice-jam flooding hazard assessments.

Many software development methodologies introduced to date place users at the centre of development process. Although the user is an important asset in the software development cycle however the user-centred approach is not sufficient to develop a software product that is structurally robust and reliable. User involvement in the development process does not always guarantee resilience and a more efficient design. To address this a hybrid-based software development paradigm is proposed here where the software development cycle includes a grammar model-based compiler with user-centred approach. The efficacy of the proposed system is tested with the development of an innovative computer-aided drawing technology (SETUP09) for blind and visually impaired people and the results are compared with an existing non-hybrid-based drawing software (IC2D). The results of this study confirm SETUP09 improves user satisfaction and provides abstract and concrete level system flexibility. Provided here are guidelines of the proposed hybrid approach for software development based on a formal approach. This hybrid approach enables the software designer to evaluate the software semantics before user scrutinization. The benefits of the approach include the facilitation of alternate development pathways affording the software designer the flexibility to amend the software without incurring significant technical challenges. In fact, the proposed approach enables the creation of a structural design that is independent from the development pathways. This approach should ease the time constraint in product development and resource constraints.

Background: In emergency departments, rapid screening of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is important for arranging limited isolation resources and patient care during the coronavirus disease 2019 (COVID-19) pandemic. STANDARD M10 SARS-CoV-2 (SD Biosensor) is a recently developed cartridge-based RT-PCR that provides a turnaround time of 1 h, which is shorter than that for conventional RT-PCR. This study evaluated the clinical performance of STANDARD M10 in an emergency department. Methods: From March to June 2022, two pairs of nasopharyngeal and oropharyngeal swabs were collected from patients visiting an emergency department. Respective specimens underwent rapid RT-PCR using STANDARD M10 and conventional RT-PCR using Allplex SARS-CoV-2 (Seegene). When discordant results occurred, specimens undergoing the STANDARD M10 were retested with the Allplex to exclude specimen variations. Retest results replaced initial results of the Allplex. Clinical performance of STANDARD M10 was compared with Allplex. Results: The study enrolled 1,971 patients. COVID-19 prevalence was 6.2% based on the Allplex. Compared with the Allplex, overall agreement, positive percent agreement, and negative percent agreement of STANDARD M10 were 99.5% (95% CI: 99.1–99.8%), 95.9% (95% CI: 90.8–98.3%), and 99.8% (95% CI: 99.4–99.9%), respectively. Discordant results between STANDARD M10 and Allplex were observed only in specimens with Ct >33 using the Allplex. Conclusions: The STANDARD M10 showed reliable diagnostic performance for detecting SARS-CoV-2 in emergency departments and is a useful tool in emergency healthcare systems because of its easy-to-use cartridge-based assay and short resulting time for detecting SARS-CoV-2.

This article analyzes the visual, auditory, vocal, and motor advantages among autistic people with speech onset delay (A-SOD) compared with autistic people without speech delay (A-NoSOD) and sometimes non-autistic people. Importantly, their intelligence and communication skills are often underestimated. In addition, this paper provides suggestions to leverage strengths and address weaknesses from a sensory-motor perspective. Visual strengths are applied to IQ testing, reading and writing, and interpreting facial expressions. Auditory applications range from pain to music to speech development. Implications include suggestions for both production and perception of speech. The recommendations address both language’s relationship to motor development and the role of general language learning. Paradoxically, strengths in auditory perception may contribute to speech delay but also help A-SOD catch up to A-NoSOD, and continue to help A-SOD develop. Understanding A-SOD’s strengths may help to recognize how they make developmental gains in speech and language, and build from their strengths.

The pervasiveness of racism in the U.S. and its negative impact on key development outcomes has led researchers to uncover mediators, of which this article argues efficacy should be considered. Self-efficacy, one’s belief in their capability to accomplish a task or goal, can be measured in multiple domains of functioning and contexts to predict behavior. The current study examines possible specificity in the relation between discrimination (general discrimination [GD] and school discrimination [SD]) and efficacy (academic efficacy [AE] and efficacy to combat discrimination [ECD]), whether resilience modifies these associations, and if these processes differ by gender. 879 Black youth (47% female; mean age = 12, SD = 0.58) were included in the analyses. Findings suggest that school discrimination experiences perceived resilience impact domains of efficacy differently. Resilience positively impacted AE, but no significant moderation effects were found.
