Tripod transcranial alternating current stimulation at 5-Hz to alleviate anxiety symptoms: a preliminary report

Introduction: One of the most common applications of transcranial electrical stimulation (tES) at low current intensity is to induce a relaxed state or reduce anxiety. With technical advancement, different waveforms, montages, and parameters can be incorporated into the treatment regimen. We developed a novel protocol to treat individuals with anxiety disorders by transcranial alternating current stimulation (tACS). Methods: A total of 27 individuals with anxiety disorders underwent tACS treatment for 12 sessions, with each session lasting 25 minutes. tACS at 5 Hz was applied to F4 (1.0 mA), P4 (1.0 mA), and T8 (2.0 mA) EEG lead positions (tripod), with sinewave oscillation between T8 and F4/P4. We evaluated the primary and secondary outcomes using the Beck Anxiety Inventory (BAI) and neuropsychological assessments. Results: Of the 27 patients, 19 (70.4%) experienced a reduction in symptom severity greater than 50%, with an average reduction of BAI 58.5%. All reported side effects were mild, with itching or tingling being the most common complaint. No significant differences were noted in attention, linguistic working memory, visuospatial working memory, or long-term memory in neuropsychological assessments. Conclusion: The results suggest the potential of this novel tripod tACS design as a rapid anxiety alleviator and the importance of a clinical trial to verify its efficacy.
Neurological disorders after severe pneumonia are associated with translocation of endogenous bacteria from the lung to the brain

Neurological disorders are a common feature in patients who recover from severe acute pneumonia. However, the underlying mechanisms remain poorly understood. Here, we show that the neurological syndromes after severe acute pneumonia are partly attributed to the translocation of endogenous bacteria from the lung to the brain during pneumonia. Using principal components analysis, similarities were found between the brain’s flora species and those of the lungs, indicating that the bacteria detected in the brain may originate from the lungs. We also observed impairment of both the lung-blood and brain-blood barriers, allowing endogenous lung bacteria to invade the brain during pneumonia. An elevated microglia and astrocyte activation signature via bacterial infection–related pathways was observed, indicating a bacterial-induced disruption of brain homeostasis. Collectively, we identify endogenous lung bacteria that play a role in altering brain homeostasis, which provides insight into the mechanism of neurological syndromes after severe pneumonia.
Effects of Single-nucleotide Polymorphisms on microRNA-Based Gene Regulation and Their Association With Disease

Alternative polyadenylation (APA) can for example occur when a protein-coding gene has several polyadenylation (polyA) signals in its last exon, resulting in messenger RNAs (mRNAs) with different 3' untranslated region (UTR) lengths. Different 3'UTR lengths can give different microRNA (miRNA) regulation such that shortened transcripts have increased expression. The APA process is part of human cells' natural regulatory processes, but APA also seems to play an important role in many human diseases. Although altered APA in disease can have many causes, we reasoned that mutations in DNA elements that are important for the polyA process, such as the polyA signal and the downstream GU-rich region, can be one important mechanism. To test this hypothesis, we identified single nucleotide polymorphisms (SNPs) that can create or disrupt APA signals (APA-SNPs). By using a data-integrative approach, we show that APA-SNPs can affect 3'UTR length, miRNA regulation, and mRNA expression--both between homozygote individuals and within heterozygote individuals. Furthermore, we show that a significant fraction of the alleles that cause APA are strongly and positively linked with alleles found by genome-wide studies to be associated with disease. Our results confirm that APA-SNPs can give altered gene regulation and that APA alleles that give shortened transcripts and increased gene expression can be important hereditary causes for disease.
FADE OUT HIV: An Educational Intervention Allying Black Community Barbers, Their Clients, and Community Clinicians

ABSTRACT Black individuals in the United States are less likely to use medication to prevent HIV (pre-exposure prophylaxis, or PrEP) than White individuals and are significantly more likely to receive a new HIV diagnosis. Because of America’s long history of unethical medical and research practices and ongoing prejudice and bias, Black Americans have mistrust towards the medical community. This distrust, along with the social determinants of health, leads to low participation in health care. Health interventions at culturally “safe” and familiar venues are a popular strategy to engage Black Americans in health care. In the United States, barbershops are staples of the Black community and the utility of barbershops as a venue for delivering interventions has been successfully explored. We describe FADE OUT HIV, a program designed to increase barberknowledge of prevalence of HIV in the Black community; facilitatediscussions between Black barbers and their Black clients about HIVexposure, prevention, and treatment; provide free HIV tests forbarbers’ clients; and educate community clinicians via live andenduring webcasts about HIV prevention and treatment. Clinician education was designed to facilitate HIV screening and ensure that the barber clients would be referred to clinicians who were knowledgeable about HIV. The learning objectives of the education were focused on barriers that prevent HIV screening and PrEP uptake and strategies to overcome these barriers, monitoring recommendations for people using PrEP, the benefits and limitations of new and in-development PrEP, and the importance of rapid initiation of antiretroviral therapy (ART). As a result of this programme, 308 HIV tests were administered to barber clients at hosted events in Los Angeles and clinician knowledge and competence increased by 33% and 34%, respectively.
P-MSC-derived extracellular vesicles facilitate diabetic wound healing via miR-145-5p/ CDKN1A-mediated functional improvements of high glucose-induced senescent fibroblasts

Abstract Background Persistent hyperglycaemia in diabetes causes functional abnormalities of human dermal fibroblasts (HDFs), partially leading to delayed skin wound healing. Extracellular vesicles (EVs) containing multiple pro-healing microRNAs (miRNAs) have been shown to exert therapeutic effects on diabetic wound healing. The present study aimed to observe the effects of EVs derived from placental mesenchymal stem cells (P-MSC-EVs) on diabetic wound healing and high glucose (HG)-induced senescent fibroblasts and to explore the underlying mechanisms. Methods P-MSC-EVs were isolated by differential ultracentrifugation and locally injected into the full-thickness skin wounds of diabetic mice, to observe the beneficial effects on wound healing in vivo by measuring wound closure rates and histological analysis. Next, a series of assays were conducted to evaluate the effects of low (2.28 x 1010 particles/ml) and high (4.56 x 1010 particles/ml) concentrations of P-MSC-EVs on the senescence, proliferation, migration, and apoptosis of HG-induced senescent HDFs in vitro. Then, miRNA microarrays and real-time quantitative PCR (RT–qPCR) were carried out to detect the differentially expressed miRNAs in HDFs after EVs treatment. Specific RNA inhibitors, miRNA mimics, and small interfering RNA (siRNA) were used to evaluate the role of a candidate miRNA and its target genes in P-MSC-EV-induced improvements in the function of HG-induced senescent HDFs. Results Local injection of P-MSC-EVs into diabetic wounds accelerated wound closure and reduced scar widths, with better-organized collagen deposition and decreased p16INK4a expression. In vitro, P-MSC-EVs enhanced the antisenescence, proliferation, migration, and antiapoptotic abilities of HG-induced senescent fibroblasts in a dose-dependent manner. MiR-145-5p was found to be highly enriched in P-MSC-EVs. MiR-145-5p inhibitors effectively attenuated the P-MSC-EV-induced functional improvements of senescent fibroblasts. MiR-145-5p mimics simulated the effects of P-MSC-EVs on functional improvements of fibroblasts by suppressing the expression of cyclin-dependent kinase inhibitor 1A and activating the extracellular signal regulated kinase (Erk)/protein kinase B (Akt) signaling pathway. Furthermore, local application of miR-145-5p agomir mimicked the effects of P-MSC-EVs on wound healing. Conclusions These results suggest that P-MSC-EVs accelerate diabetic wound healing by improving the function of senescent fibroblasts through the transfer of miR-145-5p, which targets cyclin-dependent kinase inhibitor 1A to activate the Erk/Akt signaling pathway. P-MSC-EVs are promising therapeutic candidates for diabetic wound treatment.
Synthesis of multifunctional amorphous metallic shell on crystalline metallic nanoparticles

Colloidal nanoparticles can be coated with a conformal shell to form multifunctional nanoparticles. For instance, plasmonic, magnetic, and catalytic properties, chemical stability and biocompatibility can be mixed and matched. Here, a facile synthesis for depositing metal boride amorphous coatings on colloidal metallic nanocrystals is introduced. The synthesis is independent of core size, shape, and composition. We have found that the shell synthesis is limited to nanoparticles capped with short molecular weight and low binding energy ligands, and does not work with polyvinylpyrrolidone (PVP)-coated Ag nanoparticles or thiol-coated Au nanoparticles. Shell thickness can be as thin as 3 nm with no apparent pinholes. High pressure studies show that the coatings are highly resistant to crystallization and are strongly bonded to the crystalline core. By choosing either CoB or NiB for the coating, the composite nanoparticles can be either ferromagnetic or paramagnetic at room temperature, respectively.
Demystification and feasibility of CRISPR technology and gene editing in African laboratories

ABSTRACT Clustered regularly interspaced short palindromic repeats, or CRISPR, is a powerful molecular biology tool that is enabling high-quality genetic research and engineering. However, for practical reasons, but more specifically because of the lack of training and the rapid development of gene-editing technology, the technique is still not well established in African laboratories. For this reason, a consortium formed by the Institut Pasteur of Tunis and Learn and Win decided to organise an international conference and workshop on CRISPR technology in particular and gene editing in general, focusing on the low-budget model more appropriate to the African context. From 12 to 17 June 2023, more than 200 interdisciplinary researchers and students from the life sciences and more than 20 international speakers and trainers gathered at the Institut Pasteur in Tunis, Tunisia, for the First African Conference and Workshop on CRISPR to discuss the latest gene editing technologies and discoveries. This Meeting Review describes the scientific event and highlights the main outcomes of both the conferences and the practical sessions. The symposium was a real success and thrives to educate, train and network international and young scientists in the field of gene editing and gene engineering.
APPLICATION OF TIME-DOMAIN FEATURES WITH NEURAL NETWORK FOR BEARING FAULT DETECTION

The normal functioning of induction motors depend largely on ball bearing. Proper functioning and operation of ball bearing is the result of its maintenance by condition monitoring. Out of the various measures of condition monitoring vibration monitoring is the most extensively used and economical technique to detect, identify and distinguish fault in induction motors. In this research paper induction motor faults have been detected using time domain features of vibration signal. For the automated diagnosis of faults neural network has been designed using values of nine statistical features as input parameters which are: peak value, root mean square value, crest factor, kurtosis, skewness, clearance factor, impulse factor, shape factor and standard deviation. The artificial neural network designed was applied for three conditions of bearing i.e. for healthy bearing, bearing with inner raceway defect and bearing with outer raceway defect. The experimental observation shows that the proposed method is effective and is able to detect the faulty condition with high accuracy.
Tecovirimat Resistance in Mpox Patients, United States, 2022–2023

During the 2022 multinational outbreak of monkeypox virus (MPXV) infection, the antiviral drug tecovirimat (TPOXX; SIGA Technologies, Inc., https://www.siga.com) was deployed in the United States on a large scale for the first time. The MPXV F13L gene homologue encodes the target of tecovirimat, and single amino acid changes in F13 are known to cause resistance to tecovirimat. Genomic sequencing identified 11 mutations previously reported to cause resistance, along with 13 novel mutations. Resistant phenotype was determined using a viral cytopathic effect assay. We tested 124 isolates from 68 patients; 96 isolates from 46 patients were found to have a resistant phenotype. Most resistant isolates were associated with severely immunocompromised mpox patients on multiple courses of tecovirimat treatment, whereas most isolates identified by routine surveillance of patients not treated with tecovirimat remained sensitive. The frequency of resistant viruses remains relatively low (<1%) compared with the total number of patients treated with tecovirimat.
RISING STARS: Mechanistic insights into maternal–fetal cross talk and islet beta-cell development

The metabolic health trajectory of an individual is shaped as early as prepregnancy, during pregnancy, and lactation period. Both maternal nutrition and metabolic health status are critical factors in the programming of offspring toward an increased propensity to developing type 2 diabetes in adulthood. Pancreatic beta-cells, part of the endocrine islets, which are nutrient-sensitive tissues important for glucose metabolism, are primed early in life (the first 1000 days in humans) with limited plasticity later in life. This suggests the high importance of the developmental window of programming in utero and early in life. This review will focus on how changes to the maternal milieu increase offspring’s susceptibility to diabetes through changes in pancreatic beta-cell mass and function and discuss potential mechanisms by which placental-driven nutrient availability, hormones, exosomes, and immune alterations that may impact beta-cell development in utero, thereby affecting susceptibility to type 2 diabetes in adulthood.
ART2Dose: A comprehensive dose verification platform for online adaptive radiotherapy.

BACKGROUND Online adaptive radiotherapy (ART) involves the development of adaptable treatment plans that consider patient anatomical data obtained right prior to treatment administration, facilitated by cone-beam computed tomography guided adaptive radiotherapy (CTgART) and magnetic resonance image-guided adaptive radiotherapy (MRgART). To ensure accuracy of these adaptive plans, it is crucial to conduct calculation-based checks and independent verification of volumetric dose distribution, as measurement-based checks are not practical within online workflows. However, the absence of comprehensive, efficient, and highly integrated commercial software for secondary dose verification can impede the time-sensitive nature of online ART procedures. PURPOSE The main aim of this study is to introduce an efficient online quality assurance (QA) platform for online ART, and subsequently evaluate it on Ethos and Unity treatment delivery systems in our clinic. METHODS To enhance efficiency and ensure compliance with safety standards in online ART, ART2Dose, a secondary dose verification software, has been developed and integrated into our online QA workflow. This implementation spans all online ART treatments at our institution. The ART2Dose infrastructure comprises four key components: an SQLite database, a dose calculation server, a report generator, and a web portal. Through this infrastructure, file transfer, dose calculation, report generation, and report approval/archival are seamlessly managed, minimizing the need for user input when exporting RT DICOM files and approving the generated QA report. ART2Dose was compared with Mobius3D in pre-clinical evaluations on secondary dose verification for 40 adaptive plans. Additionally, a retrospective investigation was conducted utilizing 1302 CTgART fractions from ten treatment sites and 1278 MRgART fractions from seven treatment sites to evaluate the practical accuracy and efficiency of ART2Dose in routine clinical use. RESULTS With dedicated infrastructure and an integrated workflow, ART2Dose achieved gamma passing rates that were comparable to or higher than those of Mobius3D. Additionally, it significantly reduced the time required to complete pre-treatment checks by 3-4 min for each plan. In the retrospective analysis of clinical CTgART and MRgART fractions, ART2Dose demonstrated average gamma passing rates of 99.61 ± 0.83% and 97.75 ± 2.54%, respectively, using the 3%/2 mm criteria for region greater than 10% of prescription dose. The average calculation times for CTgART and MRgART were approximately 1 and 2 min, respectively. CONCLUSION Overall, the streamlined implementation of ART2Dose notably enhances the online ART workflow, offering reliable and efficient online QA while reducing time pressure in the clinic and minimizing labor-intensive work.
Earthquake Geotechnical Engineering Aspects: the 2012 Emilia-Romagna Earthquake (Italy).

On May 20, 2012 an earthquake of magnitude ML=5.9 struck the Emilia Romagna Region of Italy and a little portion of Lombardia Region. Successive earthquakes occurred on May 29, 2012 with ML=5.8 and ML=5.3. The earthquakes caused 27 deaths, of which 13 on industrial buildings. The damage was considerable. 12,000 buildings were severely damaged; big damages occurred also to monuments and cultural heritage of Italy, causing the collapse of 147 campaniles. The damage is estimated in about 5-6 billions of euro. To the damage caused to people and buildings, must be summed the indirect damage due to loss of industrial production and to the impossibility to operate for several months. The indirect damage could be bigger than the direct damage caused by the earthquake. The resilience of the damaged cities to the damage to the industrial buildings and the lifelines was good enough, because some industries built a smart campus to start again to operate in less of one month and structural and geotechnical guidelines were edited to start with the recovering the damage industrial buildings. In the paper a damage survey is presented and linked with the ground effects. Among these, soil amplification and liquefaction phenomena are analyzed, basing on the soil properties evaluation by field and laboratory tests. Particular emphasis is devoted to the damaged suffered by the industrial buildings and to the aspects of the remedial work linked with the shallow foundation inadequacy and to the liquefaction mitigation effects.
Rev–Rev Response Element Activity Selection Bias at the Human Immunodeficiency Virus Transmission Bottleneck

Abstract Background Sexual transmission of human immunodeficiency virus (HIV) is inefficient and results in selection of viral variants based on incompletely understood factors. Functional variation in the Rev–Rev response element (RRE) regulatory axis of HIV affect replication kinetics and relative expression of viral proteins. We explored whether differences in this axis among viral isolates affect transmission fitness. Methods HIV sequences were identified from nine female-to-male transmission pairs. Using a rapid flow cytometric assay, we analyzed Rev-RRE functional activity of primary isolates. Results Rev-RRE activity was significantly lower in recipient viruses compared with corresponding donor viruses. In most transmission events, recipient virus Rev-RRE activity clustered at the extreme low end of the range of donor virus activity. Conclusions These data indicate selection pressure on the Rev-RRE axis during female-to-male sexual transmission. Variation in Rev-RRE activity may permit viral adaptation to different fitness landscapes and could play an important role in HIV pathogenesis.

Digital divide among elderly workers - a comparative study between public and private sectors in Melaka / Hafisah Yaakob, Wan Hartini Wan Hassan and Faridah Pardi

Dramatically developments in the electronic dissemination of information began in the last twenty years. However, majority of the world still do not have access to this information. The situation called digital divide is prevailing in many countries irrespective of developed countries nor developing countries (Zaitun A.B & Barbara Crump, 2005). There are several factors affecting the digital divide which are economic factors, geography, computer skills and language proficiency level of literacy and the internet can also cause this problem (Norizan, 2007). Malaysia was not spared in the face of the phenomenon of the digital divide among the people. There are some people who need ICT and communication and among these groups which are the elderly workers of public and private sectors. The digital divide will result in most of the elderly are not able to get information that can improve their lives. The key to improving social and economic life in the global environment today is through the access to information. Trends in population aging becomes a clear scenario is happening in developed countries and developing countries, and not least, Malaysia. In 1999, the world's population over the age of 60 years is estimated at around 355 million people and 61.2% were in developing countries. Expected in 2020, the world's older persons will increase to 1,000 million (1 billion) people. This is an increase of 75% compared with an increase of 50% for the entire world population. There are approximately 700 million senior citizens in developing countries (Source: Family Health Development Division).
