The term amyloidoma applies to localized deposits of amyloid in the absence of systemic amyloidosis. Skeletal and soft tissue amyloidomas are very rare and the pathogenesis is usually associated with lymphoproliferative disorders or because of local chronic inflammation. Due to the rarity of the disease and the limited application of proteomics for diagnostic purposes, it is difficult to find datasets of mass spectrometry-based characterization of amyloidomas. Here we report the histological and immunohistochemical features of four cases of musculoskeletal amyloidoma in association with laser capture microdissection (LCM) and bottom-up microproteomics. Proteomics techniques allowed to elucidate the nature of the amyloid protein deposit, improving the results obtained by immunohistochemistry (IHC). IHC results were confirmed in two cases while laser-capture microdissection coupled with bottom-up microproteomics was necessary to type the other two cases, for which IHC was inconclusive.

Numerical weather prediction (NWP) models are commonly used for wind power forecasts, but NWP forecasts are uncertain due to uncertainties in the initial conditions, approximate model physics, and the chaotic nature of the atmosphere. Ensemble prediction systems (EPS), which simulate multiple possible futures, thus provide valuable information about forecast uncertainties. However, the spatial resolution of global ensemble forecasts from the European Centre for Medium-range Weather Forecast (ECMWF) and the National Centers for Environmental Prediction (NCEP) is relatively coarse and insufficient for many wind power farms built in complex terrain. This work proposes using the Weather and Research Forecasting model (WRF) to downscale ECMWF EPS and NCEP global ensemble forecast system (GEFS) to determine and compare the added values of downscaling different global EPS forecasts for wind forecasts in the complex terrain of Sichuan and Yunnan in China. A total of 366 days of day-ahead forecasts (28 to 51 hours) for wind speed at 80 meters are evaluated. The results demonstrate that the ensemble average of the higher resolution WRF downscaled forecast is considerably better than that of the global EPS forecast, and downscaled forecast of ECMWF EPS achieves the best performance. Also, a selective ensemble average (SEA) method is proposed and applied for the ultra-short (10 to 13 hours) forecast. Verification results demonstrate that the SEA method outperforms the ensemble mean.

Cybercrime has quickly become one of the most pressing issues to mitigate as more reliance on technology is created each day. Advanced persistent threat groups have established themselves as critical threats to organizations and governments as the sophistication of their attacks advances as technology does. One of the most significant threats currently is advanced persistent threat groups that originate from the country of China. China has some of the highest numbers of known advanced persistent threat groups, such as Double Dragon (APT41), PLA Unit 61398 (APT1), and now a new and emerging group dubbed HAFNIUM has been discovered.

Photoelectrochemical (PEC) water splitting has attracted strong interest as sustainable technology by converting solar energy into hydrogen. The semiconductor photoelectrodes play an important role to crease the solar-to-hydrogen conversion efficiency. Bismuth vanadate (BiVO4) is an excellent candidates as a photoanode material for PEC water oxidation because of its visible light absorption, suitable band edge location, high stability and low cost. However, single BiVO4 may undergo short carrier diffusion length, rapid recombination of photoinduced charge carriers and photocorrosion. Heterojunction strategy established by two or more materials has provided an outstanding scheme to mitigate these inadequacies. This review focuses on recent important works with respect to BiVO4 heterojunction photoanodes for PEC water oxidation reactions, including interface junction and surface functional junction. In the end, the challenges and prospects for future research on BiVO4 heterojunction photoanodes in solar-to-hydrogen application field are proposed.

On December 7 th of 2022, the province and the country experienced a huge adjustment of the prevention and control measures against SARS-CoV-2, which was called the ten actions. But we still performed regular SARS-CoV-2 nucleic acid testing for hospitalized patients before their admission, which could to some extent reflect the infection rates of the total society. A total of 2212 cases and 439 positive cases were enrolled in the study. The infection rate increases from the first to the third week, and then decreases from the third to the eighth period. The infection rate of the eighth week returned nearly to the rate of the first week. The adjustment on the prevention and control measures resulted in rapid increase of SARS-CoV-2 infection rate among hospitalized children through the first three weeks, and it took nearly eight weeks for the infection to recover to the rate at the beginning of the adjustment. Continuous monitoring of the infection is required in the future to help reduce the infection.

To critically review, analyze, and synthesize the literature surrounding the impact of parental burden, stress, and burnout on children and youth with cerebral palsy (CP). Background Parents of children with CP experience more stress and symptoms of burnout compared to parents of children without a disability. Although the impact of a child’s disability on the parent has been examined, little is known about the subsequent impact their stress has on their kin. Methods Databases including CINAHL, Embase, Medline, Nursing and Allied Health, PsycInfo, and Scopus were searched. Title, abstract, and full manuscript review were completed by two reviewers. Studies were evaluated for quality using the Joanna Briggs Institute Critical Appraisal Tools. Data from individual studies were synthesized and charted according to developmental domain. Results Overall, 18 articles met inclusion criteria. After quality appraisal, 15 with low to moderate risk of bias were included in the final analysis. Overall, studies included determined that parental stress worsens a child’s outcome, regardless of developmental domain assessed. Conclusion Parental stress has a negative influence on behavioural, physical, and occupational outcomes for children with CP. Additional research is needed to better understand the impact prolonged parental stress has on these and other developmental domains.

Atherosclerosis is a complex pathological process that is based on the chronic inflammatory reaction of the blood vessel wall and involves various immune cells and cytokines. The imbalance in the proportion and function of effector CD4 + T cell (Teff) and regulatory T cell (Treg) subsets is an important cause of the occurrence and development of atherosclerotic plaques. Teff cells depend on glycolytic metabolism and glutamine catabolic metabolism, while Treg cells mainly rely on fatty acid oxidation (FAO) for energy, which is crucial for determining the fate of CD4 + T cell differentiation and maintaining their respective immune functions. Here, we review recent research achievements in the field of immunometabolism related to CD4 + T cell, focusing on the cellular metabolic pathways and metabolic reprogramming involved in the activation, proliferation and differentiation of CD4 + T cell. Subsequently, we discuss the important roles of mTOR and AMPK signaling in regulating the fate of CD4 + T cell differentiation. Finally, we evaluate the links between CD4 + T cell metabolism and atherosclerosis, highlighting the potential of targeted modulation of CD4 + T cell metabolism in the prevention and treatment of atherosclerosis in the future.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder with variable disease courses and multiple clinical manifestations [1]. The etiology of SLE is not clear, but different environmental (ultraviolet [UV] light, infections, drugs), genetic, and hormonal factors all seem to be involved [1]. Positive family history and history of having other autoimmune illnesses are considered high-risk factors for SLE, but most SLE cases are scattered [1]. The 2019 EULAR/ACR classification criteria for SLE include positive ANA at least once as a mandatory entry criterion; followed by additive weighted standards grouped in seven clinical (constitutional, hematological, neuropsychiatric, serosal, musculoskeletal, renal, mucocutaneous ) and three immunological (antiphospholipid antibodies, complement proteins, SLE-specific antibodies) domains, and weighted from 2 to 10, and patients accumulating ≥10 points are classified to have SLE [2]. Herein, we report this case of neuropsychiatric lupus as it is uncommon and is a severe form of SLE.

Background: Here we conducted this study to find the changes in the hematological parameters of healthy individuals that can predict their immune status, also this study aims to find out whether herd immunity against COVID-19 is developing or not in the Pakistani population. Methods: A comparative cross-sectional study of 210 healthy individuals was conducted. All individuals were divided into three groups i.e IgG positive, IgG negative, and IgG and IgM both positive based on ELISA results. Data analysis was done by SPSS version 25 for windows. Results: A statistically significant effect was found among the three groups in terms of mean hemoglobin level, mean hematocrit, mean corpuscular hemoglobin concentration, mean red blood cells count, RDW-CV, mean lymphocyte, mean neutrophil, mean eosinophils, and mean basophil. The study also showed that 52.8% (n=74) had neither taken vaccination nor had any history of previous covid infection but still their antibodies were positive. Conclusion: There was a statistically significant difference among hematological parameters between immune and nonimmune groups and can predict the covid immune status also the study predicted that herd immunity against COVID-19 is developing in Pakistan.

In this work, we designed and synthesized two new 3-D pillared metal–organic frameworks (MOFs) [Cd2(adc)2(bpp)3∙4H2O]n (1) and [Cd2(adc)2(bpp)3]n (1b) with a 2-D breathing mode of reversible dehydration–rehydration. The dynamic behavior between 1 and 1b was detected by in situ single-crystal XRD analysis, which demonstrated that this 3-D pillared MOF contracted and expanded in two dimensions accompanied by dehydration–rehydration. Additionally, 1b exhibited faster water vapor response compared to commercial silica gel desiccant at normal temperature (21 °C) and humidity (RH% 50), which was detected by in situ IR. Therefore, the results suggests that this kind of flexible 3-D pillared metal–organic framework of 1 and 1b would be a reliable sensor for monitoring water vapor. (H2adc = 4,4’-azodibenzoic acid, bpp = 1,3-di(4-pyridyl)propane)

Background: T cell chemokines and its receptors play important roles in the development and progression of rheumatoid arthritis (RA). Their involvement has been reported in inflammatory autoimmune diseases. However, their role in RA in the Ghanaian population has not been explored. We evaluated the intracytoplasmic CD4+ T cell chemokine receptors in rheumatoid arthritis patients in Ghana and determined their relationship with disease activity. Methods. This case control study included 48 newly diagnosed RA patients and 30 apparent healthy controls from the orthopaedic units of Komfo Anokye Teaching Hospital (KATH), Kumasi and Korle-Bu Teaching Hospital (KBTH), Accra, Ghana. A well-structured questionnaire was used to obtain sociodemographic data. Blood samples were also collected and processed for flow cytometric analysis. Statistical analyses were done using SPSS version 26.0 and R programming language. Results: This study found a significant difference in age group (p < 0.0001), marital status (p ¬= 0.0210), occupation (p = 0.0140), educational level (p = 0.0210) and religion (p = 0.0100) between RA patients and healthy controls. Moreover, haemoglobin level (p = 0.0010), waist circumference (p < 0.0001) and hip circumference (p = 0.0040) were significantly different between RA patients and healthy controls. RA patients had significantly lower levels of CD4+CD183+ compared to the control group (p < 0.001), and was positively correlated with DAS score (r = 0.0397, p = 0.789). In Receiver Operator Characteristics analysis, CD4+CD183+ could significantly detect rheumatoid arthritis with a very high area under the curve (AUC = 0.687, p = 0.018). At a cut-off of 0.082, CD4+CD183+ was the best chemokine receptor for detecting RA with a sensitivity of 90.0%, specificity of 25.9%, a positive predictive value of 69.2%, and a negative predictive value of 58.3%. Conclusion: CD4+CD183+ could serve as useful diagnostics and disease-monitoring marker for rheumatoid arthritis in the Ghanaian population.

Primulina ganzhouensis (Gesneriaceae) is described and illustrated here as a new species. This new species resembles P. yangshanensis W.B.Xu & B.Pan, but it is distinct from the latter by some obvious features in leaf blade, bract, indumentum, corolla, filament, stigma and pistil. Nuclear ribosomal internal transcribed spacer (ITS) region and plastid trnL-F intronspacer (trnL-F) DNA sequence data from the new species and its 188 relatives are used to determine the systematic position of the new species within Primulina. Molecular evidence suggests that P. ganzhouensis is strongly supported as a sister to a clade in which P. yangshanensis is included. The conservation status of P. ganzhouensis is assessed as ” Endangered” (EN) according to IUCN Red List categories and criteria.

Sense enables babies to perceive the physical and chemical changes that occur in the external environment. It occurs as a result of the dynamic interaction of sensory stimuli with sensory receptors in the eyes, ears, tongue, nose, and skin. The stimuli that newborns see, touch, and hear affect their brain development. The brain develops faster in the early years than in other years. Newborns have a vestibular system, proprioceptive sense, neonatal imitation, and special senses that help them understand the world. Some babies’ senses are more sensitive than others. Each baby develops differently. The interaction that the baby will establish with his/her environment early on is invaluable for supporting its development. Their senses are stimulated from birth by the warm intimacy and contact established with the adult and the rich stimulating environment. Stimulation of the senses is critical to supporting the baby’s holistic development. This study discusses the relationship between interaction and the development of the sensory system in babies and offers suggestions for families and educators.

Indigofera jodhpurense sp. nov. (Fabaceae), which grows in arid places and wasteland near to the edge of Jodhpur in the direction of Pali, Rajasthan, India, is described. Although the species is similar to Indigofera cordifolia and I. jaisalmerica, it differs from these in having profusely hairy juvenile twigs, various types of trichomes on leaf surfaces, and sub-sessile flowers, straightened mucro at the tips of the leaves, and pods that are often single-seeded but can also be bi-seeded. The current communication includes a key to species, a comparative morphological analysis, and some photographs.

Physicians and scientists hope that health-data will provide new insights into improving medical care and optimizing healthcare costs. However, data protection laws in Europe often place limits on the use of patient data. During the COVID-19 pandemic, both digital immunity records and data on infections were needed for pandemic management. Using this example, the research project aims to create a system concept for vaccination, testing, and recovery proof called P3VT (Privacy Preserving Pass for Vaccination and Testing), that will make collected data available to research and policy pandemic management in real time and anonymized. P3VT was developed consistently considering the goals of privacy-by-design, data minimisation and transparency of the EU-GDPR. Expert interviews validated the system from medical, technical and privacy perspectives. P3VT offers the following advantages compared to the EU digital COVID certificate: Pseudonymized proof of vaccination, testing, and recovery, reducing misuse of sensitive personal data Transparency about the nature, timing, and purpose of the proof strengthens user trust Use of anonymous data improves pandemic management, and research P3VT is thus an exemplary solution for the comprehensive provision of health-data for research purposes in combination with high level of data protection. Further areas of application are conceivable.

Using a hydrothermal process, ZnO nanorods doped with varying amounts of Ag (0.1–0.5%) were created. The morphology and size of the nanorods (pure and doped ZnO) were observed by Scanning electron microscopy (SEM). According to the SEM micrographs the synthesized materials have nanorods structures with a size of about 131 nm and 208 nm for Undoped and doped ZnO nanorods respectively. Energy dispersive X-ray spectroscopy (EDX) were used to determined percentage composition of material. EDX analysis shows that Ag has been successfully decorated with the surface of ZnO lattice. The presence of functional groups was investigated by Fourier Transform Infra-Red (FTIR) spectroscopy while crystalline phase of the Ag doped ZnO Nanorods was analyzed by using X-ray diffractometry (XRD). The crystallinity and crystal plane location of the fabricated Nanorods were elucidated from the XRD pattern. It was found that the fabricated pristine and doped nanorods are crystalline in nature having a hexagonal wurtzite structure. Ag was added to the ZnO nanorods up to a predetermined dopant concentration limit. The incorporation of Ag in the sites present at the Zn nanomaterial caused to increase size of nanorods as compared to pure ZnO.

The possibility of using the transition state shape selectivity concept for control of selectivity of reaction was previously demonstrated by us using the example of 1,3-dioxanes formation by Prins reaction. The extension of the applied approach to other reactions is of theoretical and practical interest. Considering that the main channel for the formation of 1,3-dioxanes by Prins reaction is realized through a cyclic transition state, it is primarily interesting to study the applicability of the above approach to other reactions also proceeding through a cyclic transition state: Claisen rearrangement, Diels-Alder reaction, etc. The aim of our work was to study the interaction of the frozen transition state of Claisen rearrangement with the surface of nanotubes of various structures to predict their catalytic activity. Claisen rearrangement of allylphenyl ether was chosen as a model reaction, and carbon nanotubes with different diameters were chosen as a porous materials. The calculated dependence of the stabilization energy on the nanotube diameter has an extreme character with pronounced maxima at a diameter of 10.2–10.4 Å. The obtained results allow to predict the catalytic activity of nanotubes with a diameter of 10-11 Å in Claisen rearrangement of allylphenyl ether.

This study examined phylogenetic relationship, the taxonomic status and numerical morphometric analysis of 21 taxa of the genus Acer L. naturally found in Türkiye using the DNA sequence data of cpDNA ndhF, trnL-F and nrDNA ITS gene regions and 18 elucidative morphological characters. To date, no comprehensive molecular and morphological study dealing with the genus in Türkiye. Selected morphological traits of Dim1 (Leaf length, Leaf width, Petiole length, Loculus length, Loculus width, Fruit wing length and Fruit length) and Dim2 (Pubescence of leaf beneath, Margin, Latex and Form of nutles) are highly distinctive characters for the Acer genus in series and sectional levels. The nuclear (ITS) and chloroplast (trnL-F) gene regions were also found as quite diverse and informative. The results of phylogenetic and morphometric analysis revealed a relieable taxonomic clarification for the species Acer tauricolum, A. divergens (endemic to Türkiye), A. orthocampestre and A. cappadocicum subsp. cappadocicum. Chloroplast lineage of Acer species native to Türkiye appears to be originated in Oligocene and diversified mainly in Miocene. The majority of Acer speciation events in Türkiye is likely to be regulated by the habitats created by the by northern mountain ranges. Phylogenetically, the Acer species of Türkiye seemed to be closely related to the taxa from Asia and Europe.

Background: Heart transplantation (HTx) relies on an endomyocardial biopsy for rejection surveillance. Cell-free DNA (cfDNA) is released into the circulatory system from the cells of the recipient (recipient-derived rd-cfDNA) as well as from the graft (donor-derived dd-cfDNA) and is determined by the analysis of a blood test. There is growing evidence that the donor fraction (DF, the ratio of dd-cfDNA to all cfDNA) corresponds to the integrity of the graft. However, it is important that rd-cfDNA levels vary greatly in different, sometimes clinically silent circumstances, which in turn makes DF the sole measure of graft status vulnerable to bias. Methods: Using a digital PCR-based method that allowed us to quantify separate values of rd-cfDNA, dd-cfDNA, and DF, we investigated a prospective cohort of 52 patients during their first year after HTx. Results: We found median DF levels of approximately 0.1%, which is in accordance with the literature. We present patients with various clinical scenarios after HTx, including an uncomplicated clinical course, several infections (viral and bacterial), acute and chronic rejection, and false-negative and false-positive rejections. Conclusions: Quantification of circulating cfDNA reflects a live-view of cell turnaround in the recipient and graft. Measuring the DF alone may not be sufficient to fully understand the complex biology of cfDNA after HTx.

Background: As secretory phospholipase A2 (sPLA2) was shown to be elevated in patients who progress to severe dengue, it would be important to evaluate the usefulness of therapeutics that inhibit sPLA2 enzymes to prevent progression to severe dengue. Methods: Aqueous and butanol extracts of Tragia hispida, Justicia adathoda and tubers of Cyperus rotundus were screened for the presence of potential sPLA2 inhibitors using a commercial assay measuring sPLA2 activity. Results: Both the aqueous (THA) and butanol extracts (THB) of Tragia hispida had sPLA2 inhibition levels comparable to the levels seen with the commercial sPLA2 inhibitor CAY10590. THB at concentrations of 0.1 µg/µL and 0.2 µg/µL, significantly reduced the sPLA2 activity (p<0.0001) in the sera of dengue patients and the inhibitory activity was significantly higher (p<0.0001) than of CAY10590. Thin layer chromatography of THB showed that it was likely to contain a mixture of flavonoid and phenolic compounds. HPLC displayed peaks at 3.207 min (λmax 222 nm, 272 nm) and 7.972 min (λmax 224 nm, 272 nm) which were most likely to represent phenolics and peaks at 11.883 min (λmax 276 nm, 366 nm) and 16.898 min ( λmax 254 nm, 370 nm) which were most likely to represent flavonoids. Conclusions: T. hispida aqueous and butanol soluble fraction had potent sPLA2 inhibitory activities, which should be further explored for their potential to be used for treatment of dengue.

Background: Gestational duration has a non-negligible impact on eye diseases. However, the long-term role of cytokines on the causal relationship of maternal gestational age on offspring visual impairment remains unclear. Methods: We perform a lifecourse-network Mendelian randomization (MR) to explore the causal relationships among maternal gestational duration (from EGG and iPSYCH, N=84,689), neonatal/adult cytokines (from the NHGRI-EBI Catalog, N=764/4,618) and adult eye diseases (from FinnGen consotium, N=309,154) using summary-level data from large genome-wide association studies. Multiplicative random effects inverse variance weighted (IVW) and multivariable-IVW method are the main analysis methods and the other 15 pleiotropy-robust methods, weak IV-robust methods and outliers-robust methods are performed as auxiliary methods. Results: We find that maternal gestational age (early preterm birth, preterm birth, gestational duration and postterm birth) has causal relationships with 42 eye diseases. Specially, four neonatal cytokines: TNF-α, IL10, GROA and CTACK, as well as four adult cytokines: CTACK, IL10, IL12p70 and IL6.26 are mediators in the causal relationships between early preterm birth and preterm birth to 8 eye diseases. However, after adjusting for these mediators, null direct causal effect of early preterm birth and preterm birth on 8 eye diseases can be found. In addition, there is no mediator in the causal relationships from gestational duration and postterm birth to eye diseases. Conclusion: The influences of maternal gestational duration on the offspring eye diseases through cytokines are long-term and lifecourse.

Venous Thromboembolism (VTE) remains a significant cause of morbidity and mortality worldwide. Rivaroxaban, a direct oral factor Xa inhibitor, mediates anti-inflammatory and cardiovascular-protective effects besides its well-established anticoagulant properties; yet, these remain poorly characterized. Extracellular vesicles (EVs) are considered proinflammatory messengers regulating a myriad of (patho)physiological processes and may be highly relevant to the pathophysiology of VTE. The effects of Rivaroxaban on circulating EVs in VTE patients remain unknown. We have established that differential EV biosignatures are found in patients with non-valvular atrial fibrillation anticoagulated with Rivaroxaban versus warfarin. Here, we investigated whether differential proteomic profiles of circulating EVs could also be found in patients with VTE. We performed comparative label-free quantitative proteomic profiling of enriched plasma EVs from VTE patients anticoagulated with either Rivaroxaban or warfarin using a tandem mass spectrometry approach. Of the 181 quantified proteins, 6 were found to be either exclusive to, or enriched in, Rivaroxaban-treated patients. Intriguingly, these proteins form a cluster tightly involved in negative feedback regulation of inflammatory and coagulation pathways, suggesting that EV proteomic signatures may reflect both Rivaroxaban’s anti-coagulatory and anti-inflammatory potential. These findings may be of translational relevance towards characterizing the emerging anti-inflammatory and cardioprotective mechanisms associated with this therapy.
