The invention discloses aspergillus foetidus producing yellow pigment and application thereof. The Aspergillus foetidus is named Aspergillus foetidus (Aspergillus foetidus) HC32, and is deposited on the microorganism strain collection of Guangdong province, the university of Mitsui No. 100 building No. 5 building, the university of Guangzhou, china, at 2023, and deposited with the microorganism collection of Guangdong province, the accession number of which is GDMCC No. 63106. The aspergillus foetidus is a strain obtained by naturally fermenting and separating Xinhui dried orange peel, and the strain with high intracellular yellow pigment yield is obtained by ultraviolet mutagenesis. The natural yellow pigment with definite components can be prepared by fermenting the strain.
A mast cell surface antigen, DNA thereof and an antibody against the antigen are provided. The amino acid sequence of this mast cell surface antigen is the translation of the coding region of its DNA. The base sequence of this DNA has been clarified in the following manner. Namely, mast cells obtained by incubating cord blood monocular cells are co-incubated with primary culture of fibroblasts to give connective tissue type mast cells (MC-TC). Then mRNA is extracted from this MC-TC cell extraction and a cDNA library is constructed therefrom. Immunological screening is carried out with the use of anti-MC-TC antiserum and the base sequence of the positive clone thus obtained is identified. Owing to the clarification of the amino acid sequence of this mast cell antigen, it becomes possible to reveal the role of mast cells in the pathology of allergic diseases and thus an antibody against mast cells can be easily obtained.
The specific aim of this study is to validate the pharyngeal constriction ration, a surrogate measure of pharyngeal strength on fluoroscopy by comparing it with simultaneous pharyngeal manometry. Combined videofluoroscopic swallowing studies with pharyngeal manometry are commonly used in the evaluation of dysphagia. However, no published study has compared the results of simultaneous pharyngeal manometry with objective timing and displacement measures on videofluoroscopy. These objective measures, such as the pharyngeal constriction ratio, were developed here at UCD and are not yet routinely used by other practitioners. A secondary aim of this study will be to corroborate recent data in the literature suggesting that the presence of feeding tube through the upper esophageal sphincter does not affect the oropharyngeal phase of deglutition. This topic is currently under hot debate in the speech language pathology realm and has important implications for the evaluation of hospitalized patients with dysphagia.
This single-center study is conducted to compare the effect of peroperative transfusion of allogeneic unmodified RBC (UN-RBC) versus leuko-reduced RBC (RED-RBC) on recipient immunity. Patients undergoing cancer surgery are randomly assigned peroperatively to receive UN-RBC or RED-RBC. Groups are stratified for age, sex, tumor characteristics, prior transfusion and prior cancer treatment. Blood sampless are collected before anesthesia (d0) and at days 3, 7, 14 , 28 after transfusion/surgery and analyzed for complete cell blood count, lymphocyte subsets, cytokine production (IL4, IL10, IFNgamma, IL12), T-cells repertoire (TCR) analysis and detection of circulating donor cells. Main study endpoint is the influence of the treatment arm on IL4/IFNgamma ratio. The effect of transfusion type on any given biological parameters is also tested (peripheral blood mononuclear cell phenotyping (PBMC), cytokine production by stimulated PBMC, T cell repertoire analysis and microchimerism assessment).

INTRODUCTION: Despite the high number of operations and surgical advancement, rehabilitation after rotator cuff repair has not progressed for over 20 years. The traditional cautious approach might be contributing to suboptimal outcomes. Our aim is to assess whether individualised (early) patient-directed rehabilitation results in less shoulder pain and disability at 12 weeks after surgical repair of full-thickness tears of the rotator cuff compared with current standard (delayed) rehabilitation.
METHODS AND ANALYSIS: The rehabilitation after rotator cuff repair (RaCeR 2) study is a pragmatic multicentre, open-label, randomised controlled trial with internal pilot phase. It has a parallel group design with 1:1 allocation ratio, full health economic evaluation and quintet recruitment intervention. Adults awaiting arthroscopic surgical repair of a full-thickness tear are eligible to participate. On completion of surgery, 638 participants will be randomised. The intervention (individualised early patient-directed rehabilitation) includes advice to the patient to remove their sling as soon as they feel able, gradually begin using their arm as they feel able and a specific exercise programme. Sling removal and movement is progressed by the patient over time according to agreed goals and within their own pain and tolerance. The comparator (standard rehabilitation) includes advice to the patient to wear the sling for at least 4 weeks and only to remove while eating, washing, dressing or performing specific exercises. Progression is according to specific timeframes rather than as the patient feels able. The primary outcome measure is the Shoulder Pain and Disability Index total score at 12-week postrandomisation. The trial timeline is 56 months in total, from September 2022.
TRIAL REGISTRATION NUMBER: ISRCTN11499185.
BACKGROUND: Yi-Qi-Huo-Xue Decoction (YQHXD), a traditional Chinese medicine formula, has demonstrated efficacy in the clinical treatment of intracerebral hemorrhage (ICH) for over a decade. Nevertheless, the precise pharmacotherapeutic compounds of YQHXD capable of penetrating into cerebral tissue and the pharmacological underpinnings of YQHXD remain ambiguous.
METHODS: The active components of YQHXD in rat brains was analyzed by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. The potential targets, pathways and biological progresses of YQHXD ameliorating ICH induced injury was predicted by network pharmacology. Moreover, collagenase-induced ICH rat model, primary cortex neurons exposed to hemin and molecular docking were applied to validate the molecular mechanisms of YQHXD.
RESULTS: Eleven active components of YQHXD were identified within the brains. Employing the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases, our investigation concentrated on the roles of autophagy and the BDNF/TrkB signaling pathway in the pharmacological context. The pharmacological results revealed that YQHXD alleviated neurological dysfunction, brain water content, brain swelling, and pathological injury caused by ICH. Meanwhile, YQHXD inhibited autophagy influx and autophagosome in vivo, and regulated cortex neuronal autophagy and TrkB/BDNF pathway both in vivo and in vitro. Subsequently, N-acetyl serotonin (NAS), a selective TrkB agonist, was employed to corroborate the significance of the BDNF/TrkB pathway in this process. The combination of NAS and YQHXD did not further enhance the protective efficacy of YQHXD in ICH rats. Additionally, outcomes of molecular docking analysis revealed that nine compounds of YQHXD exhibited potential regulatory effects on TrkB.
CONCLUSIONS: Ipsilateral neuronal autophagy and BDNF/TrkB pathway were activated 72 h after ICH. YQHXD effectively resisted injury induced by ICH, which was related with suppression of ipsilateral neuronal autophagy via BDNF/TrkB pathway. This study provides novel insights into the therapeutic mechanisms of traditional Chinese medicine in the context of ICH treatment.
This study is a randomised, placebocontrolled, doubleblind study on the effect of the antiepileptic drug, levetiracetam, in patients suffering from PMPS. The treatment periods are 1 month each and the periods are separated by a 1-week washout period. The daily dose of levetiracetam is increased over a 2-week period to 3.000 mg/day. The primary effect variable is pain relief by the use of numeric rating scale. Secondary parameters are daily registration of pain performed by the patients during the treatment periods and the amount of escape medicine used (paracetamol and tramadol). Sensory testing is performed at baseline and after each treatment period.
This single-arm trial will enroll patients with biopsy confirmed or a high clinical suspicion of a lung malignancy based on MRI, CT and/or PET imaging. A total of up to 40 patients will be enrolled in this trial. The sponsor reserves the right to perform an interim analysis following early enrollment (i.e., n ≤ 10 subjects) to determine the feasibility and benefit of pegsitacianine as an adjunct to standard of care surgical resection of lung malignancies.

The surgeon will begin by attempting to perform their SOC tumor resection. If the tumor is unable to be located under standard white light conditions, an appropriate FDA-cleared near-infrared imaging device may be used to aid in the location of the primary tumor. Localization of the primary tumor, when unable to be located using white light imaging, in conjunction with pathology confirmed presence of disease will be considered a clinically significant event. Following any standard of care procedures conducted under white light only, the near infrared camera will be used to evaluate areas of residual fluorescence that may be resected if suscpicious for metastatic spread or residual margins. The fluorescence status of each specimen will then be correlated to the final pathology for each, and performance metrics of pegsitacianine will be tabulated.
AIMS: Advances in type 1 diabetes management are enabling more to reach older ages. Frailty is known to complicate type 2 diabetes. However, frailty in people with type 1 diabetes has not been extensively researched. This review summarises the available evidence on frailty in those with type 1 diabetes.
METHODS: A systematic search strategy was applied to multiple databases (Medline, Embase, CINAHL and Cochrane) including grey literature (Scopus, OAIster, OpenGrey, dissertation and thesis database). All evidence types were considered. English articles published after 2001 were eligible. For inclusion, participants must have been over 55 with type 1 diabetes. Frailty must have been clearly defined or assessed. The results were synthesised into a descriptive format to identify key themes.
RESULTS: Of 233 papers subject to full-text review, 23 were included. Older adult diabetes research frequently does not specify the type of diabetes; 100 articles were excluded for this reason. No articles were found specifically researching frailty in older adults with type 1 diabetes. Fourteen different definitions and nine assessments of frailty were outlined. Generally, the papers supported relaxation of glucose targets and greater adoption of diabetes technology.
CONCLUSIONS: This review highlights the paucity of evidence in older adults with type 1 diabetes and frailty. Consensus on standardised definitions and assessments of frailty would aid future research, which is urgently needed as more people with type 1 diabetes reach older ages. Identifying and addressing the key issues in this population is vital to support individuals through the challenges of ageing.
The present invention relates to a novel DNA-RNA hybrid regular tetrahedron structure or an RNA tetrahedron structure capable of being utilized in controlling the expression of a target gene or delivering a drug. More specifically, the present invention relates to a DNA-RNA hybrid regular tetrahedron structure or an RNA regular tetrahedron structure including a small interfering RNA (siRNA) or microRNA (miRNA) sequence of a target gene. According to the present invention, a functional RNA nano-structure in which siRNA or miRNA is introduced is provided, so the structure is autonomously delivered into a cell at high efficiency. An RNA interference mechanism is induced, and apoptosis of a target cell can be induced. Moreover, provided is a controllable structure, in which a drug is dipped in a cavity, so the drug is discharged to the outside. Furthermore, an RNA nano-structure inducing apoptosis of a target cell is produced by using RNA interference through the technique of the present invention as a fundamental technique, so it is expected that the RNA nano-structure can be commercialized as a new drug.
The HLA region, especially HLA class I and II genes, which encode molecules for antigen presentation to T cells, plays a major role in the predisposition to autoimmune disorders. To clarify the mechanisms behind this association, we examined genome-wide DNA methylation by microarrays to cover over 850,000 CpG sites in the CD4+ T cells and CD19+ B cells of healthy subjects homozygous either for DRB1*15-DQA1*01-DQB1*06:02 (DR2-DQ6, n = 14), associated with a strongly decreased T1D risk, DRB1*03-DQA1*05-DQB1*02 (DR3-DQ2, n = 19), or DRB1*04:01-DQA1*03-DQB1*03:02 (DR4-DQ8, n = 17), associated with a moderately increased T1D risk. In total, we discovered 14 differentially methylated CpG probes, of which 10 were located in the HLA region and six in the HLA-DRB1 locus. The main differences were between the protective genotype DR2-DQ6 and the risk genotypes DR3-DQ2 and DR4-DQ8, where the DR2-DQ6 group was hypomethylated compared to the other groups in all but four of the differentially methylated probes. The differences between the risk genotypes DR3-DQ2 and DR4-DQ8 were small. Our results indicate that HLA variants have few systemic effects on methylation and that their effect on autoimmunity is conveyed directly by HLA molecules, possibly by differences in expression levels or function.
Patients randomized into this group will also receive the standard handout explaining their result. Within 1-2 weeks after their mammogram appointment, patients will receive a phone call from a genetics counseling staff person to explain their screening result and to offer to set up a genetics counseling appointment. This call may take up to 10 - 15 minutes.
Vivent Health is a non-profit medical home model dedicated to the primary care of People Living with HIV (PLWH) and also provides pre-exposure prophylaxis (PrEP), Hepatitis C, and sexually transmitted infection (STI) treatment. The organization has clinics in Wisconsin (multiple cities), Denver, St. Louis, Austin and Kansas City. All insurances except Kaiser are honored and non-insured people are able to be seen. The Denver medical clinic is a designated medical home that provides adult primary medical and specialty care to approximately 1000 + PLWH. In additional to medical care, this clinic has an onsite pharmacy, case management, HIV and Hepatitis C prevention department, syringe access program, legal department, housing specialists, food bank, a mental health program and dental services. Vivent Health in Denver cares for a diverse population with approximately 11% African-American, 13% Latino, and a recently increasing percentage of women around 13%. This clinic has a strong Electronic Health Record System (EHR- Epic) which provides ample opportunity to recruit a robust study population to investigate the following co-morbidities which might increase the risk of oral HPV infection and related lesions. Given the lack of recommended routine screening for oral HPV in the absence of established masses or lesions, there is a wealth of opportunities to investigate risk factors associated with the presence and prevalence of oral HPV which, in turn, can potentially be used to inform screening and treatment protocols. This proposal is designed to evaluate the prevalence of oral HPV infections and associated oral lesions and associated demographics in HIV treatment clinic.
The invention discloses a medicinal extract for treating facial nerve paralysis. The facial nerve paralysis is also called as facial neuritis and is commonly known as prosopoplegia, after suffering from the facial nerve paralysis, a patient has distortion of the face, slobbers and has strange and stiff facial expressions, and some patients further suffer from sequelae such as prosopospasm and prosopalgia after being treated, and feel tearing pain. Pathogenesis of the facial nerve paralysis is complex, and treatment difficulty is high. Treatment to the facial nerve paralysis is a worldwide difficulty. When in western medical surgery, the patients feel painful; and when treated by traditional Chinese medical acupuncture, a curative effect is slow, sufferings of the patients are great, and cure rate is low. The medicinal extract is ingenious in compatibility, the patients do not feel painful during treatment, a treatment course is short, a curative effect is remarkable, adaptability is high, toxic and side effects are avoided, economic pressure and mental pressure of the patients can be relieved, effective rate of treating the facial nerve paralysis, the prosopospasm and the prosopalgia reaches 98%, and the cure rate is higher than 90%.
The direct electric current will apply through a pair of sponges humidified with saline solution (150 mMols of NaCl diluted in water Milli-Q) on the electrodes (35 cm2). The electrodes (anode and cathode) will be connected to a continuous electric stimulator (Model: Microestim Foco Research, Brand: NKL, Souza Cruz, Brusque - SC, Brazil), with one energy battery (9 V) and will be mounted in accordance with the International 10-20 EEG System. For the sham condition, the electrodes will be placed at the same positions as for the anodal tDCS. However, the stimulator will turn off after 30 s of stimulation. As a result, subjects will report the same sensory feelings from the beginning of the real tDCS conditions, specifically itching and tingling feelings on the scalp for the first few seconds of tDCS, but not thereafter, whether or not the stimulation will continue or stop.
BACKGROUND: Peritoneal dialysis (PD) offers quality of life and empowerment for persons with end-stage kidney disease (ESKD). Nevertheless, the prevalence of PD is low in Belgium and Europe in general. Reimbursement, patient mix and late referral have been quoted as underlying reasons. However, to date no one-size-fits-all solution increasing uptake of PD has been successfully implemented. We aimed to understand the nephrologist's perspective, beliefs, and experiences on dialysis modality selection and to clarify underlying process-level and intrinsic motivations steering final decisions.
METHODS: Using purposeful sampling, Belgian nephrologists (non-/academic, geographical spread, age, gender) were selected. We conducted semi-structured interviews, and audiotapes were transcribed verbatim. Meaningful units were grouped into (sub-)themes, and a conceptual framework was developed using grounded theory according to Charmaz as guidance.
RESULTS: Twenty-nine nephrologists were interviewed. We identified four themes: Trust and belief (in PD as a technique; own expertise, knowledge and team; in behavior of patient, family practitioner), feeling of control (paternalism; insecurity; prejudice), vision of care and approach (shared decision making; troubleshooting attitude; flexibility and creativity; complacency), and organizational issues (predialysis; access; financial; and assisted PD).
CONCLUSIONS: Based on these interviews, it is apparent that next to already identified singular issues such as late referral, predialysis education, patient mix and financial incentives, more intrinsic factors also impact uptake of home-based therapies. These factors intertwine and relate both to process-level topics and to attitudes and culture of the nephrologists within the team.

The interventions composed of performing two additional recess program lasting 30 minutes outside the classroom that encouraged children to go outside for outdoor activities during recess in both the morning and afternoon during school days within a intervention period of 1 school year.
Pill aspiration is a significant source of foreign body aspiration in the United States and can occur without swallowing dysfunction or illness. Consequences depend on various factors, such as the pill's chemical composition, size, and diagnostic delay. Aspiration of iron tablets poses a higher risk because of hydroxyl radical formation and subsequent caustic burns, inflammation, obstruction, and/or necrosis. We present a case of a middle-aged obese woman who died 3 weeks after aspirating an iron tablet. Autopsy revealed morbid obesity, a necrotic focus in the right middle lobe of the lung, bronchiolar granulation tissue with iron staining foreign matter, extending into an adjacent arteriole, and mural perforation of the hilar right middle lobe. Despite seeking medical attention twice, the patient was only accurately diagnosed postmortem. This case highlights the importance of accurate and timely diagnosis in preventing fatal outcomes. To enhance diagnostic accuracy and reduce morbidity and mortality associated with pill aspiration, clinicians should maintain a high level of suspicion for foreign body aspiration in patients with persistent or worsening respiratory symptoms. Furthermore, it is crucial for forensic pathologists to have a high index of suspicion about the potential for lethal pill aspiration and complications days after the acute event.
Accurate determination of microsatellite instability (MSI) status is critical for tailoring treatment approaches for gastric cancer patients. Existing clinical techniques for MSI diagnosis are plagued by problems of suboptimal time efficiency, high cost, and burdensome experimental requirements. Here, we for the first time establish the classification model of gastric cancer MSI status based on Raman spectroscopy. To begin with, we reveal that tumor heterogeneity-induced signal variations pose a prominent impact on MSI classification. To eliminate this issue, we develop Euclidean distance-based Raman Spectroscopy (EDRS) algorithm, which establishes a standard spectrum to represent the "most microsatellite stable" status. The similarity between each spectrum of tissues with the standard spectrum is calculated to provide a direct assessment on the MSI status. Compared to machine learning-algorithms including k-Nearest Neighbors, Random Forest, and Extreme Learning Machine, the EDRS method shows the highest accuracy of 94.6 %. Finally, we integrate the EDRS method with the clinical diagnostic modality, computed tomography, to construct an innovative joint classification model with good classification performance (AUC = 0.914, Accuracy = 94.6 %). Our work demonstrates a robust, rapid, non-invasive, and convenient tool in identifying the MSI status, and opens new avenues for Raman techniques to fit into existing clinical workflow.
