Warming Yang promoting blood circulation and diuresis (WYPBD) has been proven effective in treating some diseases. This study aimed to evaluate therapeutic effect of WYPBD in treating chronic heart failure (CHF). CHF rats were established by intraperitoneally injecting doxorubicin (DOX). Therapeutic effects of WYPBD on cardiac function and hemodynamic parameters of myocardial tissues were analyzed. Collagen fiber production and myocardial fibrosis were evaluated. Transcriptions of COL1A1 gene, COL3A1 gene, and TGFB1 gene were evaluated with RT-PCR. Expression of BNP, AVP, PARP, caspase-3, and Bcl-2 in myocardial tissues were evaluated. TUNEL assay was used to identify apoptosis of cardiomyocytes. WYPBD alleviated degree of myocardial hypertrophy in CHF rats compared to the rats in CHF model group (P < 0.05). WYPBD significantly improved cardiac hemodynamics (increased LVEF and LVSF) of CHF rats compared to rats in the CHF model group (P < 0.05). WYPBD protected myocardial structure and inhibited collagen fiber production in myocardial tissues of CHF rats. WYPBD markedly decreased myocardial fibrosis mediators (Col1α, Col3α, TGF-β1) transcription in myocardial tissues of CHF rats compared to rats in CHF model group (P < 0.05). WYPBD significantly reduced BNP and AVP expression in myocardial tissues of CHF rats compared to rats in the CHF model group (P < 0.05). WYPBD markedly reduced the expression of PRAP and caspase-3, and increased Bcl-2 expression in myocardial tissues of CHF rats compared to rats in the CHF model group (P < 0.05). In conclusion, WYPBD alleviated CHF myocardial damage by inhibiting collagen fiber and myocardial fibrosis, attenuating apoptosis associated with the mitochondria signaling pathway of cardiomyocytes.
BACKGROUND: Urinary tract infections (UTI) affect almost two-thirds of all women during their lives and many experience recurrent infections. There are evidence-based guidelines from multiple international societies for evaluation and treatment; however, recent claims-based analyses have demonstrated that adherence to these guidelines is poor. This study seeks to understand the barriers experienced by U.S. primary care providers (PCPs) to providing guideline-based care for UTI and recurrent UTI (rUTI).
METHODS: Semi-structured interviews of 18 PCPs, recruited from the greater Los Angeles area, examined real-world clinical management of UTI/rUTI episodes, decisions to refer to subspecialty care, and resources guiding counseling and management. Grounded theory methodology served to analyze interview transcripts and identify preliminary and major themes.
RESULTS: Participants expressed the desire to obtain urine cultures for each cystitis episode, but felt pressured to make compromises by patient demands or barriers to care. PCPs had lower thresholds to empirical treatment if patients had a history of rUTIs, were elderly, or declined evaluation. Laboratory data was minimally utilized in clinical decision-making: urinalyses were infrequently considered when interpreting culture data. PCPs treated a broad set of urologic and non-urologic symptoms as UTI, even with negative cultures. PCPs did not feel comfortable initiating UTI prophylaxis, instead seeking specialist evaluation for anatomic causes. They were unaware of management guidelines, typically utilizing UpToDate® as their primary resource. Few evidence-based UTI prevention interventions were recommended by providers.
CONCLUSIONS: Low availability of succinct and clear professional guidelines are substantial barriers to appropriate UTI/rUTI care. Poor useability of clinical guidance documents results in substantial confusion about the role of preventative measures and additional diagnostic testing. Difficulties in patient access to care providers lead to expectations for presumptive treatment. Future studies are needed to determine if improved educational materials for providers and/or management algorithms can improve guideline concordance of UTI management.
In En-Bloc Resection of Bladder Tumours (ERBT), tumours are not removed in fragments, but are dissected in one layer and, if possible, extracted in one piece. This method represents a significant shift in the surgical management of non-muscle-invasive bladder tumours, providing multiple benefits over the traditional transurethral resection of the bladder (TUR-B). The histological analysis of ERBT specimens is more accurate, enhancing diagnostic precision. Additionally, the presence of detrusor muscle in ERBT specimens is more frequent, indicating a more complete removal of the tumours. Recent years have seen the consolidation of a robust evidence base emphasizing the advantages of ERBT. Notably, a multicentric, prospective randomized trial has recently revealed a significant reduction in recurrence rates at 12 months follow-up compared with TUR-B. Experienced endourologists should explore this technique, as it may soon become the standard of care. The technique's elegance and effectiveness make it too important to be ignored.
Osteosarcoma (OS) is the most common primary malignant tumour of the bone with high mortality. Here, we comprehensively analysed the hypoxia signalling in OS and further constructed novel hypoxia-related gene signatures for OS prediction and prognosis. This study employed Gene Set Enrichment Analysis (GSEA), Weighted correlation network analysis (WGCNA) and Least absolute shrinkage and selection operator (LASSO) analyses to identify Stanniocalcin 2 (STC2) and Transmembrane Protein 45A (TMEM45A) as the diagnostic biomarkers, which further assessed by Receiver Operating Characteristic (ROC), decision curve analysis (DCA), and calibration curves in training and test dataset. Univariate and multivariate Cox regression analyses were used to construct the prognostic model. STC2 and metastasis were devised to forge the OS risk model. The nomogram, risk score, Kaplan Meier plot, ROC, DCA, and calibration curves results certified the excellent performance of the prognostic model. The expression level of STC2 and TMEM45A was validated in external datasets and cell lines. In immune cell infiltration analysis, cancer-associated fibroblasts (CAFs) were significantly higher in the low-risk group. And the immune infiltration of CAFs was negatively associated with the expression of STC2 (P < 0.05). Pan-cancer analysis revealed that the expression level of STC2 was significantly higher in Esophageal carcinoma (ESCA), Head and Neck squamous cell carcinoma (HNSC), Kidney renal clear cell carcinoma (KIRC), Lung squamous cell carcinoma (LUSC), and Stomach adenocarcinoma (STAD). Additionally, the higher expression of STC2 was associated with the poor outcome in those cancers. In summary, this study identified STC2 and TMEM45A as novel markers for the diagnosis and prognosis of osteosarcoma, and STC2 was shown to correlate with immune infiltration of CAFs negatively.
Over 500,000 adolescents sustain mild traumatic brain injuries (aka "concussions") in the US each year. Despite the term "mild," concussion symptoms disrupt all aspects of an adolescent's functioning, from school to friendships to family, and impair quality of life. Although many youth recover quickly, \~1/3 still have protracted postconcussive symptoms (PPCS) a month or later post-injury. PPCS are hard to treat medically, as concussion-induced pathophysiology wanes within 1-3 weeks. Instead, contemporary treatments seek to target modifiable patient behaviors that contribute to PPCS. There is accumulating evidence that poor sleep quality or quantity are under-addressed, potent, treatable contributors to PPCS, particularly for adolescents. Indeed, recent studies suggest that targeted behavioral sleep treatments can improve adolescent sleep and other persistent post-concussive symptoms, but published approaches have required 4-6 treatment sessions delivered months post-injury. Such approaches are costly and onerous for families, fit poorly with integrated care models, and leave youth and their families to suffer months of protracted PPCS burden. In contrast, our team has developed a single-session behavioral sleep intervention for adolescents that is designed to be delivered soon after acute pathophysiology wanes (4-7 weeks post-injury) to head off protracted symptom burden. Preclinical and Phase 1 studies suggest that this approach is feasible, well-accepted, and has the potential to improve both sleep and other PPCS. Our long-term plan is to test the effectiveness of that intervention in an applied setting. To justify and guide that large-scale trial, here we propose a Phase 2 clinical trial to definitively test the efficacy of the intervention in a controlled context. We will randomize 70 adolescents aged 12-18 years who are experiencing PPCS and poor sleep quantity or quality to receive either a 1-session sleep treatment (Tx) or care-as-usual (control) 4-7 weeks post-injury. We will assess sleep, PPCS, and real-world functioning just prior to randomization and then again 1 week and 1 month later. Our primary aim is to determine the short-term efficacy of the Tx in improving both sleep and PPCS. Secondarily, we will assess the sustained efficacy of the Tx and its impact on daily functioning. We will also explore potential effect modifiers (e.g., demographics, injury-related factors). To ensure successful completion of this study, we have assembled a team of experts in pediatric brain injury and PPCS, adolescent sleep research, behavioral sleep medicine, and biostatistics with a proven record of successful collaboration, including on similar studies and our Phase 1 trial. The current study represents an important next step in our research program, definitively testing efficacy in a Phase 2 trial prior to embarking on a larger (Phase 3) applied effectiveness study. If, as we propose, our brief intervention both improves sleep and reduces other PPCS, this could lead to a powerful new tool to accelerate the recovery and alleviate burden for hundreds of thousands of adolescents every year.
Supplemental O2 (hyperoxia) is a critical intervention for premature infants (<34 weeks) but consequently is associated with development of bronchial airway hyperreactivity (AHR) and asthma. Clinical practice shifted toward the use of moderate hyperoxia (<60% O2), but risk for subsequent airway disease remains. In mouse models of moderate hyperoxia, neonatal mice have increased AHR with effects on airway smooth muscle (ASM), a cell type involved in airway tone, bronchodilation, and remodeling. Understanding mechanisms by which moderate O2 during the perinatal period initiates sustained airway changes is critical to drive therapeutic advancements toward treating airway diseases. We propose that cellular clock factor BMAL1 is functionally important in developing mouse airways. In adult mice, cellular clocks target pathways highly relevant to asthma pathophysiology and Bmal1 deletion increases inflammatory response, worsens lung function, and impacts survival outcomes. Our understanding of BMAL1 in the developing lung is limited, but our previous findings show functional relevance of clocks in human fetal ASM exposed to O2. Here, we characterize Bmal1 in our established mouse neonatal hyperoxia model. Our data show that Bmal1 KO deleteriously impacts the developing lung in the context of O2 and these data highlight the importance of neonatal sex in understanding airway disease.
BACKGROUND/OBJECTIVES: Atherosclerosis is a chronic inflammatory disease of the arterial wall, which involves multiple cell types. Peptide OG-5 is identified from collagen hydrolysates derived from Salmo salar and exhibits an inhibitory effect on early atherosclerosis. The primary objective of this study was to investigate the impact of OG-5 on advanced atherosclerotic lesions as well as its stability during absorption.
METHODS: In this study, the ApoE-/- mice were employed to establish advanced atherosclerosis model to investigate the treatment effect of peptide OG-5.
RESULTS: The results showed that oral administration of OG-5 at a dosage of 150 mg/kg bw resulted in a 30% reduction in the aortic plaque formation area in ApoE-/- mice with few bleeding risks. Specifically, intervention with a low dose of OG-5 (50 mg/kg bw), initiated in the early stage of atherosclerosis, continues to provide benefits into the middle and late stages without bleeding risks. Furthermore, treatment of OG-5 increased expression levels of contractile phenotype markers and reduced the accumulation of lipoprotein in VSMCs induced by ox-LDL. Peptide OG-5 could ensure transport across Caco-2 cell monolayers, exhibiting a Papp value of 1.80 × 10-5 cm/s, and exhibited a robust stability in plasma with remaining content >70% after 8 h incubation. In vivo studies revealed that OG-5 reached maximum concentration in blood after 120 min.
CONCLUSION: The present results demonstrate the potential efficacy of peptide OG-5 as a promising agent for intervention in anti-atherogenesis strategies.
Urinary bladder cancer (BC) inflicts a significant impairment of life quality and poses a high mortality risk. Schistosoma haematobium infection can cause BC, and the urinary microbiota of BC patients differs from healthy controls. Importantly, intravesical instillation of the bacterium Bacillus Calmette-Guerin stands as the foremost therapy for non-muscle invasive BC. Hence, studying the receptors and signaling molecules orchestrating bacterial recognition and the cellular response in the context of BC is of paramount importance. Thus, we challenged Toll-like receptor 4 (Tlr4) and myeloid differentiation factor 88 (Myd88) knock-out (KO) mice with N-butyl-N-(4-hydroxylbutyl)-nitrosamine (BBN), a well-known urinary bladder carcinogen. Gut microbiota, gene expression, and urinary bladder pathology were followed. Acute exposure to BBN did not reveal a difference in bladder pathology despite differences in the animal's ability to recognize and react to bacteria. However, chronic treatment resulted in reduced cancer invasiveness among Myd88KO mice while the absence of functional Tlr4 did not influence BC development or progression. These differences correlate with a heightened abundance of the Faecalibaculum genus and the lowest microbial diversity observed among Myd88KO mice. The presented data underscore the important role of microbiota composition and MyD88-mediated signaling during bladder carcinogenesis.
Approximately 70% of lower extremity injuries occur during non-contact, single-leg landings, and jumping to the ground is a common injury mechanism in both genders. Additionally, female athletes have higher injury rates compared to men, potentially due to anatomical differences of the lower kinematic chain. Events in which athletes experience non-contact ACL injuries generally show many common biomechanical features such as increased ground reaction forces during single-leg landing, decreased joint flexion in the sagittal plane of the ankle, knee, hip and trunk, as well as increased knee internal rotation angles. Another critical ACL injury risk factor is performing a secondary task during sharp deceleration movements. Current rehabilitation programs focus on neuromuscular training programs to prevent adverse movement patterns and increase proper movement control. However, there is still a need to increase the effectiveness of these neuromuscular training programs to have a more significant impact on ACL injury rates. Therefore, the use of motor learning strategies and neuromuscular training programs with adequate and correct techniques in the rehabilitation of athletes should still be investigated.

There are various approaches to motor learning. One of the best-known approaches is the cognitive approach, where the athlete reaches the automation stage by receiving feedback and repeating the model technique as often as possible. The common denominator of motor learning strategies is the use of explicit instructions and feedback regarding desired landing positions. Instructions for the implementation of movements in rehabilitation programs aim to improve performance and motor learning. These instructions may address the action outcome or the course of action. There are many studies showing that feedback training changes jump landing biomechanics. In line with the results of these studies, using feedback techniques, especially to reduce the vertical ground reaction force and increase the knee flexion angle during landing from a jump, can reduce the stress and risk of injury in the lower extremity.

Motor skills can be learned with an internal focus of attention or with an external focus of attention. Although the difference in these instructions may seem insignificant, externally focused education; has been shown to result in better performance, retention, transfer, and greater movement automaticity. The main purpose of this study is to investigate the effects of training on vertical jump landing technique by comparing a verbal training group that receives instructions with an external focus of attention and an internal focus of attention combined, a visual training group with video instructions, and a control group in female athletes with knee valgus. It is also to examine whether possible beneficial results are still present in the retention test performed one week after the test session. The secondary aim of our study is to examine the effect of the training provided on knee joint position sense.
HER-2 positive breast cancer patients who live at high altitudes greater than 2000 meters for long periods of time and will receive trastuzumab-based targeted therapy will be enrolled. The subjects included early and advanced patients. Treatment regimens includes chemotherapy combined with trastuzumab, chemotherapy combined with trastuzumab and pertuzumab, trastuzumab alone, and trastuzumab plus pertuzumab. Electrocardiogram, cardiac ultrasound, NT-proBNP, and TNI will be tested every 3 months when the treatment begins. The primary endpoint is cardiotoxity. The second endpoints is pathologic complete response (pCR) rate in neoadjuvant therapy, objective remission rate (ORR) and disease control rate (DCR) in neoadjuvant and palliative therapy.
Epilepsy often occurs with other neurological disorders, such as autism, affective disorders, and cognitive impairment. Research indicates that many neurological disorders share a common pathophysiology of dysfunctional energy metabolism, neuroinflammation, oxidative stress, and gut dysbiosis. The past decade has witnessed a growing interest in the use of metabolic therapies for these disorders with or without the context of epilepsy. Over one hundred years ago, the high-fat, low-carbohydrate ketogenic diet (KD) was formulated as a treatment for epilepsy. For those who cannot tolerate the KD, other diets have been developed to provide similar seizure control, presumably through similar mechanisms. These include, but are not limited to, the medium-chain triglyceride diet, low glycemic index diet, and calorie restriction. In addition, dietary supplementation with ketone bodies, polyunsaturated fatty acids, or triheptanoin may also be beneficial. The proposed mechanisms through which these diets and supplements work to reduce neuronal hyperexcitability involve normalization of aberrant energy metabolism, dampening of inflammation, promotion of endogenous antioxidants, and reduction of gut dysbiosis. This raises the possibility that these dietary and metabolic therapies may not only exert anti-seizure effects, but also reduce comorbid disorders in people with epilepsy. Here, we explore this possibility and review the clinical and preclinical evidence where available.
The aim is to study is to evaluate doxycycline as a treatment for HHT with the proposed "HHT Clinical Trial Protocol". Rare disease presents a number of challenges in clinical trial design, including recruitment challenges, related power limitations and less knowledge about outcomes measurement. Considering these limitations, as well as the large variability in epistaxis measures across HHT patients, a crossover-trial design, with each subject receiving the study drug and placebo, and therefore serving as their own control, has been selected, including randomization and blinding, to limit bias in measuring this subjective outcome.

This study will investigate doxycycline, given its demonstrated anti-angiogenic and anti-inflammatory properties, as well as compelling effects in arteriovenous malformation (AVM) models. Doxycycline also has the advantages of a proven safety track record for long-term use, oral administration and low cost. Doxycycline suppresses vascular endothelial growth factor (VEGF)-induced cerebral matric metalloproteinase-9 (MMP-9) activity in vivo in the mouse model, and has anti-inflammatory effects as well, via inhibition of pro-inflammatory cytokines. In human brain vascular malformation tissue, there is evidence of increased expression of MMP-9 and VEGF and another tetracycline, minocycline, has attenuated brain hemorrhage in the mouse. Recently, a small retrospective case series reported sustained reduction in nasal hemorrhage in seven HHT patients treated with oral doxycycline. We hypothesize that oral doxycycline will reduce nasal hemorrhage in HHT subjects, through anti-angiogenic and/or anti-inflammatory mechanisms, both of which have been implicated in HHT.

This is a double-blind randomized placebo-controlled trial (N=30) of oral doxycycline (100mg twice daily, 6-month course) in HHT subjects with moderate-severe recurrent nasal hemorrhage. Drug dosing and safety monitoring will be tailored specifically to the agent studied. The primary outcome will be reduction of bleeding minutes per week. In addition, vascular malformation tissue (cutaneous) will be obtained pre and post-treatment, and stained for inflammatory, angiogenic and bone morphogenetic protein-9 (BMP9)-activin A receptor like type1(ALK1)-endoglin- Smad1/5/9 pathway markers. In addition, pre-excision, vascular malformations will be imaged with speckle variance optical coherence tomography (SVOCT), in vivo non-invasive micro-angiography to measure lesion structure, vessel volume and vessel density, as previously described. If the drugs studied are effective at reducing nasal hemorrhage, this will have important clinical implications for HHT patients, and the tissue and imaging may provide important insights into mechanisms.
PURPOSE: To obtain good catabolism by gelling a biologically active substance with intestinal mucus and gelling the substance in the presence of alginate and calcium. CONSTITUTION: The epithelium of digestive tracts is coated with mucus or mucin which protects the epithelium and functions as a lubricant. The mucus consists of water, serum, cell macromolecules, somatic cells, microbial cells and glycoprotein. The mucin-glycoprotein structure contains peptide subunits and oligosaccharides bonded to the structure. The subunits consist of single-chain long peptides having the mol.wt. of several hundred thousands dalton. The mucin-glycoprotein has elasticity due to the influence of the oligosaccharides bonded to the mucin-glycoprotein and partially consists of helical molecules which strongly hydrate in an aq. soln.
