Participants allocated into this arm will undergo a baseline cardiac MRI. Then a single dose of midazolam (2 mg intravenously) will be given to each participant in this arm. After 5 minutes of midazolam administration a control cardiac MRI will be performed to detect changes in heart function following sedation administration.
While advances in medical care have reduced mortality rates across the globe, the same cannot be said for perinatal mortality. This is particularly true of Low and Middle Income Countries (LMICs), which contribute by far the largest proportion of the estimated 5.4 million perinatal deaths annually. Key reasons for this include lack of systematic screening, lack of early health advice-seeking, lack of training for the healthcare workers involved in the healthcare delivery chain and a lack of robust referral. To address these issues, the investigators will introduce and evaluate a scalable mobile health (mHealth) referral system in Guatemala, one of the poorest countries in Latin America with one of the highest perinatal mortality rates. The system combines several key innovations which have been developed over the last 10 years. First, the investigators will introduce a low cost (under $30) ultrasound screening tool, with a blood pressure cuff and pulse oximeter, from which data is fed directly to a smartphone to produce an on-the-spot assessment of the health of the fetus and mother, using a step-by-step pictorial guide (also on the phone). Second, the investigators will implement a mobile phone-mediated medical record and referral system that allows users of both smartphones and basic mobile phones to upload data into a standardized medical record system already in operation in Guatemala. The data will allow healthcare workers to identify or enroll patients, review their histories, and schedule future screenings or follow-up visits, as well as equip the healthcare providers with the necessary information to assess needs, resource allocation and efficacy of treatment or personnel. Thirdly, the investigators will introduce a training protocol for lay midwives to provide routine screening with the system for risk factors such as high blood pressure, fetal growth restriction and fetal distress, and to promote postnatal care coordination. Importantly, this shared system will facilitate communication between the obstetrical care team and the postnatal child care team, which currently represents one of the most pressing care coordination challenges in rural Guatemala. By bringing together engineers, physicians, public health workers, anthropologists, and local nongovernmental organizations to co-design the system around the needs of the existing healthcare infrastructure and the local population, the investigators will create an intuitive system which relieves the burden of data collection, improves diagnostic capabilities, and assists with rapid and accurate referral. The system will also facilitate inter-facility research by introducing a standard medical record protocol.
PURPOSE: Commercial double J stents (DJS) have a uniform shape regardless of the specific nature of various ureteral diseases. We tested renovated DJS and compared them with conventional DJS using ureter models.
METHODS: One straight ureter model included stenosis at the distal ureter near the ureterovesical junction and the other did not. We used conventional DJS and renovated 5- and 6-Fr soft DJS for ureter stones and 6-, 7-, and 8.5-Fr hard DJS for tumors. The DJS comprised holes in the upper, middle, or lower one-third of the shaft (length, 24 cm; 2-cm-diameter coils at both ends). More holes were created along the shaft based on the ureteral disease location. Conventional DJS had holes spaced 1 cm apart along the shaft. Renovated DJS had holes spaced 1 cm apart along the shaft with 0.5-cm intervals on the upper, middle, or lower one-third of the shaft. Urine flow was evaluated.
RESULTS: As the DJS diameter increased, the flow rate decreased. The flow rates of DJS with holes in the lower shaft were relatively lower than those of conventional DJS and DJS with holes in the upper and middle shafts. In the ureter model without stenosis, 6-, 7-, and 8.5-Fr renovated stents exhibited significantly higher flow rates than conventional stents. In the ureter model with stenosis, 5-, 6-, 7-, and 8.5-Fr renovated stents did not exhibit significantly higher flow rates than conventional stents.
CONCLUSION: Renovated stents and conventional stents did not exhibit significant differences in urine flow with stenosis.

Many animal species do not breathe in a continuous, rhythmic fashion, but rather display a variety of breathing patterns characterized by prolonged periods between breaths (inter-breath intervals), during which the heart continues to beat. Examples of intermittent breathing abound across the animal kingdom, from crustaceans to cetaceans. With respect to human physiology, intermittent breathing-also termed 'periodic' or 'episodic' breathing-is associated with a variety of pathologies. Cardiovascular phenomena associated with intermittent breathing in diving species have been termed 'diving bradycardia', 'submersion bradycardia', 'immersion bradycardia', 'ventilation tachycardia', 'respiratory sinus arrhythmia' and so forth. An examination across the literature of terminology applied to these physiological phenomena indicates, unfortunately, no attempt at standardization. This might be viewed as an esoteric semantic problem except for the fact that many of the terms variously used by different authors carry with them implicit or explicit suggestions of underlying physiological mechanisms and even human-associated pathologies. In this article, we review several phenomena associated with diving and intermittent breathing, indicate the semantic issues arising from the use of each term, and make recommendations for best practice when applying specific terms to particular cardiorespiratory patterns. Ultimately, we emphasize that the biology-not the semantics-is what is important, but also stress that confusion surrounding underlying mechanisms can be avoided by more careful attention to terms describing physiological changes during intermittent breathing and diving.

Chronic kidney disease (CKD) development after acute kidney injury (AKI) involves multiple mechanisms, including inflammation, epithelial-mesenchymal transition (EMT), and extracellular matrix deposition, leading to progressive tubulointerstitial fibrosis. Recently, a central role for peroxisome-proliferator activated receptor (PPAR)-α has been addressed in preserving kidney function during AKI. Among endogenous lipid mediators, oleoylethanolamide (OEA), a PPAR-α agonist, has been studied for its metabolic and anti-inflammatory effects. Here, we have investigated OEA effects on folic acid (FA)-induced kidney injury in mice and the underlying mechanisms. OEA improved kidney function, normalized urine output, and reduced serum BUN, creatinine, and albuminuria. Moreover, OEA attenuated tubular epithelial injury, as shown by histological analysis, and decreased expression of neutrophil gelatinase-associated lipocalin and kidney injury molecule-1. Gene expression analysis of kidney tissue indicated that OEA limited immune cell infiltration and inflammation. Moreover, OEA significantly inhibited Wnt7b and Catnb1 gene transcription and α-smooth muscle actin expression, indicating suppression of EMT. Accordingly, OEA exhibited an anti-fibrotic effect, as shown by Masson staining and the reduced levels of transforming growth factor (TGF)-β1, fibronectin, and collagen IV. Mechanistically, the nephroprotective effect of OEA was related to PPAR-α activation since OEA failed to exert its beneficial activity in FA-insulted PPAR-α-/- mice. PPAR-α involvement was also confirmed in HK2 cells where GW6471, a PPAR-α antagonist, blunted OEA activity on the TGF-β1 signalling pathway and associated pro-inflammatory and fibrotic patterns. Our findings revealed that OEA counteracts kidney injury by controlling inflammation and fibrosis, making it an effective therapeutic tool for limiting AKI to CKD progression.
The invention is concerned with a kind of sustained and controlled release injection of vanticancer compound of depressor with protein tyrosine kinase and /or alkylating agent, relating to sustained and controlled release microsphere and menstruum. The microsphere has effect component and sustained and controlled release assistant stuff form the depressor with protein tyrosine kinase and/ or alkylating agent, and the menstruum is common menstruum or special menstruum with assistant suspending agent. The viscosity of assistant suspending agent is 100cp to 3000cp (20 to 30 degree) selecting form Carboxymethylcellulose sodium, and so on. The sustained and controlled release assistant stuff are seleted from the polyphosphate ester copolymer or copolymer of polyphosphate ester and polylactic acid, polystyrene propionic double fatty acids and sebacic acid, copolymer of poly (erucic acid dimmer-sebacic acid) or poly (fumaric acid-sebacic acid), such as p(LAEG-EOP), p(DAPG-EOP), p(BHET-EOP/TC), p( BHET-EOP/TC), p(BHDPT-EOP/TC), p(BHDPT-EOP/TC), p(CHDM-HOP) or p(CHDM-EOP). The anticancer compound is made into sustained and controlled release implant and injects or sets in the tumour or on the round of tumour to maintain the effect concentration over 60 days. It reduces the reaction of whole body greatly and increases the cure effect of nonoperative treatments, such as chemoradiotherapy with selectivity.
A major goal of healthy aging is to prevent declining resilience and increasing frailty, which are associated with many chronic diseases and deterioration of stress response. Here, we propose a loss-or-gain survival model, represented by the ratio of cumulative stress span to life span, to quantify stress resilience at organismal level. As a proof of concept, this is demonstrated by reduced survival resilience in Caenorhabditis elegans exposed to exogenous oxidative stress induced by paraquat or with endogenous proteotoxic stress caused by polyglutamine or amyloid-β aggregation. Based on this, we reveal that a hidden peptide ("cryptide")-AbaPep#07 (SETYELRK)-derived from abalone hemocyanin not only enhances survival resilience against paraquat-induced oxidative stress but also rescues proteotoxicity-mediated behavioral deficits in C. elegans, indicating its capacity against stress and neurodegeneration. Interestingly, AbaPep#07 is also found to increase cost-free longevity and age-related physical fitness in nematodes. We then demonstrate that AbaPep#07 can promote nuclear localization of SKN-1/Nrf, but not DAF-16/FOXO, transcription factor. In contrast to its effects in wild-type nematodes, AbaPep#07 cannot increase oxidative stress survival and physical motility in loss-of-function skn-1 mutant, suggesting an SKN-1/Nrf-dependent fashion of these effects. Further investigation reveals that AbaPep#07 can induce transcriptional activation of immune defense, lipid metabolism, and metabolic detoxification pathways, including many SKN-1/Nrf target genes. Together, our findings demonstrate that AbaPep#07 is able to boost stress resilience and reduce behavioral frailty via SKN-1/Nrf-governed transcriptional reprogramming, and provide an insight into the health-promoting potential of antioxidant cryptides as geroprotectors in aging and associated conditions.

The present study examined whether people higher in psychopathy experienced less self-reported and psychophysiological nociceptive pressure than people lower in psychopathy. We also examined whether psychopathy affects empathy for others' pain via self-reported and psychophysiological measures. Three hundred and sixty-nine students (18-78 years; M = 26, SD = 9.34) were screened for psychopathic traits using the Youth Psychopathy Inventory (YPI). Stratified sampling was used to recruit 49 adults residing in the highest (n = 23) and lowest (n = 26) 20% of the psychopathy spectrum. Using skin conductance response (SCR) and self-report responses, participants responded to individually adjusted intensities of pneumatic pressure and others' pain images and completed self-reported psychopathy and empathy measures (Triarchic Psychopathy Measure, TriPm; Interpersonal Reactivity Index, IRI). People higher in psychopathy self-reported feeling less nociceptive pressure compared to people lower in psychopathy, yet we did not find any differences in SCR to nociceptive pressure. However, when viewing other people in pain, the high psychopathy group displayed lower SCR and lower self-reported empathy compared to those lower in psychopathy. Our results suggest psychopathic traits relate to problems empathising with others' pain, as well as the perception of nociceptive pressure. We also show support for the theory of dual harm which has been receiving increasing attention. Consequently, psychopathy interventions should focus both on recognising and empathising with the pain of others.
The present disclosure is directed to a new technique for MR measurement of ultrashort T2* relaxation utilizing spin-echo acquisition. The ultrashort T2* relaxometry can be used for the quantification of highly concentrated iron labeled cells in cell trafficking and therapy. In an exemplary embodiment, a signal is induced by a low flip angle RF pulse. Following excitation pulse, a gradient readout is applied to form an echo. The time between the RF pulse and the center of the gradient readout is defined as TE. In tissues with highly concentrated iron labeled cells, T2* could be below 1 millisecond. Therefore, the signal can be decayed to a noise level with an echo time of a couple milliseconds. Because T2* is much longer in SPIO labeled cells, the signal acquired by spin echo is much bigger than that from the gradient echo, thus avoiding the negative effects associated with the massive signal loss in the image. The ultrashort T2* relaxation map can then by overlaid on the regular T2* map to generate the final T2* map of the field of view.
This invention relates to cell differentiation agent-II (CDA-II) purified from fresh human urine. This preparation is effective for the therapy and prevention of cancer. A common feature of cancer is that all cancer cells keep on dividing, and are unable to undergo terminal differentiation. Abnormal methylation enzymes are a major factor contributing to this unique feature. CDA-II is effective to convert abnormal methylation enzymes into normal enzymes, thus enabling cancer cells to undergo terminal differentiation. This is a novel approach for cancer therepy designed to eliminate the cause of the disease. Since the terget is a cancer specific protein factor associated with methylation enzymes, the therapy is selective and without adverse side effects. Active components of CDA-II consist of differentiation inducers, helper inducers, and anticachexia agents. All these are essential to achieve therapentic efficacy. In addition, we have discovered that CDA-II employed in conjunction with thymidine produced much better anticancer effect. The synergistic anticancer effect is indeed remarkable.
This study is a multi-center phase 2 study of carfilzomib, lenalidomide, daratumumab, and dexamethasone in subjects with high-risk smoldering multiple myeloma (SMM). Myeloma remains incurable with the current approaches. The typical natural history of myeloma is one of repeated relapses, accompanied by genetic evolution and development of new abnormalities, which are often responsible for drug resistance. The presence of a precursor phase of smoldering myeloma, and the ability to identify those at the highest risk of progression, sets the stage to examine the possibility that we can cure the disease through early intervention. In order to potentially achieve this, we need to develop a highly effective combination that includes the most active drugs from different classes. Carfilzomib in combination with lenalidomide and dexamethasone results in high response rates and deep responses in subjects with newly diagnosed myeloma. Daratumumab in combination with lenalidomide results in high response rates in relapsed refractory disease. All these drugs are well tolerated and subjects are able to stay on them long term as a maintenance treatment. The combination of the carfilzomib, lenalidomide, daratumumab and dexamethasone presents the potential to enhance the effectiveness of the regimens. We hypothesize that this combination will lead to deep response including a higher proportion of minimal residual disease (MRD) negative disease among those with high risk smoldering myeloma and may translate into cure or long term disease quiescence.

Heme oxygenase 1 is a key enzyme in the management of heme in humans. A GT(n) repeat length in the heme oxygenase 1 gene (HMOX1) has been widely associated with a variety of phenotypes, including susceptibility to and outcomes in diabetes, cancer, infections, and neonatal jaundice. However, studies have generally been small and results inconsistent. In this study, we imputed the GT(n) repeat length in participants from 2 UK cohort studies (the UK Biobank study (n = 463,005; recruited in 2006-2010) and the Avon Longitudinal Study of Parents and Children (ALSPAC; n = 937; recruited in 1990-1991)), with the reliability of imputation tested in other cohorts (1000 Genomes Project, Human Genome Diversity Project, and Personal Genome Project UK). Subsequently, we measured the relationship between repeat length and previously identified associations (diabetes, chronic obstructive pulmonary disease, pneumonia, and infection-related mortality in the UK Biobank; neonatal jaundice in ALSPAC) and performed a phenomewide association study in the UK Biobank. Despite high-quality imputation (correlation between true repeat length and imputed repeat length > 0.9 in test cohorts), clinical associations were not identified in either the phenomewide association study or specific association studies. These findings were robust to definitions of repeat length and sensitivity analyses. Despite multiple smaller studies identifying associations across a variety of clinical settings, we could not replicate or identify any relevant phenotypic associations with the HMOX1 GT(n) repeat.
OBJECTIVE: The purpose of this study was to investigate the role and possible mechanism of lncRNA XIST in renal fibrosis and to provide potential endogenous targets for renal fibrosis in obstructive nephropathy (ON).
METHODS: The study included 50 cases of ON with renal fibrosis (samples taken from patients undergoing nephrectomy due to ON) and 50 cases of normal renal tissue (samples taken from patients undergoing total or partial nephrectomy due to accidental injury, congenital malformations, and benign tumors). Treatment of human proximal renal tubular epithelium (HK-2) cells with TGF-β1 simulated renal fibrosis in vitro. Cell viability and proliferation were measured by CCK-8 and EdU, and cell migration was measured by transwell. XIST, miR-124-3p, ITGB1, and epithelial-mesenchymal transition (EMT)-related proteins (E-cadherin, α-SMA, and fibronectin) were detected by PCR and immunoblot. The targeting relationship between miR-124-3p and XIST or ITGB1 was verified by starBase and dual luciferase reporter gene experiments. In addition, The left ureter was ligated in mice as a model of unilateral ureteral obstruction (UUO), and the renal histopathology was observed by HE staining and Masson staining.
RESULTS: ON patients with renal fibrosis had elevated XIST and ITGB1 levels and reduced miR-124-3p levels. The administration of TGF-β1 exhibited a dose-dependent promotion of HK-2 cell viability, proliferation, migration, and EMT. Conversely, depleting XIST or enhancing miR-124-3p hindered HK-2 cell viability, proliferation, migration, and EMT in TGF-β1-damaged HK-2 cells HK-2 cells. XIST functioned as a miR-124-3p sponge. Additionally, miR-124-3p negatively regulated ITGB1 expression. Elevating ITGB1 weakened the impact of XIST depletion on TGF-β1-damaged HK-2 cells. Down-regulating XIST improved renal fibrosis in UUO mice.
CONCLUSION: XIST promotes renal fibrosis in ON by elevating miR-124-3p and reducing ITGB1 expressions.
