A method for enhancing and/or increasing the efficiency of repair of tissues, primarily bone or cartilage, using genetically engineered cells has been developed. In the preferred embodiment, mesenchymal stem cells are isolated from periosteum tissue, and transfected with the gene encoding a growth factor for the particular cell type to be repaired. For example, for repair of bone, a gene (or genes) encoding bone morphogenic protein is transfected into periosteal cells. The transfected periosteal cells then express the bone morphogenic protein in culture to promote bone repair as a function of the expressed bone morphogenic protein. Cells can be transfected using any appropriate means, including viral vectors, as shown by the example, chemical transfectants, or physico-mechanical methods such as electroporation and direct diffusion of DNA. Genes can encode any useful protein, for example, a specific growth factor, morphogenesis factor, a structural protein, or a cytokine which enhances the temporal sequence of wound repair, alters the rate of proliferation, increases the metabolic synthesis of extracellular matrix proteins, or directs phenotypic expression in endogenous cell populations. Representative genes encoding proteins include bone growth factor genes, cartilage growth factor genes, nerve growth factor genes, and general growth factors important in wound healing, such as platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF-1), epidermal growth factor (EGF), basic fibroblast growth factor (FGF), endothelial derived growth supplement.

The clinical practice at Vanderbilt University Medical Center will first perform the routine upper endoscopic exam with a forward-viewing gastroscope to evaluate the patient's esophagus, stomach, and duodenum. After this has been completed, the forward-viewing endoscope will be removed from the patient and outfitted with the EndoTheia NuView. The endoscope with NuView will then be inserted transorally down the esophagus, traverse the stomach, and be passed into the duodenum for visualization of the papilla. After the papilla is visualized, the endoscope with NuView will be removed from the patient. As per standard of care, the conventional side-viewing endoscope will then be inserted transorally down the esophagus, traverse the stomach, and be passed into the duodenum for visualization of the papilla. The side-viewing endoscope will then be removed from the patient. The Investigators plan to enroll 3 FAP patients who are already scheduled to undergo their standard of care endoscopic exam. The primary endpoint of the study is successful visualization of the papilla with the NuView platform.
Compositions and methods for improving cardiac function, myocardial contractility and relaxation in a mammal are provided. Cardiomyocytes transfected with one or more expression vectors comprising a ribonucleotide reductase subunit Rl -encoding nucleic acid sequence and a ribonucleotide reductase subunit R2-encoding nucleic acid sequence operably linked to a promoter are grafted to a mammalian myocardium. Alternatively, viral vector(s) having the Rl and R2-encoding construct(s) are administered to the mammal directly. Overexpression of Rl and R2 subunits leads to formation of the RR complex, which in turn generates dATP. Improvement of cardiac function can also be effected by administration of vectors comprising a nucleic acid sequence encoding a L48Q-substituted, I61Q-substituted, or L57Q-substituted cTnC variant. Also provided are compositions and methods for delivering dATP to a myocardium through grafting of donor cells overexpressing Rl and R2. dATP is thereby produced in situ and delivered through gap junctions established between donor cells and host cardiomyocytes.

Esophageal variceal bleeding represents the most vital complication among patients with liver cirrhosis at rate of 5-15% per year. Endoscopic variceal ligation (EVL), either used as therapeutic in emergency or as prophylactic, is one of the best modalities used in EV treatment. The procedure is effective and generally safe. After banding, a superficial ulcer is formed, which usually heals in 2-3 weeks. The main complications of variceal banding are pain, dysphagia, fever, bleeding during the procedure and post banding ulcer bleeding (PBUB). The prevalence of PBUB is reported to be 3.6-15% . Rebleeding can be fatal, and is mainly resulted from early spontaneous slippage of the rubber bands, before occlusion of the varix with a mature thrombus, leaving an unhealed ulcer . The time frame of variceal rebleeding can be divided into very early rebleeding (within 5 days of acute bleeding), early rebleeding (within 6 weeks of acute bleeding), and delayed rebleeding. Previous reports showed that early rebleeding ranged from 30% to 40% within the first 6 weeks, and was significantly associated with the risk of death within 6 weeks. Therefore, the aim of this research is assessment of incidence , risk factors and prognosis of post-banding ulcer bleeding following EVL in patients with liver cirrhosis, in order to minimize post-banding ulcer bleeding.
AIMS: Diseased atria are characterized by functional and structural heterogeneities, adding to abnormal impulse generation and propagation. These heterogeneities are thought to lie at the origin of fractionated electrograms recorded during sinus rhythm (SR) in atrial fibrillation (AF) patients and are assumed to be involved in the onset and perpetuation (e.g. by re-entry) of this disorder. The underlying mechanisms, however, remain incompletely understood. Here, we tested whether regions of dense fibrosis could create an electrically isolated conduction pathway (EICP) in which re-entry could be established via ectopy and local block to become 'trapped'. We also investigated whether this could generate local fractionated electrograms and whether the re-entrant wave could 'escape' and cause a global tachyarrhythmia due to dynamic changes at a connecting isthmus.
METHODS AND RESULTS: To precisely control and explore the geometrical properties of EICPs, we used light-gated depolarizing ion channels and patterned illumination for creating specific non-conducting regions in silico and in vitro. Insight from these studies was used for complementary investigations in virtual human atria with localized fibrosis. We demonstrated that a re-entrant tachyarrhythmia can exist locally within an EICP with SR prevailing in the surrounding tissue and identified conditions under which re-entry could escape from the EICP, thereby converting a local latent arrhythmic source into an active driver with global impact on the heart. In a realistic three-dimensional model of human atria, unipolar epicardial pseudo-electrograms showed fractionation at the site of 'trapped re-entry' in coexistence with regular SR electrograms elsewhere in the atria. Upon escape of the re-entrant wave, acute arrhythmia onset was observed.
CONCLUSIONS: Trapped re-entry as a latent source of arrhythmogenesis can explain the sudden onset of focal arrhythmias, which are able to transgress into AF. Our study might help to improve the effectiveness of ablation of aberrant cardiac electrical signals in clinical practice.
The invention discloses a traditional Chinese medicinal preparation for treating pediatric epilepsy in the attack stage. Pediatric epilepsy is called as 'epilepsy' in traditional Chinese medical literature and attacks brain, heart, liver, spleen and kidney, the pathogenesis characteristics are evil excess and healthy energy deficiency, and phlegm is the key of pathology. The pediatric epilepsy in the attack stage is caused by phlegm due to spleen deficiency and anemophlegmatic orifice accumulation. The traditional Chinese medicinal preparation is prepared from the following traditional Chinese medicinal materials with effects of eliminating phlegm for resuscitation, clearing heat and arresting epilepsy: hyacinth dolichos stem, calamus, fructus gleditsiae, lycianthes biflora, lespedeza formosa root, ajuga decumbens thunb, ternate grape fern herb, white quartz, cladonia fallax abbayes and gigantism rhodobryum herb. Clinical tests on 55 affected infants indicate that the total effective rate of the traditional Chinese medicinal preparation is 98.2 percent, and the traditional Chinese medicinal preparation has a remarkable curative effect and low treatment cost. The preparation method is simple and convenient.
Congenital heart disease (CHD) is defined as congenital functional or anatomical abnormalities of the heart and intrathoracic great vessels. These abnormalities cover a wide range from minimal defects to serious cardiovascular problems. The prevalence of CHD has been reported as one case per 100 live births, with increases in recent years. As a result of surgical and medical advances in recent years, childhood lethal abnormalities in previous years can be significantly alleviated and repaired. As a result of these developments, 90% of patients born with CHD are expected to survive until adulthood, and today the number of adult CHD has exceeded the number of pediatric CHD. The aging CHD population is at risk of cardiovascular disease in addition to chronic problems resulting from congenital abnormalities. Frailty was defined by the Cardiovascular Health Study Collaborative Research Group as a complex clinical syndrome resulting from cumulative declines in more than one physiological system, leading to reduced resistance to risk factors. Loss of strength, decreased physical activity, involuntary weight loss, decreased mobility, and fatigue are sub-parameters of frailty. Frailty causes common pathophysiological mechanisms with risk factors that play a role in the development of cardiovascular disease. Frailty is associated with a higher incidence of cardiovascular disease and risks of all-cause mortality, leading to a reduction in life expectancy. Cardiorespiratory fitness and functional strength are shown to be the strongest predictors of frailty level and the potential for frailty to decrease over time. It has been reported that frailty worsens cognition and activities of daily living in cardiovascular diseases. There is no study in the literature that comprehensively evaluates vulnerability in individuals with CHD. The aim of this study; To assess frailty in individuals with CHD, to compare functional capacity, muscle strength, activities of daily living, and cognition in individuals with and without CHD. This study, which is planned to be carried out, will enable people with CHD to present a holistic perspective when planning rehabilitation programs and to create a common language for all health professionals.

BACKGROUND: The physiological relevance of cell-to-cell communication mediated by small extracellular vesicle-encapsulated microRNAs (sEV-miRNAs) remains debated because of the limiting representativity of specific miRNAs within the extracellular pool. We hypothesize that sEV-miRNA non-canonical function consisting of the stimulation of Toll-like receptor 7 (TLR7) may rely on a global shift of the sEV cargo rather than on the induction of one or few specific miRNAs. Psoriasis represents an ideal model to test such hypothesis as it is driven by overt activation of TLR7-expressing plasmacytoid dendritic cells (pDCs) following keratinocyte damage.
METHODS: To mimic the onset of psoriasis, keratinocytes were treated with a cocktail of psoriatic cytokines or UV-irradiated. SmallRNA sequencing was performed on sEVs released by healthy and UV-treated keratinocytes. sEV-miRNAs were analyzed for nucleotide composition as well as for the presence of putative TLR7-binding triplets. Primary human pDCs where stimulated with sEVs +/- inhibitors of TLR7 (Enpatoran), of sEV release (GW4869 + manumycin) and of TLR7-mediated pDC activation (anti-BDCA-2 antibody). Secretion of type I IFNs and activation of CD8+T cells were used as readouts. qPCR on psoriatic and healthy skin biopsies was conducted to identify induced miRNAs.
RESULTS: sEV-miRNAs released by damaged keratinocytes revealed a significantly higher content of TLR7-activating sequences than healthy cells. As expected, differential expression analysis confirmed the presence of miRNAs upregulated in psoriatic skin, including miR203a. More importantly, 76.5% of induced miRNAs possessed TLR7-binding features and among these we could detect several previously demonstrated TLR7 ligands. In accordance with this in silico analysis, sEVs from damaged keratinocytes recapitulated key events of psoriatic pathogenesis by triggering pDCs to release type I interferon and activate cytotoxic CD8+T cells in a TLR7- and sEV-dependent manner.
DISCUSSION: Our results demonstrate that miR203a is just one paradigmatic TLR7-activating miRNA among the hundreds released by UV-irradiated keratinocytes, which altogether trigger pDC activation in psoriatic conditions. This represents the first evidence that cell damage shifts the miRNA content of sEVs towards a TLR7-activating cargo capable to propagate inflammation and immunity, offering strong support to the physiological role of systemic miRNA-based cell-to-cell communication.
The normal aging has a devastating effect on our cognitive ability to learn and remember, on the speed with which the investigators process information, and on our ability to reason. By 2050, nearly 14 million individuals in the US will be living with Alzheimer's disease (AD), up from 5 million in 2013. AD is the most common cause of dementia, resulting in the loss of cognitive functions such as memory, reasoning, language, and cognitive, social, physical, and emotional control, to the extent that losses interfere with activities of daily living and necessitate continuous monitoring and care. Many studies now show that the processing machinery of the brain is plastic and remodeled throughout life by learning and experience, enabling the strengthening of cognitive skills or abilities. Research has shown that brief, daily computerized cognitive training that is sufficiently challenging, goal-directed and adaptive enables intact brain structures to restore balance in attention and compensate for disruptions in cognitive functioning. The study aims to understand how our computer program can affect cognition and attention in those with aging brain.
Exocyst component of 70-kDa (EXO70) proteins are constituents of the exocyst complex implicated in vesicle tethering during exocytosis. MILDEW RESISTANCE LOCUS O (MLO) proteins are plant-specific calcium channels and some MLO isoforms enable fungal powdery mildew pathogenesis. We here detected an unexpected phenotypic overlap of Arabidopsis thaliana exo70H4 and mlo2 mlo6 mlo12 triple mutant plants regarding the biogenesis of leaf trichome secondary cell walls. Biochemical and Fourier transform infrared spectroscopic analyses corroborated deficiencies in the composition of trichome cell walls in these mutants. Transgenic lines expressing fluorophore-tagged EXO70H4 and MLO exhibited extensive colocalization of these proteins. Furthermore, mCherry-EXO70H4 mislocalized in trichomes of the mlo triple mutant and, vice versa, MLO6-GFP mislocalized in trichomes of the exo70H4 mutant. Expression of GFP-marked PMR4 callose synthase, a known cargo of EXO70H4-dependent exocytosis, revealed reduced cell wall delivery of GFP-PMR4 in trichomes of mlo triple mutant plants. In vivo protein-protein interaction assays in plant and yeast cells uncovered isoform-preferential interactions between EXO70.2 subfamily members and MLO proteins. Finally, exo70H4 and mlo6 mutants, when combined, showed synergistically enhanced resistance to powdery mildew attack. Taken together, our data point to an isoform-specific interplay of EXO70 and MLO proteins in the modulation of trichome cell wall biogenesis and powdery mildew susceptibility.
INTRODUCTION: Benefits and harms of avoid the sent placement during IntraCorporeal Neobladder configuration are still debated. Our objective was to describe the step-by-step technique of Florence intracorporeal neobladder (FloRIN) configuration performed with stentless procedure focusing on perioperative and mid-term functional outcomes.
MATERIALS AND METHODS: In this single institution prospective randomized 1:1 series all consecutive patients underwent Robot-Assisted Radical Cystectomy (RARC) and FloRIN reconfiguration from January 2021 to March 2021 were enrolled. Functional perioperative and mid-term outcomes were gathered. Postoperative complications were graded according to Clavien-Dindo classification and divided in early (<30 days from discharge) and delayed (>30 days).
RESULTS: Overall, 10 patients were included in the analysis. Of these, the 50.0% was treated with Stentless FloRIN. In terms of baseline features, no differences were recorded between the two groups. Median age was 65 and 66 years while median BMI was 27 and 25 in the stentless and in the stent group, respectively. Concerning intraoperative variables, no intraoperative complications as well as open conversion occurred among both groups. As regard introperative features, a shorter console time was associated with stentless procedure (331 min vs 365 min). In terms of perioperative outcomes, canalization and time to drainage removal didn't differ between groups while length of hospital stay was significantly lower in stentless group 10 days versus 14 days. Early and delayed postoperative complication rate was not influenced by the ureteral management at a preliminary assessment with comparable rates of Clavien Dindo ⩾ 3a between the two groups. Mid-term functional outcomes did not differ between groups in terms of kidney function loss.
CONCLUSIONS: FloRIN with Stentless technique showed functional and perioperative preliminary outcomes comparable with the standard ureteral management strategy. Further series with longer functional follow-up assessment will be needed to confirm our preliminary results.

Disseminated infection with Mycobacteria avium complex (MAC) is one of the most common systemic bacterial infections in advanced stages of the acquired immunodeficiency syndrome (AIDS). Current therapy for disseminated MAC infection in HIV patients consists of multidrug chemotherapy regimens are often accompanied by toxicities, and many patients become intolerant of one or more agents. Macrolides are the essential component of successful therapy, yet macrolide resistant strains are being recognized with increasing frequency. Thus, there is an interest in identifying additional therapeutic interventions for disseminated MAC in HIV-infected patients. Interleukin-12 (IL-12) is a central, regulatory cytokine in cell-mediated immunity. IL-12 enhances the cytolytic activity of cytotoxic T and NK cells, and induces interferon-gamma (IFN gamma) production from T and NK cells. This open-label Phase I study is designed to evaluate the safety and immunologic/microbiologic effects of interleukin-12 administration in HIV-infected patients with concomitant disseminated Mycobacterium avium (MAC) infection or localized MAC infection. Fifteen patients with documented disseminated MAC will be randomized to receive double-blinded placebo or escalating doses of IL-12 in addition to anti-MAC chemotherapy and standard anti-retroviral therapy for six weeks. IL-12 will be administered subcutaneously, with escalating doses every month over the dose range of 30 ng/kg, 100 ng/kg, and 300 ng/kg, or until an individual maximum tolerated dose (IMTD) is reached. Should a patient receive 2 consecutive blood cultures negative for MAC during the course of the study at a lower dose, then he/she will not be further dose escalated. Likewise, patients with localized disease will not be further dose escalated if symptoms/evidence of localized infection resolve as assessed by the principal investigator. Those patients receiving placebo after 6 weeks will be crossed over to receive the full treatment course of IL-12. Each new dose or dose escalation will take place on an inpatient basis. Once a patient is clinically stable at a dose, the patient will be maintained at that dose as an outpatient for the remainder of the month. Total IL-12 administration will not exceed 12 weeks, or 24 total doses.
