INTRODUCTION: A freeze-dried, platelet-derived hemostatic agent (FPH) was developed for acute hemorrhage. The canine product (cFPH) was developed for use in preclinical models supporting human product (hFPH) investigations.
MATERIALS AND METHODS: A carotid artery bypass graft (CABG) study in dogs compared 3 dosages of cFPH to canine liquid stored platelets (cLSP) and vehicle (VEH) control groups. Histopathological analysis and blood loss assessments were completed. A separate ex-vivo synthetic graft study assessed thrombogenicity via blood from human and canine donors that was combined with species-specific FPH or apheresis platelets. Characterization of cFPH and hFPH included thrombin generation, total thrombus formation, and scanning electron microscopy.
RESULTS: Blood loss was reduced in CABG dogs receiving standard of care (cLSP) or cFPH treatment compared to VEH control; a cFPH dose effect signal was observed. Further, cFPH dosing up to 5 × 109 cells/kg was not associated with increased mortality or occlusion of the anastomosis sites, and histopathologic evidence of off-target thrombosis was not detected. When passed through a synthetic graft (ex vivo), whole blood combined with species-specific FPH did not result in thrombosis beyond that of whole blood control. In vitro testing and imaging of cFPH and FPH were comparable.
CONCLUSIONS: A single dose of cFPH or cLSP reduced blood loss in a pilot surgical study and was well tolerated with no related adverse events. Further, the hemostatic activity and characteristics of cFPH are comparable to that of hFPH, suggesting that research findings from the canine product are likely to inform the development of the human product.
Zirconium-based metal-organic frameworks (UiO-66) have gained considerable attention owing to their versatile application. In the present research, UiO-66 was synthesized via a defect engineering approach, and its toxicity profile was explored. The synthesized nanomaterial was extensively characterized via spectroscopic methods such as FTIR and Raman spectroscopy, which confirmed the formation of the framework. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to determine the crystallinity, shape and size of the nanoformulations. Thermal gravimetric analysis, 1H NMR spectroscopy and Brunauer-Emmett-Teller (BET) surface area analysis were used to identify the differences between pristine and defective UiO-66. Furthermore, the synthesized MOF was exposed to various pH conditions, serum protein and DMEM. Drug loading and release studies were evaluated using 5-fluorouracil as a model anticancer drug. The synthesized MOFs were modified with hyaluronic acid via mussel-inspired polymerization to increase their uptake and stability. More importantly, the toxicity of the nanoformulation was investigated via various toxicity studies, such as hemolysis assays and cell viability assays, and was further supported by in vivo acute and subacute toxicity data obtained from Wistar rats. Radiolabelling and bio-distribution studies were also performed using 177Lu to explore the bio-distribution profile of UiO-66.
Chronic primary pain conditions (CPPCs) affect over 100 million Americans, predominantly women. They remain ineffectively treated, in large part because of a lack of valid animal models with translational relevance. Here, we characterized a CPPC mouse model that integrated clinically relevant genetic (catechol-O-methyltransferase; COMT knockdown) and environmental (stress and injury) factors. Compared with wild-type mice, Comt+/- mice undergoing repeated swim stress and molar extraction surgery intervention exhibited pronounced multisite body pain and depressive-like behavior lasting >3 months. Comt+/- mice undergoing the intervention also exhibited enhanced activity of primary afferent nociceptors innervating hindpaw and low back sites and increased plasma concentrations of norepinephrine and pro-inflammatory cytokines interleukin-6 (IL-6) and IL-17A. The pain and depressive-like behavior were of greater magnitude and longer duration (≥12 months) in females versus males. Furthermore, increases in anxiety-like behavior and IL-6 were female-specific. The effect of COMT genotype × stress interactions on pain, IL-6, and IL-17A was validated in a cohort of 549 patients with CPPCs, demonstrating clinical relevance. Last, we assessed the predictive validity of the model for analgesic screening and found that it successfully predicted the lack of efficacy of minocycline and the CB2 agonist GW842166X, which were effective in spared nerve injury and complete Freund's adjuvant models, respectively, but failed in clinical trials. Yet, pain in the CPPC model was alleviated by the beta-3 adrenergic antagonist SR59230A. Thus, the CPPC mouse model reliably recapitulates clinically and biologically relevant features of CPPCs and may be implemented to test underlying mechanisms and find new therapeutics.
Changes in the respiratory muscles play an important role in the pathophysiology of exercise intolerance in CHF patients. The weakness of the respiratory muscles leads to a decrease in the efficiency of breathing and the formation of a pathological type of breathing, in which the inhalation time is prolonged, and the expiration time is shortened. Patients with weak respiratory muscles have impaired functional status, as determined by peak oxygen consumption. The violation of the ratio of inspiratory time / to the total time of the respiratory cycle is associated with an increase in the activity of the sympathoadrenal system. The positive effect of respiratory muscle training on MIP, MEP, peak VО 2, VE, VE / VCO 2 slope, VE oscillation, rhythm variability, and quality of life parameters is shown. Decreased oxygenation of the respiratory muscles during intense physical exertion in patients with CHF may increase respiratory failure and provoke hyperactivation of the inspiratory metaboreflex, thereby aggravating exercise intolerance due to a decrease in muscular-muscular system perfusion due to redistribution of blood flow. In addition, it was shown that fatigue of the respiratory muscles increases the activity of the sympathetic nervous system and reduces blood flow in the muscles of the inactive limb due to adrenergic vasoconstriction. This response is most likely associated with metabolic stimulation of small afferent type III and IV fibers of the respiratory muscles, especially the diaphragm. Respiratory muscle training can minimize the effects of inspiration metaboreflex activation and prolong the duration of exercise. In addition, several studies have shown that the strength of the respiratory muscles in patients with HF correlates with central hemodynamic indices at rest, including cardiac output, mean pulmonary pressure and pulmonary vascular resistance. Several studies have shown that the mechanism that improves exercise tolerance in patients with HF after training the respiratory muscles is to increase the blood supply to the muscles of the limbs at rest and during exercise. Thus, the mechanisms of the effect of the weakness of the respiratory muscles on the pathogenesis of a decrease in the functional ability of patients are well studied. Both respiratory muscular and aerobic exercises of moderate effectiveness are recommended by leading medical communities as an effective means to improve the functional ability of patients, improve quality of life parameters, improve symptoms and reduce hospital admissions (level of evidence Level 1). At the same time, respiratory muscle training is recommended as the beginning of physical rehabilitation in patients with IV FC HF, and moderate-intensity aerobic training is recommended for patients with FC I-III FC. Also, in individual works abroad, the effects of respiratory muscle training on clinical CHF. However, according to the investigator's information, no studies have been carried out on the study of the method of functional training, including training of the respiratory muscles, as an obligatory initial stage of physical rehabilitation of patients with any functional class of HF.
Shoulder pain is one of the most common complications of stroke. In fact, it occurs up to 70% of stroke victims. Post-stroke shoulder pain impacts negatively on daily activities. Moreover, it interferes with the rehabilitation process, is related to poor quality of life and has been associated to a worse outcome and to prolonged hospitalization.The aetiology of post-stroke HSP is uncertain, although it has been associated with various factors: joint disorders, capsulitis adhesive, subluxation of the head of the humerus, rotator cuff tendons injuries and spasticity of surrounding muscles. Clinicians use a wide variety of approaches to treat post-stroke HSP, although none has yet been proven effective. Correct positioning and careful handling of the hemiplegic limb are believed to prevent HSP. Physiotherapy alone does not seem to be effective for this complication. Capsulitis adhesive can be successfully treated with corticosteroid injections in the shoulder. However, despite many randomized controlled trials of corticosteroid injections for shoulder pain, their effects remain controversial. The large number of interventions and the lack of consensus about their effectiveness suggest that the aetiology is poorly understood and hence its treatment remains to be established. Intramuscular injections of botulinum toxin type A (BT-A) have also been demonstrated to reduce HSP. The mechanism whereby intramuscular inoculation of BT-A reduces pain may include a muscle relaxant effect and inhibition of the release of neurotransmitters by sensory neurons. Nevertheless, this approach has some limitations: it is probably more effective in muscular than in articular pain and it may be influenced by the muscles affected and site of injection. Intra-articular injection of BT-A has recently proven safe and effective in the treatment of refractory joint shoulder pain caused by chronic arthritis. The mechanisms by which it exerts this effect are not known, but could include inhibition of the release of pain peptides from nerve terminals and sensory ganglia, and anti-inflammatory and anti-glutaminergic effects.
Patient-Centred Education : a one-off three-hour workshop of structured group education (4-5 persons in each group) and three 2-weekly phone calls. The aim will be to modify patients' illness beliefs and perceptions about IC/PAD by educating them on disease pathology and management philosophy. After the workshop, each patient will be supported to set goals for walking, develop an action plan regarding how these goals will be met and encouraged to repeat this process for each new walking goal.
PURPOSE: To assess the impact of endoscope-assisted fractured roots or fragments extraction within the mandibular canal, along with quantitative sensory testing (QST) alterations in the inferior alveolar nerve (IAN).
METHODS: Six patients with lower lip numbness following mandibular third molar extraction were selected. All patients had broken roots or fragments within the mandibular canal that were extracted under real-time endoscopic assistance. Follow-up assessments were conducted on postoperative days 1, 7, and 35, including a standardized QST of the lower lip skin.
RESULTS: The average surgical duration was 32.5 min, with the IAN exposed in all cases. Two of the patient exhibited complete recovery of lower lip numbness, three experienced symptom improvement, and one patient remained unaffected 35 days after the surgery. Preoperative QST results showed that the mechanical detection and pain thresholds on the affected side were significantly higher than those on the healthy side, but improved significantly by postoperative day 7 in five patients, and returned to baseline in two patients on day 35. There were no significant differences in the remaining QST parameters.
CONCLUSIONS: All endoscopic surgical procedures were successfully completed without any additional postoperative complications. There were no cases of deterioration of IAN injury, and lower lip numbness recovered in the majority of cases. Endoscopy allowed direct visualization and examination of the affected nerve, facilitating a comprehensive analysis of the IAN.
The invention relates to application of ginkgolic acid in weight losing. The ginkgolic acid comprises ginkgolic acid, ginkgol and bilobol and can be obtained from extracts of such parts of the gingko as leaves, fruits, testae and rootstalks by a chemical separation method. A weight reducing medicament or cosmetic contains 0.001-80% of ginkgolic acid by weight percent and pharmaceutically common external preparation substrates or acceptable carriers. The preparation is any one pharmaceutically called external dosage form. Pharmacological experiment studies show that the preparation has the functions of reducing weight, body fat and adipocyte quantity and volume and has the effect of reducing blood sugar and blood fat. Trial results of fat people show that the preparation has the functions of reducing weight and removing fat, is obvious in weight reducing effect, is safe to use and has no effects.
Folate/choline/betaine, service as a methyl-donor nutrients, are essential nutrients involving in hepatic one-carbon and bioenergetic metabolism. Methyl-donor nutrients deficiency cause liver and muscle dysfunction as result of non-alcoholic fatty liver diseases (NAFLD) and its progressive lesions of steatohepatitis (NASH), fibrinogen cirrhosis and hepatoma. As methyl-donor nutrients intakes in Taiwanese population are highly insufficient, the dietary requirement of methyl-donor nutrients upon genetic, epigenetic and microbiota interaction to prevent or/and co-therapy of NAFLD progression is currently not known. In this study, we investigate whether intervention of methyl-donor nutrients improve or retard NAFLD progress. NAFLD patients are randomly divided into three groups and received placebo, folic acid, or choline, respectively. From first day to ten day, interventions are given double recommended daily intake dose of folic acid or double adequate Intakes dose of choline, then continuing with four times, and eight times dose for every 10 days. All supplements solve in cranberry juice. At the end of every ten days intervention prior, interventions are measurement of weight and body fat, and collection of blood and feces. The primary outcome measures are described to decreased body weight or body fat, improvement of liver function and fatty liver, and increasing methyl-donor nutrients levels.
Previously, our studies have demonstrated the presence of nerve plane in laparoscopic rectal cancer surgery, which was the overlying tiny membranous tissue including the nerves, the adipose tissue, and the extremely tiny capillaries around the nerve. As a consequence, the concept of nerve plane-oriented functional total mesorectal excision (FTME) was proposed as an optimal surgical procedure about pelvic autonomic nerve preservation in rectal cancer surgery. Following the TME principles, the surgical procedure of FTME was guided by the nerve plane and dissected between the proper fascia of the rectum and nerve plane (the first gap), which could ensure completeness of the nerve plane and the proper fascia of the rectum. This surgical procedure not only ensures radical resection but also protects PAN better, and the investigators also showed the difference between routine TME and FTME in our previous study, which included inferior mesenteric plexus preservation, station 253 nodes dissection, existence of the first gap, Waldeyer's fascia and Denonvillier's fascia (DVF) preservation, neurovascular bundles preservation, and completeness of mesorectum and nerve plane. Currently, it was a lack of higher-level evidence-based evidence to confirm the protective effect of laparoscopic FTME on urinary and sexual function in male patients with mid-low rectal cancer. In the present study, the investigators performed the prospective, single-arm, multicenter, uncontrolled clinical study, eligible patients will be performed laparoscopic FTME surgery. Postoperative sexual function, urinary function, complications, quality of life, recurrence rate, recurrence patterns, disease-free survival, and overall survival will be recorded prospectively. The results of the patients will be assessed to validate postoperative functional outcomes and oncologic outcomes of laparoscopic FTME surgery.
Conjugate for targeting therapeutic or diagnostic agent or drug to cells or tissues in a body, e.g. areas of neoplastic growth or angiogenesis. Use of conjugate for in vivo diagnosis or therapy e.g. inhibiting tumour growth or metastasis, inhibiting angiogenesis and/or treating cancer. Conjugate comprises therapeutic or diagnostic agent as oligomeric protein e.g.  heterodimeric protein, wherein first and second subunits of protein are each conjugated to a specific binding member e.g. an antibody fragment such as scFv. Subunits of oligomer may be conjugated to specific binding members as fusion proteins. Conjugate may comprise IL-12 heterodimer having two subunits, each subunit fused to scFv L19 or TN11 for targeting IL-12 to extracellular matrix components associated with neoplastic growth and angiogenesis.

Female smokers interested in quitting in the next 6 months will be referred to an in-person counseling session at the clinic. Participants then receive 4 phone counseling over 15-20 minutes with a trained tobacco treatment specialist.
Hypertrophic cardiomyopathy (HCM) is characterised by asymmetric left ventricular hypertrophy, ventricular arrhythmias, and cardiomyocyte dysfunction that may cause sudden death. HCM is associated with mutations in sarcomeric proteins and is usually transmitted as an autosomal-dominant trait. The aim of this in silico study was to assess the mechanisms that underlie the altered electrophysiological activity, contractility, regulation of energy metabolism, and crossbridge cycling in HCM at the single-cell level. To investigate this, we developed a human ventricular cardiomyocyte model that incorporates electrophysiology, metabolism, and force generation. The model was validated by its ability to reproduce the experimentally observed kinetic properties of human HCM induced by (a) remodelling of several ion channels and Ca2+-handling proteins arising from altered Ca2+/calmodulin kinase II signalling pathways and (b) increased Ca2+ sensitivity of the myofilament proteins. Our simulation showed a decreased phosphocreatine-to-ATP ratio (-9%) suggesting a negative mismatch between energy expenditure and supply. Using a spatial myofilament half-sarcomere model, we also compared the fraction of detached, weakly bound, and strongly bound crossbridges in the control and HCM conditions. Our simulations showed that HCM has more crossbridges in force-producing states than in the control condition. In conclusion, our model reveals that impaired crossbridge kinetics is accompanied by a negative mismatch between the ATP supply and demand ratio. This suggests that improving this ratio may reduce the incidence of sudden death in HCM.
Improving access to kidney transplants remains a priority for the transplant community. However, many medical, psychosocial, geographic, and socioeconomic barriers exist that prevent or delay transplantation for candidates with certain conditions. There is a lack of consensus regarding how to best approach many of these issues and barriers, leading to heterogeneity in transplant centers' management and acceptance practices for a variety of pretransplant candidate issues. In this review, we address several of the more common contemporary patient medical and psychosocial barriers frequently encountered by transplant programs. The barriers discussed here include kidney transplant candidates with obesity, older age, prior malignancy, cardiovascular disease, history of nonadherence, and cannabis use. Improving understanding of how to best address these specific issues can empower referring providers, transplant programs, and patients to address these issues as necessary to progress toward eventual successful transplantation.
Cerebral palsy (CP) describes a group of disorders in the development of movement and posture, causing activity limitations, which are attributed to non-progressive disturbances that occurred in the developing brain. It is the most common cause of movement disability in childhood. Children with CP may experience a variety of impaired muscle functions, such as spasticity, muscle weakness, and loss of selective motor control. Muscle structural changes are caused to activate of mechanisms that are limited function with growing and maturation. The weakness found in children with CP is attributable to both altered neural mechanisms and muscle tissue changes. Several factors affect the level of weakness found in the muscles of children with CP. First, weakness may differ between proximal and distal limb muscles. Stackhouse et al. found that the maximum voluntary contraction (MVC) was more impaired in the plantar flexors than the quadriceps of children with mild CP compared with controls. Second, the peak torque may vary according to the velocity of limb movement. Peak torque of the knee flexors and extensors in 24 children with CP was found to decrease with increasing velocity on an isokinetic machine. Third, peak torque may vary according to muscle length. An isokinetic study of 44 children and young people with CP found that peak torque in the hip abductors occurred when the muscle was in a lengthened position with the leg still in adduction. Fourth, the type of contraction was found to consistently affect the peak torque in both children with CP and those who are typically developing, with eccentric force being greater than concentric force in the same muscle. Although all impaired muscle functions limit the performance of daily life activities and participation in a child with CP, a recent study has shown that muscle weakness showed a stronger association with mobility limitations in children with CP than spasticity. Strength training for these children is, therefore, expected to improve or maintain their strength and functional performance.
Peripheral T cell lymphoma and advanced cutaneous T cell lymphomas are aggressive and refractory diseases that are generally treated with chemotherapy. Despite current treatment modalities, only a subset of patients will be cured by the treatment. In this study, four chemotherapeutic agents (L-asparaginase, Methotrexate, Doxil, and Prednisone) will be administered in a combination regimen for patients with relapsed or refractory Peripheral and/or advanced cutaneous T cell lymphoma. Each one of these individual drugs have been shown to have activity to lymphomas. The objective of the study is to determine if the combination of these chemotherapy agents results in higher response and cure rates in this patient population. This will be a single institutional study which will included 32 patients in the Peripheral T cell lymphoma group and 32 patients in the Cutaneous T cell lymphoma group.
