Evaluation of an Absorbable Surgical Hemostatic Agent: Thrombi-Gel® Versus Gelfoam-Thrombin
Operation Site BleedThis trial is designed as a prospective, multi-center, randomized, feasibility clinical trial to evaluate the safety and efficacy of Thrombi-Gel as an absorbable surgical hemostat. Within this clinical evaluation, Thrombi-Gel will be compared to the current standard of care, a gelatin sponge (Gelfoam) plus Thrombin JMI, by using a 2:1 randomization ratio. Subjects will be randomized to one of two (2) treatment groups. One (1) group will be treated with Thrombi-Gel, while one (1) group will be treated with the gelatin sponge plus thrombin. All study data will be analyzed according to the subjects' assigned randomization group assignment, regardless of the treatment actually delivered.
The PK/PD Study of SHR2285 Tablets in Healthy Subjects
ThrombosisThrombosis is a maladaptive process of vascular occlusion and remains a primary cause of cardiovascular morbidity and mortality, The dose-limiting issue with available anticoagulant therapies is bleeding. The primary objective of this study is to assess the safety and tolerability of SHR2285 tablets in healthy subjects. In addition, this study will provide information on Pharmacokinetics and Pharmacodynamics of SHR2285 tablets in healthy subjects.

Robotic Sock Technology for Prevention of Deep Vein Thrombosis and Joint Contracture
Deep Vein ThrombosisAnkle Joint ContractureThe research team's aim is to investigate the effects of the team's soft robotic socks in providing assisted ankle dorsiflexion-plantarflexion and promoting venous blood flow in stroke patients. Specifically, the investigators intend to 1) observe the development of joint contracture in terms of the range of motion of the ankle joint given the use of the device 2) monitor the presence of blood clots in the deep veins using compression Duplex ultrasonography given the use of the sock device. The investigators hypothesize that a soft robotics approach can provide compliant actuation to simulate natural ankle dorsiflexion and plantarflexion, which will consequently promote blood circulation in the lower leg of stroke patients who have not previously developed ankle joint contracture. This will prevent the occurrence of DVT and movement in the ankle joint will alleviate stiffness. This robotic sock intervention is to prevent the development of ankle joint contracture so established ankle contractures will be excluded from this study.
CES1 Crossover Trial of Clopidogrel and Ticagrelor
Myocardial InfarctionThrombosis1 moreThe purpose of this investigation is to evaluate when genetic variation in the carboxylesterase 1 (CES1) gene influences antiplatelet therapy response, as assessed by ex vivo platelet aggregometry, in healthy participants treated with clopidogrel and ticagrelor. We hypothesize that genetic variation in CES1 will significantly impact on-clopidogrel platelet aggregation while having a minimal effect in ticagrelor-treated subjects. Specific Aim: To conduct a prospective randomized crossover study of clopidogrel and ticagrelor in healthy individuals stratified by CES1 genotype. Participants will be recruited by CES1 genotype into a randomized crossover study of clopidogrel (75 mg daily for 7d) and ticagrelor (90 mg twice daily for 7d) with extensive phenotyping including ex vivo platelet aggregometry performed pre- and post-drug administration in order to assess the interaction of genotype and drug choice on on-treatment platelet function.
Rivaroxaban for Treatment in Venous or Arterial Thrombosis in Neonates
ThromboembolismThe purpose of this study is to find out whether rivaroxaban is safe and effective to use in children age newborn to less than 6 months and how long it stays in the body and how it is used in the body. Safety will be assessed by looking at the incidence and types of bleeding events. There will also be a check for worsening of blood clots.
CV004-007 Thrombosis Chamber Study
ThrombosisThe purpose of this study is to determine whether BMS-986120, aspirin, or aspirin and clopidogrel decrease blood clotting.
Evaluation of Factors II, VII, IX, X, and Proteins C and S, Following High-dose Vitamin K Supplementation...
ThrombosisThe purpose of this study is to evaluate factor levels of the pro coagulant factors II, VII, IX, X, and the anticoagulant factors protein C and S in healthy volunteers during the intake of elevated levels of vitamin K in order to investigate whether there is any evidence that high dose vitamin K intake increases plasma coagulation factor activity.
Neuromuscular Electrical Stimulation Following Total Hip Arthroplasty
Deep Vein ThrombosisTotal Hip ArthroplastyPatients post total hip arthroplasty (THA) remain at high risk of developing Deep Vein Thrombosis (DVT) during the recovery period following surgery despite the availability of effective pharmacological and mechanical prophylactic methods. The use of calf muscle neuromuscular electrical stimulation (NMES) during the hospitalised recovery period on this patient group may be effective at preventing DVT. However, the haemodynamic effectiveness and comfort characteristics of NMES in post-THA patients immediately following surgery have yet to be established. The main objectives are: To establish if patients in the early post-operative period have tolerance for NMES. To determine if applying NMES to patients immediately post-THA increases venous outflow from the lower limb over resting conditions.
