Approximately 31 participants were planned to be enrolled in two groups, with approximately 25 in Group 1 and approximately six in Group 2.

Study of Metabolic Absorption Rates of DHA-Taurine as a Source of Omega-3 Fatty Acids

* Omega-3 fatty acids such as docosahexaenoic acid (DHA) have well-established health benefits and are widely used to improve cardiometabolic health. However, conventional DHA supplements require normal digestion and absorption of dietary fat, which may limit their effectiveness in individuals with impaired fat absorption or those consuming very low-fat diets. * This study investigates the absorption of a novel DHA-containing molecule, DHA-taurine (DHA-T), compared with a conventional DHA ethyl ester (DHA-EE) supplement. Preclinical studies suggest that DHA-T may be absorbed through a different mechanism that is less dependent on normal fat digestion and may therefore provide a more effective way of delivering DHA. * The primary objective is to compare plasma DHA concentrations following administration of DHA-T and DHA-EE under fasting conditions without a meal. The study also evaluates plasma DHA-T concentrations to improve understanding of the absorption, transport, and metabolism of DHA-T in humans. * This is a randomized, double-blind, crossover study in seven healthy male volunteers aged 18 to 30 years. Each participant receives both study interventions in random order, separated by an approximately two-week washout period, allowing each participant to serve as his own control. On each study day, participants undergo repeated blood sampling and ultrasound measurements of gallbladder volume over an 8-hour absorption test following administration of the assigned study intervention. * The results of this study will improve understanding of the absorption and metabolism of DHA-T and may support the future development of omega-3 formulations that are effective even when normal fat absorption is impaired.

Pharmacokinetics of Oral Calcium Carbonate in Parturients

This study investigates the time course of change in calcium in the blood after a pregnant subject takes an oral dose of calcium carbonate (commonly marketed as "Tums"). Midway through the trial, with IRB permission, the oral calcium formulation was switched to calcium citrate to test whether this, better-absorbed formulation might prove more effective in increasing serum calcium. This information is important for trials investigating whether oral calcium can reduce postpartum hemorrhage, bleeding after delivery.

A First-in-Human SAD and MAD Study in Healthy Participants to Evaluate Oral YR011 Tablet

This is a Phase I clinical trial (protocol number: YR-011-B01) sponsored by Hangzhou Yirui Pharmaceutical Technology Co., Ltd., focusing on the novel oral small-molecule drug YR011 (active ingredient: PA032, a Kv1.3 channel blocker). The trial aims to evaluate the safety, tolerability, and pharmacokinetics (PK) of YR011 in healthy adult participants. The trial has two stages: Single Ascending Dose (SAD) and Multiple Ascending Dose (MAD), with about 64 participants total (32 per stage). Participants are divided into 4 cohorts per stage (8 people per cohort), randomized 6:2 to receive YR011 or placebo in a double-blind manner. For the SAD stage, 4 dose levels are tested as a single oral dose under fasting conditions; for the MAD stage, 4 dose levels are given twice daily for 7 days plus one extra dose on Day 8. Key procedures include screening (up to 28 days before enrollment), baseline assessments, drug administration, and follow-up (7 days for SAD, 14 days for MAD). Safety is the primary endpoint (measured by treatment-related adverse events), with secondary endpoints including PK parameters (e.g., plasma concentration, half-life) and dose accumulation. Eligible participants are 18-60 years old, healthy, and able to comply with trial procedures; those with major diseases, drug allergies, or recent medication use are excluded. The trial follows ICH-GCP and FDA regulations, with a Safety Review Committee overseeing dose escalation and safety monitoring. All data is collected via electronic case report forms (eCRFs) and kept confidential.

Liposomal Bupivacaine Versus Plain Bupivacaine After Intercostal Injections For Pain Management After Thoracoscopy

The purpose of this study is to assess pharmacokinetics of liposomal bupivacaine (Exparel) after multilevel intercostal injections of this local anesthetic for pain control during and after thoracoscopic surgeries. The specific aim of this study is to evaluate plasma concentration of bupivacaine after intraoperative intercostal injections of 266 mg of liposomal bupivacaine and compare it to plasma concentrations of bupivacaine after intercostal injections of 2mg/kg of 0.5% plain Bupivacaine with maximal dose of 30 ml or 150 mg. The hypothesis of the study is that plasma concentration of bupivacaine after intercostal injections of 266 mg of liposomal bupivacaine will be similar to concentrations after injections of plain bupivacaine, and will remain below the toxic level threshold range of 2000-3000 ng/mL (2-3 mg/L) at which central nervous system and cardiovascular adverse events would be expected to occur. The secondary objective is to evaluate if intercostal injections of 266 mg of liposomal bupivacaine will significantly reduce opioid consumption and postsurgical pain, within the first 48 hours and up to 3 months after minimally invasive thoracic surgeries, to determine if both acute and chronic post-thoracotomy pain can be decreased by intraoperative intercostal injections of liposomal bupivacaine. Additionally, the rate of pneumonia, the rate of atrial fibrillation and length of hospital stay will be assessed as secondary outcomes after thoracic surgeries. These outcomes can be affected by the level of postoperative pain and inflammation. Significance of this study: If positive, the results of this research have the potential to significantly improve pain management after thoracoscopic surgery. Based on prior experience, prolonged analgesia after liposomal bupivacaine injection is safe, and may help reduce perioperative opioid consumption and decrease opioid related complications. It will improve patient comfort, eliminate need for indwelling neuraxial catheters and risks associated with them.

Antibiotics as Adjuncts to Periodontal Therapy:Pharmacokinetic Considerations and Dosing Strategies

Periodontitits is a bacteria induced inflammatory disease that destroys the supporting tissues of the tooth and leads to tooth loss. Treatment consists mainly of the mechanical cleaning of the tooth surfaces in order to remove the bacterial deposits (plaque and calculus). This procedure can reduce the level of pathogenic bacteria but it can not eradicate them. In severe cases, for the complete resolution of the disease, the elimantion of certain species of bacteria is needed. In order to achieve that, the combination of different regimens of antibiotics adjunctive to the mechanical treatment has been proposed. However, dosage and duration of antimicrobial therapy should be optimal and not excessive as issues may arise related to increased antimicrobial resistance in the population and the individual due to habitual prescription of wide-spectrum antibiotic regimens, horizontal gene transfer and genetic mutation. In the present study, in an effort to optimize the dosage and duration of the antimicrobial regimen, we will determine the pharmacokinetics (PK) and pharmacodynamic (PD) properties of the MET-AMO combination and of AZI in Gingival Crevicular Fluid (GCF), saliva and serum in severe periodontitis patients during and after either a 3-day or a 7-day course of treatment.

PK/PD of Caspofungin in Children Severe Infection

Caspofungin is an anti-fungal drug mainly metabolized by the liver. The pathophysiological status of children with severe infection will affect the metabolism of caspofungin in the body especially in the case of liver dysfunction. There is little metabolism of caspofungin through the kidney and continuous renal replacement therapy and renal function have little influence on the pharmacokinetics of caspofungin. The study aim to investigate PK/PD of caspofungin in children with specific pathophysiological conditions, such as liver insufficiency, hypoproteinemia, ECMO treatment, or sepsis.
