Summary
Soy isoflavone supplementation shows promise in clinical trials, particularly for healthy individuals. Emerging research suggests potential benefits for elite athletes, indicating a new therapeutic application.
Area of Science:
- Nutritional Science
- Clinical Research
- Bibliometrics
Background:
- Soy isoflavones have diverse therapeutic applications explored in clinical trials.
- Bibliographic analysis is crucial for understanding research trends and identifying new uses.
Purpose of the Study:
- To identify predominant therapeutic areas of soy isoflavone use in clinical trials.
- To assess emerging fields of soy isoflavone application through bibliographic resource analysis.
Main Methods:
- Searched MEDLINE database up to December 31, 2004, for clinical trials on soy.
- Reviewed 86 selected abstracts, assessing variables and subject demographics (n=3280).
- Analyzed study focus, including metabolite levels, hormone/lipid profiles, and specific populations.
Main Results:
- Most studies (71%) involved healthy individuals, with a focus on metabolite, hormone, and lipid profiles.
- Postmenopausal women constituted a significant portion of participants (71%).
- After 2000, two studies highlighted positive results in elite athletes (gymnasts, judoists).
Conclusions:
- Soy isoflavone research has historically focused on healthy populations and metabolic profiles.
- The competitive sports elite represents an emerging area for soy supplementation research.
- Soy supplementation may offer potential benefits for athletic performance and recovery.

01:22Bioavailability: Influencing Factors
Bioavailability refers to the extent and rate at which a drug reaches systemic circulation in its active form. Extent refers to the amount of the drug that makes it into circulation, while rate is the speed at which it enters circulation. It is influenced by several factors critical for optimizing drug formulations, dosing regimens, and therapeutic outcomes.Physicochemical properties of drugs and formulationsThe solubility, stability, and dissolution rate of a drug significantly impact its...
02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

02:35Key Elements for Plant Nutrition
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...
01:22Bioavailability Enhancement: Determination and Conceptual Approaches in Overcoming Bioavailability Problems
Bioavailability is a critical pharmacological concept that measures the extent and rate at which an active drug ingredient or therapeutic moiety enters the systemic circulation, remaining unchanged. It's a pivotal factor in determining a drug's efficacy and safety.The Biopharmaceutics Classification System (BCS) plays an essential role in drug development by categorizing drugs into four classes based on their solubility and permeability. This classification aids in understanding drug absorption...
01:13Bioavailability: Overview
Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...
01:17Bioavailability: Overview
Bioavailability refers to the proportion of an administered drug that reaches the systemic circulation in its active, unaltered form. It is a crucial pharmacokinetic parameter that determines the effectiveness of a drug in achieving its intended therapeutic outcomes. The route of administration significantly influences bioavailability, with intravenous administration achieving 100% bioavailability as the drug directly enters the bloodstream. In contrast, oral administration often results in...
