-        PharmKG stands for Pharmaceutical Knowledge Graph, representing a structured database of drug-related knowledge. It includes relationships between drugs, diseases, proteins, genes, and other entities in biomedicine and pharmacy.
-        Key features and uses of PharmKG include:
-            Data Integration: Integrates information from various biomedical databases.
-            Relationship Representation: Represents complex relationships like drug-disease, drug-protein, drug-side effects in graph form.
-            Drug Development Support: Used in discovering new drug targets, drug repurposing research.
-            Side Effect Prediction: Can be used to predict drug interactions and potential side effects.
-            Personalized Medicine: Helps analyze relationships between patient genetic characteristics and drug responses.
-            AI Research: Used to train machine learning models to discover new biomedical knowledge.
-            Decision Support: Provides comprehensive information for medical professionals planning patient treatment.
-        PharmKG serves as an important tool in pharmaceutical research and clinical decision-making by systematically organizing and analyzing complex drug-related information.

-                ## PharmAI: Your Expert Pharmacology Assistant
-
-                Welcome to PharmAI, a specialized chatbot powered by Google's Gemini 2.0 Flash model. PharmAI is designed to provide expert-level information on pharmacological topics, leveraging extensive pharmacological knowledge graphs.
-
-                **Key Features:**
-
-                *   **Advanced Pharmacological Insights**: PharmAI provides structured and detailed answers based on extensive pharmacological knowledge graphs.
-                *   **Reasoning and Inference**: The chatbot demonstrates ability to process complex, multifaceted questions by reasoning and inferring from available information.
-                *   **Structured Responses**: Responses are logically organized to include definitions, mechanisms of action, indications, dosage, side effects, drug interactions, pharmacokinetics, and references where applicable.
-                *   **Thought Process Display**: Observe the model's thought process as it generates responses (experimental feature).
-                *   **Conversation History**: PharmAI remembers previous parts of conversations to provide more accurate and relevant information over multiple exchanges.
-                *   **Streaming Output**: The chatbot streams responses for an interactive experience.
-
-                **Drug Development Support Features:**
-
-                *   **Drug Candidate Suggestions**: Suggests potential drug candidates for specific diseases or targets.
-                *   **Structure-Activity Relationship Analysis (SAR)**: Analyzes relationships between compound structures and their activities.
-                *   **ADMET Evaluation**: Evaluates pharmacokinetic and toxicity properties of candidate compounds.
-                *   **Preclinical Assessment Information**: Provides evaluation information based on preclinical research data.
-
-                **How to Use:**
-
-                1.  **Start Conversation (General Pharmacology)**: Enter your question in the "Expert" tab.
-                2.  **Drug Development Questions**: Enter drug development related questions in the "Drug Development Support" tab.
-                3.  **Use Example Prompts**: Utilize provided example questions to request more specific information.
-                4.  **Reset Conversation**: Use the "Reset Chat" button to start a new session.
-
-                **Important Notes:**
-
-                *  The 'Thinking' feature is experimental but shows some steps of the response generation process.
-                *  Response quality depends on the specificity of input prompts.
-                *  This chatbot is an informational tool and should not be used for medical diagnosis or treatment recommendations.
