I need a fresh bank of multiple-choice questions that will test students on key medical concepts, procedures, and terminology. The questions should be clear, accurate, and pitched at an undergraduate level so they challenge learners without overwhelming them. What I already know • Format: strictly multiple choice – one correct answer with three or four plausible distractors. • Audience: students preparing for medical exams or clinical rotations. • Topic scope: core medicine (anatomy, physiology, pathology, pharmacology, clinical scenarios). Feel free to propose a balanced mix across these areas, but avoid stepping into nursing-specific or veterinary content. What I expect from you • A well-structured question set (let me know how many you recommend for s...

I am compiling an in-depth scientific report that connects three threads: the evidence that isotretinoin can precipitate affective (mood) disorders, the cellular and molecular pathways that might explain this association, and the ways mesenchymal stem cells (MSCs) could mitigate or repair the resulting neurobiological damage. Include any retinoic acid affects and repair pathways/pathophysiology like on Mitochondria. You will comb through the current biomedical literature, evaluate pre-clinical and clinical findings, and then weave those data into a clear, logically structured narrative. I expect precise referencing, critical appraisal of study quality, and thoughtful discussion of biological plausibility. Graphical illustrations of key pathways or study timelines are welcome where they ai...

I have a collection of LaTeX source files that cover Calculus and Algebra, Physics and Chemistry, as well as Biology and Statistics. The technical content is already written; what I need now is clear, concise explanatory comments inserted directly into the .tex code so another instructor—or an advanced student peeking under the hood—can immediately understand the reasoning behind each formula, derivation, and data set. Because I use a mixed tool-chain, you’re free to stick with the core LaTeX environment or bring in TikZ, PGF, AMS-LaTeX, or any other package you feel suits the job; I have no fixed preference as long as the final documents still compile cleanly with pdfLaTeX. Scope of work • Open each provided .tex file and weave in thoughtful, well-formatted comm...
