Here are 2 medical images related to cancer:
1. Invasive Adenocarcinoma — Histopathology (H&E Stain)
Invasive Adenocarcinoma Histology
A hematoxylin and eosin (H&E) stained section showing invasive prostate adenocarcinoma. Malignant glands (small, rigid, irregular) are seen infiltrating between larger benign glands. Key features include cellular atypia, hyperchromatic nuclei with prominent nucleoli, and a desmoplastic stromal response — all hallmarks of invasive malignancy. (Source: WebPathology)
2. Tumor MRI — Patient-Derived Xenograft (PDX) Models
Cancer Tumor MRI
A composite MRI grid showing four different cancer tumor models (BK-12, ED-15, HL-16, LA-19) using T2-weighted and T1-weighted sequences with contrast (Gd-DOTA). The images highlight the radiological heterogeneity of tumor phenotypes — varying signal intensities, enhancement patterns, and vascular characteristics used in preclinical oncology research.

Alzheimer's disease overview pathology symptoms treatment

GradeResponse
Here are 5 sentences about Alzheimer's disease:
  1. Alzheimer's disease (AD) is the most common cause of dementia, accounting for 60–80% of cases, and is characterized by progressive cognitive decline that interferes with daily functioning.
  2. The disease is defined pathologically by the accumulation of amyloid-beta plaques and neurofibrillary tangles (composed of hyperphosphorylated tau protein) in the brain, leading to widespread neuronal loss.
  3. Early symptoms typically include short-term memory loss and difficulty recalling recent events, which gradually worsen to include language problems, disorientation, poor judgment, and changes in behavior and personality.
  4. There is currently no cure for Alzheimer's disease; management focuses on slowing symptom progression using medications such as cholinesterase inhibitors (e.g., donepezil) and memantine, alongside behavioral and caregiver support (Harrison's Principles of Internal Medicine, 21st ed., p. 12261).
  5. Risk factors include advancing age, the APOE-ε4 genetic allele, family history, cardiovascular disease, and low cognitive reserve, while active research continues into disease-modifying therapies targeting amyloid and tau pathways.
