gingipain Porphyromonas gingivalis periodontal virulence

Finding Sources
The first file appears base64-encoded. Let me decode it and read the Periobasics file with a different encoding, while also getting more PubMed details.
Running Command

cd /home/daytona/workspace/attachments/789452a4-688c-4681-8262-7f302d8b6b3a/ && python3 -c " import base64 with open('Biofilm and Periodontal Microbiology.txt','rb') as f: raw = f.read() try: decoded = base64.b64decode(raw).decode('utf-8','ignore') print(decoded[:8000]) except: print(raw[:8000].decode('utf-8','ignore')) "

Running Command

cd /home/daytona/workspace/attachments/789452a4-688c-4681-8262-7f302d8b6b3a/ && python3 -c " with open('Microbiology of periodontal diseases (Periobasics).txt','rb') as f: raw = f.read() # try latin-1 text = raw.decode('latin-1','ignore') print(text[:8000]) "

gingipain cysteine protease periodontal pathogenesis mechanism

The Biofilm file is binary/encoded. Let me extract the text properly and read more of the Periobasics file, while also fetching key PubMed abstracts.

Good. Now let me read more of the gingipain sections from the Periobasics file and get more PubMed details on key landmark articles.
