RE: Simpson Mending Plate for custom made wood truss. I think boo1 pretty welled summed it up. Based on experience my opinion would be that the liability you would be taking on if you try to show that the mend plates work, would be too high.
Isoniazid is often used as a protective treatment to reduce the risk of TB. D100 might be a medicine called doxycycline, which is a drug used to treatment many different things. Please ask your doctor or pharmacist to talk about this. These people will help you understand your medicine and what it is being used for.
Alinia (nitazoxanide) is an antiprotozoal agent used to treat diarrhea in adults and children caused by the protozoa Giardia lamblia, or the protozoa Cryptosporidium parvum. These protozoa are sometimes the cause of travelers' diarrhea. Alinia is generally well tolerated when taken as directed. Side effects of Alinia are uncommon and may include: abdominal pain, nausea, diarrhea, vomiting, or ; headache. Serious allergic reactions to Alinia are unlikely, but seek immediate medical attention if you have rash, itching, swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing. Doses of Alinia vary according to age.
