In one sentence, describe what the following article is about: Non-steroidal anti-inflammatory drugs (NSAIDs) are prescription painkillers that reduce inflammation. They work by inhibiting the "bad" COX-2 enzymes that mediate joint inflammation while allowing the "good" COX-1 enzymes that maintain blood flow to the kidney and stomach lining to work as normal. These drugs have a high safety margin when used correctly, are less likely than other painkillers to cause potentially nasty side effects such as gastric ulceration, and bleeding disorders. NSAIDs commonly prescribed by vets are meloxicam (Metacam), carprofen (Rimadyl), and robenacoxib (Onsior). The maintenance dose of meloxicam is 0.05mg/kg by mouth, with or after food, once daily. The oral suspension contains 1.5mg/ml and so a typical 30kg (66lb) Lab requires 1 milliliter (0.034floz) daily with his food. Aspirin (acetylsalicylic acid) provides mild to moderate pain relief. However, long-term use is associated with gastric ulceration, especially when given on an empty stomach. This happens because aspirin reduces blood flow to the gut lining, stomach, and kidney. Aspirin should never be given in addition to an NSAID medication. When combined, both drugs are even more likely to cause gastric ulceration, with serious consequences. If no other pain relief is available, a healthy dog can be given aspirin in doses of 10mg/kg given twice a day, with or after food. Aspirin commonly comes in 300mg tablets, so a typical dose for a 30kg (66lb) Labrador would be one tablet twice a day with food. Another option for moderate pain relief is Paracetamol (Acetaminophen). However, take care when using this medication because exceeding the recommended dose overloads the liver with a toxic metabolite called N-acetyl-p-aminobenzoquinonimine, which can cause liver damage, and ultimately liver failure. A vet-approved prescription medication is preferred, but if no other option for pain relief is available, give Paracetamol with food and observe the correct dosage. The dose is 10mg/kg by mouth, twice a day, with or after food. Most tablets are 500mg and so a 30kg (66lb) Labrador can take a maximum of three-fifths of a tablet twice daily. If in doubt, always give a lower dose and for small dogs, consider using the pediatric suspension. An exciting new option for the treatment of arthritis is stem cell therapy. This differs from previous generations of therapy in that the principle is to encourage repair of damaged tissue, rather than merely treating the discomfort. This therapy involves harvesting fat from the dog under anesthetic, extracting stem cells from the fat sample, activating the stem cells in a laboratory, and then injecting the activated stem cells into the joints. A few veterinary clinics are now able to offer this treatment on site. Many animals are so improved a few weeks after treatment that they no longer need to take pain medication.
Summary: Give your dog NSAIDs to relieve his pain. Try relieving your dog's pain with aspirin. Talk to your vet about the proper dosage for Paracetamol. Talk to your vet about stem cell therapy.

In one sentence, describe what the following article is about: Take your friend aside and tell them that you need to talk about something that is important to you. Explain how it made you feel to see or hear others talking about you. If it feels like your friend isn't listening, try to stay calm. You won't make any headway if you start fighting during your talk. Only confront your friend if you are certain they have been talking about youdon't just go on someone else's word. It's no fun to be falsely accused, and you may lose a friend if they haven't done anything wrong. Avoid getting into a back-and-forth. Try to keep the conversation focused on the fact that gossiping is hurtful and wrong. Your friend may feel defensive or have reasons that they think justify gossiping, but there is no excuse. Be firm about the fact that you do not like participating in gossip or hearing it about yourself. Tell them that they hurt your feelings and that you're concerned about the friendship. For example, perhaps you told your friend something private about your family, and they shared it with others. Say something like, "As your friend, I want to be able to vent to you about my family and trust that you'll keep it between us. Just because I tell you something doesn't give you the right to tell other people about it." If you're really hurt by being gossiped about, you may want some space, or a genuine apology. Be honest and tell your friend what (if anything) they can do to regain your trust. Let them know that you value honesty and loyalty in a friend. Make it clear that if they can't uphold these values, you won't be able to continue the friendship. Be specific about what you expect from them. For example, say, "If I share something personal with you, I expect you to keep that between you and me. If other people want to know something about me, they can ask me themselves. I'll do the same for you."
Summary:
Find a private place to talk. Express your concerns. Tell your friend what you need from them.
