Background

Tumor necrosis factor α (TNF alpha) is an effective pro-inflammatory cytokine, which can kill and inhibit tumor cells. It is mainly produced by activated macrophages and can also be secreted by other types of cells, such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils and neuronal tissues. The members of TNF alpha family exert their cellular effect through two distinct surface receptors of the TNF receptor family, TNFR1 and TNFR2. The pleiotropic biological effects of TNF can be attributed to its ability to simultaneously activate multiple signaling pathways in cells. TNF-induced NF-κB activation promotes the growth, invasion and metastasis of cancer cells.

Soft but Thinner Than Expected
Color: Pink, Color: Pink
This cashmere scarf is very soft and pleasant to the touch. The color is really nice. It is not too bright and is a bit darker than in the pictures, but still very close to the description. What I did not expect is that the scarf is not very wide and is quite thin. Because of that, I was a little disappointed.

A pricy scarf, but worth it for its warmth and softness
Color: Pink
Came in a box that would look like it was be used as a gift. Scarf was really soft and warm and the color matches the imaged shown on the product images. The length and size was true to what was said. Gave this as a gift for valentines day and the other person was happy to receive and and like it as well. I will say that the price of the scarf is pretty pricy but I guess that's why you have to pay for a pretty good quality scarf.

Cute, warmth and quality!
Size: Small-X-Large, Color: Undyed Beige, Size: Small-X-Large, Color: Undyed Beige
Comfortable, cute and kept me warm, but not too hot. The cashmere felt great, extremely soft, and it didn’t mess up my hair like a synthetic hat can. We were out in subzero weather, and this baby did its job!

Perfect fit for a small woman or teenager
Size: Small-X-Large, Color: Light Gray
I think this beanie is a great price for the quality. It’s about as soft as wool can possibly be. I was very impressed by the packaging. It made me feel like I was opening a luxury item, which is nice because it was reasonably priced. They even included a bit of extra yarn in case it needs repairs someday. It does fit a bit snug. I have a small head, so it might be uncomfortable for someone with a bigger head. I definitely would NOT buy this for a man. It’s comfortable for a small female only, or a teenager. Overall, I think it’s a good hat for the price.
