Answer:
A pterygium is a growth of the conjunctiva or mucous membrane that covers the white part of your eye over the cornea. Explanation:
The cornea is the clear front covering of the eye. This benign or noncancerous growth is often shaped like a wedge and its treated very fragile.
Answer: A) an incision in the left lower quadrant to access the tumor.
Explanation:
The ascending colon can be found on the ride side of the region of abdomen. The surgeon is required to make an incision on the left quadrant of the abdomen so as to get an access to the tumor which is on the ascending colon. The ascending colon is supplied with the blood by the mesenteric artery (superior). The ascending colon can be mobilized by the making free the fusion fascia. It will be a good idea to protect the abdomen or peritoneum from the contamination caused by the feces.
Answer:
No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.
BUT
In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth. These changes occur in genes that are essential for development, and often disrupt the development of an embryo in its earliest stages.
Explanation:
Background/Objective: The preclinical stage of rheumatoid arthritis (RA) is marked by the existence of antibodies against citrullinated proteins (ACPA), subclinical arthritis, and discomfort. Years before RA manifests clinically, ACPA first appear. Imaging tests have found inflammatory and structural abnormalities in a subset of these people who have ACPA (but not yet RA). The chance of developing RA is higher in this group of patients. Interventions that target this mechanism may be effective for very early interventions, ultimately averting the onset of autoimmune inflammatory illnesses like RA, as T cell mediated B cell activation is a vital step for triggering the beginning of these conditions.
Because it prevents T cell activation and has a well-known favorable safety profile in the treatment of RA, abatacept looks to be a promising method in this endeavor.
To determine whether abatacept, in individuals with ACPA and MRI evidence of inflammation, but have not yet developed RA, may reverse subclinical arthritis as compared to placebo.
These findings indicate that abatacept dramatically reduces subclinical arthritis in people who are at high risk of developing RA. The statistics also lend support to the idea that early intervention could stop or at least delay the onset of RA.
<h3>What is
rheumatoid arthritis (RA)?</h3>
A chronic inflammatory condition, rheumatoid arthritis can harm more than just your joints. Skin, eyes, lungs, heart, and blood vessels are just a few of the physiological systems that the illness might harm in some people.
