  2. Rh blood group system - Wikipedia

    en.wikipedia.org/wiki/Rh_blood_group_system

    This real factor found in rhesus macaque was classified in the Landsteiner-Weiner antigen system (antigen LW, antibody anti-LW) in honor of the discoverers. [53] [54] It was recognized that the Rh factor was just one in a system of various antigens. Based on different models of genetic inheritance, two different terminologies were developed ...

  3. Arthritis - Wikipedia

    en.wikipedia.org/wiki/Arthritis

    These might include: rheumatoid factor, antinuclear factor (ANF), extractable nuclear antigen, and specific antibodies. [65] Rheumatoid arthritis patients often have high erythrocyte sedimentation rate (ESR, also known as sed rate) or C-reactive protein (CRP) levels, which indicates the presence of an inflammatory process in the body.

  4. Rate-determining step - Wikipedia

    en.wikipedia.org/wiki/Rate-determining_step

    For the NO 2 –CO reaction above, the rate depends on [NO 2] 2, so that the activated complex has composition N 2 O 4, with 2 NO 2 entering the reaction before the transition state, and CO reacting after the transition state. A multistep example is the reaction between oxalic acid and chlorine in aqueous solution: H 2 C 2 O 4 + Cl 22 CO 2 ...

    en.wikipedia.org/wiki/Halogen

    The halogens (/ ˈ h æ l ə dʒ ə n, ˈ h eɪ-,-l oʊ-,-ˌ dʒ ɛ n / [1] [2] [3]) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors [4] would exclude tennessine as its chemistry is unknown and is theoretically expected to ...

  6. Pearson correlation coefficient - Wikipedia

    en.wikipedia.org/wiki/Pearson_correlation...

    Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.

    Autoimmune diseases affecting other organs most commonly associated with Hashimoto's thyroiditis include celiac disease, type 1 diabetes, vitiligo, alopecia, [51] Addison disease, Sjogren's syndrome, and rheumatoid arthritis [13] [52] Autoimmune thyroiditis has also been seen in patients with autoimmune polyendocrine syndromes type 1 and 2.

    Drawing showing the relative sizes of sensors used in most current digital cameras. Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter.
