Reactive attachment disorder (RAD) is described in clinical literature as a severe disorder that can affect children, although these issues do occasionally persist into adulthood. [1] [2] [3] RAD is characterized by markedly disturbed and developmentally inappropriate ways of relating socially in most contexts. It can take the form of a ...
Myosin-9 also known as myosin, heavy chain 9, non-muscle or non-muscle myosin heavy chain IIa (NMMHC-IIA) is a protein which in humans is encoded by the MYH9 gene. [5] [6]Non-muscle myosin IIA (NM IIA) is expressed in most cells and tissues where it participates in a variety of processes requiring contractile force, such as cytokinesis, cell migration, polarization and adhesion, maintenance of ...
The myosin head is the part of the thick myofilament made up of myosin that acts in muscle contraction, by sliding over thin myofilaments of actin.Myosin is the major component of the thick filaments and most myosin molecules are composed of a head, neck, and tail domain; the myosin head binds to thin filamentous actin, and uses ATP hydrolysis to generate force and "walk" along the thin filament.
Here are the symptoms and warning signs every parent needs to know. Body dysmorphic disorder can begin as early as 12 and 13 years old. Here are the symptoms and warning signs every parent needs ...
MHC-β is a 223 kDa protein composed of 1935 amino acids. [7] [8] MHC-β is a hexameric, asymmetric motor forming the bulk of the thick filament in cardiac muscle.MHC-β is composed of N-terminal globular heads (20 nm) that project laterally, and alpha helical tails (130 nm) that dimerize and multimerize into a coiled-coil motif to form the light meromyosin (LMM), thick filament rod.

There is a lack of consensus about the precise meaning of the term "attachment disorder", but there is general agreement that such disorders arise only after early adverse caregiving experiences. Reactive attachment disorder indicates the absence of either or both the main aspects of proximity seeking to an identified attachment figure. This ...
MHC-α and MHC-β display significantly different enzymatic properties, with α having 150-300% the contractile velocity and 60-70% actin attachment time as that of β. [11] [13] It is the enzymatic activity of the ATPase in the myosin head that cyclically hydrolyzes ATP, fueling the myosin power stroke.
Long COVID symptoms in kids, teens The study included 5,300 younger school-age children and teens from more than 60 health care facilities across the U.S. between March 2022 and December 2023.
