Unsymmetric Bending01:18

Unsymmetric Bending

Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from those in symmetrical bending, and are essential for designing structures to withstand different loading conditions. In unsymmetrical bending, the neutral axis—where stress is zero—does not necessarily align with the geometric axes of the cross-section. The orientation of the...
Oriented Surfaces01:30

Oriented Surfaces

A surface is called orientable if a consistent choice of unit normal vector can be made at every point on the surface. A thin soap film stretched across a wire loop provides a familiar example. The film separates the air on one side from the air on the other, so one side can be selected as positive and the opposite side as negative. Once this choice is made, a unit normal vector can be assigned smoothly across the entire surface.At each point on the soap film, a unit normal vector points...
Mohr's Circle for Plane Strain01:18

Mohr's Circle for Plane Strain

Mohr's circle is a crucial graphical method used to analyze plane strain by plotting strain on a set of cartesian coordinates, where the abscissa is normal strain ∈ and the ordinate is shear strain γ. Similarly to Mohr’s circle for plane stress, two points X and Y are plotted. Their coordinates are (∈x, -γXY) and (∈Y, γXY), respectively.
Mohr's circle visually represents the strain states under various conditions, which is essential for understanding material behavior. The center of Mohr's...
Mohr's Circle for Moments of Inertia01:10

Mohr's Circle for Moments of Inertia

Mohr's circle is a graphical method to determine an area's principal moments of inertia by plotting the moments and product of inertia on a rectangular coordinate system.
Symmetric Member in Bending01:07

Symmetric Member in Bending

In the study of the mechanics of materials, analyzing the behavior of prismatic members under opposing couples is crucial for understanding internal stress distributions, which are essential for structural design. When subjected to couples, a prismatic member experiences internal forces that maintain equilibrium. A couple, characterized by two equal and opposite forces, creates a moment but no resultant force. The internal forces at any section cut of the member must balance these external...
Pleiotropy01:33

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Area of Science:

  • Neurology
  • Genetics
  • Developmental Biology

Background:

  • Möbius syndrome presents as congenital bilateral facial and abducens nerve palsies.
  • Patients often experience difficulties smiling and lip closure during mastication.
  • Associated conditions include craniofacial, musculoskeletal, and developmental disorders.

Purpose of the Study:

  • To explore the etiology of Möbius syndrome.
  • To detail the primary treatment for facial reanimation in Möbius syndrome patients.
  • To highlight the role of neurovascular free muscle transfer in restoring smiles.

Main Methods:

  • Review of current scientific hypotheses on Möbius syndrome etiology.
  • Description of neurovascular free muscle transfer using the gracilis muscle.
  • Discussion of nerve grafting options (trigeminal, hypoglossal, accessory nerves).

Main Results:

  • Growing evidence suggests an embryological disruption of subclavian artery development as a potential cause.
  • Gracilis muscle transfer with direct nerve repair to the masseteric nerve is the preferred method.
  • Alternative nerve sources include partial hypoglossal or accessory nerves.

Conclusions:

  • Neurovascular free muscle transfer offers a viable solution for facial reanimation in Möbius syndrome.
  • Cerebral plasticity enhances surgical outcomes, potentially enabling satisfactory spontaneous smiles.
  • Further research into the syndrome's etiology is warranted.
