The technical aspects of performing LIPS (Luciferase Immunoprecipitation Systems) are described. The overall approach involves expressing chimeric genes encoding antigens fused to Renilla luciferase (Ruc) in mammalian cells. Crude Ruc-antigen extracts are then prepared and, without purification, employed in immunoprecipitation assays to quantify antibodies.

Transcranial magnetic stimulation (TMS) has proven to be a useful tool in investigating the role of the articulatory motor cortex in speech perception. This article describes how to record motor evoked potentials (MEPs) from the lip muscles and how to disrupt the motor lip representation using repetitive TMS.

Source: Carmen Black, Matthew Goldenberg, and Jaideep Talwalkar; Yale School of Medicine The mental status exam is a clinical evaluation of emotional, perceptual, and cognitive functioning that spans both the fields of psychiatry and neurology. Developing skill in the psychiatric portions of the examination are important to describe salient aspects of the patient's mental state that may be observed during routine history and/or physical exam. Proficiency in the cognitive portions of this...

Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA The simplest ophthalmoscopes consist of an aperture to look through, a diopter indicator, and a disc for selecting lenses. The ophthalmoscope is primarily used to examine the fundus, or the inner wall of the posterior eye, which consists of the choroid, retina, fovea, macula, optic disc, and retinal vessels (Figure 1). The spherical eyeball...
FAQs
Comparing both sides helps identify differences in contour, swelling, or movement that may otherwise be overlooked. Observing lip motion adds functional information to the visual assessment, while asymmetry can be considered alongside symptoms, trauma, inflammation, infection, or other local and systemic clues. These findings help determine whether further oral or medical evaluation is warranted.
Inspection reveals visible features such as color, moisture, surface changes, lesions, swelling, and mucosal continuity. Palpation adds information about texture, tenderness, and areas that may not be obvious visually. Using both approaches gives a more complete assessment of the lips and surrounding tissues, supporting a more focused differential diagnosis than either method alone.
Lip findings should be interpreted in relation to the patient’s symptoms and broader clinical context. Local clues may include trauma, infection, inflammation, or oral-health problems, whereas color or surface changes may also raise consideration of vascular, nutritional, or systemic conditions. The examination does not stand alone; its findings help guide the next stage of evaluation.
Adequate lighting is essential for judging color, surface changes, lesions, moisture, and mucosal continuity accurately. A systematic assessment should include visual inspection followed by palpation, with attention to symmetry, swelling, tenderness, texture, movement, and sensation. Comparing the two sides and examining surrounding tissues reduces the chance that subtle or localized abnormalities will be missed.
The clinician first observes the lips and adjacent tissues, then compares both sides for symmetry and movement. Visual assessment considers color, moisture, lesions, swelling, surface changes, and continuity of the mucosa. Palpation evaluates texture and tenderness, while sensation is also assessed. The findings are then related to symptoms and other relevant clinical clues.
Further evaluation may be appropriate when the examination identifies unexplained lesions, persistent swelling, marked tenderness, altered sensation, asymmetry, or notable color and surface changes. The significance depends on associated symptoms and whether findings suggest trauma, infection, inflammation, vascular change, nutritional problems, or systemic disease. In this way, the examination helps narrow differential diagnosis and guide oral or medical assessment.
Because the assessment records visible and palpable features such as lesion appearance, swelling, tenderness, texture, moisture, and mucosal continuity, it can provide a comparison point during follow-up. Repeating the examination allows clinicians to relate changes to symptoms and judge whether findings are improving, persisting, or changing, supporting ongoing clinical decisions and treatment monitoring.
