Source: Wiegand, D. J., et al. Cell-free Protein Expression Using the Rapidly Growing Bacterium Vibrio natriegens. J. Vis. Exp. (2019).This video demonstrates the preparation of a cell extract from Vibrio natriegens, a rapidly growing bacterium known for its high protein synthesis rate. The bacterial pellet is washed and resuspended in lysis buffer before sonication on ice to prevent cellular degradation. The lysate is centrifuged to separate insoluble cell debris, and the cell extract is...

Psoriasis is a chronic, immune-mediated inflammatory skin disease. The Goeckerman regimen, formulated for the treatment of psoriasis, consists of exposure to ultraviolet B (UVB) light and application of crude coal tar (CCT). The following protocol is for the administration of Goeckerman therapy for the treatment of moderate-to-severe psoriasis.

FAQs
Its therapeutic action includes slowing excessive epidermal cell growth and helping normalize keratinization, the process by which skin cells mature and form the outer layer. These effects address the hyperproliferative and scaling components of disorders such as psoriasis. By acting on both cell turnover and keratinization, the treatment can support improvement in visibly thickened or scaly skin.
Inflammation contributes to symptoms such as itching and irritation, while abnormal keratinization contributes to scaling. Crude coal tar application addresses both processes, so its potential benefit is not limited to reducing excess cell growth. This combined action helps explain its use in inflammatory and hyperproliferative disorders, including eczema, psoriasis, and seborrheic dermatitis.
The mixture can be incorporated into ointments, creams, shampoos, or bath preparations, allowing treatment to be adapted to different topical-care routines. Formulation affects how the product is applied and incorporated into broader skin care. Because odor, staining, irritation, and sunlight sensitivity may influence acceptability, selecting an appropriate preparation is an important part of clinical management.
Clinicians may include it when managing psoriasis, eczema, or seborrheic dermatitis, particularly when excessive epidermal growth, scaling, inflammation, or itching are relevant features. It is often used as one component of a broader skin-care regimen rather than as an isolated approach. The selected preparation and its use should reflect the treatment plan and patient guidance.
Patients should receive guidance about possible irritation, staining, odor, and increased sensitivity to sunlight. These effects can affect comfort, clothing, routine use, and tolerability, even when the preparation is therapeutically appropriate. Clear instructions about formulation, dosing, and practical precautions help balance the potential skin benefits with the disadvantages of treatment.
Evaluation should consider changes in scaling, itching, inflammation, and the excessive skin growth associated with the underlying disorder. Clinicians should also assess whether irritation, staining, odor, or sunlight sensitivity limits continued use. This balanced assessment helps determine whether the preparation is providing useful dermatological control within the patient’s overall skin-care regimen.
