DNA tensiometer reveals catch-bond detachment kinetics of kinesin-1, -2 and -3.

Bidirectional cargo transport by kinesin and dynein is essential for cell viability and defects are linked to neurodegenerative diseases. The competition between motors is described as a tug-of-war, and computational modeling suggests that the load-dependent off-rate is the strongest determinant of which motor 'wins'. Optical tweezer experiments find that the load-dependent detachment sensitivity of transport kinesins is kinesin-3 > kinesin-2 > kinesin-1.

Topical Moringa Formulations: An Emerging Skincare Ingredient.

Recently, the addition of moringa to skincare products has become a popular trend, especially in the natural beauty industry. It is being marketed for its intended moisturizing, antioxidant, and anti-aging properties; however, data are scarce demonstrating its clinical effects as well as standardized concentration, formula, source, and extraction methods. Skin specialists must be aware of this trendy ingredient, including its recent claims in marketing material and current evidence in the literature.

Role of Nesprin-2 and RanBP2 in BICD2-associated brain developmental disorders.

Bicaudal D2 (BICD2) is responsible for recruiting cytoplasmic dynein to diverse forms of subcellular cargo for their intracellular transport. Mutations in the human BICD2 gene have been found to cause an autosomal dominant form of spinal muscular atrophy (SMA-LED2), and brain developmental defects. Whether and how the latter mutations are related to roles we and others have identified for BICD2 in brain development remains little understood.

Body contouring for fat and muscle in aesthetics: Review and debate.

The recent demand for noninvasive fat reduction and muscle toning has generated the need for a variety of noninvasive body contouring devices, including cryolipolysis, radiofrequency, focused ultrasound, laser energy, and high intensity focused electromagnetic energy. Many of the recent technologies are still relatively new, and clinical trials are limited. There is also a lack of comparison between modalities, which makes it difficult for practitioners to select the best treatment option for patients.

Female genitourinary treatments in aesthetics.

Female genitourinary treatments in aesthetics utilize energy-based treatments and other noninvasive modalities. These include CO and Erbium YAG lasers, radiofrequency, high-intensity focused electromagnetic energy, hyaluronic acid injection, platelet-rich plasma, and silicone thread treatments with an objective to treat sexual dysfunction and symptoms of genitourinary syndrome associated with menopause, which include atrophic vaginitis, urinary incontinence, and vulvovaginal laxity that is characterized by vaginal dryness, thinning of the epithelium, laxity, prolapse, incontinence, dyspareunia, and increased bacterial infections. The body of evidence is growing for the use of these modalities to improve signs and symptoms of the genitourinary syndrome associated with menopause and sexual function, as well as for rejuvenating the appearance of the external female genitalia.
