BACKGROUND Foremost fine hairs in the frontal hairline region are critical in hair transplantation for hairline correction (HTHC) in women. However, there are few studies on a nonsurgical revisionary method for improving an unnatural foremost hairline with thick donor hairs resulting from a previous HTHC. OBJECTIVE To investigate the efficacy and safety of using a hair removal laser (HRL) sys...

The skin is like a canvas. Pigment distribution, skin appendages, skin ridges, etc. are arranged on the skin surface. The arrangement may be random but every now and then they form specific patterns. In some occasions, the specific arrangement is important for organism function or message display. In all occasions, these distinct arrays provide us with windows into the fundamental processes of ...

We report a fabrication process for constructing polymer surfaces with multiwalled carbon nanotube hairs, with strong nanometer-level adhesion forces that are 200 times higher than those observed for gecko foot-hairs.

Juvenile crickets suffer high rates of mortality by natural predators that they can detect using extremely sensitive air-sensing filiform hairs located on their cerci. Although a huge amount of knowledge has accumulated on the physiology, the neurobiology and the biomechanics of this sensory system in adults, the morphological and functional aspects of air sensing have not been as well studied ...

BACKGROUND Cutaneous human papillomavirus (HPV) infections seem to be associated with the onset of actinic keratosis (AK). This study compares the presence of cutaneous HPV types in eyebrow hairs to those in tissues of normal skin and skin lesions of 75 immunocompetent AK patients. METHODS Biopsies from AK lesions, normal skin and plucked eyebrow hairs were collected from each patient. DNA fr...

Bat wings are highly adaptive airfoils that enable demanding flight maneuvers, which are performed with astonishing robustness under turbulent conditions, and stability at slow flight velocities. The bat wing is sparsely covered with microscopically small, sensory hairs that are associated with tactile receptors. In a previous study we demonstrated that bat wing hairs are involved in sensing ai...

Many insects are able to sense their surrounding fluid environment through induced motion of their filiform hairs. The mechanism by which the insect can sense a wide range of input signals using the canopy of filiform hairs of different length and orientation is of great interest. Most of the previous filiform hair models have focused on a single, rigid hair in an idealized air field. We have d...

Baldness Hair loss Trichodynia Dr. Alfredo Rebora, Department of Dermatology, University of Genoa, Viale Benedeno XV, I-16132 Genova (Italy) No symptoms have ever been reported to accompany the development of baldness. There are patients, however, who, while complaining of hair loss, claim that their hair has become painful. We describe such discomfort and we propose the term trichodynia for it...

Membrane trafficking and cytoskeletal dynamics are important cellular processes that drive tip growth in root hairs. These processes interact with a multitude of signaling pathways that allow for the efficient transfer of information to specify the direction in which tip growth occurs. Here, we show that AGD1, a class I ADP ribosylation factor GTPase-activating protein, is important for maintai...

A new area operator was proposed to extract axes feature of hair impurity in mushroom semiproduct images. This operator was based on the local intensity comparison, and it had two advantages: 1) its outputs reached local maxima at the hair axes; 2) the accurate direction information of the hair axes could be derived by it. After the axes feature of the hairs was extracted using the proposed ope...
