CONTEXT Platelet-rich plasma (PRP) therapy is finding importance in aesthetic medicine. AIM The objective of this study was to study efficacy of PRP therapy in follicular unit extraction (FUE) hair transplant. MATERIALS AND METHODS It is a single-blind, prospective randomised study on 40 FUE hair transplant subjects, allocated in two groups (PRP and non-PRP) alternately. PRP was injected in...

Roots reinforce soil by acting as pins, dissipating shear stresses and anchoring the in place. By protruding into binding to particles, root hairs increase root-soil contact aid anchorage. However, it is not yet known whether this ability anchor roots affects system’s soil. Using a laboratory box shearing rig, study explores affect resistance. The force required columns permeated with lacking (...

Hair restoration is a highly sophisticated subspecialty that offers significant relief to patients with hair loss. An improved understanding of the aesthetics of hair loss and cosmetic hair restoration, hair anatomy and physiology, and the development of microvascular surgical instrumentation has revolutionized the approach to surgical hair restoration since the original description. Additional...

Detection of recent natural selection is a challenging problem in population genetics. Here we introduce the singleton density score (SDS), a method to infer very recent changes in allele frequencies from contemporary genome sequences. Applied to data from the UK10K Project, SDS reflects allele frequency changes in the ancestors of modern Britons during the past ~2000 to 3000 years. We see stro...

DNA-based capture-mark-recapture (CMR) techniques are commonly used to obtain population parameters of black bears (Ursus americanus) in rural and wildland landscapes; however, these techniques have not been implemented in urban clusters (i.e., 2,500 to 50,000 residents). Black bears can readily habituate to urban clusters, and wildlife managers need to monitor and manage these urban bear popul...

BACKGROUND The influence of systemic comorbidities on the success of scalp cooling during chemotherapy (CT) is widely unexplored. Comorbidities often require additional medication which itself can occasionally cause alopecia. This study investigates the influence of selected parameters on the efficacy of scalp cooling for the prevention of CT-induced alopecia. PATIENTS AND METHODS 226 cancer ...

We consider the task of predicting various traits of a person given an image of their face. We estimate both objective traits, such as gender, ethnicity and hair-color; as well as subjective traits, such as the emotion a person expresses or whether he is humorous or attractive. For sizeable experimentation, we contribute a new Face Attributes Dataset (FAD), having roughly 200,000 attribute labe...

Female pattern hair loss (FPHL) is the most common hair loss disorder in women. Initial signs may develop during teenage years leading to a progressive hair loss with a characteristic pattern distribution. The condition is characterized by progressive replacement of terminal hair follicles over the frontal and vertex regions by miniaturized follicles, that leads progressively to a visible reduc...

Experiments utilizing the Looptail mutant mouse, which harbors a missense mutation in the vangl2 gene, have been essential for studies of planar polarity and linking the function of the core planar cell polarity proteins to other developmental signals. Originally described as having dominant phenotypic traits, the molecular interactions underlying the Looptail mutant phenotype are unclear becau...

This study evaluated the resistance of cattle of different genetic groups to the tick Rhipicephalus microplus and the relationship with traits of the animals' hair and coat. Cows of the Senepol×Nelore (SN), Angus×Nelore (AN) and Nelore (NX) genetic groups were submitted to four consecutive artificial infestations, at 14-day intervals, each one with approximately 20,000 tick larvae placed on the...
