Introduction: Currently, the mostly used classifications of androgenetic alopecia (AGA) only provide a macroscopic and subjective description of this disorder, without evaluating trichoscopic features.
Objectives: The aim of this study is to elaborate a graded live visual AGA severity scale including macroscopic and microscopic (trichoscopic) pictures, and to determine the most frequent trichoscopic characteristics associated to each grade.
Methods: A retrospective observational study was conducted on 122 patients (50 females and 72 males) affected by AGA. Macroscopic and trichoscopic photographs were taken at standardized scalp points.
Results: Each picture was ranked from AGA stage I to VII, according to Hamilton scale for men and Sinclair scale for women, and the most representative images of each severity degree were collected to produce a graded live visual scale. In males, 2 live visual scales, 1 for the anterior and 1 for posterior region of the scalp were created. In females, only 1 scale of the anterior region was realized. For each stage of severity, the corresponding trichoscopic parameters were statistically analyzed.
Conclusions: We realized new macroscopic and trichoscopic graded live visual scales for male and female patients affected by AGA, which could help physicians in giving an objective evaluation of the disease and in better managing it.

Background: Early child development sets the course for optimal outcomes across life. Increasing numbers of children worldwide are exposed to opioids in pregnancy and frequently live in environments associated with adverse developmental outcomes. Although multiple systematic reviews have been published in this area, they use different exposures and different types of outcomes.

Objectives: Thalamic hematoma patients present with diverse clinical conditions, and treatment approaches vary widely. Currently, the use of disposable portable endoscope surgery has been rapidly adopted in many hospitals, but outcomes can vary significantly. Surgical approaches and techniques for thalamic hematoma often reference those used for basal ganglia hemorrhage, but their effectiveness remains uncertain.

Many animals are capable of rapid dynamic colour change, which is particularly well represented in fishes. The proximate mechanisms of dynamic colour change in fishes are well understood; however, less attention has been given to understanding its ecological relevance. In this study, we investigate dynamic colour change in zebrafish () across multiple contexts, using a protocol to image the colouration of live fish without anaesthesia under standardized conditions.

Parental experiences can alter offspring phenotypes via transgenerational plasticity (TGP), which may prime offspring to adaptively respond to novel stressors, including novel predators. However, we know little about the types of sensory cues (e.g.

While mRNA imaging techniques are well-established, the development of effective methods for studying non-coding RNAs (ncRNAs) in living cells are still challenging but necessary, as they show a variety of functions and intracellular localizations, including participation in highly dynamic processes like phase-transition, which is still poorly studied in vivo. Addressing this issue, we tagged two exemplary ncRNAs with the fluorescent RNA (fRNA) Pepper.
