Male androgenetic alopecia.

Male androgenetic alopecia (MAA) is quite common and worsens with age, with a significant impact on quality of life, and is increasingly a reason for consultation with a dermatologist. The etiopathogenesis of MAA is multifactorial and genetic and hormonal influences stand out. MAA starts with the process of follicular miniaturization in diverse phenotypic patterns.

Alopecia Induced by Poly-L-Lactic Acid Injection.

Cosmetic procedures carry inherent risks of adverse events. Though rarely reported, transient and permanent alopecia are potential complications of these procedures. We report the case of a 35-year-old woman who developed pain and patches of nonscarring alopecia with erythema and edema following aesthetic application of poly-L-lactic acid (PLLA) on the face and along the frontal hairline.

The "Survival Pending Revolution" COVID-19 vaccination campaign: an example of critical communication theory in action.

Introduction: We carried out a two-phase, qualitative evaluation of a novel public health campaign to promote COVID-19 vaccination among youth and young adults of color (YOC), called Survival Pending Revolution. The campaign, commissioned by California's Department of Public Health, was created by YOC spoken word artists, under the direction of the organization, Youth Speaks.

Methods: In phase 1, we describe the communication attributes of the campaign's nine video-poems, coded the content of the pieces, and applied thematic analysis to describe the themes conveyed.

Reasons for and consequences of tooth loss in adults and elderly people in Brazil: a qualitative metasynthesis.

The objective was to analyze and systematize evidence reported in qualitative studies on the reasons and consequences of tooth loss in adults and elderly people in Brazil. A systematic review of the literature on qualitative research methods and a meta synthesis of the results were performed. The study population consisted of adults over 18 years of age and elderly people in Brazil.

Impact of an Arts-based Public Health Literacy Program Delivered Online to High School Students during the COVID-19 Pandemic.

The COVID-19 pandemic, coupled with the domestic socio-political unrest of 2020, provides a critical opportunity to reframe how we engage with youth around health and disease risk. (TBP), a spoken word, arts-based public health literacy campaign, uses a social justice and racial equity frame to activate youth around social determinants of health, including salient topics such as type 2 diabetes, COVID-19, climate change, and police violence. This quasi-experimental study determined the impact of providing an online adaptation of TBP during the COVID-19 pandemic to urban, low-income, diverse high school students (3 intervention schools assigned to receive TBP-based spoken word program; 3 comparison schools received a non-health focused spoken word program).

Seeing "The Bigger Picture:" Impact of an Arts-Focused Type 2 Diabetes Education Program in High Schools.

Traditional health education efforts rarely align with youth social justice values. The Bigger Picture (TBP), a spoken word arts campaign, leverages a social justice approach to activate youth around the social determinants of type 2 diabetes (T2D). This quasi-experimental study examines the impact of embedding TBP in urban, low-income high schools (3 intervention schools received TBP; 3 comparison schools received a non-health related spoken word program) with respect to (1) health-related mind-sets and expectations; (2) sense of belonging; and (3) civic engagement among youth.

Biochemical and Structural Analysis of Substrate Specificity of a Phenylalanine Ammonia-Lyase.

Phenylalanine ammonia-lyase (PAL) is the first enzyme of the general phenylpropanoid pathway catalyzing the nonoxidative elimination of ammonia from l-phenylalanine to give -cinnamate. In monocots, PAL also displays tyrosine ammonia lyase (TAL) activity, leading to the formation of -coumaric acid. The catalytic mechanism and substrate specificity of a major PAL from sorghum (; SbPAL1), a strategic plant for bioenergy production, were deduced from crystal structures, molecular docking, site-directed mutagenesis, and kinetic and thermodynamic analyses.
