Hair shaft diameter is one of the most important factors for the outcome of follicular unit extraction (FUE) surgery. In fact, the hair shaft is elliptical. Therefore, it has a long and short axis. Many hair transplantation surgeons use manual micrometer caliper for gauging hair diameter and use the results in the management of recipient and donor area.
In this study, we aimed to identify the dependability of micrometer caliper and also the hair diameter diversity pattern in the donor area.
Two hundred and seventy hairs were collected from three males with androgenetic alopecia. Hair samples were obtained from the 1cm
boxes from superior to inferior at the mid-point of temporal, parietal, and occipital donor areas. The diameter of each hair was measured both with a micrometer caliper and scanning electron microscopy (SEM).
Average diameter measured by scanning electron microscopy was 83.01µm for the long axis and 51.51µm for the short axis. The average value for the micrometer caliper measurement was 53.32µm. Comparison of micrometer caliper results with the short-axis measurements of SEM revealed a strong significant correlation. The hair diameters from superior, middle, and inferior boxes revealed a tendency to decrease toward the inferior regions.
A manual micrometer caliper is a dependable tool for planning FUE surgery, and it measures the short axis of the elliptical hair shaft. Hair diameter tends to decrease toward the inferior regions of the donor area.

The assignment of sequences to genus or species level is critical for biodiversity surveys and biomonitoring, but it is particularly challenging as researchers must select the approach that best recovers information on species composition. This study evaluates the performance and accuracy of seven methods in recovering the species composition of mock communities by using COI barcode fragments. The mock communities varied in species number and specimen abundance, while upstream molecular and bioinformatic variables were held constant, and using a set of COI fragments. We evaluated the impact of parameter optimization on the quality of the predictions. Our results indicate that BLAST top hit competes well with more complex approaches if optimized for the mock community under study. For example, the two machine learning methods that were benchmarked proved more sensitive to reference database heterogeneity and completeness than methods based on sequence similarity. The accuracy of assignments was impacted by both species and specimen counts (query compositional heterogeneity) which ultimately influence the selection of appropriate software. We urge researchers to (i) use realistic mock communities to allow optimization of parameters, regardless of the taxonomic assignment method employed; (ii) carefully choose and curate the reference databases including completeness; and (iii) use QIIME, BLAST or LCA methods, in conjunction with parameter tuning to better assign taxonomy to diverse communities, especially when information on species diversity is lacking for the area under study.
Coronavirus disease 2019 (COVID-19) emerged in China, leading to worldwide morbidity and mortality, including depression and anxiety. As the pandemic spread throughout Italy, mental health concerns increased for people with cystic fibrosis (pwCF), who are at greater risk. The aim was to pilot a Telehealth Psychological Support Intervention for pwCF and caregivers to reduce stress, depression, and anxiety during the lockdown in Italy in March 2020.
This intervention utilized cognitive behavioral skills (e.g., cognitive reframing). Participants included 16 pwCF and 14 parents, who completed four individual telehealth sessions with a psychologist. Stress ratings, Patient Health Questionnaire and General Anxiety Disorder, PHQ-8 and GAD-7, were completed, in addition to Feasibility and Satisfaction ratings.
Ratings of stress significantly decreased from pre- to post-testing for pwCF (paired t(14) = -4.06, p < .01) and parents (paired t = -5.2, p < .001). A large percentage of both groups scored in the as ongoing. This feasible, satisfactory intervention was effective for improving mental health.The melatonin hormone secreted by the pineal gland, is involved in physiological functions such as growth and maturation, circadian cycles, and biological activities including antioxidants, anti-tumor, and anti-ischemia. click here Melatonin not only interacts with proteins but also has functional effects on regulatory RNAs such as long non-coding RNAs (lncRNAs) and micro RNAs (miRNAs). In this study, we overview various physiological and pathological conditions affecting melatonin through lncRNA and miRNA. The information compiled herein will serve as a solid foundation to formulate ideas for future mechanistic studies on melatonin. It will also provide a chance to more clarify the emerging functions of the non-coding transcriptome.The design of optimal guide RNA (gRNA) sequences for CRISPR systems is challenged by the need to achieve highly efficient editing at the desired location (on-target editing) with minimal editing at unintended locations (off-target editing). Although laboratory validation should ideally be used to detect off-target activity, computational predictions are almost always preferred in practice due to their speed and low cost. Several studies have therefore explored gRNA-DNA interactions in order to understand how CRISPR complexes select their genomic targets. CHOPCHOP (https//chopchop.cbu.uib.no/) leverages these developments to build a user-friendly web interface that helps users design optimal gRNAs. CHOPCHOP supports a wide range of CRISPR applications, including gene knock-out, sequence knock-in, and RNA knock-down. Furthermore, CHOPCHOP offers visualization that enables an informed choice of gRNAs and supports experimental validation. In these protocols, we describe the best practices for gRNA design using CHOPCHOP.
