This collection of reviews, edited by Ken Lukowiak and Janis Weeks, explores diverse sensory systems across species, including olfaction, echolocation, magnetoreception, and visual adaptations, without presenting new experimental results.

This study established a novel in vivo "whisker follicle microinjection assay" using mouse whiskers to evaluate hair growth and pigmentation effects of various chemicals and proteins, identifying minoxidil, ruxolitinib, and RSPO1 as growth promoters, while deoxyarbutin inhibited pigmentation and Nbl1 emerged as a growth inhibitor.

This study developed a hat-shaped device with wearable sensors to estimate scalp moisture content using machine learning, demonstrating that it can provide accurate measurements comparable to professional scalp analyzers without the need for high-cost equipment.

This study describes a gel-supported in vitro system for culturing skin samples that may effectively replace animal systems for toxicity testing, showing high correlation with in vivo skin toxicity measurements.

This study found that microplastics on the Lebanese Mediterranean coast transport various organic and inorganic pollutants, posing threats to marine organisms and potentially human health.

This study found that hair analysis is an effective non-invasive method for assessing metabolic fluctuations, showing stable advanced glycation end products levels that correlate with age and differ significantly between diabetic and non-diabetic rats.

This review discusses attempts to confirm low-dose effects in rodent endocrine studies and reports no findings; variability in control groups hinders demonstrating weak effects.

This study found that LC-MS/MS assays provided more reliable and precise steroid measurements in human serum compared to traditional immunoassays, particularly at lower concentrations.

This study confirmed that the diffusion of cortisol from blood is a biologically endogenous source of hair cortisol, correlating significantly with salivary cortisol levels in healthy humans.

This study suggests that increased use of anticancer drugs from 2004 to 2008 has led to higher environmental release, necessitating expanded monitoring and research on their ecotoxicological impacts.

In this study, researchers developed a sensitive assay to measure the inhibition of steroid 5-α reductase (5AR) by chemicals like finasteride and dutasteride, revealing species-specific differences in inhibitor efficacy between human and fish cell lines.

In this study, researchers reported that adult females approaching menopause in Canada generally had similar or lower blood concentrations of toxic, essential, and trace elements compared to their peers, but most participants showed zinc levels below the proposed adequacy threshold.

This study established a protocol using anti-steroid antibodies to differentially label epidermal cell contributors, suggesting potential applications in simplifying complex trace DNA mixtures before profiling.

This study reported a simple and validated gas chromatography method to accurately measure finasteride in tablets, showing equivalency to the official method with no significant differences.

This study determined that most elemental concentrations in Mexican medicinal plants were similar to agricultural products, with bromine being an exception.

The algae grew better and fixed nitrogen more efficiently when they worked together, using nitrogen and iron.

This study found that the K6/ODC transgenic mouse model is highly sensitive to identifying genotoxic carcinogens, showing 100% concordance with traditional rodent bioassays.

This review discusses the growth potential and business opportunities in biocosmetics, emphasizing the replacement of fossil-based ingredients with bio-based alternatives, but reports no new experimental findings.

This study identified over 40 phytochemical compounds in the leaves and flowers of Bituminaria bituminosa, predominantly glycosylated flavonoids from apigenin, using advanced chromatographic techniques.

CEC levels may be a useful marker for predicting prostate cancer progression.

This study reports a highly sensitive MEMS silicon-hair device that mimics hair follicle functions by detecting minimal forces and moments, including electrostatic attraction and surface tension of liquids.

This study developed a straightforward HPTLC method for detecting nicotine and cotinine in human plasma and urine, concluding that liquid-liquid extraction with methanol: chloroform: ammonia achieved optimal separation and is applicable for forensic analysis of lethal nicotine intoxication.

This study introduced a rapid rehydration approach for creating customizable, multifunctional hydrogel sensors, enabling precise detection of surface deformations and easy integration of layers, highlighting its potential for standardized and adaptable manufacturing of wearable devices.

This review highlights the importance of standardizing pre-analytical procedures for collecting and extracting samples from uncommon biological specimens like breast milk and sweat in clinical metabolomics, to enhance diagnostic and biomarker discovery efforts while minimizing contamination and bias.

This study aims to assess how daily life factors affect sleep patterns and describe individual sleep changes across the year, with results to be published in future research.

This study presents three spectrophotometric methods for determining finasteride in bulk and tablet forms, showing a linear relationship between absorbance and finasteride concentration.

This research found that certain inflammasome proteins, like caspase-1, ASC, IL-18, and IL-1β, were elevated in patients with aneurysmal subarachnoid hemorrhage (aSAH) compared to controls and suggested these proteins could serve as reliable biomarkers for inflammation, potentially predicting worse outcomes.

This study presents a new LC-MS/MS method that allows for more accurate detection of seven steroid hormones in human hair, enhancing the specificity and reliability of hormone analysis in psychoneuroendocrinological research.

This review discusses the potential of using human hair proteomics for non-invasive diagnostic and forensic applications but reports no new results; the authors highlight areas needing further research.
