Summary: It has been shown that hair can accumulate and trap drugs, providing an indication of long-term exposure. Studying changes in the structure of hair and the effects of cosmetic treatments can help understand false positive results in drug testing and the impact of drugs on hair structure.

Summary: Lipidomics is a method for investigating the composition and function of lipids, usually using blood or tissue samples. Recently, hair has emerged as a potential sample type for identifying biomarkers in early disease stages and retrospectively documenting metabolic status. This study evaluated the lipid coverage of hair using different extraction methods and found that the applied lipidomics workflow improved hair lipid coverage, with several lipids reported for the first time. The study suggests that hair is a valuable matrix for clinical, forensic, and dermatological research.

Summary: This study investigates the associations between hair color, hair dyeing, hat wearing frequency, and the detection of cocaine and MDMA in hair samples. The results show that dyeing hair increases the odds of detecting cocaine and MDMA, while individuals with blonde hair generally have lower levels of cocaine detected. Additionally, frequent hat wearers have lower levels of MDMA detected.

Summary: This article discusses the issues of solar photovoltaic facilities in terms of siting and social acceptability. Current research mostly focuses on technical and economic criteria, while neglecting social factors. Incorporating siting criteria reflecting the interests of local people and how they interact with their environment can improve the developer's process.

Summary: Pregnancy brings about various physiological changes, with noticeable changes in the skin. Understanding these changes is important for physicians to differentiate anticipated normal physiological changes from potentially harmful ones and manage them accordingly. Further research is needed on the persistence of these changes after delivery.

Summary: The indication for liver resection for localized hepatic metastases from breast cancer remains controversial with heterogeneous reported data and weak scientific evidence. Surgery can be considered in cases where radical surgery is possible, sufficient liver tissue can be saved, and the interval between treatment of the primary site and diagnosis of hepatic metastases is appropriate.

Summary: Concerns and challenges exist in managing patients with acute or chronic exposure to psychostimulants during the perioperative period. Each subclass of psychostimulants has unique receptor specificity and different mechanisms that affect patient clinical presentation. Physiological and psychological effects of psychostimulants influence the action of anesthetic agents and analgesics used for pain management. Understanding the epidemiology, pharmacology, and perioperative implications of psychostimulant use is crucial for safe and effective perioperative management.

Summary: Clinical observations and experimental studies have shown that perifollicular nerves play a role in the growth, development, and physiological cycle of hair follicles. Recent advancements in immunohistochemistry and molecular biology techniques have led to more innovations in the study of follicular sympathetic nerves and norepinephrine's effects on hair follicle stem cells. This review emphasizes the progress in understanding the regulation of the sympathetic nervous system on hair follicle growth.

Summary: This research explores the use of eye tracking for sociological research on racial perception. The results show that participants pay the most attention to the targets' hair, especially when the targets have straight hair or are identified as Black/White mixed-race. The findings provide physiological evidence of the theory of multiracial dissection. The study concludes that eye tracking can help sociologists reveal subconscious tendencies and biases, which can be consciously addressed to reduce social disparities.

Summary: Hair testing for classic drugs of abuse offers longer detection times compared to urine analysis. Analyzing hair samples from patients with CocUD undergoing rTMS treatment can monitor changes in drug use patterns and clinical improvements. This suggests that hair testing could be a valuable tool in clinical settings for assessing the efficacy of therapeutic interventions like rTMS.

Summary: Fourier transform infrared (FT-IR) spectroscopy is widely used in forensic laboratories for various applications. In this study, we developed a new approach using machine-learning tools to enhance the selectivity of FT-IR spectroscopy and create classification models for the analysis of nail clippings. By analyzing ATR FT-IR spectra, we were able to successfully discriminate donors who do not drink alcohol from those who drink alcohol on a regular basis with high accuracy.

Summary: Aging is a complex process that affects physiological functions, including hair graying, thinning, and loss. These changes in hair can have a significant impact on an individual's self-esteem and mental health. Omics technologies have helped lead to the discovery of hair aging biomarkers and potential therapies.

Summary: Building on previous research, Godino and colleagues investigate the role of nuclear receptor RXRa in modulating gene transcription, neuronal activity, and behavior in response to cocaine. Their findings suggest that altering accumbens RXRa expression has significant effects on cocaine-induced behavioral responses.

Summary: Utility incentive programs are crucial for promoting energy efficiency in buildings, but they have been limited to single-component strategies. However, there is now a growing interest in developing multi-component system retrofits to achieve deeper energy savings. This paper presents the energy savings, demand reductions, and cost-effectiveness of 16 systems retrofit packages in the US, which are being used by utilities to inform incentive programs. The results show that packages with proven lighting and HVAC measures can provide significant energy and cost savings, and the choice of baseline for calculating savings has a substantial impact on program viability.
