This pilot study explored a new method using laser-capture microdissection and 16S rRNA gene sequencing to analyze the human scalp hair follicle microbiome more accurately, revealing region-specific variations in microbial diversity and abundance.

This study concluded that standard decontamination procedures do not fully remove external contamination from post mortem hair specimens, which complicates using hair analysis to assess long-term drug exposure.

In this study, human hair-carboxymethylated protein analysis showed that weathering for over 2.5 years can obscure electrophoretic patterns, while cosmetic treatments did not cause significant changes.

Researchers developed a method to detect hormone-blocking drugs in wastewater and found them in Beijing's sewage, suggesting they can survive sewage treatment.

This study hypothesizes that a mummified 19th Century girl in San Francisco died of severe undernourishment potentially due to a bacterial-borne disease, highlighting historical health challenges mitigated by modern sanitation and medicine.

In this study, NIH hairless mice showed increased susceptibility to Listeria monocytogenes infection compared to NIH mice, potentially due to differences in gut microbiota and monocyte levels.

This study found that horses with inflammatory skin diseases had a higher prevalence of surface cocci and fungal poroconidia compared to those with healthy skin.

This study reports that the Swedish newborn screening program for phenylketonuria, galactosaemia, and biotinidase deficiency is effective, with high sensitivity and specificity, and lower false positive rates compared to other countries, while genetic variants impact detection and incidence patterns in Sweden.

This study found that oral administration of Thauera sp. strain GDN1 reduced serum androgen levels in male mice by about 50%, suggesting its potential as a probiotic treatment for hyperandrogenism.

In this case report, a persistent skin infection in a Bullykutta dog was resolved with a 10-day treatment regimen of Sulphamethoxazole, trimethoprim, omega fatty acids, and topical therapy after previous treatments failed.

In this study, monoclonal antibody B72.3 showed selective immunoreactivity to specific types of normal canine epithelial cells, primarily those involved in mucin production.

In this study, the ethanol extract of Tridax procumbens leaves exhibited antimicrobial activity against both Gram-positive and Gram-negative bacteria, with specific active compounds identified through GC-MS analysis that may contribute to its therapeutic potential.

This study found that palmoplantar pustulosis patients exhibited oral dysbiosis, particularly among those with pustulotic arthro-osteosis, as compared to healthy controls.

Gut microbiota influences the development of alopecia areata.

This review highlights the potential analytic interference of high-dose biotin with immunochemical tests, which may lead to diagnostic errors and suggests pausing biotin consumption before laboratory testing.

In this study, researchers developed an herbal shampoo using extracts from multiple plants and observed that specific combinations effectively inhibited bacteria like Pseudomonas aeruginosa and Staphylococcus species, with certain formulations also being well-received by consumers for color and overall satisfaction.

In this study, the 40-MBR system was shown to enhance drug-screening efficiency by providing reliable, real-time monitoring of cell conditions in 3-D cultures compared to traditional methods.

This study found that the gut microbiota in alopecia areata patients showed distinct dysbiosis, with an overrepresentation of Firmicutes and underrepresentation of Bacteroides, aligning with patterns seen in other autoimmune disorders.

Certain gut bacteria may protect against hair loss, while others may increase the risk.

This study determined the broad class and molecular species of glycerophospholipids in Eastern red bat sebum, highlighting differences from previous bat lung surfactant studies.

This pilot study found that night shift workers showed fewer signs of wrinkle formation compared to day workers, but there were no significant differences in DNA amplification or collagen percentage.

This review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.

This study using high-performance liquid chromatography reported that mice with more diverse gut microbiota had higher levels of specific compounds in hair compared to those with less diversity, with stress affecting certain plasma levels.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

This study reports that citrulline, uniquely found in the inner root sheath of hair follicles, can be specifically detected with the carbamido diacetyl reaction, resulting in a bright orange color.

In this study, the researchers used Mendelian randomization to suggest a potential causal link between various gut microbiota and alopecia areata, finding that certain bacteria like Butyricimonas and Phascolarctobacterium may have protective effects, whereas others like Ruminococcaceae UCG003 might increase risk.

This experimental study found that leaf extracts from Averrhoa bilimbi and Muntingia calabura significantly inhibited the growth of Staphylococcus aureus, with M. calabura demonstrating stronger antibacterial activity, suggesting potential for acne treatment.

This study developed and validated a sensitive liquid chromatography–mass spectrometry method to measure aristolochic acid‐I in rat plasma, successfully applying it to pharmacokinetic research.

This article discusses the importance of considering biotinidase deficiency in differential diagnosis for patients with certain neurological and dermatological symptoms, as timely treatment with biotin is crucial to prevent severe consequences.

This study found that a significant number of boreal woodland caribou in NE British Columbia showed symptoms of trace mineral deficiencies and exposure to various pathogens, with substantial winter tick infestations affecting a majority of individuals.
