Certain fungi and bacteria help orchid seeds germinate and plants grow better.

This study presents a method using liquid chromatography tandem mass spectrometry to quantify biotin in plasma and serum, and explores how high biotin intake can interfere with diagnostic immunoassays that utilize biotin-streptavidin technology, potentially leading to misdiagnosis of endocrine disorders.

This review analyzed clinical trial protocols for platelet-rich plasma preparation in hair loss treatment, finding inconsistent and insufficient reporting that complicates comparison and efficacy determination.

This study reported that pulverizing hair samples significantly improves the precision of testosterone measurement, with higher testosterone concentrations observed in men than in women.

This article reviews various aspects of shampoos, including preparation methods and commercial value, but reports no new experimental results, instead focusing on patents and product evaluation criteria.

This study found that ingenol mebutate treatment led to gene expression changes in actinic keratoses, with complete lesion clearance in 40% of patients and identified genetic markers potentially predicting treatment response.

This study found that cationic vesicles enhanced minoxidil skin retention and in vivo hair growth efficacy compared to other formulation types due to electrostatic interactions with the skin.

This study developed a stable nanoemulsion using ultrasonic vibrations and Tween 80 emulsifier, which can enhance the antibacterial activity and prolong the shelf life of food products, as well as be applicable in cosmetics and pharmaceuticals for oral and transdermal use.

This study found that a centrifugation protocol of 1300 rpm/246 g for 20 minutes followed by 1600 rpm/373 g for 20 minutes achieved the highest platelet yield in platelet-rich plasma.

This study explored the development of herbal hair gels using natural extracts like flaxseed and guava leaves, targeting the reduction of dandruff and regulation of hair loss through antimicrobial and anti-inflammatory properties, though specific results of efficacy are not reported.

This study found that a cimetidine 10% cream with sodium lauryl sulphate significantly increased drug diffusion through mouse skin and showed promise in treating warts in a preliminary clinical trial.

This study found that dyed chitin nanofibers maintain color and mechanical properties when reinforcing resins, allowing color addition and strength improvement while retaining transparency.

This study developed and validated a reliable method to measure finasteride levels in human plasma, which was successfully used to assess its pharmacokinetics after a 5 mg dose in healthy volunteers.

The researchers in this study conducted a comparative analysis of hair and body shampoos, finding notable physicochemical differences, such as body shampoos having lower surface tension and higher foam heights, while hair shampoos were more acidic, potentially to meet different biological and sensory needs.

This study suggests that artificial sebum L may serve as an effective substitute for human sebum in drug transport studies, due to its similar physicochemical properties.

This study found that alcoholic extracts of Cinchona succirubra, Dictamnus dasycarpus, Brassica juncea, and Sophora flavescens promoted hair growth in 5-week-old mice.

This study reports that using activated platelet-rich plasma releasate in the preparation of bioengineered hair follicle germs enhanced follicular gene expression and significantly improved hair regeneration in vitro.

This pilot study found no significant relationship between blood and hair mineral concentrations in generally healthy adults, though hair analysis may have potential for assessing long-term mineral trends.

In this study, the analysis of Ukraine's pharmaceutical market from 2020 to 2023 found a large variety of Vitamin D3 preparations, predominantly domestic and synthetic, with capsule forms being common; consumer surveys highlighted that doctor recommendations strongly influenced purchasing decisions.

In this study, the researchers formulated an herbal shampoo and found it exhibited excellent cleansing properties and foam stability, comparable to commercial shampoos, suggesting it as a safe and cost-effective alternative to marketed formulations.

In this study, variations in candle nut oil concentration (5%, 6%, 7%) impacted the characteristics and stability of a hair tonic nanoemulsion, influencing factors like droplet size, pH, and viscosity.

This study reported that men with more significant hair loss experience greater negative psychosocial effects, particularly noticeable in younger age groups.

This study presents an economical and user-friendly training module using common materials and goat skin to teach the steps of the strip method for hair follicle harvesting and implantation.
