Mercury (Hg) is a chemical element that poses risks to human health due to its high toxicity and environmental persistence. We determined the total Hg (THg) and methyl Hg (MeHg) concentrations in hair samples from residents of the Demarcação District (Porto Velho, Rondônia) in the Brazilian Amazon, as well as in water and fish samples, to evaluate factors influencing human exposure. The average THg concentration in human hair was 7.86 ± 6.78 mg kg and it was significantly higher in men, with an increasing trend related to age. There was no significant difference between female age groups. Human exposure to Hg through water was negligible compared to fish consumption. The average weekly intake estimates in the community varied between 1.54 and 4.62 μg kg, substantially higher than the recommended limit. The fish species with the highest amounts safe for daily consumption were herbivores and detritivores. Our results contribute to an understanding of how exposure to Hg affects the health of riverside populations and provide insights for new research to develop methods to mitigate such exposure and thus improve the quality of life of Amazonian people.

Decorin (DCN) is a member of the small leucine-rich proteoglycan family within the extracellular matrix, playing a role in the growth and development of hair follicle (HF). Exosomes serve as significant mediators of intercellular communication and are involved in the cyclic regeneration of HF. Exosomes derived from dermal papilla cells (DPC-Exos) are essential for the cycling and regrowth of HF.

Millions of men and women suffer from alopecia, especially androgenic alopecia (AGA), which is considered the most common form of hair loss. The available treatments for hair loss include multiple approaches, with the most popular being synthetic drugs including minoxidil and finasteride, in addition to natural products. However, synthetic drugs have shown many undesirable side effects, on the contrary, the specifications of the commonly used natural drugs have not been reported in most of the previous studies, despite the high market preference for them.

A 63-year-old man, with no past medical history, presented with an asymptomatic, progressively evolving polypoid lesion for 2 years in the left ciliary region. Physical examination revealed an exophytic tumor lesion of firm consistency and lobulated surface, with regular and well-defined borders. It measured 2 cm in diameter, and had a brownish-violet coloration with whitish areas (Figure 1).

Coronavirus disease 2019 (COVID-19) can lead to persistent symptoms, sequelae, and other medical complications that may last for weeks or months after recovery. The aim of the study is to assess the prevalence and risk factors of long COVID-19 persisting for 2 years in Hainan Province, China, to aid in its recognition, prevention, and treatment. Between July and August 2022, 960 individuals with confirmed SARS-CoV-2 infection in Hainan, China, were recruited.
