Skin and hair are the outermost interfaces between the human body and the external environment with many microorganisms distributed. These body surface microorganisms have individual specificity and spatial temporal stability and can be transferred to the surface of other objects through contact, and can be easily found at the crime scene, which helps to construct the connection between the suspect and the crime scene. When the sample is degraded or the DNA quantity is too low to obtain sufficient human DNA evidence, the highly amplified copies of body surface microbiome analysis can be used as an adjunct to human DNA typing without affecting DNA extraction and typing, and provide useful information for narrowing the range of suspects. This paper reviews the forensic characteristics and analytical methods of body surface microbiome, the research progress on the application of body surface microbiome to forensic individual identification, and puts forward the challenges of applying body surface microbiome to forensic practice.

A niche in the context of microorganisms defines the specific ecological role or habitat inhabited by microbial species within an ecosystem. For the human commensal Malassezia, the skin surface is considered its primary niche, where it adapts to the skin environment by utilising lipids as its main carbon and energy source. However pathogenic characteristics of Malassezia include the production of allergens, immune modulation and excessive lipid utilisation, which result in several diseases such as pityriasis versicolor, seborrheic dermatitis, Malassezia folliculitis and atopic dermatitis.

Background: FcγRI, a pivotal cell surface receptor, is implicated in diverse immune responses and is ubiquitously expressed on numerous immune cells. However, its role in intracellular bacterial infections remains understudied.
Methods: Wild-type (WT) and FcγRI knockout (FcγRI-KO) mice were inoculated intranasally with a specific dose of C.

The mucosal surfaces of the body are the most vulnerable points for infection because they are lined by single or multiple layers of very active epithelial cells. The main protector of these cells is the mucus system generated by the specialized goblet cells secreting its main components, the gel-forming mucins. The organization of the mucus varies from an attached mucus that is impenetrable to bacteria in the large intestine to a nonattached, more penetrable mucus in the small intestine and airways.

Purpose: The present study is to explore the appropriate plantar support force for its effect on improving the collapse of the medial longitudinal arch with flexible flatfoot.
Methods: A finite element model with the plantar fascia attenuation was constructed simulating as flexible flatfoot. The appropriate plantar support force was evaluated.

The cervical uncinate process is a unique structure of the cervical spine that undergoes significant changes in its morphological characteristics with age, and these changes may be related to osteoporosis. This study aimed to observe the distribution of cancellous bone in the cervical uncinate process and its morphological features using micro-computed tomography (Micro-CT) to gain a deeper understanding of the morphological characteristics of the uncinate microstructure. We performed Micro-CT scans on 31 sets of C3-C7 vertebrae, a total of 155 intact bone samples, and subsequently used the measurement software with the Micro-CT system to obtain parameters related to the cancellous bone of the uncinate process.
