[Landscape Pattern and Dynamic Change of Fractional Vegetation Cover in a Typical County in an Arid Region].

The dynamic change in fractional vegetation cover （FVC） in arid areas is an important basis for the development and evolution of desertification as well as critical component land desertification control. Using Hebukeser （also known as Hefeng）, a typical arid zone county, as the study area, we analyzed the changes in the ecological landscape pattern of vegetation with different coverages； investigated the dynamic changes of landscapes with different FVC from the perspectives of change frequency statistics, geocoding method, and migration of the center； and elaborated on the dynamic shift of various types of landscapes and the rule of migration of the center. The finding showed that： Over the course of the 20-year period, the county's average FVC increased from 18.

The growth and developmental of the myodural bridge and its associated structures in the human fetus.

Myodural bridge (MDB) is a dense connective tissue between suboccipital muscle and dura mater. However, there are few reports on the development and maturation of the human MDB. This study aims to explore the developmental relationship between suboccipital muscle and MDB.

Development, maturation, and growth of the myodural bridge within the posterior atlanto-axial interspace in the rat.

The myodural bridge (MDB) complex are fibrous bridges that functionally connect the spinal dura mater to the suboccipital musculature. Previously, we described the maturational sequence of the MDB within the posterior atlanto-occipital interspace of the rat. The present paper describes the morphology and developmental maturation of the MDB within the posterior atlanto-axial interspace of the rat.

Architecture of the cancellous bone in human proximal tibia based on P45 sectional plastinated specimens.

Purpose: To reveal differences in the pattern of trabecular architecture in the epiphysis and metaphysis of the proximal tibia.

Methods: The trabecular architecture of the proximal tibia was observed in 27 P45 plastinated knee specimens.

Results: In the medial and lateral condyles, under the articular cartilage surrounded by the medial or lateral meniscus, the cancellous bone is formed by thick and dense trabecular bands, which run longitudinally in the epiphysis and then pass through the epiphyseal line to terminate on the slanted cortex of the metaphysis.

Development of myodural bridge located within the atlanto-occipital interspace of rats.

The myodural bridge (MDB) is a dense connective tissue structure that connects the subocciptal musculature to the spinal dura mater. The purpose of this study was to clarify morphological evolution characteristics and compositional changes in the fibrous structures of MDB during its growth and development in the atlanto-occipital interspace. For this, histological sections from Sprague-Dawley (SD) rats (age, E17 to adulthood) were stained with Masson's Trichrome and Picrosirius Red.
