Response of resin canal area of with different ages to climate change in Taiyue Mountains, China.

To investigate the responses of resin canal area of with different ages to climate change, we analyzed the relationship between the resin canal area and climate factors from 1972 to 2017 in plantation at young age, middle age, near-mature, mature, and over-mature periods in Taiyue Mountains, Shanxi Province. The results showed that 55.7% to 75.

Differences in ecological resilience of radial growth between and after drought.

To understand the responses of radial growth to climatic factors and the differences in ecological resilience to drought between a heliophilous species and a shade species in mixed forests, we developed the tree-ring width chronologies of and in three mixed forests based on the samples collected from Toudaogou of Saihanba in Hebei, Ningwu County and Kelan County in Shanxi Province. We analyzed the correlation between climatic factors and various chronologies and examined the differences in resistance (), recovery (), and resilience () of and in response to drought stress. The results showed that the radial growth of and was negatively correlated with the mean and maximum air temperature from May to July in three mixed forests, and was positively correlated with the Palmer drought index (PDSI) from May to September.

Sex-specific differences in biomechanics among runners: A systematic review with meta-analysis.

Patellofemoral disorders are more common in female runners compared to their male counterparts. Differences in biomechanical characteristics between groups of runners could provide insight into the causes of higher rates of injury in female versus male runners, which would be useful to physical therapists and athletic trainers in development of individualized injury prevention programs. This review compares the differences in biomechanical characteristics between female and male runners.

Significance and relationship between infiltrating inflammatory cell and tumor angiogenesis in hepatocellular carcinoma tissues.

Aim: To investigate the relationship between infiltrating inflammatory cell and tumor angiogenesis in hepatocellular carcinoma (HCC) tissues and their clinicopathological features.

Methods: The paraffin-embedded specimens from 70 cases with HCC were stained using EliVision immunohistochemistry with mAbs against CD68, tryptase, and CD34. The counts of tumor-associated macrophage (TAM), mast cell (MC) and tumor microvessel (MV) were performed in the tissue sections.

[Expression of cyclins in hepatocellular carcinoma and its correlation to tumor cell apoptosis].

Background & Objective: Cyclins overexpress in various tumors, but its expression in hepatocellular carcinoma (HCC) and its correlation to cell proliferation and apoptosis are unclear. This study was to determine the expression of Cyclins, proliferating cell nuclear antigen (PCNA), and cell apoptosis in HCC, and to analyze their interrelations.

Methods: Tissue microarray technology and SP immunohistochemistry were used to detect expressions of Cyclins A, B1, D1, E, and PCNA in 122 specimens of HCC.
