Therapeutic advances targeting tumor angiogenesis in pancreatic cancer: Current dilemmas and future directions.

Pancreatic cancer (PC) is one of the most lethal malignancies, which is generally resistant to various treatments. Tumor angiogenesis is deemed to be a pivotal rate-determining step for tumor growth and metastasis. Therefore, anti-angiogenetic therapy is a rational strategy to treat various cancers.

[Micro-Raman Spectral Characteristics and Implication of FeS2 from Metamorphic Belt between Coal and Intrusion in Wolonghu Coal Mine of Anhui Province, China].

Some FeS2 samples among metamorphic belt between coal and intrusion from Wolonghu mine in the north of Anhui Province were retrieved to characterize the signature of Raman Spectral. The results show that, all Raman data of different samples can be divided into 3 types as Ⅰ, Ⅱ and Ⅲ according to distinct differences of in Raman mode (M), Raman shift (Δν) and scattering intensity (Ⅰ). There are five strong scattering modes including high value Eg (1.

Micro-Raman spectral characteristics and implication of FeS2 from Augen granites in west of Guangdong.

Some FeS2 samples among Augen granite from Guanshanzhang mass in the west of Guangdong Province were retrieved to characterize the spectral signature of Raman. The results show that three distinct scattering modes active of Fe-[S2]2- Liberational Motion (Eg), Fe-[S2]2- Stretching Motion (Ag) and S--S Stretching Motion (Tg) are observed from all samples. Detailed analyses indicate that Raman shift (Δυ), Modes intensity (I) and full width at half maximum (FWHM) are different between each type pyrite.

[Spectral characteristics and implication of granite from pozaiying molybdenite deposits in west of Guangdong].

Some granite samples from Pozaiying molybdenite deposits in the west of Guangdong were retrieved to characterize the spectral signature of XRD, FT-NIR and Raman. The results show that compared to the Porphyry granite and granite in the far zone, the signal of XRD and Raman of granite in near zone is weaker while the signal of FT-NIR is stronger. The authors' analyses indicate that the FWHM of quartz (101) peak in XRD, Sericite peak (4 529 cm(-1)) in FT-NIR and quartz peak in Raman shift from the latter are higher than those of former two.

[Root system distribution and biomechanical characteristics of Bambusa oldhami].

To determine the mechanism of soil stabilizing through Bambusa oldhami root system, the vertical distribution of B. oldhami root system in soil was investigated, and the tensile strength of individual root and soil shear strength were measured in B. oldhami forest.

[Chemical forms and ecological effect of soil Mn in liver cancer's high incidence area in Zhu-jiang River Delta, China].

The samples of surface soil, deep soil, and vegetables were collected from the liver cancer's high- and low incidence areas in Zhujiang River Delta to study the relationships between soil Mn forms and vegetables' Mn enrichment. The results showed that the soil Mn in study area was mainly derived from parent materials, and rarely come from human activities. The average soil Mn content in liver cancer's high incidence area was 577.
