[Ecological and Health Risks of Trace Heavy Metals in Atmospheric PM Collected in Wuxiang Town, Shanxi Province].

The pollution of atmospheric PM and ambient air quality were investigated in Wuxiang Town, Shanxi Province, China, and the ecological and health risks of the trace heavy metals in PM were analyzed. The PM samples were collected every day using a medium-volume PM sampler in autumn (from Oct. 22 to Nov.

Descriptions of immature stages of (Maulik) (Coleoptera, Chrysomelidae, Cassidinae, Cryptonychini).

(Maulik, 1921), a hispid that damages several species of palm trees, was introduced accidently into China in 2001. The egg, larva, prepupa and pupa of are illustrated and described in detail and compared with another invasive species, (Gestro, 1885); the scanning electron micrographs of the head capsule, antenna, maxilla, labium and lateral scoli are provided, as well as photos of body of all larval instars and pupa. It is the second description of immature stages in the genus Chapuis.

Luminescence enhancement of CaF:Nd nanoparticles in the second near-infrared window for in vivo imaging through Y doping.

In vivo luminescent imaging in the second biological window (1000-1400 nm, NIR-II) has attracted increasing attention since it can provide high sensitivity to deep tissue in vivo imaging. Herein, we synthesized approximately 10-15 nm-sized NIR-II luminescent nanoparticles (CaF:Nd NPs). Furthermore, co-doped Y was utilized to enhance the NIR-II luminescence of the CaF:Nd NPs via breaking the aggregation of Nd.

Five-nanometer ZnSnO:Cr,Eu ultra-small nanoparticles as new near infrared-emitting persistent luminescent nanoprobes for cellular and deep tissue imaging at 800 nm.

Until now, the afterglow emissions of most developed near infrared (NIR)-emitting persistent luminescent nanoparticles (NPLNPs) were located at approximately 700 nm, at the edge of the first tissue transparency window (from 650 to 900 nm), which resulted in relatively low tissue penetration and signal-to-noise ratio (SNR) for in vivo imaging. Herein, 5 nm ZnSnO:Cr,Eu (ZSO) NPLNPs with NIR afterglow emission at 800 nm are synthesized via a direct aqueous-phase synthesis method. The longer NIR afterglow emission of ZSO NPLNPs can easily penetrate approximately 3 cm of pork tissue.

Molecular cloning and expression of the vitellogenin gene and its correlation with ovarian development in an invasive pest Octodonta nipae on two host plants.

There is an ongoing relationship between host plants and herbivores. The nutrient substances and secondary compounds found in the host plant can not only impact the growth and development process of herbivores, but, more importantly, may also affect their survival and reproductive fitness. Vitellogenesis is the core process of reproductive regulation and is generally considered as a reliable indicator for evaluating the degree of ovarian development in females.

Prognostic Value of Lymph Node Ratio in Locally Advanced Rectal Cancer Patients After Preoperative Chemoradiotherapy Followed by Total Mesorectal Excision.

Although the absolute number of positive lymph nodes (LNs) has been established as 1 of the most important prognostic factors in rectal cancers, many researchers have proposed that the lymph node ratio (LNR) may have better predicted outcomes. We conducted a retrospective study to compare the predictive ability of LNR and ypN category in rectal cancer. A total of 264 locally advanced rectal cancer (LARC) patients who underwent preoperative chemoradiotherapy (CRT) followed by total mesorectal excision (TME) between 2005 and 2012 were reviewed.

[A procedure to assist achievement of total mesorectal excision through the extending intersphincteric plane].

Objective: To investigate the value of assisted achievement total mesorectal excision (TME) through the extending intersphincteric plane.

Methods: From February 2006 to April 2010, 65 patients with low rectal cancer underwent assisted implementing TME through the extending intersphincteric plane under direct vision and achieved sphincter preservation. The clinical data was summarized and analyzed retrospectively.
