Cloning and Stress-Induced Expression Analysis of Calmodulin in the Antarctic Alga Chlamydomonas sp. ICE-L.

Calmodulin (CaM) is a Ca-binding protein that plays a role in several Ca signaling pathways, which dynamically regulates the activities of hundreds of proteins. The ice alga Chlamydomonas sp. ICE-L, which has the ability to adapt to extreme polar conditions, is a crucial primary producer in Antarctic ecosystem.

Effects of ocean acidification on the physiological performance and carbon production of the Antarctic sea ice diatom Nitzschia sp. ICE-H.

Ocean acidification (OA) resulting from increasing atmospheric CO strongly influences marine ecosystems, particularly in the polar ocean due to greater CO solubility. Here, we grew the Antarctic sea ice diatom Nitzschia sp. ICE-H in a semicontinuous culture under low (~400ppm) and high (1000ppm) CO levels.

[Release and supplement of carbon, nitrogen and phosphorus from jellyfish (Nemopilema nomurai) decomposition in seawater].

Abstract: Jellyfish bloom has been increasing in Chinese seas and decomposition after jellyfish bloom has great influences on marine ecological environment. We conducted the incubation of Nemopilema nomurai decomposing to evaluate its effect on carbon, nitrogen and phosphorus recycling of water column by simulated experiments. The results showed that the processes of jellyfish decomposing represented a fast release of biogenic elements, and the release of carbon, nitrogen and phosphorus reached the maximum at the beginning of jellyfish decomposing.

Jellyfish (Cyanea nozakii) decomposition and its potential influence on marine environments studied via simulation experiments.

A growing body of evidence suggests that the jellyfish population in Chinese seas is increasing, and decomposition of jellyfish strongly influences the marine ecosystem. This study investigated the change in water quality during Cyanea nozakii decomposition using simulation experiments. The results demonstrated that the amount of dissolved nutrients released by jellyfish was greater than the amount of particulate nutrients.

[Causes of jellyfish blooms and their influence on marine environment].

Jellyfish blooms have damaged the normal composition and function of marine ecosystem and ecological environments, which have been one of the new marine ecological disasters. In this study, we summarized the possible inducements of jellyfish blooms, and the influences of jellyfish blooms on biogenic elements, dissolved oxygen, seawater acidity and biological community were discussed emphatically. The results showed that jellyfish blooms had a close contact with its physiological structure and life history, which had favorable characteristics including simple body struc- ture, rapid growth, thriving reproduction and short generation interval to tolerate harsh environment better.

[Treatment of enophthalmos after severe malar-maxillary complex fracture with titanium mesh and high density polyethylene (Medpor)].

Objective: To study the surgical management of enophthalmos after severe malar maxillary complex fracture.

Methods: The X-ray and CT examination were performed before operation to diagnose the orbital fracture and intraorbital tissue displacement. The fractured orbital rim was repositioned intraoperatively, followed by implantation of shaped titanium mesh to rebuild the orbital floor.

[Clinical research of angle-splitting ostectomy based on three dimensional computed tomography true-up technique].

Objective: To illustrate the morphological changes of mandible after angle-splitting ostectomy.

Methods: From January 2006 to April 2008, 10 cases had undergone mandibular angle-splitting ostectomy to reduce the width of the lower face. For each patient, CT datum of mandible at three stages (preoperative, immediate postoperative, 6 months postoperative) were collected.

[Comparative study of onlay bone graft absorption of outer cortex from mandible and cranium].

Objective: To investigate the value of application of mandibular outer cortex as bone graft by comparing its bone absorption with cranial outer cortex.

Methods: 8 minitype grown-up pigs at the age of 8 - 12 months underwent surgery of taking out the same size (2.5 cm x 1.

[The expression of M-phase promoting factor in salivary adenoid cystic carcinoma].

Purpose: To study the expression and clinical significance of M-phase promoting factor (MPF) in salivary adenoid cystic carcinoma (SACC).

Methods: The expression of MPF was investigated in 40 salivary adenoid cystic carcinomas and 40 normal salivary tissues by immunohistochemistry. The expression of MPF was detected in SACC-83 and SACC-LM with Western blot.

[The expression and activity of protein kinase A I in oral squamous cell carcinoma].

Purpose: To detect the expression and distribution of protein kinase A I (PKA I) in oral squamous cell carcinoma as well as its clinicalpathological significance.

Methods: The expression of PKA I was investigated in 40 oral squamous cell carcinomas and 15 normal tissues by immunohistochemistry. The activity of PKAI was detected in 20 human oral squamous cell carcinomas and adjacent normal tissues with Western blot.
