The Complete Mitochondrial Genome and Phylogenetic Analysis of the Freshwater Shellfish (Bivalvia: Pharidae).

Razor clams, belonging to the Pharidae and Solenidae families, are ecologically and economically important; however, very little research has been conducted on the Pharidae family. The genus is a marine-derived freshwater lineage, and is a rare freshwater species of the Pharidae family. In order to understand the phylogenetic relationships of , we sequenced the mitochondrial genome of the genus , which is 16,262 bp in length and consists of 12 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), and 2 ribosomal RNA genes (rRNAs).

Predictive Values of Postoperative and Dynamic Changes of Inflammation Indexes in Survival of Patients with Resected Colorectal Cancer.

The aim of the present study was to evaluate the prognostic potential of postoperative scores of inflammation indexes and the dynamic changes of scores before and after tumor resection in colorectal cancer patients. The study included 516 colorectal cancer patients with primary colorectal tumor resection. Cox regression was applied to estimate the associations of postoperative and dynamic changes of inflammation indexes with progression-free survival and overall survival.

Threshold effects of moderately excessive fluoride exposure on children's health: A potential association between dental fluorosis and loss of excellent intelligence.

Background: Excessive fluoride exposure is associated with adverse health outcomes, but little is known of the effects of moderately chronic fluoride exposure on children's health.

Objectives: We conducted a cross-sectional study to explore the health impact of moderately excessive fluoride in drinking water.

Methods: We recruited 2886 resident children, aged 7 to 13 years, randomly from endemic and non-endemic fluorosis areas in Tianjin, China.

The predictive value of integrated inflammation scores in the survival of patients with resected hepatocellular carcinoma: A Retrospective Cohort Study.

Background: Evidence supports the predictive potential of inflammatory marker-derived scores (inflammation scores) and hepatitis B virus (HBV) infection on prognosis of patients with hepatocellular carcinoma (HCC). However, no study has longitudinally assessed the predictive values of inflammation scores combined with hepatitis B virus status on survival of these patients. Therefore, a study was designed to evaluate the prognostic capacity of preoperative, dynamic changes in integrated scores, through a combination of general inflammation scores and HBV infection status, on HCC patients undergoing tumor resection.
