https://www.readbyqxmd.com/read/29791144/environmental-risks-of-medium-chain-chlorinated-paraffins-mccps-a-review
#1
Juliane Glüge, Lena Schinkel, Konrad Hungerbuehler, Ronan Cariou, Christian Bogdal
Chlorinated paraffins are industrial chemicals which can be subdivided into short-chain (SCCP), medium-chain (MCCP), and long-chain (LCCP) chlorinated paraffins. The global production volumes of MCCPs are nowadays suspected to be much higher than those of S- and LCCPs, and the few available studies on the environmental occurrence of chlorinated paraffins report often higher MCCP than S- or LCCP concentrations in the environment. The present review focuses therefore on MCCPs specifically and provides a literature overview and a data analysis of the production volumes, PBT properties (persistence, bioaccumulation potential, and toxicity) and the worldwide measured concentrations of MCCP in environmental samples, biota, and humans...

Alan Hodgson
This paper presents a review and analysis of available data on background levels of Polonium-210 in urine. It was established that 819 measurements could be considered to correspond to natural background levels, excluding a large number of values identified by the original investigators as potentially due to an artificial source or due to recognised enhancement of dietary intake. Almost 550 measurements were extracted from studies reported in the literature; additional measurements were contributions of previously unpublished data by authors of more recent papers...

In the past two decades, a considerable amount of research has focused on the determination of the digestible (DE) and metabolizable energy (ME) contents of feed ingredients fed to swine. Compared with the DE and ME systems, the net energy (NE) system is assumed to be the most accurate estimate of the energy actually available to the animal. However, published data pertaining to the measured NE content of ingredients fed to growing pigs are limited. Therefore, the Feed Data Group at the Ministry of Agricultural Feed Industry Centre (MAFIC) located at China Agricultural University has evaluated the NE content of many ingredients using indirect calorimetry...

Epidemiological data from Lake Taihu showed significantly higher incidences of type 2 diabetes mellitus (T2DM) than in other areas of China. This may be related to the occurrence of a Microcystis bloom in Lake Taihu in the summer and autumn every year. The objective of this study is to investigate whether the contaminated water from the Microcystis bloom and the derivative pollutant microcystin-LR (MC-LR) can explain the higher incidences of T2DM. Healthy male mice were fed with water from different regions of Lake Taihu, and were either acutely or chronically exposed to MC-LR through oral administration or intraperitoneal injection...

Zhidong Gao, Kewei Jiang, Yingjiang Ye, Shan Wang
Gastric stump cancer(GSC) is defined as newly developed remnant stomach cancer following gastrectomy. This definition initially referred to carcinoma detected in the remnant stomach more than 5 years after the primary surgery for a benign disease. Subsequently, this timeframe was extended to 10 years after the primary surgery for a malignant disease. Recently, the concept of "carcinoma in the remnant stomach(CRS)" proposed by the Japanese Gastric Cancer Association was introduced in China. The new definition encompasses all carcinomas arising in the remnant stomach following gastrectomy, irrespective of the histology of the primary lesion, extent of resection, or reconstruction method...

INTRODUCTION: The symptoms of cow's milk protein allergy (CMPA) in infancy can be non-specific which may delay a correct diagnosis and cause adverse clinical outcomes. The diagnosis of non-IgE-mediated CMPA is particularly complex as it involves a 2 to 4 week elimination diet followed by oral food challenge (OFC). The Cow's Milk-related Symptom Score (CoMiSS) is a clinical resource for primary healthcare providers which aims to increase awareness of CMPA symptoms to facilitate an earlier diagnosis...

INTRODUCTION: Recent studies have suggested that there is a strong relationship between obstructive sleep apnea (OSA) and atrial fibrillation (AF). However, they have not identified whether treating OSA with continuous positive airway pressure (CPAP) might reduce rates of recurrent AF. OBJECTIVE: To investigate the recurrent risk of AF after catheter ablation among patients with OSA who did receive or did nor receive CPAP therapy. METHODS: A systematic review of PubMed, Embase, Medline, Cochrane library, China National Knowledge Infrastructure (CNKI) and Wan-fang databases was conducted to obtain relevant cohort studies and randomized controlled trials (RCTs)...
