Mangrove (Avicennia marina) forests in the Red Sea cost have great concern from environmental, biological, economic, and social points of view. Therefore, assessing water contamination in this ecosystem is worth to be investigated. Consequently, here we aimed to examine the levels of salinity, acidity, and the total content of Fe, Mn, Cu, Zn, Cd, Cr, Ni, and Pb in water samples collected from the upper, middle, and lower part of three mangrove lagoons (i.e., Al-Shuaiba, Yanbu, and Jeddah), Red Sea, Saudi Arabia. The total metal content (µg L-1) in water samples differed significantly among the studied areas and ranged from 286.2 to 4815.0 for Fe, 86.4-483.0 for Mn, 22.9-468.8 for Cu, 199.2-366.6 for Zn, 44.1-99.8 for Cd, 25.6-80.3 for Cr, 11.6-41.5 for Ni, and from 17.7 to 102.0 for Pb. The mean values of Cu, Zn, Cd, and Pb were higher than the WHO water quality standards for fisheries. Water samples in Yanbu were more contaminated and contained higher concentrations of all metals than Jeddah and Al-Shuaiba, due to the petrochemical industries in this industrial area. Our findings suggest that the high metal content in the water of these mangrove sites, particularly in Yanbu, should be considered due to the high potential environmental and human health risks in these ecosystems. These results may help for demonstrating effective approaches for the management of these lagoons. More studies will be carried out on the sediment and mangrove plants in this ecosystem.Consumption of geophagic materials can be detrimental to human health. These materials, which are harvested from the natural environment, can contain high concentrations of potentially harmful elements and minerals. In this study, mineralogical and geochemical investigation of geophagic rock materials consumed by the local population in Baringo town, in Kenya, was conducted to assess its possible health effects. Twelve representative samples were purchased from an open market in Baringo town for this investigation. Optical and scanning electron microscope as well as X-ray diffractometer was used to determine the mineralogy as well as the morphology of the minerals present in the studied samples. The material is composed of about 10 to 20% coarse to very coarse (0.38-3.00 mm) and semi-rounded to angular crystals of quartz, feldspars, and amphiboles, together with lithic fragments occurring in a fine-grained matrix. X-ray fluorescence and inductively coupled plasma mass spectrometry were used to determine the major and trace elements composition, respectively. The analyses show that elements such as Si, Fe, Mn, Al, Hg, Cr, Cd, and Pb are particularly above their recommended daily allowances. This study assumes 100% bioavailability of elements in the geophagic materials, in the absence of a bioaccessibility test. Therefore, the consumption of some of the revealed elements, based on this assumption, can be detrimental due to possible short- and/or long-term health effects. From a mineralogical point of view, the presence of feldspar and quartz with Moh's hardness of 6 and 7, respectively, and their coarse and angular morphology may cause damage to the dental enamel and the gastrointestinal tract. From a geochemical point of view, the high concentrations of the revealed chemical elements can have various health effects including, but not limited to neurotoxic effects, which are critical in prenatal exposure, neurodegenerative diseases, and cancer amongst other serious diseases.The concentrations, composition patterns, transport and fate of PAHs in semi-arid and arid soils such as in Central Asia are not well known. Such knowledge is required to manage the risk posed by these toxic chemicals to humans and ecosystems in these regions. To fill this knowledge gap, we determined the concentrations of 21 parent PAHs, 4,5-methylenephenanthrene, 6 alkylated PAHs, and biphenyl in soils from 11 sampling locations (0-10, 10-20 cm soil depths) along a 20-km transect downwind from the Almalyk metal mining and metallurgical industrial complex (Almalyk MMC), Uzbekistan. The concentrations of Σ29 PAHs and Σ16 US-EPA PAHs were 41-2670 ng g-1 and 29-1940 ng g-1, respectively. The highest concentration of Σ29 PAHs occurred in the immediate vicinity of the copper smelting factory of the Almalyk MMC. The concentrations in topsoil decreased substantially to a value of ≤ 200 ng g-1 (considered as background concentration) at ≥ 2 km away from the factory. Low molecular weight PAHs dominated the PAH mixtures at less contaminated sites and high molecular weight PAHs at the most contaminated site. buy VX-478 The concentration of Σ16 US-EPA PAHs did not exceed the precautionary values set by the soil quality guidelines of, e.g., Switzerland and Germany. Similarly, the benzo[a]pyrene equivalent concentration in soils near the Almalyk MMC did not exceed the value set by the Canadian guidelines for the protection of humans from carcinogenic PAHs in soils. Consequently, the cancer risk due to exposure to PAHs in these soils can be considered as low.
Bile acid diarrhoea or BAD is a common but little recognised cause of chronic diarrhoea. Few of these patients in China have been diagnosed due to a lack of diagnostic options.

To clarify the diagnostic value of serum fibroblast growth factor19 (FGF19) in BAD patients.

We reported on 60 chronic diarrhoea patients and 80 healthy volunteers (HV). Based on the 90th percentile levels of serum 7a-hydroxy-4-cholesten-3-one (C4) of HV, these patients were divided into BAD group (C4 ≥ 90th) and non-bile acid diarrhoea group (NBAD, C4 < 90th). Serum FGF19 in the two clinical groups and HV group were compared, as was distal ileum FGF19 in clinical groups. The diagnostic value of serum FGF19 for BAD was evaluated.

The 90th percentile of serum C4 in HV group was 65.87ng/ml. Serum FGF19 concentrations in BAD group (Median 69.28pg/ml; n = 23) were significantly lower than those in HV (Median 122.18pg/ml; n = 80) and NBAD (Median 129.57pg/ml; n = 29) groups. FGF19 mRNA of the distal ileum in BAD group, was lower than that in NBAD group, P = 0.002. The rate of FGF19 protein low expression of distal ileum in BAD and NBAD group were 78.3% and 48.3%, P = 0.027. Using an ROC curve, statistical analysis yielded a threshold FGF19 concentration of 117.3pg/ml (AUC, 0.906; 91.3% sensitivity, 79.3% specificity) for a clinical diagnosis of BAD.

Serum and distal ileum expression of FGF19 significantly decreased in BAD patients. The suggested clinical ranges for serum FGF19 < 117.3pg/ml has high sensitivity and specificity for BAD patients with a normal structural and histological ileum.
Serum and distal ileum expression of FGF19 significantly decreased in BAD patients. The suggested clinical ranges for serum FGF19  less then  117.3 pg/ml has high sensitivity and specificity for BAD patients with a normal structural and histological ileum.
