Abstract
The bromoalkane, 1-bromopropane (1-BP), may damage the reproductive system though oxidative stress, while the transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) plays an important role in regulating intracellular antioxidant levels against oxidative stress. This study explored the role of oxidative stress and the Nrf2 signaling pathway in mediating the reproductive toxicity of 1-BP using the ovarian carcinoma cell line OVCAR-3 as an in vitro model of the human ovary. OVCAR-3 cells were treated with 1, 5, 10 and 15 mM 1-BP. After 24 h, the cellular reactive oxygen species and malondialdehyde concentrations significantly increased, while the superoxide dismutase activity decreased; translocation of Nrf2 from the cytosol to the nucleus as well as downstream protein expression of Nrf2-regulated genes heme oxygenase-1 and Bcl-2 was inhibited. Apoptosis was also observed, accompanied by increased caspase-3 and caspase-9 activity. The antioxidant vitamin C alleviated 1-BP-induced apoptosis by inhibiting caspase activity activating the Nrf2 signaling pathway. These findings suggested that 1-BP induced oxidative stress and apoptosis in OVCAR-3 cells through inactivation of Nrf2 signaling.

JOURNAL OF APPLIED PHYCOLOGY 2016; 29:949-982. [PMID: 28458464 PMCID: PMC5387034 DOI: 10.1007/s10811-016-0974-5] [Citation(s) in RCA: 539] [Impact Index Per Article: 67.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/06/2016] [Revised: 09/25/2016] [Accepted: 09/26/2016] [Indexed: 05/21/2023]
Abstract
Global demand for macroalgal and microalgal foods is growing, and algae are increasingly being consumed for functional benefits beyond the traditional considerations of nutrition and health. There is substantial evidence for the health benefits of algal-derived food products, but there remain considerable challenges in quantifying these benefits, as well as possible adverse effects. First, there is a limited understanding of nutritional composition across algal species, geographical regions, and seasons, all of which can substantially affect their dietary value. The second issue is quantifying which fractions of algal foods are bioavailable to humans, and which factors influence how food constituents are released, ranging from food preparation through genetic differentiation in the gut microbiome. Third is understanding how algal nutritional and functional constituents interact in human metabolism. Superimposed considerations are the effects of harvesting, storage, and food processing techniques that can dramatically influence the potential nutritive value of algal-derived foods. We highlight this rapidly advancing area of algal science with a particular focus on the key research required to assess better the health benefits of an alga or algal product. There are rich opportunities for phycologists in this emerging field, requiring exciting new experimental and collaborative approaches.

Abstract
This review describes recent selected HPLC/MS methods for the determination of urinary mercapturates that are useful as noninvasive biomarkers in characterizing human exposure to electrophilic industrial chemicals in occupational and environmental studies. High-performance liquid chromatography/mass spectrometry is a sensitive and specific method for analysis of small molecules found in biological fluids. In this review, recent selected mercapturate quantification methods are summarized and specific cases are presented. The biological formation of mercapturates is introduced and their use as indicators of metabolic processing of reactive toxicants is discussed, as well as future trends and limitations in this area of research.

Abstract
Three metabolites of 1-bromopropane (1-BP) were measured in urine samples collected from 30 workers exposed to 1-BP at two facilities making furniture seat cushions and evaluated for use as biomarkers of exposure. The mercapturic acid metabolite, N-acetyl-S-(n-propyl)-l-cysteine (AcPrCys), 3-bromopropionic acid (3-BPA), and bromide ion levels (Br(-)) were quantitated for this evaluation. The high exposure group consisted of 13 workers employed as adhesive sprayers who assembled foam cushions using 1-BP containing spray adhesives and the low exposure group consisted of 17 non-sprayers, who worked in various jobs without spraying adhesives. All workers' urine voids were collected over the same 48 h period at work, and at home before bedtime, and upon awakening. Urinary AcPrCys and Br(-) levels were elevated in the sprayers compared to that of non-sprayers. Following HPLC-MS/MS analysis of mercapturic acid metabolite levels, 50 urine samples having the highest levels of AcPrCys were analyzed for 3-BPA. No 3-BPA was detected in any of the samples. The data collected from this study demonstrate that AcPrCys and Br(-) are effective biomarkers of 1-BP exposure, but 3-BPA is not.

Abstract
Dietary iodine and bromine intakes in Ukrainian subjects were estimated in relation to the health effects on inhabitants after the Chernobyl accident. Two hundred and eighty-six total diets were collected from twenty-five regions for Ukrainians by a duplicate portion study. Iodine and bromine were rapidly determined by inductively coupled plasma mass spectrometry after chemical separation. The range, median, and geometric mean of iodine intakes were 2.86-698, 44.7, and 48.1 microg per person per day, respectively. Those of bromine were 0.627-16.9, 2.97, and 2.92 mg per person per day, respectively. Daily intakes of both elements in Ukrainians were lower than previously reported values. The iodine intake in areas contaminated by the Chernobyl accident was lower than that in non-contaminated areas. The low iodine intake in both areas would be related to the high prevalence of goiters throughout the whole country. The low bromine intakes indicated Ukrainians were not exposed to bromine-containing foods.

Abstract
In this study, a high-performance liquid chromatography (HPLC) inductively coupled plasma (ICP) mass spectrometry (MS) method was developed intended for use in metabolism studies of bromine-containing drugs, administered to test animals (or test persons). As a case study, the method was applied to a new antituberculosis compound, the bromine-containing diarylquinoline R207910. A method has been proposed to overcome the incompatibilities between the high organic solvent content (45%CH3OH and 45% CH3CN) used in the reverse-phase liquid chromatography (LC) separation on one hand and the limitations of the ICP on the other hand. Therefore, several instrument modifications had to be made. For the introduction of the column effluent, a combination of a perfluoroalkoxy LC nebulizer with a PC(3) Peltier-cooled inlet system (operated at 2 degrees C) was used. Additionally, the standard injector tube (internal diameter 2 mm) was replaced by an injector tube with an internal diameter of 1 mm and to avoid carbon build-up on the interface cones and the torch, the nebulizer gas was admixed with 6% v/v of oxygen. After optimization of the method, HPLC-ICP-MS was applied for metabolite profiling of faeces samples after dosing of (14)C-radiolabelled R207910 to dogs and rats. To evaluate the method developed, the HPLC-ICP-MS results were compared with those of HPLC with UV spectrophotometric and (14)C radiochemical detection. As the HPLC-ICP-MS method gave rise to a higher selectivity than HPLC with UV detection and to a better detection limit (5 ng R207910) than the method with radiochemical detection (65 ng R207910), it can be concluded that ICP-MS can be used as a good alternative to the more traditional detection methods, even when a mobile phase with high organic solvent content has to be used in the LC separation.

Abstract
Inductively coupled plasma mass spectrometry (ICPMS) has been used to determine the rate and routes of excretion of bromine following the intraperitoneal administration (50 mg kg(-1)) of 2-, 3- and 4-bromobenzoic acids to male bile-duct-cannulated rats. Analysis of urine and bile for (79/81)Br using ICPMS showed that all three bromobenzoic acids were rapidly excreted (82-98%) within 48 h of dosing, primarily via the urine. High-performance liquid chromatography/inductively coupled plasma mass spectrometry (HPLC/ICPMS) was then used to obtain metabolite profiles for bile and urine. These profiles revealed that extensive metabolism had taken place, with the unchanged bromobenzoic acids forming a minor part of the total of compound-related material detected. Concomitant MS studies, supplemented by alkaline hydrolysis, enabled the identification of the major metabolite of all three of the bromobenzoic acids as a glycine conjugate. Ester glucuronide conjugates were also identified, but formed only a small proportion of total.
