Green Chemistry Is The Path To Chemical Safety

Co-authored by Glynis Lough On June 22nd, the Frank R. Lautenberg Chemical Safety for the 21st Century Act was signed into law, bringing the first legislative reform to chemical management regulation in 40 years! From car seats to zippers, nearly every product in and out of the home has the potential to change because of this bill - meaning your favorite toy or cooking pan could be reformulated because chemicals toxic to human health are used in the production.  And the bill also includes special protections for women's and children's health. Sound great?  Sort of.  The reality of the bill is that it's a mixed bag - only twenty chemicals of the thousands and thousands that are actually used in consumer goods are required to be tested per year, and there's a 64,000 backlog - but with increased authority, the Environmental Protection Agency (EPA) can prevent new problems from entering the market. That means that real effort is needed to make this bill more than just public relations. To be sure, there are some good things in this bill, such as setting new safety standards for chemicals with ties to cancer, mental health, and infertility and allowing the Environmental Protection Agency (EPA) to obtain more information about a chemical before approving its use. We need more action to pollute less. What this really means is that we need to find other ways to protect people and the environment from the chemicals that we routinely use, like dry cleaning ...

Abstract Natural medicinal substances (NMS) have great inconsistency due to chemical variability, seriously limiting their development as therapeutics. Here, we chose toad venom with anti-tumor activities as a model and developed a pipeline of metabolomics-based screening and quality consistency control (MSQCC) as one potential solution to this long-standing problem. Our study firstly exemplified the power of the co-correlation screen of metabolomic and biological profiles of 180 fractions prepared from natural heterogeneous venom samples, to identify a series of bufadinolides as quality control markers for cancer...

Paeoniflorin inhibits IL-1β-induced MMP secretion via the NF-κB pathway in chondrocytes. Exp Ther Med. 2018 Aug;16(2):1513-1519 Authors: Hu PF, Sun FF, Jiang LF, Bao JP, Wu LD Abstract Paeoniflorin serves important cellular roles, exerting anti-cancer, anti-inflammatory and anti-pulmonary fibrosis effects and possesses immune-modulatory properties. However, the exact role of paeoniflorin in the pathogenesis of osteoarthritis (OA) remains unclear. The aim of the present study was to investigate the effects of paeoniflorin on articular surfaces in vitro. Rat chondrocytes were cultured in vitro...

Authors: Zhang M, Liu J, Li M, Zhang S, Lu Y, Liang Y, Zhao K, Li Y Abstract Glioblastoma multiforme (GBM) is a malignant tumor caused by complex pathological mechanisms, and is characterized by a high rate of cancer-related mortality and poor patient prognosis. Overgrowth of cancer cells, which results from the inhibition of cell apoptosis and/or the promotion of cell proliferation, leads to the progression of GBM. Therefore, studies into the regulatory mechanisms of cancer cell growth in GBM are required to identify potential therapeutic targets and improve treatment for GBM. In the present study, the role of ins...

Authors: Zhang X, Chen L Abstract Renal cell carcinoma (RCC) and chronic kidney disease (CKD) are associated with hypoxia, but the effects of hypoxia on the process of angiogenesis in the two diseases are dramatically different. Some of matrix metalloproteinases (MMPs), such as MMP2 and MMP9, may have a role because they represent the most prominent family of proteinases associated with angiogenesis. In the present study, the differential response of human renal cell cancer cells (786-0), human renal tubular epithelial cells (HK-2) and human microvascular endothelial cells (HMEC-1) to hypoxia with regards to the ex...

Authors: Lee SY, Lim S, Cho DH Abstract A 16-year-old female with Ewing sarcoma, a very rare disease with poor prognosis in women, was admitted to the hospital with abdominal pain. Diagnostic laparotomy revealed the Ewing sarcoma originating from the extramural uterus. Histological examination yielded positive test results for CD99, vimentin, S-100, eosin 5-maleimide and periodic acid-Shiff. EWS-FLI1 type 1 translocation was confirmed. Fibroblast growth factor receptor (FGFR) 4 (c.1162G> A) and HRas proto-oncogene (HRAS; c.182A> G) mutations were also detected. At eight months following complete remission, pe...

Authors: Mathur P, Jha S, Ramteke S, Jain NK Abstract Silver nanoparticles are particles in the size ranging between 1 and 100 nm. The two major methods used for synthesis of silver nanoparticle are the physical and chemical methods with the disadvantage that they are expensive and can also have toxicity. Biological method is being used as an expedient alternative, as this approach is environment-friendly and less toxic and it includes plant extracts, microorganism, fungi, etc. The major applications of silver nanoparticles in the medical field include diagnostic applications and therapeutic applications, ap...

Conclusion: To address the many challenges posed by EDCs, we argue that Africans should take the lead in prioritization and evaluation of environmental hazards, including EDCs. We recommend the institution of education and training programs for chemical users, adoption of the precautionary principle, establishment of biomonitoring programs, and funding of community-based epidemiology and wildlife research programs led and funded by African institutes and private companies. https://doi.org/10.1289/EHP1774 Received: 16 February 2017 Revised: 22 May 2017 Accepted: 24 May 2017 Published: 22 August 2017 Address correspond...

Endometriosis currently affects ~5.5 million reproductive-aged women in the U.S. with symptoms such as painful periods (dysmenorrhea), chronic pelvic pain, pain with intercourse (dyspareunia), and infertility. It is defined as the presence of endometrial tissue outside the uterine cavity and is found predominately attached to sites within the peritoneal cavity. Diagnosis for endometriosis is solely made through surgery as no consistent biomarkers for disease diagnosis exist. There is no cure for endometriosis and treatments only target symptoms and not the underlying mechanism(s) of disease. The nature of individual predis...

Mozambique doesn't have any living rhinos left, but the country is still a hub for the illicit, and highly lucrative, trade in endangered animal parts. In an increasingly common show of force against poachers, wildlife officials destroyed more than 425 pounds of rhino horn and two tons of elephant ivory on Monday. The cache was seized in Maputo, Mozambique's capital, earlier this year in what The Guardian calls the biggest haul of rhino horn ever. The goods represent more than 200 animals that were killed for their horns and tusks, according to Agence France-Presse. Based on conservative estimates, the total value of th...
