Novel and alternative options are being adopted to combat the initiation and progression of human cancers. One of the approaches is the use of molecules isolated from traditional medicinal herbs, edible dietary plants and seeds that play a pivotal role in the prevention/treatment of cancer, either alone or in combination with existing chemotherapeutic agents. Compounds that modulate these oncogenic processes are potential candidates for cancer therapy and may eventually make it to clinical applications. Diosgenin is a naturally occurring steroidal sapogenin and is one of the major bioactive compounds found in dietary fenugreek ( Trigonella foenum-graecum ) seeds...

Steroid hormones (SHs) are continuously released into the aquatic environment through various pathways after being excreted by humans and animals, interfere with the normal function of the endocrine system and may affect the physiology and reproduction of exposed aquatic life. To conduct a nationwide investigation of the occurrence and biological effects of SHs in surface river/steam water in China, we quantitated 27 selected SHs in 217 surface water samples by solid-phase extraction (SPE) tandem LC-MS/MS and used a recombinant yeast estrogen assay to screen extracts of the water samples for estrogenic activities...

Chronic lymphocytic leukemia (CLL) is not considered a hormone-regulated cancer although sex is a recognized risk factor with men more frequently diagnosed and developing progressive disease. We hypothesized that variable hormonal exposure may have a sexually dimorphic influence on treatment-free survival (TFS). In 156 CLL cases, we quantitatively profiled 29 circulating steroids (progesterone, adrenal precursors, androgens, estrogens, and catechol estrogens) as well as luteinizing hormone (LH) and follicle-stimulating hormone...

Environmental gestagens are an emerging class of contaminants that have been recently measured in surface water and can interfere with reproduction in aquatic vertebrates. Gestagens include endogenous progestogens, such as progesterone (P4), which bind P4-receptors and have critically important roles in vertebrate physiology and reproduction. Gestagens also include synthetic progestins, which are components of human and veterinary drugs, such as melengestrol acetate (MGA). Endogenous progestogens are essential in the regulation of reproduction in mammalian species, but the role of P4 in amphibian larval development remains unclear...

REVIEW
T C Guillette, Thomas W Jackson, Scott M Belcher
The physiological actions of estrogens are primarily mediated by the nuclear hormone receptors estrogen receptor alpha (ERα) and beta (ERβ). Activities of these nuclear steroid hormone receptors in etiology and progression of many hormone-responsive cancers are well-established, yet the specific role of each receptor, and their various expressed isoforms, in estrogen-responsive cancers remains unclear. Recent advances in nuclear receptor profiling, characterization of expressed splice variants, and the availability of new experimental cancer models, has extended the understanding of the complex interplay between the differentially expressed nuclear estrogen receptors...

Waldenström's macroglobulinemia (WM) is a B-cell lymphoproliferative disease with serum IgM monoclonal component and bone marrow infiltration by lymphoplasmacytic lymphoma. Traditional therapy was based on that regimens used for closely related entities, such as chronic lymphocytic leukemia or multiple myeloma. This resulted in a lack of drugs specifically approved for WM, until the discovery of the BTK inhibitors. Areas covered. Two main therapeutic attitudes are possible: 1) conventional therapies based on combinations with alkylating agents or proteasome inhibitors with steroids and anti-CD20 monoclonal antibodies, or; 2) new approaches with BTK inhibitors, usually alone...

The complex nature of marine biodiversity is partially responsible for the lack of studies in Indian ascidian species, which often target a small number of novel biomolecules. We performed untargeted metabolomics using gas chromatography-mass spectrometry (GC-MS) in two invasive ascidian species to investigate the inter-specific chemical diversity of Phallusia nigra and P. arabica in search of drug-like properties and metabolic pathways. The chemical profiling of individual ascidian species was obtained using GC-MS, and the metabolites were determined by searching in NIST library and literature data...

Hindbrain-derived stimuli restrain the gonadotropin-releasing hormone (GnRH)-pituitary luteinizing hormone (LH) reproductive neuroendocrine axis during energy insufficiency. Interruption of food intake, planned or unplanned, is emblematic of modern life. This study investigated the premise that the hindbrain energy sensor adenosine 5'-monophosphate-activated protein kinase (AMPK) inhibits reproductive neuroendocrine function in short-term, e.g. 18 hr food-deprived (FD) estradiol (E)-implanted ovariectomized female rats...

BACKGROUND: Enteric-coated mycophenolate sodium (EC-MPS) is frequently used in renal transplantation. The pharmacokinetic profile of mycophenolic acid (MPA) shows a broad range of time-to-maximum-concentration (Tmax) that limits the use of a single MPA concentration to calculate the area under the time-concentration curve (AUC). For both research and clinical MPA monitoring, measuring a complete AUC is troublesome to the center and patients. METHODS: We obtained 171 complete MPA-AUC12h (0, 20,40,60,90,120, 180, 240, 360, 480, 600, 720 min) from 59 adult (54±16 years) patients (29 male, 43 whites) who have been receiving stable doses of Tacrolimus/EC-MPS and steroids...

The urinary 'steroid profile' in doping control analysis is a powerful tool aiming to detect intra-individual deviations related to the abuse of endogenous steroids. Factors altering the 'steroid profile' include among others the excessive fluid intake leading to low endogenous steroids concentrations compared to an individual`s normal values. Cases report the use of hyperhydration by athletes as a masking method during anti-doping urine sample collection. Seven healthy physically active non-smoking Caucasian males were examined for a 72-h period using water and a commercial sports drink as hyperhydration agents (20 mL/kg body weight)...

Hypereosinophilic syndromes (HES) are a heterogeneous group of disorders characterized by peripheral eosinophilia and eosinophil-related end organ damage. Whereas most patients respond to glucocorticoid (GC) therapy, high doses are often necessary and side effects are common. Dexpramipexole (KNS 760704), an orally bioavailable synthetic amino-benzothiazole, showed an excellent safety profile and was coincidentally noted to significantly decrease absolute eosinophil counts (AEC) in a phase 3 trial for amyotrophic lateral sclerosis...

The aim of this research was the identification of novel pharmacogenomic biomarkers for better understanding the complex gene regulation mechanisms underpinning glucocorticoid (GC) action in paediatric inflammatory bowel disease (IBD). This goal was achieved by evaluating high-throughput microRNA (miRNA) profiles during GC treatment, integrated with the assessment of expression changes in GC receptor (GR) heterocomplex genes. Furthermore, we tested the hypothesis that differentially expressed miRNAs could be directly regulated by GCs through investigating the presence of GC responsive elements (GREs) in their gene promoters...

Hydralazine is a direct-acting vasodilator, which has been used in treatment for hypertension (HTN) since the 1950s. While it is well known to cause drug-induced lupus (DIL), recent reports are indicating the emergence of the drug-induced anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (DIV). Herein, we describe two patients (aged 57 and 87 years) who presented with severe acute kidney injury (AKI), proteinuria, and hematuria. Both were receiving hydralazine for the treatment of hypertension...

The higher incidence of arterial and venous events is well established in patients with rheumatoid arthritis (RA). Our aim here was to investigate whether there is a prothrombotic state in RA patients by using rotational thromboelastometry (ROTEM) method and to demonstrate whether the disease variables play a role in this process. A total of 85 patients who met the 2010 RA classification criteria were consecutively included in the study. The patients with RA who have been using antiaggregant, anticoagulant, or nonsteroidal anti-inflammatory drugs (NSAIDs) and had a history of arterial or venous thromboembolism were excluded from the study...
