Diclofenac (DCF) is a non-steroidal analgesic and antiphlogistic. Due to its tremendous use, DCF can be found in the environment, especially in sewage, but also surface waters, ground and drinking water. Previous studies indicated that DCF can modulate the reproductive physiology of fish by altering the expression of important key enzymes of the hypothalamus-pituitary-gonad-axis (HPG-axis) and might act as an estrogenic endocrine disrupting chemical (EDC). Other studies, however, demonstrated that DCF does not exhibit any estrogenicity...

BACKGROUND: The associations between dysglycemia and mortality in septic patients with and without diabetes are yet to be confirmed. Our aim was to analyze the association of diabetes and sepsis mortality, and to examine how dysglycemia (hyperglycemia, hypoglycemia and glucose variability) affects in-hospital mortality of patients with suspected sepsis in emergency department (ED) and intensive care units. METHODS: Clinically suspected septic patients admitted to ED were included, and stratified into subgroups according to in-hospital mortality and the presence of diabetes...

Fluoroquinolones (FQs) are a frequently prescribed class of antibacterial agents. FQs are widely used but may carry serious side effects particularly pronounced in older adults, and the Food and Drug Administration recently suggested FQs should not be routinely used in certain conditions if alternative options are available. Research has demonstrated that the risk of tendinitis and tendon rupture associated with FQs is one of the highest in older adults who are concurrently treated with steroids. Health care providers and pharmacists involved in the treatment of older adults should be aware of this potential drug interaction, which may lead to serious side effects and safety concerns...

After administration of steroids to animals the steroids are partially metabolised in the liver and kidney to phase 2 metabolites, i.e., glucuronic acid or sulphate conjugates. During analysis these conjugated metabolites are normally deconjugated enzymatically with aryl sulphatase and glucuronidase resulting in free steroids in the extract. It is well known that some sulphates are not deconjugated using aryl sulphatase; instead, for example, solvolysis can be used for deconjugation of these aliphatic sulphates...

Inhaled oligonucleotide is an emerging therapeutic modality for various common respiratory diseases, including obstructive airway diseases like asthma and chronic obstructive pulmonary disease (COPD) and restrictive airway diseases like idiopathic pulmonary fibrosis (IPF). The advantage of direct accessibility for oligonucleotide molecules to the lung target sites, bypassing systemic administration, makes this therapeutic approach promising with minimized potential systemic side effects. Asthma, COPD, and IPF are common chronic respiratory diseases, characterized by persistent airway inflammation and dysregulated tissue repair and remodeling, although each individual disease has its unique etiology...

Sulfur mustard (SM) is a strong blistering, highly reactive, lipophilic chemical war agent that causes injury in different organs including the skin, eyes and respiratory tract. The Eyes are especially susceptible to the consequences of SM poisoning because of the aqueous and mucosal nature of conjunctiva and cornea. DNA alkylation and depletion of glutathione, are the most important mechanisms of SM action in the eye injuries. Acute clinical symptoms are including decrease in visual acuity, dryness, photophobia, blepharospasm, conjunctivitis and complaints of foreign body sensation and soreness that gradually progress to severe ocular pain...

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely detected pharmaceuticals in surface water worldwide. The NSAID diclofenac is used to treat many types of pain and inflammation. Diclofenac's potential to cause adverse effects in exposed wildlife is a growing concern. To evaluate the effects of waterborne diclofenac on the immune response in Rhamdia quelen (South American Catfish), fish were exposed to three concentrations of diclofenac (0.2, 2.0, and 20.0 µg/L) for 14 days. Some of the exposed fish were also given an intraperitoneal injection on day 14 of 1 mg/kg of carrageenan to evaluate cell migration to the peritoneum...

Patients presenting with bone marrow fibrosis not accompanied by well-established autoimmune diseases, such as systemic lupus erythematosus, or malignant diseases, are considered to have primary autoimmune myelofibrosis (AIMF). Primary AIMF has been reported to follow a benign course and responds well to treatment with immunosuppressive agents. Immune thrombocytopenia (ITP) is also an autoimmune disorder characterized by antiplatelet-antibody-mediated thrombocytopenia in the absence of other causes of thrombocytopenia...

Stanozolol is a synthetic heterocyclic steroid with anabolic and androgenic properties, which has been abused by several high-profile professional athletes. Stanozolol is also used in veterinary medicine to increase appetite, cause weight gain and treat certain types of anemia. The detection of stanozolol metabolites in human urine for doping control purposes depends on the analytical method applied. The most commonly applied methods in the World Anti-Doping Agency (WADA)-accredited doping control laboratories are gas chromatography/high-resolution mass spectrometry (GC/HRMS) or gas chromatography-mass spectrometry (GC/MS/MS)...

The death of larval salivary gland cells during metamorphosis in Drosophila melanogaster has been a key system for studying steroid controlled programmed cell death. This death is induced by a pulse of the steroid hormone ecdysone that takes place at the end of the prepupal period. For many years, it has been thought that the ecdysone direct response gene Eip93F (E93) plays a critical role in initiating salivary gland cell death. This conclusion was based largely on the finding that the three "type" alleles of E93 cause a near-complete block in salivary gland cell death...

Progesterone Receptor Membrane Component 1 (PGRMC1) is located in many different subcellular locations with many different attested and probably location-specific functions. PGRMC1 was recently identified in the mitochondrial outer membrane where it interacts with ferrochelatase, the last enzyme in the heme synthetic pathway. It has been proposed that PGRMC1 may act as a chaperone to shuttle newly synthesized heme from the mitochondrion to cytochrome P450 (cyP450) enzymes. Here we consider potential roles that PGRMC1 may play in transferring heme, and other small hydrophobic ligands such as cholesterol and steroids, between the hydrophobic compartment of the membrane lipid bilayer interior to aqueous proteins, and perhaps to the membranes of other organelles...

Gonadal steroids and their metabolites have been shown to be important modulators of emotional behavior. Allopregnanolone (ALLO), for example, is a metabolite of progesterone that has been linked to anxiety-related disorders such as posttraumatic stress disorder. In rodents, it has been shown to reduce anxiety in a number of behavioral paradigms including Pavlovian fear conditioning. We have recently found that expression of conditioned contextual (but not auditory) freezing in rats can be suppressed by infusion of ALLO into the bed nucleus of the stria terminalis (BNST)...

BACKGROUND: Postmenopausal obesity is associated with increased circulating levels of androgens and estrogens and elevated breast cancer risk. Crown-like structures (CLS; microscopic foci of dying adipocytes surrounded by macrophages) are proposed to represent sites of increased aromatization of androgens to estrogens. Accordingly, we examined relationships between CLS and sex-steroid hormones in breast adipose tissue and serum from postmenopausal breast cancer patients. METHODS: Formalin-fixed paraffin embedded benign breast tissues collected for research from postmenopausal women (n = 83) diagnosed with invasive breast cancer in the Polish Breast Cancer Study (PBCS) were evaluated...
