Seasonal variations in the concentrations of eight ultraviolet (UV) filters and 22 illicit drugs including their metabolites in the Korean aquatic environment were investigated. Seawater samples from three beaches, water samples from two rivers, and influents and effluents from three wastewater treatment plants were analyzed. The UV filter concentrations in the seawater, river water, and effluent samples were 39.4-296, 35.4-117, and 6.84-51.1 ng L(-1), respectively. The total UV filter concentrations in the seawater samples were 1...

Patients with metastatic castration-resistant prostate cancer (mCPRC) now have an unprecedented number of approved treatment options, including chemotherapies (docetaxel, cabazitaxel), androgen receptor (AR)-targeted therapies (enzalutamide, abiraterone), a radioisotope (radium-223) and a cancer vaccine (sipuleucel-T). However, the optimal treatment sequencing pathway is unknown, and this problem is exacerbated by the issues of primary and acquired resistance. This review focuses on mechanisms of resistance to AR-targeted therapies and taxane-based chemotherapy...

Mast cells play crucial roles in the initiation of allergic inflammatory responses by releasing various mediators such as histamines, cytokines, and leukotrienes. In addition, signaling cascade pathways, such as the mitogen-activated protein kinase (MAPK) pathway, contribute to the regulation of mast cell degranulation. Accordingly, different research strategies have been pursued to develop anti-inflammatory and anti-allergic drugs by regulating these signaling pathways. The development of new drugs that inhibit mast cell degranulation may help in the treatment of allergies...

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a hypersensitivity reaction associated with a variety of drugs, mainly anticonvulsants, which is characterized by systemic symptoms and erythematous lesions, common to other toxicodermas. It is an uncommon clinical entity that requires a high suspicion by clinical staff given its varied initial presentation, and the fact that symptoms can overlap with those of other adverse cutaneous reactions to drugs. Without early diagnosis and appropriate treatment, mortality increases...

Alzheimer's disease (AD) is a neurodegenerative disorder of the elderly. As the prevalence of AD rises in the 21st century, there is an urgent need for the development of effective pharmacotherapies. Currently, drug treatments target the symptoms of the disease and do not modify or halt the disease progress. Thus, natural compounds have been investigated for their ability to treat AD. This review examines the efficacy of curcumin, a polyphenol derived from turmeric herb, to treat AD. We summarize the in vivo and in vitro research describing the mechanisms of action in which curcumin modifies AD pathology: curcumin inhibits the formation and promotes the disaggregation of amyloid-β plaques, attenuates the hyperphosphorylation of tau and enhances its clearance, binds copper, lowers cholesterol, modifies microglial activity, inhibits acetylcholinesterase, mediates the insulin signaling pathway, and is an antioxidant...

Mucormycosis in humans has been described as early as 1885 in literature. Isolated renal mucormycosis is rare as it has been mainly described in developing countries like India and China. It is rarer still to find this entity in immunocompetent young males without any risk factors. Specific guidelines on the treatment is not yet known but combined surgical and medical therapy is considered the best modality for its management. We describe a young male who presented with bilateral hydroureteronephrosis. He was initially treated as a case renal tuberculosis which is relatively more common in TB endemic country like ours...

Insomnia is highly prevalent and is associated with a range of psychological, psychiatric, and medical conditions. Insomnia affects health by influencing cognitive, emotional and social functioning. Circadian and sleep homeostatic processes play an important role in insomnia development and its maintenance. Several efficacious treatments, both pharmacologic and non-pharmacologic, exist for the management of insomnia. Among non-pharmacologic treatments including stimulus control therapy, sleep restriction, relaxation, sleep hygiene and cognitive therapy have been shown to be efficacious...

HepaRG cells are widely used as an in vitro model to assess drug-induced hepatotoxicity. However, only few studies exist so far regarding their suitability to detect the effects of drugs requiring a preceding activation via the cytochrome P450 (CYP) system. A prototypic substance is the anti-tuberculosis agent INH, which is metabolized into N-acetylhydrazine, which then triggers hepatotoxicity. Therefore, the aim of the present study was to test if this effect can also be detected in HepaRG cells and if it can be counteracted by the known hepatoprotectant silibinin...

Sacubitril/valsartan (LCZ696) is indicated for the treatment of heart failure with reduced ejection fraction. Absorption of sacubitril/valsartan and conversion of sacubitril (prodrug) to sacubitrilat (neprilysin inhibitor) was rapid with maximum plasma concentrations of sacubitril, sacubitrilat, and valsartan (angiotensin receptor blocker) reaching within 0.5, 1.5-2.0, and 2.0-3.0 h, respectively. With a twofold increase in dose, an increase in the area under the plasma concentration-time curve was proportional for sacubitril, ~1...

Since the nineteenth century several clinical features have been observed in common between migraine and epilepsy (such as episodic attacks, triggering factors, presence of aura, frequent familiarity), but only in recent years researchers have really engaged in finding a common pathogenic mechanism. From studies of disease incidence, we understand how either migraine among patients with epilepsy or epilepsy among migraine patients are more frequent than in the general population. This association may result from a direct causality, by the same environmental risk factors and/or by a common genetic susceptibility...

A great deal of studies suggests that cluster headache (CH) patients are usually comorbid to anxiety-mood spectrum disorders and psychopathological symptoms; however, the personality profiles reported in the literature strictly depend on type of assessment used. Psychiatric comorbidities have been extensively studied in migraine and they are recognized to represent a major risk factor associated with poorer outcome, playing a role in the headache chronification process at once as cause and consequence of it...

Emotion and pain are closely intertwined in the brain, as the human experience of pain includes both affective and nociceptive components. Although each of these components relies on a different system in the brain, the two systems converge on the anterior cingulate and insular cortices, which interact with the prefrontal cortex and other frontal structures to influence behavior. Both emotional and physical pain elicit activity in these common areas, and conditions that affect one system (e.g., drugs, neural plasticity) may affect the function of the other-ultimately altering the experience of pain...

Cluster headache is characterized by severe, unilateral headache attacks of orbital, supraorbital or temporal pain lasting 15-180 min accompanied by ipsilateral lacrimation, rhinorrhea and other cranial autonomic manifestations. Cluster headache attacks need fast-acting abortive agents because the pain peaks very quickly; sumatriptan injection is the gold standard acute treatment. First-line preventative drugs include verapamil and carbolithium. Other drugs demonstrated effective in open trials include topiramate, valproic acid, gabapentin and others...

Headache disorders are common worldwide and often disabling. Until recently, treatments were borrowed from other branches of neurology and medicine. Monoclonal antibodies targeting calcitonin gene-related peptide (CGRP) ligand and receptor, small molecule CGRP receptor antagonist gepants, serotonin1F agonists, new devices to deliver currently available drugs, and neuromodulation devices have recently been in the forefront of headache treatments that are rather specific for various headache disorders. These novel therapies are changing the field of headache medicine...
