Background and Aim: Hairy enhancer of split-1 (HES1) is a downstream transcriptional factor of Notch signaling pathway, which was found to be related to chemoresistance. This study was aimed to investigate the role of HES1 in chemoresistance of colorectal cancer (CRC). Methods: Tissue microarray was used to analyze the clinical significance of HES1 in radical resected (R0) stage II/III CRC patients that received adjuvant chemotherapy. 5-fluorouracil (5-Fu) chemoresistance was examined in CRC cell lines (RKO and HCT8, LOVO) with stable over-expression and inhibition of HES1 gene by cytotoxicity test...

OBJECTIVES: The breakthrough advancements in scientific medical research have greatly improved our understanding of the pathogenesis of depression, encouraging drug discoverers to take a shorter path than ever through drug repurposing to generate new antidepressant medications. In addition to reduced noradrenergic and serotonergic neurotransmission in the brain, other coincidence features such as glutamate neurotoxicity, inflammation and/or cerebrovascular insufficiency are implicated in the pathogenesis of major depressive disorder and late-life depression...

BACKGROUND: The clinical relevance of raised levels of circulating cytokines in bipolar disorder is still unclear. Cytokines influence neurotransmitters, neuroplasticity, and white matter integrity. An inconsistent literature suggests that higher cytokine levels could hamper antidepressant response. Total sleep deprivation (TSD) and light therapy (LT) prompt a rapid antidepressant response and can provide a model treatment to study predictors of response. METHODS: We studied at baseline 15 immune-regulating compounds in 37 consecutively admitted inpatients with a major depressive episode in the course of bipolar disorder (DSM-5 criteria) and in 24 controls...

Approximately 30-60% of patients treated with existing antidepressants fail to achieve remission of depressive symptoms leading to Treatment Resistant Depression (TRD). There is an urgent need to develop novel medications, which is highly limited by the non-availability of relevant animal models with good predictive validity. ACTH administration has been shown to result in the resistance to acute and chronic effects of imipramine. However, the pharmacology of the model and the mechanisms contributing to the resistance are not completely understood...

Early trauma and stress exposure during a critical period of life may increase the risk of major depressive disorder (MDD) and post-traumatic stress disorder (PTSD) in adulthood. The first-choice treatment for MDD and PTSD are selective serotonin reuptake inhibitor (SSRI) antidepressants. Unfortunately, half of MDD and PTSD patients show resistance to the therapeutic effects of these drugs and more efficient treatments are essential. Both MDD and PTSD patients present reduced levels of allopregnanolone (Allo), a potent endogenous positive allosteric modulator of GABA action at GABAA receptors which are normalized by SSRIs in treatment responders...

Many epidemiological studies have confirmed the relationship of obesity and psoriasis, and it is believed that obesity is an independent risk factor for its development and is associated with a worse prognosis. Furthermore, the reduction of body weight, using low-calorie diet combined with exercise, reduces the severity of psoriasis.Visceral adipose tissue is the largest endocrine organ, producing proinflammatory cytokines (TNF-α, IL-6, IL-17) and adipokines (adiponectin, omentin, chemerin). They participate in the development of dyslipidemia, insulin resistance, diabetes, and consequently of the cardiovascular diseases...

Electroconvulsive therapy (ECT) is still the most effective strategy to treat severe and drug-resistant depressive disorders. Electroconvulsive seizure (ECS), which induces neuroplastic structural alterations and resilient behavioral changes in experimental animals, is the model of the ECT for human depression. ECT is typically administered three times per week for up to 4 weeks, while ECS treatments are administered daily for 10days. The increased expression of hippocampal brain-derived neurotrophic factor (BDNF) induced by antidepressive ECS treatment in experimental animals has been well documented...

AIM: Metastatic castration resistant prostate cancer (mCRPC) patients are generally older patients with several co-morbidities and are therefore more at risk for complications due to drug-drug interactions(DDIs). We assessed the prevalence of potential DDIs in a cohort of mCRPC patients treated with enzalutamide. METHODS: We conducted a retrospective review of pharmacy records to retrieve individual drug histories of mCRPC patients who started enzalutamide therapy in a tertiary care setting...

Harmaline and harmine occur naturally in plants and are distributed endogenously in human and animal tissues. The two β-carboline alkaloids possess potential for treating Alzheimer's disease, Parkinson's disease, depression and other central nervous system diseases. However, studies have showed that the two compounds have similar structures but with quite different bioavailability. The aim of this study was to elucidate the exposure difference and characterize the in vitro transport, metabolism, and pharmacokinetic properties of harmaline and harmine...

OBJECTIVES: Obstructive sleep apnea (OSA) is a common clinical problem that can have serious health consequences and complicate the course of mental disorders. It is estimated that the prevalence of sleep apnea in patients with bipolar disorder can be 21-47.5%. Some symptoms of OSA are the same as the symptoms of depression: daytime drowsiness, cognitive dysfunction, decreased drive, apathy, depressed mood, anhedonia. METHODS: We present a case of a patient whose depressive symptoms persisted despite repeated changes of pharmacological treatment and were exacerbated by severe sleep disorder...

Pragmatic studies indicate that a substantial number of depressed patients do not remit with current first-line antidepressant treatments and after two failed treatment steps the chance of remission with subsequent therapies is around 15%. This paper focuses on current evidence for pharmacological treatments in resistant depression as well as possible future developments. For patients who have failed to respond to two antidepressant trials, augmentation with atypical antipsychotic drugs, specifically quetiapine and aripiprazole, has the best evidence for efficacy, though older treatments such as lithium and triiodothyronine still have utility...

Depression, anxiety and other affective disorders are globally widespread and severely debilitating human brain diseases. Despite their high prevalence and mental health impact, affective pathogenesis is poorly understood, and often remains recurrent and resistant to treatment. The lack of efficient antidepressants and presently limited conceptual innovation necessitate novel approaches and new drug targets in the field of antidepressant therapy. Areas covered: Herein, the authors discuss the emerging role of neuro-immune interactions in affective pathogenesis, which can become useful targets for CNS drug discovery, including modulating neuroinflammatory pathways to alleviate affective pathogenesis...

Lithium is an established treatment for bipolar disorder and an augmenting agent for treatment-resistant depression. Despite awareness of renal adverse effects, including chronic kidney disease, for the past five decades, there has been a lack of research evidence. This has led to debates around the existence and magnitude of the risk. This article discusses the current evidence base regarding the link between lithium and chronic kidney disease, monitoring of renal functions and its clinical implications.

Sites and mechanisms by which trigeminal nerve stimulation (TNS) exerts beneficial effects on symptoms of drug-resistant epilepsy and depression are still unknown. Effects of short-term TNS on brain regions involved in the physiopathology of these disorders were investigated in this study. Forty male rats were assigned to three groups: TNS (undergoing electrical stimulation of the left infraorbitary nerve via surgically implanted cuff electrodes); Sham (undergoing surgical procedure but without a stimulation); Naïve rats...

BACKGROUND: Nutrition is a prerequisite for health; yet, there is no special nutritional assessment or guidance for drug and alcohol dependent individuals, despite the fact that their food consumption is often very limited, risking malnutrition. Further, the premise is examined that malnutrition may promote drug seeking and impede recovery from substance use disorders (SUD). METHOD: A narrative review addressed the relationship between substance use disorders and nutrition, including evidence for malnutrition, as well as their impact on metabolism and appetite regulation...

OBJECTIVES: Patients with bipolar disorder spend the most time in the depressed phase, and that phase is associated with the most morbidity and mortality. Treatment of bipolar depression lacks a test to determine who will respond to treatment. White matter disruptions have been found in bipolar disorder. Previous reports suggest that white matter disruptions may be associated with resistance to antidepressant medication, but this has never been investigated in a prospective study using a Food and Drug Administration (FDA)-approved medication...
