Testicular germ cell tumors (TGCTs) are the most common cancers of young males. A substantial portion of TGCT patients are refractory to cisplatin. There are no effective therapies for these patients, many of whom die from progressive disease. Embryonal carcinoma (EC) are the stem cells of TGCTs. In prior in vitro studies we found that EC cells were highly sensitive to the DNA methyltransferase inhibitor, 5-aza deoxycytidine (5-aza). Here, as an initial step in bringing demethylation therapy to the clinic for TGCT patients, we evaluated the effects of the clinically optimized, second generation demethylating agent guadecitabine (SGI-110) on EC cells in an animal model of cisplatin refractory testicular cancer...

INTRODUCTION: Immune thrombocytopenic purpura remains common blood disease in Nepal. Azathioprine is an oral immunosupressive medicine which has been used widely in various autoimmune disease and solid organ transplant patients. It is inexpensive, easily available and well tolerated medicine. This study was carried out to evaluate efficacy and safety of azathioprine as a second line medicine for primary ITP patients who were refractory to steroid therapy. METHODS: The observational, pre-post study was conducted at Government of Nepal Civil Service Hospital, Kathmandu from January to October 2014...

Chronic refractory angina is often a disabling condition, predominantly due to severe obstructive coronary artery disease, that is inadequately controlled by optimal medical therapy and not amenable to further percutaneous or surgical revascularization. Mortality rates associated with this condition are relatively low in clinically stable patients. However, it is associated with a high hospitalization rate and a reduction in both exercise capacity and quality of life. Due to the paucity of available treatment options, there is an unmet need for new therapies for these patients and for a reduction in the associated economic healthcare burden...

AIM: There are few reports on the tolerability and efficacy of perampanel, a new antiepileptic drug with a novel mechanism of action, in children and adolescents. We aimed to describe our experience with perampanel add-on and mono-therapy in children with refractory epilepsy. METHOD: Computerized medical records of children treated with perampanel in the paediatric neurology clinic from December 2012 to October 2015 were reviewed. RESULTS: Twenty-four children treated with perampanel (15 females, 9 males) aged 1 year 6 months to 17 years (mean 10y, standard deviation [SD] 4y 5mo) were identified...

BACKGROUND: Extracorporeal Cardiopulmonary Resuscitation (ECPR) has emerged as a feasible rescue therapy for refractory, normothermic out-of-hospital cardiac arrest (OHCA). Reported survival rates vary and comparison between studies is hampered by heterogeneous study populations, differences in bystander intervention and in pre-hospital emergency service organisation. We aimed to describe the first experiences, treatment details, complications and outcome with ECPR for OHCA in a Danish health region...

Peripheral Blood Mononuclear Cells (PBMCs) were collected from a patient with clozapine-resistant (also known as "super-refractory") Schizophrenia. iPSCs were established with a non-integrating Sendai virus-based reprogramming system. A footprint-free hiPSC line was characterized to express the main endogenous pluripotency markers and to retain a normal karyotype. Cells showed pluripotency competency by giving rise to progeny of differentiated cells belonging to the three germ layers. This hiPSC line represents a valuable tool to obtain mature, pathology-relevant neuronal populations in vitro that are suitable to investigate the molecular background of the schizophrenic disorder and the resultant patients' response to treatments...

Peripheral blood mononuclear cells (PBMCs) were collected from a patient with treatment-refractory Schizophrenia who presented an exceptional clinical response to Clozapine. iPSC lines were established with a non-integrating reprogramming system based on Sendai virus. A footprint-free hiPSC line was characterized to confirm the expression of the main endogenous pluripotency markers and have a regular karyotype. Pluripotency was confirmed by differentiation into cells belonging to the three germ layers. This hiPSC line represents a valuable tool to study the molecular, biochemical and electrophysiological properties of mature neuronal populations belonging to Clozapine responder patients with a severe form of Schizophrenia...

Recently, visible-light-driven photocatalysis is of great interest in the environmental pollutant remediation. In the present study, a novel heterostructured photocatalyst AgI/BiVO4 was synthesized by an in situ precipitation procedure. The AgI/BiVO4 heterojunctions exhibited excellent photoactivity for the refractory pollutant (tetracycline (TC), a typical antibiotic) decomposition under visible light illumination. The synthetic sample with 1:4 mass ratio of AgI:BiVO4 possessed the highest photocatalytic performance in all of the as-prepared catalysts...

BACKGROUND: Pruritus is a distressing symptom in a considerable proportion of cholestatic patients and a few of them do not respond to conventional treatment. Charcoal hemoperfusion (CH) is an extracorporeal technique that is effective in eliminating protein-bound substances which may have accumulated during cholestasis. Several case reports have shown significant reduction of bilirubin in mechanical jaundice and neonatal hemolytic jaundice. However, the published data of CH for the treatment of refractory pruritus in cholestatic patients are scarce...

New classes of drugs including the proteasome inhibitors (PI) bortezomib and, more recently, carfilzomib and the immunomodulatory agent lenalidomide have shown improved outcomes for multiple myeloma (MM) patients during the past decade. However, most of the studies reporting outcomes for patients receiving these drugs have relied on older data sets derived from large institutions that included patients not receiving their treatment at those facilities and represented only those eligible for clinical trials or were from sites where treatment options were limited...

Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. Many patients with mild reflux symptoms are treated adequately with lifestyle modifications, dietary changes, and low-dose proton pump inhibitors (PPIs). For those with refractory GERD poorly controlled with daily PPIs, numerous treatment options exist. Fundoplication is currently the most commonly performed antireflux operation for management of GERD...

Autoimmune regulator (Aire) is a transcriptional regulator of peripheral tissue antigens (PTAs) and microRNAs (miRNAs) in medullary thymic epithelial cells (mTECs). In this study, we tested the hypothesis that Aire also played a role as an upstream posttranscriptional controller in these cells and that variation in its expression might be associated with changes in the interactions between miRNAs and the mRNAs encoding PTAs. We demonstrated that downregulation of Aire in vivo in the thymuses of BALB/c mice imbalanced the large-scale expression of these two RNA species and consequently their interactions...

REVIEW
Ilse S Pienaar, Anthony Vernon, Philip Winn
The pedunculopontine nucleus (PPN) is a rostral brainstem structure that has extensive connections with basal ganglia nuclei and the thalamus. Through these the PPN contributes to neural circuits that effect cortical and hippocampal activity. The PPN also has descending connections to nuclei of the pontine and medullary reticular formations, deep cerebellar nuclei, and the spinal cord. Interest in the PPN has increased dramatically since it was first suggested to be a novel target for treating patients with Parkinson's disease who are refractory to medication...

Small cell lung cancer (SCLC) is a devastating disease due to its propensity for early invasion and refractory relapse after initial treatment response. Although these aggressive traits have been associated with phenotypic heterogeneity, our understanding of this association remains incomplete. To fill this knowledge gap, we inferred a set of 33 transcription factors (TF) associated with gene signatures of the known neuroendocrine/epithelial (NE) and non-neuroendocrine/mesenchymal-like (ML) SCLC phenotypes...

Extracorporeal membrane oxygenation (ECMO) is a life-support modality used in patients with refractory cardiac and/or respiratory failure. A significant resurgence in the use ECMO has been seen in recent years due to substantial improvements in technology and survival benefit. With expanding ECMO use, a better understanding of how ECMO affects drug pharmacokinetics (PK) is necessary. The vast majority of PK studies in patients receiving ECMO have been conducted within neonatal or pediatric populations or within a controlled environment (e...
