Proteasome inhibitors have been frequently used in treating hematologic and solid tumors. They are administered individually or in combination with other regimens, to prevent severe side effects and resistance development. Since they have been shown to be efficient and are pharmaceutically available, we tested the first FDA-approved proteasome inhibitor bortezomib alone and in combination with another proteasome inhibitor, salinosporamid A, in pheochromocytoma cells. Pheochromocytomas/paragangliomas (PHEOs/PGLs) are neuroendocrine tumors for which no definite cure is yet available...

A new molecular biology based taxonomy has been proposed for pheochromocytoma and paraganglioma (PPGL). Data from the Cancer Genome Atlas revealed clinically relevant prognostic and predictive biomarkers and stratified PPGLs into three main clusters. Each subgroup has a distinct molecular-biochemical-imaging signature. Concurrently, new methods for biochemical analysis, functional imaging, and medical therapies have also become available. The research community now strives to match the cluster biomarkers with the most superior intervention...

To date, existing tissue adhesives have various weak points in gluing kinetics and stability - particularly, in biocompatibility, which make most of them remain suboptimal for internal conditions. Herein, a novel mussel-inspired "BCD" tissue glue made of bovine serum albumin (BSA), citrate acid (CA) and dopamine was developed aiming at internal medical applications. BSA was employed as a natural and biocompatible macromolecular backbone; CA was introduced as a dual-functional intermediate to increase reactive carboxyl sites for engraftment of dopamine onto BSA backbone and also block the competing reactive amines from the proteinic backbone...

Cerebral palsy is the most common cause of physical disability in children, and there is no cure. Umbilical cord blood (UCB) cell therapy for the treatment of children with cerebral palsy is currently being assessed in clinical trials. While there is much interest in the use of UCB stem cells for neuroprotection and neuroregeneration, the mechanisms of action are not fully understood. Further, UCB contains many stem and progenitor cells of interest, and we will point out that individual cell types within UCB may elicit specific effects...

OBJECTIVE: A watch and wait policy for patients with a complete clinical response (cCR) after external beam chemoradiotherapy (EBCRT) for rectal cancer is an attractive option. However, approximately a third of tumours will regrow, which requires surgical salvage for cure. We assessed whether contact x-ray brachytherapy (CXB) can improve organ preservation by avoiding surgery for local regrowth. METHODS: From our institutional database, we identified 200 of 573 patients treated by CXB from 2003 to 2012...

In case of severe illnesses such as dementia it is important to keep inquiring how the person concerned and his or her social network view and experience the illness. For conditions that cannot be cured, family and social ties have proven to be the most important factors in experiencing quality of life. In case of dementia, people can be distressed when they feel excluded from such conversations. Family members are often only approached in their roles as informal caregivers or representatives. However, by also discussing other roles in relationships, families and friendships and by alternating in these conversations between the positions of so-called expert and advisor, doctors can contribute to preventing connections from breaking off prematurely...

Dementia is tough for the person who is suffering from it, but also stressful for the entourage. The decrease of contact and recognition is difficult for these 'shadow victims of the disorder'. Looking at dementia as mere 'memory loss' may cause feelings of powerlessness, since there is currently no medication that can prevent or cure this deterioration process. Shifting the emphasis to 'loss of communication' makes the problem somewhat easier to deal with. What if advertising techniques could boost the challenging dialogue with people suffering from dementia?...

As a multi-factorial degenerative disease, Parkinson's disease (PD) leads to tremor, gait rigidity, and hypokinesia, thus hampering normal living. As this disease is usually detected in the later stages when neurons have degenerated completely, cure is on hold, ultimately leading to death due to the lack of early diagnostic techniques. Thus, biomarkers are required to detect the disease in the early stages when prevention is possible. Various biomarkers providing early diagnosis of the disease include those of imaging, cerebrospinal fluid, oxidative stress, neuroprotection, and inflammation...

Hepatitis B is a significant public health problem in India, yet disease awareness is very low among the general population. The disease is mostly acquired horizontally, but the role of vertical transmission should not be underestimated. In spite of the fact that the majority of cases are e negative disease, most patients present in the advanced stage and even with hepatocellular carcinoma, the leading cause of which is hepatitis B. High-risk groups (especially tribals) also harbour significant disease burden and have a high prevalence of occult infection, supporting the potential of unknowingly spreading the disease...

BACKGROUND: To facilitate the easier placement of direct resin composite in deeper cavities, bulk fill composites have been introduced. The Mechanical stability of fillings in stress bearing areas restored with bulk-fill resin composites is still open to question, since long term clinical studies are not available so far. Thus, the objective of the study was to evaluate and compare the microtensile bond strength of three bulk-fill restorative composites with a nanohybrid composite. MATERIAL AND METHODS: Class I cavities were prepared on sixty extracted mandibular molars...

N J White, J Watson, E A Ashley
It has been suggested recently, based on pharmacokinetic-pharmacodynamic modelling exercises, that twice daily dosing of artemisinins increases malaria parasite killing and so could "dramatically enhance and restore drug effectiveness" in artemisinin resistant P. falciparum malaria infections. It was recommended that split dosing should be incorporated into all artemisinin combination regimen designs. To explain why parasite clearance rates were not faster with split dose regimens it was concluded that splenic malaria parasite clearance capacity was readily exceeded, resulting in the accumulation of dead parasites in the circulation, that parasite clearance was therefore an unreliable measure of drug efficacy, and instead that human immunity is the primary determinant of clearance rates...

Despite the recent increase in the development of antivirals and antibiotics, antimicrobial resistance and the lack of broad-spectrum virus-targeting drugs are still important issues and additional alternative approaches to treat infectious diseases are urgently needed. Host-directed therapy (HDT) is an emerging approach in the field of anti-infectives. The strategy behind HDT is to interfere with host cell factors that are required by a pathogen for replication or persistence, to enhance protective immune responses against a pathogen, to reduce exacerbated inflammation and to balance immune reactivity at sites of pathology...

BACKGROUND Treatment with DAAs before deceased donor liver transplantation has been shown to be an effective strategy to prevent post-transplant HCV recurrence, with a 95% cure-rate among individuals who achieve undetectable HCV VL for ≥30 days pre- transplant. This strategy has not been evaluated in LDLT. MATERIAL AND METHODS We evaluated outcomes in LDLT recipients treated with DAAs pre-transplant and bridged with 4 weeks of post-transplant SOF. All cases of LDLT at Johns Hopkins (1/1/2014-3/1/15) were retrospectively reviewed...

Biopharmaceuticals are increasingly important for patients and the pharmaceutical industry due to their ability to treat and, in some cases, even cure chronic and potentially life-threatening diseases. Most biopharmaceuticals are administered by injection, but intensive focus on development of systems for oral delivery of biopharmaceuticals may result in new treatment modalities to increase patient compliance and reduce product cost. In the preclinical development phase, use of experimental animal models is essential for evaluation of new formulation designs...
