Vedat Eljezi, Claire Biboulet, Henri Boby, Pierre Schoeffler, Bruno Pereira, Christian Duale
BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) can reduce postoperative pain, in both static (i.e., at rest) and dynamic contexts (e.g., during coughing or mobilization), and reduced doses could improve their efficacy/tolerance balance. OBJECTIVES: To test this hypothesis of efficacy after open heart surgery, in which NSAIDs are poorly used, particularly for safety concerns. STUDY DESIGN: Randomized, double-blind trial. SETTING: Single-center, French university hospital...

A novel targeting drug delivery system for cancer therapy based on H(+)-triggered bubble-generating nanosystems (BGNSs) was engineered. First, hollow mesoporous silica nanoparticles (HMSNs) were used to load doxorubicin (DOX). Then, the obtained drug-loaded HMSNs were treated with NaHCO3 to prepare the BGNSs. The BGNSs were coated with polydopamine (pDA), and finally, folic acids (FA) were anchored on the nanosystems to obtain the desired nanoscale drug delivery system (BGNSs@pDA-FA). BGNSs@pDA-FA was effectively internalized by cancer cells through folate receptor-mediated endocytosis and generated CO2 bubbles under the acidic environment of the lysosomes, thus enhancing lysosomal membrane permeability (LMP) to release caspase-3 into the cytoplasm, resulting in cancer cell death via an apoptosis-like pathway...

REVIEW
Mohammad Izzat Abdul Rahim, Rhys Huw Thomas
Adherence to medication regimens is a crucial factor in seizure-freedom and well-being for people with epilepsy. In contrast, taking medication inconsistently increases the risk of not only seizures and their adverse effects, but drug side-effects and unnecessary modifications to treatment plans. Epilepsy is prevalent across all age groups and we have been slow to utilise both the technologies and psychologies derived from computer gaming. Gaming has broken through to the mainstream and is no longer the preserve of younger males, mirroring the adoption of smart-phones...

Siyu Xu, Naomichi Yamamoto
Ribavirin is an antiviral drug that is used to treat a wide range of human viral infections. However, the side effects are reported, and the mechanisms on eukaryotic cells are still largely unknown. Here we report our observation of accumulation followed by reduction of small nuclear (sn)RNAs and small nucleolar (sno)RNAs in Saccharomyces cerevisiae exposed to ribavirin. The three strains reported to contain dsRNA virus-like particle(s) were exposed to 100 μM of ribavirin, and snRNAs and snoRNAs from a total of 31 snR genes were differentially detected between the samples exposed to ribavirin and the respective negative controls by mRNA-Seq...

The aim of this European Heart Rhythm Association (EHRA) survey was to evaluate clinical practice regarding cardio-oncologic patients, with special focus on patients with cardiac implantable electronic devices (CIEDs) planned for anticancer radiotherapy (RT), among members of the EHRA electrophysiology research network. Of the 36 responding centres, 89% managed patients who were diagnosed or treated oncologically, and this diagnosis affected 1-5% of cardiovascular patients in majority of centres (57%). The main side effects of anticancer therapy in patients treated by cardiologists were thromboembolic complications and left ventricular dysfunction (both reported as 'frequent' by 43% of the centres)...

One of the side-effects of ketamine abuse is genito-urinary damage. This report describes a case of a former ketamine user who presented with urinary symptoms associated with ketamine years after stopping consumption. This was a 26-year-old male with a history of ketamine abuse. He started treatment for alcohol dependence at age 19. He smoked marijuana daily and denied any other drug use. During the follow-up, urinary symptoms were evidenced (dysuria, frequency, urgency, incontinence, nocturia, hematuria, and suprapubic pain)...

INTRODUCTION: Wound care dressings have evolved over time, from bandaging to the development of occlusive dressings to negative pressure wound therapy. A novel therapeutic delivery system dressing has been cleared by the United States Food and Drug Administration. This semi occlusive wound dressing has been developed to provide local, continuous delivery of aqueous topical agents, such as therapeutics (anesthetics, antiseptics, antibiotics, steroids, topical beta-blockers, immune modulatory agents, growth factors, and fibrinolytic agents, among others), at a rate of about ¾ mL per day, thus maintaining a hydrated environment and providing topical treatment...

Consistent disparities in influenza (flu) vaccine uptake among African Americans, coupled with a disproportionate burden of chronic diseases, places too many African Americans at high risk for complications, hospitalizations and premature mortality. This disparity is the result of individual attitudes and beliefs, social norms, and health care practices. Recent research identifies critical factors affecting vaccine uptake among African American adults including perceived risk of vaccine side effects, social norms that do not support for vaccination, and lower knowledge of the flu and the vaccine...

We use molecular dynamics simulations to study the exfoliation of graphene and fluorographene in molecular and ionic liquids, by performing computer experiments in which one layer of the 2D nanomaterial is peeled from a stack, in vacuum and in the presence of solvent. The liquid media and the nanomaterials are represented by fully flexible, atomistic force fields. From these simulations we calculate the potential of mean force, or reversible work, required to exfoliate the materials. Calculations in water and organic liquids showed that small amides (NMP, DMF) are among the best solvents for exfoliation, in agreement with the experiment...

Various types of piperidinium ionic liquids (ILs) equipped with an oxygen atom-containing alkyl side chain on the positively charged nitrogen atom were systematically synthesized and their physical properties investigated. The thermal stability, viscosity, electrochemical window, and ion conductivity were influenced significantly by changing the position of the oxygen atom in the alkyl chain. Although the lowest viscosity was recorded for 1-((2-methoxyethoxy)methyl)-1-methylpiperidin-1-ium bis(trifluoromethylsulfonyl)amide ([PP1MEM][Tf2N]), 1-methyl-1-(2-propoxyethyl)piperidin-1-ium bis(trifluoromethylsulfonyl)amide ([PP1PE][Tf2N]) can be recommended as the best IL as an electrolyte due to its low viscosity and high thermal and electrochemical stability among the seven ILs tested...

One of the main appeals of using gold nanoparticles (GNPs) as radiosensitizers is that their surface coatings can be altered to manipulate their pharmacokinetic properties. However, Monte Carlo studies of GNP dosimetry tend to neglect these coatings, potentially changing the dosimetric results. This study quantifies the dosimetric effects of including a polyethylene glycol (PEG) surface coating on GNPs over both nanoscopic and microscopic ranges. Two dosimetric scales were explored using PENELOPE Monte Carlo simulations...

BACKGROUND AND OBJECTIVE: Increasing evidence has demonstrated that dietary products and their active components are independently or jointly responsible for the apparent reduction of the cardiovascular diseases (CVDs) risk. DISCUSSION: Nowadays, there is a growing attention in the use of nutraceuticals as a new approach for the prevention and management of many diseases, as well as for controlling rising of chronic illnesses with minimal side effects. Food-derived peptides, as well as peptide-rich protein hydrolysates, represent new and valuable tools for the prevention of metabolic and cardiovascular diseases, acting as modulators of oxidative stress, inflammation, and overactivity of the renin-angiotensin system (RAS)...

The main tackle of cancer treatment is multidrug resistance during chemotherapy. Cancer cell can evade cell death during every round of orthodox chemotherapy drugs, consequently being resistance after several rounds of standard drug treatment. One of the regimens to address this multidrug resistance problem is by drug combination. However, synthetic drugs always have problems of strong side effects and toxicity. Natural compounds deriving from traditional Chinese medicine are known to have low toxicity and genuine promising effects in reversing multidrug resistance, either induced by orthodox chemotherapeutic or targeted therapy drugs...

Pharmacotranscriptomics aims to reach more accurate drug dosing based on interindividual transcriptome variations. Here, we provide an overview of RNA biomarkers that could predict the response to glucocorticoids (GCs), considered the standard for treatment of inflammatory bowel diseases (IBD), both in adult and pediatric patients. Although new biological agents are very effective in the IBD treatment, GCs are still widely used for induction of remission in IBD patients with moderate to severe disease. It is important to identify patients that are poor responders to GCs therapy, because suboptimal response is frequent and associated with various side effects...

Phototherapies including photothermal therapy (PTT) and photodynamic therapy (PDT) have emerged as one of the avant-garde strategies for cancer treatment. Photoacoustic (PA) imaging is a new hybrid imaging modality that shows great promise for real-time in vivo monitoring of biological processes with deep tissue penetration and high spatial resolution. To enhance therapeutic efficiency and reduce side effects, it is necessary to explore the combination of cancer therapy and diagnosis. Nanotheranostics composed of PTT/PDT and PA imaging are emerging to provide unprecedented advantages in accelerating cancer theranostics...

Two female breast cancer patients developed epiphora after administration of Cyclophosphamide and/or anthracyclines based 2-day chemotherapy regimen. The ophthalmologist was consulted and no apparent cause was found. Both patients was managed by ciprofloxacin eye drops. Chemotherapy-induced ocular complications are not uncommon, but under-reported. Although epiphora is a mild reaction if severe can interfere with daily activities. Patients receiving anticancer drugs should have a thorough ocular evaluation, in order to prevent, early diagnose and efficiently treat established ocular complications of the chemotherapy treatment...

BACKGROUND: Notable progress has been made in chemo- and immunotherapy of B-cell lymphomas, but less in the treatment of T-cell lymphomas. OBJECTIVE: Histone deacetylases inhibitors are a potentially useful therapeutic mean, as an epigenetic dysregulation is present in lymphomas, and especially in T-cell types. We aimed to study the progress made in this area. METHOD: A minireview was achieved using the articles published in PubMed in the last two years and the new patents made in this field...

Traumatic brain injury (TBI) is one of the leading causes of death and disability in the population worldwide, with a broad spectrum of symptoms and disabilities. Posttraumatic hyperexcitability is one of the most common neurological disorders that affect people after a head injury. A reliable animal model of posttraumatic hyperexcitability induced by TBI which allows one to test effective treatment strategies is yet to be developed. To address these issues, in the present study, we tested human embryonic stem cell-derived neural stem cell (NSC) transplantation in an animal model of posttraumatic hyperexcitability in which the brain injury was produced in one hemisphere of immunodeficient athymic nude rats by controlled cortical impact, and spontaneous seizures were produced by repeated electrical stimulation (kindling) in the contralateral hemisphere...
