BACKGROUND AND PURPOSE: It has been suggested that the non-psychoactive phytocannabinoid cannabidiol (CBD) can impact the pharmacological effects of delta-9-tetrahydrocannabinol (THC). We tested the hypothesis that CBD and THC would significantly mitigate mechanical sensitivity in a mouse model of paclitaxel-induced neuropathic pain, and that CBD+THC combinations would produce synergistic effects. We also tested the hypothesis that CBD would attenuate oxaliplatin- and vincristine- induced mechanical sensitivity...

Neglected diseases (NDs) affect large populations and almost whole continents, representing 12% of the global health burden. In contrast, the treatment available today is limited and sometimes ineffective. Under this scenery, the Fragment-Based Drug Discovery (FBDD) emerged as one of the most promising alternatives to the traditional methods of drug development. This method allows achieving new lead compounds with smaller size of fragment libraries. Even with the wide Fragment-Based Drug Discovery success resulting in new effective therapeutic agents against different diseases, until this moment few studies have been applied this approach for NDs area...

Despite improvements in treatment of different types of leukemia, not all patients respond optimally for a particular treatment. Some treatments will work better for some, while being harmful or ineffective for others. This is due to genetic variation in the form of single-nucleotide polymorphisms (SNPs) that affect gene expression or function and cause inherited interindividual differences in the metabolism and disposition of drugs. Drug transporters are one of the determinants governing the pharmacokinetic profile of chemotherapeutic drugs...

INTRODUCTION: blood saving strategy during spinal surgery in children often includes recombinant erythropoietin (rEPO) and antifibrinolytic therapapy (AFT). The aim of this study was to investigate the efficacy of intraoperative blood salvage in decreasing homologous blood transfusion. MATERIAL AND METHODS: using the prospective data from patients operated during a one year period for scoliosis correction, we calculate the predictable hematocrit at day postoperative 1 without the use of blood salvage and compare it to the target hematocrit transfusion according to patient's status...

In many computer vision and machine learning applications, the data sets distribute on certain low-dimensional subspaces. Subspace clustering is a powerful technology to find the underlying subspaces and cluster data points correctly. However, traditional subspace clustering methods can only be applied on data from one source, and how to extend these methods and enable the extensions to combine information from various data sources has become a hot area of research. Previous multi-view subspace methods aim to learn multiple subspace representation matrices simultaneously and these learning task for different views are treated equally...

The aim of the present study was to examine the possible role of nicotinic acetylcholine receptors of the dorsal hippocampus (CA1 regions), the medial prefrontal cortex or the basolateral amygdala in the effect of acute or sub-chronic stress on nicotine-induced conditioned place preference. Our results indicated that subcutaneous administration of nicotine (0.2 mg/kg) induced significant conditioned place preference. Exposure to acute or sub-chronic elevated platform stress potentiated the response of an ineffective dose of nicotine...

Essential Tremor is the most common neurological movement disorder. This progressive disease causes uncontrollable rhythmic motions-most often affecting the patient's dominant upper extremity-that occur during volitional movement and make it difficult for the patient to perform everyday tasks. Medication may also become ineffective as the disorder progresses. For many patients, deep brain stimulation (DBS) of the thalamus is an effective means of treating this condition when medication fails. In current use, however, clinicians set the patient's stimulator to apply stimulation at all times-whether it is needed or not...

BACKGROUND: Worldwide, dermatophytic infections are running a chronic course either due to ineffective treatment or emerging drug resistance. In the past three decades, there has been an increase in incidence and non-responsiveness to conventional antifungals, which suggests that there is a need of antifungal sensitivity testing. AIMS: This study was aimed at identifying clinico-mycological pattern of dermatophytic infections in patients attending thedermatology outpatient department of a tertiary care hospital, and to obtain the sensitivity pattern of isolates against six commonly used oral antifungals (fluconazole, terbinafine, itraconazole, ketoconazole, griseofulvin and voriconazole)...

Regular transfusion and iron chelation are the current treatment of severe forms of thalassemia. As a result of this demanding supportive treatment, there are several unmet therapeutic needs. Due to a deeper understanding in the pathophysiology of thalassemia, new therapeutic strategies have been developed that are now in pre-clinical and clinical trials. Areas covered: Activin receptor ligand traps (luspatercept and sotatercept), drugs targeting ineffective erythropoiesis, showed encouraging results in Phase I and II clinical trials...

Glia over-stimulation associates with amyloid deposition contributing to the progression of central nervous system neurodegenerative disorders. Here we analyze the molecular mechanisms mediating microglia-dependent neurotoxicity induced by prion protein (PrP)90-231, an amyloidogenic polypeptide corresponding to the protease-resistant portion of the pathological prion protein scrapie (PrP(Sc)). PrP90-231 neurotoxicity is enhanced by the presence of microglia within neuronal culture, and associated to a rapid neuronal [Ca(++)] i increase...

Canalicular papillomatosis is a rare disorder characterized by a mass lesion arising from the epithelium as a stalk from one of the canalicular walls. Traditionally, they have been treated with an open canaliculotomy and excision biopsy with or without additional cryotherapy. A patient with upper canalicular squamous papillomas treated with dacryoendoscopy-guided transcanalicular intralesional and topical interferon alpha 2b is presented, and the ineffectiveness of interferons in this case is discussed.

The recent discoveries in the fields of pathogenesis and management of diabetic nephropathy have revolutionized the knowledge about this disease. Little was added to the management of diabetic nephropathy after the introduction of renin angiotensin system blockers. The ineffective role of the renin- angiotensin system blockers in primary prevention of diabetic nephropathy in type 1 diabetes mellitus necessitated the search for other early therapeutic interventions that target alternative pathogenic mechanisms...

BACKGROUND: Oral lichen planus is a chronic inflammatory disease of unknown etiology. It is characterized by notable heterogeneity in clinical presentation and behavior. MAIN OBSERVATIONS: We describe 3 patients with lichenoid lesions of the upper lip and upper anterior gingiva. These cases probably represent a clinical subtype of lichenoid lesions associated with microbial antigenicity and are characterized by persistency. All three patients had a long history of previous ineffective treatments and all three showed an excellent response to a combination of clarithromycin (2 x 250 mg/day) and prednisolone (15 mg/day)...

The relation between attention and consciousness has been a controversial topic over the last decade. Although there seems to be an agreement on their distinction at the functional level, no consensus has been reached about attentional processes being or not necessary for conscious perception. Previous studies have explored the relation of alerting and orienting systems of attention and conscious perception, but the impact of the anterior executive attention system on conscious access remains unexplored. In the present study, we investigated the behavioral interaction between executive attention and conscious perception, testing control mechanisms both at stimulus-level representation and after error commission...
