TiO2 nanoparticles (NPs) are well-known nanomaterials (NMs), widely used in cosmetics, solar cells, photo-catalysts and additives. Anatase and rutile are the two main crystalline phases of TiO2 NPs and have distinct electrical and optical properties. However, their relative toxicity to organisms is a current topic of debate. In this study, we synthesize both anatase NPs (TiO2-A) and rutile NPs (TiO2-R) with similar particle sizes (20-40nm), surface areas (51-52m(2)/g) and Zeta potentials (-13.4 to -13.7mV), and investigate their toxicity to macrophages...

BACKGROUND AND PURPOSE: New venues are currently being explored to predict disease progression in Parkinson's disease (PD), such as non-motor subtypes and models merging motor and non-motor symptoms (NMS). By involving a subgroup of 585 patients from the PRIAMO (Parkinson Disease Non-motor Symptoms) study, the present 24-month longitudinal prospective analysis aimed to demonstrate that urinary dysfunction is an early marker of higher motor and non-motor burden as well as lower health-related quality of life...

BACKGROUND: Malignant catatonia (MC) is a disorder consisting of catatonic symptoms, hyperthermia, autonomic instability, and altered mental status. Neuroleptic malignant syndrome (NMS) caused by antipsychotics is considered a variant of MC. Benzodiazepine (BZD) medications are safe and effective treatments providing rapid relief from MC. This case study reports a detailed clinical course of a case of MC associated with schizophrenia initially diagnosed as NMS that responded successfully to BZDs but not to dantrolene...

In this study, nanoporous titanate (NT) nanoparticle synthesized by the solvothermal method was used to modify polyamide layer of thin film composite membranes with the aim of improving membrane resistances against organic and inorganic fouling. Thin film nanocomposite membranes (NMs) were synthesized by adding mNTs (modified nanoparticles) into polyamide selective layer followed by characterization using different analytical instruments. The results of XPS and XRD confirmed the presence of mNTs in the polyamide layer of NMs, while FESEM, AFM, zeta potential and contact angle measurement further supported the changes in physical and chemical properties of the membrane surface upon mNTs incorporation...

Nanomaterials (NM) exhibit novel physicochemical properties that determine their interaction with biological substrates and processes. Recent nano-technological advances are leading to wide usage of metallic nanoparticles (NPs) in various fields. However, the increasing use of NPs has led to their release into environment and the toxicity of NPs on human health has become a concern. Moreover, there are inadvertently generated metallic NPs which are formed during various human activities (e.g. metal processing and energy production)...

Neuromedin U (NMU) is a neuropeptide found in the brain and gastrointestinal tract. The NMU system has been shown to regulate energy homeostasis by both a central and a peripheral mechanism. Peripheral administration of human NMU-25 was recently shown to inhibit food intake in mice. We examined the possibility that other NMU-related peptides exert an anorectic activity by intraperitoneal (i.p.) administration. We found that rat NMU-23 and its structurally-related peptide rat neuromedin S (NMS) significantly reduced food intake in lean mice, whereas NMU-8, an active fragment of the octapeptide sequence conserved in porcine, human and mouse NMU, had no effect...

OBJECTIVE: To describe the presentation of neuroleptic malignant syndrome (NMS) and malignant catatonia (MC) in children and adolescents. BACKGROUND: NMS and MC are life-threatening, neuropsychiatric syndromes, associated with considerable morbidity and mortality. NMS is diagnosed when there is a recent history of treatment with an antipsychotic (AP) medication, while MC is diagnosed when the symptoms resemble NMS but without a history of exposure to an AP agent...

BACKGROUND: Non-motor symptoms (NMS) are extremely common among late-stage Parkinson's disease (LSPD) patients. Levodopa (L-dopa) responsiveness seems to decrease with disease progression but its effect on NMS in LSPD still needs to be investigated. OBJECTIVE: To assess the response of blood pressure (BP), pain, fatigue and anxiety to L-dopa in LSPD patients. METHODS: 20 LSPD patients, defined as Schwab and England ADL Scale <50 or Hoehn Yahr Stage >3 (MED ON) and 22 PD patients treated with subthalamic deep brain stimulation (advanced PD group) underwent an L-dopa challenge...

Neuromedin S (NMS) has been identified as an endogenous ligand for FM-3/GPR66 and FM-4/TGR-1 which are NMU receptors NMUR1 and NMUR2, respectively. The NMS molecule is present in some peripheral tissues and the central nervous system (CNS), and it had been documented that NMS has fundamental and important roles in multiple physiological functions and processes such as circadian rhythm, energy balance, feeding behavior, stress responses and reproduction. The possible role of NMS in sexual development postnatally, however, is still obscure...

Parkinson's disease (PD) prodromic stages comprise neuropsychiatric perturbations that critically compromise patient's quality of life. These non-motor symptoms (NMS) are associated with exacerbated innate immunity, a hallmark of overt PD. Physical exercise (PE) has the potential to improve neuropsychiatric deficits and to modulate immune network including receptors for advanced glycation endproducts (RAGE) and Toll-like receptors (TLRs) in distinct pathological settings. Accordingly, the present study aimed to test the hypothesis that PE i) alleviates PD NMS and ii) modulates neuroimmune RAGE-network in experimental PD...

Characterisation of engineered nanomaterials (NMs) is of outmost importance for the assessment of the potential risks arising from their extensive use. NMs display indeed a large variety of physico-chemical properties that drastically affect their interaction with biological systems. Among them, hydrophobicity is an important property that is nevertheless only slightly covered by the current physico-chemical characterisation techniques. In this work, we developed a method for the direct characterisation of NM hydrophobicity...

Bean (Phaseolus vulgaris) plants were grown for 45 days in soil amended with either uncoated (Z-COTE(®)) and coated (Z-COTE HP1(®)) ZnO nanomaterials (NMs), bulk ZnO and ZnCl2, at 0-500mg/kg. At harvest, growth parameters, chlorophyll, and essential elements were determined. None of the treatments affected germination and pod production, and only ZnCl2 at 250 and 500mg/kg reduced relative chlorophyll content by 34% and 46%, respectively. While Z-COTE(®) did not produce phenotypic changes, Z-COTE HP1(®), at all concentrations, increased root length (∼44%) and leaf length (∼13%) compared with control...

We present a case of 32-year-old male with profound mental retardation and autism spectrum disorder who had presented with seizures, rigidity and elevated creatine kinase and was initially diagnosed as neuroleptic malignant syndrome (NMS). The patient subsequently had a complicated clinical course, developing refractory status epilepticus, which lead to the eventual diagnosis of progressive encephalomyelitis with rigidity and myoclonus (PERM). We discuss the clinical similarities and differences between NMS and PERM, and highlight the need to consider alternative diagnoses when the clinical picture of NMS is atypical, particularly in this patient group where the history and clinical examination may be challenging...

Silicon (Si) nanomembranes (NMs) enable conformal covering on complicated surfaces for novel applications. We adopt classical fibers as flexible/curved substrates and wrap them with freestanding ultrathin Si-NMs with a thickness of ∼20 nm. Intrinsic defects in single-crystalline Si-NMs provide a flow path for hydrofluoric acid (HF) to release the NM with a consecutive area of ∼0.25 cm(2). Such Si-NMs with ultralow flexural rigidities are transferred onto a single-mode fiber (SMF) and functionalized into bendable photodetectors, which detects the leaked light when the fiber is bent...

Cancer has become a global problem. On all continents, a great number of people are diagnosed with this disease. In spite of the progress in medical care, cancer still ends fatal for a great number of the ill, either as a result of a late diagnosis or due to inefficiency of therapies. The majority of the tumors are resistant to drugs. Thus, the search for new, more effective therapy methods continues. Recently, nanotechnology has been attributed with big expectations in respect of the cancer fight. That interdisciplinary field of science creates nanomaterials (NMs) and nanoparticles (NPs) that can be applied, e...

The duration of action of oral levodopa becomes shorter as Parkinson's disease (PD) progresses. Patients with advanced PD may develop potentially disabling motor fluctuations and abnormal involuntary movement (dyskinesia), which cannot be managed with optimized oral or transdermal PD medications. The progressively worsening symptoms can have a substantial impact on the patient quality of life (QoL). Levodopa-carbidopa intestinal gel (LCIG) is delivered continuously via a percutaneous endoscopic gastrostomy with a jejunal extension (PEG-J)...
