The asthma treatment and control might be associated with significant burden on family and community' thus exploring other therapeutic plans could be desirable. The aim of this study was to investigate the effect of salt space on clinical findings and peak expiratory flow rate among children with asthma. In this randomized crossover trial, 34 patients aged 6-14 years old with mild to moderate asthma were selected and randomly divided into two groups. The first group went through a period of salt therapy by staying in the salt room for one hour, three times a week for 3 consecutive weeks and then was under observation for three weeks...

The alignment of hexagonal boron-nitride nanotubes (BNNTs) in aqueous KCl solutions under spatially uniform electric fields was examined experimentally, using direct optical visualization to probe the orientation dynamics of individual BNNTs for different electric-field frequencies. Different from most previously studied nanowires and nanotubes, BNNTs are wide-bandgap materials which are essentially insulating at room temperature. We analyze the electro-orientation of BNNTs in the general context of polarizable cylindrical particles in liquid suspensions, whose behavior can fall into different regimes, including alignment due to Maxwell-Wagner induced dipoles at high frequencies, and alignment due to fluid motion of the electrical double layer around the particles at lower frequencies...

In this work, the performance of benzene, toluene, ethylbenzene, and xylene (BTEX) removal and degradation from gas, air streams on UV pretreated Fe-ZSM-5 in a batch reactor at room temperature were studied. The Fe-ZSM-5 zeolite catalyst was prepared by hydrothermal reaction method. The influence of UV pre-irradiation time on the removal of BTEX were assessed by varying the time, ranging from 15min to 60smin. Then, sustainability of the activation of the catalyst resulted by UV pretreatment was studied by the four-cycle experiment with one time UV irradiation and after each cycle irradiation followed by BTEX removal after every cycle respectively...

Reversible protein phosphorylation regulates virtually all aspects of life in the cell. As a result, dysregulation of protein kinases, the enzymes responsible for transferring phosphate groups from ATP to proteins, are often the cause or consequence of many human diseases including cancer. Almost three dozen protein kinase inhibitors (PKIs) have been approved for clinical applications since 1995, the vast majority of them for the treatment of cancer. According to the NCI, there are more than 100 types of cancer...

Single nanowire lasers based on bottom-up III-V materials have been shown to exhibit room-temperature near-infrared lasing, making them highly promising for use as nanoscale, silicon-integrable and coherent light sources. While lasing behavior is reproducible, small variations in growth conditions across a substrate arising from the use of bottom-up growth techniques can introduce inter-wire disorder, either through geometric or material inhomogeneity. Nanolasers critically depend on both high material quality and tight dimensional tolerances, and as such, lasing threshold is both sensitive to, and a sensitive probe of such inhomogeneity...

Ambient air pollution poses a significant risk for a group of common and often debilitating respiratory diseases, but its direct impact on cause-specific respiratory diseases using emergency room visit (ERV) as an indicator remains to be fully explored. In this study, we conducted a time-series study of ambient PM2.5, NO2, SO2 and their association with ERV for asthma, COPD and pneumonia in a four-year time span. Relative risks for ERV as per log increase in the level of ambient pollutants with time lags of up to 10 days were calculated, using a generalized additive model of Poisson regression...

We report a patient with diffuse peritonitis due to perforation of Meckel's diverticulum. This patient was referred to the operating room and underwent bowel resection segment encompassing the area of the diverticulum and terminoterminal primary enteroanastomosis on two levels with good evolution. The diverticulum complications are often related to the presence of ectopic mucosa, specially the gastric and pancreatic type. Since preoperative diagnosis is difficult and infrequent, in most cases this anomaly is confirmed only during surgery...

This paper examines inter-bureaucracy tension, negotiation, and resolution in the case of the oversight of beverage room sanitation in Ontario in the 1930s and 1940s. Both the Liquor Control Board of Ontario (LCBO) and various public health authorities claimed authority over the health status of public drinking spaces. But the LCBO had legislative priority. The ensuing debates regarding health and cleanliness linked issues of beverage room glass sanitation to a biopolitical approach to public drinking. Developing a more scientifically sophisticated approach to beverage glass cleaning required a balancing of administrative priorities...

BACKGROUND: The use of neonatal 3-lead electrocardiograms (Neo-ECG) is suggested as a method for the assessment of heart rate (HR) in neonatal resuscitation, but primary childbirth facilities (i.e., maternity clinics or maternity homes) are not sufficiently equipped for this. The objective of this study was to confirm the potential of using a handheld fetal Doppler device (FDD), widely used to assess HR in labor room resuscitation, and to compare its equivalency to Neo-ECG. METHODS: In low-risk full-term infants, HR was measured 5 times/minute in minutes 1-5 postpartum using the FDD and Neo-ECG, and their equivalence was compared...

Testing episodic foresight in children generally involves presenting them with a problem in one location (e.g., Room A) and, after a spending a delay in a different location, telling them they will be returning to Room A. Before they go, children are presented with a number of items, one of which will allow them to solve the problem in Room A. At around 3 to 4 years of age children display episodic foresight, selecting the item that will allow them to solve the problem. To date, however, no study has assessed whether 3- and 4-year-old children can plan beyond the very next event, selecting the correct item when there is a delay before returning to Room A...

OBJECTIVE The vascularized nasoseptal flap (NSF) has become the workhorse for skull base reconstruction during endoscopic endonasal surgery (EES) of the ventral skull base. Although infrequently reported, as with any vascularized flap the NSF may undergo ischemic necrosis and become a nidus for infection. The University of Pittsburgh Medical Center's experience with NSF was reviewed to determine the incidence of necrotic NSF in patients following EES and describe the clinical presentation, imaging characteristics, and risk factors associated with this complication...

We describe the use of dicyanoaurate ions as linear ditopic metal-organic acceptors for the halogen bond-driven assembly of a dichroic metal-organic cocrystal based on azobenzene chromophores. Structural analysis by single crystal X-ray diffraction revealed that the material is a four-component solid, consisting of anticipated anionic metal-organic halogen-bonded chains based on dicyanoaurate ions, as well as complex potassium-based cations and discrete molecules of the crown ether 15-crown-5. Importantly, the structural analysis revealed the parallel alignment of the halogen-bonded chains required for dichroic behaviour, confirming that crystal engineering principles developed for the design of halogen-bonded dichroic organic cocrystals are also applicable to metal-based structures...

A highly stable graphene-like metal-organic framework (BUC-17) was prepared and used as an adsorbent to carry out the adsorption of anionic dyes from simulated wastewater, which exhibited excellent adsorption performance, particularly towards Congo red (CR) up to 4923.7 mg g(-1) at room temperature. It was used to fix a SPE column to conduct rapid separation of anionic dyes from an organic dye matrix. A related mechanism was also proposed.

In the present Communication, we propose a quite simple but previously overlooked approach for conveniently analyzing, assigning, and extracting sialic acid-containing N-glycan structures using high-resolution NMR spectroscopy without pre-installing metal chelators. Paramagnetic metals, such as Gd(3+), appear to bind to the carboxyl groups of N-acetylneuraminic acid when introduced at room temperature, leading to the measurement of nonequivalent proton and carbon NMR spectral signals among otherwise "identical" glycan branched structures...

PURPOSE: The initial assessment of severely injured patients in the resuscitation room requires a systematic and quickly performed survey. Whereas the Advanced Trauma Life Support (ATLS(®))-based algorithm recommends focused assessment with sonography in trauma (FAST) among others, recent studies report a survival advantage of early whole-body computed tomography (WBCT) in haemodynamically stable as well as unstable patients. This study assessed the opinions of trauma surgeons about the early use of WBCT in severely injured patients with abdominal trauma, and abdominal CT in patients with isolated abdominal trauma, during resuscitation room treatment...

The pathogenesis of gastric cancer regardless of histological structure is a classic example of gene-environment interaction, and an important epidemiological aspect was the recognized association with Helicobacter pylori infection. This paper describes a case of gastric mucosa-associated lymphoid tissue (MALT) lymphoma in a young patient whose first sign of the disease was upper gastrointestinal bleeding and associated hemorrhagic shock. The patient is a 31-year-old man, diagnosed by endoscopy 10 years ago with H...

2-Bromo-N,N-diphenylacetamide (P1) prepared by reacting diphenylamine with α-bromoacetyl bromide, on treatment with Na2S and Na2Se generated in situ, has resulted in thio and selenoether ligands, L1 ((Ph2NCOCH2)2S) and L2 ((Ph2NCOCH2)2Se), respectively. Reacting these ligands with Na2PdCl4 in ethanol at room temperature resulted in their complexes [Pd(L1/L2)2Cl2] (C1/C2). P1, L1, L2, C1 and C2 were characterized by (1)H, (13)C{(1)H} and (77)Se{(1)H} NMR spectroscopy, IR spectroscopy and High resolution mass spectrometry (HR-MS)...
