Ethylene glycol is a common alcohol found in many household products such as household hard surface cleaner, paints, varnish, auto glass cleaner and antifreeze. While extremely toxic and often fatal on ingestion, few cases with early presentation by the patient have resulted in death; thus, rapid diagnosis is paramount to effectively treating ethylene glycol poisoning. In this study, we compare two sequential cases of ethylene glycol poisoning in a single individual, which resulted in strikingly different outcomes...

Three novel organic vermiculites (VER) modified by amphoteric surfactants (BS, SB and PBS) with different negatively charged groups (carboxylate, sulfonate and phosphate) were demonstrated and used for removal of bisphenol A (BPA) and tetrabromobisphenol A (TBBPA). The difference in the structure and surface properties of modified vermiculites were investigated using a series of characterization methods. BS and SB surfactant mainly adsorbed on the surface and hard to intercalate into the interlayer of VER, while both adsorption and intercalation occurred in PBS modification...

The hamstrings are seen to work during late swing phase (presumably to decelerate the extending shank) then during stance phase (presumably stabilizing the knee and contributing to horizontal force production during propulsion) of running. A better understanding of this hamstring activation during running may contribute to injury prevention and performance enhancement (targeting the specific role via specific contraction mode). Twenty active adult males underwent surface EMG recordings of their medial and lateral hamstrings while running on a reduced gravity treadmill...

BACKGROUND: It is a great challenge for pathologists to initially diagnose metastatic malignant mesothelioma (MM) by the lymph node biopsy without any history of primary MM. Because the onset of MM is hidden and the metastatic MM in lymph node is relatively uncommon. Besides, morphologic and immuohistochemistry features of MM are similar to other tumors. METHODS: In order to improve the initial diagnostic accuracy of metastatic MM from LN biopsy and to reduce or avoid the possibility of missed diagnosis or misdiagnosis, we had collected the clinical and pathological data of the metastatic MM cases in our department, and summarized the characteristics of morphological, immunohistochemical and fluorescence in situ hybridization (FISH) results...

Freeze dried raw (FDR) and freeze dried blanched (FDB) Amorphophallus paeoniifolius flours were irradiated at doses of 3, 6 and 12kGy. The irradiated flours were investigated for physicochemical, pasting, textural, thermal and morphological properties. Reduction in amylose content was observed with increasing irradiation dose. Carboxyl content of the flours increased significantly at higher doses. Decline in lightness (L(∗)) and increase in redness (a(∗)) were found to increase with the elevation of dosage...

This study assessed the slip resistance of different types of solid flooring in cattle housing using a range of technical tests and gait analysis. Dynamic and static coefficient of friction, skid resistance, and abrasiveness were tested on concrete flooring with a smooth finish, a grooved pattern, or a tamped pattern, acid-resistant mastic asphalt, soft rubber mats, and a worn slatted concrete floor. Coefficients of friction and skid resistance were tested under clean and slurry-soiled conditions. Linear kinematic variables were assessed in 40 cows with trackway measurements after the cows passed over the floors in a straight walk...

OBJECTIVE: Cervicogenic headache affects a significant portion of the entire population. This type of headache especially with atypical presentation is often hard to diagnose and manage since its etiopathophysiology is not been yet well understood. We have investigated the prevalence of cervicogenic headache with atypical presentation and discussed the etiology of it, and the outcome of surgical intervention on this type of headache in patients with cervical degenerative disease. PATIENTS AND METHODS: Radiological and clinical data of 160 patients (from 2001 through 2016) were retrospectively reviewed...

The resistivity versus temperature (ρ-T) behaviours of liquid n-type Bi2Te3-x Se x (x = 0.3, 0.45 and 0.6) alloys are explored up to 1050 °C. A clear hump is observed on all ρ-T curves of the three studied Bi2Te3-x Se x melts during the heating process, which suggests that a temperature-induced liquid-liquid structural transition takes place in the melts. Based on this information, the solidification behaviours and microstructures of the alloys with different liquid states are investigated. The samples that experienced liquid structural transition show that the nucleation and growth undercooling degrees are conspicuously enlarged and the solidification time is shortened...

A Salar Elahi, M Ghoranneviss
Plasma cooling due to hard x-ray radiation from the Runaway electrons is an important issue in tokamaks. Thus, developing effective methods to reduce the Runaway electrons and the emitted hard x-ray is also important for optimal tokamak plasma operation. In this study, we investigated the effects of external fields on hard x-ray intensity and the Magnetohydrodynamic (MHD) activity. In other words, we presented the effects of positive biased limiter and Resonant Helical Field (RHF) on the MHD fluctuations and hard x-ray emission from the Runaway electrons...

A rhizosphere Gram-positive bacterial isolate, Paenibacillus sp. NAIST15-1, exhibits intriguing motility behavior on hard agar media. Paenibacillus sp. shows increased transcription of flagellar genes and hyperflagellation when transferred from liquid to solid media. Hyperflagellated cells form wandering colonies that are capable of moving around on the surface of media containing ≥1.5% agar. Transposon mutagenesis was used to identify genes critical for motility. In addition to flagellar genes, this mutagenesis identified five non-flagellar structural genes that were important for motility...

In the present report, we discuss the case of a 66-year-old woman with isolated unilateral hypoglossal paralysis due to cerebral infarction in the centrum semiovale. To date, it has hardly been discussed where the corticolingual tract passes through in the centrum semiovale. Brain magnetic resonance imaging revealed a small ischemic infarction in the contralateral centrum semiovale. We could demonstrate a route of the corticolingual tract.

Lyme borreliosis is a vector-borne zoonosis caused by Borrelia burgdorferi sensu lato species complex spirochetes, which are maintained in transmission cycles among vertebrates and Ixodes ticks. Recently, a new genospecies within this complex, Borrelia chilensis, was described in Ixodes stilesi collected from the environment and from rodents in Chile. This tick also infests the native Southern pudu deer (Pudu puda). The objectives of this study were to investigate the prevalence, intensity of infestation, and aggregation of hard ticks on this deer species, and to determine the presence of borrelial pathogens in the ticks...

OBJECTIVE: When a new drug is marketed, physicians must decide whether they will consider it for their future practice. However, information about new drugs can be biased or hard to find. In this work, our objective was to study whether visual analytics could be used for comparing drug properties such as contraindications and adverse effects, and whether this visual comparison can help physicians to forge their own well-founded opinions about a new drug. MATERIALS AND METHODS: First, an ontology for comparative drug information was designed, based on the expectations expressed during focus groups comprised of physicians...

REVIEW
Yuw-Er Yong
Ricocheted bullets may still retain sufficient kinetic energy to cause gunshot injuries. Accordingly, this paper reviews the literature surrounding gunshot injuries caused by ricocheted bullets. In doing so, it discusses the characteristics of ricochet entrance wounds and wound tracks, noting several important considerations for assessment of a possible ricochet incident. The shapes of ricochet entrance wounds vary, ranging from round holes to elliptical, large and irregular shapes. Pseudo-stippling or pseudo-gunpowder tattooing, pseudo-soot blackening and tumbling abrasions seen on the skin surrounding the bullet hole are particularly associated with ricochet incidents...

BACKGROUND: Vertical bone augmentation (VBA) remains unpredictable and challenging for most clinicians. This study was aimed to compare hard tissue outcomes of VBA, with and without rhBMP-2, under space-making titanium mesh in a canine model. METHODS: Eleven male beagle dogs were used in the study. Experimental ridge defects were created to form atrophic ridges. VBA was performed via guide bone regeneration (GBR) using titanium mesh and allografts. In experimental hemimandibles, rhBMP-2/ACS was well mixed with allografts prior to procedures, whereas a control buffer was applied within controls...
