Publication date: Available online 31 October 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Vahid Hoseinpour, Nasser GhaemiAbstractNanobiotechnology is a promising and appearing field of nanotechnology. In recent years, the necessity of making biocompatible materials for different applications in various area such as health, medicine, water treatment and purification, etc. caused more attention to this area. Today, green synthesis of different nanoparticles (NPs) has been extensively studied. However, less attention has been paid to manganese as a high-performance metal in various applications such as medicine, biomedicine, biosensors, water treatment and purification, electronics, electrochemistry, photoelectronics, catalysis, and etc. Manganese oxides (Mn-ox...

Regulation of ROS through proficient modulations of antioxidative defense system maintains the structural and functional integrity of photosynthetic apparatus and confers drought tolerance in the facultative halophyte Salvadora persica L.
Publication date: Available online 31 October 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Jaykumar Rangani, Ashok Panda, Monika Patel, Asish Kumar ParidaAbstractThe facultative halophyte Salvadora persica L. grow in arid, semiarid and saline areas. In present study, drought induced alterations in growth, ion homeostasis, photosynthesis, chlorophyll fluorescence, ROS regulation and antioxidative defense components were analyzed in S. persica with an aim to elucidate the drought tolerance mechanisms. In response to drought, significant reductions in growth, photosynthesis, and photosynthetic pigments were observed in S. persica. However, leaf relative water content (RWC %) did not change significantly. In S. persica seedlings, the growth, photosynthetic pigmen...

Is the Location of White Matter Lesions Important in the Swallowing Function of Older Patients with Mild Stroke?
AbstractOlder patients with stroke have poor functional prognosis compared to younger patients. Patients with stroke who have severe white matter (WM) lesions have been reported to have swallowing problems. The aim of this study was to determine whether the location of WM lesions affects swallowing function in older patients with mild stroke. We conducted a retrospective analysis of 88 patients aged > 65 years who had a National Institutes of Health Stroke Scale score of ≤ 5 and who underwent videofluoroscopic swallowing examination after their first stroke. Participants were divided into three groups according to the involvement of corticobulbar tract (CBT) as follows: group I, no inv olvement of CBT; group II, involvement of CBT in one hemisphere; and group III, involvem...

Irradiation by ultraviolet light-emitting diodes inactivates influenza a viruses by inhibiting replication and transcription of viral RNA in host cells
This study aimed to investigate how to inactivate IAVs by using different ultraviolet-light-emitting diodes (UV-LEDs). We developed sterilization equipment with light-emitting diodes (LEDs) those peak wavelengths were 365 nm (UVA-LED), 310 nm (UVB-LED), and 280 nm (UVC-LED). These UV-LED irradiations decreased dose fluence-dependent plaque-forming units of IAV H1N1 subtype (A/Puerto Rico/8/1934) infected Madin-Darby canine kidney (MDCK) cells, but the inactivation efficiency of UVA-LED was significantly lower than UVB- and UVC-LED. UV-LED irradiations did not alter hemagglutination titer, but decreased accumulation of intracellular total viral RNA in infected MDCK cells was observed. Additionally, UV-LED irradiations suppressed the accumulation of intracellular mRNA (messenger RNA), ...

An ultrasound study of contextual and syllabic effects in consonant sequences produced under heavy articulatory constraint conditions
Publication date: Available online 28 October 2018Source: Speech CommunicationAuthor(s): Daniel Recasens, Clara RodríguezAbstractThe present ultrasound study investigates lingual coarticulatory resistance and differences in tongue configuration and contextual variability for consonants in syllable onset vs coda position in Catalan /iC#Ci/ sequences. In agreement with comparable ultrasound data for /aC#Ca/ sequences reported in an earlier study, coarticulatory resistance turned out to be less for /r/ (which is realized as a trill in onset position and exhibits a more tap-like realization in coda position), /l/ (which is not strongly dark), /s/ and the alveolopalatal /ɲ/ than for /p, t, n, k/. As expected, contextual variability was less for /iC#Ci/ than for /aC#Ca/ sequences due to the hi...

Acquiring and visualizing 3D/4D ultrasound recordings of tongue motion
Publication date: November 2018Source: Journal of Phonetics, Volume 71Author(s): Steven M. Lulich, Kelly H. Berkson, Kenneth de JongAbstractUltrasound is increasingly common in speech and phonetics research as technology continues to improve. The first digital 3D/4D ultrasound system was utilized for speech research nearly a decade ago, but data access, processing, and visualization were limited to (non-speech) clinical imaging applications. Access to the raw (pulse-echo or scan-converted) image data is a critical step toward making 3D/4D ultrasound an effective tool for speech research. In addition, there is a need for technical characterization of 3D/4D ultrasound systems together with a presentation of their strengths and limitations for research. This paper gives a general technical de...

A modified multimodal communication treatment for individuals with traumatic brain injury.
In this study, the researchers measured the effectiveness of a modified Multimodal Communication Treatment designed to increase communication breakdown resolution and use of AAC strategies by two individuals with TBI. A multiple baseline, single-case design was used to measure outcomes for the two participants who had motor speech disorders and cognitive-communication impairments. They completed four pre-treatment sessions, 20 treatment sessions, and three post-treatment sessions. Dependent variables included the number of AAC strategies produced during a modality probe task and two measures of communication breakdown resolution during a structured, functional task. Both participants increased use of AAC strategies during modality probes, but demonstrated minimal changes in communication b...

The complexities of AAC intervention research: emerging trends to consider.
Authors: Romski M, Sevcik RA Abstract Augmentative and alternative communication (AAC) is always about intervening and the subsequent effects of the interventions (e.g., on the AAC user, family perspectives, educational outcomes, and vocational outcomes). AAC intervention research is about generating new knowledge by studying some aspect of AAC delivery in a planned manner so that it can be replicated and then translated into clinical/educational practice. This commentary on AAC intervention research highlights the complexities inherent in this type of research and the range of components that contribute to it, and reflects on emerging trends that we must consider as we continue to develop and enhance intervention research. Conducting AAC intervention research is a commitment to un...

Preoperative Vascular Interventions to Improve Donor Leg Perfusion: a Report of Two Fibula Free Flaps Used in Head and Neck Reconstruction
For the reconstruction of head and neck defects, the fibula free flap is the first choice at many institutions. The main contraindication for fibula harvest is the lack of three vessel run-off leading to post-operative vascular compromise of the lower extremity. Atherosclerosis is the most common disease which can limit the use of this donor site. In general, vascular interventions, which includes angioplasty, atherectomy, and stenting, have been utilized to fix the arterial supplies using endovascular methods.

Amyloidosis of the Upper Aerodigestive Tract: Management of a Rare Disease and Review of the Literature
AbstractAmyloidosis in the upper aerodigestive tract is a very rare disease with mainly case reports documented so far. In the pathogenesis, amyloid protein fibers are deposited in organs and tissue. In the upper aerodigestive tract, mostly localized amyloidosis occurs with unspecific symptoms, e.g., dysphagia. We conducted a retrospective multicenter study with two study centers in Germany (tertiary referral hospitals), the University Hospital of Bonn and the University Hospital of Goettingen. For a period of the last 7 years, data were analyzed and patients were recruited consecutively. 14 cases were included to the study. The most common manifestation was in the larynx (n = 11); in one case each localized amyloidosis was found in the tongue, trachea and in the pharynx. Since the maj...
