Online ahead of print. ABSTRACT Development of high efficient adsorbents to capture iodine is of great significance for the active development of nuclear power. Herein, Bi0-SBA-15 was firstly synthesized and applied for capture of iodine gas. Bi0-SBA-15 materials were prepared by an improved impregnation reduction method. The benefit of this method was that the Bi0 nano particles with flocculent and spherical morphologies were loaded on the surface of SBA-15, which provide abundant active sites for iodine and improve the utilization rate of active sites, so as to attain a record high capture capacity (up to 925 mg/g within 60 min) and high stablitiy (91.2%) at 200 °C. The results demonstrated that the loading of Bi0 on the surface showed a significant impact on the structure of Bi0-SBA-15 and did greatly enhance the iodine capture. Furthermore, the high iodine capture capacity mainly derived from the chemical adsorption in the stable form of BiI3. The obtained Bi0-SBA-15 materials exhibited excellent aqueous and irradiation stability. Thus, the results indicated that the new and highly efficient Bi0-SBA-15 was a potential radioactive iodine gas capture material.

Localization of the neuropeptide manserin in rat dorsal root ganglia: Involvement in nociceptive function

xlomafota13 shared this article with you from Inoreader Localization of the neuropeptide manserin in rat dorsal root ganglia: Involvement in nociceptive function Via histochem Acta Histochem. 2021 Nov 11;123(8):151812. doi: 10.1016/j.acthis.2021.151812. Online ahead of print. ABSTRACT Manserin, a neuropeptide discovered in the rat brain, is distributed in the spiral ganglion of the inner ear and carotid body, suggesting it is also localized in another neuron cluster. In this study, we examined manserin's localization in the dorsal root ganglion (DRG) and spinal cord of adult Wistar rats using immunohistochemical analyses. The DRG consists of neuro filament (NF) 200-positive large cells and two types of small cells (calcitonin gene-related peptide (CGRP)-positive peptidergic neurons and isolectin B4 (IB4)-positive non-peptidergic neurons). Manserin was localized in some of the small cells. Fluorescence double immunostaining showed that manserin-positive cells corresponded to some of the CGRP-positive cells. The DRG comprises pseudo-unipolar cells that receive sensory information from the skin and viscera and project to each layer of the dorsal horn of the spinal cord. Manserin was localized in the CGRP-positive layer I and II outer, but not in the IB4-positive layer II inner. These results suggest manserin is localized in CGRP-positive cells in the DRG, projects to the dorsal horn of the spinal cord, and is secreted with other neuropeptides, such as CGRP, to participate in nociceptive function.

Head and neck research in plastic surgery-Ahead of the rest? An analysis of abstracts presented at British association of plastic reconstructive and aesthetic surgeons meetings

xlomafota13 shared this article with you from Inoreader Head and neck research in plastic surgery-Ahead of the rest? An analysis of abstracts presented at British association of plastic reconstructive and aesthetic surgeons meetings Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Oct 22:S1748-6815(21)00492-7. doi: 10.1016/j.bjps.2021.09.047. Online ahead of print. ABSTRACT INTRODUCTION & AIMS: Historically, the head and neck (H&N) discipline has been integral to the service a plastic surgeon provides. Recently, it has been postulated that its popularity is declining. The output of scientific meetings may indicate the popularity of each sub-speciality interest, also allowing comparison with other H&N conferences. AIM: To analyse the proportion of H&N themed, podium and poster presentations from British Association of Plastic Reconstructive and Aesthetic Surgeons' (BAPRAS) scientific meetings and the resulting contribution to published literature. MATERIAL AND METHODS: H&N-themed abstracts were identified from finalised programmes of the biannual BAPRAS meetings between 2008 and 2015. PubMed and Google Scholar databases were searched using keywor ds and author names from each abstract to identify subsequent publication in a peer-reviewed journal. RESULTS: Overall, 19.3% (350/1815) of BAPRAS abstracts were H&N themed. The publication rate of H&N abstracts was 40.3% (141/350), comprising 43.0% (114/265) of podium and 31.8% (27/85) of poster presentations. H&N reconstruction and cleft and craniofacial were the most frequent topics, with facial palsy having the lowest conversion rate at 15.4%. The mean time to publication was 17.8 months. Research was published in 39 journals, with a mean impact factor of 2.151 (range = 0.772-11.541). The most popular journal was Journal of Plastic, Reconstructive & Aesthetic Surgery (JPRAS; 31.7%; 45/141). Published abstracts originated from 17 different countries. The senior author was a plastic surgeon in 77.3% of abstracts. CONCLUSIONS: From the multiple potential sub-specialties, H&N-themed abstracts consistently contributed 20% of all research presented at B APRAS. The 40.3% publication rate exceeds the international average of scientific meetings. H&N remains a prominent field in the armamentarium of a plastic surgeon.

Online ahead of print. ABSTRACT Extraskeletal Ewing sarcoma (EES) is a relatively rare primary tumor of the soft tissues predominantly affecting men in the second and third decades of life. They are a less common form of the cancerous growth known as an Ewing sarcoma, which occurs in bones or soft tissue such as cartilage. Head and neck ESS can require intervention including endoscopic sinus sur gery, septoplasty, inferior turbinectomy, and left internal nasal valve repairs with septal cartilage This is a case report on an unusual presentation of ESS in the sinonasal region.

Am häufigsten betrifft sie die oberen Atemwege, die Lunge und die Nieren. Die Beschwerden sind unspezifisch, häufig beklagen die Patienten anfangs eine Nasenatmungsbehinderung, Borkenbildung in der Nase, Ulzera der Mundschleimhäute oder Epistaxis. Nicht selten wird deshalb der Hals-Nasen-Ohren-Arzt zu Beginn der Krankheit hinzugezogen. Langfristig können schwerwiegende kardiale, renale oder pulmonale Komplikationen auftreten. Die Ätiologie ist bis heute nicht komplett geklärt. Als Therapie wird eine Immunsuppres sion eingeleitet. Klinische und laborchemische Kontrollen sind lebenslang obligat.

SUVmax for predicting regional control in oropharyngeal cancer

xlomafota13 shared this article with you from Inoreader SUV<sub>max</sub> for predicting regional control in oropharyngeal cancer Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Nov 15. doi: 10.1007/s00405-021-07169-7. Online ahead of print. ABSTRACT PURPOSE: To investigate the predictive value of pretherapeutic metabolic tumor imaging using 18-fluorodeoxyglucose positron emission tomography (FDG-PET) for regional response in oropharyngeal cancer patients undergoing primary (chemo)radiation. METHODS: Retrospective analysis of oropharyngeal cancer patients treated with primary (chemo)radiation at the University Hospital Zurich from 2010 to 2019 with available FDG-PET. The SUVmax of the largest lymph node metastases was recorded. Regional response was assessed using posttherapeutic FDG-PET at 12 weeks and regional recurrence-free survival. RESULTS: 95 patients with a mean age of 68.5 years (SD 10.3) were included. The median pretherapeutic nodal SUVmax was 8.3 (interquartile range 4.4-13.3). A pretherapeutic nodal SUVmax above 6 signifi cantly predicted poorer regional recurrence-free survival (log-rank test, P = 0.009) in univariate analysis. However, in multivariate analysis SUVmax above 6 was not significant in predicting regional recurrence-free survival (Cox regression P = 0.189). Clinical N category showed a trend in which a more severe stage had a poorer regional survival (Cox regression P = 0.073). CONCLUSION: The SUVmax of the largest lymph node metastasis seems to play a role in predicting regional response in oropharyngeal cancer patients, after stratifying for N category. More research is needed to investigate whether highly metabolically active disease is less likely to respond to chemoradiation.
