xlomafota13 shared this article with you from Inoreader Anterior Palatoplasty With Expansion Sphincter Pharyngoplasty for All Type of Pharyngeal Collapse Via The Laryngoscope Objectives/Hypothesis This study was aimed to compare the efficiency of the anterior palatoplasty and expansion sphincter pharyngoplasty (APwESP) technique for all patterns of velopharyngeal obstruction (anterior–posterior [APPC], lateral [LPC], or combined circular pharyngeal collapse [CPC]). Study Design The study was designed as a randomized prospective trial at Kâtip Çelebi University, Atatürk Training, and Research Hospital. Methods Patients only with velopharyngeal obstruction were included. Three groups were created according to the obstruction pattern (APPC, LPC, and CPC) for the study. Outcome parameters included patient's demographics, apnea-hypopnea index (AHI), lowest oxygen saturation (LOS), Stanford subjective scale of snoring (SSSS), and Epworth sleepiness scale (ESS). Results Thirty-one (34.1%) patients were in APPC group, while 30 (33.0%) patients were in LPC, and 30 (33.0%) were in CPC group. Preoperatively for all patients, on average, AHI was 33.4 ± 13.6, SSSS was 8.3 ± 1.0, ESS was 16.5 ± 2.6, and LOS was determined as 85.5 ± 3.6. There was a significant postoperative improvement in all parameters for all patients. There was no significant difference in outcome parameters between the groups according to obstruction pattern postoperatively. After APwESP surgery, obstruction pattern was not a significant factor for AHI (P = .234), SSSS (P = .180), and LOS (P = .280) (repeated measure analysis of variance test). The rate of surgical success was detected similarly for both of the study groups (P = .435). The rate of successful surgery for severe obstructive sleep apnea in the APPC group was 72.2%, 88.2% in the LPC group, and 75.0% in the CPC group (P =& nbsp;.472). Conclusion A combination of APwESP surgery can manage all types of pharyngeal obstruction confidently. Level of Evidence 3 Laryngoscope, 2021 View on the web Inoreader.

Improving the estimation accuracy of multi-nuclide source term estimation method for severe nuclear accidents using temporal convolutional network optimized by Bayesian optimization and hyperband

xlomafota13 shared this article with you from Inoreader Improving the estimation accuracy of multi-nuclide source term estimation method for severe nuclear accidents using temporal convolutional network optimized by Bayesian optimization and hyperband Via radioactive iodine J Environ Radioact. 2022 Feb;242:106787. doi: 10.1016/j.jenvrad.2021.106787. Epub 2021 Dec 4. ABSTRACT During a nuclear accident, estimating the source terms using environmental measurements is vital for emergency decision-making. In this study, we propose a forecasting model based on a temporal convolutional network to estimate the release rates of seven radionuclides (Kr-88, Te-132, I-131, Xe-133, Cs-137, Ba-140, and Ce-144) based on off-site sequential gamma dose rates and meteo rological monitoring data. To determine the best structure of the neural network, Bayesian optimization and hyperband (BOHB) was used on the hyperparameters of the model to reduce the testing loss. Additionally, a gradient boosting regression model was used to predict missing gamma dose rates to ensure the model offers a relatively reliable estimate under certain circumstances. The international radiological assessment system (InterRAS) was used to generate datasets for model training and testing. The results showed that the optimal hyperparameters selected by BOHB can reduce the valid loss of the model to 0.0153, and the mean absolute percentage error of prediction for the seven radionuclides was below 12%, three of which (Kr-88, Te-132, Cs-137) reached 8% at 10 h. When the first and second time-steps of the data were missing, the mean absolute percentage error of the prediction for all radionuclides was less than 30% after using a gradient boosting regression.

Paeonol suppresses lipid formation and promotes lipid degradation in adipocytes

xlomafota13 shared this article with you from Inoreader Paeonol suppresses lipid formation and promotes lipid degradation in adipocytes Via Experimental and therapeutic medicine Exp Ther Med. 2022 Jan;23(1):78. doi: 10.3892/etm.2021.11001. Epub 2021 Nov 25. ABSTRACT Paeonol can regulate a variety of physiological and pathological processes such as thrombosis, oxidative stress, inflammation and atherosclerosis. However, its potential role and underlying mechanisms in obesity and lipid metabolism remain to be elucidated. In the present study, 3T3-L1 cells were differentiated and collected on days 4, 6 and 8. The expression levels of fatty-acid-binding protein 4 (FABP4) and microRNA (miR)-21 were detected using reverse transcription-quantitative PCR and western blot analyses. Cell viability was assessed using a Cell Counting Kit-8 assay. A miR-21 mimic was constructed and transfected into 3T3-L1 preadipocytes. Adipocyte differentiation was detected using Oil Red O staining. The proteins CD36, glucose transporter 4, peroxisome proliferator-activated receptor γ (PPAR-γ) and adipocyte protein 2 (Ap2) were detected using western blot analysis. The expression levels of FABP4 and miR-21 were increased in differentiated 3T3-L1 cells. Paeonol exhibited no effects on cell activity, whereas it inhibited the expression levels of miR-21 in the 3T3-L1 differentiated adipocytes. Paeonol suppressed the differentiation of 3T3-L1 adipocytes and its effect was partially reversed by the overexpression of miR-21. In addition, paeonol promoted the lipid degradation of 3T3-L1 adipocytes, increased the expression levels of PPAR-γ and Ap2, and suppressed triglyceride synthesis in these cells. These effects were partially reversed by the overexpression of miR-21. In conclusion, the findings of the present study indicated that paeonol may exert protective effects against lipid formation and promote lipid degradation in adipocytes. These data provide evidence of the regulatory effect of paeonol on adipocyte differentiation and highlight its pathological significance.

Role and mechanism of the Dectin-1-mediated Syk/NF-κB signaling pathway in Talaromyces marneffei infection

xlomafota13 shared this article with you from Inoreader Role and mechanism of the Dectin-1-mediated Syk/NF-κB signaling pathway in <em>Talaromyces marneffei</em> infection Via Experimental and therapeutic medicine Exp Ther Med. 2022 Jan;23(1):84. doi: 10.3892/etm.2021.11007. Epub 2021 Nov 25. ABSTRACT Dendritic cell-associated C-type lectin-1 (Dectin-1), a C-type lectin receptor, serves a critical role in host antifungal immunity. However, the molecular mechanism and function of Dectin-1-mediated signaling in response to infection by the pathogenic fungus Talaromyces marneffei remains unclear. To understand the role of Dectin-1 signaling against T. marneffei infection, the phosphorylation of spleen tyrosine kinase (Syk), nuclear factor of κ light polypeptide gene enhancer in B-cells inhibitor, α (IκBα) and NF-κB were analyzed using western blotting, and the secretion of cytokines was detected using ELISA. Upon sporular or hyphal heat-killed T. marneffei stimulation, Dectin-1 in THP-1 macrophages recognized and induced the activation of Syk, and in turn triggered phosphorylation of downstream molecules IκBα and NF-κB, thus increasing the secretion of TNF-α and IL-8. Conversely, knockdown of Dectin-1 in THP-1 macrophages downregulated the phosphorylation of Syk, IκBα and NF-κB molecules, and significantly decreased the production of TNF-α and IL-8. These results indicated that Dectin-1 may have a crucial role in inducing the inflammatory response via increasing levels of TNF-α and IL-8 induced by T. marneffei, whereas NF-κB may be the key downstream molecule involved in the response to T. marneffei infection. Subsequently, THP-1 macrophages could orchestrate the innate immune system by releasing the cytokines TNF-α and IL-8. Therefore, it was hypothesized that regulation of the Dectin-1 signaling pathway may effectively interfere with the defense ability of the host against T. marneffei infection.

Physical Therapy for Muscle Tension Dysphonia with Cervicalgia

xlomafota13 shared this article with you from Inoreader Physical Therapy for Muscle Tension Dysphonia with Cervicalgia Via ear nose throat Ear Nose Throat J. 2021 Dec 23:1455613211063239. doi: 10.1177/01455613211063239. Online ahead of print. ABSTRACT OBJECTIVES: This study investigated the effectiveness of a specialized manual physical therapy (PT) program at improving voice among patients diagnosed with concomitant muscle tension dysphonia (MTD) and cervicalgia at a tertiary care voice center. MATERIALS AND METHODS: Cervicalgia was determined by palpation of the anterior neck. Both voice therapy (VT) an d PT was recommended for all patients diagnosed with MTD and cervicalgia. PT included full-body manual physical therapy with myofascial release. Patients underwent: 1) VT alone, 2) concurrent PT and VT (PT with VT), 3) PT alone, 4) VT, but did not have PT ordered by treating clinician (VT without PT order) or 5) VT followed by PT (VT then PT). The pairwise difference in post-Voice Handicap Index-10 (VHI-10) controlling for baseline variables was calculated with a linear regression model. RESULTS: 178 patients met criteria. All groups showed improvement with treatment. The covariate-adjusted differences in mean post-VHI-10 improvement comparing the VT alone group as a reference were as follows: PT with VT 9.95 (95% confidence interval 7.70, 12.20); PT alone 8.31 (6.16, 10.45); VT without PT order 8.51 (5.55, 11.47); VT then PT 5.47 (2.51, 8.42). CONCLUSION: Among patients diagnosed with MTD with cervicalgia, treatment with a specialized PT program was associated with impr ovement in VHI-10 scores regardless of whether they had VT. While VT is the standard of care for MTD, PT may also offer benefit for MTD patients with cervicalgia. PMID:34939450 | DOI:10.1177/01455613211063239 View on the web Inoreader.

Intracorporeal Cortical Telemetry as a Step to Automatic Closed-Loop EEG-Based CI Fitting: A Proof of Concept

xlomafota13 shared this article with you from Inoreader Intracorporeal Cortical Telemetry as a Step to Automatic Closed-Loop EEG-Based CI Fitting: A Proof of Concept Via cortical auditory Audiol Res. 2021 Dec 13;11(4):691-705. doi: 10.3390/audiolres11040062. ABSTRACT Electrically evoked auditory potentials have been used to predict auditory thresholds in patients with a cochlear implant (CI). However, with exception of electrically evoked compound action potentials (eCAP), conventional extracorporeal EEG recording devices are still needed. Until now, built-in (intracorporeal) back-telemetry options are limited to eCAPs. Intracorporeal recording of auditory responses beyond the cochlea is still lacking. This study describes the feasibility of obtaining longer latency cortical responses by concatenating interleaved short recording time windows used for eCAP recordings. Extracochlear reference electrodes were dedicated to record cortical responses, while intracochlear electrodes were used for stimulation, enabling intracorporeal telemetry (i.e., without an EEG device) to assess higher cortical processing in CI recipients. Simulta neous extra- and intra-corporeal recordings showed that it is feasible to obtain intracorporeal slow vertex potentials with a CI similar to those obtained by conventional extracorporeal EEG recordings. Our data demonstrate a proof of concept of closed-loop intracorporeal auditory cortical response telemetry (ICT) with a cochlear implant device. This research breaks new ground for next generation CI devices to assess higher cortical neural processing based on acute or continuous EEG telemetry to enable individualized automatic and/or adaptive CI fitting with only a CI.

Resection of the internal carotid artery in selected patients affected by cancer of the skull base

xlomafota13 shared this article with you from Inoreader Resection of the internal carotid artery in selected patients affected by cancer of the skull base Via Head & Neck Abstract Invasion of the internal carotid artery (ICA) has been historically considered a criterion of non-resectability of skull base cancer (SBC). Patients affected by SBC who underwent surgery including resection of ICA at two tertiary institutions were included. Demographics, oncologic, and surgical information, complications, and survival outcomes were retrospectively reviewed. Survival outcomes were calculated. Ten patients were included. Three surgical approaches (transnasal endoscopic, transorbital, and transpetrosal) were employed to resect the invaded/abutted tract(s) of the ICA. All patients underwent ICA temporary balloon occlusion test. In two patients, an extracranial-to-intracranial arterial bypass was harvested. Major neuromorbidity was observed in two patients. Perioperative mortality of the series was 10.0%. Mean overall survival was 27.2 months, with 2-year overall and progression-free survival rate of 88.9%. ICA resection is feasible as part of the ablation perform ed for very advanced SBCs. Survival outcomes are acceptable in adequately selected patients. View on the web Inoreader.
