Key Clinical Message: If you encounter an unexplained case of bone marrow edema in a young patient, consider the possibility of osteoid osteoma (OO). Even in the presence of a nidus near vital structures, RFA can safely be used to treat OO. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Adenoid cystic carcinoma (ACC) is an uncommon malignancy of head and neck. Although the cornerstone of treatment is surgery, concurrent chemoradiotherapy (CRT) might be used as an effective treatment for unresectable tumors. Herein we report a case of massive ACC of base of tongue with durable complete response to definitive CRT. Adenoid cystic carcinoma (ACC) is a rare tumor accounting for 1% of all head and neck cancers. The best treatment option is complete surgical resection with or without adjuvant radiotherapy. When surgical resection is not feasible, definitive radiotherapy with or without concurrent chemotherapy can be considered. Herein we report a non‐smoker 72‐year‐old woman presented with throat discomfort and sensation of a lump. Evaluation revealed an unresectable adenoid cystic carcinoma of the base of tongue in whom complete clinical response was achieved after definitive concurrent chemoradiation. Although the cornerstone of treatment is complete surgical resection, this case report indicates that concurrent chemoradiotherapy might result in complete clinical response and could be used as a definitive treatment in selected ACC tumors.

Key Clinical Message: Placenta previa, accompanied by placenta percreta, which involves invasion of the bladder, presents a significant risk of excessive bleeding during and after delivery. This case highlights that prophylactic embolization, conservative surgery, and careful monitoring offer an effective approach to avoid hysterectomy in cases of placenta percreta with adjacent organ involvement. Placenta previa complicated by placenta percreta is associated with a high risk of massive intra and post‐partum hemorrhage. We present a case of a 35‐year‐old woman (G2 P1) who was referred to the Akbar‐Abadi hospital at 13 weeks of gestation. Color Doppler ultrasound indicated complete placenta previa‐percreta with bladder invasion. After induction of fetal demise, bilateral uterine and bladder artery endovascular embolization was conducted for the patient. After 48 h, under ultrasound guidance, surgical resection of residual percreta tissue was conducted as much as possible. Eight weeks later, a follow‐up sonography showed the minimum residual placenta tissue and she regained menstrual cycles after 2 months. This case indicated that the combination of prophylactic embolization, conservative surgical management with placenta left in situ, and follow‐up with serial color Doppler monitoring, is an optimum method to avoid hysterectomy in placenta percreta patient with adjacent organ invasion.

This paper presents an improved switched‐inductor quasi‐Z‐source inverter with a higher boost factor than similar inverters, which integrates a switched‐capacitor and a three‐winding switched‐coupled inductor into a conventional quasi Z‐source inverter (q‐ZSI). The proposed inverter is called a switched‐capacitor trans quasi Z‐source inverter (SCT‐q‐ZSI). In this topology, the input current is continuous, and a high voltage gain is reachable with lowduty cycles (D). In this structure, capacitors are used instead of the side diodes of the switched‐inductor quasi Z‐source inverter. The proposed converter has a low inrush current at the startup which might damage the converter components. The performance of the proposed inverter is investigated at different operating modes and the voltage and current equations of all elements are calculated. The analysis, derivation of boost factor, capacitor voltages, and components, of the proposed inverter, are carried out and are compared with similar inverters. Finally, analytical, simulation, and experimental results are also presented to validate its advantages. [ABSTRACT FROM AUTHOR]

Migration of Ascaris lumbricoides through the papilla of Vater in humans, and entry into the biliary tree, is well‐recognised. Ascaris suum and Toxocara vitulorum have been recovered from the liver of swine and buffalo. We necropsied a Persian Kurdish filly at age 6 months, weighing ∼100 kg. Death evidently was caused by oleander (Nerium oleander) intoxication. An 8‐cm adult male Parascaris was found at the lobar‐left hepatic bile duct junction. We suggest that the nematode entered anteriorly into the hepatic tree, via the duodenum, major duodenal papilla, bile duct, left hepatic duct and finally the lobar duct. Considering the brief 4‐h elapsed time between death and necropsy, and the 18‐cm distance from the major duodenal papilla to the location of the parasite, we conclude that entry into the biliary tree likely occurred ante‐mortem. We advise consideration of Parascaris infection in differential diagnosis of equine hepatic and pancreatic dysfunction. [ABSTRACT FROM AUTHOR]

Pemphigus disease activity measurements: pemphigus disease area index, autoimmune bullous skin disorder intensity score, and pemphigus vulgaris activity score. Self-assessment Pemphigus Vulgaris Activity Score (SA-PVAS): A new tool for patients to self-assess their disease severity Pemphigus vulgaris (PV) is an autoimmune blistering mucocutaneous disease with an unpredictable course.1,2 For assessing the severity of PV, several scoring systems have been developed such as Pemphigus Disease Area Index (PDAI) and Pemphigus Vulgaris Activity Score (PVAS).3 We conducted this study to evaluate the translated simplified version of the PVAS called Self-Assessment PVAS (SA-PVAS) in comparison with the PDAI.

Two structures are proposed based on the quasi Z‐source inverter (qZSI), which can significantly raise the output voltage in applications, including photovoltaic and fuel cells, in which the input voltage is low. The proposed inverters provide a continuous input current and reduce the voltage stress on capacitor. Besides, the proposed switched‐capacitor‐inductor qZSI (SCL‐qZSI) can suppress inrush current at the start up moment as this current might damage the devices. The performance of the proposed structures is investigated at different operating modes, and the voltage equations are calculated. The voltage stress on switches, the voltage stress on capacitors, the voltage stress on diodes, and the current stress on inductor, as well as the average DC‐link current, the gain voltage (G), and the boost factor (B) of the proposed inverters, are analysed and derived. They are then compared with similar converters. To confirm the performance of the proposed converters, a laboratory sample of converters is made, which with output voltages, capacitors voltages, input and output current for the proposed converters. The DC‐link (Vi) voltage is 95 with boost factor 1.6 for SCL‐qZSI, and the DC‐link voltage is 216 with boost factor 3.6 for the enhance switched‐capacitor‐inductor qZSI (ESCL‐qZSI), which confirms the relationships obtained from the proposed converters. Also, the abbreviation for this paper is shown in table 1. [ABSTRACT FROM AUTHOR]

To investigate the effect of different levels of bioplex manganese along with probiotics and multi‐enzymes on the performance and immune system of broilers, 640 one‐day‐old male chicks of the Ross 308 strain were reared and the data analysed in a 4 × 2 × 2 factorial experiment with four levels of bioplex manganese (0, 60, 72 and 84 mg per kg of diet), two levels of Parsilact probiotic (0 and 200 mg per kg of diet) and two levels of Combo multi‐enzyme (0 and 1,000 mg per kg of diet) in a completely randomized design with 16 experimental treatments, 4 replicates and 10 chickens per replicate during a period of 42 days. The results showed that the performance of the broiler chickens in the diets containing 72 and 84 mg bioplex manganese along with probiotics and multi‐enzymes had the greatest difference compared to the control (p <.05). Compared to the control with 0 mg/kg manganese; the bursa of Fabricius weight was greater in chickens fed diets containing additional manganese (p <.05). The concentration of antibodies produced against Newcastle disease virus, as well as the concentrations of IgG, IgM and total immunoglobulins produced against SRBC, were highest in the group fed a diet containing 84 mg manganese along with probiotics and multi‐enzymes (p <.05). The results show combining additional manganese with probiotics and multi‐enzymes in chicken diets leads to better performance as well as a stronger immune system of chickens.

Background Clinical trials investigating the effects of addition of oxaliplatin to neoadjuvant radiochemotherapy in locally advanced rectal cancers (LARCs) have brought controversial results for pathologic complete response as an endpoint. This randomized clinical trial investigated downstaging as a short-term surrogate for progression-free survival (PFS). Methods Patients with magnetic resonance imaging (MRI) defined T3, T4 or N+ histologically proven adenocarcinoma of rectum within 15 cm from anal verge were randomly assigned to receive 50-50.4 Gy external beam radiation in 25-28 fractions and concurrent capecitabine 825 mg/m2 twice daily 5 days a week with or without oxaliplatin 60 mg/m2 weekly as neoadjuvant radiochemotherapy (Capox and Cap group, respectively). T downstage was defined as at least one stage regression in pathologic report after surgery comparing to MRI image before the preoperative treatment. Adverse effects of treatment were recorded on a weekly basis according to National Cancer Institute Common Toxicity Criteria, version 4. Results Sixty-three patients were randomly assigned to Cap ( n = 31) and Capox ( n = 32) groups. There was no grade 4 toxicity. The only grade 3 toxicity that occurred more in Capox group was diarrhea (22% vs 0%; P = 0.006). Histopathologic stage of 52 patients (27 patients in Cap and 25 patients in Capox groups) was compared to their preoperative stage defined by MRI. There was a greater rate of T downstage in Capox group (59% vs 42%; P = 0.037). Eleven patients in Capox group (34%) achieved pathologic complete response, comparing to four in Cap group (13%); P = 0.072. Conclusion The addition of oxalipatin to neoadjuvant radiochemotherapy in LARC led to higher rate of tumor downstaging. Longer follow-up is needed to evaluate PFS. [ABSTRACT FROM AUTHOR]

ABSTRACT We report on the utilization of an ultrathin buffer layer at the organic/organic (O/O) interface to enhance device efficiency in organic light-emitting diodes. Two different kinds of buffer layers are examined: metal and dielectric. It is shown that employment of an ultrathin Ag layer with a thickness of 1-2 nm enhances the device performance, while a MgF2 dielectric buffer cannot affect the device properties considerably. In particular, the turn-on voltage of the device with an appropriate buffer layer is reduced about 3 V, its current efficiency increases by a factor of more than three, and the power efficiency increases by a factor of more than five in comparison to the control device when a Ag buffer layer is introduced at the O/O interface. By employment of the buffer layer at the interface, an accumulation of current carriers appears within the device that redistribute the recombination profile toward the interior part of the emissive layer. Also, morphological examinations reveal that distinguishable phase segregation occurs in the blend of the hole-transport layer. In particular, the polymer component remains at the surface and facilitates the hole transport into the successive layers. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43894.

In this study, a new systematic approach is proposed to design the fuzzy controller for a class of Takagi–Sugeno fuzzy‐partial differential equation (TS fuzzy‐PDE) systems which describe the non‐linear distributed parameter system formulated by first‐order semi‐linear hyperbolic PDEs. In this study, non‐quadratic Lyapunov function is utilised and some slack matrices are introduced to derive stability conditions in terms of linear matrix inequalities (LMIs). The proposed approach has three main features. First, stability conditions are not derived in the form of spatial differential LMI. Second, conservativeness of LMI conditions is reduced. Third, there is no restriction on the form of semi‐linear hyperbolic PDE systems and therefore more semi‐linear systems classes can be stabilised. Also, the proposed approach is more suitable for practical implementation compared with the recently published papers. [ABSTRACT FROM AUTHOR]
