After a mean follow-up of 24 (range, 4-63) months, only 1 patient (4.5%) developed a recurrence, which was treated successfully with endoscopic resection. Complications included 1 patient with preoperative epiphora who required dacryocystorhinostomy, epistaxis in another, and 1 patient with transient upper lip numbness. No patients developed alar notching or pyriform aperture stenosis. CONCLUSION The MED technique is highly effective for surgical resection of primary and recurrent maxillary IPs involving the anterior wall, providing complete access to the entire maxillary sinus. In many cases, the MED can obviate the need for an adjunctive sublabial or transseptal incision, while also providing excellent exposure for postoperative surveillance. © 2020 ARS-AAOA, LLC.Pancreatic cancer is one of the most fatal malignancies with high mortality. Gemcitabine (GEM)-based chemotherapy is the most important treatment. However, the development of GEM resistance leads to chemotherapy failure. Previous studies demonstrated the anticancer activity of ginsenoside Rg3 in a variety of carcinomas through modulating multiple signaling pathways. In the present study, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay, colony formation assay, flow cytometry apoptosis assay, Western blotting assay, xenograft experiment, and immunohistochemistry assay were performed in GEM-resistant pancreatic cancer cell lines. Ginsenoside Rg3 inhibited the viability of GEM-resistant pancreatic cancer cells in a time-dependent and concentration-dependent manner through induction of apoptosis. The level of long noncoding RNA cancer susceptibility candidate 2 (CASC2) and PTEN expression was upregulated by the ginsenoside Rg3 treatment, and CASC2/PTEN signaling was involved in the ginsenoside Rg3-induced cell growth suppression and apoptosis in GEM-resistant pancreatic cancer cells. Ginsenoside Rg3 could be an effective anticancer agent for chemoresistant pancreatic cancer.

A 3D macroporous microbial biomat formed of Trichoderma viride immobilized on luffah was used for lead removal. The biomat was pre-treated using gamma irradiation, the morphology, elemental analysis of surface biosorbed lead and surface functional groups of control and pre-treated biomat were studied using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX) and Fourier Transform Infrared (FT-IR) spectroscopy. The biomat removed 89.05% under optimized conditions in 24 h. Removal was increased 1.6 fold within 1 h after microbial biomats were exposed to 0.01 KGy gamma radiation. The biomat was re-used efficiently for three consecutive cycles and was also used in fixed bed column showing 89% removal for downward flow and in real aquaculture sample. Pre-treated microbial biomats are very suitable for use in fixed bed reactors or as a biofilter and can be tested in Recirculating Aquaculture Systems (RAS) therefore contributing to water conservation and aquaculture sustainability.

The purpose of the study was to compare the distribution of photodermatoses between Whites and Blacks at four academic medical centers in the USA. METHODS A retrospective chart review was performed at four institutions' general dermatology clinics using diagnoses consistent with the International Classification of Disease (ICD), Ninth and Tenth Revisions, codes related to photodermatoses between August 2006 and August 2016. A total of 9736 charts were manually reviewed and classified. Analyses were performed analyzing the frequency of photodermatoses between Whites and Blacks in the pooled data. RESULTS There were 1,080 patients with photodermatoses identified. Statistically significant differences in the frequency of photodermatoses between Whites and Blacks were identified for polymorphous light eruption (more common in Blacks), photoallergic contact dermatitis, phototoxic drug eruption, phytophotodermatitis, porphyria, and solar urticaria (more common in Whites). The most commonly diagnosed photodermatoses were polymorphous light eruption (total 672), and photodermatitis not otherwise specified (total 189). CONCLUSION Our study demonstrated significantly higher proportions of polymorphous light eruption in Blacks, and higher proportions of photoallergic contact dermatitis, phototoxic drug eruptions, phytophotodermatitis, porphyrias, and solar urticaria in Whites. © 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.Doped p-n junctions are fundamental electrical components in modern electronics and optoelectronics. Due to the development of device miniaturization, the emergence of two-dimensional (2D) materials may initiate the next technological leap toward the post-Moore era owing to their unique structures and physical properties. The purpose of fabricating 2D p-n junctions has fueled many carrier-type modulation methods, such as electrostatic doping, surface modification, and element intercalation. Here, by using the nonvolatile ferroelectric field polarized in the opposite direction, efficient carrier modulation in ambipolar molybdenum telluride (MoTe2 ) to form a p-n homojunction at the domain wall is demonstrated. The nonvolatile MoTe2 p-n junction can be converted to n-p, n-n, and p-p configurations by external gate voltage pulses. Both rectifier diodes exhibited excellent rectifying characteristics with a current on/off ratio of 5 × 105 . As a photodetector/photovoltaic, the device presents responsivity of 5 A W-1 , external quantum efficiency of 40%, specific detectivity of 3 × 1012 Jones, fast response time of 30 µs, and power conversion efficiency of 2.5% without any bias or gate voltages. The MoTe2 p-n junction presents an obvious short-wavelength infrared photoresponse at room temperature, complementing the current infrared photodetectors with the inadequacies of complementary metal-oxide-semiconductor incompatibility and cryogenic operation temperature. © 2020 WILEY-VCH Verlag GmbH & Co.
