Epignathus is a rare congenital orofacial teratoma that arises from the sphenoid region of the palate or the pharynx. It occurs in approximately 1:35,000 to 1:200,000 live births representing 2% to 9% of all teratomas. We present the case of a newborn of 39.4 weeks of gestation with a tumor that occupied the entire oral cavity. The patient was delivered by cesarean section. Oral resection was managed by pediatric surgery. Plastic surgery used virtual 3-dimensional models to establish the extension, and depth of the tumor. Bloc resection and reconstruction of the epignathus were performed. The mass was diagnosed as a mature teratoma associated with cleft lip and palate, nasoethmoidal meningocele that conditions hypertelorism, and a pseudomacrostoma. Tridimensional technology was applied to plan the surgical intervention. It contributed to a better understanding of the relationships between the tumor and the adjacent structures. This optimized the surgical approach and outcome.
Phenolic–Protein Interactions: Effects on Food Properties and Health Benefits
Nydia E. Buitimea-Cantu´a,Janet A. Gutie´rrez-Uribe,Sergio O. Serna-Saldı´var 한국식품영양과학회 2018 Journal of medicinal food Vol.21 No.2
Phenolic–protein interactions (PPI), which naturally occur in most food systems, are being intentionally designed to enhance functional performance of phenolic compounds (PC). PPI have been primarily associated with changes related to sensorial, nutritional, and nutraceutical features of foods. Furthermore, these interactions affect properties such as astringency, protein digestibility, absorption, and bioavailability of antioxidants. Therefore, new product development should pay attention to these interactions and not only on the concentration of PC. PPI protect PC from degradation due to enzymatic attack or pH changes in the lumen of the intestinal tract. Due to PPI, PC are delivered to the colon where they are metabolized by the microbiota and generate an antioxidant environment. Interactions with proteins also may enhance the antiproliferative activity of PC in some specific tumor cell lines. In this review, the effects of PPI that affect both food properties and health benefits are discussed.
RNA design rules from a massive open laboratory

<P>Self-assembling RNA molecules present compelling substrates for the rational interrogation and control of living systems. However, imperfect in silico models—even at the secondary structure level—hinder the design of new RNAs that function properly when synthesized. Here, we present a unique and potentially general approach to such empirical problems: the Massive Open Laboratory. The EteRNA project connects 37,000 enthusiasts to RNA design puzzles through an online interface. Uniquely, EteRNA participants not only manipulate simulated molecules but also control a remote experimental pipeline for high-throughput RNA synthesis and structure mapping. We show herein that the EteRNA community leveraged dozens of cycles of continuous wet laboratory feedback to learn strategies for solving in vitro RNA design problems on which automated methods fail. The top strategies—including several previously unrecognized negative design rules—were distilled by machine learning into an algorithm, EteRNABot. Over a rigorous 1-y testing phase, both the EteRNA community and EteRNABot significantly outperformed prior algorithms in a dozen RNA secondary structure design tests, including the creation of dendrimer-like structures and scaffolds for small molecule sensors. These results show that an online community can carry out large-scale experiments, hypothesis generation, and algorithm design to create practical advances in empirical science.</P>
Vertically-Aligned ZnO/InxSy Core-Shell Nanorods for High Efficient Dye-Sensitized Solar Cells

Innovative vertically aligned ZnO/InxSy nanorod (NR) electrodes were prepared by successive ion layer adsorption and reaction (SILAR) technique. The InxSy shell layer was deposited on top of ZnO NR electrodes of two different lengths, ~ 1.6 µm and ~ 3.2 µm. Two sulfur contents on the InxSy shell layer with different layer thicknesses were analyzed. These electrodes were fully characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction spectroscopy (XRD), Energy-dispersive x-ray spectroscopy (EDS), Infrared spectroscopy (FT-IR), x-ray photoelectron spectroscopy (XPS) and ultraviolet photoemission spectroscopy (UPS) and then applied in dye-sensitized solar cells (DSC). Power conversion efficiency of 2.32% was observed when a low-sulfur content InxSy shell layer was applied in comparison to the stoichiometric In2S3 shell layer (0.21%) or the bare ZnO NRs (0.87%). In the case of low sulfur content, a shell layer of In(OH)xSy or/and In(OH)3 is formed as observed by the presence of –OH observed by FTIR analyses. The presence of higher amounts of hydroxide groups modifies the bandgap and work function of the InxSy shell and facilitates dye adsorption, increasing the final solar cell performance.

Titania (TiO2) nanoparticles have been synthesized using organic precursor technique. The titania nanoparticles were characterized. The results indicated that the prepared titanium oxalate and citrate precursors were transformed to anatase TiO2 phase at temperature 400 8C for 2 h. Dye-sensitized solar cells were assembled using the prepared nanocrystalline TiO2 with large surface area. The specific surface area SBET was 80.9 and 78.6 m2/g using oxalic and citric acids, respectively. The power efficiency was 3.5 and 2.4%. A brief discussion on the possible reasons behind the low power conversion efficiency observed for these type of solar cells was reported.
Lipoinjection with Adipose Stem Cells for Nasal Modeling: Rhino Cell, a Highly Versatile Alternative

It is undeniable that a significant number of patients who want to improve their facial appearance is increasingly interested in nonsurgical procedures. Without a doubt, the use of autologous fat could not be left out as a magnificent alternative for nasal modeling simply because of four influential factors: ease of collection, compatibility, the temporality of the results, and safety. This work describes an innovative alternative technique for nasal modeling using micrografts enriched with adipose-derived mesenchymal stem cells (ASCs). With this technique, fat was collected and divided into two samples, nanofat and microfat. Nanofat was used to isolate the ASCs; microfat was enriched with ASCs and used for nasal modeling. Lipoinjection was performed in a supraperiosteal plane on the nasal dorsum. Through a retrolabial access, the nasal tip and base of the columella were lipoinjected. We consider that nonsurgical nasal modeling using micrografts enriched with ASCs can be an attractive and innovative alternative. This technique will never be a substitute for surgical rhinoplasty. It can be performed in a minor procedure area with rapid recovery and return to the patient’s daily activities the next day. If necessary, the procedure can be repeated.

Objective To find the safety of long-acting injectable antipsychotics (LAIs) compared to each other, and/or placebo in the treatment of schizophrenia (SCZ) and/or schizoaffective disorder (SZA).Methods We performed a systematic review and a network meta-analysis of randomized controlled trials (RCTs) comparing the safety of LAIs versus other LAIs or placebo in adults diagnosed with SCZ or SZA. The primary outcomes were treatment emergent adverse events (TEAEs), serious treatment emergent adverse events (STEAEs), and deaths. The secondary outcomes included treatment discontinuations due to adverse events and all-cause discontinuations.Results Seventeen RCTs were included (n=7,908). There were no significant differences between LAIs and placebo in the risk of presenting TEAEs. LAIs had a significant lower risk of presenting STEAEs except for aripiprazole. No significant differences in deaths were found. LAIs showed a significant protective effect against all-cause discontinuation, except for haloperidol. Only aripiprazole had a significantly lower risk of treatment discontinuation due to adverse events.Conclusion We found no significant differences in the risk of presenting TEAEs between LAIs and placebo. The majority of LAIs had a significantly lower risk of presenting STEAEs than placebo. Development of international guidelines for the report of safety outcomes related to antipsychotics especially for LAIs in clinical trials could minimize report and interpretation biases and improve the accuracy of posterior meta-analysis.
