AbstractThe tumor microenvironment presents several therapeutic targets, with inflammation being one of them. In search of new drugs, plants have shown to be an effective source of potent anti-inflammatory and anticancer agents. This study aimed to evaluate the antitumoral and inflammatory activities of Boehmeria caudata aerial parts extract. Bioguided in vitro antiproliferative screening showed that phenanthroquinolizidine obtained from the aerial B. caudata ethanolic extract had a straight relationship with activity. Moreover, the orally administered ethanolic extract reduced Ehrlich solid tumor growth and displayed an anti-inflammatory effect in both evaluated experimental models (carrageenan-induced paw edema and croton oil-induced ear edema). These results suggest that the antitumor activity of the ethanolic extract could be explained by antiproliferative effects associated with anti-inflammatory action.
Osteotomies—When, Why, and How?
Authors: Locketz Garrett D. , Lozada Kirkland N. , Becker Daniel G. 
Published: March 2020

AbstractAn ideal nasal osteotomy should deliver precise, predictable, and reproducible cosmetic and functional results while minimizing soft-tissue trauma and postoperative complications. In addition to closing an open roof deformity after hump reduction, other common indications for osteotomies include the crooked nose and a wide bony vault. The literature has reported numerous and diverse osteotomy techniques as well as differences in timing of osteotomies. Each has its own merits and indications, and its proponents. In this article, we review the anatomy and nomenclature relating to osteotomies. We review the locations and paths of the osteotomies—lateral, intermediate, medial, and superior/transverse. We consider the percutaneous and endonasal approaches, as well as timing of osteotomies and other considerations. We also discuss technical considerations in the selection of instrumentation for osteotomies.
Nasal Obstruction after Mohs Surgery: Prevention and Correction
Authors: Rudy Shannon F. , Moyer Jeffrey S. 
Published: March 2020

AbstractAs rates of Mohs micrographic surgery (MMS) have risen over recent decades in the setting of increased incidence of nonmelanoma skin cancer, so too has the need for post-Mohs reconstruction. The nose is one of the most common sites of post-MMS nasal reconstruction and presents unique challenges that often require expertise in facial plastic and reconstructive surgery. In addition to the aesthetic importance of the nose, preserving nasal function and preventing nasal obstruction are paramount to successful nasal reconstruction. This article will provide a brief review of nasal anatomy, with a focus on particular anatomic risk factors for post-MMS reconstruction nasal obstruction, strategies to prevent nasal obstruction, as well as techniques to correct the problem when it arises.
Diaphyseal Screw Prominence in Distal Radius Volar Plating
Authors: Eng Kevin , Gil Stephen , Page Richard 
Published: March 2020

Abstract
Background Volar plating for distal radius fractures has become common. Screw prominence on the dorsal side from long screws can lead to tendon injury. Methods for detecting screws that penetrate the far cortex involve X-ray or ultrasound. These have focused on the distal row of screws. No studies have addressed screw penetration in the diaphysis. We describe two cases where diaphyseal screws caused symptoms. We then insert screws in the diaphysis of synbones 2 mm longer than measured and determine what angle of pronation or supination was best to detect this on X-ray.
Methods Three synbones were plated using Synthes volar plate. The three diaphyseal screws were drilled perpendicular to the plate, and the depth measured. Cortical 2.4-mm screws were inserted, 2 mm longer than measured. The three synbones were then placed in a custom clamp to measure rotation. Lateral X-rays were taken at 0 degree rotation, and 5, 10, and 15 degrees of supination and pronation. The prominence of each screw was measured using the synapse digital ruler.
Results For the screws that were placed at a neutral angle (perpendicular to the plate) the maximum visualization of the prominent tips occurred around 0 degree rotation. With screws angled 15 degrees ulna, maximum visualization was between 5 and 10 degrees of pronation. With screws angled 15 degrees radial, maximum visualization was between 5 and 10 degrees of supination. Every 5 degrees of rotation changes the profile of the screw by 0.4 mm.
Discussion The diaphysis of the radius becomes approximately trapezoidal distally. Prominent screws that are placed below the “peak” of the trapezoid may appear to be the correct length. Rotating the wrist into pronation or supination to bring the relevant cortex as parallel to the X-ray beam as possible will help to identify if screws are of the correct length. Screws that are prominent in the second compartment may be particularly symptomatic as the tendons here are closely opposed to the bone. We recommend screening for 2 mm diaphyseal screw prominence in neutral, with 10 degrees of pronation and supination.
Evaluation of Flexor Pollicis Longus Tendon Rupture after Treatment of Distal Radius Fracture with the Volar Plate

Published: March 2020

Abstract
Background The aim of this study is to evaluate the frequency of flexor pollicis longus (FPL) tendon rupture and factors leading to this rupture during the follow-up of patients who underwent volar plate fixation because of distal radius fracture.
Patients and Methods A total of 109 distal radius fractures of 102 patients treated with volar plate fixation and periodically followed up for at least 1 year between January 2013 and May 2018 were evaluated. Fractures were categorized according to the AO Foundation/Orthopaedic Trauma Association (AO/OTA) Fracture-Dislocation Classification and Soong's grading was used for classifying volar plate position. All patients operated were inquired retrospectively in terms of flexor tendon rupture.
Results Gender distribution revealed 45 females and 57 males. Mean age was 47.9 (range: 17–88) years. Mean period of follow-up was 27 months. Distribution of fractures in accordance with the AO/OTA distal radius classification was 6, 8, 7, 12, 24, 33, 11, and 8 patients with types A2, A3, B1, B2, B3, C1, C2, and C3, respectively. When volar plate positions were analyzed with Soong's classification, it revealed that 79 (72.4%), 23 (21.1%), and 7 (6.5%) plates were grade 0, 1, and 2, respectively. In total, evaluating the three patients with FPL rupture, it revealed that the volar plate was positioned distally during fixation because the fracture line had advanced to the distal of the watershed line, the distal portion of the plate had lost complete connection with the bone, and at this portion, it was observed that the pronator quadratus muscle was not covering the plate entirely (Soong's classification grade 2). Patients did not have additional flexor tendon injury.
Conclusion FPL tendon rupture is a rare but serious complication of volar plate fixation performed for distal radius fractures. We believe that appropriate choice of implant and careful surgical technique, along with the close follow-up of patients, with Soong's classification grade-2 volar positions would help in preventing this complication.
Level of Evidence This is a Level 3a, differential diagnosis/symptom prevalence study.
Clinical Tips of Cesarean Section in Case of Breech, Transverse Presentation, and Incarcerated Uterus
Authors: Takeda Jun , Ishikawa Gen , Takeda Satoru 
Published: March 2020

AbstractCesarean section in breech or transverse presentation involves more complicated procedures than cesarean section in cephalic presentation because the former requires additional manipulations for guiding the presenting part of the fetus, liberation of the arms, and the after-coming head delivery; therefore, those cesarean sections are likely to be more invasive. Making a rather wide uterine incision to prevent uterine injury during delivery of the fetus facilitates smooth delivery of the fetus. Furthermore, in cases of breech or transverse presentation, it is important to initially identify the presenting part of the fetus and guide it to the incision opening in the lower uterine segment, because delivering the presenting part of the fetus first is a basic rule of delivery of the fetus. Smooth delivery of the fetus by means of breech extraction can prevent excessive stress or injury to the fetus. Therefore, it is important to acquire the knowledge and skills necessary to perform these techniques, including the internal version. Smooth delivery of the fetus is also less invasive for the mother because an extension of the uterine excision or injury to arteries and veins in the uterus and parametrium can be avoided. Incarcerated uterus occurring in cases of pregnancy with intrapelvic adhesion, endometriosis, cervical myoma, or extended cervix may result in excessive uterine and cervical injury when a transverse incision of the lower uterine segment is performed without caution. These conditions may result in difficulty in fetal delivery. Therefore, it is important to identify risks in advance and to choose the incision line with great care. Countermeasures for difficult delivery of the fetus need to be mastered by all practitioners of obstetrics. If the transverse incision fails to reach the uterine cavity, an inverted T-shaped or J-shaped incision should be made. Risks of complications such as injury to the cervical canal, the vagina, the bladder or ureter, and massive hemorrhage must be kept in mind.

We obtain the iso-energy invariants of rough and fine Liouville equivalence, and conduct a comparative analysis of other systems known in rigid body mechanics. To obtain the results we apply the method of separation of variables and construct a new method, which is equivalent to the bifurcation diagram but does not require it to be constructed.

Iron sequestration by transferrin 1 mediates nutritional immunity inDrosophila melanogaster
Authors: Iatsenko Igor , Marra Alice , Boquete Jean-Philippe , Peña Jasquelin , Lemaitre Bruno 
Published: March 2020

SignificanceHosts sequester iron as a strategy to limit pathogen acquisition of this essential nutrient in a process termed nutritional immunity. Due to their in vitro antimicrobial activity, iron-binding proteins transferrins are suspected to play a role in iron sequestration. However, little is known about the in vivo role of transferrins. Here, we found thatDrosophila melanogasterexhibits infection-induced hypoferremia mediated by Transferrin 1. Due to excessive iron in hemolymph,Transferrin 1(Tsf1)-deficient flies are hypersusceptible to certain infections. Our study reveals that nutritional immunity is an important, previously unrecognized arm of immune defense inDrosophila. Using fly and bacterial genetics, we show that Tsf1 mediates nutritional immunity by sequestering iron from the pathogens in vivo on the whole-organism level.
Intervocalic voicing of Hungarian /h/
Authors: Deme Andrea , Bartók Márton , Gráczi Tekla Etelka , Csapó Tamás Gábor , Markó Alexandra 
Published: March 2020

Abstract
In this study, we investigated whether the amount of voicing, and the sound quality (expressed in HNR) of /h/ in syllable onset
are affected by intervocalic context (vs. post-pausal context), by backness and openness of the flanking vowels, and by a
phonological conditioner, pitch-accent. We showed that both measures were similarly high in all intervocalic positions
(irrespective of the presence of word-boundary and pitch-accent), while after a pause they were substantially lower, meaning
that /h/ was voiced, and more modally voiced intervocalically, than after a pause. Further, interaction of this effect with
that of vowel features led us to conclude that open, close, back, and front vowel groups should be considered internally
heterogeneous with respect to their effect on /h/ voicing.
Testing variability effects in Hungarian vowel harmony

Published: March 2020

Abstract
Hungarian backness harmony shows various degrees of transparency and variation, but the empirical testing of these variability
effects in corpora is problematic because of data sparseness. We have created an experiment using harmonically mixed stems and
four different harmonic suffixes, and collected information about the variants from native speakers in the form of a sentence
completion task. We show that there are significant differences between stem types, and that the harmonic suffix can also
affect the behaviour of the stem. Our results confirm that native speakers can learn unnatural patterns and that they obey the
Law of Frequency Matching (Hayes et al. 2009).
With or without the definite article
Authors: Rákosi György 
Published: March 2020

Abstract
That noun phrases may constitute a binding domain is a key component among the parallelisms between the syntax of noun phrases
and clauses. Reuland (2007, 2011) and
Despić (2011, 2015) have shown
recently that the definite article plays a crucial role in delimiting this domain, since dedicated possessive reflexive
anaphors are only possible in languages that lack a prenominal definite article. Hungarian has several anaphoric possessor
strategies, which vary in whether they require, allow, or prohibit the use of the definite article in the possessive noun
phrase. This paper gives an overview of the grammar of these strategies, and presents a discussion of the results of a
questionnaire survey that was conducted to better understand the delicate distribution of the definite article in these
constructions. The importance of these Hungarian data lies in showing that Reuland’s conjecture describes an important factor
not only in cross-linguistic, but also in language internal variation in definite article use in possessive DP’s.
Differing attitudes toward Spanish sign languages in three Galician pre- and primary schools
Authors: Bao Fente Maria C. , Báez Montero Inmaculada C. , Vázquez-Veiga Nancy 
Published: March 2020

Abstract
Research into multilingual communities in Europe shows parallels between spoken languages and sign
languages in relation to the influence of school and family on the origin and transformation of linguistic attitudes.
Compared with the number and variety of studies on spoken languages, however, relatively little research has been
carried out on the question of linguistic attitudes to sign languages. The dearth of specific research is further
compounded by the methodological challenge of how to apply indirect research techniques to the study of visual-spatial
languages. The results obtained in this study confirm the influence of linguistic attitudes on the teaching of deaf
pupils, as well as the need to resource and promote the development of plurilingual curricula in different language
modalities.

Published: March 2020

Abstract
The development of robots began when the military needed it as war equipment, and then it was used by some industries to develop production until now widely used for education and agriculture. Educational robots are usually more universal and simpler than industrial or military robots because robots for education are made only for simulations or prototypes. In this study, the authors surveyed prototypes of Educational botany robots, namely robots used to distinguish fruit maturity. In this journal, the behaviour-based control (BBC) algorithm will continue implemented into mobile robots. The movement of the mobile robot prepared in advance, and then actually the mobile robot is wheeled compared to the desired path. Besides, both kinematic and dynamic smelling mobile robots are derived and considered. In this study, only focused on mobile robots three-wheel differential drive, which will explore in a circular and straight path. In this journal, it can be found that image processing techniques can be used to determine the maturity of watermelons which are shown in different average values in each image obtained by the camera. The best models are generated by layer 32 hidden with an accuracy value of 87% at the training dataset level 60:10:30. The Behaviour Based Control Method has directional movements. But there was an error in each test so that I couldn’t take the watermelon correctly. The error rate reaches 25% from 40 tests or about ten failures in the form of deviating from the object point.

AbstractIn order to face the industry 4.0, Indonesia uses the so called K-13 curriculum which prioritizes in student’s character building based on local wisdom. Therefore, teachers have responsibility to continuously improve the teaching-learning method along with the rapid technological development. Up to recently, there are many teaching-learning approaches has been introduced such as science, environment, technology, and society (SETS). One teaching-learning approach emphasizes in the connection between the real event in our everyday life with science, environment, technology, and social life. Phosphor-based (Light Emitting Diode) LED is one of the current increasing attention topics in the lighting technologies, which plays a very important role as general lighting source. Therefore, it is important to introduce this technology from the earliest stage of education. This paper will describe the teaching-learning method of the current technology, phosphor-based LED, using SETS approach in K-13 curriculum.

AbstractMost nations in the globe have recognized English as an international language. Consequently, English must be used in internationally both spoken and written communication. The people who live in the country which English to be the foreign language or even the second language has to learn it. In order, they can communicate with all people in the world globally. The teaching English as a foreign language in Indonesia has the objective to improve students’ capacity in acquiring the language itself. Among four language skills; reading one of the skill to be learned because by understanding the text, it can help the students to comprehend the knowledge of science and technology. Reading is also the “gate” to acquire science and technology. Through reading the text, the students will gain a lot of knowledge related to their field. Regarding the importance of the students in comprehension of the text, then, the objective of this paper is to give the contribution idea to improve the students reading comprehension skills for university students by using multiple media and creating the effective teaching-learning process in the higher education institutions. The final results of this study showed that the implementation of multiple media improve the students’ ability in comprehending the English text because the student feel enjoys the teaching and learning of reading. It is hoped that the use of various creative multiple media will use not only in reading classroom but also in other subjects of English learning.
