Published: October 2019

Abstract
Objective To evaluate the association between the upright and supine maternal positions for birth and the incidence of obstetric anal sphincter injuries (OASIs).
Methods Retrospective cohort study analyzed the data of 1,728 pregnant women who vaginally delivered live single cephalic newborns with a birth weight of 2,500 g. Multiple regression analyses were used to investigate the effect of the supine and upright positions on the incidence of OASIs after adjusting for risk factors and obstetric interventions.
Results In total, 239 (13.8%) births occurred in upright positions, and 1,489 (86.2%) in supine positions. Grade-III lacerations occurred in 43 (2.5%) patients, and grade-IV lacerations occurred in 3 (0.2%) women. Supine positions had a significant protective effect against severe lacerations, odds ratio [95% confidence interval]: 0,47 [0.22–0.99], adjusted for the use of forceps 4.80 [2.15–10.70], nulliparity 2.86 [1.44–5.69], and birth weight 3.30 [1.56–7.00]. Anesthesia (p < 0.070), oxytocin augmentation (p < 0.228), shoulder dystocia (p < 0.670), and episiotomy (p < 0.559) were not associated with the incidence of severe lacerations.
Conclusion Upright birth positions were not associated with a lower rate of perineal tears. The interpretation of the findings regarding these positions raised doubts about perineal protection that are still unanswered.

Published: October 2019

AbstractAlthough mature cystic teratoma (MCT) is benign, malignant transformation (MT) occurs in ∼ 1% to 2% of all cases, and usually consists of squamous cell carcinoma (SCC), which accounts for ∼ 80% of the cases. Spindle-cell (sarcomatoid) carcinoma (SCSC) is an uncommon type of SCC, comprising up to 3% of all cases. The lack of characteristic symptoms and specific imaging findings may lead to preoperative misdiagnosis. Moreover, the clinicopathologic characteristics, the treatment, the prognostic factors and the mechanism of MT have not yet been well understood due to the rarity of such tumors, especially in women of reproductive age. The authors present a case of a 34-year-old patient with 14 weeks of gestation who was diagnosed with an adnexal mass suggestive of ovarian teratoma. A laparoscopy salpingo-oophorectomy was performed after 6 months of delivery, and the histological exam revealed a sarcomatoid SCC in the MCT.

Published: October 2019

Abstract
Introduction Neurosurgical anatomy is traditionally taught via anatomic and operative atlases; however, these resources present the skull base using views that emphasize three-dimensional (3D) relationships rather than operative perspectives, and are frequently written above a typical resident's understanding. Our objective is to describe, step-by-step, a retrosigmoid approach dissection, in a way that is educationally valuable for trainees at numerous levels.
Methods Six sides of three formalin-fixed latex-injected specimens were dissected under microscopic magnification. A retrosigmoid was performed by each of three neurosurgery residents, under supervision by the senior authors (C.L.W.D. and M.J.L.) and a graduated skull base fellow, neurosurgeon, and neuroanatomist (M.P.C.). Dissections were supplemented with representative case applications.
Results The retrosigmoid craniotomy (aka lateral suboccipital approach) affords excellent access to cranial nerve (CN) IV to XII, with corresponding applicability to numerous posterior fossa operations. Key steps include positioning and skin incision, scalp and muscle flaps, burr hole and parasigmoid trough, craniotomy flap elevation, initial durotomy and deep cistern access, completion durotomy, and final exposure.
Conclusion The retrosigmoid craniotomy is a workhorse skull base exposure, particularly for lesions located predominantly in the cerebellopontine angle. Operatively oriented neuroanatomy dissections provide trainees with a critical foundation for learning this fundamental skull base technique. We outline a comprehensive approach for neurosurgery residents to develop their familiarity with the retrosigmoid craniotomy in the cadaver laboratory in a way that simultaneously informs rapid learning in the operating room, and an understanding of its potential for wide clinical application to skull base diseases.

Published: October 2019

Abstract
Objectives To describe a far lateral approach for microsurgical clipping of a ruptured posterior inferior cerebellar artery (PICA) aneurysm involving the hypoglossal nerve, with emphasis on the microsurgical anatomy, and technique.
Design A far lateral craniotomy is performed in the lateral decubitus position and the transverse and sigmoid sinuses were exposed. After opening the dura, sutures are placed to allow gentle mobilization of the sinuses. The ipsilateral cerebellar tonsil is mobilized and the PICA is followed to its junction with the vertebral artery. Hypoglossal nerve rootlets are draped over the dome of the aneurysm. Mobilization of the PICA and the hypoglossal nerve away from the lateral medulla allows microsurgical clipping of the aneurysm neck. Photographs of the region are borrowed from Dr Rhoton's laboratory to illustrate the microsurgical anatomy.
Participants The senior authors performed the surgery. The video was edited by Drs. V.N. and J.B. Chart review and literature review were performed by Drs. W.M. and J.B.
Outcome Measures Outcome was assessed with successful clip occlusion and postoperative neurological function.
Results There was complete clip occlusion of the PICA aneurysm with no postoperative neurological deficits. The patient was discharged home after an uneventful hospital course.
Conclusion The far lateral approach provides an adequate corridor to the ventrolateral brainstem for microsurgical treatment of PICA aneurysms. An adequate understanding of the relevant microsurgical anatomy is the key to safe and effective clipping in this region.The link to the video can be found at: https://youtu.be/yhjKRIG5H74.
Evaluation of the Mastoid Emissary Canals with Computerized Tomography in Patients with Chronic Otitis Media
Authors: Ozen Ozkan , Sahin Caner 
Published: October 2019

Abstract
Background The mastoid emissary veins (MEVs) pass through the mastoid emissary canal-mastoid foramen (MEC-MF) in the mastoid region of the skull. MEVs can give rise to complications during surgical procedures. The purpose of our study was to investigate the morphological and morphometric characteristics of MECs of patients with clinical chronic otitis media (COM) using high-resolution computed tomography (HRCT).
Methods Patients diagnosed with COM and undergoing temporal HRCT were identified by retrospectively scanning our hospital's automation system. Patients undergoing temporal HRCT for reasons other than COM, infection or tinnitus were identified for the control group by scanning the PACS archive. Sixty-two mastoid regions were examined in 38 unilateral and 12 bilateral COM patients, and 100 mastoid regions in the 50 patients in the control group. The presence of an accessory MEC-MF and MEC-MF diameters was evaluated in both groups.
Results Main MEC diameters on the side of the ear with COM were 1.6 mm, and total accessory and main MEC diameters were 1.8 mm, both values being significantly higher than in the control group. Presence of accessory MEC on the side of the ear with COM was determined at 61.8%, significantly higher than in the control group.
Conclusion Preoperative awareness of cranial venous drainage abnormalities is important to reduce surgical complications. Our study shows that MECs may be wider in diameter in patients with COM. MECs in COM patients must be identified before surgery to the mastoid region.

Published: October 2019

Abstract
We report on optimization of growth conditions of GaAs/GaNAs/GaAs core/shell/shell nanowire (NW) structures emitting at ∼1 μm, aiming to increase their light emitting efficiency. A slight change in growth temperature is found to critically affect optical quality of the active GaNAs shell and is shown to result from suppressed formation of non-radiative recombination (NRR) centers under the optimum growth temperature. By employing the optically detected magnetic resonance spectroscopy, we identify gallium vacancies and gallium interstitials as being among the dominant NRR defects. The radiative efficiency of the NWs can be further improved by post-growth annealing at 680 °C, which removes the gallium interstitials.

Abstract

Objective. In the core of a brain infarct, characterized by severely reduced blood supply, loss of neuronal function is rapidly followed by neuronal death. In peripheral areas of the infarct, the penumbra, damage is initially reversible, and neuronal activity is typically reduced due to ischemia-induced synaptic failure. There is limited understanding of factors governing neuronal recovery or the transition to irreversible damage. Neuronal activity has been shown to be crucial for survival. Consequently, hypoxia induced neuronal inactivity may contribute to cell death, and activation of penumbral neurons possibly improves survival. Adversely, activation increases ATP demand, and a balance should be found between the available energy and sufficient activity. Approach. We monitored activity and viability of neurons in an in vitro model of the penumbra, consisting of (rat) neuronal networks on micro electrode arrays (MEAs) under controlled hypoxic conditions. We tested effects of optogenetic and electrical activation during hypoxia. Main results. Mild stimulation yielded significantly better recovery of activity immediately after re-oxygenation, compared with no stimulation, and a 60%–70% higher survival rate after 5 d. Stronger stimulation was not associated with better recovery than no stimulation, suggesting that beneficial effects depend on a delicate balance between sufficient activity and available energy. Significance. We show that mild activation during hypoxia/ischemia is beneficial for cell survival in an in vitro model of the penumbra. This finding opposes the current common belief that suppression of neuronal activity is the cornerstone of neuroprotection during cerebral ischemia, and may open new possibilities for the treatment of secondary brain damage after stroke.

Published: October 2019

Abstract
Indonesia is one of countries with abundant amount of herbal plant species. These plants have potential to be used as an ingredient of alternative medication, which is known as Jamu. There have been already many previous research related to the topic of formulating jamu efficacy using network pharmacology that construct link among plants and disease. Moreover, some researchers were more interested in predicting the interaction between chemical compound and protein to formulate Jamu. Commonly, Jamu formula contains four basics of pharmacology activities including analgesic, anti-inflammatory, antibacterial, and target pharmacology activity. Ijah has not implemented these four essential characteristics yet for predicting jamu formula. This research implemented new molecular Jamu formulation composed by some active compounds from plant with analgesic, anti-inflammatory, antibacterial and target pharmacology activity characteristic. The result of this study showed a list of plants which consisted of herbal compounds that could be used to formulate jamu as an alternative to synthetic medicine.

Abstract
The United Nations strongly support the progress towards sustainable agriculture, food security, sustainable management of life on land in a simultaneous approach. Oil production, though on increasing demand, is causing severe loss of biodiversity in tropical areas, Indonesia being the country with the most environmental damage due to this crop. Geographical Information Systems (GIS) and Unmanned Aerial Vehicles (UAVs) for base-remote sensing are promising tools to help with environmental conservation in oil palm plantations and to improve production efficiency and quality of crops. While different UAVs exist in the market, multi-rotor UAVs have already been used for oil palm plantation monitoring. There are more than 100 different Vegetation Indices (VIs); the Normalized Difference Vegetation Index (NDVI) is often used in smart agriculture. Still, there is a huge need for algorithms that assess floristic diversity. To maintain some elements of the Indonesian biodiversity within oil palm plantations, experimentation with algorithms were carried out. The imagery shows great potential for future research.

Abstract
Chicken slaughterhouses generate a large volume of chicken feet as a waste or by product. Nowadays, the chicken feet have not been optimally utilised. One of the ways to increase added value of the chicken feet is to utilize collagen contained in it. The objectives of this study were to obtain the best treatments in pre-treatment and hydrolysis stages of collagen extraction from chicken feet using hydro-extraction method, and to characterise the physico-chemical properties of the isolated collagen. Collagen extraction consisted of three stages of pre-treatment, hydrolysis, and hydro-extraction. Pre-treatment stage used NaOH concentrations of 0.5, 1, and 2 M, and soaking times of 2, 4, 6, and 8 hours. The hydrolysis used CH3COOH concentrations of 0.1, 0.3, and 0.5 M, and soaking times of 1, 2, and 3 hours. The best condition of pre-treatment was 0.5 M NaOH concentration with 6 hours of soaking time, while the best condition of hydrolysis was 0.5 M CH3COOH concentration with 1 hour soaking time. FTIR spectroscopy showed that the isolated collagen amino acids consisted of amide A, amide B, amide I, amide II, and amide III groups. The dominant amino acid contents were glycine, L-serine, L-proline, L-glutamic acid, and L-alanine.

Abstract
Rice is a strategic product in Indonesia development because it becomes an essential aspect of economic growth. The inefficiency of food agribusiness system becomes a crucial aspect of developing the sustainable industry. Those affected by the lack of using technology that impacts the high amount of waste and losses, the inefficiency of time, etc. It could impact the competitiveness, equity of value-added, unstable price and poverty. Some amount of rice grade materials rejected from the production line due to the unsatisfactory quality. This article aimed to analyze efficiency in the food industry as a preparation in the development of agricultural digital supply chain. The analysis shows that inefficiency in the rice industry due to a lot of manual activities that impact the time and expense efficiency (labor intensive rather than the use of technologies). Improving efficiency in the food industry is not only about time and cost management, but it becomes complex issues which are involved in several barrier factors. It should be anticipated with appropriate technology, improving skills, and also develop an integrated logistics system. Importantly, improving efficiency in rice industry needs to develop soft skill as the key success factors to improve efficiency in the digital supply chain for the rice industry.

AbstractTo optimise land use, an overview regarding its topography of the proposed land is essential to be portrayed, especially to depict the slope, elevation, calculation of cut and fill, as well as planning for water supply. However, in practice, high-resolution topographic data are hard to obtain and are highly priced. As an alternative solution, commercial small drones could be utilized to improve the input for such data. Commercial small drones could be utilized as a photogrammetric approach to obtain detailed digital surface model (DSM). This study aimed to get high-resolution of topography condition using commercial small drones and evaluate the result comparing to terrestrial surveying. The approach was done using Drone DJI Phantom 3 Professional, where the ground control points (GCPs) were undertaken with GPSMAP 64s SEA. The study area was ±23 ha proposed for fodder cultivation, located at Ngantru Village, Bojonegoro, East Java Province in Indonesia. Outcomes obtained from the analysis were orthophoto, digital models, and contours. The results yielded an efficient approach for mapping compared to field/terrestrial surveying. The drone approach only cost IDR ±4,000,000, whereas terrestrial mapping (using electronic total station) was worth up to IDR ±25,000,000. As the expense altered significantly, the process of collecting data varied as well. The overall data acquisition using drone only took 2 hours to complete, while field survey may require up to 2 days of acquisition. Although results accuracies were also an issue, the output reliability for drone with errors from 0.5 to 6 m was somewhat acceptable. In conclusion, small commercial drones were one way to undertake efficient mapping (in terms of cost and time) compared to field/terrestrial survey.
A preliminary investigation of various signal phenomena generated by termite infestation
Authors: Nanda M A , Seminar K B , Nandika D , Maddu A 
Published: October 2019

Abstract
Subterranean termites are major urban pests in Indonesia and lead damage to wooden structures and buildings. Termite pest management involves two sections: prevention and control. The most crucial part of termite control is to detect termites; however, due to their cryptic behavior, the termite infestation evidence on wooden structures is difficult to detect visually. When termite infestation is active and wood damage is occurring, the distinction of various signal phenomena are released including moisture content, temperature and acoustic emission. The identification of these phenomena becomes the basic foundation for designing a future termite detection system. The aim of this study is to identify various signal phenomena generated by termite infestation. In this investigation, the pine wood, as the medium for termite infestation, was divided into two groups, i.e., the wood infested by 220 termites (‘infested’) and the normal wood as a control (‘uninfested’). Each signal phenomenon generated by termites was observed and analysed to produce six pieces of information, i.e., (a) moisture content; (b) temperature; (c) four information of acoustic emission such as energy, entropy, peak frequency and zero moment power. Based on statistical analysis of Duncan multiple range test (DMRT; two-way ANOVA, P ≤ 0.05), it was revealed that the information that can distinguish significantly between infested and uninfested wood are moisture content, temperature, energy, entropy and zero moment power. Finally, various phenomena (i.e., moisture content, temperature and acoustic emission) can be embedded and integrated in the sensing technology of termite detection.
