Published: October 2022

Keberhasilan budidaya secara intensif lele Sangkuriang (Clarias gariepinus var Sangkuriang) sangat tergantung dari keberadaan pakan. Dalam kegiatan budidaya pakan merupakan komponen yang membutuhkan biaya tinggi hampir 50-60% dari biaya produksi. Kondisi tersebut kemungkinan dikarenakan efisiensi pakan belum maksimal untuk mendukung pertumbuhan ikan. Salah satu solusi untuk mengatasi permasalahan tersebut dengan suplementasi Saccharomyces cerevisiae dalam pakan komersil. Tujuan penelitian ini untuk mengkaji pengaruh suplementasi S. cerevisiae pada pakan buatan komersial terhadap keceernaan protein, efisiensi pemanfaatan pakan dan pertumbuhan benih lele Sangkuriang. Perlakuan dalam penelitian ini adalah suplementasi S. cerevisiae pada pakan buatan komersial dengan dosis berbeda, yaitu 0 %/kg pakan (A), 0,5 %/kg pakan (B), 1 %/kg pakan (C), 1,5 %/kg pakan (D) dan 2 %/kg pakan (E). Suplementasi S. cerevisiae pada pakan buatan komersial berpengaruh nyata (P<0,05) terhadap keceernaan protein, efisiensi pemanfaatan pakan dan pertumbuhan, namun tidak berpengaruh nyata (P>0,05) terhadap kelulushidupan benih lele Sangkuriang. Dosis S. cerevisiae 2 %/kg pakan merupakan dosis terbaik bagi benih lele Sangkuriang menghasilkan nilai ADCp, EFU, dan RGR tertinggi sebesar 76,38%; 80,34% dan 4,03 g/hari.

Reproducibility and robustness of motor cortical stimulation to assess muscle relaxation kinetics
Authors: Molenaar Joery P. , van Zandvoort Elianne , van Engelen Baziel G. , Voermans Nicol C. , Doorduin Jonne
Published: October 2022

Transcranial magnetic stimulation (TMS) of the motor cortex can be used during a voluntary contraction to inhibit corticospinal drive to the muscle and consequently induce involuntary muscle relaxation. Our aim was to evaluate the reproducibility and the effect of varying experimental conditions (robustness) of TMS‐induced muscle relaxation. Relaxation of deep finger flexors was assessed in 10 healthy subjects (5 M, 5 F) using handgrip dynamometry with normalized peak relaxation rate as main outcome measure, that is, peak relaxation rate divided by (voluntary plus TMS‐evoked)force prior to relaxation. Both interday and interrater reliability of relaxation rate were high with intraclass correlation coefficient of 0.88 and 0.92 and coefficient of variation of 3.8 and 3.7%, respectively. Target forces of 37.5% of maximal voluntary force or higher resulted in similar relaxation rate. From 50% of maximal stimulator output and higher relaxation rate remained the same. Only the most lateral position (>2 cm from the vertex) rendered lower relaxation rate (mean ± SD: 11.1 ± 3.0 s−1, 95% CI: 9.0–13.3 s−1) compared to stimulation at the vertex (12.8 ± 1.89 s−1, 95% CI: 11.6–14.1 s−1). Within the range of baseline skin temperatures, an average change of 0.5 ± 0.2 s−1 in normalized peak relaxation rate was measured per 1°C change in skin temperature. In conclusion, interday and interrater reproducibility and reliability of TMS‐induced muscle relaxation of the finger flexors were high. Furthermore, this technique is robust with limited effect of target force, stimulation intensity, and coil position. Muscle relaxation is strongly affected by skin temperature; however, this effect is marginal within the normal skin temperature range. We deem this technique well suited for clinical and scientific assessment of muscle relaxation.
Semi peripheral scholars negotiating internationalizing institutional strategies with translingual tactics in academic discourse
Authors: Stoian Monica Elena
Published: October 2022

This article takes a closer look at the complexity of scholarly communication in the specific context of a German University by discussing the relevance of individual discourse tactics of European scholars with a heterogeneous background in communicating in English. The case study featured three scholars from the fields of Neurobiology and Microbiology. The data comes from interviews with the scholars, perusal of their drafts, and policy documents on the publishing expectations in their scientific community. Borrowing de Certeau’s terms strategies and tactics, I treat strategies as belonging to institutions, as manifested in tacit and explicit normative policies on publishing expectations and academic requirements in the name of internationalizing scholarship. Tactics are demonstrated by the dynamic and creative practices of scholars in the discourse practices they adopt to negotiate restrictive policies. While the policies are largely monolingual and monolithic, the practices of scholars draw from their translingual resources and social communicative ecologies. The article demonstrates through a case study that translingual practice can be a resource in negotiating dominant academic conventions for semi peripheral scholars.

A long delay and a poor data transfer rates have been observed in radio frequency (RF) communication and therefore inter-satellite communication has become more common in recent years and optical wireless communication has advanced dramatically. Owing to its multiple advantages, including large channel bandwidth, high-speed connectivity and economical operations, IsOWC technology is becoming popular among researchers. Uniphase modulations such as NRZ modulation does not have efficient spectrum for high speed inter-satellite communication. PDM-256-QAM at 160 Gbps over IsOWC channel is demonstrated in this work using matched filter and DSP. Proposed system is investigated for PDM-256-QAM at 850 and 1550 nm wavelength and results analyzed in terms of Q factor, log symbol error rate (SER) and error vector magnitude (EVM).

Objectives

Excessive adiposity is believed to contribute to insulin resistance, resulting in more complex metabolic outcomes and poorer glycaemic control. This study aimed to determine the prevalence of overweight/obese, excessive adiposity, and metabolic syndrome in type 1 diabetes mellitus (T1DM) children, who were from a relatively overweight/obese population, and to assess the effects on glycaemic control.

Methods

A cross-sectional study was conducted from November 2019 to August 2020 on T1DM children between 6 and 18 years old who attended the Paediatric Endocrine Clinic Putrajaya Hospital. Anthropometry and bioelectrical impedance analysis (Inbody 720) were measured to analyse their effects towards glycated haemoglobin (HbA1c) via SPSS 21.

Results

A total of 63 T1DM were recruited with an equal male-to-female ratio. The mean age was 12.4 ± 3.3 years old with a mean HbA1c of 9.8 ± 2.0%. The prevalence of overweight/obese and excessive body fat was 17.5 and 34.9%, respectively. Only 3 (6.8%) fulfilled the metabolic syndrome criteria. The waist circumference had a significant relationship with HbA1c. Every 10 cm increment of waist circumference was predicted to raise HbA1c by 0.8. The odds ratio of having abdominal obesity among T1DM with excessive body fat was 9.3 times.

Conclusions

Abdominal obesity is significantly associated with a poorer glycaemic control in T1DM children. Monitoring of waist circumference should be considered as part of the routine diabetic care.

Preterm infants face a significant risk of brain injury in the perinatal period, as well as potential long-term neurodevelopmental disabilities. However, preterm children with brain injury lack specific clinical manifestations in the early days. Therefore, timely and accurate diagnosis of brain injury is of vital importance. This study was to explore the diagnostic efficiency of myelin basic protein (MBP) and 8-oxo-deoxyguanosine (8-oxo-dG) serum levels in brain injury of premature infants. A total of 75 preterm infants with gestational age between 28 and 32 weeks and birth weight higher than 1,000 g were prospectively included. MBP serum levels were significantly higher in premature infants with white matter injury (WMI). 8-oxo-dG serum levels were significantly increased in both WMI and periventricular–intraventricular hemorrhages (PIVH). MBP and 8-oxo-dG were significantly correlated. The area under the curve was 0.811 [95% confidence interval (CI) 0.667–0.955;p= 0.002] in MBP and 0.729 (95% CI 0.562–0.897;p= 0.020) in 8-oxo-dG. Therefore, the results showed that high MBP levels indicated a possibility of WMI in the premature brain during the early postnatal period, while high 8-oxo-dG levels were closely related to both WMI and PIVH, thus suggesting that MBP and 8-oxo-dG could be used as potential neuro-markers of preterm brain injury.

Published: October 2022

We demonstrated silicon-on-insulator (SOI)-based high-efficiency metalenses at telecommunication wavelengths that are integrable with a standard 220 nm-thick silicon photonic chip. A negative electron-beam resist (ma-N) was placed on top of the Si nanodisk, providing vertical symmetry to realize high efficiency. A metasurface with a Si/ma-N disk array was numerically investigated to design a metalens that showed that a Si/ma-N metalens could focus the incident beam six times stronger than a Si metalens without ma-N. Metalenses with a thick ma-N layer have been experimentally demonstrated to focus the beam strongly at the focal point and have a long depth of field at telecommunication wavelengths. A short focal length of 10 μm with a wavelength-scale spot diameter of approximately 2.5 μm was realized at 1530 nm. This miniaturized high-efficiency metalens with a short focal length can provide a platform for ultrasensitive sensors on silicon photonic IC.

Iron metabolism: pathways and proteins in homeostasis
Authors: Arora Ekta Kundra , Sharma Vibha
Published: October 2022

Iron is essential to human survival. The biological role and trafficking of this trace essential inorganic element which is also a potential toxin is constantly being researched and unfolded. Vital for oxygen transport, DNA synthesis, electron transport, neurotransmitter biosynthesis and present in numerous other heme and non-heme enzymes the physiological roles are immense. Understanding the molecules and pathways that regulate this essential element at systemic and cellular levels are of importance in improving therapeutic strategies for iron related disorders. This review highlights the progress in understanding the metabolism and trafficking of iron along with the pathophysiology of iron related disorders.
“I had already tried that before going to the doctor” – exploring adolescents’ with knee pain perspectives on ‘wait and see’ as a management strategy in primary care; a study with brief semi-structured qualitative interviews

Published: October 2022

Objectives

The aim of this study was to examine how the “wait-and-see” recommendation affects adolescents’ understanding of their illness and symptoms and their care-seeking behavior.

Methods

This study included brief qualitative, semi-structured online interviews. Adolescents (age 10–19 years) with long-term knee pain, who had been recommended “wait-and-see” by their general practitioner (GP), were recruited via previous studies and social media. Two researchers conducted brief semi-structured interviews through Microsoft Teams. An interview guide with open questions was created prior to the interviews and updated as new questions emerged. The extracted data was transcribed and analyzed via a reflexive thematic approach in NVivo.

Results

Eight adolescents (mean age 17.8) with longstanding or recurrent knee pain (mean duration 3.5 years) were included. The analysis identified four main themes: (1) The perception of wait and see over time, (2) The GP’s acknowledgement and consideration, (3) experienced limitation from knee pain and (4) the importance of getting a diagnosis. The perception of “wait-and-see” approach changed from positive to negative when adolescents received the recommendation multiple times. Adolescents experienced frustration with their situation and a lack of consideration from their GP made them cautious about seeking additional care. Knee pain significantly limited the adolescents’ physical-and social activities. Receiving a diagnosis was important and helped adolescents dealing with their pain.

Conclusions

The connotation of wait-and-see changed from positive to negative for adolescents when receiving the recommendation multiple times. The participants felt getting a clinical diagnosis was a relief. Furthermore, the lack of consideration and acknowledgement from the GP plays an essential role in the adolescent’s understanding of their knee pain.

Implications

Recommending adolescents to “wait-and-see” multiple times in relation to their knee problems can lead adolescents experience frustration and a lack of consideration from their GP. It would be advisable for GPs to provide adolescents with a diagnosis as it can facilitate them in dealing with their pain and to use simple language when explaining adolescents their condition to improve communication.
CUANDO LA MEDICINA GRÁFICA ES PERIODISMO CÓMIC: HISTORIAS DE PANDEMIA EN VIÑETAS
Authors: Matos Agudo Diego
Published: October 2022

El cómic, entendido como “una yuxtaposición de palabras e imágenes, en una determinada secuencia, con el objetivo de comunicar historias e ideas”, ha dado el salto a la comunicación sanitaria en forma de lo que se conoce como Medicina Gráfica, que aúna el lenguaje de las viñetas, con el contenido de información para la salud, desde las patografías gráficas a las historias autobiográficas o divulgativas. Un concepto naciente que está en boga. Asimismo, de forma histórica, el Periodismo Cómic se ha considerado como un mero formato de reportaje, de crónica, o, según algunos estudios, como un subgénero del periodismo gráfico. Aunque está claro que este “periodismo lento”, que, en palabas de Joe Sacco, se centra en “la gente que está debajo de los titulares”, es ya un objeto diferente, innovador y único, que desborda el marco teórico-conceptual de los géneros periodísticos dejando a estas obras en un limbo complicado de catalogar. Grandes cabeceras como The New Yorker, Details, Time, New York Time Magazine, XXI, El País, El Norte de Castilla… han usado estas historietas de no ficción del mismo modo y al mismo nivel que plantean sus reportajes, sus fotografías, sus infografías… Este fenómeno global también se ha asentado, llegando a trasladarse en propuestas informativas o narrativas de primer orden, en medios de comunicación tradicionales, más allá de las obras más largas en forma de novela gráfica. Periodismo Cómic y Medicina Gráfica; dos conceptos novedosos que convergen en una fina línea, sobre todo cuando en el 2020, una pandemia global llegó para cambiarlo todo. De entonces a ahora, varias piezas en la frontera de los cómics periodísticos y la medicina gráfica han surgido en todo el mundo. En esta línea, en España destacan: Efectos Secundarios. 19 historietas del covid, de AA.VV.; Pandemia, de AA.VV, y Una historia del Confinamiento, de Paco Roca. En este texto se pretende profundizar en el uso del cómic periodístico en la medicina gráfica con el estudio de caso de las obras surgidas durante la pandemia de la COVID-19, dentro de estos parámetros informativo-divulgativos, como un nuevo formato, una nueva tendencia en comunicación y salud repleta de posibilidades. Un repaso; una hoja de ruta de este nuevo género periodístico que está en auge, con paso lento, pero firme y sus confluencias con el concepto de la graphic medicine.
