GROWTH PERFORMANCE OF TILAPIA (Oreochromis niloticus) SEEDS THROUGH THE ADDITION OF PAPAIN ENZYME
Authors: Hodifa Veronitta , Mukti Retno Cahya
Published: July 2023

As a maritime country, Indonesia relies heavily on the aquaculture sector, including freshwater aquaculture. Freshwater aquaculture has been widely practised in the aquaculture of nila tilapia fish (Oreochromis niloticus). The obstacle that often arises in nila tilapia fish culture is the low growth of fish. Factors that cause low fish growth are the low ability of fish to digest the feed given. The papain enzyme can be used as a protein catalyst in feed, increasing growth rates and reducing production costs. This study was conducted from November to December 2022 at the Seberang Ulu 1 District, Palembang, South Sumatra. This study used an experimental method with treatment P0 being the control (without adding the papain enzyme) and P1 being the treatment with adding the papain enzyme at a dose of 2.25%. The P1 treatment produced the highest results: the absolute length growth of 3.49 cm, the absolute weight of tilapia of 9.8 g, feed efficiency of 98.30% and survival of 88.80%.

The proposed system uses Natural Language Processing (NLP) and Deep Learning (DL) techniques to extract voice data and translate it to text during medical consultations. Iterative model was adopted in the design of the system and the user interfaces was implemented by using NLP techniques, especially speech recognition and natural language understanding. Deep learning algorithm shows a great ability to build clinical decision support systems by extracting various information for medical diagnosis and produce result is few seconds. The result form the system testing shows that the installation size of the Progressive Web App (104 KB) is 42 times smaller than the native Android app (4.37 MB). In terms of render-speeds, the PWA rendered different results. The native app will launch the Android activity after 1408 ms after app icon tap (launch), while the progressive web app launches the application in 230 ms. The advent of cross-platform application development frame-works have made it much easier to create applications for multiple platforms for mobile devices. In spite of reduced learning effort, usually lower costs, and a faster time-to-market cross-platform methods always do not prevail in most cases. Although there are normal exclusions – like graphic-intensive games, which should to be programmed with the native software development kits (SDKS), choice between native apps, cross-platform generated ones, and Web apps can remain delicate. Whereas many diverse efforts have been made with respect to how cross-platform development frameworks ought to work, no technology is deemed unequivocally superior than the others. But a cross-platform mobile app has got an edge over native app development. It also recommends that developers adopt this technology of mobile app development due to its huge gains.

Published: July 2023

As an alternative assessment tool, peer assessment plays a crucial role in the teaching/ learning context. However, researches have observed that the students have different perspectives towards receiving peer feedback. Hence, the aim of this study was to investigate the students’ attitudes towards receiving peer feedback. Though, peer assessment is a popular and widely used in different fields of education, peer assessment is still a new concept in the context where this study has been carried out. The sample of this study consisted of 45 science students who were studying technology in a higher educational institute. The students received peer feedback for the oral presentations they made. A five-point Likert scale questionnaire comprising 15 statements was used as the research instruments of this study. The overall findings illustrated that the informants had positive attitudes towards the peer assessment process as 88.6% shared the opinion that peer assessment had helped them to improve their presentation skills. Also, 60% of the sample shared the opinion that the scores given by peers were fair and reasonable and it was significant to find out that 60% of the participants shared the opinion that they were not nervous about the peer assessment process irrespective of the fact that they were exposed to peer assessment for the first time. However, 55.8% of the sample shared the opinion that they preferred to receive grade from the teacher than from the peer. It is expected that the findings of the study will contribute to the teaching and learning context of Sri Lanka.

Published: July 2023

Load frequency control (LFC) is a critical factor in the design of an electrical power system. To obtain and sustain a steady state operation of a power system for the delivery of quality power, generated power must at all times equal the load demand plus the losses. To achieve this state a Load frequency control system also known as Automatic Generation Control system is employed in an interconnected power system. The load-frequency control (LFC) is used to maintain the balance between load and generation in each control area as well as maintain the tie-line power flow in a multi area interconnected power system (MAIPS). The main goal of LFC is to minimize the transient deviations and steady state error to zero in advance. In this paper, a literature review of some non-classical LFC schemes employed by researchers for multi area interconnected power system (MAIPS), using different techniques is presented, some advantage sand drawbacks of the reviewed schemes highlighted, comparison of schemes stated.

Published: July 2023

This research reveals the accurate strategy of zakat management carried out by 'Umar b. 'Abd al-Az?z through the political distribution model. Before Umar served as caliph, the pattern of zakat management was chaotic, the distribution was carried out without looking at efficiency, so that the distribution of zakat was not able to alleviate poverty, through political distribution policies it was able to elevate the economic status of the poor who were previously exposed to poverty. The significance of this research is to answer how the management of the distribution of zakat funds is very effective and locally integrated so that it is feasible to apply in the era of the Covid-19 pandemic. This research is a literature study with a descriptive qualitative approach. Data mining uses a single but in-depth method by examining the main documentation sources. The data obtained at the final stage were analyzed using the content analysis method. The resulting findings are 1) 'Umar b. 'Abd al-'Az?z applies political distribution in the distribution of zakat with the principle of priority, that is, zakat funds collected are prioritized for muzakki areas without being issued to other areas. 2) the regional welfare system is a top priority. Zakat management which consists of collection, utilization and distribution, is carried out in a separate locus area. This kind of management is appropriate for modern era zakat institutions and muzakki considering that Muslims are found in every area who have been financially affected by the Covid-19 pandemic.

Objectives: The aim of the current study was to assess the effect of hemoperfusion in COVID-19 patients with respiratory failure. Patients and Methods: In this prospective study, a total of 98 patients over the age of 18 with the positive COVID-19 polymerase chain reaction (PCR) test were investigated. The patients were divided into two groups; a control group consisting of 47 patients who did not receive hemoperfusion, and an exposed group consisting of 51 patients who met the criteria for hemoperfusion. Various parameters including complete blood cell counts, serum bilirubin, creatinine, C-reactive protein (CRP), and interleukin 6 (IL-6) levels were evaluated in all patients. Results: The results of our study revealed a statistically significant difference in intensive care unit (ICU) admission between the two groups. Hospitalization time (19.941±1.75 versus 14.615±1.39, P=0.021) and ICU time (14.98±1.30 versus 9.62±1.15; P=0.003) were significantly higher in patients who received hemoperfusion. Regarding the mortality rate, only 36.7% of the patients survived; however, there was no significant difference observed between the two groups (P=0.34). Conclusion: In conclusion, the findings of our study indicate that hemoperfusion in COVID-19 patients with respiratory failure led to a significant increase in hospital stay and ICU stay compared to those without hemoperfusion. Further research is needed to determine the optimal timing and frequency of hemoperfusion to improve treatment outcomes in COVID-19 patients with respiratory failure.

Parathyroid hormone (PTH) is a hormone produced by the parathyroid glands that regulates calcium and phosphate metabolism in the body. Magnesium is an essential mineral that plays a role in many cellular processes, including nerve and muscle function, DNA synthesis, and bone health. This review aims to examine the association between PTH and magnesium in health and disease states. Several studies have shown that lower levels of magnesium in the blood are associated with higher levels of PTH. This association has been observed in both healthy individuals and those with chronic kidney disease, primary hyperparathyroidism, and vitamin D deficiency. The mechanism by which magnesium regulates PTH synthesis is not yet fully understood but appears to involve magnesium’s role in the calcium-sensing receptor (CaSR) and cellular signaling pathways. In conclusion, the evidence suggests a clear and significant association between PTH and magnesium, with lower serum magnesium levels associated with elevated PTH levels. Further research is needed to understand clinical practice’s underlying mechanisms and implications.

There is increasing evidence that vitamin D deficiency may contribute to hypertension. Low vitamin D levels are associated with an increased risk of high blood pressure, and studies have shown that vitamin D supplementation can help lower blood pressure. However, more research is needed to fully understand the mechanisms by which vitamin D regulates blood pressure and to determine the optimal dosage for supplementation. Nevertheless, ensuring adequate vitamin D levels through diet or supplements may be essential for preventing and managing hypertension.

Osteoporosis is a chronic condition characterized by low bone density and deterioration of bone tissue. Several factors such as age, gender, genetics, and lifestyle choices can contribute to the development of osteoporosis.
Impact of parathyroid hormone on osteoporosis; a short look at the current knowledge
Authors: Zahmatkesh Mehrdad
Published: July 2023

Osteoporosis is a disease characterized by losing bone tissue, resulting in increased bone fragility and an increased risk of fractures. Parathyroid hormone (PTH) plays an essential role in the development of osteoporosis. High levels of PTH for prolonged periods lead to a decrease in bone density. However, intermittent administration of PTH is an effective treatment for osteoporosis, suggesting that careful dosing of PTH can have a therapeutic benefit in the treatment of osteoporosis.
Hyperparathyroidism and vessel diseases

Published: July 2023

Hyperparathyroidism is a condition where the parathyroid glands produce excess parathyroid hormone, increasing calcium levels in the blood. Chronic hypercalcemia due to hyperparathyroidism has been linked with an increased risk of cardiovascular disease and other vascular complications such as hypertension, atherosclerosis, and thrombosis.

Hyperparathyroidism causes high levels of PTH, which can lead to a variety of cardiovascular problems that can pose a significant risk to an individual’s overall health. In more severe cases, such as high blood calcium levels due to primary hyperparathyroidism, the individual may also experience increased risks of kidney stones, bone fractures, and osteoporosis.
Lithium-induced parathyroid disease; an updated mini-review
Authors: Mahmoodnia Leila
Published: July 2023

Lithium is a medication commonly used to treat bipolar disorder and other psychiatric conditions. However, long-term use of lithium can lead to parathyroid dysfunction, known as lithium-induced parathyroid disease. The exact mechanism underlying lithium-induced parathyroid disease is not fully understood. Still, it is believed that lithium interferes with the normal function of the parathyroid gland by inhibiting the synthesis and secretion of parathyroid hormone (PTH) and impairing the sensitivity of the parathyroid gland to calcium. The management of lithium-induced parathyroid disease depends on the type and severity of parathyroid dysfunction. In patients with hypoparathyroidism, treatment involves the replacement of calcium and vitamin D supplements. In severe cases, intravenous calcium may be necessary. In patients with hyperparathyroidism, treatment consists in discontinuing lithium therapy and monitoring serum calcium and PTH levels. In situations where hyperparathyroidism persists, or complications like kidney stones or osteoporosis arise, surgery may become necessary.

Introduction: Kidney diseases affect millions of people worldwide. Over several decades, electron microscopy has been an integral part of the kidney biopsy study repertoire. Objectives: In this study, we assessed the role of electron microscopy in the diagnosis of kidney diseases. Patients and Methods: This was a retrospective cross-sectional study conducted at a referral center over a 16-year period (2001-2016). The electron microscopy (EM), light microscopy (LM), and immunofluorescence (IF) profiles of the patients were assessed. The final diagnosis was based on EM, and the primary LM results were compared to those of EM in order to assess the contribution rate of EM to the final diagnosis. The role of EM was categorized as essential, helpful, or non-contributory. Results: A total of 2006 kidney biopsies were performed. Male subjects accounted for 44.3%, and adults for 74.1% of the cases. The most common diagnosis was lupus nephritis (LN) (20.7%), followed by focal segmental glomerulosclerosis (FSGS) (15.7%) and membranous glomerulonephritis (MGN) (14.5%). EM was the most contributory in hereditary nephritis and minimal change disease (MCD). Overall, EM was essential in 25.2%, helpful in 17.4%, and non-contributory in 57.4% of all 2006 cases. Conclusion: The common kidney disorders in this geographic area of Iran are LN, FSGS, and MGN. In about half of the patients, EM study played an important role in the more accurate diagnosis of kidney diseases and prevented misdiagnosis. This role has been found to be more prominent in inherited diseases. We recommend EM as a useful and indispensable tool for routine pathologic study of biopsies when possible.

Introduction: Fabry disease (FD) is a rare disease in which cardiovascular events are one of its manifestations. Aortic and mitral valve involvement are among its manifestations, but due to the concern of suture failure without enzyme replacement therapy (ERT), the desire for its surgery has been very low, and its reported cases have been few. After the introduction of ERT, cardiovascular surgery for such patients has been gradually reported from different places, but due to the high cost of ERT, it is not practically available to patients in the third world and the backward countries. Reports of the experiences of patients with FD who underwent cardiac surgery without ERT can help improve cardiac surgery in these patients. Case Report: A 34-year-old man diagnosed with FD due to chronic renal failure and underwent dialysis 3 times a week for 1.5 years became a candidate for kidney transplant. In pre-transplant examinations, dilatation of aortic root and aortic valve insufficiency were diagnosed, and the patient’s kidney transplant surgery was postponed until after cardiac surgery. The patient underwent cardiac surgery, aortic valve replacement, and ascending aortic replacement, as well as re-implantation of both right and left coronary buttons on the ascending aorta (Bentall procedure). The post-surgery period passed without any special event. The patient’s dialysis continued; after 4 months, he underwent kidney transplant surgery, and the one-year follow-up period also was good. Conclusion: Although there is very little evidence of cardiovascular surgery in patients with FD without ERT, and surgeons have always been worried about suture failure and complications of cardiac surgery, due to the high cost of ERT, this treatment is not available to everyone. The introduced patient underwent cardiac surgery by Bentall procedure without receiving ERT and was discharged without any special complications. By reporting and collecting similar cases, guidance may be provided for patients with FD for whom ERT is not available.
