Studi ini secara khusus mencoba untuk memaparkan proses penanganan tiang listrik amblas. Diketahui bahwa tiang listrik merupakan salah satu komponen penting dalam proses transmisi listrik dari gardu-gardu PLN ke masyarakat sebagai konsumen. Namun untuk beberapa daerah dengan kondisi tanah yang tidak mendukung, kelurahan Ratu Sima – Dumai Barat misalnya dengan komposisi tanah didominasi oleh gambut (dan/atau rawa gambut) yang memiliki karakteristik mudah amblas dan kemampuan menahan tekanan yang rendah menyebabkan beberapa tiang listrik yang dipasang di daerah ini mudah amblas. Berdasarkan hasil survei lapangan dan pemetaan per bulan April 2019 menunjukkan 11 tiang listrik amblas di daerah studi kasus. Kondisi ini bila tidak segera ditangani akan menyebabkan proses transmisi listrik tidak berjalan dengan baik atau bahkan terhenti. Oleh karena itu perlu dilakukan perbaikan atau penambahan komponen pada tiang listrik yang telah terpasang agar tidak semakin amblas atau bahkan tumbang. Berdasarkan hasil penelitian diketahui bahwa proses penanganan tiang listrik yang amblas dapat dilakkan dengan pemasangan manshet khusus pada tiang listrik. Ketebalan manshet kuhususyang dipasang pada tiang listrik yang amblas berbeda-beda tergantung dari kondisi tiang listrik saat dipasangi manshet dan kondisi tanah tempat tiang listrik berdiri.

Abstract
Short-term or acute temperature stress affect the immune responses and alters the gut microbiota of broilers, but the influences of long-term temperature stress on stress biomarkers and the intestinal microbiota remains largely unknown. Therefore, we examined the effect of three long-term ambient temperatures (high (HC), medium (MC), and low (LC) temperature groups) on the gene expression of broilers’ heat shock proteins (Hsps) and inflammation – related genes, as well as the caecal microbial composition. The results revealed that Hsp70 and Hsp90 levels in HC group significantly increased, and levels of Hsp70, Hsp90, IL-6, TNF-α, and NFKB1 in LC group were significantly higher than in MC group (p < 0.05). In comparison with the MC group, the proportion of Firmicutes increased in HC and LC groups, while that of Bacteroidetes decreased in LC group at phylum level (p < 0.05). At genus level, the proportion of Escherichia/Shigella, Phascolarctobacterium, Parabacteroides,and Enterococcus increased in HC group; the fraction of Faecalibacterium was higher in LC group; and the percentage of Barnesiella and Alistipes decreased in both HC and LC groups (p < 0.05). Functional analysis based on communities’ phylogenetic investigation revealed that the pathways involved in environmental information processing and metabolism were enriched in the HC group. Those involved in cellular processes and signaling, metabolism, and gene regulation were enriched in LC group. Hence, we conclude that the long-term temperature stress can greatly alter the intestinal microbial communities in broilers and may further affect the host’s immunity and health.

Published: March 2021

Objective: Non-thyroidal illness syndrome (NTIS) is associated with outcomes in Intensive Care Unit(ICU) patients. The objectives of the study were to assess the prognostic value of complete thyroid profile in critically ill patients and to determine the effect of thyroid hormone level in predicting mortality when used along with acute physiology and chronic health evaluation (APACHE) II score.Methods: The observational study was conducted at a tertiary care centre in Kolhapur, India. Critically ill adult patients admitted to intensive care units with APACHE II >10 was included(n=50). Relevant clinical investigations along with thyroid profile evaluation was carried out and APACHE II was calculated. Baseline characteristics of patients were compared. Performance of variables in predicting mortality was analysed. Correlation of APACHE II score with thyroid was also assessed in R software v-3.6.1.Results: The survival rate at ICU discharge was 54%. Mean T3, FT3, and T4 levels were significantly low in non-survivors(p=0.006758, p=0.0245 and p=0.00070 respectively). Mean APACHE II score was significantly high in non- survivor(p=2.94E-06). APACHE II score was significantly associated with the severity of disease (p=0.0235). APACHE II scores and FT3 were better predictors of mortality compared to other thyroid hormones (AUC =0.8519±0.0535). FT3 showed high correlation with APACHE II score(r=-0.4083; p=0.0032). Inclusion of thyroid hormone levels with APACHE II scores improved the prediction of mortality in critically ill patients by 5.63%.Conclusion: Among thyroid hormones, FT3 is a better predictor of mortality. Use of thyroid hormone levels in conjunction with APACHE II scores improves the prognostication.

Background: Laparoscopic cholecystectomy has emerged as a popular alternative to traditional open cholecystectomy in the management of cholelithiasis. It has several advantages .Pneumoperitoneum and trendelenburg positioning causes release of stress hormones and ultimately changes in hemodynamic parameters. Stretching of peritoneum, abdominal wall associated with postoperative pain. So maintenance of haemodynamic stability, immediate postoperative pain control continues to be a major challenge for the anaesthesiologists.
Methods: Sample was selected by non-probability sampling technique in two groups distributed as- Group-L (Laparoscopic cholecystectomy, n=30) and Group-O (opencholecystectomy, n=30). Detailed history taking, physical examination and routine lab investigations were done. Approval of the study was obtained by the local Ethical Committee. Post-operative complications, postoperative pain, frequency and pattern of cardiovascular complications, frequency and pattern of respiratory complications were evaluated and compared between thegroups
Result: In both groups female were predominant. In this study haemodynamic status (Heart rate, SBP, DBP, MBP) in different phases of anaesthesia, surgery and postoperative follow-up (at 4th hour, 8th hour, and 12th hour) has been observed.
Conclusion: This study confirms the feasibility and safety of laparoscopic cholecystectomy is better than open technique in terms of attenuation of better haemodynamic stability, better postoperative pain control and less requirement of analgesia.

Authors: Panferov Dmitry , Averin Alexander 
Published: March 2021

Relevance and novelty. The article examines the issues related to the marketing activities of Russian football clubs in order to identify patterns in this process, as well as assessing the prospects for an integrated approach to evaluating such strategies in modern conditions, in particular, solving the issue of maximizing the effectiveness or efficiency and increasing the attractiveness of Russian football clubs in the international arena.
Justification for the study. Therefore, it is the actions of specific specialists that largely determine how exactly a football club positions itself in the external environment, and also with the help of which tools it solves the problems of increasing the brand’s popularity and attracting fans to stadiums, which directly contribute to the increase in sales of related products to clubs. Marketing management in a football club as well as in companies of other industries should be based on a marketing strategy that should solve a number of specific issues and ensure that the football club is stable in the external environment even in times of crisis. In this regard, the relevance of theoretical and practical research of this problem cannot be questionable.
The purpose of this study was to investigate how Russian football clubs deal with marketing activities in the new reality and consider the ways of optimizing their work.
Methods. The main research methods were literary review, analysis and synthesis of information, modeling and statistical analysis.
Results. As a result of the work, it was concluded that a marketing strategy is necessary for every football club, since it can be used not only to generate new ways of interacting with stakeholders, but also to create a good idea of the brand and ensure its promotion with much lower costs and problems. and also evaluate the effectiveness of brand communications. Realizing that organizational efficiency and effectiveness to a large extent depends not only on titles won, but also on financial performance, fan base growth, as well as the number of followers in social networks, which then turn into loyal fans, we can conclude that for a correct and adequate assessment of the club's marketing strategy and its overall activities requires a system that will consider these, as well as unnamed, but no less important, indicators.
Conclusion. Based on the research, it is necessary to understand that the marketing strategy of a football club can significantly facilitate its task of increasing material well-being, as well as provide audience growth in the stands and brand recognition not only in the territory of a particular country, but also beyond its borders.

Background and Objective: Glucose fluctuation (GF) has been reported to induce renal injury and diabetic nephropathy (DN). However, the mechanism still remains ambiguous. Mitochondrial energy metabolism, especially aerobic glycolysis, has been a hotspot of DN research for decades. The activation of HIF-1α/miR210/ISCU/FeS axis has provided a new explanation for aerobic glycolysis. Our previous studies indicated quercetin as a potential therapeutic drug for DN. This study aims to evaluate levels of aerobic glycolysis and repressive effect of quercetin via HIF-1α/miR210/ISCU/FeS axis in a cell model of GF.Methods: The mouse glomerular mesangial cells (MCs) were exposed in high or oscillating glucose with or without quercetin treatment. Cell viability was measured by CCK8 assay. Aerobic glycolysis flux was evaluated by lactate acid, pH activity of PFK. Apoptosis level was confirmed by Annexin V-APC/7-AAD double staining and activity of caspase-3. TNF-α and IL-1β were used to evaluate inflammation levels.Results: GF deteriorated inflammation damage and apoptosis injury in MCs, while quercetin could alleviate this GF-triggered cytotoxicity. GF intensified aerobic glycolysis in MCs and quercetin could inhibit this intensification in a dose-dependent manner. Quercetin prevented activities of two FeS-dependent metabolic enzymes, aconitase, and complex I, under GF injury in MCs. The mRNA expression and protein contents of HIF-1α were increased after GF exposure, and these could be alleviated by quercetin treatment. Knockdown of ISCU by siRNA and Up-regulating of miR-210 by mimic could weaken the effects of quercetin that maintained protein levels of ISCU1/2, improved cell viability, relieved inflammation injury, decreased apoptosis, and reduced aerobic glycolysis switch in MCs.Conclusion: Quercetin antagonizes GF-induced renal injury by suppressing aerobic glycolysis via HIF-1α/miR-210/ISCU/FeS pathway in MCs cell model. Our findings contribute to a new insight into understanding the mechanism of GF-induced renal injury and protective effects of quercetin.

Background: There is a need for prospective studies investigating substance use variations in mild COVID-19 patients. These individuals represent the majority of patients affected by the disease and are routinely treated at home, facing periods of quarantine.Methods: This was a retrospective cohort study. All people who tested positive for COVID-19 and classified as mild cases (i.e., no alarm sign/symptom, no need for in-person consultation) during the treatment in the public health system of a Brazilian city with around 160,000 inhabitants were monitored by phone for all the COVID-19 symptoms listed by the Centers for Disease Control and Prevention (CDC) during the active phase of the disease (i.e., no longer experiencing symptoms, up to 14 days in mild cases). After this phase (median = 108 days after intake, IQR = 76–137), we asked these patients who were classified as experiencing mild COVID-19 (n = 993) about last-month substance use in three time-points: pre-COVID, just after COVID-19 acute phase (post-COVID acute phase) and in the period before survey (post-COVID follow-up phase).Results: The number of COVID-19 symptoms was not associated with pre- or post-infection substance use. Pre-COVID alcohol and non-medical benzodiazepine use were associated with specific COVID-19 symptoms. However, sensitivity analyses showed that such associations could be explained by previous psychiatric and medical profiles. Alcohol and tobacco use decreased and non-medical analgesics increased in the post-COVID acute phase. However, just alcohol use remained lower in the post-COVID follow-up period. Higher pre-COVID levels of tobacco and alcohol were associated with post-COVID follow-up cannabis and non-medical analgesic use, respectively. Non-medical benzodiazepine use had positive and negative bi-directional associations with cannabis and non-medical analgesic use, respectively.Conclusion: We were not able to find specific associations between substance use and COVID-19 symptomatology in the present study. Patients with mild COVID-19 should be monitored for substance use in the post-COVID-19 period, and preventive interventions for non-medical analgesic use should be implemented. Focused preventive interventions increasing the perceived risks of cannabis and non-medical benzodiazepine and analgesic use among people experiencing mild COVID-19 that reported previous substance use could be useful.
