The use of fish silage to increase feed efficiency and growth of grouper (Epinephelus coioides) in floating net cages

This study aimed to investigate the efficiency of fish silage mixed in compounded diets on growth and survival rate of grouper (Epinephelus coioides). Grouper (2,34±0,24 cm, and 4,17±1,82 g) were divided into four groups and cultivated in 1x1x1,5 m floating net cages. Each group fed with compounded diets containing 0, 1, 3 and 5 g/kg fish silage diet twice daily. Fish were sampled for growth performances and feed efficiency at 14 days interval for 10 weeks. Results indicated that compounded diets at 1 and 3 g/kg silage affected the growth rate. Total length, specific growth rate and weight gain significantly increased in fish received 1 and 3 g/kg silage diets. The feed intake seen to be highest in groups administered 3 g/kg silage, whereas the best feed conversion ratio was found in fish fed 1 g/kg silage. Thus, this study indicated that using fish silage in compounded diets may affect feed efficiency and growth performances of grouper juveniles.Keywords:Artificial dietFeedingFish silageGrouperNet cage

Developing a forecasting model for cholera incidence in Dhaka megacity through time series climate data.

Cholera, an acute diarrheal disease spread by lack of hygiene and contaminated water, is a major public health risk in many countries. As cholera is triggered by environmental conditions influenced by climatic variables, establishing a correlation between cholera incidence and climatic variables would provide an opportunity to develop a cholera forecasting model. Considering the auto-regressive nature and the seasonal behavioral patterns of cholera, a seasonal-auto-regressive-integrated-moving-average (SARIMA) model was used for time-series analysis during 2000-2013. As both rainfall (r = 0.43) and maximum temperature (r = 0.56) have the strongest influence on the occurrence of cholera incidence, single-variable (SVMs) and multi-variable SARIMA models (MVMs) were developed, compared and tested for evaluating their relationship with cholera incidence. A low relationship was found with relative humidity (r = 0.28), ENSO (r = 0.21) and SOI (r = -0.23). Using SVM for a 1 °C increase in maximum temperature at one-month lead time showed a 7% increase of cholera incidence (p < 0.001). However, MVM (AIC = 15, BIC = 36) showed better performance than SVM (AIC = 21, BIC = 39). An MVM using rainfall and monthly mean daily maximum temperature with a one-month lead time showed a better fit (RMSE = 14.7, MAE = 11) than the MVM with no lead time (RMSE = 16.2, MAE = 13.2) in forecasting. This result will assist in predicting cholera risks and better preparedness for public health management in the future

Pesantren students’ religious beliefs and attitudes toward learning English in Indonesia

Some students in Indonesian Pesantren (Islamic Boarding School) reported negative attitudes toward English as lingua Franca due to their environmental background, socio-cultural awareness, and identities. However, there are limited studies conducted in investigating their religious beliefs as the basis of pesantren students' attitudes toward learning English. Thus, this study aimed to investigate Indonesian pesantren students' attitudes toward learning English based on their religious beliefs and practices. The survey method was addressed to 250 respondents from three pesantren in Central Java. The researchers used a close-ended questionnaire adapted from the Attitudes/motivation Test Battery and 12 items focusing on the students' religious beliefs toward English. Besides, semi-structured interviews were conducted to get a deep understanding. This research employed one-way ANOVA and revealed a significant difference of the students' educational background in the pesantren on the mean of L2 attitudes, F = (14.40), Sig. = .000. The qualitative analysis revealed that ethnoreligious background shaped the positive attitudes of pesantren students toward English. Although most English speakers were non-believers, the students believed that learning English does not indicate the equal faith of non-believers and threat their religious identity. Furthermore, the participants claimed that learning English is important and not forbidden by religious teaching. They also thought that learning English can be considered as a kind of worship depending on the learner's intention, such as for communicating Islamic values to non-believers, future education, and improving careers

Unilateral ischemic central retinal vein occlusion in a young healthy adult: a case report

Central retinal vein occlusion (CRVO) is an obstruction of central retinal vein due to the impingement from the fellow central retinal artery. It is the second most common retinal vascular disease after diabetic retinopathy. Risk factor of CRVO includes diabetes mellitus, hypertension, hyperlipidemia, cardiovascular disease, male gender and age above 50 years; with 90% of the cases occurred in individual aged 55 years and above. We report a rare case of left eye ischemic CRVO in a 24-year-old healthy gentleman who later on found out to have hypercholesterolemia. He presented with a sudden onset of reduced vision of his left eye. Examination revealed visual acuity (VA) of the left eye was 6/120. Fundus examination showed marked papilloedema with dilated and tortuous blood vessels and extensive flame-shaped hemorrhages with cotton wool spots in all four retinal quadrants. There was a presence of macular edema as well. The ancillary tests confirmed the diagnosis of left eye ischemic CRVO with significant macular edema. The blood investigation revealed elevated cholesterol levels. For treatment, 6 times of monthly intravitreal Ranibizumab injections were planned for the macular edema and oral Atorvastatin 40 milligrams daily was started. Following the intravitreal Ranibizumab injection, his VA has significantly improved with a reduction of macular edema. This report highlights the importance of prompt diagnosis and investigation of CRVO, especially in the younger age group. Early treatment of macular edema secondary to CRVO is able to reduce the edema thus leads to VA improvement

The outcome of Descemet membrane endothelial keratoplasty (DMEK) with different tamponade material.

OBJECTIVE: To compare the outcome of different tamponade material in Descemet membrane endothelial keratoplasty (DMEK). METHODS: Retrospective, interventional case series that includes 8 patients underwent DMEK performed by a single surgeon within Covid-19 pandemic period. All donor tissues were stripped by the operating surgeon with endothelial cell density of > 2400 cells/mm2. The tamponade material used were air in 2 patients, 20% sulfur hexafluoride (SF6) gas in 3 patients and 12% perfluoropropane (C3F8) gas in 3 patients. The main outcomes were graft detachment rate, rebubbling rate and graft survival rate. RESULTS: The overall graft detachment rate was 25% (2 patients). The graft detachment rate was 0% in 20% SF6 gas group compared to 50% (1 patient) from air tamponade group and 33.3% (1 patient) from 12% C3F8 gas group (p<0.05). The patient from air group underwent rebubbling twice while another patient from 12% C3F8 gas group underwent once. The overall survival rate was 75% (6 patients). All of them did not have graft detachment. CONCLUSION: 20% SF6 gas provides superior tamponade effect compared to both air and 12% C3F8 gas. The detachment rate influenced graft survival. Air tamponade showed higher rebubbling rate

Cardiac sodium channelopathies

Cardiac sodium channel are protein complexes that are expressed in the sarcolemma of cardiomyocytes to carry a large inward depolarizing current (INa) during phase 0 of the cardiac action potential. The importance of INa for normal cardiac electrical activity is reflected by the high incidence of arrhythmias in cardiac sodium channelopathies, i.e., arrhythmogenic diseases in patients with mutations in SCN5A, the gene responsible for the pore-forming ion-conducting α-subunit, or in genes that encode the ancillary β-subunits or regulatory proteins of the cardiac sodium channel. While clinical and genetic studies have laid the foundation for our understanding of cardiac sodium channelopathies by establishing links between arrhythmogenic diseases and mutations in genes that encode various subunits of the cardiac sodium channel, biophysical studies (particularly in heterologous expression systems and transgenic mouse models) have provided insights into the mechanisms by which INa dysfunction causes disease in such channelopathies. It is now recognized that mutations that increase INa delay cardiac repolarization, prolong action potential duration, and cause long QT syndrome, while mutations that reduce INa decrease cardiac excitability, reduce electrical conduction velocity, and induce Brugada syndrome, progressive cardiac conduction disease, sick sinus syndrome, or combinations thereof. Recently, mutation-induced INa dysfunction was also linked to dilated cardiomyopathy, atrial fibrillation, and sudden infant death syndrome. This review describes the structure and function of the cardiac sodium channel and its various subunits, summarizes major cardiac sodium channelopathies and the current knowledge concerning their genetic background and underlying molecular mechanisms, and discusses recent advances in the discovery of mutation-specific therapies in the management of these channelopathies

In vitro effects of zinc on the cytokine production from peripheral blood mononuclear cells in patients with zinc allergy.

Metals, such as nickel, cobalt, chromium and zinc, are ubiquitous in the environment. Systemic reactions, including hand dermatitis and generalized eczematous reactions, can be caused by the dietary ingestion of metals. In this study, we aimed to determine whether the cytokine production from peripheral blood mononuclear cells (PBMCs) obtained from zinc allergy patients can be used as a sensitive marker to investigate zinc-allergic contact dermatitis. The diagnosis of sensitivity to metal was made based on the results of a metal patch test. The PBMCs were stimulated with various concentrations (5-100 μM) of zinc sulfate (ZnSO4) for 24 h. The culture supernatants were collected and analyzed using ELISA for measurement of the cytokine production. The levels of IFN-γ, TNF-α, IL-1β, IL-5, IL-13 and MIF were significantly higher in the zinc-allergic patients (n = 5) than in the healthy controls (n = 5) at 100 μM of ZnSO4 stimulation. Although, patch testing is considered as standard test to diagnose metal allergy but false-positive and -negative reactions may limit its use in conditions of existing dermatitis. Therefore, this study suggest that in support of patch testing the determination of cytokine production using PBMCs cultures would be helpful for making an early diagnosis of such conditions
