Surveillance of Vibrio spp. in Penaeus monodon Collected from Shrimp Pond of Satkhira, Bangladesh

Vibrio is the most common genera associated with crustaceans and often causing significant economic losses. Many Vibrio species are pathogenic to human and have been implicated in food borne diseases. The present study was conducted to identify Vibrio spp. from the tiger shrimp (Penaeus monodon) of shrimp pond at Satkhira, Bangladesh. A total number of 33 Vibrio species isolates were identified from 20 shrimp samples through a series of morphological, physiological and biochemical tests. The work reports the prevalence of Vibrio spp. in the pond environments and the existence of three Vibrio species such as V. alginolyticus, V. parahaemolyticus and V. harveyi were identified. In the study of antibiogram, all isolates were shown 100% sensitive to streptomycin, ciprofloxacin and chloramphenicol. Maximum 41% isolates were shown resistant to co-trimethaxozole whereas 30% and 24% resistant to azithromycin and novobiocin respectively

Observation of cardiac profile among the adult population of Sreemangal

Background: Cardiovascular diseases are a leading cause of morbidity and mortality worldwide. The prevalence and risk factors of CVDs vary across different populations and regions. This study aimed to observe the cardiac profile among the adult population of Sreemangal, Bangladesh, to identify the prevalence and risk factors of CVDs in this population. Methods: This prospective observational study was conducted over a six-month period at a public health camp in Sreemangal, Bangladesh. A total of 137 adult participants were purposively selected. Data were collected through a structured questionnaire and physical examination, including measurements of blood pressure and laboratory analysis of blood samples. Results: The study found that 44.53% of participants had elevated blood pressure, and 21.90% had stage 1 hypertension. Interestingly, 36.50% of participants were unaware of their hypertension status. Furthermore, 26.28% of participants had a known history of diabetes, but blood glucose level analysis revealed an additional 14.85% of participants were prediabetic, and 6.93% were diabetic based on fasting blood glucose levels. A statistically significant association was found between increasing age and the stage of hypertension (p<0.001), and between fasting and normal blood glucose levels and the stage of hypertension (p<0.005 and p<0.05, respectively). Conclusions: The findings of this study underscore the need for targeted interventions to prevent and manage CVDs in the adult population of Sreemangal, Bangladesh. These interventions should include regular screening for CVD risk factors, health education to increase awareness of these risk factors, and strategies to promote healthy lifestyle behaviors

Review on carbonation study of reinforcement concrete incorporating with bacteria as self-healing approach

This study carried out a comprehensive review to determine the carbonation process that causes the most deterioration and destruction of concrete. The carbonation mechanism involved using carbon dioxide (CO2 ) to penetrate the concrete pore system into the atmosphere and reduce the alkalinity by decreasing the pH level around the reinforcement and initiation of the corrosion process. The use of bacteria in the concrete was to increase the pH of the concrete by producing urease enzyme. This technique may help to maintain concrete alkalinity in high levels, even when the carbonation process occurs, because the CO2 accelerates to the concrete and then converts directly to calcium carbonate, CaCO3 . Consequently, the self-healing of the cracks and the pores occurred as a result of the carbonation process and bacteria enzyme reaction. As a result of these reactions, the concrete steel is protected, and the concrete properties and durability may improve. However, there are several factors that control carbonation which have been grouped into internal and external factors. Many studies on carbonation have been carried out to explore the effect of bacteria to improve durability and concrete strength. However, an in-depth literature review revealed that the use of bacteria as a self-healing mechanism can still be improved upon. This review aimed to highlight and discuss the possibility of applying bacteria in concrete to improve reinforcement concrete

Overview On Surgical Management Of Overactive Bladder

Overactive bladder syndrome is a persistent and incapacitating disorder that has profound medical, psychological, and social implications, greatly impacting the wellbeing of countless individuals globally. A significant number of individuals experience urine urgency, which can be extremely bothersome. The primary indicator of overactive bladder (OAB) is a sense of urgency, often accompanied by increased urine frequency and nocturia. After ruling out other medical conditions with similar symptoms, the initial approach to managing OAB is providing guidance on fluid consumption and bladder training. If needed, antimuscarinic medicines may be added as a supplement. If patients have significant distress from OAB symptoms even after maximizing medicinal treatment, they may choose to undergo invasive procedures. There is currently a limited understanding of the hierarchical structure of central nervous system control. However, the use of functional imaging is starting to reveal the difficulties that need to be addressed in this area. Current research is exploring the use of botulinum neurotoxin-A injection, oral β3-adrenergic agonists, and innovative methods for nerve stimulation as potential therapies. The inherent subjectivity of urine urgency, the absence of animal models, and the complex pathophysiology of overactive bladder (OAB) pose substantial obstacles to achieving effective clinical therapy

Organ-specific toxicity evaluation of stearamidopropyl dimethylamine (SAPDMA) surfactant using zebrafish embryos

Surfactants are widely used in the industry of detergents, household products, and cosmetics. SAPDMA is a cationic surfactant that is used mostly in cosmetics, conditioning agents and has recently gained attention as a corrosion inhibitor in the sea pipelines industry. In this regard, literature concerning the ecotoxicological classification of SAPDMA on aquatic animals is lacking. This study aims to evaluate the potential ecotoxicity of SAPDMA using the aquatic zebrafish embryo model. The potential toxic effects of SAPDMA were assessed by different assays. This includes (i) mortality/survival assay to assess the median lethal concentration (LC50); (ii) teratogenicity assay to assess the no observed effect concentration (NOEC); (iii) organ-specific toxicity assays including cardiotoxicity, neurotoxicity (using locomotion assay), hematopoietic toxicity (hemoglobin synthesis using o-dianisidine staining), hepatotoxicity (liver steatosis and yolk retention using Oil Red O (ORO) stain); (iv) cellular cytotoxicity (mitochondrial membrane potential) by measuring the accumulation of JC-1 dye into mitochondria. Exposure of embryos to SAPDMA caused mortality in a dose-dependent manner with a calculated LC50 of 2.3 mg/L. Thus, based on the LC50 value and according to the Fish and Wildlife Service (FWS) Acute Toxicity Rating Scale, SAPDMA is classified as “moderately toxic”. The No Observed Effect Concentration (NOEC) concerning a set of parameters including scoliosis, changes in body length, yolk, and eye sizes was 0.1 mg/L. At the same NOEC concentration (0.1 mg/L), no organ-specific toxicity was detected in fish treated with SAPDMA, except hepatomegaly with no associated liver dysfunctions. However, higher SAPDMA concentrations (0.8 mg/L) have dramatic effects on zebrafish organ development (eye, heart, and liver development). Our data recommend a re-evaluation of the SAPDMA employment in the industry setting and its strictly monitoring by environmental and public health agencies

Quality of Sleep and Its Effect on Glycemic Control

Diabetes mellitus (DM) is a widespread illness that affects around 347 million individuals globally. DM not only has many clinical implications but also has a detrimental impact on the quality of sleep in patients. Insufficient sleep quality hinders the proper regulation of blood sugar levels, which is considered a fundamental aspect of managing diabetes. It also has other harmful repercussions that significantly affect one's overall quality of life. Increasing data suggests that sleep disturbances and sleep deprivation have an impact on glucose metabolism and insulin resistance. Simultaneously, changes in glucose metabolism can potentially affect the quality of sleep. The association between T2DM and sleep-disturbed breathing has been thoroughly investigated. Individuals diagnosed with T2DM exhibit a remarkably elevated incidence of obstructive sleep apnea, which subsequently leads to suboptimal management of blood sugar levels. Conversely, the correlation between T1DM and sleep has not been well-studied

AEO-7 surfactant is “super toxic” and induces severe cardiac, liver and locomotion damage in zebrafish embryos

© 2020, The Author(s). Background: Fatty alcohol polyoxyethylene ether-7 (AEO-7), a non-ionic surfactant, has recently been receiving extensive attention from the ocean pipeline industry for its ability to inhibit corrosion. However, the present lack of information concerning the potential environmental toxicity of AEO-7, especially towards aquatic organisms, is a major impediment to its wider application. Here, we assess potential adverse effects of AEO-7 on zebrafish embryos employing a variety of assays, including (i) a mortality/survival assay which allowed the median lethal concentration (LC50) to be calculated; (ii) a teratogenicity assay on the basis of which the no observed effect concentration (NOEC) was determined; and (iii) specific assays of cardiotoxicity, neurotoxicity (based on locomotion), hematopoietic toxicity (the level of hemoglobin as revealed by o-dianisidine staining) and hepatotoxicity (liver steatosis and yolk retention examined by staining with Oil Red O). Results: AEO-7 caused mortality with a calculated LC50 of 15.35 μg/L, which, according to the U.S. Fish and Wildlife Service (USFWS) Acute Toxicity Rating scale, should be considered “super toxic”. Although at its NOEC (0.8 μg/L), there were no signs of significant teratogenicity, cardiotoxicity, or hemopoiesis toxicity, 3.2 µg/L AEO-7 exerted dramatic detrimental effects on organ development. Conclusion: On the basis of these findings, we recommend that the industrial usage and environmental impact of AEO-7 be re-evaluated and strictly monitored by environmental and public health organizations

‘NOT A RELIGIOUS STATE’ A study of three Indonesian religious leaders on the relation of state and religion

This article explores the concept of a ‘secular state’ offered by three Indonesian religious leaders: a Catholic priest, Nicolaus Driyarkara (1913–1967), and two Muslim intellectuals who were also state officials, Mukti Ali (1923–2004) and Munawir Sjadzali (1925–2004). All three, who represented the immediate generation after the revolution for Indonesian independence from the Dutch (1945), defended the legitimacy of a secular state for Indonesia based on the state ideology Pancasila (Five Principles of Indonesia). In doing so, they argued that a religious state, for example an Islamic state, is incompatible with a plural nation that has diverse cultures, faiths, and ethnicities. The three also argued that the state should remain neutral about its citizens’ faith and should not be dominated by a single religion, i.e. Islam. Instead, the state is obliged to protect all religions embraced by Indonesians. This argument becomes a vital foundation in the establishment of Indonesia’s trajectory of unique ‘secularisation’. Whilst these three intellectuals opposed the idea of establishing a religious or Islamic state in Indonesia, it was not because they envisioned the decline of the role of religion in politics and the public domain but rather that they regarded religiosity in Indonesia as vital in nation building within a multi-religious society. In particular, the two Muslim leaders used religious legitimacy to sustain the New Order’s political stability, and harnessed state authority to modernise the Indonesian Islamic community
