The level of heavy metals above the permissible limit is toxic to human being as well as to animal welfare. The heavy metals enter the surrounding environment by natural and though anthropogenic activities. Soil erosion, natural weathering, mining, industrial effluents, urban runoff, sewage discharge, inorganic fertilizers, insecticides, herbicides, industrial emissions and transportations are some of the various sources of heavy metals induced to the environment, waterbody, soil and foods. Many instrumental analytical methods may be employed to measure the concentration of heavy metals in various samples. The most common techniques are atomic absorption spectrometry (AAS); atomic emission/ fluorescence spectrometry (AES/AFS); inductively coupled plasma mass spectrometry (ICP-MS); inductively coupled plasma optical emission spectrometry (ICP-OES); neutron activation analysis (NAA), X-ray fluorescence (XRF); and anodic striping voltammetry (AVS). The detection level of metals quantification depends on the instrument, method extractions and speciation. There are physical, chemical and biological techniques of heavy metals remediations in soil and human bodies. Biochar is one of the organic materials reduce the level of heavy metals, the plant species such as: Salix spp. (Salix viminalis, Salix fragilis), Castor (Ricinus communis), Corn (Zea mays),Populus spp. (Populus deltoides, Populus nigra, Populus trichocarpa), Jatropha (Jatropha curcas L.), Populus deltoides, Brassica juncea, Astragalus bisulcatus, Populus canescens can also remediate heavy metals from the contaminated soil. Chelate therapy ridding the body heavy metals with a chemical like Ethylene Diamine Tetraacetic Acid (EDTA) effective chelation of removing metals from body blood. Due to the increasing trend of HMs contamination, the negative impact on plants, environments and other organisms, it is important to mitigate the toxicity by developing effective and environmentally safe technologies. This paper therefore gives highlights of heavy metals sources, techniques of analysis and remediations.

This research article attempts to explore the socialist and revolutionary elements as portrayed in the selected poetry of one of the most renowned poets of Turkey, Nazim Hikmet. Nazim’s poetry embodies the echoes of his fellowmen where the people of his country do not seem to conform the dictating ruling class and display their protest against the authoritarian rulers. Marxist theory of Social Realism has been employed so as to illustrate the essence of social reality from the selected poetry of Nazim Hikmet. Social Realism holds that every reality is directly associated with society and literature cannot be separated from the social threads. Nazim in his poems challenges the then system of his country and expresses his urge for revolution to transform the downtrodden society from the shattered position to an uplifted and a newer one. His poetry is a promise to human reality and showcases the human rights plea in broader sense.

Training dental students is a complex process as it requires the acquisition of fine motor skills, and hand-foot and eye coordination to perform clinical work, in addition to the attainment of knowledge. Awareness of limitations of conventional simulators that have been used for pre-clinical training for this purpose, has paved way for digital dentistry as the new pedagogical paradigm that offers multiple advantages over conventional dental teaching methods (Zafar et al., 2020). Digital innovations including virtual reality (VR) and augmented reality (AR) are becoming more prevalent in dentistry (Dutã et al., 2011 in Zafar et al., 2020). This paper reviews some of the recent methods such as computer assisted simulators, virtual patients, virtual teeth, use of MultiUser Virtual environment, etc., and highlights the benefits of using these for the preclinical training in dental education. The need for the new age facilitators to adopt to and employ the newer technology based methods of instruction has also been emphasized.

Background: Apheresis is a blood transfusion process that allows a donor to give specific blood components like platelets, RBCs, or plasma to the receivers. During this procedure, the rest blood components are returned to the donors. For safe and effective apheresis platelet transfusion, profiling of donors and receivers or primary information of them is very important. In Bangladesh, we have not enough research-based information regarding these issues. Aim of the study: The aim of this study was to analyze the profile of apheresis platelet donors and receivers who were cancer patients. Methods: This was a retrospective observational study which was conducted in the Department of Transfusion Medicine, National Institute of Cancer Research and Hospital (NICRH), Mohakhali, Dhaka, Bangladesh during the period from January 2018 to December 2019. In total 210 platelet donors and 210 platelet receivers through apheresis procedure were enrolled as the study population. The ethical committee of the mentioned hospital had approved this study. Before starting data collection, properly written consent was taken from all the participants. All data were processed, analyzed, and disseminated by MS Office and SPSS version 20 as per need. Result: In this study, the mean age of the donor was 26.62 ± 5.86 years. Only one donor was female (0.5%) whereas 95.5% of donors were male. As platelet count, below 2 lacs, above 2 lacs, above 3 lacs, and above 4 lacs were in 10%, 72.4%, 16.7%, and 1% donors respectively. For 100% donors, it was a single donation. On the other hand, the mean age of the receivers was 26.94 ± 15.55 years. We observed, 69% of receivers were male whereas 31% were female. In this study, as platelet count of receivers, we found <10,000/lac, 10,000-30,000/lac and 30,001-50,000/lac platelets among 15.7%, 61.9% and 22.4% receivers respectively. The majority of the receivers were with AML (Acute Myeloid Leukemia) which was found among 68%. As a total number of apheresis, a single number was found in 13% and multiple numbers were found in 36% of receivers. In 82% of receivers, history of chemotherapy and in 18% receiver’s history of chemotherapy as well as radiotherapy were found. Conclusion: In Bangladesh basically males are the prominent part of platelet donation through apheresis procedure. Although young males play a vital role in apheresis platelet donation, younger children and adolescents are the basic receivers here, a large number of healthy young women as potential blood donors are still out of platelet donation procedure in Bangladesh. Necessary motivational education could make them interested as platelet donors in the mainstream blood transmission system in near future.

For management and treatment of diabetes several medicinal plants are used worldwide as well as these are being utilized customarily for the management of diabetes in human. The current study explored Stevia (Stevia rebaudiana) and gurmar (Gymnema Sylvestre) to determine their hypoglycemic activity compared to the standard drug metformin. Streptozotocin was used to induce diabetes in rats (55 mg/kg) intraperitoneal. For a time period of 60 days stevia (100mg/kg), gurmar (500mg/kg), and their combination (500mg/kg) was administered orally as well as metformin at the rate of 800μg/kg after 2 weeks of STZ injection. Hypoglycemic effects were shown best in combined stevia-gurmar extract than the individual doses of stevia and gurmar. (OGTT) oral glucose tolerance test and measurement of blood glucose levels were assessed. Reduction in body weight by STZ was also found to increase in all rats except stevia treatment. In conclusion, the extracts of stevia and gurmar showed hypoglycemic effect as well as improving body weight effects in diabetic rats. Therefore, it can be suggested that stevia as well as gurmar extracts have a potential in preventing diabetes and can be used as antidiabetics in herbal medicine.

Maxillary central and lateral individual zirconia crowns were manufactured and cemented with dual-cure resin cement. Harmony with the existing shade of all teeth was achieved. The patient reported improved self-esteem and better relationship with their students as well as social interactions.

The irruption and global spread of pandemic Covid-19 since the end of 2019 has led to a serious and a comprehensive chaos affecting almost all aspects of the life. The consequence resulted in an international concerns where the control of the pandemic went out of control by the World Health Organizations (WHO) as well as the developed countries. The pandemic looked as a biological war being launched by the giant countries USA and China particularly against the elderly people to trim down the world populations of them due to the increase the life span in the well developed countries and the increase in rate of birth in developing countries. The overall mortality has exceeded a few millions without any ironic action to stop spreading the virus nor protecting the lives. Most of the modern global measurements taken so far to overcome the crisis have failed to contain the pandemic. While all the man-made laws failed to contain the pandemic the measurements driven from the activation and application of the divine laws, represented in Islamic values e.g. faith values, could guarantee the overcome the worldwide crisis.

Pulmonary tuberculosis is the second most common infectious killer, claiming more than one million lives each year. The tuberculosis is common worldwide, but it is endemic in some parts of the world, such as Asia and Africa. The documented cases of endobronchial tuberculosis are less than that the magnitude of the problem because bronchoscopy and high resolution computed tomography is usually not performed in all cases of suspected or confirmed pulmonary tuberculosis. The complications and late sequelae are major challenges where infrastructure and expertise in Interventional bronchoscopy are warranted.

Radish is consumed and cultivated globally and is reflected as a part of human-diet, although this root vegetable is not common in many populations. Different varieties of radish have the different soil and climate requirements for better growth and yield but the most beneficial and important agro-technique is nutrition for better performance. For better quality and optimal radish production, fertilization by organic, inorganic and bio-fertilizers are very important constituents.
