    Abstract: Background: Helicobacter pylori (H. pylori) remains one of the most common worldwide human infections and is associated with a number of important upper gastrointestinal (GI) conditions including chronic gastritis, peptic ulcer disease, gastric carcinoma and special type of lymphoma. Anaemia is a common disorder in developing countries and the commonest cause is iron deficiency. There are many causes for high prevalence of this disorder in our society, many are well-known and investigated while some are new and not well established. Although H. pylori associates peptic ulcers and gastric malignancy can cause bleeding, resulting in iron deficiency, but majority of patients infected with H. pylori does not have ulcer or malignancy. They usually have chronic gastritis that is not associated with GI bleeding. About 35% of iron deficiency anaemia cases remain unexplained after a gastrointestinal evaluation. Recently investigation focused on the role of H. pylori, in the development of extra-gastrointestinal diseases including Iron deficiency anaemia. Methodology: This observational, cross sectional study was carried out at BSMMU, Dhaka from July 2010 to October 2011 to find out the association between H. pylori infection and iron deficiency anemia in Bangladeshi adults. Patients with dyspepsia and indication of upper GI endoscopy were initially enrolled in the study and finally a total of 168 subjects were included based on inclusion and exclusion criteria. Result: Among 168 patients, 105 (62.5%) were male and 63(37.5%) were female with the mean age of 33.25 years. On endoscopy, 147(87.5%) of the patients had normal findings and 21(12.5 %) had erosive gastritis. None of them had hemorrhagic erosive gastritis. Among 168 patients, 115(68.45%) were positive and 53(31.55%) were negative for H. pylori by rapid urease test. In our study, we have found a significant low mean serum ferritin level (P 〈 0.001) in H. pylori infected patients. This result is consistent with most of previous data concerning the effect of H. pylori infection on iron metabolism. This study has also revealed a significant (P 〈 0.001) lower value of mean MCV and MCH in H. pylori positive patients. Regarding hemoglobin value, our study has showed no significant (P 〉 0.05) different in hemoglobin level according to H. pylori status. Conclusion: Though there was no significant low hemoglobin level in our study, mean hemoglobin level was low in H. pylori positive patient. In our study H. pylori was not significantly associated with iron deficiency anemia but it was significantly associated with iron deficiency. J Bangladesh Coll Phys Surg 2020; 38(2): 68-78

    Abstract: Digitalization captures most aspects of human life. New trends in digitalization have a great impact on the retail chain stores; hence, the implementation of artificial intelligence (AI) has somewhat become necessary to cope up with the changing trend in this sector. This case study analyses the use of artificial intelligence in an unstaffed supermarket called LIFVS located at the rural areas of Sweden. As the number of supermarkets was decreasing in the rural areas over the years due to high maintenance costs, many have opted out of business. In response to the situation, Co-founder Daniel Ludh (hereafter Daniel) implemented a sustainable business model using AI, which serves the purpose of supermarket chains meeting the demands of the consumers in the rural areas while keeping the costs truncated. The case also discusses the various challenges an unstaffed supermarket face and highlights the success of LIFVS, paving the path for the future retailers of the industry.

    Abstract: This case study focuses on the impressive work carried out by DataNet. Their dedicated and innovative strategies helped develop the economy of eSwatini (formerly known as Swaziland). This case aims to demonstrate how this ingenious organization promoted eSwatini’s revenue to increase fourfold with DataNet’s advice regarding tax issues. DataNet also successfully executed numerous projects for the government of eSwatini. To name a few, DataNet has implemented the National Fire and Emergency Response System, Customs Automation, Scholarship Systems, as well as Surveillance System— a few of which were milestones for the company and eSwatini’s government. DataNet assimilates services tailored to the client’s needs with their technologies, including Internet of Things, high-performance computing, machine learning, big data platform, and their application on several industries, for example, education, finance, and health security and health. Challenges were encountered by DataNet while working in eSwatini; poor governance, lower Internet penetration rate, and the lack of a skilled workforce were real setbacks. Nonetheless, DataNet has been successful in leaving its mark in over six countries, covering three continents.

    Abstract: SARS-CoV-2 has been highly susceptible to mutations since its emergence in Wuhan, China, and its subsequent propagation due to containing an RNA as its genome. The emergence of variants with improved transmissibility still poses a grave threat to global health. The spike protein mutation is mainly responsible for higher transmissibility and risk severity. This study retrieved SARS-CoV-2 variants structural and nonstructural proteins (NSPs) sequences from several geographic locations, including Africa, Asia, Europe, Oceania, and North and South America. First, multiple sequence alignments with BioEdit and protein homology modeling were performed using the SWISS Model. Then the structure visualization and structural analysis were performed by superimposing against the Wuhan sequence by Pymol to retrieve the RMSD values. Sequence alignment revealed familiar, uncommon regional among variants and, interestingly, a few unique mutations in Beta, Delta, and Omicron. Structural analysis of such unique mutations revealed that they caused structural deviations in Beta, Delta, and Omicron spike proteins. In addition, these variants were more severe in terms of hospitalization, sickness, and higher mortality, which have a substantial relationship with the structural deviations because of those unique mutations. Such evidence provides insight into the SARS-CoV-2 spike protein vulnerability toward mutation and their structural and functional deviations, particularly in Beta, Delta, and Omicron, which might be the cause of their broader coverage. This knowledge can help us with regional vaccine strain selection, virus pathogenicity testing, diagnosis, and treatment with more specific vaccines.

    Abstract: The present experiment was conducted to establish an efficient in vitro regeneration protocol for Alocasia amazonica through indirect organogenesis from young leaf segment. For callus induction, leaf explants were inoculated on MS medium containing different concentrations of 2,4-D. Highest callus induction frequency (90%) was recorded on MS medium supplemented with 4.0 mg/l 2,4-D. Remarkable results on indirect shoot organogenesis and multiplication (86.67%) with maximum shoot number per unit callus (11.64 ± 0.37) and shoot length (10.13 ± 0.24 cm) were observed when the leaf derived callus were transferred on MS medium fortified with 1.5 mg/l BAP and 0.5 mg/l NAA. Additionally, the incorporation of 10% coconut water with the medium showed satisfactory shoot growth and development. The best response towards root induction (85%) was achieved on ½ MS medium fortified with 3.0 mg/l IBA, 2.0 mg/l IAA and 2.0 mg/l NAA with an average 22.20 ± 0.87 roots per unit shoot. Well rooted plantlets were successfully acclimatized to the soil where the survival rate was 90%. Plant Tissue Cult. & Biotech. 32(1): 13-20, 2022 (June)

    Abstract: This is the first attempt to evaluate the impact of four salinity levels on the color parameters, pigments, polyphenols, flavonoids, and antioxidant capacities of four promising A. lividus genotypes. The color parameters, such as the yellowness/blueness (b*) and the chroma (C*); the antioxidant components, such as the polyphenols and flavonoids; and the antioxidant capacities of the leaves were remarkably increased by 39, 1, 5, 10 and 43%, respectively, at 50 mM of NaCl, and by 55, 5, 60, 34, 58 and 82%, respectively, at 100 mM NaCl concentrations. The green tower and SA6 genotypes were identified as tolerant varieties. The total phenolic content (TPC) and the total flavonoid content (TFC) played vital roles in scavenging reactive oxygen species (ROS), and they would be beneficial for the human diet and would serve as good antioxidants for the prevention of aging, and they are also essential to human health. A correlation study revealed the strong antioxidant capacities of the pigments and antioxidant components that were studied. It was revealed that A. lividus could tolerate a certain level of salinity stress without compromising the antioxidant quality of the final product. Taken together, our results suggest that A. lividus could be a promising alternative crop for farmers, especially in saline-prone areas in the tropical and subtropical regions.

    Abstract: Cellulases are used in textile, pulp and paper, brewery and wine, sugars, and ethanol industries. Four fungal isolates obtained from organic municipal solid wastes (OMSW) were selected based on their cellulolytic activity on carboxymethyl cellulose (CMC) agar medium. Based on the internal transcribed spacer (ITS) sequence of the ribosomal DNA, the four cellulolytic isolates were identified as Aspergillus fumigatus AKAL1, Aspergillus oryzae AKAL4, Aspergillus flavus AKAL8, and Aspergillus flavus AKAL9. After 9 days of fermentation at 30°C and pH 6.5 under 110 rpm agitation, these isolates produced the maximum amount of cellulase. The cellulase showed optimum activity at temperature 35–40°C and pH 6.0–7.0 and was stable for 1 h at 25–45°C and pH 5.0–7.0. The Mg 2+ and Zn 2+ significantly increased but Hg 2+ , K + , and Ca 2+ severely repressed the cellulase activity. Degradation of filter papers and bio‐stoning of denim was successfully done with the crude cellulase. An endo‐β‐1,4‐glucanase was isolated and characterized from Aspergillus isolates. Genome‐wide analysis revealed that the genomes of A. oryzae , A. fumigatus , and A. flavus , the pertinent species of the fungal isolates, had 23, 25, and 22 cellulase genes, respectively. Phylogenetic analysis revealed that the cellulases in these fungal species were divided into three major groups, and the isolated endo‐β‐1,4‐glucanase clustered to Group II. Ten different motifs are present in cellulases of the three species. Results herein provide a valuable resource for understanding cellulase genes in Aspergillus species and potential application of cellulase in textile and fermentable sugars production industries.
