Soil Erosion is the detachment, transportation and deposition of soil sediment from one place to another. This has led to loss of lives and infrastructure in many parts of Nigeria. Soil properties play a role in it vulnerability and extent to erosion. This study aims to evaluate selected physical properties as they interact to cause erosion in the study area. The study was conducted in 2012 in a gully site in relation to its potential to erodibility of gully channel. This was done by collection of various soil samples at different depth followed by laboratory analysis to determine the plastic limit, moisture content and other engineering properties. The Results indicated that the soil samples have Atterberg limit that might be considered low, while liquid limit (LL) ranged from 25 – 30, the plasticity index (PI) ranged from 1 – 5%, which suggested that the soils are slightly plastic. Moisture content was moderate. The soil properties investigated played a major role in exacerbating the gully erosion in the area, therefore, the existing culvert should be redesigned and reconstructed taking appropriate consideration of the underlying soil properties

Published: June 2021

Root-knot nematodes have been implicated in poor growth and death of trees in the nursery and newly established forest plantations. Cultivating resistant tree species is one of the viable methods in the management of nematode pests once they are identified. A pot experiment laid out in completely randomized design was conducted to screen fifteen selected tree seedlings for resistance to Meloidogyne incognita. Each tree seedling was replicated eight times and was grown on a steam-sterilized soil. The seedlings were inoculated each with 7,000 eggs of Meloidogyne incognita at four weeks after planting. Data were collected on plant height and stem girth at 12 weeks after inoculation. At termination, data were also collected on gall index (GI), final nematode population (Pf) and reproductive factor (RF). Data were analyzed using analysis of variance. Resistance or susceptibility status was assigned with Canto-Saenz host designation scheme. There was variability in the growth of the tree seedlings. Simphonia africana had the highest GI, Pf and RF of 3.3, 54,500 and 22.07, respectively and these values were significantly higher than values from other seedlings. Six tree seedlings; Simphonia africana, Theobroma cacao, Gmelina arborea, Piptadeniastrum africana, Chrysophyluum albidium and Parkia biglobosa were found to be susceptible to M. incognita, while six (Tetrapleura tetraptera, Anacardium occidentale, Annonas muricata, Dinium guinensis and Vitex doniana) were found to be resistant and three (Treculia africana, Mangifera indica and Dacryodes edulis) were tolerant. Resistant tree seedlings should be planted in M. incognita-infested plantation and susceptible species should be treated even in

Published: June 2021

Background: Patients with active cancer are considered to be a high-risk group during the COVID- 19 pandemic. Reports of studies on the impact of COVID-19 infection on cancer patients in Bangladesh are sparse. This study was conducted to describe the clinical presentation and assess the outcome of COVID-19 infected cancer patients.
Methods: In this prospective study, we enrolled 43 patients with active cancer from different cancer hospitals in Dhaka, Bangladesh who were tested positive for RTPCR of COVID-19. The study period was from August to October 2020 (three months) following ethical approval and informed written consent was ensured. The data were collected in a structured questionnaire form by interviewing the patients/relatives and from medical records of inpatient and outpatient departments and analyzed by SPSS version 25.
Results: The mean age of the 43 study participants was 49.2 (±13.6) years with a male predominance (60.5%). The common primary malignancies were leukaemia (27.9%), carcinoma of the colon (18.6%), and carcinoma of the breast (14%). Diabetes (30.2%) and hypertension (27.9%) were the common co-morbidities. The most frequently found symptoms were fever and cough 67.4% each. Severe and critical illness were found in 27.9% and 2.3% cases respectively. 35 (81%) patients survived from COVID-19 and death was observed in 8 (19%) patients.There was no significant association of age, gender, primary malignancy type, and major co-morbidities with the outcome. Severe and critical illness were found to be significantly associated with higher mortality.
Conclusions: COVID-19 related mortality is higher in cancer patients than in the general population. Mortality depends on the severity of COVID-19 in these patients, associated with severe & critical cases.

Published: June 2021

Background and aims: Acute pancreatitis is the most common major post-ERCP complication ranging as high as 10% to 40%. Rectal NSAIDS (Indomethacin or Diclofenac) seem to be the most promising drugs to prevent post ERCP pancreatitis. We performed a trial to investigate the efficacy of indomethacin or diclofenac.
Methods: A prospective randomized comparative trial was performed at Dhaka from January 2013 to June 2019. Patients undergoing ERCP were randomly selected to group-A and group-B. Diclofenac 50mg suppository was given to group-A patients and Indomethacin 100mg suppository was given to group-B patients during or just after ERCP. The primary outcome was acute pancreatitis following the procedure which was defined by new upper abdominal pain, elevation of pancreatic lipase to at least 3 times the upper limit of normal level 24 hours after ERCP and hospitalization for 02 nights. Retrospective analysis of data of 122 patients who had undergone ERCP in 2012 but had no history of rectal NSAIDS (group C) was done.
Results: Total 613 patients were included in this study and followed up. Post ERCP pancreatitis developed in 21(8.5%) patients of group-A (n=247), in 19(7.78%) patients of group-B (n=244) and in 20(17.85%) patients of group-C (n=122)(p=0.02). Moderate to severe pancreatitis was found in 08(3.23%) patients of group-A, in 06(2.45%) patients of group-B and in 12(9.83%) patients of group-C(p= 0.01). Administration of these NSAIDS showed clear benefit to reduce occurrence of Post ERCP pancreatitis when compared with no drug group (P=0.01). The efficacy of indomethacin compared with diclofenac was similar (P=0.874).
Conclusions: Prophylactic use of rectal indomethacin or diclofenac during or just after ERCP significantly reduces the incidence of post ERCP pancreatitis. These NSAIDs are inexpensive, safe and should be used routinely in each patient undergoing ERCP.

This study represents comprehensive taxonomic information on current floristic composition in the semi-natural campus area of Jahangirnagar University. This study reveals that this campus area harbours a total of 917 species belonging to 574 genera and 145 families of vascular plants. 70.34% of these species are wild and the rest are cultivated/planted. 63.79% of the species are native and 36.21% are exotic to Bangladesh. Pteridophytes and Gymnosperms are represented by 22 and 12 species, respectively, whereas, Angiosperms by 883 species. Magnoliopsida (dicotyledons) and Liliopsida (monocotyledons) are composed of 618 and 265 species, respectively. The family Poaceae with 89 species is the largest, which is followed by Fabaceae with 44 species and Asteraceae with 40 species. Most of the species are herbs (56.16%) and growing in diverse habitats. All species are economically or ecologically important, but mostly as medicinal, ornamental, fodder and forage, fruit, vegetable, timber and fuel wood. The study area houses 15 plant species, previously listed as threatened to Bangladesh. Thus, the study area is floristically rich in respect to its number of plant species belonging to different groups and its size. This area might serve as a campus-based excellent center of biodiversity conservation by strengthening the existing management and adopting necessary policies and strategies.

Published: June 2021

Random amplified polymorphic DNA (RAPD) markers were employed for characterization, assessment of genetic variation and inferring relationships among six variants of Canna indica L. A total of 198 RAPD bands ranging from 200 bp to 3 kbp were generated by all the six variants. Among them, most of the bands were found to be polymorphic, four band were unique of which two bands (OPA022000 and OPA043000) were observed in the variant 2 (small red) and the other two (OPA013000 and OPA053000) were noticed in the variant 4 (orange), and the remaining bands were found to be monomorphic. The pair-wise genetic distance was determined among the six variants that ranged from 0.1446 to 0.6554. A dendogram was constructed based on the RAPD profiling to infer the relationship among the six variants of C. indica that resulted in two major clusters: the first one contained two variants, viz. variant 1 (local red) and variant 2 (small red), while the second cluster composed of the remaining four variants. The results as revealed from the RAPD analysis were found congruent with those of morphological and anatomical investigation of the species.

Authors: Geethu V , Shamina Mamiyil 
Published: June 2021

Cyanobacteria are Gram negative, photosynthetic and nitrogen fixing microorganisms which contribute much to our present-day life as medicines, foods, biofuels and biofertilizers. Western Ghats are the hotspots of biodiversity with rich combination of microbial flora including cyanobacteria. Though cosmopolitan in distribution, their abundance in tropical forests are not fully exploited. To fill up this knowledge gap, the present research was carried out on the cyanobacterial flora of Peruvannamuzhi forest and Janaki forests of Western Ghats in Kozhikode District, North Kerala State, India. Extensive specimen collections were conducted during South-West monsoon (June to September) and North-East monsoon (October to December) in the year 2019. The highest diversity of cyanobacteria was found on rock surfaces. A total of 18 cyanobacterial taxa were identified. Among them filamentous heterocystous forms showed maximum diversity with 10 species followed by non- heterocystous forms with 8 species. The highest number of cyanobacteria were identified from Peruvannamuzhi forest with 15 taxa followed by Janaki forest with 3 taxa. The non- heterocystous cyanobacterial genus Oscillatoria Voucher ex Gomont showed maximum abundance with 4 species. In this study we reported Planktothrix planktonica (Elenkin) Agagnostidis & Komárek 1988, Oscillatoria euboeica Anagnostidis 2001 and Nostoc interbryum Sant’Anna et al. 2007 as three new records from India.

Published: June 2021

The Internal Transcribed Spacers (ITS) sequences of nuclear ribosomal DNA (nrDNA) are commonly used in plant molecular phylogenetics for the molecular based taxonomic identification and DNA barcoding because of shorter length and easy to amplify by using the universal primers, and further has discrimination ability to distinguish the taxon at lower taxonomic level. The present molecular phylogenetic analysis of ITS nrDNA sequences focuses to determine the taxonomic status of an unresolved medicinally important species Euphorbia schimperiana Scheele of the family Euphorbiaceae reported from Saudi Arabia. The combined length of the entire ITS region in E. schimperiana is 644 nucleotides. The study reveals that E. schimperiana shows a close proximity with the members of the subgenus Esula.

Published: June 2021

Indo-Birmanian is considered as the domesticated region and primary center of eggplant diversity from where it spread to other secondary centers of diversity. In this study, the genetic diversity among 56 eggplant genotypes from three secondary centers of diversity (Bangladesh, Malaysia and Thailand) was assessed using 11 morphological traits. The experiment was laid in a complete randomized block design with three replications. A wide significant variation was observed for all the morphological traits, and highly significant differences among the three centers of diversity. High heritability and genetic advance was found for different traits i.e. fruit length, fruit diameter, fruit girth, fruit length to width ratio, average fruit weight, number of fruits per plant, fruit yield per plant, plant height and number of primary branches per plant. The selected best traits i.e. number of fruits per plant, average fruit weight and fruit yield per plant showed high heritability along with high genetic advance and less environmental influence but the high value of PCV and GCV. So these traits could be useful for selection criteria in the future breeding program. These results are relevant for evolutionary studies, breeding programs, and management of eggplant genetic resources.

Climate change, biosystematics and taxonomy
Authors: Alam M Khairul 
Published: June 2021

The history of biosystematics research and its impacts on climate goes before political ramifications. Climate change is altering the environments and likely to result in changes in the distribution of species, flowering times; migrate and adapt to the new environmental conditions; or extinction. Adaptive capacity is the ability of the plants to adapt to the impacts of climate change. Adaptation process is going in nature through phenotypic plasticity, natural selection or migration or polyploidization. The options are not mutually exclusive. Phenotypic plasticity may be the most efficient way of adaptation to a new environment. Polyploidization may increase tolerance to diverse ecological conditions and the high incidence of polyploidy in plants indicates its adaptive significance. Population having polyploid pillar complex is a good backup support towards microevolution and speciation, a mode of adaptation. The paper discusses about these biosystematics approaches towards adaptation to new environmental conditions resulting from climate change. It also discusses about the role of taxonomists under the changed circumstances. It is evident from the review that a set of biosystematics data along with other ecological and conservation information needs to be included in Flora and Monographs. It reveals that it was as far as worked out at the Paris Botanical Congress 1954 and put up by Stebbins in a series of proposals, termed as “Stebbins’ Ten Points” that needs further enrichment.

Objetivo: analisar o comportamento da letalidade e mortalidade e o perfil de desenvolvimento da COVID-19 nos estados de maior risco de adoecimento até 15 de março de 2021. Metodologia: Estudo descritivo, retrospectivo e analítico dos dados epidemiológicos dos estados da faixa vermelha de risco de adoecimento até a data de 15 de março de 2021. Na análise, priorizou-se 04 municípios com maior incidência em cada estado. Resultados e Discussão: Maior contribuição de casos confirmados observado na região Sudeste, Nordeste, Centro Oeste e Norte, respectivamente. Dos 13 estados, 07 deles em apenas 04 municípios contribuíram com mais de 40% de casos confirmados. As taxas de mortalidade variaram de 0,07 (Maranhão) a 1,08 (Pará) e as taxas de letalidade entre os estados variaram de 1,34 (Amapá e Tocantins) e 2,90 (São Paulo). Nos estados com maior concentração de casos confirmados em menor número de municípios, existe a possibilidade de bloqueio da doença, através de ações especificas, enquanto nos estados em que disseminação do vírus é observada em vários municípios, a tendência de descontrole é evidente. Conclusão: Estratégias de controle sugeridas: educação para a saúde; uso de máscara obrigatória, participação dos educadores do ensino público e privado na educação sanitária junto ás famílias de seus alunos; barreiras sanitárias nas rodovias dos municípios que juntos estejam acima de 40% de casos confirmados, uso da inteligência local em saúde, que combina o rastreamento de contatos e testes rápidos para mitigar surtos de COVID-19, por todos os gestores das três esferas de governo e avaliações periódicas do quadro epidemiológico, para que as estratégias implementadas continuem ou sejam aperfeiçoadas.
