CD56 AS IMMUNOMARKERS IN THE DIAGNOSIS OF PAPILLARY THYROID CARCINOMA
No full textThyroid cancer is the most common malignant endocrine tumor. Nowadays tissue biopsy and pathological assessment are the best diagnostic modalities for thyroid lesions. Differential diagnosis between adenomas and follicular variant of papillary thyroid carcinoma (PTC) is an important issue in pathology. Papillary carcinoma typically stains for Thyroglobulin, TTF-1, Pan-Cytokeratin and PAX-8. An assortment of markers, such as Cytokeratin-19, HWCK, HBME-1, GAL-3, CD57, CITED-1, CD15, Fibronectin-1, CD44 and PDGF have been proposed to be of significance in the diagnosis of papillary carcinoma. Considering the above, the purpose of the study is to show CD56, a neural cell adhesion molecule can be used as immunomarkers in the diagnosis of PTC. Its expression may affect the migratory capability of tumor cells. Hence it is not surprising that loss of CD56 correlates with metastatic potentials and poor prognostic outcome in some malignancies. The thyroidectomy specimens of the 30 patients has been used and statistically analyzed in the present clinical case study. The results revealed the potential usage of CD56 expression in serving as immunomarkers in the diagnosis of papillary thyroid carcinoma
A STUDY OF NON-NEOPLASTIC HYPERPIGMENTED SKIN LESIONS
No full textThe organ forms an immune network. Through its pigments, it provides special defense against UV radiation. It is associated with the thermoregulation, retention and excretion of fluid. It has sensory functions and has an aesthetic role. Skin acts as a mirror of human being through which manifestations of systemic diseases can be envisioned. Melanin pigmentation occur in two ways as constitutive changes (genetically determined) and facultative changes (augmented by sun exposure). Ultraviolet (UV) irradiation regulates melanin production, as well as endocrine and autocrine factors. Ethnic differences in complexion are caused by the number, shape and distribution of melanosomes. As a result, the purpose of this prospective study was to determine the prevalence of non-neoplastic hyperpigmented skin lesions. Cysts and Group VI-tumors of the dermis and sub cutis belonged to this group. A thorough clinical history and examination are required for skin disorders, just as they are for other organ systems. In these circumstances, the histological findings should be contrasted clinically, resulting in a reasonable diagnosis and treatment. The documentation of the breadth of skin lesions\u27 dissemination has been critical to our understanding of etiopathogenesis
Fibrous Tumor of the Breast: Case Report of an Underrecognized Entity
No full textFibrous tumor of the breast is an underappreciated, distinctive, benign, nonrecurrent lesion of the breast. The cytological features of this condition are not well characterized. We present a case report of a 30-year-old female presenting with a hard mass in her right breast. Fine needle aspiration showed smears of low cellularity showing a few clusters and sheets of mostly uniform benign epithelial cells, some of which were lined by myoepithelial cells. Scattered bipolar bare nuclei or stromal fragments were not seen. Excision with subsequent histopathological examination revealed a well-circumscribed, heavily collagenous tumor with atrophy and replacement of the epithelial and ductal elements of the breast, and diagnosed as fibrous tumor. Being nonrecurrent, it is important to distinguish this lesion from fibromatosis of the breast.</jats:p
Stock status and spawning potential ratio of orange mud crab (Scylla olivacea, Herbst 1796) in the southwestern coastal waters of Bangladesh
No full textScylla olivacea (Orange mud crab) is a second commercial invertebrate species exported from Bangladesh. Though a significant portion of exports are supported by aquaculture, their farming ultimately depends on their wild stocks. Unfortunately, unregulated exploitation has led to a significant decline in the natural biomass of this species, raising concerns about the sustainability of crab production in Bangladesh. The study aimed to assess the stock status of S. olivacea (Orange mud crab) from the Southwestern coastal water of Bangladesh. One-year length frequency (width frequency-WF for crustacean fishery) data were collected and analyzed using the LBB (Length-based Bayesian Biomass) and LB-SPR (Length-based spawning potential ratio) methods. The assessed width parameter depicted the exploitation of small-size individuals (Wc=< Wc_opt) of S. olivacea. The estimated B/B0 (0.25) suggests that 75 % of the wild stock had already been harvested, and biomass cannot produce MSY. The mean estimates for SW50 % and SW95 % were 8.29 cm and 12.76 cm respectively, revealing the use of a small mesh-size net for crab harvesting. The assessed Spawning Potential Ratio (SPR) was 12 % which is below the SPR limit reference point (SRP) of 20 %. This research confirmed the overfished (F/M = 1.4) and overexploited (E = 0.58) status of S. olivacea in Bangladesh. To ensure the sustainability of coastal fisheries in Bangladesh, the authorities must take immediate management measures to control the overexploitation of this species
Fisheries Reference Point and Stock Status of Croaker Fishery (Sciaenidae) Exploited from the Bay of Bengal, Bangladesh
No full textThis research evaluated fisheries reference points and stock status to assess the sustainability of the croaker fishery (Sciaenidae) from the Bay of Bengal (BoB), Bangladesh. Sixteen years (2001–2016) of catch-effort data were analyzed using two surplus production models (Schaefer and Fox), the Monte Carlo method (CMSY) and the Bayesian state-space Schaefer surplus production model (BSM) method. This research applies a Stock–Production Model Incorporating Covariates (ASPIC) software package to run the Schaefer and Fox model. The maximum sustainable yield (MSY) produced by all models ranged from 33,900 to 35,900 metric tons (mt), which is very close to last year’s catch (33,768 mt in 2016). The estimated B > BMSY and F MSY indicated the safe biomass and fishing status. The calculated F/FMSY was 0.89, 0.87, and 0.81, and B/BMSY was 1.05, 1.07, and 1.14 for Fox, Schaefer, and BSM, respectively, indicating the fully exploited status of croaker stock in the BoB, Bangladesh. The representation of the Kobe phase plot suggested that the exploitation of croaker stock started from the yellow (unsustainable) quadrant in 2001 and gradually moved to the green (sustainable) quadrant in 2016 because of the reduction in fishing efforts and safe fishing pressure after 2012. Thus, this research suggests that the current fishing pressure needs to be maintained so that the yearly catch does not exceed the MSY limit of croaker. Additionally, specific management measures should implement to guarantee croaker and other fisheries from the BoB
Stock Assessment of Exploited Sardine Populations from Northeastern Bay of Bengal Water, Bangladesh Using the Length-Based Bayesian Biomass (LBB) Method
No full textStock assessment is necessary to understand the status of fishery stocks. However, for the data-poor fishery, it is very challenging to assess the stock status. The length-based Bayesian biomass (LBB) technique is one of the most powerful methods to assess the data-poor fisheries resources that need simple length frequency (LF) data. Addressing the present gap, this study aimed to assess the stock status of three sardines (Sardinella fimbriata, Dussumieria acuta, and D. elopsoides) in the Bay of Bengal (BoB), Bangladesh using the LBB method. The estimated relative biomass for S. fimbriata was B/B-0 B-MSY/B-0 for D. acuta and D. elopsoides indicates healthy biomass. Additionally, for S. fimbriata, the length at first landing was smaller than the optimum length at first landing (Lc L-c_opt). Therefore, increasing the mesh size of fishing gears may help to ensure the long-term viability of sardine populations in the BoB, Bangladesh.Peer reviewe
Length-weight relationships and condition factors of mono- and mixed-sex Nile tilapia (Oreochromis niloticus) in open water cage culture system
No full textThe current study compared the length-weight relationships and condition factors in mono- and mixed-sex Nile tilapia (Oreochromis niloticus). The trial lasted for 91 days and included two treatments with five replications for each, all with the same stocking density. During the study period, 20 randomly selected fish individuals were measured and recorded from each cage every two weeks. The observed growth trend was allometric, with no significant difference in the mean exponential values (b), 2.696 and 2.65 for mono and mixed-sex tilapia respectively. There was a significant difference in final weight gain between monosex (171.58±7.39 g) and mixed-sex (149.09±4.14 g) tilapia. There was no significant difference in final length between monosex (19.80±0.42 cm) and mixed-sex (19.80±0.42 cm) tilapia. Moreover, the mean correlation coefficient (r2) of both groups was positive. The Fulton condition factor (K) also varies from 0.700 to 1.000 (monosex) and 1.000 to 1.010 (mixed-sex). The relative condition factor (Kn) for monosex and mixed-sex tilapia ranged from 1.96 to 2.222 and 2.092 to 2.35 respectively, indicated good aquaculture conditions. The present findings will attract fish farmers to mixed-sex tilapia culture by allowing them to lessen hormone administration and expected to boost national fish production through open water cage aquaculture
Estimating Stock Status and Biological Reference Points of the Sardine Fishery Using the Surplus Production Model from the Bay of Bengal, Bangladesh
No full textThis research examined the biological reference points (BRPs) and stock status of the sardine fishery in the Bay of Bengal (BoB), Bangladesh, to determine the sustainability of this resource. The Monte Carlo method (CMSY), the Bayesian state-space Schaefer surplus production model (BSM), and the ASPIC (a Stock Production Model Incorporating Covariates) software suite, were used to analyze catch–effort data obtained from the Yearbook of Fisheries Statistics of Bangladesh. All models derived maximum sustainable yields (MSY) ranging from 37,900 to 41,280 t, which is quite near to the catch from the latest year (38,051 t in 2020), indicating the fully exploited status of sardines. The estimated B < BMSY and F > FMSY values from the BSM and Schaefer models indicate a poor biomass and an unsafe fishing status. For Schaefer and BSM, the calculated F/FMSY values were 1.07 and 1.06, and the B/BMSY values were 0.92 and 0.75, which also indicate the overexploited status of the sardine fishery in the BoB, Bangladesh. This information will aid in developing management strategies and conservation policies for the sustainability and rebuilding of this commercially important resource in the BoB on the Bangladesh coast
Analyzing socio-economic drivers and their influence on overfishing practices in the Sundarbans mangrove fisheries ecosystem
No full textAbstract The Sundarbans is a crucial fishing ground in Bangladesh, provide abundant fisheries resources but face significant risks of overfishing. This study aims to identify the socioeconomic factors contributing to overfishing and explore the challenges faced by local fishing communities, ultimately recommending strategies for sustainability and environmental conservation. The research employed a comprehensive, multimethod approach to investigate the socioeconomic factors contributing to overfishing in the Sundarbans, drawing on insights from both primary data and secondary sources. The findings revealed that 64% of the fishers reported a notable decline in fish catch and income, which was attributed to characteristics of Malthusian overfishing. The study revealed the widespread use of destructive fishing practices, with 33.6% of fishers used both gill nets and Estuarine Set Bag Net (ESBN) nets, over 17% used chemicals and 16.6% creating a dam in the channels. Moreover, 58% of fishers reported the fish stock depletion. Women contributed to fishing, but economic hardships and natural calamities caused significant losses. Challenges to fish conservation efforts stem from inadequate education, ineffective management strategies, poor governance, and insufficient monitoring of regulations, leading to ongoing declines in fisheries resources. To prevent further depletion of the Sundarbans' mangrove fisheries, it is essential to strengthen regulatory monitoring and enforcement while increasing support for alternative livelihoods. The study suggests that global cooperation that can provide resources and expertise for sustainable practices. Additionally, investing in disaster resilience and poverty alleviation will reduce reliance on unsustainable fishing, protecting both the ecosystem and local communities
