Ornamental aquarium organisms trade in Bangladesh
No full textThe study was conducted in Dhaka, Bangladesh, and was carried out for twelve (12) months from March 2018 to February 2019 with a view to represent the trading diagram of ornamental fish in Bangladesh. During the current study 270 varieties (230 freshwater, 36 marine, and 4 brackish water) belong to 149 species (109 freshwater 73%, 36 marines 24%, and 4 brackish water 3%) of 38 families under 10 orders and 6 crossbreeds’ varieties were recorded. Considering the number of species maximum 83 (55.70%) was found under the order Perciformes followed by Cypriniformes 24 (16.10%), Characiformes 18 (12.08%), Siluriformes 11 (7.38%), Osteoglossiformes 05 (3.35%), Atheriniformes 03 (2.01%), Lepisosteiformes 02 (1.34%), Polypteriformes 01 (0.6%), Myliobatiformes 01 (0.67%) and Cyprinodontiformes 01 (0.67%). The top five popular species were guppy (13.16%) followed by goldfish (12.39%), molly (8.54%), angelfish (6.23%), platy (5.93%). Most of the ornamental fish species were imported by importers from Thailand, Singapore, Indonesia, India, Malaysia, and Japan on the basis of demand. Then the imported shipment of aquarium fish and fish products was distributed among Dhaka Katabon fish shops, wholesalers, and retailers, according to their given order. After that, these were again distributed locally, to aquarium shops, breeders, ornamental fish farms all over the country. General customers and hobbyists purchase ornamental fish and aquarium products from local aquarium shops and businesses. The increasing tendency of the number of fish species was 5.96 times in the last 15 years and 3.31 times in the last 10 years. Local farms and aquarists’ breeders bred 76 varieties under 23 species due to its high demand and profitability. Pricing varied on varieties, species, size, and breeding status (local or abroad), availability and ranged from BDT 40.00-80,000.00 per pair. Considering the findings, aquarium fisheries is highly profitable at present and it will be a potential sector in Bangladesh. </p
Hysteria and its deceptive masks
No full textHysteria still exists, even if this stigmatizing term has been abandoned in favor of more descriptive terms (dissociative disorders, conversion disorders, functional disorders), and represents a frequent and disabling pathology. Even if in some situations, the establishment of a definitive diagnosis remains difficult, more and more clinical and paraclinical signs are developing to help in the diagnosis and the error rate is low. Thus, the clinician must currently make a positive diagnosis of conversion and no longer, as unfortunately often in the past, confine himself to evoking by default such a possibility in the face of an atypical picture accompanied by an extensive negative paraclinical assessment. The most probable etiology concerns triggering factors of a psychiatric nature (traumatic episode or psychic stress, vulnerability with a field of abuse in childhood, comorbidity of anxio-depressive disorders), which can, in turn, lead to changes in brain function, the exact neurobiological correlate of which remains to be determined, even if many leads have recently been suggested by brain imaging. The care of these patients requires an in-depth and specialized examination, if possible, with the help of a neurologist, then psychiatric care, combined with somatic follow-up. In the future, a better understanding of the etiological mechanisms will make it possible to develop more specific treatments.</p
Chronic (52-week) oral toxicity study of herbal tea of Moringa stenopetala and Mentha spicata leaves formulation in Wistar albino rats
No full textBackground: Moringa stenopetala leaves have long been used to treat diabetes, hypertension, respiratory problems, and other diseases. The herbal formulation of Moringa stenopetala and Mentha spicata leaves was found to be more effective in lowering high blood pressure and blood sugar levels. Unlike its pharmacological properties, the long-term safety profile of this herbal formulation has not been investigated yet. Thus, this study investigated the long-term (chronic) oral toxicity of herbal tea of M. stenopetala and M. spicata leaves blended in rats. Methods: Wistar albino rats were randomly distributed into four groups (n = 10/sex/group), and then randomly assigned to a control group and three test groups. The control group (G I) received distilled water. The test groups (G II-IV) received 559.36, 1118.72, and 2237.44 mg/kg of herbal tea of M. stenopetala and M. spicata leaves blend respectively, for 360 consecutive days. During the treatment period, in-life parameters (mortality, clinical symptoms, body weight, and food intake) were evaluated. On the 361st day, hematological, serum biochemical, gross morphological, and histological parameters were investigated.Results: Throughout the 360-day treatment period, no herbal tea-related deaths, severe clinical symptoms, loss of body weight, or food intake were seen in any of the treated groups. Bodyweight, food consumption, organ weight, hematological, and serum biochemical findings showed no significant differences between the control and treated groups in both sexes. Macro-pathological and histopathological examinations of the major organs (liver, kidney, heart, pancreas, stomach, and spleen) revealed no herbal tea-related pathologic alterations. Conclusion: The findings indicate that long-term (360-days) oral administration of the herbal tea of M. stenopetala and M. spicata leaves blend is well tolerated by rats. Hence, it would be safe/low toxic up to a dose of 2237.44 mg/kg/day in chronic exposure.</p
Bio-informatics approaches in liver disease: Incomplete without experimental validation
No full textIn the search for the treatment of hepatic diseases, multiple approaches have been used frequently such as bioinformatics and algorithm-based systems biology for the screening of already published data that leads to the identification of promising drug candidates at molecular levels. These studies provide a large data set of information and claim to identify many genes, which could be targeted for the cure. However, it is important to note that the identified compounds are only predictions and the potential of these suggested molecules or genes should be well confirmed by adopting robust and critical experimental approaches to satisfy all possible aspects to use them safely for therapeutic purposes. Therefore, I put forward the opinion that these predicted markers whether prognostic, diagnostic, or molecular must be evaluated critically through a well-defined experimental pipeline.</p
Relationship between gut microbiome and allergic asthma
No full textSince the late 20th century, environmental exposure to endotoxins has been very low and type I allergic disease has increased. In addition, we have increased exposure to PM2.5 and other chemicals. Recently, there is concern that the daily use of hygiene products containing antimicrobial substances is associated with an increased prevalence of allergies. It has been noted that these antimicrobial substances may exacerbate allergies. In our study, we confirmed that intratracheal administration of aqueous mite solution as an inhaled antigen and antimicrobial substance as an aggravating chemical induced much stronger allergic bronchial asthma in mice than in mice that received intratracheal mite solution alone. Thus, allergies have been found to be exacerbated by simultaneous exposure to both environmental antigens and man-made chemicals (adjuvants). Next, we analyzed 16S rRNA of the gut microbiota of triclosan-treated mice that developed an allergy. The bacterial gene abundance of 16S rRNA of Deltaproteobacteria, Erysipelotrichi and Clostridia was increased in a dose-dependent manner in triclosan-treated mice, while Bacteroides were decreased in these mice. The composition of the gut microbiota was altered after triclosan treatment and correlated with the exacerbation of asthmatic disease in these mice. In conclusion, because triclosan exacerbated the condition of allergic asthma in mice that inhaled mite antigens and were given triclosan to drink, and this condition was associated with an increase or decrease in certain bacteria in the gut, we suspect that if allergy sufferers continue to use triclosan, they will inhale dust mites and house dust on a daily basis, which may aggravate their allergy symptoms. Overall, the overuse of antimicrobials and preservatives in current daily life risks further increasing the number of allergic patients. The authors believe that it is time to rethink this lifestyle.</p
Importance of atomic physics in verification of experimental results and diagnostics of solar and astrophysical observations
Get PDFAccurate results are needed to confirm the experimental results of various atomic processes and analyze the solar and astrophysical observations of intensities of emission lines to infer plasma parameters like electron density, electron temperature and element abundance. A number of theories have been developed over the years to calculate phase shifts when electrons and positrons are scattered from targets. We discuss in this article the recent hybrid theory which has been applied to scattering processes, resonances and photoabsorption process, which is a bound-free transition.</p

Himotoki as a decision-making empowerment tool to live well with dementia
Get PDFShared decision-making is indispensable among people with dementia, their families, and healthcare professionals to ensure that people with dementia live well. Since living with dementia involves the process of losing one’s independence and requiring support from others in all aspects of life, everyday life becomes a series of shared decision-making and collaborative efforts. Dementia care includes the process of rebuilding relationships through shared decision-making and collaboration. In particular, it is of paramount importance to make decisions on how to live well with dementia. Owing to a decline in independence, it may become difficult for people with dementia to live well or achieve happiness on their own. Hence, they are expected to cooperate with people close to them, including family members, to lead happy and fulfilling lives. While making a shared decision, conversations with a person with dementia may result in miscommunication due to a decline in their ability to communicate. If it is difficult to understand certain words or actions of the person with dementia, rather than dismissing them as incomprehensible, caregivers are recommended to analyze the factors underlying those words and actions (background factors), such as the person’s current cognitive state and functioning, human and physical environments, and relationships with other people. </p

The small pelagic stocks in the area are exceptional wealth and as many opportunities in an international context, marked both by the scarcity of the resource and the need to make the sea c contribute more to food security and economic growth. The aim of this work is the study some features of S. pilchardus in the Moroccan waters.</p
Medical social workers’ and clinical psychologists’ understanding of autism spectrum disorders: A Nigerian Study
Get PDFIntroduction: Autism is a neurodevelopmental disorder characterised by difficulties in social communication and interaction, repetitive patterns of behaviour and focused interests and activities. Medical social workers and Clinical psychologists play vital roles in identifying and supporting autistic children with their families. They may help with therapy, rehabilitation, crisis interventions and outreach services. Adequate knowledge about Autism Spectrum Disorders (ASD) among Medical social workers and Clinical psychologists may enhance early recognition, diagnosis, appropriate referral and interventions that are known to improve prognosis in autistic children. This study determined Medical social workers’ and Clinical psychologists’ understanding of ASD.Materials and methods: Socio-demographic and Knowledge About Childhood Autism among Health Workers (KCAHW) questionnaires were administered to consenting 63 Medical social workers and 35 Clinical psychologists. Results: Sixty-three Medical Social workers and 35 Clinical psychologists participated in the study. The mean age of Medical social workers was 42.1 ± 8.6 years and 41.0 ± 8.9 years for Clinical psychologists (P = 0.525). Clinical psychologists who were males were 42.9% and 41.3% were male Medical social workers (P = 0.879). Medical social workers who have ever managed a child with autism in the course of their career were 42.9% while Clinical psychologists were 40.0% (P = 0.784). The mean knowledge score for variables in domain 1 for Clinical psychologists was 6.34 ± 1.78 while Medical social workers scored 5.40 ± 2.30 (P = 0.038). The score in domain 2 for Clinical psychologists was 0.91 ± 0.28 while Medical social workers scored 0.71 ± 0.46 (P = 0.009). The mean total score for Clinical psychologists was13.00 ± 2.86 whereas Medical social workers scored 11.51 ± 3.43 (P = 0.031).Conclusion: Clinical psychologists significantly scored higher than Medical social workers in knowledge mean scores in domains 1 and 2 and total mean scores. The scores of Clinical Psychologists though higher than scores by Medical social workers are still considered inadequate. It is recommended that the training curriculum of Medical social workers and Clinical psychologists should involve more tutorials, teachings and clinical rotations that would expose them to different aspects of ASD.</p
