Abstract

An experiment was performed to observe the potentiality of synthetic hormone analogue in artificial propagation i.e., the embryonic and larval development of Heteropneustes fossilis. Broodfish were injected with S-GnRHa according to the following concentration: 1, 2.5 and 5 ml kg-1 of body weight (BW) to females and 0.5, 1.125 and 2.5 ml kg-1 BW to males, in treatment groups T1, T2 and T3, respectively each with three replicates. The fishes were ovulated at about 10-11 hours after the hormone injection. Result showed the highest fertilization (83.11±1.36) and hatching rate (89.56±1.04) in T2, whereas ovulation rate was 100% in all treatment groups. First cleavage was observed in 30 minutes of post-fertilization. Embryonic developmental period sequentially for 2-cell, 4-cell, 8-cell, 16-cell, 32-cell, 64-cell, Morula, Blastula, Gastrula, somatic formation, yolk-plug, twisting movement and pre-hatching were 00:30, 00:45, 01:10, 01:30, 02:00, 02:30, 03:00, 04:00, 06:40, 09:00-18:00, 19:00, 20:00-21:00 and 22:00 hours, respectively. Hatching occurred after 23:00 hours of fertilization. Finally, the current result suggested that S-GnRHa might be an effective synthetic hormone in artificial propagation of H. fossilis.

Abstract

Background: Bangladesh's healthcare system faces challenges in providing equitable access and quality healthcare to rural and remote communities compared to urban areas. To address these issues, the country has incorporated telemedicine into its healthcare system. Aims: This study aimed to assess the effectiveness of telemedicine services in rural Bangladesh. Methods: The study employed a mixed-method approach, including survey questionnaires and in-depth interviews. 100 participants were selected for the questionnaire survey for quantitative data, and 20 in-depth interviews were conducted to collect qualitative data. Results: The findings indicate that telemedicine has garnered a positive reception among rural residents. An overwhelming 86% regarded telemedicine as a cost-effective healthcare option. 44% reported accessing telemedicine services within 10 minutes, demonstrating their accessibility. Furthermore, a majority (54%) expressed satisfaction with telemedicine services. However, dissatisfaction was noted concerning the physical environment of the telemedicine centers. Conclusion: Overall, telemedicine in Bangladesh has proven effective in cost savings and time efficiency and has gained significant acceptance among rural residents. To further improve healthcare accessibility, expanding telemedicine centers to reach every remote union in Bangladesh is imperative. Additionally, raising awareness, providing ICT and telemedicine education, and ensuring affordable and reliable internet connectivity will maximize the potential of telemedicine services, ultimately benefiting underprivileged rural populations.
