APPLICATION OF MOBILE PHONE-BASED PORTABLE MICROSCOPY IN CLINICAL HISTOPATHOLOGY: A FEASIBILITY STUDY

Objectives: To check the feasibility of using mobile phone-based microscopy for various types of human histopathological sample investigations. Methodology: A feasibility study was performed by imaging several histopathological samples with one novel type of microscope "Foldscope" and image compared with a conventional microscope in the laboratory facility. The image acquired from both sources were edited further and put together for comparison. Results: Mobile phone- based microscope acquired images were observed and compared with a conventional microscope and found morphology of the tissue sections were significantly similar as of conventional light microscope images. Conclusion: By comparing the image of some non-human histopathological sample, it could be stated that this method is also feasible for human histopathological sample investigations, especially in the low resource area or in case of emergency situations.

FEASIBILITY STUDY ON BLOOD CELL COUNTING USING MOBILE PHONE-BASED PORTABLE MICROSCOPE

Objectives: To check the feasibility of using the mobile phone-based microscope for blood cell counting from human blood histological sample. Methodology: A feasibility study was performed by imaging blood histology samples with one novel type of microscope "Foldscope" and image compared with a conventional microscope in the laboratory facility. The image acquired from both modalities were processed further and compared and analyzed. Results: Mobile phone-based microscope acquired images were observed and compared with a conventional microscope and found the blood cell counting feasibility and morphology analysis of the blood histology sample were significantly similar as of conventional light microscope images. Conclusion: By comparing the image from both microscopes, it could be stated that this method is feasible for human blood histopathological sample investigations like blood cell counting and morphology analysis especially in the low resource area or in case of any emergency situations

The royal food of termites shows king and queen specificity

シロアリの王と女王の特別食を世界初解明 --王と女王の繁殖と長寿を支えるロイヤルフード--. 京都大学プレスリリース. 2023-07-13.Society in eusocial insects is based on the reproductive division of labor, with a small number of reproductive individuals supported by a large number of non-reproductive individuals. Because inclusive fitness of all colony members depends on the survival and fertility of reproductive members, sterile members provide royals with special treatment. Here we show that termite kings and queens each receive special food of a different composition from workers. Sequential analysis of feeding processes demonstrated that workers exhibit discriminative trophallaxis, indicating their decision-making capacity in allocating food to the kings and queens. LC-MS/MS analyses of the stomodeal food and midgut contents revealed king- and queen-specific compounds including diacylglycerols and short-chain peptides. DESI-MSI analyses of ¹³C-labelled termites identified phosphatidylinositol and acetyl-L-carnitine in the royal food. Comparison of the digestive tract structure showed remarkable differences in the volume ratio of the midgut-to-hindgut among castes, indicating that digestive division of labor underlies reproductive division of labor. Our demonstration of king- and queen-specific food in termites provides insight into the nutritional system that underpins the extraordinary reproduction and longevity of royals in eusocial insects

Factors Influencing the Usage of Broadband for the Youth and Adolescent in Bangladesh: A Cross-Sectional Study

Purpose: This study aimed at examining the adoption factors of broadband internet and exploring the factors which make difference between service providers. Approach/Methodology/Design: Purposive sampling was employed to select the sample. To collect data from social media users, a close-ended Google Form questionnaire was administered through social networking sites and 376 responses were obtained. The data was analyzed using partial least squares structural equation modeling (PLS-SEM, 3.1). Model estimation was performed with r2, Q2, and the effect size f2 that describes the path effect from exogenous construct to endogenous construct. Findings: This study revealed that the participants, despite having the barriers, were reasonably satisfied at different levels and it was a major motivation in the use of broadband. The use of broadband internet has not yet been improved substantially in Bangladesh due to the minimal internet speed, lack of decent standard of quality, and high maintenance cost. However, the study revealed that customer or user satisfaction created a huge positive impact on value creation. It was also statistically significant supporting the hypothesis of the study. Practical Implications: The results of the study provide the broadband companies with an idea about broadband preference, assisting them in analyzing the variables closely to get more loyal customers. Originality/value: The study revealed that the degree of total frustration is below ten per cent, even though the severe challenge is considered very small. The study also showed that most of the participants were reasonably satisfied at different levels and it was a major motivation in the use of broadband
