Implementation of a comprehensive program including psycho-social and treatment literacy activities to improve adherence to HIV care and treatment for a pediatric population in Kenya
BACKGROUND: To achieve good clinical outcomes with HAART, patient adherence to treatment and care is a key factor. Since the literature on how to care for pediatric HIV patients is limited, we describe here adherence interventions implemented in our comprehensive care program in a resource-limited setting in Kenya. METHODS: We based our program on factors reported to influence adherence to HIV care and treatment. We describe, in detail, our program with respect to how we adapted our clinical settings, implemented psycho-social support activities for children and their caregivers and developed treatment literacy for children and teenagers living with HIV/AIDS. RESULTS: This paper focused on the details of the program, with the treatment outcomes as secondary. However, our program appeared to have been effective; for 648 children under 15 years of age who were started on HAART, the Kaplan-Meier mortality survival estimate was 95.27% (95%CI 93.16-96.74) at 12 months after the time of initiation of HAART. CONCLUSION: Our model of pediatric HIV/AIDS care, focused on a child-centered approach with inclusion of caregivers and extended family, addressed the main factors influencing treatment adherence. It appeared to produce good results and is replicable in resource-limited settings
Automated quantitative analysis of shape features in human epithelial monolayers and spheroids generated from colorectal cancer cells
Book Title Intestinal Differentiated Cells Book Subtitle Methods and Protocols ISBN978-1-0716-3075-4 Chapter book Title Automated quantitative analysis of shape features in human epithelial monolayers and spheroids generated from colorectal cancer cells Description for the image named HCT116_Monolayer: HCT116 colorectal cancer cells have been grown as monolayers, then fixed and stained with Alexa 488-phalloidin to visualize actin filaments. Cells were imaged using a SP8 Leica confocal microscope. The image is the Sum projection of 3 independent planes (0.5 um each), exported to .tiff. The image serves as example for single cell analysis using automated packages such as Cellpose 2.0. Description for the image named HCT116_Spheroid: HCT116 colon cancer cells were seeded on low-attachment plates to generate spheroids. This image was acquired after 16h from seeding cells using a widefield Dmi8 Leica microscope. The image can be used to obtain automated cell contours and cell shape features from individual cells forming the spheroid using Cellpose 2.0 package and ImageJ/Fiji. A description of the steps to follow could be found in Brown and Juanes, 2023, ' Automated quantitative analysis of shape features in human epithelial monolayers and spheroids generated from colorectal cancer cells', a chapter in the "Intestinal Differentiated Cells" Book from the Methods in Molecular Biology - Springer Protocols from Nature Humana Press editorial
Structural modulation of π-conjugated linkers in D-π-A dyes based on Triphenylamine dicyanovinylene framework to explore the NLO properties
A donor-π-acceptor type series of Triphenylamine-dicyanovinylene based chromophores (DPMN1-DPMN11) was designed theoretically by the structural tailoring of π-linkers to exploit changes in the optical properties and their NLO behaviour. Density functional theory (DFT) computations were employed to understand the electronic structures, absorption spectra, charge transfer phenomena and the influence of these structural modifications on NLO properties. Interestingly, all investigated chromophores exhibited lower band gap (2.22-2.60 eV) with broad absorption spectra in the visible region, reflecting the remarkable NLO response. Furthermore, natural Bond Orbital (NBO) findings revealed a strong push-pull mechanism in DPMN1-DPMN11 as donor and π-conjugates exhibited positive, while all acceptors showed negative values. Examination of electronic transitions from donor to acceptor moieties via π-conjugated linkers revealed greater linear (=526.536-641.756 a.u) and non-linear (βtot =51313.8-314412.661 a.u) response. It was noted that the chromophores containing imidazole in 2nd p-linker expressed greater hyperpolarizability when compared with the ones containing pyrrole. This study reveals that by controlling the type of π-spacers, interesting metal-free NLO materials can be designed, which can be valuable for the hi-tech NLO applications

Supplementary Material from The impact of pelvic lateral rotation on hindlimb kinematics and stride length in the red-legged running frog, Kassina maculata
Some frog species, such as Kassina maculata (red-legged running frog), use an asynchronous walking/running gait as their primary locomotor mode. Prior comparative anatomy work has suggested that lateral rotation of the pelvis improves walking performance by increasing hindlimb stride length; however, this hypothesis has never been tested. Using non-invasive methods, experimental high-speed video data collected from eight animals were used to create two three-dimensional kinematic models. These models, each fixed to alternative local anatomical reference frames, were used to investigate the hypothesis that lateral rotation of the mobile ilio-sacral joint in the anuran pelvis plays a propulsive role in walking locomotion by increasing hindlimb stride length. All frogs used a walking gait (duty factor greater than 0.5) despite travelling over a range of speeds (0.04–0.23 m s−1). The hindlimb joint motions throughout a single stride were temporally synchronized with lateral rotation of the pelvis. The pelvis itself, on average, underwent an angular excursion of 12.71° (±4.39°) with respect to the body midline during lateral rotation. However, comparison between our two kinematic models demonstrated that lateral rotation of the pelvis only increases the cranio-caudal excursion of the hindlimb modestly. Thus, we propose that pelvic lateral rotation is not a stride length augmenting mechanism in K. maculata
