Unstable slow oscillations couple with epileptogenic fast‐rhythm bistability in sleep‐related epilepsy: A stereoelectroencephalographic study

Epilepsia, Volume 67, Issue 6, Page 2924-2939, June 2026.
We examined the functional relationship between large‐scale δ‐band phase synchrony and local epileptogenic β–γ‐band amplitude bistability during NREM sleep. Increased synchrony and strong bistability characterized the epileptogenic zone, with strongest effects during N2 sleep, when seizures most frequently occur.

Baseline Data on Viral Suppression, Treatment Adherence and Mental Health in Peripartum Girls and Young Women With HIV in Zimbabwe

Journal of the International AIDS Society, Volume 29, Issue S1, June 2026.
ABSTRACT Introduction Peripartum adolescent girls and young women (AGYW) with HIV have lower viral suppression compared to older women. But the recently introduced dolutegravir‐based regimens and psychosocial peer motivation may improve viral control.

Manufacturing polycrystalline pellets of natural quartz for applications in thermoluminescence dosimetry

Materials Research, 2012
This paper describes the manufacturing process of quartz-pellets and shows their potential use as thermoluminescence dosimeters (TLD) for those applications where low-levels of ionising radiation are present.

A retrospective cohort study on the potential link between dolutegravir-based anti-retroviral therapy and weight gain compared to efavirenz-based anti-retroviral therapy in a tertiary care center in Jabalpur, Madhya Pradesh

National Journal of Physiology, Pharmacy and Pharmacology
Background: Anti-retroviral therapies (ARTs) for human immunodeficiency virus (HIV) such as dolutegravir (DTG) and efavirenz have been associated with weight gain.

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

Journal of Medical Radiation Sciences, Volume 73, Issue 2, Page 156-163, June 2026.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

Journal of Raman Spectroscopy, Volume 57, Issue 6, Page 1071-1080, June 2026.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.
