AI Article Synopsis
- The study compared time-of-flight secondary ion mass spectrometry (ToF-SIMS) with the microbiopsy technique to measure enamel fluoride uptake (EFU).
- Enamel specimens were treated with various types of fluoride: sodium fluoride (NaF), stannous fluoride (SnF2), and amine fluoride (AmF), with AmF showing the highest EFU.
- Both methods provided highly correlating results (r = 0.95), suggesting that ToF-SIMS could be a reliable alternative for evaluating near-surface enamel fluoride uptake.
Article Abstract
This study evaluated the suitability of time-of-flight secondary ion mass spectrometry (ToF-SIMS) to assess enamel fluoride uptake (EFU) in comparison with the microbiopsy technique. Enamel specimens were exposed to equimolar solutions of fluoride prepared from sodium fluoride (NaF), stannous fluoride (SnF2), or amine fluoride (AmF). EFU was quantified by both techniques on the same specimens. EFU was found to be highest for samples treated with AmF, followed by SnF2 and NaF. Both methods yielded clearly interpretable, highly correlating (r = 0.95) data. ToF-SIMS can be considered a promising alternative to the microbiopsy technique for near-surface EFU assessment.

Objective: To assess the feasibility of first polar body transfer (PB1T) combined with preimplantation mitochondrial genetic testing for blocking the transmission of a pathogenic mitochondrial DNA 8993T>G mutation.
Methods: A Chinese family affected with Leigh syndrome which had attended the Reproductive Medicine Centre of the First Affiliated Hospital of Anhui Medical University in September 2021 was selected as the study subject. Controlled ovarian hyperstimulation was carried out for the proband after completing the detection of the mitochondrial DNA 8993T>G mutation load among the pedigree members.

Tuberculosis (TB) caused 1.5 million deaths in 2020, making it the leading infectious killer after COVID-19. Bacille Calmette-Guerin (BCG) is the only licensed vaccine against TB but has sub-optimal efficacy against pulmonary TB and reduced effectiveness in regions close to the equator with high burden.

Article Synopsis
- - The study explores the use of equine platelet lysate (ePL) as a replacement for fetal bovine serum (FBS) in growing muscle-derived mesenchymal stromal cells (mdMSCs) for regenerative medicine, addressing ethical and practical issues associated with FBS.
- - Two innovative 2D and 3D culture models were tested, with the 3D model yielding a higher total cell count than the 2D model, while both models confirmed the multipotent capabilities of mdMSCs through differentiation assays.
- - The mdMSCs showed promising immunomodulatory properties, significantly inhibiting myeloperoxidase (MPO) and reactive oxygen species (ROS) activity, especially in the
Histological analysis of the medial gastrocnemius muscle in young healthy children.

Histological data on muscle fiber size and proportion in (very) young typically developing (TD) children is not well documented and data on capillarization and satellite cell content are also lacking. This study investigated the microscopic properties of the medial gastrocnemius muscle in growing TD children, grouped according to age and gender to provide normal reference values in healthy children. Microbiopsies of the medial gastrocnemius (MG) muscle were collected in 46 TD boys and girls aged 2-10 years subdivided into 4 age groups (2-4, 4-6, 6-8 and 8-10 years).

Background: Diagnosis of cutaneous leishmaniasis (CL) usually relies on invasive samples, but it is unclear whether more patient-friendly tools are good alternatives for diverse lesions when used with polymerase chain reaction (PCR).
Methods: Patients with suspected CL were enrolled consecutively in a prospective diagnostic accuracy study. We compared dental broach, tape disc, and microbiopsy samples with PCR as index tests, using PCR with skin slit samples as reference test.
