Background: Six thoracic pathologists reviewed 259 lung neuroendocrine tumours (LNETs) from the lungNENomics project, with 171 of them having associated survival data. This cohort presents a unique opportunity to assess the strengths and limitations of current World Health Organization (WHO) classification criteria and to evaluate the utility of emerging markers.

Patients And Methods: Patients were diagnosed based on the 2021 WHO criteria, with atypical carcinoids (ACs) defined by the presence of focal necrosis and/or 2-10 mitoses per 2 mm.

ICSI is one of the most commonly used techniques to treat infertility. The sperm selection for the procedure is done 'randomly' by the embryologist according to the motility and morphology parameters which is known not to reflect the potential of a sperm for fertilization, pregnancy and a healthy childbearing. Since the apoptosis rate is higher in sperm cells of infertile patients, it is more likely to choose an apoptotic sperm by the 'random selection method'.

Article Synopsis
  • - The study investigates the impact of chronic unpredictable stress (CUS) on the blood-testis barrier (BTB) and sperm quality in C57Bl/6 mice by comparing a stress group to a non-treated control group.
  • - Results showed that CUS led to increased oxidative stress markers, reduced testosterone levels, and damage to BTB integrity, as evidenced by histopathological evaluations and changes in key BTB proteins ZO-1 and CLDN11.
  • - Although total sperm concentration and motility remained unchanged, CUS significantly decreased progressive motility, sperm morphology, chromatin integrity, and acrosomal reaction rates, indicating that chronic stress negatively affects sperm quality.

Objective: This study aimed to investigate the effect of acidulated phosphate fluoride (APF) gel and casein phosphopeptide/amorphous calciumphosphate (CPP-ACP) on the dental erosion produced by carbonated soft drink in primary teeth.

Study Design: This study evaluated by an in vitro model the effect of APF gel and CPP-ACP on the dental enamel previously subjected to erosive challenge with carbonated soft drink.

Purpose: The present prospective, randomised, placebo-controlled, clinical trial was designed to evaluate the clinical effects of a commercially available dentifrice containing fluoride, xylitol or xylitol-probiotic on the decrease of plaque and gingival inflammation in children between 13 and 15 years of age.

Materials And Methods: Forty-eight adolescents were randomly grouped into three groups of n = 16 each: study group A received xylitol (Xyliwhite) toothpaste; study group B received xylitol-probiotic (Periobiotic) toothpaste; and the control group C received fluoride (Colgate Max Fresh) toothpaste. The subjects were instructed to use the dentifrice determined and a modified Bass brushing technique twice a day for two minutes over a 6-week perioed.

The presence of supernumerary teeth, also known as hyperdontia, is the condition of having teeth in addition to the regular number of teeth. The occurrence of multiple supernumerary teeth is often found in association with syndromes such as Gardner syndrome, Anderson-Fabry disease, Ellis-van Creveld syndrome, Ehlers-Danlos syndrome, incontinentia pigmenti, and Tricho-rhino-phalangeal syndrome. Only a few examples of nonsyndromic multiple supernumerary teeth have been reported in literature.

The aim of this study was to evaluate and compare the effects of two self-etch adhesive materials on the induction of oxidative stress and production of transforming growth factor-beta1 (TGF-beta1) and bone morphogenetic protein-2 (BMP-2) by cultured human gingival fibroblasts (HGF). Inflammation-free attached gingiva was obtained from healthy donors under informed consent. Following 24- and 72-h exposure of HGF to two different elutes of the test materials, cell viability was determined using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide (MTT) assay.
