Selection of high yielding and stable maize hybrid requires effective method of evaluation. Multienvironment evaluation is a critical step in plant breeding programs that is aimed at selecting the ideal genotype in a wide range of environments. A method of evaluation that combines a variety parameter of stability could provide more accurate information to select the ideal genotype. The aims of the study were (i) to identify the effect of genotype, environment, and genotype × environment interactions (GEIs) on maize hybrid yields and (ii) to select and to compare maize hybrids that have high and stable yields in diverse environments in Sumatra Island based on combined analysis, selection index, and GGE biplot. The study was conducted in five different environments in Sumatra Island, Indonesia, using a randomized complete block design repeated three times. Data were estimated using combined variance analysis, parametric and nonparametric stability, sustainability index, and GGE biplot. The results showed that the genotype had a significant effect on maize hybrid yields with a contribution of 41.797%. The environment contributed to 24.314%, and GEIs contributed 33.889% of the total variation. E1 (Karo, South Sumatra; dry season) and E3 (Tanjung Bintang, Lampung; dry season) were identified as the most ideal environments (representative) for testing the hybrids for wider adaptability. The maize hybrid with high and stable yields can be selected based on combined stability analysis and sustainability index as well as GGE biplot. These three methods are effectively selected high yielding and stable genotypes when they are used together. The three maize hybrids, namely, MH2, MH8, and MH9, are recommended as high yielding and stable genotype candidates.

Aim: Although many pain assessment tools exist, none are specific to the relatively unique presentation of pulpal pain. The aim of this study was to develop and validate a novel pain assessment tool based on pulp symptoms.
Methodology: A preliminary list of items best-describing pulpitis was developed based on deductive and inductive approaches and the preliminary tool was piloted (n = 80).

Objective: This study aims to evaluate our experience in the diagnosis of hereditary ataxias (HAs), to analyze data from a real-world scenario.
Study Design: This is a retrospective, cross-sectional, descriptive study conducted at a single Italian adult neurogenetic outpatient clinic, in 147 patients affected by ataxia with a suspicion of hereditary forms, recruited from November 1999 to February 2024. A stepwise approach for molecular diagnostics was applied: targeted gene panel (TP) next-generation sequencing (NGS) and/or clinical exome sequencing (CES) were performed in the case of inconclusive first-line genetic testing, such as short tandem repeat expansions (TREs) testing for most common spinocerebellar ataxias (SCA1-3, 6-8,12,17, DRPLA), other forms [Fragile X-associated tremor/ataxia syndrome (FXTAS), Friedreich ataxia (FRDA) and mitochondrial DNA-related ataxia, RFC1-related ataxia/CANVAS] or inconclusive phenotype-guided specific single gene sequencing.

Femtosecond lasers represent a novel tool for tattoo removal as sources that can be operated at high power, potentially leading to different removal pathways and products. Consequently, the potential toxicity of its application also needs to be evaluated. In this framework, we present a comparative study of Ti:Sapphire femtosecond laser irradiation, as a function of laser power and exposure time, on water dispersions of Pigment Green 7 (PG7) and the green tattoo ink Green Concentrate (GC), which contains PG7 as its coloring agent.

Introduction: As a result of increased incidence of anterior cruciate ligament (ACL) injury in young athletes, there is a rise in the indications surgical ACL reconstruction procedures. The value of anterolateral ligament (ALL) reconstruction emerges as a proposed solution to prevent graft failures and improve stability in this high demanding category of patients. The purpose of this study is to present our experience with a novel hamstring auto-grafting technique, the single antegrade sling graft (SASG), for combined reconstruction of both ACL and ALL using autologous gracilis (GR) and semitendinosus (ST) grafts utilizing a single femoral tunnel and double tibial tunnels.

The flextensional transducer (FT) is a typical low-frequency transmitting transducer that is capable of high-power operation due to its capacity for displacement amplification. This article uses the structural configuration of the class IV FT as the basis for designing a ring transducer, which is a circular structure comprising a multitude of class IV flextensional structures as well as circular acoustic radiation structures. The flextensional structure drives the circular acoustic radiation structure, which in turn generates sound waves at low frequencies.
