Manual Hair Removal for Intraoral Flaps: a Simple Practice for Professional Education and Patient Cancer Care.

After resection of malignant tumors of the head and neck, reconstructions are commonly performed using surgical free flaps. In non-irradiated patients, hair may continue to grow at the reconstruction site after surgery, causing undesirable effects such as difficult to maintain oral hygiene, food and saliva accumulation, halitosis, dysphagia, moral distress, and impact on intimacy and sexuality. Until a standardized laser therapy protocol is available, manual depilation is an option that should not be underestimated to improve the patient's quality of life and available to every oral healthcare team.

Origin and evolution of the bread wheat D genome.

Bread wheat (Triticum aestivum) is a globally dominant crop and major source of calories and proteins for the human diet. Compared with its wild ancestors, modern bread wheat shows lower genetic diversity, caused by polyploidisation, domestication and breeding bottlenecks. Wild wheat relatives represent genetic reservoirs, and harbour diversity and beneficial alleles that have not been incorporated into bread wheat.

Evolution of Einkorn wheat centromeres is driven by the mutualistic interplay of two LTR retrotransposons.

Background: Centromere function is highly conserved across eukaryotes, but the underlying centromeric DNA sequences vary dramatically between species. Centromeres often contain a high proportion of repetitive DNA, such as tandem repeats and/or transposable elements (TEs). Einkorn wheat centromeres lack tandem repeat arrays and are instead composed mostly of the two long terminal repeat (LTR) retrotransposon families RLG_Cereba and RLG_Quinta which specifically insert in centromeres.

Death following cylindrical battery ingestion associated with toxic manganese levels.

Cases of battery ingestion are well documented in the scientific literature, especially concerning button cell battery ingestion in children. In this instance, the authors present an atypical case of a young man who voluntarily ingested a cylindrical alkaline battery containing manganese. The patient died approximately a week later, despite not exhibiting any specific symptoms.

Revisiting mandibular symphyseal shape in juvenile early hominins and modern humans using a deformation-based approach.

The juvenile mandible is important in the investigation of ontogenetic and evolutionary changes among early hominins. We revisit the mandibular symphysis in juvenile specimens of Australopithecus africanus and Paranthropus robustus with two main contributions. First, we employ, for the first time, methods of computational anatomy to model complex symphyseal shape differences.

The dental microscope in endodontic education: A feasibility study of a distance learning course.

This study aimed to evaluate the feasibility of preclinical training, specifically in root canal preparation, using a virtual educational system equipped with an operating microscope. Ten postgraduate general dentistry trainees and practitioners undergoing postgraduate training in endodontics participated. The telesimulation course included three steps: theory, demonstration of practical work by the teacher and lastly practical training by the participants.

Ancient chicken remains reveal the origins of virulence in Marek's disease virus.

The pronounced growth in livestock populations since the 1950s has altered the epidemiological and evolutionary trajectory of their associated pathogens. For example, Marek's disease virus (MDV), which causes lymphoid tumors in chickens, has experienced a marked increase in virulence over the past century. Today, MDV infections kill >90% of unvaccinated birds, and controlling it costs more than US$1 billion annually.

Mass animal sacrifice at casas del Turuñuelo (Guareña, Spain): A unique Tartessian (Iron Age) site in the southwest of the Iberian Peninsula.

Zooarchaeological analyses of the skeletal remains of 52 animals unearthed in the courtyard of an Iron Age Tartessian building known as Casas del Turuñuelo (Badajoz, Spain) shed light on a massive sacrifice forming part of a series of rituals linked to the site's last period of activity and final abandonment. The rites took place towards the end of the 5th century BCE when both the building (intentionally destroyed) and the sacrificed animals were intentionally buried under a tumulus 90 m in diameter and 6 m high. The main objective of the zooarchaeological and microstratigraphic analyses was to determine the phasing of the sacrificial depositions.

Therapeutic solutions for anterior restorations in disabled patients: Systematic review and case report.

Introduction: Treating anterior restorations is a real challenge for a dentist and conventional protocols are not always applicable. The aim of this study is to determine different therapeutic to conducting anterior restorations in disabled people.

Case Report: We begin by presenting the case of a 23-year-old, handicapped man, who was brought in consultation to compensate for the loss of the left upper central incisor (#21).

Refining the evolutionary tree of the horse Y chromosome.

The Y chromosome carries information about the demography of paternal lineages, and thus, can prove invaluable for retracing both the evolutionary trajectory of wild animals and the breeding history of domesticates. In horses, the Y chromosome shows a limited, but highly informative, sequence diversity, supporting the increasing breeding influence of Oriental lineages during the last 1500 years. Here, we augment the primary horse Y-phylogeny, which is currently mainly based on modern horse breeds of economic interest, with haplotypes (HT) segregating in remote horse populations around the world.

Comparison of muscle metabolomics between two Chinese horse breeds.

With their enormous muscle mass and athletic ability, horses are well-positioned as model organisms for understanding muscle metabolism. There are two different types of horse breeds-Guanzhong (GZ) horses, an athletic breed with a larger body height (~148.7 cm), and the Ningqiang pony (NQ) horses, a lower height breed generally used for ornamental purposes-both inhabited in the same region of China with obvious differences in muscle content.
