Small auxin-up RNA (SAUR) proteins were known as a large family that supposedly participated in various biological processes in higher plant species. However, the SAUR family has been still not explored in cacao (Theobroma cacao L.), one of the most important industrial trees. The present work, as an in silico study, revealed comprehensive aspects of the structure, phylogeny, and expression of TcSAUR gene family in cacao. A total of 90 members of the TcSAUR gene family have been identified and annotated in the cacao genome. According to the physic-chemical features analysis, all TcSAUR proteins exhibited slightly similar characteristics. Phylogenetic analysis showed that these TcSAUR proteins could be categorized into seven distinct groups, with 10 sub-groups. Our results suggested that tandemly duplication events, segmental duplication events, and whole genome duplication events might be important in the growth of the TcSAUR gene family in cacao. By re-analyzing the available transcriptome databases, we found that a number of TcSAUR genes were exclusively expressed during the zygotic embryogenesis and somatic embryogenesis. Taken together, our study will be valuable to further functional characterizations of candidate TcSAUR genes for the genetic engineering of cacao., (© 2024. The Author(s).)

Background: Pilomatricoma is a common benign adnexal neoplasm in children. There are few epidemiological studies on this subject, with most relying solely on descriptive statistics., Methods: A cross-sectional study conducted in two tertiary hospitals in Mexico City from January 2017 to December 2023. Clinical and electronic records of patients with histopathological diagnosis of pilomatricoma, both sexes, under 18 years old, with any type of present comorbidity were selected. Records of patients with diagnosis not confirmed by histopathology or incomplete records were not included in the study., Results: Fifty-two cases with pilomatrixoma were included in the study, showing a total of 74 lesions. About 23.1% of the cases had multiple pilomatrixomas. 40.4% of the cases experienced pain; this symptom was associated with lesions > 15 mm in diameter and with multiple pilomatrixomas. Risk factors for lesions > 15 mm included age under 8 years, positive tent sign, tumor evolution longer than a year, and a non-classical clinical variety. The head and neck were the most commonly affected areas. The left upper extremity presented larger pilomatrixomas (median 18.5 mm) and occurred more frequently in adolescent patients (mean age 12.1 years) compared to other body areas., Conclusions: Pilomatrixoma in children shows clinical diversity, with specific findings based on size, number, and anatomical location., (Copyright: © 2024 Permanyer.)

Infantile hemangioma is a benign vascular tumor, the most common in childhood, whose natural evolution is the disappearance of the lesion in the pediatric age and which has effective and safe treatments that limit its growth and favor its disappearance at younger ages. Infantile hemangioma continues to be a reason for attention to complications, due to erroneous diagnoses, lack of knowledge of the condition, late referral or fear of the effects of the medications used for its treatment. Furthermore, its presence is normalized without taking into account that it can cause uncertainty, anxiety, feelings of guilt and, as a consequence, a significant impact on the quality of life, mainly in the parents or caregivers of the child. The need for a clinical practice guideline in our country arises from the high presentation of late-remitted complications in infantile hemangioma even with the availability of adequate treatments, the continuous evolution of medicine and the appearance of new evidence. Throughout the guide you will find recommendations regarding the diagnosis, treatment and follow-up of patients with infantile hemangioma, taking into account the paraclinical tests that can be performed, topical or systemic management options, as well as adjuvant therapies. For the first time, objective tools for patient follow-up are included in a guide for the management of infantile hemangioma, as well as to help the first contact doctor in timely referral., (Copyright: © 2024 Permanyer.)

Objectives: Genetic characteristics were investigated based on short tandem repeat (STR) data to assess the relationship between two Vietnamese Bouyei populations in Vietnam., Methods: We collected hair and buccal swab samples from two separate Bouyei populations in the mountainous region of Northern Vietnam, which are the Bo Y in Ha Giang Province and the Tu Di in Lao Cai Province. The study included data of 23 autosomal and 27 Y-chromosome STRs loci of 96 unrelated participants from a total Vietnamese Bouyei population of under 3300 individuals., Results: The results showed that these STR markers are valuable for differentiation of individuals and human genetic studies in Vietnamese Bouyei populations. Genetic analysis indicated that Tu Di and Bo Y people were from the same Bouyei population in China., Conclusions: The results supported the official historical records of the region and the classification of the Vietnamese government. Furthermore, the genetic data provided in this study will be helpful in investigating the genetic genealogy evolution and settlement or migration patterns of the Bouyei populations in Vietnam., (© 2021 Wiley Periodicals LLC.)

'Sugars Will Eventually be Exported Transporters' (SWEETs) are a group of sugar transporters that play crucial roles in various biological processes, particularly plant stress responses. However, no information is available yet for the CaSWEET family in chickpea. Here, we identified all putative CaSWEET members in chickpea, and obtained their major characteristics, including physicochemical patterns, chromosomal distribution, subcellular localization, gene organization, conserved motifs and three-dimensional protein structures. Subsequently, we explored available transcriptome data to compare spatiotemporal transcript abundance of CaSWEET genes in various major organs. Finally, we studied the changes in their transcript levels in leaves and/or roots following dehydration and exogenous abscisic acid treatments using RT-qPCR to obtain valuable information underlying their potential roles in chickpea responses to water-stress conditions. Our results provide the first insights into the characteristics of the CaSWEET family members and a foundation for further functional characterizations of selected candidate genes for genetic engineering of chickpea., (Copyright © 2022 Elsevier B.V.

Neonatal acne (NA) is a transitory dermatosis that occurs between the second and fourth weeks of life in 20% of children. This condition is more frequent in males, with a male-female ratio of 4.5:1. Present primary skin lesions are open and closed comedones which can evolve into papules, erythematous pustules and, in rare cases, nodules and cysts. NA topography includes the forehead, cheeks, chin, and eyelids, but occasionally it spreads to the scalp, neck, and trunk. NA occurs due to an elevated production of placental and neonatal androgens (of adrenal origin in both sexes and of testicular origin in males) which cause enlargement of the sebaceous glands and increases the production of sebum. Most cases are mild and transient, but if NA is severe and long-lasting, clinical and paraclinical examination will be necessary to find congenital adrenal hyperplasia or a virilizing tumor of adrenal or gonadal origin. The diagnosis of NA is clinical; its main differential -diagnoses are neonatal cephalic pustulosis, other neonatal vesiculopustular dermatoses, infectious diseases, and acneiform reactions. The resolution of NA is spontaneous. In most cases, the use of a mild dermal cleanser and water will be sufficient. For comedogenic lesions (open and closed comedones), topical retinoids or 20% azelaic acid may be used, as well as some topical antibiotics for inflammatory lesions., (Copyright: © 2021 Permanyer.)
