Study Design: Face and content validation of a surgical simulation model.

Objective: Accidental transection of the inferior alveolar nerve (IAN) during bilateral sagittal split osteotomies (BSSO) has a reported incidence of up to 7%, determining important sensory disturbances in patients. Proper repair demands the need of microsurgical anastomosis skills.

Article Synopsis
  • The study focuses on developing a synthetic simulation model for training surgeons in endoscopic rectus sheath plication, an approach used for abdominal diastasis without skin excess.
  • Participants' skills were assessed through a questionnaire and their performance was evaluated by an expert observer using specific rating scales.
  • Results showed that the simulation model effectively differentiated between expert and non-expert surgeons, achieving validation according to the Messick framework, making it a useful tool for surgical training.

Article Synopsis
  • * Key genes studied include WNT16, FAM3C, ING3, CPED1, and TSPAN12, with strong evidence from mouse studies showing WNT16's essential role in maintaining bone mass and strength.
  • * Recent research in zebrafish reveals WNT16's dual role in shaping both bone and muscle, raising new questions about how its influence may affect BMD and fracture risk.

Background: The prognostic factors for tumor recurrence and mortality of patients diagnosed with Papillary Thyroid Carcinoma (PTC) with immediate surgery in Colombia has not been reported.

Objective: To retrospectively evaluate the risk factors for recurrence and survival at 10 years in patients with the diagnosis of PTC treated at Fundación Santa Fe deBogota (FSFB).

Methods: A total of 486 patients with thyroid surgery accompanied by medical follow-up were recruited.

Bone and muscle are coupled through developmental, mechanical, paracrine, and autocrine signals. Genetic variants at the CPED1-WNT16 locus are dually associated with bone- and muscle-related traits. While Wnt16 is necessary for bone mass and strength, this fails to explain pleiotropy at this locus.

Neurotrophins, such as nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and neurotrophin 3 (NT-3), NT-4, and NT-5, are proteins involved in several important functions of the central nervous system. The activation of the signaling pathways of these neurotrophins, or even by their immature form, pro-neurotrophins, starts with their recognition by cellular receptors, such as tropomyosin receptor kinase (Trk) and 75 kD NT receptors (p75NTR). The Trk receptor is considered to have a high affinity for attachment to specific neurotrophins, while the p75NTR receptor has less affinity for attachment with neurotrophins.

Exopolysaccharides (EPS) production is a characteristic that has been widely described for many lactic acid bacteria (LAB) of different genera and species, but little is known about the relationship between the functional properties of the producing bacteria and EPS synthesis. Although many studies were addressed towards the application of EPS-producing LAB in the manufacture of several dairy products (fermented milk, cheese) due to their interesting technological properties (increased hardness, water holding capacity, viscosity, etc.), there are not many reports about the functional properties of the EPS extract itself, especially for the genus Lactobacillus.

Under optimized conditions, the lactic acid bacterium Lactobacillus fermentum Lf2 secretes up to 2 gL of a mixture of polysaccharides into the fermentation medium when grown on sucrose. Earlier studies had shown that the mixture is biologically active and work was undertaken to characterise the polysaccharides. Preparative size exclusion chromatography was used to separate a high molecular mass β-glucan (weight average mass of 1.

Avian infectious laryngotracheitis (ILT) is a worldwide infectious disease that causes important economic losses in the poultry industry. Although it is known that ILT virus (ILTV) is present in Argentina, there is no information about the circulating strains. With the aim to characterize them, seven different genomic regions (thymidine kinase, glycoproteins D, G, B, C, and J, and infected cell polypeptide 4) were partially sequenced and compared between field samples.

Purpose: Depression is 3 times more prevalent in the cardiac than the general population in high-income countries and is particularly high in middle-income countries. Comorbid depression is associated with twice the mortality after a cardiovascular event. The objectives of this study were to describe and compare depressive symptoms pre- and postcardiac rehabilitation (CR) among patients in high-income countries and middle-income countries in the Americas.

Actinomyces spp have been increasingly associated with endodontic infections. However, the antimicrobial susceptibility of this genus has not been studied extensively. The objective of this study was to determine the susceptibility of oral isolates of Actinomyces naeslundii, Actinomyces gerencseriae, Actinomyces israelii, Actinomyces viscosus, and Actinomyces odontolyticus to amoxicillin, clindamycin, doxycycline, metronidazole, and moxifloxacin using in vitro assays.

Bacteria remaining within the root canal system are a significant factor in endodontic failures. The aim of this in vitro study was to evaluate the antimicrobial efficacy of commercially available gutta-percha formulations against common endodontic pathogens. Standard, tetracycline, or iodoform (also called medicated gutta-percha; MGP) containing gutta-percha were tested against Actinomyces israelii, A.
