Can human maxillary premolar crown dimensions discriminate between males and females?

Studies showed that odontometry can be used to analyse the influence of sexual dimorphism on the size of the teeth in specific ancestries. The aim of this study was to explore the bucco-lingual dimensions expressed as a ratio of human maxillary premolar crowns in males and females from polled ancestries. ethnicities If this measurement could discriminate sex, it would have application in forensic cases, mass disasters and archaeology where the number of mingled human remains is high and the ancestry ethnicity is unknown or multiple; Moreover, methodologies applied on radiographs or biochemical analysis in the laboratory is not always possible. The sample studied consisted of unworn premolars from 51 skeletal remains, 19 females and 32 males of known sex from collections: the Hunterian Museum, Royal College of Surgeons, England and the Natural History Museum, London and 100 archived orthodontic plaster casts of young adult dental patients (50 females and 50 males) of Royal London Hospital. Digital photographs were taken parallel to the occlusal surface and intercuspal distance and maximum bucco-lingual distance were captured using ImageJ 1.47v (U. S. National Institutes of Health, Maryland, USA), and the ratio of both distances calculated. Results were compared using a t-test and showed that for both upper premolars, the overall ratio was greater in males than females; however this was not significantly different to zero. The overall ratio for first premolar (P1) was less than second premolar (P2) in males and females. These findings show that maxillary premolar, measured in this way, are not significantly different and cannot discriminate between the sexes in this sample of different ancestries

Significant social networks and violence against women : perspective of professionals from a shelter

This qualitative study identified the structural characteristics of the significant social networks constituted in the context of the sheltering of women in situations of violence. Ten professionals were interviewed from a shelter located in the South of Brazil. The organization and analysis of the data was based on the Grounded Theory and software Atlas.ti 7.0. During the women's stay, the professionals noted networks that: (a) wanted to offer help but were unable to ensure safety, (b) made it difficult to leave the shelter for religious or cultural reasons, (c) could help with these women's social reintegration. The professionals considered the significant social networks as key elements for the rescue of bonds broken by the situation of violenceEste estudio cualitativo identificó las características estructurales de las redes sociales significativas en torno al proceso de acogida de mujeres en situación de violencia. Se entrevistó 10 profesionales de una casa de acogida de la región Sur de Brasil. La organización y análisis de los datos tuvieran como referencia la teoría fundamentada (grounded theory) y el software Atlas ti.7.0. Las profesionales observaron que las redes: (a) querían ofrecer ayuda, pero no podían proporcionar seguridad, (b) dificultaron la salida de la casa-abrigo por cuestiones religiosas o culturales, (c) podrían ayudar en la reinserción social de las mujeres. Para estos profesionales, las redes sociales significativas son elementos claves para el rescate de los lazos rotos por la situación de violenciaEste estudo qualitativo identificou as características estruturais das redes sociais significativas, configuradas em torno do processo de abrigamento de mulheres em situação de violência. Foram entrevistadas 10 profissionais de uma casa-abrigo localizada na Região Sul do Brasil. A organização e análise dos dados baseou-se na Teoria Fundamentada (Grounded Theory) e software Atlas.ti 7.0.

As profissionais visualizaram as redes sociais significativas como elemento-chave para o resgate dos vínculos, rompidos pela situação de violênci

Importància de les cases d'acollida en l'afrontament de les repercussions de la violència envers les dones

L'objectiu de les cases d'acollida per a dones en situació de violència en la parella és assegurar l'ajuda i la protecció de la integritat física i psicològica de les dones i els seus fills i filles menors que estan en risc imminent de mort. A partir d'entrevistes a 12 dones que havien viscut situacions de violència i havien estat en cases d'acollida al Brasil, aquest estudi ha analitzat les repercussions del procés d'acollida sobre la dinàmica relacional familiar de les dones en situació de violència per tal de conèixer l'eficàcia d'aquests serveis

Resonances arising from sheltering in the family dynamics of Brazilian women in situations of violence

This study aimed to analyze the repercussions of sheltering in the family dynamics of women in situations of violence. This is a qualitative study in which 12 Brazilian women who were given shelter due to have suffered from violence were interviewed. The data organization and analysis was supported by the Grounded Theory, with the help of Atlas.ti software. Before being in the shelter, the study revealed the hardening of family relations and breaking of affectional bonds as well feelings of anxiety, depression, shame, fear and humiliation. Their permanence in the shelter helped the women to create strategies of coping with violence, which in turn, contributed to their reintegration in society as well as the recovery of their dignity and citizenshipEste estudio tuvo como objetivo analizar los efectos del proceso de acogimiento en la dinámica familiar de mujeres brasileñas en situaciones de violencia. Es un estudio cualitativo basado en entrevistas a doce mujeres que sufrieron violencia y que estuvieron en casa de acogida. La organización y el análisis de los datos tuvieron como referencia la teoría fundamentada y el auxilio del software Atlas.ti 7.0. En el período anterior al proceso de acogida, los resultados mostraron el endurecimiento de las relaciones familiares y la ruptura de lazos afectivos, así como la presencia de ansiedad, estados depresivos, vergüenza, miedo y humillación. El proceso de acogimiento hizo posible la creación de estrategias de afrontamiento al problema de la violencia, promoviendo la reinserción social de las mujeres y el rescate de su dignidad y ciudadaní

A simple RP-HPLC method for the determination of clotrimazole from acrylic nanocapsule suspensions

A simple and fast HPLC method has been validated for the determination of clotrimazole in nanocapsule suspensions prepared from an acrylic polymer, Eudragit RS100®. Chromatographic runs were performed on a RP C18 column with a mobile phase comprising methanol and water (90:10, v/v) at a flow rate of 1.0 mL/min with UV detection at 229 nm. The method was shown to be specific, linear (r = 0.9987), precise and accurate in a concentration range of 2.0-10.0 μg/mL. The proposed method can be successfully used to quantify clotrimazole content in acrylic nanocapsule formulations, as well as to estimate drug encapsulation efficiency.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Diagnostic Performance of convolutional neural networks for dental sexual dimorphism

Convolutional neural networks (CNN) led to important solutions in the field of Computer Vision. More recently, forensic sciences benefited from the resources of artificial intelligence, especially in procedures that normally require operator-dependent steps. Forensic tools for sexual dimorphism based on morphological dental traits are available but have limited performance. This study aimed to test the application of a machine learning setup to distinguish females and males using dentomaxillofacial features from a radiographic dataset. The sample consisted of panoramic radiographs (n = 4003) of individuals in the age interval of 6 and 22.9 years. Image annotation was performed with V7 software (V7labs, London, UK). From Scratch (FS) and Transfer Learning (TL) CNN architectures were compared, and diagnostic accuracy tests were used. TL (82%) performed better than FS (71%). The correct classifications of females and males aged ≥ 15 years were 87% and 84%, respectively. For females and males < 15 years, the correct classifications were 80% and 83%, respectively. The Area Under the Curve (AUC) from Receiver-operating Characteristic (ROC) curves showed high classification accuracy between 0.87 and 0.91. The radio-diagnostic use of CNN for sexual dimorphism showed positive outcomes and promising forensic applications to the field of dental human identification
