The second key was not able to discriminate some couples of species unambiguously, but could identify the bark fragments of the homicide as Robinia pseudoacacia, as confirmed from direct comparison with a reference sample. Bark fragments deserve to be included into the macroremains to be analyzed during an investigation, but small samples could easily lack diagnostic traits, and the building of a reference collection should be encouraged.

The teeth have been used as a supplementary tool for sex differentiation as they are resistant to post-mortem degradation. The present study aimed to develop a new novel informatics framework for predicting sex from linear tooth dimension measurements achieved from cone beam computed tomography (CBCT) images.

A clinical workflow using different machine learning methods was employed to predict the sex in the present study. The CBCT images of 485 subjects (245 men and 240 women) were evaluated for sex differentiation. Nine parameters were measured in both buccolingual and mesiodistal aspects of the teeth. We applied our dataset to Naïve Bayesian (NB), Random Forest (RF), and Support Vector Machine (SVM) as classifiers for prediction. Genetic feature selection was used to discover real features associated with sex classification.

The 10-fold cross-validation results indicated that NB had higher accuracy than SVM and RF for sex classification. The genetic algorithm (GA) indicated that the model could fit the data without using the enamel thickness and pulp height. The average classification accuracy of our clinical workflow was 92.31 %.

The results showed that NB was the best method for sex classification. The application of the first molar teeth in sex prediction indicated an acceptable level of sexual classification. Therefore, these odontometric parameters can be applied as an additional tool for sex determination in forensic anthropology.

The decomposition process of human bodies in marine environment is not well understood, and it is influenced by external variables related to the geographical area where the body is submerged. We report the application of two decomposition scores, the Heaton's score and the van Daalen's score, on a casuistry of human bodies recovered from the Northern Adriatic Sea. The aims of this study are to verify whether the marine environment of a Mediterranean climate area may affect the applicability of both scores and to develop a prediction model that can be applied on bodies recovered in salt water.

A retrospective study was performed on 61 human bodies recovered between 2005 and 2019 from coastal water of the Northern Adriatic Sea nearby the Italian regions Emilia-Romagna and Marche. For each of the 61 cases included, the Total Aquatic Decomposition Score (TADS) was calculated with the Heaton's score and the Van Daalen's score. The prediction model was assessed through multiple regression analyses, and the detnment of the Northern Adriatic Sea.

The proposed prediction models are not significantly influenced by seasonality, contrarily to what observed on bodies recovered in fresh water in the same climate area. However, the ADD model, which also consider the water temperature, should be preferred for higher decomposition stages. This study helps increase the accuracy of PMSI estimation in bodies recovered from a marine environment of the Northern Adriatic Sea.Deep learning, for image data processing, has been widely used to solve a variety of problems related to medical practices. However, researchers are constantly struggling to introduce ever efficient classification models. Recent studies show that deep learning can perform better and generalize well when trained using a large amount of data. Organizations such as hospitals, testing labs, research centers, etc. can share their data and collaboratively build a better learning model. Every organization wants to retain the privacy of their data, while on the other hand, these organizations want accurate and efficient learning models for various applications. The concern for privacy in medical data limits the sharing of data among multiple organizations due to some ethical and legal issues. To retain privacy and enable data sharing, we present a unique method that combines locally learned deep learning models over the blockchain to improve the prediction of lung cancer in health-care systems by filling the defined nodules and also achieve better performance.Accurate diagnosis of Parkinson's Disease (PD) at its early stages remains a challenge for modern clinicians. In this study, we utilize a convolutional neural network (CNN) approach to address this problem. In particular, we develop a CNN-based network model highly capable of discriminating PD patients based on Single Photon Emission Computed Tomography (SPECT) images from healthy controls. A total of 2723 SPECT images are analyzed in this study, of which 1364 images from the healthy control group, and the other 1359 images are in the PD group. Image normalization process is carried out to enhance the regions of interests (ROIs) necessary for our network to learn distinguishing features from them. A 10-fold cross-validation is implemented to evaluate the performance of the network model. Our approach demonstrates outstanding performance with an accuracy of 99.34 %, sensitivity of 99.04 % and specificity of 99.63 %, outperforming all previously published results. Given the high performance and easy-to-use features of our network, it can be deduced that our approach has the potential to revolutionize the diagnosis of PD and its management.The anatomy of red blood cells (RBCs) in blood smear images plays an important role in the detection of several diseases. The automated image-based technique is fast and accurate for the analysis of blood cells morphology that can save time of both pathologists as well as that of patients. In this paper, we propose a novel method which segment and identify varied RBCs in a given blood smear images. In the proposed method, the central pallor and whole cell information are used, after using color processing followed by double thresholding of blood smear images. The shape and size variances of cells are calculated for the identification of abnormalities in peripheral blood smear images. We used cross-validation accuracy weighted probabilistic ensemble (CAWPE). It is a heterogeneous ensembling technique of nearly equivalent classifiers produced on averagely significant better classifiers (regarding errors and probability estimates) as compared to a wide range of potential parent classifiers. The proposed method is tested on 3 sets of images. The sets of images were prepared in a local government hospital by expert pathologists. Each image set has varied photographic conditions. The method was found accurate in term of results, closer to the ground truth. The average accuracy of the proposed method is 97% for the segmentation of single cells and 96% for overlapped cells. The variance (σ2) of accuracy is 3.5 and the deviation (σ) is 1.87.Cilia are highly conserved in most eukaryotes and are regarded as an important organelle for motility and sensation in various species. Cilia are microscopic, hair-like cytoskeletal structures that protrude from the cell surface. The major focus in studies of cilia has been concentrated on the ciliary dysfunction in vertebrates that causes multisymptomatic diseases, which together are referred to as ciliopathies. To date, the understanding of ciliopathies has largely depended on the study of ciliary structure and function in different animal models. Zinc finger MYND-type containing 10 (ZMYND10) is a ciliary protein that was recently found to be mutated in patients with primary ciliary dyskinesia (PCD). In Paramecium tetraurelia, we identified two ZMYND10 genes, arising from a whole-genome duplication. Using RNAi, we found that the depletion of ZMYND10 in P. tetraurelia causes severe ciliary defects, thus provoking swimming dysfunction and lethality. Moreover, we found that the absence of ZMYND10 caused the abnormal localization of the intraflagellar transport (IFT) protein IFT43 along cilia. These results suggest that ZMYND10 is involved in the regulation of ciliary function and IFT, which may contribute to the study of PCD pathogenesis.A soil hypotrich ciliate, Afrokahliella paramacrostoma n. sp., was discovered in China. Its morphology, morphogenesis and molecular phylogeny were investigated using standard methods. The new species is characterized as follows body about 140-180 × 60-70 μm in vivo, cortical granules absent, contractile vacuole positioned about 40% down length of body, 5-9 macronuclear nodules, 34-49 adoral membranelles, 3-5 buccal and 3-6 parabuccal cirri, usually two frontoventral rows, three or four left and two or three right marginal rows, three dorsal kineties and one dorsomarginal kinety; 1-3 and one or two caudal cirri located at the ends of dorsal kineties 1 and 2, respectively. The ontogenetic process is characterized by (1) the marginal anlagen on each side develop in the outer right and the inner left marginal rows, respectively; (2) five frontoventral-transverse cirral anlagen, anlagen II-IV develop in secondary mode; (3) dorsal morphogenesis follows a typical Urosomoida-pattern, no parental dorsal kineties are retained; (4) caudal cirri are generated at the ends of dorsal kineties 1 and 2. Phylogenetic analyses based on SSU rDNA sequence data reveals that Afrokahliella paramacrostoma n. read more sp. is closely related to Parakahliella macrostoma and Hemiurosomoida longa.The Colpodea form a major clade of ciliates that are often found in environmental DNA sequencing studies. They are united by similar somatic ciliature, but differentiated by complex oral structures. Although there are four well supported colpodean subclades, there is disagreement in molecular phylogenetic inferences about their branching order. Using available nuclear SSU-rRNA sequences, we evaluated if the bursariomorphids or the platyophryids are sister to the remaining colpodeans. We inferred the "platyophryids-early" topologies using different alignment and masking methods, but constrained analyses could not reject the "bursariomorphids-early" topology. Both bursariomorphids and platyophryids clades have a similar number of nucleotide positions shared with the outgroup, and both are interconnected with the outgroup in phylogenetic networks. Based on these discordant results, it is hard to determine which clade branched off first, although the "platyophryids-early topology" is also supported by mitochondrial SSU-rRNA data. We also offer different reference alignments that can be used to phylogenetically place short- and long-read data from environmental DNA sequencing studies, and we propose some tentative evolutionary and ecological interpretations of those placements.Public awareness of language impairment in childhood (Developmental Language Disorder (DLD)) has been identified as an important determiner of research and clinical service delivery, yet studies directly assessing public awareness are lacking. This study surveyed awareness across 18 countries of Europe.

A questionnaire developed by an international team asked whether respondents had heard of language impairment affecting children, what they thought its manifestations and causes were and where they had heard of it. Respondents were also asked whether they had heard of autism, dyslexia, ADD/ADHD and speech disorder. The questionnaire was administered to members of the public in 18 European countries. A total of 1519 responses were obtained, spanning 6 age groups, 4 educational level groups and 3 income level groups.

Across all but one country, significantly fewer people had heard of language impairment than any of the other disorders (or 60 % compared to over 90 % for autism). Awareness tended to be lowest in Eastern Europe and greatest in North-Western Europe, and was influenced by education level, age and income level.
