Abnormal aggregation and accumulation of alpha-synuclein (αSN) in existing neurons is associated with Parkinson's disease (PD) as one of the age-related neurodegenerative disorders. Inhibition of αSN fibrillogenesis could be considered as a solution for PD diseases treatment. Here, virtual screening (VS) approach was used to investigate available ligands in PubChem library with structural similarity with Dihydromyricetin (DHM) (as a recently introduced suitable candidate for designing of novel antiPD drugs) against aggregation of αSN chains. Primary screening identified 314 promising molecules for αSN monomer, which were further analyzed in details by their binding energy and binding modes through molecular docking method. Evidently, the compound with PubChem ID of 100968625 displayed the lowest free binding energy with ΔG0 = -7.1 kcal.mol-1 and was selected for further analysis using molecular dynamics (MD) simulation method. Analysis of MD trajectories showed that molecules of the selected ligand interact with αSN trimer via H-bond interaction and destabilize the compact structure of αSN trimer. Further, prompt in vivo testing to validate the antiPD inhibition efficiency by this molecule can save lives.Correct virtual reconstruction of a defective skull is a prerequisite for successful cranioplasty and its automatization has the potential for accelerating and standardizing the clinical workflow. This work provides a deep learning-based method for the reconstruction of a skull shape and cranial implant design on clinical data of patients indicated for cranioplasty. The method is based on a cascade of multi-branch volumetric CNNs that enables simultaneous training on two different types of cranioplasty ground-truth data the skull patch, which represents the exact shape of the missing part of the original skull, and which can be easily created artificially from healthy skulls, and expert-designed cranial implant shapes that are much harder to acquire. The proposed method reaches an average surface distance of the reconstructed skull patches of 0.67 mm on a clinical test set of 75 defective skulls. It also achieves a 12% reduction of a newly proposed defect border Gaussian curvature error metric, compared to a baseline model trained on synthetic data only. Additionally, it produces directly 3D printable cranial implant shapes with a Dice coefficient 0.88 and a surface error of 0.65 mm. The outputs of the proposed skull reconstruction method reach good quality and can be considered for use in semi- or fully automatic clinical cranial implant design workflows.

Granular dystrophy is the most common stromal dystrophy. To perform automated segmentation of corneal stromal deposits, we trained and tested a deep learning (DL) algorithm from patients with corneal stromal dystrophy and compared its performance with human segmentation.

In this retrospective cross-sectional study, we included slit-lamp photographs by sclerotic scatter from patients with corneal stromal dystrophy and real-world slit-lamp photographs via various techniques (diffuse illumination, tangential illumination, and sclerotic scatter). Our data set included 1007 slit-lamp photographs of semi-automatically generated handcraft masks on granular and linear lesions from corneal stromal dystrophy patients (806 for the training set and 201 for test set). For external test (140 photographs), we applied the DL algorithm and compared between automated and human segmentation. For performance, we estimated the intersection of union (IoU), global accuracy, and boundary F1 (BF) score for segmentation.

In 201 d dataset and showed reasonable performance in a real-world setting. We suggest this automatic segmentation of corneal deposits helps to monitor the disease and can evaluate possible new treatments.A novel highly selective and sensitive turn-on fluorescent chemosensor PCE to recognize Zn2+ has been developed. The sensor PCE displays a remarkable fluorescent enhancement at 456 nm (λex = 340 nm) with Zn2+ without the interference of other biologically important relevant metal ions in aqueous acetonitrile solution. Job's plot and mass spectral studies divulge such the interaction of PCE by Zn2+ was 11 binding stoichiometry. The association constant and detection limit of PCE to recognize Zn2+ was found to be 0.948 × 104 M-1 and 4.82 × 10-7 M respectively. The nature of turn-on fluorescence sensor was supported by TD-DFT calculations. And the synthesized probe PCE was able to image intracellular Zn2+ in living cells using confocal imaging techniques. PCE-Zn ensemble showed the remarkable fluorescence enhancement with ATP selectively among other biologically important phosphates. 31P NMR experiments suggesting that the triphosphates unit of ATP is intact with the PCEZn. PCE-Zn ensemble can be utilized for monitoring ATP in live cells.In this review, we highlight the interaction of SARS-CoV-2 virus and host genomes, reporting the current studies on the sequence analysis of SARS-CoV-2 isolates and host genomes from diverse world populations. The main genetic variants that are present in both the virus and host genomes were particularly focused on the ACE2 and TMPRSS2 genes, and their impact on the patients' susceptibility to the virus infection and severity of the disease. Finally, the interaction of the virus and host non-coding RNAs is described in relation to their regulatory roles in target genes and/or signaling pathways critically associated with SARS-CoV-2 infection. Altogether, these studies provide a significant contribution to the knowledge of SARS-CoV-2 mechanisms of infection and COVID-19 pathogenesis. The described genetic variants and molecular factors involved in host/virus genome interactions have significantly contributed to defining patient risk groups, beyond those based on patients' age and comorbidities, and they are promising candidates to be potentially targeted in treatment strategies for COVID-19 and other viral infectious diseases.The highly pathogenic avian influenza (HPAI) H5N8 virus of clade 2.3.4.4 was detected in 2017 in Egypt, which is one of the few countries using vaccination as a control strategy in poultry farms. This study was conducted to evaluate the efficacy of the commercial recombinant turkey herpes virus-H5 (rHVT-H5) vaccine (clade 2.2), alone or in combination with commercial inactivated reverse genetically engineered H5N1 vaccine (rgH5N1) (clade 2.2), in preventing the genetically distinct HPAI H5N8 virus of clade 2.3.4.4b in commercial broiler chickens. Four experimental groups of chickens were used as follows G1, non-vaccinated and non-challenged; G2, non-vaccinated and challenged; G3, vaccinated with rHVT-H5; and G4, prime-boost vaccinated with rHVT-H5/rgH5N1. For challenge with the Egyptian HPAI H5N8 (2.3.4.4b) virus, the groups were divided into two subgroups (A and B); chickens in subgroups A were challenged at the age of 28 days, whereas those in subgroups B were challenged at the age of 35 days. Results showend viral shedding) caused by the genetically distinct virus (clade 2.3.3.4b HPAI H5N8) in combination with strict biosecurity and sanitary measures.The use of regenerative medicine for pets has been growing in recent years, and an increasing number of studies have contributed to the widespread use of cell therapies in clinical veterinary medicine. Mesenchymal stem cells (MSCs) can be isolated from different sources such as dental pulp and umbilical cord. Aiming safety and reproducibility of cell therapy in clinical practice by using sources easily obtained that are usually discarded, this study isolated, characterized, and evaluated the proliferation and colony formation potential of canine dental pulp-derived mesenchymal stem cells (cDPSCs) and canine umbilical cord tissue (cUCSCs). Three samples from each source were collected, isolated, and cultured. find more MSCs were differentiated into three lineages and quantified by spectrophotometry. For immunophenotypic characterization, antibodies were used to analyze the expression of cell surface markers, and 7-AAD and Annexin-V were used to analyze cell viability and apoptosis, respectively. For the clonogenic assay, cells were cultured, the colonies were stained, and counted. For the proliferation assay, the cells were plated in flasks for three days and added EdU nucleoside. cDPSCs and cUCSCs showed plastic adherence and fibroblastic morphology after cultivation. Both sources showed differentiation potential and showed CD29 and CD44 positivity and CD14, CD45, CD34 and HLA-DR negativity, and low mortality and apoptosis rates. There was no difference in proliferation rates between sources. Overall, although cUCSCs had a higher number of colony-forming units than cDPSCs, both sources presented MSCs characteristics and can be used safely as alternative sources in cell therapy.

Studies from certain regions of the world indicate that consanguineous marriages are a risk factor for the development of schizophrenia in offspring. However the evidence is inconsistent partly due to methodological limitation of which hospital based recruitment contributing to significant bias. The studies from the Indian subcontinent, is scarce, where rates of consanguinity is high.

The schizophrenia patients living in a geographically defined rural south Indian community and randomly selected controls dwelling in the same community sharing sociocultural, economic and lifestyle factors were recruited. They were assessed for parental consanguinity using the clinical interviews as well as DNA-based estimates. The latter was conducted by calculating the coefficient of inbreeding 'f'. A participant was considered to have consanguineous parentage if his/her parents shared a common ancestor no more remote than a great-great-grandparent, corresponding to DNA-based estimates of 'f' ≥ 0.0156.

The rates of parental consanguinity assessed by clinical interview were comparable in both groups (Cases 10.71 %, Controls 7.25 %; χ

= 0.493, p = 0.4825). However, DNA-based rates of parental consanguinity showed that 'f' was significantly higher among cases than controls (Mann-Whitney U = 11315.5; p = 0.022). Seventy-five cases (62.5 %) and 108 control participants (48.6 %) had 'f' ≥ 0.0156 (χ

= 6.008; p = 0.014). The results were consistent across different quality control measures.

Schizophrenia is associated with higher parental consanguinity, suggesting a role for multiple recessive risk alleles in its etiology. Replication in future studies in diverse settings would add further strength to this.

The objective of this study was to determine if SPiN performance can be enhanced by intermittent theta-burst stimulation (iTBS) in young and older adults.

We developed a sub-lexical SPiN test to evaluate the contribution of age, hearing, and cognition to SPiN performance in young and older adults. iTBS was applied to the left posterior superior temporal sulcus (pSTS) and the left ventral premotor cortex (PMv) to examine its impact on SPiN performance.

Aging was associated with reduced SPiN accuracy. TMS-induced performance gain was greater after stimulation of the PMv compared to the pSTS. Participants with lower scores in the baseline condition improved the most.

SPiN difficulties can be reduced by enhancing activity within the left speech-processing network in adults. This study paves the way for the development of TMS-based interventions to reduce SPiN difficulties in adults.
