bimaculata, but the impact of the parasitism did not differ between the parasite species. The size of the abdominal flap of male hosts was reduced by the bopyrid infestation; however, rhizocephalan infestation caused enlargement of the abdominal flap, which is an indication of feminization. The present study provides information on how the effect of these two parasitic castrators on the same host crab varies. A moderate decrease in crab condition and cheliped development was common among the parasites, suggesting that the degree of impact might be favorable for the survival of the two parasites species.
Anxiety disorder is a common non-motor symptom in patient with Parkinson's disease (PD). We aimed to explore its pathogenesis and identify plasma biomarkers using untargeted metabolomics analysis.
Consecutive PD patients and healthy controls were recruited. Clinical data were assessed and patients with Parkinson's disease related anxiety disorder (PDA) were recognized. Fast plasma samples were obtained and untargeted liquid chromatography-mass spectrometry-based metabolomics analysis was performed. Based on the differentially expressed metabolites from the above metabolomics analysis, correlation analyses and receiver operating characteristic curves (ROC) were further employed.
According to the clinical data, PDA patients had lower plasma levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol, and apolipoprotein B. There were thirty-nine differentially expressed metabolites in PDA patients when compared with the other two groups from the metabolomics analysis, respectively. Fourteen lipid metabolites were simultaneously altered between these two groups, and all of them were significantly decreased. They can be further subcategorized into fatty acyls, glycerolipids, sterol lipids, sphingolipids, and prenol lipids. The plasma levels of thirteen metabolites were negatively correlated with HAMA scores except 10-oxo-nonadecanoic acid. Based on the ROC curves, the fourteen lipid metabolites can be diagnostic biomarkers for PDA patients separately and the areas under the curve of the fourteen lipid metabolites ranged from 0.681 to 0.798.
Significantly lower plasma lipoproteins can be found in PDA patients. A panel of fourteen lipid metabolites were also significantly decreased and can be clinical biomarkers for the diagnosis of PDA patients.

Iron dyshomeostasis (especially cellular iron overload) is considered to be a critical condition of neurodegeneration. The etiopathogenesis of many neurodegenerative diseases including Alzheimer's and Parkinson's diseases, Multiple sclerosis, and others, is different. However, there are several identical cellular processes, such as iron dyshomeostasis (an excessive iron deposition), iron-induced oxidative stress, the accumulation of lipid-generated reactive oxygen species, and ferroptosis that accompany these diseases. Based on the existing theoretical and experimental evidence, the article provides current insight into iron dyshomeostasis and ferroptosis as a contributing factor to the pathogenesis of neurodegeneration. In addition, special attention is addressed to the possible relationship between cellular iron overload and key pathological features of selected neurodegenerative diseases, such as β-amyloid and tau proteins, α-synuclein, and demyelination. The mechanism by which ferroptosis may be involved in the pathogenesis of various neurodegenerative diseases is not fully elucidated. Further experimental and clinical studies are needed to clarify the hypothesis on the potential role of ferroptosis in the pathogenesis of neurodegenerative diseases.There is converging evidence of dendritic spine dysfunction in schizophrenia. In the present study we hypothesized that the expression of key proteins involved in dendritic spine development and stability may be affected in schizophrenia. Postmortem frontal cortex (BA6) from patients with schizophrenia, major depressive disorder, bipolar disorder and healthy controls was processed for glutamate post-synaptic fraction extraction and post-synaptic density purification. Protein expression of the post-synaptic fraction and the post-synaptic density was assessed using immunoprecipitation and Western blotting respectively. The expression of the N-methyl-d-aspartate glutamate receptor (NMDAR) subunit NR2A, post-synaptic density 95 (PSD-95), Ca2+/calmodulin-dependent protein kinase II subunits α and β (CaMKIIα and β) were significantly reduced in schizophrenia. A significant decrease in the expression of NR2A was also observed in patients with major depressive disorder relative to controls, but not in patients with bipolar disorder. These results add to existing evidence for disturbed post-synaptic glutamate function and synaptic plasticity in schizophrenia. buy Nec-1s There may also be subtle disturbances in the post-synaptic glutamatergic function in major depressive disorder.SH-SY5Y human neuroblastoma cells are commonly used as neuronal models. Here, we examined different aspects of SH-SY5Y cell differentiation. Various differentiation protocols have been proposed previously, including treatments with retinoic acid, brain-derived neurotrophic factor (BDNF), cholesterol and oestradiol. We examined undifferentiated SH-SY5Y cells (UNDIFF); cells differentiated by the treatment with retinoic acid (RA); retinoic acid + BDNF (RB); and retinoic acid + BDNF + cholesterol + oestradiol (RBCE). We performed whole-cell patch-clamp recordings from these cells and nanomechanically characterised them by using atomic force microscopy (AFM). Our results indicated that Na+ currents become most pronounced in the differentiated RB cells, whereas UNDIFF SH-SY5Y cells had significantly larger K+ currents, which is a characteristic feature of cancer cells. AFM observations of these two groups showed that Young's moduli of SH-SY5Y cells increased threefold with differentiation. Furthermore, we showed a direct relationship between Na+ channel activity and elasticity in these cells.
