The statistical results demonstrate that the proposed JASMA-SVM can be treated as a potential tool for RSA with accuracy of 92.998%, MCC of 0.92425, sensitivity of 93.286%, specificity of 93.064%.Parkinson's disease (PD) is a common neurodegenerative disease in the elderly population. PD is irreversible and its diagnosis mainly relies on clinical symptoms. Hence, its effective diagnosis is vital. PD has the related gene mutation called gene-related PD, which can be diagnosed not only in the specific PD patients, but also in the healthiest people without clinical symptoms of PD. Since mutations in PD-related genes can affect healthy people, and unaffected PD-related gene carriers can develop into PD patients, it is very necessary to distinguish gene-related PD diseases. The magnetic resonance imaging (MRI) has a lot of information about brain tissue, which can distinguish gene-related PD diseases. However, the limited amount of the gene-related cohort in PD is a challenge for further diagnosis. Therefore, we develop a joint learning framework called feature-based multi-branch octave convolution network (FMOCNN), which uses MRI data for gene-related cohort PD diagnosis. FMOCNN performs sample-feature selection to learn discriminative samples and features and contains a deep neural network to obtain high-level feature representation from various feature types. Specifically, we first train a cardinality constrained sample-feature selection (CCSFS) model to select informative samples and features. We then establish a multi-branch octave convolution neural network (MBOCNN) to jointly train multiple feature inputs. High/low-frequency learning in MBOCNN is exploited to reduce redundant feature information and enhance the feature expression ability. Our method is validated on the publicly available Parkinson's Progression Markers Initiative (PPMI) dataset. Experiments demonstrate that our method achieves promising classification performance and outperforms similar algorithms.

To determine the refined estimates of the surgical effects on the short- and long-term prognoses of oldest-old patients (aged ≥80 years) with glioblastomas.

Using the Surveillance, Epidemiology, and End Results registry, we identified the oldest-old patients with glioblastomas between 2005 and 2016. Propensity score matching, Kaplan-Meier analysis, Cox regression analysis, and competing risk model were used to assess the curative efficacy of the surgical treatments. Stratification and interaction analysis were performed to explore the potential interaction effects. The conditional survival rates were calculated to explore the longitudinal change in the survival probability over time.

This study enrolled 3309 patients with a median overall survival of 3 months. The overall survival differed significantly among the different surgical groups. Considering the gross total resection as reference, subtotal resection presented adjusted subdistribution hazard ratio (95% confidence interval) of 1.197 (1.052-1.362be needed to promote the therapeutic efficacy of tumor resection synergistically.

Radical surgery may have short-term benefits in the oldest-old patients with glioblastoma, with a significant increase in the 1-year survival rate. However, its contribution in the long-term outcome is limited due to decreased conditional survival rates from the second year after surgery. Prudent patient selection and improved postoperative management may be needed to promote the therapeutic efficacy of tumor resection synergistically.Insulin is a critical predictor for the function of pancreatic islet beta cells, which plays a crucial role in diagnosing diabetes and diabetes-related disorders. Herein, we propose and validate a label-free and cost-effective aptamer-based optical LC biosensor for detection of insulin based on the directional recognition of biomolecular binding events at a responsive aqueous-liquid crystal (LC) interface. The binding of insulin and aptamer adsorbed on CTAB triggers a conformational change of the aptamer from G-quadruplex to stretched structure, inducing homeotropic to planar alignment and correspondingly dark to bright optical image change of the LC films. The molecular dynamic (MD) simulation validates that the orientational transition is associated with the interaction energy changes at the interface, which is in coordination with the optical observation. This LC biosensor takes advantages of simple preparation, easy operation, rapid sensing, high specificity for insulin determination in the range of 0.1-1.0 nM within 5 min. This sensor is also applicable for insulin detection in diluted human urine and serum. Additionally, the optical cell arrays allow to detection multiple samples of the same/different biomarkers at the same time. Such a strategy offers a potential basis for monitoring other clinical biomarkers, and for point-of-care testing (POCT) as well.Although earlier research had demonstrated significant links between attachment and self-concept clarity; attachment and empathy; and self-concept clarity and empathy respectively, there had been no studies examining these associations in conjunction with one another. Therefore, the present studies explored whether individual differences in self-concept clarity would mediate the relationship between attachment orientation (i.e., attachment anxiety and attachment avoidance) and empathy (i.e., empathic concern and personal distress). In Study 1, the association between attachment orientation and self-concept clarity was examined among 602 Hungarian university students. In Study 2, the relationship between attachment and empathy was investigated through self-concept clarity among 1000 Hungarian adults. The findings from both samples revealed that attachment avoidance and anxiety were negatively related to self-concept clarity. Q-VD-Oph In Study 2, individuals with greater self-concept clarity showed greater empathic concern and lower personal distress. Attachment avoidance was associated with lower empathic concern, whereas there was no significant association with personal distress. Attachment anxiety was positively related to empathic concern and personal distress. Self-concept clarity partially mediated associations with attachment anxiety and aspects of empathy. These findings suggest the importance of attachment orientations in terms of their influence on the self with regard to interpersonal relations.Evaluation of the 63Cu(α,n)66Ga, 65Cu(α,2n) 67Ga and 65Cu(α,n)68Ga reactions was done to study the production of medical radionuclides 66Ga, 67Ga and 68Ga respectively. 63Cu(α,2n)65Ga and 65Cu(α,3n)66Ga reactions were also evaluated for the estimation of radioisotopic impurities. Cross section data of each reaction were compiled and normalized to the standard values of decay data and monitor reaction. To check the consistency of the literature data, three nuclear model calculations were performed, using nuclear model codes; TAYLS 1.9, ALICE-IPPE, and EMPIRE 3.2. A well-developed evaluation methodology based on the normalized experimental data and nuclear model calculations was used to generate the statistically fitted cross sections. From the fitted cross sections, thick target yields for each reaction were calculated for the estimation of radioisotopic impurities. Finally, a suitable energy region for the production of 66Ga, 67Ga and 68Ga was suggested with a minimum level of radioisotopic impurities.

Iron deficiency may be a risk factor for thyroid disorder; however, the relationship between iron deficiency and thyroid disorder as well as mechanism involved remain unclear.

A hospital-based cross-sectional study was conducted to analyze the correlation between iron status and thyroid hormone levels in pregnant women. A total of 2218 pregnant women were recruited, and iron status and thyroid hormones were measured. Canonical correlation, Lasso regression, and Receiver operator characteristic (ROC) curve analysis were used to determine the association and related factors.

There were 219 cases with iron deficiency anemia (IDA), 168 cases with iron deficiency (ID), and 1831 subjects with normal iron status. Compared with normal group, free triiodothyronine (FT3) and free thyroxine (FT4) in ID group and IDA group had a significant decreasing trend (P<0.05), with the lowest levels in IDA group. Thyroid stimulating hormone (TSH) was significantly increased in ID group and IDA group (P<0.05). Moreover,roid hormone levels in pregnant women, and the level of FT4 may change with iron status. Our findings provide new ideas for regulating the thyroid hormone levels to prevent thyroid dysfunction during pregnancy.Nanomaterials play an important role in the fields of electrocatalysis and electrochemical immunosensor. As we all know, electrocatalytic oxygen evolution reaction (OER) can generate intensive current response under alkaline and even neutral conditions, and no by-products are produced. In recent years, OER based on non-noble metal nanocatalysts has become a research focus in the field of new energy, but there are few reports on using it as an electrocatalytic immunosensor label for biomolecule detection. In this study, we successfully synthesized CoFe-(oxy)hydroxide nanosheets through transforming CoFe prussian blue analogue (CoFe PBA). Based on the excellent OER activity of CoFe-(oxy)hydroxide in neutral solution, it was used as a new electrocatalytic marker for capturing procalcitonin (PCT) secondary antibody (Ab2). Meanwhile, gold nanoparticles (Au NPs) modified glassy carbon electrode (GCE) was utilized as immunosensor platform to immobilize PCT primary antibodies (Ab1). The linear range of the immunosensor for PCT detection is 0.0005 ∼ 100 ng mL-1, and the detection limit is 0.33 pg mL-1. Furthermore, a high recovery was obtained when this proposed method was applied to analysis human serum samples. This work not only provides a new method for clinical analysis of PCT, but also extends the application of electrocatalytic OER.In this study, we develop a characterization of bacterial spore resistance to NIR pulsed light under modalities traditionally used in multiphoton microscopy. Energy dose and laser power are both key parameters in spore and bacterial cell inactivation. Surprisingly, spores and vegetative cells seem to show a similar sensitivity to pulsed NIR, spores being only 2-fold more resistant than their vegetative counterparts. This work enables us to eliminate certain hypotheses concerning the main driver of spore inactivation processes. Our findings suggest that damage leading to inactivation is mainly caused by photochemical reactions characterized by multiple possible pathways, including DNA damage or oxidation processes.The treatment efficacy of anticancer drugs in complex physiological environments is still restricted by multi-drug resistance. To overcome this issue, a nanodrug system of HA-SS@CuS@ZIF-8@TPZ&TBMACN (HSCZTT) that breaks through the detoxification barrier for tirapazamine (TPZ) delivery was developed in this manuscript. In addition to the photothermal effect aroused by CuS in HSCZTT, which can damage tumour cells, TBMACN with photostable fluorescence in the aggregate state can also generate sufficient reactive oxygen species (ROS) to destroy tumour cells. The continuous consumption of oxygen in PDT aggravates the hypoxic environment of tumours, which further activates the TPZ released in the acidic microenvironment of the tumour to achieve apoptosis of the tumour cells. The HSCZTT can not only target the CD44 receptor overexpressed on the surface of the cancer cell, but can also effectively consume a large amount of glutathione (GSH) through the disulphide bond-modified hyaluronic acid, which serves as a targeted disulphide bond, interfering with the detoxification barrier.
