FedPD: Defending federated prototype learning against backdoor attacks.

Federated Learning (FL) is an efficient, distributed machine learning paradigm that enables multiple clients to jointly train high-performance deep learning models while maintaining training data locally. However, due to its distributed computing nature, malicious clients can manipulate the prediction of the trained model through backdoor attacks. Existing defense methods require significant computational and communication overhead during the training or testing phases, limiting their practicality in resource-constrained scenarios and being unsuitable for the Non-IID data distribution typical in general FL scenarios.

Exposure to leachates of plastic food containers disturbs glucose and lipid metabolism: Insights from models mimicking real-exposure scenarios.

The increasing use of plastic food containers, particularly for pre-cooked meals and takeout services, has raised concerns regarding the potential health risks associated with plastic leachates. This study investigated the impact of leachates from heat-treated polypropylene (PP) plastic food containers on glucose and lipid metabolism using both in vitro and in vivo models. AML12 hepatocytes exposed to leachates from three different PP plastic containers exhibited significant disruptions in the homeostasis of lipid and glucose metabolism, evidenced by increased intracellular lipid content and altered gene expression related to lipogenesis, lipid uptake, lipolysis, and fatty acid β-oxidation.

Elaborate Structural Modifications Yielding Novel Boron-Containing N-Substituted Oseltamivir Derivatives as Potent Neuraminidase Inhibitors with Significantly Improved Broad-Spectrum Antiresistance Profiles.

Inspired by our previous finding that targeting the 150-cavity with a multisite-binding strategy emerged as an effective approach to obtain more potent and selective neuraminidase (NA) inhibitors against influenza virus, we present here the design, synthesis, and optimization of novel boron-containing N-substituted oseltamivir (OSC) derivatives. Exploratory structure-activity relationship (SAR) studies led to the identification of compounds and as the most potent NA inhibitors, surpassing OSC in potency against both wild-type group-1 NAs and oseltamivir-resistant NAs. These compounds demonstrated significant antiviral activity against several wild-type strains and H1N1pdm09 strains (EC = 0.

Quantitative Proteomic Analysis of APP/PS1 Transgenic Mice.

Background: Alzheimer's disease (AD) is a prevalent neurodegenerative disorder affecting the central nervous system (CNS), with its etiology still shrouded in uncertainty. The interplay of extracellular amyloid-β (Aβ) deposition, intracellular neurofibrillary tangles (NFTs) composed of tau protein, cholinergic neuronal impairment, and other pathogenic factors is implicated in the progression of AD.

Objective: The current study endeavors to delineate the proteomic landscape alterations in the hippocampus of an AD murine model, utilizing proteomic analysis to identify key physiological and pathological shifts induced by the disease.

We conducted a series of experiments to investigate the engineering characteristics and microscopic mechanism of the backfill.

Study of the Macro and Micro Characteristics of and Their Relationships in Cemented Backfill Based on SEM.

Nuclear magnetic resonance can only quantitatively obtain porosity and pore size distribution, but as a conventional microstructure observation technology, scanning electron microscope (SEM) can select different magnifications to observe the microstructure of backfill materials. However, the processing of SEM images is not deep enough. In this paper, Image-Pro Plus 6.

Role of Gltp in Maturation of Oligodendrocytes Under the Regulation of Nkx2.2.

Myelin, a lipid-enriched multi-layer membrane structure, allows for rapid long-distance saltatory conduction of neuronal impulses. Although glycolipids are the predominant types of lipids in the myelin bilayer, the role of glycolipid transfer protein (GLTP), which selectively mediates the transfer of various glycolipids between phospholipid bilayer, in myelin development and maintenance remains unknown at present. In this study, we identified Gltp as the key lipid metabolism gene in myelin-forming oligodendrocytes (OLs) through integrated omics analysis across independent transcriptomic and single-cell sequencing studies.

CircXPO1 Promotes Glioblastoma Malignancy by Sponging miR-7-5p.

Mounting evidence suggests that circular RNAs play important roles in the development and progression of cancers. However, their function in glioblastomas (GBM) is still unclear. By circRNA array analysis, we found that circXPO1 (hsa_circ_102737) was significantly upregulated in GBM, and qPCR analysis verified that the circXPO1 expression level was increased in both GBM tissues and cell lines.

Urinary Sodium Excretion and Salt Intake Are Not Associated With Blood Pressure Variability in a White General Population.

Background Salt restriction may lower blood pressure variability (BPV), but previous studies have shown inconsistent results. Therefore, we investigated in an observational study and intervention trial whether urinary sodium excretion and salt intake are associated with 24-hour BPV. Methods and Results We used data from the cross-sectional population-based Maastricht Study (n=2652; 60±8 years; 52% men) and from a randomized crossover trial (n=40; 49±11 years; 33% men).

Cardiovagal baroreflex sensitivity, blood pressure and blood pressure variability - the Maastricht study.

Objective: Low baroreflex sensitivity (BRS) has been hypothesized to underlie high blood pressure (BP) and greater BP variability on the longer term, but evidence is scarce. In addition, these associations may differ by sex and (pre)diabetes. Therefore, we investigated whether cardiovagal BRS is associated with short- to mid-term mean BP and BP variability, and differs according to sex and (pre)diabetes.

Cross-Project Defect Prediction Based on Two-Phase Feature Importance Amplification.

As the typical application of computational intelligence in software engineering, cross-project defect prediction (CPDP) uses labeled data from other projects (source projects) for building models to predict the defects in the current projects (target projects), helping testers quickly locate the defective modules. But class imbalance and different data distribution among projects make CPDP a challenging topic. To address the above two problems, we propose a two-phase feature importance amplification (TFIA) CPDP model in this paper which can solve these two problems from domain adaptation phase and classification phase.

Aberrant nuclear lamina contributes to the malignancy of human gliomas.

Glioma is the most common type of tumor in the central nervous system, accounting for around 80% of all malignant brain tumors. Previous studies showed a significant association between nuclear morphology and the malignant progress of gliomas. By virtue of integrated proteomics and genomics analyses as well as experimental validations, we identify three nuclear lamin genes (LMNA, LMNB1, and LMNB2) that are significantly upregulated in glioma tissues compared with normal brain tissues.

Carotid stiffness is associated with retinal microvascular dysfunction-The Maastricht study.

Objective: This study investigated whether arterial stiffening is a determinant of subtle retinal microvascular changes that precede diabetic retinopathy.

Research Design And Methods: This study used cross-sectional data from the Maastricht Study, a type 2 diabetes-enriched population-based cohort study. We used multivariable linear regression analysis to investigate, in individuals without and with type 2 diabetes, the associations of carotid distensibility coefficient and carotid-femoral pulse wave velocity with retinal microvascular diameters and flicker light-induced dilation and adjusted for cardiovascular and lifestyle risk factors.

Exercise SBP response and incident depressive symptoms: The Maastricht Study.

Objective: : An exaggerated exercise SBP, which is potentially modifiable, may be associated with incident depressive symptoms via an increased pulsatile pressure load on the brain. However, the association between exaggerated exercise SBP and incident depressive symptoms is unknown. Therefore, we examined whether exaggerated exercise SBP is associated with a higher risk of depressive symptoms over time.

Blood pressure variability and microvascular dysfunction: the Maastricht Study.

Background: Microvascular dysfunction (MVD) contributes to stroke, dementia, depression, retinopathy and chronic kidney disease. However, the determinants of MVD are incompletely understood. Greater blood pressure variability (BPV) may be one such determinant.

Both Prediabetes and Type 2 Diabetes Are Associated With Lower Heart Rate Variability: The Maastricht Study.

Objective: Low heart rate variability (HRV), a marker for cardiac autonomic dysfunction, is a known feature of type 2 diabetes, but it remains incompletely understood whether this also applies to prediabetes or across the whole glycemic spectrum. Therefore, we investigated the association among prediabetes, type 2 diabetes, and measures of glycemia and HRV.

Research Design And Methods: In the population-based Maastricht Study ( = 2,107; mean ± SD age 59 ± 8 years; 52% men; normal glucose metabolism [ = 1,226], prediabetes [ = 331], and type 2 diabetes [ = 550, oversampled]), we determined 24-h electrocardiogram-derived HRV in time and frequency domains (individual -scores, based upon seven and six variables, respectively).

TPGS-1000 exhibits potent anticancer activity for hepatocellular carcinoma and .

D-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS1000) is the most active water-soluble derivative of vitamin E and has been widely used as a carrier of solvents, plasticizers, emulsifiers, absorbent agents and refractory drug delivery systems. However, its anti-hepatocellular carcinoma (HCC) properties have not been explored. HCC cells were treated with different concentrations of TPGS1000.

Microscopic characterization and strength characteristics of cemented backfill under different humidity curing conditions.

Under different exploitive conditions, the humidity levels of the backfill stopes are not the same. Humidity greatly affects the strength and microscopic characterization of the backfill. Cemented paste backfill (CPB) specimens were cured using 0, 30, 70% and standard curing (20°C, 99%) under four different humidity conditions.

Greater Blood Pressure Variability Is Associated With Lower Cognitive Performance.

An increasing number of individuals will face age-related cognitive difficulties because life expectancy has increased. It is, therefore, important to identify modifiable risk factors for cognitive impairment. Very short-term to mid-term blood pressure variability (BPV) may be such a factor because it may cause cerebral ischemia.

Blood Pressure Variability, Arterial Stiffness, and Arterial Remodeling.

Greater very short- to midterm blood pressure variability (BPV) has been associated with an increased cardiovascular disease risk, especially stroke. However, this link remains incompletely understood. We hypothesized that increased arterial stiffness and maladaptive carotid arterial remodeling may underlie this association.
