Machine learning analysis of population-wide plasma proteins identifies hormonal biomarkers of Parkinson's Disease.

As the number of Parkinson's patients is expected to increase with the growth of the aging population there is a growing need to identify new diagnostic markers that can be used cheaply and routinely to monitor the population, stratify patients towards treatment paths and provide new therapeutic leads. Genetic predisposition and familial forms account for only around 10% of PD cases [1] leaving a large fraction of the population with minimal effective markers for identifying high risk individuals. The establishment of population-wide omics and longitudinal health monitoring studies provides an opportunity to apply machine learning approaches on these unbiased cohorts to identify novel PD markers.

Mitochondrial DNA Copy Number as a Potential Biomarker for the Severity of Motor Symptoms and Prognosis in Parkinson's Disease.

Background: Mitochondrial function influences Parkinson's disease (PD) through the accumulation of pathogenic alpha-synuclein, oxidative stress, impaired autophagy, and neuroinflammation. The mitochondrial DNA copy number (mtDNA-CN), representing the number of mitochondrial DNA copies within a cell, serves as an easily assessable proxy for mitochondrial function.

Objective: This study aimed to assess the diagnostic and prognostic capabilities of mtDNA-CN in PD.

Additional Dose of Intravenous Dexamethasone Can Replace Patient-Controlled Analgesia in Pain Control after Total Knee Arthroplasty while Reducing Opioid Complications.

Purpose The purpose of this study was to evaluate whether IV dexamethasone, within the current multimodal pain management protocol, (1) could maintain postoperative pain at a comparable level without IV PCA, (2) could reduce opioids-related side effects, and (3) whether an additional dose of dexamethasone on POD 2 would offer further pain-relieving effect without increasing the risk of complications. Methods A total of 178 patients (182 knees) who underwent total knee arthroplasty (TKA) for osteoarthritis were included in the study. The patients were divided into Dexa 2 & PCA and Dexa 3 & NoPCA group.

Robust and inducible genome editing via an all-in-one prime editor in human pluripotent stem cells.

Prime editing (PE) allows for precise genome editing in human pluripotent stem cells (hPSCs), such as introducing single nucleotide modifications, small insertions or deletions at a specific genomic locus. Here, we systematically compare a panel of prime editing conditions in hPSCs and generate a potent prime editor, "PE-Plus", through co-inhibition of mismatch repair and p53-mediated cellular stress responses. We further establish an inducible prime editing platform in hPSCs by incorporating the PE-Plus into a safe-harbor locus and demonstrated temporal control of precise editing in both hPSCs and differentiated cells.

Enrichment and MALDI-TOF-MS/MS analysis of phosphatidylinositol bisphosphates in brain tissue.

A 6-9 GHz 1.28 Gbps 76 mW Amplitude and Synchronized Time Shift Keying IR-UWB CMOS Transceiver for Brain Computer Interfaces.

This paper proposes a low-power, high-speed impulse radio-ultra-wideband (IR-UWB) transceiver for brain computer interfaces (BCIs) using amplitude and synchronized time shift keying technique (ASTSK). The proposed IR-UWB transmitter (Tx) generates two pulses (sync pulse and data pulse) per symbol rate. The time difference between two pulses is used for synchronized time shift keying and the amplitude of the two pulses is used for amplitude shift keying.

Real-time capture of nuclear motions influencing photoinduced electron transfer.

Although vibronic coupling phenomena have been recognized in the excite state dynamics of transition metal complexes, its impact on photoinduced electron transfer (PET) remains largely unexplored. This study investigates coherent wavepacket (CWP) dynamics during PET processes in a covalently linked electron donor-acceptor complex featuring a cyclometalated Pt(ii) dimer as the donor and naphthalene diimide (NDI) as the acceptors. Upon photoexciting the Pt(ii) dimer electron donor, ultrafast broadband transient absorption spectroscopy revealed direct modulation of NDI radical anion formation through certain CWP motions and correlated temporal evolutions of the amplitudes for these CWPs with the NDI radical anion formation.

Placental growth factor deficiency initiates obesity- and aging-associated metabolic syndrome.

Obesity often leads to inadequate angiogenesis in expanding adipose tissue, resulting in inflammation and insulin resistance. We explored the role of placental growth factor (PlGF) in metabolic syndrome (MS) using mice models of type 2 diabetes, high-fat diet, or aging. Reduced serum PlGF levels were associated with decreased insulin sensitivity and development of MS features.

Structural dynamics of protein-protein association involved in the light-induced transition of Avena sativa LOV2 protein.

The Light-oxygen-voltage-sensing domain (LOV) superfamily, found in enzymes and signal transduction proteins, plays a crucial role in converting light signals into structural signals, mediating various biological mechanisms. While time-resolved spectroscopic studies have revealed the dynamics of the LOV-domain chromophore's electronic structures, understanding the structural changes in the protein moiety, particularly regarding light-induced dimerization, remains challenging. Here, we utilize time-resolved X-ray liquidography to capture the light-induced dimerization of Avena sativa LOV2.

Three-Dimensional Integrated Synaptic Devices Based on a Silver-Cluster Conduction Mechanism with High Thermostability.

During the operation of synaptic devices based on traditional conductive filament (CF) models, the formation and dissolution of CFs are usually uncertain. Moreover, when the device is operated for a long time, the CFs may dissolve due to both the Joule heat generated by the device itself and the thermal coupling between the devices. These problems seriously reduce the reliability and stability of the synaptic device.
