Functional rise

The demands for novel and efficient therapies have gradually increased with the rising concerns of osteoporosis (OP). The most popular method in promoting bone regeneration during osteoporotic conditions consists of loading bioactive materials with different drugs to treat osteoporotic bones by either promoting the process of osteogenesis, or by inhibiting the activity of osteoclasts. By analyzing single cell sequencing results, we found that divalent metal transporter 1 (DMT1) played a role in OP. Based on our previous results, we found that melatonin (MT) suppressed expression of DMT1 induced by high glucose during OP, so we determined the efficacy of MT for the treatment of OP...

The retinal ganglion cells (RGCs) receive different combinations of L, M, and S cone inputs and give rise to one achromatic and two chromatic post-receptoral channels. Beyond the retina, RGC outputs are subject to filtering and normalization along the geniculo-striate pathway, ultimately producing the properties of human vision. The goal of the current study was to determine temporal sensitivity across the three post-receptoral channels in subcortical and cortical regions involved in vision. We measured functional magnetic resonance imaging (MRI) responses at 7 Tesla from three participants (two males, one female) viewing a high-contrast, flickering, spatially-uniform wide field (∼140°)...

Autism spectrum disorder (ASD) is a multifactorial, pervasive neurodevelopmental disorder affecting 1 in 36 children in the United States. Given the rising prevalence and significant economic and social costs associated with ASD, it is critical that continued efforts be made towards better understanding the underlying etiology as well as management of the condition and its commonly associated comorbidities. It has been estimated that upwards of 70% of children with ASD have a positive history of gastrointestinal (GI) symptoms...

Osteoarthritis (OA) is a degenerative bone disease associated with aging. The rising global aging population has led to a surge in OA cases, thereby imposing a significant socioeconomic burden. Researchers have been keenly investigating the mechanisms underlying OA. Previous studies have suggested that the disease starts with synovial inflammation and hyperplasia, advancing toward cartilage degradation. Ultimately, subchondral-bone collapse, sclerosis, and osteophyte formation occur. This progression is deemed as "top to bottom...

Levodopa (L-3,4-dihydroxyphenylalanine, L-Dopa) alleviates the symptoms of Parkinson's disease (PD), yet prolonged usage may give rise to severe adverse effects. Resveratrol (RSV) is a potent antioxidant, anticancer and anti-inflammatory agent. And a variety of polyphenol antioxidant compounds derived from RSV combined with levodopa have demonstrated neuroprotective activity against neuronal cell death. The purpose of this study was to examine the impact of this combination of RSV and L-Dopa on the survival rate, growth status, and reactive oxygen species (ROS) of MES23...

The ongoing climate change on the Tibetan Plateau, leading to warming and precipitation anomalies, modifies phosphorus (P) cycling in alpine meadow soils. However, the interactions and cascading effects of warming and precipitation changes on the key "extracellular" and "intracellular" P cycling genes (PCGs) of bacteria are largely unknown for these P-limited ecosystems. We used metagenomics to analyze the individual and combined effects of warming and altered precipitation on soil PCGs and P transformation in a manipulation experiment...

Carbon dots (C-dots) obtained from D-glucose have attracted great interest because of their properties and as a model for understanding the synthesis process and the origin of photoluminescence in carbon-based nanostructures. Synthesising C-dots under hydrothermal conditions has become one of the most common methods for their preparation. Understanding the details of this process is quite difficult. To tackle this challenge, we have adopted a multi-technique approach in our present work. We have correlated different spectroscopic analyses, such as infrared, Raman, fluorescence, NMR, and UV-Vis, to connect the emissions with specific chemical groups...

According to many, we live in "posttruth" times, with the pervasiveness of falsehoods being an existential threat to democracy and the functioning of free societies. Why do people believe and propagate falsehoods? Current accounts focus on psychological deficiencies, heuristic errors, self-enhancing motivations, and motivations to sow chaos. Here, we advance a complementary, outwardly (vs. inwardly) oriented, and ultimate (vs. proximate) account that people often believe and spread falsehoods for socially functional reasons...

In this work, the ultrafast intramolecular rotation behavior of 1,1,2,3,4,5-hexaphenylsilole has been investigated in several solutions with different viscosities using femtosecond transient absorption spectroscopy combined with density functional theory and time-dependent density functional theory calculations. It is demonstrated that the nonradiative process, which competes with radiative decay, involves two main stages, namely the restricted intramolecular rotation and internal conversion processes. The intramolecular rotation depends on viscosity and presents a significant restriction...

Dementia, an increasingly prevalent neurological disorder with a projected threefold rise globally by 2050, necessitates early detection for effective management. The risk notably increases after age 65. Dementia leads to a progressive decline in cognitive functions, affecting memory, reasoning, and problem-solving abilities. This decline can impact the individual's ability to perform daily tasks and make decisions, underscoring the crucial importance of timely identification. With the advent of technologies like computer vision and deep learning, the prospect of early detection becomes even more promising...

As a class of rising electrophilic coupling reagents, aryl-thianthreniums (aryl-TTs) have been gaining immense attention. Herein, a novel palladium-catalyzed domino annulation of aryl-TTs with anhydrides is proposed to rapidly assemble a collection of highly functionalized fluorenones. This finding presents an innovative reaction pattern of aryl-TTs wherein the domino annulation version is first involved. Heavily compared with the existing conversions with aryl-TTs, this identified process successively functions as four aryl C-H bonds...

Both male and female athletes experience acute fatigue and decreased performance from intense training sessions and training cycles with inadequate recovery. The concept of training with insufficient recovery time is known as overtraining syndrome (OTS). Primary stressors leading to OTS include excessive training, environmental factors, and inadequate levels of sleep. Sleep is a critical component of rest, recovery, memory, and cognitive function in collegiate athletes, known as male and female athletes between 18 and 22 years old...

Macromolecular crystallography has historically provided the atomic structures of proteins fundamental to cellular functions. However, the advent of cryo-electron microscopy for structure determination of large and increasingly smaller and flexible proteins signaled a paradigm shift in structural biology. The extensive structural and sequence data from crystallography and advanced sequencing techniques have been pivotal for training computational models for accurate structure prediction, unveiling the general fold of most proteins...

The past decade has witnessed amplified public awareness of age-related dementias. This has resulted in a dramatic rise in the number of older persons referred to memory clinics with a primary complaint of self-reported memory loss without an antecedent neurological event (e.g., stroke) who produce neuropsychological test profiles that lack evidence of such impairment. Since the latter part of the 19th century, a confusing array of changing terminology, criteria, and perceived causation have been ascribed to patients with unverified medical symptoms to implicate psychological causation...

OBJECTIVE: The results of surgical versus conservative treatment of acute Achilles tendon ruptures are still controversial. The objective of this study was to compare surgical and conservative treatment at a minimum follow-up of 1 year in terms of the complications, functional outcomes and clinical results. HYPOTHESES: There is no difference in the complications, clinical results and functional outcomes between the two treatment groups. There is no difference in the occurrence of complications or the clinical results due to the immobilization or rehabilitation protocols...

The transition of bacteria from an individualistic to a biofilm lifestyle profoundly alters their biology. During biofilm development, the bacterial cell-cell adhesions are a major determinant of initial microcolonies, which serve as kernels for the subsequent microscopic and mesoscopic structure of the biofilm, and determine the resulting functionality. In this study, the significance of bacterial cell-cell adhesion dynamics on bacterial aggregation and biofilm maturation is elucidated. Using photoswitchable adhesins between bacteria, modifying the dynamics of bacterial cell-cell adhesions with periodic dark-light cycles is systematic...
