Earth's climate has been dominated by ~100-kyr glacial cycles over the past ~800 ka, yet the mechanism remains debated. Here, we present correlation analyses of spectral power ratios of global records spanning the past 2.7 Ma, revealing a persistent anticorrelation between ~21-kyr and ~100-kyr power ratios, but no significant relationship between ~41-kyr and ~100-kyr power ratios.

During the last glacial period, the iconic Greenland ice-core records provide evidence of interstadial warmings with various durations ranging from a century to millennia. However, whether differences in interstadial duration are mirrored by distinct hydroclimate responses in the tropics remains unclear. Here we present four speleothem δO records from the Indian summer monsoon (ISM) and East Asian summer monsoon (EASM) regions, spanning both short and long interstadials during the last glacial period.

Speleothem δO records from central southern China have long been regarded as a key benchmark for Asian summer monsoon intensity. However, the similar δO minima observed among precession minima and their link to seasonal precipitation mixing remains unclear. Here, we present a 400,000-y record of summer precipitation δO from loess microcodium, which captures distinct precession cycles similar to those seen in speleothem δO records, particularly during glacial periods.

Disentangling anthropogenic from natural induced changes is difficult, but crucial to accurately assess the specific environmental impacts of humans' actions versus climate in the paleoclimate records. Here we combine a new set of proxies, including stable isotopes, element concentrations (mainly Mg, Sr, and U), and detailed mineralogy to better distinguish the impacts of these two factors in the stalagmite records. We studied the period between 1680 and 1860 CE because of the known historical events in Madagascar history (e.

The detailed anatomy of Termination I (TI) is well depicted, but whether changes across Termination II (TII) resemble TI remains controversial. Here we present high-resolution Asian monsoon records covering TII using Shima Cave stalagmites from China. Correlating marine and ice-core records to our U/Th-dated records via millennial-scale variabilities, we find an initial CO rise from 139 ± 1 ka BP concordant with boreal summer insolation increase, which was followed by a major rise phase of CO between 135.

The aim of this study was to explore the prognostic value of mean corpuscular volume (MCV) in newly diagnosed aplastic anemia (AA) patients treated with cyclosporine A (CsA) plus androgen or CsA alone. The clinical data of 181 newly diagnosed patients with aplastic anemia from April 2008 to September 2020 in the Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. According to the MCV levels, the patients were divided into a high-MCV group (107/181) and a normal-MCV group (74/181).

Background: In recent years, chimeric antigen receptor (CAR)-T cell therapy has achieved tremendous efficacy in relapsed/refractory multiple myeloma (R/R MM). However, the impact of antibiotic (ATB) use on R/R MM patients treated with CAR-T is still not known. The aim of our study was to analyse the influence of ATB on the clinical outcomes of R/R MM patients treated with CAR-T cells.

Background: For patients with multiple myeloma progression after anti-BCMA chimeric antigen receptor (CAR) T-cell therapy, the optimal salvage treatment strategies remain unclear. GPRC5D-directed CAR T cell might be a potential option. The aim of this trial was to investigate the activity and safety of anti-GPRC5D CAR T cells in patients with progressive multiple myeloma after anti-BCMA CAR T-cell therapy.

Background: Mitochondrial oxidative stress (ROS) is a crucial factor in the pathogenesis of dilated cardiomyopathy (DCM). Despite its significance, robust biomarkers for assessing its role remain scarce. This study investigates ROS mechanisms in DCM and identifies associated biomarkers, offering fresh insights into diagnosis and treatment.

Statement Of Translational Relevance: Effects of metachronous primary malignant solid tumor (MPMST) on survival risk and prognosis of multiple myeloma (MM) and differences between MPMST occurring before and after MM remains unclear. Use of well-characterized clinical information of individual patient, we found that older patients with MM (≥ 65 years) had a higher risk of developing MPMST. Patients with MM and MPMST including male patients, aged ≥ 65 years and those with ISS stage III had a worse prognosis.

Brain organoids have been proposed as suitable human brain model candidates for a variety of applications. However, the lack of appropriate maturation limits the transferability of such functional tools. Here, we present a method to facilitate neuronal maturation by integrating astrocyte-secreted factors into hPSC-derived 2D and 3D neural culture systems.

G protein-coupled receptor, class C, group 5, member D (GPRC5D) has emerged as a novel target for chimeric antigen receptor (CAR) T-cell therapy, demonstrating promising efficacy in multiple myeloma (MM). However, disease relapse is still common, and the mechanism of resistance remains poorly understood. In this study, we conducted whole-genome sequencing and whole-genome bisulfite sequencing on MM samples from 10 patients who relapsed after GPRC5D CAR T-cell therapy.

Factors associated with outcomes of chimeric antigen receptor (CAR)-T cell therapy in patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) have not been fully elucidated. We explored the impact of the prelymphodepletion (pre-LD) lymphocyte to monocyte ratio (LMR) and its ratio to lactate dehydrogenase (LDH) (LMR/LDH) on the efficacy and prognosis of 60 patients with R/R DLBCL undergoing CAR-T cell therapy. The optimal cutoff values for pre-LD LMR and LMR/LDH were 3.

The frequent droughts and floods, closely associated with the Asian summer monsoon (ASM), has profoundly affected the ecological environment and economy in East Asia. While changes in the ASM are closely related to precipitation patterns, the specific mechanism still requires further investigation. This study utilized stalagmite records from the Feilong Cave in southwest China to reconstruct the evolution of the ASM since the Medieval Warm Period (MWP).

The Asian summer monsoon (ASM) is an important component of the global climate system. Cave oxygen isotope (δO) records from the region have well characterized the ASM millennial-scale climate variability (MCV) over the last 640 ka, with especially detailed insights for the most recent 60 ka, but little is known about ASM variability beyond the U-Th dating limit of ∼640 ka. Furthermore, questions remain regarding the climatic significance of millennial-scale ASM variability recorded among various climate archives, particularly in the context of the "orbital-scale paradox".

Given growing concerns about global climate change, it is critical to understand both historical and current shifts in the hydroclimate, particularly in regions critically entwined with global circulation. The Tibetan Plateau, the Earth's largest and highest plateau, is a nexus for global atmospheric processes, significantly influencing East Asian hydroclimate dynamics through the synergy of the Asian Monsoon and the Westerlies. Yet, understanding historical and recent hydroclimate fluctuations and their wide-ranging ecological and societal consequences remains challenging due to short instrumental observations and partly ambiguous proxy reconstructions.

Article Synopsis
  • The traditional orbital monsoon hypothesis explains rainfall variations in monsoonal regions primarily through local summer insolation over long time scales, notably seen in Asian and South American records.
  • However, some tropical areas show rainfall patterns that don't align with this hypothesis, prompting the exploration of other influencing factors.
  • The study presents a 140,000-year Central American rainfall record from stalagmites, suggesting that the Atlantic Ocean's thermal state and the meridional overturning circulation (AMOC) are key drivers of monsoon changes, rather than just local insolation.
