Modifications of microbiome-derived cell-free RNA in plasma discriminates colorectal cancer samples.

Circulating cell-free RNA (cfRNA) in plasma represents a promising avenue for cancer detection. We report low-input multiple methylation sequencing, a method for profiling modification patterns in cfRNA, enabling the detection of diverse transfer RNAs and small noncoding RNAs derived from both the human genome and the microbiome. RNA modification patterns in microbiome-derived cfRNA accurately reflect host microbiota activity and hold potential for the early detection of colorectal cancer.

Compromised efferocytosis during aging is related to COVID-19 severity in mice.

Aging is one of the greatest risk factors for morbidity caused by the coronavirus disease 2019 (COVID-19). In older individuals, a dysregulated immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection contributes to disease severity; however, the underlying mechanism remains elusive. In this study, we established an aging mouse model of COVID-19, successfully replicating the development of a relatively severe disease in older adults.

Methods: This retrospective study analyzed patients with CD and non-functioning pituitary adenomas (NFPAs) who underwent TSS at Massachusetts General Hospital from 2005 to 2019.

Precision aerobic irrigation reduces methane emissions in paddy fields by regulating soil redox potential and root-secreted organic acids.

The effect of water management on methane (CH) emissions from paddy has been well documented, yet the impact of Precision Aerobic Irrigation (PAI) on methanogens and methanotrophs communities, as well as their metabolic types, remain unclear. This study utilized two different irrigation regimes ((continuous flooding (CF) and PAI) to elucidate the impacts of PAI on the community structure and metabolism of methanogens and methanotrophs. The results indicated that PAI significantly reduced irrigation water use by 33.

The associations between multiple indicators of campus green space exposure and college students' mental health before, during, and after the COVID-19 pandemic.

Campus green space (CGS) is the primary natural environment that college students are exposed to. The health benefits from CGS exposure have received widespread attention. However, few studies have compared the mental health benefits brought by different measures of CGS exposure, or investigated temporal disparities in these associations.

Small-molecule-catalysed deamination enables transcriptome-wide profiling of N-methyladenosine in RNA.

The deamination reaction is important to both fundamental organic chemistry and biochemistry. Traditional chemical methods of deamination rely on the use of aryldiazonium salts under harsh acidic conditions, which limits the application scope for most biological substrates. Here we present an N-nitrosation strategy for deamination under mild conditions that DNA and RNA biological macromolecules can tolerate.

One-Hour Oral Glucose Tolerance Test for the Postpartum Reclassification of Women With Hyperglycemia in Pregnancy.

Objective: The International Diabetes Federation recently endorsed a 1-h oral glucose tolerance test (OGTT) as more convenient than the conventional 2-h OGTT. In practice, women with hyperglycemia in pregnancy are advised to undergo a 2-h OGTT within 6 months after delivery, but this test is often not completed, partly owing to its inconvenience for busy mothers. Recognizing the potential advantage of the 1-h OGTT in this setting, we sought to compare 1-h and 2-h OGTT glucose measurements at 3 months postpartum as predictors of dysglycemia (prediabetes/diabetes) over the first 5 years postpartum.

Osmosensor TMEM63B facilitates insulin secretion in pancreatic β-cells.

Elevated glucose metabolism triggers two primary processes that lead to β-cell depolarization and insulin secretion: the closure of ATP-sensitive K channels via ATP-dependent mechanisms and the activation of mechanosensitive channels (MSCs) due to cell swelling. However, the identity of these MSCs remains unclear. In this study, we found that TMEM63B is a stretch-activated cation channel (SAC) crucial for regulating insulin secretion in response to elevated glucose levels.

Quantitative RNA pseudouridine maps reveal multilayered translation control through plant rRNA, tRNA and mRNA pseudouridylation.

Pseudouridine (Ψ) is the most abundant RNA modification, yet studies of Ψ have been hindered by a lack of robust methods to profile comprehensive Ψ maps. Here we utilize bisulfite-induced deletion sequencing to generate transcriptome-wide Ψ maps at single-base resolution across various plant species. Integrating ribosomal RNA, transfer RNA and messenger RNA Ψ stoichiometry with mRNA abundance and polysome profiling data, we uncover a multilayered regulation of translation efficiency through Ψ modifications.

Survival Is Just the Beginning of Recovery: A Qualitative Study of Survivors' Experiences after Severe Injury.

Purpose: Patients experience severe physical trauma every year. However, studies on survivors' experiences after severe injury are limited. Previous studies have mainly focused on time spans of trauma treatment.

A hand-held in-situ nucleic acid detection device based on dual-function GHz acoustofluidic resonator.

Microfluidic-based nucleic acid testing (NAT) has been proven as an alternative approach for in-situ and rapid NA detection. However, these on-chip methods still require complex peripherals, which contradict the purpose of point-of-care (POC) applications. One of the major challenges is the integration of NA purification and amplification in a miniaturized setup with high mass and heat transfer efficiency.

Effects of different doses of tirofiban combined with dual antiplatelet drugs on platelet indices, vascular endothelial function, and major adverse cardiovascular events in patients with acute ST-segment elevated myocardial infarction undergoing percutaneous coronary intervention.

This trial targeted to analyze the effects of different doses of tirofiban combined with dual antiplatelet drugs on platelet indices, vascular endothelial function, and major adverse cardiovascular events (MACE) in patients with acute ST-segment elevated myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). A total of 180 patients with STEMI who underwent PCI were divided into Group A, Group B, and Group C (60 cases per group). Group A was given conventional medication, and Groups B and C were given a standard dose (10 μg/kg) and a high dose (20 μg/kg) of tirofiban on the basis of Group A, respectively.

Unmet needs in cervical cancer - can biological therapies plug the gap?

Introduction: Cervical cancer remains one of the most common gynecologic malignancies worldwide. A disproportionate burden of cases occurs in developing countries due to inadequate screening and treatment. Even among patients adequately treated, in the presence of locally advanced or recurrent disease, outcomes tend to be poor.

A Glycemic Threshold Above Which the Improvement of β-Cell Function and Glycemia in Response to Insulin Therapy Is Amplified in Early Type 2 Diabetes: The Reversal of Glucotoxicity.

Objective: Alleviation of unrecognized glucotoxicity, with resultant recovery of β-cell function, could amplify the glucose-lowering effect of pharmacotherapy and contribute to the variable therapeutic response observed among patients with type 2 diabetes (T2D). However, clinical evidence supporting this concept is lacking. Short-term intensive insulin therapy (IIT) can ameliorate glucotoxicity and improve β-cell function in early T2D.

PTPN2 copper-sensing relays copper level fluctuations into EGFR/CREB activation and associated CTR1 transcriptional repression.

Fluxes in human copper levels recently garnered attention for roles in cellular signaling, including affecting levels of the signaling molecule cyclic adenosine monophosphate. We herein apply an unbiased temporal evaluation of the signaling and whole genome transcriptional activities modulated by copper level fluctuations to identify potential copper sensor proteins responsible for driving these activities. We find that fluctuations in physiologically relevant copper levels modulate EGFR signal transduction and activation of the transcription factor CREB.
