Virtually all mRNAs acquire a poly(A) tail co-transcriptionally, but its length is dynamically regulated in the cytoplasm in a transcript-specific manner. The length of the poly(A) tail plays a crucial role in determining mRNA translation, stability, and localization. This dynamic regulation of poly(A) tail length is widely used to create post-transcriptional gene expression programs, allowing for precise temporal and spatial control.

Current analyses predominantly focus on identifying outliers in single genes that can be attributed to cis-acting variants within the gene locus. This approach overlooks causal variants with trans-acting effects on splicing transcriptome-wide, such as variants impacting spliceosome function.

Our previous efforts led to the discovery of a lead compound designated as NAT, a potent centrally acting MOR modulator. However, the fact that NAT precipitated considerable withdrawal effects at higher doses largely impaired its further development.

Imaging findings, of a 9 cm lobulated mass with heterogeneous enhancement on MRI, were unspecific and malignancy could not be excluded. Histological examination of the specimen revealed a well-demarcated tumor composed of Schwann cells and ganglion cells, confirming the diagnosis.

In the Caribbean and Latin America, nearly 17,000 tons of plastic waste are generated and trashed daily in open dumpsites with attendant consequences for the environment, the economy, aquatic life, the beauty of sea beaches, and public health. The increased use of plastics threatens public health and the ecosystem.

Methods: We report two cases of ibrutinib-related uveitis using CARE guidelines and review the cases reported in the literature.
Results: Case 1) A 55-year-old female with recurrent primary central nervous system lymphoma presented with bilateral decreased visual acuity, photophobia, and floaters that started one month after initiating oral treatment with ibrutinib.
Context: Students of color in the United States experience elevated stress across the entire spectrum of education, spanning from early stages of K-12 to the more advanced stages of postgraduate studies. This sustained state of chronic stress decreases learning and curtails opportunities, especially in science, technology, engineering, and math (ST EM) fields, where stress levels are considered exceptionally high. Mindfulness-based practices such as MBSR have a proven effective for stress reduction in college students.

To acquire evidence on its causal role, we developed a new mouse strain carrying an equivalent variant in , the mouse orthologue of .
Design: We used CRISPR/Cas9 to introduce a 707bp deletion in encompassing exon 6 ( ).
Industrial process optimization and control is crucial to increase economic and ecologic efficiency. However, data sovereignty, differing goals, or the required expert knowledge for implementation impede holistic implementation. Further, the increasing use of data-driven AI-methods in process models and industrial sensory often requires regular fine-tuning to accommodate distribution drifts.

Objective: This study assessed the diagnostic accuracy of two WHO clinical and laboratory organ dysfunction markers for determining the best cutoff values in a Latin American setting.
Methods: A prospective multicenter cohort study was conducted in five Latin American countries.
The standard of care for patients with operable gastric adenocarcinoma is perioperative chemotherapy and surgical resection. The deficient mismatch repair (dMMR)/microsatellite instability (MSI-H) phenotype is a major predictive biomarker for immune checkpoint inhibitors (ICIs) efficacy in advanced disease. Several phase II and III trials suggest a promising future role of immunotherapy with or without chemotherapy in the neoadjuvant/adjuvant setting, especially in MSI-H localized gastric adenocarcinomas.

DECT shows profound capabilities to improve diagnosis based on its superior material differentiation and its quantitative value. However, the potential of dual-energy imaging remains relatively untapped, possibly due to its intricate workflow and the intrinsic technical limitations of DECT.

This study focuses on the implementation of a stream sampler to develop a near infrared (NIR) calibration model for blend uniformity monitoring in a continuous manufacturing mixing process. Feeding and mixing characterizations were performed for three loss-in-weight feeders and a commercial continuous mixer to prepare powder blends of 2.

Antenatal thrombosis and inherited thrombophilia have been suggested as causes of IVCA. However, there is little evidence on the clinical course and management of this condition.

Via a feasible and multidimensional approach with basic parameters, we aimed to evaluate the effect of host response at admission on severity stratification in COVID-19 and community-acquired pneumonia (CAP). Three COVID-19 and one CAP multicenter cohorts including hospitalized patients were recruited.

Thus, it is imperative for basic research to develop novel and nonaddictive pain medications. Toward addressing this clinical goal, nalfurafine (NLF) was chosen as a lead and its structure-activity relationship (SAR) systematically studied through design, syntheses, and characterization of 24 analogues.

The DELICIOUS project aims to promote healthy lifestyles among children and adolescents by implementing activities and tools to increase the adherence to the Mediterranean Diet with an attention to the environmental impacts of the diet. This study protocol describes the DELICIOUS project as a single-arm, uncontrolled behavioural intervention providing formal and non-formal education activities, development of new snacks and recipe reformulation, web/mobile app development, and physical activities to school children and adolescents in five European countries.
