BTSegDiff: Brain tumor segmentation based on multimodal MRI Dynamically guided diffusion probability model.
Comput Biol Med
January 2025
School of Information Science and Engineering, Yunnan University, 650500, Kunming, China. Electronic address:
In the treatment of brain tumors, accurate diagnosis and treatment heavily rely on reliable brain tumor segmentation, where multimodal Magnetic Resonance Imaging (MRI) plays a pivotal role by providing valuable complementary information. This integration significantly enhances the performance of brain tumor segmentation. However, due to the uneven grayscale distribution, irregular shapes, and significant size variations in brain tumor images, this task remains highly challenging.

Centre for the Studies of Asphyxia and Resuscitation, Neonatal Research Unit, Royal Alexandra Hospital, Edmonton, AB, Canada.
Background: Positive pressure ventilation (PPV) in the delivery room is routinely performed using a face mask attached to a ventilation device. In 2023, the Consensus of Science and Treatment Recommendations for neonatal resuscitation stated that a supraglottic airway (SGA) can be used for PPV if resources and training permits. However, there is very limited data on tidal volume (V) delivery using SGAs.

Int J Emerg Med
January 2025
Division of Emergency Medicine, Boston Children's Hospital, 300 Longwood Ave, Boston, MA, 02115, USA.
Background: Globally, most children seek emergency care at general rather than specialized pediatric emergency departments. There remains significant variation in the provision of pediatric emergency care, particularly in resource-constrained settings. The objective of this study is to pilot a self-assessment tool to evaluate pediatric emergency care capabilities in low- and middle-income country (LMIC) hospitals on the African Continent.

BMC Genomics
January 2025
Sesoko Marine Station, Tropical Biosphere Research Center, University of the Ryukyus, 3422 Sesoko, Motobu, Okinawa, 905-0227, Japan.
Background: Rising seawater temperatures increasingly threaten coral reefs. The ability of coral larvae to withstand heat is crucial for maintaining reef ecosystems. Although several studies have investigated coral larvae's genetic responses to thermal stress, most relied on pooled sample sequencing, which provides population-level insights but may mask individual genotype variability.

January 2025
Bodega Marine Laboratory, University of California, Davis, Bodega Bay, CA, 94923, USA.
Marine foundation species are increasingly impacted by anthropogenic stressors, driving a loss of diversity within these critical habitats. Prior studies suggest that species diversity within mussel beds has declined precipitously in southern California, USA, but it is unclear whether a similar loss has occurred farther north. Here, we resurvey a mussel bed community in northern California first sampled in 1941 to evaluate changes in diversity after 78 years.
