Why Self-fertilizing Plants Still Exist in Wild Populations: Diversity Assurance through Stress-Induced Male Sterility May Promote Selective Outcrossing and Recombination

Agronomy, 2020
Climate change creates challenges for wild species, but plants have survived and adapted to similar changes in their evolutionary past. Most plants were originally outcrossing, one theoretical genetic reason being that self-fertilization does not create ...

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

Quality of maternal and child health services in Tanzanian primary healthcare: a 2021–2022 star rating review

Reproductive Health
Background Tanzania faces high maternal and infant mortality rates, yet key service quality metrics remain underexamined, limiting targeted improvements. Star Rating Assessment (SRA), introduced in 2015, aims to improve primary health care (PHC) quality,

Pollinator-mediated self-pollination and reproductive assurance in an isolated tree of Magnolia grandiflora L.

Ecological Processes, 2020
Background The ability to produce seeds when pollinators or potential mates are scarce is one of the principal advantages of self-pollination in flowering plants.

Pollen Limitation and Reproductive Assurance in the Flora of the Coastal Atacama Desert

International Journal of Plant Sciences, 2010
Pollen limitation (PL) in plant populations is supposed to be particularly strong in variable pollinator environments. Here, we examined the extent of PL in the coastal Atacama Desert, where low and unpredictable rainfall drives large interannual variation in plant cover and pollinator abundances.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Venetoclax‐Based Therapy as a Bridge to Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Pediatric Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.
