Breeding Systems in Cortaderia (Gramineae) [PDF]

open access: yesEvolution, 1973
Male sterility has long been known in the grass genus Cortaderia and the species have traditionally been described as dioecious (Stapf, 1897; Pilger, 1906; Hitchcock, 1927; Conert, 1961). However, Connor and Penny (1960) described gynodioecism in one New Zealand species, and it was later shown that all New Zealand Cortaderias are gynodioecious, as well

T2* Magnetic Resonance Imaging Uncovers Hemosiderin Burden in Pediatric Hemophilia: A Call for Sensitive Imaging Biomarkers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hemophilic arthropathy remains the leading morbidity in hemophilia despite modern prophylaxis, and early joint damage may be missed by routine exams. This study explored T2* MRI as a noninvasive biomarker of hemosiderin deposition in pediatric hemophilia.

Childhood Acute Lymphoblastic Leukemia Survival in Western Kenya: Reduction in Early Deaths and Treatment Abandonment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background An earlier study on children diagnosed with acute lymphoblastic leukemia (ALL) at Moi Teaching and Referral Hospital (MTRH) in Kenya reported a low event‐free survival (EFS), excess treatment abandonment, and high induction mortality.

ASSIST: Refinement of a Benefits Navigator Intervention Among Low‐Income Pediatric Oncology Families

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Children with cancer living in poverty experience worse survival and quality of life. Interventions connecting low‐income families to benefits (e.g., Supplemental Nutrition Assistance Program [SNAP] improve health outcomes; yet nearly 50% of SNAP‐eligible pediatric oncology families are unenrolled.

Not Only Hummingbirds: Reproductive Biology and Pollinators of the High-Andean Endangered Puya raimondii (Bromeliaceae)

open access: yesInternational Journal of Plant Biology
Puya raimondii, an endangered high-Andean species, exhibits life-history traits that may strongly influence its reproductive strategy; however, its reproductive biology remains poorly understood. Here, we assessed its floral biology, breeding system, and

BREEDING SYSTEM POLYMORPHISM IN A HETEROSTYLOUS SPECIES [PDF]

open access: yesEvolution, 1976
Heterostylous breeding systems have been the subject of continued interest since the work of Hildebrand (1866, 1871, 1887) and Darwin (1865, 1877) revealed the association of floral heteromorphism with an incompatibility system enforcing outcrossing.

Virtual Plants Need Water Too: Functional-Structural Root System Models in the Context of Drought Tolerance Breeding

open access: yesFrontiers in Plant Science, 2017
Developing a sustainable agricultural model is one of the great challenges of the coming years. The agricultural practices inherited from the Green Revolution of the 1960s show their limits today, and new paradigms need to be explored to counter rising ...

Misperception of Body Weight After Childhood Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Misperception of body weight can negatively impact the weight management efforts of childhood cancer survivors (CCSs). Both being overweight or underweight are associated with chronic health conditions commonly observed in CCS; therefore, accurate weight perception is critical for reducing long‐term health risks.
