Evolutionary patterns of bone histology and bone compactness in xenarthran mammal long bones. [PDF]

open access: yesPLoS ONE, 2013
Bone microstructure reflects physiological characteristics and has been shown to contain phylogenetic and ecological signals. Although mammalian long bone histology is receiving increasing attention, systematic examination of the main clades has not yet ...

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

Induction of hemopoiesis in rat embryonic bone transplanted into adult subcutaneous connective tissue [PDF]

open access: yes, 1978
Five pairs of immature, non-hemopoietic femur and tibia from 17-day-old gestating female rat fetuses, whose sex was determined by chromosomal analysis of liver cells, were transplanted into subcutaneous tissues of adult male rats. The original bones were

Whole Bone Mechanics and Bone Quality [PDF]

open access: yesClinical Orthopaedics & Related Research, 2011
The skeleton plays a critical structural role in bearing functional loads, and failure to do so results in fracture. As we evaluate new therapeutics and consider treatments to prevent skeletal fractures, understanding the basic mechanics underlying whole bone testing and the key principles and characteristics contributing to the structural strength of ...

Bone Marrow Failure as an Underrecognized Feature of KAT6A Syndrome

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT KAT6A syndrome (Arboleda–Tham syndrome) is a rare disorder caused by heterozygous pathogenic variants in KAT6A, a histone acetyltransferase essential for chromatin remodeling and hematopoietic stem cell function. While neurodevelopmental features are well established, hematologic manifestations are underrecognized.

RT‐PCR–Based Detection of Bone Marrow Involvement in Ewing Sarcoma: Diagnostic Validity and Prognostic Relevance

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background In Ewing sarcoma (EwS), metastases, including those to bone marrow (BM), are the main factors influencing prognosis. Although reverse transcription polymerase chain reaction (RT‐PCR) offers greater sensitivity, the current EWING protocol defines BM metastases solely using light microscopic detection.

Histomorphometric analysis of the femoral neck in patients with and without femoral neck fracture [PDF]

open access: yesActa Ortopédica Brasileira, 2015
OBJECTIVE: To determine, through bone histomorphometry in femoral neck, whether there are differences in the cancellous bone of the proximal femur from female patients over 60 years old who had femoral neck fracture and similar patients who did not have ...
