Bone Marrow Fat and Hematopoiesis.

Bone marrow fat cells comprise the largest population of cells in the bone marrow cavity, a characteristic that has attracted the attention of scholars from different disciplines. The perception that bone marrow adipocytes are "inert space fillers" has been broken, and currently, bone marrow fat is unanimously considered to be the third largest fat depot, after subcutaneous fat and visceral fat. B...

Multiplexed CRISPR/Cas9-mediated knockout of 19 Fanconi anemia pathway genes in zebrafish revealed their roles in growth, sexual development and fertility.

Fanconi Anemia (FA) is a genomic instability syndrome resulting in aplastic anemia, developmental abnormalities, and predisposition to hematological and other solid organ malignancies. Mutations in genes that encode proteins of the FA pathway fail to orchestrate the repair of DNA damage caused by DNA interstrand crosslinks. Zebrafish harbor homologs for nearly all known FA genes. We used multiplex...

NK cells suppress CD8 T cell immunity via NKG2D in severe aplastic anemia.

The roles of natural killer (NK) cells in shaping the immune system had raised wide interests. Here we intended to explore the regulatory functions of NK cells on CD8 T cells in severe aplastic anemia (SAA) using human participants and lymphocyte infusion-induced bone marrow failure (BMF) mouse model. In SAA patients, NK cells had over-expressions of NKG2D and NKp46, under-expression of NKG2A and ...

Iron deficiency and anemia in patients with inherited bleeding disorders.

Patients with inherited bleeding disorders are predisposed to acute and chronic blood loss, which places them at high risk of iron deficiency anemia (IDA). The clinical effects of iron deficiency (ID) and IDA in the general population are significant and include low energy, reduced cardiovascular health, impaired cognition and reduced health-related quality of life. However, the incidence and impa...

Traumatic penile pseudoaneurysm after straddle injury presenting with life threatening anemia: A unique case and a diagnostic challenge.

Partial urethral disruption after blunt perineal trauma can be initially managed with urethral catheterization. Lower urinary tract symptoms after catheter removal should raise suspicion for urethral stricture and requires further investigation. Lesser known complications require high index of suspicion to prevent life threatening sequelae. In this report, we describe a case of blunt perineal trau...

Effect of salidroside on bone marrow haematopoiesis in a mouse model of myelosuppressed anaemia.

This study was designed to investigate the effect of salidroside (SAL) on bone marrow haematopoiesis in a mouse model of myelosuppressed anemia. After the mouse model was established by 60Co γ irradiation and cyclophosphamide, pancytopenia and a sharp reduction in bone marrow stromal cells and bone marrow haematopoietic stem cells (lineage-Sca1+c-kit+) were observed. This was greatly alleviated b...

Prevalence of anemia and associated risk factors among pregnant women in Lahore, Pakistan.

Maternal anemia is a frequent problem during pregnancy, especially in developing countries, such as Pakistan. In this context, the present study was conducted to determine factors associated with maternal anemia prevalent among women of different age groups visiting different hospitals in Lahore from February to April 2017. The current study used a cross-sectional design involving 390 pregnant wom...

Molecular detection of vector borne pathogens in anemic and thrombocytopenic dogs in southern Brazil.

Arthropod-borne pathogens are medically important because of their ability to cause diseases in their hosts. The purpose of this study was to detect the occurrence of Ehrlichia spp., piroplasmids and Hepatozoon spp. in dogs with anemia and thrombocytopenia in southern Brazil. EDTA-whole blood was collected from 75 domestic dogs presenting anemia or/and thrombocytopenia from Guarapuava, state of Pa...

Is there an association between vitamin D level and iron deficiency in children?

Vitamin D (VitD) affects the erythropoiesis. The aim of this study was to evaluate the association between maternal/child 25-OH VitD (25-OHD) levels and iron deficiency (ID) and anemia (IDA) in children aged 6 months-5 years.

Pharmacological inhibition of prolyl hydroxylase protects against inflammation-induced anemia via efficient erythropoiesis and hepcidin downregulation.

Chronic inflammatory diseases are often associated with anemia. In such conditions, anemia is generally treated with erythropoiesis stimulating agents (ESAs) which are associated with potentially hazardous side effects and poor outcomes. Suboptimal erythropoiesis in chronic inflammation is believed to be caused by elevated hepcidin levels, which causes blockade of iron in tissue stores. In the cur...

3-Monochloropropane-1, 2-diol causes irreversible damage to reproductive ability independent of hormone changes in adult male rats.

3-MCPD, a contaminant frequently detected in foodstuffs, has been reported to damage human kidneys and testes. Previous studies can be used to evaluate the risk to humans of exposure to excessive 3-MCPD for a short period. However, the effects of withdrawal after 3-MCPD exposure have rarely been studied. Adult male SD rats were orally administered 0, 36 and 72 mg 3-MCPD/kg b.w./day for 4 weeks, ...
