Increased erythropoietin production Increased heart rate Increased cardiac output Enhancement in oxygen extraction The answer for this question is b. increased heart rate. A reduction in tissue oxygenation as happens in anemia stimulates increased production of erythropoietin through a complex feedback mechanism. Increased production of erythropoietin enhances erythropoiesis in anemia. Increased extraction of oxygen in anemia is a compensatory mechanism that is mediated by an increase in 2, 3-diphosphoglycerate concentrations. Increased cardiac output is the main hemodynamic compensatory mechanism in anemia that aims to increase blood flow to the body organs. An increase in heart rate ...

Introduction

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has gained significant popularity as well as extreme attention over the last couple of years due to its benefits and positive attributes. LA-ICP-MS has been extensively used in the analysis of biological samples, chemical samples and gemology. The technique of laser ablation inductively coupled plasma mass spectrometry is a significant technique for quantitative chemical analysis (Becker, 2013). Due to its numerous advantages such as rapid and direct analysis of samples, high sensitivity and high spatial resolution, it has been applied in numerous applications in different fields apart from chemistry. The use ...

IRON SUPPLEMENTATION DURING PREGNANCY

Iron Supplementation during Pregnancy Iron deficiency anemia during pregnancy is a risk factor for adverse maternal and perinatal care. According to the World Health Organization, approximately 56 million pregnant women globally get affected with anemia, which is associated with iron deficiency. The large group of pregnant women affected with iron deficiency are mostly the poor and most vulnerable, especially those living in developing countries like South-east Asia. They have insufficient iron to meet the increased iron needs both for them and the foetus. According to Staff (2013), approximately 29% of the pregnant women experience iron depletion. Iron is vital ...

Introduction

Prenatal iron supplementation has been the customary recommendation in addressing maternal anemia especially in developing countries for over thirty years (West, et al., 2014). There is paucity of information regarding the correspondence between hemoglobin levels in pregnant women and iron supplementation. The limited information in this pertinent public health issue is more pronounced in developing countries as West, et al., (2014) opines. The main purpose of this research is thus to establish the efficacy of prenatal iron supplements on the hemoglobin levels of pregnant women in developing countries.

It has been well documented that Emily Dickinson wrote poetry for herself and her friends, not for publication. Her expression, found in her poetry, is an expression of self, often conflated as thoughts entered her mind from multiple directions creating mature works that bent and formed new visions different and fuller than that original image at the beginning of each poem. Emily Dickinson’s reclusive nature is revealed in much of her poetry. It is in those written lines where she explores her world. Her work, relegated to letters to her friends, was from her soul and not meant ...

Introduction The evil-God challenge is an offshoot of the unending debate over the existence of God on the basis of the problem of evil. In this current presentation, Law simply improved the discourse by enhancing its sophistication through his theory of reverse theodicy and theory of symmetrical logic. However, the persistence of this discourse without conclusive resolution flows from several flaws that will be discussed in adequate detail in Critique section of this paper. The critique will be grounded upon the accepted definitions of ‘evil’ and ‘God’ from the religious tradition of Catholicism, ...
