Making Family Planning Services Relevant to Adolescents: Perspectives from Rural Communities in Central Ghana

Open Journal of Preventive Medicine 2014年第11期4卷 852-859页

In lower middle-income countries like Ghana, it is common to find low contraceptive use among adolescents with corresponding high pregnancy outcomes. Evidence points to the fact that the use of contraceptives prevents maternal, neonatal and infant deaths, but in most lower middle-income countries, socio-cultural practices inhibit adolescents’ use. Ensuring the uptake of family planning among adolescents is deemed a necessary means of reducing maternal, neonatal and infant mor-tality. This manuscript seeks to provide contextually relevant approaches to satisfying family planning needs of adolescents in a population lacking it. We employed a qualitative study design from an interpretive paradigm with phenomenology as the methodology to understand societal attitudes towards family planning delivery to adolescents, so as to arrive at contextually appro-priate ways of providing family planning to this needy group. Focused group discussions and in-depth interviews techniques were used in data collection among adolescents, relevant commu-nity opinion leaders and family planning & health services providers. Themes that emerged from data analysis with respect to “perspectives on family planning care delivery to adolescents” and “best ways in addressing adolescents’ family planning needs” are presented, followed by discussion of the issues emerging. A significant and encouraging finding of the study was that opinion leaders and healthcare providers viewed family planning as a means of protecting adolescents against pregnancies and their complications. A key recommendation is for policy makers and political leaders to enact legislations that enable adolescents to have friendly family planning service delivery in all places and at all times.

Evolutionary implications of deception in mimicry and masquerade

引用

Current Zoology 2014年第1期60卷 6-15页

作者： Ximena J. nelson School of Biological Sciences University of Canterbury Private Bag 4800 Christchurch New Zealand

Aggressive mimicry occurs when an organism resembles some aspect of another organism （the model） in order to obtain prey through its deceptive resemblance. This may function either through the overt response of the receiver or through the lack of response of the receiver. Reviewing selected examples, I discuss some of the difficulties in ascribing a model for the mimic. I also discuss how a single animal can have multiple ploys in its armoury of deceptive signals, thus belonging within two or more categories of deceptive signalling. In addition to aggressive mimicry, these may include crypsis or camouflage, mas- querade （mimicry of inanimate objects）, and Batesian or protective mimicry. Each of these examples of deception has multiple evolutionary pathways, and some deceptive signals may be more costly to receivers than others, but no single organism is subject to a single selection pressure, leading to the reality that many evolutionary pathways contribute to the diversity we see around us. New technologies are opening new channels of investigation into deceptive signaling in many different sensory modalities, and this is reflected in the recent increase in studies investigating the structure and function of deceptive signals. In turn, these studies are beginning to expose the fascinating complexity of deceptive signaling systems, allowing us to discover the myriad, non-mutually exclusive, solutions that can be selected for to obtain prey

Perspectives on the clinical management ocalized prostate cancer

Asian Journal of Andrology 2014年第4期16卷 511-514页

作者： Joel B nelson Department of Urology University of Pittsburgh School of Medicine Pittsburgh Pennsylvania USA.

Defined broadly, prostate cancer has two states： An indolent histologicalmanifestation of a locally proliferative and invasive process or a clinically relevant, potentially lethal disease. Likewise, the management of clinically localized prostate cancer must address two questions： what sort of disease is this and what needs to be done.

Carboxylesterases in lipid metabolism： From mouse to human

引用

Protein & Cell 2018年第2期9卷 178-195页

作者： Jihong Lian Randal nelson Richard Lehner Group on Molecular and Cell Biology of Lipids University of Alberta Edmonton Alberta Canada Department of Pediatrics University of Alberta Edmonton Alberta Canada Department of Cell Biology University of Alberta Edmonton Alberta Canada

Mammalian carboxylesterases hydrolyze a wide range of xenobiotic and endogenous compounds, including lipid esters. Physiological functions of car- boxylesterases in lipid metabolism and energy home- ostasis in vivo have been demonstrated by genetic manipulations and chemical inhibition in mice, and in vitro through （over）expression, knockdown of expression, and chemical inhibition in a variety of cells. Recent research advances have revealed the relevance of carboxylesterases to metabolic diseases such as obesity and fatty liver disease, suggesting these enzymes might be potential targets for treatment of metabolic disorders. In order to translate pre-clinical studies in cellular and mouse models to humans, dif- ferences and similarities of carboxylesterases between mice and human need to be elucidated. This review presents and discusses the research progress in structure and function of mouse and human car- boxylesterases, and the role of these enzymes in lipid metabolism and metabolic disorders.
