The role Hiwi gene in the maintenance of lung cancer stem cell populations

Neoplasma, 2013
The Piwi family genes are highly conserved during evolution and play essential roles in stem cell self-renewal in diverse organisms. However, data on the function of Hiwi gene (a human homologue of Piwi family) in cancer stem cells remains obscure. The aim of this study was to investigate the role of Hiwi gene in the lung cancer stem cells.

HiWi Project: High Efficiency Electric Drives

2015
Vehicles develop their highest efficiency of around 93–95 % within a speed range of usually 1/4 to 1/3 of the maximum, whereas in real-life driving cycles the motor operates at a wider range of speeds and at partial load, resulting in much lower efficiency.

Food Transfers Among Hiwi Foragers of Venezuela: Tests of Reciprocity

Human Ecology, 2000
Although food sharing has been observed in many traditional societies, we still do not have a deep understanding of how various ecological conditions produce variation in who gives and who receives specific resources. To understand better the behavioral ecology of food sharing, we present data collected with the Hiwi of Venezuela and focus on two ...

Early dry season subsistence ecology of Cuiva (Hiwi) foragers of Venezuela

Human Ecology, 1987
The subsistence ecology of Venezuelan Cuiva foragers during the early dry season is described. Data on diet, time allocation, demography, and physical measurements are presented. Analyses show that the Cuiva depend primarily on game and wild roots during the early dry season for their subsistence.

Overexpression of Hiwi Inhibits the Growth and Migration of Chronic Myeloid Leukemia Cells

Cell Biochemistry and Biophysics, 2015
Chronic myeloid leukemia (CML) is a hematopoietic malignancy characterized by dysregulated growth and proliferation of hematopoietic stem/progenitor cells in bone marrow and excessive expansion of hematopoietic compartments in peripheral blood. Expression deletion of Hiwi, a human Piwi homolog, has been reported to be implicated in leukemogenesis.

Trade-Offs between female food acquisition and child care among hiwi and ache foragers

Human Nature, 1992
Even though female food acquisition is an area of considerable interest in hunter-gatherer research, the ecological determinants of women's economic decisions in these populations are still poorly understood. The literature on female foraging behavior indicates that there is considerable variation within and across foraging societies in the amount of ...

Overexpression of Argonaute HIWI Gene in Colorectal Cancer Stem Cells and Colorectal Cancerous Tissue

Iranian Red Crescent Medical Journal, 2023
Background: Post-treatment nursing care is essential for patients with venous malformations (VMs) after they have undergone treatment. Effective post-treatment nursing care requires adequate resources, effective communication, patient compliance, and addressing psychological distress. However, the clinical care plan for VMs in the pharyngeal isthmus is

Reciprocal altruism and food sharing decisions among Hiwi and Ache hunter?gatherers

Behavioral Ecology and Sociobiology, 2004
The common occurrence of food transfers within human hunter–gatherer and forager–horticulturalist groups presents exciting test cases for evolutionary models of altruism. While kin biases in sharing are consistent with nepotism based on kin selection, there is much debate over the extent to which reciprocal altruism and tolerated scrounging provide ...
