The taxon Tardigrada, commonly called "water bears", consists of microscopic, eight-legged invertebrates that are well known for their ability to tolerate extreme environmental conditions. Their miniscule body size means that tardigrades possess a small total number of cells, the number and arrangement of which may be highly conserved in some organs. Although mitoses have been observed in several organs, the rate and pattern of cell divisions in adult tardigrades has never been characterized. In this study, we incubated live tardigrades over a period of several days with a thymidine analog in order to visualize all cells that had divided during this time...

The corn leafhopper, Dalbulus maidis, which is one of the most important vectors of maize diseases, had the morphology of its spermatozoa described more than 40 years ago. However, the description is imprecise, requiring certain rectifications. Hence, we re-describe the sperm morphology of this species using light microscopy and transmission electron microscopy. Their spermatozoa measured from 118.1 to 128.5 μm in length, this value being about three times smaller than what was previously described. The head region is formed by a small acrosome and the nucleus...

Karyopherin β1 (Kpnβ1), also known as importin-β, is part of the karyopherin superfamily of nuclear transport proteins. Kpnβ1 is an oncogene that is overexpressed in various human cancers. Recent studies have showed that Kpnβ1 is one of the leading causes of cancer-related deaths in the world. However, the role of Kpnβ1 in non-small cell lung cancer (NSCLC) remains uncertain. In this study, we used western blotting to show that Kpnβ1 expression is higher in lung-cancer tissues and cells, and immunohistochemistry analysis revealed that Kpnβ1 was significantly associated with the clinicopathological features of NSCLC...

We studied the effect of alcohol on the pineal gland of 48 male Wistar rats. Animals were divided into control and experimental groups. The experimental group underwent a previous progressive alcoholisation period with ethanol diluted in water at a concentration of 40%. Animals were sacrificed at 3, 6, 9 and 12 months, and the ultrastructure, karyometric indices, and number of synaptic bodies in the pineal gland were analysed. The results showed progressive morphologic alterations in the ethanol-treated animals, which culminated in fatty degeneration of the pineal parenchyma after 6 months...

INTRODUCTION: Ethanol exposure to developing brain may alter the growth and differentiation of neurological cells resulting in unfavorable pathologies. Earlier studies have provided very limited mechanistic insights of cellular and molecular mechanisms which do not mimic with human situation due to varying cell types and poses potential challenges for investigation. Therefore, the present study was undertaken to evaluate the role of ABC transporters and heat shock proteins mediated response in human neural precursor cells (NPCs) and its lineages during proliferation and lineage differentiation against ethanol exposure...

In middle and old age, Alzheimer's disease (AD) is a progressive neurodegenerative disorder of brain. As an increasingly aging population, AD represents a huge burden for the patients' family and the country. However, current therapeutical strategies have shown limited effectiveness. Allicin, which is the main composition of garlic, was reported to prevent the learning and memory impairment of AD mouse model. As the mechanism is not clear, in this study, we used the APP (amyloid precursor protein)/PS1 (presenilin 1) double transgenic mice, which express human mutant APP and PS1, to determine the protective effect of allicin on neurons...

Treatment of massive bone defects is one of the most difficult problems to solve in orthopedics. At present, there is no consensus on the best way to resolve these problems. The aim of our study was to evaluate the effect of a three-dimensional bioimplant over massive bone defects, and to analyse if it improves the speed and quality of integration in recipient bone compared to allograft treatment. Fifteen female lambs with massive bone defects, surgically created in their tibias, were randomly divided into three groups of five lambs each: Group I -treated with the bioimplant; Group 2 -treated with the bioimplant plus nucleated cells of autologous bone marrow; Group 3 -treated with a frozen allograft...

The center of tumors, stem cell niches and mucosal surfaces all represent areas of the body that are reported to be anoxic. However, long-term study of anoxic cell physiology is hindered by the lack of a sustainable method permitting cell cultivation in the complete absence of oxygen. A novel methodology was developed that enabled anoxic cell cultivation (17d maximum time tested) and cell passage. In the absence of oxygen, cell morphology is significantly altered. All cells tested exhibited morphologic changes, i...
