in this study, for the first time in iran, the karyotype of bigmouth lotak, cyprinion macrostomum heckel, 1843, was investigated through examining metaphase chromosomes of seven fish with mean weight 30±5g caught by electrofishing from godarkhosh river in ilam province. to stimulate cell divisions, fish were injected intraperitoneally two times by phytohemagglutinin (pha). the cell divisions we...

This paper looks at the emergence of divisions of general practice in Australia. Divisions are local groups of general practitioners working to integrate general practice into the wider health system and to explore opportunities for improving service delivery, teaching and research. There are now 116 divisions of general practice, covering over 95 per cent of the Australian population. Projects...

In this paper, we consider a dynamic model in which a firm’s headquarters (HQ) allocates the limited capital budget into two divisions which are privately informed of their investment opportunities, having an overstating incentive. The vertical communication between HQ and each division is based on a contract, while the horizontal communication between divisions is collusive to overstate. The m...

Cleavage plane orientation has been thought to govern the fate of neural stem cell progeny, but supporting evidence in the neocortex has been sparse. A new study by Postiglione et al. in this issue of Neuron shows that mouse Inscuteable-mediated control of cleavage plane orientation regulates the output of neural progenitor cells.

25 Objective: We compared the flow rates, reactivity and morphology of the distal Internal Thoracic Artery 26 (ITA) and its branches, the Superior Epigastric (SE) and Musculophrenic (MP) arteries to test their 27 applicability as possible conduits in coronary artery bypass grafting (CABG) surgeries. 28 Methods: Skeletonized ITA and sub-divisions of patients undergoing CABG were studied 29 intra...

Two-photon excitation microscopy was used to reconstruct cell divisions in living zebrafish embryonic retinas. Contrary to proposed models for vertebrate asymmetric divisions, no apico-basal cell divisions take place in the zebrafish retina during the generation of postmitotic neurons. However, a surprising shift in the orientation of cell division from central-peripheral to circumferential occ...

Stem cells are thought to balance self-renewal and differentiation through asymmetric and symmetric divisions, but whether such divisions occur during hematopoietic development remains unknown. Using a Notch reporter mouse, in which GFP acts as a sensor for differentiation, we image hematopoietic precursors and show that they undergo both symmetric and asymmetric divisions. In addition we show ...

A multi-divisional firm can engage in ”winner-picking” to redistribute scarce funds efficiently across divisions. But there is a conflict between rewarding winners (investing) and producing resources with which to reward winners (incentives). Managers in winning divisions are tempted to free-ride on resources produced by managers in loosing divisions whose incentives to produce resources, antic...

BACKGROUND Recent years have seen an increasing corporatization of general practice. OBJECTIVE This paper considers how divisions of general practice should respond to the corporatization of general practice. DISCUSSION Corporate models are an economically rational outcome of structural features of Medicare funding for Australian general practice. One limitation of these structures is that ...

Data mining is playing an important role in decision making for business activities and governmental administration. Since many organizations or their divisions do not possess the in-house expertise and infrastructure for data mining, it is beneficial to delegate data mining tasks to external service providers. However, the organizations or divisions may lose of private information during the d...
