Although zygospore (mature zygote) formation in P. blakeslleeanus occurs in liquid glucoseglutamate medium, morphological observations are made more easily when cultures are grown on 1-mm-thick agar medium. Zygophores (sexually differentiated hyphae) develop prior to physical contact in crosses of (plus) and (minus) wild types. Zygophores interlock upon contact and then undergo six successive m...

The relationship between regional blood flow and epicardial S-T segment elevation was studied in 26 open-chest anesthetized dogs with left anterior coronary artery ligations. Changes in myocardial blood flow, measured with 15 plus or minus 5mu (diameter) microspheres labeled with 141-Ce, 85-Sr, and 169-Yb, were correlated with summated S-T segment elevations 15 minutes, 1 hour, and 2 hours afte...

The biochemistry of the lead histochemical technique for demonstrating adenylate cyclase was studied. The enzyme activity of fat cell plasma membranes, using 5'-adenylyl-imidodiphosphate (AMP-PNP) as substrate, was completely inhibited at 1 times 10- minus 4 M Pb(NO3)2 and yet at 4 times 10- minus 3 M Pb(NO3)2 precipitate could be demonstrated by electron microscopy on both sides of plasma memb...

T. minus L.is a complex species which has been divided into three varieties in Turkey.These are var.minus, var.majus (Crantz) Crepin and var. microphyllum Boiss. In this study, stem and leaf anatomial features of the varietieswere described, compared andsome differences have been determined in between the varieties.In transverse sections of stems;the shape of stems, presence or absence of trich...

Deep convolutional neural networks (CNNs) have had a major impact in most areas of image understanding, including object category detection. In object detection, methods such as R-CNN have obtained excellent results by integrating CNNs with region proposal generation algorithms such as selective search. In this paper, we investigate the role of proposal generation in CNN-based detectors in orde...

A number of French colleagues, including me, have seen a drop in funding from our fellow institutions of 10% or more this year. It came as a surprise given how loud were the voices announcing that Science would be a national priority. But this 10% syndroma should not be restricted to money. As my own research projects are dedicated to a family of unusual nucleic acid structures called Gquadrupl...

The effect of digoxin on atrioventricular (a-v) conduction was compared in five patients with an intact cardiac autonomic nervous system (Group I) and seven patients who had undergone cardiac transplantation (Group II), in whom we have previously shown the transplanted heart to be completely denervated. Small decreases in the atrial effective refractory period (ERP) (from 262 plus or minus 12 t...
