The selectivity and specificity of autophagy in drosophila [PDF]

open access: yes, 2012
Autophagy is a process of cellular self-degradation and is a major pathway for elimination of cytoplasmic material by the lysosomes. Autophagy is responsible for the degradation of damaged organelles and protein aggregates and therefore plays a ...

Characterization of a monoclonal antibody that induces the acrosome reaction of sea urchin sperm. [PDF]

open access: yes, 1987
A monoclonal antibody, J18/29, induces the acrosome reaction (AR) in spermatozoa of the sea urchin Strongylocentrotus purpuratus. J18/29 induces increases in both intracellular Ca2+ and intracellular pH similar to those occurring upon induction of the AR

VideoGraph: Recognizing Minutes-Long Human Activities in Videos [PDF]

open access: yes, 2019
Many human activities take minutes to unfold. To represent them, related works opt for statistical pooling, which neglects the temporal structure. Others opt for convolutional methods, as CNN and Non-Local. While successful in learning temporal concepts,

Gabor Filter and Rough Clustering Based Edge Detection

open access: yes, 2014
This paper introduces an efficient edge detection method based on Gabor filter and rough clustering. The input image is smoothed by Gabor function, and the concept of rough clustering is used to focus on edge detection with soft computational approach ...

A novel mechanism for binding of galactose-terminated glycans by the C-type carbohydrate recognition domain in blood dendritic cell antigen 2 [PDF]

open access: yes, 2015
Blood dendritic cell antigen 2 (BDCA-2; also designated CLEC4C or CD303) is uniquely expressed on plasmacytoid dendritic cells. Stimulation of BDCA-2 with antibodies leads to an anti-inflammatory response in these cells, but the natural ligands for the ...

Evidence for inbreeding depression in a species with limited opportunity for maternal effects [PDF]

open access: yes, 2015
It is often assumed that mating with close relatives reduces offspring fitness. In such cases, reduced offspring fitness may arise from inbreeding depression (i.e., genetic effects of elevated homozygosity) or from post-mating maternal investment.

Cell cycle regulation of a Xenopus Wee1-like kinase [PDF]

open access: yes, 1995
Using a polymerase chain reaction-based strategy, we have isolated a gene encoding a Wee1-like kinase from Xenopus eggs. The recombinant Xenopus Wee1 protein efficiently phosphorylates Cdc2 exclusively on Tyr- 15 in a cyclin-dependent manner.

Gamete Recognition and Egg Activation in Sea Urchins [PDF]

open access: yesAmerican Zoologist, 1995
SYNOPSIS. Free-spawning marine invertebrates face the challenge of ensuring that gametes of the same species come into contact, recognize, bind to and fuse with one another once they have been released by the adults. Coordinated spawning, chemoattraction and specific cell-cell recognition events help to overcome this challenge. One marine invertebrate,

Host personality and seasonal parasitism risk do not account for egg rejection behavior in the azure-winged magpie

open access: yesInternational Journal for Parasitology: Parasites and Wildlife
Brood parasitism reduces the reproductive success of hosts and many host birds have evolved a range of anti-parasitism strategies, including egg recognition and egg rejection.

\u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) Reproduction and Development in Scots, Jack, Red and Eastern White Pine Under Laboratory Conditions [PDF]

open access: yes, 2018
The pine shoot beetle, Tomicus piniperda (L.) (Coleoptera: Scolytidae), is an exotic bark beetle in North America that was first found in the Great Lakes region in 1992. We evaluated T.
