Arabidopsis Qc‑SNARE genes BET11 and BET12 are required for fertility and pollen tube elongation
(2015-10-01)
Pollen tubes are rapidly growing specialized structures that elongate in a polar manner. They play a crucial role in the delivery of sperm cells through the stylar tissues of the flower and into the embryo sac, where the ...
Individual Differences In The Forced Swimming Test And The Effect Of Environmental Enrichment: Searching For An Interaction
(Neuroscience 265(1):95-107, 2014-02-05)
Animals with low and high immobility in the forced
swimming test (FST) differ in a number of neurobehavioral
factors. A growing body of evidence suggests that the exposure
to enriched environments mediates a number ...
Two Groups of Cocirculating, Epidemic Clostridiodes difficile Strains Microdiversify through Different Mechanisms
(2018-03)
Clostridiodes difficile strains from the NAPCR1/ST54 and NAP1/ST01 types have caused outbreaks despite of their notable differences in genome diversity. By comparing whole genome sequences of 32 NAPCR1/ST54 isolates and ...
Effects of a myotoxic phospholipase A2 isolated from Bothrops asper venom on skeletal muscle sarcoplasmic reticulum
(1987)
The myotoxin from B. asper snake venom inhibited Ca-ATPase activity of rabbit sarcoplasmic reticulum after incubation in vitro. Inhibition was non-competitive and albumin enhanced the effect of the toxin. Furthermore, B. ...
Estudio comparativo de los venenos de serpiente Cascabel (Crotalus durissus durissus) de ejemplares adultos y recien nacidos
(1983)
Venoms from adult and newborn Central American rattlesnakes (Crotalus durissus durissus) were compared for lethal, proteolytic, hemorrhagic, myonecrotic, edematigenous and in vitro hemolytic activities. Electrophoretic and ...
Neutralization of proteolytic and hemorrhagic activities of Costa Rican snake venoms by a polyvalent antivenom
(1985)
The polyvalent antivenom produced at the Instituto Clodomiro Picado, Costa Rica, was tested for its capacity to neutralize proteolytic and hemorrhagic activities of ten Costa Rican crotaline venoms. In experiments with ...
Neutralization of local effects of the terciopelo (Bothrops asper) venom by blood serum of the colubrid snake Clelia clelia
(1982)
The neutralizing capacity of the blood serum of the non-venomous snake Clelia clelia against the hemorrhagic, edematous and myonecrotic effects of Bothrops asper venom in white mice was tested using in vitro preincubation ...
Activation of the lytic program of the Epstein–Barr virus in Burkitt's lymphoma cells leads to a two steps downregulation of expression of the proapoptotic protein BimEL, one of which is EBV-late-gene expression dependent
(Virology 387 (2009) (1) p.41.49, 2009-02-28)
The Epstein–Barr virus (EBV) generally latently infects its target cells with expression of genes conferring resistance to apoptosis. However, the modulation of apoptotic signals during lytic cycle remains poorly understood. ...
Tobacco smoking modifies association between Gln-Arg 192 polymorphism of human paraoxonase gene and risk of myorcardial infarction
(2000)
Paraoxonase, a high density lipoprotein—associated human serum enzyme, plays a role in atherosclerosis by protecting against lipid peroxidation. Its activity is modulated by 2 common amino acid polymorphisms at positions ...
