(Wiley, 2020-06)The objectives of the present study were (experiment 1) to characterized development and dynamics of the dominant follicles (DF) and the corpus luteum (CL) to determine patterns of two (W2) and three (W3) follicular waves ... -
Following the star: Inflorescence heliotropism
(Elsevier, 2018-03)Plant movements in response to directional solar radiation, known as “heliotropism” are frequently observed in nature. Although there is a considerable amount of literature on these movements in vegetative organs, knowledge ... -
Los fondos rotatorios como estrategia organizativa
(Facultad de Administración, Economía y Negocios, Universidad Nacional de Formosa, 2020-11)El acceso de los pequeños productores al crédito fue –y continúa siendo–, muy bajo, por lo que las organizaciones que los agrupan en el departamento Libertador General San Martín (Chaco), comenzaron hace más de una década ... -
Food and Host Searching Decisions Made by Ibalia leucospoides (Hymenoptera: Ibaliidae), a Parasitoid of Sirex noctilio (Hymenoptera:Siricidae)
(2012-07)During their adult life, parasitoids—insects that lay eggs in or on other arthropods eventually killing them- spend a significant proportion of their lifetime searching for hosts, this behavior will determine their future ... -
Food habits of Oligoryzomys longicaudatus (Rodentia) in a steppe–forest transitional area of Argentinean Patagonia
(Asociación Argentina de Ecología, 2014)We described the spatial and seasonal variation of feeding habits of Oligoryzomys longicaudatus in four environments of the steppe-forest transition zone of Argentinean Patagonia. Composition of fecal pellets collected ... -
Food partitioning between the Mara (Dolichotis patagonum) and the introduced hare (Lepus europaeus) in the Monte desert, Argentina
(Taylor & Francis, 1997)In the semiarid Monte desert, Río Negro province, the mara (Dolichotis patagonum) and the European hare (Lepus europaeus), which was introduced about hundred years ago, today occur sympatrically, as in many regions of ... -
Foot-and-mouth disease vaccination induces cross-reactive IFN-γ responses in cattle that are dependent on the integrity of the 140S particles
(2015-02)Interferon-γ (IFN-γ) recall responses against foot-and-mouth disease virus (FMDV) in FMD vaccinated cattle are utilized to study T-lymphocyte immunity against this virus. Here, a recall IFN-γ assay based on a commercial ... -
Foot-and-mouth disease virus infection of dendritic cells triggers phosphorylation of ERK1/2 inducing class I presentation and apoptosis
(Elsevier, 2015-09)Foot-and-mouth disease (FMD) is a highly contagious viral disease of cloven-hoofed animals. This pathology is caused by foot-and-mouth disease virus (FMDV). Over time, the development of vaccines to prevent the spread of ... -
