Effect of an In Vitro Digestion on the Antioxidant Capacity of a Microfiltrated Blackberry Juice (Rubus adenotrichos)
(2018)
The health benefits attributed to berries are largely dependent on their bioavailability. This study evaluated the antioxidant activity for different samples of blackberry juice submitted to an in vitro digestion. The HPLC ...
An alternative in vitro method for testing the potency of the polyvalent antivenom produced in Costa Rica
(1988)
The ability of several batches of polyvalent antivenom to neutralize indirect hemolytic activity of Bothrops asper venom was studied using a sensitive plate test. All samples of antivenom tested effectively neutralized ...
Effect of Gamma Irradiation and Selection with Fungus Filtrate (Rhizoctonia solani Kuhn) on the in Vitro Culture of Common Bean (Phaseolus vulgaris)
(2015)
The present investigation was undertaken to study the effect of gamma irradiation (dose from 10 to 100 Gy) and in vitro selection with fungus filtrate as selecting agent (concentration from 20% to 100%) on the susceptibility ...
Comparative study on coagulant, defibrinating, fibrinolytic and fibrinogenolytic activities of Costa Rican crotaline snake venoms and their neutralization by a polyvalent antivenom
(1989)
The coagulant, defibrinating, fibrino lytic and fibrinogenolytic activities of venoms from ten species of Costa Rican crotaline snakes were studied, together with the neutralization of these effects by a polyvalent antivenom. ...
Effects of Bothrops asper snake venom on the expression of cyclooxygenases and production of prostaglandins by peritoneal leukocytes in vivo, and by isolated neutrophils and macrophages in vitro
(2009-03)
In this study, the ability of Bothrops asper snake venom (BaV) to increase the production of prostaglandins PGE2 and PGD2 was assessed in a mouse model in vivo and in inflammatory cells in vitro. In addition, the expressions ...
In vitro studies to evaluate the wound healing properties of Calendula officinalis extracts
(2017)
Ethnopharmacological relevance: Calendula officinalis (pot marigold) flower extracts have a long-lasting tradition in ethnopharmacology. Currently, the European Medicines Agency (EMA) has approved its lipophilic and aqueous ...
Ultrastructure and histology of organogenesis induced from shoot tips of maize (Zea mays, Poaceae)
(Rev. biol. trop vol.57 supl.1 San José nov. 2009, 2009-11)
Shoot tips of maize (Zea mays L.) were cultured on Murashige and Skoog medium supplemented with 2 mg/l BA +1 mg/l 2,4-D +40 mg/l, to investigate phases of ontogenetic development. The study used light microscopy as well ...
In vitro propagation of purple pitahaya (Hylocereus costaricensis [F.A.C. Weber] Britton & Rose) cv. Cebra
(2012-10)
Limitations to large-scale propagation of purple pitahaya (Hylocereus costaricensis [F.A.C. Weber] Britton & Rose), a potential source of betalains for the food industry, can be overcome through utilization of in vitro ...
In vivo and in vitro genetic evidence of involvement of neuregulin 1 in immune system dysregulation
(J Mol Med (Berl). 2010 November ; 88(11): 1133–1141, 2010-11)
Neuregulin 1 (NRG1) has been implicated in several disorders including breast cancer, multiple sclerosis, and schizophrenia. Also, recent evidence suggests that NRG1 may play a role in regulation of inflammation and immune ...
Responses of Arabica coffee (Coffea arabica L. var. Catuaí) cell suspensions to chemically induced mutagenesis and salinity stress under in vitro culture conditions
(2018)
Crop improvement of Coffea arabica L. (coffee) via mutagenesis could accelerate breeding programs; thus, the present study aimed to develop an in vitro protocol using the chemical mutagens sodium azide (NaN3) and ethyl ...
