Reproductive biology of the nonnative oyster, Crassostrea gigas (Thunber, 1793) as a key for its successful spread along the rocky shores of Northern Patagonia, Argentina
Crassostrea gigas was introduced in Anegada Bay (North Patagonia, Argentina), in 1981 for aquaculture purposes. The species has, since established in the field, covered all available hard substrata in the bay and gradually expanded south along the coast of the neighboring province of Río Negro, 90 km away from its original introduction site. Our work focused on the reproductive dynamics of the species at the introduction site, with emphasis on the thermal thresholds needed for each stage of gonad development. During early spring, the oysters in Anegada Bay go through active gonad proliferation. Maturity extends mainly from October to January. The first spawning occurs in November, when seawater temperature exceeds 17°C, and peaks from December to February, when seawater temperature lies in the range ot 19–21.5°C. The timing of gonad development is size dependent. Larger (≥70 mm) and medium-size oysters begin spawning first, whereas small oysters ( 17°C), and spawning only occurs in those sites where this threshold is reached.Versión del editor

Gastroprotective potential of Buddleja scordioides Kunth: Effects into the modulation of antioxidant enzymes and inflammation markers in an in vivo model
Ethnopharmacological relevance: A common plant used to treat several gastric disorders is Buddleja scordioides Kunth,commonly known as salvilla.
Aim of thes tudy: To detect inflammatory markers,in order to evaluate the gastroprotective potential of
salvilla infusions,as this could have beneficial impact on the population exposed to gastric ulcers and
colitis.
Materials and methods: The present work attempted infusions were prepared with B. scordioides (1% w/w) lyophilized and stored.Total phenolic content and GC–MS analysis were performed. Wistar rats were
divided into five groups a negative vehicle control,an indomethacin group,and three
experimental groups,named preventive,curative,and suppressive. All rats were sacrificed under deep
ether anesthesia(6h)after the last oral administration of indomethacin/infusion.The rat stomachs were
promptly excised,weighed,and chilled in ice-cold and 0.9%NaCl.Histological analysis,nitrites
quantification and immunodetection assays were done.
Results: B.scordioides infusions markedly reduced the visible hemorrhagic lesions induced byindomethacin in rat stomachs,also showed down-regulation of COX2, IL-8 and TNFα and up-regulation of
COX-1with a moderate down-regulation of NFkB and lower amount of nitrites.However,this behavior
was dependent on the treatment,showing most down-regulation of COX-2,TNFα and IL-8 in the curative
treatment;more down-regulation of NF-kB in the preventive treatment;and more up-regulation of COX-1 for the suppressor and preventive treatments.
Conclusion: The anti-inflammatory potential of B. scordioides infusions could be related with the
presence of polyphenols as quercetin in the infusion and how this one is consumed.3.055 JCR (2015) Q1, 2/24 Integrative & complementary medicine, 36/209 Plant sciences; Q2, 16/59 Chemistry, medicinal, 72/253 Pharmacology & pharmacyUE
