Blueberry (Vaccinium angustifolium) flavonoid-containing fractions have been shown to inhibit MMP activity (MMP-2/-9) in DU145 prostate cancer cells. This study examined the effect of a whole cranberry extract on MMP activity in DU145 cells. MMP-2/-9 activity was inhibited by this cranberry extract ...

Using information from published studies, the relative sensitivity of various freshwater fish to a range of chemicals was examined. Specifically, the objectives were to: (1) determine which species are used most often in toxicity tests, (2) assess the relative sensitivity of these species to various...

Juvenile rainbow trout (Oncorhynchus mykiss) were exposed to 0, 10, 30, and 70% (v/v) of a secondary-treated, integrated thermomechanical-bleached kraft pulp and paper mill effluent. The immunological parameters oxidative burst and phagocytosis of head kidney macrophages and total and differential c...

The marine red alga Renouxia antillana is reported from Hae Island off the southern coast of Phuket Island, representing a new species record for Thailand and the Indian Ocean (specifically the Andaman Sea). This record extends the distribution range of the alga significantly farther west from its o...

The marine benthic red algae of Motupore Island and vicinity in the Port Moresby area (Papua New Guinea) are documented and 36 of the 161 species are illustrated. All records are listed with bibliographic, biogeographic, taxonomic and nomenclatural comments. The discovery of the east Australian spec...

Nymphs of Pteronarcys biloba Newman and attached chironomid larvae (Nanocladius [Plecopteracoluthus] undescribed sp, nr. branchicolus) were collected from Catamaran Brook, New Brunswick, in May and November 1997 for stable-carbon- and stable-nitrogen-isotope analysis. Nanocladius (P.) sp. had mean (...

In the intermediate zone of the inflorescence of genera of Aroideae one can find flowers with male and female characteristics. Until now, two types of developmental sequences of atypical bisexual flowers (ABFs) have been recognized: the Philodendron type and the Cercestis type. In the Philodendron t...

A method to evaluate the expression of three hormone responsive genes, vitellogenin (estrogens), spiggin (androgens), and an androgen receptor (AR beta) using real-time PCR in threespine stickleback is presented. Primers were designed from previously characterised spiggin and AR beta sequences, whil...

A comparative developmental study of the inflorescence of Philodendron solimoesense was conducted using scanning electron microscopy. The spadix of P. solimoesense is characterized by unisexual flowers. Staminate flowers are initiated on the upper portion of the spadix while pistillate flowers devel...

Experiments were conducted to examine the effects of a thermomechanical (TMP)/bleached kraft pulp and paper mill effluent (BKME), dehydroabietic acid (DHAA), hypoxia, and combinations of hypoxia and effluent on juvenile rainbow trout. In the first two experiments, trout were exposed for 4 weeks to 0...

A system for the removal and control of dissolved oxygen (DO) from freshwater was designed and constructed with aquarium-type fish studies in mind. Degassed water was obtained using a partial vacuum of -14 psi, and DO regulated at an aquarium scale using electronically controlled aeration with timed...

This monographic study presents morphological descriptions of eight species of Padina collected from the Visayas and Mindanao regions of southern Philippines, including distributions of each species and a taxonomic key for all the species examined. Of these species, three are new records for the Phi...

The spadix of Arum italicum Miller consists of two main parts: a clavate sterile portion (appendix) and a cylindroid fertile portion. In the fertile portion with both male and female zones, there are two zones of sterile flowers (bristles). The basal portion of bristles is surrounded by a verrucose ...

White sucker (Catostomus commersoni) caged for 3 days in a bleached kraft mill effluent (BKME) stream had elevated mixed function oxygenase (MFO) activities 15-90 fold those of fish caged in a reference stream. Liver composites of male and female fish were ground and extracted with dichloromethane (...

Rainbow trout (Oncorhynchus mykiss) were exposed to 1.5 and 15% v/v secondary treated sewage effluent for 32 weeks in flow-through mesocosms. The exposure encompassed the full period of reproductive development for rainbow trout. Trout did not show any evidence of a dose-dependent change in growth. ...

The effects of point-source and diffuse discharges on resident populations of brown bullhead catfish (Ameiurus nebulosus (LeSueur, 1819)) in the Waikato River (New Zealand) were assessed at sites both upstream and downstream of point-source discharges. At each site, the population parameters, relati...

This study deals specifically with floral organogenesis and the development of the inflorescence of Philodendron squamiferum and P. pedatum. Pistillate flowers are initiated on the lower portion of the inflorescence and staminate flowers are initiated on the distal portion. An intermediate zone cons...
