The streptococcal agent OK-432 has been used for immunotherapy of head and neck cancer, among other malignancies, but its mechanism action is unknown. Because the Toll-like receptor 4 (TLR4)/MD-2 complex important in enabling mammalian immune system to recognize bacterial components, we investigated whether expression TLR4 MD-2 genes associated with OK-432-induced anticancer immunity.Peripheral blood mononuclear cells (PBMCs) from 28 patients cancer were analyzed mRNA by reverse...
Climate-change associated changes in oceanographic conditions, particularly sea surface temperatures (SSTs), have systematically affected many marine fisheries resources around Japan. The Pacific Decadal Oscillation (PDO) index is considered one of the most important climate indices for describing basin-scale SST variations North Pacific, which are closely related to decadal resources. Time series PDO has been used conventionally classify conditions ocean and Japan as either warming or...

Abstract The density dependence of growth and body condition have important impacts on fish population dynamics fisheries management. Although affects habitat selection, which in turn changes temperature, how this remains unclear. Here, we investigated annual condition, cohort-specific chub mackerel (Scomber japonicus) the western North Pacific examined quarterly condition. We hypothesized that is affected both directly (e.g. through competition for food) indirectly (through temperature) by...
We aimed to understand the effect of biological interactions on distribution small pelagic fishes. Surveys were conducted during 2003-2019 using sea surface trawl nets in western and central North Pacific Ocean, covering an area between 143° E 165° W, estimate distributions 4 fishes: saury Cololabis saira , Japanese sardine Sardinops melanostictus chub mackerel Scomber japonicus anchovy Engraulis . These species are potential competitors, as they all occupy a similar niche. was abundant...
Standardization of catch per unit effort is an effective way to not only extract temporal abundance trends but also understand distribution shifts fish resources. Chub mackerel in the Northwest Pacific has recently been great concern fishermen and fisheries managers because total increasing, fishing grounds have expanded from Japanese exclusive economic zone eastward high-sea areas. Understanding spatiotemporal dynamics chub urgently needed for evaluating current status (i.e., distribution)...
Abstract Spatiotemporal patterns in spawning of fish influence growth and survival by affecting the environment experienced offspring during their early life stages. Therefore, identifying changes can help researchers understand population dynamics recruitment fluctuations. The Japanese sardine Sardinops melanostictus is a small pelagic that undergoes large stock Although are known to change spatially temporally with abundance, little information available on processes underlying increases....
Abstract Proportionality between spawning stock biomass (SSB) and annual total egg production (TEP) has been an inherent assumption in spawner–recruitment models for fisheries management studies on recruitment mechanisms fish. However, recent evidence of density dependence led to a need reconsider the validity per (RPS), which is SSB‐based survival index from hatching recruitment, studies. Here we revisit sardine hypotheses based (RPE), TEP‐based index, by reanalyzing published data Pacific...
Parental defence behaviour can reduce the probability of nest predation, but also incurs costs (e.g. less time for foraging). Under variable risk, parental strategies that adjust amount effort to prevailing risk will be adaptive. Although predation is typically viewed as an all‐or‐none event, many nests are depredated only partially. Therefore, partial brood loss indicate occurrence and, a consequence, high risk. However, whether parents use offspring cue and increase their after has not...
Abstract Animals frequently face situations where they must choose one prey item from a set of options. are often considered to be able the best multiple alternatives. However, time may required make accurate decisions, and under natural conditions, is usually limited. Here, we examined whether animals fail most profitable time‐limited conditions. A queen (foundress) paper wasp Polistes chinensis antennalis starts colony in spring maintains nest alone until emergence workers. At stage,...
Abstract Various organisms are known to build nests with defensive structures protect their offspring from predation, but our understanding of plasticity in the nest structure remains poor. In this study, we investigated whether a paper wasp, Polistes chinensis antennalis , adjusted construction according value offspring, and also analysed effect adjusting on predator's decision attack. P. foundresses start colony maintain her alone until emergence workers. During stage, often construct...
ABSTRACT Group living is a widespread phenomenon among animals and an important trait in fishes. Understanding group composition its dynamics fundamental for elucidating ecological evolutionary processes natural populations of gregarious animal species, including fishes, but our knowledge marine fishes limited. Here, we examined ontogenetic change two Japanese sardine ( Sardinops melanostictus ) chub mackerel Scomber japonicus ). We found that, at the juvenile stage, groups were composed...

Abstract Many small pelagic fishes obligately form schools; some of these schools attain a remarkable size. Although the school is fundamental and important ecological unit site biological interactions such as competition predation, information on schooling processes in field remains scarce. Here, we examined quantitative relationships between population density size, number schools, other characteristics (i.e., packing density, volume, cross-sectional area) three species fishes: Japanese...
Abstract Density dependence is a fundamental concept for fish population dynamics. Although density-dependent growth and maturity among older juveniles adults important regulating size fisheries management, the mechanism of density marine fishes remains unclear. Here, we examined changes in Japanese sardine with increasing abundance beginning 2010s how current pattern differs from that previous stock-increase period 1970s to early 1980s. During abundance, mean standard length has already...
