Abstract
NF-YAs encode subunits of the nuclear factor-Y (NF-Y) gene family. NF-YAs represent a kind of conservative transcription factor in plants and are involved in plant growth and development, as well as resistance to biotic and abiotic stress. In this study, 16 maize (Zea mays) NF-YA subunit genes were identified using bioinformatics methods, and they were divided into three categories by a phylogenetic analysis. A conserved domain analysis showed that most contained a CCAAT-binding transcription factor (CBFB) _NF-YA domain. Maize NF-YA subunit genes showed very obvious tissue expression characteristics. The expression level of the NF-YA subunit genes significantly changed under different abiotic stresses, including Fusarium graminearum infection and salicylic acid (SA) or jasmonic acid (JA) treatments. After inoculation with Setosphaeria turcica and Cochliobolus heterostrophus, the lesion areas of nfya01 and nfya06 were significantly larger than that of B73, indicating that ZmNFYA01 and ZmNFYA06 positively regulated maize disease resistance. ZmNFYA01 and ZmNFYA06 may regulated maize disease resistance by affecting the transcription levels of ZmPRs. Thus, NF-YA subunit genes played important roles in promoting maize growth and development and resistance to stress. The results laid a foundation for clarifying the functions and regulatory mechanisms of NF-YA subunit genes in maize.

Abstract
The highly conserved heat shock protein 70 (HSP70) contributes to survival at a cellular level and greatly enhances stress tolerance in many organisms. In this study, we isolate and characterize Cshsp702, which encodes an inducible form of HSP70 in the rice stem borer, Chilo suppressalis. Cshsp702 does not contain introns; the translational product is comprised of 629 amino acids with an isoelectric point of 5.69. Real-time quantitative PCR revealed that Cshsp702 was expressed at maximal levels in hemocytes and was minimally expressed in the midgut. Expression of Cshsp702 in response to a range of temperatures (-11 to 43 °C) indicated significant induction by extreme cold and hot temperatures, with maximum expression after 2 h at 42 °C. The induction of Cshsp702 in response to the endoparasite Cotesia chilonis was also studied; interestingly, Cshsp702 expression in C. suppressalis was significantly induced at 24 h and 5 days, which correspond to predicted times of C. chilonis feeding and growth, respectively. The potential induction of Cshsp702 as an inflammatory response due to parasitic stress is discussed. In conclusion, Cshsp702 is induced in response to both environmental and biotic stress and plays an important role in the physiological adaptation of C. suppressalis.

Abstract
BACKGROUND Studies have shown that omega-3 (n-3) Polyunsaturated Fatty Acids (PUFAs), including docosahexaenoic acid (DHA), might have beneficial effects on somatic and mental health, potentially partly due to their mitigating effects on three major biological stress systems: the immune-inflammatory system, the hypothalamic-pituitary-adrenal-axis (HPA-axis) and the autonomic nervous system (ANS). OBJECTIVE To examine the association between (cumulative measures of) markers of three biological stress systems and n-3 PUFA and DHA plasma levels. DESIGN Plasma n-3 PUFA and DHA were measured using Nuclear Magnetic Resonance in 2724 participants from the Netherlands Study of Depression and Anxiety. Linear regression analyses (adjusted for sociodemographic, sampling, lifestyle and somatic disease variables) associated inflammation (C-reactive protein, interleukin-6, tumor necrosis factor alpha), HPA-axis (cortisol awakening response and evening cortisol) and ANS (heart rate, respiratory sinus arrhythmia and pre-ejection period) markers and cumulative indices within and across stress systems as independent variables with n-3 PUFA and DHA levels as dependent variables. RESULTS Participants had a mean age of 41.8 (SD = 13.1) and 65.7% were female. Higher levels of all three inflammation markers (Beta=-.146 to -.073, all p-values<.001), evening cortisol (Beta=-.045, p = .033) and heart rate (Beta=-.080, p < 0.001) were significantly negatively associated with n-3 PUFA. Suggesting an exposure-response relationship, a higher number of markers indicative of inflammation and hyperactive HPA-axis (p < .001 and p = .003, respectively), but not of ANS dysregulation, was found in persons with lower n-3 PUFA levels. An exposure-response relationship was also found for having a higher number of different stress system dysregulations with lower n-3 PUFA levels (p < .001). For DHA, results were in line with those for n-3 PUFA, although with slightly smaller effect sizes. CONCLUSIONS Our study confirmed that having various (cumulative) indicators of dysregulation of three biological stress systems was significantly associated with lower n-3 PUFA and DHA plasma levels. If low n-3 PUFA levels are the cause of dysregulated stress systems, then n-3 PUFA supplementation might reduce biological stress and thereby improve somatic and mental health.

Abstract
Urbanization in pre-modern populations may have had a variety of consequences related to population crowding. However, research on the effects of urbanization have provided inconsistent results regarding the biological impact of this transition on human populations. The purpose of this study is to test the hypothesis that urbanization caused an increase in overall biological stress in a medieval (10th-13th centuries AD) Polish population. A human skeletal sample (n=164) was examined for the presence of porotic hyperostosis, cribra orbitalia, linear enamel hypoplasia, periosteal reaction, and specific infectious diseases. Prevalence rates were compared among three temporal samples: initial urbanization, early urbanization, and later urbanization. Results indicate no significant trends for any of the pathological conditions. Cox proportional hazards analyses, however, revealed a significant increase in the risk of death over time, which supports the hypothesis. These results reflect the necessity of using multiple analyses to address bioarchaeological questions. The lack of significant results from skeletal indicators may be due to an earlier urbanization trend in the population. This study illustrates that the association of urbanization with elevated biological stress is complicated and dependent on various factors, including culture and time period.

Abstract
To get closer to the environmental reality, ecotoxicological studies should no longer consider the evaluation of a single pollutant, but rather combination of stress and their interaction. The aim of this study was to determine if responses of a fish to a sudden biological stress could be modified by a prior exposure to a chemical stress (a polymetallic contamination). For this purpose, in situ experiment was conducted in three ponds in the Haute-Vienne department (France). One pond was chosen for its high uranium concentration due to uranium mine tailings, and the two other ponds, which were not submitted to these tailings. Three-spined sticklebacks (Gasterosteus aculeatus) were caged in these ponds for 14 days. After this period, fish were submitted to a biological stress, exerted by lipopolysaccharides injection after anesthesia, and were sacrificed 4 days after these injections for multi-biomarkers analyses (leucocyte viability, phagocytic capacity and reactive oxygen species production, antioxidant peptide and enzymes, lipid peroxidation and DNA damage). The pond which received uranium mine tailings had higher metallic concentrations. Without biological stress, sticklebacks caged in this pond presented an oxidative stress, with increasing of reactive oxygen species levels, modification of some parts of the antioxidant system, and lipid peroxidation. Caging in the two most metal-contaminated ponds resulted in an increase of susceptibility of sticklebacks to the biological stress, preventing their phagocytic responses to lipopolysaccharides and modifying their glutathione contents and glutathione-S-transferase activity.

Abstract
Saffron (Crocus sativus) is a medicinally important plant. The Kashmir valley (J&K, India) emblematizes one of the major and quality saffron producing areas in the world. Nonetheless, the area has been experiencing a declining trend in the production of saffron during the last decade. Poor disease management is one of the major reasons for declining saffron production in the area. Endophytes are known to offer control against many diseases of host plant. During the present study, culturable bacterial endophytes were isolated from saffron plant, identified and assessed for plant growth promoting activities. Molecular and phylogenetic analysis grouped the fifty-four bacterial isolates into eleven different taxa, viz. Bacillus licheniformis, B. subtilis, B. cereus, B. humi, B. pumilus, Paenibacillus elgii, B. safensis, Brevibacillus sp., Pseudomonas putida, Staphylococcus hominis and Enterobacter cloacae. The results were also supported with the identification based on BIOLOG system. B. licheniformis was the dominant endophyte in both leaves and corms of saffron. 81 % isolates showed lipase activity, 57 % cellulase, 48 % protease, 38 % amylase, 33 % chitinase and 29 % showed pectinase activity. 24 % of the isolates were phosphate solublizers, 86 % showed siderophore production and 80 % phytohormone production potential. The present repository of well characterized bacterial endophytes of saffron, have plant growth promoting potential which can be explored further for their respective roles in the biology of the saffron plant.
