Phototaxis, gravitaxis and vertical migrations in the marine dinoflagellate Prorocentrum micans

The phototactic orientation of the marine dinoflagellate Prorocentrum micans was studied at three different ages and at several light intensities. High irradiances caused the cells to show negative phototaxis and low irradiances caused positive phototaxis. The precision of negative phototaxis reached a maximum in the early afternoon, while the precision of positive phototaxis was found to peak in the morning and at night. The cells also showed a pronounced negative gravitactic orientation, which had a maximum in precision in the early afternoon. The degree of gravitaxis was found to be constant over time when the cells were confined to a closed cuvette for up to 9 h. As a consequence of the orientation strategies, populations of Prorocentrum micans showed daily vertical migrations in a 3-m Plexiglas column. They accumulated in the top layers in the afternoon and were almost randomly distributed during the rest of the day.
Online couples mindfulness-based intervention for young breast cancer survivors and their partners: A randomized-control trial

Abstract Purpose Young breast cancer survivors (YBCS) face unique challenges in coping with disease, distress, and relationship concerns. The purposes of this study were to understand the acceptability and feasibility of an online Mindfulness-Based Intervention (MBI) for YBCS and their partners (i.e., Couples Mindfulness-Based Intervention: C-MBI) and to compare the effectiveness of the C-MBI to a closely-matched control, an online MBI for individuals (I-MBI). Methods YBCS and their partners were recruited. Couples were randomly assigned to an 8-week C-MBI (couples = 41) or to I-MBI (couples = 36), which included one-hour video modules, a manual, and guided-meditation audios. Both couple members participated in the C-MBI; only the YBCS participated in the control I-MBI. Participants answered surveys about individual- and couple-level functioning at baseline and post-intervention. Results Online delivery was shown to be feasible and acceptable. For YBCS and their partners, levels of perceived stress, anxiety, depression, and fatigue were lower after the intervention, in both conditions. Unexpectedly, however, participating in the C-MBI appeared to have detrimental effects on dyadic adjustment and relationship quality. Conclusion Although YBCS and their partners reported online delivery was acceptable and benefited well-being, for couple-based MBIs to have benefits for relationship functioning, it may be necessary for couples to have the support of other couples and an instructor. Online delivery may be particularly acceptable and effective for clinical populations, including YBCS. Medical professionals may be more likely to recommend online-MBI programs to cancer survivors, because the programs are of little or no cost.
Food sources of common dolphinfish (Coryphaena hippurus) based on stomach content and stable isotopes analyses

Dolphinfish (Mahimahi) are a high-demand resource for sport and coastal fisheries, mainly in the Pacific Ocean. Due to their economic and ecological importance, studies of their biology are very important to understand their function in ecosystems. We used stable isotope and stomach content analyses to determine the most important prey of the common dolphinfish, as well as the trophic level of this species in two areas of the southern Gulf of California. Stomach contents of 445 specimens were analysed. Using both techniques, we found that the most important prey for dolphinfish in the southern Gulf of California were three invertebrate species followed by fish. This contrasts with results from other authors who found that this species was mainly piscivorous in other locations. Stomach content analysis indicated differences in prey biomass by area, season and size class. The isotopic analysis did not show significant differences between seasons or sexes. Both stomach contents and stable isotope analyses showed that although this predator consumed a wide prey spectrum, only a few prey items made up the bulk of the diet, which resulted in a low SD in δ15N values and low Levin's index values. We conclude that this fish is an opportunistic predator that may consume a wide prey spectrum, but that it mainly consumes prey that are abundant in the area, such as crustaceans and cephalopods in the Gulf of California.
Janus‐faced course of COVID‐19 infection in patients with hematological malignancies

The COVID-19 pandemic affects most countries of the world resulting in significant morbidity and mortality from this infection with SARS-CoV2 (1). It was reported that among others specifically patients with cancer (including patients with hematological malignancies) are at a higher risk for severe and fatal infection (2). Here, we report three consecutive patients with underlying hematologic malignancies and co-morbidities who were admitted to the infectious diseases ward at our department because of SARS-CoV2 infection.
Endothelial Dysfunction and Coronary Vasoreactivity - A Review of the History, Physiology, Diagnostic Techniques, and Clinical Relevance

The fervency for advancement and evolution in percutaneous coronary intervention has revolutionised the treatment of coronary artery disease. Historically, the focus of the interventional cardiologist was directed at the restoration of luminal patency of the major epicardial coronary arteries, yet whilst this approach is evolving with much greater utilisation of physiological assessment, it often neglects consideration of the role of the coronary microcirculation, which has been shown to clearly influence prognosis. In this review, we explore the narrative of the coronary circulation as more than just a simple conduit for blood but an organ with functional significance. We review organisation and physiology of the coronary circulation, as well as the current methods and techniques used to examine it. We discuss the studies exploring coronary artery endothelial function, appreciating that coronary artery disease occurs on a spectrum of disorder and that percutaneous coronary intervention has a latent effect on the coronary circulation with long-term consequences. It is concluded that greater recognition of the coronary artery endothelium and mechanisms of the coronary circulation should further guide revascularisation strategies.
Beyond Short-Term Snippet: Video Relation Detection With Spatio-Temporal Global Context

Video visual relation detection (VidVRD) aims to describe all interacting objects in a video. Different from relationships in static images, videos contain an addition temporal channel. A majority of existing works divide a video into short segments, predict relationships in each segment, and merge them. Such methods cannot capture relations involving long motions. Predicting the same relationship across neighboring video segments is also inefficient. To address these issues, this work proposes a novel sliding-window scheme to simultaneously predict short-term and long-term relationships. We run windows with different kernel sizes on object tracklets to generate sub-tracklet proposals with different duration, while the computational load is similar to that in segment-based methods. To fully utilize spatial and temporal information in videos, we construct one spatial and one temporal graph and employ Graph Convloutional Network to generate contextual embedding for tracklet proposal compatibility evaluation. We only predict relationships on highly-compatible proposal pairs. Our method achieves state-of-the-art performance on both ImageNet-VidVRD and VidOR dataset across multiple tasks. Especially for ImageNet-VidVRD, we obtain an average of 3\% (R@50 from 8.07\% to 11.21\%) improvement under all evaluation metrics.
Host Plants and Host Plant Preference Studies for Bactrocera invadens (Diptera: Tephritidae) in Kenya, a New Invasive Fruit Fly Species in Africa

Abstract Bactrocera invadens Drew, Tsuruta & White (Diptera: Tephritidae), an invasive fruit fly species of Asian origin, was detected in Kenya in 2003, and is now well established in several parts of the country. We assessed the host range of this major quarantine pest in Kenya by collecting a wide range of cultivated and wild host plants from December 2004 to April 2006. Fruit were collected from 90 plant species representing 40 families from the Coast, Eastern, and Rift Valley provinces of the country where the fly population had been observed to occur in large numbers and where fruit and vegetable production is predominant. Fourteen plant species, among them cultivated and wild fruiting species, were found to be hosts of B. invadens. Fruit of mango, Mangifera indica L. (Anacardiaceae); banana Musa sp. AAA (Musaceae); and citrus [Citrus limon (L.) Burm.f. (lemon), Citrus reticulata Blanco (tangerine), and Citrus sinensis (sweet orange) (all Rutaceae)], were among the cultivated species heavily infested by B. invadens. Marula Sclerocarya birrea (A.Rich) Hochst. (Anacardiaceae) and Terminalia catappa L. (Combretaceae) were found to be the most infested noncultivated plants. These wild plants evidently ensure that sufficient reproductive bases exist for B. invadens during the off-season when the cultivated hosts are not in fruiting. In laboratory host preference studies, mango and banana were found to be the most preferred host plants among the nine cultivated plant species tested.
Effects of flashing light from light emitting diodes (LEDs) on growth of the microalga Isochrysis galbana

The growth of Isochrysis galbana was examined under flashing- and non-flashing-light conditions. Cell densities were higher under flashing light at 104 μmol photons m–2 s–1than at 60 μmol m–2 s–1. At high daily irradiance, cell densities were significantly higher under flashing light at most frequencies than in control cultures under non-flashing light. Final cell density was highest at a flash frequency of 10 kHz, at approximately 1.3 times those of control cultures. For cultures at 10 kHz flash frequency, final cell densities at duty cycles from 40 to 80% were about 1.7 times those at 11%. Key words: Algal growth, duty cycle, flashing-light effect, light emitting diodes (LED), light conditions.
POPULATION DYNAMICS OF EUROPEAN GROUND SQUIRRELS (SPERMOPHILUS CITELLUS) IN A SUBURBAN AREA

Abstract We monitored European ground squirrels (Spermophilus citellus) in a recreation area near Vienna, Austria, over a 7-year period to follow their population dynamics. Data were obtained by mark–recapture and daily checklists in an attempt to track the fates of individuals present in a defined area. Abundance of nonjuveniles present in spring decreased from 56.0 individuals/ha in 1992 to 6.3 individuals/ha in 1998. Litter size and yearling-male reproduction were inversely related to density, whereas immigration, juvenile survival, and proportions of nonjuvenile males exhibited a positive relationship. We conclude that the study population had been a dispersal sink and that ceasing immigration combined with poor local survival caused the population to crash. The temporal coincidence of these 2 effects indicates an extrinsic factor acting both on residents and potential immigrants.
Economic Life of Coastal Communities: A Study of Meleura Beach Tourism Objects

This study aims to determine the impact of the Meleura Beach attraction for the economic life of the Lakarinta Coastal community, Lohia District, Muna Regency. This research was conducted using qualitative methods or purposive sampling techniques. The results showed that the local community felt a positive impact on the existence of this beach area, especially those directly involved with the development of Meleura beach tourism objects both economically. The development of Maleura Beach also has an economic impact, in the form of changes or shifts in the livelihoods of most Lakarinta villagers, from farmers to traders and service providers. Changes and/or transitions like this are followed by changes in community income which also shows an increasing trend. If before the beach was developed, the majority of residents who had jobs as farmers were only able to receive between Rp 1,000,000-5,000,000 per year, now on average they are able to receive more than Rp 10,000,000 per year, even some of them can receive more than Rp 100,000,000 per year. The need for solid government funding and community institutions to help improve the economic life of the community and help provide solutions that benefit the community.
Nutritional Deprivation Index is negatively associated with socio-economic factors in Paraguayan households

The present study aimed to examine the nutritional deprivation of Paraguayan households (measured as households' access to diverse diets) and investigate the association between nutritional deprivation and socio-economic characteristics in a large sample. An extension of Alkire–Foster methodology, a technique widely employed in multidimensional poverty measurement, was used to calculate both the incidence and intensity of nutritional deprivation. The resulting Nutritional Deprivation Index allows us to consider minimum food group requirements that vary by food groups as well as by individual characteristics such as age, sex and activity level. Applying the methodology to a nationally representative sample of households from the 2011–2012 Income and Expenditures Household Survey, the study found that about two in every three Paraguayan households (67 %) were inadequately nourished in at least four (of the total of six) food groups. Although no significant differences were found between rural and urban households, the incidence of multi-dimensionally deprived households generally decreased as income increased. Logistic regression results showed that nutritional deprivation decreased as household income and mother's education increased and increased with household size. Our study concludes that the majority of Paraguayan households is significantly nutritionally deprived across most food groups and suggests that strategies are needed to improve their access to diverse diets, especially among its lower- and middle-income segments.
Rhodopsin 7 and Cryptochrome - circadian photoreception in Drosophila

The blue light photopigment cryptochrome (CRY) is thought to be the main circadian photoreceptor of Drosophila melanogaster. Nevertheless, entrainment to light-dark cycles is possible without functional CRY. Here, we monitored phase response curves of cry mutants and control flies to 1-hour 1000-lux light pulses. We found that cry mutants phase-shift their activity rhythm in the subjective early morning and late evening, although with reduced magnitude. This phase-shifting capability is sufficient for the slowed entrainment of the mutants, indicating that the eyes contribute to the clock’s light sensitivity around dawn and dusk. With longer light pulses (3 hours and 6 hours), wild-type flies show greatly enhanced magnitude of phase shift, but CRY-less flies seem impaired in the ability to integrate duration of the light pulse in a wild-type manner: Only 6-hour light pulses at circadian time 21 significantly increased the magnitude of phase advances in cry mutants. At circadian time 15, the mutants exhibited phase advances instead of the expected delays. These complex results are discussed.
The Importance Of Subtypes Of Conduct Disorders In Clinical Practice

Introduction: Contemporary diagnostic classification of mental disorders classifies antisocial behavior in children and adolescents under the age of 18 as conduct disorder. Based on the age of onset, there are two subtypes of conduct disorder: Childhood and adolescent onset. Aim: Aim of the stady reports was to show different aetiologies and developmental courses of conduct disorder in two male patients, age 10 and 16 years, as well as differences in applied treatments and prognosis in the afore-mentioned cases. Individual, family and psychosocial factors related to the disorder in these patients were discussed and brought the obtained results into the context of exsisting literature. Conclusion: Despite the similar clinical symptoms that led to the diagnosis of conduct disorders, the patients differed in developmental courses of disorder, individual characteristics, individual and family history, family and social conditions, as well as treatment and prognosis. It was emphasized that the existence of subtypes of the conduct disorder according to the onset of disorder, contributes to an easier orientation in clinical work and the choice of more efficient treatments directed to the specific needs of young people with conduct disorders.
SEO Cycles

Public equity offerings by seasoned firms (SEOs) exhibit similar but less volatile cycles than initial public offerings (IPOs) of newly public firms. Our paper provides a comprehensive examination of the factors that cause variation in the number of firms issuing SEOs. Specifically, we use four factors from studies of IPOs as potential determinants of SEO cycles. We find that whether tested separately or collectively, only the demand for capital and market timing hypotheses receive strong empirical support in explaining SEO volume. Investor sentiment is not an important factor in explaining SEO volume, nor is information asymmetry.
Use of Essential Oils of Cinnamon, Lavender and Peppermint for Weed Control

The indiscriminate use of synthetic chemical compounds for weed control has been often responsible of damage to both the environment and the human health. To challenge these problems, in the last years research has increased its effort to find out alternative farming strategies. A feasible alternative could be the identification of natural substances with allelopathic effects for the realization of natural herbicides. Some research has already highlighted the possibility of using essential oils, extracted from aromatic plants, for weed control. The advantage in the utilization of such natural compounds is the quickly breaking down process into the environment and so the possible application in sustainable agriculture like organic farming. Objective of this research was the evaluation of the inhibition effect exerted by the essential oils of cinnamon, peppermint and lavender on seeds germination of some of the most common weeds species of the Mediterranean environment (pigweed, wild mustard and ryegrass). The results have highlighted a control in the weeds germination. Among the essential oils tested, cinnamon oil has exerted the highest inhibition effect compared with lavender and peppermint ones. The dicotyledonous species have been more susceptible compared with the monocotyledonous, even if it has been recorded only for redroot pigweed a dose able to inhibit totally the seed germination.
Early Weaning of Neolithic Domestic Cattle (Bercy, France) Revealed by Intra-tooth Variation in Nitrogen Isotope Ratios

Evaluating the role of milk production in prehistoric subsistence economies requires a better estimation of the capacity of a milk-oriented husbandry under prehistoric conditions. Weaning pattern, which is linked to the length of lactation, is an important parameter in this estimation. In this study, weaning pattern is closely examined in Neolithic cattle from the site of Bercy (Paris, France, c. 4000 bc ), by a study of intra-tooth (M1, M2) variation in the nitrogen isotope ratios (δ15N) of dentine collagen. Collagen δ15N is commonly used to trace the change of trophic level at weaning time. The pattern of change in collagen δ15N in the first molar of two archaeological bovines is then compared with that observed in modern cattle weaned at known age. Results suggest that the Neolithic calves were weaned early. This could reflect either a shorter lactation for Neolithic cows, or early weaning imposed by the herder in order to reserve a bigger proportion of milk production for human consumption.
Nocturnally retained zeaxanthin does not remain engaged in a state primed for energy dissipation during the summer in two Yucca species growing in the Mojave Desert

Differently oriented leaves of Yucca schidigera and Yucca brevifolia were characterized in the Mojave Desert with respect to photosystem II and xanthophyll cycle activity during three different seasons, including the hot and dry summer, the relatively cold winter, and the mild spring season. Photosynthetic utilization of a high percentage of the light absorbed in PSII was observed in all leaves only during the spring, whereas very high levels of photoprotective, thermal energy dissipation were employed both in the summer and the winter season in all exposed leaves of both species. Both during the summer and the winter season, when energy dissipation levels were high diurnally, xanthophyll cycle pools (relative to either Chl or other carotenoids) were higher relative to the spring, and a nocturnal retention of high levels of zeaxanthin and antheraxanthin (Z + A) occurred in all exposed leaves of both species. Although this nocturnal retention of Z + A was associated with nocturnal maintenance of a low PSII efficiency ( F v / F m ) on a cold winter night, pre-dawn F v / F m was high in (Z + A)retaining leaves following a warm summer night. This indicates nocturnal engagement of Z + A in a state primed for energy dissipation throughout the cold winter night ‐ while high levels of retained Z + A were not engaged for energy dissipation prior to sunrise on a warm summer morning. Possible mechanisms for a lack of sustained engagement of retained Z + A for energy dissipation at elevated temperatures are discussed.
Diversidade do gene de canal de sódio regulado por voltagem de Aedes aegypti Linnaeus, 1762 (Diptera: Culicidae) e resistência a piretróide

In Brazil, control of adults of the dengue vector, the mosquito Aedes aegypti, is performed with pyrethroid insecticides. However, despite the recent implementation of this compound in national scale, several populations of this vector are already resistant. The voltage gated sodium channel is the pyrethroid target site, in the insect nervous system. We investigated the molecular diversity of a particular region of this gene (AaNaV) in Ae. aegypti Brazilian populations in order to identify potential substitutions implicated with insecticide resistance. Cloning and sequencing of the genome region between the AaNaV exons 20 and 21 in individuals from five distinct localities, confirmed polymorphism in the intron and in two positions of exon 20, these latter related to synonymous substitutions. According to these characteristics sequences were grouped into types A or B. Two additional predictive substitutions were noted: Ile Met and Val  Ile, respectively, in 1011 and 1016 sites, both only in type A sequences. Individuals from the Rockefeller insecticide susceptible reference strain exhibited only type B sequences and the wild alleles on both 1011 and 1016 positions. Allelespecific PCR molecular typing of individuals from 15 localities showed that the Ile1011Met mutation is widespread throughout Brazil, whereas Val1016Ile is more proeminent toward the middle of the country. In five localities typing was performed separately in susceptible or resistant individuals; the mutant 1016Ile allele was significantly more present in the resistant ones, especially in homozygozity, suggesting the recessive character of this resistant mutation. Surprisingly, a series of observations suggested the occurrence of a gene duplication consisting of both type B and A sequences this last one with the 1011Met mutation. Typing of the 1011 site in the offspring of couples with specific genotypes corroborated this hypothesis. Finally, comparisons among lineages selected or not with pyrethroid suggested negative pleiotropic effects of resistance on development and reproduction aspects.
