The fungus-growing ants （Tribe Attini） are a New World group of〉 200 species, all obligate symbionts with a fungus they use for food. Four attine taxa are known to be social parasites of other attines. Acromyrmex （ Pseudoatta） argentina argentina and Acromyrmex （Pseudoatta） argentina platensis （parasites of Acromyrmex lundi）, and Acromyrmex sp. （a parasite of Acromyrmex rugosus） produce no worker caste. In contrast, the recently discovered Acromyrmex insinuator （a parasite of Acromyrmex echinatior） does produce workers. Here, we describe a new species, Acromyrmex ameliae, a social parasite of Acromyrmex subterraneus subterraneus and Acromyrmex subterraneus brunneus in Minas Gerais, Brasil. Like A. insinuator, it produces workers and appears to be closely related to its hosts. Similar social parasites may be fairly common in the fungus-growing ants, but overlooked due to the close resemblance between parasite and host workers.

The predictability of certain environmental factors that affect the life cycle of the seabob shrimp Xiphopenaeus kroyeri(Heller,1862) was evaluated in a study of its reproductive biology in an area adjacent to Babitonga Bay,State of Santa Catarina,Brazil. Monthly sampling was conducted from July 2010 through June 2011 at depths of 5,8,11,14,and 17 m.76 004 individuals were obtained,with a pronounced peak in absolute abundance in austral autumn(34 208),coinciding with the annual closed season from March to May. Grain size composition of the sediment showed the closest relationship to the distribution of individuals(multiple linear regression,P <0.05),related to their burying habit. The observed correlations between the abundance of reproductive males(bearing spermatophores) and females with spent gonads(cross-correlation,P <0.05),and between reproductive males and reproductive females(with a 1-month lag) suggest that the peak of reproductive males preceded the peak offemale ones. This result agrees with the pattern expected for females,which copulate in post-ecdysis(spent gonads). Spawning seemed to take place at greater depths,as evidenced by the concentration of reproductive females in these areas. The reproductive activities observed here confirm that this species follows a tropical/subtropical reproductive pattern,spawning continuously throughout the year,with the highest peaks in spring and autumn. The data indicate that the juvenile recruitment period observed in August-September resulted from the reproductive output noted in April–May. Additionally,the reproductive period recorded in November led to the juvenile peak observed in March–May.

Early detection of infected asymptomatic plants could prevent the dissemination of tomatobacterial canker throughout the crop and, thus, reduce associated economic losses. Reflectance spectroscopy has been proposed for the detection of diseases in plants, mainlycaused by foliar fungal pathogens. In contrast, bacterial canker is a vascular disease thatdoes not produce visible foliar symptoms until it is too late to avoid contagion to otherplants. The effects of the disease on the conductivity of the xylem have an impact onthe water content of the leaves;initially, a subtle effect that cannot be assessed with thenaked eye but can be evaluated by reflectance spectroscopy. The objective of this workwas to identify indices, based on the reflectance spectral signature of the plants, for thedetection of tomato plants affected by bacterial canker prior to the appearance of symptoms. To verify that the proposed methodology is applicable to a broad range of tomatogenotypes, two experiments were carried out with different tomato cultivars grown in potsand another on the ground in a greenhouse. Plants were inoculated with the pathogenicbacteria and the reflectance spectrum of the apical leaflet of two leaves per plant wereobtained before symptoms expression;several spectral indices were calculated from thereflectance spectra. Three indices, of the shortwave-infrared zone, allowed the detectionof bacterial canker inoculated plants in a fast and non-destructive way, up to one weekbefore symptoms were visible: Normalized Difference Water Index (NDWI), Simple Ratioof Water Index (SRWI) and Water Index 1 180 (WI1180). Our research demonstrates, forthe first time, the usefulness of spectral indices sensitive to water content for the identifi-cation of diseased plants. These indices arise as a promising tool for the early detection ofvascular plant diseases, that could be integrated into sustainable management plans.

The estimates of global incidence and prevalence of non-alcoholic fatty liver disease(NAFLD) are worrisome, due to the parallel burden of obesity and its metabolic complications. Indeed, excess adiposity and insulin resistance represent two of the major risk factors for NAFLD; interestingly, in the last years a growing body of evidence tended to support a novel mechanistic perspective, in which the liver is at the center of a complex interplay involving organs and systems, other than adipose tissue and glucose homeostasis. Bone and the skeletal muscle are fat- free tissues which appeared to be independently associated with NAFLD in several cross-sectional studies. The deterioration of bone mineral density and lean body mass, leading to osteoporosis and sarcopenia, respectively, are age-related processes. The prevalence of NAFLD also increases with age. Beyond physiological aging, the three conditions share some common underlying mechanisms, and their elucidations could be of paramount importance to design more effective treatment strategies for the management of NAFLD. In this review, we provide an overview on epidemiological data as well as on potential contributors to the connections of NAFLD with bone and skeletal muscle.

Neurotrophins are a family of proteins that support neuronal proliferation, survival, and differentiation in the central and peripheral nervous systems, and are regulators of neuronal plasticity. Nerve growth factor is one of the best-described neurotrophins and has advanced to clinical trials for treatment of ocular and brain diseases due to its trophic and regenerative properties. Prior trials over the past few decades have produced conflicting results, which have principally been ascribed to adverse effects of systemic nerve growth factor administration, together with poor penetrance of the blood-brain barrier that impairs drug delivery. Contrastingly, recent studies have revealed that topical ocular and intranasal nerve growth factor administration are safe and effective, suggesting that topical nerve growth factor delivery is a potential alternative to both systemic and invasive intracerebral delivery. The therapeutic effects of local nerve growth factor delivery have been extensively investigated for different ophthalmic diseases, including neurotrophic keratitis, glaucoma, retinitis pigmentosa, and dry eye disease. Further, promising pharmacologic effects were reported in an optic glioma model, which indicated that topically administered nerve growth factor diffused far beyond where it was topically applied. These findings support the therapeutic potential of delivering topical nerve growth factor preparations intranasally for acquired and degenerative brain disorders. Preliminary clinical findings in both traumatic and non-traumatic acquired brain injuries are encouraging, especially in pediatric patients, and clinical trials are ongoing. The present review will focus on the therapeutic effects of both ocular and intranasal nerve growth factor delivery for diseases of the brain and eye.

Safe application of chromium （Cr）-containing organic industrial wastes to soil requires considering the ability of the soil to adsorb Cr. In this study, the maximum Cr adsorption capacity was assessed for the bulk samples and their clay and iron-free clay fractions of four subtropical soils differing in mineralogy. To this end, the samples were supplied with Cr（Ⅲ） nitrate solutions at pH 4.5 or 5.5. The results of Cr（Ⅲ） adsorption fitted to a Freundlich equation and the adsorption capacity was positively correlated with soil organic matter and iron oxide contents. The clay fractions adsorbed more Cr per unit mass than the bulk soils and the iron-free clay fractions. The Cr（Ⅲ） adsorption capacity increased with increasing soil pH due to more charges on adsorbing surfaces. Our results suggest that the soils rich in organic matter and iron oxides and having a pH above 4.5 are suitable for application of Cr（Ⅲ）-loaded industrial wastes.
