There is a recent surge in demand for nutritious food from the consumer end. Functional foods are gaining much popularity. With the commercialization of omega-3 fatty acids and their many nutritional advantages, edible powders and smoothies loaded with PUFA are available on the market. Edible oil powders are one such com-modity that is consumed for their several nutraceutical properties such as, reducing cardiovascular risk, aiding in weight reduction, providing antioxidant properties, etc. Edible oil is first stabilized into stable emulsions which are then processed to obtain powders. The process of oil-in-water emulsion stabilization is carried out using ultrasonication, homogenization, microfluidization, complex coacervation, and oil structuring mechanisms. The stable emulsions are then microencapsulated using various wall material combinations and ratios to form stable edible oil powders. The wall material protects the active molecules from the ambient environment, high tem-perature, and high-pressure processing methods. These powders are added to coffee, smoothies, cookies, yogurt, cake mix, and soup powder to impart functional properties to foods. The major challenge in the production of oil powder is the formation of stable emulsion with proper wall-to-core ratio and binding of the wall with core materials to form stable powder with an increased shelf life. This article provides a detailed review of various emulsion stabilization techniques and processing methods to form edible oil powders.

Development of simple methods for preparation of polymeric electrode materials with nanofibrous network structure is a perspective way toward cheap supercapacitors with high specific capacitance and energy density. In this work one-pot synthesis of electroactive ternary composite based on polypyrrole, polyacrylamide and chitin nanofibers with beneficial morphology was elaborated. Ternary system demonstrates better electrochemical performance in comparison with both polypyrrole–polyacrylamide and polypyrrole–chitin binary composites. Possible mechanism of synergistic effect of simultaneous influence of polyacrylamide and chitin nanofibers on the formation of composite＇s structure is *** highest attained specific capacitance of electroactive polypyrrole in ternary composite reached 249 F/g at 0.5 A/g and 150 F/g at 32 A/g. Symmetrical supercapacitor was assembled using the elaborated electrode material. High specific capacitance 89 F/g and good cycling stability with capacitance retention of 90% after 3000 cycles at 2 A/g were measured.

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.

In about half the cases of involuntary childlessness, a male infertility factor is involved. The PIWI-LIKE genes, a subclade of the Argonaute protein family, are involved in RNA silencing and transposon control in the germline. Knockout of murine Piwi-like 1 and 2 homologs results in complete infertility in males. The aim of this study was to analyze whether the mRNA expression of human PIWI-LIKE I-4 genes is altered in ejaculated spermatozoa of men with impaired sperm characteristics. Ninety male participants were included in the study, among which 47 were with normozoospermia, 36 with impaired semen characteristics according to the World Health Organization （WHO） manual, 5th edition, and 7 with azoospermia serving as negative control for the PIWI-LIKE 1-4 mRNA expression in somatic cells in the ejaculate. PIWI-LIKE 1-4 mRNA expression in the ejaculated spermatozoa of the participants was measured by quantitative real-time PCR. In nonazoospermic men, PIWIoLIKE 1-4 mRNA was measurable in ejaculated spermatozoa in different proportions. PIWI-LIKE 1 （100.0%） and PIWI-LIKE 2 （49.4%） were more frequently expressed than PIWI-LIKE3 （9.6%） and PIWI-LIKE 4 （15.7%）. Furthermore, a decreased PIWI-LIKE2 mRNA expression showed a significant correlation with a decreased sperm count （P = 0.022） and an increased PIWI-LIKE 1 mRNA expression with a decreased progressive motility （P = 0.048）. PIWI-LIKE 1 and PIWI-LIKE 2 mRNA expression exhibited a significant association with impaired sperm characteristics and may be a useful candidate for the evaluation of the impact of PIWI-LIKE 1-4 mRNA expression on male infertility.
