In a study of gerbils with contrasting social and mating systems (group-living monogamous Mongolian gerbil Meriones unguiculatus, solitary nonterritorial promiscuous midday jird M. meridianus, and solitary territorial promiscuous pale gerbil Gerbillus perpallidus), we employed part ner pref ere nee tests (PPTs) to assess among-species variation in sociability and pair-bonding patterns and tested whether the nature of contact between individuals: direct contact (DC) versus nondirect contact (NDC) affected our results. We measured male pref ere nces as the time: 1) spe nt alone, 2) with familiar (partner), and 3) unfamiliar (stranger) female in the 3-chambered apparatus. Gerbil species differed strongly in sociability and male partner preferences. The time spent alone was a reliable indicator of species sociability indepe ndent of the nature of con tact, whereas the pattern and level of betwee n-species differe nces in male partner preferences depended on con tact type: DC PPTs, un like NDC-tests, discriminated well betwee n monogamous and promiscuous species. In the DC-tests, stranger-directed aggression and stranger avoidanee were observed both in the highly social monogamous M. unguiculatus and the solitary territorial promiscuous G. perpallidus, but not in the non territorial promiscuous M. meridianus. In M. unguiculatus, stranger avoidanee in the DC-tests increased the time spent with the partner, thus providing evidence of a partner preference that was not found in the NDC-tests, whereas in G. perpallidus, stran ger avoidance in creased the time spe nt alone. This first comparative experimental study of partner prefere nces in gerbils provides new in sights into the in terspecific variation in gerbil sociality and mating systems and sheds light on behavioral mechanisms un derlyi ng social fidelity and pair-b on ding.

A descriptive survey was conducted in Sulangan, Guiuan, eastern Samar to describe the status of Caulerpa as the potential for aquaculture. Identification of species with natural populations, species with massive natural populations and the edible species favoured by the local residents were the specific objectives of this study. The observed massive population with 85% cover in 100 sqm was a combination of the nine Caulerpa species, which are C. racemosa, C. lentillifera, C. chemnitzia var. peltata, C. cylindracea, C. brachypus, C. macrophysa, C. microphysa, C. serrulata and C. sertularioides. The majority, 98%, was composed of C. racemosa and C. lentillifera, while other species were observed in one to two feet of stolon length underneath the two species. C. racemosa and C. lentillifera were identified as the most locally consumed species by 100% of the respondents, but C. lentillifera was most preferred by 98% due to its thinner ramuli over C. racemosa. Results revealed that Sulangan is a potential area for Caulerpa aquaculture with reference to the specific location and specifically to C. racemosa and C. lentillifera. Preliminary trials on Caulerpa aquaculture can be initially introduced;however, seasonality should be validated.

Writing at the nanoscale using the desorption of oxygen adatoms from the oxygen-rich MoO2＋x/Mo（110） surface is demonstrated by scanning tunnelling microscopy （STM）. High-temperature oxidation of the Mo（110） surface results in a strained, bulk-like MOO2（010） ultra-thin film with an O-Mo-O trilayer structure. Due to the lattice mismatch between the Mo（110） and the MOO2（010）, the latter consists of well-ordered molybdenum oxide nanorows separated by 2.5 nm. The MoO2（010）/Mo（110） structure is confirmed by STM data and density functional theory calculations. Further oxidation results in the oxygen-rich MoOa^x/Mo（110） surface, which exhibits perfectly aligned double rows of oxygen adatoms, imaged by STM as bright protrusions. These adatoms can be removed from the surface by scanning （or pulsing） at positive sample biases greater than 1.5 v. Tip movement along the surface can be used for controlled lithography （or writing） at the nanoscale, with a minimum feature size of just 3 nm. By moving the STM tip in a predetermined fashion, information can be written and read by applying specific biases between the surface and the tip.

Resistance to cancer therapy continues to be a major limitation for the successful treatment of cancer. There are many published studies on therapy resistance in breast and prostate cancers; however, there are currently no data on molecular markers associated with resistance. The conflicting data were reported regarding the AKT/m-TOR signaling pathway components as markers predicting resistance. The AKT/m-TOR signaling pathway is involved in the development of many human cancers; its activation is related to cell proliferation, angiogenesis, apoptosis, as well as to therapy resistance. Molecular alterations in the AKT/m-TOR signaling pathway provide a platform to identify universal markers associated with the development of resistance to cancer therapy.

An unusual feature of the saline stratified lakes that were formed due to ongoing postglacial uplift on the White Sea coast is the presence of several differently colored thin layers in the zone with sharp gradients. Colored layers in five lakes at various stages of separation from the sea were investigated using optical microscopy, spectrophotometry, spectrofluorimetry, and photobiology. The upper greenish colored layer located in the aerobic strata of all lakes near the compensation depth of 1% light penetration contains green algae. In the chemocline, another layer, brightly green, red or pink, is dominated by mixotrophic flagellates. despite the very low light intensities and the presence of H 2 S, active photosynthesis by these algae appears to be occurring, as indicated by high values of the maximum quantum yield of primary photochemistry, electron transport activity, photosynthetic activity of photosystem II, the fraction of active centers, and low values of heat dissipation. In the reduced zone of the chemocline, a dense green or brown suspension of anoxygenic phototrophs(green sulfur bacteria) is located.

BACKGROUND： In recent years, an adaptive endoplasmic reticulum （eR） stress response has been actively investigated. The eR membrane, isolated from the intact and regenerating liver, may be an appropriate model for investigating the association between structural and functional characteristics of eR in vivo and their corresponding behavioral characteristics in vitro. The rate of lipid synthesis and that of intracellular lipid exchange between the eR and cytosol were investigated in the intact and regenerating liver （13 h after partial hepatectomy）. Particularly, membrane characteristics, surface potential, and glucose 6- phosphatase （G6Pase） activity were investigated, along with the degradation rate of G6Pase in vitro, which was estimated by the loss of G6Pase activity, formation of lipid peroxides, and size of excreted membrane vesicles. MeTHODS： The rate of lipid synthesis was determined by measuring the intensity of radioactive precursor （C^14-sodium acetate） in different fractions of lipids （phospholipids, non-esterified fatty acids, and triacylglycerides） after 30 min exposure. The rate of lipid metabolism was assessed by measuring the quantity oflipids with radioactive labels emerging in the cytosol of hepatocytes （CPM）. viscosity and surface potential were determined by fluorescent probes. ReSULTS： It was observed that after 13 h of partial hepatectomy, the rate of lipid synthesis in the eR of hepatocytes in the regenerating liver was 3 times lower than that in eR ofhepatocytes in the intact liver, wherein the rate of incorporation of newly synthesized lipids in cytosol was several times higher in the regenerating liver. Increase in the rate of exchange of neutral lipids in cells of the regenerating liver was accompanied by lipid reconstruction in the eR, changing the structural and functional characteristics of the membrane. Such membrane rebuilding also contributed to the rate of degradation of the eR in vitro, which that must be taken into account during d
