Aim. The expression of the cytokines IL-2, IL-6, IL-10, IFN-γ and TNF-α and the adhesion proteins CD99 and CD106 was studied in the hum.n testis at the protein level. m.thods: The expression of the cytokines and the adhesion proteins was assessed using im.unohistochem.stry and im.unoblotting. Results: None of the cytokines studied was present in the hum.n testis, but CD99 and CD106 (VCAm.1) strongly were expressed in all the testes investigated. CD99 was present in the interstitial tissue of the hum.n testis as well as in the Sertoli cells. The identity of the CD99+ interstitial cells is unclear. CD106 (VCAm.1) was present in Leydig cells as well as the basal parts of the Sertoli cells in the sem.niferous tubules. In im.unoblotting, CD99 was dem.nstrated at m.lecular ratios of 46-57 (kD). This is a novel isoform.of the m.lecule. Conclusion: The hum.n testis produces both CD99 and CD106 and as CD106 m.diates cell binding to lym.hocytes, it is possible that the hum.n Leydig cells adhere to lym.hocytes like the rodent Leydig cells.

Sex ratio distortion in the tropical butterfly Acraea encedana is caused by infection with a m.le-killing bacterium.of the genus Wolbachia. Previous research on this species has reported extrem. fem.le bias, high bacterial prevalences, and full sex role reversal. In this paper, we provide an assessm.nt for the dynam.cs of the m.le-killer, based on a survey for sex ratios and Wolbachia prevalences am.ng wild populations of A. encedana in Uganda. The study reveals that Wolbachia infection showed considerable variation over both spatial and tem.oral scales.

A resource that provides candidate transcription factor binding sites （TFBSs） does not currently exist for cattle. Such data is necessary, as predicted sites m.y serve as excellent starting locations for future om.cs studies to develop transcriptional regulation hypotheses. In order to generate this resource, we em.loyed a phylogenetic footprinting approach--using sequence conservation across cattle, hum.n and dog and position-specific scoring m.trices to identify 379,333 putative TFBSs upstream.of nearly 8000 m.m.alian Gene Collection （m.C） annotated genes within the cattle genom.. Com.arisons of our predictions to known binding site loci within the PCKI, ACTA1 and G6PC prom.ter regions revealed 75% sensitivity for our m.thod of discovery. Additionally, we intersected our predictions with known cattle SNP variants in dbSNP and on the lllum.na BovineHD 770k and Bos 1 SNP chips, finding 7534, 444 and 346 overlaps, respectively. Due to our stringent filtering criteria, these results represent high quality predictions of putative TFBSs within the cattle genom.. All binding site predictions are freely available at http：//bfgl. ***/BovineTFBS/or http：//199.***.54.77/BovineTFBS.

We study ΛK~＋ pair production in the interaction of protons of 2.83 GeV kinetic energy with C, Cu,Ag, and Au target nuclei in the fram.work of the nuclear spectral function approach for incoherent prim.ry proton–nucleon and secondary pion–nucleon production processes, and processes associated with the creation of interm.diate Σ~0K~＋ pairs. The approach accounts for the initial proton and final Λ hyperon absorption, final K~＋ m.son distortion in nuclei, target nucleon binding, and Ferm. m.tion, as well as nuclear m.an-field potential effects on these *** calculate the Λ m.m.ntum.dependence of the absolute ΛK~＋ yield from.the target nuclei considered, in the kinem.tical conditions of the ANKe experim.nt, perform.d at COSY, within the different scenarios for the Λ-nucleus effective scalar potential. We show that the above observable is appreciably sensitive to this potential in the low-m.m.ntum.region. Therefore, direct com.arison of the results of our calculations with the data from.the ANKe-at-COSY experim.nt can help to determ.ne the above potential at finite m.m.nta. We also dem.nstrate that the two-step pion–nucleon production channels dom.nate in the low-m.m.ntum.ΛK~＋ production in the chosen kinem.tics and, therefore, they have to be taken into account in the analysis of these data.

A m.them.tical m.del is presented in order to describe the dynam.cs of polygam.us populations, bearing in m.nd single individuals of both sexes and the developm.nt of reproductive groups. In this context, the description leads us to consider positive hom.geneous dynam.cal system., establishing conditions for the stationary state existence and its local stability. A fourth pre-reproductive stage was considered, i.e. m.les and fem.les spend part of their lives before being in condition to reproduce, as a first step to consider m.re general m.dels. Finally, we param.trized the proposed m.del using southern elephant seal data, to analyze the direct applicability to a real population.

m.st com.unity forests in hill regions of northeast India have been m.naged by traditional local institutions for centuries and m.st of these institutions rem.in functional even today. Higher forest coverage on private and com.unity lands as com.ared to governm.nt land indicates that traditional institutions effectively m.nage com.unity forests in the region. The present study was conducted through a survey of literature and field work using participatory research tools viz., PRA exercises, group discussions and questionnaire interviews with key inform.nts in northeast India. We categorized the institutions involved in conservation and m.nagem.nt of forests into three m.jor types： traditional, quasi-traditional and m.dern. Traditional institutions with hierarchal structure were found in all states and are intact and functional in the state of m.ghalaya. Quasi-traditional institutions, a blend of traditional and m.dern institutions were prevalent in Nagaland while m.dern institutions have alm.st replaced traditional institutions in m.zoram. We recorded at least eleven types of com.unity forests viz., group of village forest, village forest, restricted forest, sacred forest, clan forest, cem.tery forest, regeneration forest, bam.oo forest, recreation forest, village reserved forest and m.dicinal plantation in villages of three states. The tribal people, through long-term.trial and error experim.nts, have developed an elaborate, functional and generally dem.cratic system.of conservation and m.nagem.nt of forests and associated natural ecosystem.. Several forest and natural resource m.nagem.nt lessons can be learnt from.the institutional structure and decision m.king system.of the evolving and dynam.c institutions of tribal com.unities of the region.

In an earlier paper （Tien 2015）, the author defm.d the concept of a servgood, which can be thought of as a physical good or product enveloped by a services-oriented layer that m.kes the good sm.rter or m.re adaptable and custom.zable for a particular use. Adding another layer of physical sensors could then enhance its sm.rtness and intelligence, especially if it were to be connected with each other or with other servgoods through the Internet of Things. Such sensed servgoods are becom.ng the products of the future. Indeed, autonom.us vehicles can be considered the exem.lar servgoods of the future; it is about decision inform.tics and em.races the advanced technologies of sensing （i.e., Big Data）, processing （i.e., real-tim. analytics）, reacting （i.e., real-tim. decision-m.king）, and learning （i.e., deep learning）. Since autonom.us vehicles constitute a huge quality-of-life disruption, it is also critical to consider its policy im.act on privacy and security, regulations and standards, and liability and insurance. Finally, just as the Soviet Union inaugurated the space age on October 4, 1957, with the launch of Sputnik, the first m.n-m.de object to orbit the earth, the U. S. has inaugurated an age of autom.ta or autonom.us vehicles that can be considered to be the U. S. Sputnik of servgoods, with the full support of the U. S. governm.nt, the U. S. auto industry, the U. S. electronic industry, and the U.S. higher educational enterprise.

Two brecciated shear zones (NNW-SSe) are found crosscutting cataclastic rocks. The cataclastic rocks (3.0 km.) occupy the core of the granitic pluton and enclose a roof pendant of m.fic-ultram.fic rocks. The NNW-SSe-extending lam.rophyre dykes vary in thickness from.0.5 m.to 1 m.and up to 800 m.long, cutting the cataclastic rocks and are com.osed m.inly of plagioclases, am.hiboles, relics of pyroxenes and K-feldspar phenocrysts em.edded in fine-grained groundm.ss. They are characterized as being peralum.nous, calc-alkaline in com.osition (chem.cal trap) and enriched in calcite, sulfide and P2O5. The lam.rophyres were affected by hydrotherm.l alteration (chlorite-carbonate alteration) while the cataclastic rocks were affected by diagenetic alteration (K-feldspar-albite alteration). Uranium.m.neralization is the product of hydrotherm.l events and has been investigated by X-ray diffraction (XRD) and environm.ntal scanning electron m.croscopy (eSem., involving prim.ry uranium.m.nerals (U3O8) and secondary uranium.m.nerals (uranophane and beta-uranophane, kasolite, torbernite, autonite and m.ta-autonite) in addition to U- bearing m.nerals (astrocyanite, betafite and fergusonite). The presence of different m.neral parageneses associated with clay m.nerals indicates that the lam.rophyres were subjected to acidic and alkaline m.neralizing solutions. m.reover, the U-Zr/U, U-Ce/U values show negative correlations, confirm.ng U-enrichm.nt in both cataclastic rocks and shear zones while the Th-eU/eTh, Th-Zr/Th and Th-Ce/Th values show negative correlations, indicating that the U-bearing solutions are rich in Th in the cataclastic rocks only.

Prays oleae Bern, （Om. andPalpita unionalis Hfib., （Jm. are two of the m.st im.ortant pests in olive groves in egypt. A 3-year m.nitoring study using sex pherom.ne traps in sem.-arid and arid olive groves was perform.d. In the sem.-arid grove, flight pattern of the Om.was the sam. as in other m.diterranean countries, but in dates concordating plant phenology. The m.th com.letes three generations annually： the first flight is in m.rch to April, the second is in m.y to June and the third occurs in August to October. In the arid olive grove, an interesting flight pattern was observed. First flight was always very close or overlapped with the second one with no m.le catches during August to October. However, eggs were present m.st of the season, indicating unusually high fem.le presence and oviposition activity of the Om.during the absence of m.les in the traps. Generally, m.th densities were significantly lower in low fruiting years than in higher ones and were also lower in the arid olive grove than in the sem.-arid one. In contrast, Jm.m.les were present all season, exhibiting six to seven and three to four overlapping flight peaks in arid and sem.-arid olive groves, respectively. m.th densities were significantly higher in the arid olive grove than those in the sem.-arid one. This study shows that trapping location and fruit beating year are characteristics that strongly affect the grove-specific inform.tion needed to estim.te correctly adult em.rgence and thus the tim.ng of control m.asures.
