The Drosophila testis has been fundamental to understanding how stem cells interact with their endogenous microenvironment, or niche, to control organ growth in vivo. Here, we report the identification of two independent alleles for the highly conserved tumor suppressor gene, Retinoblastoma-family protein (Rbf), in a screen for testis phenotypes in X chromosome third-instar lethal alleles. Rbf ...

We have shown that duct modeling using the generalized RBF neural network (DM RBF), which has the capability of modeling the nonlinear behavior, can suppress a variable-frequency narrow band noise of a duct more efficiently than an FX-LMS algorithm. In our method (DM RBF), at first the duct is identified using a generalized RBF network, after that N stage of time delay of the input signal to th...

In an RBF implementation of the Bayesian equalizer the RBF centers are placed at equ...

Fiji’s central bank, the Reserve Bank of Fiji (RBF) since its inception in 1983, has been pursuing monetary policy with the mandated objectives of economic growth with price stability and an adequate level of exchange reserves. In 1988, as part of financial sector reforms, RBF discontinued the use of direct instruments and switched on to employment of indirect instruments for influencing intere...

Renal blood flow (RBF) can be reduced in rats and rabbits by up to 40% without significant changes in renal tissue Po(2). We determined whether this occurs because renal oxygen consumption changes with RBF or due to some other mechanism. The relationships between RBF and renal cortical and medullary tissue P(O(2)) and renal oxygen metabolism were determined in the denervated kidneys of anesthet...

Glomerular filtration rate (GFR) and renal blood flow (RBF) are normally kept constant via renal autoregulation. However, early diabetes results in increased GFR and the potential mechanisms are debated. Tubuloglomerular feedback (TGF) inactivation, with concomitantly increased RBF, is proposed but challenged by the finding of glomerular hyperfiltration in diabetic adenosine A(1) receptor-defic...

مگس مینوز سبزی و صیفی Liriomyza sativae Blanchard ، از مهم­ترین آفات ‌های گلخانه ای فضای باز، محسوب می شود. با توجه به توصیه کاربرد حشره­ کش تیوسیکلام جهت مدیریت آفت مزبور، در پژوهش حاضر، اثرات کشندگی زیرکشندگی(5/131:LC30، 1/87:LC20، 15/49:LC10 میلی گرم ماده موثره بر لیتر) حشره ­کش (اویسکت®SP50%) روی فراسنجه ­های زیستی این شرایط آزمایشگاهی مورد ارزیابی قرار گرفت. روش استفاده انجام آزمایش­ها غوط...

Both Staphylococcus aureus and S. epidermidis are capable of forming biofilm on biomaterials. We used Tn917 mutagenesis to identify a gene, rbf, affecting biofilm formation in S. aureus NCTC8325-4. Sequencing revealed that Rbf contained a consensus region signature of the AraC/XylS family of regulators, suggesting that Rbf is a transcriptional regulator. Insertional duplication inactivation of ...
