BACKGROUND Most mammals experience cardiac arrest during hypothermia. In contrast, hibernators remain in sinus rhythm even at body temperatures of 0°C. OBJECTIVES The purpose of this study was to quantify electrical activity and connexin expression in the heart of hibernating Siberian ground squirrel Citellus undulatus. METHODS Optical imaging and microelectrode recordings were conducted in Lan...
The present study was conducted at the Biotechnology Laboratory, Biotechnology Division, Bangladesh Agricultural Research Institute (BARI), Gazipur during the period from September 2004 to June 2005 to investigate the effect of different concentrations of BAP and NAA on virus free plant regeneration, shoot multiplication and different concentrations of IBA and IAA on in vitro root formation of ...
در این پژوهش بمنظور تولید گیاهان خودریشه برخی از ارقام مهم گلابی ایران چندین آزمایش بصورت جداگانه انجام گرفت. در مرحله اول بمنظور تعیین ریزنمونه و تیمار ضدعفونی مناسب در چهار رقمِ سبری، نطنز، شکری و ویلیامز از دو ریزنمونه جوانه و قلمه گره ای و برای هر کدام دو غلظت متفاوت هیپوکلریت سدیم مورد استفاده قرارگرفت. ریزنمونه جوانه ضدعفونی شده با هیپوکلریت سدیم یک درصد تیمار مناسبی بود. در مرحله دوم اثر ...
In this study the effect of growth regulators in different concentrations were tested for shoot and root development micropropagation pomegranate with nodal explants. The explants collected morning, third node from tip. healthy plants which authenticated. For MS media was supplemented alpha-naphthalene acetic acid (NAA), indole-3-butyric-acid (IBA), 6-benzyl aminopurine (BAP) kinetin their comb...
5'-Methylthioadenosine (MTA) nucleosidase (MTN) plays a key role in the methionine (Met) recycling pathway of plants. Here, we report the isolation of the 1158 bp full-length, cDNA sequence encoding tetraploid black locust (Robinia pseudoacacia L.) MTN (TrbMTN), which contains an open reading frame of 810 bp that encodes a 269 amino acid protein. The amino acid sequence of TrbMTN has more than ...
OBJECTIVE Arteriogenesis is strongly dependent on the recruitment of leukocytes, especially monocytes, into the perivascular space of growing collateral vessels. On the basis of previous findings that platelets are central players in inflammatory processes and mediate the recruitment of leukocytes, the aim of this study was to assess the role of platelets in a model of arterial remodeling. AP...
We report a novel optical biosensor platform using near-infrared fluorescent single-walled carbon nanotubes (SWNTs) functionalized with target-recognizing aptamer DNA for noninvasively detecting cell-signaling molecules in real time. Photoluminescence (PL) emission of aptamer-coated SWNTs is modulated upon selectively binding to target molecules, which is exploited to detect insulin using an in...
As a consequence of restrictions on the use of preparations containing synthetic auxins in nursery production, there is a necessity to replace them with more environmentally friendly biopreparations efficiently stimulating plant growth. The aim of the presented experiment was to compare the effects of the synthetic auxin indole3-butyric acid (IBA) and the biostimulator Goteo on the rooting of n...
Population divergence in geographic isolation is due to a combination of factors. Natural and sexual selection may be important in shaping patterns of population differentiation, a pattern referred to as 'isolation by adaptation' (IBA). IBA can be complementary to the well-known pattern of 'isolation by distance' (IBD), in which the divergence of closely related populations (via any evolutionar...
In vitro rooting response and indole-3-acetic acid (IAA) levels were examined in two genetically related dwarfing apple (Malus pumila Mill) rootstocks. M.26 and M.9 were cultured in vitro using Linsmaier-Skoog medium supplemented with benzyladenine (BA), indole-3-butyric acid (IBA), and 1,3,5-trihydroxybenzoic acid (PG). Rooting response was tested in Lepoivre medium supplemented with IBA and P...
