Alpha s1-, alpha s2-, beta- and kappa-caseins from Somali camels (Camelus dromedarius) were purified by acid precipitation at pH 4.4, crudely separated into an alpha-CN and a beta-CN fraction and further purified by reversed-phase HPLC. Fragments of tryptic digests were sequenced. Amino acid patterns obtained were used to screen a cDNA library constructed from mRNA from lactating udder tissue. ...
To examine the influence of acoustic experience on the development of the mammalian auditory brain stem, darkly pigmented ferrets were reared with a plug inserted in the right outer ear. The plugs were first inserted on postnatal day 23-34 and produced a variable, frequency-dependent attenuation of up to 60 dB. Between 3-15 months after the ear plug was begun, animals were prepared for physiolo...
Abstract Native polyacrylamide gel electrophoresis (PAGE) is a powerful technique for protein complex separation that retains both their activity and structure. In photosynthetic research, native-PAGE particularly useful given complexes are generally large in size, ranging from 200 kD to 1 MD or more. Recently, it has been reported the addition of amphipol A8-35 solubilized samples improved sta...
فرض کنید g یک گروه متناهی باشد. در این پایان نامه نشان می دهیم اگرگراف اول gباگراف اول cn(2) برای n>=3 های فردبرابرباشد، آن گاه g یک ترکیب نا آبلی منحصر به فرد یکریخت با cn(2) دارد. در نتیجه cn(2) با گراف اولش شبه تشخیص پذیر است و در ادامه شبه تشخیص پذیری cn(4) را برای n >=17 های فرد, با گراف اول نشان می دهیم.
BACKGROUND The choice of the correct concentration of potential uremic toxins for in vitro, ex vivo, and in vivo experiments remains a major area of concern; errors at this level might result in incorrect decisions regarding therpeutic correction of uremia and related clinical complications. METHODS An encyclopedic list of uremic retention solutes was composed, containing their mean normal co...
Multiple-input multiple-output (MIMO) spatial multiplexing achieves very high spectrum efficient signal transmissions in a cellular network (CN). However, this is only possible when the received signal-to-interference plus noise power ratio (SINR) is high enough. In a conventional CN, multiple antennas are colocated at each based station (BS) and hence, the throughput of a mobile terminal (MT) ...
Cyanoborane adducts of the Lewis acids B(CN)3, BF(CN)2, and BH(CN)2 with pyridine 4-cyanopyridine have been obtained in high yields. The syntheses were accomplished by oxidation readily available potassium salts cyano(hydrido)borate anions [BH(CN)3]− (MHB), [BFH(CN)2]− (FHB), [BH2(CN)2]− (DHB) bromine presence respective derivative C5H5N or 4-CN-C5H4N as starting material. All six cyanoborane c...
A new fast and reliable reversed-phase high-performance liquid chromatographic method is proposed for quantifying all the major casein fractions during cheese proteolysis as an alternative to more complex methodologies. Excellent separation of caseins, para-κ-casein (ρ-κ-CN), αs1-casein (αs1-CN), αs1-I-casein (αs1-I-CN), αs2-casein (αs2-CN), β-casein (β-CN) was achieved, in terms linearity, rep...
Native ovoperoxidase exhibited an optical absorption spectrum with certain similarities to lactoperoxidase, but not horseradish peroxidase, over the pH range 4.5-11.5. Ovoperoxidase had three distinct spectral forms dependent on pH, with transitions at apparent pKa values of 6.6 and 3.0. Complexes of ovoperoxidase with CN-, N3-, F-, or when reduced and ligated to carbon monoxide, CN-, or pyridi...
