Proteinase K is widely used in tests for the presence of infectious prion protein causing fatal spongiform encephalopathies. To investigate possible interactions between the enzyme and the functionally important N-terminal prion domain, we crystallized mercury-inhibited proteinase K in the presence of the synthetic peptides GGGWGQPH and HGGGW. The octapeptide sequence is identical to that of a ...

The objective of the present study was to conduct DNA based genotyping analysis for hybrid identification in maize (Zea mays L.) using DNA fingerprinting technology. To achieve this random amplified polymorphic DNA (RAPD) analysis was employed. A total of 40 random tenmer primers were surveyed. Of these, OPR-03, OPR-11 and OPT-06 were polymorphic which not only verified the purity among three l...

A new class of bimetallic isopropoxides of nickel(II) with niobium and tantalum with the general formula, Ni[M(OPr')6]2, (where M = Nb or Ta) have been synthesized by the reaction of nickel chloride isopropanolate, NiCl2-A:Pr'OH, with potassium hexaisopropoxy metalates, KM(OPr')6, (M = Nb or Ta) in the molar ratio 1:2. These derivatives have been characterized by elemental analyses, molecular w...

BACKGROUND AND OBJECTIVES Inappropriately high left ventricular mass (iLVM) is known to be related to cardiovascular prognosis. A non-dipper pattern has a greater mean left ventricular (LV) mass than the dipper pattern in hypertensive patients. However, the appropriateness of LV mass in dipper or non-dipper patterns has not been adequately investigated. The aim of this study was to define the r...

INTRODUCTION Nociceptive pain is one of the most common types of pain that originates from an injury involving nociceptors. Approximately 60% of the knee joint innervations are classified as nociceptive. The specific biological mechanism underlying the regulation of nociceptors is relevant for the treatment of symptoms affecting the knee joint. Intra-articular administration of exogenous hyalur...

Tin and titanium pentenoate have been prepared from tin(IV) butoxide and titanium (IV) isopropoxide in alcohol and 3-pentenoic acid. Reactions of Sn(OBu n )4 and Ti(OPr i )4 with 3-pentenoic acid in 1:1 molar ratio were studied in butanol and propanol solution at room temperature by sol-gel process. The complexations were investigated by 13 C, 1 HNMR and FT-IR spectroscopy. 13 C{ 1 H}, 1 H-NMR ...

background : bacterial infections in burn and wound patients are common and difficult to control. the aim of the current study was to evaluate the ability of full length oprf to elicit the production of protective igg in mice burn wound sepsis model against p. aeruginosa infection. methods : oprf protein was expressed and purified by ni-nta. the purified protein as used to immunize balb/c mice....

Optical pattern recognition (OPR) has the advantage of single intensity detection ability for low-cost terahertz (THz) systems imaging or security checks. However, conventional 4f-system-based OPR is limited by paraxial approximation and bulky device volumes THz applications. Here, a full-diffraction-based 4f-less method proposed using complex-amplitude-modulating metasurface, which valid with ...

BACKGROUND An efficient oocyte cryopreservation method is mandatory to establish a successful egg-banking programme. Although there are increasing reports showing good clinical outcomes after oocyte cryopreservation, there is still a lack of large controlled studies evaluating the effectiveness of oocyte cryo-banking. In this study, we aimed to compare the outcome of vitrified-banked oocytes wi...

Aim: The progesterone’s optimal route for luteal phase support (LPS) in frozen-thawed embryo transfer (FET) cycles is controversial. This study investigates the effect of three treatment regimens progesterone: vaginal, oral, and subcutaneous form LPS FET cycles.
 Material Method: Blastocyst cryopreserved utilizing subcutaneous, or oral forms progesterone between December 2018 May 2020 were...
