Malignant tumors of head and neck carcinomas are the sixth most common type of cancer. Current systemic therapies for cancer show side effects in normal tissues and short-term efficacy due to drug resistance. Consequently, there is much interest in identifying new drugs for cancer treatment. Crocin (an active ingredient of saffron) has been shown to have cytotoxic effects on cancer cell lines. ...

Abstract The transition from puddled-transplanted rice ( Oryza sativa L.) (PTR) to direct-seeded (DSR) is gaining popularity in central China. In contrast, the PTR system most common practice southwest Weeds are a major problem paddy fields of DSR systems, and herbicides widely used for weed control. However, increased frequency rate herbicide use leads rapid evolution resistance. Smallflower u...

  Background : Hydronephrosis (HN) or calycial dilatation is the most common prenatal urologic abnormality. The aim of this study was to identify the possible changes in demographic and clinical manifestations of infantile HN in previously and recently diagnosed patients.   Methods : 193 children with infantile HN admitted to Ali-asghar Children's Hospital in two different periods (group 1 1997...

This paper is a sequel to Curtis [7], where the Held group was constructed using a 7-modular monomial representation of 3·A7, the exceptional triple cover of the alternating group A7. In this paper, a 5-modular monomial representation of 2·HS:2, a double cover of the automorphism group of the Higman–Sims group, is used to build an infinite semi-direct product P which has HN, the Harada– Norton ...

1. In the leech, synaptic transmission between heart interneurons (HN cells) and between HN cells and heart motor neurons (HE cells) is blocked by bicuculline methiodide. 2. Gamma-aminobutyric acid, when applied focally onto the somata of HN cells or when added to the superfusate, has no effect on the membrane potential of HN cells. 3. Both acetylcholine (ACh) and the ACh agonist carbachol hype...

The nucleotide sequence of the haemagglutinin-neuraminidase (HN) gene of Newcastle disease virus (NDV) has been determined. The HN gene is 2031 nucleotides long, approximately 13.5% of the viral genome. The nucleotide sequence contains a single long open reading frame which would encode a protein of 577 amino acids, with a mol. wt. of 63,149. This is in good agreement with estimates of the mole...

We isolated, purified, and characterized the hemagglutinin-neuraminidase (HN) of human parainfluenza virus type 1, with the ultimate goal of producing crystals suitable for three-dimensional X-ray structure analysis. Pronase was used to cleave the globular head of the HN molecule directly from virus particles, forming HN monomers and dimers. The purified dimers retained neuraminidase and hemads...

Current management practices for hyponatremia (HN) are incompletely understood. The HN Registry has recorded diagnostic measures, utilization, efficacy, and outcomes of therapy for eu- or hypervolemic HN. To better understand current practices, we analyzed data from 3087 adjudicated adult patients in the registry with serum sodium concentration of 130 mEq/l or less from 225 sites in the United ...

Objective: Bryonia aspera (Stev. ex Ledeb) is a plant that grows in northeast of Iran. In the present study, cytotoxic and apoptogenic properties of B. aspera root extract was determined against HN-5(head and neck squamous cell carcinoma) and Hela (cervix adenocarcinoma) cell lines. Materials and Methods: HN-5 and Hela cell lines were cultured in DMEM medium and incubated with different concent...

Background: Newcastle disease virus (NDV) is a dangerous viral disease, infecting a broad range of birds, and has a fatal effect on the poultry industries. The attachment and consequently fusion of the virus to the host cell membrane is directed by the two superficial glycoproteins, the hemagglutinin-neuraminidase (HN) and the fusion (F) which is considered as the important tar...
