BACKGROUND 9b is an accessory protein of the SARS-CoV. It is a small protein of 98 amino acids and its structure has been solved recently. 9b is known to localize in the extra-nuclear region and has been postulated to possess a nuclear export signal (NES), however the role of NES in 9b functioning is not well understood. PRINCIPAL FINDINGS/METHODOLOGY In this report, we demonstrate that 9b in...

The red imported fire ant (RIFA), Solenopsis invicta, is an invasive species, accidentally introduced in the United States that can cause painful (sometimes life-threatening) stings to human, pets, and livestock. Their colonies have two social forms: monogyne and polygyne that have a single and multiple functional queens, respectively. A major gene (Gp-9), identified as a putative pheromone-bin...

Motivated by the problem of existence Kähler–Einstein edge metrics, Cheltsov and Rubinstein conjectured K-polystability asymptotically log Fano varieties with small cone angles when anti-log-canonical divisors are not big. Cheltsov, Zhang proved it affirmatively in dimension 2 irreducible boundaries except for type (I.9B.$n$) $1 \leq n 6$. Unfortunately, Fujita, Liu, Süß, Zhuang recently showed...

A simple observational approach for studying the response of the diamondback moth (DBM), Plutella xylostella (L.), to environmental gradients including latitude, insecticide application and climate change, was developed in this study. Insecticide resistance and carboxylesterase frequency in DBM collected in 1979/1980 and 1986/1987 were selected as two ecological variables for analysing and defi...

Coronaviruses (CoV) have recently emerged as potentially serious pathogens that can cause significant human morbidity and death. The severe acute respiratory syndrome (SARS)-CoV was identified as the etiologic agent of the 2002-2003 international SARS outbreak. Yet, how SARS evades innate immune responses to cause human disease remains poorly understood. In this study, we show that a protein en...

Background: Growth differentiation factor -9B (GDF-9B) is an oocyte derived growth factor, this protein is essential for development of ovarian follicles and act mainly by binding to its receptor on the surface of granulosa cells. The effect of this factor on the growth of follicles in various developmental stages particularly primordial and primary follicles is unknown. The aim of this study w...

Growth differentiation factor-9 (GDF-9) is a transforming growth factor-b (TGF-b) family member which is expressed in the oocytes in mouse ovaries (McGrath, S.A., Esquela, A.F., Lee, S.J., 1995. Oocyte-specific expression of growth/differentiation factor-9. Mol. Endocrinol. 9, 131-136). GDF-9 is indispensable for normal folliculogenesis since female mice deficient for the GDF-9 gene are inferti...
