Seven Swedish domestic goats (Capra hircus, 2–3 years) and their kids (37 ± 4 days) were subjected to indoor temperatures above 30°C during 15 days (periods H1–H4; periods without heat C1, C2) s...
Champion, Hunter C., Trinity J. Bivalacqua, David G. Lambert, Rasheed A. Abassi, and Philip J. Kadowitz. Analysis of vasoconstrictor responses to histamine in the hindlimb vascular bed of the rabbit. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R1179–R1187, 1999.—Hemodynamic responses to histamine were investigated in the anesthetized rabbit. Intravenous injections of histami...

Let h1, · · · , hn be positive integers. We study new sums m(h1, · · · , hn) = h1−1 ∑ r1=0 · · · hn−1 ∑ rn=0 min { r1 h1 , · · · , rn hn } and M(h1, · · · , hn) = h1−1 ∑ r1=0 · · · hn−1 ∑ rn=0 max { r1 h1 , · · · , rn hn } , the first of which times h1 · · ·hn is the number of lattice points in a pyramid of dimension n + 1. We show that m(h1, · · · , hn) (h1 − 1) · · · (hn − 1) = 1 + ∑ ∅6 =I⊆{1...
The Horrocks-Mumford bundle E is a famous stable complex vector bundle of rank 2 on 4-dimensional complex projective space. By construction, E has a natural Hermitian metric h1. On the other hand, stability implies the existence of a Hermitian-Einstein metric in E which is unique up to a positive scalar. Now the obvious question is if h1 is in fact the Hermitian-Einstein metric. In this note we...
A newly identified costimulatory molecule, programmed death-1 (PD-1), provides a negative signal that is essential for immune homeostasis. However, it has been suggested that its ligands, B7-H1 (PD-L1) and B7-dendritic cells (B7-DC; PD-L2), could also costimulate T cell proliferation and cytokine secretion. Here we demonstrate the involvement of PD-1/B7-H1 and B7-DC interaction in the developme...
Glutamate works as a major excitatory neurotransmitter in the vertebrate retina. Whole-cell recordings made from isolated carp cone horizontal cells (H1 cells) showed that Nmethyl-D-aspartate (NMDA), co-applied with glycine, induced inward currents that were blocked by the NMDA receptor competitive antagonist D -2-amino-5-phosphonopentanoate ( D -AP5) and 5,7-dichlorokynurenic acid (DCKA), a se...
The methylated DNA binding protein-2-H1 (MDBP-2-H1), present in rooster liver, is a member of the histone H1 family which inhibits transcription by binding selectively to methylated promoters. Here we have determined the primary structure of MDBP-2-H1. A comparison between histone H1 and MDBP-2-H1 was achieved by analyzing reversed phase HPLC-purified and V8-digested proteins by mass spectromet...
زمینه و هدف: ویروس آنفلوانزای تیپ a باعث ایجاد بیماری در انسان، طیور و حیوانات پست می شود و اخیرا گزارش هایی مبنی بر انتقال تحت تیپ h9n2 و h5n1 از طیور به انسان به چاپ رسیده است. هدف از این تحقیق، بررسی وجود آنتی بادی h9n2 در افراد مرتبط با صنعت پرورش طیور است که به این وسیله احتمال انتقال و ابتلا به این سویه مورد بررسی قرار می گیرد. مواد و روش ها: در این مطالعه آزمایشات سرولوژی بر روی 100 نمو...
