Administration of the petroleum ether extract of leaves of P. minima (collected from India) to female albino rats altered their regular cyclicity. Rats treated with the extract (p.o.) exhibited variations in uterine and ovarian weights and caused significant histopathological changes in the histoarc...

We report the transmittance of Antarctic snow as a function of the thickness of snow layers, in the range between 350 and 900 nm. Samples were studied near Scott Base, Ross Island, and data are presented for measurements made in early December 1996. The transmittance followed the two flux theoretica...

This paper is the first of a two-part paper on the application of selective direct control of loads for small-disturbance angle stability enhancement in power systems. The change in the utility business model and developments in enabling technologies open up new possibilities for power system reliab...

Inorganic trivalent arsenicals are vicinal thiol-reacting agents, and dithiothreitol (DTT) is a well-known dithiol agent. Interestingly, both decreasing and increasing effects of DTT on arsenic trioxide-induced apoptosis have been reported. We now provide data to show that, at high concentrations, D...

Prophenin-2 (PF-2) is a cathelicidin, 97-amino-acid antimicrobial protein stored in neutrophil secondary granules. PF-2 is expressed specifically in porcine immature myeloid cells; however, little is known about its regulation. In this study, we characterized the 5' regulatory regions of the PF-2 ge...

The LD50 value of an injected leaf extract of Pongamia glabra [P. pinnata] was 0.05 ml of 5% leaf extract for adult males of Periplaneta americana. In extract-treated males, the mushroom-shaped accessory reproductive gland exhibited disintegration of the epithelial layer and the lumen consisted of t...

The porcine antimicrobial peptide, PR-39, has several activities beyond its function of killing bacteria. Here we report that PR-39 alters macrophage viability by inhibiting apoptosis, which was induced by nutrient depletion, LPS stimulation or camptothecin treatment. This antiapoptotic effect was p...

We have investigated the levels of nuclear protein acetylation in u.v.-irradiated human fibroblasts. Initially, we measured the levels of acetylation in total acid-soluble nuclear proteins and observed two distinct differences between the irradiated and unirradiated (control) cells. Immediately afte...

Hepcidin is a liver-expressed iron-regulating hormone that also is an antimicrobial peptide. Here we report the full-length cDNA sequences of porcine hepcidin and liver-expressed antimicrobial peptide-2 (LEAP-2). Porcine hepcidin and LEAP-2 cDNA sequences contain 411 and 525 bp, and encode predicted...

Androgen dependent epididymal proteins act as antigen to produce autoantibodies and affect normal fertility. In the present study, epididymal proteins were analyzed during the time of sexual maturation and their androgen dependency was studied in male albino mice. Epididymis of 21 days (Pre-pubertal...

Peptidoglycan recognition proteins (PGRPs) are a group of newly identified proteins with emerging functions in mammalian innate immunity. Here we report the identification and characterization of two long isoforms of porcine PGRP. Their complete cDNA sequences encode predicted peptides of 252 and 59...

BACKGROUND: The study reported here was undertaken to assess the presence of antibodies to Sarcocystis neurona in the serum of horses of North American origin that had been relocated for 1 year or more to India (ie, outside of the known endemic areas for S. neurona). HYPOTHESIS: The presence or abse...

We have investigated the level of 'early' DNA repair synthesis in nucleosome subpopulations, varying in histone acetylation, from normal human fibroblasts treated with sodium butyrate. We find that repair synthesis occurring during the first 30 min after UV irradiation is significantly enhanced in h...

Triggering receptor expressed on myeloid cells 1 (TREM-1) is a type I transmembrane receptor of the immunoglobulin superfamily expressed predominantly on neutrophils and monocytes. TREM-1 induces the expression of inflammatory cytokines and adhesion molecules, and augments osteoclast, microglia, oli...

Antimicrobial peptides are important host-defense molecules of innate immunity. Cathelicidins are a diverse family of potent, rapidly acting and broadly effective antimicrobial peptides, which are produced by a variety of cells. This review examines the classification, antimicrobial spectrum, mechan...

Paclitaxel, one of the most commonly prescribed chemotherapeutic agents, is active against a wide spectrum of human cancer. The mechanism of its cytotoxicity, however, remains controversial. Our results indicate that paclitaxel treatment increases levels of superoxide, hydrogen peroxide, nitric oxid...

In this second part of this paper, numerical simulations and test results have been presented on a 29-generator, 179-bus equivalent of the WECC system for both approaches of load modulation analysis developed in Part I. The accuracy of the robust performance analysis framework as well as the analysi...

Alkaline comet assay is a simple sensitive method for detecting DNA strand breaks. However, at the time of cell lysis, only a fraction of the entire DNA damage appears as DNA strand breaks, while some DNA strand breaks may have been rejoined and some DNA lesions may still remain unexcised. We showed...

Contained in this report is a review of available data on pituitary cytokines in domestic species of agricultural importance. The concept is advanced that the pituitary gland is essential to appropriate generation of host defense mechanisms and thus should be considered among other tissues contribut...

Titanium-catalyzed hydroamination of 1,4- and 1,5-diynes by primary amines leads to imino-alkynes that undergo in situ 5-endo dig and 5-exo dig cyclization reactions, respectively. The products are 1,2,5-trisubsituted pyrroles accessed directly from readily available diyne starting materials.

Plasmacytoid dendritic cells (pDCs) detect viruses in the acidified endosomes by means of Toll-like receptors (TLRs). Yet, pDC responses to certain single-stranded RNA (ssRNA) viruses occur only after live viral infection. We present evidence here that the recognition of such viruses by TLR7 require...

Triggering receptors expressed on myeloid cells (TREM) are a family of activating receptors expressed on neutrophils and monocytes. These receptors are involved in regulation of immunity by inducing the expression of inflammatory cytokines and adhesion molecules, augmenting dendritic cell maturation...

The fat body of Periplaneta americana usually contains trophocytes, urocytes and mycetocytes. The fat body showed some marked changes in insects injected with a sublethal concentration of Pongamia glabra [P. pinnata] leaf extract (0.05 ml of 5% concentration) through the intra-peritoneal membrane. I...
