synthesis, cytotoxicity and antiviral activity of podophyllotoxin analogues modified in the e-ring.several podophyllotoxin derivatives modified in the e-ring were prepared and evaluated for their cytotoxicity on four neoplastic cell lines (p-388, a-549, ht-29 and mel-28) and for their antiherpetic activity against herpes simplex virus type ii. the trimethoxyphenyl moiety was oxidized to ortho-quinone and further condensed with diamines and enamines to form different heterocycles. most of the compounds maintained their cytotoxicity at the mum level and some of them showed antiherpetic activity ...200314575937
lifting the curtain of silence: survivors speak about rape behind bars.in the struggle to end sexual violence behind bars, personal stories of abuse serve as an important advocacy tool for organizations such as stop prisoner rape (spr). the first-person accounts of men and women who have endured this abuse help to personalize, and thereby, humanize the issue. statistics about the frequency of prisoner rape are powerful, but they can also be numbing, conveying the sense that nothing can be done to stop the problem. personal accounts in contrast, have an emotional im ...200314584537
herpes simplex virus ul14 protein blocks apoptosis.we report that an hsv-2 ul14 protein expressing cell line (14/hep-2) was more resistant to apoptosis induced by osmotic shock and certain drugs than its parental cell line. furthermore, hsv-1 ul14 protein deletion virus (ul14d) showed weaker inhibition of apoptosis compared to the rescued virus ul14r. the protein's anti-apoptotic function may derive from its heat shock protein-like properties.200314584616

the role of dendritic cells in immune responses against vaginal infection by herpes simplex virus type 2.herpes simplex virus type 2 is a leading cause of genital ulcers that affects more women than men worldwide. recent evidence indicates that protective immunity can be generated by specialized dendritic cells in the female genital mucosa. this article aims to provide an overview of the effector immunity required for protection from genital herpes, and to discuss the mechanism by which specific subsets of dendritic cells mediate induction of adaptive immunity following genital infection with herpe ...200314623018
the us3 protein kinase of herpes simplex virus attenuates the activation of the c-jun n-terminal protein kinase signal transduction pathway in infected piriform cortex neurons of c57bl/6 mice.stereotaxic microinjection of herpes simplex virus (hsv) into the mouse olfactory bulb resulted in infection of neurons of the piriform cortex. neurons infected with the wildtype hsv showed no evident phosphorylation of c-jun n-terminal protein kinase (jnk)/c-jun. in contrast, neurons infected with a us3 gene-disrupted mutant of the l1br1 virus displayed phosphorylated jnk/c-jun in a nuclear staining fashion. induction of neuronal apoptosis by the wildtype hsv was partially suppressed when compa ...200314623140
human immunodeficiency virus acquisition associated with genital ulcer disease and herpes simplex virus type 2 infection: a nested case-control study in rakai, uganda.to assess the timing of symptomatic genital ulcer disease (gud) relative to human immunodeficiency virus (hiv) seroconversion, we studied 248 case subjects who underwent hiv seroconversion and 496 hiv-negative control subjects, at 3 interview visits conducted at 10-month intervals: visit 1, before hiv acquisition; visit 2, after seroconversion; and visit 3, 10 months after detection of seroconversion. odds ratios (ors) and 95% confidence intervals (cis), for hiv acquisition, were estimated by lo ...200314624374
new options in herpes management.herpesviruses in the alpha group--hsv-1, hsv-2, and vzv (i.e., hsv-3)--are ubiquitous in american society. hsv-1 is associated primarily with herpes labialis, while hsv-2 is involved in about 70% of cases of genital herpes. varicellazoster virus causes chickenpox in unvaccinated children and others, and latent virus produces shingles later in life. since many patients with hsv-1 and hsv-2 infections are asymptomatic, testing is important in determining presence of the viruses. several antiviral ...200314626519
multiplex polymerase chain reaction for the detection of herpes simplex virus, varicella-zoster virus and cytomegalovirus in ocular specimens.a majority of ocular viral diseases are caused by herpes group of viruses. such infections, especially atypical herpetic keratitis, iridocyclitis and intra-ocular inflammations, can often present with overlapping clinical manifestations misleading the diagnosis. molecular techniques are most useful in such instances for an accurate and rapid diagnosis since conventional methods are time consuming and less sensitive. a multiplex pcr was developed and used for the detection of herpes simplex virus ...200314632159
herpes simplex virus type 1 infection associated with atrial myxoma.some findings suggest an infectious factor in cardiac myxoma and certain histopathological features indicate herpes simplex virus type 1 (hsv-1) infection. we hypothesized that hsv-1 may be involved in the pathogenesis of cardiac myxoma. paraffin-embedded tissue samples from 17 patients with atrial myxoma were investigated for hsv-1 antigen by immunohistochemistry and viral genomic dna by nested polymerase chain reaction. the histogenesis and oncogenesis of atrial myxoma were assessed by the exp ...200314633612
evaluations of unformulated and formulated dendrimer-based microbicide candidates in mouse and guinea pig models of genital herpes.prevention of sexually transmitted infections is a priority in developed and developing countries. one approach to prevention is the use of topical microbicides, and one promising approach is the use of dendrimers, highly branched macromolecules synthesized from a polyfunctional core. three new dendrimer products developed to provide stable and cost-efficient microbicides were initially evaluated in vitro for anti-herpes simplex virus activity and then in vivo by using a mouse model of genital h ...200314638483

prenatal transfer of low amounts of herpes simplex virus (hsv)-specific antibody protects newborn mice against hsv infection during acute maternal stress.given their immunocompromised status, neonates rely heavily upon maternally derived, herpes simplex virus (hsv)-specific antibody for resistance to hsv infection. interestingly, previous studies have documented a decreased transfer of maternal igg antibody and immunocompetence of the offspring following perinatal exposure to stress-induced corticosterone. however, we recently demonstrated that the transplacental transfer of relatively high amounts of hsv-specific antibody is resilient to acute m ...200414651943
clinical signs as a guide for performing hsv-pcr in correct diagnosis of herpes simplex virus encephalitis.clinical criteria (symptoms) are not reliable enough to differentiate between different causes of encephalitis. the clinical presentation of herpes simplex virus encephalitis (hsve) is not classically constant and in such a patient, therefore, it is vital to make early diagnosis.200314652434
codon-optimized cloning, expression and characertization of the c-terminal region of human apoptotic protein gadd34 in escherichia coli.the human gadd34 (growth arrest and dna damage-inducible 34) is the product of an apoptosis- and dna-damage-inducible gene. the c-terminus domain of gadd34 is highly homologous to hsv-1 gamma-1 34.5, hsv-2 and the african swine fever virus virulence-associated factor nl-s. among these viral proteins, hsv-1 gamma 34.5 protein is known to prevent apoptosis of viral-infected cells. because of the difficulty in expressing gadd34 protein or any of its fragments, including the c-terminus (amino acids ...200414657671
