OBJECTIVE This study focuses on variation in brain morphology associated with supernumerary X chromosome and Klinefelter syndrome (KS). Using an unselected birth cohort of KS subjects and high-resolution MRI, the authors investigated the neuroanatomic consequences of the 47,XXY karyotype in the presence and absence of exogenous testosterone supplementation. METHODS Regional brain volumes were...
INTRODUCTION To evaluate the impact of needle driver design on laparoscopic suturing skills by experts and novices. METHODS Three experienced laparoscopic surgeons and 3 novice junior residents were asked to perform a fixed set of suturing tasks in a laparoscopic pelvic-trainer. The laparoscopic needle drivers compared were (1) the Ethicon driver (E 705R), (2) Karl Storz (KS) pistol grip (261...
AIDS-associated Kaposi's sarcoma (AIDS-KS) caused by human herpes virus 8 (HHV-8) is the most severe and resistant form of KS tumor. Our aim was to verify whether there is an association between HHV-8 variability and development of AIDS-KS in Brazil by comparing the HHV-8 variability between individuals without and with KS. Saliva samples and blood, when available, were analyzed by polymerase c...
Potassium sorbate (KS), a common food preservative, was evaluated to control postharvest decay of citrus fruit. Significant advantages of KS ver the commonly used sodium bicarbonate, which similarly improved fungicide performance, are the relatively low salt concentration of KS, the bsence of sodium, and its lower pH, so disposal of used KS solutions would raise fewer regulatory issues. The inf...
Kaposi's sarcoma-associated herpesvirus (KSHV) is the causal agent of all forms of Kaposi's sarcoma (KS), including AIDS-KS, endemic KS, classic KS and iatrogenic KS. Based on Open reading frame (ORF) K1 sequence analysis, KSHV has been classified into seven major molecular subtypes (A, B, C, D, E, F and Z). The distribution of KSHV strains varies according to geography and ethnicity. Xinjiang ...
BACKGROUND HIV-1 is known to play a critical role in the pathogenesis of AIDS-associated Kaposi's sarcoma (KS). However, it remains controversial whether KS cells are target cells for HIV infection. The aim of this study was to investigate the expression of chemokine receptors in KS cell cultures and to determine whether these cells can be infected by HIV-1. MATERIAL AND METHODS KS-derived ce...
The aims of the present study were to determine the prevalence of human herpesvirus type 8 (HHV-8) in HIV-positive Brazilian patients with (HIV+/KS+) and without Kaposi's sarcoma (HIV+/KS-) using PCR and immunofluorescence assays, to assess its association with KS disease, to evaluate the performance of these tests in detecting HHV-8 infection, and to investigate the association between anti-HH...
The relationship between Kaposi sarcoma-associated herpesvirus (KSHV) viremia and KS disease was investigated in 500 subjects who received treatment in Harare, Zimbabwe. Subjects were grouped by results of human immunodeficiency virus (HIV) type 1 serological tests, KS diagnosis, and KS clinical stage. The plasma KSHV DNA concentration was associated with concomitant KS and HIV-1 infection (AID...
Kaposi sarcoma (KS) is an aggressive cancer caused by human herpesvirus-8, primarily seen in immunocompromised patients. As opposed to the well-described cutaneous manifestations and pulmonary complications of KS, hepatic KS is rarely reported before death as most patients with hepatic KS do not manifest symptoms or evidence of liver injury. In patients with acquired immune deficiency syndrome,...
Thermococcus zilligii, a thermophilic anaerobe in freshwater, is useful for physiological research and biotechnological applications. Here we report the high-quality draft genome sequence of T. zilligii AN1(T). The genome contains a number of genes for an immune system and adaptation to a microbial biomass-rich environment as well as hydrogenase genes.
