Physiologic Expression of the Candida albicans Pescadillo Homolog Is Required for Virulence in a Murine Model of Hematogenously Disseminated Candidia…

2012

ABSTRACT Morphogenetic conversions contribute to the pathogenesis of Candida albicans invasive infections. Many studies to date have convincingly demonstrated a link between filamentation and virulence; however, relatively little is known regarding the role of the filament-to-yeast transition during the pathogenesis of invasive candidiasis. We previously identified the C. albicans pescadillo homolog ( PES1 ) as essential during yeast growth and growth of lateral yeast on hyphae but not during hyphal growth. Furthermore, we demonstrated that PES1 is required for virulence in vivo in a Galleria mellonella larva model of candidiasis. Here, we have used a regulatable tetO-PES1 / pes1 strain to …

Data management and concurrency control in broadcast based asymmetric environments

2006

Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad Tens of millions of users have personal handheld devices with several network interfaces built-in, and the number of users and of network interfaces included are only increasing. This growth suggests a need for new methods to disseminate data to multiple clients, and cyclic broadcast is one approach. We do a survey on the various data management protocols that describe how to broadcast the data, and the concurrency control protocols that make sure all access to the database is consistent. The various data management and concurrency control techniques deals with the restrictions in asymmetric broadcas…

Universidad Politécnica Radiotelevisión. Creación y primera etapa (2000-2008)

2012

En el artículo se trata la historia de los canales UPVRadio y Universidad Politécnica Televisión desde el año 2000 a 2008, incluyendo el proceso de estudio, diseño y puesta en marcha de ambos y una descripción de los objetivos, el modelo de gestión, la plantilla, los canales de emisión, la programación, la audiencia y las fuentes de financiación alternativa en el régimen permanente. Se comenta también la infraestructura de soporte de ambos canales, con apartados para las dependencias de la cadena, el equipamiento de la radio y el de la televisión.

Idrosemina Naturalistica

2016

Le applicazioni di idrosemina generalmente tendono a ricostituire un adeguato livello di copertura vegetale, per migliorare l’efficacia contro fenomeni erosivi e di instabilità dei versanti, ma spesso trascurano l’aspetto naturalistico. Si utilizzano cioè miscele di specie erbacee che spesso pongono scarsa attenzione all’ecologia del sito di intervento. All’approccio tecnico occorre quindi affiancare quello naturalistico, che, dal contesto vegetazionale, scarti le specie alloctone e condizioni la scelta delle specie erbacee da utilizzare. Il caso studio della discarica di Termini Imerese (Palermo), prevedeva un ricoprimento vegetale di 7,4 ha mediante idrosemina direttamente sul terreno di …

Probable disseminated Mycobacterium abscessus subspecies bolletii infection in a patient with idiopathic CD4+ T lymphocytopenia: a case report.

2012

Abstract Introduction Rapidly growing mycobacteria are opportunistic pathogens in patients with underlying risk factors. Mycobacterium abscessus subsp. bolletii is a newly recognized member of rapidly growing mycobacteria, isolated from respiratory tract and cutaneous infections. Case presentation We describe a case of chronic disseminated infection caused by M. abscessus subsp. bolletii in a 38-year-old Sri Lankan man with idiopathic CD4+ T lymphocytopenia. Idiopathic CD4+ T lymphocytopenia is a rare cause of immunodysfunction that, similar to human immunodeficiency virus infection, causes a depletion of CD4+ T lymphocytes. M. abscessus subsp. bolletii infection was diagnosed by culture is…

SARS-CoV-2 in patients with cancer: possible role of mimicry of human molecules by viral proteins and the resulting anti-cancer immunity

2021

AbstractA few reports suggest that molecular mimicry can have a role in determining the more severe and deadly forms of COVID-19, inducing endothelial damage, disseminated intravascular coagulation, and multiorgan failure. Heat shock proteins/molecular chaperones can be involved in these molecular mimicry phenomena. However, tumor cells can display on their surface heat shock proteins/molecular chaperones that are mimicked by SARS-CoV-2 molecules (including the Spike protein), similarly to what happens in other bacterial or viral infections. Since molecular mimicry between SARS-CoV-2 and tumoral proteins can elicit an immune reaction in which antibodies or cytotoxic cells produced against t…

Successful gamete intrafallopian transfer following failed artificial insemination by donor: evidence for a defect in gamete transport?

1988

Gamete intrafallopian transfer (GIFT) was offered as an alternative treatment to 48 women who failed to conceive after artificial insemination with donor semen (AID) in numerous attempts (9 to 24 cycles). The evaluation of these women showed no major cause of infertility as evidenced by normal endocrine, cervical, uterine, and tubal factor studies. Their partners were either azoospermic or severely oligoasthenospermic. During the GIFT cycle, follicular development was induced with (1) clomiphene citrate (days 3 to 7) plus human menopausal gonadotropins (hMG) from day 6 on or (2) human follicle-stimulating hormone (days 3 to 4) plus hMG (day 5 on), until ultrasound revealed 2 follicles 16 mm…

Sperm cryopreservation in oncological patients: a 14-year follow-up study.

2006

Objective Oncologic treatments can destroy spermatogenic dividing cells and cause azoospermia which could be irreversible. Sperm banking is the best option to preserve male fertility after these treatments. It is easy, inexpensive, and safe. To date, few clinical data are available about large series of cancer patients. Our objective was to determine the usefulness of these preventive sperm freezing protocols. Design Prospective study. Setting University-affiliated private fertility center. Patient(s) One hundred eighty-six cancer patients who banked sperm samples at our center before surgery or chemo- or radiotherapy treatments from 1991 to 2004. Intervention(s) Conjugal status, age, type …

Deficiencies in reporting results of lesbians and gays after donor intrauterine insemination and assisted reproductive technology treatments: a revie…

2015

At a time when increasing numbers of lesbians and gays consider parenthood using reproductive assistance in infertility centers, the present review aims to summarize the results obtained so far by lesbians after intrauterine insemination (IUI) and in-vitro fertilization (IVF) using donor spermatozoa (D-IUI and D-IVF, respectively) and gays entering into gestational-surrogacy programs. Data show that gays display normal semen parameters and lesbians exhibit no specific causes of female infertility except perhaps for polycystic ovary syndrome (PCOS) and some PCOS-related factors. Pair-bonded lesbians entering into D-IUI programs, tend to have higher pregnancy and delivery percentages followin…
