Typical 22q11.2 deletion syndrome appears to confer a reduced risk of schwannoma.

Purpose: The LZTR1 gene has been associated with schwannomatosis tumor predisposition and is located in a region that is deleted in the great majority (89%) of patients with 22q11.2 deletion syndrome (22q11.2DS).

The role of CD32 during HIV-1 infection.

Persistence of latent HIV-1 in long-lived resting memory CD4+ T cells is a major barrier to curing HIV-1 infection, and thus a biomarker for latently infected cells would be of great scientific and clinical importance. Through an elegant discovery-based approach, Descours . reported that CD32a, an Fcγ receptor not normally expressed on T cells, is a potential biomarker for latently infected cells.

Innumerable Condyloma Acuminatum Tumors of the Bladder.

Condylomata acuminata caused by human papillomavirus (HPV), a sexually transmitted virus, are rarely seen beyond the external genitalia and anal region. Here, a patient with innumerable condyloma acuminatum of the bladder is presented. Attempted surgical resection was performed and intraoperative photographs are presented.

Defective proviruses rapidly accumulate during acute HIV-1 infection.

Although antiretroviral therapy (ART) suppresses viral replication to clinically undetectable levels, human immunodeficiency virus type 1 (HIV-1) persists in CD4(+) T cells in a latent form that is not targeted by the immune system or by ART. This latent reservoir is a major barrier to curing individuals of HIV-1 infection. Many individuals initiate ART during chronic infection, and in this setting, most proviruses are defective.

The Latent Reservoir for HIV-1: How Immunologic Memory and Clonal Expansion Contribute to HIV-1 Persistence.

Combination antiretroviral therapy (ART) for HIV-1 infection reduces plasma virus levels to below the limit of detection of clinical assays. However, even with prolonged suppression of viral replication with ART, viremia rebounds rapidly after treatment interruption. Thus, ART is not curative.

Rhes, a striatal-selective protein implicated in Huntington disease, binds beclin-1 and activates autophagy.

The protein mutated in Huntington disease (HD), mutant huntingtin (mHtt), is expressed throughout the brain and body. However, the pathology of HD is characterized by early and dramatic destruction selectively of the striatum. We previously reported that the striatal-specific protein Rhes binds mHtt and enhances its cytotoxicity.

The role of potential agents in making spatial perspective taking social.

A striking relationship between visual spatial perspective taking (VSPT) and social skills has been demonstrated for perspective-taking tasks in which the target of the imagined or inferred perspective is a potential agent, suggesting that the presence of a potential agent may create a social context for the seemingly spatial task of imagining a novel visual perspective. In a series of studies, we set out to investigate how and when a target might be viewed as sufficiently agent-like to incur a social influence on VSPT performance. By varying the perceptual and conceptual features that defined the targets as potential agents, we find that even something as simple as suggesting animacy for a simple wooden block may be sufficient.

Should social savvy equal good spatial skills? The interaction of social skills with spatial perspective taking.

Real-world perspective-taking problems frequently involve interactions among individuals, suggesting a potential social element to this seemingly spatial problem. Previous studies have suggested that the agency of the target in a perspective-taking task might influence reasoning. This hypothesis is tested directly by manipulating whether one takes the perspective of a potential agent or an object.

The stigmatising implications of presenting schizophrenia as a genetic disease.

This study aimed to investigate the hypothesis that belief in a genetic aetiology of schizophrenia will increase the stigma associated with the disorder. Levels of five potentially stigmatising attitudes were compared in two groups of participants who had read a vignette describing an individual who has schizophrenia. In one group the disorder was explained as being caused by 'genetic' factors, and in the other by 'environmental' factors.
