The nuclear localization signal of CPSF6 governs post-nuclear import steps of HIV-1 infection.

The early stages of HIV-1 infection include the trafficking of the viral core into the nucleus of infected cells. However, much remains to be understood about how HIV-1 accomplishes nuclear import and the consequences of the import pathways utilized on nuclear events. The host factor cleavage and polyadenylation specificity factor 6 (CPSF6) assists HIV-1 nuclear localization and post-entry integration targeting.

Total Hip Arthroplasty for Avascular Necrosis in a Patient With Hemophilia B.

Avascular necrosis (AVN) of the femoral head accounts for up to 10% of all total hip arthroplasties performed annually. Typically associated with intravascular coagulation, AVN is extremely rare in patients with bleeding disorders such as hemophilia B. In this report, we describe the therapeutic management of a 46-year-old male with hemophilia B, presenting with chronic left hip pain and AVN of the femoral head.

Complete elbow ankylosis secondary to heterotopic ossification: operative management leads to fair to excellent long-term outcomes.

Background: Heterotopic ossification in the elbow, often caused by trauma or neurogenic factors, can lead to limited range of motion and physical impairment, while severe cases may result in debilitating loss of function. Complete bony ankylosis of the elbow, though rare, presents challenges in treatment due to complex anatomy and high recurrence rates, with limited literature on management and outcomes. This study retrospectively investigates cases of elbow ankylosis secondary to heterotopic ossification, assessing long-term functional outcomes following operative intervention and standardized rehabilitation.

Spontaneous Anthropocentric Language Use in University Students' Explanations of Biological Concepts Varies by Topic and Predicts Misconception Agreement.

Previous research has shown that students employ intuitive thinking when understanding scientific concepts. Three types of intuitive thinking-essentialist, teleological, and anthropic thinking-are used in biology learning and can lead to misconceptions. However, it is unknown how commonly these types of intuitive thinking, or cognitive construals, are used spontaneously in students' explanations across biological concepts and whether this usage is related to endorsement of construal-consistent misconceptions.

MircoRNAs predict and modulate responses to chemotherapy in leukemic patients.

Leukemia covers a broad category of cancer malignancies that specifically affect bone marrow and blood cells. While different kinds of leukemia have been identified, effective treatments are still lacking for most forms, and even those treatments considered effective can lead to relapses. MicroRNAs, or miRNAs, are short endogenous non-coding single-stranded RNAs that help control the epigenetics of gene expression.

A fatal case of disseminated infection in a renal transplant recipient.

Dematiaceous molds often cause noninvasive disease but have the potential to cause disseminated infection, particularly in immunosuppressed hosts. is the most neurotropic of dematiaceous molds and is associated with brain abscesses, but disseminated infection is quite rare. Here we present a case of disseminated in a 67-year-old renal transplant recipient with multifocal soft tissue, bone and presumed central nervous system involvement.

Predictive equation derived from 6,497 doubly labelled water measurements enables the detection of erroneous self-reported energy intake.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

Microtubule acetylation is not required for HIV-1 infection or TRIM69-mediated restriction of HIV-1 infection.

Unlabelled: Microtubule acetylation, a post-translational modification catalyzing the addition of acetyl groups to lysine residues on alpha tubulin, confers mechanical resilience to microtubules and influences intracellular cargo transport. Despite its known cellular functions, its role in viral infections remains poorly understood. The goal of this study was to determine the role of microtubule acetylation in both HIV-1 infection and TRIM69-mediated restriction.
