A Simple and Efficient Stereoselective Synthesis of a 2,3-Difluorosialic acid-based influenza virus neuraminidase inhibitor.

3-Fluoroneuraminosyl fluorides are invaluable probes for studying the catalytic mechanism of sialidases (neuraminidases), and as sialidase inhibitors. Significantly, when a C-3 equatorial fluorine is installed on a C-4 functionalised N-acylneuraminic acid (Neu)-based template, the compounds are potent and selective inhibitors of both influenza and parainfluenza sialidases, and of virus replication. Typically, the reported syntheses of 3-fluoroneuraminosyl fluorides involve either an enzymatic or a chemical synthesis that have uncontrolled stereoselectivity in the introduction of fluorine at C-3 of Neu and consequently yield a mixture of C-3 ax and C-3 eq fluoro derivatives.

From skin to heart: The rare journey of pleomorphic dermal sarcoma metastasis.

Cardiac tumours can be classified as neoplastic or non-neoplastic, with secondary tumours being significantly more common than primary ones. Among secondary tumours, melanoma has the highest propensity for cardiac involvement. Pleomorphic dermal sarcoma (PDS) is a rare skin neoplasm, with an estimated metastatic risk of 10% to 20%.

Distinct population-wide differences in contaminants and blood parameters in foraging green sea turtles.

The rising diversity and concentration of contaminants have surpassed ecological thresholds, threatening marine ecosystems. The effects of pollutants on marine animals, particularly sea turtles, are receiving increased attention due to their role as indicators of human impacts. This study examined the health implications of contaminant exposure in three green turtle (Chelonia mydas) foraging sites in the southern Great Barrier Reef, Australia.

Repeat expansions in gene in refractory chronic cough.

Introduction: Refractory chronic cough (RCC), persisting despite addressing contributory diagnoses, is likely underpinned by neurally mediated cough hypersensitivity. disorders are genetic neurodegenerative conditions caused by biallelic repeat expansion sequences, commonly presenting with cough, followed by neurological features including cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS). The prevalence and identifying clinical characteristics of repeat-expansion disorders in patients with RCC are unknown.

The adaptor protein Miro1 modulates horizontal transfer of mitochondria in mouse melanoma models.

Recent research has shown that mtDNA-deficient cancer cells (ρ cells) acquire mitochondria from tumor stromal cells to restore respiration, facilitating tumor formation. We investigated the role of Miro1, an adaptor protein involved in movement of mitochondria along microtubules, in this phenomenon. Inducible Miro1 knockout (Miro1) mice markedly delayed tumor formation after grafting ρ cancer cells.

Repurposing Licensed Drugs with Activity Against Epstein-Barr Virus for Treatment of Multiple Sclerosis: A Systematic Approach.

Background: Epstein-Barr virus (EBV) is implicated as a necessary factor in the development of multiple sclerosis (MS) and may also be a driver of disease activity. Although it is not clear whether ongoing viral replication is the driver for MS pathology, MS researchers have considered the prospect of using drugs with potential efficacy against EBV in the treatment of MS. We have undertaken scientific and lived experience expert panel reviews to shortlist existing licensed therapies that could be used in later-stage clinical trials in MS.

Decisions about Medical Treatment and Care, the Legality Assumptions and Sovereign Power - Empowering Patients Out of the State of Bare Life?

The framing of patients making decisions about their medical treatment and care as traditional legal decisions, thresholds and formalities is a means to avoid legal liabilities through a rationalisation of decision-making, autonomy and choice. A credible account for the actual place of patients posits the sovereign power (founded in the works of Carl Schmitt and Giorgio Agamben) of the health care professional deciding the state of exception - a discrete legal space where the authority of health care professionals is both lawful and beyond the law. This reveals that dealing with broadly conceived consent issues with more law, more process and procedure but without addressing the inherent legality assumptions that empower health care professionals will always be flawed.

Sex-specific associations between feto-placental growth and maternal physical activity volume and sitting time: Findings from the Queensland Family Cohort study.

Introduction: Antenatal physical activity (PA) is associated with beneficial changes in placental growth and function; however, the effect of excessive sitting time is less clear. The aim of this study was to investigate whether feto-placental growth changes with maternal activity, and whether these associations differ in a sex-specific manner.

Methods: This study included women enrolled in the Queensland Family Cohort study who self-reported PA and sitting time at 24 or 36 weeks of gestation.
