Palladium-Catalyzed Alkoxycarbonylation of Alcohols for the Synthesis of Cyclobutanecarboxylates with α-Quaternary Carbon Centers.

A palladium-catalyzed alkoxycarbonylation with two different alcohols for the synthesis of cyclobutanecarboxylates bearing an α-quaternary carbon center is presented. The reaction utilizes readily accessible starting materials, tolerates a broad scope of functional groups, and provides a straightforward and efficient approach for the synthesis of a diverse array of cyclobutanecarboxylates bearing an α-quaternary carbon. Meanwhile, this strategy effectively prevents the transition-metal-catalyzed ring-opening of cyclobutanols, preserves the cyclobutane framework, and affords 1,1-disubstituted cyclobutanecarboxylates in high yields with excellent regioisomeric ratios.

Peripheral neuropathy: from guidelines to clinical practise.

Purpose Of Review: Chemotherapy-induced peripheral neuropathy (CIPN) is a substantial adverse effect of anticancer therapy. No effective preventive strategies are established in clinical routine, although some forms of cryotherapy or compression therapy seem to be promising. CIPN is difficult to grade objectively and has mostly relied on a clinician- or patient-based rating that is subjective and not easily reproducible.

Strength of Genetic Associations with Thyrotropin Values Differs Between Populations with Similarity to African and European Reference Populations.

Epidemiological data suggest the population distribution of thyrotropin (TSH) values is shifted toward lower values in self-identified Black non-Hispanic individuals compared with self-identified White non-Hispanic individuals. It is unknown whether genetic differences between individuals with genetic similarities to African reference populations (GSA) and those with similarities to European reference populations (GSE) contribute to these observed differences. We aimed to compare genome-wide associations with TSH and putative causal TSH-associated variants between GSA and GSE groups.

Herbicide glyphosate efficiently inhibits growth of pathogenic algae species, suggesting the presence of novel pathways for the development of anti-algal drugs.

are ubiquitous algae and occasional pathogens of humans and animals. While rare, the infection is often fatal and treatment options are limited to antifungals with low efficiency. Here, using growth curve assays, we demonstrate that five pathogenic species of () were fully inhibited by 50-100 μg/mL of herbicide glyphosate, suggesting novel pathways that can be considered for anti-algal drug development.

Operationalising a Haemophilia Gene Editing Lexicon for Practical Use.

Introduction: Gene editing therapies offer the possibility of substantial improvement in treatment and quality of life for people with haemophilia (PWH) in a landscape of dynamic therapeutic advancement. Developing a common and understandable language to discuss gene editing will be essential to ensure these treatments can be deployed in a safe and effective manner with fully informed and shared decision-making between healthcare professionals (HCPs) and PWH. A lexicon explaining and clarifying key concepts is one potential tool to address these aims.

Occurrence and clinical correlates of SARS-CoV-2 viremia in two German patient cohorts.

Viremia defined as detectable SARS-CoV-2 RNA in the blood is a potential marker of disease severity and prognosis in COVID-19 patients. Here, we determined the frequency of viremia in serum of two independent COVID-19 patient cohorts within the German National Pandemic Cohort Network (German: tionales andemie horten etzwerk, NAPKON) with diagnostic RT-PCR against SARS-CoV-2. A cross-sectional cohort with 1,122 COVID-19 patients (German: , SUEP) and 299 patients recruited in a high-resolution platform with patients at high risk to develop severe courses (German: , HAP) were tested for viremia.

Recovery and Degradation Drive Changes in the Dispersal Capacity of Stream Macroinvertebrate Communities.

Freshwater ecosystems face significant threats, including pollution, habitat loss, invasive species, and climate change. To address these challenges, management strategies and restoration efforts have been broadly implemented. Across Europe, such efforts have resulted in overall improvements in freshwater biodiversity, but recovery has stalled or failed to occur in many localities, which may be partly caused by the limited dispersal capacity of many species.

Navigating Dementia and Delirium: Balancing Identity and Interests in Advance Directives.

The moral authority of advance directives (ADs) in the context of persons living with dementia (PLWD) has sparked a multifaceted debate, encompassing concerns such as authenticity and the appropriate involvement of caregivers. Dresser critiques ADs based on Parfit's account of numeric personal identity, using the often-discussed case of a PLWD called Margo. She claims that dementia leads to a new manifestation of Margo emerging, which then contracts pneumonia.
