Diterpene chemical space of Aeollanthus buchnerianus Briq. aerial part.

The Plectranthinae clade, which includes genera such as Plectranthus, Ocimum, and Aeollanthus, is well known for its diverse array of diterpenoids. While numerous studies have deepened the understanding of diterpene diversity across the clade, Aeollanthus species remain underexplored, with only two studies focusing on their diterpene profiles. The NMR-based chemical profiling of the EtOAc leaf extract of the rocky and succulent species Aeollanthus buchnerianus Briq.

Anti-VEGF drugs compared with laser photocoagulation for the treatment of diabetic retinopathy: a systematic review and meta-analysis.

Background: Diabetic retinopathy is a major cause of sight loss in people with diabetes. The most severe form, proliferative diabetic retinopathy, carries a high risk of vision loss, vitreous haemorrhage, macular oedema and other harms. Panretinal photocoagulation is the primary treatment for proliferative diabetic retinopathy.

Inverse linear association between blood haemoglobin and oxygen saturation accuracy measured by pulse oximetry: a cross-sectional analysis in individuals with COVID-19 infection.

Background: Pulse oximetry measures oxygen saturation non-invasively by using differential absorption of infrared signals which are dependent on the oxyhaemoglobin:deoxyhaemoglobin ratio. We tested the hypothesis that pulse oximetry error in measurements of blood oxygen saturations may be associated with blood haemoglobin levels.

Methods: The study design was an observational study of all adult patients admitted to a large teaching hospital with suspected or confirmed COVID-19 infection from February 2020 to December 2021 who had arterial blood gases (ABG) drawn.

Lysis of human erythrocytes due to Piezo1-dependent cytosolic calcium overload as a mechanism of circulatory removal.

Hematopoietic stem cells surrender organelles during differentiation, leaving mature red blood cells (RBC) devoid of transcriptional machinery and mitochondria. The resultant absence of cellular repair capacity limits RBC circulatory longevity, and old cells are removed from circulation. The specific age-dependent alterations required for this apparently targeted removal of RBC, however, remain elusive.

Will blood-informed design signal the fourth generation of cardiac assist devices?

Mechanical circulatory support devices have profoundly transformed the management of severe cardiothoracic disorders. While heart transplantation is the gold standard therapy for end-stage heart disease, long-term mechanical support devices are a viable alternative for those ineligible and/or those awaiting organ availability. Major technological advancements were made over first 5 decades of development, resulting in improved durability and survival with reduced adverse events.

An enhanced and rapid method for von Willebrand factor multimer analysis for mechanical circulatory device testing.

Background: Von Willebrand factor (VWF) is a critical glycoprotein in hemostasis and is an important factor in diagnosing bleeding disorders. Albeit the analysis of VWF is often compromised by inconsistent methodologies and challenges quantifying multimeric size. Current VWF multimer analysis methods are costly, time-consuming, and often inconsistent; thus, demanding skilled professionals.

Devices for remote continuous monitoring of people with Parkinson's disease: a systematic review and cost-effectiveness analysis.

Background: Parkinson's disease is a brain condition causing a progressive loss of co ordination and movement problems. Around 145,500 people have Parkinson's disease in the United Kingdom. Levodopa is the most prescribed treatment for managing motor symptoms in the early stages.

Penetration of oils into hair.

Objective: The objective of this work was to understand how triglyceride plant oils can deliver strength and softness benefits to hair by their penetration. These plant oils are complex mixtures of TAGs, so the initial studies performed were with pure TAGs and then these data compared to plant oils and their measured TAG compositions.

Methods: LC-MS was used to identify the di and triglycerides in coconut oil, Camellia oleifera oil and safflower seed oil.

A requirement for the use of supplementary oxygen to guide medical treatment decisions may introduce bias against non-white individuals.

Anti-Vascular Endothelial Growth Factor Drugs Compared With Panretinal Photocoagulation for the Treatment of Proliferative Diabetic Retinopathy: A Cost-Effectiveness Analysis.

Objectives: This study aimed to evaluate the cost-effectiveness of anti-vascular endothelial growth factor drugs (anti-VEGFs) compared with panretinal photocoagulation (PRP) for treating proliferative diabetic retinopathy (PDR) in the United Kingdom.

Methods: A discrete event simulation model was developed, informed by individual participant data meta-analysis. The model captures treatment effects on best corrected visual acuity in both eyes, and the occurrence of diabetic macular edema and vitreous hemorrhage.

Expert assessment of the impact of ship-strikes on cetacean welfare using the Welfare Assessment Tool for Wild Cetaceans.

Human activities are increasingly impacting our oceans and the focus tends to be on their environmental impacts, rather than consequences for animal welfare. Global shipping density has quadrupled since 1992. Unsurprisingly, increased levels of vessel collisions with cetaceans have followed this global expansion of shipping.

Ablative and non-surgical therapies for early and very early hepatocellular carcinoma: a systematic review and network meta-analysis.

Background: A wide range of ablative and non-surgical therapies are available for treating small hepatocellular carcinoma in patients with very early or early-stage disease and preserved liver function.

Objective: To review and compare the effectiveness of all current ablative and non-surgical therapies for patients with small hepatocellular carcinoma (≤ 3 cm).

Design: Systematic review and network meta-analysis.

The effectiveness of ablative and non-surgical therapies for early hepatocellular carcinoma: Systematic review and network meta-analysis of randomised controlled trials.

Background & Aims: Non-surgical therapies are frequently used for patients with early or very early hepatocellular carcinoma (HCC). The aim of this systematic review and network meta-analysis (NMA) was to evaluate and compare the effectiveness of ablative and non-surgical therapies for patients with small HCC.

Methods: Nine databases were searched (March 2021) along with clinical trial registries.

A Bio-Inspired Arched Foot with Individual Toe Joints and Plantar Fascia.

This paper presents the design and testing of an arched foot with several biomimetic features, including five individual MTP (toe) joints, four individual midfoot joints, and plantar fascia. The creation of a triple-arched foot represents a step further in bio-inspired design compared to other published designs. The arched structure creates flexibility that is similar to human feet with a vertical deflection of up to 12 mm.

Mining the chemical diversity of the hemp seed ( L.) metabolome: discovery of a new molecular family widely distributed across hemp.

Hemp ( L.) is a widely researched industrial crop with a variety of applications in the pharmaceutical, nutraceutical, food, cosmetic, textile, and materials industries. Although many of these applications are related to its chemical composition, the chemical diversity of the hemp metabolome has not been explored in detail and new metabolites with unknown properties are likely to be discovered.
