Self-healing and hyperelastic magneto-iono-elastomers through molecular confinement of magnetic anions.

Magneto-responsiveness in living organisms, exemplified by migratory birds navigating vast distances, offers inspiration for soft robots and human-computer interfaces. However, achieving both high magneto-responsiveness and resilient mechanical properties in synthetic materials has been challenging. Here, we develop magneto-iono-elastomers (MINEs), combining exceptional magnetization [2.

Management of perioperative thyrotoxicosis - what to do when standard therapy is contraindicated or fails?

Background: Current guidelines recommend that hyperthyroid patients should be rendered euthyroid prior to surgical procedures. These guidelines rely heavily on the use of ATDs as the primary medication, and do not give recommendations for patients who have contraindications to ATDs, or for whom standalone ATD treatment is inadequate.

Objectives: To evaluate the efficacy and safety of adjunctive pharmacological therapy and/or therapeutic plasma exchange (TPE) in the perioperative management of patients with thyrotoxicosis who were intolerant to ATD or for whom standalone ATD therapy was inadequate to achieve euthyroidism prior to surgery.

A Rare Case of Functional Metastatic Follicular Thyroid Carcinoma With Concomitant Thyrotoxicosis.

We report a case of a 60-year-old lady with metastatic follicular thyroid carcinoma (FTC) who was presented with thyrotoxicosis and heart failure symptoms after total thyroidectomy. Clinical features and investigations led to the diagnosis of functional metastatic FTC with concomitant thyrotoxicosis. Levothyroxine therapy was stopped, and she was treated with propylthiouracil (PTU) followed by serial radioiodine treatments (RAITs) with good control of thyrotoxicosis and metastases.

Protonation State of a Bioactive Compound Regulates Its Release from Lamellar Gel-Phase Bilayers.

Lamellar gel networks (LGNs) in personal care or pharmaceutical lotions and creams provide an opaque cream appearance and a creamy texture to these products. Within the LGNs, the lamellar gel (L) phase composed of regularly spaced bilayers of surfactants and long-chain fatty alcohols is predominately responsible for the unique rheological properties of the LGNs. To extend the shelf life of LGN-containing products, bioactive compounds with antimicrobial properties are often incorporated into the formulation.

Molecular dynamics simulations reliably identify vibrational modes in far-IR spectra of phospholipids.

The properties of self-assembled phospholipid membranes are of essential importance in biochemistry and physical chemistry, providing a platform for many cellular life functions. Far-infrared (far-IR) vibrational spectroscopy, on the other hand, is a highly information-rich method to characterize intermolecular interactions and collective behaviour of lipids that can help explain, , chain packing, thermodynamic phase behaviour, and sequestration. However, reliable interpretation of the far-IR spectra is still lacking.

Whole genome and transcriptome integrated analyses guide clinical care of pediatric poor prognosis cancers.

The role for routine whole genome and transcriptome analysis (WGTA) for poor prognosis pediatric cancers remains undetermined. Here, we characterize somatic mutations, structural rearrangements, copy number variants, gene expression, immuno-profiles and germline cancer predisposition variants in children and adolescents with relapsed, refractory or poor prognosis malignancies who underwent somatic WGTA and matched germline sequencing. Seventy-nine participants with a median age at enrollment of 8.

Rebalancing of the skin microbiome with an emollient 'plus' for effective management of atopic dermatitis: A mini review.

A balanced and diverse skin microbiome is pivotal for healthy skin. Dysregulation of the skin microbiome could disrupt the skin barrier function and result in the development of atopic dermatitis (AD), a common chronic and relapsing inflammatory skin disorder. Given the role that the skin microbiome plays in the initiation and maintenance of AD, maintaining a healthy skin microbiome is crucial for effective disease management.

Instrument-Tissue Interaction Detection Framework for Surgical Video Understanding.

Instrument-tissue interaction detection task, which helps understand surgical activities, is vital for constructing computer-assisted surgery systems but with many challenges. Firstly, most models represent instrument-tissue interaction in a coarse-grained way which only focuses on classification and lacks the ability to automatically detect instruments and tissues. Secondly, existing works do not fully consider relations between intra- and inter-frame of instruments and tissues.

The roles of ceramides and multivesicular emulsion (MVE) technology in atopic dermatitis: a narrative review.

Introduction: Atopic dermatitis (AD) is a highly prevalent chronic inflammatory skin condition. In Malaysia, a prevalence of 13.4% was reported for children between one and six years of age, one of the highest prevalence rates of AD in Asia.

Self-Healable and 4D Printable Hydrogel for Stretchable Electronics.

Materials with high stretchability and conductivity are used to fabricate stretchable electronics. Self-healing capability and four-dimensional (4D) printability are becoming increasingly important for these materials to facilitate their recovery from damage and endow them with stimuli-response properties. However, it remains challenging to design a single material that combines these four strengths.

The oral health landscape in Singapore: A commentary on key features, challenges and future policies.

Over the last decade, Singapore has grappled with substantial healthcare challenges, chiefly a bourgeoning aging population and a mounting burden of chronic diseases. The oral health landscape has also changed, with the Ministry of Health placing a greater focus on a life-course approach supported by policies that facilitate Singaporeans to receive dental care appropriately and affordably. A pivotal oral health policy is the National Dental Strategy, a comprehensive framework governing dental services in the public sector.

Hydrophobic Matching Dictates over the Linear Rule of Mixtures in Binary Lipid Membranes.

Biological membranes feature heterogeneous mixtures of lipids with different head and tail characteristics. Their biophysical properties are dictated by the intimate interaction among different constituent lipids. Previous studies suggest that the membrane area-per-lipid (APL) deviates from the linear rule of mixtures (LRM) for binary lipid membranes, but the underlying mechanism remains elusive.

Oral enzyme therapy for maple syrup urine disease (MSUD) suppresses plasma leucine levels in intermediate MSUD mice and healthy nonhuman primates.

Maple syrup urine disease (MSUD) is an inborn error of branched-chain amino acid metabolism affecting several thousand individuals worldwide. MSUD patients have elevated levels of plasma leucine and its metabolic product α-ketoisocaproate (KIC), which can lead to severe neurotoxicity, coma, and death. Patients must maintain a strict diet of protein restriction and medical formula, and periods of noncompliance or illness can lead to acute metabolic decompensation or cumulative neurological impairment.

Risk factors for disease severity among children with Covid-19: a clinical prediction model.

Background: Children account for a significant proportion of COVID-19 hospitalizations, but data on the predictors of disease severity in children are limited. We aimed to identify risk factors associated with moderate/severe COVID-19 and develop a nomogram for predicting children with moderate/severe COVID-19.

Methods: We identified children ≤ 12 years old hospitalized for COVID-19 across five hospitals in Negeri Sembilan, Malaysia, from 1 January 2021 to 31 December 2021 from the state's pediatric COVID-19 case registration system.

Optimizing human α-galactosidase for treatment of Fabry disease.

Fabry disease is caused by a deficiency of α-galactosidase A (GLA) leading to the lysosomal accumulation of globotriaosylceramide (Gb3) and other glycosphingolipids. Fabry patients experience significant damage to the heart, kidney, and blood vessels that can be fatal. Here we apply directed evolution to generate more stable GLA variants as potential next generation treatments for Fabry disease.

The SARS-Cov-2 (COVID-19) vaccination began in Malaysia in March 2021 among frontliners and healthcare workers. Everyone at our hospital received the tozinameran (BNT162b2) Messenger RNA COVID-19 vaccine. Although hypertension has not been mentioned explicitly as an adverse event, concerns were raised after some healthcare staff observed an increase in their blood pressures.

Modulation of lipid vesicle-membrane interactions by cholesterol.

Nanoscale lipid vesicles are attractive vehicles for drug delivery. Although often considered as soft nanoparticles in terms of mechanical deformability, the fluidic nature of the lipid membrane makes their interactions with another lipid membrane much more complex. Cholesterol is a key molecule that not only effectively stiffens lipid bilayer membranes but also induces membrane fusion.
