Sabah has the highest prevalence of β-thalassemia in Malaysia, with the Filipino β-deletion as the predominant mutation. Patients with the homozygous Filipino β-deletion exhibit phenotypic heterogeneity due to various genetic modifiers, yet the effects of these modifiers on the clinical phenotype remain poorly understood. This study investigated the effects of the coinheritance of α-thalassemia, I-γ rs7482144, rs766432, and 5'HS4 rs16912979 polymorphisms on the clinical phenotype of homozygous Filipino β-deletion patients in Sabah.

Background and objective Shoulder dislocations account for around half of all major joint dislocations in the UK and pose a significant healthcare burden. Management decisions post-reduction procedures involve a range of options, including conservative measures, surgery, and physiotherapy. Patient-reported outcome measures (PROMs), such as the Oxford Shoulder Instability Score (OSIS) and Simple Shoulder Test (SST), have emerged as crucial tools for evaluating treatment outcomes, reflecting a shift towards patient-centred care.

Article Synopsis
  • The study explores the implementation of a digital health intervention (DHI) designed for supporting self-management among long COVID patients, involving a patient app and a clinician dashboard.
  • Using qualitative analysis and Normalisation Process Theory, researchers found that the DHI was adaptable to various healthcare settings, enhancing collaboration among healthcare professionals while acknowledging the necessity for in-person care.
  • The findings suggest that DHIs can potentially transform traditional healthcare engagement patterns, emphasizing the importance of organizational context and individual experiences in successful implementation.

Article Synopsis
  • Mentha arvensis, also known as peppermint, was studied for its toxic and repellent effects using essential oil (MaEO) on the cockroach Nauphoeta cinerea at various concentrations.
  • The study utilized gas chromatography-mass spectrometry (GC-MS) to identify major compounds in MaEO, revealing that menthol is the predominant component at 71.31%.
  • Results showed that MaEO decreased oxidative stress markers like lipid peroxidation and non-protein thiols, while key compounds indicated potential analgesic properties through molecular docking studies.

Type 2 Diabetes Mellitus (T2DM) presents a substantial health concern on a global scale, driving the search for innovative therapeutic strategies. Phytochemicals from medicinal plants, particularly Ocimum tenuiflorum (Holy Basil), have garnered attention for their potential in T2DM management. The increased focus on plant-based treatments stems from their perceived safety profile, lower risk of adverse effects, and the diverse range of bioactive molecules they offer, which can target multiple pathways involved in T2DM.

Pyridone heterocycles, such as furo[2,3-b]pyridines, have emerged as prominent scaffolds in medicinal chemistry due to their versatile pharmacological properties, including significant anticancer activity. In this study, we successfully synthesized new pyridine-2(H)-one, nicotinonitrile, and furo[2,3-b]pyridine derivatives from chalcones bearing 4-(benzyloxy)phenyl and dichlorothiophenyl subunits to explore their therapeutic potential against breast cancer. By employing a synthetic strategy involving Claisen-Schmidt condensation followed by sequential cyclizations and functional modifications, we synthesized and characterized four compounds (MI-S0, MI-S1, MI-S2, and MI-S3) using various spectroscopic methods, including FT-IR, H-NMR, C-NMR, DEPT, H,H- and C,H-COSY, and HRMS.

Empirical rovibrational energy levels are presented for the third most abundant, asymmetric carbon dioxide isotopologue, OCO, based on a compiled dataset of experimental rovibrational transitions collected from the literature. The 52 literature sources utilized provide 19,438 measured lines with unique assignments in the wavenumber range of 2-12,676 cm. The MARVEL (Measured Active Rotational-Vibrational Energy Levels) protocol, which is built upon the theory of spectroscopic networks, validates the great majority of these transitions and outputs 8786 empirical rovibrational energy levels with an uncertainty estimation based on the experimental uncertainties of the transitions.

Manufacturing a highly effective sorbent for removing UO ions from aqueous effluents is vital for safeguarding the environment and recovering valuable resources. This research presents an innovative strategy employing adsorbents derived from pullulan, specifically tailored with furfuryl-amidoxime (FAO), to improve their affinity for UO ions. The formation of a UO ion-imprinted sorbent (U-II-P) was achieved by crosslinking the UO/FAO-modified pullulan (FAO-P) complex with bis(maleimido)ethane (BME) via click Diels-Alder (DA) cyclization, enhancing its attraction and specificity for UO ions.

Chemical and electrochemical Li-ion insertion in transition metal oxides, either a phase transformation reaction (ions insert into specific crystallographic sites of the host lattice) or a solid solution insertion (ions distribute uniformly throughout the host lattice), enables high energy density electrochemical energy storage. Many phase transformation cathode materials, that undergo two-phase reactions, exhibit high theoretical capacities arising from multi-electron redox reactions. However, challenges in distortive phase transformations and uncontrolled phase nucleation, propagation, segregation, and co-existence continue to limit the energy density, (dis)charging rate performances, and cycling stability of available phase transformation cathode materials.

Droughts have become more severe and frequent due to global warming. In this context, it is widely accepted that for drought assessments, both water supply (rainfall) and demand (standardized precipitation evapotranspiration index, SPEI) should be considered. Using SPEI, we explored the spatial-temporal patterns of dry and wet annual and seasonal changes in five sub-regions of East Asia during 1902-2018.

Abiotic stresses including sodium chloride (NaCl) are known to negatively affect plant physiology and seed germination by inducing a delay in establishing seedling emergence. The monoterpene carvacrol is the major component of several aromatic plants and seems to interfere with germination and seedling growth. In this study, we investigated whether treatment with carvacrol attenuates the effects of NaCl on the germination and development of Allium cepa, where biochemical parameters were also analyzed.
