Palm kernel meal (PKM) presents a challenge for non-ruminant livestock feeding due to its high fibre content predominantly in the form of mannan. Microbial fermentation offers a sustainable solution for fibre hydrolysis in lignocellulosic biomass. In this study, a Bacillus subtilis strain (F6), with high mannanase secretion capability, was isolated from the environment.

Interdisciplinary learning is essential for equipping future health professionals to tackle the complexities of contemporary public health. This mixed-methods study investigates the experiences and perspectives of undergraduate public health students in Singapore on interdisciplinary learning in higher education and employed a convergent parallel design by combining a cross-sectional survey with in-depth interviews. Quantitative data were used to assess the relationship between students' exposure to interdisciplinary learning and its perceived value, while qualitative analysis explored key themes related to facilitators and barriers.

Thermodynamic theory suggests that the obvious mechanical behavior caused by temperature and interlayer angle will affect the physical properties of materials, such as mechanical properties and transportation behavior, and it is different from the behavior in three-dimensional bulk materials. We observe an abnormal physical effect of bilayer graphene/hexagonal boron nitride (G/BN)-carbon nanotube (CNT) heterostructures, with a normalized out-of-plane deformation and normalized bond angle percentage to almost several times higher those of pristine G/BN heterostructures (without CNT) at 700-800 K. Our combined finite element theory and molecular dynamics simulations confirmed that the combination of CNT and interlayer angle diverted and bridged the propagating crack and provided a stable crack propagation path and crack tip opening displacement, resulting in the stress fields to be controlled around the CNT at high temperature.

Background: Intrahepatic and perihepatic abscess (IPHA) is a severe yet understudied complication that can occur after hepatectomy. This multicenter study aimed to elucidate the clinical features, risk factors, and outcomes of IPHA after hepatectomy for hepatocellular carcinoma (HCC), and to develop a novel prediction model for personalized risk assessment.
Methods: This was a multicenter cohort study of HCC patients who underwent curative-intent hepatectomy.

Host-parasite relationships drive the evolution of both parties. In microbe-phage dynamics, CRISPR functions as an adaptive defense mechanism, updating immunity via spacer acquisition. Here, we investigated these interactions within the human gut microbiome, uncovering low frequencies of spacer acquisition at an average rate of one spacer every ∼2.

Infection prevention and control (IPC) programs form the basis of minimizing spread of pathogens in the healthcare setting and beyond. The COVID-19 pandemic amplified the demand for IPC. However, the environmental impact of IPC practices has yet to be addressed and attempts to quantify its climate implications have been sparse.

Introduction: Aesthetic medicine has evolved towards minimally invasive procedures, with biostimulators like Poly-L-Lactic Acid (PLLA), Calcium Hydroxylapatite (CaHA), and Polycaprolactone (PCL) gaining attention for their role in collagen induction, improving skin texture, elasticity, and volume. Combining these agents with other treatments-such as botulinum toxin, dermal fillers, and energy-based devices (e.g.

Radiotherapy is an integral modality in treating human cancers, but radioresistance remains a clinical challenge due to the involvement of multiple intrinsic cellular and extrinsic tumour microenvironment factors that govern radiosensitivity. To study the intrinsic factors that are associated with cancer radioresistance, we established 4 radioresistant prostate (22Rv1 and DU145) and head and neck cancer (FaDu and HK1) models by irradiating their wild-type parentals to 90 Gy, mimicking the fractionated radiotherapy schema that is often using in the clinic, and performed whole exome and transcriptome sequencing of the radioresistant and wild-type models. Comparative genomic analyses detected the enrichment of mismatch repair mutational signatures (SBS6, 14, 15, 20) across all the cell lines and several non-synonymous single nucleotide variants involved in pro-survival pathways.

Up to 50% of patients with pulmonary embolism (PE) experience hemodynamic instability and approximately 70% of patients who die of PE experience an accelerated cascade of symptoms within the first hours of onset of symptoms, thus necessitating rapid evaluation and intervention. Venoarterial extracorporeal membrane oxygenation and other ventricular assist devices, depending on the hemodynamic derangements present, may be used to stabilize patients with massive PE refractory to initial therapies or with contraindications to other interventions. Given the abnormalities in both pulmonary circulation and gas exchange caused by massive PE, venoarterial extracorporeal membrane oxygenation may be considered the preferred form of mechanical circulatory support for most patients.

Background: The importance of nutritional status is underappreciated in patients with heart failure (HF). This study aimed to describe the range of the prognostic nutrition index (PNI), and the clinical characteristics and outcomes according to PNI, in patients with HF with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF). The primary outcome was the composite of HF hospitalization or cardiovascular death.

Mesenchymal Stromal/Stem Cells (MSCs) are among the most frequently studied cell types in clinical trials, and their small extracellular vesicles (sEVs) are now being extensively investigated for therapeutic applications. The RNA cargo of MSC-sEVs, particularly miRNAs and mRNAs, is widely believed to be a key therapeutic component of these vesicles. In this review, we critically examine using first principles and peer-reviewed literature, whether MSC- extracellular vesicles (MSC-EVs) can deliver sufficient quantity of functional miRNA or mRNA to target compartments within recipient cells to elicit a pharmacological response.

We present the implementation of the time-domain multichromophoric fluorescence resonant energy transfer (TC-MCFRET) approach in the numerical integration of the Schrödinger equation (NISE) program. This method enables the efficient simulation of incoherent energy transfer between distinct segments within large and complex molecular systems, such as photosynthetic complexes. Our approach incorporates a segmentation protocol to divide these systems into manageable components and a modified thermal correction to ensure detailed balance.

Facilitated transport membranes (FTMs) with an ultraselective layer prepared from amine-rich polyvinylamine (PVAm)/2-(1-piperazinyl)ethylamine salt of sarcosine (PZEA-Sar) (denoted by PM) and an amorphous dendritic cross-linked network of PVAm-functionalized poly(ethylene glycol)diglycidyl ether (PEGDGE) (named PP) were designed for CO separations. The developed membranes expedited CO transport over N through the synergistic effect from the induced CO-philic ethylene oxide groups and highly hydrophilic and polar hydroxyl groups together with the low-crystallinity PP networks, which offer a high diffusion rate for CO-amine complexes through the membrane and stabilize small molecular mobile carriers via hydrogen bonding. The best (PM/PP-10)/polysulfone (PSf) composite membranes achieved a superior CO/N selectivity of 230 (4.

Induction of systemic acquired resistance (SAR) in plants to control bacterial diseases has become an effective solution to the problems of agrochemical resistance and ecological environment damage caused by long-term and large-scale use of traditional bactericides. However, current SAR-inducing compounds are often unable to rapidly eliminate pathogenic bacteria in infected plant tissues to prevent further spread of the disease, severely restraining the potential for extensive application in agriculture. Herein, we address the limitations by developing a series of visible-light-absorbing aggregation-induced emission photosensitizers suitable for agricultural use.

Background: The integration of connected medical devices (MDs) into health care brings benefits but also introduces new, often challenging-to-assess risks related to cybersecurity, which have the potential to harm patients. Current regulations in the European Union and the United States mandate the consideration of these risks in the benefit-risk analysis (BRA) required for MD approval. This important step in the approval process weighs all the defined benefits of a device with its anticipated risks to ensure that the product provides a positive argument for use.
