Selenium (Se) is an essential trace mineral that plays an important role in physiological processes by regulating the antioxidant defense system and enhancing immunity. Chromium is an essential mineral involved in carbohydrate and lipid metabolism and also plays a role in maintaining normal insulin function. Based on these advantages, we hypothesized that the addition of selenomethionine (SeMet) and organic chromium (OC) to broiler diets would increase Se deposition, antioxidant capacity and immune response in meat.

The development of conductive metal-organic frameworks (MOFs) presents a unique challenge in materials chemistry because it is unclear how to dope them. Here, we demonstrate that the inclusion of pendant amines on hexahydroxytriphenylene linkages results in two-dimensional (2D) polycrystalline frameworks Cu(HHTATP), isostructural to its Cu(HHTP) parent, and exhibits the highest electrical conductivity of 1.21 S/cm among 2D MOFs featuring CuO metal nodes.

Background: Neutrophilic asthma (NA) is a severe asthma phenotype associated with steroid resistance and IL-1β overproduction; however, the exact mechanism remains unclear. Moreover, the dysfunction of TNF-α signaling pathway, a regulator of IL-1β production, was associated with the deficiency of ovarian tumor protease deubiquitinase with linear linkage specificity (otulin) in autoimmune patients.

Objective: We hypothesized that otulin downregulation in macrophages (Mφ) could trigger Mφ activation via the nucleotide-binding domain, leucine-rich repeat, and pyrin domain-containing protein 3 (NLRP3) inflammasome signaling pathway.

Article Synopsis
  • Rheumatoid arthritis (RA) is a chronic autoimmune disease leading to joint inflammation and destruction of cartilage and bone.
  • A study explored the effects of Vigeo, a fermented mixture, on RA symptoms using a collagen-induced arthritis (CIA) mouse model, where mice showed typical RA symptoms after treatment.
  • Results indicated that Vigeo significantly reduced joint inflammation and cartilage damage while lowering levels of inflammatory markers TNF-α, IL-6, and IL-1β in the serum, suggesting its potential as a therapeutic agent for RA.

Background: Transcranial direct current stimulation (tDCS) has been used for the restoration of awareness in patients with a minimal consciousness state (MCS). Most brains of patients in MCS may structurally and electrophysiologically differ from un-damaged brains. Moreover, tDCS is currently contraindicated for patients with craniotomy or skull with metallic implants.

Enzymes in nature efficiently catalyze chiral organic molecules by elaborately tuning the geometrical arrangement of atoms in the active site. However, enantioselective oxidation of organic molecules by heterogeneous electrocatalysts is challenging because of the difficulty in controlling the asymmetric structures of the active sites on the electrodes. Here, we show that the distribution of chiral kink atoms on high-index facets can be precisely manipulated even on single gold nanoparticles; and this enabled stereoselective oxidation of hydroxyl groups on various sugar molecules.

Impaired cardiac function is associated with cognitive impairment and brain imaging features of aging. Cardiac arrhythmias, including atrial fibrillation, are implicated in clinical and subclinical brain injuries. Even in the absence of a clinical diagnosis, subclinical or prodromal substrates of arrhythmias, including an abnormally long or short P-wave duration (PWD), a measure associated with atrial abnormalities, have been associated with stroke and cognitive decline.

Efficient gene expression requires RNA polymerase II (RNAPII) to find chromatin targets precisely in space and time. How RNAPII manages this complex diffusive search in three-dimensional nuclear space remains largely unknown. The disordered carboxy-terminal domain (CTD) of RNAPII, which is essential for recruiting transcription-associated proteins, forms phase-separated droplets in vitro, hinting at a potential role in modulating RNAPII dynamics.

Excessive osteoclast activity can promote periodontitis-associated bone destruction. The inhibitory mechanisms of strains CMU and CMS1 against periodontitis have not yet been fully elucidated. In this study, we aimed to investigate whether heat-killed (HK) CMU and CMS1 or their respective cell-free supernatants (CFSs) inhibit osteoclast differentiation and bone resorption in response to receptor activator of nuclear factor kappa-B ligand (RANKL)-treated RAW 264.

Article Synopsis
  • The study investigates hindfoot biomechanics in patients with ankle osteoarthritis (OA) by analyzing motion during gait, using a multi-segment foot model and considering factors like OA stage and subtalar compensation.
  • A review of 54 ankles showed no significant differences in overall gait parameters based on subtalar compensation or OA stage, although a notable decrease in sagittal range of motion was found in advanced cases.
  • Findings suggest that while subtalar compensation does not influence spatiotemporal gait parameters, advanced ankle OA leads to reduced hindfoot motion, with coronal movement patterns remaining largely unchanged across different OA stages.

Porous thermoelectric materials offer exciting prospects for improving the thermoelectric performance by significantly reducing the thermal conductivity. Nevertheless, porous structures are affected by issues, including restricted enhancements in performance attributed to decreased electronic conductivity and degraded mechanical strength. This study introduces an innovative strategy for overcoming these challenges using porous BiSbTe (BST) by combining porous structuring and interface engineering via atomic layer deposition (ALD).

Article Synopsis
  • - This study analyzed the carbonate system and air-sea CO exchange in the western inshore waters of South Korea in 2020, highlighting the importance of these areas for accurate estimates of CO fluxes in the southeastern Yellow Sea.
  • - Seasonal changes in seawater CO partial pressure (pCO) were primarily influenced by thermal effects, while in the summer, inshore waters showed significant variability in pCO levels, fluctuating between 185 and 1000 μatm.
  • - Unlike offshore regions, inshore waters less than 20 m deep emitted about 100 Gg C per year into the atmosphere, indicating a need for more detailed observations to improve understanding of air-sea CO exchange dynamics.

The structure and intensity of turbulence in the atmospheric boundary layer (ABL) drive fluxes of sediment, contaminants, heat, moisture, and CO[Formula: see text] at the Earth's surface. Where ABL flows encounter changes in roughness-such as cities, wind farms, forest canopies, and landforms-a new mesoscopic flow scale is introduced: the internal boundary layer (IBL), which represents a near-bed region of transient flow adjustment that develops over kilometers. Measurement of this new mesoscopic scale lies outside present observational capabilities of ABL flows, and simplified models fail to capture the sensitive dependence of turbulence on roughness geometry.
