Investigation on the Coordination Bonding Nature of Actinide-Doped Endohedral Borospherenes An@B (An = U, Np, Pu, Am, Cm).

Endohedral metallo-borospherenes M@B have received considerable attention since the discovery of B in 2014. However, the coordination bonding nature of most of actinide-doped endohedral An@B still remains in dispute or unexplored. Extensive and systematic first-principles theory calculations performed herein unveil the ground states of triplet U@B (, , A), quartet U@B (, , B), quintet Np@B (, , A), sextet Np@B (, , A), septet Pu@B (, , A), octet Am@B (, , A), and octet Cm@B (, , A) at the coupled-cluster with triple excitations CCSD(T) level.

Observation of Aromatic B(CO) ( = 1-7) as Boron Carbonyl Analogs of Benzene.

CO as a typical σ-donor is one of the most important ligands in chemistry, while planar B is experimentally known as the most prominent magic-number boron cluster analogous to benzene. Joint gas-phase mass spectroscopy, collision-induced dissociation, and first-principles theory investigations performed herein indicate that B reacts with CO successively under ambient conditions to form a series of boron carbonyl complexes B(CO) up to = 7, presenting the largest boron carbonyl complexes observed to date with a quasi-planar B core at the center coordinated by CO ligands around it. Extensive theoretical analyses unveil both the chemisorption pathways and bonding patterns of these aromatic B(CO) monocations which, with three delocalized π bonds well-retained over the slightly wrinkled B moiety, all prove to be boron carbonyl analogs of benzene tentatively named as boron carbonyl aromatics (BCAs).

Associations between body mass index and all-cause mortality among individuals with psoriasis: results from the NHANES database retrospective cohort study.

Background: Previous findings imply a potential positive association between BMI and all-cause mortality in individuals with psoriasis, yet direct evidence remains absent. This study aimed to fill this gap.

Methods: We utilized data from the National Health and Nutrition Examination Survey (NHANES) for the periods 2003-2006 and 2009-2014.

Elevated branched-chain amino acid promotes atherosclerosis progression by enhancing mitochondrial-to-nuclear HO-disulfide HMGB1 in macrophages.

As the essential amino acids, branched-chain amino acid (BCAA) from diets is indispensable for health. BCAA supplementation is often recommended for patients with consumptive diseases or healthy people who exercise regularly. Latest studies and ours reported that elevated BCAA level was positively correlated with metabolic syndrome, diabetes, thrombosis and heart failure.

A secured internet of robotic things (IoRT) for long-term care services in a smart building.

Long-term care refers to any support, both medical and non-medical, provided to the elderly with a chronic illness or disability due to physical or mental conditions. Since the cost of long-term care insurance is not inexpensive, low-cost devices and sensors can be used to create medical assistance systems to reduce human maintenance costs. The requirement of security and privacy under healthcare information protection is a critical issue for internet of medical things (IoMT) data transmission.

Angiotensin II prompts heart cell apoptosis via AT1 receptor-augmented phosphatase and tensin homolog and miR-320-3p functions to enhance suppression of the IGF1R-PI3K-AKT survival pathway.

Background: Hypertension is a severe public health risk factor worldwide. Elevated angiotensin II (Ang II) produced by the renin-angiotensin-aldosterone system can lead to hypertension and its complications.

Method: In this study, we addressed the cardiac-injury effects of Ang II and investigated the signaling mechanism induced by Ang II.

Transition-metal-like bonding behaviors of a boron atom in a boron-cluster boronyl complex [(η-B)-B-BO].

Boron displays many unusual structural and bonding properties due to its electron deficiency. Here we show that a boron atom in a boron monoxide cluster (BO) exhibits transition-metal-like properties. Temperature-dependent photoelectron spectroscopy provided evidence of the existence of two isomers for BO: the main isomer has an adiabatic detachment energy (ADE) of 4.

LncUBE2R2-AS1 acts as a microRNA sponge of miR-302b to promote HCC progression via activation EGFR-PI3K-AKT signaling pathway.

Hepatocellular carcinoma (HCC) is a main cause of cancer-related deaths globally. Long non-coding RNAs (lncRNAs) play important roles in diverse cancers. LncRNA-UBE2R2-AS1 has been reported to promote apoptosis in glioma cell.

Effects of water exchange rate on morphological and physiological characteristics of two submerged macrophytes from Erhai Lake.

Growth patterns of aquatic macrophytes have been shown to vary in response to hydrological properties; however, such properties are typically characterized by water level fluctuation, flow velocity, flooding season, and sedimentation, but not by water exchange rate (WER). Herein, we experimentally investigated how WER (three levels: exchange 0%, 20%, and 40% of total water per day) affects water and sediment properties, and the consequences that these variations have on the individual responses of two submerged macrophytes, and which were planted in two different sediment types (sand and clay). In the experiment without ramets, it was found that turbidity, pH value, and dissolved carbon dioxide concentration of the system water were statistically unaffected by WER, while water dissolved oxygen (DO) concentration and sediment oxidation-reduction potential (ORP, in both sediments) consistently increased with increasing WER, regardless of experimental time.
