Near-infrared brain functional characteristics of mild cognitive impairment with sleep disorders.

Background: Mild cognitive impairment (MCI) has a high risk of progression to Alzheimer's disease. The disease is often accompanied by sleep disorders, and whether sleep disorders have an effect on brain function in patients with MCI is unclear.

Aim: To explore the near-infrared brain function characteristics of MCI with sleep disorders.

The alpha2-adrenoceptor agonist clonidine protects against hypoxic-ischemic brain damage in neonatal mice through the Nrf2/NF-κB signaling pathway.

Neonatal hypoxic-ischemic brain damage (HIBD) is a severe condition closely associated with neuroinflammation and oxidative stress. Clonidine, a selective α2-adrenergic receptor agonist, is known for its anti-inflammatory and antioxidant properties. Despite these recognized therapeutic benefits, the exact mechanisms by which clonidine exerts its effects in the context of HIBD are not fully understood.

Soil conditioner improves soil properties, regulates microbial communities, and increases yield and quality of Uncaria rhynchophylla.

Uncaria rhynchophylla is an important traditional herbal medicine in China, and the yield and quality of Uncaria rhynchophylla can be improved by suitable soil conditioners because of changing the soil properties. In this paper, Uncaria rhynchophylla associated alkaloids and soil microbial  communities were investigated. The field experiment was set up with the following control group: (M1, no soil conditioner) and different soil conditioner treatment groups (M2, biomass ash; M3, water retention agent; M4, biochar; M5, lime powder and M6, malic acid).

Effect of nitrogen reduction by chemical fertilization with green manure (Vicia sativa L.) on soil microbial community, nitrogen metabolism and and yield of Uncaria rhynchophylla by metagenomics.

Uncaria rhynchophylla is an important herbal medicine, and the predominant issues affecting its cultivation include a single method of fertilizer application and inappropriate chemical fertilizer application. To reduce the use of inorganic nitrogen fertilization and increase the yield of Uncaria rhynchophylla, field experiments in 2020-2021 were conducted. The experimental treatments included the following categories: S1, no fertilization; S2, application of chemical NPK fertilizer; and S3-S6, application of chemical fertilizers and green manures, featuring nitrogen fertilizers reductions of 0%, 15%, 30%, and 45%, respectively.

Abnormal hubs in global network as potential neuroimaging marker in generalized anxiety disorder at rest.

Background: Mounting studies have reported altered neuroimaging features in generalized anxiety disorder (GAD). However, little is known about changes in degree centrality (DC) as an effective diagnostic method for GAD. Therefore, we aimed to explore the abnormality of DCs and whether these features can be used in the diagnosis of GAD.

Correlation between Sleep Time, Sleep Quality, and Emotional and Cognitive Function in the Elderly.

Background: To explore the relationship between sleep time, sleep quality, and emotional and cognitive function in the elderly.

Methods: A total of 150 elderly patients over 65 years old who were admitted to our hospital from February 2019 to April 2021 were divided into a normal cognitive function group (Mini-Mental State Examination (MMSE) score: illiteracy, >17; primary school, >20; and middle school and above, >24; = 86) and cognitive impairment group (MMSE score: illiteracy, ≤17; primary school, ≤20; and middle school or above, ≤24; = 64). The sleep quality was evaluated by the Pittsburgh Sleep Quality Index (PSQI), and anxiety and depression were evaluated by Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD), respectively.

[MRI-TRUS targeted biopsy combined with large-section prostate pathology for accurate diagnosis of prostate cancer].

Objective: To investigate the application value of MRI-transrectal ultrasound (TRUS) targeted biopsy combined with large-section prostate pathology in the diagnosis of prostate cancer (PCa).

Methods: Totally, 310 patients with suspected PCa underwent MRI-TRUS targeted biopsy combined with large-section prostate pathology (the observation group, n = 183) or standard 12-core TRUS biopsy (the control group, n = 127) in our hospital from January 2018 to December 2020. We compared the findings of biopsies and the detection rate of PCa between the two groups of patients.

Evaluation of apoptosis induced by exposure to antineoplastic drugs in peripheral blood lymphocytes of nurses.

Cytostatic antineoplastic drugs are considered carcinogenic and mutagenic risk factors for health workers who are occupationally exposed to them; however, the molecular mechanisms underlying these effects remain to be elucidated. Therefore, the present study aimed to investigate the underlying mechanisms of antineoplastic drugs‑induced apoptosis of peripheral blood lymphocytes (PBLs) obtained from oncology nurses handling antineoplastic drugs. A microRNA (miRNA/miR) polymerase chain reaction (PCR) array was performed to analyze the expression levels of miRNAs in the PBLs from 3 trained nurses occupationally exposed to antineoplastic drugs.

Homo- and Copolymerizations of Ethylene and Norbornene Using Bis(β-ketoamino) Titanium Catalysts Containing Pyrazolone Rings.

A series of bis(β-ketoamino) titanium complexes containing pyrazolone rings (⁻) have been synthesized, characterized, and used as precursors for homo- and copolymerization of ethylene and norbornene. The titanium complexes activated with methylaluminoxane (MAO) exhibited good activities for homopolymerization of ethylene (E) to produce linear polyethylenes (PEs). Ethylene⁻norbornene copolymers (E⁻N) were also prepared by these catalysts with moderate activities, and influences of ligand substituents and norbornene addition on copolymer microstructure were studied in detail.

α-Diamine Nickel Catalysts with Nonplanar Chelate Rings for Ethylene Polymerization.

A series of novel α-diamine nickel complexes, (ArNH-C(Me)-(Me)C-NHAr)NiBr , 1: Ar=2,6-diisopropylphenyl, 2: Ar=2,6-dimethylphenyl, 3: Ar=phenyl), have been synthesized and characterized. X-ray crystallographic analysis showed that the coordination geometry of the α-diamine nickel complexes is markedly different from conventional α-diimine nickel complexes, and that the chelate ring (N-C-C-N-Ni) of the α-diamine nickel complex is significantly distorted. The α-diamine nickel catalysts also display different steric effects on ethylene polymerization in comparison to the α-diimine nickel catalyst.

High expression of forkhead box protein C2 is related to poor prognosis in human gliomas.

Background: Increasing evidence has indicated that high Forkhead box protein C2 (FOXC2) level is closely associated with the development, progression, and poor prognosis of a variety of tumors. However, the relationship between FOXC2 and the progression of human gliomas remains to be clarified. The aim of present study was to assess FOXC2 expression and to explore its contribution in human gliomas.
