Thromboelastogram and coagulation function index: relevance for female breast cancer.

Introduction: Screening and postoperative intervention of breast tumors are critical for the effective diagnosis and treatment of disease development, and reliable diagnostic/screening methods become a key link.

Objective: Thromboelastogram (TEG), routine platelet (PLT) count, and the coagulation function indicators in patients with different breast diseases were determined and analyzed to explore their predictive value in secondary bleeding disorders.

Methods: A total of 131 patients with breast diseases, admitted to Jiangsu University Affiliated Hospital from January 2019 to December 2022, were selected as the research subjects.

RNA sequencing identifies key genes involved in intramuscular fat deposition in chickens at different developmental stages.

Background: Intramuscular fat (IMF) is an important factor in meat quality, and triglyceride (TG) and Phospholipids (PLIP), as the main components of IMF, are of great significance to the improvement of meat quality.

Results: In this study, we used 30 RNA sequences generated from the transcriptome of chicken breast muscle tissues at different developmental stages to construct a gene expression matrix to map RNA sequence reads to the chicken genome and identify the transcript of origin. We used weighted gene co-expression network analysis (WGCNA) and identified 27 co-expression modules, 10 of which were related to TG and PLIP.

Formulation and Performance of NBR/CR-Based High-Damping Rubber Composites for Soundproof Using Orthogonal Test.

Multiple functional-material-filled nitrile butadiene rubber/chloroprene rubber (NBR/CR) acoustic composites were extensively studied and prepared. According to the orthogonal test table L25 (5), 25 groups of samples were prepared by using a low-temperature one-time rubber mixing process. With tensile strength, average transmission loss, and damping peak as indexes, the influence degree of different factors and levels on the properties of acoustic composites was quantitatively discussed and analyzed.

[- balance penetrating acupuncture combined with rehabilitation training on upper limb spasticity in stroke hemiplegia].

Objective: To compare the therapeutic effect of - balance penetrating acupuncture combined with rehabilitation training and single rehabilitation training on upper limb spasticity in patients with stroke hemiplegia.

Methods: A total of 60 patients with upper limb spasticity of stroke hemiplegia were randomized into an observation group and a control group, 30 cases in each one. On the basis of conventional western medication, rehabilitation training was adopted in the control group.

Regio- and Stereoselective Steroid Hydroxylation at C7 by Cytochrome P450 Monooxygenase Mutants.

Steroidal C7β alcohols and their respective esters have shown significant promise as neuroprotective and anti-inflammatory agents to treat chronic neuronal damage like stroke, brain trauma, and cerebral ischemia. Since C7 is spatially far away from any functional groups that could direct C-H activation, these transformations are not readily accessible using modern synthetic organic techniques. Reported here are P450-BM3 mutants that catalyze the oxidative hydroxylation of six different steroids with pronounced C7 regioselectivities and β stereoselectivities, as well as high activities.

Biosynthesis of plant tetrahydroisoquinoline alkaloids through an imine reductase route.

Herein, we report a biocatalytic approach to synthesize plant tetrahydroisoquinoline alkaloids (THIQAs) from dihydroisoquinoline (DHIQ) precursors using imine reductases and -methyltransferase (NMT). The imine reductase IR45 was engineered to significantly expand its substrate specificity, enabling efficient and stereoselective conversion of 1-phenyl and 1-benzyl 6,7-dimethoxy-DHIQs into the corresponding ()-tetrahydroisoquinolines (-THIQs). Coclaurine -methyltransferase (CNMT) was able to further efficiently convert these ()-THIQ intermediates into ()-THIQAs.

Pyrazolopyrimidines as Potent Stimulators for Transient Receptor Potential Canonical 3/6/7 Channels.

Transient receptor potential canonical 3/6/7 (TRPC3/6/7) are highly homologous receptor-operated nonselective cation channels. Despite their physiological significance, very few selective and potent agonists are available for functional examination of these channels. Using a cell-based high throughput screening approach, a lead compound with the pyrazolopyrimidine skeleton was identified as a TRPC6 agonist.

Identification and optimization of 2-aminobenzimidazole derivatives as novel inhibitors of TRPC4 and TRPC5 channels.

Background And Purpose: Transient receptor potential canonical (TRPC) channels play important roles in a broad array of physiological functions and are involved in various diseases. However, due to a lack of potent subtype-specific inhibitors the exact roles of TRPC channels in physiological and pathophysiological conditions have not been elucidated.

Experimental Approach: Using fluorescence membrane potential and Ca(2+) assays and electrophysiological recordings, we characterized new 2-aminobenzimidazole-based small molecule inhibitors of TRPC4 and TRPC5 channels identified from cell-based fluorescence high-throughput screening.

Synthesis, biological evaluation and molecular modeling of substituted 2-aminobenzimidazoles as novel inhibitors of acetylcholinesterase and butyrylcholinesterase.

A series of novel 2-aminobenzimidazole derivatives were synthesized under microwave irradiation. Their biological activities were evaluated on acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). A number of the 2-aminobenzimidazole derivatives showed good inhibitory activities to AChE and BuChE.

[Construction of rabbit hemorrhagic disease virus replicons and its replication in RK-13 cells].

To provide an efficient and safe technology platform for studying the replication and pathogenesis mechanisms of RHDV, the interaction between the RHDV and its host cells, a replicon system of RHDV, was constructed based on the infectious cDNA clone of RHDV, in which VP60 gene encoding the capsid protein was deleted, but all the necessary protease coding regions and non-coding regions were retained. Results from RT-PCR, IFA and qRT-PCR confirmed that the replicon RNA could efficiently replicate in RK-13 cells. Besides, the results also suggested that the capsid protein which is the structural protein of RHDV is necessary for maintaining the viral infectivity.
