Biomarkers and Alzheimer's disease: a bibliometric analysis.

Objective: The diagnosis and treatment of biomarkers in Alzheimer's disease has emerged as a prominent topic within Alzheimer's disease research. In this paper, we conducted a bibliometric analysis of data from a wide range of literature in this field to enhance the in-depth understanding of this area.

Method: The core collection of the Science Citation Index database (web of science) was used to search for relevant literature in the above fields from 1 January 2006 to 14 November 2022 and Citespace software was used to visualize and analyze the literature data.

[Prevention of Spontaneous Premature Birth With Cervical Pessary: A Single-Center Prospective Cohort Study].

Objective: To study and compare the clinical effects of cervical pessary and progesterone for preventing preterm birth in singleton pregnant women with a short cervical length (CL).

Methods: This study was a prospective cohort study. A total of 148 pregnant women with CL≤25 mm, as determined by ultrasound examination performed before 28 weeks of pregnancy, were included in the study.

Association between hypertensive disorders and Bell's palsy in pregnancy: protocol for a systematic review and meta-analysis.

Background: Bell's palsy is an idiopathic peripheral nerve palsy involving the facial nerve. Pregnancy, diabetes mellitus and hypertension are the risk factors for Bell's palsy. However, the association between hypertensive disorders and Bell's palsy during pregnancy or the puerperium remains unclear.

Preoperative moderate to severe anemia is associated with increased postoperative major adverse cardiac and cerebral events and pulmonary complications: a propensity score-matched analysis in hip fracture surgery patients over 80 years old.

Background: Anemia is a common health problem in the elderly. Preoperative anemia is a risk factor for postoperative outcomes in the elderly for hip fracture. The objective of the study was to explore the relationship between preoperative moderate to severe anemia and postoperative morbidity and mortality in hip fracture patients over 80 years old.

Comparative and phylogenetic analysis of complete chloroplast genomes from seven taxa (Lauraceae).

The genus is considered to be one of the most enigmatic groups in Lauraceae, mainly distributed in tropical and subtropical regions of Southeast Asia. The genus contains valuable oilseed and medicinal tree species. However, there are few studies on the genus at present, and its interspecific relationship is still unclear.

Masked Conditional Variational Autoencoders for Chromosome Straightening.

Karyotyping is of importance for detecting chromosomal aberrations in human disease. However, chromosomes easily appear curved in microscopic images, which prevents cytogeneticists from analyzing chromosome types. To address this issue, we propose a framework for chromosome straightening, which comprises a preliminary processing algorithm and a generative model called masked conditional variational autoencoders (MC-VAE).

Preoperative Hemoglobin <10 g/DL Predicts an Increase in Major Adverse Cardiac Events in Patients With Hip Fracture Over 80 Years: A Retrospective Cohort Study.

Background: Preoperative anemia has been associated with perioperative morbidity and mortality in patients undergoing cardiac and non-cardiac surgery. Preoperative anemia is common in elderly hip fracture patients. The primary objective of the study was to explore the relationship between preoperative hemoglobin levels and postoperative major adverse cardiovascular events (MACEs) in hip fracture patients over 80 years.

Mechanics Characteristics of a 3D Star-Shaped Negative Poisson's Ratio Composite Structure.

A negative Poisson's ratio honeycomb material has the characteristics of anti-conventional deformation behavior and high impact resistance, which is a new lightweight microstructure material with broad application prospects. However, most of the current research is still at the microscopic level and two-dimensional level, and little research has been carried out for three-dimensional structures. Compared with the two-dimensional level, three-dimensional negative Poisson's ratio structural mechanics metamaterials have the advantages of a lighter mass, higher material utilization, and more stable mechanical properties, and they have great potential for development in the fields of aerospace, the defense industry, and vehicles and ships.

Trade-offs between xylem hydraulic efficiency and mechanical strength in Chinese evergreen and deciduous savanna species.

Evergreen and deciduous species coexist in tropical dry forests and savannas, but differ in physiological mechanisms and life-history strategies. Hydraulic conductivity and mechanical support are two major functions of the xylems of woody plant species related to plant growth and survival. In this study, we measured sapwood-specific hydraulic conductivity (Ks), leaf-specific hydraulic conductivity (KL), modulus of rupture (MOR) and elasticity (MOE), xylem anatomical traits and fiber contents in the xylems of 20 woody species with contrasting leaf phenology (evergreen vs deciduous) in a Chinese savanna.

The complete plastome sequence of .

, a kind of traditional medicinal liana, belongs to the Blume of the Hernandiaceae. In this study, we reported the characteristics of complete plastome for . Its total plastome was 156,138 bp in length, comprising a large single-copy region(LSC) of 84,931 bp, a small single-copy region (SSC) of 18,544 bp, and a pair of inverted repeat (IR) regions of 26,549 bp.

Observation of the analgesic effect of superficial or deep anterior serratus plane block on patients undergoing thoracoscopic lobectomy.

The effectiveness of anterior serratus plane block in postoperative analgesia of thoracic surgery is beginning to emerge. Currently, there are 2 methods of anterior serratus plane block: deep serratus plane block (DSPB) and superficial serratus plane block (SSPB). In clinical practice, there is no an unified view regarding the advantages and disadvantages between 2 methods.

Whole chloroplast genome sequence of a subtropical tree (Rosaceae).

(Roxb.) is a subtropical plant under the family Rosaceae with high economic and medicinal value. The whole chloroplast genome of was sequenced to better understand its phylogenetic position relative to other Rosaceae species.

Comparison of Combined Lumbosacral Plexus and T12 Paravertebral Nerve Blocks With General Anesthesia in Older Adults Undergoing Primary Total Hip Arthroplasty: A Retrospective, Propensity Score-Matched Cohort Study.

Background: Total Hip Arthroplasty(THA) is a surgical treatment for hip disease. A large amount of evidence has been reported on comparing outcomes of neuraxial(spinal or epidural) anesthesia and general anesthesia. However, it is unclear whether nerve blocks(NB) as main anesthesia technique compared with general anesthesia(GA) for THA could reduce perioperative complications.

Fascia iliaca compartment block versus no block for pain control after lower limb surgery: a meta-analysis.

Background: The analgesic effect of fascia iliaca compartment block (FICB) versus no block (NB) after lower limb surgery (LLS) is still controversial, so we performed this meta-analysis.

Materials And Methods: By searching the PubMed, Embase and the Cochrane Library (last update by July 20, 2017), randomized controlled trials comparing the analgesic effect of FICB versus NB in patients receiving LLS were identified. The primary outcome was the pain scores at 4, 12, and 24 h after LLS.
