The primary nucleotide sequence of the fragment of E1 (gp51-55) gene (772 bp in length) of virulent strain Shi-Min' of classical swine fever virus (CSFV) has been determined. Multiple alignments of the E1 gene fragments of various strains and isolates of CSFV, which are homologues to the cloned fragment, has been carried out; the phylogenetic tree has been plotted and the consensus sequence has been determined. The strain Shi-Min', which was used as a control CSFV strain in former Soviet republics, and the referent strain Alfort were shown to be located on the opposite sides of the dendrogram, while Shi-Min' was more close to the western European group of CSFVs. We suggest that Shi-Min' strain as a positive viral antigen for vaccine testing represents a selective factor for the formation of virus population in Ukraine. The data obtained are the first results in molecular epizootic study of hog cholera in Ukraine.

Assessment of subclinical left ventricular systolic dysfunction in patients with type 2 diabetes: Relationship with HbA1c and microvascular complications.
J Diabetes
March 2023
Department of Endocrinology, Xijing Hospital, Air Force Medical University, Xi'an, Shaanxi, China.
Background: We aimed to examine the association between glycated hemoglobin (HbA1c), microvascular complications, and subclinical left ventricular (LV) systolic dysfunction, and to determine the strength of the correlation in asymptomatic patients with type 2 diabetes mellitus (T2DM).
Methods: Global longitudinal strain (GLS) was employed to assess the subclinical LV function of 152 enrolled T2DM patients with preserved LV ejection fraction, with the cutoff for subclinical LV systolic dysfunction predefined as GLS < 18%.
Results: According to univariate analysis, the reduced GLS exhibited association with the clinical features including HbA1c, triglyceride, systolic blood pressure, fasting glucose, heart rate, diabetic retinopathy, and urinary albumin creatinine ratio (UACR) (all p < .
Association between triglyceride glucose index and subclinical left ventricular systolic dysfunction in patients with type 2 diabetes.

March 2023
Department of Endocrinology, Xijing Hospital, Air Force Medical University, 710032, Xi'an, Shaanxi, China.
Background: The triglyceride glucose (TyG) index has been considered a new biomarker for the diagnosis of angiocardiopathy and insulin resistance. However, the association of the TyG index with subclinical left ventricular (LV) systolic dysfunction still lacks comprehensive exploration. This study was carried out to examine this relationship in patients with type 2 diabetes mellitus (T2DM).

Objective: To develop a reliable and fast assay to quantify the α-synuclein (α-syn)-containing extracellular vesicles (EVs) in CSF and to assess their diagnostic potential for Parkinson disease (PD).
Methods: A cross-sectional, multicenter study was designed, including 170 patients with PD and 131 healthy controls (HCs) with a similar distribution of age and sex recruited from existing center studies at the University of Washington and Oregon Health and Science University. CSF EVs carrying α-syn or aggregated α-syn were quantified using antibodies against total or aggregated α-syn, respectively, and highly specific, sensitive, and rapid assays based on the novel Apogee nanoscale flow cytometry technology.

Background: Microglial function is vital for maintaining the health of the brain, and their activation is an essential component of neurodegeneration. There is significant research on factors that provoke "reactive" or "inflammatory" phenotypes in conditions of injury or disease. One such factor, exposure to the aggregated or oligomeric forms of α-synuclein, an abundant brain protein, plays an essential role in driving microglial activation; including chemotactic migration and production of inflammatory mediators in Lewy body (LB) diseases such as Parkinson's disease.
