Objective: To investigate the diagnostic efficacy of the clinical ultrasound imaging model, ultrasonographic radiomics model, and comprehensive model based on ultrasonographic radiomics for the differentiation of small clear cell Renal Cell Carcinoma (ccRCC) and Renal Angiomyolipoma (RAML).
Methods: The clinical, ultrasound, and contrast-enhanced CT(CECT) imaging data of 302 small renal tumors (maximum diameter ≤ 4cm) patients in Tianjin Medical University Cancer Institute and Hospital from June 2018 to June 2022 were retrospectively analyzed, with 182 patients of ccRCC and 120 patients of RAML. The ultrasound images of the largest diameter of renal tumors were manually segmented by ITK-SNAP software, and Pyradiomics (v3.

Bear bile powder (BBP) is widely used in the clinic and has a hypoglycemic effect, but its mechanism is not clear. In this study, type 2 diabetes mellitus (T2DM) rats induced by a high-sugar and high-fat diet combined with streptozotocin were given BBP, and biochemical indexes, pathological sections, metabonomics, intestinal microbiota (IM) and short-chain fatty acids (SCFAs) were determined. The results showed that BBP could reduce blood glucose, relieve inflammation, insulin resistance, and lipid metabolism disorder, and alleviate tissue damage of the liver, spleen, kidney, and pancreas in T2DM rats.

Firstly, by analyzing the sound field distribution characteristics of the sensor in a metal wall, this paper proposes the concept of an "energy circle" and discusses how to calculate echo energy under three different states in detail. Meanwhile, an ultrasonic transmitting and receiving circuit is designed to convert the echo energy inside the energy circle into its equivalent electric power.

Reproductive failure is a major medical issue adversely affecting human health in the 21st century. Many factors contribute to infertility, including immune conditions which may lead to immune infertility (immunologic infertility).

Objective: To explore the diagnostic value of thyroid microcarcinoma with a taller-than-wide shape (A/T ≥ 1) in transverse ultrasonographic planes.
Methods: There were a total of 683 thyroid nodules in 491 patients undergoing consecutive ultrasonography and surgery at our hospital between 2011 and 2012. The ultrasonography examinations of thyroid nodules were routinely performed in the transverse planes.

MicroRNAs (miRNAs) are ~22-nucleotide noncoding RNAs that play a crucial role in regulating muscle development. Our previous study shows that miR-206 is specifically expressed in tilapia skeletal muscle, and exhibits a dynamic expression pattern at different developmental stages. Here, we reveal that miR-206 emerges as a crucial regulator of tilapia growth.
View Article and Find Full Text PDFMyoD is one of the helix-loop-helix proteins regulating muscle-specific gene expression in tilapia. Tight regulation of the MyoD protein level is necessary for the precise regulation of skeletal muscle development. MicroRNAs (miRNAs) are a class of regulatory RNAs that post-transcriptionally regulate gene expression.

The Nile tilapia represents an excellent model for osmoregulation study. Osmotic stress transcription factor 1 (OSTF1) identified in tilapia gill epithelium is a critical element of osmosensory signal transduction by means of transcriptional regulation. Thus, tight regulation of OSTF1 level is necessary for tilapia osmotic adaptation.
View Article and Find Full Text PDFmiRNAs comprise a class of ~22 nt noncoding RNAs that modulate the stability and/or translational potential of their mRNA targets. Emerging data suggest that stress conditions can alter the biogenesis of miRNAs, thereby changing the expression of mRNA targets. Here, we reveal that miR-30c, a kidney-enriched miRNA, emerges as a crucial osmoregulator in Nile tilapia.

Objective: To evaluate the relationship between different hCG priming-to-oocyte retrieval intervals and assisted reproductive technology (ART) outcome.
Methods: We systematically searched PubMed, EMBASE, the Cochrane Library, Science Citation Index, Chinese biomedicine (CBM) literature database, and Chinese Journal Full-text Database for randomized controlled trials (RCTs) published up to November 2010. Data was extracted from the studies by two independent reviewers.

Brg- or hBrm-associated factor (BAF) complexes, a chromatin-remodeling complex family of mammalian cells, facilitate transcriptional activity by remodeling nucleosome structure. Brg1 is the core subunit of Brg-associated factor complexes. In the present study, we investigated the spatial relationship between Brg1 and nuclear factor 1 (NF1/CTF) and RNA polymerase II (RNAP II) upon gene transcriptional activation in vivo by employing immuno-gold labeling.
