AI Article Synopsis
- This study evaluates the effectiveness of contrast enhanced ultrasound (CEUS) in diagnosing benign prostatic hyperplasia (BPH) by comparing CEUS parameters between BPH patients and healthy individuals.
- A total of 60 BPH patients and 30 normal controls underwent CEUS, with specific measurements (e.g., arrival time, peak intensity) analyzed to identify differences between the two groups.
- Results showed significant differences in several CEUS parameters, demonstrating a high diagnostic accuracy of 95.6% for BPH, suggesting CEUS can provide an objective assessment for this condition.
Article Abstract
Background: This study aimed to investigate the clinical significance of contrast enhanced ultrasound (CEUS) in diagnosis of benign prostatic hyperplasia (BPH) through comparing CEUS parameters between BPH and normal person.
Methods: A retrospective study of sixty BPH patients (aged 73.5 ± 20.5 years old) and thirty normal controls without prostate diseases (aged 75.3 ± 19.7 years old) who had accepted CEUS detection were performed. Time-intensity curves were obtained for all tests in regions of interest. Images were processed using ACQ software and the following parameters were obtained: arrival time (AT), peak intensity (P), time to peak (TP), area under the curve (AUC), mean transit time (MTT) and extinction time (ET). Differences in inner and outer gland of prostate between BPH and the normal tissue were evaluated.
Results: There was a clear boundary between the inner and outer gland of BPH prostate. AT, TP, MTT, ET and P in BPH outer gland were significantly higher than the control group. In inner gland, MTT, ET, AUC and P were also significantly higher than the controls. The accurate rate to diagnose BPH using CEUS was 95.6%, and the sensitivity and specificity were 95.0% and 96.7%, respectively.
Conclusions: Among these significantly changed parameters, the increases of MTT, ET and AUC in inner gland and AT, TP in outer gland were most likely related to BPH. These parameters provide an objective visual assessment to diagnosis of BPH.

Background: Myoepithelial carcinoma is a very rare yet aggressive tumor in children. Surgical intervention and local radiotherapy often lead to post-therapy complications, affecting both the aesthetic and functional quality of life in survivors. Hyaluronic acid (HA) dermal fillers offer a minimally invasive option to improve the appearance and quality of life for these patients once they are declared tumor-free.

The (bladderworts) species are carnivorous plants that prey mainly on invertebrates using traps (bladders) of leaf origin. On the outer surfaces of the trap, there are dome-shaped glands (capitate trichomes). Each such trichome consists of a basal cell, a pedestal cell, and a terminal cell.

The citrus disease Huanglongbing (HLB) in Asia and the US is caused by Candidatus Liberibacter asiaticus (CLas), which is primarily transmitted by Diaphorina citri, also known as Asian citrus psyllid in a persistent and propagative manner. However, the exact mechanisms underlying CLas circulation within D. citri remain largely unclear.

The abnormal mitochondrial autophagy signaling caused by the putative kinase 1/Parkin E3 ubiquitin protein ligase (Pink1/Parkin) signaling pathway directly affects the normal secretion of melatonin by the pineal gland, which may explain the pathogenesis of depression combined with insomnia. This study aims to explore the depression-like behavior, sleep changes, central oxidative stress response, pineal mitochondrial autophagy damage, melatonin secretion, histopathological changes of the pineal gland, and the expression of Pink1/Parkin signaling-related factors in CUMS+SD rats.

Article Synopsis
- Cockatiels are popular pet birds that often need veterinary care, making it important to understand their digestive system for better treatment.
- This study involved dissecting six cockatiels to analyze and measure their digestive tract, revealing variability in size and specific structural features.
- Key findings included the structure of the oesophagus, stomach, and intestines, along with histological traits that showed similarities to other birds but also unique species-specific characteristics.
