Development and application of a comprehensive numerical simulation model for microalgal pneumatic photobioreactors.

A novel and comprehensive multiphysics numerical simulation model for microalgal pneumatic photobioreactors was developed using the open-source Computational Fluid Dynamics (CFD) software OpenFOAM. This model integrates three distinct submodels: multiphase fluid dynamics, light transport, and microalgae growth. In particular, the light transport submodel accounts for light scattering caused by air bubbles.

SS-31 modification alleviates ferroptosis induced by superparamagnetic iron oxide nanoparticles in hypoxia/reoxygenation cardiomyocytes.

Superparamagnetic iron oxide nanoparticles (SPION) are widely used in cardiovascular applications. However, their potential to induce ferroptosis in myocardial cells post-ischemia-reperfusion hinders clinical adoption. We investigated the mechanisms behind SPION-induced cytotoxicity in myocardial cells and explored whether co-loading SPION with SS-31 (a kind of mitochondrial-targeted antioxidant peptide) could counteract this toxicity.

Multi Omics Analysis Revealed a Resistance Mechanism of Tibetan Barley ( L., Qingke) Infected by .

Tibetan barley ( L., qingke) is the principal cereal cultivated on Tibet. causing covered smut is a serious disease that limits the yield of qingke.

Epidermal Cyst Mimicking Thyroid Cancer Metastasis.

A 26-year-old woman with pulmonary metastasis of thyroid cancer underwent a total thyroidectomy and cervical lymph node dissection followed by 2 courses of 131I therapy. The posttherapeutic whole-body scan after the second dose of 131I therapy showed diffuse tracer uptake in both lungs. Besides this, there is a local abnormal radiotracer uptake in the left axillary region.

Virulence Variability and Genetic Diversity in f. sp. in Southeastern and Southwestern China.

Powdery mildew is a key airborne foliar disease of barley in southeastern and southwestern China. Barley varieties usually partially or wholly lose resistance to the pathogen (DC.) f.

Peptide-based 68Ga-PET radiotracer for imaging CD133 expression in colorectal cancer.

Objective: CD133 is a demonstrated cancer stem cell marker. A small peptide LS7, screened by a phage display technique, was identified to specifically target CD133. The purpose of this study was to develop a novel and specific peptide-based PET imaging agent for CD133 imaging in colorectal cancer.

False-Positive Uptake of 131I From Basal Cell Papilloma in a Patient With Metastatic Papillary Thyroid Cancer.

A 64-year-old woman with metastatic papillary thyroid cancer underwent a total thyroidectomy followed by 2 courses of 131I therapy. The posttherapeutic whole-body scan after the second dose of 131I therapy showed multifocal bone metastasis. In addition, there is focal abnormal intense radiotracer uptake at the right inguinal region.

Demonstration of Double Bladder Diverticula on Bone Scan.

A 75-year-old man with suspected prostate cancer underwent a 99mTc-MDP bone scan to exclude the possibility of bone metastasis. Scans revealed areas of increased tracer uptake in a symmetric distribution on both sides of the pelvis. Further SPECT/CT imaging showed focal 99mTc-MDP accumulation within 2 cystic lesions on both sides of the bladder.

Usefulness of ECG to differentiate apical hypertrophic cardiomyopathy from non-ST elevation acute coronary syndrome.

Background: Apical hypertrophic cardiomyopathy (ApHCM) is a phenotypic variant of nonobstructive HCM. ApHCM is characterized by left ventricular hypertrophy involve the distal apex. The electrocardiographic character of ApHCM can mimic non-ST elevation acute coronary syndrome (NSTEACS), triggering a series of studies and treatments that may be unnecessary.

Increased 131I Accumulation in the Gallbladder and High-grade Serous Ovarian Adenocarcinoma.

It is unusual to observe I accumulation in the gallbladder and high-grade serous ovarian adenocarcinoma during posttherapeutic I scan. We report the case of a 55-year-old woman with papillary thyroid cancer, who received total thyroidectomy and then 3 courses of I therapy. The posttherapeutic whole-body scan after the third dose of I therapy revealed abnormal I uptake in the right upper abdomen, overlapping the liver, and the pelvis.
