Proteus mirabilis forms dense crystalline biofilms on catheter surfaces that occlude urine flow, leading to serious clinical complications in long-term catheterized patients, but there are presently no truly effective approaches to control catheter blockage by this organism. This study evaluated the potential for bacteriophage therapy to control P. mirabilis infection and prevent catheter block...

As pulse detonation engine development matures, it becomes increasingly important to consider how practical details such as the implementation of valves and nozzles will affect performance. Inlet valve timing and valveless inlet designs may result in flow of products back upstream and, consequently, reduction in impulse over the ideal case. Although proper inlet design or operation under flowin...

Phacoemulsification is the technique of choice for most cataract surgeons worldwide. This technique can have complications at any of its stages, including intra or post-operative stages. The frequency of the presentation of intraoperative complications varies according to the surgeon’s experience [1], the type of cataract and whether suitable instruments are used [2]. Capsular blockage syndrome...

Colchicine as a vascular disrupting agent creates microtubule destabilization which induces vessel blockage and consequently cell death. Accordingly, colchicines and its analogues radiolabeled with 99mTc may have potential for visualization of tumor. In this work, deacetylcolchicine a colchicine analogue was labeled with 99mTc via tricine as a coligand and characterized for its tumor targeting ...

The blood and lymphatic vasculatures are structurally and functionally coupled in controlling tissue perfusion, extracellular interstitial fluids, and immune surveillance. Little is known, however, about the molecular mechanisms that underlie the regulation of bloodlymphatic vessel connections and lymphatic perfusion. Here we show in the adult zebrafish and glass catfish (Kryptopterus bicirrhis...

Ovarian hyperstimulation syndrome (OHSS) is rare but most serious complication of ovarian stimulation. Symptoms are mainly related to increased capillary permeability leading to extravasation of fluid into extravascular compartment. Disease pathophysiology is linked to hCG (human chorionic gonadotropin) which acts through angiogenic molecule vascular endothelial growth factor (VEGF). There is r...

Patency of the femoral artery of infants and children who previously had percutaneous arterial catheterization at a weight of less than 25 kg was studied angiographically. During the study period, 118 patients had repeat arterial catheterization. 48 from the opposite leg. Femoral artery occlusion was found in four patients, while 44 of the 48 studied from the opposite leg had complete patency. ...

Maternal vitamin A intake varies but its impact on offspring metabolic health is unknown. Here we found that maternal vitamin A or retinoic acid (RA) administration expanded PDGFRα+ adipose progenitor population in progeny, accompanied by increased blood vessel density and enhanced brown-like (beige) phenotype in adipose tissue, protecting offspring from obesity. Blockage of retinoic acid signa...
