Background: Sickle cell diseases (SCDs) are chronic inflammatory processes on capillary level. We tried to understand whether or not there are some positive correlations between acute chest syndrome (ACS) and severity of SCDs.
Methods: All patients with the SCDs were taken into the study.
Results: The study included 337 cases (167 females). There were 15 patients (4.4%) with the ACS. The mean ages were similar in both groups (29.4 versus 29.7 years in the ACS group and other, respectively, P > 0.05). The female ratios were similar in both groups, too (60.0% versus 49.0%, respectively, P > 0.05). Additionally, prevalences of associated thalassemia minors were similar in them (66.6% versus 65.5%, respectively, P > 0.05). Smoking was higher in the ACS group (20.0% versus 13.9%), but the difference was nonsignificant (P > 0.05). Although the mean white blood cell count and hematocrit value of peripheric blood were higher in the ACS group, the mean platelet count was lower in them, but the differences were nonsignificant again (P > 0.05 for all). On the other hand, although the painful crises per year, tonsilectomy, priapism, ileus, digital clubbing, pulmonary hypertension, rheumatic heart disease, cirrhosis, stroke, and mortality were higher in the ACS group, the difference was only significant for the stroke (P < 0.05), probably due to the small sample size of the ACS group.
Conclusion: SCDs are chronic destructive processes on capillaries iniatiating at birth, and terminate with early organ failures in life. Probably ACS is one of the terminal consequences of the inflammatory processes that may indicate shortened survival in such patients.

Polymer based nanoformulations offer substantial prospects for efficacious chemotherapy delivery. Here, we developed a pH-responsive polymeric nanoparticle based on acidosis-triggered breakdown of boronic ester linkers. A biocompatible hyaluronic acid (HA) matrix served as a substrate for carrying a doxorubicin (DOX) prodrug which also possesses natural affinity for CD44 cells.

Adhesives have garnered significant interest recently due to their application in the field of biomedical applications. Nonetheless, developing adhesives that exhibit robust underwater adhesion and possess antimicrobial properties continues to pose a significant challenge. In this study, motivated by the adhesive mechanism observed in mussels in aquatic environments, dopamine (DA) was added to modify the silk fibroin (SF) solution.

With the applications of in situ X-ray diffraction (XRD), electrical - measurement, and ambient pressure hard X-ray photoelectron spectroscopy (AP-HAXPES), the characteristics of the topotactic phase transition of LaCoO (LCO) thin films are examined. XRD measurements show clear evidence of structural phase transition (SPT) of the LCO thin films from the perovskite (PV) LaCoO to the brownmillerite (BM) LaCoO phases through the intermediate LaCoO phase at a temperature of 350 °C under high-vacuum conditions, ∼10 mbar. The reverse SPT from BM to PV phases is also found under ambient pressure (>100 mbar) of air near 100 °C.

Three new bithiophene imide (BTI)-based organic small molecules, (), (), and (), with varied alkyl side chains, were developed and employed as self-assembled monolayers (SAMs) applied to NiOx films in tin perovskite solar cells (TPSCs). The NiOx layer has the effect of modifying the hydrophilicity and the surface roughness of ITO for SAM to uniformly deposit on it. The side chains of the SAM molecules play a vital role in the formation of a high-quality perovskite layer in TPSCs.

Background: Lipoprotein(a) [Lp(a)] is associated with increased cardiovascular risk, but its influence on plaque characteristics at optical coherence tomography (OCT) evaluation is not fully understood.
Aims: This study seeks to explore the impact of Lp(a) levels on plaque morphology as assessed by OCT in a very high-risk subset of patients.
Methods: Consecutive patients admitted for acute coronary syndrome (ACS) and undergoing OCT-guided percutaneous coronary intervention (PCI) at a large tertiary care center between 2019 and 2022 were deemed eligible for the current analysis.
