The self-regulating on cohesion properties of calcium phosphate/ calcium sulfate bone cement improved by citric acid/sodium alginate
Colloids Surf B Biointerfaces. 2023 Sep 16;231:113548. doi: 10.1016/j.colsurfb.2023.113548. Online ahead of print.ABSTRACTCalcium phosphate cement (CPC) has attracted extensive interest from surgeons and materials scientists. However, the collapsibility of calcium phosphate cement limits its clinical application. In this work, a gel network of SA-CA formed by the reaction of citric acid (CA) and sodium alginate (SA) was introduced into the α-TCP/α-CSH composite. Furthermore, a high proportion of α-CSH provided more calcium sources for the system to combine with SA forming a gel network to improve the cohesion property o...

Polysaccharide-Based Composite Hydrogel with Hierarchical Microstructure for Enhanced Vascularization and Skull Regeneration
Biomacromolecules. 2023 Sep 20. doi: 10.1021/acs.biomac.3c00655. Online ahead of print.ABSTRACTCritical-size skull defects caused by trauma, infection, and tumor resection raise great demands for efficient bone substitutes. Herein, a hybrid cross-linked hierarchical microporous hydrogel scaffold (PHCLS) was successfully assembled by a multistep procedure, which involved (i) the preparation of poly(lactic-co-glycolic)/nanohydroxyapatite (PLGA-HAP) porous microspheres, (ii) embedding the spheres in a solution of dopamine-modified hyaluronic acid and collagen I (Col I) and cross-linking via dopamine polyphenols binding to (i)...

Role of S100 and YKL40 on Intraventricular Cerebral Hemorrhages in the Preterm Infant and the Neuroprotective Role of miR-138-siRNAs-HIF-1a and miR-21-siRNAs-HVCN1 in Neonatal Mice with Nerve Injury
CONCLUSION: Our findings demonstrate that miR-138-siRNAs-HIF-1a and miR-21-siRNAs-HVCN1 injections prevent cerebral ischemia-induced brain damage in hypoxia mice by increasing HVCN1 and HIF-1a and decreasing S100b, which in turn lessens apoptosis and epilepsy in hypoxic mice.PMID:37724672 | DOI:10.2174/0929867331666230915103147

Mitochondrial dysfunction at the crossroad of cardiovascular diseases and cancer
J Transl Med. 2023 Sep 19;21(1):635. doi: 10.1186/s12967-023-04498-5.ABSTRACTA large body of evidence indicates the existence of a complex pathophysiological relationship between cardiovascular diseases and cancer. Mitochondria are crucial organelles whose optimal activity is determined by quality control systems, which regulate critical cellular events, ranging from intermediary metabolism and calcium signaling to mitochondrial dynamics, cell death and mitophagy. Emerging data indicate that impaired mitochondrial quality control drives myocardial dysfunction occurring in several heart diseases, including cardiac hypertrop...

Comparative Analysis of First-Line FOLFOX Treatment With and Without Anti-VEGF Therapy in Metastatic Colorectal Carcinoma: A Real-World Data Study
CONCLUSION: Our real-world data analysis suggests that the addition of anti-VEGF to FOLFOX offers limited and short-lived benefits in the context of mCRC and may provide differential survival benefit based on tumor sidedness.PMID:37724508 | DOI:10.1177/10732748231202470

Transient left bundle branch block associated with very high coronary artery calcium: a case report
We present a case of very high CAC in a 64-year-old woman with hypertension, type 2 diabetes, and hyperlipidemia presenting with dyspnea. Initial electrocardiogram (ECG) demonstrated normal conduction with a heart rate of 76 beats/min, but new T-wave inversions in V1-V4 and a high-sensitivity troponin-I (hsTnI) value of 6 ng/L (normal < 6 ng/L). Repeat ECG in the emergency department showed normal sinus rhythm (heart rate of 80 beats/min); however, it subsequently demonstrated a left bundle branch block (LBBB) with a repeat hsTnI of 7 ng/L. Stress testing with pharmacologic single-photon emission computerized tomography...

Phytohormones regulate asexual Toxoplasma gondii replication
Parasitol Res. 2023 Sep 19. doi: 10.1007/s00436-023-07968-3. Online ahead of print.ABSTRACTThe protozoan Toxoplasma gondii (T. gondii) is a zoonotic disease agent causing systemic infection in warm-blooded intermediate hosts including humans. During the acute infection, the parasite infects host cells and multiplies intracellularly in the asexual tachyzoite stage. In this stage of the life cycle, invasion, multiplication, and egress are the most critical events in parasite replication. T. gondii features diverse cell organelles to support these processes, including the apicoplast, an endosymbiont-derived vestigial plastid ...

Structural and functional analysis of salivary intercalated duct cells reveals a secretory phenotype
J Physiol. 2023 Sep 19. doi: 10.1113/JP285104. Online ahead of print.ABSTRACTCurrently, all salivary ducts (intercalated, striated and collecting) are assumed to function broadly in a similar manner, reclaiming ions that were secreted by the secretory acinar cells while preserving fluid volume and delivering saliva to the oral cavity. Nevertheless, there has been minimal investigation into the structural and functional differences between distinct types of salivary duct cells. Therefore, in this study, the expression profile of proteins involved in stimulus-secretion coupling, as well as the function of the intercalated du...

Impacts of Some Trace Metals in Cyprinus carpio (Linnaeus, 1758) and Tor soro (Valenciennes, 1842) on Human Health
Biol Trace Elem Res. 2023 Sep 19. doi: 10.1007/s12011-023-03852-4. Online ahead of print.ABSTRACTAlthough fish are rich sources of various trace metals in their bodies, when these metals exceed health safety limits, it becomes a global concern. Fish exposed to trace metal pollution in their aquatic ecosystems can lead to bioaccumulation and transfer to consumers. Monitoring trace metal contamination of fish food is crucial because they can reach humans through the aquatic food chain, resulting in health problems. Therefore, a first attempt was made for the analysis of trace metals in two cyprinid fish species, namely Cypri...
