Wang, Li published the artcileCarboprost tromethamine prevents caesarean section associated postpartum hemorrhage, Category: alcohols-buliding-blocks, the publication is Tropical Journal of Pharmaceutical Research (2020), 19(4), 899-904, database is CAplus.

To investigate the effect of carboprost tromethamine on post-partum hemorrhage associated with caesarean section. One hundred patients with postpartum hemorrhage induced by cesarean section who were admitted to Binzhou People’s Hospital from Oct. 2016 to August 2018 were selected. They were randomly assigned to two groups: control group and treatment group. Patients in the control group were administered oxytocin, while those in the treatment group received oxytocin in combination with carboprost tromethamine. The incidence of hemorrhage and adverse reactions were compared for the two groups. The two groups showed gradually increasing degrees of postpartum hemorrhage within 24 h, but the treatment group had significantly lower volume of postpartum hemorrhage than the control group at different time points (p < 0.05). At the 1st, 3rd and 5th days after delivery, the height of the uterine fundus decreased gradually in the two groups, but was smaller in the treatment group than in the oxytocin group at all time points (p < 0.05). Total response in the treatment group was 98%, which was significantly higher than 78% in the control group (p < 0.05). The incidence of adverse reactions in the treatment group (12%) was significantly lower than that in the control group (24%, p < 0.05). Carboprost tromethamine prevents postpartum hemorrhage after cesarean section. It effectively reduces bleeding and promotes uterine involution, without obvious adverse reactions.

Bhattacharya, Ushashi published the artcileSurface charge manipulation and electrostatic immobilization of synaptosomes for super-resolution imaging: a study on tau compartmentalization, Category: alcohols-buliding-blocks, the publication is Scientific Reports (2021), 11(1), 18583, database is CAplus and MEDLINE.

Synaptosomes are subcellular fractions prepared from brain tissues that are enriched in synaptic terminals, widely used for the study of neural transmission and synaptic dysfunction. Immunofluorescence imaging is increasingly applied to synaptosomes to investigate protein localization. However, conventional methods for imaging synaptosomes over glass coverslips suffer from formaldehyde-induced aggregation. Here, we developed a facile strategy to capture and image synaptosomes without aggregation artifacts. First, ethylene glycol bis(succinimidyl succinate) (EGS) is chosen as the chem. fixative to replace formaldehyde. EGS/glycine treatment makes the zeta potential of synaptosomes more neg. Second, we modified glass coverslips with 3-aminopropyltriethoxysilane (APTES) to impart pos. charges. EGS-fixed synaptosomes spontaneously attach to modified glasses via electrostatic attraction while maintaining good dispersion. Individual synaptic terminals are imaged by conventional fluorescence microscopy or by super-resolution techniques such as direct stochastic optical reconstruction microscopy (dSTORM). We examined tau protein by two-color and three-color dSTORM to understand its spatial distribution within mouse cortical synapses, observing tau colocalization with synaptic vesicles as well postsynaptic densities.

Black, Kvar C. L. published the artcileIn vivo fate tracking of degradable nanoparticles for lung gene transfer using PET and Ĉerenkov imaging, Recommanded Product: Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate, the publication is Biomaterials (2016), 53-63, database is CAplus and MEDLINE.

Nanoparticles (NPs) play expanding roles in biomedical applications including imaging and therapy, however, their long-term fate and clearance profiles have yet to be fully characterized in vivo. NP delivery via the airway is particularly challenging, as the clearance may be inefficient and lung immune responses complex. Thus, specific material design is required for cargo delivery and quant., noninvasive methods are needed to characterize NP pharmacokinetics. Here, biocompatible poly(acrylamidoethylamine)-b-poly(DL-lactide) block copolymer-based degradable, cationic, shell-cross-linked knedel-like NPs (Dg-cSCKs) were employed to transfect plasmid DNA. Radioactive and optical beacons were attached to monitor biodistribution and imaging. The preferential release of cargo in acidic conditions provided enhanced transfection efficiency compared to non-degradable counterparts. In vivo gene transfer to the lung was correlated with NP pharmacokinetics by radiolabeling Dg-cSCKs and performing quant. biodistribution with parallel positron emission tomog. and Cerenkov imaging. Quantitation of imaging over 14 days corresponded with the pharmacokinetics of NP movement from the lung to gastrointestinal and renal routes, consistent with predicted degradation and excretion. This ability to noninvasively and accurately track NP fate highlights the advantage of incorporating multifunctionality into particle design.

Samarajeewa, Sandani published the artcileDegradable Cationic Shell Cross-Linked Knedel-like Nanoparticles: Synthesis, Degradation, Nucleic Acid Binding, and in Vitro Evaluation, Product Details of C18H20N2O12, the publication is Biomacromolecules (2013), 14(4), 1018-1027, database is CAplus and MEDLINE.

In this work, degradable cationic shell crosslinked knedel-like (deg-cSCK) nanoparticles were developed as an alternative platform to replace similar nondegradable cSCK nanoparticles that have been utilized for nucleic acids delivery. An amphiphilic diblock copolymer poly(acrylamidoethylamine)₉₀-block-poly(DL-lactide)₄₀ (PAEA₉₀-b-PDLLA₄₀) was synthesized, self-assembled in aqueous solution, and shell crosslinked using a hydrolyzable crosslinker to afford deg-cSCKs with an average core diameter of 45 ± 7 nm. These nanoparticles were fluorescently labeled for in vitro tracking. The enzymic- and hydrolytic-degradability, siRNA binding affinity, cell uptake and cytotoxicity of the deg-cSCKs were evaluated. Esterase-catalyzed hydrolysis of the nanoparticles resulted in the degradation of ca. 24% of the PDLLA core into lactic acid within 5 d, as opposed to only ca. 9% degradation from aqueous solutions of the deg-cSCK nanoparticles in the absence of enzyme. Cellular uptake of deg-cSCKs was efficient, while exhibiting low cytotoxicity with LD50 values of ca. 90 and 30 μg/mL in RAW 264.7 mouse macrophages and MLE 12 cell lines, resp., ca. 5- to 6-fold lower than the cytotoxicity observed for nondegradable cSCK analogs. Addnl., deg-cSCKs were able to complex siRNA at an N/P ratio as low as 2, and were efficiently able to facilitate cellular uptake of the complexed nucleic acids.

Levesque, Jean Pierre published the artcileA mitogenic fibrinogen receptor that differs from glycoprotein IIb-IIIa. Identification by affinity chromatography and by covalent cross-linking, Computed Properties of 70539-42-3, the publication is Journal of Biological Chemistry (1990), 265(1), 328-33, database is CAplus and MEDLINE.

The mitogenic effect of human fibrinogen on the hemopoietic cell lines Raji and JM is mediate by a specific receptor with biochem. and functional properties different from those of the platelet fibrinogen receptor, the glycoprotein complex IIb-IIIa. This work describes the identification of the mitogenic fibrinogen receptor (MFR) by 2 independent methods, affinity chromatog. and covalent crosslinking. Affinity chromatog. of surface-labeled cell extracts on fibrinogen-Sepharose revealed a 94-kDa membrane protein that bound specifically to fibrinogen-Sepharose only on cells that expressed the MFR. Its mol. mass was not modified after reduction This was confirmed by crosslinking fibrinogen to surface-labeled Raji cells using the cleavable crosslinkers, ethyleneglycolbis(succinimidyl succinate) and dithiobis(succinimidyl propionate). Complexes between fibrinogen and iodinated cell membrane proteins were immunoprecipitated by anti-fibrinogen antibodies. The biochem. cleavage of these immunoprecipitated conjugates gave rise to a 92-kDa membrane protein whose mol. mass was not modified after reduction Thus, fibrinogen binds specifically to a 92-94-kDa MFR which does not belong to the integrin family.

Song, Chengwen published the artcileRole of carboprost tromethamine in laparoscopic myomectomy, COA of Formula: C25H47NO8, the publication is Xuzhou Yixueyuan Xuebao (2013), 33(2), 139-140, database is CAplus.

Hemostatic effect of carboprost tromethamine in laparoscopic myomectomy was discussed. One hundred patients with uterine fibroids were randomly divided into treatment group and control group, they were injected with 1 mL carboprosttromethamine (250 μg) and oxytocin 20 U during operation to prevent bleeding. Bleeding amount, operation time and abdominal drainage in treatment group were less than those in control group (P<0.05). Temperature recovery time and evacuation time by anus had no statistical significance. Application of carboprost tromethamine in laparoscopic myomectomy could significantly decrease bleeding time, shorten operation time, with less adverse reaction and worth popularizing.

Dreiling, Alena published the artcileEarly cleavage of ethylene glycol bis(succinimidylsuccinate) (EGS)-linker moieties during enzymatic digestion of cross-linked proteins, Quality Control of 70539-42-3, the publication is Rapid Communications in Mass Spectrometry (2014), 28(21), 2385-2388, database is CAplus and MEDLINE.

It has become popular to combine the crosslinking of proteins with mass spectrometry (MS) to study their tertiary structure or interactions. There are several difficulties with the method which make it a challenge. They include the limited availability of crosslinked peptides for MS anal. due to low yield of the crosslinking reaction and unwanted side chem. Recently, the authors have pointed out the uncontrolled quenching of azide linkers by buffer components rendering them almost useless for the intended task. Here, the authors describe a phenomenon involving cleavable crosslinkers. They have been designed to overcome the drawback that crosslinked peptides provide poor gas-phase fragmentation mass spectra because of their branched structure. Moreover, isotope coding on such linkers may assist in finding the low-abundance crosslinked peptides in mass spectra as described for ethylene glycol bis(succinimidylsuccinate) (EGS). In some of the authors’ experiments, this compound provided better crosslinking yields compared to other N-hydroxysuccinimide-derived reagents as detected by one-dimensional sodium dodecyl sulfate PAGE. For best results from crosslinking experiments using cleavable agents such as EGS, careful control of sample preparation protocols for early hydrolysis products is advisable.
