Bioceramics for Guided Bone Regeneration: A Multicenter Randomized Controlled Trial.

Objectives: To compare the clinical effectiveness of a novel bioceramic (BC) with a control xenograft (BO) for guided bone regeneration (GBR) performed simultaneously with implant placement.

Materials And Methods: This clinical study enrolled patients with insufficient bone volume who required GBR during implant placement to increase bone width using either BC or BO. Outcome measures included a dimensional reduction in buccal bone thickness measured by cone beam computed tomography performed immediately post-surgery and at 6 months postoperatively (ΔHBBT), soft tissue healing at 14 days, 1 month, and 6 months postoperatively, and complications rates.

Protocol for evaluating humoral immune responses in mice following SARS-CoV-2 vaccination.

Binding and neutralizing antibodies are critical indicators of protection against viral pathogens and are essential for assessing the immunogenicity and efficacy of a vaccine. Here, we present a protocol comprising two assays for measuring the spike-specific binding and neutralizing antibodies in mouse plasma following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. We describe steps for determining binding antibody titers using enzyme-linked immunosorbent assay (ELISA) and assessing neutralizing antibody titers through a pseudovirus neutralization assay.

Targeting CD45 by gene-edited CAR T cells for leukemia eradication and hematopoietic stem cell transplantation preconditioning.

Hematopoietic stem cell transplantation (HSCT) is widely used to treat patients with life-threatening hematologic and immune system disorders. Current nontargeted chemo-/radiotherapy conditioning regimens cause tissue injury and induce an array of immediate and delayed adverse effects, limiting the application of this life-saving treatment. The growing demand to replace canonical conditioning regimens has led to the development of alternative approaches, such as antibody-drug conjugates, naked antibodies, and CAR T cells.

Creating a Halotolerant Degrader for Efficient Mineralization of p-Nitrophenol-Substituted Organophosphorus Pesticides in High-Saline Wastewater.

The bioaugmentation performance is severely reduced in the treatment of high-saline pesticide wastewater because the growth and degradation activity of pesticide degraders are significantly inhibited by high salt concentrations. In this study, a heterologous biodegradation pathway comprising the seven genes mpd/pnpABCDEF responsible for the bioconversion of p-nitrophenol (PNP)-substituted organophosphorus pesticides (OPs) into β-oxoadipate and the genes encoding Vitreoscilla hemoglobin (VHb) and green fluorescent protein (GFP) were integrated into the genome of a salt-tolerant chassis Halomonas cupida J9, to generate a genetically engineered halotolerant degrader J9U-MP. RT-PCR assays demonstrated that the nine exogenous genes are successfully transcribed to mRNA in J9U-MP.

The energetic carriers generated in nanometal under illumination have extremely short lifetimes, leading to rapid energy loss.

Hysteroscopy combined with laparoscopy in the diagnosis and treatment of omentum majus incarceration secondary to uterine perforation: A case report and literature review.

Cervical dilatation, uterine evacuation, and curettage (D&E&C) are common gynecological procedures for abortion, yet they carry risks of complications such as uterine perforation and intra-abdominal organ incarceration. Here, we report a rare case of a breastfeeding patient who had an embedded abdominal greater omentum in the anterior wall of the uterus and into the uterine cavity during D&E&C. We used combined hysteroscopic and laparoscopic treatment for this case and successfully removed the embedded greater omentum.

Nuclear adenine activates hnRNPA2B1 to enhance antibacterial innate immunity.

Bacterial infection reprograms cellular metabolism and epigenetic status, but how the metabolic-epigenetic crosstalk empowers host antibacterial defense remains unclear. Here, we report that heterogeneous nuclear ribonucleoprotein A2B1 (hnRNPA2B1) is a sensor for metabolite adenine to launch an antimicrobial innate response through increasing Il1b transcription. Myeloid cell-specific Hnrnpa2b1-cKO mice are more susceptible to bacterial infection, while interleukin 1 beta (IL-1β) supplementation rescues the phenotype.

The design of the selenization process significantly affects the quality of the absorber layer.

Pressure Sensor Array Based on Four DNA-Nanoenzymes with Catalase-like Activity for Portable Multiple Detection of Foodborne Pathogens.

This study has developed a pressure sensor array based on four functionalized DNA-nanoenzymes with catalase-like activity for multiple detections of foodborne pathogens through a portable pressure manometer. Benefiting from functionalization of 4-mercaptophenylboronic acid and β-mercaptoethylamine, the diversity of nonspecific interactions between four DNA-nanoenzymes and each of the nine bacteria leads to differences in pressure response patterns by catalyzing HO to generate exclusive "fingerprints". As effective statistical tools for processing multivariate data, principal component analysis and hierarchical clustering analysis are employed to identify nine foodborne pathogens by analyzing pressure response patterns.

Gradient Surface Gallium-Doped Hematite Photoelectrode for Enhanced Photoelectrochemical Water Oxidation.

Hematite is a promising material for photoelectrochemical (PEC) water oxidation, but its photocurrent is limited by bulk charge recombination and poor oxidation kinetics.

Improved analysis of supervised learning in the RKHS with random features: Beyond least squares.

We consider kernel-based supervised learning using random Fourier features, focusing on its statistical error bounds and generalization properties with general loss functions. Beyond the least squares loss, existing results only demonstrate worst-case analysis with rate n and the number of features at least comparable to n, and refined-case analysis where it can achieve almost n rate when the kernel's eigenvalue decay is exponential and the number of features is again at least comparable to n. For the least squares loss, the results are much richer and the optimal rates can be achieved under the source and capacity assumptions, with the number of features smaller than n.
