General population is exposed to dibutyl phthalate (DBP) through continuous use of various consumer products. DBP exhibits its effects mainly on the endocrine and reproductive system but it can also affect the function of the vasculature; however, the underlying mechanisms behind DBP-induced vascular dysfunction are not fully understood. To infer pathways, molecular functions, biological processes, and human diseases associated with DBP exposure, we integrated the toxicogenomic data obtained from the 4-week-long exposure of human vascular endothelial cells (ECs) to three environmentally relevant concentrations of DBP with the in silico analysis. Nine genes were affected by DBP exposure six of the integrin family, VCAM1, ICAM1, and MMP2. As shown by the in silico analysis, changes in DBP-affected genes could affect extracellular matrix and binding of molecules and cells to ECs, thereby altering cell adhesion and migration. Several pathways, molecular functions, and biological processes were further identified to provide insight into the DBP-vascular disease relationships and the potential mechanism of action. The top three human disease categories associated with DBP exposure and vascular dysfunction include cardiovascular, cerebrovascular, and immune system diseases. Integration of experimental and in silico approaches may offer better understanding of the potential human health risks associated with DBP exposure.

RUNX Family Transcription Factor 2 (Runx2) promotes neurite outgrowth after sciatic nerve injury, and Curcumin can promote the expression of Runx2. It is worthwhile to explore whether curcumin's repair effect on sciatic nerve injury is related to Runx2.

To investigate the repair effect of curcumin on sciatic nerve injury and its possible mechanism.

Curcumin improved the sciatic functional index (SFI) and toe spread index (TSI) of rats with sciatic nerve injury and increased the number and diameter of myelinated axons in the sciatic nerve. Curcumin promoted the myelination of SCs (Schwann cells) by increasing the expression of peripheral myelin protein 22 (PMP22), fibrin, S100, and proliferating cell nuclear antige (PCNA). Curcumin treatment increased the proliferation of SCs and the expression of Runx2. Cell experiments further confirmed that curcumin promoted Schwann cell proliferation and myelination through Runx2.

Curcumin promotes SCs proliferation and myelination through Runx2 and improves sciatic nerve repair.

Recent studies show that mitochondria or mitochondrial products, as paracrine factors, can be released and transferred from one cell to another. With this information, we were curious to know whether in the SDIA co-culture system, SHED release or donate their mitochondria to ESCs. For this purpose, before co-culture, SHED s' mitochondria and ESCs s' cell membranes were separately labeled with specific fluorescent probes. After co-culture, SHED s' mitochondria were tracked by fluorescent microscope and flow cytometry analysis. Co-culture also performed in the presence of inhibitors that block probable transfer pathways suchlike tunneling nanotubes, gap junctions or vesicles. Results showed that mitochondrial transfer takes place from SHED to ESCs. This transfer partly occurs by tunneling nanotubes and not through gap junctions or vesicles; also was not dependent on intracellular calcium level. This kind of horizontal gene transfer may open a new prospect for further research on probable role of mitochondria on fate choice and neural induction processes.Polyethylene glycol or PEG has a long history of use in medicine. Many conventional formulations utilize PEG as either an active ingredient or an excipient. PEG found its use in biotechnology therapeutics as a tool to slow down drug clearance and shield protein therapeutics from undesirable immunogenicity. Nanotechnology field applies PEG to create stealth drug carriers with prolonged circulation time and decreased recognition and clearance by the mononuclear phagocyte system (MPS). Most nanomedicines approved for clinical use and experimental nanotherapeutics contain PEG. Among the most recent successful examples are two mRNA-based COVID-19 vaccines that are delivered by PEGylated lipid nanoparticles. The breadth of PEG use in a wide variety of over the counter (OTC) medications as well as in drug products and vaccines stimulated research which uncovered that PEG is not as immunologically inert as it was initially expected. Herein, we review the current understanding of PEG's immunological properties and discuss them in the context of synthesis, biodistribution, safety, efficacy, and characterization of PEGylated nanomedicines. We also review the current knowledge about immunological compatibility of other polymers that are being actively investigated as PEG alternatives.

Currently, there are little data on performance, safety, or return to downhill skiing after total joint arthroplasty (TJA). This leaves surgeons with little information for patient counseling regarding skiing.

An online survey was sent to 4360 patients who had undergone at least 1 primary TJA at a single academic center over the past 10 years (4 surgeons). The survey asked patients about their prior and current skiing activity including ability level, limitations, and reoperations. Demographics, patient-reported outcomes, and reoperations were also captured through chart review. Chi-squared, analysis of variance, and t-tests were used to compare demographics and outcomes. AZD0095 mw Paired t-tests were used to compare preoperative and postoperative skiing levels.

Of the 763 survey respondents, the average follow-up was 4.4 years (range 0.5-10.3). In total, 35.6% had never skied, 26.5% had not skied in the 5 years prior to surgery (remote), and 37.9% had skied in the 5 years prior to surgery (recent). Seventy percent of recent skiers returned to skiing after surgery, compared to 11.9% of remote skiers. The majority of skiers, mostly advanced, returned to their prior level. There was no difference in return rates in those with a single total hip arthroplasty vs total knee arthroplasty vs multiple TJAs. Rates of reoperation were not significantly different between patients who did and did not return to skiing.

The majority of recent skiers were able to return to skiing after TJA at their same level without an increase in reoperation rate. Further studies are needed to determine long-term consequences of skiing after TJA.

In 2021, the Centers for Medicare and Medicaid Services (CMS) removed over 200 procedures from the Inpatient Only (IPO) list including revision total hip (THA) and total knee arthroplasties (TKA). The purpose of this study is to determine if some revision TKA and THA procedures may be appropriate for outpatient status.

We reviewed a consecutive series of 1026 revision THA and TKA patients at our tertiary academic institution from 2015 to 2020. An outpatient procedure was defined as a length of stay of <2 midnights. We queried our prospectively collected arthroplasty database and compared demographics, comorbidities, surgical indication, type of procedure, discharge disposition, readmissions, and complications between the outpatient and inpatient groups.

There were only 166 revision patients (16%) who met outpatient criteria. Revision THA outpatients were more likely to have a head and liner exchange (49% vs 25%, P < .001) and an indication of instability (93% vs 44%, P < .001). Revision TKA outpatients were more likely to have an isolated liner exchange (34% vs 14%, P < .001) and have an indication of instability (67% vs 25%, P < .001). Patients undergoing a revision for infection and aseptic loosening were more likely to require an inpatient stay than other revision indication (P < .05).

The vast majority of revision TKA and THA patients met CMS inpatient criteria. In addition to a projected decrease in facility reimbursement, concerns exist for the safety of early discharge and access to care for these complex patients if CMS removes all revisions from the Inpatient Only list.

In this study, the setaria italica somatic embryogenesis receptor-like kinase1 gene (SiSERK1) was cloned by gateway technology, and transferred into a brasssinosteroid (BR) receptor mutant of Arabidopsis thaliana WS2 (bri1-5). After BL treatment, the transgenic plants could partially restore the phenotype of bri1-5. After Pst DC3000 treatment, the CFU value of SiSERK1 overexpression plant pathogen was between WS2 and bri1-5. Stomatal opening and plant height were also between them. Therefore, it is speculated that SiSERK1 gene is involved in BR signaling pathway and can improve the resistance of bri1-5 to Pst DC3000 through SA and NHP mediated systemic acquired resistance (SAR).Stem cell differentiation towards various somatic cells and body organs has proven to be an effective technique in the understanding and progression of regenerative medicine. Despite the advances made, concerns regarding the low efficiency of differentiation and the remaining differences between stem cell products and their in vivo counterparts must be addressed. Biomaterials that mimic endogenous growth conditions represent one recent method used to improve the quality and efficiency of stem cell differentiation, though the mechanisms of this improvement remain to be completely understood. The effectiveness of various biomaterials can be analyzed through a multidisciplinary approach involving bioinformatics and systems biology tools. Here, we aim to use bioinformatics to accomplish two aims 1) determine the effect of different biomaterials on stem cell growth and differentiation, and 2) understand the effect of cell of origin on the differentiation potential of multipotent stem cells. First, we demonstrate that the dimensionality (2D versus 3D) and the degradability of biomaterials affects the way that the cells are able to grow and differentiate at the transcriptional level. Additionally, according to transcriptional state of the cells, the particular cell of origin is an important factor in determining the response of stem cells to same biomaterial. Our data demonstrates the ability of bioinformatics to understand novel molecular mechanisms and context by which stem cells are most efficiently able to differentiate. These results and strategies can be used to suggest proper combinations of biomaterials and stem cells to achieve high differentiation efficiency and functionality of desired cell types.
