Lipid-based Janus nanoparticles for pharmaceutical and cosmetic applications: Kinetics and mechanisms of destabilization with time and temperature. Colloids Surf B Biointerfaces 2020; 195:111242. [PMID: 32652399 DOI: 10.1016/j.colsurfb.2020.111242] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 06/26/2020] [Accepted: 07/02/2020] [Indexed: 01/05/2023]
Abstract
The aim of this paper is to investigate the time and thermal stability of innovative multicompartmental nanoparticles. These particles, having a hydrophilic side and a hydrophobic side, belong to the family of Janus particles and are promising tools to carry active ingredients with opposite solubilities in a unique nanocarrier. The stability of nanoparticles obtained with mainly two types of polyoxylglycerides (Labrafil® M2125 CS and Labrafil® M1944 CS) has been investigated. The suspensions describe a two-step maturation/destabilization process with an Ostwald ripening phase followed by the coalescence of the particles. The effect of lipid composition and temperature on these steps has been investigated in deep as stability with temperature is a critical parameter to consider in order to envisage the development of any formulation for pharmaceutical or cosmetic uses. These nanoparticles were particularly stable at room temperature as their hydrodynamic diameter did not change significantly for 20 months. Contrarily, a strong dependency to temperature appears when storage temperature increases from 25 °C to 43 °C. Indeed, Labrafil® M1944 CS seemed to undergo a progressive destabilization where a significant increase of particles size is visible from 25 °C and phase separation occurred after 4 months at 32 °C. At the opposite, Labrafil® M2125 CS remained stable until 36 °C and reached a threshold temperature between 32 °C and 36 °C after which Labrafil® M2125 CS underwent a consequent increase of particles size at the longer time, i.e. after 6 months. Moreover, Labrafil® M2125 CS formulation was stable at least 3 months at 43 °C.

Abstract
We present two prescriptions for broadband ($ {\sim} 77 - 252\;{\rm GHz} $), millimeter-wave antireflection coatings for cryogenic, sintered polycrystalline aluminum oxide optics: one for large-format (700 mm diameter) planar and plano-convex elements, the other for densely packed arrays of quasi-optical elements-in our case, 5 mm diameter half-spheres (called "lenslets"). The coatings comprise three layers of commercially available, polytetrafluoroethylene-based, dielectric sheet material. The lenslet coating is molded to fit the 150 mm diameter arrays directly, while the large-diameter lenses are coated using a tiled approach. We review the fabrication processes for both prescriptions, then discuss laboratory measurements of their transmittance and reflectance. In addition, we present the inferred refractive indices and loss tangents for the coating materials and the aluminum oxide substrate. We find that at 150 GHz and 300 K the large-format coating sample achieves $ (97 \pm 2)\% $ transmittance, and the lenslet coating sample achieves $ (94 \pm 3)\% $ transmittance.

Abstract
Objective: To analyze the epidemiological characteristics of adult inpatients with gas burns in the Department of Burns of Hwa Mei Hospital of University of Chinese Academy of Sciences (hereinafter referred to as the author's unit) , so as to provide evidence for the prevention of gas burn. Methods: Medical records of all inpatients with flame burns admitted to the author's unit from January 2011 to December 2017 were collected. The percentage of adult inpatients with gas burns in total inpatients with flame burns in the same period, and their gender, age, injury season, accident place, burn severity, common compound injury, complication, population caliber, education, industry, as well as the pre-injury disease and prognosis of elderly inpatients with gas burns were retrospectively analyzed. In addition, the age, accident place, education, and industry of the floating population in the adult inpatients with gas burns were analyzed separately and compared with the total population of adult inpatients with gas burns in 7 years. Data were processed with chi-square test or Fisher's exact probability test (Monte Carlo algorithm). Results: During the 7 years, 1 490 inpatients with flame burns were admitted to the author's unit, among which 511 were adult inpatients with gas burns, accounting for 34.30%. The number of adult inpatients with gas burns increased gradually during the 7 years, but its percentage in the total inpatients with flame burns during the same period showed no significant difference (χ(2)=7.087, P>0.05). Among the 511 adult inpatients with gas burns (hereinafter referred to as the patients in this group), there were 315 males and 196 females, with a male/female ratio of 1.61 to 1.00, and the middle-aged patients were the most, up to 270 cases, accounting for 52.84%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in gender and age (χ(2)=54.810, 27.832, P<0.01). Among the patients in this group, most were injured in summer, totally 251 cases, accounting for 49.12%, and the accident place was mainly at home, totally 388 cases, accounting for 75.93%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in injury season (χ(2)=42.254, P<0.01), but not in accident place (χ(2)=6.782, P>0.05). The patients in this group were mainly with moderate burns (237 cases, accounting for 46.38%), and the distribution trend of burn severity of adult inpatients with gas burns was basically the same during the 7 years (χ(2)=19.680, P>0.05); 176 patients (34.44%) were accompanied by inhalation injury, and 30 patients (5.87%) were accompanied by blast injury of lung; post injury complications occurred in 20 patients (3.91%). In the elderly inpatients with gas burns, 44.44% (32/72) were accompanied by pre-injury basic diseases, and the proportion of death or unhealed reached 18.06% (13/72). Most of the patients in this group were permanent residents (358 cases, accounting for 70.06%) and received secondary education (304 cases, accounting for 59.49%), and the majority of them were engaged in manufacturing/construction (138 cases, accounting for 27.01%), self-employed business (90 cases, accounting for 17.61%), and catering (90 cases, accounting for 17.61%) industries. The distribution of adult inpatients with gas burns during the 7 years was significantly different in population caliber, education, and occupation (χ(2)=17.496, 29.898, 88.896, P<0.05 or P<0.01). Among the patients of this group, the floating population were mainly young (90 cases, accounting for 58.82%) and middle-aged (62 cases, accounting for 40.52%), with main accident place at home (97 cases, accounting for 63.40%), generally received secondary education (101 cases, accounting for 66.01%), and were mainly engaged in manufacturing/construction (71 cases, accounting for 46.41%), self-employed business (26 cases, accounting for 16.99%), and catering (20 cases, accounting for 13.07%) industries. Compared with the total adult inpatients with gas burns in 7 years, the floating population were younger, more injured in the workplace, and more concentrated in industry (χ(2)=42.924, 9.390, 27.819, P<0.01). Conclusions: Gas burn was the leading injury cause of inpatients with flame burns in the author's unit, which mainly occurred in summer and at home; the patients were mainly male, young and middle-aged, and permanent residents, most of which were with moderate burn, often accompanied by inhalation injury. Most of the patients were of secondary education, engaged in manufacturing/construction, self-employed business, and catering industries, among which the floating population were younger, more injured in the workplace, and more concentrated in industry. In order to prevent gas burn, we should pay more attention to the propaganda and education of gas safety among young and middle-aged men, floating population, retired old people and housewives, especially in summer, we should do a good job in gas safety inspection at home. In addition, we should urge enterprises to further strengthen the supervision of production safety.

Abstract
OBJECTIVE How implementing diagnostic-related grouping (DRG) payment affected the use of opioids and psychotropics by hip fracture patients following hospitalization remained unknown. DESIGN A retrospective, pre-post design, cohort study of data excerpted from Taiwan's National Health Insurance Research database (NHIRD). SETTING AND PARTICIPANTS Adults aged ≥ 65 years first admitted for hip fracture surgery from 2007 to 2012 were identified and divided into two 1:1 propensity-score matched groups: pre-DRG (2007-2009); DRG (2010-2012). MEASUREMENTS The outcome measures were use of opioid and/or psychotropic drugs within 30 days, 90 days, 180 days, and 365 days after discharge. RESULTS Data of 16,522 subjects were excerpted, and 8,261 propensity-score matched subjects each classified into the pre-DRG and DRG groups. After adjustment, the DRG group was significantly more likely than the pre-DRG group to have used antipsychotics after discharge from hip fracture surgery (≤30 days, ≤90 days, ≤180 days and ≤365 days). The DRG group also had significantly higher prescription rates of benzodiazepines and antipsychotics during the observation period. Moreover, the DRG group was less likely to use non-steroidal anti-inflammatory drugs (≤30 days, ≤90 days, ≤180 days and ≤365 days) and more likely to use acetaminophen (≤30 days, ≤180 days, and ≤365 days). CONCLUSIONS In conclusion, DRG implementation in Taiwan substantially increased post-acute prescription of antipsychotic and psychotropic agents for hip fracture patients, and changed use of analgesics, which may result in suboptimal quality and safety for these patients. Further research is needed to evaluate the long-term outcomes of DRG implementation, and the potential benefits of appropriate post-acute care bundled with DRG payment.

Abstract
BACKGROUND The Human Cell Atlas is a large international collaborative effort to map all cell types of the human body. Single-cell RNA sequencing can generate high-quality data for the delivery of such an atlas. However, delays between fresh sample collection and processing may lead to poor data and difficulties in experimental design. RESULTS This study assesses the effect of cold storage on fresh healthy spleen, esophagus, and lung from ≥ 5 donors over 72 h. We collect 240,000 high-quality single-cell transcriptomes with detailed cell type annotations and whole genome sequences of donors, enabling future eQTL studies. Our data provide a valuable resource for the study of these 3 organs and will allow cross-organ comparison of cell types. We see little effect of cold ischemic time on cell yield, total number of reads per cell, and other quality control metrics in any of the tissues within the first 24 h. However, we observe a decrease in the proportions of lung T cells at 72 h, higher percentage of mitochondrial reads, and increased contamination by background ambient RNA reads in the 72-h samples in the spleen, which is cell type specific. CONCLUSIONS In conclusion, we present robust protocols for tissue preservation for up to 24 h prior to scRNA-seq analysis. This greatly facilitates the logistics of sample collection for Human Cell Atlas or clinical studies since it increases the time frames for sample processing.

Abstract
We report the first detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB). The lensing signal is obtained using a new estimator that extracts the lensing dipole signature from stacked images formed by rotating the cluster-centered Stokes QU map cutouts along the direction of the locally measured background CMB polarization gradient. Using data from the SPTpol 500 deg^{2} survey at the locations of roughly 18 000 clusters with richness λ≥10 from the Dark Energy Survey (DES) Year-3 full galaxy cluster catalog, we detect lensing at 4.8σ. The mean stacked mass of the selected sample is found to be (1.43±0.40)×10^{14}M_{⊙} which is in good agreement with optical weak lensing based estimates using DES data and CMB-lensing based estimates using SPTpol temperature data. This measurement is a key first step for cluster cosmology with future low-noise CMB surveys, like CMB-S4, for which CMB polarization will be the primary channel for cluster lensing measurements.

Abstract
From June to November 2016, 5 patients with severe burns were admitted to our unit. Broad-spectrum antibiotic and fluconazole were used on patients as earlier empirical anti-infection therapy of bacteria and fungi. Seven to twenty-one days after injury, 5 patients developed fungal infection. Antifungal agents of caspofungin, voriconazole, and amphotericin B liposomewere were used according to the results of fungal culture, and the infected wounds were also treated with repeated debridement and dressing change. Multiple autologous skin grafts were performed after infection control of wounds. With the above antifungal infection treatment for 5 to 11 days, 2 patients' condition tended to be stable, and no fungus was found in wound secretion after cultured for many times. The patients were discharged with wounds healed after 52 to 54 days' hospital stay. Due to severe burns degree and or elder age, fungal infection aggravated and expanded to the trunk in the other 3 patients, then developed into burn sepsis, resulting in patients died of multiple organ failure secondary to sepsis.

Abstract
Objective: To explore whether early oral feeding after total laryngectomy is safe and effective by evaluating the incidence of pharyngocutaneous fistula (PCF) and the hospital duration. Methods: A retrospective cohort study was conducted, including 52 patients underwent total laryngectomy, plus partial tongue base resection (n=2), partial pharyngectomy (n=1), or pedicle flap (n=2) between January 2012 and October 2017. Patients who had a history of preoperative radiotherapy, chemotherapy or chemoradiotherapy, previous surgery for larynx or pharynx and who had severe complications were excluded. Early oral feeding started between 48 h and 72 h postoperatively, while delayed oral feeding started within postoperative day 8-10. The incidences of PCF in two groups were compared to evaluate whether PCF and early oral feeding was related. Multi-variables analysis was conducted to evaluate risk factors for PCF. Results: PCF rate was 19.2% among all patients, 11.1% in patients with early oral feeding and 23.5% in patients with delayed oral feeding. No significant statistically difference in PCF rate was found between two groups (χ(2)=0.506, P=0.477). Multi-variables analysis showed that oral feeding time (early or delayed) was not a independent risk factor of PCF (Two classification response variable Logistic regression, P=0.200, OR=0.242, 95%CI[0.028-2.118]). But low preoperative albumin level was observed as an independent risk factor for PCF (P=0.039, OR=0.848, 95% CI [0.726-0.992]). A negative correlation was observed between preoperative albumin level and PCF. And also there was not a significant difference in hospital duration between patients with early oral feeding and delayed oral feeding(U=268, P=0.464). Conclusion: For patients total laryngectomy with no previous history of radiotherapy, chemotherapy, chemoradiotherapy, early oral feeding after surgery is safe and effective.

Abstract
Background
Patients diagnosed with ductal carcinoma in situ (DCIS) by core needle biopsy (CNB) have a great chance of upgrading invasive cancer on the final pathology. Positive axillary lymph nodes can be found in these patients. The present study sought to identify clinicopathological factors associated with upgrading and axillary lymph nodes metastasis in patients preoperatively diagnosed with DCIS by CNB.
Materials and Methods
This study identified 604 patients (cT1-3N0M0) with preoperative diagnosis of pure DCIS by CNB who had undergone axillary evaluation from August 2006 to December 2015 at Fudan University Shanghai Cancer Center (FUSCC). Predictors of upgrading and axillary lymph nodes metastasis were analyzed, respectively.
Results
Of all 604 patients, 513 (84.93%) and 91 (15.07%) patients had undergone sentinel lymph nodes biopsy (SLNB) and axillary lymph nodes dissection (ALND), respectively. Overall, 121 (20.03%) and 193 (31.95%) patients were upgraded to DCIS with microinvasion (DCISM) and IDC on final pathology, respectively. Positive axillary lymph nodes were identified in 41 (6.79%) patients, of which 35 (5.80%) patients had 1-2 positive axillary lymph nodes, 6 (0.99%) patients had 3 or more positive axillary lymph nodes. Among patients with axillary lymph nodes metastasis, 4 (9.76%), 4 (9.76%) and 33 (80.48%) patients were in DCIS, DCISM and IDC group, respectively. Predictors of upgrading included tumor size on ultrasonography (P=0.001), Ki-67 (P=0.046) and molecular subtype (P=0.007) in univariate analysis. In multivariate analysis, patients with larger tumor size on ultrasonography (>2cm) (OR 1.767, P=0.001) were more likely to be upgraded on final pathology. Also, ER+ HER2+ patients were more likely to be upgraded than ER+ HER2- patients (OR 1.659, P=0.047). Factors associated with axillary lymph nodes metastasis included nipple discharge (P<0.001), tumor size on pathology (P=0.037), number of lesions (P=0.039), axillary evaluation methods (P=0.029) and molecular subtype (P=0.049) in univariate analysis. Whereas, only nipple discharge and larger tumor size on pathology (>2cm) reached statistical significance in multivariate analysis (OR 5.959, P<0.001; OR 2.361, P=0.042). In addition, further analysis showed upgrading on final pathology had a significant influence on axillary lymph nodes status (P<0.001). However, this correlation was not shown between patients with DCIS and DCISM in pairwise comparison.
Conclusion
The data of upgrading and axillary lymph nodes metastasis in patients with an initial diagnosis of DCIS by CNB was comparable in this cohort with published data. Despite of a 51.98% upgrading rate, the rate of axillary lymph nodes metastasis in these patients is low, which supports the omission of axillary evaluation in selected patients.

Abstract
Clarification of TP53 alterations is important to understand the mechanisms underlying the development of diffuse astrocytomas. It has been suggested that the alleles of TP53 at codon 72 differ in their ability to induce apoptosis in human cancers. The aim of this study was to analyze the possible association of TP53 mutation, p53 overexpression, and p53 codon 72 polymorphism with susceptibility to apoptosis in adult Brazilian patients with diffuse astrocytomas. We analyzed 56 surgical specimens of diffuse astrocytomas for alterations of TP53, using polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) direct sequencing. p53 and cleaved caspase 3 protein expression were assessed by immunohistochemistry. We found TP53 mutations in 19.6% (11 out of 56) of tumors tested, with the lowest mutation rate found in the cases of glioblastomas (8.8%) (p = 0.03). Only 16.1% of tumors tested showed cleaved caspase 3-positive staining, demonstrating that apoptosis is very inhibited in these tumors. All tumors having TP53 mutation and p53 accumulation had no expression of cleaved caspase 3. Additionally, no association was observed in tumors having proline and arginine alleles and expression of cleaved caspase 3. We concluded that clarification of the TP53 alterations allows a better understanding of the mechanisms involved in the progression of diffuse astrocytomas, and the allele status at codon 72 was not associated with apoptosis in these tumors.

Abstract
Rabbit haemorrhagic disease virus (RHDV, or GI.1) is a calicivirus in the genus Lagovirus that has been widely utilized in Australia as a biological control agent for the management of overabundant wild European rabbit (Oryctolagus cuniculus) populations since 1996. Recently, two exotic incursions of pathogenic lagoviruses have been reported in Australia; GI.1a-Aus, previously called RHDVa-Aus, is a GI.1a virus detected in January 2014, and the novel lagovirus GI.2 (previously known as RHDV2). Furthermore, an additional GI.1a strain, GI.1a-K5 (also known as 08Q712), was released nationwide in March 2017 as a supplementary tool for wild rabbit management. To discriminate between these lagoviruses, a highly sensitive strain-specific multiplex RT-PCR assay was developed, which allows fast, cost-effective and sensitive detection of the four pathogenic lagoviruses currently known to be circulating in Australia. In addition, we developed a universal RT-qPCR assay to be used in conjunction with the multiplex assay that broadly detects all four viruses and facilitates quantification of viral RNA load in samples. These assays enable rapid detection, identification and quantification of pathogenic lagoviruses in the Australian context. Using these assays, a novel recombinant lagovirus was detected in rabbit tissue samples, which contained the non-structural genes of GI.1a-Aus and the structural genes of GI.2. This variant was also recovered from the liver of a European brown hare (Lepus europaeus). The impact of this novel recombinant on Australian wild lagomorph populations and its competitiveness in relation to circulating field strains, particularly GI.2, requires further studies.

Abstract
Graphitization occurs during the long-term service of a diamond-like carbon (DLC) modified artificial joint. Then, DLC wear debris, which are carbon particles with different sp2/sp3 ratios and sizes ranging from the nano- to micro-meter scale produced. In this paper, to promote the application of DLC coating for artificial joint modification, the cytotoxicity of DLC debris (nano-carbon particles, NCs) with different sp2/sp3 ratios was studied. The microstructure and physical characteristics of NCs with different sp2/sp3 ratios were investigated by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Transmission Electron Microscope (TEM) and Dynamic Light Scattering (DLS). Meanwhile, osteoblasts and macrophages were applied to characterize the cytotoxicity of the NCs. In vitro cytotoxicity assay results indicated that cells incubated with NCs of different sp2/sp3 ratios had greater osteogenic capacity, and these particles caused a weaker immune response in comparison with CoCrMo particles. Taken together, the results indicated that NCs with different sp2/sp3 ratios presented a good cytocompatibility than CoCrMo particles. But no significant differences were observed among NCs with different sp2/sp3 ratios. The better cytocompatibility of NCs is mainly attributable to their surface charge.

Abstract
Patients with DLC (diamond like carbon)-coated artificial joints may be exposed to a wide size range of DLC wear debris (DW). In this study, the cytotoxicity of DW of different size ranges (0-0.22, 0.22-0.65, 0.65-1.0, and 1.0-5.0 μm) was evaluated. The microstructure and physical characteristics of DW were investigated by Raman spectroscopy, transmission electron microscopy (TEM), scanning electron microscope (SEM), and dynamic light scattering (DLS). Macrophages, osteoblasts, and fibroblasts were incubated with DW of different size ranges respectively followed by cytotoxicity evaluations of inflammatory cytokines, alkaline phosphatase (ALP) assays, and related signal protein expression analysis. The results showed that, except for the size range of 0-0.22 μm, DW cytotoxicity showed a size-dependent (0.22-5.0 μm) decrease with increasing size. Within the range of 0.22-5.0 μm, DW of larger size resulted in lessened inflammatory response and enhanced osteoblastogenesis and fibrogenesis, with increased viability of cells (macrophages, osteoblasts, and fibroblasts), better morphology, less release of pro-inflammatory factors and more release of anti-inflammatory factors. The results demonstrated that DW sizes below 0.22 μm had less negative effects on cell adhesion and growth because of the BSA (bovine serum albumin) encapsulation effect. These findings provide valuable knowledge about the comprehensive mechanism of promotion of inflammatory response and inhibition of osteoblastogenesis and fibrogenesis induced by DW. In conclusion, an effective system of biocompatibility evaluation for different sizes of DW was derived.

Abstract
Background Genome wide association studies (GWAS) already have identified tens of susceptible loci for nonsyndromic cleft lip with or without cleft palate (NSCL/P). However, whether these loci associated with nonsyndromic cleft palate only (NSCPO) remains unknown. Material and Methods In this study, we replicated 38 SNPs (Single nucleotide polymorphisms) which has the most significant p values in published GWASs, genotyping by using SNPscan among 144 NSCPO trios from Western Han Chinese. We performed the transmission disequilibrium test (TDT) on individual SNPs and gene-gene (GxG) interaction analyses on the family data; Parent-of-Origin effects were assessed by separately considering transmissions from heterozygous fathers versus heterozygous mothers to affected offspring. Results Allelic TDT results showed that T allele at rs742071 (PAX7) (p=0.025, ORtransmission=3.00, 95%CI: 1.09-8.25) and G allele at rs2485893 (10kb 3’ of SYT14) were associated with NSCPO (p=0.0036, ORtransmission= 0.60, 95%CI: 0.42-0.85). Genotypic TDT based on 3 pseudo controls further confirmed that rs742071 (p-value=0.03, ORtransmission=3.00, 95%CI: 1.09-8.25) and rs2485893 were associated with NSCPO under additive model (p-value= 0.02, ORtransmission= 0.66, 95%CI: 0.47-0.92). Genotypic TDT for epistatic interactions showed that rs4844913 (37kb 3’ of DIEXF) interacted with rs11119388 (SYT14) (p-value=1.80E-08) and rs6072081 (53kb 3’ of MAFB) interacted with rs6102085 (33kb 3’ of MAFB) (p-value=3.60E-04) for NSCPO, suggesting they may act in the same pathway in the etiology of NSCPO. Conclusions In this study, we found that rs742071 and rs2485893 were associated NSCPO from Han Chinese population; also, interactions of rs4844913:rs11119388 and rs6072081:rs6102085 for NSCPO were identified, gene-gene interactions have been proposed as a potential source of the remaining heritability, these findings provided new insights of the previous GWAS. Key words:GWAS, NSCPO, TDT, parent-of-origin effects, epistatic interactions.
