Abstract
Objectives To conduct a qualitative phenomenological study exploring factors for using serving chopsticks and separate dining.
Methods Qualitative phenomenological research was conducted via face-to-face, semi-structured interviews. All interview transcripts were analyzed using the seven steps of Colaizzi phenomenological data analysis and were input into the Nvivo12 (qualitative research analysis software) through sentence-by-sentence, word-by-word coding and formed themes.
Results Two main themes and fifteen sub-themes were found. The barriers in implementing serving chopsticks and separate dining include consumers bearing the cost of serving chopsticks and separate dining in the end; long-established dietary habits and culture background of willingness to share food with others by using own chopsticks or eating in one pot; the difficulty for low-end catering to implement the serving chopsticks and separate dining; separate dining bringing challenges to grasping the quantity of meals given each person’s varying preferences; weak public awareness of serving chopsticks and separate dining; their perception that troublesome and embarrassing, separate dining destroys the overall aesthetic of the food; and no sophisticated design of serving chopsticks and separate dining. Suggestions to implement serving chopsticks and separate dining include pioneering the implementation and training of communal chopsticks sharing in the restaurant industry, the collective units implementing the serving chopsticks system, producing highly recognizable serving chopsticks, creating a living atmosphere of serving chopsticks, promoting the comprehensive government system to form a new "food" fashion, conducting serving chopsticks experience activities, guarantee through government mandatory policies starting with teenagers, prioritizing the implementation of serving chopsticks, and gradually promoting the serving chopsticks system.
Conclusions Mandatory government policies and measures, public education on serving chopsticks, creating a good atmosphere for serving chopsticks, the production and sale of recognizable chopsticks and reasonable separate dining design, and the initiative of the catering industry and unit canteens to assume the responsibility of chopsticks sharing are required.

Abstract
Background: Menopause is a physiologic phase in women’s lives. Finding regarding MS course through menopause is diverse and we designed this systematic review and meta-analysis to estimate impact of menopause on relapse rate, and disability status.
Methods: PubMed, Scopus, EMBASE, Web of Science, google scholar were systematically searched by two independent researchers on January 1st 2023. They also evaluated conference abstracts and references of the references. Data regarding the total number of participants, first author, publication year, country of origin, disease duration, disease type, annual relapse rate, and Expanded Disability Status Scale (EDSS) before and after menopause were recorded.
Results: A literature search revealed 1024 records, after deleting duplicates we had 660 records. Twenty-one full texts were evaluated, and finally four studies remained for meta-analysis. Mean ARR before menopause ranged between 0.21 and 0.37, and after menopause ranged between 0.13 and 0.08.
The SMD of menopause ranged between -1.04, and -0.29, while the pooled SMD was estimated as -0.52(95% CI: -0.88, -0.15)(I2=73.6%, P=0.02). Mean EDSS before menopause ranged between 1.5 and 2, and after menopause ranged between 2 and 3.1. the SMD of EDSS ranged between 0.46, and 0.71. The pooled SMD of EDSS change estimated as 0.56(95% CI: 0.38, 0.73)(I2=0, P=0.4).
Conclusion: The result of this systematic review and meta-analysis show that menopause cause a decrease in relapse rate, unlike an increase in disability status.

Published: March 2023

Abstract
Background
Pathological examination by endoscopic ultrasonography–guided fine-needle aspiration (EUS-FNA) has been reported to be useful in diagnosing pancreatic malignant lymphoma (ML), but some ML cases are difficult to be differentiated from pancreatic ductal adenocarcinoma (PDAC).
Methods
This retrospective study included 8 patients diagnosed with ML that had a pancreatic-head lesion at initial diagnosis and 46 patients with resected PDAC in the pancreatic head between April 2006 and October 2021 at our institute. ML and PDAC were compared in terms of patients’ clinical features and imaging examinations.
Results
The median tumor size was larger in ML than in PDAC (45.8 [24–64] vs. 23.9 [8–44] mm), but the median diameter of the caudal main pancreatic duct (MPD) was larger in PDAC (2.5 [1.0–3.5] vs. 7.1 [2.5–11.8] mm), both showing significant differences between these malignancies (both, P < 0.001). In the analysis of covariance, MLs showed a smaller caudal MPD per tumor size than PDACs, with a statistical difference. Sensitivity and specificity using sIL-2R ≥ 658 U/mL plus CA19-9 < 37 U/mL for the differentiation of ML from PDAC were 80.0% and 95.6%, respectively (P < 0.001).
Conclusions
Diagnosing pancreatic ML using cytohistological examination through EUS-FNA can be difficult in some cases. Thus, ML should be suspected if a patient with a pancreatic tumor has a small MPD diameter per tumor size, high serum sIL-2R level, normal CA19-9 level. If the abovementioned features are absent and still cannot be confirmed as PDAC, re-examination should be considered.

Published: March 2023

Abstract
Object: This study was to investigate the effect of different human Menotrophin (hMG) initiation doses on in vitro fertilization (IVF) outcomes in aged poor ovarian response(POR) patients undergoing ovulation induction with Clomiphene Citrate (CC) combined with hMG; Method: The clinical data of 142 POR patients more than 40 years old were collected and were divided into 3 groups according to the initiation dose of hMG (Group A=75IU, Group B=150IU, Group C=225IU). The baseline characteristics and IVF outcomes were compared; Results: We found that with the increase of hMG initiation dose, the average number of oocytes retrieved increased, pair-to-pair comparison showed that the the average number of oocytes retrieved in Group Awas significantly lower than that in the Group B and Group C(P<0.05). Compared with Group B, the fertilization rate and oocyte utilization rate of patients in Group C were significantly lower (P<0.05). There was no significant difference in MII oocyte rate, Cleavage rate, embryo formation rate, high-quality embryo rate and pregnancy outcomes among the three groups(P>0.05). Conclusions: For aged POR patients receiving CC combined with hMG, increasing hMG cannot improve patients' IVF outcomes and Pregnancy outcomes. 150IU of hMG initiation dose may be the better choice for aged POR patients.

Abstract
Background
Maintaining people living with HIV (PLWHIV) in clinical care is a global priority. In the Metro Detroit area of Michigan, approximately 30% of PLWHIV are out of care. To re-engage lost-to-follow-up patients, Wayne Health Infectious Disease clinic launched an innovative Homecare program in 2017. In addition to home healthcare delivery, the program included links to community resources and quarterly community meetings. We aimed to evaluate Homecare’s impact on participants’ ability to stay engaged in HIV care and reach viral suppression. We included data from PLWHIV and their healthcare workers.
Methods
We used a convergent mixed-methods design, including first year program record review, semi-structured interviews, and a validated Likert scale questionnaire rating illness perception before and after Homecare. Interview data were collected from 15 PLWHIV in Metro Detroit and two healthcare workers responsible for program delivery. Semi-structured interviews focused on obstacles to clinic-based care, support networks, and illness perceptions. Interview data were transcribed and analyzed using a thematic approach. A fully coded analysis was used to create a conceptual framework of factors contributing to Homecare’s success. Means in eight categories of the Brief Illness Perception (IPQ) were compared using paired T-tests.
Results
In the first year of Homecare, 28 of 34 participants (82%) became virally suppressed at least once. The program offered (1) social support and stigma reduction through strong relationships with healthcare workers, (2) removal of physical and resource barriers such as transportation, and (3) positive changes in illness perceptions. PLWHIV worked towards functional coping strategies, including improvements in emotional regulation, acceptance of their diagnosis, and more positive perspectives of control. Brief-IPQ showed significant changes in six domains before and after Homecare.
Conclusion
Homecare offers an innovative system for successfully re-engaging and maintaining lost-to-follow-up PLWHIV in care. These findings have implications for HIV control efforts and could inform the development of future programs for difficult to reach populations.
A comparative analysis of lipoprotein transport proteins – LolA and LolB from Vibro cholerae and LolA from Porphyromonas gingivalis
Authors: Jaiman Deepika , Nagampalli Raghavendra , Persson Karina 
Published: March 2023

Abstract
In Gram-negative bacteria, N-terminal lipidation is a signal for protein trafficking from the inner membrane (IM) to the outer membrane (OM). The IM complex LolCDE extracts lipoproteins from the membrane and moves them to the chaperone LolA. The LolA-lipoprotein complex crosses the periplasm after which the lipoprotein is anchored to the OM. In g-proteobacteria anchoring is assisted by the receptor LolB, while a corresponding protein has not been identified in other phyla. In light of the low sequence similarity between Lol-systems from different phyla and that they may use different Lol components, it is crucial to compare representative proteins from several species.
Here we present a structure-function study of LolA and LolB from two phyla: LolA from Porphyromonas gingivalis(phylum bacteroidota), and LolA and LolB from Vibiro cholerae (phylum proteobacteria). Despite large sequence differences, the LolA structures are very similar, hence structure and function have been conserved throughout evolution. However, an Arg-Pro motif crucial for function in g-proteobacteria has no counterpart in bacteriodota. We also show that LolA from both phyla bind the antibiotic polymyxin B whereas LolB does not. Collectively, these studies will facilitate the development of antibiotics as they provide awareness of both differences and similarities across phyla.

Abstract
Objective To investigate whether the differential expression of neurotransmitters, their receptors, and synthetases is related to the occurrence and progression of gastric cancer.
Methods Gastric cancer tissue samples from 5 patients and 2 adjacent normal tissue samples were collected, the transcriptome detection of relevant molecules was performed, and the results were compared with the whole proteome data of gastric tissue from normal HPA subjects.
Results HPA showed that highly expressed classic neurotransmitters and neuropeptides were not expressed or very low expressed in 5 gastric cancer tissue samples.
Conclusion We believe that the main cause of gastric cancer may be the extremely low expression or no expression of neurotransmitters, neuropeptides and other genes that should be highly expressed in normal gastric tissue, resulting in out-of-control management of gastric tissue cells and then gastric cancer.

Published: March 2023

Abstract
The mechanical properties of ceramic granular γ-alumina, including resistance and stability, were examined using Nano indentation and Nano scratch tests. In so doing, surface morphology, topography, and roughness of the surface of the granular ceramic were evaluated using a scanning electron microscope and atomic force microscopy. Moreover, the elasticity modulus and hardness of granular γ-alumina were estimated using a Nanoindentation method under different loads. It is showed the nanoparticles of this coarse material are about 17 nm on average. Besides, the results demonstrated that the modulus of elasticity and hardness did not follow a particular process when the load increased. In other words, these features increased or decreased within specific ranges. The modulus of elasticity and hardness of granular γ-alumina was obtained equal to 12.6 GPa and 0.433 GPa, respectively. The plasticity index of granular alumina was also examined, and the results showed that it was highly plastic with a plasticity index of 0.83. Nano scratch tests were performed under two different forces to obtain the scratch resistance of granular γ-alumina. The results revealed that the scratch resistance also surged by increasing the indenter force.

Abstract
Intra-species variability in a diet niche, specifically total niche width (TNW), individual niche width (INW), and individual specialization (IS), was studied using an innovative approach without sacrificing the animals. Stable isotopes (δ13C, δ15N) in four body tissues differing in isotopic half-life were analyzed from four freshwater fish species representing different trophic positions. TNW was widest for the apex predator (European catfish) and narrowest for the obligate predator (Northern pike). INW exhibited a polynomial trend for European catfish, Northern pike and Eurasian perch (mesopredator), decreasing with body mass and increasing again after exceeding a certain species-dependent body mass threshold. Thus, for ectotherms, apex predator status is linked rather to its size than to the species. In herbivores (rudd), INW increased with body mass. IS of predators negatively correlated with site trophic state. The trends can be generalized to other species at similar trophic positions in either aquatic or terrestrial systems.

Abstract
An ensemble of metasediments and gneissic rocks, commonly known as the Jutogh Group and Wangtu Gneissic Complex (WGC), respectively, occur as a tectonic window in the Lesser Himachal Himalaya, India. In the Jutogh Group, chlorite-mica schist, garnet-staurolite schist, and sillimanite-schist develop sequentially, near Jhakri thrust in the west to Wangtu in the east. Phase equilibria modelling implies chemically zoned garnet developed at 550°C to 650°C, 0.8 to 1.0 GPa, destabilising low-temperature assemblages. The retrograde segment consists of exhumation and cooling, resulting in a tight clockwise P-T path. The ɛNd[1.8Ga] of the Jutogh group varies between − 0.97 to − 8.14, with depleted-mantle-model ages between 3.07 Ga to 2.28 Ga. A combination of the isotopic composition of the garnet core and its leachates yields an Sm-Nd isochron age of 472 ± 26 Ma. The combination of the isotopic composition of the biotite, garnet rim, and garnet rim leachate fraction provides an isochron of 453 ± 6 Ma. Textural observations and Insitu U-Th-Pbtotal chemical ages indicate that the metasedimentary rocks contain Cambrian monazites. These monazites exhibit an age cluster around ~ 500 Ma. When combined, the results of phase equilibria modeling, Sm-Nd, and Monazite geochronology imply that the Jutogh Group metamorphosed during Cambro-Ordovician period between India and East Asian Cratons (EAC).
Sustainability Accounting for Greenhouse Gas Emissions Measurement using the GREET LCA Model: Practical Review of Automotive ESG Reporting
Authors: Molnár Péter , Suta Alex , Tóth Árpád 
Published: March 2023

Abstract
The production and personal use of passenger vehicles contribute significantly to greenhouse gas (GHG) emissions, making personal transport a major contributor. In response to increasing pressure from regulators and consumers to lower emissions, original equipment manufacturers (OEMs) have introduced alternative powertrains, such as battery electric vehicles (BEVs). To assess the economic and environmental feasibility of BEVs, OEMs conduct various life cycle assessment (LCA) approaches as part of their internal management practices. However, the public presentation of their results is often ambiguous and of unverifiable quality. This study conducts a review of sustainability impact reporting using the GREET model, which is based on the total vehicle lifecycle. The paper provides a summary of the input data requirements for validating emissions from both the fuel and vehicle cycles as part of the proposed model. The availability of the model components was tested against actual public corporate environmental, social and governance (ESG) reporting disclosures of the largest global automotive OEMs, indicating a deficit in the public presentation of essential sustainability information. The implications of the research suggest that LCA models could benefit sustainability accounting by incorporating proper tagging during accounting practices and taking advantage of digital accounting and reporting practices such as the extensible business reporting language (XBRL). By further developing the model, sustainability reporting can benefit from its structure and workflow, thus ensuring improved information validity for stakeholders.

Published: March 2023

Abstract
An environment-friendly lithium complex grease was prepared using pentaerythritol ester as base oil, lithium compound soap as thickener, and Graphite modified by ionic liquid of different chain lengths as a lubricating additive. The dropping point, corrosion of the grease, and volume resistance were tested. MFT-R4000 high-speed reciprocating friction and wear tester was used to measure the tribological properties under current-carrying and non-carrying currents. A scanning electron microscope (SEM) and photoelectron spectroscopy (XPS) were used to observe the surface of the wear scar. The results show that the polyether base oil OSP680 grease has the best degradation ability and the strongest environmental protection ability. The modified nano-Graphite material can improve the wear resistance of the base grease and the conductivity of the base grease. Ionic liquid has a synergistic effect with nano-Graphite.

Abstract

The hydrophobically associating water-soluble polymers (HAWSPs), which possess both surfactant and polymer properties, have been the subject of considerable research. In this study, a novel HAWSP, poly(acrylic acid-alkyl polyoxyethylene acrylate) (P(AA-AAEOn)), was synthesized via aqueous polymerization of acrylic acid andalkyl polyoxyethylene acrylate (AAEOn) with different ethoxy groups. The structure of P(AA-AAEOn) was characterized by Fourier Transform Infrared spectroscopy (FTIR) and Nuclear Magnetic Resonance (NMR). Additionally, its association behavior in solution was evaluated by surface tension, dynamic light scattering, and rheology. The results indicated that P(AA-AAEOn) exhibited excellent surface activity, and its ability to reduce the water surface tension increased with the increase in the proportion of the hydrophobic group. When the concentration reached 0.01%, P(AA-AAEOn) in the solution changed from intramolecular association to intermolecular association. Furthermore, P(AA-AAEOn) also displayed remarkable shear resistance, shear recovery, and viscoelasticity, with a transition from energy elasticity to entropy elasticity in P(AA-AAEOn) molecules between 25℃ and 35℃.
