Published: January 2022

Abstract
Soy protein isolate is a worthy substitute for meat protein. However, its low level of digestibility limits its spread to new market niches. This problem can be solved by enzymatic hydrolysis of soy protein to peptides. Several research teams have already been solving this problem, but their results were obtained under laboratory conditions and do not provide information about the reproducibility of the results on an industrial scale.

In this paper, we have compared the results of laboratory and semi-industrial experiments of enzymatic hydrolysis of protein. Also the kinetics of the reaction under different conditions is shown, and the final product is characterized.
The obtained results of semi-industrial experiments can form the basis of industrial regulations for the production of soy protein hydrolysate as an easily digestible form of dietary protein for athletes and patients with digestive disorders.

Published: January 2022

Abstract
Background: With the implementation of the two-child policy in China, more couples expressed their desire to have a child. We conducted this study to evaluate the incidence and risk factors of infertility in couples intending to have a first child and second child.Methods: Couples who presented to the pre-pregnancy clinical centers were enrolled from 2013 to 2017. Participants were categorized into “first child intention” and “second child intention” groups based on the number of children they already had. Couples were followed up every three months until pregnancy or 12 months. Data regarding the sociodemographic characteristics, history of reproduction and gynecology, history of male disease, and laboratory and imaging examination results were collected. Odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were calculated and adjusted for potential confounding factors.Results: The overall infertility incidence was 16.95% (369/2177). The infertility incidence of “first child intention” and “second child intention” was 19.30% (355/1839) and 4.14% (14/338). The study showed great differences in infertility risk factors between two groups. Risk factors for “first child intention” infertility included advanced age (>35 years), abnormal body mass index (BMI), longer menstrual durations, endometrial polyps, polycystic ovarian syndrome (PCOS), salpingostomy, and history of mycoplasma. However, in “second child intention” group, clinical risk factor was slightly different, such as leiomyoma, higher age (>40 years).Conclusion: The incidence and risk factors of infertility are significantly different between “first child intention” group and “second child intention” group. Early and targeted intervention for couples in different groups at high risk can help reduce infertility and social burden.

Published: January 2022

Abstract
Purpose: This study is about the discursive positioning of intimate partners: A structural-relational approach to intimate partner violence. The study attempts to uncover the story lines of the IPV narratives, the social force of the discursive acts of the narratives, the enacted positions, and the (de) legitimization of rights and duties of the positions of the referents in the narratives. Method: the study adopts the random sampling method in which two IPV narrative were randomly selected from one pseudo named male and female victims. The narratives were in the form of documented transcripts which is in line with Harre and Van lagenhoove (1999) accounting positioning that allows a retrospect study of social actors positioning of this kind. The study also adopted the Halliday’s transitivity process to substantiate the positioning works in the narrative and the mechanism with which these acts are tied to the social structure. Results: The findings of the study revealed that the declarations of the narratives indicates the evaluative and normative underlying judgment on the deontic powers to say and do something in the moral space of intimate partner relations. Conclusion: a socio-constructionist study of this nature reveals the relationship between the narrative referents point of view about actions, point of actions and line of life as regards the moralities of social behaviour in the moral space of intimate partner relationship and how it triggers tendencies for IPV.

Abstract
Perinatal death, of a fetus or newborn, is a devastating event for families. Following nationwide multicentre recruitment, we assessed ‘genomic autopsy’ as an adjunct to standard autopsy for 200 families who experienced perinatal death, and provided a definite or candidate genetic diagnosis in 105 families. From this understudied cohort, half of the (candidate) diagnoses were phenotype expansions or novel disease genes, revealing previously unknown in-utero presentations of existing developmental disorders, and genomic disorders that are likely incompatible with life. Among the definite diagnoses, 43% were recessively or dominantly inherited, posing a 25% or 50% recurrence risk for future pregnancies. Ten families used their diagnosis for preimplantation or prenatal diagnosis of 12 pregnancies, facilitating the delivery of ten healthy newborns and management of two affected pregnancies. We emphasize the clinical importance of genomic investigations of perinatal death, with short turn-around times, enabling accurate counselling and options for families to prevent recurrence.

Abstract
Rhino-orbital cerebral mucormycosis has increased in the recent second wave of post-Covid-19 illness, mainly in tropical countries like India. The burden of diabetes mellitus and rampant use of corticosteroid, environmental factors, post-covid-19 immunological derangement might be contributory factors to the development of extensive outbreak of ROCM. Cerebrospinal fluid rhinorrhea is rarely documented with such fungal infection in literature. This case report described a 45-year diabetic woman in the post-Covid-19 phase,who developed rhino-orbital cerebral mucormycosis, presenting with spontaneous cerebrospinal fluid rhinorrhea.

Published: January 2022

Abstract
Nitrogen and phosphorus budgeting is considered to be a useful tool for policy makers and stakeholders when dealing with nutrient contamination issues. Although a variety of budgeting approaches have been employed in countries affected by this problem, the direct comparison of possible options for the same area is quite limited. The current study offers a detailed insight into the estimations of nutrient loads and their distribution between different sources for a middle-sized agricultural catchment, with the use of two approaches: mass balance method and SWAT modelling. As a result of their comparison, both methods revealed similar contributions of analysed nutrient sources, although the absolute loads were heterogeneous, which stems from drawbacks related to the quality of the monitoring data, the performance of the model and omission of some catchment processes. However, in light of the performed comparison, we suggest a hybrid solution, combining the best features of both approaches.

Abstract
Background
SARS-CoV-2 is a virus that initially appeared in Wuhan, China, at the end of 2019. Since then, the virus has spread until to almost all countries resulting in a global pandemic. Over time, this virus continues to mutate and produce several other variants. In Indonesia, there are multiple variants of SARS-CoV-2 identified, as well as various local variants that are not yet considered to be ‘variants of concern’. Therefore, this investigation is intended to understand the prevalence and epidemiology of the virus, along with detecting the mutations that occur in genes associated with whole-genome-sequences (WGS) isolated in Indonesia.
Result
Analyses were performed to investigate SARS-CoV-2 prevalence in Indonesia using data obtained from GISAID.org. A whole-genome sequencing was performed on the random samples taken from GISAID.org utilizing the BLAST tool from NCBI. The variants identified in Indonesia are Alpha, Beta and Delta variants, as well as local variants B.1.470 and B.1.466.2. As of the end of November, it was found that there are a total of 5.348 cases of the Delta, 78 cases of the Alpha, 22 cases of the Beta, 572 cases of the local variant B.1.470, and 1.833 cases of the local variant B.1.466.2. Other cases include 219 cases of local variant B.1.1.398, 160 cases of local variant B.1.459 and 1.028 cases of the wild type. In total there are 9.260 isolated genomes collected in GISAID that are located in Indonesia. Using BLAST, WGS of Alpha, Delta, Beta, B.1.470 and B.1.466.2 variants isolated in Indonesia was compared with the wild type from Wuhan NC.045512.2. It was found that multiple mutations have occurred in the samples. The mutations identified as are H69del, V70I, N501Y, D614G, A570D, P681H, T716I, S982A, and D1118H in the Alpha variant, T19R, L452R, T478K, D614G, and D950N in the Delta variant, D215G, D614G, A701V, L241-, L242-, K417N in the Beta variant, D614G, L242F, and S12F in the B.1.470 variant and D614G, N439K, and P681R in the B.1.466.2 variant. These mutations had caused alterations in the characteristics of the virus and how it may affect vaccine efficacy.
Conclusions
The results from whole-genome sequencing of variants isolated in Indonesia have found that multiple mutations have occurred in genes of the SARS-CoV-2 Virus and it caused alterations in the characteristics of the virus and may affect vaccine efficacy. It should be noted that classification from the GISAID website may change overtime. The result in this paper is based on the data taken at the end of November.
Substituent Effect on AIE Mechanism of Two Coumarin Derivatives: Uncommon TICT Fluorescence in Aggregation State
Authors: Li Qiao , Zhao Yang , Niu Zhigang , Wang Enju 
Published: January 2022

Abstract
Two coumarin derivatives, 7-diethylamino-3-(4-nitrophenyl)coumarin (DNC) and 7-hydroxy-3-(4-nitrophenyl)coumarin (HNC), were synthesized via Knoevenagel condensation of salicylaldehyde derivatives with 4-nitrophenylacetonitrile and then cyclization reaction. Both of them were characterized by single-crystal X-ray diffraction. The molecules of DNC are stacked via π-π interaction, while the hydrogen bond interactions instead of π-π interaction were observed in the crystal packing of HNC. Both of DNC and HNC showed solvatochromic properties and aggregation-induced emission (AIE) activities, but the AIE characteristics of them were entirely different. HNC exhibited an AIE phenomenon as the result of the restriction of twisted intramolecular charge transfer (TICT), while DNC emited peculiar dual fluorescence which was assigned to the emission based on the inhibition of TICT state formation and the emission from the TICT state respectively.
An Original Approach to Measure Ligand/receptor Binding Affinity in Non-purified Samples
Authors: Rascol Estelle , Dufourquet Anouk , Baccouch Rim , Soule Pierre , Alves Isabel 
Published: January 2022

Abstract
Several biochemical and biophysical methods are available to determine dissociation constants between a biological target and its ligands. Most of them require purification, labelling or surface immobilisation. However, these measurements remain challenging concerning membrane proteins because purification requires their extraction from the native lipid environment using different approaches, a process that may impact receptor conformation and functionality. We have developed a novel experimental procedure to determine binding affinities of a ligand to a membrane protein, the dopamine D2 receptor (D2R), directly from cell membrane fragments, using microscale thermophoresis (MST). Two main challenges had to be overcome: to determine the concentration of dopamine D2R in the crude sample; to find ways to minimize or account for non-specific binding of the ligand to cell fragments. Using MST, we were able to determine the D2R concentration in cell membrane fragments to be about 36.8 ± 2.6 pmol/mg. Then titration curves allowed the determination of a KD about 5.3 ± 1.7 nM, that is very close to the reported value. Important details of the experimental procedure are detailed to allow the transposition of this novel method to various membrane proteins.

Abstract
Background: Coronary artery disease (CAD) detection in asymptomatic patients still remains controversial. The aim of our study was to evaluate the usefulness of ophthalmologic findings as predictors of the presence of CAD when added to cardiovascular classic risk factors (CRF) in patients with acute coronary cardiopathy suspicion. Methods: After clinical stabilization, 96 patients with acute coronary cardiopathy suspicion were selected and divided in two groups: 69 patients with coronary lesions and 27 patients without coronary lesions. Their 192 eyes were subjected to a complete routine ophthalmologic examination. Samples of tear fluid were also collected to be used in the detection of cytokines and inflammatory mediators. Logistic regression models, receiver operating characteristic curves and their area under the curve (AUC) were analysed. Results: Suggestive predictors were choroidal thickness (CT) (OR: 1.02, 95% CI: 1.01-1.03) and tear granulocyte colony-stimulating factor (G-CSF) (OR: 0.97, 95% CI: 0.95-0.99). We obtained an AUC of 0.9646 (95% CI: 0.928-0.999) when CT and tear G-CSF were added as independent variables to the logistic regression model with cardiovascular CRF: sex, age, diabetes, high blood pressure, hypercholesterolemia, smoking habit and obesity. This AUC was significantly higher (p=0.003) than the prediction derived from the same logistic regression model without CT and tear G-CSF (AUC=0.828, 95% CI: 0.729-0.927). Conclusions: CT and tear G-CSF improved the predictive model for CAD when added to cardiovascular CRF in our sample of symptomatic patients. Subsequent studies are needed for validation of these findings in asymptomatic patients.

Abstract
Purpose To rebuild a model of the pelvis and effectively simulate the trajectory of modified sacroiliac screws, we measured the parameters of each screw and screw channel and assessed the safety and feasibility of the parameters in adults.Method and materials One hundred (50 males and 50 females) normal adult pelvic CT (computed tomography) images were randomly selected and imported into Mimics software to rebuild the three-dimensional pelvis model. In these models, each ideal channel of modified screws was simulated, and then we obtained the precise parameters of screws and channels using Mimics and Three-matic software.Results The results of the comparison (right vs. left) showed that there were no significant differences in any of the angles, radius or M1SI parameters (the first modified sacroiliac). However, one parameter (BS) of M2SI (the second modified sacroiliac), two parameters (AP and BS) of M3SI (the third modified sacroiliac), and three parameters (AP、BS、L) of M4SI (the fourth modified sacroiliac) were statistically significant (P < 0.05). The result of comparison (between genders) showed that there were no significant differences in M1SI and M2SI; in contrast, the radius, length and the α angle of M3SI and M4SI were significantly different between genders (P < 0.05), and the radius of M4SI required special attention. If the radius of the limiting screw channel was >3.50 mm, 52 cases (52%, 24 males and 28 females) could not complete the M4SI screw placement among 100 samples. If the radius of the limiting screw channel was >3.0 mm, a total of 10 cases (10%, 2 males and 8 females) could not complete the M4SI screw placement.Conclusion Through the measurement of 100 healthy adult real three-dimensional pelvic models, we obtained the parameters of each modified sacroiliac screw and measured the three angles of each screw based on international coordinates for the first time, which can instruct clinical application.

Abstract
Background

Modern studies have shown that chrysanthemum has anti-inflammatory, regulating intestinal function and other effects, chrysanthemum stem and leaf as a nonmedicinal part of chrysanthemum, has similar chemical components with

chrysanthemum, so it is speculated that chrysanthemum stem and leaf also has the effect of regulating intestinal inflammation. The purpose of this study was to evaluate the antiinflammatory and antioxidant effect of chrysanthemum stem and leaf extract through zebrafish inflammatory bowel disease model, and to detect flavonoids, phenolic acids and polysaccharides in chrysanthemum stem and leaf extract.

Methods

DSS induced inflammatory bowel disease model of zebrafish was used.

Aliciin blue staining was used to observe the secretion of intestinal acid mucin, and H&E staining was used to detect the inflammatory cell infiltration. Superoxide dismutase activity was determined by kit, and the expression levels of key inflammatory cytokines IL-1 β , IL8 and MMP9 were detected by quantitative polymerase chain reaction. Furthermore, UPLC-TQ /MS method was used to detect the contents of flavonoids and phenolic acids in chrysanthemum stem and leaf extracts. Neutral and acidic polysaccharides were determined by the phenol-sulfuric acid method and the carbazol-sulfuric acid method.

Results

H&E staining showed that extracts from chrysanthemum stem and leaf inhibited inflammatory cell infiltration to varying degrees. The expressions of inflammatory cytokines IL-1 β , IL8 and MMP9 were significantly increased in DSS induced zebrafish. The extracts inhibited the expression of IL-1 β , IL8 and MMP9 in DSS induced zebrafish. The water extract 0.2mg/ mL and alcohol extract 0.04mg/ mL had the most significant inhibition. Superoxide dismutase activity in extract treatment group was also up-regulated compared with model group. The results showed that the contents of total flavonoids and phenolic acids in the alcohol extract of chrysanthemum stem and leaf were significantly higher than those in the water extract of chrysanthemum stem and leaf, but the water-soluble polysaccharides were significantly more in the water extract of chrysanthemum stem and leaf.

Conclusions

In conclusion, this study suggests that chrysanthemum stem and leaf extract can improve inflammatory bowel disease of zebrafish through antiinflammatory and antioxidant activities.

Published: January 2022

Abstract
PURPOSE: This study investigated the impact of bicuspid aortic valve (BAV) on valve morphology and motion as well as proximal and aortic hemodynamics using a same-day echocardiography and cardiac MRI. METHODS: Transthoracic echocardiography, two-dimensional cine MRI of the aortic valve, and aortic 4D flow MRI were performed on the same day in 9 normofunctional BAV patients (age=41±12, 3 female), 4 BAV with moderate to severe aortic stenosis (AS) (age=63±5, 1 female), and 36 healthy tricuspid aortic valve controls (age=52±10, 21 female). Valve opening and closing timings and transvalvular peak velocity were measured using B-mode and Doppler echocardiogram, respectively. Valve orifice morphology at fully-opened state was characterized using cine MRI. Ascending aortic (AAo) wall shear stress (WSS) was measured using 4D flow MRI data. RESULTS: Valve motion timings were similar between BAV and controls. BAV was associated with increased orifice aspect ratio (1.44±0.11 vs. 1.10±0.13, P<0.001), transvalvular peak velocity (1.5±0.3 vs. 1.2±0.2 m/s, P<0.001) and maximum AAo WSS (1.62±0.31 vs. 0.91±0.24 Pa, P<0.001). Increased orifice aspect ratio was associated with the increase in transvalvular peak velocity (r=0.80, P < 0.0001) and maximum AAo WSS (r=0.83, P<0.0001). Transvalvular peak velocity was also positively correlated with maximum AAo WSS (r=0.83, P<0.0001). CONCLUSION: A same-day echo and MRI imaging allows for comprehensive assessment of the impact of aortic valve disease on valve function and hemodynamics. In this pilot application to BAV, we found increased orifice aspect ratio may be responsible for increased transvalvular peak velocity and maximum AAo WSS.
