Objective
To explore the predictive value of the abdominal wall scar score for pelvic floor function rehabilitation, vaginal microecology and complications after cesarean section.

Methods
A total of 120 pregnant women who underwent cesarean section in our hospital from January to December 2022 were selected. The patients were divided into observation group (score ≥ 60, n = 52) and control group (score < 60, n = 68) according to the preoperative score of abdominal wall scar and whether the score exceeded 60. The pelvic floor function rehabilitation, vaginal microecology and complications were compared between the two groups, and the score of abdominal wall scar was evaluated by receiver operating characteristic (ROC) curve. The predictive value of pelvic floor function rehabilitation, vaginal microecology and complications after cesarean section was evaluated.

Results
There were significant differences between the two groups in postpartum class I and class II muscle fiber strength and pelvic floor muscle potential (P < 0.05). ROC curve showed that the AUC of abdominal scar score in predicting pelvic floor function rehabilitation was 0.806 (95% CI [0.684–0.927]), the specificity was 80.17%, and the sensitivity was 79.76%. There was significant difference in the abnormal rate of leukocte estrase (LE) and Acetylaminoglucosidase (NAG) between the two groups (P < 0.05). ROC curve showed that the AUC of abdominal scar score in predicting vaginal microecology was 0.871 (95% CI [0.776–0.966]), the specificity was 85.09%, and the sensitivity was 82.36%. There was significant difference in the incidence of postpartum complications between the two groups (P < 0.05). ROC curve showed that the AUC of abdominal scar score in predicting complications was 0.844 (95% CI [0.735–0.953]), the specificity was 82.27%, and the sensitivity was 81.15%.

Conclusion
The abdominal scar score has a certain effect on predicting the recovery of pelvic floor function, vaginal microecology and complications after cesarean section. Therefore, it can help the medical staff to adjust the treatment measures in time, which can be used as a means of preoperative auxiliary examination.
Simulation of hearing loss can induce pitch shifts for complex tones
Authors: Ichimiya Issei , Ichimiya Hiroko 
Published: September 2023

Background
Most studies on pitch shift provoked by hearing loss have been conducted using pure tones. However, many sounds encountered in everyday life are harmonic complex tones. In the present study, psychoacoustic experiments using complex tones were performed on healthy participants, and the possible mechanisms that cause pitch shift due to hearing loss are discussed.

Methods
Two experiments were performed in this study. In experiment 1, two tones were presented, and the participants were asked to select the tone that was higher in pitch. Partials with frequencies less than 250, 500, 750, or 1,000 Hz were eliminated from the harmonic complex tones and used as test tones to simulate low-tone hearing loss. Each tone pair was constructed such that the tone with a lower fundamental frequency (F0) was higher in terms of the frequency of the lowest partial. Furthermore, partials whose frequencies were greater than 1,300 or 1,600 Hz were also eliminated from these test tones to simulate high-tone hearing loss or modified sounds that patients may hear in everyday life. When a tone with a lower F0 was perceived as higher in pitch, it was considered a pitch shift from the expected tone. In experiment 2, tonal sequences were constructed to create a passage of the song “Lightly Row.” Similar to experiment 1, partials of harmonic complex tones were eliminated from the tones. After listening to these tonal sequences, the participants were asked if the sequences sounded correct based on the melody or off-key.

Results
The results showed that pitch shifts and the melody sound off-key when lower partials are eliminated from complex tones, especially when a greater number of high-frequency components are eliminated.

Conclusion
Considering that these experiments were performed on healthy participants, the results suggest that the pitch shifts from the expected tone when patients with hearing loss hear certain complex tones, regardless of the underlying etiology of the hearing loss.

Published: September 2023

The study is based on secondary data which tests the price movement and integration between major national wheat markets i.e. Lakhimpur, Agra, Vidisha, Dewas, Kota and Baran markets. Monthly wheat prices data of 15 years from 2007-08 to 2021-22 which was collected from www.agmarknet.gov.in. To analyze the market integration among major wheat markets, the Augmented Dickey-Fuller test, Johansen Co-integration test and Granger Causality test were applied with the help of E-views statistical package. The results indicated the strong market integration in terms of price linkages among major wheat markets. The results revealed that the major markets of wheat have strong price linkages and thus are spatially integrated. It could be seen that existence of mostly (10) unidirectional causality with few (3) bidirectional causality among selected wheat markets. It was further revealed from the analysis that, any disturbance in price will get corrected in about 5 days in Lakhimpur market, 3 days in Agra market and 3 days in Kota market in short-run equilibrium. The transfer of price signals from one market to another helps in stabilizing the prices over space and create a healthy competitive environment. This would also help to protect the interest of producer-sellers. In order to achieve the goal of integration, the government should strengthen the market intelligence and communication within markets. The following study recommendations were made: a) Government should subsidize provide is transportation. b) Government and stakeholder should advise commercial banks to give low interest long-term loans to farmers because many impoverished farmers can't afford crop mechanization. c) Government and other i.e, NGO advertising should be increased to raise knowledge about improved agricultural machinery. d) Government and other i.e, NGO should educate farmers. Farmers can employ technology if they are trained and educated. They should also be told how much fertilizer to use so it yields more.

A field experiment was conducted on experimental farm of Dept. of Agricultural Meteorology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, Maharasthra, India during the during kharif season 2015 under rainfed condition to find the relationship of pheno thermal and heat use efficiency indices with yield. The field experiment was laid out in factorial randomized bock design with five sowing dates (i.e. 25th, 26th, 27th, 28th and 29th SMW) and three varieties (viz., BDN-711, BSMR-736 and BSMR-853) with three replications. The sowing dates significantly influenced on the phenology, growth, development and yield attributes. The dry spell experienced during sowing to emergence period in first sowing date (25th SMW sowing) and thereafter no rainfall condition during remaining period of sowings viz., 26th, 27th, 28th and 29th SMW, therefore, emergence and final plant count was observed lowest in 25th SMW (30 and 29 %) and highest in 27th SMW sowing (92 %). Hence, significantly highest dry matter plant-1, no. of pods plant-1, seed weight and seed yield plant-1 was observed in 25th SMW sowing; seed yield (417.7 kg ha-1), seed yield heat use efficiency (0.20 kg ha-1 0C day-1) was recorded highest in 27th SMW sowing and lowest in 25th SMW sowing. Significantly highest no. of pods plant-1, seed weight and seed yield plant-1, seed yield heat use efficiency, pheno thermal index was observed in BDN-711 variety and significantly lowest in BSMR-853 variety. The significantly highest total dry matter plant-1 was observed in BSMR-853 and lowest in BDN-711 variety. Significantly highest GDD, HTU and PTU required for completion of different phenophases were recorded in BSMR-736 variety and significantly lowest in BDN-711 variety. Weather indices viz., GDD, HTU, PTU, PTI showed non-significant correlation at all the phenophases with seed yield of pigeonpea. The yield prediction model based on thermal indices and seed yield heat use efficiency at floral bud initiation to 50 % flowering and at 50 % flowering to 50 % pod formation phenophases was found useful in assessing the crop yield one and half to one month in advance.

ImportanceDigital technology represents an opportunity to improve outcomes following total knee replacement (TKR). Digitally delivered interventions have been shown to be similar to face-to-face interventions and to increase participation levels in people with osteoarthritis.ObjectiveTo assess the effect of a digital technology package in reducing pain compared with usual care following TKR.Design, Setting, and ParticipantsThis randomized clinical trial recruited 102 adults after they received TKR in 3 rehabilitation hospitals in Sydney, Australia, between June 2020 and July 2021.InterventionsAll participants underwent usual care. In addition to usual care, 51 participants received a digital technology package consisting of an exercise app, fitness tracker, and online health coaching. In the usual care group, 51 participants received a fitness tracker but with all notifications turned off and goals for step count, sleep, and active hours removed. Participants were followed up for 12 months (June 2021 to July 2022).Main Outcome and MeasuresThe primary outcome was mean knee pain during the past week assessed using a numerical rating scale (range, 0-10, with 10 indicating worst possible pain) at 3 months. In unadjusted analyses, considered primary and based on multiple imputations, independent t tests were used to compare means between groups. Secondary outcomes, including measures of function, activity participation, and quality of life, were analyzed using a generalized estimating equation model that accounted for repeated measurements.ResultsOf 102 participants (mean [SD] age, 67.9 [7.2] years; 68 [67%] female; and 92 [90%] White) randomly assigned to intervention or usual care groups, 47 (92%) in each group completed the 3-month follow up. At 3 months, participants in the intervention group demonstrated small but not clinically meaningful improvements in pain compared with the usual care group in the unadjusted intention-to-treat analysis (mean difference, −0.84; 95% CI, −1.59 to −0.10; P = .03). Secondary outcomes indicated a statistically significant reduction in pain intensity, (mean difference, −0.94; 95% CI, −1.82 to −0.06), pain disability (mean difference, −5.42; 95% CI, −10.00 to −0.83), and sedentary behavior (mean difference, −9.76; 95% CI, −19.17 to −0.34) favoring the intervention from baseline to 3, 6, and 12 months.Conclusions and RelevanceIn this randomized clinical trial, a combined digital technology program provided small but not clinically meaningful improvements in pain at 3 months and other longer-term favorable outcomes following TKR compared with usual care. Future studies should tailor digital interventions based on participants’ abilities and preferences to ensure that the intervention is appropriate and fosters long-term self-management.Trial RegistrationAnzctr.org.au Identifier: ACTRN12618001448235

AbstractFerroptosis featured by iron‐dependent lipid peroxidation plays a critical role in tumor regression, offering an alternative therapeutic target for the treatment of aggressive triple‐negative breast cancer. However, the traditional delivery strategy to enrich iron deposition is limited in producing a surplus of lipid oxidation because of the aggressive antioxidant response established in solid tumors. Here, vitamin B2‐ferric chloride nanocomplex self‐assembled through the coordination of ferric iron and hydroxy groups to simultaneously promote iron accumulation and oxidative stress is employed. It is observed that the self‐assembly nanostructures with appropriate size enable effective delivery of the therapeutic agents to the tumor site and cancer cells. More importantly, sonosensitizer vitamin B2 and ferric chloride cooperatively facilitate the production of reactive oxygen species and amplify nanocatalytic therapy. To further disrupt the antioxidant system, metformin with solute carrier family 7 member 11 inhibitory activity is used to synergistically boost ferroptosis of tumor cells. The combinational ferroptosis promoter exhibits augmented nanocatalytic antitumor efficacy in 4T1 tumor‐bearing mice with negligible adverse effects. Taken together, this study may provide a novel paradigm of self‐assembled vitamin B2‐ferric nanocomplex for ferroptosis regulation.

AbstractDevices with volatile memristive switching and self‐sustained relaxation oscillations have received significant attention for their use in neuromorphic computing and solving optimization problems. However, obtaining devices with stable response and reliable oscillation remains challenging. This work describes the utility of metal/oxide interlayers in achieving reliable device performance with tuneable characteristics using Nb‐Nb2O5‐Pt structures. Detailed physical characterization of the Nb/Nb2O5 interlayer region shows that it consists of a thin, near‐stoichiometric Nb2O5 and an NbOx layer with a graded oxygen content. The impact of these interlayers on device performance is assessed by investigating their switching characteristics and oscillation dynamics. It is shown that the presence of the interlayer has a direct impact on the memristive switching mode and parameters threshold switching characteristics parameters. These dependencies are explained with reference to a lumped‐element circuit model of the device and shown to be dominated by changes in device resistance caused by interlayer formation. Significantly, stable oscillation with tuneable frequency is obtained by increasing the thickness of the reactive Nb electrode. Then, by simulating an array of coupled oscillators, a unique Hamiltonian solver is demonstrated. These results provide pathways for optimizing volatile memristive switching characteristics and guidance on how such devices can be employed to solve combinatorial optimization problems.

AbstractPolymeric materials have been widely researched and used as active‐layers to fabricate data‐storage resistance random‐access memory (ReRAM) devices. Nevertheless, the problems as drift voltage, weak stability, and low reproducibility largely restrict their practical application in next‐generation memory systems, mainly induced by the molecular stacking defects that limited the efficient charge‐carrier migration throughout the active‐layers. Thus, how to weaken the molecular stacking defects and thus improve the overall ReRAM performance is a scientific issue that needs to be solved urgently. In this work, an organometallic polymer 5,12‐di(thiophen‐2‐l)‐2,9‐di(tridecan‐7‐yl)anthra[2,1,9‐def:6,5,10‐d'e'f']diisoquinoline‐1,3,8,10(2H,9H)‐tetraone P(DTPDI‐Fc) is designed with ferrocene (Fc) and perylenediimide (PDI) building repeats. The X‐ray diffraction (XRD) test confirms the regioregular stacking styles of P(DTPDI‐Fc) in solid states, and atomic force microscope (AFM) measurement verified the continuous and smooth surface morphology of P(DTPDI‐Fc) films. Therefore, the charge carriers can easily inject into P(DTPDI‐Fc) film and can efficiently migrate throughout P(DTPDI‐Fc) films. Thus, P(DTPDI‐Fc) devices show excellent memory behaviors with low high‐conductance state ON‐state current, stable threshold voltage, long‐time stability, and high device reproducibility. This work affords a practical strategy to weaken molecular stacking defects and to improve stacking regioregularity, which will give a guidance for the designing of multilevel data‐storage ReRAM devices in future researches.

AbstractMethicillin‐resistant Staphylococcus aureus (MRSA) is threatening human health due to its resistance to multiple antibiotics. Excessive copper (Cu) ions target the lipoylated proteins of tricarboxylic acid cycle of cancer cells, inducing proteotoxic stress and their cuproptosis death. Whether cuproptosis plays a part in killing MRSA by low‐dose supplement of Cu ions remains to be explored. Herein, Cu‐doped hydroxyapatite nanorods (PC) are prepared on polyetheretherketone (PEEK) to resist infection and improve PEEK performance in tissue integration with the assistance of near‐infrared (NIR) irradiation, and the mechanism against MRSA is elucidated. Mild photothermal stimulation increases bacterial membrane permeability, accelerating Cu ions’ intake and consequently inducing cuproptosis‐like death of MRSA. It is confirmed by aggregation of dihydrolipoamide S‐acetyltrans‐ferase (DLAT), deactivation of glutathione peroxides 4 (GPX4), and destabilization of Fe─S cluster proteins ferredoxin (FDX1) and lipoyl synthase (LIAS). Fortunately, fibroblast behaviors are upregulated on NIR‐irradiated PC. In vivo, PC with NIR irradiation exhibits outstanding MRSA elimination, reduced inflammation response, and improved biointegration. Overall, it is demonstrated that bacterial cuproptosis‐like death can be induced by Cu ions at a non‐cytotoxic dose when cooperated with mild heat stimulus, and this photothermal strategy of PC has greatly promising application in improving PEEK performance in clinic.

AbstractOrganic photoluminescent materials exhibiting room‐temperature phosphorescence (RTP) have attracted widespread attention. However, most of them can emit phosphorescence only in the solid state, which strongly limits their applications. Herein, a type of phosphorescent hydrogel with excellent mechanical properties is prepared by immersing an as‐prepared poly(vinyl alcohol) (PVA) hydrogel in a poly(sodium maleate) solution and then in a CaCl2 solution, followed by drying under stretching at 90 °C and finally soaking it in deionized water until equilibrium swelling to produce poly(vinyl alcohol)/poly(calcium maleate)‐DS ( PVA/PMACa‐DS) hydrogels. Such hydrogels exhibit excellent mechanical properties, showing tensile strengths up to 15 MPa, due to the presence of strong hydrogen bonding and especially ionic bonding. The PVA/PMACa‐DS hydrogels emit varied phosphorescence emission colors from blue to yellow‐green upon excitation with 312–400 nm light, with a maximum lifetime of 13.4 ms. Experiments and theoretical calculations demonstrate that ionic crosslinking between Ca2+ and nonconventional chromophores prevents the contact of the nonconventional chromophores with water molecules and hence restricts nonradiative decay, leading to RTP emission. This work provides a reliable strategy for designing RTP hydrogels with excellent mechanical properties based on nonaromatic polymers for emerging applications.
