Background The dairy cow’s postpartum period is characterized by dramatic physiological changes,therefore imposing severe challenges on the animal for maintaining health and milk output.The dynamics of the ruminal microbiota are also tremendous and may play a crucial role in lactation launch.We aim to investigate the potential benefits of early microbial intervention by fresh rumen microbiota transplantation(RMT)and sterile RMT in postpartum dairy cows.Twelve fistulated peak-lactation dairy cows were selected to be the donors for rumen fluid collection.Thirty postpartum cows were divided into 3 groups as the transplantation receptors respectively receiving 10 L fresh rumen fluid(FR),10 L sterile rumen fluid(SR),or 10 L saline(CON)during 3 d after calving.Results Production performance,plasma indices,plasma lipidome,ruminal microbiome,and liver transcriptome were recorded.After fresh and sterile RMT,we found that the molar proportion of propionic acid was increased on d 7 in the FR and SR groups and the bacterial composition was also significantly changed when compared with the CON group.A similarity analysis showed that the similarities between the CON group and FR or SR group on d 7 were 48.40%or 47.85%,whereas the similarities between microbiota on d 7 and 21 in the FR and SR groups were 68.34%or 66.85%.Dry matter intake and feed efficiency were not affected by treatments.Plasmaβ-hydroxybutyrate concentration in the FR group was decreased and significantly different lipids mainly included phosphatidylcholine and lysophosphatidylcholine containing polyunsaturated fatty acids.Hepatic transcriptomics analysis indicated acutephase response pathways were upregulated in the SR group.Conclusions Our study suggests that RMT can shorten the transition process of the ruminal microbiota of postpartum dairy cows with no benefit on dry matter intake or feed efficiency.Inoculation with rumen fluid may not be a useful approach to promote the recovery of postpartum dairy cows.

Chinese Journal of Plastic and Reconstructive Surgery 2024年第1期6卷 1-7页

作者： Zhaohua Jiang Ziyou Yu Shengli Li Shanghai Jiao Tong University Shanghai Ninth People’s Hospital Department of Plastic and Reconstructive Surgery

Background: Lymphedema is a debilitating condition that frequently occurs after breast cancer treatment. Vascularized lymph node transfer(VLNT) is a promising approach to reduce lymphedema. This study used magnetic resonance lymphangiography(MRL) to assess lymphatic reconnections post-VLNT in patients with breast cancerrelated lymphedema(BCRL).Methods: The clinical records of six female patients with unilateral upper limb BCRL who underwent VLNT(4cases) or VLNT combined with breast reconstruction(2 cases) were retrospectively reviewed. All patients were examined using MRL preoperatively and at the 1-year follow-up. The morphological characteristics of the lymphatic network, dermal backflow patterns, and architecture of the lymph nodes were evaluated. Clinical outcomes, patient satisfaction, and complications were assessed.Results: At the 1-year follow-up, reduction in tissue edema and limb circumference was achieved in all six patients.In MRL, the implanted lymph nodes in the axillary region of the affected upper arm were enhanced and visualized in all six patients. Reconnected lymphatic vessels in the subcutaneous tissue associated with the implanted lymph nodes were observed in four patients. Decreased dermal backflow and lymphatic vessel dilation of the affected limbs were observed in all six patients. No disruption of the lymph flow in the donor area was detected.Conclusion: This is the first study to provide direct imaging evidence for the reconnection of afferent lymphatic channels between implanted lymph nodes and the recipient lymphatic system in patients with BCRL. Overall, our study demonstrates the mechanism and efficacy of VLNT in reducing lymphedema.

The wide applications of Generative adversarial networks benefit from the successful training methods,guaranteeing that an object function converges to the local minimum.Nevertheless,designing an efficient and competitive training method is still a challenging task due to the cyclic behaviors of some gradient-based ways and the expensive computational cost of acquiring the Hessian matrix.To address this problem,we proposed the Adaptive Composite Gradients(ACG)method,linearly convergent in bilinear games under suitable settings.Theory analysis and toy-function experiments both suggest that our approach alleviates the cyclic behaviors and converges faster than recently proposed SOTA algorithms.The convergence speed of the ACG is improved by 33%than other methods.Our ACG method is a novel Semi-Gradient-Free algorithm that can reduce the computational cost of gradient and Hessian by utilizing the predictive information in future iterations.The mixture of Gaussians experiments and real-world digital image generative experiments show that our ACG method outperforms several existing technologies,illustrating the superiority and efficacy of our method.

This study was to investigate growth performance, rumination development, rumen fermentation and feed digestion in young calves provided high volumes(about 20% of calf birth weight) of milk with or without forage inclusion and how these parameters correlate with each other. Immediately after birth,160 newborn Holstein female calves(41.6 ± 4.2 kg of initial BW) were randomly divided into 2 treatments: 1) starter(CON, only starter) and 2) starter and hay(HAY, both starter and hay). The calves were fed their respective experimental diets from d 4 to 84, after which they were all introduced to similar diets until the end of the experiment on d 196. Treatment had no effect on growth and structural measurements throughout the experimental period. However, treatment had an effect on the other parameters, mainly during the post-weaning period. Forage supplementation tended to reduce starter dry matter intake(P = 0.05), while increasing the forage intake(P lity of dry matter(DM), NDF and ether extract(EE), but lower digestibility of organic matter(OM, P = 0.03), crude protein(CP, P lity or between rumination time per kilogram DM and nutrient digestibility. In conclusion, feeding hay to calves fed a high milk level improved rumination during the post-weaning period only, without a concomitant effect on

Resonant beam communications (RBCom), which adopts oscillating photons between two separate retroreflectors for information transmission, exhibits potential advantages over other types of wireless optical communications (WOC). However, echo interference generated by the modulated beam reflected from the receiver affects the transmission of the desired information. To tackle this challenge, a synchronization-based point-to-point RBCom system is proposed to eliminate the echo interference, and the design for the transmitter and receiver is discussed. Subsequently,the performance of the proposed RBCom is evaluated and compared with that of visible light communications(VLC)and free space optical communications (FOC). Finally, future research directions are outlined and several implementation challenges of RBCom systems are highlighted.

Photocatalysis has been a research hotspot in recent years,and the design and modification of photocat-alysts have been the key points.Common methods for designing photocatalysts,including constructing heterojunctions and homojunctions,have been developed on the basis of heterojunctions.In this study,two homojunctions of manganese dioxide(MnO_(2)),including a high-index crystal plane homojunction and a general homojunction,are prepared using a stepwise hydrothermal method.Using a capping agent,the high-index crystal surface of the MnO_(2)is exposed.It is found that the electron transport efficiency be-tween the two components of the homojunction with high-index planes is higher and the adsorption capacity of the oxygen is stronger,which leads to higher photocatalytic efficiency.In addition,the newly designed high-index homojunction is used for the treatment of bacterial infections,and it kills Staphy-lococcus aureus(S.aureus)and Escherichia coli(E.coli)at rates of 99.95%±0.04%and 99.31%±0.25%,respectively.It also has excellent therapeutic effects on mouse wounds,which implies superb practical application value.This work provides a new strategy for the improved design of homojunctions and the application of photocatalytic materials.

The fruits of Amomum tsao-ko(Cao-Guo)were documented in Chinese Pharmacopoeia for the treatment of abdominal pain,vomiting,and plague.In our previous study,a series of diarylheptanes and flavonoids withα-glucosidase and protein tyrosine phosphatase 1B(PTP1B)inhibitory activity have been reported from the middle-polarity part of A.tsao-ko,whereas the antidiabetic potency of the low-polarity constituents is still unclear.In this study,three new hydroxytetradecenals,(2E,4E,8Z,11Z)-6R-hydroxytetradeca-2,4,8,11-tetraenal(1),(2E,4E,8Z)-6R-hydroxytetradeca-2,4,8-trienal(2)and(2E,4E)-6R-hydroxytetradeca-2,4-dienal(3)were obtained from the volatile oils of A.tsao-ko.The structures of compounds 1–3 were determined using spectroscopic data involving 1D and 2D nuclear magnetic resonance(NMR),high-resolution mass spectra(HRMS),and specific rotation([α]D).Their hypoglycemic activity was evaluated against glycogen phosphorylase(GPa)and PTP1B.Compounds 1 and 2 displayed moderate activity against PTP1B with inhibition rates of 33.8%−50.3%at 100 and 200μM.Moreover,compound 1 exhibited an obvious inhibitory effect on GPa(IC50=31.7μM),whereas compound 2 was inactive.This study demonstrates hydroxytetradecenals as the characteristic components of A.tsao-ko with therapeutic potential in diabetes.

The yellow seed trait is preferred by breeders for its potential to improve the seed quality and commercial value of Brassica napus.In the present study,we produced yellow seed mutants using a CRISPR/Cas9 system when the two BnPAP2 homologs were knocked out.Histochemical staining of the seed coat demonstrated that proanthocyanidin accumulation was significantly reduced in the pap2 double mutants and decreased specifically in the endothelial and palisade layer cells of the seed coat.Transcriptomic and metabolite profiling analysis suggested that disruption of the BnPAP2 genes could reduce the expression of structural and regulated genes in the phenylpropanoid and flavonoid biosynthetic pathways.The broad suppression of these genes might hinder proanthocyanidin accumulation during seed development,and thereby causing the yellow seed trait in B.napus.These results indicate that BnPAP2 might play a vital role in the regulatory network controlling proanthocyanidin accumulation.

A review of the literature in commonly used retrieval systems generally yields minimal or no pertinent information on the early works of Chinese doctors.Herein,the early works in rhinoplasty by pioneers Dr.Maolian Hu(胡懋廉)and Dr.PC Nyi(倪葆春)were retrieved from the database of Chinese Medical Journal published before1949 that overseas doctors could not gain access to online possibly due to the language barrier in collecting and processing those old professional data by main retrieval systyems.They published original articles on costal cartilage applications for correction of saddle noses in as early as 1939 and 1949,respectively,which represent the earliest attempts of treating nasal deformities with costal cartilages in China as well as in Asia.The private cosmetic surgical practices in rhinoplasty from the 1930s to the 1940s were recovered and briefly reviewed,and some of the most important clinical cases were presented.Other important events related to rhinoplasty,such as the establishment of the first national society of rhinoplasty in Chengdu,China in 2011 and the successful performance of the first national congress on rhinoplasty in Shanghai,China in 2012,were included.
