Protein kinase D1 promotes the survival of random-pattern skin flaps in rats.

BACKGROUND: In reconstructive surgery, random skin flaps are commonly used tools to cover skin defects, however, their applicability and size are limited by post-operative complications such as marginal ischemia-reperfusion injury and flap necrosis. Protein kinase D1 (PKD1), a calcium/calmodulin-dependent serine/threonine kinase, is known to induce angiogenesis and has been shown to mitigate ischemia in cardiovascular diseases. However, the role of PKD1 has not been investigated in skin flaps. METHOD: Seventy-five male Sprague-Dawley rats with skin flaps were randomly divided into three groups: control, PKD1, and CID755673. Seven days following surgery, we assessed the general view and survival rate of the flap using histological analysis. Laser Doppler and lead oxide/gelatin angiography were used to evaluate microcirculation blood flow. Histopathological changes, neovascularization and microvascular density (MVD). were examined and calculated using microscopy after H&E staining. Protein expression levels were determined using immunoblotting and immunohistochemistry techniques. RESULT: PKD1 significantly improved flap survival by upregulating angiogenic factors VEGF and cadherin5 and increasing antioxidant enzymes SOD, eNOS, and HO1, as well as reducing caspase 3, cytochrome c, and Bax expression, and attenuating IL-1ß, IL-6, and TNF-α. In the PKD1 group, PKD1 increased neovascularization, and blood flow and flap survival areas were larger as compared to the control and CID755673 groups. CONCLUSION: These findings show that PKD1 accelerates angiogenesis, reduces oxidative stress, and impedes apoptosis and inflammation, thus resulting in improved flap survival. Our observations indicated that PKD1 could be a therapeutic target for flap failure treatment.

Microbial network and composition changes according to tobacco varieties and interferes differently in black shank disease defense.

AIMS: The soil-borne oomycete pathogen Phytophthora parasitica can cause black shank disease in tobacco plants. The use of resistant varieties can be used to control black shank disease. The potential relationships of the composition of the rhizosphere microbiome to resistance to black shank disease are poorly understood. This work aims to compare the rhizosphere microbial community and network of the tobacco resistant variety HB202 with the susceptible variety XY3. METHODS AND RESULTS: Rhizospheric soils were collected from tobacco plants of HB202 and XY3 in the fields with same soil types and agricultural operations. The compositions of the rhizosphere microbial communities were revealed by Illumina sequencing of bacterial 16S rRNA genes and fungal spacer (ITS) sequences and analysed with molecular ecological network pipeline. The alpha diversity of fungal communities of the two varieties was significantly different. The structure and composition of bacterial and fungal communities in the resistant variety in the rhizosphere was different from the susceptible variety. Relative abundances of beneficial genera in the HB202 microbiota were higher than in the XY3. Conversely, the XY3 microbiota exhibited a higher abundance of deleterious genera compared to the HB202 microbiota. The resistant variety influences the topological properties and microbial interactions in the rhizosphere against the disease. The network of the HB202 was more complex and had higher connectivity compared to the XY3 network. CONCLUSIONS: The rhizosphere microbial communities and networks of two tobacco varieties are very different. These changes in the microbial communities and their interactions may play an important role in tobacco resistance to black shank disease.

The addition amount of the strains ranged from 1×10~6 to 6×10~7 CFU/g, the median value was 1×10~6 CFU/g. CONCLUSION: There is insufficient scientific evidence on the feeding effect, types and amounts of microbial food cultures added to infant and follow-up formula in China.

[Distribution of vitamin K_2 content in Chinese traditional fermented soybean products].

OBJECTIVE: To determine the content of vitamin K_2 in different types of fermented bean products and analyze the difference of vitamin K_(2 )content. METHODS: A total of 98 kinds of typical fermented bean products were included in Chinese traditional fermented bean products(Douchi, Sufu, soybean paste). Process, region, sales volume, raw materials and flavor were considered, and the content of vitamin K_2 in fermented bean products was determined by high performance liquid chromatography. RESULTS: Chinese bean fermented foods generally contained vitamin K_2, and the subtype menaquinone-7(MK-7)was the main one. The content of vitamin K_2 in Douchi was the highest(437.55 µg/100 g), the content of vitamin K_2 in Sufu and Soybean paste were lower(7.48 µg/100 g and 2.47 µg/100 g). The content of vitamin K_2 in bacterial Douchi was higher than that in Mucor type and Aspergillus oryzae type which were 403.94, 232.98 and 81.00 µg/100 g(P<0.05). Soybean type Douchi was higher than that in black bean type of Douchi which were 610.41, 178.08 µg/100 g(P<0.05), and the content of vitamin K_2 in dry Douchi was higher than the content of vitamin K_2 in water Douchi which were 1 517.45 µg/100 g, 297.58 µg/100 g(P<0.05). However, there were no significant difference in the content of vitamin K_2 in Soybean paste and Sufu in different types and regions(P > 0.05). CONCLUSION: Vitamin K_2 is widely contained in Chinese fermented bean products, and its content is mainly affected by fermentation microorganisms and processing technology.

Sparstolonin B suppresses free fatty acid palmitate-induced chondrocyte inflammation and mitigates post-traumatic arthritis in obese mice.

Abnormal lipid metabolism, such as systemic increased free fatty acid, results in overproduction of pro-inflammatory enzymes and cytokines, which is crucial in the development of obesity-related osteoarthritis (OA). However, there are only a few drugs that target the lipotoxicity of OA. Recent researches have documented that the traditional Chinese medicine, Sparstolonin B (Ssn B), exerted anti-inflammatory effects in various diseases, but not yet in OA. On the basis of this evidence, our works purposed to evaluate the effect of Ssn B on free fatty acid (FFA) palmitate (PA)-stimulated human osteoarthritic chondrocytes and obesity-associated mouse OA model. We found that Ssn B suppressed PA-triggered inflammatory response and extracellular matrix catabolism in a concentration-dependent approach. In vivo, Ssn B treatment inhibited cartilage degeneration and subchondral bone calcification caused by joint mechanical imbalance and alleviated metabolic inflammation in obesity. Mechanistically, co-immunoprecipitine and molecular docking analysis showed that the formation of toll-like receptor 4 (TLR4)/myeloid differentiation protein-2 (MD-2) complex caused by PA was blocked by Ssn B. Subsequently, it leads to inactivation of PA-caused myeloid differentiation factor 88 (MyD88)-dependent nuclear factor-kappaB (NF-κB) cascade. Together, these findings demonstrated that Ssn B is a potential treatment agent for joint degenerative diseases in obese individuals.

Displacements of a spatially limited light beam in the slant path of oceanic turbulence.

The new oceanic power spectrum of refractive-index of optical turbulent fluctuations in slant path is developed by oceanic temperature structure parameters with depth under weak wind and strong wind conditions. Based on the proposed oceanic power spectrum in slant channel, the analytical expression of the displacement variance of Gaussian beam propagation in slant oceanic turbulent channel is derived. Then the influence of oceanic turbulent parameters in slant path on the beam displacement is investigated. It's shown that oceanic turbulence in slant path with small inner scale, low ratio of temperature and salinity contributions, large tidal velocity and wind speed leads to small beam displacement. For a sufficiently large receiver radius, Gaussian beam with large initial beam radius propagating at large zenith angle can cause small beam displacement in slant path of oceanic turbulence.

Application of Microwave Transmission Sensors for Water Cut Metering under Varying Salinity Conditions: Device, Algorithm and Uncertainty Analysis.

The measurement of water cut in crude oil is an essential procedure in petroleum production and it is desirable to obtain these data through an automatic and real-time method. Microwave sensors can be used for the task, and they are safe, robust and can cover the whole water cut range. However, they are relatively susceptible to the water conductivity and temperature, and the algorithms for addressing these problems are still rare in the literature. In this paper, a microwave transmission sensor that can measure the water cut under varying salinity conditions is proposed, and the algorithm for solving the water cut and salinity simultaneously with the measured amplitude and phase is described in detail. Experiments under different water cut and salinity conditions are conducted, and the results are used to verify the model and algorithm. Finally, a simplified and fast method for uncertainty analysis is proposed and applied to the iteration algorithm under test conditions. It can be concluded that accuracy higher than 95% in the water cut measurements can be expected under the 0~100% water cut range, and an error of about 10% in the water conductivity is achievable under water-continuous flow conditions. The uncertainty analysis shows that the calculated water cut and salinity results are negatively correlated, and the water salinity uncertainty tends to be larger than the water cut uncertainty. When the water salinity is high, the water cut uncertainty tends to be high whereas the water salinity uncertainty tends to be low.

[Effects of rice wheat intervention on intestinal microflora of rats based on metagenomics].

OBJECTIVE: To investigate the effects of rice on intestinal microflora in rats. METHODS: Thirty 4-week-old male SD rats were randomly divided into control group, rice group and wheat group according to body weight. The control group was fed with AIN-93 diet, the rice group and the wheat group was fed with the AIN-93 diet which the carbohydrate was replaced with rice and wheat, respectively, for 4 weeks. At the end of the experiment, lipid related biochemical indexes were determined, and the contents of the distal colon(feces) of rats were collected for macro factor detection. RESULTS: From the beginning to the end of feeding, there was no difference in weight gain among the groups. After the end of the experiment, there was no difference among lipid-related indicators and blood glucose. α diversity showed that there was no difference in the diversity of intestinal microbiota between the rice and wheat groups, and the gene abundance analysis of intestinal microbiota in the wheat group showed that the gene abundance of intestinal microbiota was lower. The difference analysis of intestinal microbiota result showed that compared with the rice group, the wheat group was composed of higher proportion of verrucomicrophyla and lower proportion of Bacteroidetes. Lefse analysis showed that the surface group was enriched with Akkermansia Muciniphila, Bifidobacterium animalis, and a variety of beneficial bacteria such as Faecalibaculum rodentium and Intestinimonas butyriciproducens, while Prevotella copri was rich in the rice group. Glycoside hydrolases 8, glycoside hydrolases 16, glycoside hydrolases 99 and glycosyl transferase family 56. CONCLUSION: Rice or wheat as different carbohydrate sources have different effects on the composition of intestinal microflora and carbohydrate-related active enzymes in rats.

Improvement of multiterritory perforator flap survival supported by a hybrid perfusion mode: A novel strategy and literature review.

Perforator flaps have been widely used in clinical Settings, however, unexpected necrosis was still commonly encountered in the distal portions of multiterritory flaps known as Choke zone III. In this study, we introduced a novel hybrid perfusion technique which is different from the established one of arterial supercharging or venous superdrainage to improve multiterritory flap survival with success. In order to ensure the entire flap survival of multiterritory flaps extending to choke zone III, a "hybrid perfusion" mode by anastomosing a distal vein of the flap with a recipient artery was carried out in two cases based on our previous basic study. In addition, a systematic literature review regarding the established microsurgical assistant techniques of arterial supercharging and venous superdrainage techniques were performed. Both flaps survived uneventfully. At a minimal follow-up of six months, both patients were satisfied with the results. This novel hybrid perfusion technique provides a simple new concept in solving partial necrosis of multiterritory flaps. Further practice is guaranteed for better understanding this unconventional attempt.

Spatial variation in macrobenthic assemblages and their relationship with environmental factors in the upstream and midstream regions of the Heihe River Basin, China.

The Heihe River is a typical inland river under increasing anthropogenic pressure. To explore the characteristics of the macrobenthic assemblages and their relationships with environmental factors in the upstream and midstream regions of this basin, abiotic conditions and macrobenthic assemblages were investigated in the summers of 2018 and 2019. A total of 50 species were collected, and Arthropoda and mollusks were the dominant groups. A significant increase in standing stock was observed from the upstream to midstream, and predators (PR) were the main functional feeding group. A one-way analysis of variance (ANOVA) revealed that the Shannon-Wiener index and Margalef's index values significantly differed at the spatial scale (P < 0.05). A redundancy analysis (RDA) and Pearson correlation analysis showed that the spatial heterogeneity of the macrobenthos was influenced by the biochemical oxygen demand (BOD5), water temperature (WT), total nitrogen (TN), salinity, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), and potassium permanganate index (CODMn) (P < 0.05). The spatial variation of macrobenthos was mainly governed by natural conditions and human disturbances.

Spectrum-efficient hybrid PAM-DMT for intensity-modulated optical wireless communication.

In optical wireless communication (OWC), the superimposed optical orthogonal frequency division multiplexing (O-OFDM), such as layered asymmetrically clipped O-OFDM (LACO-OFDM), can improve spectrum efficiency by appropriately combining multiple O-OFDM signals for simultaneous transmission. However, it suffers from increased receiver complexity and latency. Therefore, a novel architecture of hybrid pulse-amplitude-modulated discrete multitone modulation (HPAM-DMT) is proposed in this paper to support a spectrum-efficiency OWC link. In HPAM-DMT, a PAM-DMT signal is carefully designed by using the real parts of subcarriers and is then superimposed on the classic PAM-DMT signal for simultaneous transmission, which fully exploits the spectrum in terms of subcarriers. Moreover, thanks to the well-designed aritecture of the two superimposed PAM-DMT signals, the proposed HPAM-DMT achieves the same spectrum efficiency as the LACO-OFDM, with much lower complexity and latency. Notable improvement of the bit-error rate (BER) performance is observed for the proposed HPAM-DMT compared to LACO-OFDM under the corruption of the transmitter nonlinearity. Moreover, HPAM-DMT achieves a relatively higher power efficiency than conventional O-OFDM schemes, which makes it a competitive O-OFDM scheme for IM/DD-based OWC.

Gut microbial composition changes in bladder cancer patients: A case-control study in Harbin, China.

BACKGROUND AND OBJECTIVES: This study aimed to explore the changes of gut bacteria in bladder cancer patients. METHODS AND STUDY DESIGN: Newly diagnosed bladder cancer patients were recruited. All participants completed a questionnaire about personal behavior and diet. Pyrosequencing of the total genomic DNA extracted from human feces was carried out by Illumina HiSeq 2000. The copy number of target DNA for bacteria was determined by real-time quantitative PCR assay. Fecal short chain fatty acids contents were measured by gas chromatography (GC) analysis. The concentrations of lipopolysaccharide and D-lactic acid in serum were determined by enzyme-linked immunosorbent assay kits. RESULTS: Fruit intake was significantly lower than in healthy controls. The numbers of Clostridium cluster XI and Prevotella in bladder cancer patients decreased. The numbers of domain bacteria and Prevotella were significantly and positively associated with fruit intake (r=0.002, p<0.05 for domain bacteria; r=0.004, p<0.05 for Prevotella). The concentration of butyric acid decreased significantly in bladder cancer patients, and the quantities of fecal butyric acid were significantly and positively associated with fruit intake (r=0.610, p<0.01). The concentrations of lipopolysaccharide and D-lactic acid, two sensitive markers of gut permeability, were greater in bladder cancer patients. CONCLUSIONS: Dysbiosis of gut microbiota, decreased butyric acid concentrations and impaired intestinal structural integrity were found in bladder cancer patients, which might be associated with inadequate fruit intake.

Comprehensive analysis of aberrantly expressed profiles of messenger RNA in alcoholic liver disease.

BACKGROUND: Alcoholic liver disease (ALD) is one of the major cause of morbidity and mortality of clinical liver disease worldwide. Until today, although many general therapies are carried out and several molecular targets have been proposed to act as the potential therapeutic targets, more accurate molecular targets and more effective therapeutic methods remain needed. MATERIAL AND METHODS: In the study, we analyze the differential expression genes (DEGs) between the patients with ALD and healthy controls. Gene Ontology enrichment and KEGG signaling pathway analysis are performed to identify the function of DEGs. Some significant molecules are proposed to act as the potential therapeutic targets for ALD. RNA data of 15 ALD tissues and 7 normal tissues for RNA expression analysis were obtained. DEGs in ALD samples compared with normal tissues identified through the limma R package and subjected to network analysis. RESULTS: As a result, we obtained a total of 274 DEGs that mainly involved in biological processes related to the angiogenesis, stress reaction, synthesis, and metabolism of organic acids. Network analysis obtained several genes with high network degree and fold change. Some significant molecules are proposed to act as the potential therapeutic targets for ALD. CONCLUSIONS: Our research identified some new progression-related genes of alcohol liver diseases, which could be regarded as the new targets for the early diagnosis and therapeutic management in ALD.

Extraction of Peptidoglycan from L. paracasei subp. Paracasei X12 and Its Preliminary Mechanisms of Inducing Immunogenic Cell Death in HT-29 Cells.

L. paracasei subp. paracasei X12 was previously isolated from a Chinese traditional fermented cheese with anticancer activities and probiotic potential. Herein, the integral peptidoglycan (X12-PG) was extracted by a modified trichloroacetic acid (TCA) method. X12-PG contained the four representative amino acids Asp, Glu, Ala and Lys, and displayed the similar lysozyme sensitivity, UV-visible scanning spectrum and molecular weight as the peptidoglycan standard. X12-PG could induce the production of apoptotic bodies observed by transmission electron microscopy (TEM). X12-PG could significantly induced the translocation of calreticulin (CRT) and the release of high mobility group box 1 protein (HMGB1), the two notable hallmarks of immunogenic cell death (ICD), with the endoplastic reticulum (ER) damaged and subsequently intracellular [Ca(2+)] elevated. Our findings implied that X12-PG could induce the ICD of HT-29 cells through targeting at the ER. The present results may enlighten the prospect of probiotics in the prevention of colon cancer.

Rhizospheric microbiota of suppressive soil protect plants against Fusarium solani infection.

BACKGROUND: Fusarium infection has caused huge economic losses in many crops. The study aimed to compare the microbial community of suppressive and conducive soils and relate to the reduction of Fusarium wilt. RESULTS: High-throughput sequencing and microbial network analysis were used to investigate the differences in the rhizosphere microbiota of the suppressive and conducive soils and to identify the beneficial keystone taxa. Plant pathogens were enriched in the conducive soil. Potential plant-beneficial microorganisms and antagonistic microorganisms were enriched in the suppressive soil. More positive interactions and keystone taxa existed in the suppressive soil network. Thirty-nine and 16 keystone taxa were identified in the suppressive and conducive soil networks, respectively. Sixteen fungal strains and 168 bacterial strains were isolated from suppressive soil, some of which exhibited plant growth-promotion traits. Thirty-nine bacterial strains and 10 fungal strains showed antagonistic activity against F. solani. Keystone taxa Bacillus and Trichoderma exhibited high antifungal activity. Lipopeptides produced by Bacillus sp. RB150 and chitinase from Trichoderma spp. inhibited the growth of F. solani. Microbial consortium I (Bacillus sp. RB150, Pseudomonas sp. RB70 and Trichoderma asperellum RF10) and II (Bacillus sp. RB196, Bacillus sp. RB150 and T. asperellum RF10) effectively controlled root rot disease, the spore number of F. solani was reduced by 94.2% and 83.3%. CONCLUSION: Rhizospheric microbiota of suppressive soil protects plants against F. solani infection. Antagonistic microorganisms in suppressive soil inhibit pathogen growth and infection. Microbial consortia consisted of keystone taxa well control root rot disease. These findings help control Fusarium wilt. © 2024 Society of Chemical Industry.

Curcumin Improves Functional Recovery of Ruptured Tendon by Promoting Tenogenesis via PI3K/Akt Signaling.

OBJECTIVE: In our previous study, we found that local release of curcumin from nanomicelles prevents peritendinous adhesion during Achilles tendon healing. The aim of this study is to further investigate the signaling integrated by curcumin to direct the tenogenetic program of tendon stem cells contributing to tendon healing. METHODS: A surgical model of tendon rupture and repair (TRR) was established in rats. Peritendinous adhesion and inflammation, biomechanical function, and expression of ß-catenin and epithelial cellular adhesion molecule (EpCAM) were determined. A dataset was analyzed to investigate differentially expressed genes and enriched genes related to the signaling pathways. Tendon stem cells were treated with curcumin to investigate the cellular and molecular events as well as the signaling pathway. RESULTS: In rat TRR model, curcumin treatment resulted in not only significantly decreased peritendinous inflammatory but also improved tendon functional recovery along with significantly increased expressions of EpCAM and ß-catenin. Analysis of the dataset indicated that the enriched genes were positively related to differentiation pathways but negatively related to proliferation pathways. In rat tendon stem cells, curcumin treatment inhibited proliferation but promoted differentiation. Curcumin's antioxidative activity was associated with tenogenesis. The upregulated expression of tendon lineage-specific markers was dependent on phosphatidylinositol 3'-kinase/Akt (PI3K/Akt) pathway which could be a potential mechanism of tenogenesis of curcumin treatment. CONCLUSION: Curcumin could improve tendon functional recovery via promoting tenogenesis in addition to its antioxidant and anti-inflammatory activities. Curcumin induced differentiation of tendon stem/progenitor cell into tenocytes via PI3K/Akt signaling pathway. This finding provided evidence for the application of curcumin to prevent adhesion during tendon repair.

Identification of the prognostic biomarkers and their correlations with immune infiltration in colorectal cancer through bioinformatics analysis and in vitro experiments.

Colorectal cancer (CRC) is the third most diagnosed malignancy and the second leading cause of cancer death. The objective was to identify novel hub genes that were helpful for prognosis and targeted therapy in CRC. GSE23878, GSE24514, GSE41657, GSE81582 were filtered from the gene expression omnibus (GEO). Differentially expressed genes (DEGs) were identified through GEO2R, which were enriched in the GO term and KEGG pathway in DAVID. PPI network was constructed and analyzed using STRING and hub genes were screened out. The relationships between hub genes and prognoses in CRC were evaluated in GEPIA based on the cancer genome atlas (TCGA) and genotype-tissue expression (GTEx). The transcription factors and miRNA-mRNA interaction networks for hub genes were performed using miRnet and miRTarBase. The relationship between hub genes and tumor-infiltrating lymphocytes were analyzed in TIMER. The protein levels of hub genes were identified in HPA. The expression levels of hub gene in CRC and its effect on the biological effect of CRC cells were identified in vitro. As hub genes, the mRNA levels of BIRC5, CCNB1, KIF20A, NCAPG, and TPX2 were highly expressed in CRC and had excellent prognostic value. The BIRC5, CCNB1, KIF20A, NCAPG, and TPX2 were closely associated with transcription factors, miRNAs, tumor-infiltrating lymphocytes, suggesting their involvement in the regulation of CRC. BIRC5 highly expressed in CRC tissues and cells, and promoted the proliferation, migration, and invasion of CRC cells. BIRC5, CCNB1, KIF20A, NCAPG, and TPX2 are hub genes that serve as promising prognostic biomarkers in CRC. BIRC5 plays an important role in the development and progression of CRC.

Effects of health qigong exercise on upper extremity muscle activity, balance function, and quality of life in stroke patients.

Introduction: This study explored the effects of Qigong exercises on upper extremity muscle activity, balance function, and quality of life in stroke patients. Methods: A total of 30 stroke patients were randomly allocated to either control group or Qigong group. In the Qigong group, participants completed an intervention of Qigong Baduanjin over 8 weeks. Data on the electromyographic activities of the biceps brachii muscle, triceps brachii muscle, and muscle coordination were obtained using surface electromyography and the co-contraction ratio (CCR). Data on balance were obtained using the PK254P balance function detection system. Quality of life was measured using the brief version of the World Health Organization Quality of Life scale. Results: The results for the Qigong group showed a significant difference in CCR of the triceps brachii muscle (p < 0.01). Concerning balance (assessed using the open-eye test), there was a significant decrease (p < 0.05) in Y-axis trajectory deviations and the Y-axis speed in the Qigong group. In the closed-eye test, the peripheral area of the Qigong group was significantly lower than that of the control group (p < 0.05). Significant differences were also observed in physical health (p < 0.05), psychological health (p < 0.01), environment (p < 0.01), and the total scores for quality of life (p < 0.01) in the Qigong group. Discussion: We conclude that Qigong exercises improve the quality of life in stroke patients and have positive effects on the coordination of limb extremities and balance function.

The emerging role of pyroptosis in neuropathic pain.

Neuropathic pain caused by somatosensory system injuries is notoriously difficult to treat. Previous research has shown that neuroinflammation and cell death have been implicated in the pathophysiology of neuropathic pain. Pyroptosis is a form of programmed cell death associated with inflammatory processes, as it can enhance or sustain the inflammatory response by releasing pro-inflammatory cytokines. This review presents the current knowledge on pyroptosis and its underlying mechanisms, including the canonical and noncanonical pathways. Moreover, we discuss recent findings on the role of pyroptosis in neuropathic pain and its potential as a therapeutic target. In conclusion, this review highlights the potential significance of pyroptosis as a promising target for developing innovative therapies to treat neuropathic pain.
