ABSTRACT The plastic film materials are a widely used agricultural means of production. Recently, two types of new agricultural film mulches are developed and are used popularly. They are ethylene-vinyl acetate copolymer (EVA) and polyolefin (PO) film mulches. The transmittances of film mulches are related to thermal reservation and plant photosynthesis. We experimentally measure transmittances of several EVA and PO film mulches under different wavelengths. We also find that the transmittances of mulches vary with light intensity change at one wavelength. The variable transmittances for these mulches are also measured in experiments. These data measured can provides help for agricultural production and accurate numerical simulation for the establishment microclimate of plastic greenhouse, even the degradation of plastic films. Recently popularly ethylenevinyl ethylene vinyl (EVA (PO photosynthesis wavelengths wavelength experiments greenhouse films

ABSTRACT The yield of crops has a significant impact on economic and social development. It is significant to ensure the healthy growth of crops. Leaves can represent the growth of crops. Crop health can be monitored by analyzing a sufficient number of leaf images. But advanced farming techniques make leaves less susceptible to pests and diseases. Therefore, it is difficult to collect enough leaves with pests and diseases for image analysis. To solve this problem, this research proposed a method based on few-shot learning to identify crop leaf images and judge crop health status. The main structure of the method is a siamese network. The structure of its two subnetworks is the convolution neural network with an attention module. Each subnetwork outputs a feature vector. Measuring the distance of two feature vectors in the feature space, the similarity is calculated. Then the categories of leaf pests and diseases are judged. The experiments in this research were carried out on apple and potato leaves. The accuracy of identifying their pests and diseases reached 98.03% and 97.34% respectively. The experiment proved that when the sample size is small. The method proposed can effectively identify crop leaf pests and diseases.

Different Al2O3 carriers were synthesized by co-precipitation and sol-gel method. From them, 4%NiO-20%MoO3/Al2O3 catalysts were prepared by incipient wetness impregnation. The catalysts were characterized by X-ray diffraction analysis (XRD), N2 adsorption-desorption, NH3 temperature programmed desorption (TPD) and H2-temperature programmed reduction (TPR) and subsequently used for selective hydrogenation of naphthalene to high-value tetralin. The results showed that Ni-Mo/so-ge Al2O3 (900) exhibited better catalytic performance than Ni Mo/commercial Al2O3, achieving 99.56% naphthalene conversion and 99.43% tetralin selectivity.

SUMMARY: To clarify the path of the temporal branch of facial nerve (TB) crossing the zygomatic arch (ZA). Eighteen fresh adult heads specimens were carefully dissected in the zygomatic region, with the location of TB as well as its number documented. The hierarchical relationship between the temporal branch and the soft tissue in this region was observed on 64 P45 plastinated slices. 1. TB crosses the ZA as type I (21.8 %), type II (50.0 %,), and type III (28.1 %) twigs. 2. At the level of the superior edge of the ZA, the average distance between the anterior trunk of TB and the anterior part of the auricle is 36.36±6.56 mm, for the posterior trunk is 25.59±5.29 mm. At the level of the inferior edge of the ZA, the average distance between the anterior trunk of TB and the anterior part of the auricle is 25.77±6.19 mm, for the posterior trunk is 19.16±4.71 mm. 3. The average length of ZA is 62.06±5.36 mm. TB crosses the inferior edge of the ZA at an average of 14.67±6.45 mm. TB crosses the superior edge of the ZA at an average of 9.08±4.54 mm. 4. At the level of the ZA, TB passes on the surface of the pericranium while below the SMAS. The TB obliquely crosses the middle 1/3 part of the superior margin of the ZA and the junction of the middle 1/3 part and the posterior 1/3 part of the inferior margin of the ZA below the SMAS while beyond the periosteum. It is suggested that this area should be avoided in clinical operation to avoid the injury of TB.

RESUMEN: El objetivo de estudio fue esclarecer el trayecto del ramo temporal del nervio facial (RT) que cruza el arco cigomático (AC). Se disecaron la región cigomática de 18 especímenes de cabezas sin fijar de individuos adultas y se documentó la ubicación del RT y su número de ramos. La relación jerárquica entre el ramo temporal y el tejido blando en esta región se observó en 64 cortes plastinados o P45. 1º El RT cruza el AC como tipo I (21,8 %), tipo II (50,0 %) y tipo III (28,1 %). 2º A nivel del margen superior del AC, la distancia promedio entre el tronco anterior de RT y la parte anterior de la aurícula fue de 36,36±6,56 mm, para el tronco posterior fue de 25,59±5,29 mm. A nivel del margen inferior del AC, la distancia promedio entre el tronco anterior del RT y la parte anterior de la aurícula era de 25,77±6,19 mm, para el tronco posterior era de 19,16±4,71 mm. 3º La longitud media de RT fue de 62,06±5,36 mm. EL RT cruzaba el margen inferior del AC a una distancia media de 14,67±6,45 mm. El RT cruzaba el margen superior del AC a una distancia media de 9,08±4,54 mm. 4º Anivel del AC, el RT pasaba por la superficie del pericráneo mientras se encuentra por debajo del SMAS. El RT cruza oblicuamente el tercio medio del margen superior del AC y la unión del tercio medio y el tercio posterior del margen inferior del AC por debajo del SMAS, más allá del periostio. Se sugiere que esta área debe evitarse en la operación clínica para evitar la lesión de la RT.

Abstract A chitosan-based edible coating was prepared by incorporating γ-polyglutamic acid and curcumin. The physical, mechanical and antimicrobial properties of the chitosan/γ-polyglutamic acid/curcumin edible coating were characterized. Furthermore, the effect of chitosan/γ-polyglutamic acid/curcumin edible coating on the shelf-life of fresh beef was investigated. The γ-polyglutamic acid and curcumin incorporation greatly improved the performance of chitosan coating, including coating formation and antimicrobial activity. After the application of coating, the chitosan/γ-polyglutamic acid/curcumin edible coating had a good protection effect on the color of beef and was conducive to prolonging the shelf life of beef with good quality compared to pure curcumin edible coating. These results revealed that application of chitosan/γ-polyglutamic acid/ curcumin edible coating will be a good way to preserve freshness of fresh beef.

In this work, the effects of electric pulse treatment on the discharge and electrochemical properties of rolled and extruded AZ61 as anode of Mg-air battery were studied. The microstructure, electrochemical behavior and surface morphology after discharge were discussed to relate the discharge performance. The experimental results show that compared with the original magnesium anode (rolled and extruded), the magnesium anode treated by electric pulse has more negative corrosion potential, lower impedance value, higher discharge voltage and better specific energy. This is because electric pulse treatment can cause the coarse second phase in magnesium anode to dissolve and the grains to become more uniform. In particular, in the discharge process, the surface of magnesium anode after electric pulse treatment will form micro cracks, which is beneficial to promote the self-stripping of discharge products. It is worth noting that the effect of electric pulse treatment on rolled anode is better than that of extruded anode. It may be due to the different dislocation density in the two anodes. During the electric pulse treatment, the dislocation density in the alloy is highly correlated with the dissolution rate of β-Mg17Al12, which ultimately affects the volume fraction of the second phase in the alloy.

This work presented a new PEG modified calix[4]arene stationary phase (C4A-PEG-2PTSC) for gas chromatographic (GC) separations. The statically coated C4A-PEG-2PTSC column exhibited moderate polarity and column efficiency of 2224 plates m-1 determined by 1-octanol at 120 oC. The results showed that the C4A-PEG-2PTSC column exhibited the good separation performance for various types of analytes containing halogenated benzenes, benzaldehydes, phenols, alcohols, anilines isomers and showed the different retention behavior with the comparative columns. Importantly, it showed the better separation capacity of toluidine and xylidine isomers than commercial HP-35 column. Moreover, it was applied in practical sample analysis to detect the content of isomer impurities. This work exhibited the good application potential of C4A-PEG-2PTSC stationary phase in GC analyses.

Abstract Background Osteoarthritis (OA) is one of the most frequent chronic diseases with high morbidity worldwide, marked by degradation of the cartilage and bone, joint instability, stiffness, joint space stenosis and subchondral sclerosis. Due to the elusive mechanism of osteoarthritis (OA), we aimed to identify potential markers for OA and explore the molecular mechanisms underlying OA. Methods Expression profiles data of OA were collected from the Gene Expression Omnibus database to identify differentially expressed mRNAs (DEmRNAs) and differentially expressed lncRNAs (DElncRNAs) in OA. Functional annotation and protein–protein interaction (PPI) networks were performed. Then, nearby DEmRNAs of DElncRNAs was obtained. Moreover, GO and KEGG pathway enrichment analysis of nearby DEmRNAs of DElncRNAs was performed. Finally, expression validation of selected mRNAs and lncRNAs was performed by quantitative reverse transcriptase-polymerase chain reaction. Results In total, 2080 DEmRNAs and 664 DElncRNAs were determined in OA. PI3K-Akt signaling pathway, Endocytosis and Rap1 signaling pathway were significantly enriched KEGG pathways in OA. YWHAB, HSPA8, NEDD4L and SH3KBP1 were four hub proteins in PPI network. The AC093484.4/TRPV2 interact pair may be involved in the occurrence and development of OA. Conclusion Our study identified several DEmRNAs and DElncRNAs associated with OA. The molecular characters could provide more information for further study on OA.

In this work, the influence of rolling passes on microstructure, corrosion behavior, electrochemical performance, and battery performance of AZ31 magnesium alloy was studied. The experimental results show that the grain size decreases first and then increases with rolling passes. Among them, the grain size of three passes rolled sample is the smallest, while the grain size of the four passes rolled sample is obviously refined and evenly distributed, accompanied by a small number of twins. Therefore, it exhibits more muscular discharge activity. In addition, the corrosion products of the four passes rolled samples are distributed loosely and evenly on the surface during immersion, which is easy to fall off, thus reducing the polarization. The surface of the discharged four passes rolled sample is flat, indicating that the dissolution is uniform, conducive to promoting the self-peeling of discharge products. The results show that the samples with four passes of rolling have high electrochemical activity and anode efficiency. The average cell voltage and anodic efficiency of the four passes rolled anode for Mg-air battery within 5 h at 10 mA cm-2 were 1.065 V and 56.4%, respectively. Therefore, the electrochemical performance of the four passes rolled sample is the best, and the process is more suitable for preparing magnesium alloy anode plate.

Resumen La cirugía desempeña un papel insustituible en la prevención, diagnóstico, estadificación, reconstrucción y rehabilitación en el tratamiento global del cáncer. Sin embargo, es difícil que cirujanos y personal de enfermería tengan en cuenta todos los aspectos de la gestión de la medicación, como el impacto de la cirugía en la función física del paciente y la complejidad del tratamiento antitumoral con sus comorbilidades. Los servicios de atención farmacéutica que anteriormente prestaban los farmacéuticos en oncología se centraban más en aspectos de la medicina interna, y no ampliamente en el ámbito quirúrgico. En la actualidad, el modo de trabajo farmacéutico en la cirugía oncológica aún no está definido en China, y existe una necesidad de mejorar la gestión de la medicación de todo el proceso asistencial. En 2015, la Asociación Farmacéutica de GuangDong propuso la creación del rol de farmacéutico quirúrgico en China y posteriormente creó su puesto de trabajo. En 2021, la Asociación Farmacéutica de GuangDong estableció una nueva disciplina denominada “farmacia quirúrgica”, que es el área de conocimiento de los farmacéuticos quirúrgicos, y también intentó diferenciar la farmacia quirúrgica en distintas subáreas, como la farmacia quirúrgica oncológica. Este artículo presenta el modo de trabajo de los farmacéuticos quirúrgicos en China, que proporciona servicios de atención farmacéutica en el periodo perioperatorio de los pacientes incorporando los distintos aspectos del tratamiento antitumoral, control de infecciones, anestesia, anticoagulación, control de la presión arterial y la glucosa en sangre, nutrición y tratamiento del dolor, con el objetivo de mejorar la calidad de vida de los pacientes.

Abstract Surgery plays an irreplaceable role in the prevention, diagnosis, staging, reconstruction, and rehabilitation in the overall management of cancer. Nevertheless, it is difficult for surgeons and nurses to take into account the details of medication management, considering the impact of surgery on the patient’s physical function and the complexity of anti-tumor treatment with comorbidity. The pharmaceutical care services previously provided by pharmacists in oncology focus more on the internal medicine system, not widely the surgical field. At present, the pharmaceutical working mode in oncology surgery has not well been formed around China, and the whole process medication management needs to be improved. In 2015, the GuangDong Pharmaceutical Association came up with the concept of surgical pharmacist in China and subsequently created its position. In 2021, the GuangDong Pharmaceutical Association established a new discipline termed “surgical pharmacy”, which is the knowledge system of surgical pharmacists, and also tried to differentiate surgical pharmacy into diverse areas, such as oncology surgical pharmacy. This article introduced a working mode of surgical pharmacists in China that providing pharmaceutical care services in perioperative period around anti-tumor, anti-infection, anesthesia, anticoagulation, blood pressure, blood glucose, nutrition, and pain management, to improve quality of life for patients.

Abstract Introduction: hypertension and diabetes are chronic disorders associated with an increased risk of cardiovascular disease. Objectives: to evaluate the effect of 52 % low-sodium salt applied to the Chinese-modified DASH (CM-DASH) diet on risk of atherosclerotic cardiovascular disease (ASCVD) in patients with hypertension and type-2 diabetes. Methods: the low-sodium salt group (LSSG) took 5 g/day of 52 % low-sodium salt plus CM-DASH diet for 8 weeks, while the normal-sodium salt group (NSSG) took the same dose of normal-sodium salt plus CM-DASH diet for 8 weeks. Blood tests, 24-hour urine tests, anthropometric measurements, and 10-year risk of ASCVD prediction were assessed. Results: compared with baseline, both LSSG and NSSG showed a significant reduction in 10-year risk of ASCVD, but we did not find any statistically significant differences in 10-year risk of ASCVD between LSSG and NSSG. Conclusions: our study shows that salt limits and DASH diets reduce the risk of cardiovascular disease whereas low-sodium salt containing 52 % sodium chloride did not significantly lower the risk of cardiovascular disease when compared to regular salt. Due to the limitations of the research, additional studies will be necessary to confirm our findings.

Resumen Introducción: la hipertensión y la diabetes son trastornos crónicos asociados a un mayor riesgo de enfermedad cardiovascular. Objetivos: evaluar el efecto de la sal baja en sodio (52 %) aplicada a la dieta DASH modificada en China (CM-DASH) sobre los riesgos de enfermedad cardiovascular aterosclerótica (ECA) en pacientes con hipertensión arterial y diabetes de tipo 2. Métodos: el grupo de sal baja en sodio (LSSG) tomó 5 g/día de sal baja en sodio al 52 % más dieta CM-DASH durante 8 semanas, mientras que el grupo de sal normal en sodio (NSSG) tomó la misma dosis de sal normal en sodio más dieta CM-DASH durante 8 semanas. Se evaluaron los análisis de sangre, los análisis de orina de 24 horas, las mediciones antropométricas y los riesgos de predicción de ECVA a 10 años. Resultados: en comparación con el valor basal, tanto el LSSG como el NSSG mostraron una reducción significativa de los riesgos a 10 años de ECVA, mientras que no se encontraron diferencias estadísticamente significativas en los riesgos a 10 años de ECVA entre el LSSG y el NSSG. Conclusiones: nuestro estudio muestra que los límites de sal y las dietas DASH reducen el riesgo de enfermedad cardiovascular mientras que la sal baja en sodio con un 52 % de cloruro sódico no redujo significativamente el riesgo de enfermedad cardiovascular en comparación con la sal normal. Debido a las limitaciones de la investigación, serán necesarios estudios adicionales para confirmar nuestros hallazgos

Abstract Transforming growth factor β1 (TGF-β1) is a polypeptide growth factor with various biological activities. Recent studies have shown that this growth factor and they receptors are expressed in human Leydig cells, Sertoli cells, spermatogonia, spermatocytes and sperm cells after birth, and are involved in the endocrine regulation of spermatogenesis. However, there is no report on the expression of TGF-β in human embryonic testis. TGF-β1 is a peptide growth factor widely distributed in germ cells at various levels in the testis, regulating the function of the testes and maintaining the stability of the testis environment by acting on various cells. This review summarizes the research progress of TGF-β1 in human testis.

Abstract The influences of 3-N-butyphthalide (NBP) on early brain injury (EBI) induced via mild subarachnoid hemorrhage (SAH) and its mechanism were explored. Establishment of SAH model was via autologous blood injection. The protection of NBP on EBI in SAH model mice was evaluated. Determination of neuronal apoptosis was conducted. Detection of blood brain barrier (BBB), ZO-1, claudin-5, occludin and MMP-9 was manifested. The effects of NBP on oxidative stress, inflammation, and the SIRT1/NF-κB and the LKB-1/AMP-activated protein kinase (AMPK) pathways were investigated. NBP could alleviate neurological deficits and BBB dysfunction, repress cerebral edema and mitigate brain histomorphology. NBP repressed apoptosis in brain tissues, oxidative stress, inflammation, NF-κB activity but facilitated SIRT1. Finally, NBP activated the LKB-1/AMPK pathway. NBP may lighten BBB dysfunction, oxidative stress, inflammation and apoptosis after SAH via activating the LKB-1/AMPK pathway, thereby mitigating EBI.
