ABSTRACT
ObjectiveTo explore the clinical application law and provide literature support and development ideas for the modern application of fresh Plantaginis Herba. MethodThe literature about the application of fresh Plantaginis Herba was retrieved from the fifth edition of Chinese medical dictionary， China national knowledge infrastructure （CNKI）， VIP， Wanfang data， and Chinese medical journals and analyzed. ResultFresh Plantaginis Herba appeared frequently in ancient books， with the effects of clearing heat， cooling blood， promoting urination， and relieving stranguria. It was used for the treatment of stranguria， urine retention， bloody urine， sore and carbuncle， epistaxis， red and swelling eye， suppurative inflammation in the throat， and gynecological and pediatric diseases. According to modern medical publications， fresh Plantaginis Herba is mainly used to treated diseases in the kidney， five sense organs， spleen， stomach， lung， liver， gallbladder， and skin and gynecological and pediatric diseases. Specifically， it is mainly used to treat the syndrome of dampness and heat in kidney and skin diseases caused by the accumulation of dampness and heat toxin， with the effects of clearing heat， removing toxin， promoting urination， and relieving stranguria. Since ancient times， there have been reports of using fresh Plantaginis Herbausing for food and health care. ConclusionFresh Plantaginis Herba is widely used in clinical practice and has a high medical value and economic value. However， its modern application lags behind， so it is necessary to promote the development of fresh Plantaginis Herba from the aspects of medicinal material production， storage， transportation， preparation research and development， and clinical application.
ABSTRACT
ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma（GRR） decoction pieces produced by fresh and traditional cutting， and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process， and high performance liquid chromatography（HPLC） fingerprint of the standard decoction was established and performed on an Agilent EC-C18 column（4.6 mm×150 mm， 2.7 μm） with acetonitrile（A）-0.1% phosphoric acid aqueous solution（B） as the mobile phase for gradient elution（0-23 min， 18%-21%A； 23-35 min， 21%-28%A； 35-80 min， 28%-32%A）， and the detection wavelength was 203 nm. Then similarity evaluation， principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection（VIP） value>1. Quantitative analysis was carried out on the screened known differential components， and combined with the indicators of the dry extract rate and the transfer rate， to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950， and 18 common peaks were identified， including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg1， Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces， while the contents of ginsenoside Rb1， Rc ， Rb2 and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg1， Re， Rb1 and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces， while the contents of ginsenoside Rc ， Rb2 and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces， the average transfer rates of ginsenoside Rg1， Rb1， Rc， Rb2 and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased（P<0.05）， and the average transfer rate of ginsenoside Re and Rd also increased， but the difference was not statistically significant. ConclusionThe dry extract rate， content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces， which can provides data support for the subsequent clinical application of fresh cutting products.

ABSTRACT
Abstract Bacteria were isolated from samples of Fresh Apple juices from shops of three different localities of Lahore. Analysis of samples from Liberty, Anarkali and Yateem khana Markets show different levels of contamination. There were pathogenic and non-pathogenic bacteria in all samples and were identified by the morphological and biochemical tests. Most of the plasmids of pathogenic bacteria were 4kb in their molecular size. Ribotyping of 16S ribosomal RNA gene sequencing was done to confirm Helicobacter pylori strain and Gluconobacter oxydans. The highest sensitivity of 210mm was shown by Enterobacter sp. against Aztheromysine disk (15µg) while Micrococcus sp. was highly resistant against all of the Antibiotics applied. The antibiotic resistance of pathogenic bacteria was also checked against Ricinus communis plant's extracts, all isolated bacterial pathogens were resistant but only, E.coli was inhibited at 300µl of the extracts. Presence of pathogenic bacteria in Apple juice samples was due to contamination of sewage water in drinking water while some of these pathogenic bacteria came from Apple's tree and other from store houses of fruits.
Resumo As bactérias foram isoladas de amostras de suco de maçã fresco de lojas de três diferentes localidades de Lahore. A análise de amostras dos mercados Liberty, Anarkali e Yateem khana mostram diferentes níveis de contaminação. Havia bactérias patogênicas e não patogênicas em todas as amostras e foram identificadas pelos testes morfológicos e bioquímicos. A maioria dos plasmídeos de bactérias patogênicas tinha 4 kb em seu tamanho molecular. A ribotipagem do sequenciamento do gene do RNA ribossômico 16S foi realizada para confirmar a cepa de Helicobacter pylori e Gluconobacter oxydans. A maior sensibilidade de 210 mm foi mostrada por Enterobacter sp. contra disco de azteromisina (15µg) enquanto Micrococcus sp. foi altamente resistente a todos os antibióticos aplicados. A resistência a antibióticos de bactérias patogênicas também foi verificada contra extratos de plantas de Ricinus communis, todos os patógenos bacterianos isolados foram resistentes, mas apenas E. coli foi inibida em 300µl dos extratos. A presença de bactérias patogênicas nas amostras de suco de maçã deveu-se à contaminação da água de esgoto na água potável, enquanto algumas dessas bactérias patogênicas vieram da árvore da maçã e outras de armazéns de frutas.
ABSTRACT
Introduction: Fresh and smoked fish are widely consumed in Côte d'Ivoire as everywhere in West Africa. However, these foodstuffs, due to certain processing conditions, are likely to be contaminated by molds that produce dangerous mycotoxins. Objective: This study aimed to isolate and identify fungal strains contaminating fresh and smoked fish from the Sassandra River in Côte d'Ivoire. Place and Date of the Study: Sampling was carried out in various processing sites around the Sassandra River, particularly in the towns of Soubré and Guessabo. The microbiological analysis was carried out at Jean Lorougnon Guédé University in Daloa (Ivory Coast). Methods: A total of 108 samples of fresh and smoked fish were collected. Isolation and purification of fungal strains were carried out on Sabouraud medium with chloramphenicol. The identification of isolated strains was made on the basis of morphological and cultural criteria. Results: A total of 126 fungal strains were isolated, including 87 from the Guessabo samples and 39 from the Soubré samples from 54 fresh fish and 54 smoked fish. The predominant species were Aspergillus of the Glaucus group (39%), Aspergillus niger (36%) and Penicillium sp. (25%). Conclusion: This study shows that fresh and smoked fish from the Sassandra River in Côte d'Ivoire are contaminated by several strains of molds, some of which produce mycotoxins that can cause illness in consumers depending on their concentrations. It would therefore be appropriate to improve processing techniques.
ABSTRACT
Los captadores de niebla son usados para interceptar agua contenida en la niebla y abastecer de agua a comunidades que habitan en lugares donde este recurso escasea. Se evaluó el uso de captadores de niebla para la captación de agua en un área ubicada en el páramo Pan de Azúcar, Duitama-Boyacá. Se instalaron 60 captadores de niebla, 24 de ellos, con dispositivos para medir los volúmenes de agua interceptados. Los volúmenes de agua captados, se midieron en periodos de 24 horas, por 26 días, durante un año y se usó el modelo geométrico para diferenciar el agua proveniente de la niebla. La precipitación registrada fue mayor a la reportada en la literatura. La precipitación mensual osciló entre 51 y 1198 mm y la temperatura media mensual entre los 6 y 8 °C. Los volúmenes de agua promedio colectados por los 24 captadores de niebla estuvieron entre los 0,02 Lm-2dia-1 hasta los 4,4Lm-2dia-1. Los aportes de agua provenientes de la niebla oscilaron entre los 0,02 y 1,77 mmdía-1. La dirección del viento no afectó la captación de agua y aún se presenta incertidumbre al separar el aporte real de agua proveniente de la niebla a partir de la lluvia orográfica, lo cual, sigue siendo un desafío en los ecosistemas de páramo, por lo que se debe ampliar la investigación, para mejorar los diseños y las eficiencias de los captadores de niebla.
Fog collectors are used to intercept water contained in fog and supply water to communities that live in places where this resource is scarce. We evaluated the use of mist collectors to collect water in an area located in the Pan de Azúcar paramo, Duitama-Boyacá. We installed 60 mist collectors, 24 of them with devices to measure the volumes of water intercepted. The volumes of water captured were measured in periods of 24 hours for 26 days during one year and we used the geometric model to differentiate the water from the fog. The recorded precipitation was higher than that reported in the literature. Monthly rainfall ranged between 51 and 1198mm and mean monthly temperature ranged between 6 and 8°C. The average volumes of water collected by the fog collectors were below 0.5Lm-2day-1 with a maximum of 4.4Lm-2day-1. The contributions of water from the mist ranged between 0.02 and 1.77 mmday-1. The direction of the wind did not affect the capture of water and there is still uncertainty when separating the real contribution of water from the fog from the orographic rain, which continues to be a challenge in the paramo ecosystems, for which it is necessary to expand research, to improve the designs and efficiencies of fog collectors.
ABSTRACT
Abstract The authors report the case of a 71-year-old woman presented to the Emergency Department with acute ischemic stroke. She was treated with rt-PA and interventional endovascular revascularization and developed rapidly progressing angioedema that led to emergency intubation. The standard treatment was not very effective and the swelling improved after infusion of fresh frozen plasma. Angioedema after rt-PA infusion could be a life-threatening emergency that requires quick airway management by skilled professionals. As this condition is triggered by several factors, such as unregulated histamine and bradykinin production, the traditional treatment recommended by the guidelines may not be sufficient and the use of FFP can be considered as a safe and valuable aid.

【Objective】 To discuss the regulating effect of stored red blood cells (RBCs) transfusion on BMDMs in inflammatory conditions, and the relationship between stored RBCs transfusion and inflammatory response induced by bacterial infection. 【Methods】 Forty C57BL/6 male mice of 6-8 weeks (18-22 g/mouse) were randomly divided into experimental group and control group. Each mouse was infected with 200 µL Pseudomonas aeruginosa injecting into the tail vein, and 400 µL fresh (storage >14 d) and stored RBCs (storage 0.05). F4/80 of experimental group and control group 2, 4 and 8 hours after RBCs infused were 1.83±0.11 vs 0.75±0.06, 0.46±0.06 vs 0.33±0.06 (P0.05), respectively. iNOS, TNF-α, MCP1 of M1 in liver of experimental group and control group 2, 4 and 8 hours after RBCs infused were respectively: iNOS 3.44±0.20 vs 2.46±0.08, 9.25±0.55 vs 2.67±0.12, 2.80±0.08 vs 2.39 ±0.01; TNF-α 1.69±0.22 vs 1.13±0.03, 1.44±0.24 vs 0.96±0.09, 1.31±0.05 vs 0.96±0.06; MCP1 4.96±0.08 vs 4.28±0.27, 4.63±0.04 vs 2.07±0.09, 2.28±0.19 vs 1.33±0.03 (P0.05). 【Conclusion】 Stored RBCs infusion can greatly promote the M1 polarization of BMDMs in liver.
ABSTRACT
【Objective】 To explore the perioperative blood management in patients with pancreatic pseudocyst combiend with coagulation factor Ⅴ(FⅤ) deficiency. 【Methods】 Preoperative: In order to determine the effect of cryoprecipitated antihemophilic factor and fresh frozen plasma (FFP) on the elevation level of factor Ⅴ, we alternately infused cryoprecipitate and FFP in the resting state. TEG, coagulation function and coagulation factor activity were monitored before and 1 h, 24 h and 48 h after infusion, and intraoperative and postoperative blood transfusion strategies were formulated. FFP 600 mL and cryoprecipitate 10 U were supplemented preoperatively. Intraoperative: The operation procedure was performed for 7 hours with an infusion of 600 mL FFP without significant bleeding. Postoperative: FFP was infused. 【Results】 Preoperative: The coagulation factor Ⅴ activity on pre-operation was 1.9% and 1.8%. After alternating infusion cryoprecipitate 10 U and FFP 1 200 mL, the FⅤactivity increased to 5.1% and 6.0%, respectively. There was no significant difference in TEG parameters, PT and ATPP results were decreased to varying degrees. Intraoperative: The operation was successful without obvious bleeding. Postoperative: FFP 500 mL was infused 2 h after operation, and FFP 250-500 mL was injected daily from 1 to 7 days after surgery. No significant bleeding was observed in the wound, the results of TEG, PT, APTT and hemoglobin (Hb) did not change significantly compared with those before surgery. The patient was discharged successfully 12 days after surgery. The genetic test results showed that he had inherited coagulation factor Ⅴ deficiency, which was a compound heterozygous variation. 【Conclusion】 Perioperative blood management in patients with FⅤ deficiency combined with surgical disease, requiring pre-transfusion evaluation and post-transfusion evaluation in combination with laboratory investigations and clinical manifestations, cryoprecipitate and fresh frozen plasma can be effective in supplementing coagulation factors. The TEG seems to be better than the Seven items of coagulation function in judging the clotting status of patients with FⅤ deficiency.
ABSTRACT
Objective @# To investigate the application of indocyanine green in near-infrared fluorescence imaging to determine the scope of necrotic bone resection in osteoradionecrosis of the jaw and to provide a reference for clinicians@*Methods @#Eight patients with osteoradionecrosis of the jaws were enrolled. Indocyanine green was intravenously injected through the elbow vein 10 minutes before osteotomy. After conservative resection of necrotic bone lesions based on imaging results, the scope of potential dead bone resection in the area of low fluorescence intensity was gradually expanded at an initial distance of 0.3 cm. Near-infrared fluorescence imaging and fluorescence intensity determination of bone cross-section were performed before and after extended resection. Statistical differences were analyzed. All patients with osteonecrosis underwent regular follow-up to evaluate the postoperative efficacy@*Results@#Indocyanine green was injected into all 8 patients with osteoradionecrosis for near-infrared fluorescence imaging and the scans were clear; the fluorescence intensity of fresh bone wounds with an expanded mandibular resection range of (0.95 ± 0.14) cm was (226.2 ± 15.8) au, which was higher than that based on intraoperative macroscopic observation and radiological results (108.8 ± 3.4) au, (t = 20.718, P<0.001). The postoperative follow-up improvement rate of 8 patients was 87.5%.@* Conclusion @#Near-infrared fluorescence imaging with indocyanine green can assist in the successful removal of necrotic bone until fresh bleeding of the jaw wound occurs, which has important clinical value in defining the resection range of osteoradionecrosis of the jaw.

Consuming a high-fat diet causes a harmful accumulation of fat in the liver, which may not reverse even after switching to a healthier diet. Different reports dealt with the role of purslane as an extract against high-fat diet; meanwhile, it was necessary to study the potential role of fresh purslane as a hypolipidemic agent. This study is supposed to investigate further the potential mechanism in the hypolipidemic effect of fresh purslane, by measuring cholesterol 7a-hydroxylase (CYP7A1) and low-density lipoprotein receptor (Ldlr). Rats were divided into two main groups: the first one is the normal control group (n=7 rats) and the second group (n=28 rats) received a high fat diet for 28 weeks to induce obesity. Then the high fat diet group was divided into equal four subgroups. As, the positive control group still fed on a high fat diet only. Meanwhile, the other three groups were received high-fat diet supplemented with a different percent of fresh purslane (25, 50 and 75%) respectively. At the end of the experiment, rats were sacrificed and samples were collected for molecular, biochemical, and histological studies. Current study reported that, supplementation of fresh purslane especially at a concentration of 75% play an important role against harmful effects of high-fat diet at both cellular and organ level, by increasing CYP7A1 as well as Ldlr mRNA expression. Also, there were an improvement on the tested liver functions, thyroid hormones, and lipid profile. Fresh purslane plays the potential role as a hypolipidemic agent via modulation of both Ldlr and Cyp7A, which will point to use fresh purslane against harmful effects of obesity.

Enquanto isso, os outros três grupos receberam dieta rica em gordura suplementada com diferentes porcentagens de beldroegas frescas (25%, 50% e 75%), respectivamente. Ao final do experimento, os ratos foram sacrificados e amostras coletadas para estudos moleculares, bioquímica e histológicos. O estudo atual relatou que a suplementação de beldroegas frescas, especialmente a uma concentração de 75%, desempenha papel importante contra os efeitos prejudiciais da dieta rica em gordura em nível celular e orgânico, aumentando a expressão de CYP7A1 e Ldlr mRNA. Além disso, houve melhora nas funções hepáticas testadas, nos hormônios tireoidianos e no perfil lipídico. Beldroegas frescas desempenham papel potencial como agente hipolipemiante por meio da modulação de Ldlr e Cyp7A, o que apontará para o uso de beldroegas frescas contra os efeitos nocivos da obesidade.

Fresh purslane plays the potential role as a hypolipidemic agent via modulation of both Ldlr and Cyp7A, which will point to use fresh purslane against harmful effects of obesity.
Resumo O consumo de uma dieta rica em gordura causa um acúmulo prejudicial de gordura no fígado, que pode não reverter mesmo após a mudança para uma dieta mais saudável. Diferentes relatórios trataram do papel da beldroega como um extrato contra uma dieta rica em gordura; entretanto, foi necessário estudar o papel potencial da beldroega fresca como agente hipolipemiante. Este estudo pretende investigar mais profundamente o mecanismo potencial no efeito hipolipidêmico da beldroega fresca, medindo o colesterol 7a-hidroxilase (CYP7A1) e o receptor de lipoproteína de baixa densidade (Ldlr). Os ratos foram divididos em dois grupos principais: o primeiro é o grupo controle normal (n = 7 ratos) e o segundo grupo (n = 28 ratos) recebeu dieta rica em gorduras por 28 semanas para induzir a obesidade. Em seguida, o grupo de dieta rica em gordura foi dividido em quatro subgrupos iguais. Como, o grupo de controle positivo ainda se alimentava apenas com dieta rica em gordura. Enquanto isso, os outros três grupos receberam dieta rica em gordura suplementada com diferentes porcentagens de beldroegas frescas (25%, 50% e 75%), respectivamente. Ao final do experimento, os ratos foram sacrificados e amostras coletadas para estudos moleculares, bioquímica e histológicos. O estudo atual relatou que a suplementação de beldroegas frescas, especialmente a uma concentração de 75%, desempenha papel importante contra os efeitos prejudiciais da dieta rica em gordura em nível celular e orgânico, aumentando a expressão de CYP7A1 e Ldlr mRNA. Além disso, houve melhora nas funções hepáticas testadas, nos hormônios tireoidianos e no perfil lipídico. Beldroegas frescas desempenham papel potencial como agente hipolipemiante por meio da modulação de Ldlr e Cyp7A, o que apontará para o uso de beldroegas frescas contra os efeitos nocivos da obesidade.

Introduction: Ready-to-eat minimally processed vegetables (RTE-MPV) are vegetables subjected to several steps that modify their natural structure, while maintaining the same freshness and nutritional quality as the fresh produce. Since these products are sold in packages, they must be labeled, even though nutritional labeling is optional. Objective: The goal of this study was to assess the labeling aspects of several brands of RTE-MPV sold in Brazil, determining whether manufacturers adhered to the different types of food labeling legislation. Method: Photographic records of RTE-MPV packages were obtained in different regions of Brazil between October 2020 and August 2021, and labels were analyzed using a checklist that was prepared according to the different types of Brazilian food labeling legislation in force at the time of the study: RDC nº 259/2002, RDC nº 359/2003, RDC nº 360/2003 and Law nº 10,674/2003. Results: The labels of 288 RTE-MPV packages, belonging to 39 brands, were analyzed. Among these, 31 brands showed at least one aspect that was not in accordance with the legislation, such as the lack of information about place of origin, and the presence or absence of gluten. Although optional, most brands (38) adopted nutritional labeling, but the information was incomplete in ten of them. Conclusion: These data indicate that there are flaws in the labeling of RTE-MPV in Brazil, emphasizing the need for manufacturers to comply with the legislation. Moreover, the optional adoption of nutritional labeling by most brands is significantly important for consumers to have additional information about what they consume. (AU)
Introdução: Os vegetais minimamente processados (VMP) são submetidos a etapas que modificam sua estrutura natural, mantendo o frescor e qualidade nutricional dos produtos frescos. Por serem comercializados embalados, esses produtos devem ser rotulados, embora a rotulagem nutricional seja opcional. Objetivo: Este estudo analisou a rotulagem de diferentes marcas de VMP comercializados no Brasil, a fim de determinar a aderência dos produtores às legislações relativas à rotulagem de alimentos. Método: Foram obtidos registros fotográficos de embalagens VMP comercializados em diferentes regiões do Brasil entre outubro de 2020 e agosto de 2021, e os rótulos foram analisados por meio de um checklist elaborado com base nas legislações brasileiras de rotulagem de alimentos vigentes no período em que o estudo foi realizado: RDC nº 259/2002, RDC nº 359/2003, RDC nº 360/2003 e Lei nº 10.674/2003. Resultados: Foram analisados os rótulos de 288 embalagens de VMP, pertencentes a 39 marcas. Dentre essas, 31 marcas apresentaram pelo menos um item que não estava de acordo com as legislações de rotulagem vigentes, como falta de informação sobre o local de origem e a presença ou ausência de glúten. Apesar de opcional, a maioria das marcas (38) adotou a rotulagem nutricional, mas em dez delas as informações estavam incompletas. Conclusão: Esses dados indicam falhas na rotulagem de VMP no Brasil, enfatizando a necessidade das empresas de cumprirem essas regulamentações. Além disso, a adoção opcional da rotulagem nutricional pela maioria das marcas tem grande importância, pois fornece informações adicionais aos consumidores sobre os produtos que consomem. (AU)
ABSTRACT
To study the physical properties of biomaterials like bony hard tissues through the propagation of elastic waves is one of the most successful method.With the help of internal friction measurement, we can study the processes such as recrystallization, annealing, quenching and tempering, plastic deformation and strain ageing. In the present investigation we calculate and -1 reported the internal friction loss (Q ) for all the six types of bovine compact bones for the first time in a single experiment by using the ultrasonic piezoelectric composite oscillator technique with the help of X-cut crystal in different physiological conditions. Significant variation is observed from bone to bone. This may be attributed to composition and mineral content of the bones. Peak temperature data also is also determined. Temperature variation of logarithmic decrement in X-cut quartz transducer is also verified with mounting of bovine compact bar shaped bone -1 samples. Change of internal friction (Q ) with temperature is also calculated to predict the mechanism of acoustic losses and phase transitions in these bony hard tissues. Internal friction measurements are also useful to obtain the information about imperfections in bony hard tissues. The present investigation constitutes a step towards the application of natural bovine bone ceramic materials for the transducer applications
ABSTRACT
Pediatric acute liver failure(PALF)is a severe liver damage caused by multiple factors, resulting in severe impairment of hepatic synthesis, excretion, detoxification and biotransformation.It was thought that PALF patients had coagulation disorders that predisposed them to bleeding.Now it is noted that due to the simultaneous reduction of anticoagulant and procoagulant factors, the body is in a state of rebalanced hemostasis.The risk of thrombosis is nearly equal to hemorrhage.Appropriate laboratory tests can better assess the coagulation status of children with PALF and guide appropriate blood product transfusions to improve coagulation and reduce the risk of transfusion-related fluid overload and other adverse prognosis.
