Fritillaria taipaiensis P.Y.Li is a widely used medicinal herb in treating pulmonary diseases.In recent years,its wild resources have become scarce,and the demand for efficient artificial cultivation has significantly increased.This article is the first to apply phosphate solubilizing bacteria isolated from the rhizosphere soil of F.taipaiensis P.Y.Li to the cultivation process of F.taipaiensis P.Y.Li.The aim is to identify suitable reference strains for the artificial cultivation and industrial development of F.taipaiensis P.Y.Li by examining the effects of various phosphate solubilizing bacteria and their combinations on photosynthesis,physiological and biochemical properties,and gene expression related to the protective enzyme system in F.taipaiensis P.Y.Li.The experiment,conducted in pots at room temperature,included a control group(CK)and groups inoculated with inorganic phosphorussolubilizing bacteria:W1(Bacillus cereus),W2(Serratia plymuthica),W12(Bacillus cereus and Serratia plymuthica),and groups inoculated with organophosphorus-solubilizing bacteria:Y1(Bacillus cereus),Y2(Bacillus cereus),Y12(Bacillus cereus and Bacillus cereus),totaling seven groups.Compared to CK,most growth indices in the bacterial addition groups showed significant differences,with W12 achieving the highest values in all indices except the leaf area index.The content of photosynthetic pigments,photosynthetic parameters,and osmoregulatory substances increased variably in each bacterial treatment group.W12 exhibited the highest content of chlorophyll a and soluble protein,while W1 had the highest free proline content.The activities of peroxidase(POD),superoxide dismutase(SOD),and catalase(CAT)in all inoculated groups were higher than in CK,with significant changes in SOD and CAT activities.The malondialdehyde(MDA)content in all inoculated groups was lower than in CK,with Y12 being the lowest,at approximately 30%of CK.Gene expression corresponding to these three enzymes also increased variably,with POD expression in Y2 being the highest at 2.73 times that of CK.SOD and CAT expression in Y12 were the highest,at 1.84 and 4.39 times that of CK,respectively.These results indicate that inoculating phosphate solubilizing bacteria can enhance the growth of F.taipaiensis P.Y.Li,with the mixed inoculation groups W12 and Y12 demonstrating superior effects.This lays a theoretical foundation for selecting bacterial fertilizers in the cultivation process of F.taipaiensis P.Y.Li. 展开更多

BACKGROUND The incidence of chronic kidney disease(CKD)has dramatically increased in recent years,with significant impacts on patient mortality rates.Previous studies have identified multiple risk factors for CKD,but they mostly relied on the use of traditional statistical methods such as logistic regression and only focused on a few risk factors.AIM To determine factors that can be used to identify subjects with a low estimated glomerular filtration rate(L-eGFR<60 mL/min per 1.73 m^(2))in a cohort of 1236 Chinese people aged over 65.METHODS Twenty risk factors were divided into three models.Model 1 consisted of demographic and biochemistry data.Model 2 added lifestyle data to Model 1,and Model 3 added inflammatory markers to Model 2.Five machine learning methods were used:Multivariate adaptive regression splines,eXtreme Gradient Boosting,stochastic gradient boosting,Light Gradient Boosting Machine,and Categorical Features+Gradient Boosting.Evaluation criteria included accuracy,sensitivity,specificity,area under the receiver operating characteristic curve(AUC),F-1 score,and balanced accuracy.RESULTS A trend of increasing AUC of each was observed from Model 1 to Model 3 and reached statistical significance.Model 3 selected uric acid as the most important risk factor,followed by age,hemoglobin(Hb),body mass index(BMI),sport hours,and systolic blood pressure(SBP).CONCLUSION Among all the risk factors including demographic,biochemistry,and lifestyle risk factors,along with inflammation markers,UA is the most important risk factor to identify L-eGFR,followed by age,Hb,BMI,sport hours,and SBP in a cohort of elderly Chinese people. 展开更多

Aim: To evaluate whether the study of seminal germ cell morphology (SGCM) and semen biochemistry could befruitfully utilized for the diagnosis and management of azoospermic subjects. Methods: In the semen, mature andimmature germ cells are contributed by the testes, 70% of glycerylphosphoryl choline (GPC) by the epididymis, fruc-tose mostly or solely by the seminal vesicles and acid phosphate (ACP) by the prostate. In 16 normal volunteers, 12vasectomized subjects and 186 azoospennic subjects, these parameters have been studied and the data have been ana-lyzed. Results: Both mature and immature germ cells are absent in the semen of vasectomized subjects as well as inobstructive azoospennia; GPC level is also significantly decreased in both these groups. In cases with non-obstructiveazoospermia immature germ cells are present and seminal GPC, ACP and fructose levels are normal. The diagnosis ofobstructive and non-obstructive azoospermia based on these parameters correlated well with 'correct' testicular biopsyfindings. In some cases of azoospermia due to hypospermatogenesis or spermatogenic developmental arrest, the SGCMstudies were very helpful in objectively monitoring the response of the germinal tissue to specific treaunents. Conclu-sion: SGCM and semen biochemical parameters are very valuable non-invasive markers for differentiating obstructivefrom non-obstructive azoospermia. The SGCM findings serve as a dependable non-invasive testicular marker with highpredictive value. (Asian J Androl 2001 Mar; 3: 55-62) 展开更多

Methods: Liver biopsies were performed in 67 pa- tients with hepatitis. The sections were stained with hematoxylin eosin and immunohistochemical stain. Staging of hepatic fibrosis was made microscopically. The serum levels of hyaluronic acid (HA), type Ⅲ procollagen (PC-Ⅲ), laminin (LN), and type Ⅳ collagen (Ⅳ-C) were measured by radioimmunoas- say. Results: The serum levels of HA, PC-Ⅲ, LN and Ⅳ-C were elevated from S1 to S4 because of the in- crease of hepatic fibrosis. The serum concentrations of HA, PC-Ⅲ, LN and Ⅳ-C were increased with the progress of disease, with the highest concentration at the stage of cirrhosis. Conclusion: The stages of hepatic fibrosis are corre- lated with the serum levels of HA, PC-Ⅲ, LN and Ⅳ-C, which as markers may play a role in detecting the degree of hepatic fibrosis. 展开更多

To examine the effect of Gankang Suppository on duck hepatitis B virus (DHBV), the serum biochemistry and hepatic histology in an animal model of DHBV infection, a model of DHBV infection was established by infecting 1-day-old Yingtaogu ducklings with DHBV-positive serum. The successful model was confirmed by PCR assay and 48 ducklings infected with DHBV were randomly divided into 3 groups: a Gankang Suppository treatment group, an acyclovir (ACV) group and a DHBV model group (control), with each group having 16 animals. All the animals were given the medicines for 4 weeks in a row. The serum of the animals was taken 14 and 28 days after the medica- tion and 7 days after drug discontinuation. Real-time PCR was performed to detect the copy numbers of DHBV DNA in the serum. ALT and AST were dynamically monitored. The ducklings were sacrificed on the 7th day after the discontinuation of the treatment and livers were harvested and examined for inflammation and degeneration of liver cells by using HE staining. The results showed that on day 14, 28 after the treatment and day 7 after the withdrawal, the logarithmic values (log) of DHBV DNA copy numbers in ducklings of Gankang Suppository treatment group were significantly lower than that before the treatment (P=0.0092, P=0.0070, P=0.0080, respectively). Compared with DHBV model control group, the ALT level was significantly decreased (P=0.0020, P=0.0019, respectively) on day 28 after the treatment and on day 7 after the withdrawal. The AST level was also reduced on day 14 after the treatment (P=0.0298). Compared with the ACV control group, the level of ALT was lower on day 7 after the withdrawal (P=0.0016). Histologically, the hepatocyte swelling, vacuolous degeneration and acidophilic degeneration in Gankang Suppository treatment group were alleviated 7 days after the withdrawal as compared with model control group (P=0.0282, P=0.0084, P=0.0195, respectively). It is concluded that Gankang Suppository can effectively suppress DHBV replication, reduce the levels of serum ALT and AST and improve hepatic histology. 展开更多

Melanization/pigmentation is an important physiological phenomenon in insects,which is involved incuticular tanning,parasite encapsulation,and egg shell hardening.During the past few years,we have beenusing mosquito eggs as a model to study the detailed biochemistry of melanization reactions in mosquitoes.Chorion of newly oviposited eggs is white and soft,but the chorion becomes black and hard within 3~4 hfollowing oviposition. Once the chorion turns black,the eggs become resistant to desiccation and solubiliza-tion.Floodwater mosquitoes,such as Aedes aegypti,oviposit on substrates at the edge of water and theeggs hatch only after being flooded with water following adequate rainfall.Consequently,the ability towithstand the desiccation and other environmental adversities is critical for egg survival.Our research deal-ing with chorion melanization in mosquitoes is aimed at understanding the biochemical processes and mech- 展开更多

Background: Anesthetic agents are commonly utilized in the handling of non‐human primates for prevent the stress caused in physical exploration or physical restrain. For this reason, the objective of this work was to describe the effect of age and dissociative anesthetics (ketamine and tiletamine), and their combinations with acepromazine, xylazine and zolazepam, on the physiological and blood biochemical parameters in Macaca mulatta. Methods: Eighty male Macaca mulatta were divided into four experimental groups depending on the anesthetic mixture applied. Each group of 20 males was divided into five sub‐groups according to age. Physiological parameters were recorded every five minutes during a 30‐minute period. A blood sample was drawn to analyze blood biochemistry. Results: Statistical analyses revealed significant differences in the physiological parameters between the ketamine‐acepromazine and ketamine‐xylazine groups compared to the control group. The analysis of blood biochemistry found significant differences by age and by anesthetic mixture among all groups. Conclusion: These findings contribute to standardizing this animal model in biological research. 展开更多

In searching for new sources of oil, protein and gelatin researchers have investigated many wild plants, but our research group took a different approach: We looked at insects as oil, protein and gelatin source for both nutritional and industrial applications. According to Sudanese indigenous knowledge, many insects have food and medicinal uses. We targeted two of these insects for our research:Aspongopus vidiuatus(melon bug) and Agonoscelis pubescens(sorghum bug). The two insects showed 27.0% and 28.2% crude protein, 45% and 60% oil, respectively. The oils contained 46.5% and 40.9% oleic acid, 3.4% and 34.5% linoleic acid, 44.2% and 12.1% palmitic acid and traces of linolenic acid,respectively. The tocopherol content of theseoils amounted to 0.3 and 34.0 mg/100g oil, respectively. The total content of sterols in the two oils was 17 and 450 mg/100g oil, respectively, whereasβ-sitosterol was determined as the main compound in all oils with about 60% of the totalsterol. The oxidative stability of the oils, asmeasured by the Rancimat test at 120&#176;C, was 38 and 5.1 h, respectively. Edible gelatin was extracted from the two insect using hot water and mild acid and distilled water. SDS-PAGE patterns ofthe insect gelatins had very low molecularweight chains, and the two gelatins contained 40 kDa asmain component, differential scanning calorimetry results confirmed the difference betweenextraction methods concerning the extracted gelatin quality. FTIR spectra of melon and sorghum bug gelatins were similar and the absorption bands were situated in more than 6 bands in melon bug gelatin and only 6 bands in sorghum bug gelatin. Microstructures of the insect gelatinexamined with the scanning electron microscope showed that melon bug exhibited the finest gelatin network with very small voids. Melon bug gelatin showed the finer structure with smallerprotein strands and voids than sorghum buggelatin. Ice cream was made by using 0.5% insect’sgelatine and compared with that made using 0.5%commercial gelatine as stabilizing agent. The properties of the obtained ice cream produced using insects gelatine were found to be acceptable for the panelists, and no significant differences between ice cream made using insect gelatine when compared with that made using commercial gelatine in their general preferences The behavior of the crude Sorghum bug oil during deep-frying of par-fried potatoes was studied with regard to chemical, physical, and sensory parameters, such as the content ofFFA, tocopherols, polar compounds, oligomerTG, volatile compounds, oxidative stability, and totaloxidation (TOTOX) value. The results showed that the oil was suitable for deep-frying of potatoes. The oxidative stability of sunflower kernel oil was improved by blending with melon bug oil, the oxidative stability in the Rancimat test was improved from 5% to 68% compared to the control, with increasing parts of MBO, respectively. The insect oils were transesterified using methanol or ethanol in the presence of sulfuricacid to obtain biodiesel. The obtained insectbiodiesel characteristics were studied in accordance with the DIN EN 14214 specifications for biodiesel. It was possible to prepare the methyl and ethyl esters catalyzed by H2SO4 from the two insect oils. 展开更多

Salmonellosis is a serious medical and veterinary problem worldwide and causes great concern in the food and livestock industries, especially the poultry industry which occupies a prominent position in the provision of animal protein and accounts for about 25% of local meat production in Nigeria particularly and is identified as a disease of major economic importance causing low performance in poultry production. The study was carried out at the experimental animal farm, Faculty of Veterinary Medicine, University of Nigeria, Nsukka, Nigeria. One hundred (100) five-week old chickens obtained from the Poultry division of National Veterinary Research Institute, Vom, were used for the experiment. The birds were randomly assigned to 4 groups of 25 birds per group (A, B, C, D). Each bird in all the groups received 0.5 ml of PBS containing 1 × 108 cfu/ml of Salmonella enterica serovar Zega as follows: Group A was infected with Salmonella Zega intra-nasally (IN). Group B was infected with Salmonella Zega intra-peritonealy (IP). Group C was infected with Salmonella Zega orally (OR). Group D was the Uninfected control (CT). There was a significant change (p 0.05) in the mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) in the infected groups compared across the different days post infection. There was significant increase (p Salmonella Pullorum and Salmonella Gallinarum that are known to cause pathology in birds Salmonella Zega which is none host specific for birds can also cause pathology in them.

Objective: To compile nursing undergraduates' opinions and suggestions for biochemistry textbook to improve the readability and applicability of a textbook of biochemistry. Methods: This investigation involved 279 nursing undergraduates through delivery of a self-made questionnaire, which was to be used to analyze and study the students' suggestions and opinions on the content of the biochemistry textbook. Results: The investigation revealed that the textbook's difficulty was associated negatively with stu- dents' interest (P 〈 0.05), and the textbook's importance was associated positively with students' interest (P 〈 0.05). Students suggested that the textbook should be closely related to nursing. The contents, difficulty, structure and charts of the textbook should be adjusted properly. Conclusions: The content of the nursing version of the biochemistry textbook should be driven by the needs of the nursing major and should focus on simplifying the textbook's content, and making it practical. This will make the textbook vivid and readable, enhancing the interest of students to accept and benefit from the textbook. 展开更多

Magnetic sense,or termed magnetoreception,has evolved in a broad range of taxa within the animal kingdom to facilitate orientation and navigation.MagRs,highly conserved A-type iron-sulfur proteins,are widely distributed across all phyla and play essential roles in both magnetoreception and iron-sulfur cluster biogenesis.However,the evolutionary origins and functional diversification of MagRs from their prokaryotic ancestor remain unclear.In this study,MagR sequences from 131 species,ranging from bacteria to humans,were selected for analysis,with 23 representative sequences covering species from prokaryotes to Mollusca,Arthropoda,Osteichthyes,Reptilia,Aves,and mammals chosen for protein expression and purification.Biochemical studies revealed a gradual increase in total iron content in MagRs during evolution.Three types of MagRs were identified,each with distinct iron and/or iron-sulfur cluster binding capacity and protein stability,indicating continuous expansion of the functional roles of MagRs during speciation and evolution.This evolutionary biochemical study provides valuable insights into how evolution shapes the physical and chemical properties of biological molecules such as MagRs and how these properties influence the evolutionary trajectories of MagRs. 展开更多

This study aimed to examine the effects of inoculating Fritillaria taipaiensis P.Y.Li leaves with different strains ofpotassium-solubilizing bacteria (KSB), or combinations thereof, focusing on aspects of photosynthesis and physiologicaland biochemical characteristics. At present, some studies have only studied the rhizosphere microbialcommunity characteristics of F. taipaiensis and have not discussed the effects of different microbial species on thegrowth promotion of F. taipaiensis. This paper will start from the perspective of potassium-solubilizing bacteria toconduct an in-depth study. Seed cultivation commenced at the base with three different KSBs in early October2022. The growth of F. taipaiensis leaves was observed after different treatments. Both single-plant and compoundinoculations were executed. A total of eight treatment groups were established, with aseptic fertilizer and sterilizedsoil functioning as the control group. The results reveal that intercellular CO_(2) concentration (Ci), stomatal conductance(Gs), and transpiration rate (Tr) were at their apex in the S7 group. Most treatment groups exhibited anincrease in leaf area, photosynthetic pigment content, soluble sugar, soluble protein, Superoxide Dismutase(SOD), Peroxidase (POD), Catalase (CAT) activities, and proline content. The expression levels of POD, SOD,and CAT genes were evaluated, following inoculation with different KSB. The highest was the S7 group. Theinoculation with various KSB, or combinations thereof, appears to bolster the growth and development of F. taipaiensis.The composite inoculation group S7, comprising Bacillus cereus, Burkholderia cepacia, and Bacillus subtilis,manifested the most favorable impact on the diverse indices of F. taipaiensis, thereby furnishing valuableinsights for the selection of bacterial fertilizer in the artificial cultivation of F. taipaiensis. 展开更多

The purpose of this study is to investigate the physicochemical properties of some local varieties of onion (Allium cepa L.) and compare them with an imported variety, all collected in May 2021. Proteins, reducing sugars, lipids, and polyphenol content were estimated according to the AFNOR standardized methods. The determination of calcium, magnesium, iron, sodium, potassium and phosphorus was performed by atomic absorption spectrophotometer coupled with a CCD detector. The results highlighted an average acidity of 0.377% ± 0.002% lower than the value of the imported variety which is 0.520% ± 0.001%. Local varieties have a pH ranging from 6.35 ± 0.003 to 6.42 ± 0.004, while the variety has a pH of 6.36 ± 0.003. The ash and dry matter contents vary respectively from 4.788% ± 0.004% to 8.253% ± 0.003% and 7.945% ± 0.021% to 11.945% ± 0.007% for the local varieties. Moreover, the imported one has ash and dry matter contents of 5.175% ± 0.007% and 10.035% ± 0.021% respectively. The results show that the protein, reducing sugar and lipid contents in the local onion varieties vary respectively from 2.815 ± 0.000 to 15.634 ± 0.001 g·100 g<sup>-1</sup>;4.691 ± 0.001 to 12.596 ± 0.002 g·100 g<sup>-1</sup> and 0.006 ± 0.001 to 0.050 ± 0.057 g·100 g<sup>-1</sup>. Furthermore, the imported variety has a protein, reducing sugar and lipid content of 5.649 ± 0.002;8.565 ± 0.002 g·100 g<sup>-1</sup> and 0.011 ± 0.010 g·100 g<sup>-1</sup> respectively. The maximum levels of total polyphenols are obtained in the imported variety, Bellani and Gandiol, respectively 9.973 ± 0.001, 4.535 ± 0.002, and 3.425 ± 0.006 mg EAG/g of dry matter. The local varieties have a significant calorific intake of between 35.451 ± 0.001 and 112.980 ± 0.003 kcal·100 g<sup>-1</sup> compared to the imported one with an energy value of 56.953 ± 0.001 kcal·100 g<sup>-1</sup> of dry matter. The bulbs of different onion varieties studied have a fairly high content of mineral elements. The potassium content of local varieties is between 502.16 ± 0.06 mg·100 g<sup>-1</sup> and 582.77 ± 0.04 mg·100 g<sup>-1</sup> while the imported variety has a content of 536.62 ± 1.30 mg·100 g<sup>-1</sup>. They note that the local varieties have a better calcium content (249.75 ± 0.07 to 434.20 ± 0.57 mg·100 g<sup>-1</sup>) and magnesium (142.15 ± 0.07 to 162.60 ± 0.42 mg·100 g<sup>-1</sup>) than the imported variety (229.58 ± 0.04 mg·100 g<sup>-1</sup>) except for the varieties White Grano (228.29 ± 0.01 mg·100 g<sup>-1</sup>) and Rouge Amposta (117.00 ± 0.42 mg·100 g<sup>-1</sup>) respectively. These results reveal that Gandiol, Dayo and Orient F1 are nutritionally found better due to their higher antioxidant property, proteins, carbohydrates, and reducing sugar and should be included in diets to supplement our daily allowance needed by the body. 展开更多
