The focus of this research is to know the effect of tariff policy of automobile demand before and after World Trade Organization (WTO). Analysis method used in this research is quantitative analysis with simultaneous model and estimated using Two Stage Least Square (TSLS) approach, and the next analysis is a test of hypothesis using partial and simultaneous test. Based on the result of the estimation, it can be concluded that the independent variable in the first model, car price and PDB per capita is positive and dummy variable of economic crisis is negative to Japanese automobile demand. And independent variable in the second model, demand and tariff (the first dummy) is positive but fuel price and tariff (the second and the third dummy) are negative to Japanese automobile price. In other words, the influence of tariff policy in 1980-1994 is positive, and those in 1995-1997 and 1998-2005 are negative to Japanese automobile demand. 展开更多

AIM To determine the effects of implementing an enteral feeding protocol on the nutritional delivery and outcomes of intensive care patients.METHODS An uncontrolled, observational before-and-after study was performed in a tertiary mixed medical-surgical intensive care unit(ICU). In 2013, a nurse-driven enteral feeding protocol was developed and implemented in the ICU. Nutrition and outcome-related data from patients who were treated in the study unit from 2011-2012(the Before group) and 2014-2015(the After group) were obtained from a local electronic database, the national Population Registry and the hospital's Infection ControlService. Data from adult patients, readmissions excluded, who were treated for at least 7 d in the study unit were analysed. RESULTS In total, 231 patients were enrolled in the Before and 249 in the After group. The groups were comparable regarding demographics, patient profile, and severity of illness. Fewer patients were mechanically ventilated on admission in the After group(86.7% vs 93.1% in the Before group, P = 0.021). The prevalence of hospitalacquired infections, length of ICU stay and ICU, 30-and 60-d mortality did not differ between the groups. Patients in the After group had a lower 90-d(P = 0.026) and 120-d(P = 0.033) mortality. In the After group, enteral nutrition was prescribed less frequently(P = 0.039) on day 1 but significantly more frequently on all days from day 3. Implementation of the feeding protocol resulted in a higher cumulative amount of enterally(P = 0.049) and a lower cumulative amount of parenterally(P < 0.001) provided calories by day 7, with an overall reduction in caloric provision(P < 0.001). The prevalence of gastrointestinal symptoms was comparable in both groups, as was the frequency of prokinetic use. Underfeeding(total calories < 80% of caloric needs, independent of route) was observed in 59.4% of the study days Before vs 76.9% After(P < 0.001). Inclusion in the Before group, previous abdominal surgery, intraabdominal hypertension and the sum of gastrointestinal symptoms were found to be independent predictors of insufficient enteral nutrition.CONCLUSION The use of a nurse-driven feeding protocol improves the delivery of enteral nutrition in ICU patients without concomitant increases in gastrointestinal symptoms or intra-abdominal hypertension. 展开更多

Local ischemia often causes a series of inflammatory reactions when both brain immune cells and the peripheral immune response are activated.In the human body,the gut and lung are regarded as the key reactional targets that are initiated by brain ischemic attacks.Mucosal microorganisms play an important role in immune regulation and metabolism and affect blood-brain barrier permeability.In addition to the relationship between peripheral organs and central areas and the intestine and lung also interact among each other.Here,we review the molecular and cellular immune mechanisms involved in the pathways of inflammation across the gut-brain axis and lung-brain axis.We found that abnormal intestinal flora,the intestinal microenvironment,lung infection,chronic diseases,and mechanical ventilation can worsen the outcome of ischemic stroke.This review also introduces the influence of the brain on the gut and lungs after stroke,highlighting the bidirectional feedback effect among the gut,lungs,and brain. 展开更多

We theoretically investigated negative entropy S of biopolymer which passes through a nanometer pore(such as a-hemolysin), especially entering process and escaping process, on the basis of which we also studied biopolymer entering-pore time rent, biopolymer entering mean velocity Vent, biopolymer escaping-pore time resc, and biopolymer escaping mean velocity vesc, respectively. Our results illustrate that the entering and escaping processes of biopolymer depend on its negative entropy, and entering process is more difficult than escaping process for biopolymer translocation. This tremendous difference between the two processes will offer a useful engineering hint for single macromolecule identification. 展开更多

Objective:To evaluate relationship between changes in the beneficial bacteria in intensive care unit(ICU)patients and nutritional therapy type.Methods:Ten patients aged≥18 years admitted to the ICU between January and December 2020,were included.Good enteral nutrition was defined as early achievement of target calorie intake through enteral feeding.The ratio of beneficial bacteria at the first and second bowel movements after each patient’s admission was calculated and the patients were classified into the increase or decrease group.Among all patients,five each were in the increase and decrease groups.We investigated patient background,changes in sequential organ failure assessment(SOFA)and acute physiology and chronic health evaluation(APACHE)Ⅱscores,nutritional doses or methods,and clinical outcomes.Results:No relationship was found between changes in the ratio of beneficial bacteria and changes in SOFA/APACHEⅡscores at the time of admission.The rate of good enteral nutrition was significantly higher in the increase group than in the decrease group(4/5 vs.0/5,P=0.01).Conclusions:An increase in beneficial bacteria may be significantly related to the early establishment of enteral nutrition.In the future,accumulating cases may make it possible to establish a new nutritional strategy for critically ill patients from an intestinal microbiota perspective. 展开更多

BACKGROUND Percutaneous endoscopic gastrostomy(PEG)and laparoscopically inserted gastrostomy have become the gold standard for adult patients and children,respectively,requiring long-term enteral nutrition support.Procedure-related mortality is a rare event,often reported to be zero in smaller studies.National data on 30-d mortality and long-term survival rates after gastrostomy placement are scarce in the literature.AIM To study the use of gastrostomies in Sweden from 1998-2019 and to analyze procedure-related mortality and short-term(<30 d)and long-term survival.METHODS In this retrospective,population-based cohort study,individuals that had received a gastrostomy between 1998-2019 in Sweden were included.Individuals were identified in the Swedish National Patient Register,and survival analysis was possible by cross-referencing the Swedish Death Register.The cohort was divided into three age groups:Children(0-18 years);adults(19-64 years);and elderly(≥65 years).Kaplan-Meier with log-rank test and Cox regression were used for survival analysis.RESULTS In total 48682 individuals(52%males,average age 60.9±25.3 years)were identified.The cohort consisted of 12.0%children,29.5%adults,and 58.5%elderly.An increased use of gastrostomies was observed during the study period,from 13.7/100000 to 22.3/100000 individuals(P<0.001).The use of PEG more than doubled(about 800 to 1800/year),with a corresponding decrease in open gastrostomy(about 700 to 340/year).Laparoscopic gastrostomy increased more than ten-fold(about 20 to 240/year).Overall,PEG,open gastrostomy,and laparoscopic gastrostomy constituted 70.0%(n=34060),23.3%(n=11336),and 4.9%(n=2404),respectively.Procedure-related mortality was 0.1%(n=44)overall(PEG:0.05%,open:0.24%,laparoscopic:0.04%).The overall 30-d mortality rate was 10.0%(PEG:9.8%,open:12.4%,laparoscopic:1.7%)and decreased from 11.6%in 1998-2009 vs 8.5%in 2010-2019(P<0.001).One-year and ten-year survival rates for children,adults,and elderly were 93.7%,67.5%,and 42.1%and 79.9%,39.2%,and 6.8%,respectively.The most common causes of death were malignancies and cardiovascular and respiratory diseases.CONCLUSION The annual use of gastrostomies in Sweden increased during the study period,with a shift towards more minimally invasive procedures.Although procedure-related death was rare,the overall 30-d mortality rate was high(10%).To overcome this,we believe that patient selection should be improved. 展开更多

Background Necrotic enteritis(NE)is a major enteric disease in poultry,yet effective mitigation strategies remain elusive.Deoxycholic acid(DCA)and butyrate,two major metabolites derived from the intestinal microbiota,have independently been shown to induce host defense peptide(HDP)synthesis.However,the potential synergy between these two compounds remains unexplored.Methods To investigate the possible synergistic effect between DCA and butyrate in regulating HDP synthesis and barrier function,we treated chicken HD11 macrophage cells and jejunal explants with DCA and sodium butyrate(NaB),either individually or in combination,for 24 h.Subsequently,we performed RNA isolation and reverse transcrip-tion-quantitative PCR to analyze HDP genes as well as the major genes associated with barrier function.To further determine the synergy between DCA and NaB in enhancing NE resistance,we conducted two independent trials with Cobb broiler chicks.In each trial,the diet was supplemented with DCA or NaB on the day-of-hatch,followed by NE induction through sequential challenges with Eimeria maxima and Clostridium perfringens on d 10 and 14,respectively.We recorded animal mortality after infection and assessed intestinal lesions on d 17.The impact of DCA and NaB on the microbiota in the ileum and cecum was evaluated through bacterial 16S rRNA gene sequencing.Results We found that the combination of DCA and NaB synergistically induced multiple HDP genes in both chicken HD11 cells and jejunal explants.Additionally,the gene for claudin-1,a major tight junction protein,also exhibited synergistic induction in response to DCA and NaB.Furthermore,dietary supplementation with a combination of 0.75 g/kg DCA and 1 g/kg NaB led to a significant improvement in animal survival and a reduction in intestinal lesions compared to either compound alone in a chicken model of NE.Notably,the cecal microbiota of NE-infected chickens showed a marked decrease in SCFA-producing bacteria such as Bacteroides,Faecalibacterium,and Cuneatibacter,with lactobacilli becoming the most dominant species.However,supplementation with DCA and NaB largely restored the intestinal microbiota to healthy levels.Conclusions DCA synergizes with NaB to induce HDP and claudin-1 expression and enhance NE resistance,with potential for further development as cost-effective antibiotic alternatives. 展开更多

Background The poultry industry needs effective antibiotic alternatives to control outbreaks of necrotic enteritis(NE)caused by Clostridium perfringens.Methods The aim of this study was to investigate the effects of dietary supplementation with Macleaya cordata extract(MCE)on the immune function and gut microbiota of broilers with NE.A total of 2881-day-old broiler chicks were randomly assigned to a 2×2 factorial arrangement with two concentrations of dietary MCE supplementation(0 or 350 mg/kg of diet)and two disease challenge statuses(control or NE).Results The results revealed that NE significantly increased the feed conversion rate(FCR),mortality,intestinal lesion score,the levels of IL-1β,IL-17 and IFN-γ/IL-4 in serum and IL-17/IL-10 in the jejunal mucosa,m RNA levels of TLR2,IFN-γand p Ig R in the jejunum,and Clostridium perfringens concentrations in the cecum.NE significantly decreased the body weight(BW),body weight gain(BWG),jejunal villus height,V/C,m RNA level of AMPK-α1 in jejunum,IL-4 level in the jejunal mucosa and lactic acid bacteria abundance in the cecum.MCE significantly increased BW,BWG,jejunal villus height,V/C,m RNA levels of occludin,ZO-1 and AMPK-α1 in the jejunum,the levels of Ig A and Ig G in serum and IL-10 in the jejunal mucosa and m RNA levels of NF-κB,IL-10 and MHC-II in the jejunum.Additionally,MCE significantly decreased the FCR,mortality,intestinal lesion score,jejunal crypt depth,the levels of IFN-γand IL-17 in serum and IL-17/IL-10 in the jejunal mucosa,Clostridium perfringens concentrations in the cecum,and m RNA levels of IL-17/IL-10 in the jejunum.Moreover,NE significantly increased the abundance of bacteria that are associated with inflammation,obesity and depression(Alistipes,Barnesiella,Intestinimonas,RF39 and UCG-005)and significantly decreased the abundance of short-chain fatty acid(SCFA)-producing bacteria(Anaerotruncus,Butyricicoccus and Bacteroides)in the cecum.MCE significantly increased the abundance of SCFA-producing bacteria(Streptococcus,Ruminococcus_torques_group and Lachnospiraceae_NK4A136_group)and significantly reduced the abundance of bacteria that are associated with inflammation and obesity(Alistipes,Barnesiella and UCG-010)in the cecum.In the cecum of broilers with NE,the relative abundance of Barnesiella and Alistipes was higher and that of Lachnoclostridium and Shuttleworthia was lower.Interestingly,these trends were reversed by the addition of MCE to the diet.Spearman correlation analysis showed that Barnesiella and Alistipes were associated with enhanced intestinal inflammation and inhibited growth performance,whereas Lachnoclostridium and Shuttleworthia were associated with anti-inflammatory effects.Conclusions MCE ameliorated the loss of growth performance in broiler chickens with NE,probably by regulating the intestinal barrier,immune function,and gut microbiota. 展开更多

Background:This research focuses on herbal medicine,an ancient healthcare practice,exploring the antibacterial attributes of fresh and dried leaf extracts from Momordica charantia(commonly known as Bitter melon)and Vernonia amygdalina(Bitter leaf).The study specifically investigates their effects on different bacterial strains associated with gastroenteritis.Methods:Four enteric bacterial isolates-Klebsiella pneumoniae,Salmonella typhi,Escherichia coli,and Proteus mirabilis-were obtained from the Medical Laboratory Unit at Babcock University Teaching Hospital in Ilishan-Remo,Ogun State.Phytochemical screening and antibacterial testing were conducted using standard biochemical techniques and the Punch-hole agar diffusion method,respectively.Results:Qualitative phytochemical screening of the plant extracts revealed the presence of flavonoids,glycosides,and saponin in both plants,excluding terpenoids.Alkaloids were identified only in Vernonia amygdalina.Despite these phytochemicals,neither plant displayed inhibitory effects on the tested bacterial isolates(Escherichia coli,Proteus mirabilis,Klebsiella pneumoniae,and Salmonella typhi)when tested individually or in combination.Intriguingly,combining the fresh and dried leaf extracts of Momordica charantia and Vernonia amygdalina with a standard drug resulted in smaller mean zone diameters of inhibition(Escherichia coli range:14 mm–16 mm,Proteus mirabilis range:31 mm–35 mm,Klebsiella pneumoniae range:13 mm–22 mm,and Salmonella typhi range:35 mm–38 mm)compared to the drug tested alone(16 mm–45 mm).Conclusion:Despite previous indications of antibacterial properties in various extracts of V.amygdalina and M.charantia leaves,our study presents contradictory results,prompting the need for further investigation despite the presence of significant phytochemicals. 展开更多

Background:Murrah buffalo is a breed of water buffalo(Bubalus bubalis)reared for milk and meat,especially in Northern India.There are so many studies on the antimicrobial potential of the cow(Bos indicus)urine but buffalo urine has rarely been studied.This study was aimed to evaluate the antimicrobial activity in whole buffalo urine and its distillate.Methods:Urine specimens were collected from seven Murrah buffalo heifers in the morning over three days from all seven heifers and distillated to prepare urine distillate(UD).The antimicrobial activity was determined through 96 well microplate method diluting(1:1)urine and UD in Mueller Hinton liquid medium against 919 microbial strains belonging to 148 species of 49 genera(Candia,11 genera of Gram+ve bacteria,37 genera of Gram-ve bacteria).The test strains were taken from the repository,revived and tested for purity before testing.The test strains were of clinical origin(372),environmental origin(496)and also from reference strain repositories(51).Results:Of the 919 test strains,a total of 57.89%and 56.04%of the tested strains were susceptible to UD and urine,respectively.There was a no significant(p>0.4)difference in the antimicrobial activity of UD and urine against 919 strains of microbes,regardless of their genus,species,and Gram staining reaction.Similarly,there was no significant(p>0.4)difference between the susceptibility of bacterial and Candida strains to UD or urine.However,strains of clinical origin were more often resistant to buffalo UD and urine(p<0.01)than strains isolated from environmental sources irrespective of their Gram staining characteristics(p>0.05).A significantly(p<0.01)higher proportion of reference strains was susceptible to UD and urine than microbial strains of clinical and environmental origin.For buffalo urine and UD,the most susceptible strains were Stenotrophomonas maltophilia(13/13)followed by Citrobacter freundii(8/10);Salmonella enterica ssp.enterica(21/27),Geobacillus stearothermophilus(23/30),Staphylococcus aureus(13/17),and Paenibacillus larvae(7/10)strains.The most resistant strains belonged to Acinetobacter calcoaceticus(15/20)species followed by strains of Paenibacillus alvei(11/16),Edwardsiella tarda(20/30),Bacillus megaterium(7/11)and Escherichia coli(59/110)species.There was insignificant(p,>0.05)difference in susceptibility of strains of different species of the same genus;however,among all the Bacillus species strains of B.coagulans were the most susceptible(66.7%)and strains of B.megaterium were the least susceptible(36.4%),similarly Enterococcus faecium strains were more susceptible(68.2%)than strains of Enterococcus faecalis(38.9%),70%strains of P.larvae were susceptible to urine and UD but only 31.3%of strains of P.alvei were susceptible.Strains of Klebsiella pneumoniae and Raoultella terrigena,earlier belonging to the same genus Klebsiella,had comparable susceptibility to buffalo urine and UD.Conclusion:The study concluded that buffalo urine may be a potential antimicrobial and may be explored further for identification of active antimicrobial compounds in buffalo urine. 展开更多
