Multi-protective effects of wheat embryo globulin on D-gal-induced aging mice

Wheat embryo globulin(WEG)has been proven to possess multiple biological activities,including antioxidative properties,immunomodulatory,and so on.Aged mouse model were established by subcutaneous injection of D-galactose(D-gal),and the effects of WEG on learning,memory,and antioxidant capacity in aging mice were explored through behavioural tests and antioxidant enzyme activities determination.Compared with the Model group,WEG improved the percentage of the platform quadrant,increased the number of crossing platforms,and enhanced the identification indexs.WEG also increased total antioxidant capacity(T-AOC),superoxide dismutase(SOD),and glutathione peroxidase(GSH-Px)activities in the liver and brains of aging mice,and reduced malondialdehyde(MDA)content.Pathological observations indicated that WEG protected against damage to brain in D-gal-induced aging mice.These results effectively revealed that WEG not only improved the abilities of learning and memory,and the cognitive impairment,but also delayed the aging process of the D-gal-induced mice.

Anti-thymocyte globulin for treatment of T-cell-mediated allograft rejection

Anti-thymocyte globulin(ATG)is a pivotal immunosuppressive therapy utilized in the management of T-cell-mediated rejection and steroid-resistant rejection among renal transplant recipients.Commercially available as Thymoglobulin(rabbit-derived,Sanofi,United States),ATG-Fresenius S(rabbit-derived),and ATGAM(equine-derived,Pfizer,United States),these formulations share a common mechanism of action centered on their interaction with cell surface markers of immune cells,imparting immunosuppressive effects.Although the prevailing mechanism predominantly involves T-cell depletion via the complement-mediated pathway,alternate mechanisms have been elucidated.Optimal dosing and treatment duration of ATG have exhibited variance across randomised trials and clinical reports,rendering the establishment of standardized guidelines a challenge.The spectrum of risks associated with ATG administration spans from transient adverse effects such as fever,chills,and skin rash in the acute phase to long-term concerns related to immunosuppression,including susceptibility to infections and malignancies.This comprehensive review aims to provide a thorough exploration of the current understanding of ATG,encompassing its mechanism of action,clinical utility in the treatment of acute renal graft rejections,specifically steroid-resistant cases,efficacy in rejection episode reversal,and a synthesis of findings from different eras of maintenance immunosuppression.Additionally,it delves into the adverse effects associated with ATG therapy and its impact on long-term graft function.Furthermore,the review underscores the existing gaps in evidence,particularly in the context of the Banff classification of rejections,and highlights the challenges faced by clinicians when navigating the available literature to strike the optimal balance between the risks and benefits of ATG utilization in renal transplantation.

Effect of intravenous gamma globulin on short- and mid-term clinical outcome in acute viral myocarditis in children

Acute viral myocarditis is an extremely diverse disease with a predictable good outcome with supportive therapy. The objective of this study was to look at the clinical outcome of patients receiving additional intravenous gamma globulin compared to those receiving conventional anti-congestive therapy alone. Patients and methods: This is a retrospective review of charts of children admitted with acute myocarditis. Group 1 was children who received intravenous gamma globulin (IVIG) along with conventional anti-congestive therapy. Group 2 were patients who received the conventional anticongestive therapy alone. Short-term outcome was survival to hospital discharge, and mid-term outcome was improvement of left ventricular ejection fraction at 6 months and one year follow-up. Results: A total of 36 patients were enrolled and 18 were males. The mean age of all patients was 2.3 ± 2.6 years and the mean duration of illness for the whole group was 6.7 ± 3.8 days. Group 1 comprised of 16 patients. There was no difference in short-term outcome with mortality of 2 patients in Group1 (12.5%) and 3(15%) in Group 2 (p = 0.2). At intermediate term follow up, recovery of ejection fraction in Group 1 was in 4/14 (28%) and in Group 2 it was 9/17 (55%) and at 12 months it was 10/13 (77%) in Group 1 and 15/16 (94%) in Group 2 (p = 0.02 and 0.19 respectively). Conclusion: Acute myocarditis has a high spontaneous cure rate. Our study did not show any significant difference in the short-term or midterm outcome between children receiving IVIG compared to those who did not.

Protein Bodies in Cotyledon Cells Exhibit Differential Patterns of Legumin-Like Proteins Mobilization during Seedling Germinating States

Olive (Olea europaea L.) tree is one of the most extensive and important agricultural crop in Mediterranean countries due to its beneficial health and nutritional properties and its high economic value. Currently, olive tree constitutes the sixth most important cultivated plant in the world, spreading from the Mediterranean region of origin to new production areas such as Australia, South and North America and South Africa. However, the mobilization processes of storage materials i.e. reserve proteins during seed germination, which are largely involved in essential physiological process including plant growth and development, remain poorly understood. Morphometric and immunohistochemistry analyses of protein bodies contained in olive seed storage tissues, cotyledon and endosperm, were performed by using different microscopy techniques, including light (bright-field and fluorescence) microscopy and transmission electron microscopy. Furthermore, we used legumin-like proteins (11S-type globulins) as a molecular marker to study the mobilization of reserve proteins from PBs of cotyledons at germinating seedling stages by using immunofluorescence assays. Results demonstrated that cotyledon and endosperm are characterized by distinct PBs populations containing legumin-like proteins, distinctly discriminated by the number of PBs per cell and tissue, size, immunofluorescence and histochemical staining. These features reflect differential PBs biogenesis during development and maturation processes in olive seed tissues endosperm and cotyledon, in relation to proteins (polypeptides) final composition, SSPs processing and/or packaging during seed maturation. Three different mobilization patterns of legumin-like proteins were identified for the first time in cotyledon PBs during seedling germinating process. Mature proteins composition and/or processing, cell types and enzyme composition and/or differential activation have been discussed as key features determining how proteins mobilize from PBs for further degradation in the cotyledon.

Effect of intraperitoneal and intramuscular injection of killed aeromonas hydrophila on lymphocytes and serum proteins of common carp, cyprinus carpio

The effects of injectable killed Aeromonas hydrophila on lymphocyte populations and on serum proteins of juvenile common carp, Cyprinus carpio, were examined. The fishes were injected either intraperitoneally or intramuscularly with killed A. hydrophila bacterin isolated from a diseased fish. 15 days after injection the lymphocyte count was significantly higher in the kidney of intraperitoneally bacteria injected fishes than in the normal saline injected fishes (p 0.05). In the intramuscular bacteria injected fishes in comparison with the normal saline group, the lymphocyte count was significantly higher only in the blood (p 0.05). In comparison between the serum protein parameters in different groups, in intraperitoneal injection of killed-bacteria, total albumin as well as the ratio of albumin/globulin was greater than the control group (p 0.05). In intramuscular injection, the normal saline-injected group, amount of α?-globulin was significantly higher than bacteria-injected group (p 0.05).

Comparative studies on seed protein characteristics in eight lines of two Gossypium species

Background:In order to achieve the targets aiming at the improvement of protein quality,knowledge regarding seed protein fractions and polypeptides constituting them in different crops is essential.Besides having high nutritional value as animal feed and human food,the protein isolates from cottonseed meal have also been proven promising as industrial raw materials for a number of applications.As far as Indian work on the characterization of cotton seed proteins is concerned,relatively meagre reports are available.Keeping in mind the importance of cotton seed proteins,lines belonging to Gossypium arboreum L.(Indian cotton)and G.hirsutum L.(American cotton)which are grown in all the major cotton growing states in India were selected for analysing their seed protein characteristics.Results:Whereas G.arboreum(A-genome)lines revealed a lower range of seed protein content i.e.19.5-24.3%,an upper range(21.8~29.5%)could be observed in lines of G.hirsutum(AD-genome).Globulins represented dominating fraction in both species followed by albumins,glutelins and prolamins.A significant positive correlation between albumins/globulins and seed protein content in G.arboreum/G.hirsutum,respectively,was observed.Intraspecific electrophoretic variation in seed protein extracts was observed in the region of molecular weight 22 kDa-27 kDa in lines of both the species;however some lines with A-genome showed similarity in banding pattern with AD-genome.Four polypeptides with disulphide-linkages were also reported for the first time.Albumins were observed to reveal more variations in their electrophoretic pat-tern between the lines of two species followed by globulins.Conclusion:On the basis of present and previous studies,screening the lines with low or high protein content will lead the selection of lines with superior polypeptide fraction important for nutritional and industrial purposes.On comparing the composition and behaviour of four 2-S linked polypeptides with other plant groups,these were suggested to be legumin-like in nature.The similarity in banding patterns between the lines of A-genome and AD-genome species marked towards the close evolutionary relationship between these two.Albumin fractions on the basis of our results could be taken for cultivar differentiation in cotton crop.

Chronic hepatitis B infection in pregnancy

There are no standard guidelines to follow when a patient with chronic hepatitis B infection becomes pregnant or desires pregnancy. Topics to consider include which patients to treat, when to start treatment, what treatment to use and when to stop treatment. Without any prophylaxis or antiviral therapy, a hepatitis B surface antigen and E antigen positive mother has up to a 90% likelihood of vertical transmission of hepatitis B virus(HBV) to child. Standard of care in the United States to prevent perinatal transmission consists of administration of hepatitis B immune globulin and HBV vaccination to the infant. The two strongest risk factors of mother to child transmission(MTCT) of HBV infection despite immunoprophylaxis are high maternal HBV viral load and high activity of viral replication. The goal is to prevent transmission of HBV at birth by decreasing viral load and/or decreasing activity of the virus. Although it is still somewhat controversial, most evidence shows that starting antivirals in the third trimester is effective in decreasing MTCT without affecting fetal development. There is a growing body of literature supporting the safety and efficacy of antiviral therapies to reduce MTCT of hepatitis B. There are no formal recommendations regarding which agent to choose. Tenofovir, lamivudine and telbivudine have all been proven efficacious in decreasing viral load at birth without known birth defects, but final decision of which antiviral medication to use will have to be determined by physician and patient. The antivirals may be discontinued immediately if patient is breastfeeding, or within first four weeks if infant is being formula fed.

Serum calcium,albumin,globulin and matrix metalloproteinase-9 levels in acute cerebral infarction patients

BACKGROUND Hemorrhagic transformation(HT)is a common complication in patients with cerebral infarction.However,its pathogenesis is poorly understood.The knowledge of factors that may increase risk for HT may help in improving the safety of thrombolytic therapy.AIM To investigate the predictive value of serum calcium,albumin,globulin and matrix metalloproteinase-9(MMP-9)levels for HT after intravenous thrombolysis(IVT)in patients with acute cerebral infarction.METHODS Five hundred patients with acute cerebral infarction who received IVT with alteplase within 4.5 h after the onset of disease between January 2018 and January 2021 at our hospital were selected as the study subjects.They were divided into groups based on computed tomography scan results of the brain made within 36 h after thrombolysis.Forty patients with HT were enrolled in an observation group and 460 patients without HT were enrolled in a control group.Serum calcium,albumin,globulin and MMP-9 levels were compared between the two groups.Regression analysis was used to discuss the relationship between these indices and HT.RESULTS The previous history of hypertension,diabetes,atrial fibrillation,cerebrovascular diseases,smoking and alcohol intake were not associated with HT after IVT in patients with acute cerebral infarction(all P>0.05).The National Institutes of Health stroke scale(NHISS)score was associated with HT after IVT in patients with acute cerebral infarction(P<0.05).The serum calcium and albumin levels were lower in the observation group than in the control group(all P<0.05).The levels of globulin and MMP-9 were significantly higher in the observation group than in the control group(all P<0.05).Logistic regression analysis showed that NHISS score,serum calcium,albumin,globulins and MMP-9 were independent factors influencing the occurrence of HT following IVT in patients with cerebral infarction(P<0.05).CONCLUSION Serum calcium,albumin,globulin and MMP-9 levels are risk factors for HT after IVT in patients with acute cerebral infarction.Moreover,NHISS score can be used as a predictor of post-thrombolytic HT.

High-dose hepatitis B immunoglobulin therapy in hepatocellular carcinoma with hepatitis B virus-DNA/hepatitis B e antigen-positive patients after living donor liver transplantation

AIM: To investigate the impact of high-dose hepatitis B immunoglobulin(HBIG) on hepatocellular carcinoma(HCC) and hepatitis B virus(HBV) recurrence and overall survival after living donor liver transplantation(LDLT).METHODS: We investigated 168 patients who underwent LDLT due to HCC, and who were HBV-DNA/hepatitis B e antigen(HBe Ag)-positive, from January 2008 to December 2013. After assessing whether the patients met the Milan criteria, they were assigned to the low-dose HBIG group and high-dose HBIG group. Using the propensity score 1:1 matching method, 38 and 18 pairs were defined as adhering to and not adhering to the Milan criteria. For each pair, HCC recurrence, HBV recurrence and overall survival were analyzed by the Kaplan-Meier method and the log rank test according to the HBIG dose. RESULTS: Among those who met the Milan criteria, the 6-mo, 1-year, and 3-year HCC recurrence-free survival rates were 88.9%, 83.2%, and 83.2% in the low-dose HBIG group and 97.2%, 97.2%, and 97.2% in the high-dose HBIG group, respectively(P = 0.042).In contrast, among those who did not meet the Milan criteria, HCC recurrence did not differ according to the HBIG dose(P = 0.937). Moreover, HBV recurrence and overall survival did not differ according to the HBIG dose among those who met(P = 0.317 and 0.190, respectively) and did not meet(P = 0.350 and 0.987, respectively) the Milan criteria. CONCLUSION: High-dose HBIG therapy can reduce HCC recurrence in HBV-DNA/HBe Ag-positive patients after LDLT.

Intramuscular hepatitis B immune globulin combined with lamivudine in prevention of hepatitis B recurrence after liver transplantation

BACKGROUND: Combined hepatitis B immune globulin (HBIg) and lamivudine in prophylaxis of the recurrence of hepatitis B after liver transplantation has significantly improved the survival of HBsAg positive patients. This study was undertaken to evaluate the outcomes of liver transplantation for patients with hepatitis B virus (HBV). METHODS: A retrospective chart analysis and a review of the organ transplant database identified 51 patients (43 men and 8 women) transplanted for benign HBV-related cirrhotic diseases between June 2002 and December 2004 who had survived more than 3 months. HBIg was administered intravenously during the first week and intramuscularly thereafter. RESULTS: At a median follow-up of 14.1 months, the overall recurrence rate in the 51 patients was 3.9% (2/51). The overall patient survival was 88.3%, and 82.4% after 1 and 2 years, respectively. A daily oral dose of 100 mg lamivudine for 2 weeks before transplantation for 10 patients enabled 57.1% (4/7) and 62.5% (5/8) of HBV-DNA and HBeAg positive patients respectively to convert to be negative. Intramuscular HBIg was well tolerated in all patients. CONCLUSION: Lamivudine combined with intramuscular HBIg can effectively prevent allograft from the recurrence of HBV after liver transplantation.

Prevention of vertical transmission of hepatitis B virus infection

Hepatitis B virus(HBV)is the leading cause of chronic viral hepatitis.Annually,almost two million children younger than 5 years acquire the infection,mostly through vertical or horizontal transmission in early life.Vertical transmission of HBV is a high efficacy phenomenon ranging,in the absence of any preventive interventions,from 70%to 90%for hepatitis e antigen positive mothers and from 10%to 40%for hepatitis e antigen-negative mothers.Maternal viraemia is a preeminent risk factor for vertical transmission of HBV.Maternal screening is the first step to prevent vertical transmission of HBV.Hepatitis B passive and active immunoprophylaxis at birth together with antiviral treatment of highly viraemic mothers are the key strategies for global elimination of HBV infection.Strategies are needed to promote implementation of birth-dose vaccination and hepatitis B immunoglobulins in low-and middle-income countries where the prevalence of the infection is at the highest.

Prevention of recurrent hepatitis B infection after liver transplantation

BACKGROUND:Recurrence of hepatitis B virus(HBV) infection after liver transplantation can lead to graft loss and a reduction in long-term survival.The purpose of this review is to summarize the current therapeutic options for preventing HBV recurrence in liver transplant recipients.DATA SOURCES:Up to January 2013,studies that were published in MEDLINE and EMBASE on prevention of HBV recurrence after liver transplantation were reviewed.RESULTS:There have been remarkable advancements in the past two decades on the prevention of HBV recurrence after liver transplantation,from the discovery of hepatitis B immune globulin(HBIG) and lamivudine monotherapy to the combination therapy using HBIG and lamivudine.With the development of newer and stronger antiviral agents,the need for life-long HBIG is doubtful.With their low resistance profile,oral antiviral prophylaxis using these new agents alone is sufficient and is associated with excellent outcome.CONCLUSIONS:Restoration of host HBV immunity with adoptive immunity transfer and vaccination may represent the ultimate strategy to withdraw prophylactic treatment and to achieve a drug free regimen against HBV recurrence after liver transplantation.

Interactions among age, adiposity, bodyweight, lifestyle factors and sex steroid hormones in healthy Singaporean Chinese men

Aim： To examine the inter-relationships among age, lifestyle factors, anthropometric parameters, percent body fat and steroid hormone parameters in 531 healthy Singaporean Chinese men aged between 29 and 72 years old. Methods： Various lifestyle parameters were quantified through a survey, and testosterone （T）, estradiol （E2）, dehydroepiandrosterone sulphate （DHEAS） and sex hormone binding globulin （SHBG） were measured using established methods. Anthropometric parameters were collected and computed, and percent body fat （Siri） was measured using the DEXA scanner. Results： SHBG, DHEAS, bioavailable-T （Bio-T）, E2, Siri, Ht, W/H, W/Ht and work stress were independently correlated with age. Using multivariate analyses and adjusting for age and other related factors, exercise, smoking and alcohol consumption have positive impacts on androgen levels and body composition. However, black and green tea consumption was associated with negative effects on body composition and with higher levels of E2 and Free Estradiol Index （FEI）. Men with shorter sleep duration had significantly lower T levels as compared to those with 6 h or more of nightly sleep. Higher T levels were associated with lower levels of adiposity and other indices of adiposity, whereas higher E2 levels were related to higher levels of adiposity. Men with higher DHEAS were significantly taller and heavier than those with low DHEAS levels. Conclusion： The study showed the close interactions among the gonadal/adrenal and metabolic compartments, with age being a key determinant in their interactions. Lifestyle factors such as exercise, smoking, sleeping and alcohol and tea consumption might play significantly roles in determining the status of health in men.

Prevention and treatment of hepatitis B recurrence after liver transplantation

OBJECTIVE: To study the efficacy of liver transplantation on end-stage hepatitis B related liver diseases, and the prevention and treatment strategies of hepatitis B recurrence after the transplantation. METHODS: The efficacy of combined treatment of lamivudine and hepatitis B immune globulin (HBIG) therapy on 24 patients who had received liver transplantation was retrospectively studied. RESULTS: All the 24 patients with end-stage hepatitis B-related liver diseases treated with lamivudine alone or combined therapy of lamivudine and HBIG showed normal liver function and 21 of them lost hepatitis B virus (HBV) markers. However, the remaining 3 patients became HBsAg positive again soon after liver transplantation. CONCLUSIONS: Liver transplantation is effective for patients with end-stage hepatitis B-related liver diseases. Combined treatment of lamivudine and HBIG may prevent the recurrence of hepatitis B after the operation.

Novel frameshift mutation causes early termination of the thyroxine-binding globulin protein and complete thyroxine-binding globulin deficiency in a Chinese family: A case report

BACKGROUND Thyroxine-binding globulin(TBG;the gene product of SERPINA7)is the main transporter of thyroid hormones in humans.Mutations in the TBG gene may lead to inherited TBG deficiency.There have been 28 reported mutations that associate with complete TBG deficiency(TBG-CD).Here we identified a novel frameshift mutation causing early termination of the TBG protein and TBG-CD in a Chinese family.CASE SUMMARY A 46-year-old Chinese man was referred to our hospital with normal free thyroxine,free triiodothyronine,thyrotropin,but lower total thyroxine and total triiodothyronine,and undetectable serum TBG,indicative of TBG-CD.Blood samples were obtained from the patient’s family members and thyroid function and serum TBG were evaluated.Genomic DNA from peripheral blood was sequenced to detect possible TBG mutation(s).Quantitative PCR high-resolution melting curve analysis was used to screen TBG-Poly(L283F)among 117 Chinese men.A novel mutation of TBG(p.Phe135Alafs*21),a 19-nucleotide insertion in exon 1,was identified,which resulted in a truncated TBG protein product and caused TBG-CD.The other mutation,identified in the proband’s father,is a known polymorphism,TBG-Poly(L283F).The frequency of the TBG-Poly allele among 117 unrelated Han Chinese men from northeast China was 21.37%.CONCLUSION A novel mutation in the TBG gene associated with the TBG-CD phenotype was identified in a Chinese family.Additionally,it was found that 21.37%of Chinese males had TBG-Poly(L283F).

Effects of high voltage discharge on the human bodies of workers

In this paper,as it is reported,through mechanism analysis,calculation,testing,measuring in the site and the observation ofbiologic effect on workers as well as the peripheral blood test in vitro,there are low energy X-ray and so forth produced due to high volt-age discharge which are harmful physical and chemical factors.Theexistence of these harmful factors affect workers’ health to a certaindegree.The observed biologic indexes are those of peripheral bloodcell effect,lymphocyte,micronuclear,chromosomal aberration,sisterchromatid exchange,blood serum immune globulin,electroen-cephalogram and brain blood current gram. The vitro peripheralblood test indexes are including those of chromosmal aberration,sister chromatid exchange and blood serum immune globulin.Theresults obtained from the said observation and testing express thatthe above mentioned indexes have obvious significance after thecomparison of those between test group and control group treated bystatistics (i.e.P【0.05).Further,the test results also point out that theenvironment of high voltage discharge will creat injury to the workers,therefore a detail research should be taken.

Hemophagocytic lymphohistiocytosis: Recent progress in the pathogenesis, diagnosis and treatment

Hemophagocytic lymphohistiocytosis(HLH) is a hyperinflammatory syndrome that develops as a primary(familial/hereditary) or secondary(non-familial/hereditary) disease characterized in the majority of the cases by hereditary or acquired impaired cytotoxic T-cell(CTL) and natural killer responses. The molecular mechanisms underlying impaired immune homeostasis have been clarified, particularly for primary diseases. Familial HLH(familial hemophagocytic lymphohistiocytosis type 2-5, Chediak-Higashi syndrome, Griscelli syndrome type 2, Hermansky-Pudlak syndrome type 2) develops due to a defect in lytic granule exocytosis, impairment of(signaling lymphocytic activation molecule)-associated protein, which plays a key role in CTL activity [e.g., X-linked lymphoproliferative syndrome(XLP) 1], or impairment of X-linked inhibitor of apoptosis, a potent regulator of lymphocyte homeostasis(e.g., XLP2). The development of primary HLH is often triggered by infections, but not in all. Secondary HLH develops in association with infection, autoimmune diseases/rheumatological conditions and malignancy. The molecular mechanisms involved in secondary HLH cases remain unknown and the pathophysiology is not the same as primary HLH. For either primary or secondary HLH cases, immunosuppressive therapy should be given to control the hypercytokinemia with steroids, cyclosporine A, or intravenous immune globulin, and if primary HLH is diagnosed, immunochemotherapy with a regimen containing etoposide or anti-thymocyte globulin should be started. Thereafter, allogeneic hematopoietic stem-cell transplantation is recommended for primary HLH or secondary refractory disease(especially EBVHLH).

Effects of ultra-high-pressure treatment on the structural and functional properties of buckwheat 13S globulin

Components with strong adsorption capacity for cholates from buckwheat proteins were screened, separated and purified by several methods, and the effects of ultra-high-pressure(UHP) on the structure and function of buckwheat 13S globulin(BW13SG) were studied. Samples were treated by UHP at different p H(3.0 and 7.0) value(s) and at 100–500 MPa for 10–30 min. The results showed that the tertiary structure of BW13SG was partially denatured and aggregated. The decrease in the unordered structure indicated that UHP resulted in a looser secondary structure of BW13SG. UHP treatment also increased solubility, emulsion activity and stability, foaming capacity and stability. The samples treated at 500 MPa, p H 3.0 for 30 min had the most enhanced functionality. Moreover, under this condition, the sodium cholate and sodium deoxycholate adsorption capacities of BW13SG were both higher than 98% and the adsorption capacity of sodium taurocholate, which can be difficult to adsorb, was higher than 60%.
