A study of biochemical changes in river buffaloes (Bubalus bubalis) naturally infected with Anaplasma marginale

Anaplasma marginale as an intracellular rickettsia, endemic in tropical and subtropical regions of the world. This study was performed to determine A. marginale infection, molecularly, and to investigate its effects on some serum biochemical parameters in river buffaloes referred to Ahvaz abattoir, Southwest Iran. A total of 103 apparently healthy river buffaloes were randomly sampled. Whole blood samples were subjected to PCR analysis and blood smears were examined microscopically for the presence of Anaplasma inclusions. Serum biochemical parameters including total protein, albumin, glucose, urea, iron, total bilirubin, total cholesterol, Calcium, Phosphorus and Magnesium concentrations, aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities and also serum electrolytes comprising Na and K were assessed. The results revealed that 16 and 32 samples were infected with A. marginale in microscopic and PCR assessment, respectively. Serum biochemical analysis showed no significant difference between A. marginale infected and non-infected buffalo groups. It can be concluded that infection with A. marginale does not lead to much pathogenicity in river buffaloes, so that in infected animals, no clinical signs or abnormalities in the performance indicators of various organs can be detected at the laboratory level. However, the role of this species as a reservoir of this microorganism in nature and in the epidemiology and transmission of anaplasmosis to other species remains significant. Buffaloes can be a substitute to raising cattle in regions with high occurrence of anaplasmosis.

Metabonomic study of biochemical changes in serum of PCPA-induced insomnia rats after treatment with Suanzaoren Decoction

Suanzaoren Decoction(SZRD) is a classical formula for the clinical treatment of insomnia. This study analyzed the effect of SZRD on endogenous metabolites in insomnia rats based on metabonomics and thereby explored the anti-insomnia mechanism of SZRD. To be specific, DL-4-chlorophenylalanine(PCPA) was used to induce insomnia in rats. Then pathological changes of the liver and brain were observed and biochemical indexes such as 5-hydroxytryptamine(5-HT), dopamine(DA), glutamate(Glu), γ-aminobutyric acid(GABA), and norepinephrine(NE) in the hippocampus and prostaglandin D2(PGD2), tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), and IL-6 in the serum of rats were detected. On this basis, the effect of SZRD on PCPA-induced insomnia rats was preliminarily assessed. The metabolic profile of rat serum samples was further analyzed by ultra-performance liquid chromatography-quadrupole-time of flight-tandem mass spectrometry(UPLC-Q-TOF-MS/MS). Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were combined with t-test and variable importance in projection(VIP) to identify differential metabolites, and MetaboAnalyst 5.0 was employed for pathway analysis. The results showed that SZRD could improve the pathological changes of brain and liver tissues, increase the levels of neurotransmitters 5-HT, DA, and GABA in hippocampus and the level of PGD2 in hypothalamic-pituitary-adrenal axis(HPA axis), and reduce the levels of IL-1β and TNF-α in serum of insomnia rats. Metabonomics analysis yielded 12 significantly changed potential metabolites: 5-aminovaleric acid, N-acetylvaline, L-proline, L-glutamate, L-valine, DL-norvaline, D(-)-arginine, pyroglutamic acid, 1-methylguanine, L-isoleucine, 7-ethoxy-4-methylcoumarin, and phthalic acid mono-2-ethylhexyl ester(MEHP), which were related with multiple biochemical processes including metabolism of D-glutamine and D-glutamate, metabolism of alanine, aspartate, and glutamate, metabolism of arginine and proline, arginine biosynthesis, glutathione metabolism. These metabolic changes indicated that SZRD can improve the metabolism in insomnia rats by regulating amino acid metabolism.

ENDOTHELIAL DYSFUNCTION AND POLYHYPOVITAMINOSIS IN PATIENTS WITH COMPLICATED DESTRUCTIVE ONYCHOMYCOSIS AND THE COMORBID METABOLIC SYNDROME

In the pathogenesis of chronic infectious fungal processes, an important role is determined by the weakening of the body's protective factors. There are endogenous and exogenous that contribute to the transformation of fungi from vegetation to pathogenic. Endogenous factors (age, general infections, metabolic diseases, hypo- and avitaminosis, metabolic syndrome, gastrointestinal diseases, neuropathy) are define some clinical variants. Destructive fungal lesions predominate in middle-aged and elderly people, in elderly patients nail pathology is half of all observations of purulent-necrotic chronic lesions of the distal parts of the hand and foot. The purpose of the work was to introduce minimally invasive nail removal or resection of nails by block-shaped eponychectomy access with the use of pedicure instruments, study of biochemical changes in the background of pathology, detection of correlations between hypo- and avitaminosis with the development of destructive onychomycosis. It has been established that conservative, podiatric and orthopedic treatment of mycotic surgical lesions and secondary nail incarnation are not very effective, while some classical methods are Dupuytren's nail removal, Emmert-Schmiden operation and others in 2-20% of cases (depending on the absence or presence of onychocryptosis and associated fungal lesions) determine recurrences. Instead, the proposed low-trauma removal or resection of nails by block-shaped eponychectomy access using pedicure instruments, excision of dermatophytoma with partial marginal matrixectomy, which significantly reduces the number of recurrences of ingrowth (respectively 1-3% in the early stages and , 3,25% та 6,42% periods of growth, χ2 = 28,17, p<0,01) and determines the improvement of quality of life. The study of endothelial function revealed the presence of endothelial dysfunction in most patients, which confirms our previous studies and literature data. Blood lipid spectrum was significantly higher in both groups of patients (main and comparison group), compared with almost healthy individuals (p<0.01 for both groups, compared with controls), which is consistent with the literature. It was found that the supply of vitamins B1, B2, PP, B6 and C directly correlated with the severity of the underlying disease. In patients with polyonychomycosis with significant symptoms of background polyhypovitaminosis , some purulent complications of mycotic onychodestruction were detected – subungual abscess / panaritium, complicated nail incarnation and mycotic-associated paronychia with purulent onychia / onycholysis of more than three nail plates. For comparison, in the other half of the sample of persons with less pronounced symptoms of polyhypovitaminosis, some purulent complications were found in only 37.5% of the subsample, which suggests that there is a relationship between the manifestations of multivitamin deficiency and the severity of necrotic complications. Low-traumatic mobilization of the nail through a block-like eponihectomy and nail plates removal or resection (some nail incarnation ) of through areas of onycholysis/onychomadesis, or resection of nails through hyperkeratosis / onycholized structures using our methods, according to our comp lex analysis, due to reduction of intraoperative injury, determines increasing the rate of wound healing ( χ 2=32,14, p<0,01) and statistically significant minimization of the risk of mixed and reinfection of adjacent anatomical structures.

To the remark of F. K. Kessel "Chloroform anesthesia or toxicosis from a biochemical point of view"

In our work on the study of biochemical changes in blood during chloroform and ether anesthesia, it is indicated that the lipolytic enzyme gives a significant increase in the days following chloroform anesthesia. As you can see from the table. Lipase No. 3 gives in some cases the maximum increase in a day after anesthesia, in most cases the lipenzyme continues to increase in 48 hours (the same picture was given by the rabbits No. 23, B and C mentioned in the text).

Toward Raman Subcellular Imaging of Endothelial Dysfunction.

Multiple diseases are at some point associated with altered endothelial function, and endothelial dysfunction (ED) contributes to their pathophysiology. Biochemical changes of the dysfunctional endothelium are linked to various cellular organelles, including the mitochondria, endoplasmic reticulum, and nucleus, so organelle-specific insight is needed for better understanding of endothelial pathobiology. Raman imaging, which combines chemical specificity with microscopic resolution, has proved to be useful in detecting biochemical changes in ED at the cellular level. However, the detection of spectroscopic markers associated with specific cell organelles, while desirable, cannot easily be achieved by Raman imaging without labeling. This critical review summarizes the current advances in Raman-based analysis of ED, with a focus on a new approach involving molecular Raman reporters that could facilitate the study of biochemical changes in cellular organelles. Finally, imaging techniques based on both conventional spontaneous Raman scattering and the emerging technique of stimulated Raman scattering are discussed.

Infrared Spectroscopy Based Study of Biochemical Changes in Saliva during Maximal Progressive Test in Athletes.

This study aims to explore biochemical changes in saliva during cardiorespiratory exercise using attenuated-total-reflectance-Fourier-transform-infrared-spectroscopy (ATR-FTIR). Saliva and blood samples were obtained from six athletes at rest, and after running at speeds of 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 kilometers-per-hour (km/h) on a treadmill (maximal stress test). Saliva ATR-FTIR spectra were analyzed using deconvolution and multivariate analysis. Area-under-the-curve calculations suggest differential changes in glucose, lactate, protein, lipids, carbohydrate and phosphate content in saliva during the test. Increases in glucose and lactate levels with increasing speeds were verified by simultaneous measurement of blood glucose and lactate levels using standard equipment (Roche®). Multivariate principal-component-analysis (PCA) showed discrete clusters for low (rest-14 km/h) and high (15 - 20 km/h) speeds, and PCA-linear-discriminant-analysis showed 100% classification of 18 - 20 km/h as high speed. Overall, results suggest the possibility of using this non-invasive saliva-based ATR-FTIR method for biochemical assessment during sports exercise and stress tests.

SR-FTIR spectro-microscopic interaction study of biochemical changes in HeLa cells induced by Levan-C60, Pullulan-C60, and their cholesterol-derivatives

Objects of the present study are improved fullerene C60 drug carrier properties trough encapsulation by microbial polysaccharides, levan (LEV), pullulan (PUL), and their hydrophobized cholesterol-derivatives (CHL and CHP), that show better interaction with cancer cells. The zeta potential, polydispersity index, and the diameter of particles were determined, and their cytotoxicity against three cancer cell lines were tested. Biochemical changes in HeLa cells are analyzed by synchrotron radiation (SR) FTIR spectro-microscopy combined with the principal component analysis (PCA). The most significant changes occur in HeLa cells treated with LEV-C60 and correspond to the changes in the protein region, i.e. Amide I band, and the changes in the structure of lipid bodies and membrane fluidity are evident. The highest cytotoxicity was also induced by LEV-C60. In HeLa cells, cytotoxicity could not be strictly associated with biochemical changes in lipids, proteins and nucleic acids, but these findings are significant contribution to the study of the mechanism of interaction of C60-based nanoparticles with cellular biomolecules. In conclusion, LEV, PUL, CHL, and CHP enhanced fullerene C60 potential to be used as target drug delivery system with the ability to induce specific intracellular changes in HeLa cancer cells.

Вплив 2-(3-аліл-4-оксо-3,4-дигідро-хіназолін- 2-іл-сульфоніл)-N-(2,6-дихлорфеніл)-цераміду на складові хроматину та стан антиоксидантної системи в саркомі 45 і незмінених тканинах шкіри щурів

Стрімке поширення онкологічних захворювань у ХХІ столітті в усьому світі зумовлює інтенсифікацію хіміотерапевтичного лікування даної патології зі застосуванням усе нових і нових цитотоксичних і цитостатичних агентів. Однак це зумовлює зростання й числа побічних ефектів і небажаних наслідків використання даних препаратів. Неспецифічна дія щодо всього організму пацієнта та висока токсичність даної групи лікарських засобів, зокрема, їхня кардіо-, нефро- та нейротоксичність, а також відсутність достатньої інформації щодо віддалених наслідків введення протипухлинних засобів на стан прилеглих тканин, які не були захоплені інвазією пухлини, зумовлюють нагальну потребу в системному вивченні біохімічних змін не лише в пухлині, але й поза її межами. У попередніх експериментах нами було проведене вивчення впливу протипухлинного похідного хіназоліну на складові хроматину, процеси фрагментації ДНК, вміст небілкових і пов’язаних з білками SH-груп у карциномі Герена та незмінених тканинах матки й виявлено специфічність його впливу на низку показників виключно в тканині пухлини. У зв’язку з цим актуальним є з’ясування, чи є виявлена специфічність похідного хіназоліну характерною лише для тканини матки, чи вона поширюється й на інші тканини організму. Мета дослідження – вивчити вплив 2-(3-аліл-4-оксо-3,4-дигідро-хіназолін-2-іл-сульфоніл)-N(2,6-дихлорфеніл)-цераміду (АХДЦ) на ДНК, РНК, білки хроматину, процеси фрагментації ДНК, вміст небілкових і пов’язаних з білками SH-груп у саркомі 45 і незмінених тканинах шкіри щурів. Тварини були розподілені на 3 групи по 6 тварин у кожній: 1 – інтактні щури; 2 – негативний контроль (саркома 45); 3 – саркома 45 + АХДЦ (29,93 мг/кг). Вивчення впливу АХДЦ на ДНК, РНК, білки хроматину, процеси фрагментації ДНК, вміст небілкових і пов’язаних з білками SH-груп у саркомі 45 і незмінених тканинах шкіри показало, що дана сполука вірогідно змінювала більшість досліджуваних показників як порівняно з інтактними тваринами, так і з саркомою 45 без лікування. Специфічність впливу АХДЦ на клітини пухлин була найвираженішою щодо ДНК-фрагментації та змін вмісту РНК, співвідношень РНК/ДНК і РНК/НК. Щодо впливу на вміст SH-груп у тканині саркоми 45 і неуражених пухлиною тканинах шкіри, то в даному випадку ефект АХДЦ був протилежним за напрямком стосовно змін вмісту небілкових і пов’язаних з білками SH-груп.

Evaluating endogenous protease of salting exudates during the salting process of Jinhua ham

Strategies are being pursued with the aim of reducing salt content of dry-cured ham. To evaluate the effect of salting on protease activities, sixteen hams were randomly assigned into two groups (LS group and HS group), and two different levels of NaCl were used to dry-cure green ham. The LS group of 8 hams were salted with 6% salt (w/w), whereas the HS group of 8 hams were salted with 8% salt. The exudates were collected separately at 1, 2 and 7 d of the salting stage. The activities and contents of protease in the exudates were investigated. The intense activities of calpains, cathepsin B and L were observed at 1, 2 and 7 d of salting stage in both LS and HS group. The increased contents of 80 and 76 kDa fragments implied that there was a dramatic release of calpain from ham tissues; lower release rates of cathepsin B and cathepsin L led to high residues in LS group, which may be responsible for the intense degradation of proteins and flavor development of dry-cured ham. This paper provides new insights into the study of biochemical changes of Jinhua ham induced by endogenous protease during the salting stage.

Study of Biochemical Changes after Plateletpheresis in Healthy Male Donors.

There is relatively little information about endogenous biochemical changes in a response to plateletpheresis in healthy donors. We aimed to investigate the changes in different biochemical parameters including glycemic status, insulin resistance, iron status, lipid profile, and inflammatory markers after plateletpheresis in healthy male donors with normal glycemic status. In this study we enrolled 10 male subjects. The glycemic status in all subjects was assessed using an oral glucose tolerance test pre- and post-plateletpheresis at different time intervals (1, 8, and 22 days). Different biochemical parameters including glucose, HbA1c, insulin, lipids, uric acid, transferrin, ferritin, C-reactive protein, and insulin resistance were measured. Repeated ANOVA was utilized for the purpose of statistical comparison of means between different days. Fasting glucose, transferrin, cholesterol, triglycerides, HDL-C, and LDL-C were significantly altered (-3.9%, p < 0.05; -2.7%, p < 0.05; -3.9%, p < 0.05; 23.9%, p < 0.05; -5.5%, p < 0.01, and -9.2%, p < 0.05, respectively) at day 1 following plateletpheresis. There was a gradual reduction in HbA1c and ferritin levels during the time-course of the study, and by day 22, both were significantly lower (-2.0%, p < 0.01; -18.1%, p < 0.05, respectively) when compared to the pre-plateletpheresis levels. Post-plateletpheresis, several biochemical parameters may change significantly in healthy donors. The changes were particularly evident on day 1 and 22 after donation. The potential effects of plateletpheresis need to be considered when interpreting biochemical tests.

Serum metabonomics study of the hepatoprotective effect of Corydalis saxicola Bunting on carbon tetrachloride-induced acute hepatotoxicity in rats by 1H NMR analysis

Corydalis saxicola Bunting (CS), a traditional Chinese folk medicine, has been effectively used for treating liver disease in Zhuang nationality in South China. However, the exact hepatoprotective mechanism of CS was still looking forward to further elucidation by far. In present work, metabonomic study of biochemical changes in the serum of carbon tetrachloride (CCl4)-induced acute liver injury rats after CS treatment were performed using proton nuclear magnetic resonance (1H-NMR) analysis. Metabolic profiling by means of principal components analysis (PCA) and partial least squares-discriminate analysis (PLS-DA) indicated that the metabolic perturbation caused by CCl4 was reduced by CS treatment. A total of 9 metabolites including isoleucine (1), lactate (2), alanine (3), glutamine (4), acetone (5), succinate (6), phosphocholine (7), d-glucose (8) and glycerol (9) were considered as potential biomarkers involved in the development of CCl4-induced acute liver injury. According to pathway analysis by metabolites identified and correlation network construction by Pearson’s correlation coefficency matrix, alanine, aspartate and glutamate metabolism and glycerolipid metabolism were recognized as the most influenced metabolic pathways associated with CCl4 injury. As a result, notably, deviations of metabolites 1, 3, 4, 7 and 9 in the process of CCl4-induced acute liver injury were improved by CS treatment, which suggested that CS mediated synergistically abnormalities of the metabolic pathways, composed of alanine, aspartate and glutamate metabolism and glycerolipid metabolism. In this study, it was the first report to investigate the hepatoprotective effect of the CS based on metabonomics strategy, which may be a potentially powerful tool to interpret the action mechanism of traditional Chinese folk medicines.
