Pregnancy And Lactation

The effects of pregnancy and lactation on hematochemical and mineral parameters were evaluated in Ettawa cross-bred goats in Disctrict Kulonprogo, Yogyakarta, Indonesia. Blood plasma samples were collected from 14 th pregnant goats (2 month n=4; 3 month n=6; 4 month n=4) and 16 lactation goats (1 month, n= 4; 2 month, n=5; 3 month, n=3 and 4 month, n=4). Blood serum samples were collected from 18 pregnanct goats (1 month, n=3; 2 month, n=2; 3 month, n=6; 4 month, n=4) and 16 lactation goats (1 month, n=4; 2 month, n=5; 3 month, n=3; 4 month, n=4).  The does averaged 2.5-4 years old and their mean body weights were 30-40 kg. The current result showed that pregnant does recorded higher (p<0.05) values of RBCs and hematocrites compared to lactating does. The higher RBCs during the first and third month of pregnantion and the higher hematocrites values during the first of pregnantion. There were not significant differences in MCV, MCH, MCHC, neutrophyls,  limphocytes, monocytes, WBCs, eosinophyls, and minerals Mg2+, in organic  , Na+, K+ and Cl-during pregnantion and lactation.  The results indicated that pregnantion and lactation has significant effect on RBCs and hematocrites of Ettawa crossbred goats in district Disctrict Kulonprogo, Yogyakarta, Indonesia

ABSTRACTBrucella abortus, a smooth strain of the genusBrucella, is the causative agent of bovine brucellosis. To support the ongoing development of diagnostic tests for bovine brucellosis, the use of Protein Saver cards (Whatman) for bovine blood serum and plasma sample collection has been evaluated. These cards offer significant logistical and safety alternatives to transporting and storing liquid samples and may aid in diagnostic programs and validation studies. To evaluate the utility of these cards, 204 bovine blood serum samples fromBrucella-infected and noninfected animals were stored on and eluted from the Protein Saver cards. Anti-Brucellasmooth lipopolysaccharide (sLPS) antibody titers for the serum eluates were compared to those of the unprocessed original serum samples by indirect enzyme-linked immunosorbent assay (ELISA). The results showed a highly significant correlation between titers from the serum eluates and the unprocessed sera. Therefore, under these circumstances, serum eluates and unprocessed serum samples may be used interchangeably. Blood plasma from 113 mitogen-stimulated whole-blood samples was added to and eluted from the Protein Saver cards. The gamma interferon (IFN-γ) titers in the plasma eluates were compared to those of the unprocessed plasma samples obtained by IFN-γ ELISA. The results showed a significant correlation between the plasma eluates and the unprocessed plasma samples. To derive a signal in the plasma eluate, it was necessary to develop a novel and highly sensitive ELISA for the detection of IFN-γ. The serum samples stored on cards at room temperature over a 10-day period showed little variation in antibody titers. However, the plasma eluates showed a progressive loss of IFN-γ recovery over 10 days when stored at room temperature.

The toxic effect of lead (Pb) causes to anemia and iron deficiency in human body. So, the lead determination in blood/serum samples is very important.  In this study, a novel adsorbent based on sulfamethizole functionalized on nanographene oxide (C3H10N4O2S2-NGO; SM-NGO) was used for extraction of Pb(II) from human blood, serum and plasma samples in battery manufactories workers by SF-D-µ-SPE.  By procedure, 25 mg of SM-NGO mixed with 10 mL of human blood/serum or plasma samples and aspirated by 10 mL of syringe tube. After sonication of samples for 5 min, the Pb ions adsorbed based on sulfur of SM-NGO adsorbent at pH=6 and the solid phase separated by syringe coupled to Millex-FG hydrophobic PTFE membrane (0.2 µm). Then, the lead ions were back-extracted from SM-NGO/PTFE by elution phase with 0.5 mL of nitric acid solution (0.5 M). Finally, the concentrations of Pb(II) ions were determined by AT-FAAS.

AbstractUterine fibroids (UF) is the most common (about 70% cases) type of gynecological disease, with the recurrence rate varying from 11 to 40%. Because UF has no distinct symptomatology and is often asymptomatic, the specific and sensitive diagnosis of UF as well as the assessment for the probability of UF recurrence pose considerable challenge. The aim of this study was to characterize alterations in the lipid profile of tissues associated with the first-time diagnosed UF and recurrent uterine fibroids (RUF) and to explore the potential of mass spectrometry (MS) lipidomics analysis of blood plasma samples for the sensitive and specific determination of UF and RUF with low invasiveness of analysis. MS analysis of lipid levels in the myometrium tissues, fibroids tissues and blood plasma samples was carried out on 66 patients, including 35 patients with first-time diagnosed UF and 31 patients with RUF. The control group consisted of 15 patients who underwent surgical treatment for the intrauterine septum. Fibroids and myometrium tissue samples were analyzed using direct MS approach. Blood plasma samples were analyzed using high performance liquid chromatography hyphened with mass spectrometry (HPLC/MS). MS data were processed by discriminant analysis with projection into latent structures (OPLS-DA). Significant differences were found between the first-time UF, RUF and control group in the levels of lipids involved in the metabolism of glycerophospholipids, sphingolipids, lipids with an ether bond, triglycerides and fatty acids. Significant differences between the control group and the groups with UF and RUF were found in the blood plasma levels of cholesterol esters, triacylglycerols, (lyso) phosphatidylcholines and sphingomyelins. Significant differences between the UF and RUF groups were found in the blood plasma levels of cholesterol esters, phosphotidylcholines, sphingomyelins and triacylglycerols. Diagnostic models based on the selected differential lipids using logistic regression showed sensitivity and specificity of 88% and 86% for the diagnosis of first-time UF and 95% and 79% for RUF, accordingly. This study confirms the involvement of lipids in the pathogenesis of uterine fibroids. A diagnostically significant panel of differential lipid species has been identified for the diagnosis of UF and RUF by low-invasive blood plasma analysis. The developed diagnostic models demonstrated high potential for clinical use and further research in this direction.

Fourteen blood samples from patients with melanomas and 11 blood samples from healthy subjects were analyzed by matrix-assisted laser desorption/ionization mass spectrometry. The study focussed on species of low molecular weight, in the 800–5000 Da range, present in plasma and sera. While for healthy subjects plasma samples lead to the production of a higher number of ionic species, for melanoma patients a high number of diagnostic ions, present with high frequency and with quite high relative abundance, are present, in particular, in serum samples and, to a lesser extent, also in plasma. Since plasma samples are obtained more easily in comparison to sera, it is possible to suggest that plasma can also be used for these studies.

The plasma samples of 34 primary donors (22 men and 12 women) for the first time given the plasma by automated plasmapheresis (control surveillance), and 54 active donors of blood plasma (40 men and 14 women) being donors with non-less 14 days interval between donations, have been examined. The active male donors’ plasma averaged at 18,63±1,71 with individual index fluctuations from 2 to 78, female donors’ – 14,09±1,95 with individual index fluctuations from 2 to 45. The method of plasma obtaining is a manual plasmapheresis method. The surveyed groups were homogeneous for age and sex. Hematologic and biochemical parameters of all those persons have been examined and, basing on the conclusion of the professionals, everyone was admitted to the plasma donation. The content of middle mass molecules in plasma were determined by method of N.I. Gabrieljan, V.I. Lipatovoj (1984). The content of biogenic amines free fractions in plasma were determined by fluorometric method of B.V. Mikhailichenko, S.V. Vydyborets (1999). Analysis of the results showed that in the donor plasma samples obtained by manual plasmapheresis level of middle mass molecules, histamine, serotonin is significantly higher. The significance of obtained results has also been discussed.

ABSTRACTAccurate determination of the genetic diversity present in the HIV quasispecies is critical for the development of a preventative vaccine: in particular, little is known about viral genetic diversity for the second type of HIV, HIV-2. A better understanding of HIV-2 biology is relevant to the HIV vaccine field because a substantial proportion of infected people experience long-term viral control, and prior HIV-2 infection has been associated with slower HIV-1 disease progression in coinfected subjects. The majority of traditional and next-generation sequencing methods have relied on target amplification prior to sequencing, introducing biases that may obscure the true signals of diversity in the viral population. Additionally, target enrichment through PCR requiresa priorisequence knowledge, which is lacking for HIV-2. Therefore, a target enrichment free method of library preparation would be valuable for the field. We applied an RNA shotgun sequencing (RNA-Seq) method without PCR amplification to cultured viral stocks and patient plasma samples from HIV-2-infected individuals. Libraries generated from total plasma RNA were analyzed with a two-step pipeline: (i)de novogenome assembly, followed by (ii) read remapping. By this approach, whole-genome sequences were generated with a 28× to 67× mean depth of coverage. Assembled reads showed a low level of GC bias, and comparison of the genome diversities at the intrahost level showed low diversity in the accessory genevpxin all patients. Our study demonstrates that RNA-Seq is a feasible full-genomede novosequencing method for blood plasma samples collected from HIV-2-infected individuals.IMPORTANCEAn accurate picture of viral genetic diversity is critical for the development of a globally effective HIV vaccine. However, sequencing strategies are often complicated by target enrichment prior to sequencing, introducing biases that can distort variant frequencies, which are not easily corrected for in downstream analyses. Additionally, detaileda priorisequence knowledge is needed to inform robust primer design when employing PCR amplification, a factor that is often lacking when working with tropical diseases localized in developing countries. Previous work has demonstrated that direct RNA shotgun sequencing (RNA-Seq) can be used to circumvent these issues for hepatitis C virus (HCV) and norovirus. We applied RNA-Seq to total RNA extracted from HIV-2 blood plasma samples, demonstrating the applicability of this technique to HIV-2 and allowing us to generate a dynamic picture of genetic diversity over the whole genome of HIV-2 in the context of low-bias sequencing.

Radiation therapy (RT) is used to treat approximately 50% of all cancer patients. However, RT causes a wide range of adverse late effects that can affect a patient’s quality of life. There are currently no predictive assays in clinical use to identify patients at risk of normal tissue radiation toxicity. This study aimed to investigate the potential of Fourier transform infrared (FTIR) spectroscopy for monitoring radiotherapeutic response. Blood plasma was acquired from 53 prostate cancer patients at five different time points: prior to treatment, after hormone treatment, at the end of radiotherapy, two months post radiotherapy and eight months post radiotherapy. FTIR spectra were recorded from plasma samples at all time points and the data was analysed using MATLAB software. Discrimination was observed between spectra recorded at baseline versus follow up time points, as well as between spectra from patients showing minimal and severe acute and late toxicity using principal component analysis. A partial least squares discriminant analysis model achieved sensitivity and specificity rates ranging from 80% to 99%. This technology may have potential to monitor radiotherapeutic response in prostate cancer patients using non-invasive blood plasma samples and could lead to individualised patient radiotherapy.

Currently, one of the main economic policies of the Russian Federation in the field of food security is production of safe food and consumer protection. The aim of the research was to study the content of such toxic elements as Zn, Cd and Pb in milk and blood of cows. Experimental studies were carried out at stud farms Plemzavod Tayozhny LLC in Suhobuzimsky District and OPH Solyanskoe LLC in Rybinsk District, Krasnoyarsk Krai, Russian Federation. The milksamples were studied by atomic absorption method; the blood serum samples, by mass spectrometry. Blood serum samples were obtained by sedimentation of whole blood and retraction of the blood clot followed by centrifugation. The obtained data were processed by the method of variation statistics with the calculation of statistical indicators. The lowest contents of Zn, Cd and Pb were found in blood serum of the cows of OPH Solyanskoe LLC; it was 0.038, 0.001, and 0.002 mg/l, respectively. The milk samplescollected at Plemzavod Tayozhny LLCcontained less heavy metals than those collected at OPH Solyanskoe LLC: Zn by 2.069 mg/l, Cd by 0.01 mg/l, and Pb by 0.061 mg/l (P>0.999). When calculating the correlation coefficients, weak positive and negative correlationswere established between Zn and Pb content in blood and milk. The detected amounts of toxic elements did not exceed the maximum permissible concentrations, except for Pb content in milk sampled at OPH Solyanskoe LLC, which was higher than the standard content by 0.026 mg/l.
