Uterine Flushing

In theory, none of these instruments is anything new or original: the Donalde instrument, manufactured by Arnold and Son in Manchester, resembles the Fritsch-Bosemann catheter, whose beak is elongated in the form of a sharp spoon; its diameter is equal to No. 14 of Duncan's expander (approximately No. 8-9 Hegar).

The role of interferon in early pregnancy in red deer was investigated by (a) measuring production of interferon by the conceptus, (b) testing the anti-luteolytic effect of recombinant interferon-tau in non-pregnant hinds, and (c) treatment of hinds with interferon after asynchronous embryo transfer. Blastocysts were collected from 34 hinds by uterine flushing 14 (n = 2), 16 (n = 2), 18 (n = 8), 20 (n = 13) or 22 (n = 9) days after synchronization of oestrus with progesterone withdrawal. Interferon anti-viral activity was detectable in uterine flushings from day 16 to day 22, and increased with duration of gestation (P < 0.01) and developmental stage (P < 0.01). When interferon-tau was administered daily between day 14 and day 20 to non-pregnant hinds to mimic natural blastocyst production, luteolysis was delayed by a dose of 0.2 mg day(-1) (27.3 +/- 1.3 days after synchronization, n = 4 versus 21 +/- 0 days in control hinds, n = 3; P < 0.05). Interferon-tau was administered to hinds after asynchronous embryo transfer to determine whether it protects the conceptus against early pregnancy loss. Embryos (n = 24) collected on day 6 from naturally mated, superovulated donors (n = 15) were transferred into synchronized recipients on day 10 or day 11. Interferon-tau treatment (0.2 mg daily from day 14 to 20) increased calving rate from 0 to 64% in all recipients (0/11 versus 7/11, P < 0.005), and from 0 to 67% in day 10 recipients (0/8 versus 6/9, P < 0.01). The increased success rate of asynchronous embryo transfer after interferon-tau treatment in cervids may be of benefit where mismatched embryo-maternal signalling leads to failure in the establishment of pregnancy.

Genomic evidence reveals that gene expression in humans is precisely controlled in cellular, tissue-type, temporal, and condition-specific manners. Completely understanding the regulatory mechanisms of gene expression is therefore one of the most important issues in genomic medicine. Surprisingly, recent analyses of the human and animal genomes have demonstrated that the majority of RNA transcripts are relatively small, noncoding RNAs (sncRNAs), rather than large, protein coding message RNAs (mRNAs). Moreover, these sncRNAs may represent a novel important layer of regulation for gene expression. The most important breakthrough in this new area is the discovery of microRNAs (miRNAs). miRNAs comprise a novel class of endogenous, small, noncoding RNAs that negatively regulate gene expression via degradation or translational inhibition of their target mRNAs. As a group, miRNAs may directly regulate ∼30% of the genes in the human genome. In keeping with the nomenclature of RNomics, which is to study sncRNAs on the genomic scale, “microRNomics” is coined here to describe a novel subdiscipline of genomics that studies the identification, expression, biogenesis, structure, regulation of expression, targets, and biological functions of miRNAs on the genomic scale. A growing body of exciting evidence suggests that miRNAs are important regulators of cell differentiation, proliferation/growth, mobility, and apoptosis. These miRNAs therefore play important roles in development and physiology. Consequently, dysregulation of miRNA function may lead to human diseases such as cancer, cardiovascular disease, liver disease, immune dysfunction, and metabolic disorders. microRNomics may be a newly emerging approach for human disease biology.

The aim of the study is to optimize the comprehensive treatment of patients with severe arterial hypertension, through the use of multicomponent rational antihypertensive pharmacotherapy, followed by the use of unloading therapeutic exercises. 32 men with severe arterial hypertension were examined. Initially, a clinical, instrumental and laboratory examination, registration of blood pressure and its 24-hour monitoring were carried out. The average daily systolic (ADBPsyst.) and average daily diastolic (ADBPdiast.) blood pressure were determined. A multicomponent rational antihypertensive pharmacotherapy, according to the clinical recommendations for the treatment of arterial hypertension was selected for all the patients. In at least 3 months after the selection of pharmacotherapy, the patients were divided into two groups, comparable in gender, age, severity of the condition, features of the disease course and medicamentous therapy. Patients of the 1st group (active treatment group) against the background of pharmacotherapy were prescribed unloading therapeutic exercises according to a patented technique. The 2nd group of patients continued to take pharmacotherapy and it was used as a baseline group. The average age in the 1st and 2nd groups was 46,3±6,8 and 43,6±7,2 years, respectively. Patients of the 1st group were prescribed unloading therapeutic exercises and in 3 months in both groups the ADBPsyst. and ADBPdiast. were compared. Initially, there was a significant increase in ADBPsyst. and ADBPdiast. compared to the normal range in both groups. These indicators in both groups differed insignificantly. In 3 months after pharmacotherapy, there was a significant decrease in ADsyst. and ADdiast. in both groups, but these indicators remained elevated and did not reach the target level. Then, in the 1st group, unloading therapeutic exercises were included in the comprehensive treatment. Patients of the 2nd group continued to receive pharmacotherapy. In 3 months after including unloading therapeutic exercises in the 1st group, there was a significant decrease in ADBP (syst. and diast.) not only in comparison with the initial data, but also with the data in 3 months after pharmacotherapy. In the 2nd group, these indicators did not change significantly compared to the three-month data. In 6 months, ADBPsyst. and ADBPdiast. in the 1st group were significantly lower compared to similar indicators in the 2nd group, which proves significant clinical effectiveness of unloading therapeutic exercises in patients of the 1st group. The results obtained confirm that patients with severe arterial hypertension have such types of disorders at the cellular-tissue and microcirculatory level that are not eliminated only by drug therapy. For their high-grade correction, along with multicomponent pharmacotherapy, it is necessary to include unloading therapeutic exercises. To optimize the treatment of severe arterial hypertension against the background of receiving multicomponent antihypertensive pharmacotherapy, it is recommended to include unloading therapeutic exercises in the therapeutic complex.

To examine the hypothesis that increases in fiber cross-sectional area mediated by high-resistance training (HRT) would result in a decrease in fiber capillarization and oxidative potential, regardless of fiber type, we studied six untrained males (maximum oxygen consumption, 45.6 ± 2.3 ml ⋅ kg−1 ⋅ min−1; mean ± SE) participating in a 12-wk program designed to produce a progressive hypertrophy of the quadriceps muscle. The training sessions, which were conducted 3 times/wk, consisted of three sets of three exercises, each performed for 6–8 repetitions maximum (RM). Measurements of fiber-type distribution obtained from tissue extracted from the vastus lateralis at 0, 4, 7, and 12 wk indicated reductions ( P < 0.05) in type IIB fibers (15.1 ± 2.1% vs. 7.2 ± 1.3%) by 4 wk in the absence of changes in the other fiber types (types I, IIA, and IIAB). Training culminated in a 17% increase ( P < 0.05) in cross-sectional area by 12 wk with initial increases observed at 4 wk. The increase was independent of fiber type-specific changes. The number of capillaries in contact with each fiber type increased by 12 wk, whereas capillary contacts-to-fiber area ratios remained unchanged. In a defined cross-sectional field, HRT also increased the capillaries per fiber at 12 wk. Training failed to alter cellular oxidative potential, as measured by succinic dehydrogenase (SDH) activity, regardless of fiber type and training duration. It is concluded that modest hypertrophy induced by HRT does not compromise cellular tissue capillarization and oxidative potential regardless of fiber type.
