An SPS-RS Technique for the Fabrication of SrMoO Powellite Mineral-like Ceramics for Sr Immobilization.

This paper reports a method for the fabrication of mineral-like SrMoO ceramics with a powellite structure, which is promising for the immobilization of the high-energy Sr radioisotope. The reported method is based on the solid-phase "in situ" interaction between SrO and MoO oxides initiated under spark plasma sintering (SPS) conditions. Dilatometry, XRD, SEM, and EDX methods were used to investigate the consolidation dynamics, phase formation, and structural changes in the reactive powder blend and sintered ceramics.

Uterine adenosarcoma is an uncommon biphasic tumor with benign epithelial and malignant mesenchymal components, often presenting difficulties for morphological diagnosis. We describe 5 cases of adenosarcoma of the uterine corpus and cervix, and vaginal stump in patients aged 46-76 years. Clinical data, ultrasound results, morphological data, including immunohistochemical studies with antibodies to CD10, estrogen and progesterone receptors, desmin, smooth muscle actin, and Ki-67 are presented.

[Metastatic leiomyoma or synchronous lesion of the uteri corpus and vulva?].

Objective: To reveal the morphological characteristics of simultaneously diagnosed leiomyoma of the corpus uteri and vulva.

Subject And Methods: The paper describes a case of multiple uterine leiomyomas concurrent with vulvar leiomyoma in a 39-year-old patient with progressive tumor nodule growth over 2 years. Vulvar tumor was biopsied simultaneously with extirpation of the uterus; vulvar leiomyoma was removed six months later.

[Features of the pathogenesis of the placenta growing in the scar after cesarean section].

Objective: to investigate the structural and pathogenetic features of pathological placental attachment in the scar after cesarean section.

Material And Methods: The investigators explored 12 uteri; 11 of which were removed with placentas at 9 to 38 weeks' gestation (one in the first trimester, three at 18-22 weeks, two at 32-35 weeks, and five at 37-38 weeks); one uterus was removed after an artificial abortion at 12 weeks' gestation in the scar, as well as the scars excised in the first trimester in non-developing (n=4) and progressive (n=2) pregnancies. For histological examination, fragments of the full-thickness uterine wall were taken from the placental bed in different areas.

[Twin pregnancy with complete hydatidiform mole].

The paper describes a case of twin pregnancy with complete hydatidiform mole (CHM). According to the data available in the literature, the concurrence of CHM with a normal placenta and a viable fetus occurs in 1 per 20,000-100,000 pregnancies, requires a differential diagnosis with partial hydatidiform mole and placental mesenchymal dysplasia, and is characterized by a high rate of complications. In this concurrence, the frequency of persistent trophoblastic disease is as high as 50%.

[Placental alterations in pregnant women with autoimmune polyglandular endocrinopathy].

The paper gives the results of a morphological study of 13 placentas from patients with rare autoimmune polyglandular syndrome and adrenal insufficiency, a disease history of 2 to 14 years, receiving corticosteroid replacement therapy. All pregnancies were full-term; labors were term surgical. The clinical and morphological associations suggest the placental alterations characteristic of diabetes mellitus, autoimmune diseases, uteroplacental and placentofetal ischemia.

[Massive subchorial thrombosis].

Massive subchorial thrombosis (MSCT) is a placental abnormality, the etiology and pathogenesis of which remain inadequately studied. MSCT is characterized by a clinical symptom complex comprising marked intrauterine growth retardation, oligohydramnios, and fetal distress due to placental circulatory problems. Perinatal outcomes are appreciably determined by the term of pregnancy, the degree of placental insufficiency, and neonatal status.

[Endometrial hyperplastic changes and precancerous conditions: terminology and classification].

The paper presents the data available in the literature on the debated aspects of the terminology and classification of endometrial hyperplastic lesions, precancerous conditions of the corpus uteri. Particular emphasis is laid on the low reproducibility of the histological diagnosis of endometrial changes in accordance with the WHO criteria. Focus is on the disadvantages of a morphometric study for diagnosing endometrial intraepithelial neoplasia.

[The problem of study of unexplainable antenatal fetal death].

The paperpresents the data on the causes ofperinatal mortality. Particular emphasis is placed on unexplainable antenatal fetal death, the absence of uniform terminology or a consensus classification of the causes of antenatal fetal death, and the principles in placental studies and stillborn baby autopsy. Various aspects of sophisticated relations in the mother-placenta-fetus system are considered.

[Quantitative evaluation of the activity of nuclear Ca2+/Mg2+-dependent endonucleases in hyperplasia and cancer of the endometrium].

Endometrial carcinoma is the most incident cancer of human reproductive system. There are unequivocal evidences of relationship between complex and atypical hyperplasia and development of cancer. Apoptosis plays a significant role in the maintenance of equilibrium between cell death and proliferation and contributes to prevention of tumorigenesis.

[The clinical importance of the dopplerometric study of the blood flow in the normal iliac, uterine and ovarian arteries, in myoma and in endometriosis interna of the corpus uteri].

Dopplerometric investigation of pelvic arteries was carried out in 30 women without gynecologic diseases, in 51 patients with internal endometriosis, and 48 ones with uterine myomas. Internal endometriosis of the uterus was found to be characterized by specific qualitative changes in spectral curves of bloodstream velocity in the internal iliac and uterine arteries. Moreover, progressive changes in spectral curves related to dissemination of endometrioid heterotopias were revealed.

Modern Approach to Myomectomy on the Basis of Ultrastructural Analysis and Ribonucleotide Reductase Determination in Neoplasma and Myometrium.

Myomectomy was performed in 950 patients under age 35; laparoscopy and laser was applied in 94 and 134 patients respectively. To evaluate the necessity of subsequent therapy, we studied the myoma nodule ultrastructure by means of pathology, electron microscopy and histochemistry. For the first time we measured enzyme ribonucleotide reductase (RR) in the nodule and surrounding tissues using electron magnetic resonance imaging.

[Endometrial and ovarian morphology in internal uterine endometriosis].

The ovaries and endometrium were examined in 66 patients with internal uterine endometriosis with various degrees of the process dissemination. A high incidence of combinations of uterine endometriosis with hyperplastic processes in the ovaries was revealed (72.7%) and a relatively low incidence of uterine body mucosa involvement (31.

[Experimental validation of the efficacy of laser-magnetic therapy for chronic placental insufficiency].

A new pathogenetically based non-medicamentous method for correction of uteroplacental bloodflow disturbances has been developed on the model of chronic placental insufficiency in rats. A single 5 min laser-magnetic exposure on day 21 of normal pregnancy resulted in a vasodilating effect with reduction of the peripheral resistance in the uterine horn vessels and with improvement of their blood supply. A new LAMA laser magneto-therapeutic device was employed.

[Morphofunctional characteristics of the placenta of women living in extreme conditions of the Aral cost line].

Morphologic examination of the placenta from 41 puerperants living near the Aral sea revealed an increase of its mass and changes in other parameters. The detected pathologic processes: hemodynamic disorders and dystrophic changes--are not specific and contribute to the development of placental insufficiency. The majority (85.

[Current concepts in observation and treatment of patients with internal endometriosis of the uterus].

The paper outlines the issues of improving and systematizing clinical instrumental diagnostic and therapeutical techniques for internal endometriosis. The results of examining 220 patients with internal endometriosis, out of whom 116 were further operated on, have been prospectively and retrospectively studies. Based on the histological findings of the gross specimens intraoperatively removed, the authors analyzed the predictive value of clinical and instrumental diagnostic criteria, including those of transvaginal echography, Doppler echometry of the arteries supplying the uterus, those of hysteroscopy and the computer hysterosalping graphic technique developed by them.

[The ultrastructure and electron-histochemical characteristics of the stromal cells of the endometrium].

Histologic, histochemical, electron-microscopic and ultracytochemical studies of cellular populations of the endometrial stroma and the vascular component, carried out in 33 women of a productive age in various phases of the cycle (on days 5-28) showed interactions of the cellular elements (fibroblast-like cells, predecidual cells, endometrial granulocytes, endotheliocytes, cells of a hematogenic origin) within and between the populations over the course of the cycle; all the cells were found functionally heterogenic, this underlying the endometrial homeostasis maintenance. Disturbances in any of the components of these interactions may result in a pathologic process in the uterine body mucosa.

[The clinico-morphological and cytological characteristics of the ecto- and endocervix with the use of the oral contraceptive triregol].

Cervix uteri status was examined in 55 young nulliparous women in the course of triphasic oral contraception. The status of the cervix uteri was assessed on the basis of clinical, colposcopic, cytologic, and morphofunctional examinations. Triphase oral contraception with triregol was found conducive to the formation of squamous-cell metaplasia in ectopic sites, this promoting epithelialization of the cervix uteri.

[Alternative solutions in the treatment of patients with combined benign endometrial and myometrial pathology].

The study included 96 women with combined benign hyperplastic uterine conditions. Half of them underwent a radical uterine resection and were examined at 3.1 +/- 0.

[Effectiveness of hormonal therapy of endometrioid ovarian cysts].

Patients with ovarian endometriosis have been examined during the follicular and luteal phase of the ovulatory and the second phase of the anovulatory cycles. Estradiol and progesterone blood concentrations measured on operation days and during the respective ovulatory phases were in a normal range. Ovulation and endometrial hyperplasia reduced basal progesterone concentrations.
