Case of unilateral hypoplasia and atresia of the right uterine horn of a gilt

A case of unilateral hypoplasia and atresia of the uterus horn was described in 19 months old gilt. After repeated returns and 9, in total, unsuccessful artificial inseminations, during and after the third oestrus, the gilt was slaughtered and the right horn of the uterus was found to be "blind" at the level of its borders with the uterus body. It contained 150ml of fluid and was about half the length of the left horn (110cm vs. 190cm). Diffused and welloutlined cysts were observed in both horns of the uterus. Histological examination revealed in the endometrium, edema with abundant loose cellular stroma that surrounded numerous hypoplastic glands and hyperaemic blood vessels with thick walls. It is suggested that the production of PGF2a by the hypoplastic and "blind" horn of the uterus interrupted the pregnancy in the left horn.

ANATOMICAL STRUCTURE OF INTERNAL GENITAL ORGANS ZAANEN BREE

Goal. Goat breeding is a promising branch of animal husbandry, which is rapidly developing. The scientific literature has little information about the essential features and differences in the structure of the genital apparatus of goats. With the increase in the number of livestock and selection work in goat breeding, knowledge of the characteristics of the reproductive system is of great importance. Due to lack of knowledge of the structure of the reproductive organs of small cattle, the effectiveness of artificial insemination decreases and inefficient sperm of producers is used, since the complex structure of the cervix of the goat is an obstacle in the artificial introduction of sperm. Therefore, considering the need for further introduction of the method of artificial insemination into practice of goat breeding, the study of the peculiarities of the structure of the internal genital organs of goats is timely and necessary.
 Materials and methods.The study of anatomical features of the structure of the internal genital organs of goats was carried out on animals of the Zaanen breed, imported into the village. Galaiki Tarashchansky district of the Kiev region from Latvia. The material for study was the genitals obtained from goats aged 6-7 years. After the slaughter and bleeding, the genitals were separated into goats. They were then placed in an enameled cuvette and measured with a measuring tape, ruler and caliper. The linear dimensions of the ovaries, the diameter and length of the uterine horns according to the large curvature, the length of the uterine body, the length and diameter of the cervix, the number and structural features of the folds of its mucous membrane, the amount of caruncle, their height and diameter were measured.
 As mentioned earlier, the development of anatomical and physiological basis for artificial insemination of small ruminant animals was carried out mainly on sheep. Therefore, we compared the size of the ovaries, oviducts and uterus in goats of the Zaanen breed of Latvian selection and, according to the literature, the results of studies of similar sheep organs were analyzed.
 As a result of the studies of the morphological parameters of the genitalia of the goats, the following data were obtained: the mass of the left ovary – 0,6 ± 0,06 g, the right – 1,1 ± 0,04 g: the length of the left ovary – 2,0 ± 0,06 Cm, the length of the right – 2,3 ± 0,04 cm. The length of the left oviduct was – 14,2 ± 0,16 cm, and the right – 14,4 ± 0,15 cm. Accordingly, the length of the left horn of the uterus was – 13,7 ± 0,63 cm, the right – 12.2 ± 0,75 cm. The diameter of the left horn of the uterus is – 2.3 ± 0,07 cm, the right horn of the uterus is – 2,8 ± 0,08 cm.
 The morphological parameters of the unpaired genitals of goats were as follows:
 The length of the uterus body was – 1,8 ± 0,15 cm, the cervix was – 5,9 ± 0,29 cm, the cervix diameter was – 1,8 ± 0,08 cm; the number of folds in the cervix is – 4,7 ± 0,50. The height of the caruncle is – 0,5 ± 0,06 cm, their diameter is – 0,7 ± 0,10 cm, the amount of caruncle is – 96,5 ± 1,70, the area of the caruncle is on average – 0,4 ± 0,10 cm2.
 Conclusions. As a result of the carried out researches the anatomical and morphometric characteristics of internal sexual organs of goats are given. These data make it possible to expand and supplement knowledge on the morphology of the reproductive system of farm animals, which must be taken into account in artificial insemination of goats. The data obtained by us are somewhat different from the results of the studies of other authors, but do not contradict them.

Introduction into medical practice of new methods of neuroimaging — computer and magnetic resonance tomography, changed principles of diagnosis of brain morphological changes and opened new horizons in the study of its structure. The aim of our study was to evaluate morphometric parameters of ventricular system of the brain on the results of MRI of elderly persons (females of 56-74 years, males 61-74 years). Object and methods. A survey was conducted in the department of radiation diagnosis of clinical institution «Rivne Regional Clinical Hospital» on computer tomograph General Electric Nealthcare «SignaMRI 1,5T» and in the office of magnetic resonance tomography ща clinical institution «Lutsk Clinical Hospital» on computer tomograph Signa Profile Ce Medical Sistem - 1,5 Tl in standard anatomical planes (sagittal, frontal and axial).bMeasurements were carried out in people without visual signs of organic lesions of the brain and skull. 38 tomograms of elderly patients (14 males and 24 females) were analyzed. 13 morphometric parameters of cerebrospinal fluid system of the brain were studied, namely the size of lateral, the III and IV brain ventricles and the length of aqueductus cerebri in elderly persons of both sexes. In the course of the study we determined the prevalence of size of ventricular system of the brain in males, namely the length of the anterior horns of the lateral ventricles on both sides, the length of the body of lateral ventricles on right and left parts, width of posterior horns of the lateral ventricles and the length of the lower right and left horns, anteroposterior dimensions of the lateral ventricles and the length of the III and IV ventricles. Significant interhemispheric asymmetry with increased body width and length of the rear horn of the lateral ventricle in males, increasing of the length of the lower horn of the lateral ventricle on the right side both in male and female, increasing the anteroposterior size of the left lateral ventricle in men were observed. It can be assumed that this age structural reorganization of the brain are caused by persistent metabolic changes that occur in the brain during the «aging». Conclusions. Thus, there is reason to believe that presented intravital morphometric characteristic of the human brain of elderly persons and identified on this basis criteria of age brain reorganization may be of interest to experts in the field of age anatomy, neurophysiology and neurosurgery, and for specialists of MRI-diagnostic can be an anatomical standard of ventricular system of the brain.

How well can a human mimic the sound of a trumpet?

The length of an uncoiled trumpet horn is more than 2 m, whereas the length of a human supraglottal airway is about 17 cm. The vibrating lips and the vibrating vocal folds can produce similar pitch ranges, but the resonators have vastly different natural frequencies due to the more than 10:1 ratio in airway length. Humans rarely attempt to tune more than one resonance to a harmonic because of the disparity between harmonic spacing and airway resonances spacing, but the brass-like timbre of a human “call” or “belt” can mimic that of a trumpet. A one-dimensional Navier-Stokes solution of non-steady compressible flow in soft-walled airways is used to show the similarities and differences in time-domain wave propagation and resulting flow and pressure frequency spectra along the airways. One striking structural similarity between the human instrument and the brass instrument is the shape of the airway directly above the sound source, known as the mouthpiece for brass and the epilarynx tube for the human airwa...

Morphological parallels of communications between the circumventricular system in adolescents

This article presents, based on the example of morphometric study of magnetic resonance tomograms of persons of various ages, the complex of vital characteristics of the cerebrospinal system of the brain in adolescents. The study tested gender characteristics and inter hemispheric asymmetry of the analyzed indexes. An asymmetry of anatomical structures of the right and left hemispheres with the tendency to increase in their sizes in the right hemisphere was found both for males and for females. Females had some age differences in the longitudinal dimension of the III ventricle (this index was lower in older females), the width and index of the IV ventricle was significantly lower in the 18 and 20 year old girls. Objective and methods. The research was conducted on the base of the radiation diagnosis department of Rivne Regional Clinical Hospital on the CT scan General Electric Healthcare Signa MRI 1.5 T and in the office of magnetic resonance imaging of Lutsk City Clinical Hospital on the CT scan Signa Profile Ce Medical System – 1,5 Tl in standard anatomic planes (sagittal, frontal andaxial). Measurements were carried out in persons without visual signs of organic lesions of the brain and skull. Analysis was made of 11 tomograms (males 17–21 years old – 6 persons, females 16–20 years old – 5 persons). In comparing pairs of parameters (of lateral ventricles) the factor of asymmetry was calculated, which is equal to the difference between the right and left lateral ventricles divided by the sum of right and left ventricles indexes (%). The results were processed by methods of descriptional statistics. In young males of this age group a significant increase in the following indicators was identified: the length of the anterior horn of the lateral ventricle on the right side, the length of the body of the lateral ventricle on both sides and the height of the III ventricle. Females had significantly increases in the following parameters: the width of the anterior horn of the lateral ventricle on the right side and the width of the posterior horn of the lateral ventricle on the left side. Consequently, in male adoles cents a parallelism in the formation of various structures of the ventricular system was traced. Since this is a single system, morphological and functional connections between its different components are stored. Mathematical analysis of the values of the structures of ventricular system in females characterize a hormonal influence on its development in adolescents. We can assume that organs which are the part of the circumventricular system (subcommisural organ, subfornical organ, median rise etc.), definitely have the character of anatomical connections between these components. Their functional unity in maintaining the homeostasis of the body is undeniable.

Dimorphism of both head and prothoracic horn morphologies in male Copris acutidens (Coleoptera: Scarabaeoidea)

AbstractAllometric scaling of male horn morphologies of Copris acutidens, including the head and prothoracic horns, was analyzed. The analyses of scaling relationships indicated a discontinuous increase in head horn length and prothoracic horn height but a linear increase in prothoracic horn length relative to body size. The different results for length and height of the prothoracic horn suggest that the height is functionally more important for ensuring mates in the nests. Furthermore, both the head and prothoracic horns were dimorphic, and this characteristic was not found in the scarabaeoid beetle Onthophagus. Similarity in the switch point values for the head and prothoracic horns suggests that the dimorphism of the two kinds of horns may result from the same developmental threshold mechanism.

Improvement of a rectangle-shape linear piezoelectric motor with four driving feet

To increase the mechanical output ability of a rectangle-shape linear piezoelectric motor with four feet, an improved motor is designed in this study. The improved motor inherits the basic structure of the previous one, but the structure dimensions are adjusted by widening the horizontal beam, shortening the length of the vertical beam׳s uniform part, increasing the length of the vertical horn, and changing the widths of the horns׳ tips. Modal analysis and transient analysis are developed to gain the vibration modes of the motor and the motion trajectories of the driving feet, respectively. After the fabrication of a prototype, its vibration characteristics and mechanical output ability are measured. Experiment results show that a maximum no-load speed of 621mm/s, a maximum thrust force of 11N, and a maximum power of 1.9W are achieved by the prototype. Comparison between the improved motor and the previous one verifies that this study accomplish the design intention of mechanical output ability improvement perfectly.

Reproductive performance of ewe lambs in non-breeding season exposed to hCG at day 12 post mating

The objective of this experiment was to determine the effect of hCG treatment at day 12 post mating on ovarian characteristics, reproductive performance and conceptus growth in ewe lambs induced estrus during the non-breeding season. Corriedale ewe lambs 8 months old were pretreated with progestagen sponges for 10 days and 300IU of eCG. At day 12 post mating, females were treated with either physiological saline (hCG-0; n: 53) or 300IU of hCG (hCG-300; n: 50). Plasma progesterone concentrations were measured at day 17 post mating by radioimmunoassay. Pregnancy was monitored by transrectal ultrasonography on day 40 post mating. At day 41 post mating, 10 ewe lambs of the hCG-0 group and 9 of the hCG-300 group with single pregnancy (randomly chosen) were euthanized and subjected to a morphometric analysis of ovary, uterine and fetal structures. Plasma progesterone levels in the hCG-300 group were significantly higher than those in the control ewe lambs (P<0.05). Pregnancy (49.18% and 46.15%), fertility (60.0% and 56.6%) and prolificacy (1.43 and 1.23) did not differ between the hCG treated and non treated ewe lambs. However, a tendency for a high number of ewe lambs with multiple pregnancies was observed in the hCG-300 group (P=0.08). The percentage of ewe lambs with multiple ovulation was higher in the hCG-300 group compared to the controls (77.8% and 20.0%; P<0.05), while ovary weight and diameters and corpora lutea area did not differ between groups (P>0.05). The length of pregnant horn in ewe lambs of the hCG-300 group showed a tendency to be greater compared with that of the hCG-0 group (P=0.08). Differences were not detected between groups for the uterine weight, number of caruncles and chorionic sac length (P>0.05). Administration of hCG at day 12 post mating increased cranium-caudal length. However, no difference was observed in biparietal diameter and fetal weight between control and hCG treated ewe lambs. Results indicate that hCG treatment did not improve pregnancy rate, prolificacy or fetal weight, however the increase in the plasma progesterone concentration and the percentage of multiple ovulations observed in ewe lambs during the non-breeding season suggest a positive action of this hormone on reproductive performance.

Gross and Biometrical studies of Placentome in Goat(Capra hircus)during Different Stages of Pregnancy

The present study was conducted on the 18 healthy and normal goat uteri of non-descript breed (Capra hircus) varying from day old to 150 days of gestation. The uteri were assigned in to three groups according to their gestational age; Group I (0–50 days), Group II (51 -100 days) and Group III (101-till term). The length, diameter and thickness of gravid horn, non gravid horn, body and cervix were significantly increased with the advancement of pregnancy. Weight of uterus was also significantly increased as pregnancy progressed. The thickness of endometrium, myometrium, perimetrium and total thickness of uterine wall in gravid horn was significantly increased with advancement of pregnancy. The numbers of placentomes ranged from 92 to 153, which were significantly increased from early to mid pregnancy and subsequently significantly decreased during late pregnancy. In the late pregnancy, the placentome were disc like with a shallow depression and had relatively thinner margin. The length, width and thickness of the placentome were significantly increased with the advancement of pregnancy.

External cortical landmarks and measurements for the temporal horn: Anatomic study with application to surgery of the temporal lobe.

Background:The location of the temporal horn is important to neurosurgeons during procedures such as amygdalohippocampectomy and intraventricular electrode placement for temporal lobe seizure monitoring. However, sometimes the temporal horn is difficult to localize, especially without neuronavigation. The authors aimed to better localize this structure using superficial anatomic landmarks.Methods:Twenty-two brain halves were dissected from the midline, and the fornix identified and followed toward the left and right temporal horns. Once the temporal horn was isolated from a mesial approach, 6-cm long needles were placed into its anterior and posterior walls of the temporal horn and passed laterally from the axial plane to the cortical surface. Pin exit sites were marked externally and measurements taken between the outer temporal lobe cortex and the underlying temporal horn.Results:No statistical differences were noted between left and right sides. The temporal horn was generally directed anteroinferiorly and best marked externally by the inferior temporal sulcus. The mean length of the temporal horn was 4.4 cm. Mean distance from anterior temporal tip to anterior wall of the temporal horn was 3.3 cm. The mean distance from the anterior temporal tip to the posterior wall of the temporal horn was 7 cm. The anterior wall of the temporal horn was a mean of 3 mm superior to the inferior temporal sulcus. The posterior wall was a mean of 1.2 cm superior to the inferior temporal sulcus.Conclusions:These landmarks and measurements may help neurosurgeons better localize this part of the lateral ventricular system.

Measures of the ovaries and uterus during development of gilts selected for differences in uterine capacity.

Direct selection for uterine capacity (UC) increased the number of live pigs born. A method to indirectly estimate UC in developing gilts is needed for this trait to be incorporated into commercial selection strategies. We tested the hypothesis that selection for UC alters phenotypic characteristics of the reproductive tract of prepubertal gilts and that these changes could be estimated in live animals using transrectal ultrasound (TRU). Gilts from lines selected for UC and a randomly selected control (CO) line were submitted for TRU at 130, 150, or 170 d of age and harvested 24 h later (n = 10 gilts/line per age). Diameter of the uterine horn was measured (2 to 4 measurements per animal) at TRU. At harvest, measurements of the ovary (height, width, length, weight, and number of visible follicles >1 mm) and uterine horn (weight, length, diameter, and endometrial diameter) were taken. There was no line × age interaction for any of the traits. All ovarian traits increased (P < 0.03) with age. Weight and length of the uterine horn was not different at 130 or 150 d but were increased (P < 0.01) at 170 d of age. Diameter of the uterine horn tended (P = 0.06) to be increased at 170 d compared with 130 or 150 d, but age did not affect (P = 0.38) endometrial diameter. Ovarian weight and width were increased (P < 0.01) and ovarian length and height tended (P = 0.07) to be greater for UC than CO gilts, but the number of visible follicles did not differ. The UC gilts had increased (P < 0.02) weight of uterine horns, which tended (P = 0.09) to be longer than in the CO gilts. Diameter of the uterine horn and the endometrium were greater (P < 0.01) for UC gilts than for CO gilts. Uterine horn diameter measured with TRU was not affected by age or line and was not highly correlated with any of the measured traits. Selection for increased UC results in larger ovaries and uterine horns, but TRU was not useful for estimating these traits in gilts of the age studied.

Feeding prepubescent gilts a high-fat diet induces molecular changes in the hypothalamus-pituitary-gonadal axis and predicts early timing of puberty

ObjectiveThe onset of puberty in females has been occurring earlier over the past decades, presumably as a result of improved nutrition in developed countries. However, the underlying molecular mechanisms responsible for the early attainment of puberty as a result of nutrition fortification remain largely unknown. The aim of this study was to evaluate the hormone and gene expression changes in prepubescent gilts fed a high-fat diet to investigate whether these changes could predict the early timing of puberty. MethodsForty gilts were fed a daily basal diet (LE) or a basal diet with an additional 270 g/d or 340 g/d of fat (HE) during the prepubescent phase. Blood samples were collected during the prepubescent phase to detect hormone secretion changes in insulin-like growth factor-1, kisspeptin, estradiol, progesterone, and leptin. The gene expressions at the hypothalamus–pituitary–gonadal axis were examined on day 73 of the experiment (average age on day 177) during the prepubescent phase. ResultsAn HE diet resulted in accelerated body weight gain and back-fat thickness at the P2 point compared with LE gilts during the prepubescent phase. Gilts that were fed HE diets attained puberty 12 d earlier than LE gilts, and a larger proportion of HE gilts reached puberty at day 180 or 190 of age. A postmortem analysis revealed a promoted development of the uterus and ovary tissue that was characterized by a 53.7% and 29.5% increase in the uterine and ovary weight, respectively, and an increased length of the uterine horn and oviduct tissue in HE gilts. Real-time quantitative polymerase chain reaction revealed that HE gilts had higher Kiss-1, G protein-coupled receptor 54, gonadotropin-releasing hormone and estrogen receptor α mRNA expression levels in the hypothalamic anteroventral periventricular nucleus; the leptin receptor mRNA expression level was higher in the hypothalamic arcuate nucleus and ovary tissue; the insulin-like growth factor-1 receptor expression was higher in the pituitary and ovary tissues, and the follicle-stimulating hormone and luteinizing hormone mRNA expression levels were higher in the pituitary gland. ConclusionThese data showed that the consumption of additional fat can facilitate early attainment of puberty, which can be predicted by the changes in secreted hormones and gene expression in the hypothalamus-pituitary-gonadal axis.

Morphometric Analysis ofOryctes rhinoceros(L.) (Coleoptera: Scarabaeidae) from Oil Palm Plantations

Morphometric analysis was performed on the oil palm pest Oryctes rhinoceros (L.) as part of a study to determine the possibility of a cryptic species complex occurring in this organism. Six beetle populations, each with a sample of 30 individuals, were examined. The morphometric variables measured were total body length, elytral length, pronotal length, pronotal width, and length of the cephalic horn. Principal component analysis and canonical discriminant analysis indicated no distinct discontinuity or clustering of populations. The morphology of individuals from different populations was observed to overlap on one another. These results indicate that O. rhinoceros show stability in morphometric character variance across a wide geographical range.

Realization of Longitudinal-Torsional Complex Vibration by Conical Compound Horn under Single Acoustic Excitation

Realization of longitudinal-torsional complex vibration by conical compound horn has more engineering application value with respect to the conventional longitudinal-torsional complex vibration converting devices. The frequency equations of longitudinal vibration and torsional vibration for the conical compound horn made up of cone and circular cylinder were given based on the wave theory of longitudinal vibration and torsional vibration of ultrasonic horn. The mechanism of the realization of longitudinal-torsional complex vibration by conical compound horn under single acoustic excitation was explained. And a numerical example indicated that longitudinal-torsional complex vibration could be realized by conical compound horn when the length and diameter of such horn were well chosen. The results of this study may be used in the field of longitudinal-torsional complex vibration ultrasonic machining.
