Abstract:
Abstract Laparoscopy was performed on 6 horses (2 mares, 2 geldings, 2 stallions) to determine the normal laparoscopic anatomy of the equine abdomen. After withholding feed for 36 hours, horses were examined from the left and right paralumbar fossae, and the visceral anatomic structures were recorded by videotape and photography. One mare developed emphysema located subcutaneously at the primary laparoscopic portal; otherwise, there were no complications. The anatomic structures of diagnostic importance that were observed in the left half of the abdomen were the hepatic duct; left lateral and quadrate lobes of the liver; stomach; spleen; left kidney with the associated nephrosplenic ligament; segments of jejunum, descending colon, and ascending colon; left side of the male and female reproductive tracts; urinary bladder; vaginal ring; and mesorchium. Important structures observed in the right side of the abdomen were portions of the common hepatic duct; left lateral, quadrate, and right lobes of the liver; caudate process of the liver; stomach; duodenum; right dorsal colon, epiploic foramen; omental bursa; right kidney; base of the cecum; segments of jejunum, descending colon, and ascending colon; urinary bladder; right half of the male and female reproductive tracts; and rectum.

Abstract:
Abstract Objectives To provide an accurate and detailed description of the laparoscopic anatomy of the abdomen of horses positioned in dorsal recumbency and to compare those observations with laparoscopic anatomy of standing horses. The effects of laparoscopy and positional changes on arterial blood pressure and blood gas values also were investigated. Design Descriptive anatomic study. Sample Population Laparoscopy was performed on 6 horses (2 mares, 2 geldings, and 2 stallions) to record the normal laparoscopic anatomy of the abdomen in dorsal recumbency. Procedure Feed was withheld from all horses for 36 hours. Horses, under general anesthesia, were examined in horizontal and inclined positions (head-up and head-down). Intermittent positive-pressure ventilation was used, arterial blood pressure was continuously monitored, and samples for arterial blood gas measurements were taken at intervals. Results The main structures of diagnostic relevance observed in the caudal region of the abdomen were the urinary bladder, mesorchium and ductus deferens (left and right), left and right vaginal rings, insertion of the pre-pubic tendon, random segments of jejunum and descending colon, pelvic flexure of the ascending colon, body of the cecum, and cecocolic fold. The main structures observed in the cranial region of the abdomen were ventral surface of the diaphragm, falciform ligament and round ligaments of the liver, ventral portion of the left lateral, left medial, quadrate, and right lateral lobes of the liver, spleen, right and left ventral colons, sternal flexure of the ascending colon, apex of the cecum, and stomach. Conclusions Alterations in cardiovascular and respiratory function in response to pneumoperitoneum and various positional changes indicated the need for continuous and throrough anesthetic monitoring and support. Comparison of anatomic observations made in dorsally recumbent, inclined horses with those reported for standing horses should enable practitioners to make patient positioning decisions that best suit access to specific visceral structures. Development of special instrumentation for manipulation of the viscera in horses, particularly the intestinal tract, would increase the diagnostic and therapeutic capabilities of laparoscopy during dorsal recumbency.

Abstract:
The colon of 32 healthy Sprague-Dawley rats was studied microradiographically. The colonic arterial distribution of 18 rats was examined after injecting barium sulfate into the isolated aorta. The mucosal surface in 9 rats was studied using double-contrast technique after colon explantation. In 5 animals arterial and mucosal studies were carried out simultaneously. The radiographic thickness of the colonic wall was measured using a comparative microscope. The specimens were observed, photographed and examined histologically. Unlike the cecum and distal colon which, when insufflated, do not have mucosal folds, the proximal colon exhibits folds in an oblique direction corresponding to that of the arteries, and the colonic wall in this region is thicker. Comparison between arterial and mucosal microradiographic anatomy and wall thickness enables the proposition of a simple nontopographic division of the rat colon into cecum, proximal colon and distal colon.

Abstract:
[Truncated abstract] Clinical and pathological predictors of survival for stage II and III colon cancer patients treated with or without chemotherapy: a population-based study. Aim: Using a population-based cohort of colorectal cancer (CRC), the major aims of this study were to: 1. Identify clinico-pathological markers that can be used to define a subset of stage II colon cancer patients with excellent prognosis and who therefore do not require referral for adjuvant chemotherapy; 2. Investigate whether there is a survival benefit from the use of adjuvant chemotherapy in a population-based cohort of stage II colon cancer; 3. Investigate stage III colon cancer patients for evidence of predictive markers for response to 5FU chemotherapy; 4. Investigate CRC for age-related differences in clinico-pathological and molecular features. Hypotheses to be tested: 1. A subset of good prognosis stage II colon cancers can be defined using routine pathological markers; 2. Females colon cancer patients gain more survival advantage from 5FU chemotherapy than males; 3. Tumours from young CRC patients have different molecular characteristics to those from older patients; 4. The underlying molecular characteristics of tumour can impact upon the response to 5FU chemotherapy. Methods: The study cohort consisted of 5,971 cases diagnosed between 1993 and 2003 representing over 90% of the CRCs diagnosed in the state of Western Australia. Results: The major findings of this translational research into colon cancer can be summarized as follows: The morphological features of serosal and vascular invasion allow for prognostic stratification of stage II colon cancer into

Abstract:
The endocannabinoid system (ECS) is known to be involved in key aspects of cell maintenance within the human colon, as well as being dysregulated in pathophysiological conditions, including colon inflammation and cancer. However, the contribution of the ECS within each of these conditions has not been fully elucidated. This indicates that the current identification of key targets within the ECS that are involved in gut pathology could be used as potential novel therapeutics. Two experimental approaches were designed and optimised to give an insight into ECS signal regulation within the human colon and to screen ECS therapeutics, tetrahydrocannabinol (THC) and cannabidiol (CBD); a human colon ex vivo explant culture model and an innovative multiplexed quantitative gene expression technology, the GenomeLab GeXP system (Beckman Coulter). Gene targets were identified that are known markers of regulation and function in cells of healthy tissue. An assay, the hCellMarkerPlex was designed that incorporated twenty-three of these gene targets, epithelial (EZR, KRT18, SLC9A2), proliferation (PCNA, CCND1, MS4A12), differentiation (B4GANLT2, CDX1, CDX2), apoptotic (CASP3, NOX1, NTN1), fibroblast (FSP1, COL1A1), structural (ACTG2, CNN1, DES), gene transcription (HDAC1), stem cell (LGR5), endothelial (VWF) and mucin production (MUC2). The hCellMarkerPlex identified gene signatures which distinguished between normal, adenoma and carcinoma tissue, identifying cellular processes showing abnormal activity associated with pathological status. The resulting biomarker profiles were used to establish a human colon explant culture system. The human colon explant culture presents a novel model to study modulation of the ECS and screen ECS therapeutics. Combined with the GenomeLab GeXP System multiple components of the ECS were assessed at the gene regulatory level. A custom designed GeXP assay, the hECSplex, was developed. hECSplex gene expression signatures of EC receptors (CNR1, CNR2, GPR55 and TRPV1), ECS enzymes (NAPE-PLD, GDE1, DAGLA, DAGLB, FAAH, FAAH2 and PTGS2), inflammatory (IL1B, IL10, IL6, LEP, TNF and SOCS3), signalling pathway (ID1, BCL2, CFL1, BIRC5, TP53, MYC and KRAS), lipid production (SREBF1, ACACA), and plasma-membrane (OCLN) markers revealed altered expression of ECS components in carcinogenesis compared to normal tissue. Abstract vi . The hECSplex gene expression signature of colon explants showed that ECS was not altered during culture, emphasising the explant models capability as a pharmaceutical tool to test current and novel therapeutics. Applications of both THC and CBD to normal colon explants at different concentrations do not lead to any significant changes. Indicating the current pharmacological use of phytocannabinoids is causing no adverse effects in surrounding healthy colon tissue. The GenomeLab System presents new opportunities to interrogate multiple components of the endocannabinoid signalling system in small colon explant tissue samples, and in response to ECS therapeutics.

Abstract:
Purpose/Objective: Cervical cancer is the third most common cancer in women worldwide. Definitive chemoradiation is the accepted standard of care for patients especially for locally advanced cervical cancers. Intracavitary brachytherapy (ICBT) is an important part of definitive radiotherapy shown to improve overall survival. Interstitial brachytherapy (ISBT) is generally reserved for patients either with extensive pelvic and/or vaginal residual disease after external beam radiotherapy (EBRT) or with anatomy not allowing ICBT with standard applicators in an attempt to improve local control. We have conducted an observational study for patients who underwent image guided HDR-ISBT at our institute. Materials and Methods: Seven patients; diagnosed as a case of carcinoma cervix; were selected from the period of 2012 to 2015 who received EBRT by IMRT and for whom ICBT couldn’t be done for various reasons. These patients were then taken up for Martinez Universal Perineal Interstitial Template (MUPIT) image based ISBT. A descriptive analysis was done for doses received by HRCTV, bladder, rectum and sigmoid colon. At the end of treatment, early response at 3 months along with overall survival (OS) and disease free survival (DFS) was also calculated. Results: All the patients recruited were locally advanced with 3 patients in IIB, 1 patient in IIIA and 3 patients belonging to IIIB. The mean dose received by 95% high risk CTV (HRCTV) by IMRT was 49.75 Gy. Out of 7 patients, 3 were taken up for ISBT due to anatomical restriction whereas remaining 4 patients were included because of lack of dose coverage by ICBT. The mean doses received by 90% of HRCTV, 2 cc bladder, 2 cc rectum and 2 cc sigmoid colon were 20.58 Gy, 2.73 Gy, 3.19 Gy and 2.82 Gy respectively. The early response at 3 months was 57.14%. The DFS at one year and OS at 3 year were 53.6% and 53.3% respectively. Conclusions: Our descriptive analysis of seven patients being treated by image based ISBT have revealed that locally advanced cervical cancer patients for whom ICBT is unsuitable can achieve equitable LRC and OS with a combination of EBRT by IMRT and image based HDR-ISBT.

Abstract:
The goal this reviews was to determined the influence of the diet on digestive system in the birds and roles of digestive tract. Birds have a very complex digestive system, which is thought to have a significant impact on how well they utilize the nutrition that they consume. It is expected that the stomach, intestines, cecum, proventriculus, and gizzard of herbivorous birds will be larger than those of carnivorous birds, whereas herbivorous birds tend to have longer, more complex digestive tracts. This may be due to herbivorous require high time and energy to the breakdown of cellulose. Their digestive processes were described for birds with different diets.. The proventriculus' size impacted by the diet, not the intestines, gizzard, or cecum. Insectivores had the largest proventriculi, whereas herbivores had the smallest, and omnivores had a proventriculus of a medium size. The function of the avian digestive organs in regulating the gut bacteria, fermenting unabsorbed nutrients, recycling nitrogen from urine, and maintaining gut health. Through aiding food uptake, and interactions with the immune system, gastrointestinal microbiota play a crucial role in maintaining organism health. Only tiny and/or soluble particles, along with digestive juices and urine, will reflux into the caeca due to anatomical and physiological adaptations. Salts and water will be reabsorbed here, and the rich bacteria will ferment uric acid and carbohydrates into ammonia and volatile fatty acids. The caeca may thereby affect the bird's nutritional health. Starch and proteins can be consumed, stored, and partially digested in the early section of the avian digestive system. With the exception of the absence of lacteals, the avian gut has a comparable anatomy to other monogastric animals. The microvilli in the avian intestine are covered by a noticeable glycocalyx. The mammalian liver's actual lobular structure is absent from the avian liver. Around the bile caniculi, hepatocytes are organized in plates two layers thick of cells. Acinar cells, that produce digesting enzymes to the pancreatic ducts, endocrine cells, that secrete hormones to the bloodstream, are found in the two main lobes and two smaller lobes of the avian pancreatic structure. The colon structure is similar to that of intestine except the poor enervation.

Abstract:
Introduction: Locally advanced carcinoma cervix includes stages IIB, IIIA, IIIB and IVA. Interstitial brachytherapy has the potential to deliver adequate dose to lateral parametrium and to vagina. Hence, it is preferable in cases with distorted anatomy, extensive (lower) vaginal wall involvement, bulky residual disease post EBRT and parametrium involvement upto lateral pelvic wall. Aim and Objective: To determine clinical outcome and complications (acute and chronic) in locally advanced carcinoma cervix, treated with interstitial brachytherapy using template (MUPIT - Martinez universal perineal interstitial template). Materials and Methods: This study is a retrospective analysis of 37 cases of locally advanced carcinoma cervix (stage IIB-2, IIIB-30, IVA-5), treated with EBRT (dose-median 45Gy/25#) ± concurrent chemotherapy (CCT) - Inj. Cisplatin/Inj Carboplatin, followed by interstitial brachytherapy using MUPIT from December 2009 to June 2015. Initial treatment with EBRT ± CCT was followed by intertstitial brachytherapy. Under spinal anaesthesia and epidural analgesia, MUPIT application was done. Straight and divergent needles (median 26, range 19-29) were inserted to cover parametrium adequately. Needle position was verified with planning CT scan and Brachytherapy planning was done. Dose was normalized to 5 mm box surface from outermost needle with optimization of dose to OAR (Bladder, Rectum and Sigmoid colon). Prescription dose –25Gy in 5#. Treatment was delivered by Microselectron HDR using Ir192 source. Treatment fractions were delivered twice daily with min 6 Hrs. gap in-between fractions. Results: The median duration of follow-up was 25 months. Local control was achieved in 28 patients with residual disease in 7 patients and local recurrence in 2 patients. 10 patients had acute lower GI toxicity {Grade1 (n=6), Grade 2 (n=4)}, 2 patients had acute Grade 1 bladder toxicity. 1 patient had grade 3 and 1 patient had grade 4 chronic bladder toxicity. Chronic rectal toxicity was seen in 10 patients {Grade 2 (n=4), Grade 3 (n=4), Grade 4 (n=2)}. Conclusion: Local control was achieved in 28/37 patients (75.6%) and overall survival rate of 81.1% at median follow up of 25 months in patients with locally advanced carcinoma cervix and unfavorable prognostic factors.

Abstract:
Cases of cerebral achromatopsia have increased our understanding of the anatomy of extrastriate cortex. Some features of the reported cases have not so far been explained: for example, 1) Why can some but not all patients read pseudoisochromatic plates? 2) Why do some patients have a relatively greater impairment of short wavelength mechanisms? Results obtained in four cases of cerebral achromatopsia will be presented in an attempt to address these and other issues. One patient showed a marked deterioration in both chromatic processing and achromatic contrast sensitivity at low light levels, suggesting that the testing conditions may be important. In some cases dynamic random luminance masking (which disables achromatic mechanisms) results in a total failure of chromatic discrimination, while in others this has no effect on residual color discrimination. Thus the extent to which discrimination depends upon residual chromatic or achromatic mechanisms may vary. In one case it has been shown by using incremental threshold techniques that S-cone sensitivity may be reduced by 1.5 log units in the presence of near normal L-cone sensitivity, suggesting that the relatively greater impairment of short wavelength mechansisms is reflected in detection thresholds as well as chromatic discrimination. These differences in residual vision are discussed in the context of the underlying anatomy.

Abstract:
Cone and ganglion cell densities fall rapidly with eccentricity from the fovea. But the decline is not symmetrical: cell densities decrease more rapidly on the temporal retina. We examined the implications of this spatial organization for color vision. Spectral lights were presented along the horizontal meridian from 40° nasal to 40° temporal. Several stimulus sizes were used to identify the minimal size for best color vision at each retinal locus. Color vision was assessed by means of hue and saturation scaling. Multidimensional scaling was then used to derive uniform appearance diagrams from the data. These diagrams illustrate the color spaces associated with each size-location combination; we also derived discrimination functions from them. As expected from retinal anatomy, peripheral stimuli had to be progressively enlarged to maintain a full range of saturated hues; this enlargement had to be greater in temporal retina to produce comparable sensations to those from the corresponding nasal locations. Small stimuli produced restricted color spaces akin to those of tritanlike deficits. Variations in cone destiny alone cannot account for the changes in color vision across the visual field.

Abstract:
The standard procedure for fluid preservation of insects consists of two steps. First, the specimen is killed and prepared in a fixative fluid and then transferred to a storage fluid. Recommendations for using specific chemicals or mixtures differ depending on the size and anatomy of the animal and vary among the authors. However, controlled comparative studies are often missing. The ideal method should preserve the specimen�s morphology as well as its genetic information. We have investigated the effect of 12 combinations of commonly used methods based on ethanol, using four types of fixatives (Hot Water Kill (HWK) for 5 minutes/6 hours; absolute ethanol cold/boiling) and three types of storage fluids (70 %; 80 %; and absolute ethanol) after eight months of storage. The effects were tested on mature larvae of a forensically relevant beetle species. We have evaluated the effectivity in terms of color preservation, shape of the specimen, and quality of genetic material. The color was best preserved by HWK for 5 min with subsequent storage in absolute ethanol, and the worst results were achieved by cold absolute ethanol with subsequent storage in 70 % ethanol. The fixative type has a major effect on the shape compared to the storage fluid. The effect of treatments on shape appears to be inverse to the effect on color preservation. The genetic material was preserved equally well in all treatments. The advantages and disadvantages of specific treatments and the recommendation of the best method are discussed.

Abstract:
Introdução: O hímen é uma estrutura de tecido escamoso que se inva-gina do períneo para encontrar o canal vaginal longitudinal. Com essa jun-ção, geralmente há canalização completa do canal vaginal, e essa membrana retrai-se com apenas um pequeno remanescente de tecido circunferencial redundante ao redor do introito vaginal. No entanto, durante esse processo de canalização, a membrana pode variar em sua resolução, deixando uma obstrução completa, hímen imperfurado ou qualquer número de remanes-centes parciais, como o hímen microperfurado e septado. Relato de caso: E.B.M., 22 anos, estudante de Medicina, procura ambulatório em razão de dificuldade na sexarca há dois anos. Já fez diversas tentativas de penetração vaginal com o parceiro, sem sucesso. Refere ter tido relação com penetra-çã o anal, sem grandes dificuldades. Menarca aos 11 anos, ciclos regulares com fluxo normal. Parceiro único. Faz uso de venlafaxina para transtorno de ansiedade. Traz hipótese diagnóstica de vaginismo, de acordo com leituras na internet. Já procurou outro médico para tratar vaginismo, que orientou fisio-terapia pélvica. Ao exame: mamas e abdome sem alterações. Pilificação vul-var normal. Toque vaginal: membrana himenal perfurada, pérvia para 1 cm, com bordos rígidos e resistentes. Sem dor ou tensão muscular no momento do toque. Colo uterino indolor à mobilização, útero intrapélvico. Toque retal sem alterações. É, então, realizada cirurgia de himenectomia com o seguinte resultado anatomopatológico: fragmento membranáceo de tecido pardo acin-zentado e cruento medindo 2,5 × 2 × 0,4 cm. Cortes histológicos da mucosa himenal mostram epitélio escamoso não queratinizado, maturação sequencial preservada, sem atipias celulares. O estroma subjacente aparece com discreto infiltrado inflamatório linfocitário. Após 45 dias pós-operatório, a paciente relata relação vaginal com parceiro, sem dificuldades. Conclusão: O vagi-nismo é uma persistente contração involuntária da musculatura da vagina que interfere na penetração, impedindo a relação sexual e podendo compro-meter as relações interpessoais e conjugais. A paciente estudada apresentava transtorno de ansiedade, o que contribuiu para a hipótese diagnóstica de vagi-nismo. Além disso, observa-se a influência da internet na saúde, que levou a paciente a se autodiagnosticar e a enviesar a opinião do primeiro médico. Entretanto, o exame ginecológico mostrou importante anatomia himenal atí-pica, que impossibilitava a penetração. O caso reforça a importância da anam-nese e exame físico ginecológico bem realizados. O hímen pode apresentar-se de diferentes formas, tais como imperfurado, microperfurado, cribiforme e septado. A himenectomia é um procedimento cirúrgico que objetiva a remo-ção da membrana himenal que cobre parcial ou totalmente o introito vaginal. O caso foi identificado como hímen microperfurado e a cirurgia permitiu a resolução completa da queixa da paciente.

Abstract:
This paper explores the politics of repression and coercion in Belarus, with a focus on the Belarusian authorities’ brutal responses to dissident activities. While repressions are seen to be a backbone of authoritarian rule, there is a lack of case studies of repressions and repressive policies in different kinds of authoritarian regimes and their interaction with other mechanisms of authoritarian sustainability. As Belarus has demonstrated, Lukashenko’s effort’s at perpetuating his power have prompted his regime into increasing the role of repressions. Coercion and repression have been critical to suppressing dissent and pluralism across the country. Essentially, successful, mass-based opposition to the ruling elites, that led to 2014 Maidan Revolution in Ukraine and the 2018 “Velvet Revolution” in Armenia served as examples to discontented elements in Belarus. Meanwhile, to shield itself from the diffusion effects of ‘color revolutions’, the Belarusian regime has tended to reinforce its repressive toolkit through suppressing the civil society, coercing the opposition, and preventing the latter from challenging Lukashenko’s rule. This study enquires into the anatomy of repressive governance in Europe’s “last dictatorship.”
