Rathke's cleft cysts: surgical-MRI correlation in 16 symptomatic cases. (1/80)

Rathke's cleft cysts (RCCs) are non neoplastic epithelial lesions of the sellar region that have been rarely reported as a clinical entity. We retrospectively reviewed the magnetic resonance imaging (MRI), intraoperative, and pathological findings of a series of 16 cases of RCCs operated at our institution since 1992. Concurrently, we discussed the different hypotheses about their embryological origin. The patients included 12 females and 4 males, 11 to 73 years of age. Endocrine disturbance was the most common presentation, followed by headaches and visual impairment. The location of the cyst was intrasellar in 7 cases, intrasellar and suprasellar in 6 cases, and suprasellar in 3 cases. The size of the cyst ranged from 8 to 26 mm (mean 12 mm). MRI signal intensity was quite variable on T1-weighted images. The cyst appeared hyperintense in 6 cases, hypointense in 6 cases, isointence in 3 cases, and heterogeneous in one case. On T2-weighted images (available in 13 cases), the signal intensity was more constant and appeared hyperintense in 11 cases and hypointense in 2 cases. After Gd-DTPA, we did not observe enhancement either of the cyst contents or of the cyst wall, but only of the pituitary gland in all patient. Most often, the pituitary gland was displaced inferiorly by the cyst located above showing a typical image of "an egg in a cup". Fifteen patients were operated upon via the transsphenoidal approach and one upon a frontal craniotomy. Intraoperatively, the cyst contents were gelatinous or thick, and dark colored. In 2 cases, it was cerebrospinal fluid-like corresponding to the signal observed on MRI. The position of the pituitary gland confirmed by surgery in 15 cases coincided with enhancement seen and MR imaging. In 13 cases where biopsy of the cyst wall was performed, it confirmed focally ciliated columnar or cuboid epithelium. A coexistent adenoma was found in one case. In conclusion, we consider that RCCs have varied MRI characteristics so that no pathognomonic sign may be observed. Except in few cases, there were no correlation between MRI and intraoperative findings. Therefore, even with MRI studies, differential diagnoses with others cystic lesions of the sellar region remains extremely difficult. The most interesting findings on MRI studies of RCCs were to locate the pituitary gland to help the surgeon to preserve pituitary tissue during surgery.  (+info)

MR imaging findings of Rathke's cleft cysts: significance of intracystic nodules. (2/80)

BACKGROUND AND PURPOSE: Rathke's cleft cysts often may be difficult to differentiate from other intrasellar or suprasellar masses on radiologic studies. The purpose of this study was to describe the significance of intracystic nodules, a diagnostic characteristic found in Rathke's cleft cysts, on MR images. METHODS: A retrospective review of MR studies was conducted for 13 patients who, after pathologic analysis, were diagnosed as having Rathke's cleft cyst. These patients underwent unenhanced and contrast-enhanced T1- and T2-weighted axial and coronal spin-echo sequential imaging. The signal intensity and incidence of the intracystic nodules on T1- and T2-weighted images were analyzed. The signal intensity of the nodule was compared with that of white matter and surrounding cyst fluid. The signal intensity of cyst fluid was compared with the intraoperative appearance of the cyst fluid. Biochemical and pathologic analyses of the intracystic nodules were conducted in two cases. RESULTS: An intracystic nodule having high signal intensity on T1-weighted images and low signal intensity on T2-weighted images was observed in 10 (77%) of the cases. At surgery, intracystic nodules were yellow, waxy, solid masses. Pathologic analysis showed this nodule to be a mucin clump. Biochemical analysis of the intracystic nodules showed cholesterol and proteins as the main constituents. In the Rathke's cleft cyst with intracystic nodules, cyst fluid revealed low signal intensity to isointensity relative to the intensity of the nodules on T1-weighted images, and isointensity to high signal intensity on T2-weighted images. Intracystic nodules were clearly visible on T2-weighted images. CONCLUSION: Because cyst fluid of Rathke's cleft cysts shows variable intensities on MR images, the specific diagnosis is often difficult when based on MR signal intensity values alone. The presence of an intracystic nodule with characteristic signal intensities on MR images may be indicative of the diagnosis of Rathke's cleft cyst.  (+info)

Colloid cysts of the third ventricle: are MR imaging patterns predictive of difficulty with percutaneous treatment? (3/80)

BACKGROUND AND PURPOSE: Colloid cysts of the third ventricle are rare benign brain tumors. The purpose of this study was to correlate their patterns on MR images with the probability of success of percutaneous treatment. METHODS: Nineteen patients underwent endoscopic treatment for colloid cysts of the third ventricle. The cases were divided into two groups based on difficulty of the aspiration procedure. We reviewed CT scans and MR images and divided cysts into groups based on their signal intensity on the MR images and their density on CT scans. Intensity and density were correlated with difficulty of aspiration during the endoscopic procedure. RESULTS: The aspiration procedure was difficult in 63% of the cases. Eighty-nine percent of hyperdense cysts on unenhanced axial CT scans were categorized as difficult, and 75% of hypodense cysts were categorized as easy. On T2-weighted MR sequences, 100% of low-signal cyst contents were difficult and nearly 63% of high-signal lesions were easy. There was a significant correlation between the T2-weighted sequences and the CT scans regarding the difficulty of the aspiration procedure. CONCLUSION: T2-weighted MR sequences are useful for predicting difficulty of aspiration during stereotactic or endoscopic procedures. A T2-weighted low-signal cyst is correlated with high-viscosity intracystic contents.  (+info)

CSF flow studies of intracranial cysts and cyst-like lesions achieved using reversed fast imaging with steady-state precession MR sequences. (4/80)

BACKGROUND AND PURPOSE: Differentiating between intracranial cysts or cyst-like structures and communicating or noncommunicating cysts is often not possible with cranial CT or nonfunctional MR imaging. We evaluated a retrospective ECG-gated fast imaging with steady-state precession (PSIF) MR sequence with optional cine mode to differentiate cystic masses from enlarged CSF spaces and to determine the accuracy of detecting communication between cysts and neighboring CSF spaces. METHODS: Fourteen patients with intracranial cystic masses underwent CSF flow studies with an ungated and a retrospective ECG-gated cine-mode PSIF sequence in addition to spin-echo imaging. Findings were evaluated retrospectively by using a five-point rating scale and without knowledge of clinical or other imaging findings. Results were compared with intraoperative findings or with results of intrathecal contrast studies. RESULTS: Eighteen arachnoid cysts and one enlarged cisterna magna were diagnosed. Improved differentiation between cysts and enlarged CSF spaces was obtained with cine-mode PSIF imaging in six lesions (six patients). Increased diagnostic certainty as to communication between cysts and CSF spaces was obtained in 18 cysts (13 patients). Diagnoses were verified by membranectomy in five lesions, by CT cisternography in five lesions, and indirectly by shunting in one cystic lesion. In one case, MR diagnosis was not confirmed by CT cisternography. CONCLUSION: Cine-mode MR imaging with a retrospective ECG-gated flow-sensitive PSIF sequence contributed to the certainty of communication between arachnoid cysts and neighboring CSF spaces with an accuracy of 90%, using surgical findings or intrathecal contrast studies as reference. Differentiation between intracranial cysts and enlargement of CSF spaces and other cystic masses was improved in 25% of cases.  (+info)

Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and adrenal insufficiency induced by rathke's cleft cyst: a case report. (5/80)

We report a case of a seventy-year-old woman with syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and adrenal insufficiency induced by Rathke's cleft cyst. She experienced nausea, vomiting, diarrhea, and headache and disturbance of consciousness induced by hyponatremia at a serum sodium level of 100 mEq/l. In spite of severe hyponatremia, urinary sodium excretion was not suppressed and serum osmolality (270 mOsm/kg) was lower than urine osmolality (304 mOsm/kg), and arginine vasopressin (AVP) remained within normal range. SIADH was diagnosed because she was free from other diseases known to cause hyponatremia such as dehydration, cardiac dysfunction, liver dysfunction, renal dysfunction, hypothyroidism, and adrenal insufficiency. Cranial computed tomographic (CT) scan and cranial magnetic resonance (MR) imaging showed a cystic lesion of approximately 2 cm in diameter in the pituitary gland. These images suggested that the cystic lesion was a Rathke's cleft cyst, which was the cause of SIADH. Water restriction therapy normalized her serum sodium concentration and improved her symptoms. After one year, she suffered from general fatigue, appetite loss, fever, and body weight loss (5 kg/2 months). She had neither hypotension nor hypoglycemia, but her serum sodium level was low and serum cortisol, ACTH, and urine free cortisol were very low. Therefore, secondary adrenal insufficiency was suspected and diagnosed by stimulation tests. After start of hydrocortisone replacement therapy (10 mg/day), her symptoms disappeared. In conclusion, Rathke's cleft cyst should be kept in mind as a potential cause in a patient with SIADH, hypopituitarism, and/or adrenal insufficiency.  (+info)

Congenital destructive hemispheric lesions and epilepsy: clinical features and relevance of associated hippocampal atrophy. (6/80)

We studied the clinical, EEG and MRI findings in 19 patients with epilepsy secondary to congenital destructive hemispheric insults. Patients were divided in two groups: 10 with cystic lesions (group 1), and 9 with atrophic lesions (group 2). Seizure and EEG features, as well as developmental sequelae were similar between the two groups, except for the finding that patients of group 2 more commonly presented seizures with more than one semiological type. MRI showed hyperintense T2 signal extending beyond the lesion in almost all patients of both groups, and it was more diffuse in group 2. Associated hippocampal atrophy (HA) was observed in 70% of group 1 patients and 77.7% of group 2, and it was not correlated with duration of epilepsy or seizure frequency. There was a good concordance between HA and electroclinical localization. The high prevalence of associated HA in both groups suggests a common pathogenesis with the more obvious lesion. Our findings indicate that in some of these patients with extensive destructive lesions, there may be a more circumscribed epileptogenic area, particularly in those with cystic lesions and HA, leading to a potential rationale for effective surgical treatment.  (+info)

Tentorial enhancement on MR images is a sign of cavernous sinus involvement in patients with sellar tumors. (7/80)

BACKGROUND AND PURPOSE: This study was undertaken to analyze enhancement patterns of the dura around sellar tumors and to compare the results with tumor invasion or compression of the cavernous sinuses. Postoperative enhancement patterns on MR images were compared with preoperative findings. METHODS: Contrast-enhanced coronal and sagittal MR images were examined prospectively in 96 patients with sellar tumors (65 macroadenomas, 15 microadenomas, 14 Rathke cleft cysts, and two chordomas at the sella). All patients underwent surgical treatment, and pre- and postsurgical features on MR images were compared. RESULTS: Presurgical MR images showed dural enhancement in 36.5% of the patients: asymmetric tentorial enhancement in 24 patients, symmetric tentorial enhancement in seven, and sphenoidal ridge or clivus enhancement in four. Asymmetric tentorial enhancement disappeared after surgical decompression in seven patients. For evaluation of cavernous sinus invasion ipsilateral to the enhancement, sensitivity and specificity of the asymmetric tentorial enhancement sign were 81.3% and 86.3%, respectively. Sensitivity and specificity of the sign were 42.9% and 93.6% for cavernous sinus involvement, including compression and invasion. CONCLUSION: Asymmetric tentorial enhancement is a useful sign in the diagnosis of invasion or severe compression of the cavernous sinus by sellar tumor. The sign may represent venous congestion or collateral flow in the tentorium due to obstructed flow in the medial portion of the cavernous sinus.  (+info)

Intramedullary enterogenous cyst presenting with spastic paraparesis during two consecutive pregnancies: a case report. (8/80)

A 35 year old woman presented with two episodes of spastic paraparesis, occurring in the third trimester of two consecutive pregnancies. The neurological symptoms seemed to be caused by an intramedullary cyst in the thoracic spinal cord. The cyst was subtotally removed and histopathologically diagnosed as enterogenous cyst. Other congenital abnormalities were absent. The peculiar timing of the clinical manifestation of an intramedullary cyst has not been described before. An unequivocal explanation for this phenomenon is missing, but several factors related to pregnancy that may play a part are discussed.  (+info)

A Rathkes cleft cyst is a benign growth found on the pituitary gland in the brain, specifically a fluid-filled cyst in the posterior portion of the anterior pituitary gland. It occurs when the Rathkes pouch does not develop properly and ranges in size from 2 to 40mm in diameter. Asymptomatic cysts are commonly detected during autopsies in 2 to 26 percent of individuals who have died of unrelated causes. Females are twice as likely as males to develop a cyst. If a cyst adds pressure to the optic chiasm, it may cause visual disturbances, pituitary dysfunction, and headaches. The majority of pituitary patients with chronic headaches have Rathkes Cleft Cysts. This is believed to be caused by the constant change in volume and the drastic changes in vasopressure from fluctuations in gonadotrophs and ADH. The treatment of choice for symptomatic cysts is drainage and taking a biopsy. Radical excision is more dangerous because of the potential of damaging the patients pituitary function e.g. ADH ...

Rathke cleft cysts (RCCs) are non-neoplastic sellar lesions derived from remnants of Rathke s pouch, and mostly asymptomatic. Symptomatic RCCs occur usually in middle-age, are ,1 cm, and cause pituitary hypofunction, diabetes insipidus, hyperprolactinemia or visual impairment. In children, RCCs are rare and usually asymptomatic. However, symptomatic cases may present with growth retardation and diabetes insipidus. We report two children with symptomatic RCC manifesting as growth retardation.. First case: A 14-year-old boy was admitted because of growth retardation (S.D.S. height −2.5) and delayed puberty. Serum levels of SmC (21 ng/ml), cortisol (4.23 μg/dl), fT4 (0.61 ng/dl) and T3 (0.8 ng/ml) were low, TSH (1.84 μIU/ml) was normal and PRL (2556 μIU/ml) elevated. Stimulation tests of growth hormone (GH) secretion showed low GH (GHmax 1.6 ng/ml). Pituitary MRI revealed an intra- and suprasellar mass 1.2×3.8×2.3 cm with solid and cystic elements. Visual fields were normal. After the start ...

Xanthogranulomatous hypophysitis (XGH) is a very rare form of pituitary hypophysitis that may present both clinically and radiologically as a neoplastic lesion. It may either be primary with an autoimmune aetiology and can occur in isolation or as a part of autoimmune systemic disease or secondary as a reactive degenerative response to an epithelial lesion (e.g. craniopharyngioma (CP), Rathkes cleft cyst, germinoma and pituitary adenomas) or as a part of a multiorgan systemic involvement such as tuberculosis, sarcoidosis or granulomatosis. It may also present with a variation of symptoms in children and adults. Our case series compares the paediatric and adult presentations of XGH and the differential diagnoses considered in one child and two adult patients, highlighting the wide spectrum of this condition. Endocrine investigations suggested panhypopituitarism in all three patients and imaging revealed a suprasellar mass compressing the optic chiasm suggestive of CP or Rathkes cleft cyst in ...

In embryogenesis, Rathkes pouch is an evagination at the roof of the developing mouth in front of the buccopharyngeal membrane. It gives rise to the anterior pituitary (adenohypophysis), a part of the endocrine system. Rathkes pouch, and therefore the anterior pituitary, is derived from ectoderm. The pouch eventually loses its connection with the pharynx giving rise to the anterior pituitary. The anterior wall of Rathkes pouch proliferates, filling most of the pouch to form pars distalis and pars tuberalis. The posterior wall forms pars intermedia. In some organisms, the proliferating anterior wall does not fully occupy Rathkes pouch, leaving a remnant (Rathkes cleft) between the pars distalis and pars intermedia. Rathkes pouch may develop benign cysts. Craniopharyngioma is a neoplasm which can arise from the epithelium within the cleft. It is named for Martin Rathke.

Cystic sellar lesions are a rare cause of hypopituitarism and extremely rare in the pediatric age group. The differential diagnosis is large and includes both primary pituitary abscesses and cystic components on pre-existing lesions, such as adenoma, craniopharyngioma, Rathkes cleft cyst, leukemia, granulomatous disease and lymphocytic hypophysitis. In the absence of a definitive diagnosis, treatment can be challenging. We report a case of a 15-year-old female, who presented with headaches, altered consciousness and diplopia after a molar extraction, for which she had received oral antibiotics. Broad-spectrum i.v. antibiotics were given for presumed meningitis. Blood cultures failed to identify pathogens. Cerebral magnetic resonance imaging showed a pituitary cystic lesion. Endocrine studies revealed abnormal pituitary function.

Pituitary cysts in the pars distalis are frequent incidental findings in rats more than a year old and in mice. Most are remnants of the craniopharyngeal (Rathkes) pouch and are distinct from Rathkes cleft dilation that is localized between the pars distalis and pars intermedia. Pituitary cysts may be single or multiple, may contain eosinophilic proteinaceous or mucoproteinaceous fluid, are often lined by ciliated cuboidal to columnar cells, and typically do not compress surrounding parenchyma. The ciliated epithelial lining may be incomplete. The epithelial lining distinguishes them from angiectasis and/or enlarged vascular sinuses and from cystic degeneration, where irregular edges are lined by degenerating secretory cells. Occasionally, the adenohypophysis contains small follicle-like structures that are incidental and should not be diagnosed as cysts. The presence of multiple epithelium-lined cysts in the pars nervosa (arrows, Figure ...

The increasing recognition of pituitary disorders and their impact on quality of life and longevity has made understanding of this small gland a subject of paramount importance. Pituitary pathology has seen many significant studies that indicate progress in identification and classification of pituitary lesions, as well as improved management strategies for patients. In this review, we outline six major areas of advances: (i) changes in terminology from adenoma to pituitary neuroendocrine tumour; (ii) reclassification of hormone-negative tumours based on transcription factor expression that defines lineage; (iii) updates in new pathogenetic mechanisms, including those that underlie rare lesions such as X-LAG and pituitary blastoma; (iv) clarification of hypophysitis due to immunotherapy, xanthomatous hypophysitis due to rupture of a Rathkes cleft cyst and IgG4 disease as the cause of inflammatory pseudotumour; (v) the consolidation of pituicytoma variants, including spindle cell oncocytoma ...
I read with interest the article by Sener (1), in which he demonstrates a peak at 3.50 parts per million in proton MR spectroscopy of the brain in a patient purported to have van der Knaap syndrome. The peak is interpreted as representing glycine. The author relates this finding to the observation of elevated CSF glycine in patients with van der Knaap syndrome (2).. Regrettably, the author has confused two different disorders of great interest to members of our department: megalencephalic leukoencephalopathy with subcortical cysts (MLC) and vanishing white matter (VWM). The patient described by Sener has MLC, as evident from the clinical course and MR imaging findings (1), whereas elevated CSF glycine has been found in patients with VWM (2). Glycine elevation in the CSF of patients with VWM is, however, far below the level of detection for in vivo MR spectroscopy (2).. Confusion arises from attaching names of authors to diseases, particularly when the same author has contributed to the ...

INTRODUCTION: To clarify whether a three-dimensional-gradient echo (3D-GRE) or spin echo (SE) sequence is more useful for evaluating sellar lesions on contrast-enhanced T1-weighted MR imaging at 3.0Tesla (T). METHODS: We retrospectively assessed contrast-enhanced T1-weighted images using 3D-GRE and SE sequences at 3.0T obtained from 33 consecutive patients with clinically suspected sellar lesions. Two experienced neuroradiologists evaluated the images qualitatively in terms of the following criteria: boundary edge of the cavernous sinus and pituitary gland, border of sellar lesions, delineation of the optic nerve and cranial nerves within the cavernous sinus, susceptibility and flow artifacts, and overall image quality ...

RAWSUBTRACT to subtract numbers without canceling out small roundoff errors. tdf#71459 (Eike Rathke (Red Hat, Inc.)) =RAWSUBTRACT(a,b,c) is like =a-b-c, but the - minus operator cancels out small roundoff errors that are due to the fact that not every decimal number can be exactly represented as a binary floating point number and effectively the operation snaps to zero. RAWSUBTRACT uses the IEEE754 operation the platform/compiler provides. For example, =0.3-0.2-0.1 results in 0, whereas =RAWSUBTRACT(0.3,0.2,0.1) results in 2.77555756156289E-17 .

She presented with the 4.3 cm cyst one year before she came to the USA to see me for non-invasive ethanol ablation.The cyst was only 1 cm when she first presented to with thyroid cancer 4 years prior. Her thyroid function tests including TSH were normal and she had low level TG of 2.1 and TGab of 3.9. She still had thyroid cancer persistence by marker testing. However, my evaluation found ...
My wife has had a branchial cleft cyst for over a year now. When we first had it checked out the Dr. said that it may eventually have to be removed by surgery, if it became inflammed and infected. About three months ago it began to swell and it became very large so we went back to the Dr. and he told her it had to be removed. I began to treat it with herbal decoctions using dandelion root, yarrow, marshmallow root and a couple of different combinations and reduced the swelling dramatically. She got tired of drinking the decoctions so I began just using the capsulized form of the herbs which I dont think is working as well. Its still there but weve been able to keep it down. My question is: Does anyone have any further ideas of what we might do to reduce it even more. For instance detox, or perhaps even some kind of topical application ...
The prevalence of arachnoid cysts in children is 1-3%. They are more frequent in boys. They can be located intracranially or in the spine. Intracranial cysts are classified as supratentorial, infratentorial, and supra-infratentorial (tentorial notch). Supratentorial are divided into middle cranial fossa, convexity, inter-hemisferic, sellar region, and intraventricular. Infratentorial are classified into supracerebellar, infracerebellar, hemispheric, clivus, and cerebellopontine angle. Finally spinal arachnoid cysts are classified taking into account whether they are extra- or intradural, and nerve root involvement ...
We identified 24 previously reported cases in addition to our three cases. Mean age was 36.6 years (range 5-68). There were 16 (59%) females. The most common (74%) presenting symptom was endocrinological deficits, typically either isolated diabetes insipidus (DI) or panhypopituitarism. Location was intrasellar in 3 (11%), suprasellar in 6 (22%), and intrasellar/suprasellar in 18 (67%) patients. Lesions were most commonly (83%) T1 hyperintense. Gross total resection was achieved in 16 (64%) and subtotal resection in 9 (36%) patients. Of the seventeen (63%) patients presenting with varying degrees of bitemporal hemianopsia, all had improvement in vision postoperatively. It is worth noting that no cases of preoperative hypopituitarism or DI improved postoperatively. Even though gross total resection was only achieved in 64%, there was only one recurrence reported. ...
A technique for percutaneous catheter drainage of cystic masses in the subarachnoid space was developed and shown to be safe and effective in an 18-year-old boy with life-threatening, recurrent neuroenteric cysts that compressed the brain stem, cerebellum, and spinal cord. Percutaneous drainage through a C1-C2 approach was performed on 11 separate occasions. Decompression was always accomplished and no infection or other complication occurred, even with continuous catheter drainage for 9 months. This technique provides opportunities for interventional neuroradiologic therapy in the subarachnoid space. It appears to be suited for percutaneous drainage of intraspinal and intracranial cysts when surgery is not indicated due to intractability or inaccessibility. ...

The effect of this cold water swim test was different for lesion and control animals. The levels of estrogen and progesterone are markedly increased in pregnancy and could therefore exert a greater effect on the endothelium of the pyogenic granuloma. Neurenteric or enterogenous cysts are rare, congenital, benign lesions of the central nervous system. Spanish-speaking Mexican-American parents of schizophrenics completed the TAT in their native language, and CD was coded from their stories by a Spanish-speaking rater.

As the result of this early work we find, in reviewing the literature on the subject, that various views were held by these early scientists concerning the sex of the younger embryos during the so-called indifferent period. Many of them considered that the younger embryos represented a stage intermediate between males and females. Others, for example Tiedemann (1813), who is conspicuous for the accuracy of his observations, believed that, because so many more females than males were observed, all human embryos were at first female and that the males resulted from an advance in development over this more primitive condition. The subsequent investigations of Joh. Muller (1830), Rathke (1832), and Bischoff (1842) resulted in but minor additions to the observations of Tiedmann. In fact, Muller considered that the latter were so remarkably complete that additional investigations could not be expected to produce anything new. Ecker (1851-59) published some excellent figures of the external genitalia ...

In: ASA-CSSA-SSSA Annual Meeting Abstracts, Oct. 21-24, 2012, Cincinnati, OH. Available: Interpretive Summary: Technical Abstract: Continuous maize yields are limited by the release of phytotoxic compounds as the previous years maize residue decomposes. We tested the hypothesis that soil biochar applications could help mitigate maize autotoxicity and the associated yield depression. Eighteen small field plots (23.7 m2) were established in Fall 2010 by applying 0 to 112.1 Mg/ha of hardwood biochar and incorporating it to a depth of 30 cm using rotary tillage. The site is on severely eroded Clarion soil with soil quality grading from the poorest in the southwest corner to the best in the northeast corner. A pseudo Latin Squares experimental design was used to account for some of the ...

Th is rare species in Ukraine is found only in two small adjacent localities restricted to the Lower Dnieper. It is characterized by a unique set of chromosomes (2n = 116) and a distinct pool of allozymes, allowing, together with morphological features, to clearly distinguish it from the other three species of the Ukrainian fauna. ...
Theres a tiny spark of optimism in the gloom of this November lockdown. On Monday, Pfizer and BioNTech announced, to everyones surprise, interim analysis showing their vaccine candidate for Covid-19 may have up to 90% efficacy in preventing symptomatic cases of Covid-19 in participants who received two doses three weeks apart. That was based on analysis of 94 confirmed cases of Covid-19 in a trial expected to enrol 44,000 people across the globe.. Experts were cautioning that initial Covid-19 vaccine efficacy could be much lower. The US Food and Drug Association had set its bar for approval at 50% efficacy.. Frustratingly there is little accompanying detail, with the headline data announced by press release, rather than in a peer-reviewed journal, which means less scrutiny than an announcement of this magnitude perhaps needs. The primary goal of the trial, preventing symptomatic Covid-19 infections, will be analysed when cases in the trial reach 164, and its unlikely well see a full data ...
This paper attempts a critical and ethnographically informed reading of the complex assemblage of linkages between migration, racialization and liberal values in modern Greece as a symptomatic case of European attitudes to migration. In line with recent scholarship on racialization and Islamophobia, we discuss novel forms of racism, that support the construction of hierarchies and geographies of entitlement, going beyond notions of biological difference. Processes of inclusion and exclusion, we argue, rest on a meshwork of seemingly disparate identification markers that form the basis of universalist, hegemonic visions of citizenship. Migrants are ultimately expected by considerable sections of the Greek public to demonstrate their acceptance of an array of values regarded as European, and to manifest their support to (neo)liberal regimes of subjectification. We conclude by arguing that racialization can be traced back to an imagined orient, and just as well, to contemporary cultural and ...

  • In some cases, the cysts have been located in brain, eyes or heart tissue. (
  • During Toxoplasma gondii infection, a fraction of the multiplying parasites, the tachyzoites, converts into bradyzoites, a dormant stage, which form tissue cysts localized mainly in brain, heart, and skeletal muscles that persist for several years after infection. (
  • While the long persistence of tissue cysts does not represent a medical problem for healthy individuals, this condition represents a major risk for patients with a compromised immune system, who can develop recrudescent life-threatening T. gondii infections. (
  • We have also demonstrated that complex molecules such as d -luciferin have access to tissue cysts and are metabolically processed, thus providing a rationale for developing drugs that attack the parasite at this developmental stage. (
  • Toxoplasma gondii is transmitted to humans by the ingestion of either undercooked meat containing tissue cysts or poorly washed vegetables contaminated with oocysts from cat feces. (
  • Before being eliminated by the immune system, some of the tachyzoites develop into a dormant stage, the bradyzoites, which multiply at a much lower rate than tachyzoites and become progressively enclosed in a dense matrix surrounded by a thick wall, the tissue cyst ( 11 , 33 , 46 ). (
  • Tissue cysts can persist for several years in the brain, the heart, and the skeletal muscle of individuals who had been previously infected with T. gondii ( 34 , 46 , 49 ). (
  • Tissue cysts do not cause major pathological damage, and parasites are eventually released as result of stochastic reactivation of the bradyzoites ( 14 ) yet are promptly eliminated by the immune system. (
  • However, several conditions may appear later in life that impair the function of the immune system and its ability to control the reactivation of T. gondii tissue cysts. (
  • Reactivation of tissue cysts in these individuals leads to the recrudescence of T. gondii infection ( 15 ), a life-threatening condition that in the long term responds poorly to therapy and often develops into encephalitis ( 16 , 19 , 26 , 28 , 30 , 42 ). (

  • The cysts are fluid-filled sacs, not tumors, appearing in one of the three layers of tissue covering the central nervous system. (
  • During latent infection, bradyzoites are present in tissue cysts. (
  • Transmission to humans usually occurs through the ingestion of oocysts from contaminated sources (e.g., soil, cat litter, garden vegetables, water) or the ingestion of tissue cysts in undercooked meat from infected animals. (
  • These intermediate hosts support the asexual tachyzoite and bradyzoite tissue cyst forms of the parasite. (
  • Human infection may also occur via ingestion of tissue cysts containing bradyzoites in meat from infected animals. (
  • Following human ingestion of either oocysts or tissue cysts, the organism develops into the tachyzoite form which proliferates, infecting host cells and causing their eventual destruction. (
