We show that most arithmetic circuit lower bounds and relations between lower bounds naturally fit into the representation-theoretic framework suggested by geometric complexity theory (GCT), including: the partial derivatives technique (Nisan–Wigderson), the results of Razborov and Smolensky on AC[p], multilinear formula and circuit size lower bounds (Raz et al.), the degree bound (Strassen, Ba...

Aim. Investigate the disruption of geniculocalcarine tract (GCT) in different occipital neoplasm by diffusion tensor imaging (DTI). Methods. Thirty-two subjects (44.1 ± 3.6 years) who had single occipital neoplasm (9 gliomas, 6 meningiomas, and 17 metastatic tumors) with ipsilateral GCT involved and thirty healthy subjects (39.2 ± 3.3 years) underwent conventional sequences scanning and diffusi...

Growing evidence points toward the key role of angiogenesis in ovarian cancer. Granulosa cell tumor (GCT) does not seem to be an exception. Recent studies reporting the use of bevacizumab, a monoclonal antibody against the vascular epithelial growth factor, in recurrent GCT have shown encouraging results in terms of both symptoms control and response rate. This study presented the case of an ad...

Objectives: The present study aimed to compare the diagnostic values of glycosylated hemoglobin (HbA1c) and fasting blood sugar (FBS) using glucose challenge test (GCT) in screening for gestational diabetes. Materials Methods: A total 618 women at 24-28 weeks pregnancy were selected, their FBS HbA1c measured GCT. obtained results compared terms sensitivity, specificity, as well positive negativ...

Giant cell tumour of bone (GCT) is a benign primary neoplasm of a bone characterised by distinctive clinical, radiological and pathological features. Females are slightly more often affected than males, and the majority of patients present between the ages of 20 and 50. GCT is locally aggressive and produces expansive and lytic lesions, most commonly in the epiphyses of long tubular bones. Hist...

OBJECTIVE We examined the association between 1-hour glucose challenge test (GCT) values and risk of caesarean section. STUDY DESIGN A prospective cohort study recruited 203 pregnant Black women to participate. At ~28 weeks of gestation, participants underwent a routine 1-hour 50 g GCT to screen for gestational diabetes mellitus. Logistic regression was used to examine the association between...

Background. Granulosa cell tumors (GCTs), representing ~2% of ovarian tumours, are poorly understood neoplasms with unpredictable and undetermined biological behaviour. Design. 5 unusual presentations of GCT and a retrospective 14-year (1997-2011) surgical pathology review based on patient sex, age, tumour type and concurrent pathology findings are presented to discuss the "myths and realities"...

Introduction: Giant cell tumor (GCT) is a benign but locally aggressive that accounts for 4% of all primary bone tumors. The distal radius the third most common site GCT, after femur and proximal tibia. Wide excision one treatment options this can create defect at end radius. tumors (GCTs) occur in are likely to recur. recurrent GCTs very challenging. We report our clinical experience using fib...

Giant cell tumour (GCT) is an uncommon primary bone tumour, and its multicentric presentation is exceedingly rare. We report a case of a 45-year-old female who presented to us with GCT of left distal radius. On the skeletal survey, osteolytic lesion was noted in her right sacral ala. Biopsy confirmed both lesions as GCT. Pulmonary metastasis was also present. Resection-reconstruction arthroplas...

IntroductIon Granular cell tumor (GCT) of neurohypophysis was first reported by Boyce and Beadles in 1983.[1] In 2016 WHO classification of central nervous system (CNS) tumors, GCT of neurohypophysis was defined as a distinct diagnosis.[2] Here, we reported two cases of GCT of neurohypophysis misdiagnosed as pituitary adenoma and craniopharyngioma. One of the cases was a very rare fully describ...
