Abstract
Background and Aim: The extent of resection seems a solid prognostic factor in patients with high-grade gliomas (HGGs). When administered orally, 5-aminolevulinic acid (5-ALA) is exclusively converted into protoporphyrin IX (PPIX) by malignant cells and detects, identifying contrast-enhancing glial lesions under 400 nm blue light. The authors thoroughly assess the efficacy, accuracy, and safety profile of 5-ALA-guided surgery toward the maximal resection of cranial HGGs. Case Presentation: Thirty consecutive patients with HGG adjacent to the corticospinal tract (CST) met our inclusion criteria in a single-arm retrospective study. Bilateral diffusion tensor imaging (DTI)-derived corticospinal tract (CST) tractography was employed using a 1.5 Tesla magnetic resonance imaging (MRI). Oral 5-ALA was ingested with a dose of 20 mg/kg 4 hours prior to operation and was applied to qualify the margins of the local resection cavity. The clinical and volumetric assessments were postoperatively conducted. The mean preoperative tumor volume on T1 contrast-enhanced MRI and fluid-attenuated inversion recovery (FLAIR) images was 16.8 cm3 and 47.6 cm3, respectively. Complete resection of contrast-enhanced lesions was yielded in 27 of 30 patients (90%). All patients improved postoperatively regarding motor deficits and or seizures. No new permanent neurological deficits were detected in the 3-month follow-up. Conclusion: Fluorescence image-guided surgery (FIGS) using 5-ALA increases the extent of resection (EOR) with further surgical risks in eloquent regions when combined with multimodality visualization- functional mapping. It also provides pathological insights to visualize cranial HGGs and identify infiltration of functional fiber tracts.

Abstract
The COVID-19 pandemic has accelerated neurological, mental health disorders, and neurocognitive issues. However, there is a lack of inexpensive and efficient brain evaluation and screening systems. As a result, a considerable fraction of patients with neurocognitive or psychobehavioral predicaments either do not get timely diagnosed or fail to receive personalized treatment plans. This is especially true in the elderly populations, wherein only 16% of seniors say they receive regular cognitive evaluations. Therefore, there is a great need for development of an optimized clinical brain screening workflow methodology like what is already in existence for prostate and breast exams. Such a methodology should be designed to facilitate objective early detection and cost-effective treatment of such disorders. In this paper we have reviewed the existing clinical protocols, recent technological advances and suggested reliable clinical workflows for brain screening. Such protocols range from questionnaires and smartphone apps to multi-modality brain mapping and advanced imaging where applicable. To that end, the Society for Brain Mapping and Therapeutics (SBMT) proposes the Brain, Spine and Mental Health Screening (NEUROSCREEN) as a multi-faceted approach. Beside other assessment tools, NEUROSCREEN employs smartphone guided cognitive assessments and quantitative electroencephalography (qEEG) as well as potential genetic testing for cognitive decline risk as inexpensive and effective screening tools to facilitate objective diagnosis, monitor disease progression, and guide personalized treatment interventions. Operationalizing NEUROSCREEN is expected to result in reduced healthcare costs and improving quality of life at national and later, global scales.

Abstract
BACKGROUND The immune system significantly participates in the development of the successful delivery process. The roles played by cytokine molecules in the induction of term delivery are yet to be clarified. The aim of this project was to explore the serum levels of interleukin-10 (IL-10), IL-17A, and IL-23 in the mothers with term and prolonged pregnancy and their infants. MATERIALS AND METHODS In this study, 60 samples were collected from either mothers with term and prolonged pregnancy or their infants, collectively 240 samples. Serum levels of IL-10, IL-17A and IL-23 were explored using enzyme linked immunosorbent assay (ELISA) technique. RESULTS IL-10 serum levels significantly decreased in the neonates with prolonged pregnancy when compared to their mothers. Serum levels of IL-23 were increased either in term or prolonged pregnancy neonates when compared to their corresponded mothers. Serum levels of IL-10 and IL-23 significantly decreased and increased, respectively, in the female in comparison to male in the prolonged pregnancy neonates. IL-10 also significantly decreased in the term mothers who had higher gravidity. CONCLUSION Although, IL-17A does not play a key role in the delivery mechanism, IL-10 and IL-23 may be considered as potential factors in the modulation of term delivery.

Abstract
The rectus abdominis muscles are interrupted by tendinous inscriptions, which typically appear as fibrous bands crossing the muscle. The current literature on tendinous inscriptions is scarce; hence, this review will provide a detailed overview of their anatomical description, including their variation, embryology, comparative anatomy, and clinical application. Understanding the anatomy and function of the tendinous inscription assists in providing clinical relevance and in guiding reconstructive surgeons in their surgical planning and design.

Abstract
Abstract
BACKGROUND: Pineal region tumors are rare intracranial tumors that are more common in children than adults. Surgical management of tumors in this region using a tailored approach is a strategy that enhances extent of resection and neurological outcome.
OBJECTIVE: To review our institutional experience with pineal region tumors in children and adults over the past 10 years.
METHODS: Our institutional pathology database and patient records were retrospectively reviewed for details regarding clinical and radiological presentation, surgical management, extent of resection, morbidity, and neurological outcome. Statistical analysis was performed to assess for variables related to functional outcomes.
RESULTS: Fifty patients were identified as having undergone surgical management of a pineal region tumor with at least 1 year of follow-up. Forty-one percent presented with a Karnofsky Performance Scale (KPS) score of 70 or less, all of whom had concomitant hydrocephalus that required urgent treatment. The following variables were statistically significant to KPS score on admission: age, tumor volume, preoperative hydrocephalus, length of hospitalization (total and intensive care unit), and elevations in serum tumor markers. The median postoperative (2 months) KPS score was 90. The following variables were statistically significant with respect to change in KPS score postoperatively: tumor maximum diameter, KPS score on admission, and intensive care unit length of stay. The specific surgical strategy did not correlate to extent of tumor resection, morbidity, immediate neurological outcome, and progression-free survival.
CONCLUSION: Extent of resection, neurological outcome, and progression-free survival in the patients in our series were not related to the specific surgical approach employed and its perioperative complications.

Abstract
Julius Casserius was born in a poor family in Piacenza in 1552. As a young man, he moved to Padua and soon after, he became a servant to Fabricius, a noted anatomist and professor at the Universitá Artista, who quickly became his mentor. Casserius eventually attended the University of Padua and received a degree in medicine and philosophy. In the following years, a rivalry ensued between Casserius and his former mentor as they competed for teaching privileges, conflicted on dissection philosophies, and disregarded each other's contributions in publications. Tragically, the conflict between these two influential anatomists may have overshadowed their contributions to the study of anatomy. Casserius was one of the first physicians to develop a comprehensive treatise on anatomy. Unfortunately, while Casserius prepared several tracts identifying novel structures, he did not live to see his master collection published as he died suddenly at the peak of his career in 1616. Interestingly, the English anatomist and surgeon John Browne used copies of Casserius' work for his own anatomy text and was labeled a plagiarist. It is the contributions from such pioneers as Casserius on which we base our current understanding of human anatomy.

Abstract
BACKGROUND To optimize dialysis prescription and fluid balance of the peritoneal dialysis (PD) patients, it is important to assess their dry weight accurately. The experimental evaluation is the method which is widely used in PD centers which needs continuous and controlled reduction of the postdialysis weight down to the point where patient does not show any signs of hypotension and volume overload. This study intends to indicate that the bioelectrical impedance analysis (BIA) method can be used as an alternative method to evaluate the dry weight. MATERIALS AND METHODS The demographic data of 101 continuous ambulatory peritoneal dialysis (CAPD) patients of Alzahra and Noor hospitals of Isfahan University (50 males and 51 females) who had been referred for periodical examinations from April 2009 to April 2010 were extracted from their files. The normal body volume was selected as the inclusion criteria and identified by an examiner group (a nephrologist, a general practitioner and a PD nurse). The patients' dry weights were calculated based on both methods. The bioelectrical impedance analysis method was done by the Maltron Bioscan ver916 and data were analyzed by SPSS program ver18. RESULTS There were 49.5% males and 50.5% females with the mean age of 54.6±17 years. The mean dry weight in the experimental method was 63.4±13.3 kg in comparison to the other (61.5± 13.7 kg). There was a significant difference between the results (P value <0.001) depended on the gender t-test, but there was a 98% correlation between the results by two methods. No correlation observed between the patient's age, body mass index, blood pressure, previous hemodialysis history, PD duration time, and underlying disease. CONCLUSION The study showed that there is significant difference between the two methods. However, there was 98% direct correlation between them. It is concluded that bioelectrical impedance analysis could be a better alternative for accurate evaluation of dry weight in PD patients because it is a fast and cheap method and does not depend on examiner's capability. Further studies based on the results of this method are recommended to consider this method as the gold standard.

Abstract
Manuscript submitted May 23, 2011. Accepted September 25, 2011. Kenneth Grant Jamieson is celebrated as one of Australia's top neurosurgeons. His most notable contributions to neurosurgery included novel treatments of aneurysms and pineal tumors and studies of head injury. Jamieson was also an innovator for the development of new neurosurgical instruments and renowned for his teaching abilities, prolificacy, and mentorship. This preeminent neurosurgeon's life was cut short at the age of 51. Our current understanding and knowledge of treatments of various neurosurgical diseases is based on pioneers such as Kenneth Grant Jamieson.

Abstract
The aim of this study was to investigate the antiproliferative proteins that probably have a role in Helicobacter pylori evade of immune response and cause chronic infection disease and also to see if coccoid form had a role in its chronicity. H. pylori strain VacA s2/m2 positive and CagA negative, from a gastric biopsy of a patient with peptic ulcer disease, was isolated and cultured in brucella agar. Both spiral and coccoid forms were harvested and ruptured by sonication. The cytoplasmic solutions of both forms were collected and their fractions obtained by gel chromatography and preparative polyacrylamide gel electrophoresis. The fractions were analyzed by MTT assay for their antiproliferative activity. We isolated two proteins with a significant dose dependent antiproliferative activity that analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis, one of them that was urease positive showed two bands with 61 and 27 kDa, which is resumed to urease of H. pylori, another consist of 57 and 63 kDa. Helicobacterpylori secret some proteins like urease that inhibit immune cells proliferation response against its antigens.

Abstract
A low-temperature hydrogenation-assisted sequential deposition and crystallization technique is reported for the preparation of nano-scale silicon quantum dots suitable for light-emitting applications. Radio-frequency plasma-enhanced deposition was used to realize multiple layers of nano-crystalline silicon while reactive ion etching was employed to create nano-scale features. The physical characteristics of the films prepared using different plasma conditions were investigated using scanning electron microscopy, transmission electron microscopy, room temperature photoluminescence and infrared spectroscopy. The formation of multilayered structures improved the photon-emission properties as observed by photoluminescence and a thin layer of silicon oxy-nitride was then used for electrical isolation between adjacent silicon layers. The preparation of light-emitting diodes directly on glass substrates has been demonstrated and the electroluminescence spectrum has been measured.

Abstract
Hua Tuo (c. 108-208 AD), the Chinese surgical pioneer and herbal expert, excelled as a physician, making significant strides in anesthesia, surgery, and acupuncture. He is accredited for spearheading the practice of laparotomies and organ transplants, using anesthetics, and he was the first Chinese surgeon to operate on the abdomen including performing splenectomy and colostomy. Neurologically, Hua Tuo is said to have performed procedures to treat headache, paralysis, and suspected a brain tumor in one patient. Tuo's impact on medicine was so profound that the phrases "A Second Hua Tuo" or "Hua Tuo reincarnated" were coined in honor of his diligence and compassion to recognize outstanding physicians who demonstrate an equal caliber of surgical competence. It is the pioneering contributions to medicine and surgery as made by such physicians as Hua Tuo on which we base our current understanding.

Abstract
Emanuel Swedenborg is widely accredited for his religious fervor and devout dedication to his spirituality. He spearheaded the creation of what is known today as the New Jerusalem Church. However, Swedenborg also served as a prominent figure in the European Enlightenment, making noteworthy strides in the fields of mathematics and science. His acumen for science instilled in the medical world groundbreaking ideas that would forever innovate the practice of medicine. Not only did Swedenborg describe intricacies of the cerebral cortex but he also discovered the perivascular spaces, the foramen of Magendie, and the cerebrospinal fluid. He noted the importance of the pituitary gland or "arch gland" in maintaining normal neurological function. Lastly, in a period where the cortex was given no significant function, Swedenborg developed the idea of somatotopic organization, and this was almost 100 years prior to Fritsch and Hitzig. It is on the shoulders of such great pioneers as Emanuel Swedenborg that we base our current understanding of the nervous system.

Abstract
The specialized ligaments of the craniocervical junction must allow for stability yet functional movement. Because injury to these important structures usually results in death or morbidity, the neurosurgeon should possess a thorough understanding of the anatomy and function of these ligaments. To the authors' knowledge, a comprehensive review of these structures is not available in the medical literature. The aim of the current study was to distill the available literature on each of these structures into one offering.

Abstract
Streptomyces griseoflavus PTCC 1130 was mutated by UV irradiation. Two mutants were obtained (C7031 and S7011). These two mutants were able to produce desferioxamine. Desferrioxamine was extracted from the culture broth of the two mutated strains and the thin layer chromatogram of the products showed the R(F) values of 0.461, 0.463 and 0.456 for S7011, C7031 and the standard, respectively. The protoplasts of mutated Streptomyces griseoflavus were isolated and fused together. Total numbers of 58 fusions were obtained and only 17 fusions showed significant resistance to sodium azide and crystal violet. In terms of production of desferrioxamine only fusion PF9 and PF10 increased 68.3 and 81.8% desferrioxamine production as compared to parent strain (PTCC 1130), respectively.

Abstract
OBJECTIVE We sought to determine the prevalence of cardiovascular disease and risk factors among chronic renal failure (CRF) patients on the transplantation waiting list. METHODS Fifty CRF patients on chronic hemodialysis who underwent evaluation for transplantation were compared with 60 hypertensive patients matched for age. We used Framingham scoring to calculate the absolute risk; relative risk was calculated based on the low-risk Framingham cohort. RESULTS According to traditional risk factors, a significant difference was observed in systolic blood pressure and total cholesterol (greater in the hypertensive group), and in the prevalence of the male gender, smoking, and diabetes, which were greater in the CRF group. The latter had a greater degree of left ventricular hypertrophy, lower diastolic blood pressure, and a lower prevalence of familial history of cardiovascular disease and obesity. Patients with CRF had a greater relative risk compared with the Framingham control population, but it did not differ from that observed in the group of hypertensive individuals. CONCLUSION The prevalence of cardiovascular disease and traditional risk factors is high among renal transplantation candidates. The Framingham equations do not adequately quantify the real cardiovascular risk; other risk factors specific for that population probably contribute to their greater cardiovascular risk.

Abstract
OBJECTIVES The aims of this study were to evaluate iodoform base materials for root canal treatment of necrotic primary teeth, and to compare them with traditionally used zinc oxide and eugenol (ZOE). SAMPLE AND METHODS Zinc oxide and eugenol and Vitapex (a premixed calcium hydroxide and iodoform paste) were compared for root canal treatment in 52 necrotic primary teeth in two groups of children with a mean age of 5 years and 8.4 months. All the patients were followed-up clinically and radiographically 3 months and 10-16 months postoperatively. RESULTS The overall success rates of Vitapex and ZOE were 100% and 78.5%, respectively. Using Fisher's Exact Test, the difference was statistically significant (P < 0.05). CONCLUSION Both ZOE and Vitapex gave encouraging results. Vitapex, however, can be used more safely whenever there is a doubt about the patient's return for follow-up.

Abstract
We report a large spin-polarized current injection from a ferromagnetic metal into a nonferromagnetic semiconductor, at a temperature of 100 Kelvin. The modification of the spin-injection process by a nanoscale step edge was observed. On flat gallium arsenide [GaAs(110)] terraces, the injection efficiency was 92%, whereas in a 10-nanometer-wide region around a [111]-oriented step the injection efficiency is reduced by a factor of 6. Alternatively, the spin-relaxation lifetime was reduced by a factor of 12. This reduction is associated with the metallic nature of the step edge. This study advances the realization of using both the charge and spin of the electron in future semiconductor devices.

Abstract
A semiautomated turbidimetric technic for determination of the concentration of fibrinogen in plasma was compared with chemical analysis of the fibrin formed by addition of thrombin to plasma. The overall coefficient of correlation between the two methods was 0.98, although the turbidimetric technic was somewhat more accurate in hypofibrinogenemic plasma, and the chemical method, in normal plasma.
