A rare case of meningioma
Introduction: A meningioma is a kind of brain tumour that develops in the meninges, a layer that protects the Brain and Spinal cord. It is included in this group even though it is not an actual brain tumour since it has the potential to pressurise the brain, nerves, and arteries around it. Glioma is the most common kind of brain tumour, followed by meningioma.
Clinical observation: Right eye cataract causes headaches and pain in the right eye and a fever (Temperature - 101 f).
Diagnostic evaluation: CT score 8/25 on HRCT Thorax, RDW - 18.2 percent, HCT - 20%, Diagnostic Evolution, 3200 WBC/cu mm total WBC count, 15.9% blood, 5.0 million total RBCs per cubic millimetre, RDW is 18.2%, HCT is 20%, and total WBC count is 3200/cubic millimetre, Monocytes account for 2%, Granulocytes for 20%, and Lymphocytes for 77%, on an MRI brain with contrast, AST (SGOT) is 112U/L. The lateral wall of the cavernous sinus is at the ocular apex, there is a meningioma nerve sheath tumour.
Therapeutic intervention: Some treatments employed include craniotomy, Tablet Dolo 650 mg Once in Day, Capsule Felicita Once in Day, and Tablet Azee 500 mg Once in Day.
Outcomes: The patient's condition improves after treatment. His fever and headache went away, and his vision improved following surgery.
Conclusion: With a headache, vision problems, and a fever, my patient was brought to the Neuro unit. His condition has improved upon obtaining adequate therapy
Neural Network Based Approach For Signature Verification And Recognition
Signature can be seen as an individual characteristic of a person which can be used for his/her validation. An automated signature verification and recognition technique saves valuable time and money. Neural network based approach for signature verification and recognition discussed in this paper which enables the user to recognize whether a signature is original or a fraud. The user introduces into the computer the scanned images, modifies their quality by image enhancement and noise reduction techniques, to be followed by feature extraction and neural network training, and finally verifies the authenticity of the signature. The paper is primarily focused on five features of extraction like eccentricity, kurtosis, skewness, orientation and centroid. The extracted features of investigation signature are compared with the previously trained features of the reference signature. This technique is suitable for various applications such as bank transactions, passports with good authentication results et
Authentication System Using Text Passwords Along With Persuasive Cued Click Points
This paper presents an implementation of a two level authentication using a combination of text passwords and persuasive cued click points on three or five images. The most common method for authentication is textual passwords. Though textual passwords are easy to remember, they are vulnerable to eavesdropping, dictionary attacks, social engineering and shoulder surfing. Graphical passwords have been introduced as an alternative to textual passwords. But same as textual passwords, shoulder surfing attacks make most of the graphical schemes vulnerable. To address this problem, textual passwords can be combined with graphical schemes in what gives a two level security without the use of additional hardware. This paper also presents an evaluation of the text based passwords and graphical password schemes which have been tested previously but failed, including usability and security evaluations
A Drosophila Model of ALS: Human ALS-Associated Mutation in VAP33A Suggests a Dominant Negative Mechanism
ALS8 is caused by a dominant mutation in an evolutionarily conserved protein, VAPB (vesicle-associated membrane protein (VAMP)-associated membrane protein B)/ALS8). We have established a fly model of ALS8 using the corresponding mutation in Drosophila VAPB (dVAP33A) and examined the effects of this mutation on VAP function using genetic and morphological analyses. By simultaneously assessing the effects of VAPwt and VAPP58S on synaptic morphology and structure, we demonstrate that the phenotypes produced by neuronal expression of VAPP58S resemble VAP loss of function mutants and are opposite those of VAP overexpression, suggesting that VAPP58S may function as a dominant negative. This is brought about by aggregation of VAPP58S and recruitment of wild type VAP into these aggregates. Importantly, we also demonstrate that the ALS8 mutation in dVAP33A interferes with BMP signaling pathways at the neuromuscular junction, identifying a new mechanism underlying pathogenesis of ALS8. Furthermore, we show that mutant dVAP33A can serve as a powerful tool to identify genetic modifiers of VAPB. This new fly model of ALS, with its robust pathological phenotypes, should for the first time allow the power of unbiased screens in Drosophila to be applied to study of motor neuron diseases
A 67 Year-Old Man with Fatigue
Case Report
A 67 year-old male with a past medical history of hypertensionand insulin-dependent type II diabetes complicated byneuropathy, retinopathy, and chronic kidney disease presentedto the hospital with a complaint of fatigue. The patient notedgeneralized weakness that had begun the morning of admissionafter two days of malaise and subjective fever. This weaknessprevented him from being able to rise from a sitting position,resulting in a fall off the couch. He denied injury from this fallalong with shortness of breath or chest pain, however, he didadmit to two episodes of vomiting the day prior to admission.
The patient was taking the following medications: furosemide,aspirin, isosorbide mononitrate, lipitor, levothyroxine,candesartan, metoprolol, clopidogrel, doxazosin, calcitrioland Insulin 70/30. Medical history included, hyperlipidemia,hypothyroidism, benign prostatic hypertrophy, stable angina,and peripheral vascular disease along with the conditionslisted above. Past surgical history included 2 stents in the LADcoronary artery, vitrectomy, and transurethral resection of theprostate (TURP). Additionally, the patient noted that he livedalone after having retired from teaching and denied any drugs,smoking or alcohol
A Case Study on Braking of 3 Phase Induction Motor with High Load Using DC Injection
There are number of applications in the real-life scenario where one needs frequent start and stop of the machine running on electric motor. The motors in such machines continues to rotate even after the power supply is cut off due to inertia which is generated because of high load that is coupled to the motor. In order to reduce and stop these motors as per requirement, different braking techniques are used. These braking techniques can be classified as mechanical and electrical braking. In mechanical braking the speed of the motor is purely reduced by using various mechanical braking. Whereas in the electrical braking reverse torque is generated. In comparison with electrical braking, mechanical braking has many disadvantages of increased maintenance, wear and tear of components of system, and also in some application the use of mechanical system is avoided because of the high compactness, hence electrical braking is preferred over mechanical braking. Dynamic braking is one of the electrical methods for stopping a 3 phase induction motor connected to high load within fraction of seconds. Stopping of motor is achieved by connecting it with Dc Injection Unit a type of dynamic braking immediately after it is turned off, and thereby rapidly stopping the motor
