Overview of essential tremor

Neuropsychiatric Disease and Treatment , 2010,
Abstract: Theresa A Zesiewicz, Abinaya Chari, Israt Jahan, Amber M Miller, Kelly L SullivanDepartment of Neurology, Parkinson Research Foundation, James A. Haley Veterans Administration Hospital,University of South Florida, Tampa, FL, USAAbstract: Essential tremor (ET) is one of the most common movement disorders in the world. Despite this, only one medication (propranolol) is approved by the Food and Drug Administration (FDA) to treat it. Fortunately, recent studies have identified some additional medications as treatment of ET. Surgical procedures, such as deep brain stimulation of the ventral intermediate nucleus of the thalamus, offer treatment for refractory tremor. The epidemiology, pathogenesis, and medical and surgical treatment of ET will be discussed in this paper.Keywords: Essential tremor, diagnosis, treatment, pathogenesis
Non-Linear Mathematical Model of the Interaction between Tumor and Oncolytic Viruses  [PDF]
Seetharaman Usha, Vairamani Abinaya, Shunmugham Loghambal, Lakshmanan Rajendran
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.39160
Abstract: A mathematical modeling of tumor therapy with oncolytic viruses is discussed. The model consists of two coupled, deterministic differential equations allowing for cell reproduction and death, and cell infection. The model is one of the conceptual mathematical models of tumor growth that treat a tumor as a dynamic society of interacting cells. In this paper, we obtain an approximate analytical expression of uninfected and infected cell population by solving the non-linear equations using Homotopy analysis method (HAM). Furthermore, the results are compared with the numerical simulation of the problem using Matlab program. The obtained results are valid for the whole solution domain.
Ethical challenges facing Zimbabwean media in the context of the Internet
Tendai Chari
Global Media Journal : African Edition , 2011, DOI: 10.5789/3-1-19
Abstract: The Internet has fundamentally transformed the practice of journalism in Africa. It has spawned enormous opportunities and challenges for the African media, and Zimbabwe is no exception. Not only has the concept of news changed but also the manner in which it is gathered and disseminated. Journalists no longer feel compelled to adhere to the ethical cannons of their profession owing to certain qualities of the Internet. This paper investigates ethical challenges faced by the Zimbabwean media as a result of the Internet. In particular the paper discusses ethical challenges in the Zimbabwean media that are either directly or indirectly linked to the Internet. The main argument advanced in this paper is that while the Internet has brought about a number of opportunities for the Zimbabwean media, the same technology has been the root of unethical reporting.
Bilateral dorsal perilunate dislocation of wrist
Chari P
Indian Journal of Orthopaedics , 2010,
Abstract: We present a case of simultaneous dorsal perilunate dislocation of both wrists, without a history of fall on outstretched hands. In contrast, it appeared that the mechanism was reverse. His hands were held in radial deviation with wrists in full palmar flexion. The forearms were in neutral position and elbows in mid-flexion. The wrists were suddenly and forcibly pronated. The radiographs of both wrists showed dorsal perilunate dislocation with avulsion fracture of the tip of ulnar styloid process and avulsion fracture of posterior horn of lunate. Radial translation of the carpal bones was also noted. The mechanism is proposed and discussed.

Hydatid disease of scapula and upper third of humerus treated by en bloc excision and fibular bone grafting
Chari P
Indian Journal of Orthopaedics , 2007,
Abstract: 35-year-old male patient presented with gradually increasing painful swelling of the right shoulder, which was incised and drained and wound persisted as a discharging sinus on the anterolateral aspect of the deltoid region with seropurulent discharge. A clinical diagnosis of tuberculosis of the shoulder was made. Plain skiagram of the right shoulder revealed multicystic lesion involving the entire scapula and upper third of the humerus with loss of joint space and pathological fracture at the junction of upper one-third and lower two-thirds of the humerus. A clinico-radiological diagnosis of hydatid disease was made. In view of the extensive involvement of the scapula with stiff shoulder and an active sinus, a two-stage surgical procedure was performed. Stage 1 consisted of en bloc excision of the scapula, upper half of the humerus and lateral end of the clavicle. Stage II surgery, consisting of fibular bone grafting. Tablet albendazole (400 mg, thrice daily) was given as systemic scolicidal agent. This case is reported in view of it′s rarity and to highlight the management.
Fresh fractures of the scaphoid : A rationale method of treatment
Chari P
Indian Journal of Orthopaedics , 2006,
Abstract: Background : Scaphoid, among all carpal bones, is very vulnerable for fracture due to its unique shape and situation with greater articular surface. All scaphoid fractures are being treated with below elbow POP thumb spica casts keeping hand in ball throwing position. A few scaphoid fractures through the waist take longer time to unite, if not end in nonunion. These fractures were found to be displaced unimpacted trans-scaphoid fractures through the waist. Method : The effect of various positions of hand, wrist and forearm over unimpacted displaced scaphoid fractures through the waist were studied on dissected hand specimens and in patients with skiagrams. It was observed that possible radial deviation of hand over neutrally held wrist and forearm would result in anatomical reduction with impaction between the fragments. Added compression effect at site of fracture, necessary for early fracture healing, is produced by passively abducting the first metacarpal bone. Results : Of 68 scaphoid fractures under study, 24 and 41 were displaced and undisplaced ones through the waist respectively. All of them united in eight to ten weeks time as any fracture, when immobilised undisturbed with anatomic reduction and added compression between the fragments except one displaced fracture which took eight more weeks of immobilization for union and revascularilization of proximal fragment. Conclusion : This study showed that all scaphoid fractures in particular those through waist when rigidly immobilized unite as any fracture in eight to ten weeks provided the proximal fragment maintains proper blood supply. Otherwise it would further eight week of immobilization for the proximal fragment to get revascularize following union.

Minimal Affinizations of Representations of Quantum Groups: the rank 2 case

Physics , 1994,
Abstract: We define the notion of a minimal affinization of an irreducible representation of $U_q(g)$. We prove that minimal affinizations exist and establish their uniqueness in the rank 2 case.
Representations of Affine and Toroidal Lie Algebras
Vyjayanthi Chari
Mathematics , 2010,
Abstract: We discuss the category $\cal I$ of level zero integrable representations of loop algebras and their generalizations. The category is not semisimple and so one is interested in its homological properties. We begin by looking at some approaches which are used in the study of other well--known non--semisimple categories in the representation theory of Lie algebras. This is done with a view to seeing if and how far these approaches can be made to work for $\cal I$. In the later sections we focus first on understanding the irreducible level zero modules and later on certain universal modules, the local and global Weyl modules which in many ways play a role similar to the Verma modules in the BGG--category $\cal O$. In the last section, we discuss the connections with the representation theory of finite--dimensional associative algebras and on some recent work with J. Greenstein.
