Cerebral Gliomas Patterns at the General Hospital of Douala, Cameroon  [PDF]
Aurélien Ndoumbe, Mathieu Motah, Bea Jesse Ikango, Mireille Moumi, Amadou Fewou, Albert Mouelle Sone
Open Journal of Modern Neurosurgery (OJMN) , 2018, DOI: 10.4236/ojmn.2018.84035
Abstract: The diagnosis and management of cerebral gliomas are challenging. The goal of this study was to evaluate the pattern of cerebral gliomas at the General Hospital Douala, Cameroon. A retrospective study was carried out over a period of 10 years. Non-glial lesions were not included. Data were analyzed with Epi info version 7.2.2.6 (Microsoft, Seattle, USA). 220 cases of brain tumors, comprising 56 gliomas (25.46% of all brain tumors) were managed during the study period. The mean age of the patients was 42.93 ± 16.90 years. 35 cases (62.5%) were males. Patients over 15 years of age represented 91.07% (n = 51) of the cases. The most frequent presenting complaints were headache and vomiting with 52 cases (92.86%) and 47 cases (83.93%) respectively. Brain computed tomography was done for all patients. The most frequent histological type was astrocytoma with 22 cases (39.29%) followed by glioblastoma with 20 cases (35.71%). The most performed surgical technique was partial removal with 33 cases (58.93%), followed by open biopsy with 14 cases (25.00%). Radiotherapy was administered to 54 patients (96.43%). The outcome ranged from full recovery in 8 cases (14.29%), recovery with persisting symptoms, in 15 cases (26.79%) and death in 26 cases (46.43%). Seven patients (12.50%) were lost to view. In this series, cerebral gliomas affected most often adult males. Most of them presented with signs of raised intracranial pressure. The outcome was poor with 46.43% of patients dying before 2 years after diagnosis.
Homological description of crystal structures on Lusztig's quiver varieties
Bea Schumann
Mathematics , 2015,
Abstract: Using methods of homological algebra, we obtain an explicit crystal isomorphism between two realizations of crystal bases of the lower part of the quantized enveloping algebra of (almost all) finite dimensional simply-laced Lie algebras. The first realization we consider is a geometric construction in terms of irreducible components of certain quiver varieties established by Kashiwara and Saito. The second is a realization in terms of isomorphism classes of quiver representations obtained by Reineke using Ringel's Hall algebra approach to quantum groups. We show that these two constructions are closely related by studying sufficiently generic representations of the preprojective algebra.

Rock art which is not so Levantine. The ritual survival of painted rock shelters: the example of la Vacada (Castellote, Teruel)
Martínez Bea, Manuel
Trabajos de Prehistoria , 2004,
Abstract: In this paper we present four figures of the shelter of La Vacada, the stylistic characteristics and graphic conventions of which allow us to classify them as non- Levantine Rock Art. We suggest the possibility that these figures could belong to a proto-historic date with clear hellenistic-roman influence, emphasising the indigenous cultural and geographic context, which was as much celtiberian as Iberian.. We also analyse several decorated pottery fragments from Numancia and some iberian sites as parallels for the figures studied. En este artículo presentamos cuatro figuras dentro del conjunto del abrigo de La Vacada cuyas características estilísticas y convenciones gráficas permite descartar su pertenencia al arte levantino. Sugerimos la posibilidad de que estas representaciones pudieran adscribirse a época protohistórica ya avanzada con evidentes influencias helenístico- romanas, enfatizando el contexto geográfico y cultural indígena, tanto celtibérico como ibérico, al que se asocian. Se analizan algunos fragmentos cerámicos decorados numantinos e ibéricos como paralelos de las figuras estudiadas.

Abstract: trypanosomosis is the most economically important disease constraint to livestock productivity in sub-saharan africa and has significant negative impact in other parts of the world. livestock are an integral component of farming systems and thus contribute significantly to food and economic security in developing countries. current methods of control for trypanosomosis are inadequate to prevent the enormous socioeconomic losses resulting from this disease. a vaccine has been viewed as the most desirable control option. however, the complexity of the parasite's antigenic repertoire made development of a vaccine based on the variable surface glycoprotein coat unlikely. as a result, research is now focused on identifying invariant trypanosome components as potential targets for interrupting infection or infection-mediated disease. immunosuppression appears to be a nearly universal feature of infection with african trypanosomes and thus may represent an essential element of the host-parasite relationship, possibly by reducing the host's ability to mount a protective immune response. antibody, t cell and macrophage/monocyte responses of infected cattle are depressed in both trypanosusceptible and trypanotolerant breeds of cattle. this review describes the specific t cell and monocyte/macrophage functions that are altered in trypanosome-infected cattle and compares these disorders with those that have been described in the murine model of trypanosomosis. the identification of parasite factors that induce immunosuppression and the mechanisms that mediate depressed immune responses might suggest novel disease intervention strategies.
Immune Response of Cattle Infected with African Trypanosomes

Abstract: Trypanosomosis is the most economically important disease constraint to livestock productivity in sub-Saharan Africa and has significant negative impact in other parts of the world. Livestock are an integral component of farming systems and thus contribute significantly to food and economic security in developing countries. Current methods of control for trypanosomosis are inadequate to prevent the enormous socioeconomic losses resulting from this disease. A vaccine has been viewed as the most desirable control option. However, the complexity of the parasite's antigenic repertoire made development of a vaccine based on the variable surface glycoprotein coat unlikely. As a result, research is now focused on identifying invariant trypanosome components as potential targets for interrupting infection or infection-mediated disease. Immunosuppression appears to be a nearly universal feature of infection with African trypanosomes and thus may represent an essential element of the host-parasite relationship, possibly by reducing the host's ability to mount a protective immune response. Antibody, T cell and macrophage/monocyte responses of infected cattle are depressed in both trypanosusceptible and trypanotolerant breeds of cattle. This review describes the specific T cell and monocyte/macrophage functions that are altered in trypanosome-infected cattle and compares these disorders with those that have been described in the murine model of trypanosomosis. The identification of parasite factors that induce immunosuppression and the mechanisms that mediate depressed immune responses might suggest novel disease intervention strategies.
Patient stress and satisfaction when allowed the presence of an accompanying person during endoscopy  [PDF]
Jesse Lachter, Benjamin Ephraim Bluen
Open Journal of Gastroenterology (OJGas) , 2013, DOI: 10.4236/ojgas.2013.31012
Abstract:

Introduction: Patients undergoing esophagogastroduodenoscopy (EGD) have variable stress and anxiety and therefore commonly receive medications as sedative-anxiolytics. These medications have small but significant risks. To possibly make procedures safer and to increase patient satisfaction, this study aimed to measure the effects of allowing an accompanying person (AP) to be present in the endoscopy suite during EGD. Patients and Methods: Forty-two patients were randomly divided into two groups who would either be or not be offered to have an AP during endoscopy. Spielberger’s well-validated state and trait anxiety evaluations were administered to patients before and after EGD. APs also completed questionnaires as to their reactions after EGD. Results: 84.2% of the patients after EGD recommended accompaniment. Patients who underwent EGD with an AP tended (p < 0.06) to have decreased measurable anxiety compared to patients who were not offered an AP. The benefit was significant for persons with higher levels of anxiety prior to EGD (p < 0.04). Patients undergoing EGD for the first time had significantly more anxiety than those with previous EGD experience (p < 0.034). There was no significant reduction in sedative dosage when APs were present. Conclusions: Offering to permit the presence of an accompanying person during EGD was often shown to improve patient satisfaction and reduce anxiety.

New information concerning anesthesia and surgery for the morbidly obese patient
Jesse Hall
Critical Care , 2005, DOI: 10.1186/cc3932
Abstract: The Editor-in-chief, Adrian Alvarez, trained as an anesthesiologist and general surgeon, and has assembled an international group of distinguished contributors to illuminate the management of the morbidly obese patient. The first three chapters in a section termed 'General aspects' nicely describe the scope of the problem, emphasize the need for a multidisciplinary approach to care, outline the risks and complications related to obesity, and comment on the modifications to informed consent for these patients. Appendices that include examples of patient fact sheets and consent forms are valuable templates for programs developing in this area. This section alone would be a valuable monograph to the reader quite apart from the rest of the text.The remainder of the text is well organized, beginning with five chapters discussing relevant pathophysiology and then discussing preoperative management of the patient and specific management of the common co-morbidities of these patients – including diabetes mellitus, venous thrombo-embolism, and cardiac disease. There are also helpful sections concerning pharmacology and monitoring. One-third of the chapters are directed towards intraoperative management and postoperative care, and include extremely useful information concerning positioning, airway management, care in the intensive care unit, and details of anesthetic management, including a chapter dealing with the obese parturient.Some redundancy exists between chapters – it is common for authors to insert discussions of pathophysiology to explain certain management approaches rather than refer back to chapters on these topics; however, this seems a useful redundancy that clarifies the subject matter at hand. The chapters are well referenced and many of the chapters are rich in tables, figures, and algorithms that provide ready access to the information being discussed.In summary, this is a fine first edition addressing this important aspect of perioperative management.

Heterogeneity in the seed globulin and albumin fractions from African yam bean Sphenostylis stenocarpa (Hoechst. Ex A. Rich) harms
Jesse Machuka
African Crop Science Journal , 2001,
Abstract: Successful fractionation of albumin, globulin and vicilin fractions from dry seeds of African yam bean (Sphenostylis stenocarpa) was achieved using established procedures for preparation of legume seed proteins. The resulting polypeptides were separated by native polyacrylamide gel electrophoresis under both reducing (in the presence of 2-mercaptoethanol [2-ME]) and non-reducing (without 2-ME) conditions. Based on this analysis, it was possible to establish similarities and differences among 26 different accessions of African yam beans collected from local markets in eastern Nigeria. RéSUMé Un fractionnement réussi de l'albumine, du globuline et de la viciline des graines sèches de haricot igname d'Afrique (Sphenostylis stenocarpa) a été réalisé par des procédures établies pour la préparation des protéines des graines des légumineuses. Les polypeptides qui en résultent ont été séparés par un gel d'électrophorèse de polyacrylamide natif sous les conditions de réduction (en présence du 2-mercaptoethanol [2-ME] et de no-réduction (sans 2-ME). Sur base de cette analyse, il a été possible d'établir des similarités et des differences entre les 26 accessions des haricots igname d'Afrique collectées dans les differents marchés lacaux de l'Est du Nigeria.
