The Effectiveness of Rehabilitation Based on an Original Computer Program: Case Study of a Patient With Kinaesthetic Aphasia

The Effectiveness of Rehabilitation Based on an Original Computer Program: Case Study of a Patient With Kinaesthetic Aphasia

Background: This article is about the rehabilitation of a patient with kinaesthetic aphasia based on an original computer program. The program facilitates the practice of correct kinaesthetic responses in patients with impaired sensation of the configuration of the various elements of the articulation apparatus.

Case description: The study was conducted on JB, a male patient with kinaesthetic aphasia following left hemisphere apoplexy. The computer-assisted therapy began in February 2006 and lasted until the end of June 2006. The article provides a detailed account of the changes in the patient's functioning resulting from the speech therapy conducted in the year 2006, and presents the results of the speech examination conducted after 33 months since its completion. The second study was performed in order to evaluate the lasting effect of the therapy.

Conclusions: The results of this study have demonstrated the effectiveness of speech therapy using an original computer program for the rehabilitation of patients with kinaesthetic aphasia.

The role of neuronal apoptosis inhibitory protein (NAIP) in acute myeloid leukemia patients

Abstract

Acute myeloid leukemia (AML) is a heterogeneous, highly malignant neoplasm. Apoptosis is a complex process executed by caspases and suppressed by the inhibitor of apoptosis (IAP) family. Neuronal apoptosis inhibitory protein (NAIP), IAP’s member, may play an exceptional role in the mechanisms of tumors’ resistance to chemotherapy. The aims of the study were to assess the expression of NAIP in leukemic blasts of AML patients using flow cytometry and to evaluate its influence on disease outcome. NAIP expression was found in 106 out of 108 patients. A higher complete response rate was associated with a low expression of NAIP, age < 60 yo, and white blood cell count < 20 G/L (p = 0.009, p = 0.033, and p = 0.076, respectively) in univariate analyses and a low NAIP expression and age < 60 yo (p = 0.025 and p = 0.013, respectively) in multivariate analyses. Longer overall survival (OS) in the univariate analysis was influenced by a low NAIP expression, age < 60 yo, and intensive chemotherapy (p = 0.033, p < 0.001, and p < 0.001, respectively). In the intensively treated group, better OS was observed in patients with age < 60 yo, de novo AML, and a low NAIP expression (p = 0.03, p = 0.024, and p = 0.07, respectively). In multivariate analysis, longer OS was associated with age < 60 yo (p = 0.009) and de novo AML (p = 0.007). In conclusion, we suggest that NAIP might play an adverse role in response to chemotherapy.

Zearalenone Contamination of the Aquatic Environment as a Result of its Presence in Crops / Pojava Mikotoksina U Vodenom Okolišu Zbog Njihove Prisutnosti U Usjevima

Abstract

The aim of this study was to establish a relation between zearalenone contamination of crops in the Polish province of Wielkopolska and its occurrence in aquatic ecosystems close by the crop fields. Water samples were collected from water bodies such as drainage ditches, wells, or watercourses located in four agricultural areas. Moreover, control water samples were collected from the Bogdanka river, which was located outside the agricultural areas and near an urban area. Cereal samples were collected in the harvest season from each agricultural area close to tested water bodies. Zearalenone (ZEA) was found in all water and cereal samples. The highest concentrations were recorded in the postharvest season (September to October) and the lowest in the winter and spring. Mean ZEA concentrations in water ranged between 1.0 ng L-1 and 80.6 ng L-1, and in cereals from 3.72 ng g-1 to 28.97 ng g-1. Our results confirm that mycotoxins are transported to aquatic systems by rain water through soil.

The expression BIRC6 gene in patients with chronic lymphocytic leukemia – a preliminary study

ABSTRACT

The BIRC6 gene encodes the Bruce (Apollon) protein. This belongs to the III class of Inhibitors of the Apoptosis Protein (IAP) and demonstrates anti-apoptotic activity (binding, inhibiting and degrading the caspases). Moreover, the Bruce protein shows multilevel activities and additional functions. The Bruce protein is involved in the maintenance of cell viability, and it is also suggested that it plays an important role in cell proliferation and diversification. Many researchers have noticed elevated BIRC6 gene expression in cell lines of brain cancer and ovarian carcinoma, leukemia, breast cancer and even in colorectal cancer tissues. Resistance to chemotherapy-inducted apoptosis in cancers characterized by BIRC6 gene over-expression was also reported. The aim of the study was to assess the BIRC6 gene expression in peripheral blood lymphocytes of patients diagnosed with chronic lymphocytic leukemia.
