Investigation of the effects of peppermint (Mentha piperita) on the biochemical and anthropometric profile of university students

The hypolipidemic effects of several medicinal plants have already been demonstrated, but many plants commonly used to treat diseases still need to be studied. Peppermint (Mentha piperita) is widely consumed by the population for different purposes, but not for the treatment of dyslipidemias. The objective of this study was to examine the effects of this plant on human biochemical and anthropometric profiles and blood pressure, based on the administration of peppermint juice twice daily for 30 days. Blood samples were collected before and after the treatment in order to determine the glycemic and lipid profiles, and the Body Mass Index (BMI) analysis was performed. Results indicated that 41.5% of the subjects showed a reduction in glycemia, 66.9% in total cholesterol levels, 58.5% in triacylglycerides, 52.3% in LDL-c (low-density lipoproteins) indices, 70% in GOT (glutamic-oxaloacetic transaminase) levels, 74.5% in GPT (glutamic-pyruvic transaminase) levels, and that 52% presented an increase in HDL-c (high-density lipoprotein cholesterol) indices. Also, 52.5% showed a decrease in blood pressure and 48.7% in BMI. The use of peppermint by humans can be considered beneficial in the prevention and treatment of risk factors of chronic degenerative diseases.

Physical-chemical, caloric and sensory characterization of light jambolan (Syzygium cumini Lamarck) jelly

In Brazil, several little economically explored fruits have good potential as raw material for the agro-industry. This study aimed to produce and determine the physical-chemical and sensory characteristics of light jambolan jelly. This fruit has intense purple color, which gave the jellies - both standard and light - a quite attractive visual aspect. The light jellies exhibited similar physical-chemical characteristics to the ones developed through the conventional method and; with the proportion of sweeteners used, the caloric values of the formulations were reduced to the range of 41 to 53%, attending the requirements of the Brazilian legislation for this type of product. The sensory profile obtained for the 4 light formulations developed, clearly showed the tasters' preference for the jelly elaborated with the association of cyclamate and saccharin. Thus, the results revealed good perspectives for the application of this fruit in the food industry.

Arterite de Takayasu com estenose de artéria renal diagnosticada em paciente com 65 anos de idade

Resumo Arterite de Takayasu é uma doença rara, de etiologia desconhecida, que acomete a aorta e seus principais ramos. É uma patologia, geograficamente mais comum no Sudeste Asiático, que acomete principalmente mulheres em idade reprodutiva. A apresentação clínica é inespecífica, com sinais e sintomas que variam de acordo com o seguimento arterial acometido. O vaso mais comumente afetado é a artéria subclávia, enquanto a estenose de artéria renal é relativamente incomum. Comprometimento cardíaco e associação com outras patologias também podem estar presentes. Apresentamos neste relato o caso de uma paciente idosa com diagnóstico tardio de arterite de Takayasu e várias comorbidades ou complicações relacionadas.

Sensibility of the PCR technique in the detection of Stenocarpella sp. associated with maize seeds

Maize seeds, infected by Stenocarpella species, are important sources of inoculum for the introduction and dissemination of stalk and ear rot and macrospore leaf spot diseases. The use of healthy seeds is an important strategy for the preventive control of these diseases. However, one of the difficulties in the health quality control programs for maize seeds is the availability of a reliable and quick method for detecting these fungi during routine seed analyses. Therefore, the objective of the present study was to investigate the possibility of using the PCR technique as an alternative method for accurately detecting these pathogens in maize seed samples. Maize seeds were kept in contact with S. maydis colonie developed in PDA media containing mannitol at -1.4 MPa for 72 h. The seed samples used in this study were prepared with infected seeds at incidences of 100, 20, 10, 2, 1 and zero %.The primers used were able to detect S. maydis fungi in association with seeds with a maximum of 2% , however those primers were not able to differentiate between the two species.
