The patients with PPS begin to present new limitations on the performance of their ADLs and, at the same time, tend to ignore them, continuing their daily work with greater physical effort. The need for a functional evaluation is therefore necessary to find out where the commitments are in the ADLs and to help them without aggravating the degenerative PPS. To identify the main functional assessment scales used in individuals with PPS. A study review of the literature was performed on the functional scales used in patients with PPS described in the articles in the database. We found 12 functional scales in activities of daily living, as follows: Nottingham Health Profile (NHP), International Classification of Impairments, Disability's and Handicaps (ICIDH), Functional Status Questionnaire (FSQ), Physical Activity Scale for the Elderly (PASE), Sunnas ADL Index, Katz Index, Falls Efficacy Scale (FES), ADLs-Staircase, Barthel Index, Functional Independence Measure (FIM), Older Adult Resource Survey (OARS), and Self-Reporter ADL. None of the 12 scales mentioned in our study is validated for the use in patients with PPS, the most scales found in the literatures reviewed in this research were NHP and ICIDH. Therefore, we found 9 scales validated in Brazil, Barthel Index, Functional Independence Measure (FIM), Functional Status Questionnaire (FSQ), Falls Efficacy Scale (FES), Nottingham Health Profile (NHP), International Classification of Impairments, Disability's and Handicaps (ICIDH), Older Adult Resource Survey (OARS), Katz Index and Self-Reporter ADL.\u0000","PeriodicalId":9319,"journal":{"name":"Brazilian Journal of Biological Sciences","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76064934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neocarya macrophylla (Sabine) Prance ex F. White (Malpighiales: Chrysobalanaceae) have been reportedly used in traditional medicine to treat snake envenomation. Bioassay-guided isolation of antivenom principles was carried out on the leaf of N. macrophylla against Naja nigricollis venom. The methanol extract of N. macrophylla leaf and its ethylacetate and n-butanol fraction significantly (P < 0.05) protected mice against venom-induced lethality with 100% survival rate and there was remarkable inhibition of the poisonous effects of PLA2 enzyme by the extracts and the fractions. Encouraged by this result, the ethylacetate soluble fraction was subjected to purification using vacuum liquid chromatography and gel filtration which led to the isolation of quercetin as the bioactive principle. The identity of the compound was determined on the basis of chemical tests, and by comparison of its 1H-NMR data with literature, this is the first report of isolation of this compound from the leaf of the plant. However, the results of the study suggests that the leaf of N. macrophylla possess significant antisnake venom activity which provide the scientific basis for its use in traditional treatment of snakebites.\u0000","PeriodicalId":9319,"journal":{"name":"Brazilian Journal of Biological Sciences","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73311770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adult males in active, inactive and revival phases of spermatogenesis were injected with serotonin and dopamine in multiple doses and their dissected testes were submitted to histomorphological examinations. Though serotonin treatment during active phase showed increased values for testicular index, acinar diameter and proportion of mature spermatozoa, only the testicular index values differed statistically from that of controls. Serotonin administration during inactive phase caused an increase in testicular index and acinar diameter, reduction in intra and interacinar spaces and pycnosis of germ cells and detection of division stages. A notable increase in the testicular index, acinar diameter and fresh batches of spermatozoa was perceptible in crabs injected with serotonin during revival phase. In contrast, dopamine injection showed a decline in testicular activity irrespective of the phase of spermatogenesis, as evinced from low testicular index, acinar diameter, presence of small, irregularly shaped acini with indistinct acinar boundaries, reduction in the number of mature spermatozoa and absence of division stages. To conclude, the stimulatory neurotransmittant, serotonin can be used to induce testicular maturation in species of aquaculture potential.\u0000","PeriodicalId":9319,"journal":{"name":"Brazilian Journal of Biological Sciences","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89095186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As arbuscular mycorrhizae (AM) was associated with early invasion of land plants on earth, AM may have some role in defining the first seral community in any land. Two riverbanks were selected to study their pioneer plant community structure with species composition and diversity, soil characters and arbuscular mycorrhizal association; and correlations among these factors. Species composition, diversity and richness indices, active AM association of early colonizing plant species, soil texture, moisture, pH and E.C in two river banks differed. Similarity index for plant species between the two communities was poor. Diversity and richness indices were high in K site while evenness was high in R site. AM colonization and spore density correlated highly with plant cover and frequency in both riverbanks. Soil moisture showed a strong negative impact on mycorrhization, soil organic carbon showed little. Soil pH showed varied correlation in different sites. Early colonizing plants in R site with silt-loam soil with high moisture level are found poorly mycotrophic or nonmycotrophic; though plant cover correlated highly with mycotrophy in both sites. Plants in sandy soil of K site are highly mycotrophic and with high arbuscular and vesicular colonizations. The distribution of frequency in R site is highly deviated from Raunkiuer’s frequency class; in K site it is rather stable. The soil condition is only key factor to determine plant composition and plant-mycorrhizal relations influencing colonization of early seral community.\u0000","PeriodicalId":9319,"journal":{"name":"Brazilian Journal of Biological Sciences","volume":"161 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87990671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
