title: ENTREPRENEURSHIP IN FAMILY BUSINESSES: CURRENT RESEARCH AND FUTURE CHALLENGES

description: ABSTRACT Purpose: The purpose of this paper is to review the literature on entrepreneurship in family businesses. Originality/gap/relevance/implications: Despite the fact that other literature reviews show the existence of papers that explore entrepreneurship in the context of family-owned businesses, there are no systematic reviews about the idiosyncrasies of the relation between these fields. Key methodological aspects: We reviewed the scientific production published in journals relevant to the family businesses field. Seventy-three articles published about entrepreneurship in family businesses were categorized through the scope literature review technique, according to variables such as journal of publication, research topic addressed, and methodological procedures adopted. Summary of key results: The integrated reading of articles categorized in this review allowed us to identify the exploration of different research topics and methodological approaches in the attempts to comprehend entrepreneurial phenomena in family businesses. Key considerations/conclusions: We conclude that the potential of this approach will be achieved by the construction of a theoretical framework able to contribute to the understanding of intrinsic aspects of family-owned businesses. This approach, by involving phenomena that are complementary in the light of the interaction between family and business, may contribute for the generation of further knowledge about this type of organization, and for the opening of new research avenues on entrepreneurship and family businesses.

title: Pitfalls of diffusion-weighted imaging of the female pelvis

description: Abstract Diffusion-weighted imaging (DWI) is widely used in protocols for magnetic resonance imaging (MRI) of the female pelvis. It provides functional and structural information about biological tissues, without the use of ionizing radiation or intravenous administration of contrast medium. High signal intensity on DWI with simultaneous low signal intensity on apparent diffusion coefficient maps is usually associated with malignancy. However, that pattern can also be seen in many benign lesions, a fact that should be recognized by radiologists. Correlating DWI findings with those of conventional (T1- and T2-weighted) MRI sequences and those of contrast-enhanced MRI sequences is mandatory in order to avoid potential pitfalls. The aim of this review article is the description of the most relevant physiological and benign pathological conditions of the female pelvis that can show restricted diffusion on DWI.

title: Comparison between conventional protective mechanical ventilation and high-frequency oscillatory ventilation associated with the prone position

description: ABSTRACT Objective: To compare the effects of high-frequency oscillatory ventilation and conventional protective mechanical ventilation associated with the prone position on oxygenation, histology and pulmonary oxidative damage in an experimental model of acute lung injury. Methods: Forty-five rabbits with tracheostomy and vascular access were underwent mechanical ventilation. Acute lung injury was induced by tracheal infusion of warm saline. Three experimental groups were formed: healthy animals + conventional protective mechanical ventilation, supine position (Control Group; n = 15); animals with acute lung injury + conventional protective mechanical ventilation, prone position (CMVG; n = 15); and animals with acute lung injury + high-frequency oscillatory ventilation, prone position (HFOG; n = 15). Ten minutes after the beginning of the specific ventilation of each group, arterial gasometry was collected, with this timepoint being called time zero, after which the animal was placed in prone position and remained in this position for 4 hours. Oxidative stress was evaluated by the total antioxidant performance assay. Pulmonary tissue injury was determined by histopathological score. The level of significance was 5%. Results: Both groups with acute lung injury showed worsening of oxygenation after induction of injury compared with the Control Group. After 4 hours, there was a significant improvement in oxygenation in the HFOG group compared with CMVG. Analysis of total antioxidant performance in plasma showed greater protection in HFOG. HFOG had a lower histopathological lesion score in lung tissue than CMVG. Conclusion: High-frequency oscillatory ventilation, associated with prone position, improves oxygenation and attenuates oxidative damage and histopathological lung injury compared with conventional protective mechanical ventilation.

title: Is the herb-shrub composition of veredas (Brazilian palm swamps) distinguishable?

description: ABSTRACT Vereda (Brazilian palm swamp) is a poorly known savannic phytophysiognomy that occurs on moist soils with high herb-shrub floristic richness. This study aimed to document the herb-shrub species of veredas of the Estação Ecológica Serra Geral do Tocantins - EESGTO, and compare this flora with other veredas in Brazil. Furthermore, we assessed the similarity of the herb-shrub ﬂora of the studied veredas with that of inventories of other savannas and grasslands in order to evaluate whether veredas possess an exclusive flora. Ordination analysis was performed to understand the floristic relationship among these areas. We recorded 213 species, 105 genera and 49 families at EESGTO, including five new floral records for the Cerrado and 78 for the state of Tocantins. The floristic similarity among veredas at EESGTO and the other sites was low. For all sites, a total of 1,324 species were recorded, of which 342 were unique to veredas and 187 unique to moist grasslands (campos limpos úmidos). After reviewing databases, 14.3 % of these species remained exclusive to veredas and moist grasslands. The ordination analysis indicated a gradient in floristic composition from wet to dry phytophysiognomies. In conclusion, we recognize a flora that distinguishes veredas from other Cerrado phytophysiognomies.

title: Osteogenic differentiation of adipose tissue-derived mesenchymal stem cells cultured with different concentrations of prolactin

description: ABSTRACT The objective was to evaluate the in vitro effect of prolactin in osteogenic potential of adipose tissue-derived mesenchymal stem cells (ADSCs) in female rats. ADSCs were cultured in osteogenic medium with and without the addition of prolactin and distributed into three groups: 1) ADSCs (control), 2) ADSCs with addition of 100ng/mL of prolactin and 3) ADSCs with addition of 300ng/mL of prolactin. At 21 days of differentiation, the tests of MTT conversion into formazan crystals, percentage of mineralized nodules and cells per field and quantification of genic transcript for alkaline phosphatase, osteopontin, osteocalcin, bone sialoprotein, BMP-2 and collagen I by real-time RT-PCR were made. The addition of prolactin reduced the conversion of MTT in group 3 and increased the percentage of cells per field in the groups 2 and 3, however without significantly increasing the percentage of mineralized nodules and the expression of alkaline phosphatase, osteopontin, osteocalcin, bone sialoprotein, BMP-2 and collagen I. In conclusion, the addition of prolactin in concentrations of 100ng/mL and 300ng/mL does not change the osteogenic differentiation to the ADSCs of female rats despite increase in the cellularity of the culture.

title: Assessment of Length of Maternal Cervix between 18 and 24 weeks of Gestation in a Low-Risk Brazilian Population

description: Abstract Purpose To determine cervical biometry in pregnant women between 18 and 24 weeks of gestation and the ideal mode of measurement of cervical length in cases of curved and straight cervical morphology. Methods The uterine cervices of 752 low-risk pregnant women were assessed using transvaginal ultrasound in a prospective cross-sectional study. In women with straight uterine cervices, cervical biometry was performed in a continuous manner. In women with curved uterine cervices, the biometry was performed using both the continuous and segmented techniques (in segments joining the cervical os). Polynomial regression models were created to assess the correlation between the cervical length and gestational age. The paired Student t-test was used to comparemeasuring techniques. Results The cervical biometry results did not vary significantly with the gestational age and were best represented by linear regression (R2 = 0.0075 with the continuous technique, and R2 = 0.0017 with the segmented technique). Up to the 21st week of gestation, there was a predominance of curved uterine cervix morphology (58.9%), whereas the straight morphology predominated after this gestational age (54.2%). There was a significant difference between the continuous and the segmented measuring methods in all the assessed gestational ages (p &lt; 0.001). Conclusion Cervical biometry in pregnant women between 18 and 24 weeks was represented by a linear regression, independently of the measuring mode. The ideal measuring technique was the transvaginal ultrasound performed at a gestational age 21 weeks.

title: Morpho-agronomic characterization of sweet potato germplasm

description: ABSTRACT Sweet potato (Ipomoea batatas) spreads mainly by vegetative propagation, and therefore this vegetable may have duplicate accessions in germplasm banks. The authors aimed to characterize morpho-agronomically the sweet potato germplasm from the Active Germplasm Bank (AGB) of Universidade Federal de Sergipe (UFS).The experiment was carried out at the Research Farm “Campus Rural da UFS”. The experimental design was a randomized block design, testing 73 sweet potato accessions with two replicates and four plants per plot. Morpho-agronomic traits of aboveground part and roots were evaluated. We observed that the leaf lobe type, the number of lobes per leaf, shape of central lobe, and general leaf shape were traits which provided the most variability among the accessions. For damage caused by soil insects, 52 accessions showed tolerance. The accessions presented a range from 0.33 to 2.71 t/ha for dry mass of aboveground part and from 1.20 to 10.89 t/ha for the total productivity of the roots. The high phenotypic variability of this crop shows good prospect for breeding programs.

title: Traumatic rupture of liver hydatid cysts into the peritoneal cavity of an 11-year-old boy: a case report from Iran

description: Abstract This is the first published case report of an 11-year-old patient with a rupture of a liver hydatid cyst (HC) into the peritoneal cavity after an abdominal trauma in Iran. The disease was diagnosed using focused abdominal sonography for trauma. To date, no cases of traumatic ruptures of liver HCs in children have been reported in Iran. In the endemic regions of the world, where patients suffer from a history of trauma and constant abdominal symptoms or anaphylactic shock, early diagnosis of HC is crucial as it may disseminate to other organs. The condition needs conservative surgery and follow-up.
