title: TRANSILIAC ENDOSCOPIC ASSISTED ILIF: A CADAVERIC STUDY

description: ABSTRACT Objective: Demonstrate the feasibility of endoscopic assisted L5S1 intraforaminal lumbar interbody fusion (iLIF) through a transiliac approach. Methods: Ten transiliac iLIF and ten supra iliac iLIF were performed bilaterally at L5S1 in five randomly selected fresh-frozen human cadavers. The following measurements were recorded: distances from the transiliac track to the iliac crest, posterior superior iliac spine, and superior gluteal neurovascular bundle; pelvic parameters; approach angles; cage’s lateral and AP center point ratio (CPR); percentage of the cage crossing the midline in the AP and lateral views. Endplate integrity was assessed through endoscopic visualization. In addition, the facet joint, sacroiliac joint, iliolumbar ligament, and exiting and traversing nerve roots were checked for integrity through anatomic dissection. Results: In the transiliac technique, the axial and coronal approach angles were significantly decreased by 13.5º (95% CI -15.5; -11.5; p value&lt;0.001) and 13.2º (95% CI -15.3; -11.1; p value&lt;0.001), respectively, the sagittal approach angle was significantly increased by 5.4º (95% CI 1.8,8.9; p-value = 0.008), and the AP CPR was significantly higher (MD 0.16; 95% CI 0.12,0.20; p value&lt;0.001). The percentage of the cage crossing the AP view’s midline was increased by 31.6% (95% CI 19.8,43.4; p value&lt;0.001). The integrity of endplates, facet joints, sacroiliac joints, iliolumbar ligament, and exiting and traversing nerve roots was maintained. Conclusion: L5S1 transiliac iLIF is a feasible surgical technique. It allows a more centrally placed interbody cage in the coronal plane without compromising the anterior position in the lateral plane. The integrity of the major anatomic structures at risk was preserved. Evidence Level III: A case-control study.

title: Chemical Composition and Functional Properties of Dietary Fiber Concentrates Obtained from Peach Palm By-Product

description: The aim of this study was to produce and to characterize dietary fiber concentrates (DFCs) obtained from the peach palm by-product (PPB). Subcritical water extraction (SWE) and aqueous extractions at low pressure in magnetic (LPMS) and orbital (LPOS) stirring were carried out to DFCs production. DFCs and the untreated PPB were analyzed for composition, functional properties, scanning electron microscopy and infrared spectroscopy. The aqueous extraction treatments increased the total dietary fiber content, due to the removal of sugars (88.7-99.6%) and the partial leaching of proteins and ashes. The DFC obtained by SWE had the highest content of soluble and insoluble dietary fiber. The methods of aqueous extraction changed the structure of fiber components, that becomes more porous and fragmented, improving the functional properties, as water and oil absorption. Cellulose was the most abundant component of the samples and the alteration in its conformation was observed in the infrared spectra. The principal component analysis showed that the changes on the composition and functional properties were associated with the treatments applied. DFCs produced in this work, specially by SWE, are considered interesting alternatives to promote the utilization of peach palm by-product as a fiber-rich component.

title: KINESIOTAPING IN DISCOPATHIES AND DEGENERATIVE SPINAL DISEASES: SYSTEMATIC REVIEW

description: ABSTRACT Neuromuscular taping or kinesiotaping is a technique widely used in spinal disorders. However, the scientific evidence of its use in discopathies and degenerative spine pathology is unknown. This study aimed to analyze the published clinical trials on neuromuscular taping in subjects with discopathies and degenerative spinal injuries. For this purpose, a literature search was performed following PRISMA guidelines in the following databases: PubMed, Web of Science (WOS), Scopus, Medline, and Cinahl. In analyzing bias and methodological quality, we used: the PEDro scale, Van Tulder criteria, and risk of bias analysis of the Cochrane Collaboration. A total of 5 articles were included that obtained a mean score of 6.2 on the PEDro scale. There is moderate evidence that, in the short term, neuromuscular taping reduces analgesic consumption and improves the range of motion and muscle strength in the posterior musculature. In addition, there is limited evidence that it can improve quality, while the scientific evidence on the effect of neuromuscular taping on pain is contradictory. The application of neuromuscular taping on discopathies and degenerative processes of the spine should be cautiously undertaken until more conclusive results are obtained, and the long-term effects are assessed. Level of evidence I; Systematic review.

title: Characterization of raw and thermochemically-treated mesocarp fibers of Oenocarpus bataua, an Amazon palm

description: ABSTRACT Background: Patauá (Oenocarpus bataua Mart.) is a palm tree belonging to the botanical family Arecaceae that occurs throughout the Amazon. Like açaí, an edible pulp is extracted from its fruits, remaining a fiber-rich waste. Revealing the potential of such raw or thermochemically modified fibers for producing bioproducts is a novelty in the literature. Therefore, this work aimed to characterize patauá fibers in natural and alkali-treated conditions to support future bioproduct applications. Alkaline treatments were performed under mechanical stirring combining two NaOH levels (5 and 10%) and two temperatures (80 and 100°C). Morphological characterization was performed by light microscopy and scanning electron microscopy (SEM). The contents of the structural and non-structural chemical components were determined, and chemical groups were evaluated by Fourier-transform infrared spectroscopy (FTIR). The physical characterization included moisture content, apparent density, and water absorption tests. Results: The macerate revealed short fibers with typical elongated morphology, mean cell wall thickness (4.10 µm) greater than the mean lumen width (3.01 µm), and mean length of 445 µm. The alkaline treatments partially individualized the fibers from bundles, cleaned extractives from the surface, and unblocked superficial pits by removing silica-rich structures. They substantially removed non-cellulosic components, but FTIR showed condensed lignin exposed on the fiber surface. Density and water uptake increased concerning natural fibers. Patauá’s short length and susceptibility to modification through thermochemical treatments that concentrated cellulose up to 50% indicated great potential for developing composites and nanofibers. Regardless of the NaOH content, 100°C was more efficient in concentrating cellulose. Conclusion: Patauá fibers have unique natural characteristics. They occur as flatted fiber bundles, have silicon-rich structures obstructing their superficial pits, and comprise more lignin than cellulose.

title: Insecticide resistance levels and associated mechanisms in three Aedes aegypti populations from Venezuela

description: BACKGROUND The massive use of insecticides in public health has exerted selective pressure resulting in the development of resistance in Aedes aegypti to different insecticides in Venezuela. Between 2010 and 2020, the only insecticides available for vector control were the organophosphates (Ops) fenitrothion and temephos which were focally applied. OBJECTIVES To determine the state of insecticide resistance and to identify the possible biochemical and molecular mechanisms involved in three populations of Ae. aegypti from Venezuela. METHODS CDC bottle bioassays were conducted on Ae. aegypti collected between October 2019 and February 2020 in two hyperendemic localities for dengue in Aragua State and in a malaria endemic area in Bolívar State. Insecticide resistance mechanisms were studied using biochemical assays and polymerase chain reaction (PCR) to detect kdr mutations. FINDINGS Bioassays showed contrasting results among populations; Las Brisas was resistant to malathion, permethrin and deltamethrin, Urbanización 19 de Abril was resistant to permethrin and Nacupay to malathion. All populations showed significantly higher activity of mixed function oxidases and glutathione-S-transferases (GSTs) in comparison with the susceptible strain. The kdr mutations V410L, F1534C, and V1016I were detected in all populations, with F1534C at higher frequencies. MAIN CONCLUSION Insecticide resistance persists in three Ae. aegypti populations from Venezuela even in the relative absence of insecticide application.

title: Nectarine Coated with Biopolymeric Nanocapsules Containing Eugenol to Control Brown Rot

description: Infections in fruits caused by fungi reduce the quantity and quality of food for human consumption, in addition to causing economic losses. In this sense, this study aimed to address the effects of eugenol nanocapsules (NCs) based on chitosan and carboxymethylcellulose in protecting nectarines against Monilinia fructicola, a brown rot agent, a worldwide important disease. NCs were prepared by layer-by-layer (LbL) self-assembly starting from an anionic template and deposition with up to two polymeric layers. The hydrodynamic diameters ranged from 158 nm (nanoemulsion), 360 nm (one polymeric layer) to 398 nm (two polymeric layers). NCs presented, during the in vitro release, the release of eugenol following a first order process. In addition to being in the region of stability (zeta potential ca. |30| mV), the capsules showed good adhesion to the nectarine surface. In relation to brown rot, the eugenol NCs with chitosan proved to be the best formulation compared to nanoemulsion and NCs with two polymeric layers for its control, increasing the probability that the fruits remain without symptoms, even after 7 days. Therefore, this study demonstrated that chitosan NCs containing eugenol could be an alternative to preserve fruit for longer periods in post-harvest.

title: Differences in the Chemical Composition of Melon (Cucumis melo L.) Nectar Explain Flower Gender Preference by Its Pollinator, Apis mellifera

description: Melon is a pollinator-dependent crop that relies mainly on bees to set fruits. However, man-selected varieties vary in their attractiveness to flower visitors, and some flower genders and melon types may be less visited than others, harming pollination. We investigated the nectar composition of male, female and hermaphrodite flowers of 270 individuals of five commercial melons Cucumis melo (Cantaloupe, Charentais, Galia, Piel de Sapo, and Yellow), and its role in flower visit by Apis mellifera foragers. We found that melon nectar is composed mainly of sugars and amino acids such as tyrosine, phenylalanine, tryptophan, and flavonoids kaempferol-3-O-neohesperidoside, luteolin hexoside, and kaempferol rhamnoside. But the amount of these chemical compounds varies among the flower genders. We also developed an accurate regression model to predict the number of bee visits to melon flowers based on the nectar composition. Our results indicate that nectar composition plays little role in bee discrimination among flowers of different melon types but is essential to the honeybee choice between flower gender. The amounts of phenylalanine (49.40%) and tryptophan (12.05%) in the nectar are related to bee preference for hermaphrodite flowers. More visits to hermaphrodite flowers contribute to setting and developing well-formed fruits, increasing productivity.

title: Predictive Potential of Motivation to Learn in the use of Learning Strategies

description: Abstract This paper investigates motivation to learn and learning strategies in a sample of 353 Brazilian students in elementary and secondary education. Data were collected through the Motivation to learn scale and two Learning Strategies Assessment Scales, one for elementary school and another for high school. Learning goals and use of metacognitive strategies were predominant in the sample. Significant positive and negative correlations between the subscales were found. Two models emerged explaining 33% and 37% of the variance in the use of learning strategies that can be attributed to motivation to learn factors. The study underscores the importance of motivation to learn for engaging students in strategic behavior.
