Use of Nile tilapia (Oreocromis niloticus) processing residues in the production of pâtés with the addition of oregano (Origanum vulgare) essential oil.

The effect of the use of Nilo tilapia filleting residues in the production of pâtés with the addition of oregano essential oil stored for 90 days at 4 °C was evaluated. For that, 5 treatments were performed as follows: TSA-control treatment; TES with the addition of sodium erythorbate; and formulation TOE1 with 600 ppm oregano essential oil; TOE2 with 1000 ppm essential oil; and TOE3 with 1400 ppm essential oil. The pâtés showed adequate technological and physicochemical characteristics and microbiological counts within the legislation standards. No significant differences were observed in the luminosity of the pâté formulations during storage, and the addition of oil contributed to the increase in a* values and stability of b* values. Regarding the lipid and protein oxidation, TOE3 showed lower values at the end of the shelf-life. The addition of essential oil did not affect the hardness and cohesiveness of the products. The fatty acids in greater amounts in the samples were linoleic, oleic, palmitic, and stearic acids. The analysis of biogenic amines indicated that only the treatments with the highest amounts of sodium erythorbate (TES and TOE1) showed losses of spermidine. It was observed that decreasing the inclusion of sodium erythorbate and increasing the inclusion of oregano essential oil resulted in a drop in cadaverine values. A total of 46 volatile compounds were detected in the samples with the highest amount of free fatty acids and all the formulations were well accepted sensorially.

Combining Unimanual and Bimanual Therapies for Children with Hemiparesis: Is There an Optimal Delivery Schedule?

Constraint-induced movement therapy (CIMT) and bimanual therapy (BT) are among the most effective hand therapies for children with unilateral cerebral palsy (uCP). Since they train different aspects of hand use, they likely have synergistic effects. The aim of this study was to examine the efficacy of different combinations of mCIMT and BT in an intensive occupational therapy program for children with uCP. Children (n = 35) participated in intensive modified CIMT (mCIMT) and BT, 6 weeks, 5 days/week, 6 h/day. During the first 2 weeks, children wore a mitt over the less-affected hand and engaged in functional and play activities with the affected hand. Starting in week 3, bimanual play and functional activities were added progressively, 1 hour/week. This intervention was compared to two different schedules of block interventions: (1) 3 weeks of mCIMT followed by 3 weeks of BT, and (2) 3 weeks of BT followed by 3 weeks of mCIMT. Hand function was tested before, after, and two months after therapy with the Assisting Hand Assessment (AHA), Pediatric Evaluation of Disability Inventory (PEDI), and Canadian Occupational Performance Measure (COPM). All three groups of children improved in functional independence (PEDI; p < 0.031), goal performance (COPM Performance; p < 0.0001) and satisfaction (COPM Satisfaction; p < 0.0001), which persisted two months post-intervention. All groups showed similar amounts of improvement, indicating that the delivery schedule for mCIMT and BT does not significantly impact the outcomes.

Effects of a 12-week, seated, virtual, home-based tele-exercise programme compared with a prerecorded video-based exercise programme in people with chronic neurological impairments: protocol for a randomised controlled trial.

INTRODUCTION: Exercise is vital to staying well and preventing secondary complications in people with chronic neurological impairments (CNI). Appropriate exercise is often inaccessible to this population. The purpose of the study is to investigate the effects of a seated, virtual exercise programme on heart rate, recovery, fatigue, pain, motivation, enjoyment and quality of life in people with CNI. METHODS AND ANALYSIS: Individuals with CNI will be screened for eligibility, and 60 participants will be randomised 1:1 into either a live or prerecorded group. There is no geographical limitation to where participants reside, since participation is virtual. The study will be coordinated by one site in White Plains, New York, USA. The live group will exercise with an instructor via Zoom while the prerecorded group will exercise at their chosen time using prerecorded videos, 3×/week for 12 weeks. PRIMARY OUTCOME MEASURES: change in heart rate during exercise/recovery. SECONDARY OUTCOME MEASURES: fatigue, motivation, level of pain and exertion, physical well-being, enjoyment of physical activity, motivation and quality of life. Outcomes will be assessed at baseline, midpoint, end of study and 1-month poststudy. Adverse events, medication changes and physical activity will be tracked throughout. Within-group and between-group comparisons will be performed by using analysis of covariance and regression. ETHICS AND DISSEMINATION: BRANY IRB approval: 22 September 2020, protocol #20-08-388-512. All participants will provide written informed consent. Results will be disseminated through presentations, publications and ClinicalTrials.gov. TRIAL REGISTRATION NUMBER: NCT04564495.

Effect of the addition of the probiotic Bifidobacterium animalis subsp. Lactis (BB-12) in free and microencapsulated form and the prebiotic inulin to synbiotic dry coppa.

The effect of the addition of the prebiotic inulin and free and microencapsulated Bifidobacterium animalis subsp. Lactis (BB-12) strains to synbiotic dry coppa formulations was evaluated during 45 days of ripening. The following formulations were made: control C without probiotic and prebiotic; PROB with free probiotic; SYNB with free probiotic and inulin; ENPROB with microencapsulated probiotic, and ENSYNB with microencapsulated probiotic and inulin. The incorporation of BB-12 with inulin provided adequate physicochemical characteristics (proximate composition, weight loss, pH, water activity (aw), and instrumental color). The treatments PRO and SYNB showed lower lipid and protein oxidation levels. The treatments PROB, SYNB, ENPROB, and ENSYNB had viable cell counts above 109 CFU/g and can be considered probiotic. In the in vitro gastrointestinal simulation, the BB-12 strain showed survival and growth capacity in saline solution and at low pH values for all treatments. The sample SYNB was the most accepted by the assessors in the sensory evaluation. Therefore, dry coppa can be used as a vehicle for the development of a synbiotic fermented meat product.

Improvements in Upper Extremity Function Following Intensive Training Are Independent of Corticospinal Tract Organization in Children With Unilateral Spastic Cerebral Palsy: A Clinical Randomized Trial.

Background/Objectives: Intensive training of the more affected upper extremity (UE) has been shown to be effective for children with unilateral spastic cerebral palsy (USCP). Two types of UE training have been particularly successful: Constraint-Induced Movement Therapy (CIMT) and Bimanual training. Reorganization of the corticospinal tract (CST) early during development often occurs in USCP. Prior studies have suggested that children with an ipsilateral CST controlling the affected UE may improve less following CIMT than children with a contralateral CST. We tested the hypothesis that improvements in UE function after intensive training depend on CST laterality. Study Participants and Setting: Eighty-two children with USCP, age 5 years 10 months to 17 years, University laboratory setting. Materials/Methods: Single-pulse transcranial magnetic stimulation (TMS) was used to determine each child's CST connectivity pattern. Children were stratified by age, sex, baseline hand function and CST connectivity pattern, and randomized to receive either CIMT or Bimanual training, each of which were provided in a day-camp setting (90 h). Hand function was tested before, immediately and 6 months after the intervention with the Jebsen-Taylor Test of Hand Function, the Assisting Hand Assessment, the Box and Block Test, and ABILHAND-Kids. The Canadian Occupational Performance Measure was used to track goal achievement and the Pediatric Evaluation of Disability Inventory was used to assess functioning in daily living activities at home. Results: In contrast to our hypothesis, participants had statistically similar improvements for both CIMT and Bimanual training for all measures independent of their CST connectivity pattern (contralateral, ipsilateral, or bilateral) (p < 0.05 in all cases). Conclusions/Significance: The efficacy of CIMT and Bimanual training is independent of CST connectivity pattern. Children with an ipsilateral CST, previously thought to be maladaptive, have the capacity to improve as well as children with a contralateral or bilateral CST following intensive CIMT or Bimanual training.

Effects of chronic stretching on soleus muscle of Wistar female rats / Efectos del estiramiento crónico en el músculo sóleo de ratas hembras Wistar

The purpose of this study was to evaluate the chronic effects of stretching exercise on soleus muscle histomorphology and histomorphometry of young and aged rats. Thirty-eight female rats were divided into young control group (YCG, n=10;274±50 g); young stretching group (YSG, n=8;274±12 g); aged control group (ACG, n=10;335±39 g); and aged stretching group (ASG, n=10;321±32g). A mechanical apparatus was used to stretch muscle in 4 repetitions, 60 s each, 30 s interval between repetitions in each session, 3 times a week for 3 weeks. Twenty-four hours after the last stretching session, soleus muscle was removed for micromorphology and immunostaining analysis. Data analyses were performed with one-way ANOVA, post-hoc Tukey, or Kruskal-Wallis tests for parametric and nonparametric, respectively (p≤0.05). Muscle fiber cross-sectional area (MFCSA) of ACG was lower (18 %) compared to the YCG. Stretching increased MFCSA comparing YSG to YCG (5,681.15± 1,943.61 µm2 vs 5,119.84±1,857.73 µm2, p=0.00), but decreased comparing ASG to ACG (3,919.54± 1,694.65 µm2 vs 4,172.82±1,446.08 µm2, p=0.00). More serial sarcomere numbers were found in the YSG than YCG (12,062.91±1,564.68 vs 10,070.39±1,072.38, p=0.03). Collagen I and collagen III were higher in YSG than ASG (7.44±7.18 % vs 0.07±0.09 %, p=0.04) and (14.37 %± 9.54 % vs 5.51 %±5.52 %, p=0.00), respectively. TNF-a was greater in ASG than YSG (43.42 %±40.19 % vs 1.72 ± 2.02 %, p=0.00). Epimysium was larger in the YSG compared to YCG (201.83±132.07 % vs 181.09±147.04 %, p=0.00). After 3-week stretching the soleus muscles from aged rats were smaller than their younger counter-parts. Interestingly, while stretching appeared to positively affect young soleus muscle, the opposite was detected in the muscle of the aged rats.

El propósito de este estudio fue evaluar los efectos crónicos del ejercicio de estiramiento sobre la histomorfología e histomorfometría del músculo sóleo de ratas jóvenes y envejecidas. Se dividieron 38 ratas hembras en un grupo control joven (YCG, n = 10; 274 ± 50 g); grupo de estiramiento joven (YSG, n = 8; 274 ± 12 g); grupo control de edad (ACG, n = 10; 335 ± 39 g); y grupo estiramiento envejecido (ASG, n = 10; 321 ± 32 g). Se usó un aparato mecánico para estirar el músculo en 4 repeticiones, 60 s cada una, intervalo de 30 s entre repeticiones en cada sesión, 3 veces por semana, durante 3 semanas. Veinticuatro horas después de la última sesión de estiramiento, se extrajo el músculo sóleo para análisis de micromorfología e inmunotinción. Los análisis de datos se realizaron con pruebas ANOVA de una vía, Tukey post-hoc o Kruskal-Wallis para pruebas paramétricas y no paramétricas, respectivamente (p≤0,05). El área de la sección transversal de fibra muscular (MFCSA) de GCE fue menor (18 %) en comparación con el GCJ. El estiramiento aumentó ASTFM comparando GEJ con GCJ (5.681,15 ± 1.943,61 µm2 vs 5.119,84 ± 1.857,73 µm2, p = 0,00), pero disminuyó comparando GEE con GCE (3.919,54 ± 1.694,65 µm2 vs 4.172,82 ± 1.446,08 µm2, p = 0,00). Se encontraron más sarcómeros en serie en el GEJ que en el GCJ (12.062,91 ± 1.564,68 vs 10.070,39 ± 1,072.38, p = 0,03). El colágeno I y el colágeno III fueron más numerosos en GEJ que en GEE (7,44 ± 7.18 % vs 0,07 ± 0,09 %, p = 0,04) y (14,37 % ± 9,54 % vs 5,51 % ± 5,52 %, p = 0,00), respectivamente. TNF-α fue mayor en GEE que GEJ (43,42 % ± 40,19 % vs 1,72 ± 2,02 %, p = 0,00). El epimisio fue mayor en el GEJ en comparación con el GCJ (201,83 ± 132,07 % vs 181,09 ± 147,04 %, p = 0,00). Después de 3 semanas de estiramiento, los músculos sóleo de las ratas envejecidas eran más pequeños que sus contrapartes más jóvenes. Curiosamente, si bien el estiramiento pareció afectar positivamente el músculo sóleo joven, se detectó lo contrario en el músculo de las ratas envejecidas.

Double renal artery in human cadavers: a case report / Artéria renal dupla em cadáveres humanos: relato de caso

Two renal arteries supply the human kidneys: one to the right kidney and another to the left kidney, both branches of the abdominal aortic. Renal artery duplication is an anatomical variation, which is a normal flexibility of the topography and morphology in body structures. Functionally, it does not impair the body, as the blood supply is vital to tissue survival. In this context, the case study has great importance, once knowing the variations of the renal vessels assist when structuring surgeries and radiological studies in humans. Variations in vascular anatomy are often found in humans. Several authors characterize it: the prevalence of multiple vessels occurs in approximately 20-50% of cases. This is an observational study; we aimed to describe the anatomical variations concerning the duplicity of the renal artery in human cadavers, focusing on possible implications to clinical and surgical procedures. We dissected and analyzed four urinary block systems in adult cadavers, male, with focus on the vascularization. In these, two right kidneys present double renal arteries. Thus, we can infer that this knowledge can be used to improve surgical interventions, such as transplants.

Os rins são supridos por duas artérias renais, uma para o rim direito e outra para o rim esquerdo, ramos da aorta abdominal. A duplicidade de artéria renal é uma variação anatômica definida como uma flexibilidade normal na topografia e morfologia das estruturas do corpo, que em termos funcionais não há prejuízo do órgão, uma vez que a irrigação arterial do mesmo é um fator vital para a sobrevivência dos tecidos. Neste contexto, o estudo de caso tem grande importância, sendo que o conhecimento das variações dos vasos renais auxilia na estruturação da anatomia cirúrgica e em estudos radiológicos e clínicos para humanos. Às variações na anatomia vascular são frequentemente encontradas, no homem, é caracterizada por vários autores, com uma prevalência de vasos múltiplos que ocorre em cerca de 20-50% dos casos. Este trabalho trata-se de um estudo observacional, cujo objetivo é descrever variações anatômicas de duplicidade da artéria renal em cadáveres humanos, com enfoque nas possibilidades de implicação clínico-cirúrgica desta variação anatômica. Foram dissecados e analisados 04 blocos de sistema urinário em cadáveres adultos, do sexo masculino, com enfoque na vascularização. Observou-se que destes blocos, dois rins direitos apresentavam artérias renais duplas. Sendo assim, podemos inferir que o conhecimento das variações anatômicas em humanos pode servir como subsídio para aprimoramento de intervenções cirúrgicas como em transplantes e cirurgias renais.
