Minimally processed fruit salad enriched with Lactobacillus acidophilus: Viability of anti-browning compounds in the preservation of color

Minimal processing promotes browning of some vegetal tissues due to cell membrane disruption, which results in the release of oxidative enzymes. This study evaluated the efficiency of citric acid, ascorbic acid, sodium metabisulfite and L-cysteine hydrochloride to retard enzymatic browning of minimally processed fruit salad and enriched this product with Lactobacillus acidophilus LA-5. Control treatment was fruit salad immersed in water. Polyphenol oxidase (PPO) and color (L*, a*, b*, index color - CI, browning index - BI, c*, and h°) were analyzed. The viability of L. acidophilus was also evaluated using Rogosa agar in fruit salads containing anti-browning compounds in higher concentrations. PPO presented a significant difference among control and fruit salad treated with ascorbic acid and L-cysteine hydrochloride, indicating the highest anti-browning activity of these compounds. The fruit color was affected by processing and storage time, with a reduction in the values of L* over time. Values of a*, c*, h° angle and CI indicated a predominance of red color in the fruit salad. Salads containing anti-browning compounds in higher concentrations presented viability of L. acidophilus above 7.43 log CFU/g up to the fifth day of storage, indicating that the product can be promised as probiotic. Thus, the fruit salad treated with anti-browning compounds has potential use as a probiotic carrier.Keywords: Fresh-cut fruits, color, ascorbic acid, vegetable matrix, probiotic culture

Influence of normal mammary epithelium on breast cancer progression: the protective role of early pregnancy

AIMS AND BACKGROUND: The microenvironment has a well recognized role in breast cancer progression. Despite different theories, the mechanism of early pregnancy protection in mammary carcinogenesis is unknown. Since pregnancy is responsible for mammary gland differentiation, we tested the hypothesis that differentiated mammary epithelial cells may inhibit breast cancer progression. In other words, the protective role of early pregnancy could be due to the inhibitory influences of the more differentiated mammary tissue. METHODS: In order to test our hypothesis, we used 30 female Balb/c nude mice and MCF-7 cells of breast adenocarcinoma. The female mice were divided into two test groups, group I (GI) and group II (GII), and a control group. In GII, the animals were submitted to epithelial removal in the left fourth inguinal mammary gland at 3 weeks of age. Both groups were given continuous hormonal treatment to simulate the pregnancy development of the mammary gland. Two million MCF-7 cells were then injected into the fourth inguinal mammary gland (GI) or in the respective cleared mammary fat pad (GII). Five weeks later the mice were sacrificed and their tumors removed. Tumor development rates and tumor volumes were determined and proliferation and apoptosis were evaluated by immunohistochemistry. RESULTS: Tumors of GII mice had a larger mean volume than those of GI mice (P = 0.001, Mann-Whitney U-test) and an apparent increase in proliferation, demonstrated by a higher staining intensity for proliferating cell nuclear antigen (PCNA). As tumors presented caspase 8 staining, there may be apoptotic activation involved in cell death, mainly through an extrinsic pathway. CONCLUSIONS: These results suggest that a differentiated intact mammary gland may have an inhibitory influence on mammary tumor growth in mice

Single Fetal Death in Twin Pregnancy. What Will Be the Problems to the Surviving Co-Sib?

Na gravidez bigemelar, a morte de um dos fetos no segundo e terceiro trimestre é uma complicação rara, variando a taxa de incidência entre 2,6 e 6,8%. Este acontecimento determina um aumento das taxas de morbilidade e mortalidade perinatal para o gémeo sobrevivente, especialmente em gravidezes monocoriónicas, quando a morte fetal é devida à síndroma de tranfusão feto-fetal. Para alguns autores o atraso de crescimento intrauterino e a prematuridade são os principais factores de risco para o aumento da morbilidade e mortalidade do gémeo sobrevivente. A patofisiologia de instalação dos distúrbios cerebrais no gémeo sobrevivente após a morte do feto irmão não está definida, nem o intervalo de tempo que medeia entre a morte e o estabelecimento das lesões. Também não existe um protocolo definitivo de seguimento destas gravidezes e, posteriormente, do gémeo sobrevivente. No período de 1 de Setembro de 1994 a 31 de Dezembro de 1998, foram seguidas, na consulta de Gravidez Múltipla da Maternidade Dr. Alfredo da Costa, 235 gravidezes bigemelares. Em nove casos (3,8%) ocorreu morte de um dos fetos com idade gestacional acima das 13 semanas. Em cinco das nove gravidezes foi conhecida a causa de morte, quatro das quais foram atribuídas à síndroma de tranfusão feto-fetal. A taxa de prematuridade do gémeo sobrevivente foi de 44,4% (4/9) e a de mortalidade de 11,1%(1/9). A taxa de morbilidade neonatal foi de 62,5% (5/8), na maioria dos casos por complicações inerentes à prematuridade. A taxa de morbilidade neurológica foi de 37,5% (3/8). A taxa de lesões neurológicas major foi de 25% (2/8) e ocorreu em recém-nascidos de termo. A síndroma de transfusão feto-fetal, como causa de morte fetal, associou-se aos casos com pior prognóstico no que se referiu ao gémeo sobrevivente.O crescimento do gémeo sobrevivente parece depender das lesões provocadas pela morte do feto irmão. Os autores finalizam com uma proposta de atitudes obstétricas e pediátricas em relação ao gémeo sobrevivente

Gastrointestinal Tuberculosis Mimicking Crohn’s Disease

We present the case of a 24-year-old woman with complaints of abdominal pain, bloody diarrhea, and weight loss for 3 months. An outpatient colonoscopy revealed scattered ulcers, suggestive of Crohn's disease (CD). Histopathology also favored the diagnosis of CD. However, after admission to our hospital for further investigation, a chest radiograph revealed pulmonary cavitations. A computed tomography scan suggested the diagnosis of active pulmonary tuberculosis (TB). Therefore, a bronchofibroscopy, a total colonoscopy with ileoscopy, and an upper endoscopy were performed. Not only were acid-fast bacilli present in both bronchoalveolar lavage fluid and gastric juice, but also in colonic biopsies. A complete resolution of gastrointestinal symptoms was achieved 2 weeks after starting anti-TB drugs.info:eu-repo/semantics/publishedVersio

Allergic conjunctivitis and conjunctival provocation tests in atopic dogs.

INTRODUCTION: Canine atopic dermatitis (cAD) is a very common disease, but little is known about eye involvement. The conjunctival provocation test (CPT) is used in human to study the ocular response to allergenic stimuli and to evaluate anti-allergic therapy. To our knowledge it has not been used in dogs. OBJECTIVES: To evaluate the prevalence of ocular signs in a population of atopic dogs and relate these with clinical cAD scores; and the usefulness of CPT for dust mites in atopic dogs with itchy eyes. PROCEDURES: Sixty cAD patients were evaluated for (i) ocular signs of allergic conjunctivitis including conjunctival hyperemia, chemosis, epiphora, ocular discharge, pruritus and corneal involvement, graded 0 to 3 according to severity, and (2) cAD Extent and Severity Index (CADESI-03). Additionally, CPTs for Dermatophagoides farinae (n = 12) and Dermatophagoides pteronyssinus (n = 12) were performed in sensitized atopic dogs and 24 control dogs. RESULTS: Periocular and ocular signs of allergy were present in 60% (36/60) of cases. Conjunctival hyperemia (90%) was the most common sign. Severity of ocular signs was significantly correlated with eye pruritus (r(s)  = 0.690, P = <0.001) and skin lesions score for head region (r(s) = 0.261, P = 0.04). A highly significant difference (P < 0.001, Fisher test) was found in CPTs between the test and the control groups. CONCLUSION:  Allergic conjunctivitis signs associated with cAD seem under valuated so these patients would benefit from an ophthalmologic evaluation. Furthermore, we found CPT to be a reliable, easy to perform and safe test for the etiologic diagnosis of allergic conjunctivitis in the dog

Experience and Learning from the COVID-19 Pandemic in Portugal: Perceptions of Community Pharmacy Professionals

Background: During the COVID-19 pandemic, community pharmacy (CP) professionals were among those who experienced the greatest risk of contracting SARS-CoV-2, which forced major adaptations. Objectives: The objectives of the study were to describe the changes implemented in CP professionals during the pandemic, understand the perception of professionals about their experience, and explore changes to remain. Methods: An observational and cross-sectional study was conducted via an online questionnaire (June-September 2020). The target population was CP professionals working in Portugal for >2 years and serving the public during the pandemic. Results: Of a total of 353 participants, 84% were female (mean age of 37.6 years), and 81% were pharmacists (mean professional experience of 12.9 years). In the management and organizational dimensions, the most mentioned changes were adaptation to legislative changes (90%), fluctuations in the treasury (82%), and reduction of working hours (46%). Only 2% resorted to simplified layoff. In the back office, there was a need to adapt stock management (93%) and purchase personal protective equipment (99%). In the front office, there was a change in service policies - wicket or conditional opening (92%), routes of the arrival of user requests (91%), and home delivery (82%). Physical changes occurred in 100% of pharmacies. The most frequently implemented procedures were the use of protection systems and PPE, articulation with hospital pharmacies for dispensing in proximity (75%), and training in this area (55%). Regarding interpersonal climate, improvements in the connection between team members are evident: increase in mutual help (57%), solidarity (54%), and group cohesion (50%); in the relationship with clients, the majority indicated the replacement of the usual user by third parties (71%), and changes in communication channels (increase in use of technological means 68%). Conclusions: Results illustrate the profound impact of the pandemic on CP professionals, both professionally and personally. It also highlights the importance of their roles in proximity and community support. © 2023 S. Karger AG.

Faster and slower posttraining recovery in futsal: Multifactorial classification of recovery profiles

© 2019 Human Kinetics, Inc. Purpose: To investigate the existence of faster vs slower recovery profiles in futsal and factors distinguishing them. Methods: 22 male futsal players were evaluated in countermovement jump, 10-m sprint, creatine kinase, total quality of recovery (TQR), and Brunel Mood Scale (fatigue and vigor) before and immediately and 3, 24, and 48 h posttraining. Hierarchical cluster analysis allocated players to different recovery profiles using the area under the curve (AUC) of the percentage differences from baseline. One-way ANOVA compared the time course of each variable and players’ characteristics between clusters. Results: Three clusters were identified and labeled faster recovery (FR), slower physiological recovery (SLphy), and slower perceptual recovery (SLperc). FR presented better AUC in 10-m sprint than SLphy (P = .001) and SLperc (P = .008), as well as better TQR SLphy (P = .018) and SLperc (P = .026). SLperc showed better AUC in countermovement jump than SLphy (P = .014) but presented worse fatigue AUC than SLphy (P = .014) and FR (P = .008). AUC of creatine kinase was worse in SLphy than in FR (P = .001) and SLperc (P < .001). The SLphy players were younger than SLperc players (P = .027), whereas FR were slower 10-m sprinters than SLphy players (P = .003) and SLperc (P = .013) and tended to have higher maximal oxygen consumption than SLphy (effect size = 1.13). Conclusion: Different posttraining recovery profiles exist in futsal players, possibly influenced by their physical abilities and age/experience
