Micritização em Conchas de Biválvios da Formação Morro do Chaves, Bacia de Sergipe - Alagoas

A descoberta de importantes campos de petróleo, (e.g Campos de Marlim e Marlim do Sul na Bacias de Campos, Campo de Lula na Bacia de Santos e Campo de Golfinho na Bacia do Espírito Santo), nas bacias de margem leste brasileiras, gerou um crescente interesse nos estudos sedimentológicos buscando a melhor compreensão das rochas carbonáticas que compõem esses sistemas. Dentre essas rochas estão as coquinas, que são geradas através de acumulações de conchas ou fragmentos de conchas depositadas pela ação de algum agente de transporte. As coquinas afloram na Bacia de Sergipe-Alagoas e compõem a Formação Morro do Chaves, a qual é utilizada como base para estudos de reservatórios petrolíferos análogos aos das Bacias de Campos, Santos e Espírito Santo. O objetivo deste trabalho é estudar o processo de micritização, um dos fatores responsáveis pela alteração do intervalo conchífero da Formação Morro do Chaves, uma vez que são raros ou inexistentes estudos relacionados a esse processo. Para a realização deste trabalho foi utilizado o testemunho de sondagem 2-SMC-1-AL, proveniente da Pedreira Atol, e adicionalmente foram utilizadas 11 lâminas petrográficas. No testemunho foram identificados nove intervalos com bioclastos com envelopes de micrita. A espessura desses envelopes nos intervalos varia de 30 μm a 100 μm e ocorrem em fragmentos de bioclastos e mais frequentemente em bioclastos inteiros, sem nenhuma relação preferencial com a orientação ou concavidade dos bioclastos. Os processos responsáveis pela formação dos envelopes podem ser Micritização Destrutiva ou Construtiva. Apesar da maior parte dos bioclastos estar muito recristalizada, ambos os processos foram identificados nos envelopes de micrita. Os intervalos apresentam predominância em matriz composta por material carbonático, indicando ambiente deposicional de baixa energia (propício para a ocorrência da micritização), no entanto a presença de pequena quantidade de material terrígeno bem selecionado indica descarga fluvial no sistema lacustre levando a entrada de material siliciclástico e ao retrabalhamento das conchas

L’efficacia del Kinesio Taping nel trattamento del linfedema secondario a tumore al seno. Revisione sistematica della letteratura.

Background; il linfedema secondario al tumore al seno è una patologia cronica, progressiva e invalidante che insorge nel 15-20% delle donne trattate per carcinoma mammario, a causa dell’asportazione o del danneggiamento dei linfonodi del cavo ascellare. La terapia standard attuale prevede trattamenti compressivi ad alta invasività, che possono portare ad una scarsa compliance. L’applicazione del Kinesio Tape potrebbe essere una valida alternativa al trattamento compressivo. Obiettivo: l’obiettivo di questa revisione della letteratura è quello di ricercare evidenze riguardo l’efficacia del Kinesio Taping rispetto alla terapia standard, nel trattamento delle donne con linfedema secondario a tumore al seno, negli outcome di diminuzione di volume dell’arto affetto e miglioramento della qualità della vita. Metodi: é stata condotta una ricerca sulle banche dati PubMed, PEDro, CINAHL e Cochrane utilizzando parole chiave quali lymphedema, “breast cancer”, mastectomy e “kinesio taping” associate tra loro tramite operatori booleani. Non sono stati posti limiti temporali e sono stati inclusi articoli in lingua italiana, inglese e spagnola. Risultati: cinque studi sono stati considerati eleggibili per questa revisione della letteratura, tre dei quali riguardanti la prima fase di trattamento intensivo e due la seconda fase di mantenimento, tutti aventi come soggetto donne con linfedema secondario a tumore al seno di II e III stadio. In tutti gli studi il trattamento con KT ha portato a miglioramenti statisticamente rilevanti tra prima e dopo il trattamento. Nella prima fase il trattamento standard si è tuttavia confermato più efficace, mentre nella fase di mantenimento il KT ha dato risultati migliori rispetto al manicotto compressivo. Conclusione: nella prima fase di trattamento intensivo il KT è efficace, ma non più del trattamento standard. Nella seconda fase di trattamento il KT pare essere più efficace del manicotto, ma sono necessari ulteriori studi rigorosi in merito

Tattoo-Associated Skin Reaction: The Importance of an Early Diagnosis and Proper Treatment

Tattoo is going to be a very common practice especially among young people and we are witnessing a gradual increase of numerous potential complications to tattoo placement which are often seen by physicians, but generally unknown to the public. The most common skin reactions to tattoo include a transient acute inflammatory reaction due to trauma of the skin with needles and medical complications such as superficial and deep local infections, systemic infections, allergic contact dermatitis, photodermatitis, granulomatous and lichenoid reactions, and skin diseases localized on tattooed area (eczema, psoriasis, lichen, and morphea). Next to these inflammatory skin reactions we have to consider also the possibility of the development of cutaneous conditions such as pseudolymphomatous reactions and pseudoepitheliomatous hyperplasia. The aim of this study is to underline the importance of an early diagnosis by performing a histological examination especially when we are in front of suspected papulonodular lesions arising from a tattoo, followed by a proper treatment, since cutaneous neoplastic evolution is known to be a rare but possible complication

Promoting well-being in old age : the psychological benefits of two training programs of adapted physical activity

In the last few decades, the relationship between physical conditions and mental health has increasingly attracted the interest of researchers and professionals across disciplines. This relationship is especially relevant in old age, as the challenges posed by aging at various levels represent crucial concerns for policy makers. Due to the remarkable increase in life expectancy across countries, sustainable prevention strategies are needed to help individuals preserve psychophysical well-being in old age. In particular, the regular practice of a moderately intense physical activity is recommended by the World Health Organization to enhance balance, prevent falls, strengthen muscles, and promote psychophysical well-being. Daily physical exercise represents a beneficial and low-cost strategy, easily accessible to the general population and potentially customizable to specific needs through brief training programs. Based on these premises, the present research aimed at longitudinally evaluating mental well-being among 58 Italian people aged 67-85, who were involved in two Adapted Physical Activity (APA) training programs. Inclusion criteria for participation comprised high autonomy levels in daily activities, no cognitive impairment, sedentary habits or only occasional performance of moderate physical activity. Based on physical and functional assessment, 39 participants joined a program of adapted motor activity (PoliFit; Study 1), while 19 participants attended a variant program specifically designed for people with osteoporosis (OsteoFit; Study 2). Well-being dimensions were assessed through the Mental Health Continuum-Short Form, the Emotion Regulation Questionnaire and the Satisfaction with Life Scale. Physical functioning were evaluated before and after the programs through the Short Physical Performance Battery and the Handgrip Dynamometer Jamar Test. Findings highlighted that, besides physical benefits, participants reported significantly more adaptive emotion regulation strategies after both training programs; in addition, participants attending OsteoFit reported significantly higher levels of emotional well-being. Results suggest the potential of moderate physical activity in promoting mental health, emphasizing the additional role of training programs as cost-effective opportunities for elderly people to socialize and improve emotional functioning. Overall, the findings support the view of old age as a stage of competence development and adaptive adjustment, rather than a phase of mere psychophysical decline

Exploring Coagulase-Negative Staphylococci Diversity from Artisanal Llama Sausages: Assessment of Technological and Safety Traits

Llama sausage is still produced following artisanal procedures, with the autochthonous microbiota being mainly responsible for the fermentation process. In this work, the taxonomical identification and technological-safety criteria of coagulase-negative staphylococci (CNS) isolated from two dierent productions of llama sausages (P: pilot and A: artisanal) were investigated. Staphylococcus (S) equorum and S. saprophyticus were the species most frequently found in P production, followed by S. succinis and S. warneri; a wider species variability was observed in A factory being S. equorum, S. capitis, S. xylosus, S. pasteuri, S. epidermidis and S. saprophyticus as the main identified species. The technological characterization of 28 CNS strains showed their ability to hydrolyze gelatin and tributyrin together with a relevant nitrate reductase activity. Phenotypic and genotypic approaches were conducted to investigate the main safety traits. Llama\u2019s CNS strains exhibited weak decarboxylase and hemolytic activity and low biofilm production; additionally, no enterotoxin genes were detected. Correlation analysis between phenotypic and genotypic data showed low values for the biofilm parameters, while high correlation was observed for oxacillin, ampicillin, tetracycline and aminoglycosides resistance and their genetic determinants. Data obtained may contribute to broaden knowledge about the autochthonous strains of this poorly studied fermented product, thus helping to select an appropriate combination of potential starter cultures to improve llama sausage safety and quality

Variations in the Composition, Antioxidant and Antimicrobial Activities of Cystoseira compressa during Seasonal Growth

The underexplored biodiversity of seaweeds has recently drawn great attention from researchers to find the bioactive compounds that might contribute to the growth of the blue economy. In this study, we aimed to explore the effect of seasonal growth (from May to September) on the in vitro antioxidant (FRAP, DPPH, and ORAC) and antimicrobial effects (MIC and MBC) of Cystoseira compressa collected in the Central Adriatic Sea. Algal compounds were analyzed by UPLC-PDAESI- QTOF, and TPC and TTC were determined. Fatty acids, among which oleic acid, palmitoleic acid, and palmitic acid were the dominant compounds in samples. The highest TPC, TTC and FRAP were obtained for June extract, 83.4 4.0 mg GAE/g, 8.8 0.8 mg CE/g and 2.7 0.1 mM TE, respectively. The highest ORAC value of 72.1 1.2 M TE was obtained for the August samples, and all samples showed extremely high free radical scavenging activity and DPPH inhibition (>80%). The MIC and MBC results showed the best antibacterial activity for the June, July and August samples, when sea temperature was the highest, against Listeria monocytogenes, Staphylococcus aureus, and Salmonella enteritidis. The results show C. compressa as a potential species for the industrial production of nutraceuticals or functional food ingredients

Reduction of EpCAM-Positive Cells from a Cell Salvage Product Is Achieved by Leucocyte Depletion Filters Alone

Intraoperative cell salvage reduces the need for allogeneic blood transfusion in complex cancer surgery, but concerns about the possibility of it re-infusing cancer cells have hindered its application in oncology. We monitored the presence of cancer cells on patient-salvaged blood by means of flow cytometry; next, we simulated cell salvage, followed by leucodepletion and irradiation on blood contaminated with a known amount of EpCAM-expressing cancer cells, assessing also residual cancer cell proliferation as well as the quality of salvaged red blood cell concentrates (RBCs). We observed a significant reduction of EpCAM-positive cells in both cancer patients and contaminated blood, which was comparable to the negative control after leucodepletion. The washing, leucodepletion and leucodepletion plus irradiation steps of cell salvage were shown to preserve the quality of RBCs in terms of haemolysis, membrane integrity and osmotic resistance. Finally, cancer cells isolated from salvaged blood lose their ability to proliferate. Our results confirm that cell salvage does not concentrate proliferating cancer cells, and that leucodepletion allows for the reduction of residual nucleated cells, making irradiation unnecessary. Our study gathers pieces of evidence on the feasibility of this procedure in complex cancer surgery. Nevertheless, it highlights the necessity of finding a definitive consensus through prospective trials

Mediterranean Spontaneously Fermented Sausages: Spotlight on Microbiological and Quality Features to Exploit Their Bacterial Biodiversity

: The wide array of spontaneously fermented sausages of the Mediterranean area can represent a reservoir of microbial biodiversity and can be an important source of new technological and functional strains able to preserve product properties, counteracting the impoverishment of their organoleptic typical features due to the introduction of commercial starter cultures. We analysed 15 artisanal salamis from Italy, Spain, Croatia and Slovenia to evaluate the microbiota composition, through culture-dependent and culture-independent techniques (i.e., metagenomic analysis), chemical-physical features, biogenic amines and aroma profile. The final pH varied according to origin and procedures (e.g., higher pH in Italian samples due to long ripening and mold growth). Lactic acid bacteria (LAB) and coagulase-negative cocci (CNC) were the dominant population, with highest LAB counts in Croatian and Italian samples. Metagenomic analysis showed high variability in qualitative and quantitative microbial composition: among LAB, Latilactobacillus sakei was the dominant species, but Companilactobacillus spp. was present in high amounts (45-55% of the total ASVs) in some Spanish sausages. Among staphylococci, S. epidermidis, S. equorum, S. saprophyticus, S. succinus and S. xylosus were detected. As far as biogenic amines, tyramine was always present, while histamine was found only in two Spanish samples. These results can valorize the bacterial genetic heritage present in Mediterranean products, to find new candidates of autochthonous starter cultures or bioprotective agents
