Stimulatory effects of DB-c-AMP and adrenaline on myocardial contraction and 45Ca exchange. Experiments at reduced calcium concentration and low freq…
1973
The effects of adrenaline (2.2×10−6 M) and cyclic N6-2′-O-dibutyryl-adenosine-3′,5′-monophosphate (DB-c-AMP; 10−3 M) on mechanical performance, 45Ca uptake and total tissue calcium concentration were investigated in electrically stimulated left auricles isolated from female rats weighing 180–220 g. The experiments were performed at reduced [Ca]e of 0.45 mM and at various frequencies of stimulation (0–120 beats/min). In the first series of experiments 45Ca incubation time was 5 min. Under these conditions DB-c-AMP as well as adrenaline enhanced contractile force to 300–450% of the control values at all frequencies tested (Fig.1). This increase in contractile force was accompanied by a signif…
Home-Based Resistance Training for Older Subjects during the COVID-19 Outbreak in Italy: Preliminary Results of a Six-Months RCT.
2020
Background. The aim of this study was to evaluate the effect of a six-month home-based resistance-training program on muscle health and physical performance in healthy older subjects during the unique condition of home confinement caused by the COVID-19 pandemic. Methods. This was a randomized-controlled study that enrolled older participants that were allocated to either an experimental group performing the six-months exercise prescription (EXE) or a control group (CON). At the beginning (PRE), and after 6 months (POST), participants were assessed for muscle strength, balance, gait assessment and body composition by dual energy X-ray absorptiometry and magnetic resonance imaging. Normality…
Laparoscopy in Low-Income Countries: 10-Year Experience and Systematic Literature Review
2021
Laparoscopy is a procedure that ultimately reduces hospital stay time and speeds up post-operative recovery. It is mainly performed in high-income countries but its implementation in many low-and middle-income countries (LMICs) is increasing. However, no aggregate data exist regarding the outcomes of this procedure in resource-limited settings. We retrospectively reviewed all cases of laparoscopy recorded from January 2007 to March 2017 at the Department of Surgery of Beira to assess the related outcomes. Moreover, we performed a systematic review of the laparoscopic practices and outcomes in low-income countries. Data from the Department of Surgery of Beira identified 363 laparoscopic proc…
Chronic low level metribuzin exposure induces metabolic alterations in rats
2013
Abstract In this work we evaluated the in vivo effects of chronic metribuzin exposure at doses that mimic human exposure through diet. Male and female rats were fed a potato diet containing metribuzin at low doses (D1, 1.3 mg/kg or D2, 13 mg/kg) for 3 months. Plasma biochemical parameters (glucose, lipid, urea, creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST)), as well as lipid and protein contents, markers of oxidative stress in different organs (liver, adipose tissue, muscle, intestine) were determined. Our results showed that exposure to metribuzin induced a significant reduction in body weight, food intake and adverse alterations in biochemical parameters suc…

Obtaining information on expectations among dental students regarding their career planning was the main purpose of this observational online survey. The questionnaire was designed with 18 items in five different languages: English, French, German, Italian and Spanish. Data were collected on nationality, age, sex, country of residence, university attended, semester, expected year of graduation and expectations about future career. More than 3000 participants (n = 3851, 2863 females 74.34% and 988 males 25.66% with a sex ratio of 0.35) participated in the survey. Almost one-third (31.29%) of the participants plan to start their own practice at least three years after vocational training, a q…

The COVID-19 pandemic has become a public health emergency of international concern, which may have affected lifestyle habits and mental health. Based on national health profile assessments, this study investigated perceived changes of lifestyle habits in response to the COVID-19 pandemic and associations between perceived lifestyle changes and mental health in Swedish working adults. Among 5599 individuals (50% women, 46.3 years), the majority reported no change (sitting 77%, daily physical activity 71%, exercise 69%, diet 87%, alcohol 90%, and smoking 97%) due to the pandemic. Changes were more pronounced during the first wave (April–June) compared to the second (October–December). Women,…
Postural Sensorimotor Control on Anorectal Pressures and Pelvic Floor Muscle Tone and Strength: Effects of a Single 5P® LOGSURF Session. A Cross-Sect…
2021
Pelvic floor dysfunction (PFD) is a functional condition present most frequently in women. Despite pelvic floor muscle training being considered by the International Continence Society (ICS) as the first-line treatment in uncomplicated urinary incontinence, other more comprehensive postural methods as 5P® LOGSURF have emerged. This preliminary cross-sectional study explores the effects of a single 5P® LOGSURF session on pelvic floor muscle (PFM) tone and strength (MVC), resting anal tone, intrarectal pressure, and deep abdominal muscles activation. Thirty women were included (11 without PFD and 19 with PFD). Primary outcome measures were PFM tone, PFM MVC and resting anal tone and secondary…
Changes in carbohydrate metabolism in the eelanguilla anguilla, during short‐term exposure to diazinon
1997
The present communication deals with the effect of diazinon (0.042 mg/L) on the energy metabolism of the european eel Anguilla anguilla. Analysis of various parameters such as glycogen, lactate and glucose was made on different eel tissues after 6, 24, 48, 72 and 96 hr of diazinon exposure. Liver and muscle glycogen content decreased significantly (p < 0.05) from 6 to 96 hr pesticide exposure. Mean blood glucose values were elevated significantly after exposure to this sublethal diazinon concentration. Liver, blood and muscle lactate levels in fish increased during all exposure time being the highest at 96 hr exposure. Diazinon intoxicated fish showed signs of pesticide poisoning as muscula…
Evaluating the neurotoxic effects of lactational exposure to persistent organic pollutants (POPs) in Spanish children.
2012
Although the brain continues developing in the postnatal period, epidemiological studies on the effects of postnatal exposure to neurotoxic POPs through breast-feeding remain mostly inconclusive. Failure to detect associations between postnatal exposure and health outcomes may stem from the limitations of commonly employed approaches to assess lactational exposure. The aim of the present study was to assess whether lactational exposure to polychlorinated biphenyl-153 (PCB-153), dichlorodiphenyldichloroethylene (DDE), or hexachlorobenzene (HCB) as estimated with a physiologically based pharmacokinetic (PBPK) model, is associated with decrements in mental and psychomotor development scores of…
