Estudi exploratori comparatiu del coneixement didàctic del contingut sobre piles galvàniques de professors de secundària en exercici i en formació

2021

En este estudio exploratorio se evalúa el conocimiento didáctico del contenido (CDC) sobre pilas galvánicas de profesores de secundaria en formación y en ejercicio. Además, este conocimiento se ha relacionado con los enfoques de enseñanza que prefieren. Para este propósito, se ha adaptado el instrumento CoRe de Loughran, Mulhall y Berry (2004) considerando dos situaciones: pila Daniell y pila voltaica simple. La muestra se compuso de 25 profesores en formación y de 15 profesores en ejercicio. El análisis de los resultados obtenidos hasta ahora sugiere que, en primer lugar, el CDC de los profesores de secundaria sobre pilas galvánicas no es el deseable; en segundo lugar, el CDC de los profes…

Kandydat PSL "Wyzwolenie" pierwszym prezydentem Polski, czyli wielka gra Stanisława Thugutta w grudniu 1922 roku

2019

In December 1922, the first presidential election in history took place in Poland. Voting was not universal because the National Assembly made their choice. One of the candidates for the office of president was proposed by Stanislaw Thugutt. He was the leader of the Polish People’s Party “Wyzwolenie/Liberation”. PPP “Wyzwolenie/Liberation” was one of the largest peasant parties in interwar Poland. In comparison with the largest peasant party in the Second Polish Republic – the Polish People’s Party “Piast” was a leftist party. On December 9, 1922, both parties supported the same candidate in a decisive vote. It was Gabriel Narutowicz, who was then the Minister of Foreign Affairs. In additio…

The impact of liquid-pressurized extracts of Spirulina, Chlorella and Phaedactylum tricornutum on in vitro antioxidant, antiinflammatory and bacteria…

2022

The impact of Spirulina, Chlorella and Phaeodactylum tricornutum (P. tricornutum) microalgal extracts obtained by pressurized liquid extraction (PLE) on antioxidant and anti-inflammatory activities, microbial growth and in vitro gut microbiota composition was evaluated. PLE, compared to conventional extraction, led to a significant (p < 0.05) increase in proteins, carbohydrates, polyphenols, and antioxidant capacities of the three microalgal extracts. Moreover, Spirulina and P. tricornutum extracts significantly (p < 0.05) reduced the in vitro activation of the inflammatory NF-κB pathway. The microalgal extracts had also an inhibitory effect on the pathogenic bacteria while potential benefi…

Risk factors of Oral cancer- A hospital based case control study

2018

Background Oral cancer is a highly prevalent malignancy in Pakistan. Among various risk factors associated with this neoplasm, habits such as smoked and smokeless tobacco usage, betel quid, and betel nut consumption are the major culprits in our society. In the present study, we aimed to ascertain prevalent risk factors for OC in our population and to compare our findings with healthy controls to establish their significance. Material and methods A hospital-based case control study was conducted at Dow University of Health Sciences, Pakistan from January 2015 - September 2016. Information pertaining to unhealthy oral habits was obtained from 62 oral cancer patients (cases) and 62 healthy co…

Facial masks in children: the position statement of the Italian pediatric society

2020

AbstractFacial masks may be one of the most cost-effective strategies to prevent the diffusion of COVID 19 infection. Nevertheless, fake news are spreading, alerting parents on dangerous side effects in children, such as hypercapnia, hypoxia, gut dysbiosis and immune system weakness. Aim of the Italian Pediatric Society statement is to face misconception towards the use of face masks and to spread scientific trustable information.

Evaluation of Changes in Gut Microbiota in Patients with Crohn’s Disease after Anti-Tnfα Treatment: Prospective Multicenter Observational Study

2020

Background: Crohn’s disease is believed to result from the interaction between genetic susceptibility, environmental factors and gut microbiota, leading to an aberrant immune response. The objectives of this study are to evaluate the qualitative and quantitative changes in the microbiota of patients with Crohn’s disease after six months of anti-tumor-necrosis factor (anti-TNFα) (infliximab or adalimumab) treatment and to determine whether these changes lead to the recovery of normal microbiota when compared to a control group of healthy subjects. In addition, we will evaluate the potential role of the Faecalibacterium prausnitzii/Escherichia coli and Faecalibacterium prausnitzii/Clostridium…

Proteolytic Processing ofBacillus thuringiensisCryIIIA Toxin and Specific Binding to Brush-Border Membrane Vesicles ofLeptinotarsa decemlineata(Color…

1996

Abstract The mode of action of Bacillus thuringiensis insecticidal proteins in lepidopteran insects is known to involve five steps: ingestion, solubilization, protease activation, binding to midgut membrane receptors, and disruption of the intestinal membrane. Two of these steps, protease activation and binding to midgut membrane receptors, have been analyzed in the major potato pest, the coleoptera Leptinotarsa decemlineata (Colorado potato beetle). Unlike recently proposed, after treatment of the coleopteran-specific B. thuringiensis toxin CryIIIA with gut content from the Colorado potato beetle, a 42-kDa processing polypeptide has been identified. The study of binding to midgut membrane …

Investigation of the steps involved in the difference of susceptibility of Ephestia kuehniella and Spodoptera littoralis to the Bacillus thuringiensi…

2011

BUPM95 is a Bacillus thuringiensis subsp. kurstaki strain producing the Vip3Aa16 toxin with an interesting insecticidal activity against the Lepidopteran larvae Ephestia kuehniella. Study of different steps in the mode of action of this Vegetative Insecticidal Protein on the Mediterranean flour moth (E. kuehniella) was carried out in the aim to investigate the origin of the higher susceptibility of this insect to Vip3Aa16 toxin compared to that of the Egyptian cotton leaf worm Spodoptera littoralis. Using E. kuehniella gut juice, protoxin proteolysis generated a major band corresponding to the active toxin and another band of about 22kDa, whereas the activation of Vip3Aa16 by S. littoralis …

Resistance toBacillus thuringiensis Cry1Ac toxin in three strains ofHeliothis virescens: Proteolytic and SEM study of the larval midgut

1999

In a previous study, we demonstrated that resistance to Bacillus thuringiensis toxins in Heliothis virescens might be related to differences in the composition of the proteolytic extracts from insect midgut. There, we found specific proteolytic bands present in the gut extracts of the resistant strain and absent from the susceptible one. Here we report related facts using a new resistant strain (KCB) and a cross between the two strains used in our previous study. As would be expected, no quantitative differences in total proteolytic activity were found between the strains, although qualitative differences related to the presence or absence of specific proteolytic activity bands using SDS-PA…
