Abstract:Pulmonary infarction (PI) is the result of an occlusion of a distal pulmonary artery. This results ischemia and possible hemorrhage or tissue necrosis of the pulmonary tissue distally. It is caused by another primary disease state, most commonly pulmonary embolism (PE). Understanding the broad differential diagnosis associated with PI is important, as associated signs and symptoms have limited specificity and PI may be the first indication of such a significant underlying pathology. The reported annual incidence of PE varies between 75 and 269 cases per 100,000 persons, and mortality rates as high as 28% have been described. Although the dual blood supply to the lungs, i.e. the pulmonary and the bronchial circulation, is thought to be protective against pulmonary ischemia, pulmonary infarction can be found in 10 to 50% of all patients with PE. The lungs receive deoxygenated blood from the pulmonary arteries (low pressure, high flow circulation) and oxygenated blood from the bronchial arteries (at systemic pressure, i.e. 6 times that of the pulmonary arteries). The function of the pulmonary circulation is mainly gas exchange, whereas the bronchial circulation supplies the bronchial walls, the visceral pleura and the lung parenchyma with oxygenated blood (next to direct passive diffusion of oxygen in the latter). This dual blood supply has been thought to be protective against ischemic injuries of the lungs. Animal models have shown that lung tissue may stay viable after ligation of the supplying pulmonary artery, where perfusion is maintained by the bronchial circulation. In this study, we give evidenc to the patterns of bronchial arteries undergo smooth muscle wall hypertrophy and dilate to direct more oxygenated blood to ischemic lung tissue, and eventually increase in number. Even so, obstruction of a pulmonary artery by acute PE can cause difference in severity in pulmonary infarction.
Abstract:Tai Chi Chuan, simply known as Tai Chi, is an ancient Chinese practice that combines fluid body movements with deep breathing to promote mind-body balance and facilitate the flow of internal energy. It is called Qi. This discipline has become popular worldwide due to its health benefits. Fifty community-dwelling adults aged 60 years and older with fibromyalgia participated in the study. The participants attended eight 50-minute sessions per month over a three-month period, completing a total of 24 sessions. The sessions were conducted online rather than in person due to the COVID-19 pandemic. Research has confirmed that Tai Chi can improve aerobic capacity, muscular strength, balance, and psychological well-being, as well as enhance health-related quality of life. Recent studies have also demonstrated that Tai Chi is safe and effective for various conditions, including neurological, rheumatological, orthopaedic, cardiovascular, chronic obstructive pulmonary diseases, and breast cancer. The results show that the treatment has also been significantly effective from a statistical standpoint.
Abstract:The cosmological theories proposed so far do not postulate a common way of creation that can guide the entire line of growth of the universe, from elementary particles to living beings. But everything consists of the same basic components, combined and regulated differently: elementary particles, atoms and molecules make up celestial bodies, solar systems, single and pluricellular organisms, plants and animals. Common constituents are compatible with a common origin and with an incremental and selective development method. One possible common mode is that the Universe was formed according to an evolutionary method based on natural selection, the same process which then allowed the differentiation of biological species. This unique process may have guided from the beginning the development of the fundamental constituents of matter in the primitive universe and then created the other cosmic structures through the evolution of those elementary particles, up to organic molecules and biological beings. A process of this kind is a slow and gradual process, not based on a sudden event but on the progressive increase in the complexity of the structures present in the Universe, regulated by the selection of the most suitable and stable forms. For the relativistic relationship between energy, mass and velocity, we can think that the Universe was formed at the same time as the formation of elementary structures, slowly in a spacetime that was created in parallel: elementary particles created an initial infinitesimal spacetime system that then grew as more matter formed. The incremental creation of the cosmos would also concern forces and physical laws, which may have undergone the same evolutionary process from the most primordial and simple forms to the present, in proportion to the development of the whole system. This modality could justify the current simultaneous presence of quantum and relativistic laws at different levels (atomic and gravitational), as well as the coexistence of different species in different environments. This evolutionary modality is reflected in the fact that atoms, celestial bodies, chemical compounds, the general structure of the universe, physical laws and biological beings show the presence of stable entities selected among the many theoretically possible or unstable.

Abstract:The phenomenon of entrepreneurship nowadays plays an important role in every country as it affects all areas of its economic and social life, including job creation and economic restructuring. In this article, we will examine the research and studies conducted by the Global Entrepreneurship Monitor, focusing on two countries, Morocco and France, since 2015 because Morocco joined the Global Entrepreneurship Monitor in this year. The objective is to explain and compare the figures, statistics, and studies carried out on female entrepreneurship in these countries. The findings show that female entrepreneurship in France is developing and continuing to progress despite the effect of the global COVID-19 pandemic, and the same is true for Morocco, which for its part has experienced a remarkable development in recent years, although it still lags behind France.
Abstract:ABSTRACT Aspergillus niger ANL301 B-1 β-glucosidase was investigated on its effectiveness in optimizing protein contents and cyanide concentrations of cassava peels. Freshly harvested cassava tubers peels were dried in oven at 70oC for 36 hours and milled into fine particles using micro millers. Two 250ml sterilized conical flasks were used for this study, each containing 50g of the cassava peel flour in triplicates. Thirty (30) ml of sterile basal medium was added and thoroughly mixed. The flasks and their contents were sterilized by placing in boiling water at 100oC in a GFL brand water bath for 5minutes and in the autoclave at 121oC for 15 minutes. After cooling, one ml of spore suspension of A. niger was aseptically introduced into the first set of the flasks plugged with cotton wool and dried in the oven at 600C for 24 hours.The second set of flasks had no inoculums, were plugged with cotton wool and dried at room temperature. Results showed that fermentation of cassava peels by solid state fermentation using the A. niger significantly (P < 0.05) enriches the protein content of the waste and drastically lowering the cyanide concentration The significant changes in crude protein and cyanide contents after fermentation suggests it could be used as a good source of protein in compounding animal feeds. These findings will facilitate the development of an improved method for enhancing the nutritional value of cassava peels and other waste products.
