Abstract
The skin is the largest organ in the human body and has a variable structure. It is divided into three layers: epidermis, dermis and hypodermis. Amid aesthetics, this structure works as a systemic administration port or as a route to administration of active principles. Invasive procedures, however, non-surgical, have been standing out and gaining space globally, as these are techniques that do not bring a significant risk of life or prolonged rest after treatment. The aim of this work is to raise the hypothesis of the effect of pressurized mesotherapy in relation to injectable mesotherapy. The method does not use needles; just pressurization to spread the product's principles in the skin tissue. Assets applied under pressure associated with the minimization of mechanical resistance by distending the elastic components of the skin with the use of skin folds have a better effect on aesthetic dysfunctions.

Abstract
A variety of pneumonia cases of unknown cause emerged in China in December 2019. A new virus belonging to the Coronaviridae family, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19). Within a few days, COVID-19 became a pandemic disease. This review aimed to investigate the possible implications of COVID-19 for human reproductive systems, as in previous studies ACE2 was highly expressed in some organs of these systems, such as the testicles. A total of 41 publications were found in the specialized databases and, after selection, 7 articles were used to build this study. Our results showed that the fever caused by COVID-19 has a negative effect on spermatogenesis, there is high expression of ACE2 in the testicles and in the uterine tubes and there is a higher level of transmembrane protease serine 2 (TMPRSS2), which is also responsible for the entry of the virus into the cell. Moreover, it was noted that there was viral genetic material in the semen and an increase in the serum concentration of luteinizing hormone (LH) in men and women, which could cause hypogonadism. Thus, we conclude that there is the possibility of infection and malfunction in the reproductive organs as well as the plausibility of sexual transmission of this disease. Further analysis must be carried out to prove the effects of COVID-19 on the human reproductive systems.

Abstract
Cellulase-free xylan-degrading enzyme preparations from Acrophialophora nainiana, Humicola grisea var. thermoidea and two Trichoderma harzianum strains were used as bleaching agents for Eucalyptus kraft pulp, prior to a chlorine dioxide and alkaline bleaching sequence. In comparison to the control sequence (performed without xylanase pretreatment), the sequence incorporating enzyme treatment was more effective. Removal of residual lignin was indicated by a reduction in kappa number. Overall, enzyme preparations from T. harzianum were marginally more effective in reducing pulp viscosity and chlorine chemical consumption and improving the brightness of the kraft pulp. However, the highest reduction in pulp viscosity was mediated by the xylanase preparation from A. nainiana. Xylanase pretreatment compares very favorably with that of chemical pulping.

Abstract
Trichoderma harzianum strains T4 and T6, Acrophialophora nainiana, and Humicola grisea var. thermoidea were screened for their ability to produce carbohydrate-degrading enzyme activities in a medium containing banana plant residue as the carbon source. The best balance of enzyme activities was obtained from cultures of H. grisea var. thermoidea. Xylanase activity from crude extract of A. nainiana had a maximum activity at pH 5.5-7.0 and a temperature range of 50-55 degrees C. It was stable up to 55 degrees C at pH 7.0 for at least 2 h. The fungi were also able to produce xylanase and pectinase activities when grown on extractives as substrate.
