Distribution regarding bacteriocin genes within the lineages associated with Lactiplantibacillus plantarum.
In preliminary bioprinting experiments using NIH 3T3 cells, excellent cell viabilities of more than 95% were achieved. The particularly interesting feature of this novel material is that it can be used as a printing support in hybrid bioink systems and sacrificial bioink due to rapid dissolution at physiological conditions.
A high priority for study during the pandemic of SARS-CoV-2 is the safety at work of hospital staff taking care of COVID-19 patients. The authors decided to analyze the results of opportunistic screening for anti-SARS-CoV-2 antibodies among employees of a COVID-19-dedicated centre. Objectives The authors aimed to investigate if potential exposition to SARS-CoV-2 antigens is reflected in the results of serological studies.

Every employee who took at least one test between 21st April and 20th July was included in the study. Every testassessed levels of immunoglobulin G (IgG) and immunoglobulin M+A (IgM+IgA). Employees were divided in terms of having contact with COVID-19 patients and participating in aerosol-generating procedures.

Results of 2455 tests taken by 1572 persons were analyzed. 357 (22.7%) participants had at least one positive or equivocal result during the observation period. Linear mixed models revealed gradual increases in mean levels of both IgG and IgM+IgA antibodies among employees with all negative results. The rate of change was higher among persons having direct contact with COVID-19 patients and the highest rate of change was observed among person participating in aerosol-generating procedures.

We detected developing humoral immune response to a new set of antigens of coronavirus among studied group. It is possible that employees of COVID-19-dedicated centres have regular contact with non-infectious amounts of SARS-CoV-2 or its antigens.

The best well-known vaccines have utilized either mRNA or an adenovirus vector to direct human cells to produce the spike protein against which the body produces mostly neutralizing antibodies. However, recent reports have raised some skepticism as to the biologic actions of the spike protein and the types of antibodies produced. One paper reported that certain antibodies in the blood of infected patients appear to change the shape of the spike protein so as to make it more likely to bind to cells, while other papers showed that the spike protein by itself (without being part of the corona virus) can damage endothelial cells and disrupt the blood-brain barrier. These findings may be even more relevant to the pathogenesis of long-COVID syndrome that may affect as many as 50% of those infected with SARS-CoV-2. In COVID-19, a response to oxidative stress is required by increasing anti-oxidant enzymes. In this regard, it is known that polyphenols are natural anti-oxidants with multiple health effects. Hence, there are even more reasons to intervene with the use of anti-oxidant compounds, such as luteolin, in addition to available vaccines and anti-inflammatory drugs to prevent the harmful actions of the spike protein.Using a within-subject design we compared the individual responses between drop-set (DS) vs. traditional resistance training (TRAD) (n=16) and crescent pyramid (CP) vs. TRAD (n=15). Muscle cross-sectional area (CSA), leg press and leg extension 1 repetition maximum (1-RM) were assessed pre and post training. At group level, CSA increased from pre to post (DS 7.8% vs. TRAD 7.5%, P=0.02; CP 7.5% vs. TRAD 7.8%, P=0.02). All protocols increased the 1-RM from pre to post for leg press (DS 24.9% vs. TRAD 26.8%, P less then 0.0001; CP 27.3% vs. TRAD2 6.3%, P less then 0.0001) and leg extension (DS 17.1% vs. TRAD 17.3%, P less then 0.0001; CP 17.0% vs. TRAD 16.6%, P less then 0.0001). Individual analysis for CSA demonstrated no differences between protocols in 15 subjects. For leg press 1-RM, 5 subjects responded more to TRAD, 2 to DS and 9 similarly between protocols. In TRAD vs. CP, 4 subjects responded more to CP, 1 to TRAD and 10 similarly between protocols. For leg extension 1-RM 2 subjects responded more to DS, 3 to TRAD and 11 similarly between protocols. Additionally, 2 subjects responded more to CP, 2 to TRAD and 11 similarly between protocols. In conclusion, all protocols induced similar individual responses for CSA. For 1-RM, some subjects experience greater gains for the protocol performed with higher loads, such as CP.Dance injury research has mainly focused on ballet and modern dance with little data on musical theatre dancers. The purpose was to assess the incidence and severity of injuries in a musical theatre dance college over a 5-year period; 198 pre-professional musical theatre dancers (3 cohorts on a 3-year training course) volunteered for the study; 21 students left the course over the study period. Injury aetiology data were collected by an in-house physiotherapy team. Differences between academic year and sex were analysed using a Poisson distribution model; significant difference was set at p≤0.05. In total, 913 injuries were recorded, and more injuries occurred in academic year 1 than year 2 and 3. Overall injury incidence was 1.46 injuries per 1000 hours (95% CI 1.34, 1.56); incidence significantly decreased between year 1, 2 and 3 (p less then 0.05). There was no significant sex difference for incidence or severity. Most injuries were classified as overuse (71% female, 67% male). Pre-professional musical theatre dancers report a high proportion of lower limb and overuse injuries comparable to other dance genres. Unlike other studies on pre-professional dancers, injury incidence and severity decreased with academic year, even though workload increased across the course.
