Authors: DO Chris Moriarty , Monfared Sina Hassan Beygi , Wason Shaun E. L. 
Published: March 2023

Abstract

PURPOSE
Brazilian jiu-jitsu (BJJ), a grappling-based martial art, has faced unique challenges during the COVID-19 pandemic primarily due to universal masking and social distancing. The objective of this study was to investigate the impact of COVID-19 on BJJ academies and owner implementation of risk-mitigation strategies during the early phase of the pandemic. We then explored the association between cultural, demographic, academy-specific variables, and owners’ attitudes to the implementation of risk-mitigation strategies.
METHODS
After IRB approval, we surveyed BJJ practitioners using a 35-question online survey distributed electronically between June-August 2020.
RESULTS
183 (66%) respondents who owned their gym completed the survey. All academies closed (n = 183,100%) and most academy closures were self-imposed (n = 104,57%). Most academies implemented sanitation (n = 169,92%) or exposure non-training-related change (n = 166,91%). There was no association among sociodemographic variables, owners' attitudes regarding the seriousness of the COVID-19 pandemic, and implementation of risk-mitigation strategies.
CONCLUSIONS
To our knowledge, this is the first study examining the short-term effect of COVID-19 on BJJ training and implementation of risk-mitigation strategies. All respondents closed their academies during the pandemic, and most respondents reported changes to their sanitation, exposure, and screening practice. The long-term effects of COVID-19 on the sport remains largely unknown.

Abstract
Purpose

To investigate partners’ perception of women’s perception regarding long-term psychological outcomes after risk-reducing mastectomy (RRM) and immediate breast reconstruction (IBR) by investigating their perception of the women’s long-term evaluation regarding satisfaction with aesthetic outcome, body image, and sexuality, and to compare partners’ and women’s levels of anxiety/depressive symptoms and health-related quality of life (HRQoL).

Methods

Partners responded to the same questionnaires as the women without modifications. The partners responded to HAD and SF-36 from their own perspective, and the remaining questionnaires (EORTC QLQ-BRR26, BIS, and SAQ) from their perception of how the women would have responded. The responses of the partners were compared with the responses of the women, as well as with the HRQoL of the normative Swedish population.

Results

Thirty-six (60%) partners participated. The partners’ perception of the women’s satisfaction with the aesthetic outcome was lower compared with the women’s own perceptions (p<0.05). Partners’ perception of women’s perceived level of body image problems was higher than the women’s response (p<0.05). There was an agreement in the perception of the sexuality-related questions. Partners and women had in general higher levels of HRQoL compared with the age-standardised normative Swedish population.

Conclusion

This study, albeit small, showed that partners overestimated women’s dissatisfaction with long-term aesthetic outcome and body image, while there were no discrepancies between the two groups regarding aspects of sexuality. Both groups demonstrated high levels of HRQoL long-term after RRM and IBR. RRM is a personal choice, but knowledge about long-term effects involve both women and their partners.
Referral rate, profile and degree of control of patients with familial hypercholesterolemia. Data from a single lipid unit from a Mediterranean area
Authors: SERRA-PLANAS Enric 
Published: March 2023

Abstract
Background
The challenging rigorous management of hypercholesterolemia promotes referral to specialized units. This study explored the need, based on referral rate and cardiovascular (CV) risk factors control in patients evaluated for familial hypercholesterolemia (FH), for a lipid unit (LU).
Methods
Of a 4-year period, 340 referrals to our unit were analysed to establish lipid disorders referral rate. Moreover, 118 patients referred for potential FH during the period 2010–2018 (52.4 ± 13.9 years, 47.5% male, Caucasian, 25.4% obese, 33.1% smokers and 51.6% with some glycaemic alteration) were investigated. The Dutch Lipid Clinic Network (DLCN) score, type and dose of lipid-lowering drugs, lipid profile including lipoprotein (a) (Lp(a)) and the presence of plaques with carotid ultrasound (CU) were recorded.
Results
Lipids represented 6.2% of referrals (38 patient-years) requiring a 2–3 hour weekly monographic outpatient consultation. Potencial FH sample displayed DLCN score ≥ 6 in 78% and modifiable CV risk factors in 51%. Only 22% achieved tight disease control despite intensive treatment. Statin-ezetimibe combination treatment group achieved better goal (73.0% vs. 45.5%, p = 0.003) and rosuvastatin group higher proportion of prediabetes (60.9% vs. 39.1%, p = 0.037). Neither CU nor Lp(a) positivity linked with established CV disease patients but higher Lp(a) concentrations were detected between them (102.5 (26.3–145.8) vs. 25.0 (13.0–52.0), p = 0.012).
Conclusions
Referral rate, degree of control, and proportion of modifiable CV risk factors in FH patients demonstrate the need for a LU in our area as well as changes in treatment and management.
Influence of Gas Pressure on the Magnetized Plasma Parameters of Laser-Induced Breakdown

Published: March 2023

Abstract
In this study, the effect of environment gas and working pressure of laser-induced breakdown spectroscopy (LIBS) from ZnO: Al composite target (AZO) enhanced by an external magnetic field on the magnetized characteristics and emission spectra of plasma were investigated. The plasma was induced by a Q-switched nanosecond Nd: YAG laser at a constant pulse laser energy of 300 mJ at different pressures of 0.08, 0.2, 0.4, and 760 Torr in air and argon gas. The atomic and ionic emission lines increased in intensity directly with the working pressure. The plasma temperature (Te) and electron number density (ne) were determined at the different environmental conditions according to Boltzmann-Plot, and Stark broadening effect, respectively. The ne increased with increasing pressure as a result of increasing electron-atom collisions. While Te reduced with working pressure. The plasma parameters in different conditions satisfied the plasma criteria. The line profile appeared with high broadening at atmospheric pressure compared with vacuumed plasma. The Larmur radius reduced while the confinement factor β increased with working pressure. From another hand, using Ar instead of air caused to slightly reduced in ne at low pressure of 0.08 Torr, and slightly increased at 0.4 Torr pressure. While the Te has the opposite behavior. Due to the evidence variation of plasma number density with pressure, the plasma frequency values increased with increasing the pressure, with higher values in Ar than air at 0.4 Torr, while slightly lower in Ar than air at 0.08 Torr. λD and Nd have opposite behavior with working pressure.
Smartphone-based colourimetric detection of analytes after pre-concentration onto a hectorite clay-hydroxyethylcellulose hybrid
Authors: Mazarakis Anastasios Phoebus , Tsotsou Georgia Eleni 
Published: March 2023

Abstract
This paper describes a new, smartphone-enabled quantitative analysis format, based on analyte pre-concentration by adsorption onto Bentone LT. Bentone LT pellet isolation comes after adsorption, followed by in-situ application of an analyte-selective chromogenic reaction. Resulting pellet colouration is captured by the phone’s integrated camera and assessed using the free open-source image processing software, ImageJ. Responses are calibrated and quantified. We here demonstrate the extended applicability of the proposed methodology for the smartphone-based quantification of specific model analytes. The smartphone-based assay is reliable in quantifying model analytes, alone or in mixture, from dilute aqueous solutions and depicts accurately the adsorption behaviour followed photometrically in solution. Its quantification capability was found to extend below that of the respective chromogenic reaction in solution. It is likely that the applicability of the proposed quantitative analysis format extends to other analytes where analyte-specific colour formation is feasible.

Published: March 2023

Abstract
Sago (Metroxylon sagu) processing in Meranti Islands Regency is currently still conventional and only produces semi-finished materials in the form of sago starch, so it is important to recognize other potentials of this sago through its anatomical characteristics, lignin, and cellulose content. The anatomical features of fiber dimensions were observed by making maceration preparations using the Schultze method. The obtained wood anatomy data were analyzed descriptively and presented in tables, figures, and photographs. SNI 14-0492-1989 is used to determine lignin content, and SNI 14-0444-1989 is used to determine cellulose content. Especially for road reinforcement, which has a high potential. The results obtained by the two types of sago in Meranti Islands Regency, Riau Province include class II fiber and lignin content (23.14% and 22.14%), as well as cellulose content (44.12% and 42.4%), and have the potential to be used as reinforcement on road subgrades. According to the findings of this study, sago bark waste has a high potential for processing in the industrial sector, particularly for road reinforcement, which has a high potential.
Evaluation of Oxyfluorfen Formulations for Cabbage Weed Control
Authors: Grabowski J. M. , Hopen H. J. 
Published: March 2023

Abstract
Oxyfluorfen exhibited intraspecific selectivity among cabbage (Brassica oleracea L. var capitata) cultivars. The wettable powder (WP) and granular (G) formulations were less toxic to cabbage plants than the emulsifiable concentrate (EC) formulation when applied at 0.56 kg ai/ha. Susceptibility to oxyfluorfen injury decreased with plant age. Plants treated with 0.56 kg ai/ha of the WP formulation at the 2-leaf growth stage showed greater injury than plants treated at the 6–8 leaf stage. Oxyfluorfen injury symptoms from an application of 0.28 kg ai/ha EC formulation were increased when plants were treated previously with 1.12 kg ai/ha EPTC. Selectivity may be provided by cuticular wax on the cabbage leaves which prevents spray retention and penetration. Cultivars with increased cuticular wax showed reduced injury from oxyfluorfen application.
Seasonal Osmotic Relations in Apple Leaves of Different Ages
Authors: Lakso A. N. , Geyer A. S. , Carpenter S. G. 
Published: March 2023

Abstract
Seasonal changes in the relationship between leaf conductance and total water potential in mature apple (Malus domestica Borkh.) shoot leaves were found to be mediated by osmotic adjustment, not changes in the total water potential–relative water content relationship. Leaves at the growing shoot tip were found to have a much higher (1.0 to 2.0 MPa) osmotic potential than mature leaves and showed no seasonal osmotic adjustment, while mature, fully expanded leaves on the same shoots did adjust osmotically. Leaf osmotic potentials differed little among exposed leaves on a shoot once fully expanded.

Published: March 2023

It is doubtful that many of today's dairy herds, fed rations balanced to NRC standards, experience reproductive problems solely because of nutrition. Nutrients and how their deficiencies and excesses affect reproduction have been reviewed.1,6 Further research is needed to investigate combinations of nutrients and the subsequent effect on reproduction.
Some veterinary practitioners are convinced that there are profound interrelationships between the nutritional status of dairy cattle and their reproductive performance. This clinical impression was fostered because in many cases regular reproductive tract examinations alone were not adequate to ensure good herd reproductive health and reproductive efficiency. In some cases this impression is justified, but in many cases nutrition is the scapegoat for environment, stress, disease and the main problem of missed heats and other poor reproductive management practices.
This paper will discuss body condition scoring cows on a large dairy farm in north Florida, and its effect upon reproductive performance and 305-day mature equivalent four percent fat-corrected milk (ME 305).
Cow/Calf Production Records
Authors: Spire Mark F. 
Published: March 2023

The use of records in a production medicine program can vary from the simple to the complex. Regardless of the degree of sophistication in the system, records should accurately document events occurring in the herd. Historians and politicians frequently use the phrase. "How do we know where we are going, if we don't know where we have been?" Records leave a written documentation for others to follow.
The development of production medicine programs depend to a large degree on informaton transfer between the producer, veterinarian, and various resource people involved in production agriculture. This exchange of ideas and concepts should result in cost efficient beef production for the enterprise. Each person plays a significant role. The producer establishes goals for the operation and provides day-to-day observations and documentation. The veterinarian provides documentation, technical and decisionmaking skills. Resource personnel provide the latest economic and technical information. The use of production records allows all parties involved to evaluate the operation's performance from a production and economic perspective while taking advantage of available technology.

Published: March 2023

Various antibiotics have been used in the treatment of bacterial infections in domestic animals. In recent years, however, outbreaks of infections due to microorganisms resistant to antibiotics are often observed (1, 2, 3). The antibacterial quinolone derivatives does not show cross-resistance with antibiotics (4). AT-4526, 1-cyclopropyl-5,6,8-trifluoro-1 ,4- dihydro-7-(cis-3,5-dimethyl-1-piperazinyl)-4-oxoquinoline-3- carboxylic acid (Fig. 1), is a new quinolone derivative which was synthesized in 1986 (5). This compound, as well as the structurally related enrofloxacin (6), has a high order of activity against a broad spectrum of gram-positive, gram-negative bacteria, and Mycoplasma spp ..
This paper describes the in vitro and in vivo antibacterial activities of AT-4526 against field isolates in domestic animals and the comparison with those of enrofloxacin (ERFX), oxytetracycline (OTC), tylosin (TS), thiamphenicol (TP), kanamycin (KM) and ampicillin (ABPC).
Implementing Biosecurity in Beef and Dairy Herds
Authors: Thompson John U. 
Published: March 2023

The common disease prevention and control practices employed by the majority of beef and dairy herds today are inadequate to meet the future demands. They rely on visual observation, regulatory compliance, vaccination, and limited attention to biosecurity of the herds making animal additions.1
Bovine practitioners have been encouraged to increase their participation in nutritional, genetic selection, and financial and production record analysis for beef and dairy herds. Different surveys have indicated that cattle owners continue to look to the bovine practitioner primarily for the diagnosis and treatment of diseases and addressing the needs of the individual animal. Veterinarians can strengthen their position in the decision-making team by providing a herd biosecurity and biocontainment risk management assessment and protocol.
For this article, biosecurity will refer to attempts to prevent the entry of pathogens considered potentially harmful to the health and well-being of the herd. Practitioners are encouraged to expand the principles to include such things as genetics and nutrients. Biocontainment will refer to controlling the elements within a given population of cattle. Biocontainment strategies should apply to the management of epidemics within a herd and should address biosecurity failures.

Title: Updating Joglo Construction Without Four Saka guru (Case Study of Pendopo Pura Agung Blambangan of Banyuwangi)

Current architectural developments to maintain its sustainability have reached the awareness stage to explore the potential for the diversity of archipelago architecture, one of which is exploring the potential for the Joglo traditional house for the future. The demand for wide spans often comes to the fore, so it is not uncommon for new construction designs to respond to the demands for wide spans free from pillars. However, a solution is needed to solve this problem. The pillars and their frames are the main part of the main reinforcement system for the roof load as a whole, so they become prerequisites on behalf of the Joglo. This writing aims to analyze the updated form of construction without pillars that still maintain the Joglo form. The research method uses a qualitative descriptive approach by examining the process of eliminating the four pillars of teachers by analyzing the reliability of the structural system of the Puri Agung Blambangan pavilion and the Sabha Swagata Blambangan pavilion in Banyuwangi, East Java. The research results show how the construction of the four pillars and their frames are believed to be the main strength to withstand the roof’s weight. The construction system without the four pillars of the guru and their frames reduces the rigidity of the building because the strength is transferred to the pillars on the edges of the building and does not reflect the joglo structural and construction system. Many knot points have appeared without the pillars and the framework of a construction system, increasing the risk of collapse.
Is the presence of mosquitoes an indicator of poor environmental sanitation?
Authors: Olagunju Emmanuel Ajibola 
Published: March 2023

Abstract
The World Health Organization has designated mosquitoes as the most lethal animal since they are known to spread pathogen-transmitting organisms. Understanding the many environmental elements that contribute to the spread of these vectors is one of the many strategies used to stop them. If there are mosquitoes around people, it may indicate that there is not an appropriate environmental sanitation program in place in the community or region. Environmental sanitation involves improving any elements of the physical environment that could have a negative impact on a person's survival, health, or physical environment. Keywords containing ‘Aedes,’ ‘Culex,’ ‘Anopheles,’ ‘dengue,’ ‘malaria,’ ‘yellow fever,’ ‘Zika,’ ‘West Nile,’ ‘chikungunya,’ ‘resident,’ ‘environment,’ ‘sanitation,’ ‘mosquito control,’ and ‘breeding sites’ of published articles on PubMed, Google Scholar, and ResearchGate were reviewed. It was discovered that the general population should be involved in mosquito and mosquito-borne disease control. Collaboration between health professionals and the general population is essential. The purpose of this paper is to increase public awareness of environmental health issues related to diseases carried by mosquitoes.

ABSTRACT

In this work, Mn2O3/Fe2O3 (MFO) was synthesized and used to activate monopersulfate (MPS) for the degradation of ciprofloxacin (CIP). The effect of several parameters was studied on CIP degradation. Under the optimum conditions (pH = 6.3 (natural pH), MFO = 300 mg/L and MPS = 2 mM), around 92% of CIP was decomposed. Nitrite, phosphate and bicarbonate ions had a strong inhibitory effect on the MFO/MPS process while the effect of chloride and nitrate ions was neutral. The catalytic activity of MFO was also studied by other chemical oxidants such as peroxydisulfate, periodate, hydrogen peroxide, percarbonate and peracetic acid. Scavenging tests showed that the role of sulfate radicals is more than hydroxyl radicals. MFO exhibited high catalytic activity in four recycling with insignificant leaching of Mn and Fe. During CIP oxidation, 45.5% carbon mineralization occurred and antibacterial activity of treated CIP solution was reduced. Finally, MFO/MPS was applied on actual wastewater (hospital effluent) and the results showed that MFO/MPS can be considered as a practical method for the treatment of contaminated water with emerging pollutants.

Aims:
Synthesis of 1,4-Dihydropyridines (1,4-DHP) using heterogeneous catalyst un-der mild condition

Objective:
Our objective is to explore new applications of non-metal heterogeneous catalysts in the synthesis of 1,4-DHP derivatives in a greener and more efficient approach.

Methods:
A greener and more efficient method for the synthesis of 1,4-DHPs and an asymmetric 1,4-DHP (Felodipine drug) was successfully developed in high yields using a heterogeneous SBA-15-SO3H catalyst.

Results:
A series of symmetric 1,4-DHP and an asymmetric 1,4-DHP (Felodipine drug) were suc-cessfully prepared in high yields using a heterogeneous SBA-15-SO3H catalyst

Conclusion:
The catalyst, SBA-15-SO3H, exhibited an efficient catalyst activity for the synthesis of 1,4-DHP derivatives in high yields from the aldehyde, β-ketoester, and NH4OAc as a nitrogen source under mild conditions and short reaction time. Bronsted acid sites of this solid catalyst were figured out to play a key role in this transformation. Interestingly, our catalyst is air-stable and can be recycled at least 5 times without losing catalytic activity.
