Authors: Kaledin Anatoly , Malovichko Lyubov΄ , Rezanov Aleksandr , Drozdova Lyudmila 
Published: July 2022

The gray partridge (Perdix perdix L.) is a commercial bird species of the Central Ciscaucasia. In the steppe regions, these birds are found in cultivated gardens, vineyards, green belts along agricultural fields, roads, and railways, etc. The research objective was to study and analyze the diet of the gray partridge in different seasons in the Stavropol Region.
The study featured the food spectrum consumed by the gray partridge based on the contents of 42 stomachs and 26 crops of birds caught by hunters and hit by vehicles in various Stavropol biotopes in 2008–2021.
Gray partridges are phytophages, which means they feed mostly on plants and, to a lesser extent, on animals. Their autumn and winter diet includes green mass and wheat grains, seeds of cultivated and wild plants, and insect larvae. The gray partridge prefers weedy herbaceous plants: Polygonum aviculare, Echinochloa crus-galli, Amaranthus retroflexus, Chenopodium album, and Setaria viridis.
The data obtained can be used to assess food resources of commercial bird species, in gray partridge conservation projects, and winter feeding of birds.

Enzymatic protein hydrolysates of milk are used as a protein component of functional foods intended for children, athletes, and senior citizens. They are easy to absorb and possess hypoallergenic, antioxidant, antimicrobial, and antimutagenic properties. However, the peptides in their composition have a bitter taste, which limits the use of milk protein hydrolysates in food industry. Functional foods are often fortified with fat-soluble vitamins and other hydrophobic ingredients. They require multicomponent compositions that contain both hydrophilic and hydrophobic compounds. Complexes of β-cyclodextrins with peptides of whey protein hydrolyzates and fat-soluble vitamins can solve this problem.
The present research featured nanocomplexes of β-cyclodextrins with whey peptides and their multicomponent mixes with vitamins D3 and A. The methodology involved HPLC-MS, electrophoresis, thermogravimetry, and fluorimetry.
The obtained clathrates were used to develop new multicomponent compositions for functional nutrition. The article introduces a new production method for hypoallergenic peptide fractions with a molecular weight of 300–1500 Da from enzymatic whey protein hydrolyzates. The obtained peptides contained 6–14 amino acid residues and demonstrated hypoallergenic properties because they contained no antigenic determinants capable of causing IgE synthesis. The complexes of inclusion contained hydrolyzate peptides of dairy proteins and fat-soluble vitamins A and D3. The research revealed some antioxidant and antimutagenic properties, as well as the toxicological and hygienic profile of the clathrates. The resulting peptide clathrates had a less bitter taste. The inclusion complexes of fat-soluble vitamins D3:β-cyclodextrins, and A:β-cyclodextrins could be converted from an olive oil solution into a soluble powder. 100 g of the multicomponent composite contained 47.0 g of whey protein hydrolyzate of low molecular weight fraction peptides, 1.06 mg of vitamin D3 (42 500 IU), 3.44 mg of vitamin A (10 000 IU), and 1.54 g of olive oil. The article also describes the structural and functional properties of the inclusion complexes. Nanocomplexes of whey protein hydrolyzate of low molecular weight fraction peptides:β-cyclodextrins, D3:β-cyclodextrins, and A:β-cyclodextrins and their multicomponent composite were tested for toxicological and hygienic properties using Tetrahymena pyriformis. They appeared to belong to the 5th hazard class in terms of the average lethal dose (non-hazardous substances).
The obtained powder forms of fat-soluble vitamins and peptides are easily dosed and can be used to design new functional foods.
Traditional and Innovative Uses of Ultraviolet Treatment in the Dairy Industry
Authors: Riazantseva Ksenia , Sherstneva Natalia 
Published: July 2022

Traditional heat treatment methods are an integral part of the dairy industry. However, non-thermal methods ensure microbiological safety while preserving nutritional value of the dairy product, as well as improving its technological properties. The article reviews scientific and technical publications on ultraviolet (UV) treatment and its effect on the structure and properties of milk proteins and technological indicators of dairy products.
The review includes English and Russian articles published in Scopus, Web of Science, Elsevier, ResearchGate, and Elibrary databases in 2004–2021.
Most publications focus on maintaining the microbiological safety of milk and dairy products. Depending on the radiation dose, UV treatment was reported to cause denaturation and aggregation of milk proteins, followed by new cross-links. Conformational changes improve the functional properties of milk proteins, which makes them valuable food ingredients of film coatings and fermented milk products.
Electromagnetic treatment polymerizes whey proteins. This property can be used to produce strong film coatings with low vapor permeability. In fermented milk production, UV radiation improves such technological properties of yogurt as viscosity and water-holding capacity. The effect of electromagnetic waves on animal proteins and dairy products remains an understudied area of advanced research.

Abstract
Assessment of urban river sediment quality is paramount to understanding the impacts of urbanization on aquatic ecosystems and public health. The study evaluated the health impacts and sources of heavy metal pollutants in the Mangonbangon river, Tacloban City. With the abundance of heavy metal contaminants in the river sediment (Fe&gt;Mn&gt;Zn&gt;Cu&gt;Cr&gt;Ni&gt;Co), Hazard indices (HIs) ranged from 0.04 to 0.10 for adults and 0.31 to 0.90 for children suggesting little or no non-carcinogenic effects to the population. Lifetime cancer risk (LCR) is below the tolerable threshold of 10−4, with Co contributing 61% of the cancer risk. Using unconstrained ordination and the GIS-based method (UOGM), we showed two non-multidimensional scaling groups of pollutants distributed based on dwelling density, presence of informal settlers, and types of activity at the sample sites. Given that sampling was performed three years after the city-wide destruction by Typhoon Haiyan (Yolanda), our analysis indicates the return of anthropogenic activities and pollution-related health problems in Tacloban. Our results reinforce the urgent need for proper river management and economic zoning to help curb the rapidly growing heavy metal pollution problem at its earliest stage.
Phosphate drinking water softeners promote Legionella growth

Abstract
Phosphate-based drinking water softeners are commonly used to prevent scale formation in drinking water distribution infrastructure. The main reason for drinking water softening is primarily economic (protection of pipes and extension of equipment life), while the health aspect of such treatment is usually neglected. The aim of this work is to investigate the effects of phosphate-based drinking water softeners on growth stimulation of Legionella pneumophila. Bacterial growth was observed at two different phosphate concentrations. On average, an increase in growth of 1.19–1.28 log CFU/mL was observed in selected samples with added phosphates compared with the control. The results of the in vitro experiment confirmed that the added phosphates stimulate the growth of L. pneumophila; growth stimulation could therefore be expected in drinking water distribution systems (DWDS) when phosphates are used as well. The availability of phosphorus in DWDS may be a crucial limiting factor for biofouling control. Consequently, phosphate-based chemicals for drinking water should be avoided or used with prudence, especially in drinking water with high concentrations of other nutrients.

Published: July 2022

Objetivo: Analisar a influência dos níveis operacionais de governança corporativa no gerenciamento de resultado em empresas listadas na B3.
Metodologia: Foi adotada uma pesquisa descritiva com procedimento documental e abordagem quantitativa. A amostra foi composta de 207 empresas listadas na B3 que estão classificadas nos níveis operacionais de governança corporativa. Os dados foram coletados através da Economática® no período de 2013 a 2018 e, posteriormente, foi empregado o modelo desenvolvido por Kang e Sivaramakrishnan (1995). Para estimar o gerenciamento de resultado foram utilizados os softwares SPSS, LhStat e Excel.
Resultados: Os resultados mostram que no aspecto de gerenciamento de resultado não há uma tendência ou uma linha evolutiva que os segmentos que exigem maiores padrões de governança corporativa, as empresas tenham escolhas contábeis de gerenciar menos resultado, ou, que nos segmentos com menores exigências de governança corporativa, as empresas tenham escolhas contábeis de gerenciar mais resultado. Afinal, os níveis operacionais que possuem os melhores conceitos de governança corporativa não influenciam negativamente na prática de gerenciamento de resultado, bem como, os níveis operacionais que não dispõem dos melhores conceitos, não influenciam positivamente na prática de gerenciamento de resultado.
Contribuições do estudo: O estudo trouxe contribuições para o âmbito corporativo, ao abordar a relevância da governança como mecanismo de transparência na prestação de contas das companhias no aspecto de gerenciamento de resultado. Isso possibilita aos usuários inferirem sobre a qualidade da informação contábil divulgada pela B3. Do mesmo modo, contribuições no âmbito acadêmico ao analisar as escolhas contábeis diretamente das demonstrações contábeis das empresas, ocasionando aproximação da teoria discutida na academia com a realidade das organizações.

Published: July 2022

Objetivo: Analisar a influência do ciclo de vida organizacional no desempenho em Responsabilidade Social Corporativa de empresas brasileiras.
Metodologia: Foram estudadas as organizações que estão listadas na B3 e apresentam informações no banco de dados da CSRHub e do Economatica®, no período de 2014 a 2018. A análise dos dados se deu por meio de estatística descritiva e regressão linear múltipla.
Resultados: Os resultados da pesquisa indicam que o estágio de vida turbulência influencia negativamente as ações de RSC. Enquanto os estágios de nascimento, crescimento, maturidade e declínio não foram estatisticamente significantes. O estágio de turbulência representa um momento difícil para a empresa, marcado pela diminuição de vendas e lucratividade, tal fato pode comprometer os recursos disponíveis para financiar os investimentos em RSC.
Contribuições do estudo: A discursão e resultados do estudo avançam no conhecimento de quais fatores antecedentes, como o ciclo de vida das empresas, são capazes de influenciar o engajamento das empresas em RSC. Além disso, a relação entre RSC e o ciclo de vida ainda é pouco explorada na literatura brasileira, o estudo desse relacionamento pode trazer relevantes contribuições ao apresentar o modo que as empresas se comportam diante de restrições de recursos.

Published: July 2022

Objetivo: Este estudo examina a relação entre a estrutura de composição dos gastos nos governos municipais do Brasil e o desenvolvimento humano local no período de 2005 a 2016.
Metodologia: Foi utilizado um teste de hipótese para analisar a relação entre os gastos públicos nos municípios, que foram categorizados de acordo com seus Índices de Gastos (IG) e o Índice Firjan de Desenvolvimento Municipal (IFDM), proxy utilizada para o desenvolvimento humano, baseado no conceito proposto por Sen (1999). Para tanto, foram utilizados dados de todos os 5.570 municípios brasileiros, tratados em forma agregada com a utilização de análise em Painel de Dados e com Regressão Quantílica para abordar de maneira mais abrangente a heterogeneidade dos municípios.
Resultados: Os resultados permitem inferir que para a amostra estudada as mudanças na composição do gasto público não produziram uma melhora significativa no bem-estar da população. Evidencia-se ainda que apesar da manutenção das políticas de cunho social por forte regulação do governo central, os gastos, ainda que crescentes nestas áreas, não vêm produzindo os efeitos desejados na melhoria dos indicadores de bem-estar da população.
Contribuições do Estudo: Esta pesquisa contribui para a academia e a sociedade, pois evidencia que, para que os municípios brasileiros deem passos efetivos rumo ao crescimento e aos indicadores de desenvolvimento humano sustentável de forma mais incisiva, a hegemonização da política de gastos públicos requer ajustes. Esses ajustes poderiam levar em consideração as condições idiossincráticas das diferentes etapas do desenvolvimento humano nos municípios.

Authors: Miranda Claudio de Souza , Lima João Paulo Resende de , Marques Mariana Titoto , Pontes Guilherme Luiz Bertoni 
Published: July 2022

Objetivo: O presente estudo visa apresentar um panorama do perfil dos profissionais de perícia contábil no Brasil e de suas atividades.
Metodologia: Foi desenvolvida uma pesquisa de levantamento (survey) com 556 peritos cujos dados foram obtidos por meio do Cadastro Nacional de Peritos (CNPC), de todas regiões do Brasil. A pesquisa teve enfoque quali-quanti, ao analisar os dados do questionário, bem como as declarações efetudas pelos profissionais.
Resultados: O perito contador brasileiro atua, principalmente de forma individual principalmente na esfera judicial, e de forma concentrada nas áreas Financeira, Contábil e Trabalhista. Mais da metade dos profissionais, não tem a perícia como sua atividade profissional principal, e esta é a principal fatia de profissionais que não está satisfeita com os rendimentos que a atividade proporciona. A atuação profissional se da principalmente por meio perícias judiciais e de apuração de cálculos, principalmente em perícias financeiras, contábeis e trabalhistas. Entre os principais problemas enfrentados pelos peritos está a falta de apoio dos conselhos de classe para o desenvolvimento e defesa da atividade e a dificuldade de compreensão do processo de nomeação dos peritos, que não foi resolvida com a implantação do CNPC. Os peritos, de maneira geral, acreditam que a atividade é pouco valorizada nas universidades, e que os estudantes aprendem pouco sobre ela no curso de graduação.
Contribuições do estudo: Os resultados contribuem para a literatura visto não haver estudos que avaliem de forma ampla a profissão de perito contador no Brasil, tanto no contexto de seu perfil quanto de suas atividades. E no que se refere ao aspecto prático, os dados do estudo fornecem subsídios para que órgãos de classe, associações e o sistema judiciário possam melhorar aspectos do trabalho e da valorização do períto no Brasil.
Overconfidence and audit fees: does the fiscal council influence this relationship?
Authors: Santana Júnior Jorge Luiz De , Sena Thiago Rios 
Published: July 2022

Purpose: This study aims to investigate the role of fiscal council as a mechanism capable of changing the manager's ability to influence audit fees.
Methodology: 231 observations of publicly-held companies that traded their shares on [B]³ in 2017 were analyzed. To investigate the relationship object of this study, an analysis was performed using multiple linear regression with the OLS estimator.
Results: In the analyzed sample, it was identified that managers' overconfidence increases audit costs, which is consistent with the argument that managers' overconfidence can increase the risk of material error. However, possibly due to characteristics of the emerging environment or different levels of efficiency of the fiscal council, it was not possible to confirm the hypothesis that the fiscal council exerts a significant influence on the relationship between manager overconfidence and audit fees.
Study Contributions: In the empirical field, this research provides subsidies for investors and regulators regarding the role of governance mechanisms - more specifically the fiscal council - in the relationship between the auditor and the client. From a theoretical perspective, the accounting literature is added to fill in the existing gap about the consequences of behavioral biases of managers on the audit fees under the moderation of the supervisory board.
Functional and Toxicological Evaluation of MAA-41: A Novel Rationally Designed
Antimicrobial Peptide Using Hybridization and Modification Methods from LL-37
and BMAP-28
Authors: Masadeh Majed , Ayyad Afnan , Haddad Razan , Alsaggar Mohammad , Alzoubi Karem , Alrabadi Nasr 
Published: July 2022

Background:
Managing bacterial infections caused by multidrug-resistant (MDR) and biofilmforming
bacteria is a global health concern. Therefore, enormous efforts were directed toward finding potential
alternative antimicrobial agents, such as antimicrobial peptides (AMPs).

Aim:
We aimed to synthesize a novel modified hybrid peptide designed from natural parents’ peptides with enhanced
activity and reduced toxicity profile.

Method:
The MAA-41 revealed a broad-spectrum activity against Gram-positive and Gram-negative bacteria,
including standard and MDR bacterial strains. The concentration against planktonic cells ranged between 10
and 20 μM, with higher potency against Gram-negative bacteria. The MAA-41 displayed potent activity in
eradicating biofilm-forming cells, and the MBECs were equal to the MIC values reported for planktonic cells.
This new peptide exhibited reduced toxicity profiles against erythrocyte cells but not against Vero cells. Combining
MAA-41 peptides with conventional antibiotics improved the antimicrobial activity of the combined
agents. Either synergistic or additive effects were shown as a significant decrease in MIC to 0.25 μM.

Results:
The MAA-41 revealed a broad-spectrum activity against Gram-positive and Gram-negative bacteria,
including standard and MDR bacterial strains. The concentration against planktonic cells ranged between 10

MAA-41 peptides with conventional antibiotics improved the antimicrobial activity of the combined
agents. Either synergistic or additive effects were shown as a significant decrease in MIC to 0.25 μM.

Conclusion:
This study proposes the validity of a novel peptide (MAA-41) with enhanced antimicrobial activity
and reduced toxicity, especially when used as conventional antibiotic combinations.
Genome-Wide Screening of Differentially Expressed Genes and their
Potential Associations with Aging Dental Pulp Stem Cells
Authors: Ma Xiaocao , Liu Hongchen , Zheng Ying , Dai Yawen , Lingling E. , Zhang Rong , Zhang Shuo 
Published: July 2022

Background:
Dental pulp stem cells (DPSCs) refer to a type of stem cells which is characterized by great differentiation potential and is easy to obtain. DPSCs are able to be employed for treating immune diseases and tissue regeneration. However, the differentiation ability exhibited by aging DPSCs is reduced, thereby limiting the application. As speculated by the microarray analysis, different expression of miRNAs might be involved in DPSC senescence, whereas comprehensive transcriptome level detection has been rare.

Objective and Methods:
To gain insights into the molecular mechanisms involved, RNA-seq, pathway enrichment and Gene Ontology Analysis were conducted on aging and young DPSCs.

Results:
In this study, the differences in lncRNA and mRNA expressions of the aging and young DPSCs were demonstrated, and the vital factors and the relevant pathways were speculated. On the whole, 18950 mRNAs and 21854 lncRNAs were detected, among which 14 mRNAs and 7 lncRNAs were differentially expressed. Furthermore, hsa-miR-6724-5p may be a vital node in the aging process of DPSCs, and its target genes was involved in the dopaminergic synapse.

Conclusion:
In brief, the aging of DPSCs was significantly dependent of different expressed genes (DEGs) which is related to dopaminergic synapse. However, the specific function and internal relationship of the DEGs should be verified in depth.
