Feminismo crítico: interseccionalidade como ferramenta para "lugar de fala" ou a "esfera pública"?
Authors: de Sousa Moura Gabriela , Melo Franco de Moraes Bahia Alexandre Gustavo , Garcia Luiz Carlos
Published: July 2024

Pensar a opressão é sempre tarefa árdua, principalmente quando tal análise se dá em espacializações onde cada indivíduo pode ser atravessado por diversos fatores sociais que isoladamente já possuem o condão de gerar situações de subalternização e sujeição social. Destacar os atores sociais a partir da condição de legitimidade para falar, emerge como um problema a ser analisado aprofundadamente. Assim, a problematização a partir da ferramenta da interseccionalidade como lente capaz de jogar luzes sobre trombos de marginalização social, e trazer para o texto os conceitos de “lugar de fala”, que tem se desgarrado nos debates em geral de sua condição de elemento da Análise do Discurso e de “esfera pública” como espaços que incluem todos como participantes possíveis na qualidade de agentes do discurso, pode fornecer direções para os processos socialmente emancipatórios. Uma compreensão teoricamente sustentável dos elementos como “interseccionalidade”, “lugar de fala” e “esfera pública”, não podem se limitar à uma analítica conceitual formal, mas demanda a assimilação da expansão de seus efeitos pragmáticos também para que as lutas concretas tenham efetividade no contexto democrático. Esse é o pano de fundo da reflexão em que o trabalho opera e se propõe como uma contribuição para um feminismo crítico.

Published: July 2024

Introduction:

Hematological parameters are crucial factors in disease severity and chronic condition pathogenesis. We aimed to evaluate the hematological factors
in different severity stages of COVID-19 at different time intervals.

Methods:

Serum samples were collected from 470 patients (235 men and 235 women)
with a confirmed RT-qPCR COVID-19 test exhibiting moderate, severe, and critical
symptoms based on WHO criteria. Samples were collected at three-time intervals, including the first: the 1st days of infection, 2nd: the one month after, and 3rd: the three
months after disease onset. Total WBC, neutrophil, lymphocyte, monocyte, eosinophil,
RBC counting, Hb, HCT, MCV, MCH, MCHC, hsCRP levels, G6PD deficiency, and hemoglobinopathies were determined in all patients.

Results:

Total WBC, neutrophil, lymphocyte, platelet, RBC counting, Hb, HCT, MCV,
MCH, and hsCRP levels were significantly changed with different disease severity
(p<0.0001). Also, there were significant differences between different time intervals for
WBC and RBC parameters (p<0.0001) except for monocytes and eosinophils. At all
time intervals, there are significant changes in levels of hematological and hsCRP based
on gender. Moreover, a significant correlation was observed between disease severity,
age, and BMI (p<0.0001).

Conclusion:

Significant differences in hematological parameter and inflammatory parameter levels based on disease severity, time intervals, and gender revealed the importance of evaluating these factors in the management of infectious diseases, such as
COVID-19, in patients during and post-disease times.

Studies
Authors: Abazari Omid , Dayati Parisa , Shahidi Maryamsadat , ZavarReza Javad , Rahmanian Mehdi , Naghib Seyed Morteza
Published: July 2024

Background:

Most patients with non-muscle invasive bladder cancer (NMIBC)
have a high direction for recurrence and disease progression, which remains a
significant unresolved challenge in bladder cancer patients. Therefore, a constant search
is necessary for identifying appropriate and reliable biomarkers for early diagnosis of
NMIBC. The current study has aimed to search for valuable diagnostic biomarkers in
the tissue and urine specimens of NMIBC patients.

Methods:

The changes of twelve candidate mRNAs in a screening phase (40 tissue samples
of NMIBC patients and their corresponding 40 urine specimens) and a subsequent
independent validation phase (40 urine specimens) were estimated using real-time polymerase
chain reaction (RT-qPCR). The receiver operating characteristic (ROC) analysis
was executed to determine the potential diagnostic values of mRNAs.

Results:

The mRNA levels of seven candidate genes were markedly higher in tissue
specimens relative to their neighboring tissues. Among them, four mRNAs, including
ERBB2, CCND1, MKI67, and MAGEA6, were differentially expressed in urine samples
of NMIBC patients relative to control subjects. Further, the expression of these four
mRNAs was validated in the validation step. Combining these biomarkers showed better
diagnostic performance than single biomarkers in the urine sample for non-invasive
NMIBC detection. The combination of these mRNAs and cytology enhanced the sensitivity
of cytology from 37% to 87%.

Conclusion:

Our findings suggested that a four-mRNA panel may be promising in the
non-invasive diagnosis of NMIBC, which deserves further investigation.

Published: July 2024

Objective:

Proteomic elucidation is an essential step in improving our understanding of
the biological properties of proteins in amyotrophic lateral sclerosis (ALS).

Methods:

Preliminary proteomic analysis was performed on the spinal cord and brain of SOD1
G93A (TG) and wild-type (WT) mice using isobaric tags for relative and absolute quantitation.

Results:

Partial up- and downregulated proteins showing significant differences between TG and
WT mice were identified, of which 105 proteins overlapped with differentially expressed proteins
in both the spinal cord and brain of progression mice. Bioinformatic analyses using Gene Ontology,
a cluster of orthologous groups, and Kyoto Encyclopedia of Genes and Genomes pathway revealed
that the significantly up- and downregulated proteins represented multiple biological functions
closely related to ALS, with 105 overlapping differentially expressed proteins in the spinal
cord and brain at the progression stage of TG mice closely related to 122 pathways. Differentially
expressed proteins involved in a set of molecular functions play essential roles in maintaining neural
cell survival.

Conclusion:

This study provides additional proteomic profiles of TG mice, including potential
overlapping proteins in both the spinal cord and brain that participate in pathogenesis, as well as
novel insights into the up- and downregulation of proteins involved in the pathogenesis of ALS.

Authors: Coskuner-Weber Orkid , Uversky Vladimir N.
Published: July 2024

The phenomenon of Liquid-Liquid Phase Separation (LLPS) serves as a vital mechanism
for the spatial organization of biomolecules, significantly influencing the elementary processes
within the cellular milieu. Intrinsically disordered proteins, or proteins endowed with intrinsically
disordered regions, are pivotal in driving this biophysical process, thereby dictating the formation
of non-membranous cellular compartments. Compelling evidence has linked aberrations in
LLPS to the pathogenesis of various neurodegenerative diseases, underscored by the disordered
proteins’ proclivity to form pathological aggregates. This study meticulously evaluates the arsenal
of contemporary experimental and computational methodologies dedicated to the examination of
intrinsically disordered proteins within the context of LLPS. Through a discerning discourse on
the capabilities and constraints of these investigative techniques, we unravel the intricate contributions
of these ubiquitous proteins to LLPS and neurodegeneration. Moreover, we project a future
trajectory for the field, contemplating on innovative research tools and their potential to elucidate
the underlying mechanisms of LLPS, with the ultimate goal of fostering new therapeutic avenues
for combating neurodegenerative disorders.

Xenobiotics, Heavy Metals, and Hepatotoxic Agents: A Comprehensive
Review
Authors: Gangawat Rohit , Parashar Ronit , Yadav Ritu Kamal
Published: July 2024

Liver disease, responsible for two million annual deaths, causes Chronic Liver Disease
(CLD) and cirrhosis, causing roughly a million deaths yearly. Treatment options for liver injury induced by hepatotoxicity vary, including medication (N-acetylcysteine, corticosteroids, and ursodeoxycholic acid), lifestyle changes, and sometimes liver transplant. However, effectiveness
varies, and some treatments carry risks and side effects, highlighting the need for improved therapeutic approaches. Murraya koenigii (MK) is known for its hepatoprotective, antioxidant, anti-inflammatory, anti-microbial, nephroprotective, hepatoprotective, gastroprotective, cardioprotective,
neuroprotective, wound-healing, anti-cancerous and immunomodulatory effects, etc. This review
highlights the effectiveness of MK against liver damage induced by heavy metals, drug abuse,
xenobiotics, etc.

A comprehensive search across multiple databases like PubMed, Google Scholar, and others for articles on various hepatotoxicants and hepatoprotective activity of MK was conducted. The researchers applied specific search terms and limits, resulting in 149 eligible articles for final analysis, meeting predetermined inclusion criteria and excluding irrelevant studies.

According to the available literature, the phytochemical components of MK, such as flavonoids,
tannins, and alkaloids present in various extracts, play a crucial role in reversing the hepatotoxic
effects by modifying oxidative and ER stresses, re-establishing the hepatic biochemical markers
and enzymes involved in metabolism denoting ameliorative activity, and controlling the expression of pro-inflammatory cytokines.
To conclude, this review highlights that MK has great potential as a natural hepatoprotective
agent, providing a versatile defense against a range of injuries caused by heavy metals, xenobiotics, and common hepatotoxic agents.

Authors: Meng Li , Zhang Jidong , Chen Cheng , Dai Shihao , Li Qiong , Xiang Kun
Published: July 2024

Introduction:

The development of cost-effective and efficient catalysts plays a pivotal
role in the realization of hydrogen production through electrochemical water splitting.

Methods:

In this study, two-dimensional NiCo2S4 nanosheets were synthesized using a hydrothermal
method followed by a sulfidation process.

Results:

The resulting materials were thoroughly characterized to understand their morphology
and structure. The findings indicate that the NiCo2S4 nanosheets exhibit exceptional electrical
conductivity and a high density of pores, which facilitate electrolyte infiltration and interfacial
charge transfer during electrochemical reactions. Furthermore, the incorporation of S2− modulates
the electronic structure of metal ions, reducing the oxidation potential of metal sites and
promoting the surface reconstruction of the electrode to form active species. Electrochemical
tests conducted in a 1 M KOH solution using the synthesized catalyst as the working electrode
demonstrate an overpotential of merely 280 mV and 300 mV at a current density of 20 mA cm−2
and 40 mA cm-2, respectively, which are much lower than those of NiCo-LDH electrodes (360
mV and 410 mV).

Conclusion:

Furthermore, the NiCo2S4 electrode delivers a remarkably low Tafel slope of 47.9
mV dec−1. This investigation presents a novel approach to the development of efficient transition
metal-based electrocatalysts.
Inflammatory Markers and Ischemic Stroke: Insights and Implications
Authors: Dhaka Arun , Mehta Geetika , Tripathi Rashmi , Sachdeva Monika
Published: July 2024

Cerebral ischemia stands as a significant global cause of both mortality and morbidity
among adults, ranking second in mortality rates. Neuroinflammation, a dynamic and intricate process,
emerges rapidly after ischemia onset and persists for several days. This cascade begins with the activation of microglia and astrocytes, alongside immune cell infiltration, triggering the release of cytokines and initiating an inflammatory response within the brain. These events ultimately contribute to
secondary brain injury, potentially expanding the area of damage beyond the initial affected region.
This sustained inflammatory state contributes to blood-brain barrier disruption and cerebral edema,
exacerbating neuronal damage and impeding neuroplasticity, ultimately worsening neurological deficits. However, the response of inflammation during ischemia is twofold, potentially offering benefits
by clearing cellular debris and facilitating tissue regeneration. This review aims to dissect the roles
of both novel and established pro-inflammatory and anti-inflammatory mediators in cerebral ischemia, offering critical insights for the development of effective therapeutic, diagnostic, and prognostic
strategies.
Salvianolic Acid B Accelerates Osteoporotic Fracture Healing via LncRNA-MALAT1/miR-155-5p/HIF1A Axis
Authors: Gao Zhao , Li Ying , Zhang Yage , Xu Liangliang , Sun Yuxin
Published: July 2024

Background:

Osteoporotic fracture is a pathological fracture secondary to osteoporosis,
causing disabilities and a heavy burden to the patients. In the previous study, we found that salvianolic
acid B (SalB) promoted the osteogenesis of Mesenchymal Stem Cells (MSCs).

Objective:

This study aimed to explore the role of SalB in osteoporotic fracture healing, as well as
the potential molecular mechanism.

Methods:

Human bone marrow mesenchymal stem cells (hMSCs) were treated with SalB or PBS
in vitro, and an osteoporotic fracture model in Sprague-Dawley (SD) rats was established successfully.
SalB or PBS was locally injected at the fracture. Eight weeks later, microCT was used to
compare the healing of osteoporotic fractures with or without SalB. The relative expressions of
mRNAs were measured by qRT-PCR. Bioinformatics analysis, RT-PCR, and dual luciferase reporter
assay were utilized to detect the interrelation of genes. Immunohistochemistry staining was
used to test expressions of proteins.

Results:

In the present study, we found that SalB significantly increased the level of lncRNA--
MALAT1 in a dose-dependent manner. Additionally, silencing lncRNA-MALAT1 inhibited the
expressions of osteogenesis-related marker genes and abolished the effect of SalB on osteogenesis.
Also, we found that lncRNA-MALAT1 sponged miR-155-5p, and miR-155-5p directly targeted
HIF-1α. Using the osteoporotic fracture healing model, our result demonstrated that local administration
of SalB could promote both bone and type H vessel formation in the calluses. The mechanical
test further showed that SalB could improve the mechanical properties of fractured femurs.

Conclusion:

Taken together, our study reported that SalB could promote osteogenesis and type H
vessel formation to accelerate osteoporotic fracture healing through the lncRNA--
MALAT1/miR-155-5p/HIF-1α axis.
A Toluene-induced Infundibulo-neurohypophysitis: A New Cause of
Hypophysitis Secondary to Toxic Exposure
Authors: Costanza Flavia , Giampietro Antonella , Tartaglione Tommaso , Angelini Flavia , Gaudino Simona , De Marinis Laura , Pontecorvi Alfredo , Chiloiro Sabrina , Bianchi Antonio
Published: July 2024

Background:

Hypophysitis is a rare inflammatory disorder of the pituitary gland.
Symptoms and signs of hypophysitis can be various, and its recognition may be challenging.
Arginine vasopressin deficiency (AVP-D) due to exposure to a variety of drugs and toxic substances
is rare, but some cases have been reported. Only 2 cases of AVP-D following toxic exposure
to toluene, an aromatic hydrocarbon, have been reported in the literature. To our
knowledge, our case represents the first description of an infundibulo neurohypophysitis (INH),
manifested with AVP-D, secondary to inhalation of toluene.

Case Report:

A 59-year-old man with an unremarkable medical history was referred to our department
for headache, polyuria, and polydipsia after the inhalation of spray film containing
toluene. The blood tests revealed a hyperosmolar plasma hypernatremia with normal kidney
function. A desmopressin test was performed, with an improvement in water balances, blood
electrolytes, and diuresis contraction. A pituitary MRI detected the absence of a normal hyperintense
signal of the neuro-pituitary in the T1-weighted images. In consideration of the clinical
signs and radiological imaging suggestive of INH, a therapy with desmopressin and corticosteroids
was instituted, with gradual improvement of polyuria and resolution of the radiological
features of INH.

Conclusion:

The exceptional finding of INH, manifested with AVP-D, following toluene inhalation
could represent a new secondary cause of hypophysitis. The possibility that drugs or toxic
substances never reported before could induce INH should not be excluded since the study on
hypophysitis is relatively recent but emerging, predictably destined to increase exponentially in
the coming years.

Published: July 2024

Background

Nile tilapia (Oreochromis niloticus) is a promising fish species for fish farming development in the Republic of Kazakhstan. It exemplifies a balanced and fast-growing source of flesh for future food production. In this context, optimising breeding methods is crucial for a high flesh yield and a safe product. The study delves into the potential of the Enterocol drug in enhancing Nile tilapia breeding, focusing on assessing muscle state and blood parameters.

Objects

Two groups of fish were utilized, with 20 specimens in each group. One set was the control group, and the other was the experimental group. The single difference between the fish groups was the Enterocol consumption by the experimental specimens, which were given an E. coli 64G strain concentration of 108 CFU in mL and a 5% daily dose of fish body weight three times daily for two months.

Methods

Blood parameters were analysed to assess the health of the fish groups. Subsequently, classical pathological methods were employed, such as macroscopic and microscopic assessments of each group's fish material. A histological analysis was also performed to assess the condition of the muscles.

Results

Examining the experimental group's muscles revealed a significant average increase in fish mass and 6.74% total body weight growth. Moreover, the total thickness of the muscle layer decreased as villi height increased, indicating a clear fibre structure. Haematological analysis unveiled elevated levels of haemoglobin, erythrocytes, leucocytes, and total protein in the experimental fish group, indicating improved health. These findings underscore the potential of the Enterocol drug in enhancing fish health and productivity.

Conclusion

Based on the results, it can be concluded that using Enterocol in fish breeding plants can effectively enhance flesh quality and safety, providing a secure and reliable solution for the aquaculture industry.
The Efficacy of Bedside Chest Ultrasound in the Detection of Traumatic Pneumothorax
Authors: Ahmed Saja Ali , Abdul-Qader Shaymaa Khalid , Shakir Nabaa Aswad
Published: July 2024

Background

Chest X-rays have long been used to diagnose pneumothorax. In trauma patients, chest ultrasonography combined with chest CT may be a safer, faster, and more accurate approach. This could lead to better and quicker management of traumatic pneumothorax, as well as enhanced patient safety and clinical results.

Aim

The purpose of this study was to assess the efficacy and utility of bedside US chest in identifying traumatic pneumothorax and also its capacity to estimate the extent of the lesion in comparison to the gold standard modality chest computed tomography.

Methods

This was an observational cross-sectional study of 160 patients with traumatic pneumothorax. This sample was collected from all chest trauma patients admitted to Al-Kindy Teaching Hospital in Baghdad-Iraq between November 2021 and September 2022. Such patients were to have a bedside chest US and chest CT scan performed by a skilled radiologist to detect lung point signs and lung sliding, which would be used to determine the patient's pneumothorax status.

Results

According to the study's findings, about 77.5% of the patients evaluated were men. Furthermore, 40.6% of patients experienced blunt trauma. Chest ultrasound revealed positive pneumothorax in 50 cases (31.2%), while positive pneumothorax was confirmed by computed tomography in 53 cases (33.1%) with no significance in the detection of pneumothorax between the two imaging modalities p-value(0.719). Comparably, there was no significant difference in estimating the size of a pneumothorax between the two modalities (p-value = 0.547). Chest ultrasound diagnostic accuracy showed a sensitivity of approximately 92.45%, specificity of 99.07%, and diagnostic accuracy of 96.88%.

Conclusion

Our findings indicated that chest ultrasound might be a valuable rapid diagnostic tool for traumatic pneumothorax in the emergency department in addition to diagnosis. It eliminates the need to transport patients for a CT chest scan.

Introduction

An in-depth understanding of the ground subsurface is crucial for foundation design and excavation works and for avoiding potential hazards during land development. In this regard, the ground rippability and weathering grades are some of the ground information needed. While geotechnical works are preferred, their limited horizontal coverage and high cost are often constraints that limit their use.

Aims

To counter this, a geophysical survey is employed for its wider area coverage and cost-efficiency. Therefore, this study used the seismic refraction method to assess the rippability and weathering grades in a sedimentary rock geological setting (interbedded sandstone, siltstone, and shale) as a preliminary ground assessment.

Methods

A seismic refraction survey was carried out using Aktiebolaget Elektrisk Malmletning (ABEM) Terraloc Pro 2, where the survey line was 115m long. Rippability was obtained by correlating seismic values with the Caterpillar D10R rippability table. Meanwhile, the weathering grades of the ground were determined by correlating the study area with another study area of a similar geological setting.

Results

Within the 39m penetration depth, three layers can be classified from the ground’s P-wave velocity values and D10R Caterpillar rippability chart, which include rippable, marginal, and non-rippable layers. A break in the continuous ground layers could be seen, causing lower velocity values to be sandwiched between high velocities, which signified the presence of fracture. The weathering grades were also successfully classified from the seismic velocity values.

Conclusion

Using seismic refraction method, this study successfully employed seismic velocity values in determining the rippability and weathering grades of interbedded sedimentary rock without borehole record.

analysis, using modeling and FEM to assess bending stresses and explore strategies to reduce stress
concentrations at the tooth root.

Methods:

The research uses SolidWorks and ANSYS for FEM analysis, focusing on bending
stresses and exploring modifications in gear design using various materials for optimization.

Results:

The analysis shows strategic modifications to the gear's fillet radius and addendum can reduce stress at the tooth root by 38.26%, with stainless steel being the optimal material for enhanced
gear strength.

Conclusion:

The study emphasizes strategic adjustments in fillet radius and addendum to reduce
stress in spur gears, highlighting stainless steel's superior performance for optimized design and enhanced strength.

(38.25 ±12.15) and Covid-negative (33.75±11.28) rate, with a significant p-value (0.031). According
to CFQ, no significant difference (p=0.91) was found between fatigue scores of Covid positive and
negative. However, a significant (p=0. 016) difference was observed between Covid-positive hospitalized
(4.37±0.33) and non-hospitalized (1.98 ±0.22) subjects. QOL scores in different domains,
including QOL General Health (7.18±1.54), physical (20.38±3.51), psychological (46.33±7.05), and
social (9.98±1.94), were all significant (p=0.00) when compared between Covid positives and negatives.

Conclusion:

The study revealed that post-covid survivors experienced fatigue, which imposed limitations
on different aspects of life, which was different from the fatigue of non-affected individuals.

Published: July 2024

The economy of the Arhuaco people, one of the four ancestral communities settled in the Sierra Nevada de Santa Marta, revolves around communal agricultural and livestock production. This is why their primary and secondary education processes prioritize subjects that promote work in the gardens, among which beans, as a traditional and ceremonial food, are prominent. In the context of this growing community, food production requires the development of new teaching tools to disseminate agricultural techniques and practices derived from the intercultural technological innovation processes of agrosavia. Through this educational booklet, the aim is to integrate the worldview of ancestral communities into the management of technical knowledge, in such a way that it guarantees the conservation of their identity and their notion of life territory. The technological hybridization contained in this document—resulting from harmonizing traditional and agroecological thoughts— is presented to the Arhuaco communities and the global scientific community as a fundamental tool for caring for the environment. It also serves to teach the “bonachi” or younger brother to recognize that humans belong to Mother Earth and not the other way around, a call that spiritual leaders make as guardians of the heart of the world.

A economia do povo Arhuaco, um dos quatro povos ancestrais assentados na Serra Nevada de Santa Marta, gira em torno da produção agrícola comunitária, razão pela qual os seus procesos de ensino básico primário e secundário privilegiam disciplinas que promovem o trabalho nas hortas, dentre os quais o feijão como alimento tradicional e cerimonial está presente. No cenário deste povo em crescimento, a produção de alimentos exige o desenvolvimento de novas ferramentas didáticas que divulguem técnicas e práticas agrícolas derivadas dos processos de inovação tecnológica intercultural da AGROSAVIA. Através desta cartilha didática busca-se integrar a cosmovisão dos povos ancestrais na gestão do conhecimento técnico, de forma que garanta a conservação de sua identidade e de sua noção de território de vida. A hibridização tecnológica contida nesse documento – resultado da harmonização dos pensamentos tradicionais e agroecológicos – é apresentada as comunidades arhuacas e científicas globais, como uma ferramenta fundamental para o cuidado do ambiente. Também para ensinar o “bonachi” ou irmão mais novo (não arhuaco) a reconhecer que o ser humano pertence à Mãe Terra e não o contrário, convocação que fazem os líderes espirituais como guardiões do coração do mundo.

Published: July 2024

This study aims to contribute to the improvement and revitalization of purchased rental housing by comparing perceptions between consumers and providers. Housing providers perceive 'external factors' (external noise and odor), 'administrative factors' (completeness of defect repair, ease of receiving defect repair, and connections and support from welfare services), and 'social factors' (opportunities to participate in neighborhood social gatherings) as relatively less important than tenants. Therefore, it seems that housing providers need to actively shift their priorities to customize their work in order to improve the housing satisfaction of tenants in purchased rental housing.. The policy implications are as follows: First, the government and the Incheon Metropolitan Government need to improve the system to realize the per-unit support price of purchased rental housing. Second, the significant impact of exterior noise on residents of rental housing requires a paradigm shift from the current policy of focusing on areas where housing is available for purchase. Third, public housing operators should make efforts to keep effective rents below a certain level, such as flexibly adjusting the conversion rate between security deposits and monthly rents to ensure housing stability. Fourth, it is possible to improve residents' housing satisfaction by improving 'external factors' that public housing operators can control. Fifth, iH needs to improve its management system, which is currently categorized into two regions based on the volume of goods per region, to one that can be visited once a week. Finally, iH's residential welfare service program needs to be improved, as it is mostly conducted in apartment complexes based on convenience and efficiency.

Modern agriculture faces a number of challenges, including climate change, resource constraints and the need to increase productivity. In this context, the assessment of quantitative parameters of crop growth by technical means during the growing season becomes particularly relevant. The scientific approach to this problem is becoming a key tool for optimizing production and ensuring food security, sustainable development of forest ecosystems. (Research purpose) To substantiate the relevance of monitoring crops and undergrowth during artificial reforestation during the vegetative period. (Materials and methods) Video monitoring of agricultural crops, automated segment recognition, geospatial data, literature review, statistical analysis were used. (Results and discussion) The statistics and problems of existing measures for monitoring coniferous undergrowth after reforestation measures were analyzed. The methods of using video monitoring of agricultural crops, in particular, for analyzing the yield of corn shoots, were considered. The use of a video monitoring system to control the care of coniferous undergrowth in the first five years after reforestation was substantiated. Key limitations and difficulties were cited, including high labor costs, insufficient monitoring, lack of systematic approach, limited human labor and low speed and accuracy of data processing. It has been shown that these factors emphasize the need for innovations in methods of controlling the growth of crops and caring for coniferous young. (Conclusions) It was revealed that the video monitoring system of coniferous undergrowth is one of the solutions to the problems of monitoring the condition of forest areas. It was determined that it allows assessing the quality of planting work, determining the growth and health indicators of seedlings, monitoring the environment by indirect signs and, due to a high level of digitalization and automation, responding quickly to violations. It was stated that the assessment of the parameters of crop growth in real time with the use of technical solutions makes it possible to identify problems such as diseases and parasites at an early stage, which will improve the possibilities for their prevention.

Milk production industrial development has led to automated milking technologies. By using of the robot-milker it targeted cows’ selection in the herd according to the morphological contributing and functional characteristics of the udder, that ultimately stimulates milk production increasing. At the same time, robotic equipment use cows’ selection in accordance to stricter selection parameters requires for cows in terms of udder shape and nipple length on dairy farms. The purpose of the research is cows suitability parameters’ study for robot milking and the influence of selection parameters for milking suitability for robotic milking machines for milk production determining. The research was conducted on the basis of data obtained due to 2017-2022 on Kaluga region’s farm by robotic milking machines from Lely (Netherlands) using, the number of cows in average is 126 heads. Studied indicators: milk yield for 305 days of lactation, udder shape, nipples’ shape and size, udder attachment, udder capacity, of udder rear development uniformity, milk flow intensity. As a result of the study, it was found that cows’ milking on a robotic installation contributed to the cows’ selection of with a tubshaped udder (up to 52,3% of the total livestock), with evenly developed udder shares, with a milk yield rate of more than as 2,34 kg/min, as well as milk quality in terms of bacterial contamination and the number of somatic cells improving. On average, the milk yield increase in over 305 days of lactation during the study period was 18,7%. At the same time, the cows selection for milk production, taking into account the indicators determinating on a robotic installation, can be carried out at a higher level with a more cows’ rigid arrangement that do not meet the requirements of robotic milking.
