Afterwards, the responses received from the participants were divided into specific themes. As a result of the research, it was concluded that Kadama Women's Cooperative conducted many studies on women's employment, nearly 1000 women took courses in the cooperative, the products produced by women at their homes or in the cooperative were sold and marketed via cooperative, and social and psychological support was provided to women within the cooperative.
Communication Dynamics of Women in Microfinance Projects as a Model for Women Empowerment
Authors: Vallado Maybel Fernandez
Published: October 2023

This chapter discusses the communication dynamics of women involved in microfinance projects that contribute to the success or failure of the projects in three cases. Specifically, the study (1) identifies the factors that lead to the success or failure of these projects, (2) identifies the MED (micro-enterprise development) lending methodology used in each case by presenting the key characteristics of the three cases, and (3) presents the communication dynamics of women involved in microfinance projects in the context of culture as a model for women empowerment. Using the paradigm model of the grounded theory approach to social science research, the study shows the relationship between and among different variables, namely: origin, development initiative, situation, intervening variables, intervention strategies, and outcomes. The communication dynamics model for women empowerment presented shows how the factors of success and failure lead to empowerment or no empowerment. There is also no empowerment when conditions are oppressive or too lenient.

Published: October 2023

Several strategies have been put forth to efficiently assign the accessible cloud nodes to the client's request and the goal is to improve the cloud's overall performance while also giving users better services and a higher level of customer happiness. An extensive investigation and analysis are done into the idea of using a load balancing method with active monitoring as well as the modification of such an algorithm. There are several ways to accomplish this. The results of the study suggest that when adopting a load balancing method with active monitoring methodology in a cloud computing environment, a more effective active monitoring load balancing method should be used. The load balancing technique gets increasingly challenging as a virtual machine's demand increases. The authors were able to improve throughput while also streamlining the load balancing procedure by using a buffer. Using this information as a foundation, the authors enhanced the load balancing method with active monitoring technique to take into account the growing demand of a virtual machine.

Authors: Subbiah Priyanga , Nagappan Krishnaraj , Bellam Kiran , Thandapani Preethiya
Published: October 2023

Successful cloud computing (CC) lets businesses and people outsource data processing, storage, and access. CC has numerous advantages but new privacy and security risks. Data owners lose control over their data at external providers, making it subject to misuse, distribution, and access. The current data security method involves encryption. Encryption increases computing complexity, especially when data is dispersed throughout several CSP servers. Simple secrecy technologies include encryption and fragmentation. HSSOA-FEW is a hybrid sparrow search optimisation method for cloud security employing fragmentation and encryption. HSSOA-FEW holds data on CSP server with minimal encryption. HSSOA-FEW considers security and data storage. HSSOA-FEW also included sparrow search algorithm (SSA) with particle swarm optimisation. Additionally, HSSOA-FEW uses fused encryption and decryption. HSSOA-FEW controls and secures cloud servers. The suggested HSSOA-FEW system is tested extensively to improve performance. The experiments indicated HSSOA-FEW outperformed others.

Authors: Adam Khaled , Field David
Published: October 2023

The heterogeneity of recrystallized subgrains is a substantial parameter which ought to be consider when controlling recrystallization fraction within a microstructure is needed. The statistical descriptor pair-correlation function is employed as stereological reference for reconstructing the nucleation sites spatial distribution within given volumes based on 2D data. The aim of the current study is to implement the 3D reconstructed particles distribution into a Monte Carlo approach to explore the evolution of microstructure in 7xxx Al alloy during homogenization process. Once the stored energy around the coarse particles is consumed recrystallizing grains the recrystallization is fulfilled. The simulated grain structures are qualitatively evolved in manner of the recrystallization of experimental data, and this verify that recrystallization process is mainly controlled by PSN mechanism.
Linearized Models of the Coupled Rotorcraft Flight Dynamics and Acoustics for Real-Time Noise Prediction
Authors: Saetti Umberto , Bugday Batin , Horn Joseph F. , Brentner Kenneth S.
Published: October 2023

This article demonstrates the linearization of the coupled rotorcraft flight dynamics and aeroacoustics to provide realtime acoustic predictions in generalized maneuvering flight. To demonstrate the methodology, the study makes use of a nonlinear simulation model of a generic utility
helicopter (PSUHeloSim) that is coupled with an aeroacoustic solver based on a marching cubes algorithm. A periodic equilibrium of the coupled rotorcraft flight dynamics and acoustics is first found at a desired flight condition using a modified harmonic balance trim solution method. Next,
the nonlinear time-periodic dynamics are linearized about that periodic equilibrium and transformed into an equivalent higher order linear time-invariant system in harmonic decomposition form. Composite aeroacoustic measures are included as an output of this system. To speed up runtime and
make control design tractable, the order of these harmonic decomposition models is reduced via residualization to an 8-state model where the states are representative of the rigid-body dynamics of the aircraft. This 8-state model is shown to provide accurate acoustic response predictions for
small-amplitude pilot inputs and to abate runtime by a factor of approximately 104, thus enabling acoustic predictions in generalized maneuvering flight that are significantly faster than real time. The 8-state model is subsequently used to demonstrate the use of linear system tools for the
dynamic analysis of the coupled rotorcraft flight dynamics and acoustics.
Allopurinol-induced acquired von Willebrand syndrome
Authors: Eirís Juan , Suárez-Terrón Marina , Granados Pablo , Martínez-Campuzano David , Cid Ana Rosa , Haya Saturnino
Published: October 2023

Acquired von Willebrand syndrome (AVWS) is a relatively infrequent but often overlooked finding when testing for von Willebrand factor (VWF) levels in a patient with mucocutaneous bleeding. Known causes include cardiovascular disorders, hematologic and solid tumors, autoimmune disorders, hypothyroidism, and drugs. An incoercible oral bleeding after a two-teeth removal in a patient with a mechanical aortic valve eventually raised suspicion about an AVWS that was confirmed through laboratory testing. Substitution therapy with an exogenous VWF factor was required to control the bleeding. Known causes of AVWS, including Heyde’s syndrome, were ruled out. VWF levels finally normalized two days after suspension of allopurinol, which the patient received for symptomatic hyperuricemia, leading to his complete recovery and early discharge without any other complications. AVWS is an underdiagnosed entity due to a lack of testing. Allopurinol has never been postured before as a possible etiology and should be evaluated when reaching a diagnosis.

Published: October 2023

Controlling the microclimate condition inside a greenhouse is very important to ensure the best indoor conditions for both crop growth and crop production. To this regard, this paper provides the results of a novel approach to study a greenhouse, aiming to define a porous media model simulating the crop presence. As first, an experimental campaign has been carried out to evaluate air temperature and air velocity distributions in a naturally ventilated greenhouse with sweet pepper plants cultivated in pots. Then, the main aspects of energy balance, in terms of mass transfer and heat exchange, and both indoor and outdoor climate conditions have been combined to set up a computational fluid dynamics model. In the model, in order to simulate the crop presence and its effects, an isotropic porous medium following Darcy’s law has been defined based on the physical characteristics of the crops. The results show that the porous medium model could accurately simulate the heat and mass transfer between crops, air, and soil. Moreover, the adoption of this model helps to clarify the mechanism of thermal exchanges between crop and indoor microclimate and allows to assess in more realistic ways the microclimate conditions close to the crops.

Published: October 2023

At present, ginkgo leave are still picked manually. A brush roller ginkgo leaf picker has been designed to improve harvesting efficiency and reduce losses caused by manual failure to pick leaves in time under large-scale planting areas. The ginkgo leaf picker is mainly composed of crawler chassis, gantry frame, brush roller picking parts, and collecting box. The kinematics of the brush roller is analyzed for the picking omission situation. An experimental platform for picking ginkgo biloba leaves was established. Three parameters, namely roller speed, moving speed, and roller inclination, were selected for optimization. Then the maximum net harvest rate and the minimum damage rate were achieved. The orthogonal test showed that when the roller speed was 130 rev/min, the moving speed was 0.25 m/s, and the roller inclination was 32°, the picking effect was the best, the net harvest rate was 93.32%, the damage rate was 1.42%, and the damage degree of the trunks was slight. The experiment proved that the brush-roller ginkgo leaf picker has a good picking effect, which can provide a reference for the optimization design of ginkgo leaf harvesting machinery under the dwarf dense planting mode.

Authors: Spinelli Andrea , Sendín Baquero Pau , Tiralongo Francesco
Published: October 2023

Penaeus aztecus Ives 1891, commonly known as the brown shrimp, is a well-established invasive alien species of Atlantic origin in the Mediterranean Sea. Here we report on the presence of the species in the Balearic Sea, eastern Mediterranean coast of Spain, where seven specimens were caught in 2023 (February, May and July). Our records represent the first from Mediterranean Spanish waters, as well as the westernmost for this species in the whole basin. Furthermore, on the basis of the data collected, we suggest the presence of a well-established population in this part of the basin. We provide a review on the Mediterranean distribution of the species with discussion on possible pathways of introduction and implications for the ecosystem and fisheries.
Antiviral activity of mangiferin from the rhizome of Anemarrhena asphodeloides against herpes simplex virus type 1
Authors: Wang Wen-Da , Chen Gang
Published: October 2023

Objective:

To evaluate the antiviral activity of pure compounds against herpes simplex virus type 1 (HSV-1) from the rhizome of Anemarrhena asphodeloides.

Methods:

Bioassay-guided isolation was conducted to separate the active compound and its chemical structure was elucidated by spectral analysis. In vitro antiviral efficacy of active compound was detected by Cell Counting Kit-8 assay, plaque reduction assay, and fluorescence observation. RT-PCR was used to determine the viral load and the cytokine-related gene expression after HSV-1 infection. In vivo study was also conducted to further determine antiviral efficacy of an active compound against HSV-1.

Results:

An active compound was isolated and elucidated as mangiferin. Mangiferin significantly inhibited the replication of HSV-1 in Vero cells with a half maximal inhibitory concentration (IC50) of 64.0 mg/L. Time-of-addition and time-of-removal assays demonstrated that mangiferin could effectively inhibit the replication of HSV-1 in the early stage (8 h). UL12, UL42, and UL54 gene expression levels of HSV-1 in the 64 mg/L mangiferin-treated group were markedly reduced as compared with the HSV-1 group (P<0.01). Fluorescence observation showed that mangiferin attenuated the mitochondrial damage maintaining ΔΨm induced by HSV-1 in Vero cells. The expression of inflammatory factors TNF-α, IL- 1β, and IL-6 was remarkably increased in the virus-infected group as compared with that in the normal group (P<0.05), the levels of these inflammatory factors dropped after treatment with mangiferin. Mangiferin significantly decreased the viral load and attenuated the HSV-1-induced up-regulation of TNF-α, IL1β, and IL-6. The relative protection rate of HSV-1-infected mice could reach up to 55.5% when the concentration of mangiferin was 4 g/kg.

Conclusions:

Mangiferin exhibits promising antiviral activity against HSV-1 in vitro and in vivo and could be a potential antiviral agent for HSV-1.
Ponatinib and gossypol act in synergy to suppress colorectal cancer cells by modulating apoptosis/autophagy crosstalk and inhibiting the FGF19/FGFR4 axis
Authors: El-Lakkany Naglaa M. , Elkattan Hadeel H. , Elsisi Alaa E.
Published: October 2023

Objective:

To evaluate the efficacy of ponatinib plus gossypol against colorectal cancer HCT-116 and Caco-2 cells.

Methods:

Cells were treated with ponatinib and/or gossypol at increasing concentrations to evaluate synergistic drug interactions by combination index. Cell viability, FGF19/FGFR4, and apoptotic and autophagic cell death were studied.

Results:

Ponatinib (1.25-40 μM) and gossypol (2.5-80 μM) monotherapy inhibited HCT-116 and Caco-2 cell viability in a dose- and time-dependent manner. The combination of ponatinib and gossypol at a ratio of 1 to 2 significantly decreased cell viability (P<0.05), with a > 2- and > 4-fold reduction in IC50, respectively, after 24 h and 48 h, as compared to the IC50 of ponatinib. Lower combined concentrations showed greater synergism (combination index<1) with a higher ponatinib dose reduction index. Moreover, ponatinib plus gossypol induced morphological changes in HCT-116 and Caco-2 cells, increased beclin-1 and caspase-3, and decreased FGF19, FGFR4, Bcl-2 and p-Akt as compared to treatment with drugs alone.

Conclusions:

Gossypol enhances ponatinib's anticancer effects against colorectal cancer cells through antiproliferative, apoptotic, and autophagic mechanisms. This may open the way for the future use of ponatinib at lower doses with gossypol as a potentially safer targeted strategy for colorectal cancer treatment.
Effect of Pranayama as Adjuvant to Medical Treatment on Severity, Frequency, and Duration of Headache in Migraine Patients: An Open-Label Randomized Controlled Trial
Authors: Kaushal Anjana , Padam Anita , Sharma Minoo , Sharma Sudhir
Published: October 2023

Background:

Migraine is the second leading cause of disability worldwide with high rates of dissatisfaction for allopathic treatment among patients. Pranayama is an easy, convenient, and cost-effective method that can supplement existing standard medical treatment of migraine.

Objective:

To study the effect of pranayama as an adjuvant to standard medical treatment of migraine on clinical outcome variables of migraine.

Materials and Methods:

This was a randomized controlled trial conducted on 80 consecutive migraine patients who were diagnosed as per International Classification of Headache Disorders-3 (ICHD-3) criteria and were randomly allocated into two groups, that is, standard medical treatment (SMT) group and standard medical treatment plus pranayama (SMT + P) group. The effect of pranayama on clinical outcome variables of migraine was evaluated by using standardized questionnaires. The data was statistically analyzed using SPSS Statistics 20 software. A P value of ≤0.05 was considered statistically significant.

Results:

Intragroup analysis showed all clinical outcome variables of migraine reduced significantly in the SMT + P group whereas all clinical outcome variables of migraine except the duration of headache episodes reduced significantly in the SMT group. Although statistically non-significant, intergroup analysis demonstrates that reduction in headache severity, duration of headache episodes, and headache impact test-6 (HIT-6) score was more in the SMT + P group whereas reduction in headache frequency and migraine disability assessment (MIDAS) score was more in the SMT group.

Conclusion:

Pranayama supplements the standard medical treatment of migraine by reducing the duration of headache episodes in addition to the reduction in headache severity, headache frequency, HIT-6 scores, and MIDAS scores.
Tofersen: Silver Lining or Hyperbole??
Authors: Chawla Tanushree , Goyal Vinay
Published: October 2023

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder of anterior horn cells with a dismal prognosis. Over a century since its description, we still do not have a cure for this disorder. Edaravone, Riluzole, and combination of phenylbutyrate and taurursodiol are a handful of FDA-approved drugs that only delay the progression of the disease by a few months. Tofersen, an antisense oligonucleotide, in SOD1 related ALS, has joined the bandwagon of FDA-approved drugs for ALS recently. It is a gene therapy that has been found to lower SOD1 concentrations and neurofilament light chain concentrations in blood and CSF, a known biomarker of ALS, leading to the accelerated approval of the drug. Although it did not show any statistically significant clinical improvement. In this article, we discuss the development and approval process of the first gene-based therapy, Tofersen, for ALS.
Pyruvate kinase M in germ cells is essential for sperm motility and male fertility but not spermatogenesis
Authors: Qian Gao-Qing , Wang Xiao-Chen , Zhang Xi , Shen Bin , Liu Qiang
Published: October 2023

Male germ cells employ specific metabolic pathways throughout their developmental stages. In a previous study, we discovered heightened expression of pyruvate kinase M (PKM), a pivotal glycolytic enzyme, in spermatogonia and spermatids. To gain deeper insights into PKM’s roles in spermatogenesis, sperm function, and male fertility, we engineered a conditional-knockout mouse model (Pkm-vKO mice) to selectively disrupt the Pkm gene within germ cells. Despite maintaining regular testicular histology and sperm morphology, the male Pkm-vKO mice were infertility, characterized by significant impairments in sperm motility and adenosine triphosphate (ATP) generation. In addition, Pkm-null spermatozoa exhibited similar deficits in protein tyrosine phosphorylation linked to capacitation, as well as compromised performance in in vitro fertilization experiments. To conclude, PKM’s presence is not obligatory for the entirety of spermatogenesis in male germ cells; however, it emerges as a critical factor influencing sperm motility and overall male fertility.

Authors: Almokri Nour M. , Alsaggaf Doaa H. , Alsulaimani Fahad Faiz , Zawawi Khalid H.
Published: October 2023

Objectives:

We aimed to assess adult Saudi patients’ facial anthropometry and cephalometric characteristics with skeletal Class III malocclusions compared to Class I malocclusion patients.

Materials and Methods:

Our cross-sectional study included a review of the orthodontic records of 108 patients: 54 patients with skeletal Class III malocclusions and 54 patients with skeletal Class I malocclusions, equally distributed between males and females. Using anthropometric landmarks, seven angular and eight linear measurements were recorded and compared between Class III and Class I patients. In addition, we compared three horizontal facial proportions and three horizontal neoclassical canons between the two groups. Finally, we used Student’s t-tests to compare continuous variables and Chi-square tests for categorical variables.

Results:

Class III patients had significantly larger mandibular length, mandibular plane angle, mid- and lower-anterior face height, and posterior face height (P < 0.05) compared to Class I patients. Class III patients had significantly proclined upper incisors, retroclined lower incisors, and an obtuse interincisal angle (P < 0.05). The mouth: nose ratio differed significantly between skeletal Class III and I patients (P = 0.008). The orbital canon was valid in 14.8% of Class I and 9.3% of Class III patients, respectively. The orbitonasal proportion applied only to 31.5% and 20.4% of Class I and III patients, respectively. The naso-oral canon occurred in 18.5% and 1.9% of Class I and III patients, respectively.

Conclusion:

Saudis with Class III skeletal profiles have some distinctive Class III characteristics not observed in most other ethnic groups. The established horizontal facial proportions, neoclassical facial canons, and Class III skeletal profile did not apply to Saudis with skeletal Class I malocclusions, indicating that these proportions and characteristics may not be suitable as references when planning the surgical treatment for these patients.

Authors: Almeida Nathalia Elissa M. , Ormiga Fabiola , Lima Carolina O. , Santos Thais M. P. , Lopes Ricardo T. , Risso Patrícia de Andrade
Published: October 2023

Context:

Excessive dentine wear during postremoval can occur due to the adhesion between the cement and the post.

Aim:

The aim is to evaluate dentine wear and microcrack occurrence following the removal of intraradicular fiberglass posts that were previously cemented with two types of resin cement.

Methods:

Distal roots (n = 38) of lower molars were instrumented, filled, prepared for intraradicular postinstallation, and divided into two groups according to the cement used for the posts: RelyX ARC or RelyX U200. The posts were removed through abrasion using ultrasonic diamond tips, after which the degrees of dentine wear (volume/mm3) and microcrack formation were assessed using microcomputed tomographic imaging.

Statistical Analysis Used:

The Mann–Whitney U (P ≤ 0.05) and Chi-squared tests (P ≤ 0.05) were used.

Results:

After the removal of the posts, no statistically significant difference in root canal volume or microcrack occurrence was observed between the groups (P > 0.05). The procedure produced significant dentine wear regardless of the type of cement used (P < 0.05).

Conclusions:

The removal of fiberglass posts caused extensive dentine wear but did not influence microcrack occurrence. The type of resin cement used did not affect the dentine loss or microcrack appearance that resulted from fiberglass postremoval.

The cystic duct was visualized in 87.3% cases with a mean time of visualization of 32.10 minutes. The hepatic duct was visualized in 28.57% and the hepatic duct-CBD confluence was visualized in 34.28% patients.

Conclusion:

Near infrared imaging based intra-operative cholangiography, using Indocyanine Green dye, during Lap. Cholecystectomy is an easy, useful and inexpensive method of visualizing the biliary ductal anatomy.
Impact of Hydrogen Energy Fractions on Cycle-to-Cycle Variations in Biogas-Fueled Spark Ignition Engine
Authors: Sagar Abhinandan , Kurien Caneon , Mittal Mayank
Published: October 2023

The limitations related to the cost-effectiveness and technological feasibility of upgrading biogas to bio-methane for rural power generation applications have prompted researchers to explore alternative approaches for improving the quality of biogas fuel. This study focuses on evaluating the effect of hydrogen enrichment on combustion characteristics and cycle-to-cycle combustion variations in a single-cylinder spark ignition engine fueled with biogas (60% CH4 and 40% CO2). The engine was run at a constant operating load of 6 Nm, with a compression ratio of 10:1 and an engine speed of 1500 rpm. To establish a baseline for comparison, engine characteristics were initially assessed using pure methane fuel. Subsequently, the share of hydrogen in the biogas fuel mixture was incrementally increased on the volumetric basis from 0% to 30% and experiments were performed to study the effects of these variations on combustion behavior. The statistical approach was adopted for analyzing cycle-to-cycle variations by considering 120 consecutive engine cycles. The results of this study showed that increasing the H2 share from 0% to 30% in an SI engine powered by biogas improved the combustion characteristics (increment in peak in-cylinder pressure; reduction in COVIMEP from 9.9% to 1.7%; improvement in combustion phasing). With the addition of H2, flame propagation speed increased and combustion time decreased. Results indicated that hydrogen enrichment resulted in lower cycle-to-cycle variations (CCVs) of pressure and combustion-related parameters.

Remarks on the geometry of the variety of planes of a cubic fivefold
Authors: Mboro René
Published: October 2023

This note presents some properties of the variety of planes $F_2(X)\subset G(3,7)$ of a cubic $5$-fold $X\subset \mathbb P^6$. A cotangent bundle exact sequence is first derived from the remark made by Iliev and Manivel that $F_2(X)$ sits as a Lagrangian subvariety of the variety of lines of a cubic $4$-fold, which is a hyperplane section of $X$. Using the sequence, the Gauss map of $F_2(X)$ is then proven to be an embedding. The last section is devoted to the relation between the variety of osculating planes of a cubic $4$-fold and the variety of planes of the associated cyclic cubic $5$-fold.

Published: October 2023

Microplastic pollution is a serious problem and harms aquatic ecosystems, especially for organisms that are filter feeders. This research aimed to analyse the concentration of microplastics contained in epibionts attached to green mussels (Perna viridis) in the water of Lae-Lae Island, Makassar. Sampling was conducted using the purposive random sampling method, to obtain 110 green mussels which were divided into three groups of shell length: small (2.42-4.40 cm), medium (4.41-8.01 cm), large (8.02- 14.62 cm) groups. In addition, based on the microplastic content, the epibionts associated with green mussels were also divided into four groups, namely (1) microplastics in green mussels with epibiont attached, (2) microplastic in green mussels without epibiont attached, (3) microplastics in epibiont attached to green mussels, (4) microplastics in green mussels and epibiont. Microplastic particles were observed using a stereo microscope with Image J Software. The result depicted that the microplastics were fibres, fragments, and films with blue as the dominant colour. The size of microplastics ranged from 0.03-4.72 mm. The results showed no significant differences in the concentration of microplastics of epibionts at different green mussel shell lengths (p > 0,05). However, there was a statistically significant difference in the concentration of microplastics in epibionts with their host, green mussels, in which the concentration of microplastics in epibionts was greater than that in green mussels (p > 0.05). This study suggested that the epibionts and the green mussels played a role in reducing microplastic in waters.

Вступ. Проведений семантичний аналіз відповідних джерел інформації щодо проблеми вторинної профілактики захворювань у військовослужбовців дозволяє констатувати, що інформаційні матеріали віддзеркалюють показники їх захворюваності з актуальних патологічних станів, констатують їх негативних вплив на боєздатність військовослужбовців, обґрунтовують необхідність удосконалення заходів профілактичного впливу з використанням підходів пацієнт-орієнтованої медичної допомоги, але не враховують в повному обсязі особливостей їх проведення в умовах воєнного стану. Виходячи з цього, проблему розробки уніфікованої організаційної моделі проведення вторинної профілактики захворювань військовослужбовців, яка б передбачала ефективну взаємодію військових та цивільних медичних закладів в межах єдиного медичного простору за умов дії правового режиму воєнного стану, слід вважати актуальною, що й дозволило визначити мету проведеного дослідження.

Мета дослідження полягає у обґрунтуванні уніфікованої моделі організації проведення вторинної профілактики захворюваності серед військовослужбовців в умовах дії правового режиму воєнного стану, яка передбачає забезпечення ефективної взаємодії військово-медичних закладів з закладами охорони здоров’я МОЗ України в цих умовах.

Матеріали та методи. Дослідження проводилося із використанням класичних соціально-гігієнічних методів: монографічного, семантичного, аналітичного, документального обліку та системного аналізу.  Матеріалами дослідження слугували нормативні документи та інформаційні матеріали з питань профілактики та захворюваності військовослужбовців.

Результати. У статті обґрунтована уніфікована модель організації проведення вторинної профілактики захворюваності серед військовослужбовців в умовах дії правового режиму воєнного стану, яка передбачає забезпечення ефективної взаємодії військово-медичних закладів з закладами охорони здоров’я МОЗ України в цих умовах. Проведено обґрунтування, визначені організаційні підходи та шляхи удосконалення заходів з вторинної профілактики захворюваності військовослужбовців.

Висновки. Доведено, що від якісного проведення вторинної профілактики захворювань залежить забезпечення здоров’я військовослужбовців, які мають значний досвід бойових дій, а, відповідно, сприяють підвищенню боєздатності військових частин і підрозділів. Розроблена уніфікована модель взаємодії військово-медичних закладів з закладами охорони здоров’я МОЗ України в умовах воєнного стану. Впровадження заходів вторинної профілактики сприятиме попередженню загострення хронічних захворювань тим самим зменшуючи функціональне навантаження на військово-медичні заклади, що має актуальне значення в умовах воєнного стану. Слід вважати, що проведення вторинної профілактики військовослужбовців не повинно підміняти заходів первинної профілактики захворювань та травм, з урахування особливостей військової служби в умовах воєнного стану.

Вступ. Досягнення у галузі гіпербаричної медицини і фізіології складають основу систем життєзабезпечення операторів екстремальних видів діяльності (водолази, льотчики, космонавти, тощо). При цьому, використання для дихання в умовах гіпербарії газових сумішей різної комплектації сприяє вивченню нових проявів біологічної відповіді. В цілому, результати дослідження механізмів адаптації людини до дії гіпербаричного середовища мають фундаментальне і практичне значення, особливо, у напрямах забезпечення проникнення людини у «гідрокосмічний» і космічний простір, лікувального застосування гіпербаротерапії і гіпербаричної оксигенації, використання у медицині біологічних властивостей інертних газів.

Метою дослідження було проведення огляду наукових досліджень у галузі гіпербаричної фізіології при вивченні механізмів адаптаційних та дизадаптаційних перебудов в організмі людини, удосконаленні технологій практичного використання властивостей низки інертних газів, газових сумішей і гіпербаричної оксигенації у водолазній справі.

Матеріали і методи. У дослідженні були використані методи семантичного аналізу, бібліографічного дослідження та опису електронних ресурсів.

Результати. У продовж останнього століття освоєння людиною підводного світу стрімко прогресує. Це пов’язано з інтенсифікацією проведення робіт у річкових і шельфових акваторіях, включаючи видобуток корисних копалин, розширення завдань придонного будівництва, зростання актуальності специфічної підводної діяльності збройних сил, аварійно-рятувальних підрозділів, тощо.  Підводне занурення з можливістю водолаза виконувати фахові завдання безпосередньо в умовах підводної гіпербарії потребує постійного удосконалення технологій медичного забезпечення і якості підготовки кваліфікованих фахівців. При цьому, відомо, що обмежені резерви адаптаційної здатності організму людини до комплексного впливу специфічних факторів підводного середовища відіграють лімітуючу роль у реалізації повноцінної комфортності при перебуванні в умовах гіпербарії і підводного середовища. Отже, забезпечення надійності життєдіяльності, працездатності і безпечного перебування людини у гіпербаричних умовах та підводному середовищі залежать від досконалості вивчення механізмів адаптації організму людини до впливу високого барометричного тиску та зміненого дихального середовища, що є основними напрямами досліджень у галузі гіпербаричної фізіології і водолазної медицини.

Висновки. Тематика даного огляду продиктована наявним дефіцитом прицільних наукових досліджень у галузі гіпербаричної фізіології та обмеженим доступом до профільної інформації, що не дозволяє у повному обсязі враховувати навіть вже відомі медико-біологічні ефекти при вивченні механізмів адаптаційних та дизадаптаційних перебудов в організмі, а також удосконалювати технології практичного використання властивостей низки інертних газів, газових сумішей і гіпербаричної оксигенації для потреб медицини.

Мета роботи дослідити особливості поранень при мінно-вибуховій травмі (МВТ) в залежності від відстані до епіцентру вибуху, сили вибуху, типу вибухового пристрою, дії ударної хвилі на цивільних та військових осіб, які знаходяться в умовах російського вторгнення в Україну з 2022 року.

Матеріали і методи. При виконанні роботи використані наступні методи: контент-аналіз, порівняльний аналіз та систематизація дослідженого матеріалу. Проаналізовано 243 примірники висновків експертів судово-медичної експертизи трупів військовослужбовців, доставлених із зони бойових дій та тіл цивільних осіб, що постраждали внаслідок ракетного удару по м. Вінниця в період 2022-2023 р.р. Крім того, частково вивчені матеріали кримінальних впроваджень, що надавалися слідчими при проведенні судово-медичних експертиз, а саме: протоколи огляду місця подій та протоколи допитів свідків, в яких містилися відомості щодо перебування окремих осіб в конкретних місцях під час вибухів. Проведено дослідження наукових публікацій вітчизняних та зарубіжних вчених з використанням баз даних PubMed і Google Scholar за період 2014-2023 р.р.

Результати. Компоненти та складові МВТ залежать від місцезнаходження особи на момент вибуху, сили вибуху, типу вибухового пристрою, дії ударної хвилі, первинних та вторинних елементів ураження, дії високої температури та продуктів вибуху і горіння. Згідно з архівним матеріалом, у більшості осіб мали місце комбіновані (механічні, термічні) ушкодження передньої та задньої поверхні тулуба (85%), переломи кісток (25%), забої та розриви внутрішніх органів (68%), проникаючі та поверхневі осколкові поранення (95%), опіки (64%), відкриті (15%) та закриті черепно-мозкові травми (ЧМТ) (17%).

Висновки. За результатами дослідження тяжкість ушкоджень при мінно-вибуховій травмі залежить від місцезнаходження людини на момент вибуху, типу вибухового пристрою та його сили, а також інших додаткових чинників. Встановлено відмінності ушкоджень при МВТ у цивільних та військових осіб, які пов’язані з наявністю у військових захисного спорядження та підготовки щодо поведінки під час ракетного обстрілу. Аналіз досліджених випадків вказує на низьку залежність між тяжкістю травмувань та відстанню особи до епіцентру вибуху. .Водночас прослідковується чітка закономірність значного зниження тяжкості ушкоджень при знаходженні осіб за умовними перешкодами (стінами, захисними спорудами). Спостерігається залежність від позиції та пози людини (лежачи на землі, напівлежачи, напівсидячи) та тяжкістю ушкоджень під час ракетних обстрілів та вибухів, які вони спричиняють.
Anatomy and Histology of the Male Reproductive System and Sperm Morphology of Leptoglossus Zonatus (Dallas, 1852) (Heteroptera: Coreidae)

Coreidae is a diverse family formed predominantly by plant-sucking bugs, containing about 520 genera, more or less 3,100 species worldwide, and 165 genera in the Neotropical region. The genus Leptoglossus usually undergoes five instars throughout its life and has a worldwide distribution, especially in the Americas. Leptoglossus zonatus is a phytophagous bug that feeds on Poaceae, Leguminosae, Rutaceae and Punicaceae crops, with maize being its primary food source. Data related to aspects of the reproductive system of Heteroptera are essential to understand the biology of most of its representatives, in addition to assisting in the systematics. Thus, the data from this study could provide helpful information for taxonomy and for understanding the relationships of this species, or genus, with other group members. So, we described the morphology of the male reproductive system and spermatozoa of the bedbug L. zonatus. Adult individuals were collected in Viçosa, MG – Brazil and their reproductive systems were processed for light histology. For morphometry of the spermatozoa, these were collected from the seminal vesicles of males, and the Giemsa dye was used to measure the total length and the DAPI dye to measure the nucleus. L. zonatus has a pair of testes and two distinct types of coiled accessory glands. Each testis has a pecten-shaped, like Machtima crucigera and Coreus marginatus and is surrounded by a red-pigmented, highly tracheolated testicular sheath, as seen in other Coreidae. It has seven elongated follicles joined by testicular sheath septa. The cysts are spherical initially and elongate toward the final phase of spermatogenesis, with an average of 850 spermatozoa per cyst (nine cycles of cell division). Spermatogenesis occurs throughout the adult life of this insect, producing sperm thin and elongated that measures an average of 310 µm in length, with a 36 µm nucleus. They are do not form bundles in the seminal vesicles, being transferred to the female freely during copulation. Characteristics such as the number of follicles per testis and sperm production throughout adult life certainly reflect the reproductive success of L. zonatus, and these findings, including sperm morphometry, may help in future research to understand the diversity, taxonomy, and systematics of the genus Leptoglossus, as well as of other Coreidae in the suborder Heteroptera. Keywords: Hemiptera. Pentatomomorpha. Testicular morphology. Sperm development. Accessory glands.

Authors: Riantika Putri Ayu , Pane Nazliyani
Published: October 2023

Tidak dipungkiri bahwa manusia adalah makhluk sosial yang membutuhkan bantuan dari orang lain memenuhi kebutuhan hidupnya. Biarpun begitu banyak masyarakat yang khususnya  beragama Islam enggan bersedekah dan berinfak. Padahal sedekah adalah amal dalam agama Islam yang memberikan pahala tak terbatas dan menjadi sumber investasi amal baik yang tidak pernah berhenti. Dalam ajaran agama Islam selain bersedekah ada alternatif lain untuk manusia saling berbagi salah satunya infak. Tujuan penelitian ini adalah untuk mengetahui keutamaan orang yang bersedekah dan berinfak berdasarkan hadis yang diriwayatkan oleh Imam Bukhari dan Imam Muslim. Dipenilitian ini terdapat dua hadis dalam keutamaan sedekah dan infak yang diriwayatkan oleh Imam Bukhari dan Muslim dimana dalam kedua hadis ini menjelaskan tentang manfaat bersedekah dan infak yang mana salah satunya adalah  sedekah tidak mengurangi harta melainkan akan menambah kemuliaan bagi yang bersedekah dan berinfak. Keutamaan-Keutamaan sedekah dan infak berdasarkan hadis Nabi meliput; pertama, Berinfak tidak akan membuat seseorang menjadi miskin. Kedua, Sedekah tidak mengurangi harta.

Pohon mempunyai fungsi yang sangat penting dalam upaya meredam kenaikan gas rumah kaca penyebab utama pemanasan global dan perubahan iklim. Pohon menyerap karbondioksida yang dihasilkan oleh kegiatan-kegiatan yang dilakukan manusia dan makhluk hidup lainnya. Tercatat pada tahun 2013 Indonesia berada di peringkat ketiga hutan terluas versi data Forest Watch Indonesia (FWI). Maka, tidak heran jika kemudian Indonesia dijuluki Paru-paru Dunia. Tetapi pada perkembangan selanjutnya di tahun 2019 tingkat deforestasi Indonesia masih tinggi sehingga mengundang kekhawatiran global. Salah satu bentuk deforestasi atau penghilangan hutan adalah dengan menebang pohon demi pembukaan lahan baru untuk keperluan industri. Selain itu, data Food and Agriculture Organization (FAO) pada 2019 menjelaskan bahwa setiap harinya, terdapat sekitar 50 hektar hutan Indonesia mengalami kerusakan sejak 2007. Hal ini menjadikan Indonesia sebagai negara yang mengalami kerusakan hutan tercepat.Pada data terbaru di tahun 2021 oleh Kementerian Lingkungan Hidup dan Kehutanan menjelaskan bahwa deforestasi hutan Indonesia cenderung menurun dan stabil, namun di lain sisi terdapat masalah tambahan gas karbon dan produksi emisi yang meningkat sehingga membuat atmosfer bumi panas dan mempercepat terjadinya perubahan iklim.
Permasalahan ini memberikan inspirasi tim pengabdian masyarakat UNIVA Medan melakukan kegiatan pelestarian lingkugan melalui kegiatan pembagian bibit pohon untuk ditanam di perkarangan rumah ataupun lingkungan sekitar, penanaman pohon serta melakukan bimbingan informasi tentang meregulasi diri dalam melestarikan lingkungan untuk mencapai kebahagiaan. Kegiatan ini bertujuan untuk menyadarkan kembali tentang pentingnya kontrol diri dalam melestarikan lingkungan Kota Medan agar semakin asri, bersih dan nyaman bagi penduduknya sehingga harapannya tingkat kebahagiaan individunya pun akan meningkat. Kegiatan dilakukan bersama Persatuan Perempuan Sumatera Utara (Ppesut) dalam penyelenggaraan Acara Peringatan Hari Ibu ke-94 di Ruang Terbuka Halaman Stadion Mini Kampus USU.
