The article presents the results of the study of reference sites with the medicinal plant Chelidonium majus L. in the Kazakh part of the Kungai Alatau. Descriptions of 5 reference sites with typical communities (floristic composition and structure) of different vegetation belts are given. Kungai Alatau is a peculiar and interesting region of the Northern Tien Shan, located at the junction of three botanical-geographical provinces different in their natural features: Central Tianshan-Zaalai, Kashgar-East Tianshan transitional and Dzungar transitional. The study region is of interest as a transboundary territory with the Republic of Kyrgyzstan with a high degree of botanical diversity. Due to its border physical-geographical position, the formation of its flora was influenced by different large botanical-geographical centers (Northern and Western Tien Shan). The species composition of natural complexes of many parts of the ridge has been preserved in a natural state due to its inaccessibility and represents a reference in floristic respect for the whole Northern Tien Shan. The authors of the work conducted cycles of studies on the study and distribution of C. majus on the territory of the Kazakh part of the Kungai Alatau Ridge. Kungai Alatau, which allowed now to obtain more complete data on the existence of populations of the studied species, the peculiarities of their habitat in different plant communities, the identification of the degree of impact of negative factors on the population and the duration of the consequences of the negative impact. It was found that C. majus mainly grows on mountainous southern slopes of the lower and middle belt, among bushes, along the banks of rivers and along the plumes of slopes of gorges.

It is known that long-term storage of cultures with the help of periodic reseeding does not always ensure the stability of morphological, cultural and physiological characteristics. In this regard, the question arises of the need to study the range of variability of individual characters and the influence of the environment on the heterogeneity properties of collection cultures and study their morphophysiological properties. We considered it appropriate to return to the study of the main taxonomically significant phenotypic characters of these yeasts. As a result, it was noted that the culture of Candida sphaerica KM95 does not show natural variability, which would be expressed in the macromorphological heterogeneity of the population: almost all colonies had similar characteristics. The culture of Candida kefyr var. kumis 17 when sieving on a dense medium, a noticeable variability is observed in a number of morphological features. Thus, the population composition is represented by several types of colonies that differ from each other in size, color, shape, structure, etc. In search of cultures that ferment lactose intensively, 25 yeast strains isolated from shubat and assigned to the genus Candida were tested. As a result of a comparative study of enzymatic activity, by examining the ability of different strains to ferment lactose, the most active of them were identified - C. sphaerica 1M and C. sphaerica 3M. According to our observations, the studied cultures are able to ferment maltose after their long-term cultivation on wort agar, however, the ability to grow on a medium with lactose is lost.

Impact of Single vs Combination Anti-Hyperglycemic Drug Therapy on HbA1c Levels: A Cross-Sectional Study
Authors: Diatri Devita , Rakhmawatie Maya Dian
Published: July 2024

Diabetes Mellitus (DM) is a long-term medical condition characterized by increased blood glucose levels caused by abnormalities in the insulin metabolism process. Various types of antihyperglycemic drugs are available, both as single and combination therapy. Recent research shows that single or combination therapy can impact glycemic control differently, especially when looking at changes in HbA1C levels.  This research is descriptive-analytical with a cross-sectional design using medical record data from Type 2 DM patients in the 2022-2023 period.  Data was analyzed using SPSS. In this study, there was a significant relation between single and combination anti-hyperglycemic drug therapy. Bivariate analysis showed that both single and combination therapy were associated with a reduction in HbA1C levels, with a p-value of 0.019. There is a correlation between HbA1C levels and single and combination therapy in type 2 DM patients at the Prolanis Clinic.

Background

Active follow-up of chronic hepatitis C notifications to promote linkage to care is a promising strategy to support elimination.

Aim

This pilot study in Victoria, Australia, explored if the Department of Health could follow-up on hepatitis C cases through their diagnosing clinicians, to assess and support linkage to care and complete data missing from the notification.

Methods

For notifications received between 1 September 2021 and 31 March 2022 of unspecified hepatitis C cases (i.e. acquired > 24 months ago or of unknown duration), contact with diagnosing clinicians was attempted. Data were collected on risk exposures, clinical and demographic characteristics and follow-up care (i.e. HCV RNA test; referral or ascertainment of previous negative testing or treatment history). Reasons for unsuccessful doctor contact and gaps in care provision were investigated. Advice to clinicians on care and resources for clinical support were given on demand.

Results

Of 513 cases where information was sought, this was able to be obtained for 356 (69.4%). Reasons for unsuccessful contact included incomplete contact details or difficulties getting in touch across three attempts, particularly for hospital diagnoses. Among the 356 cases, 307 (86.2%) had received follow-up care. Patient-management resources were requested by 100 of 286 contacted diagnosing clinicians.

Conclusions

Most doctors successfully contacted had provided follow-up care. Missing contact information and the time taken to reach clinicians significantly impeded the feasibility of the intervention. Enhancing system automation, such as integration of laboratory results, could improve completeness of notifications and support further linkage to care where needed.

Analysis Of The Impact Of Changes In The Negative Investment List On The Film Industry In Indonesia
Authors: Hendri
Published: July 2024

This study aims first to understand the implementation of Presidential Regulation Number 44 of 2016 for the film industry in Indonesia and, secondly, to identify and assess the impact of changes in the negative investment list on the film industry in Indonesia. The study utilizes a normative juridical research methodology, combining legal and conceptual approaches. The findings indicate that enforcement of Presidential Regulation Number 44 of 2016 in the Indonesian film industry resulted in the absence of international film companies operating in Indonesia before the regulation was implemented. However, this situation changed after films were removed from the Negative Investment List (DNI) as stipulated in Presidential Regulation Number 44 of 2016, an amendment to Presidential Regulation Number 39 of 2014 regarding categorizing closed and open business sectors with investment requirements. Modifying the negative investment list for the film industry in Indonesia has both positive and negative consequences. On the positive side, it has increased foreign investment, contributing to economic growth. Conversely, local investors need help competing with foreign investors due to financial resource disparities. The implementation of Presidential Regulation No. 44 of 2016 has had a significant impact on the investment landscape. Specifically, there has been an increase in foreign capital investment. However, it is worth noting that the number of Foreign Direct Investment (FDI) projects exceeds that of Domestic Direct Investment (DDI) projects. This difference can be attributed to the inability of domestic investors to compete effectively in the market.

Published: July 2024

Pesquisas sobre a qualidade do ar em ambientes internos começaram a ganhar destaque na década de 1970, especialmente no hemisfério norte, em resposta à crise energética daquela época. Para economizar energia, foram desenvolvidos edifícios “vedados”, projetados para minimizar a troca de ar interno e externo. No entanto, essa abordagem resultou em uma ventilação inadequada, que aumentou significativamente os níveis de poluentes internos. Com o advento da pandemia da COVID-19, em 2020, voltou a` tona a importância da ventilação para reduzir a transmissão do vírus SARS-CoV-2. Ambientes hospitalares tiveram atenção especial nesse período. Esse trabalho buscou avaliar a qualidade do ar em um hospital universitário considerando alguns parâmetros físico-químicos (material particulado (MP), CO2, temperatura e umidade relativa) definidos pela Resolução no. 9 da Anvisa. Os resultados mostraram que, dentre os parâmetros analisados, apenas o CO2 atendeu aos padrões de qualidade do ar. Os demais parâmetros não estavam em concordância com as legislações devido a maior troca interna/externa recomendados pelas agências sanitárias para evitar o acúmulo de vírus e a sua transmissão. Dessa forma, a abertura de portas e janelas para aumentar a ventilação fez com que a qualidade do ar interno e externo fosse similar.

A má´ qualidade do ar em ambientes fechados pode causar muitos danos à saúde. Em se tratando de ambientes internos de universidades, a presença de poluentes pode afetar a concentração e o desempenho dos alunos e profissionais. Este estudo teve como objetivo monitorar os ni´veis de dióxido de carbono (CO2), formaldeído (HCHO), material particulado (MP), fungos, bactérias e também os parâmetros físicos, temperatura e umidade relativa em ambientes internos da PUC-Rio (biblioteca, sala de aula, restaurante universitário e laboratório de pesquisa). Também foi monitorado o ambiente externo para fins de comparação. O monitoramento foi realizado durante os meses de novembro de 2023 e abril de 2024 utilizando sensores de medição em tempo real para os poluentes químicos e coletores ativos para material biológico. Os resultados mostraram a presença de fungos e bactérias e o acúmulo de CO2 nos locais mais densamente ocupados e sugerem que os sistemas de renovação do ar são ineficientes. Algumas medidas foram sugeridas para a melhoria da qualidade do ar nesses ambientes.

Published: July 2024

Fungos são estruturas microscópicas com capacidade de crescimento no formato de filamentos multicelulares, chamados de hifas que dão origem ao mofo. O crescimento do mofo e´ favorecido pelo excesso de umidade, vazamentos ou degradação de materiais, que ocorrem a partir de diversos aspectos estruturais que compõem os ambientes internos. A concentração desses seres vivos e de seus metabólitos é transportada pelo ar em diferentes ambientes como residências, escolas, hospitais, edifícios comerciais, dentre outros espaços “fechados”, e afeta diretamente a qualidade do ar interno, relacionando-se com efeitos respiratórios e outros aspectos na saúde. A reação fisiológica a patógenos, através da inflamação e das respostas imunes inata e adaptativa, também ocorre diante das microtoxinas do mofo. Estas, por sua vez, agem no organismo e provocam uma cascata de eventos inflamatórios e imunes a nível molecular, refletindo sob a forma de doenças e quadros sintomáticos importantes na saúde dos seres vivos, como formas respiratórias, atópicas, emocionais, neurológicas, entre outras. Portanto, a presente revisão narrativa tem o objetivo de discutir evidências científicas sobre os efeitos dos fungos na saúde humana, bem como promover uma base de orientação clínica e geral para medidas preventivas que possam evitar a exposição aos perigosos bioaerosso´is.

This study investigates the relationship between labor use and food security among rural maize farmers in Abuja Metropolis, Nigeria. Using a two-stage sampling procedure, 125 maize farmers were selected from various villages within the study area to participate. A structured questionnaire was employed to gather data, focusing on labor allocation, food security metrics, and socio-economic variables. The collected data were analyzed using descriptive statistics, a food security index, and a probit regression model. Findings indicate that maize farmers in Abuja Metropolis utilize both hired and family labor, with varying implications for household food security. Specifically, higher reliance on family labor tends to enhance food security, whereas increased dependence on hired labor correlates with decreased food security among rural farming households. Based on these findings, the study recommends several interventions to improve food security in the region. These include enhancing access to credit facilities for farming households, promoting agricultural engagement among youth to alleviate dependency on non-agricultural jobs, and advocating for family planning initiatives to manage household size, thereby mitigating food insecurity risks associated with larger families. This research contributes to the understanding of labor dynamics in agricultural settings and offers practical insights for policymakers, governmental agencies, and non-governmental organizations aiming to strengthen food security initiatives in similar contexts.

Acute myeloid leukemia (AML) is a hematopoietic malignancy characterized by uncontrolled proliferation of myeloid progenitor cells in the bone marrow. The standard chemotherapy in treating AML cases is anthracycline, including doxorubicin; however, it could cause severe side effects if administered continuously at high doses, making it less tolerable for some patients. Evodia suaveolens, a herbal medicine, is known to contain active compounds and anti-cancer activities, which could inhibit cancer cell proliferation. This study aims to determine the combined effect of doxorubicin and Evodia suaveolens on inhibiting the G2/M cell cycle phase and proliferation in AML cells. This experimental study used HL-60 cells which were divided into six treatment groups: K- (control), K+ (doxorubicin 0.2 µg/mL), D1-D3 (combination of doxorubicin 0.2 µg/mL and Evodia suaveolens leaf extract with concentrations of 0.2, 0.4, 0.8 mg/mL) and D4 (Evodia suaveolens leaf extract 0.8 mg/mL). The findings indicated that the G2/M phase of the cell cycle was most effectively inhibited at the D3 dose (doxorubicin at 0.2 µg/mL combined with Evodia suaveolens leaf extract at 0.8 mg/mL), which also significantly reduced cell proliferation. Consequently, this study concludes that the combination of doxorubicin and Evodia suaveolens effectively inhibits the G2/M cell cycle phase and proliferation in AML cells.

The large number of activities without being balanced with sufficient consumption of drinking water can affect the hydration status of the body, namely the occurrence of dehydration. The study aims to describe the short-term hydration status of D-III Nursing Study Program students in terms of the PURI test results. The method used is the PURI test, namely the urine self-check method which is carried out in 2 tests. The research also used a survey method to support the results of the PURI test. Based on the results of the study, the short-term hydration status of D-III Nursing Study Program students based on the PURI test on the results of the 1st test showed that most of the students 15% experienced mild dehydration and 72% experienced severe dehydration. This is related to the habit of students who never bring drinking water to campus and most students do not consume enough water during the range of lecture hours until the lecture is over. The results of the 2nd PURI test showed that 76% of students had good hydration status because prior to testing students were encouraged to consume sufficient amounts of water. The results of the study show that students awareness of meeting body fluids to maintain body fluid homeostasis needs to be increased.

An analysis of the antibacterial ability of Vibrio sp. has been carried out from the ethanol extract of Ulva lactuca seaweed and its phytochemical study. Analysis of the antibacterial ability of Vibrio sp. using the disk diffusion method was the main thing carried out in this research, then the extract yield was calculated from the maceration process of Ulva lactuca seaweed, as well as phytochemical analysis to support the antibacterial ability of Ulva lactuca seaweed against the bacteria Vibrio sp. The results of the extraction of Ulva lactuca seaweed with ethanol solvent obtained a yield of 3.67%. The results showed a moderate antibacterial activity of Vibrio sp. from Ulva lactuca seaweed extract at a concentration of 100% was 17.3 mm. Weak antibacterial activity was at a concentration of 75% of 12.525 mm and extracts below a concentration of 75% did not have inhibitory power against Vibrio sp bacteria. Phytochemical studies of Ulva lactuca seaweed found secondary metabolite compounds in the form of alkaloids, flavonoids, steroids, tannins and saponins. Based on the results of this research, it is hoped that the antibacterial ability of Vibrio sp. can be further investigated from ethanol extract of Ulva lactuca seaweed in vivo.
