Abstract

Chloroform and aceton are commonly used in washing test, while both are unfriendly to human health. This research is aimed to evaluate if those chemicals are really needed foe such purpose by seeing the washing power with or without those chemicals. There are four conditions of washing test: Involving both as usual (CA); chloroform only (C); chloroform and ethanol instead (CE); and None of both (OO). Washing test was carryout within a 0% and 1% of detergent. Two Way ANOVA Statistical analysis revealed that there was a very significant differences among the treatments, and Duncan analysis showed that with or without chloroform and aceton resulting in the same category of washing power, except the CE treatment resulted in a lower washing power. Hence there is a choice weather chloroform and aceton be involved in the procedure.

Abstract

The integrated laboratory is one of the learning facilities at the university, especially to support the implementation of practicum. In laboratories that are full of activities, bacterial contamination often occurs which can interfere with the smooth running of research and practicum. This contamination is often caused by a lack of sterility in the work process and less than optimal indoor air quality. Therefore, it is important to know the type and number of bacteria found in the laboratory to prevent further spread of contamination. This study aims to isolate and identify bacteria in the Integrated Laboratory of the Faculty of Medicine, Universitas Muslim Indonesia. The method used in this study was descriptive research with a laboratory observational design, which was carried out by macroscopic and microscopic means to determine the type of microorganisms and the number of bacterial colonies. The results showed four types of bacteria found, namely Staphylococcus sp., Klebsiella pneumoniae, Staphylococcus epidermidis, and Bacillus sp., which were isolated from air and swab results. Airborne bacteria had the highest number of colonies at 14 CFU, while swab bacteria were found at 200 CFU. Although bacterial colonies were found in the laboratory, this number is still considered safe for the number of bacteria in the laboratory. Based on these findings, it is recommended that laboratory facilities pay more attention to aspects of cleanliness and sanitation as a whole.

Abstract

The tuberculosis (TB) vaccine contains a weakened form of the TB-causing agent. Currently, much research has focused on developing an effective and safe TB vaccine through genetic engineering. This review aims to analyze genetic engineering techniques in the production of tuberculosis (TB) vaccines. The analysis was conducted by gathering research data from various studies published between 2014-2024, available in PubMed, ScienceDirect, and Google Scholar, using relevant keywords. Based on the literature review, several innovative methods in genetic engineering were identified, such as Polymerase Chain Reaction (PCR), Enzyme-Linked Immunosorbent Assay (ELISA), in silico methods, multi-epitope vaccine development, and protein fusion-based vaccine development. Although there are challenges related to vaccine stability and clinical safety testing, innovations in genetic engineering technology hold the promise of significant progress in developing a more effective and durable TB vaccine. Among these methods, protein fusion-based and multi-epitope vaccines show the most promising potential in terms of effectiveness and long-lasting immune response.

Abstract

Tobacco smoke contains more than 4000 kinds of constituents, including nicotine, tar, carbonic monoxide, polycyclic aromatic hydrocarbons, and heavy metals. Because of the complexity of tobacco smoke components, the toxicological mechanism is notably complicated. Most studies have reported reduced semen quality, reproductive hormone system dysfunction and impaired spermatogenesis, sperm maturation, and spermatozoa function in smokers compared with nonsmokers. Many studies have reported plant tissue contain secondary metabolites such as saponin, terpenoid, alkaloid, and flavonoid with antioxidant properties. Tropical fruit species that is known rich antioxidants content is banana, and one cultivar  banana is Ketip. The aim of this research is to study the effect of Ketip banana peel  ethanol extract on sperm viability of mice following cigarettes exposure. Data analysis showed that tobacco smoke exposure tend to dccrease sperm viability but insignificantly. Treatment with ethanol extract of ketip banana tend to reduce sperm viability. It is concluded that ethanol extract of ketip banana insignificantly increase sperm viability.

Abstract

Premature rupture of membranes (PROM) is one of the main causes of the high newborn mortality rates and maternal mortality rate (MMR), which continue to be significant global health challenges. The purpose of this study is to examine the association between the occurrence of PROM at the North Lombok Regional Public Hospital and maternal age, parity, and fetal anomalies. This research uses a case-control study design and is an analytical observational study. Purposive sampling was utilized to choose the research sample, which included 186 people in total. The chi-square test was used to analyze the data and determine how the variables related to one another. According to the study's findings, 120 (64.5%) respondents were not at risk, while 66 (35.5%) were. Of the respondents, 131 (70.4%) had parity without risk, while 55 (29.5%) had parity at risk. Respondents with fetal abnormalities were 28 (15.1%) and 158 (84.9%) had normal fetuses. Age and the frequency of premature membrane rupture are related; the p-value is 0.022 and the OR is 2.145. With a p-value of 0.024 and an OR of 2,203, there is a correlation between parity and the frequency of premature membrane rupture. Premature rupture of the membranes and fetal abnormalities do not correlate, as indicated by the p-value of 0.538. The incidence of PROM is correlated with maternal age and parity, although there is no significant link between PROM and fetal abnormalities.

Abstract

People with diabetes mellitus (DM) experience impaired insulin function so that glucose cannot enter the cells so that blood glucose levels increase. Several factors such as body mass index, age, and gender can also affect blood glucose levels. If not controlled properly, high blood glucose levels can cause various complications. The purpose of this study was to analyze the relationship between body mass index, age, and gender with blood glucose levels in patients with type 2 diabetes mellitus at the Internal Medicine Polyclinic, Praya Regional General Hospital (RSUD). The design of this study is cross-sectional and observational. With a sample size of 108, sequential sampling was the method used. The Continuity Correction test and the Chi-Square test were used to analyze the data. The study's findings revealed a highly significant correlation between blood glucose levels and body mass index (p-value <0.001, OR 11.261, 95% CI 4.137-30.649). Blood glucose levels and age are significantly correlated (p-value = 0.018, OR 2.865, 95% CI 1.269-6.466). Blood glucose levels and gender are significantly correlated (p-value = 0.004, OR 3.567, 95% CI 1.575-8.077). In patients with type 2 diabetes mellitus at the Internal Medicine Polyclinic of Praya Hospital, random blood glucose levels were significantly correlated with body mass index, age, and gender, according to the findings of statistical tests. Uncontrolled random blood glucose levels were eleven times more common in obese respondents than in non-obese respondents.

Abstract

One of the most common diseases in the world, including in Indonesia, is diabetes mellitus, which can lead to complications such diabetic ulcers, which can raise the risk of death and amputation. It is believed that hypertension, as a risk factor in and of itself, contributes to the development of diabetic ulcers by causing both macrovascular and microvascular damage. This study aims to analyze the association between hypertension and diabetic ulcers in diabetes mellitus patients at the Mataram City Regional General Hospital (RSUD). This research is an analytical observational study with a case-control design. Sampling used purposive sampling technique. A total of 105 samples were selected with a 1:2 ratio between the case and control groups who met the inclusion and exclusion criteria. Data analysis was carried out using the Chi-Square test. There is a significant association between hypertension and diabetic ulcers (p-value = 0.028; OR = 2.771; 95% CI = 1.198–6.411). Subjects with uncontrolled hypertension were 3 times more at risk of developing diabetic ulcers.
