The villages of Sukasari, Pulosari, Pandeglang, Banten are agricultural areas. Most of the residents of Sukasari Village grow rice in the rice fields, while others are traders, employees and so on. In general, residential areas are located in villages. Most people's houses are permanent, made of brick walls. In general, the village in Sukasari Village at the foot of Mount Karang has a moderate population density (not too dense). The houses in Sukasari Village generally have a yard. The working area of Sukasari Village consists of 3 hamlets, 8 RWs, 26 RTs with a population of 4,239 people. In the work area of Sukasari Village itself, there are only health facilities in the form of 1 midwife practice and 6 posyandu. Pulosari District is one of the sub-districts in Pandeglang Regency. This sub-district has an area of 27.62 km2 and has a population of 28,885 people. Pulosari District consists of 9 (nine) villages, namely Banjarnegara, Kaduhejo, Koranji, Sanghiangdedek, Cilentung, Karyawangi, Sukasari, and Sukaraja. Sukasari Village itself has an area of 4.20 km2. An unbalanced ratio between population and existing health facilities can cause health problems, because if health problems are resolved then the success of an area's development can be said to be successful. Even though we are facing the COVID-19 pandemic, we must not ignore other health problems. Therefore, we will implement a PKM program to check the quality of drinking water for residents in the Sukasari, Pulosari, Pandeglang, Banten Village areas. "We do not yet have the courage to invite residents, even for medical purposes." In connection with this, we need to convey that our PKM officers will only have 2 people to take drinking water samples from sources in RW 04 and 05 (± 20 houses). We will check the quality of the drinking water, and the results can provide input for the health of the population. Drinking water quality checks include levels of Cl, Mn, nitrate, detergent, dissolved solids, pH, organoleptics and coliform bacteria.

Galactose-1-phosphate uridyltransferase (GALT) is an important enzyme involved in galactose metabolism. Understanding the factors influencing GALT activity is critical to elucidate its physiological role and potential therapeutic implications in galactosemia. In developing new drugs, chicken intestine/liver powder can be used as an enzyme source, GALT, to treat galactosemia. Therefore, it is necessary to research the characterization of the GALT enzyme in chicken intestine and liver powder. In this study, we investigated the influence of temperature, pH, and substrate level on GALT enzyme activity using an experimental approach in vitro. The optimum pH extraction results show that the optimum pH for the extraction of the chicken intestine and liver GALT is pH 7, with activity values of 0.47 units/mL and 0.3953 units/mL, respectively. The optimum temperature for the extraction of chicken intestine and liver GALT is 37℃ with substrate hydrolysis capabilities of 0.48 U/mL and 0.57 U/mL, respectively. Meanwhile, the optimum substrate content is 400x. These insights provide a valuable foundation for further research aimed at comprehensively understanding GALT function, developing targeted interventions for disorders of galactose metabolism, and possible application in the development of new drugs for galactosemia

BackgroundKretek cigarettes contain less nicotine and tar than conventional cigarettes. Exposure to cigarette smoke occurs mainly in the respiratory tract, resulting in histometric changes. The aim of this study was to evaluate the effect of filtered kretek cigarette smoke on bronchial histometric measurements in male Sprague-Dawley rats. MethodsAn experimental laboratory study was conducted involving 18 male Sprague-Dawley rats, aged 2-3 months, ranging from 150 to 250 grams in body weight. They were randomized into group 1 (controls) and experimental groups 2 and 3. Group 2 was exposed to filtered cigarette smoke at a dose of 1 stick/day and group 3 to 2 sticks/day. Treatment time for all groups was 30 days. Observation of bronchial histometric measurements of the lumen include, length, width, area, and perimeter. In addition, the bronchial mucosal and smooth muscle layers were also measured. The one way-ANOVA test was used to analyze the data. ResultsThe mean area and mean perimeter of the bronchial lumen of the rats were significantly greater in group 1 than in groups 2 and 3 (p=0.000). The mean bronchial smooth muscle area of the rats in group 1 was smaller than the mean in group 2, which was in turn smaller than the mean in group 3 (p=0.000). Apparently the rats in the treatment groups had undergone bronchoconstriction. ConclusionExposure to filtered kretek cigarette smoke at a dose of 1 stick/day as well as 2 sticks/day for 30 days caused bronchial mucosal hyperplasia and bronchoconstriction in male rats.

The aging process is associated with changes in hormone levels. There is a noticeable change in estrogen levels in women, while in men, there is a change in testosterone levels. In the elderly, as a result of the aging process, changes in these hormone levels affect handgrip strength, and cognitive function. In both women and men, the function of several organs is influenced by sex steroid hormones, namely Oestrogen and androgens. There are two theories of steroid action mechanism on target cells, namely steroid hormone action mechanism genomically and non-genomically. The function and action mechanism of steroid hormone is important because it is the basis of the hormonal aspect for muscle mass, handgrip strength, and cognitive function. Due to the aging process, hormonal changes in the elderly are different compared to the previous period. This has consequences for changes in metabolic processes that affect the body’s condition, including changes in the composition of bones, muscles, and other tissues, such as the brain. In the aging process, it is important to pay attention to nutritional factors because they contribute to hormone levels that help maintain muscle mass, body mass index, hand grip strength, and cognitive function. In the brain, the sex steroid hormone has activating and organizational effects mediated by intracellular or transmembrane G-protein-coupled receptors. Articles published in English in the last 9 years (from 2014 to 2023) were retrieved from Science Direct, PubMed, Springer link, Oxford and Nature using relevant searching terms. The fact that testosterone bioavailability is predominated in the brain in relation to its activity and significant positive association with processing speed, sustained attention, and working memory in older men. To obtain a better quality of life for the elderly, nutritional factors must be considered to maintain optimal sex steroid hormone levels, hand grip strength, and cognitive function.

Adolescence is a vulnerable developmental period marked by increased risk of mental health problems. Coping skills and empathy are important psychological factors that may influence adolescent mental well-being. This study examined the relationships among coping skills, empathy, and mental health among high school students using a cross-sectional quantitative design with 152 participants. Data were collected using the Brief COPE, Basic Empathy Scale (BES), and Self-Reporting Questionnaire-20 (SRQ-20), and analyzed using Pearson correlation. Findings indicated that adaptive coping skills were significantly associated with fewer symptoms of emotional mental disorders. In contrast, empathy showed a significant positive correlation with mental disorder symptoms. This paradoxical finding suggests that while empathy is socially beneficial, high levels of empathy may increase psychological vulnerability when not accompanied by adequate emotional regulation. These results highlight the importance of strengthening adaptive coping strategies while simultaneously fostering balanced empathy supported by emotional regulation skills in adolescent mental health interventions.
