Abstract

Sekretori IgA (SIgA) adalah salah satu kelas andibodi yang terdapat dalam saliva, yang dihasilkan dalam bentuk dimerikIgA oleh sel plasma lokal (PCs) pada stroma glandula saliva dan kemudian ditransportasi melalui epitel sekretori olehpolimer Ig reseptor (pIgR), yang disebut juga dengan membran komponen sekretori (SC). Pada permukaan mukosaSIgA bersama dengan mukus akan mengekslusi antigen-antigen. Tujuan penulisan artikel ini adalah untuk menjelaskanperan SIgA dalam meningkatkan pertahanan mukosa mulut terhadap bakteri patogen Streptokokus mutans. Bakteri inimerupakan penyebab utama terjadinya karies gigi, karena kemampuannya untuk melekat pada permukaan gigi, yangmemungkinkan terbentuknya kolonisasi pada permukaan gigi melalui pembentukan biofilm. Perlekatan Streptokokusmutans ini akan dihambat oleh SIgA dengan mengintervensi protein perlekatan bakteri yang disebut Ag I/II. Hal inimemungkinkan SIgA untuk mencegah perlekatan bakteri pada permukaan, sehingga dapat mencegah inisiasi terjadinyakaries gigi. Sebagai kesimpulan, sekresi SIgA saliva terhadap Ag I/II Streptokokus mutanstelah terbukti dapat mencegahkolonisasi bakteritersebut dirongga mulut manusia

Abstract

The synthetic unit hydrograph (HSS) is used as a predictive tool in hydrological studies, particularly to estimate the peak discharge due to design rainfall, which is very useful in water infrastructure planning and flood control. This study aims to develop more accurate HSS parameters by considering the influence of morphometry, namely, the watershed form factor and the watershed area. The study involved 10 watersheds located on the island of Java, which were selected as study sites to provide a broader and more representative context for the variation in characteristics in the study area. The methods used include watershed morphometric analysis to determine the location and shape factor of the watershed, hydrograph analysis to produce unit hydrographs per watershed/sub-watersheds, and hydrograph analysis to determine the size of the sub-watershed and explicit modeling technique with multiple linear regression, which is the writing of a mathematical model that shows the relationship between the dependent variables (Qp and Tp) and the independent variables (A and FD, respectively). The result of the study is a HSS model on Java Island with parameters FD and A obtained the following equation: peak discharge (Qp) = 18.465 - 25.730 (FD) + 0.039 (A), and peak time (Tp) = 2.962 - 0.766 (FD) + 0.001 (A), where FD is the watershed form factor and A is the watershed area. Correlation coefficient (R) for peak discharge (R = 0.962) and peak time (R = 0.974). Coefficient of determination (R2) for peak discharge (R2 = 0.926) and peak time (R2 = 0.948).

Abstract

Introduction: Low back pain (LBP) is a leading cause of disability worldwide. While physical activity (PA) is a cornerstone of LBP management, the precise nature of the dose-response relationship remains debated, with studies reporting protective, harmful, and null effects. This comprehensive systematic review synthesizes evidence from observational studies to clarify the association between PA levels and LBP, exploring how this relationship is modified by activity domain, intensity, population characteristics, and pain chronicity. Methods: A systematic review was conducted, screening studies based on pre-defined criteria: adult populations (≥18 years) with non-specific LBP; assessment of PA as a primary exposure; and reporting of LBP outcomes (e.g., incidence, severity, disability). Eligible designs included observational studies (cross-sectional, cohort, case-control), systematic reviews, and meta-analyses that used validated measurement tools. Data were extracted on study characteristics, PA and LBP assessment methods, primary association results, moderating factors, and study quality. Results: Eighty studies were included, comprising 56 cross-sectional and 16 prospective cohort designs, with sample sizes ranging from 30 to 365,307 participants. The findings reveal a context-dependent relationship. Moderate-to-vigorous leisure-time PA was consistently associated with a protective effect against chronic LBP (RR range 0.84-0.90) (1,2). Optimal doses were identified at approximately 400-670 minutes of MVPA per week or 1800-2400 MET-min/week (3,4). In contrast, occupational PA (18,20), heavy domestic labor (17), and sedentary behavior (9,12,23) were associated with increased LBP risk. The relationship was often U-shaped, with both very low and very high activity levels conferring greater risk (1,4,10,25). Protective effects were more pronounced in older adults (≥50 years) (10,11), women (12,13), and obese individuals (14-16). Physical activity was more strongly associated with reduced disability (33,36) and the prevention of chronicity (2,6) than with acute pain episodes. Discussion: The heterogeneity in findings is explained not by contradiction but by the context-specificity of the PA-LBP relationship. The domain of activity (leisure vs. occupation) and its intensity are critical determinants of effect. While moderate leisure activity is protective, obligatory and high-intensity occupational demands can be harmful. PA's benefits appear to accumulate over time, primarily preventing the transition to chronic pain and reducing disability rather than eliminating acute episodes. The association is further modified by individual factors like age, sex, and BMI, and is mediated by psychological factors such as fear-avoidance beliefs. Conclusion: This review concludes that the relationship between physical activity and low back pain is non-linear and highly context-dependent. Recommendations should promote moderate-to-vigorous leisure-time physical activity for the prevention and management of chronic LBP, particularly in at-risk populations. However, they must be personalized, considering an individual's age, occupation, BMI, and psychological state. Future research should prioritize the use of objective activity measures and longitudinal designs to further delineate causal pathways and domain-specific dose-response relationships.
