Introduction: The aim of this study was to compare the results of recovery of patients with benign prostatic hyperplasia through two surgical methods, including TURP (Transurethral resection of prostate) and modified open prostatectomy (OP) was performed.
Methods: In this clinical trial study, 100 patients with benign prostatic hyperplasia who were referred to the Urology Clinic of Shahid Rahnemon Hospital from 1996 to 1997 were admitted to the study on the inclusion and exclusion criteria and were randomly assigned to one of the surgical groups using the modified OP or TURP approach. The results of the study in both groups were analyzed through SPSS 16 software. Due to the normal distribution of data, T-test and Chi-Square statistical tests were applied to analyze the data.
Results: The mean age of the patients undergoing modified OP surgery and the TURP patients was 70.36 ± 8.35 and 69.39 ± 8.44 years, respectively. The maximum urinary flow (Qmax) was significantly higher in the modified OP group than in the TURP group (P <0.001). In addition, the mean duration of operation in the modified OP group was significantly lower than the TURP group (P = 0.001). The increase in obstructive and excitatory symptoms in the TURP group was statistically significant 6 months after surgery (P = 0.009 and P = 0.011, respectively).
Conclusion: While TURP is the standard therapy for patients with BPH‎, the findings of this study indicate that modified OP is a safer and more reliable procedure with fewer postoperative complications. It is recommended that modified OP be considered as a treatment for the patients with BPH.

Published: April 2022

Many therapeutic properties have been reported for saffron (Crocus sativus L.), including anti-inflammatory effects due to its strong antioxidant properties and the ability to accumulate oxygen free radicals by components such as crocin and crocetin. The aim of this study was to evaluate the anti-inflammatory effect of saffron on the treatment of patients with periodontitis. 40 patients with moderate to severe generalized periodontitis were selected and divided randomly into the intervention and control groups. The intervention group was instructed to use a mouthwash containing aqueous saffron extract twice a day for 2 weeks; while the control group members were asked to apply chlorhexidine as the gold standard mouthwash. The participants’ gingival probing depth index, modified gingival index, and gingival bleeding index were measured before and one month after the intervention. The patients’ level of satisfaction on the taste of mouthwash was also measured. T-test and Mann-Whitney test were run for statistical analysis. A significant difference was observed in terms of the gingival indices before and four weeks after using both saffron and chlorhexidine mouthwashes (p value: 0.001). However, no statistically significant difference was found between two groups. Patients reported higher levels of taste satisfaction after using saffron aqueous extract mouthwash than the chlorhexidine mouthwash (p value: 0.021). Saffron mouthwash showed comparable therapeutic effect to the gold standard mouthwash, chlorhexidine, and may be helpful as an adjunct treatment for management of periodontitis.

Functional dyspepsia (FD) is a common gastroduodenal disorder that can be long-lasting. In the present study, we aimed to investigate the effect of herbal medicine, Ghors-e-Vard (Vard), on clinical symptoms in FD patients. Seventy adult FD patients according to the Rome IV criteria and without Helicobacter pylori infection were included. Participants were randomly allocated to either Vard or placebo group for 4 weeks of intervention. Treatments were given orally in a double-blind fashion (500 mg, three times a day, and half an hour after each meal). Patients were evaluated prior to and following 2, 4, and 8 weeks after the intervention, in terms of changes in the total score of gastrointestinal symptoms rating scale (GSRS), Depression Anxiety Stress Scales (DASS-21), scores of various components of the 36-item short-form health survey (SF-36), and any reported side effects. The differences of GSRS and DASS-21 total scores from baseline to the end of intervention were significantly larger in Vard group (P<0.001). Except for reflux, the other subtypes of FD symptoms were decreased with a significantly greater effect in Vard group (P < 0.05). Also, changes in the total score of SF-36 at 4 and 8 weeks after the intervention were significantly greater in Vard group (P<0.001). Except for the reflux, improvement of gastrointestinal symptoms, along with depression, stress, and anxiety, as well as the quality of life in Vard group, was significantly superior to the placebo group. These findings suggest that the Vard, as a complementary therapy, may have a promising effect on resolving the FD symptoms.‎

Corchorus olitorius L. is a medicinal herb with anti-inflammatory, laxative, and tonic properties, which is effective on the treatment of cancer and tumors. In this study, the extraction efficiency of supercritical fluid extraction (SFE) and ultrasound-assisted extraction (UAE) of C. olitorius as well as their antioxidant activities were investigated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical. For this purpose, central composite block cube star and central composite design were employed to determine the optimal conditions. Thereafter, the qualification analysis of the effective ingredients of C. olitorius was done by LC-ESI-MS in negative mode. The results of LC-MS showed that C. olitorius includes phenolic and flavonoid compounds such as caffeic acid, p-coumaric acid, trans-ferulic acid, quercetin, naringenin, cirsiliol, cirsilineol, quercetrin, and naringin. Moreover, the SFE efficiency of extraction and IC50 value was obtained 4.25% and 1208.99 µg/mL, respectively. Also, the UAE efficiency of extraction and IC50 of antioxidant activity was obtained as 15.29% and 994.284 µg/mL, respectively. These results confirmed that the efficiencies of extraction and antioxidant activity of UAE were higher than that of SFE; however, the SFE is an environmentally friendly method and consumed less organic solvent.

Jushanda (decoction), often used in traditional medicine, has many drawbacks like disagreeable taste, bulky dose, cumbersome preparation, and short stability. Therefore, in the present study, jushanda nazla (JN) was modified and optimized into a sugar-based (SBS) and sugar-free (SFS) syrup dosage form and evaluated for various physicochemical parameters, microbial contaminations and antimicrobial activities. JN was concentrated and reduced to minimum quantity by heating and twelve batches of SBS and five batches of SFS were prepared for optimization. Out of these, the best batch of SBS and SFS were selected based on consistency and minimum bulk. The best batches were further evaluated for the physicochemical parameter, microbial and heavy metal contamination. The finished products were also evaluated for antimicrobial activity against selected microbes. SBS was optimized with 170 mL JN reduced to 50 mL, sugar 40% (w/v) and consistency of one wire. SFS was optimized with 170 mL JN reduced to 30 mL, and 96 mg of aspartame. Organoleptic characters, ash value, viscosity, specific gravity and pH of finished products were satisfactory. The concentration of total phenolic, flavonoid, tannin, alkaloid and glycyrrhizin and chlorogenic acid were comparative in JN, SBS and SFS. SBS and SFS passed the WHO guideline for microbial and heavy metal contamination. Finished products showed significant antimicrobial activity against Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae and Salmonella. Analytical data of SBS and SFS showed significant optimistic results hence, generated data can be used for future reference. However, developed formulations should be further evaluated for their stability, safety and clinical efficacy.

Data that states the number of events in a certain period of time is called count data. Poisson regression is one of the regression models included in the application of GLM that can be used to model the count data. In Poisson regression, there are assumptions that must be met, namely the mean and variance of the response variables must be the same (equidispersion). Several models that are able to overcome overdispersion due to excess zero are the Zero Inflated model and the Hurdle model. This study examines the characteristics of parameter estimation in the modeling of quantified data that is overdispersed due to excess zero using the Zero Inflated Poisson (ZIP), Zero Inflated Negative Binomial (ZINB), Hurdle Poisson (HP) model and the Hurdle Negative Binomial (HNB) model in cases of diphtheria. in West Sumatra in 2018. Based on individual parameter testing and AIC values, the HP model provides better performance than the ZIP, ZINB, and HNB models. So the Hurdle Poisson model is better used in this case than other models

The mathematical model of prey-predator interaction is one of the stages of solving mathematical problems by simplifying events that occur in mathematical form. In this research, we discuss a prey-predator model using a type II Holling response function without harvesting and a prey-predator model using a type II Holling response function with harvesting. The purpose of this research was to explain the formation of a prey-predator model with a type II Holling response and a preypredator model with a type II Holling response with harvesting, to determine the stability at the equilibrium point of the model, and to create a model simulation using several sample parameters. The results obtained were three equilibrium points for the prey-predator model with type II Holling response without harvesting and two equilibrium points for the prey-predator model with type II Holling response with harvesting. The stability at two equilibrium points of the prey-predator model using the type II Holling response function without harvesting was asymptotically stable and the stability at one equilibrium point in the prey-predator model using the type II Holling response function in the presence of harvesting in the prey population was asymptotically stable. The comparison of numerical simulations showed that the number of predator population without harvesting was greater than the number of predator population with harvesting.

Partial differential equations are often used to explain physical phenomena, one of which is the wave equation. One application of the wave equation is in plucked strings. This study describes the formation of a wave equation from guitar strings, determines the solution to the wave equation by using the variable separation method and certain boundary conditions and initial conditions, determines the amplitude of the wave, and simulates the movement of the wave based on the initial position of the plucked string. The result obtained is the wave equation of the guitar strings. When the string is plucked, the string will vibrate and produce a wave that can be formulated as a wave equation in the form of a homogeneous second order partial differential equation. The solution to this equation is in the form of a series. If given the initial conditions of plucking in the form of a function, then the amplitude of the wave is obtained. Simulations are given to see the movement of the amplitude and wave on the strings through three cases of the initial position of plucking the strings, namely: less than half, half, and more than half the length of the strings. The behavior of these amplitudes and waves is a characteristic or characteristic of the waves produced from a plucked guitar string

The research was carried out in two villages, i.e., Sungai Lumbah Village and Bangkit Baru Village, with a total of 50 informants. The results showed that the pre-flood mitigation carried out by the community was by elevating the rice storage area. The community has never received socialization by the local government regarding flood prevention, but they did it on their own initiative and formed a flood alert team. When there was a flood, they set up a relief center to help the affected people. After the flood, the community cleaned up the flood marks in their respective homes and repaired the damaged agricultural land. Flood management is still carried out on the community's own awareness and is carried out voluntarily.

The population problem in Indonesia is the rate of population growth and the imbalance in its distribution.  The transmigration program aims to balance the distribution of the population by regulating and directing people who have a high density to move to areas that are still sparsely populated, with the hope that development and population distribution can be evenly distributed. Hegar Manah Village.  Hegar Manah Village is a village located in Bintang Ara District, Tabalong Regency, which was one of the transmigrant placement villages in 1993. In 1993 transmigrants came to Hegar Manah Village as many as 300 families (KK), consisting of 150 families from the other side (Java Island) and 150 local transmigrant families (Kalimantan), in 2020 there are only 30 transmigrant families left. This study aims to analyze the factors that cause transmigrants to persist in living in Hegar Manah Village, Bintang Ara District, Tabalong Regency, by examining 4 factors that are considered influential on the reasons for transmigrants to survive, namely by examining the transmigrant economic sector, public infrastructure facilities, land/land ownership and social cultural or adaptation of transmigrants to the local physical and social environment.  This study uses a quantitative method with a descriptive approach.  Data collection was carried out by distributing questionnaires/questionnaires to 27 families of indigenous transmigrant communities who still survived.  Data analysis used descriptive statistics by calculating the percentage of each answer from respondents, and factor analysis by calculating the results of respondents' answers. The results showed that the transmigrant community persisted in living in Hegar Manah Village, Bintang Ara District because 1) they had sufficient land for the reason to survive.  2) good social culture or tolerance for very high differences, so as to create social and cultural harmony without discriminating against ethnicity, race, or religion.  3) economic or welfare factors are not the reason for transmigrants to stay.  4) the factor of infrastructure is not the reason for transmigrants to stay.Keywords: Transmigrant, survival factors

Penelitian ini bertujuan menentukan kelas kesesuaian lahan tanaman porang (Amorphophallus muelleri Blume) di Kecamatan Kare. Penelitian dengan pendekatan kuantitatif bermetode survei. Unit lahan didapatkan dari interpretasi peta kemiringan lereng, jenis tanah, dan penggunaan lahan Kecamatan Kare Kabupaten Madiun skala 1:110.000. Sampel penelitian ini berjumlah tujuh satuan unit lahan. Analisis dengan metode matching(pencocokan) antara kualitas lahan dengan kriteria keseuaian lahan untuk tanaman porang. Hasil evaluasi menunjukkan bahwa ada empat unit lahan (D2-2-4, D2-3-4, D2-3-5, dan D2-4-5) sangat sesuai (S1), sedangkan tiga unit lahan (D2-3-1, D2-4-1, dan D2-4-4) sesuai (S2) untuk budidaya tanaman porang. Faktor pembatas di ketiga unit lahan tersebut meliputi ketersediaan oksigen (oa) dan retensi hara (nr). Maka implikasi penelitian ini diharapkan adanya upaya perbaikan terhadap faktor pembatas lahan. Ini dapat meningkatkan kualitas lahan menjadi sangat sesuai (S1) untuk tanaman porang. Maka, Pengembangan pusat kawasan agropolitan tanaman porang nantinya berada di Kecamatan Kare untuk wilayah Jawa Timur.
Problematizing identities and differences: notes post-modern, “(pos)critical” and post-structuralist the school and the curriculum
Authors: Sousa Galdino Rodrigues de , Rossi Marcos Antônio
Published: April 2022

This article is  based on  a correlation of bibliographic sources under a qualitative approach, influenced by postmodern society and poststructuralist discussions of knowledge in their descriptions and analyses. Concepts and effects of identities and differences are discussed, as well as their possible conformations in the postmodern school and in the “(post)critical” and poststructuralist curriculum. It is concluded that in post-modernity, the subject assumes different identities from different influences, and the school is an important place for the problematization and construction of this movement, including inside the power relations towards difference. A "(post)critical" curriculum is defended, which does not oppose critical pedagogies and post-critical pedagogies, nor constrain their possible approaches and potential against hegemonic, fighting against social injustices and fostering (trans)formations and/or pluralization of identities . Furthermore, in this curriculum, in addition to broadly considering postmodern issues, post-structuralist issues are also considered, especially with regard to schools and the curriculum itself as practices of meaning and representation.
