How to handle the administrative violations in the Election? A Discourse of Characteristic of Bawaslu Verdict
Authors: Yoga Luthfi Dwi
Published: October 2022

One of the impacts of strengthening the Election Supervisory Body (Bawaslu)’s authorityfrom the central level to Regency/City level in handling election administrative violations is to guarantee thecertainty of law for the justice seekers. This is based on the authority to examine and decide on allegations of handling election administrative violations. The authority to handle this violation is based on the Article 461 paragraph (1) of Law Number 7 of 2017 about Election. Bythe authority, Bawaslu is a semi-judicial or quasi-judicial institution. The output of the handling is in the form of verdict such as court verdict in general which have final and binding power and have execution force for the ranks of the Elections Commission (KPU). This executive power can be seen in verdict that can be directly executed without having to wait or require approval from the KPU through the issuance of verdict. As a final verdict, the verdict of Bawaslu, Provincial Bawaslu and Regency/City Bawaslu also have constitutive and condemnatory characteristic nature.With  these characteristics, the purpose of issuing a Bawaslu verdict is to finalizing administrative violation caseof the election. However, at the practical level, the nature of the final and binding does not apply to Provincial Bawaslu and Regency/City Bawaslu. This can be seen in the existence of legal remedies against the verdict through a request for correction to the RI Bawaslu (central).

Published: October 2022

Disharmony and regulation arrangement is one of the problems in Indonesia that has not been completely resolved. Efforts have been made by the government and various parties. But in reality, disharmony and regulation arrangement are still a problem in Indonesia. There needs to be an out of the box solution, one of which involves the judicial power to organize regulations. The researchers in this article have two problem formulations, namely (1) how is the arrangement of regulations through judicial power from the theoretical aspect? and (2) how is the arrangement of regulations through the Constitutional Court and the Supreme Court to realize a synchronized and harmonious simplification of regulations? First, regulatory arrangements can be made by the judiciary through instruments and processes called judicial review. Theoretically, judicial review can be used as an instrument and a process for structuring regulations so that they are synchronous and harmonious. In Indonesia, a judicial review has been applied to the authority of the Constitutional Court and the Supreme Court. This means that theoretically, regulatory arrangements can be made by the judiciary, in this case the Constitutional Court and the Supreme Court. Second, the judicial review carried out in the context of structuring regulations must be comprehensive on all types of laws and regulations and systematically tiered. Judicial review can also be done horizontally and vertically.

Development of sustainable bioproducts from microalgae biomass: Current status and future perspectives
Authors: Baala Harini Anandapadmanaban , Rajkumar Renganathan
Published: October 2022

Population and pollution make notable contributions to introducing novel sophisticated techniques. From vehicles to industries, the release of CO2 into the atmosphere and wastewater into the running water streams are key concerns. On the other hand, the population is responsible for the rapid manufacturing of all commercial goods. Microalgae are the only answer accessible for the aforementioned difficulties. Similar to plants, microalgae need CO2 and light to thrive and produce a variety of bioproducts such as carbohydrates, protein, lipids, vitamins, sterols, pigments, and silica. Physical (light, temperature, CO2, and UV), chemical (nutrient addition or depletion), enzymatic, and metabolic pathway reconfiguration, as well as indoor or outdoor growing, are highly regarded among the several optimization strategies to make desired products. Wastewater pollution is rectified by growing microalgae in nutrient-rich organic water for their growth, which is used to accelerate bioproducts. This review considers the use of bioproducts in food, animal and aquatic feed, fertilizer, biofuel, medicinal and nutraceutical sectors. This paper also provides different optimization strategies, which include physical and chemical means of extraction methods for enhancing bioactive products. Challenges and future recommendations for enhancing target bioproducts are discussed to overcome environmental issues.

Minimax identity with robust utility functional for a nonconcave utility
Authors: Bahchedjioglou Olena , Shevchenko Georgiy
Published: October 2022

The minimax identity for a nondecreasing upper-semicontinuous utility function satisfying mild growth assumption is studied. In contrast to the classical setting, concavity of the utility function is not asumed. By considering the concave envelope of the utility function, equalities and inequalities between the robust utility functionals of an initial utility function and its concavification are obtained. Furthermore, similar equalities and inequalities are proved in the case of implementing an upper bound on the final endowment of the initial model.
The warrior aristocracy of the Late Bronze Age Urnfield Period in County Somogy, south-western Transdanubia. The Lengyeltóti V hoard (County Somogy/Hungary)
Authors: Honti Szilvia , Jankovits Katalin
Published: October 2022

Discussed here is the presence of a warrior aristocracy in south-western Hungary, principally in County Somogy, during the early (and middle) Urnfield period (Br D–Ha A1-A2) based on the archaeological record. The period's offensive and protective weapons wielded by the warrior aristocracy during the Urnfield period (mid-thirteenth to ninth century BC) are exclusively known from hoards in this region; none have been recovered from burials. The Lengyeltóti V hoard contained a greave, a composite cuirass, a cheek-piece indicating the presence of a military aristocracy riding horses and wagons or chariots when going to battle and a realistic wheel model. The swords and spearheads were part of the period's offensive weaponry. The hoard's other articles represented the jewellery of the female aristocracy: a diadem, a torc and an ornamented disc pendant. The hoard contained over seven hundred items. In A. Mozsolics's view, the hoard could be assigned to the period lasting up to the close of the Hallstatt period (Ha A2). The rise of the warrior aristocracy began during the Br D, Br D/Ha A1 period, while its consolidation and heyday fell into the early Urnfield period (Ha A1). The aristocracy lived in hillforts – fortified settlements – which had a flourishing bronze industry. The number of settlements and burials declined drastically in the ensuing Ha B period in south-western Transdanubia.
Emerging mediaeval heritage: Environmental history research at Băgău (c. Alba, Romania) and the Bottomless Lake (Tăul fără fund)

Published: October 2022

The investigation of a 8.1 m long peat sequence from Tăul fără
fund (“Bottomless Lake,” Transylvanian Basin, Northern Romania) offers a series representing wetland development since the Middle Holocene. The most striking feature of the sequence is a cca. 900 year-long hiatus caused by peatcutting in the 14th century AD. An artificial reservoir was constructed there in the Late Middle Ages by the excavation of the uppermost peat layer, afflicting a significant environmental impact on this remote location. One of the oldest documented Hungarian settlements from the time of the Hungarian Kingdom (11th century AD, presumably with previous history) in Transylvania was discovered in the vicinity of the former reservoir by an archaeological field survey. By harmonising historical data and the exact chronological sequence of the borehole, the creation of the reservoir was inserted into the local history of the developing mediaeval settlement network at the time when some of the early settlements had been abandoned and a permanent village was established, with a church and upscale landowners, in the area of present-day Băgău in the 13th to 14th century AD. Significant environmental impacts have emerged during this transitional period around the reservoir.
La nostalgia de las cosas, la arqueología de los sentimientos y el trampantojo foucaultiano
Authors: Bermejo Barrera José Carlos
Published: October 2022

En la Historia y las Ciencias Sociales: Antropología, Sociología y Arqueología, los autores estructuralistas y postmodernos dejaron a un lado las ideas de hombre, sentimientos, valores y contingencia. Los nuevos conceptos de estructura, lenguaje y poder pasarían a ser las nuevas claves para explicar así el pasado y el mundo social. Sin embargo los gustos y sentimientos, que estos autores negaron de plano, estuvieron presentes en sus textos de un modo oblicuo.

En este artículo se expone ese doble vínculo textual a través del estudio de la historia de las cosas, la historia de los sentimientos y el análisis historiográfico de la obra maestra de Michel Foucault: Histoire de la folie á l´Âge classique.

Beta-glucosidase (BGL) is an enzyme involved in the hydrolysis of cellulose and plays an important role in many biological processes. This enzyme is widely available in animals, plants, and microorganisms. Expression of the recombinant enzyme in Escherichia coli is considered a suitable choice for high production via a fast growth rate and feasible manipulation. In this study, we optimised some conditions for the high soluble production of recombinant beta-glucosidase whose gene sequence was mined from the DNA metagenome of Cuc Phuong humus surrounding white rot fungi. The gene bgl was cloned in pET 22b(+) and expressed in the E. coli Rosetta 1 strain. Production of the recombinant BGL was examined at temperature ranges from 18 to 37oC. The recombinant BGL was obtained as a soluble form at low temperatures, and the optimal temperature was 25°C. In comparison to LB, TB, SB, PE media, mTB rich medium in presence of glucose produced the most BGL. Besides, the results assessing the inducer condition showed that the best IPTG concentration for producing the BGL was 0.3 mM IPTG. Furthermore, some fermentation conditions affecting the level of BGL production were assessed as the induction point and harvesting time. The BGL production was the most suitable when the cell at mid-log phase with an OD600 1 and harvesting time after 4 hours of induction. Importantly, the recombinant BGL had good activity on the esculin substrate plate. Based on the selected conditions, the recombinant BGL could be produced high amount to facilitate for future purification and characterization of the recombinant BGL.

Microgravity has been shown to markedly affect reproduction in humans and animals, especially reproductive organs such as the ovaries. Granulosa cells are one of the important components of the ovary, playing an important role in supporting oocyte maturation and fertilization. However, the effects of microgravity on granulosa cells have not been well characterized. This study aimed to assess the effects of simulated microgravity (SMG) on the cell cycle progression of porcine granulosa cells (pGCs). The pGCs were induced SMG for 72 h by Gravite® simulator, while cells of the control group were treated in normal conditions. Cell cycle analysis revealed that SMG condition induced an increase of the ratio of pGCs in the G0/G1 phase, leading to the cell cycle arrest phase, while the ratio of pGCs in the G2/M phase was decreased. There was no difference in the cell ratio of the S phase between the control group and the SMG group. Real-time RT-PCR analysis indicated that the expression of cdk4 and cdk6 transcripts of pGCs from the SMG group was lower than the control group. This down-regulation was also observed cyclin A and cyclin D1 transcript expression in pGCs from the SMG group. Immunostaining displayed the lower exhibition of microfilament and microtubule in pGCs from the SMG group comparing to the control group. Western blot analysis showed that the expression of β-actin and α-tubulin was reduced in pGCs from the SMG group. These changes contributed to the alteration of cytoskeletal structure, including microfilaments and microtubules, which affect cell division. These results revealed that the SMG condition induced changes in the cell cycle progression of pGCs.

Trichophyton rubrum is a causative agent responsible for human chronic dermatophytosis worlwide. It is a common causative agent of the dermatophyte infections and resistant to many antifungal drugs. Oxidative damaging agents belong to a strong antimicrobial group and have been intensively investigated. The synergistic oxidative damage can occur if the agents react with metal cations. Therefore, in this study the antifungal activity of formulas containing the two oxidative damaging agents, including hydrogen peroxide (H2O2) and 8-hydroxyquinoline (8HQ), in combination with metal cations has been determined to examine the synergistic damage in T. rubrum isolated from the skin of a dermatological patient. The isolate was identified by morphology observations, biochemical tests and sequence analysis of ITS1-4 gene, in comparison with the similar ITS nucleotide sequences of others. The obtained results showed that the isolated fungal strain had physiological and biochemical characteristics of T. rubrum with more than 99% identity of the T. rubrum CBS 392.58 ITS sequence with OL347577 accession numbers. The antifungal tests indicated that the combinations of 2 mM Cu2+ + 0.05% H2O2; 2 mM Cu2++ 0.005% 8HQ; 2 mM Cu2+ + 0.005% 8HQ + 0.05% H2O2 exerted the best antifungal activity against the isolated T. rubrum with the diameter of inhibition zones of 22, 25 and 28 mm, respectively. Among the combinations containing Zn2+, the only formula of 2 mM Zn2+ + 0.05% H2O2 exhibited the desired effect, while the combinations containing Fe2+ did not show any activity. Thus, our study suggested a potential use of Cu2+ + 0.05% H2O2; 2 mM Cu2++ 0.005% 8HQ and 2 mM Cu2+ + 0.005% 8HQ + 0.05% H2O2 formulas as new potential antifungal agents against T. rubrum due to their synergistic oxidative damage.

Published: October 2022

Psoriasis is a chronic autoimmune disease characterized by abnormal proliferation and differentiation of keratinocytes and infiltration of inflammatory cells into the site of inflammation. Plaque psoriasis is the most common type of psoriasis, affecting up to 80–90% of psoriasis cases. Among inflammatory cells, myeloid dendritic cells or Langerhans cells are mainly activated cells during the pathogenesis of psoriasis to induce activation and differentiation of naive T cells into T helper cells (Th)1 and Th17 cells. SH2 domain-containing protein tyrosine phosphatase (SHP) is a negative regulator of the phosphorylation of several proteins involved in cellular differentiation, growth and activation. Chronic inflammation promotes tumor progression, which is characterized by the release of carcinogenic antigens, including alpha-fetoprotein (AFP) and cancer antigen 125 (CA125) into blood and urine. They are common tumor markers to serve as predictors of cancer development and survival of cancer patients. To this end, blood samples of 103 psoriasis patients and 46 healthy subjects were collected. The mRNA expressions of SHP1 and SHP2 were examined by using quantitative RT-PCR and the serum levels of IL-6, TNF-α, IFN-γ, IL-17A, AFP and CA125 by ELISA. As a result, the mRNA level of SHP1 was higher expressed, whereas the level of SHP2 was unaltered in the patient group compared to the control individuals. Importantly, psoriasis patients had CA125 level higher than the clinical cutoff 35U/mL was 15.6%, while healthy individuals had CA125 level lower than 35U/mL. In addition, the serum TNF-α and IL-17A concentrations were significantly increased in the patient group. In conclusion, the results indicated the significant differences in expression of SHP1 gene and inflammatory response in psoriasis patients. This study further hint for investigations on the functional role of SHP1 in regulating activation of immune cells present in psoriasis patients.

Hypercholesterolemia is a major cause of cholesterol build-up in the coronary arteries, which can subsequently lead to heart disease or atherosclerosis. Cholesterol levels can be lowered by cholesterol-lowering drugs but some of these drugs may have harmful side effects, while supplementation of Lactobacillus has shown the potential to reduce serum cholesterol levels by virtue of bile salt hydrolase (bsh) activity. In this study, Lactobacillus plantarum VFE-04, L. rhamnosus VFE-08, and L. plantarum VFE-14, had been isolated from Vietnamese healthy adults, were able to deconjugate glycodeoxycholate (GDC) on MRS plates and MRS broth supplemented with GDC. In addition, deconjugating activity of L. plantarum VFE-04, L. rhamnosus VFE-08, and L. plantarum VFE-14 were also found in cell-free extract as expressed by amount of glycine that released in the supernatant. Four bsh genes including bsh1, bsh2, bsh3, and bsh4 have been identified by PCR in these strains. In addition, L. plantarum VFE-04, L. rhamnosus VFE-08, and L. plantarum VFE-14 also showed high ability to resist bile salts and low pH. The results of 16S rRNA gene analyses showed that L. plantarum VFE-04, L. rhamnosus VFE-08, and L. plantarum VFE-14 and had high similarity scores with L. plantarum ZZU 23 (100%), L. rhamnosus JCM 1136 (99%) and L. plantarum S7 (98.65%), respectively. This study suggests that L. plantarum VFE-04, L. rhamnosus VFE-08, and L. plantarum VFE-14 have the potential to be explored as probiotics in the management of hypercholesterolaemia in near future.

La trata de personas no es un fenómeno moderno. Al conocer un poco de historia, podemos encontrarnos con un sinnúmero de casos de seres humanos (en especial, personas vulnerables) que han sido víctimas de hechos de explotación y tratados como mercancía para beneficio de otros, quienes ejercen relaciones de poder y subyugación, atentando contra los derechos humanos primordiales, como el derecho a una vida sin sometimientos y el disfrute de la libertad, así como reduciendo a las víctimas a situaciones de inferioridad, en las que pierden su autonomía y, por consiguiente, se ven en la obligación de realizar actividades degradantes en contra de su voluntad. En este sentido, se considera que la trata de personas no solo es un delito, sino una grave violación a los derechos humanos, lo que requiere la suma de esfuerzos y acciones de los distintos entes gubernamentales, instituciones, grupos poblacionales y sociedad en general, a fin de combatir este flagelo que causa daños inimaginables en la vida de las víctimas.
