Introduction: The usage of traditional medicines in Indonesia has recently increased following the rise in regional COVID-19 cases. They were used to alleviate the symptoms of patients with pre-existing condition such as heart diseases, diabetes mellitus, and inflammation. They were also used to boost peoples immune system. Loranthus ferrugineus (Loranthaceae) and Peperomia pellucida (Piperaceae) were two medicinal plants used as anti-diabetes drugs.   
Aim: This study aimed to measure the anti-diabetic activity of extracts of L. ferrugineus branches and the aerial parts of P. pellucida.    
Method: Dried branches of L. ferrugineus were macerated using n-hexane, ethyl acetate, and methanol, respectively. Fresh aerial parts of P. pellucida were macerated with methanol and reduced the volume in vacuo. The extract was fractionated with n-hexane and ethyl acetate. These extracts and its fractions were dried and tested in vitro with α-glucosidase.    
Results: α-Glucosidase inhibitory activities of ethyl acetate and methanol of L. ferrugineus were 89.21% and 92.98% at 500 ppm. However, there was no significant activity detected for the n-hexane extract.  α-Glucosidase inhibitory activities of methanol extract, and its n-hexane and ethyl acetate fractions of P. pellucida were 8.26%, 0.83% and 28.19% at 500 ppm.    
Conclusion: The methanol extract of L. ferrugineus and the ethyl acetate extract of L. ferrugineus are considered to have potential to be developed further as therapeutics.

Background: The need for accessibility to health facilities, including pharmacies, hospitals, health centres, health clinics, and others, increases due to population growth in Indonesia. The approach to mapping the geographic location of health facilities needs to be used as a policy reference in determining the achievement of national health care coverage.

Objective: This study aims to see the distribution of pharmacy locations in Surabaya and its relationship with the population and epidemiological parameters.

Method: Geographic information of pharmacies in Surabaya was collected from a database provided by the Indonesian Ministry of Health. Population data in 2019, including the number of district residents in the Surabaya area, the number of hospitals and clinics, and the number of disease cases, were obtained from the Central Statistics Agency of Surabaya.

Result: A total of 791 pharmacies are spread across 31 districts in the city of Surabaya. The ratio of pharmacies number to the population per district varies from 1:1426.7 to 1:49806.0. The number of pharmacies per district significantly correlates with the number of hospitals and clinics in each district of Surabaya (r = 0.784).

Conclusion: The distribution of pharmaceutical service facilities (pharmacies) in Surabaya is still uneven and centralised, following hospitals and clinics distribution in each district.

Authors: Yusransyah  , Halimah Eli , Suwantika Auliya A.
Published: March 2022

Background: Since hypertension prevalence has increased, its economic burden has also increased in all regions, including Pandeglang District in Banten Province, Indonesia. In 2014, the government launched a chronic disease management programme (Prolanis) to optimise hypertension treatment in Primary Healthcare Centres (PHCs) through the Social Health Insurance Administration Body (BPJS Kesehatan). Pharmacists' counseling is important in this as it can increase the effectiveness of hypertension treatment.       
Objective: To investigate the cost-effectiveness of pharmacists’ counselling for Prolanis hypertension patients at PHCs.
Methods: An experimental study was conducted at 16 PHCs using a purposive sampling method. The total sample included 96 Prolanis hypertension patients divided into two groups of 48 participants (an intervention and control group). Incremental cost-effectiveness ratio (ICER) was applied by comparing the cost per quality-adjusted life-year (QALY) gained in both groups. A validated EuroQol-5 Dimension-5 Level (EQ-5D-5L) questionnaire and its Indonesian value set were employed to measure patient quality of life, and the local GDP per capita threshold for cost-effectiveness was used.         
Results: Pharmacists' counseling intervention is cost-effective (ICER: IDR.2,000-28,307 per QALY-gained) within several scenarios with varying fees. Sensitivity analysis showed that the patient's utility score and the pharmacist`s counseling fee were the most influential parameters impacting the ICER.   
Conclusion: Pharmacist`s counselling can be considered as a promising intervention to optimise Prolanis hypertension treatments at PHCs.

Introduction: Curcumin (Crc) is widely used as an antioxidant and an anti-inflammatory agent. Its low solubility limits its oral bioavailability, thus the need to develop a transdermal nanoformulation of Crc.   
Aim: This study aimed to obtain the stable formula of Crc-loaded nanoemulgels (Crc-NEGs) possessing good characteristics.   
Methods: The nanoemulsion (NE) was prepared by titration of the water phase into the mixture of oil, surfactant, and cosurfactant. Crc-NEs optimum formula was obtained by the simplex lattice design (SLD) method. Crc-NEGs were prepared using Carbopol 940 as the gelling agent, and subsequently, its freeze-thaw stability was observed. The ex vivo permeation study of Crc-NEGs was conducted using Franz diffusion cell.   
Results: The optimum formula of Crc-NEs showed good characteristics in terms of transmittance, particle size, polydispersity index, and zeta potential. Crc-NEGs were found stable through freeze-thaw stability. The ex vivo permeation study illustrated the higher amount of Crc penetrated from NEGs compared to the control (p <0,05).   
Conclusion: The Crc-NEGs formula has the potential to be the novel effective delivery method of curcumin.

Authors: Al-Aradi Hadeer , Alnajm Fahad , Al-Khafaji Amer
Published: March 2022

The Zubair Formation is main prolific reservoirs in the Rumaila oilfield in southern Iraq. The petrophysical assessment of the Zubair Formation was carried out using a suite of open-hole logs from eight wells along with the Rumaila North oil fields, in Basra. Based on THE neutron, density and Gamma Ray logs, the Upper Sand Member of the Zubair Formation is divided into the alternate units of the sand and shale and defining their boundaries. Based on the obtained results, the Upper Sand Member was divided into three main pay units: AB, DJ, and LN, separated by two insulating shale units designated C and K. The unit DJ was subdivided into four secondary reservoir units: D, F, G, H, and the LN unit, which is split into L, M, and N. High porosity, high oil saturation and a high net-to-gross ratio were found in the petrophysical investigation. The porosity types are good (from 15 to 20%), very good (20-25%) and excellent (more than 25%) except wells R-559 and R-256, which has medium permeability, all the wells have good to excellent permeability. The net pay for the reservoir unit thickness ranges from 5 to 59m in all wells, resulting in significant hydrocarbon productivity due to strong hydrocarbon saturation, good effective porosity, and low shale volume.

Carbon fiber reinforced polymers (CFRP) have an enormous potential in mass reduction of vehicles and therefore also CO2 emissions. Also, their contribution to noise reduction is considerable. There are, however, challenges during designing as CFRP are not isotropic materials so each application has to be viewed individually according to the current function. The goal of presented project was in using the advantages of CFRP materials for application in gearbox design for an electric vehicle and a research of potential for mass and noise reduction. There was a reference conventional gearbox provided by project partners KIMM (Korea Institute of Machinery and Materials) and Samyang company. The gearbox in electric vehicle is a significant source of noise because of high RPM and absence of combustion engine, so using CFRP can help in noise reduction. The high RPM also lead to higher frequencies that are uncomfortable for people. The first goal was to design and manufacture a CFRP gearbox casing and embedded differential case. That includes specification of material, layout and shape with use of FEM analysis in order to achieve sufficient mechanical properties comparable with those of the reference gearbox. These properties include for example stiffness of casing in bearings in order to achieve small deflection of shafts and thus better contact of gears. Another part of this project was done in order to explore a potential use of filament-wound shafts in gearboxes. There were several versions of hybrid shafts (CFRP/steel) manufactured and then steel gear rings were bonded on the surface of the shafts. There was also a reference steel shaft manufactured. The shafts were later tested on closed-loop test stand and the results of noise, vibration and transmission error of CFRP shafts were compared with the reference steel shaft. Another comparison was focused on evaluation of mass and moment of inertia reduction.

Cobalt toxicity from industrial exposure and medical metal prosthesis has been linked to neurological problems such as motor dysfunction. The goal of this study was to find out whether Prosopis africana (PA) seed extract had ameliorative effects on the cerebellum of adult Wistar rats exposed to cobalt chloride (CoCl2). 60 male Wistar rats were grouped into 4 (n=15). Rats were treated with CoCl2 or CoCl2 in combination with PA seed extract (PAE) at 50mg or 100mg orally for 14 days. Control rats received distilled water for the same period. The findings showed that CoCl2 caused neurobehavioural impairment in rats by reducing exploratory activities, increasing anxiety, and significantly (p<0.05) reducing hanging latency along with a low limb impairment score. Co-treatment with PAE on the other hand, enhanced these parameters to levels comparable to control, reduced hydrogen peroxide (H2O2) and malondialdehyde (MDA) in cerebellar tissues, while also improving superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities. Furthermore, PAE50mg or 100mg significantly (p<0.05) reduced proinflammatory biomarkers such as Interleukin 1 beta (IL-1β) and tumour necrosis factor (TNF-α). In the histology and immunohistochemistry, CoCl2 treated groups showed severe cytoplasmic vacuolations and nuclei fragmentation in Purkinje neurons, as well as elevated astrocytic expression of glial fibrillary acidic protein (GFAP), which was alleviated by PAE therapy. Thus, when PAE was administered, cerebellar Purkinje cell integrity was improved, antioxidant status was boosted, and lipid peroxidation in the cerebellum was suppressed. Hence, PAE ameliorated CoCl2 induced alterations by reducing oxidative stress, enhancing anti-oxidant enzyme status and decreasing inflammation.

The data from these 22 studies were meta-analyzed by the standardized effect size difference method or Cohen d for the fixed effects model. All statistical operations were performed using the second edition of comprehensive meta-analysis software. Results: The results showed that the average effect size of the studies is 0/434 for the fixed effects model and 0/477 for the random effects, both of which are significant. Because the effect sizes were heterogeneous, moderators were searched. The results showed no significant difference between the effect size of the studied studies according to the research design and the gender of the subjects. However, there was a substantial difference between the effect of studies on the effectiveness of play therapy on children's behavioural disorders according to the subject's age, the type of independent variable and the number of play therapy sessions. Conclusion: Holding play therapy sessions ultimately and in multiple sessions and at a young age can improve more behavioural disorders in children.

One of the commonest anatomical variations of the root canal morphology includes the C- shaped canal configuration, frequently observed in second mandibular molars, but may be detected in other tooth morphotypes also. Very frequently, the first mandibular molars necessitate an endodontic therapy as they are often caries-prone and tends to be the first erupting permanent posteriors. The complexities of this root canal diversity might often make canal negotiation, debridement, and obturation cumbersome for the clinician. The detection and exploration of the fan-shaped regions and intricacy of the C-shaped morphology can be enhanced by radiographic and clinical diagnostics. Hand as well as rotary instruments, together with sonics/ultrasonics, could be used to adequately manage this unusual canal arrangement. The current case report describes the diagnosis and management of an unfamiliar C-shaped canal morphology in first mandibular molar and emphasizes the imperative role of CBCT, improved magnifying aids like microscope and good choice of an endodontic sealer for its efficient handling

Introduction: The SARS-CoV-2 virus was first reported in Wuhan China in Dec 2019, since then 279 million have been infected and 5.4 million have died. This has raised the question where did the SARs-CoV-2 virus originate? Methodology: In this study, the literature was reviewed, and the scientific and intelligence evidence assessed. Interviews were made with scientists and victims involved in the creation of the virus in both the United States and China. Results: The evidence suggest that the SARs-CoV-2 virus began as bat virus which was then manipulated in the lab via gain of function research in the United States funded by the National Institutes of Health under Dr. Fauci. This proto-biological weapon was then given to the Chinese and passed through Uighur prisoners. It is hypothesized that the modest common Altaic ancestry between American Native Americans and the Uighur from North Central Asia may in part account for the increased death rates of Native Americans in the United States. Conclusion: The SARS- CoV-2 virus with near scientific certainty originated in the United States as a proto-biological weapon which was further clinically developed in China in a collaborative effort as a biological weapon to target ethnic and racial minorities by both China and the United States.
RESERVAS DE LA BIOSFERA Y COMPETENCIAS ESTATALES: UNA PROBLEMÁTICA RELACIÓN
Authors: LAZCANO BROTONS IÑIGO

En 2007 se ha producido un cambio en relación al tratamiento jurídico de las Reservas de la Biosfera, manifestado en dos direcciones. En primer lugar, a través de la regulación reglamentaria, por primera vez, de la composición, organización y funciones del Comité español del programa MaB. Regulación que, aunque centrada en aspectos puramente organizativos y de relación con el organismo internacional en desarrollo de esta política sobre Reservas de la Biosfera, atribuye al citado órgano ciertas funciones de coordinación y dirección. En segundo lugar, se ha aprobado la Ley 42/2007. De 13 de diciembre, del Patrimonio Natural y de la Biodiversidad. En esa norma se recoge, también por vez primera, la categoría de Reserva de la Biosfera como categoría específica de espacio natural protegido. El problema será entonces determinar si el quantum de funciones que sobre este tipo de espacios ha asumido el Estado vulnera o no las competencias autonómicas en la materia.

2007an, aldatu egin da Biosfera Erreserben tratamendu juridikoa, eta aldaketa hori bi norabidetan gauzatu da. Batetik, lehenengo aldiz, MaB programaren Espainiako Batzordearen osaera, antolaketa eta funtzioak arautu dira erregelamendu bidez. Arautze hori, batez ere, antolaketa-alderdiei buruzkoa eta Biosfera Erreserben politika garatzeko nazioarteko erakundearekin izan beharreko harremanei buruzkoa da; baina, horrez gain, koordinazio- eta zuzendaritza funtzio batzuk esleitzen dizkio aipatutako organoari. Bigarrenik, 42/2007 Legea onartu da, abenduaren 13koa, Natura Ondareari eta Biodibertsitateari buruzkoa. Arau horretan, naturgune babestuaren kategoria espezifiko gisa jaso da Biosfera Erreserba kategoria ¿lehendabiziko aldiz hori ere¿. Arazoa, horrenbestez, honakoa da: erabakitzea ea Estatuak horrelako guneei dagokienez bere gain hartu dituen funtzioek urratu egiten dituzten ala ez autonomia-erkidegoek gai honetan dituzten eskumenak.

In 2007 a change in the regulation of the Biosphere reserves took place. Firstly, with the regulation for the first time of the membership, organization and tasks of the Spanish Committee of the MaB programme. Regulation that, albeit focused on purely organizative issues and on the relationship with the international body that develops this policy concerning biosphere reserves, confers on the aforementioned body some coordination and managing tasks. Secondly, Act 42/2007, from December 13, of National Heritage and Biodiversity was enacted. In this statute, it is also established
for the first time the status of biosphere reserve as a specific status of protected natural area. Therefore, the problem shall be to know whether the quantum of tasks assumed by the State infringes or not the powers of Autonomous Communities in this field.
RÉGIMEN JURÍDICO DEL EJERCICIO DE COMPETENCIAS POR LOS ÓRGANOS MUNICIPALES
Authors: ÚBEDA TARAJANO FRANCISCO EUGENIO
Published: March 2022

En el presente artículo se estudian los distintos regímenes de organización municipal previstos en la vigente normativa de régimen local así como las modificaciones previstas en el Anteproyecto de Ley Básica del Gobierno y Administración Local. Dicho análisis se efectúa desde la perspectiva de las relaciones internas de los diversos órganos de gobierno y administración municipales. Se presta especial atención a las peculiaridades que presentan tanto el ejercicio directo de competencias por estos órganos como las técnicas más habituales de transferencia del ejercicio de la competencia. Por último se hace una breve referencia a las consecuencias jurídicas que el incorrecto ejercicio (directo e indirecto) de las competencias tienen sobre los actos administrativos emanados de dichos órganos.

Artikulu honetan, tokiko errejimeneko indarreko araudian aurreikusitako udal-antolakuntzako errejimenak aztertzen dira, bai eta gobernuaren eta tokiko administrazioen oinarrizko legearen aurreproiektuan aurreikusitako aldaketak ere. Azterketa gobernuko organoen eta udal-administrazioen arteko barne harremanen ikuspegitik dago landuta. Arreta berezia ematen zaie, batetik, organo horiek horrelako eskumenak zuzenean erabiltzeak dakartzan berezitasunei, eta, bestetik, eskumena eskuordetzeko teknika ohizkoenei. Azkenik, modu laburrean azaltzen dira, eskumenak modu ezegokian erabiltzearen ondorioz, organo horietatik eratorritako administrazio-egintzetan izaten diren ondorio juridikoak.

This article examines the various municipal organization regimes that are envisaged in the current legislation of Local Regime as well as in the intended modifications to the Preliminary Draft of the Basic Law of Government and Local Administration (Anteproyecto de Ley Básica del Gobierno y Administración Local). Such analysis is done from the perspective of internal relationships among the various government bodies and municipal administrations. We give special focus on the peculiarities related to the direct execution of competencies by these government bodies as
well as on the most usual techniques employed in the transfer of such competencies. Lastly, we make brief mention of the juridical consequences that arise from the incorrect exercise (whether directly or indirectly) of said competencies and its effects on administrative acts coming from such government bodies.
