Published: October 2022

The marosok is a tradition of buying and selling livestock using hand movements and facial expressions in the bargaining process. The marosok tradition has denotative and connotative meanings associated with Minangkabau culture. The purpose of this study was to determine the meaning of denotation and connotation of the marosok tradition with an ethnographic approach using Symbolic Interactionism Theory and semiotic analysis of Pierce. This research method is qualitative by conducting literature study and interviews using snowball sampling technique to M. Azhadi Dt. Bosa as key informant who directs researchers to Desmon Korina and Hadiyati who understand the marosok tradition in the Payakumbuh community. This study shows that the tools, hand movements and expressions in the marosok tradition have meanings that must be understood by the parties involved in the transactions. The sarong is a covering tool that shows marosok tradition is only carried out by men. Finger gestures indicate digits up to millions, increasing, or decreasing bidding. Expressions indicate approval or rejection of the offered price. The marosok tradition ends with handshake and smile between the seller and the buyer. The marosok tradition creates healthy competition where the prices are only known by the parties concerned. However, this process is not transparent, the buyer can only estimate the weight and condition of the livestock by seeing and touching the livestock directly, so the buyer must be very careful in choosing livestock with good quality. The marosok tradition must be maintained so that the media is needed to teach how to do marosok to the younger generation. Apart from being a buying and selling transaction, the marosok tradition can be used as an attraction for tourists to come to Payakumbuh.

Published: October 2022

Background: The most typical consequence of diabetes mellitus is diabetic retinopathy. An important part of the etiology of diabetes and diabetic retinopathy is played by oxidative stress. Malondialdehyde is a dialdehyde that is moderately toxic and is frequently used as a marker for oxidative stress as well as lipid peroxidation.
Objectives: To assess the serum malondialdehyde levels in diabetic patients with and those without retinopathy and to compare these levels to controls .In additions to, investigate the relationship between serum malondialdehyde level and long glycemic control, the glycated hemoglobin (HbA1c).
Patients and Methods: This case-control study included (120) individuals from 40 to 70 years of age. They were divided into three groups: Group 1: 40 type 2diabetic patients with retinopathy, Group 2 :40 type 2 diabetic patients without retinopathy, and Group 3 40 controls .The biochemical testes included fasting blood glucose measured by Cobas c 311 systems, glycated hemoglobinHbA1c measured by Cobas c 111 systems, and serum malondialdehyde (MDA) measured by enzyme linked immunosorbent assay (ELISA).
Results: A higer mean value of (MDA) was found serum diabetic patients with and without retinopathy as compared to control (p=0.0001). As well as a significantly higher mean value of serum (MDA) in diabetic patients with retinopathy as compared to those without (p=0.0001).A significant positive correlation was found between serum(MDA) and HbA1C in diabetic patient with retinopathy group (r=0.931,p=0.0001) .
Conclusion: Higher serum levels of malondialdehyde is an indicator of increased lipid peroxidation that may be involved in pathogeneses of retinopathy in uncontrolled type 2 diabetic patients.

Acoustic and photoacoustic characterization of micron-sized perfluorocarbon emulsions
Authors: M Strohm Eric , Gorelikov Ivan , Matsuura Naomi , Kolios Michael 
Published: October 2022

<p> Perfluorocarbon droplets containing nanoparticles (NPs) have recently been investigated as theranostic and dual-mode contrast agents. These droplets can be vaporized via laser irradiation or used as photoacoustic contrast agents below the vaporization threshold. This study investigates the photoacoustic mechanism of NP-loaded droplets using photoacoustic frequencies between 100 and 1000 MHz, where distinct spectral features are observed that are related to the droplet composition. The measured photoacoustic spectrum from NP-loaded perfluorocarbon droplets was compared to a theoretical model that assumes a homogenous liquid. Good agreement in the location of the spectral features was observed, which suggests the NPs act primarily as optical absorbers to induce thermal expansion of the droplet as a single homogenous object. The NP size and composition do not affect the photoacoustic spectrum; therefore, the photoacoustic signal can be maximized by optimizing the NP optical absorbing properties. To confirm the theoretical parameters in the model, photoacoustic, ultrasonic, and optical methods were used to estimate the droplet diameter. Photoacoustic and ultrasonic methods agreed to within 1.4%, while the optical measurement was 8.5% higher; this difference decreased with increasing droplet size. The small discrepancy may be attributed to the difficulty in observing the small droplets through the partially translucent phantom. </p>
Perfluorocarbon bubbles as photoacoustic signal amplifiers for cancer theranostics
Authors: Fernandes Donald A. , Kolios Michael 
Published: October 2022

<p>Phase change nanoemulsions have been proposed as theranostic agents, using light to induce vaporization into bubbles (also called optical droplet vaporization). The current work uses perfluorohexane nanoemulsions (PFH-NEs) stabilized by a highly biocompatible and optically absorbing fluorosurfactant shell. Once vaporized, the bubbles can be used for contrast enhanced ultrasound (CEUS) imaging but also to enhance photoacoustic (PA) signals due to the presence of bubbles and optical absorbing shell material. The formation and expansion of these gas filled bubbles leads to increasing photoacoustic signals for imaging. Compared to other contrast agents which may not give stable signals due to photo-degradation, these contrast agents are shown to be stable up to 24 hours. The source of PA signal enhancement is through the presence of long lasting perfluorohexane (PFH) bubbles resulting from the optical vaporization. These bubbles generated from the PFH-NEs directly generate photoacoustic signals due to the optical absorption from the fluorosurfactant shell, but also secondary signals from the subsequent scattering of the photoacoustic waves from the PFH bubbles. In addition, the pressures generated from vaporization of NEs and ability to load chemotherapeutic agents enable these nanoparticles to also be used for cancer therapy by contributing to drug delivery and transport. </p>

Pada masa pandemic Covid 19, Rata- rata siswa diharuskan belajar di rumah hanya dengan online class saja. Berdasarkan hasil observasi ke sekolah SD Al-Wasliyah, Dalam era New Normal saat ini, pihak sekolah telah memperbolehkan siswan bersekolah dengan cara memberikan jadwal/ gelombang untuk seminggu hanya 3 kali saja. Hal ini yang mengakibatkan Kurangnya pemahaman dan keahlian Wali kelas sebagai ibu di kelas untuk intens dan mengerti kondisi anak. Sehingga SD Al-Wasliyah menerapkan STIFIn tes terhadap semua gurunya, hal ini dikarenakan turunnya kinerja guru, minimnya pendekatan psikologis ke anak. Selama ini Kepala Sekolah hanya mampu menugaskan acak guru-guru yang akan menjadi wali kelas. Sehingga untuk pemetaan Kemampuan kompetensi Paedagogik, Keterampilan, Profesionalitas mereka masih kurang, Karena masih juga ada wali kelas yang belum mampu mengamankan kelas dan melakukan pendekatan ke siswa agar didalam kelas itu minat dan prestasi anak meningkat. Penelitian ini bertujuan untuk mengetahui apa ada hubungan antara STIFIn dalam meningkatkan Kompetensi Paedagogik dan Profesionalisme guru upaya pemilihan Wali kelas. Dalam Penelitian ini dilaksanakan di SD Al- Wasliyah Bromo Medan, Khususnya untuk guru- guru yang akan diangkat menjadi wali kelas pada tahun ajaran baru mendatang. Sebanyak 14 orang guru, akan di tes dan di uji baik dengan kompetensinya maupun keahliannya dengan STIFIn tes ini.
Siyasi İktidarın Sınırlandırılması ve Anayasal Denge Denetimi Düşüncesinin Kökeni

Published: October 2022

Sahip olduğu güç kullanma tekeli ile diğer iktidarlardan farklı olan siyasal iktidar, bir yandan toplumun devamını sağlarken, öte yandan bu gücün kötüye kullanımı tehlikesini içinde barındırır. Siyasal iktidarın sahip olduğu gücün kötüye kullanımını ve bunun yıkıcı sonuçlarını engellemenin yolu, ancak bu iktidarın sınırlandırılması, dengelenmesi ve denetlenmesiyle mümkündür. Özgürlüğünün ve güvenliğinin kayıt altına alınmış bir iktidardan geçtiğinin bilincinde olan insanoğlu, siyasi iktidarın ortaya çıkmasından bugüne, bu iktidarı sınırlandırmanın araçlarını ve kurallarını bulmaya çabalamıştır. Antik Yunanla başlayan bu düşünsel çaba, modern devletin ortaya çıkmasıyla başka bir boyut kazanmış, tarihin ilk yazılı anayasası kabul edilen Amerikan Anayasası’nın yapıcıları, yazmış oldukları anayasayla getirdikleri frenler ve dengeler adı verilen bir sistemle, bu düşünsel mirasa önemli katkılar sunmuşlardır. Her bir erkin, bir diğer erk üzerinde bazı etkilere sahip olmasını ifade eden frenler ve dengeler sistemi, Amerika Birleşik Devletleri başkanlık sistemini başarılı kılan en önemli unsurdur. Bu çalışmada, siyasal iktidarın sınırlandırılması ve anayasal denge denetimin yalnızca düşünsel kökenleri incelenmiş, iktidarı sınırlandırmanın, denge ve denetimin araçlarına yer verilmemiştir. Anayasal denge ve denetleme, 2017 anayasa değişikliği ile başka adlarla anılsa da fiilen başkanlık sistemine geçilen Türkiye’nin de güncel meselelerindendir.

The “Thin on the Outside Fat on the Inside” TOFI_Asia study found Asian Chinese to be more susceptible to Type 2 Diabetes (T2D) compared to European Caucasians matched for gender and body mass index (BMI). This was influenced by degree of visceral adipose deposition and ectopic fat accumulation in key organs, including liver and pancreas, leading to altered fasting plasma glucose, insulin resistance, and differences in plasma lipid and metabolite profiles. It remains unclear how intra-pancreatic fat deposition (IPFD) impacts TOFI phenotype-related T2D risk factors associated with Asian Chinese. Cow’s milk whey protein isolate (WPI) is an insulin secretagogue which can suppress hyperglycemia in prediabetes. In this dietary intervention, we used untargeted metabolomics to characterize the postprandial WPI response in 24 overweight women with prediabetes. Participants were classified by ethnicity (Asian Chinese, n=12; European Caucasian, n=12) and IPFD (low IPFD &lt; 4.66%, n=10; high IPFD ≥ 4.66%, n=10). Using a cross-over design participants were randomized to consume three WPI beverages on separate occasions; 0 g (water control), 12.5 g (low protein, LP) and 50 g (high protein, HP), consumed when fasted. An exclusion pipeline for isolating metabolites with temporal (T0-240mins) WPI responses was implemented, and a support vector machine-recursive feature elimination (SVM-RFE) algorithm was used to model relevant metabolites by ethnicity and IPFD classes. Metabolic network analysis identified glycine as a central hub in both ethnicity and IPFD WPI response networks. A depletion of glycine relative to WPI concentration was detected in Chinese and high IPFD participants independent of BMI. Urea cycle metabolites were highly represented among the ethnicity WPI metabolome model, implicating a dysregulation in ammonia and nitrogen metabolism among Chinese participants. Uric acid and purine synthesis pathways were enriched within the high IPFD cohort’s WPI metabolome response, implicating adipogenesis and insulin resistance pathways. In conclusion, the discrimination of ethnicity from WPI metabolome profiles was a stronger prediction model than IPFD in overweight women with prediabetes. Each models’ discriminatory metabolites enriched different metabolic pathways that help to further characterize prediabetes in Asian Chinese women and women with increased IPFD, independently.

BackgroundPlasmodium knowlesi causes zoonotic malaria across Southeast Asia. First-line diagnostic microscopy cannot reliably differentiate P. knowlesi from other human malaria species. Rapid diagnostic tests (RDTs) designed for P. falciparum and P. vivax are used routinely in P. knowlesi co-endemic areas despite potential cross-reactivity for species-specific antibody targets.MethodsTen RDTs were evaluated: nine to detect clinical P. knowlesi infections from Malaysia, and nine assessing limit of detection (LoD) for P. knowlesi (PkA1-H.1) and P. falciparum (Pf3D7) cultures. Targets included Plasmodium-genus parasite lactate dehydrogenase (pan-pLDH) and P. vivax (Pv)-pLDH.ResultsSamples were collected prior to antimalarial treatment from 127 patients with microscopy-positive PCR-confirmed P. knowlesi mono-infections. Median parasitaemia was 788/µL (IQR 247-5,565/µL). Pan-pLDH sensitivities ranged from 50.6% (95% CI 39.6–61.5) (SD BIOLINE) to 87.0% (95% CI 75.1–94.6) (First Response® and CareStart™ PAN) compared to reference PCR. Pv-pLDH RDTs detected P. knowlesi with up to 92.0% (95% CI 84.3-96.7%) sensitivity (Biocredit™). For parasite counts ≥200/µL, pan-pLDH (Standard Q) and Pv-pLDH RDTs exceeded 95% sensitivity. Specificity of RDTs against 26 PCR-confirmed negative controls was 100%. Sensitivity of six highest performing RDTs were not significantly different when comparing samples taken before and after (median 3 hours) antimalarial treatment. Parasite ring stages were present in 30% of pre-treatment samples, with ring stage proportions (mean 1.9%) demonstrating inverse correlation with test positivity of Biocredit™ and two CareStart™ RDTs.For cultured P. knowlesi, CareStart™ PAN demonstrated the lowest LoD at 25 parasites/µL; LoDs of other pan-pLDH ranged from 98 to &gt;2000 parasites/µL. Pv-pLDH LoD for P. knowlesi was 49 parasites/µL. No false-positive results were observed in either P. falciparum-pLDH or histidine-rich-protein-2 channels.ConclusionSelected RDTs demonstrate sufficient performance for detection of major human malaria species including P. knowlesi in co-endemic areas where microscopy is not available, particularly for higher parasite counts, although cannot reliably differentiate among non-falciparum malaria.
