Published: May 2024

The homologous series of gaseous C1-4 alkanes represents one of the most abundant sources of short alkyl fragments. However, their application in synthetic organic chemistry is exceedingly rare due to the challenging C–H bond cleavage, which typically demands high temperatures and pressures, thereby limiting their utility in the construction of complex organic molecules. In particular, the formation of C(sp2)–C(sp3) bonds is crucial for constructing biologically active molecules, including pharmaceuticals and agrochemicals. In this study, we present the previously elusive coupling between gaseous alkanes and (hetero)aryl bromides, achieved through a combination of Hydrogen Atom Transfer (HAT) photocatalysis and nickel-catalyzed cross coupling at room temperature. Utilizing flow technology allowed us to conduct this novel coupling reaction with reduced reaction times and in a scalable fashion, rendering it practical for widespread adoption in both academia and industry. Density Functional Theory (DFT) calculations unveiled that the oxidative addition constitutes the rate-determining step, with the activation energy barrier increasing with smaller alkyl radicals. Furthermore, radical isomerization observed in propane and butane analogues could be attributed to the electronic properties of the bromoarene coupling partner, highlighting the crucial role of oxidative addition in the observed selectivity of this transformation.

Correct elaboration of N-linked glycans in the secretory pathway of human cells is essential in physiology. Early N-glycan biosynthesis follows an assembly line principle before undergoing crucial elaboration points that feature the sequential incorporation of the sugar N-acetylglucosamine (GlcNAc). The activity of GlcNAc transferase V (MGAT5) primes the biosynthesis of an N-glycan antenna that is heavily upregulated in cancer. Yet, the functional relevance and substrate choice of MGAT5 are ill-defined. Here, we employ a tactic termed bump-and-hole engineering to develop a bioorthogonal substrate analog for the activity of MGAT5. Chemoenzymatic synthesis is used to produce a collection of nucleotide-sugar analogs with bulky, bioorthogonal acylamide side chains. Protein engineering yields an MGAT5 variant that specifically uses one such substrate instead of the native nucleotide-sugar. We validate the enzymatic bump-and-hole system and show that the orthogonal enzyme-substrate pair is suitable to bioorthogonally tag glycoproteins. Through X-ray crystallography and molecular dynamic simulations, we establish the structural basis of bump-and-hole engineering, informing the design rules for bioorthogonal precision chemical tools.

Published: May 2024

Cardiotoxicity is the direct adverse effect of anticancer agents on the function or structure of the heart, occurring both during treatment and many years later. The manifestations of cardiotoxicity can be very different: heart failure, coronary heart disease, cardiomyopathy, myocarditis, pericarditis, and arrhythmias, including atrial fibrillation (AF). The incidence of AF in the cancer patient population during therapy is 20–30%. Current options of remote electrocardiogram monitoring ensure the timely detection and treatment of AF in cancer patients, including the administration of anticoagulants. The article presents a clinical case of a 59-year-old patient with squamous cell carcinoma of the lower third of the esophagus after the first course of the TPF polychemotherapy regimen (docetaxel, cisplatin, 5-fluorouracil) with AF detected using a single-channel electrocardiogram monitor in a smartphone case.

Published: May 2024

Background. The problem of urinary tract infections, including recurrent cystitis, and the choice of effective and safe means of treatment and prevention, taking into account the increasing burden of antibiotic resistance, are extremely relevant.
Aim. To evaluate the effectiveness and safety of the herbal medicine Canephron® N for the prevention of exacerbations of recurrent cystitis and its effect on metabolic parameters in patients with type 2 diabetes mellitus taking sodium glucose cotransporter type 2 inhibitors.
Material and methods. A prospective, randomized, open-label, parallel group study of 60 women without exacerbation of recurrent cystitis. The main group took the drug Canephron® N for 3 months, 2 tablets 3 times a day, and for the next 3 months they were monitored without taking the drug. The main evaluation parameters were: frequency of cystitis relapses, albumin/creatinine ratio in the morning urine, glomerular filtration rate, plasma lipid profile, glycemia and malondialdehyde in low-density lipoproteins.
Results. 3 months after the end of taking the drug Canephron® N, patients in the main group maintained a positive effect in reducing exacerbations of cystitis – 3.3 times less relapses of the disease (3 and 10%, respectively; p=0.038). The urine albumin/creatinine ratio, lipid profile, glycemia and malondialdehyde in low-density lipoproteins after a 3-month treatment period had positive dynamics, but in the long-term period they corresponded to the values at the inclusion stage, both in the main and control groups.
Conclusion. Prophylactic use of the herbal drug Canephron® N for 3 months is safe and reduces the frequency of relapses of cystitis in women with chronic cystitis against the background of diabetes mellitus taking sodium glucose cotransporter type 2 inhibitors, this effect persists for 3 months after discontinuation of the drug.

Published: May 2024

Defective mitophagy in renal tubular epithelial cells is one of the main drivers of renal fibrosis in diabetic kidney disease. Our gene sequencing data showed the expression of PINK1 and BNIP3, two key molecules of mitophagy, was decreased in renal tissues of VDR-knockout mice. Herein, streptozotocin (STZ) was used to induce renal interstitial fibrosis in mice. VDR deficiency exacerbated STZ-induced renal impairment and defective mitophagy. Paricalcitol (pari, a VDR agonist) and the tubular epithelial cell–specific overexpression of VDR restored the expression of PINK1 and BNIP3 in the renal cortex and attenuated STZ-induced kidney fibrosis and mitochondrial dysfunction. In HK-2 cells under high glucose conditions, an increased level of α-SMA, COL1, and FN and a decreased expression of PINK1 and BNIP3 with severe mitochondrial damage were observed, and these alterations could be largely reversed by pari treatment. ChIP-qPCR and luciferase reporter assays showed VDR could positively regulate the transcription ofPink1andBnip3genes. These findings reveal that VDR could restore mitophagy defects and attenuate STZ-induced fibrosis in diabetic mice through regulation of PINK1 and BNIP3.
Does Leadership Matter? Ahmadinejad, Rouhani, and the Change in Iranian Foreign Policy
Authors: Luleci Sula Cagla
Published: May 2024

Following Rouhani's victory in the 2013 presidential elections, Iran's foreign policy (IFP) underwent significant changes after over a decade under Ahmadinejad. To date, only a few academic studies have attempted to incorporate a specific individual-level theory into their respective analyses, even though a large body of literature contends that leadership change is the decisive factor in differences in Iran's policy towards the US and the EU. This study analyzes the leadership styles of Ahmadinejad and Rouhani to reveal the possible impact of decision-maker personalities on foreign policy, and to develop an account of the moderation in IFP. Accordingly, it asks, “How does leadership style influence IFP towards the 'Western world'?" Theoretically, the study benefits from Hermann’s ‘Leadership Trait Analysis’ to find out the impact of leaders’ personalities on foreign policy behaviors of states. Empirically, it analyzes both presidents’ spontaneously selected political speeches, consisting of their answers in interviews and press conferences. Methodologically, the study utilizes the software Profiler Plus to assess individual traits of leaders. Interpreting leadership trait scores of two presidents, the study concludes that certain leadership features allow the construction of foreign policies that are more moderate.

Metamaterials cloaking technology boasts a wide array of potential uses, spanning from military stealth applications to advancements in medical imaging. Metamaterials are specially engineered materials with unique characteristics absent in natural substances, such as negative refractive index, empowering them to manipulate electromagnetic waves in novel ways. The process of cloaking with metamaterials involves the bending of light or other electromagnetic waves around an object, effectively rendering it invisible or significantly reducing its detectability. This is accomplished through the intricate design of metamaterial structures capable of governing the flow of electromagnetic fields, diverting them away from the cloaked object. Among the most prominent applications of metamaterial cloaking is the development of invisibility cloaks. While primarily at the experimental stage, researchers have made substantial progress in crafting cloaking devices capable of concealing objects from specific wavelengths of light. These cloaks function by manipulating the path of light around an object, effectively creating the illusion of its absence. The potential applications of metamaterial cloaking encompass a broad spectrum, including invisibility, antennas and sensors, medical imaging, wireless communication, and stealth technology.

ÖZET Amaç: Ameliyat sonrası bulantı ve kusma yönetiminde alternatif ve tamamlayıcı tedavileri içeren çalışmaların incelenmesidir. Yöntemler: Bu sistematik derlemede Pubmed, Google Scholar, Siencedirect arama motorlarında yer alan ameliyat
sonrası bulantı kusma yönetiminde alternatif ve tamamlayıcı tedavi yöntemlerini içeren makaleler incelenmiştir. “Postoperatif mide bulantısı ve kusma”, “tamamlayıcı terapiler”, “hemşirelik bakımı” anahtar kelimeleri kullanarak
2017-2022 yılları arasında yayınlanmış, araştırmaya dahil edilme kriterlerine uygun 32 makale araştırma kapsamına alınmıştır. Bulgular: Ameliyat sonrası bulantı kusma için kullanılan alternatif ve tamamlayıcı tedavi yöntemlerinden
% 46.8’i aromaterapi uygulamaları, %31.2’i akupunktur yöntemleri, %9.3’ü müzik terapi, %6.2’si sakız çiğneme, %3.1’,i masaj ve %3,1’i hipnoz uygulamaları olarak bulunmuştur. Çalışmaların çoğunluğunda “Görsel Analog Bulantı-Kusma
Skalası” kullanılmıştır. Sonuç: Randomize kontrollü klinik çalışmalarda aromaterapi ve akapunktur uygulamalarının ameliyat sonrası dönemde görülebilecek bulantı-kusma gibi komplikasyonları önlemede etkili olduğu söylenebilir. Ancak
hipnoz, müzik terapi, masaj, sakız çiğneme gibi yöntemler konusunda kanıt düzeyi yüksek daha çok çalışmaya ihtiyaç olduğu sonucuna varıldı. Alternatif ve tamamlayıcı tedavi yöntemleri hem tek başlarına hem de antiemetik tedavi
ile birleştirerek, ameliyat sonrası dönemde bulantı ve kusmayı azaltabilir.

Aktivitas penangkapan ikan oleh nelayan di Kabupaten Kebumen mengalami kendala utama terkait dengan kondisi oseanografis dan ketidakpastian musim penangkapan ikan. Saat tidak musim, sebagian nelayan memiliki mata pencaharian lain yaitu bertani, beternak, dan lainnya. Namun tidak semua nelayan memiliki kemampuan tersebut, banyak nelayan yang menggantungkan hidupnya hanya sebagai nelayan. Tujuan penelitian ini yaitu mengidentifikasi potensi wilayah sebagai alternatif kegiatan ekonomi bagi nelayan dan memberikan rekomendasi mata pencaharian alternatif yang tepat bagi nelayan di Kabupaten Kebumen, contoh kasus di Desa Jogosimo. Pengumpulan data peluang kegiatan ekonomi alternatif dilakukan melalui survei potensi wilayah dan studi pustaka. Hasil tersebut selanjutnya dilakukan focus group discussion (FGD) untuk mendapatkan masukan terkait dengan pandangan nelayan terhadap alternatif mata pencaharian tersebut.  Analisis data dilakukan secara deskriptif berdasarkan hasil survei lapang dan FGD. Hasil identifikasi lapang dan studi pustaka diperoleh kegiatan ekonomi alternatif yang dapat dilakukan nelayan yaitu kegiatan penangkapan ikan di muara sungai dengan bubu, budidaya/pembesaran kepiting bakau, dan wisata sungai. Hasil FGD diperoleh masukan perlunya inovasi agar alat tangkap bubu tidak hilang saat arus sungai deras. Kondisi mangrove di Desa Jogosimo perlu dilakukan penanaman kembali agar populasinya lebih tinggi, sehingga budidaya ataupun pembesaran kepiting bakau dapat dilakukan. Rekomendasi yang dapat diberikan adalah perlunya mengembangkan wisata sungai melalui integrasi kegiatan penangkapan ikan, pemeliharaan dan pmbesaran kepiting bakau, serta wisata kuliner dan pemasaran produk lokal.

Umumnya perangkap krendet tradisional digunakan nelayan untuk menangkap krustasea dan dibuat dengan konstruksi sederhana tanpa dinding perangkap sehingga tidak ada fungsi melindungi hasil tangkapan dari predator. Solusi yang dapat dilakukan adalah merancang perangkap krendet dengan konstruksi bertingkat dengan dinding pelindung.  Hipotesis dalam penelitian ini adalah penggunaan perangkap krendet bertingkat akan meningkatkan hasil tangkapan krustasea.  Penelitian ini bertujuan untuk membuat rancang bangun perangkap krendet bertingkat sebagai perlakuan, membandingkan komposisi hasil tangkapan krustasea, menentukan pengaruh penggunaan krendet bertingkat terhadap hasil tangkapan krustasea, dan menentukan produktivitas perangkap krendet bertingkat. Penelitian dilaksanakan di Teluk Palabuhanratu secara experimental fishing selama 18 trip dengan menggunakan perangkap krendet bertingkat dan tradisional masing-masing 5 unit. Hasil penelitian menunjukkan bahwa krendet bertingkat mendapatkan krustasea sebesar 14,70 kg, sedangkan krendet tradisional sebesar 10,98 kg.  Konstruksi bagian atas krendet bertingkat memiliki pengaruh dalam meningkatkan hasil tangkapan sebesar 31,79%. Krendet bertingkat memberikan pengaruh nyata terhadap jumlah ekor dan berat hasil tangkapan.  Produktivitas krendet bertingkat lebih besar dibandingkan tradisional, yaitu masing-masing sebesar 0,82 kg/trip, 0,16 kg/unit dan 0,61 kg/trip, 0,12 kg/unit dengan kenaikan persentase rata-rata produksi krendet bertingkat sebesar 33,86%.

Pineapple peels are a potential food waste capable of being repurposed as a substrate for producing high-antioxidant probiotic beverages. Therefore, this study aimed to determine the feasibility of using pineapple peels as a substrate for producing high-antioxidant probiotic beverages through fermentation by Lactobacillus plantarum and Lactobacillus casei. Pineapple peels juice was fermented for 48 hours and the growth of microorganisms, reducing sugars, pH, titratable acid, polyphenol compounds, and antioxidant activity were periodically analyzed. The results showed that after 24 hours, the growth of L. plantarum and L. casei gradually slowed down. As fermentation time increased, the levels of reducing sugars and the pH decreased. L. casei reached the highest titratable acidity of 0.90% equivalent to lactic acid after 48 hours of fermentation, while L. plantarum reached 1.21%. The percentage of radical inhibition and phenolic compound increased between 9 and 30 hours of fermentation. The highest inhibition activity of 39% was achieved after 30 hours of fermentation for L. casei, while for L. plantarum, it reached 55% after 9 hours. This study showed that pineapple peels could produce probiotic beverages with high antioxidant. It was a suitable alternative for vegetarians or individuals who were allergic to dairy products.
