13. Ciclones em Superfície nas Latitudes Austrais: Parte II Estudo de Casos
Resumo Esse trabalho apresenta a análise sinótica de quatro tipos de ciclones em latitudes austrais: extratropical do tipo Bjerknes e Solberg, extratropical do tipo Shapiro e Keyser, tropical e subtropical. Portanto, seu principal objetivo é destacar as diferenças entre esses sistemas e complementar, com análise sinótica de alguns casos, o artigo “Ci

14. Theoretical study of c-GaN/GaAs single heterojunction solar cells
ABSTRACT In this work a theoretical study of electrical behavior for a c-GaN/GaAs heterostructure as a photovoltaic device through a two-dimensional (2D) finite element numerical simulation is presented for a first time. I-V curves and electrical parameters like short circuit current (Isc), open circuit voltage (Voc), fill factor (FF) and efficiency (η) wer

15. Synthesis of Gallium Nitride and Related Oxides Via Ammonobasic Reactive Sublimation (ARS)
Ammonobasic reactive sublimation (ARS) is proposed as a novel method to synthesize GaN and related oxides. Results indicate that GaN growth occurs by a nitriding process of Ga and related oxides, establishing a direct dependence on NH4OH amount added as a primary chemical reactive. The samples were grown on p-type Si (111) substrates inside a tube furnace, e

16. Low-energy shock wave preconditioning reduces renal ischemic reperfusion injury caused by renal artery occlusion
Abstract Purpose: To evaluate whether low energy shock wave preconditioning could reduce renal ischemic reperfusion injury caused by renal artery occlusion. Methods: The right kidneys of 64 male Sprague Dawley rats were removed to establish an isolated kidney model. The rats were then divided into four treatment groups: Group 1 was the sham treatment grou

18. MicroRNA-340-5p modulates cisplatin resistance by targeting LPAATβ in osteosarcoma
MicroRNAs (miRNAs) play an important role in drug resistance and modulate the efficiency of chemotherapy. A recent study indicated that miR-340 functions as a tumor suppressor in various types of cancer. However, the role of miR-340 in chemotherapy has not been reported yet. In this study, we found that miR-340 enhanced cisplatin (CDDP)-induced cell death. I

19. Subversion of immunoproteasome subunit expression in dengue virus serotype 2-infected HepG2 cells
Abstract: INTRODUCTION: Infection with all serotypes of dengue virus (DV) results in augmented antigen presentation by MHC class I molecules. However, the upregulation of immunoproteasome subunits only results from infection with two serotypes. This study aims to elucidate changes in the expression of immunoproteasome subunits resulting from infection with

20. Pili canaliculi as manifestation of giant axonal neuropathy
Abstract Giant axonal neuropathy is a rare autosomal recessive neurodegenerative disease. The condition is characterized by neurons with abnormally large axons due to intracellular filament accumulation. The swollen axons affect both the peripheral and central nervous system. A 6-year old female patient had been referred to a geneticist reporting problems wi

21. Biological and therapeutic effects of honey produced by honey bees and stingless bees: a comparative review
ABSTRACT Honey is a natural product produced by both honey bees and stingless bees. Both types of honey contain unique and distinct types of phenolic and flavonoid compounds of variable biological and clinical importance. Honey is one of the most effective natural products used for wound healing. In this review, the traditional uses and clinical applications

23. Insulin Promotes the Expression of the Gluconeogenic Rate-Limiting Enzymes Phosphoenolpyruvate Carboxykinase (Pepck) and Glucose 6-Phosphatase (G6pase) through PI3k/Akt/mTOR Signaling Pathway in Goose Hepatocytes
ABSTRACT To identify what makes insulin have an activating or inhibiting role in gluconeogenesis in goose hepatocytes and whether insulin regulates PEPCK and G6Pase through the PI3k/Akt/mTOR pathway or not, goose primary hepatocytes were isolated and cultured in vitro. After 12h cultured in serum-free medium, hepatocytes were incubated for 24 h in the medium

24. Computed tomography findings of hepatic veno-occlusive disease caused by Sedum aizoon with histopathological correlation
This study investigated the value of computed tomography (CT) in the diagnosis and treatment of hepatic veno-occlusive disease (HVOD) caused by Sedum aizoon (SA). The clinical manifestations, treatment results, imaging findings, and histological findings of the liver were analyzed in 39 patients with HVOD caused by SA. Hepatomegaly, liver dysfunction, abdomi
