Article Synopsis
  • The mitochondrial pyruvate carrier (MPC) plays a key role in connecting glycolysis to mitochondrial metabolism and its function in glioblastoma (GBM) post-treatment is not well understood.
  • Through in vitro and in vivo studies, the research shows that the MPC is crucial in regulating metabolism after treatments like temozolomide (TMZ) and radiation, specifically inhibiting differentiation in GBM cells.
  • The study highlights the potential for using MPC inhibitors to enhance the effectiveness of current therapies and improve survival rates for GBM patients.

The current investigation intended to assess the controlled delivery of 7-sulfonamide-2-(4-methylphenyl) imidazo[2,1-b] [1, 3] benzothiazole an anticancer agent (ACA) by tamarind seed gum-based hydrogel; for its potential activity against hepatocellular carcinoma. The FTIR spectra, SEM, C NMR, PXRD, and TGA analyses evidenced the successful loading of ACA into the hydrogel system. The rheological testing conveyed the increase in the elastic nature of ACA-loaded hydrogel helping in an effective release.

The cutouts of graphene sheets, particularly those with a nonplanar topology, present vast opportunities for advancement. Even a slight deviation from the planar structure can lead to intriguing (chiro)optical features for helically twisted nanographenes. In this context, we introduce two regioisomeric π-extended nanographenes that exhibit distinct excited-state characteristics.

High-resolution cryo-electron microscopy (cryo-EM) requires costly 200- to 300-keV cryo-transmission electron microscopes (cryo-TEMs) with field emission gun (FEG) sources, stable columns, constant-powered lenses, autoloader, and direct electron detectors (DED). Recent advances in 100-keV imaging with the emergence of sub-200-keV optimized DED technology promises the development of more affordable cryo-TEMs. So far, 100-keV imaging has required microscopes with FEG sources.

Several epidemiological studies have examined the respiratory consequences of occupational exposure to volatile organic compounds (VOCs). However, their effects on paint industry workers in organised and unorganised occupational sectors vary. The present systematic review and meta-analysis aim at evaluating the respiratory symptoms and pulmonary function of paint industry workers from various occupational sectors exposed to VOCs.

We present a case of tracheal necrosis due to mucormycosis in a young diabetic male. He presented with stridor due to airway obstruction from the necrosed tracheal wall. We used a silicon tracheal stent to maintain airway patency and support the airway.

Background: Prolonged cold storage (CS) of kidneys results in poor long-term outcomes after transplantation (Tx). We reported previously that CS of rat kidneys for 18 h before transplant impaired proteasome function, disrupted protein homeostasis, and reduced graft function. The goal of the present study was to identify the renal proteins, including phosphoproteins, that are dysregulated by this CS injury.

Acute exacerbations of COPD (ECOPD) are an important event in the life of a COPD patient as it causes significant deterioration of physical, mental, and social health, hastens disease progression, increases the risk of dying and causes a huge economic loss. Preventing ECOPD is therefore one of the most important goals in the management of COPD. Before the patient is discharged after hospitalization for ECOPD, it is crucial to offer an evidence-based care bundle protocol that will help minimize the future risk of readmissions and death.

Background: In the phase 3 JAVELIN Renal 101 trial (NCT02684006), first-line treatment with avelumab + axitinib resulted in significantly longer progression-free survival (PFS) and a higher objective response rate (ORR) vs sunitinib in patients with advanced renal cell carcinoma (aRCC). We report the final analysis, including the primary analysis of overall survival (OS).

Patients And Methods: Patients with untreated aRCC (any prognostic risk score) were enrolled.

Baculovirus is the most studied insect virus owing to a broad ecological distribution and ease of engineering for biotechnological applications. However, its structure and evolutionary place in the virosphere remain enigmatic. Using cryo-electron microscopy, we show that the nucleocapsid forms a covalently cross-linked helical tube protecting a highly compacted 134-kilobase pair DNA genome.

Issue Addressed: Food security is becoming increasingly difficult to achieve for many households. Research has shown that food insecurity is associated with socioeconomic disadvantage, including housing pressures, and may contribute to poor health outcomes. There is lack of data on these associations in the South Australian setting, where food security is not consistently monitored.

Anthracyclines, such as doxorubicin, are important anti-cancer therapies but are associated with arterial injury. Histopathological insights have been limited to small animal models and the role of inflammation in the arterial toxic effects of anthracycline is unclear in humans. Our aims were: 1) To evaluate aortic media fibrosis and injury in non-human primates treated with anthracyclines; 2) To assess the effect of anthracycline on aortic inflammation in patients treated for lymphoma.

Background: Malignant peritoneal mesothelioma (MPM) is a rare and aggressive form of cancer arising from the peritoneum. The prognosis for MPM has historically been poor, and treatment options are limited. This study evaluated the impact of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) as a treatment modality for MPM.

Children requiring veno-arterial extracorporeal membrane oxygenation (VA ECMO) or cardiac surgery often undergo cervical cannulation or carotid artery clamping, which can interrupt cerebral circulation. Inadequate collateral flow through the circle of Willis (CoW) may lead to cerebral ischaemia within the vascular territory and/or watershed regions. Pre-cannulation survey of the CoW using transcranial Doppler (TCD) ultrasound may be performed to predict and plan neuroprotection.

Dynamic susceptibility contrast (DSC) MRI is commonly part of brain tumor imaging. For quantitative analysis, measurement of the arterial input function and tissue concentration time curve is required. Usually, a linear relationship between the MR signal changes and contrast agent concentration ([Gd]) is assumed, even though this is a known simplification.

Nanographenes have captivated scientific interest since the pioneering discovery of graphene. Recently, attention has shifted towards exploring chiral and nonplanar nanographenes, for their distinct optical, chiroptical, and electronic properties. Despite the growing acceptance of helicenes, the research on inducing helical chirality on π-extended derivatives to boost chiroptical properties remains unattended.

Introduction And Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is one of the primary causes of chronic liver disease and may lead to liver cirrhosis and hepatocellular carcinoma. Recent reports suggested that DEAD-box RNA helicase (DDX3) acts as a sensor of free fat accumulation and may modulate the pathogenesis via miRNAs. Hence, we hypothesized that DDX3 might modulate MASLD progression via miRNA-141-mediated inhibition of Sirt-1 and autophagy.

Article Synopsis
  • Non-alcoholic fatty liver disease (NAFLD) is a major global health issue that can progress to more serious conditions like non-alcoholic steatohepatitis (NASH) and liver cancer (HCC), but the underlying molecular mechanisms are still not fully understood.
  • This study focuses on how microRNA-122 regulates pyruvate kinase M2 (PKM2) and its impact on inflammatory and autophagic proteins during NAFLD development using both cell cultures and animal models.
  • Results indicate that free fatty acids (FFAs) reduce miR-122 levels, leading to increased PKM2 and inflammation while suppressing proteins related to autophagy, highlighting the complex interactions that contribute to NA
