Larvae of (the greater wax moth) are being increasingly used as a model to study microbial pathogenesis. In this model, bacterial virulence is typically measured by determining the 50% lethal dose (LD) of a bacterial strain or mutant. The use of to study pathogenesis, however, is challenging because of the extreme sensitivity of larvae to this bacterium.

Article Synopsis
  • * This report highlights how c-Myc activates lipid and serine metabolism, contributing to tumor development, while therapies like aspirin and lomitapide aim to disrupt these metabolic links to inhibit cancer progression.
  • * It also discusses various upstream regulators that affect c-Myc in different cancers, along with the potential impact of epigenetic pathways and non-coding RNAs on lipid and serine metabolism, suggesting new avenues for cancer therapies targeting these mechanisms.

The nonphysiological nutrient levels found in traditional culture media have been shown to affect numerous aspects of cancer cell physiology, including how cells respond to certain therapeutic agents. Here, we comprehensively evaluated how physiological nutrient levels affect therapeutic response by performing drug screening in human plasma-like medium. We observed dramatic nutrient-dependent changes in sensitivity to a variety of FDA-approved and clinically trialed compounds, including rigosertib, an experimental cancer therapeutic that recently failed in phase III clinical trials.

The non-physiological nutrient levels found in traditional culture media have been shown to affect numerous aspects of cancer cell physiology, including how cells respond to certain therapeutic agents. Here, we comprehensively evaluated how physiological nutrient levels impact therapeutic response by performing drug screening in human plasma-like medium (HPLM). We observed dramatic nutrient-dependent changes in sensitivity to a variety of FDA-approved and clinically trialed compounds, including rigosertib, an experimental cancer therapeutic that has recently failed in phase 3 clinical trials.

Printed circuit boards (PCBs) constitute an important segment of electronic waste that can be effectively utilized to recover valuable metals and organics. The present work is focused on the kinetics and product distribution from pyrolysis of three different PCB samples, viz., television PCB (TV PCB), motherboard PCB (MB PCB), and hard disk PCB (HD PCB).

Refuse-derived fuels (RDF) are rich in resources that make them an attractive feedstock for the production of energy and biofuels. Hydrothermal liquefaction (HTL) is a promising thermochemical conversion technology to handle wet feedstocks and convert them to valuable bio-crude, bio-char and aqueous products. This study highlights the advantages of using glycerol as the co-solvent along with water in different proportions to produce bio-crude from RDF via HTL.

Mycobacterium canariasense is a relatively newly discovered, rapidly growing nontuberculous Mycobacterium first described in 17 patients with fever in the Canary Islands, Spain, in 2004. To date, there have been very few case reports in literature, and to our knowledge, infective endocarditis due to M. canariasense has not been reported.

Introduction: Maxillary molars may frequently require root canal therapy and can have complex anatomy. It is important to locate and treat the second mesiobuccal canal to significantly improve prognosis.

Aim Of The Study: The purpose of this study was to evaluate direct vision, dental operating microscope (DOM), selective dentin removal under DOM, and cone beam computed tomography (CBCT) in clinical detection of second mesiobuccal root canal (MB2) in maxillary molars.

We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magnetic fields with ultracold neutrons. Our measurement stands in the long history of EDM experiments probing physics violating time-reversal invariance. The salient features of this experiment were the use of a ^{199}Hg comagnetometer and an array of optically pumped cesium vapor magnetometers to cancel and correct for magnetic-field changes.

Article Synopsis
  • The study analyzed the characteristics and treatment outcomes of 202 advanced lung cancer patients at a tertiary care hospital in Bangalore.
  • Data revealed most patients were male (134 out of 202), and adenocarcinoma was the most prevalent tumor type, found in 168 patients.
  • Survival rates varied, with a median progression-free survival of 6.5 months and an overall survival of 11.7 months, with specific treatments like nab-paclitaxel/platinum showing the best outcomes.

Recently, there has been an upsurge in the use of naturally available fuels for solution combustion synthesis (SCS) of nanoparticles. Although many reports suggest that these biofuels pose less harm to the environment, their strategic advantages and reliability for making NPs has not been discussed. In the present work, we try to address this issue using plant extracts as biofuels for the SCS of zinc oxide nanoparticles as a model system.

Background: Neuroendocrine tumors (NETs) are rare, heterogeneous, indolent tumors that are relatively insensitive to systemic chemotherapy. Therapeutic strategies for NETs broadly include somatostatin analogs, antiangiogenic therapy, and most recently, mammalian target of rapamycin inhibition. Combination therapy has shown promising antitumor activity and good tolerability in the randomized phase III trials.

We describe a spin-echo method for ultracold neutrons (UCNs) confined in a precession chamber and exposed to a |B0|=1  μT magnetic field. We have demonstrated that the analysis of UCN spin-echo resonance signals in combination with knowledge of the ambient magnetic field provides an excellent method by which to reconstruct the energy spectrum of a confined ensemble of neutrons. The method takes advantage of the relative dephasing of spins arising from a gravitationally induced striation of stored UCNs of different energies, and also permits an improved determination of the vertical magnetic-field gradient with an exceptional accuracy of 1.

We present a magnetometer based on optically pumped Cs atoms that measures the magnitude and direction of a 1 μT magnetic field. Multiple circularly polarized laser beams were used to probe the free spin precession of the Cs atoms. The design was optimized for long-time stability and achieves a scalar resolution better than 300 fT for integration times ranging from 80 ms to 1000 s.

Aim: The aim of this study was to evaluate the impact of admission anemia on in-hospital, one-month, and one-year mortality in patients from the Middle East with acute coronary syndrome (ACS).

Methods: Data were analyzed from 7922 consecutive patients admitted to hospitals throughout six Middle-Eastern countries with the final diagnosis of ACS, as part of Gulf RACE II (Registry of Acute Coronary Events II). Anemia at admission was defined according to the World Health Organization definition (<13 g/dL in men and <12 g/dL in women).

Methods: Thirty-five patients with first IWMI were studied and compared with 20 age-matched healthy controls, and categorized into those with (14 patients) and without (21 patients) RVMI based on standard ECG criteria.
