Background: Pembrolizumab is a monoclonal antibody targeting the programmed cell death protein 1 (PD-1). It is used in the management and treatment of various oncologic conditions. To name a few: refractory and advanced melanoma, non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), renal cell carcinoma and gastric cancer.

Human fibrinogen concentrate (Fibryga) received temporary approval for fibrinogen replacement therapy in France (2017), with subsequent full approval for congenital and acquired hypofibrinogenemia. We evaluated real-world use for on-demand treatment of bleeding and prophylaxis to enhance our knowledge on fibrinogen concentrate as an option for fibrinogen replacement. Data were retrospectively collected from adult and pediatric patients with fibrinogen deficiency.

Background: Lymphadenomas are rare benign tumors of the major salivary glands that are further classified as sebaceous and non-sebaceous. No association with viruses has been reported so far. Little is known about the mechanisms that allow lymphadenomas to undergo malignant transformation.

Unlike artificial nanosystems, biological systems are ideally engineered to respond to their environment. As such, natural molecular buffers ensure precise and quantitative delivery of specific molecules through self-regulated mechanisms based on Le Chatelier's principle. Here, we apply this principle to design self-regulated nucleic acid molecular buffers for the chemotherapeutic drug doxorubicin and the antimalarial agent quinine.

We present the precision measurement of 2824 daily helium fluxes in cosmic rays from May 20, 2011 to October 29, 2019 in the rigidity interval from 1.71 to 100 GV based on 7.6×10^{8} helium nuclei collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station.

We present the precision measurement of the daily proton fluxes in cosmic rays from May 20, 2011 to October 29, 2019 (a total of 2824 days or 114 Bartels rotations) in the rigidity interval from 1 to 100 GV based on 5.5×10^{9} protons collected with the Alpha Magnetic Spectrometer aboard the International Space Station. The proton fluxes exhibit variations on multiple timescales.

Background: Minimally invasive anatomic sublobar resection is increasingly being considered as an alternative to lobectomy in selected cases. However, this remains a technically challenging procedure and only 5 studies evaluating learning curves have been published to date. The aim of this study was to evaluate a single surgeon's learning curve for completely thoracoscopic anatomic sublobar resection.

Article Synopsis
  • This study analyzes the cosmic rays of sodium (Na) and aluminum (Al) within a rigidity range of 2.15 GV to 3.0 TV, using data from the Alpha Magnetic Spectrometer on the ISS.
  • The findings indicate that Na and Al belong to a unique cosmic ray group alongside nitrogen (N), showing similar flux behaviors.
  • The research establishes that both Na and Al fluxes can be explained by a combination of primary and secondary cosmic ray components, with the primary component becoming more significant at higher rigidities.

While P16 immunohistochemistry (IHC) is a well-established surrogate marker of Human Papillomavirus (HPV) in oropharyngeal squamous cell carcinoma (OSCC), Retinoblastoma 1 (RB1) loss may lead to p16 overexpression in the absence of HPV. We determined the proportion of p16-positive/HPV-negative OSCC with RB1 loss and other alterations in RB1/p16 pathway, and tested RB1 IHC as a prognostic biomarker for OSCC, along with the 8th edition of AJCC staging manual. P16 and RB1 IHC and HPV DNA in situ hybridization (ISH) were performed on 257 OSCC.

Precise knowledge of the charge and rigidity dependence of the secondary cosmic ray fluxes and the secondary-to-primary flux ratios is essential in the understanding of cosmic ray propagation. We report the properties of heavy secondary cosmic ray fluorine F in the rigidity R range 2.15 GV to 2.

Epithelial-myoepithelial carcinoma (EMCA) is a rare low-grade carcinoma of the salivary glands with multiple morphological variants. One such variant, sebaceous EMCA (SEMCA), has been reported in the literature. Distinguishing it from other tumors such as sebaceous carcinoma is crucial, as SEMCA typically behaves more indolently.

Objectives: Energy vessel-sealing devices are being increasingly utilized to seal pulmonary artery (PA) branches during lobectomy. Heat from these devices can potentially injure surrounding tissues. We evaluated heat production from devices in a live animal model.

In this article, we describe 2 high-stake diagnostic pitfalls that occurred in a single patient having undergone partial glossectomy and marginal mandibulectomy for invasive squamous cell carcinoma. Margins were grossly uninvolved. Histopathology showed a moderately differentiated squamous cell carcinoma.

Article Synopsis
  • - The Alpha Magnetic Spectrometer (AMS) conducted precision measurements of helium isotopes (^3He and ^4He) on the International Space Station, collecting data from 100 million ^4He and 18 million ^3He nuclei over six years from 2011 to 2017.
  • - The study found that the fluxes of both helium isotopes varied similarly over time, but the amount of variation decreased as the rigidity (energy per unit charge) increased.
  • - For the first time, researchers measured the rigidity dependence of the ^3He/^4He flux ratio, showing notable long-term changes below 4 GV but stable characteristics and a specific power law relationship above that threshold, aligning with other spectral indices in

The next generation magnetic spectrometer in space, AMS-100, is designed to have a geometrical acceptance of 100 m sr and to be operated for at least ten years at the Sun-Earth Lagrange Point 2. Compared to existing experiments, it will improve the sensitivity for the observation of new phenomena in cosmic rays, and in particular in cosmic antimatter, by at least a factor of 1000. The magnet design is based on high temperature superconductor tapes, which allow the construction of a thin solenoid with a homogeneous magnetic field of 1 Tesla inside.

Article Synopsis
  • Precision measurements of cosmic ray positrons up to 1 TeV were gathered by the Alpha Magnetic Spectrometer aboard the International Space Station, analyzing 1.9 million positrons.
  • A significant excess of positrons begins at around 25.2 GeV, followed by a sharp decrease above approximately 284 GeV, indicating a complex energy dependency.
  • The data suggests that at high energies, positrons mainly come from either dark matter annihilation or other astrophysical sources, with a notable energy cutoff of the source term established at about 810 GeV.
