Background: Sex-determined differences are rarely addressed in the management of diseases, despite well-known contrasting outcomes between female and male patients. In COVID-19 there is a remarkable disparity, with higher rates of mortality and more severe acute disease in men compared to women, who are mostly affected by long COVID-19. Furthermore, whether androgens play a protective or detrimental role in COVID-19 is still a matter of debate.

Peripheral nerve injury in athletes is rare but deleterious to their performance, entrapment being one of the most frequent causes. Isolated injury to the superficial peroneal nerve (SPN) is rare and often underdiagnosed. The authors reported a clinical case of a 34-year-old handball athlete who presented with neuropathic pain in the inferolateral third of the leg and dorsum of the foot, with three months of evolution, after an ankle sprain, refractory to conservative treatment.

Understanding the dynamics of stability/plasticity balances during adulthood is pivotal for learning, disease, and recovery from injury. However, the brain-wide topography of sensory remapping remains unknown. Here, using a first-of-its-kind setup for delivering patterned visual stimuli in a rodent magnetic resonance imaging (MRI) scanner, coupled with biologically inspired computational models, we noninvasively mapped brain-wide properties-receptive fields (RFs) and spatial frequency (SF) tuning curves-that were insofar only available from invasive electrophysiology or optical imaging.

Novel therapeutic approaches are much needed for the treatment of osteosarcoma. Targeted radionuclide therapy (TRT) and radioimmunotherapy (RIT) are promising approaches that deliver therapeutic radiation precisely to the tumor site. We have previously developed a fully human antibody, named IF3, that binds to insulin-like growth factor 2 receptor (IGF2R).

Background And Purpose: The art of diagnosis in clinical neurology requires attentive listening and careful observation. In certain situations, a fragment of the history or a physical sign may be so distinctive that it allows clinicians to evoke a specific diagnosis. This quick mental process was previously referred to as 'Augenblickdiagnose' ('diagnosis in the blink of an eye') in a seminal paper by Dr.

Article Synopsis
  • Next-generation sequencing of pooled samples, called Pool-seq, helps scientists study genetic differences in populations but has some challenges like uneven contributions from individuals.
  • A new method called Approximate Bayesian Computation (ABC) has been developed to analyze this data better by taking into account the errors that come from Pool-seq.
  • Using this method, researchers examined the rocky-shore snails and found that two different types of snails formed before they spread to two nearby locations, suggesting that their differences are maintained even with some mixing between them.
