Children with cancer can experience intense suffering. Currently, despite our best efforts, symptoms associated with both cancer and its treatment result in physical, psychological, and emotional discomfort that can be difficult to manage with traditional Western medicine alone. Developing integrative services within a pediatric hematology-oncology program may help improve cancer-related symptoms by combining different modalities targeting overall health with traditional oncology care. This study details the initia [...]

Telomere elongation is protective of genomic stability, whereas telomere shortening increases genomic instability and thereby increases cancer risk. Long telomeres lower the risk of clinical cancer, while short telomeres are part of a causal cascade of intracellular events that result in oncogenesis and, ultimately, clinical cancer. Telomerase therapy is not only unlikely to result in an increased risk of cancer but is likely to lower the risk of cancer compared to age-matched patients not treated with telomerase t [...]

Lambert Eaton myasthenic syndrome (LEMS) is a rare autoimmune neuromuscular junction disorder involving loss of functional pre-synaptic P/Q-type voltage-gated calcium channels. Many cases occur as a paraneoplastic disorder, often in small cell lung cancer (SCLC). Recently, immune checkpoint inhibitors (ICI) have emerged as treatment of choice for various malignancies. While generally well tolerated, certain ICI-treated patients experience neurologic immune-related adverse events (irAEs). Here, we explore therapeuti [...]

Huntington’s disease (HD) is an autosomal dominant disease that immensely impacts the affected families. However, the transmission of the disease from carriers to their offspring could be prevented. Prenatal diagnosis (PND) and preimplantation genetic diagnosis (PGD) are the only two available reproductive options for the carriers at risk to have disease-free children. PND for HD could be done through two kinds of genetic testing: direct and indirect. The same approaches are available for preimplantation genetic te [...]

The probabilistic formalism of quantum mechanics is used to quantitatively link the electroencephalogram (EEG) with the underlying microscale activity of cortical neurons. Previous approaches applied methods of classic physics to reconstruct the EEG in terms of explicit physical models of cortical neurons and the volume conductor. However, the multiplicity of cellular processes with extremely intricate mixtures of deterministic and random factors prevented the creation of consistent biophysical parameter sets. To a [...]

The Pd-H system has attracted extensive attention. Pd can absorb considerable amount of H at room temperature, this ability is reversible, so it is suitable for multiple energy applications. Pd-Ag alloys possess higher H permeability, solubility and narrower miscibility gap with better mechanical properties than pure Pd, but sulfur poisoning remains an issue. Pd-Cu alloys have excellent resistance to sulfur and carbon monoxide poisoning and hydrogen embrittlement, good mechanical properties, and broader temperature [...]
