Parikh, A. R. et al. Liquid versus tissue biopsy for detecting acquired resistance and tumor heterogeneity in gastrointestinal cancers. Nat. Med. 25, 1415–1421 (2019). The soft and airy consistency of this hair mask alone makes it an absolute all-star. Unlike other contenders, it’s lightweight and blended right into our hair. It almost felt lighter and airier than our usual conditioner. In fact, on days we really wanted the mask to soak in, we saturated our strands with the product, then wrapped our hair up in a clip, letting it settle in all day. Although this mask has a watery gel consistency — a noticeable departure from traditional creamy masks — that’s also what allows it to be hydrating without being oily. It felt soft and lightweight as soon as we scooped the mask into our hands and didn’t feel too heavy when we massaged it through our hair.

As previous reports have demonstrated that tumor- and normal-derived cfDNA may be distinguishable from genomic DNA by fragment length 24, 25, we sought to confirm this observation in MSK-ACCESS data and use this information to better inform the origin of variants detected in cfDNA. The general fragment length distribution exhibited the expected bimodal cfDNA peaks around 161 and 317 base pairs, when factoring the trimming of 3 bases from read ends by the pipeline 26 (Fig. 4b). For all cfDNA fragments harboring a somatic tumor-derived mutation confirmed to be absent in WBCs ( n = 1558), we observed that these fragments were significantly shorter than those harboring the wild-type allele, consistent with their tumor origin (Fig. 4c–i) (bootstrapped p value < 0.0001). In several variants with limited supporting evidence in WBC DNA but significantly greater VAF in plasma cfDNA we were able to distinguish the origin as somatic tumor-derived (ctDNA) nature based on the slight cfDNA insert size profile peak in the WBC sample. As demonstrated in Fig. 4c -II, these reads did have a shortened fragment length (bootstrapped p value < 0.0001), confirming that they originated from the cell-free compartment. In stark contrast, the variant calls from the unmatched analysis that were filtered out as putative germline variants by their presence in WBCs at high VAF demonstrated an equivalent fragment length distribution as wild-type alleles (Fig. 4c -III) (bootstrapped p value = 0.94). As we have shown, by integrating the fragment length analysis into the MSK-ACCESS assay, we can confidently distinguish between tumor-derived somatic and normal-derived variants in cfDNA. Assessing the filtering of putative clonal hematopoiesis (CH) mutations Finally, to calculate specificity, variant calling was performed on 47 healthy donor plasma samples in comparison to their matched WBCs, and no mutations were called. In addition, we utilized the samples from the accuracy analysis with orthogonal NGS results ( n = 37), and considered all genomic positions interrogated by these assays ( n = 1620) (Supplementary Data 4). Four potential false positives not reported by the orthogonal NGS assay (TP53 p.R253H with VAFs 0.17 and 0.24%, and PIK3CA p.H1047R with VAFs 0.05 and 0.07%) were detected by MSK-ACCESS using genotyping thresholds, implying a specificity of at least 99.7% (95% CI: 99.3–99.9%). Through de novo mutation calling, we identified only one false positive mutation, for a specificity of 99.9% (95% CI: 99.6–100%). Overall, our positive predictive agreement (PPA) for genotyping was 94% (95% CI: 85–98%) and for de novo mutation calling was 98% (95% CI: 90–99.9%). The negative predictive agreement (NPA) was 99.7% and 99.2% for genotyping and de novo calling, respectively. Clinical experience—genomic landscape She suggests applying the mask from the ends up. And while most people tend to avoid the scalp when using a hair mask, Medchill says to go for it, unless your hair is fine, thin or prone to greasiness. “Scalp health is everything right now, so it’s ideal to use a mask on your scalp if you can,” she says.What We Love: This hair mask is at once hydrating and lightweight, so it will give fine or oily hair a boost of vibrance without weighing it down.

While cooling performance is absolutely amazing, thermals are only one part of the picture. How loudly the cooler runs is very important as well. In its default configuration, Lian Li’s GA II Trinity Performance runs loudly at 55.2 dBA. I’ve only tested a handful of coolers that reach this level of noise.
