Platelet-poor plasma gel is a semi-solid plasma formulation that recently recommended as autologous bio-filler for treatment of atrophic dermal scars.

To compare the therapeutic efficacy and safety of intradermal injection of plasma gel in combination with fractional CO
laser versus fractional CO
laser alone in striae distensae (SD).

This study included 36 SD patients treated by three sessions (one session/1.5months) of fractional CO
laser on all SD lesions following intradermal injection of plasma gel on one side and saline (as placebo) on the other side.

Significant clinical improvements associated with remarkable narrowing of SD lesions and prominent enhancement of skin texture were observed on both treatment sides. Obviously, higher degrees of clinical improvements of SD lesions were reported following combined therapy with fractional CO
laser and plasma gel rather than fractional CO
laser monotherapy. However, post-inflammatory hyperpigmentation (PIH) was reported more frequently with fractional CO
laser monotherapy. Histopathological and immunohistochemical examinations revealed significant epidermal improvement, and homogenization, and orientation of dermal collagen bundles as a result of both therapeutic procedures.

Plasma gel in combination with fractional CO
laser could be considered a promising novel treatment modality for SD. Plasma gel not only improves the efficacy of fractional CO
laser but also decreases the frequency of PIH.

In particular, PRMT6 methylates histone H3 arginine 2 (H3R2) which affects both gene repression and activation. However, the substrate specificity of PRMT6 has not been comprehensively analysed. Here, we systematically characterise the substrate recognition motif of PRMT6, finding that it has broad specificity and recognises the RG motif. Working with a H3 tail peptide as a template, on which we made 204 amino acid substitutions, we use targeted mass spectrometry to measure their effect on PRMT6 in vitro activity. We first show that PRMT6 methylates R2 and R8 in the H3 peptide, although H3R8 is methylated with lower efficiency and is not an in vivo PRMT6 substrate. We then quantify the effect of 194 of these amino acid substitutions on methylation at both H3R2 and H3R8. Deruxtecan supplier In both cases, we find that PRMT6 tolerates essentially any amino acid substitution in the H3 peptide, but that positively charged and bulky residues are preferred near the target arginine. We show that PRMT6 also has preference for glycine, but only in the position immediately following the target arginine. This indicates that PRMT6 recognises the RG motif rather than the RGG motif. We further confirm this preference for the RG motif on another PRMT6 substrate, histone H4R3. This broad specificity and recognition of RG rather than RGG are distinctive among the PRMT family and has implications for the development of drugs to selectively target PRMT6.

The COVID-19 pandemic is having considerable impact on cancer care, including restricted access to hospital-based care, treatment and psychosocial support. We investigated the impact on unmet needs and psychosocial well-being.

One hundred and forty four participants (77% female), including people with cancer and their support networks, were recruited. The most prevalent diagnosis was breast cancer. Forty-one participants recruited pre-pandemic were compared with 103 participants recruited during the COVID-19 pandemic. We measured participants' unmet supportive care needs, psychological distress and quality of life.

Half of our patient respondents reported unexpected changes to treatment following pandemic onset, with widespread confusion about their longer-term consequences. Although overall need levels have not increased, specific needs have changed in prominence. People with cancer reported significantly reduced anxiety (p=0.049) and improved quality of life (p=0.032) following pandemic onset, but support network participants reported reduced quality of life (p=0.009), and non-significantly elevated anxiety, stress and depression.

Psychological well-being of people with cancer has not been detrimentally affected by pandemic onset. Reliance on home-based support to compensate for the lost availability of structured healthcare pathways may, however, explain significant and detrimental effects on the well-being and quality of life of people in their support and informal care networks.

Notably, we previously showed that alteration in mitochondrial activity was able to control the expression of keys regulator of cell cycle withdrawal and terminal differentiation. Here, we assessed whether inhibition of one of the respiratory complexes was a key factor in the regulation of myogenic differentiation in C2C12 cells, and was associated with alteration in reactive oxygen species (ROS) production. C2C12 cells were treated from proliferation to differentiation with specific inhibitors of mitochondrial complexes at a concentration that were inhibiting respiration but not altering cell morphology. Proliferation was significantly repressed with inhibition of complexes I, II, and III, or mitochondrial protein synthesis (using Chloramphenicol treatment), while complex IV inhibition did not alter myoblast proliferation compared to control cells. Moreover, inhibition of complexes I and II altered cell cycle regulators, with p21 protein expression upregulated since proliferation and p27 protein expression reduced at differentiation.
