Which leads me to add to my wholehearted endorsement of Gene’s call for libraries to make allowances for people to avoid play and games. The fact that family game night might, as Gene remarked, be a source of trauma is primarily an indictment of the state of those families – but given play’s links to health and the fact that games can heal and promote bonding and caring, it seems unwise to ignore the qualities of the games they are playing. It’s easy to take this as a joke – families fight over board games, oh well, It’s Only A Game – but if you dig even slightly into this, you find that some of these experiences are genuinely traumatic, as one would expect might be necessary to give someone a lifelong aversion to an entire medium. Monopoly is… as legendary for spawning bitter family fights and for dragging on interminably even though it’s obvious who’s going to win as it is for being widely played.

(H and I) Fluorescence images (H) and statistical data (I) showing that the M cell diveded in fed animals but remained undivided in 4-, 7-, or 11-d–starved L1 wild-type and mir-71(lf) worms. (E) Fluorescence and DIC images showing that the unc-31 3′UTR reporter was repressed in mir-71(+)worms (2/2 transgenic lines) but not in mir-71(lf) worms (4/4 transgenic lines). We found that the reduced survival rate of ain-1 was suppressed by either reduction of age-1 function or loss of unc-31 function (Fig. 1 B and C), suggesting that a significant portion of the overall miRNA functions in L1 diapause is upstream of, or in parallel to, the InsR pathway. Previous studies indicate that the InsR pathway plays a dominant role in regulating L1 starvation survival and that reducing the activity of the insulin receptor daf-2, the PI3Kinase age-1, or the upstream regulator unc-31 results in increased L1 starvation survival rate (2, 3). The two ain-1 loss-of-function alleles displayed significant reductions in L1 starvation survival rate. We found that ain-1 but not ain-2 mutants displayed a significant reduction in L1 starvation survival rate compared with that of wild type (Fig. 1 A and D).

  • (H) Fluorescence and DIC images showing that a lin-42 3′UTR reporter was repressed in mir-71(+) worms (2/2 transgenic lines) and prominently derepressed in mir-71(−) worms (2/2 transgenic lines).
  • We found that the poor survival rate of daf-16(mu86)(lf) was further decreased by mir-71(lf) (Fig. 2C), consistent with the notion that a portion of miR-71 activities regulate genes that act in parallel to UNC-31–mediated InsR/PI3K signaling for long-term survival during L1 diapause.

We further examined worms recovering from 4 d of L1 starvation and found that around 90% of the mir-71(lf) mutants displayed retarded vulval precursor cell (VPC) division, compared with less than 5% in wild type (Fig. 4A). In contrast, the nuclear-localized GFP expression under the control of the 3′UTR of age-1(Fig. 3 C and D) or unc-31 (Fig. 3 E and F) was strongly repressed in the control worms, but prominently derepressed in mir-71(lf) mutant worms. If the 3′UTR of age-1 or unc-31 is repressed by miR-71, the GFP expression will be repressed in tissues where miR-71 is expressed in wild-type worms, but derepressed in the same tissues of mir-71(lf) worms. Among short-lived miRNA mutants, a mir-71 deletion mutant, mir-71(n4115) (referred to as mir-71(lf) hereafter), displayed revery play a severe reduction in L1 starvation survival rate (Table S1 and Fig. 2A).

Knocking down lit-1 by RNAi in mir-71(lf); lin-42(lf) double mutants caused no significant suppression of the VPC timing defects of mir-71(lf) worms. To determine the functional relationship of miR-71 with LIN-42 and LIT-1, mir-71(lf); lin-42(lf) L1 worms were starved for 4 d and recovered on lit-1(RNAi) plates. The strong suppression of the mir-71(lf) defect by hbl-1(RNAi), and the relatively weak effect of miR-71 on hbl-1 expression, are consistent with the idea that miR-71 exerts its role by modulating activities of multiple genes related to hbl-1 function in developmental timing. We then compared the expression of a hbl-1 3′UTR reporter (18) in the mir-71(lf) mutants with that in wild type and found that the expression of this reporter was slightly derepressed at L3 in the mir-71 mutant (Fig. 4 F and G).
The reporter is strongly expressed in H and V cells in both wild-type and mir-71(lf) worms. Because miRNA-mediated gene silencing may cause translational inhibition or mRNA degradation or both (19), the relatively small increase of UNC-31 in mir-71(lf) animals was still consistent with unc-31 being a target of miR-71. To test whether the activity of the InsR pathway was down-regulated by miR-71, we first examined the endogenous expression of components of the InsR pathway in mir-71(lf). (C) The poor survival rate of daf-16(mu86, null) was enhanced by mir-71(lf).

  • Mainly the tone curve LAB settings and your color calibration is very confusing – how did you come up with this approach?
  • Mutating miR-71 drastically reduces the survival rate of animals in L1 diapause, and the effect can be suppressed by mutations of insulin receptor pathway genes age-1 and unc-31.

  • On one hand, we showed that deletions of a good number of miRNAs have varying impacts on the L1 diapause survival rate, although they may effect the rate through different mechanisms.

I recommend turning it off to see how it impacts this specific image. In normally exposed images, this method can lead to oversaturation, so I usually reduce it using other modules like Color Balance RGB. The LAB tone curve is mostly me experimenting to see how it affects color saturation, particularly in the Blue and Magenta spectrum, which I often adjust.

What are the stages of family recovery?

Furthermore, miR-71 plays a prominent role in developmental recovery from L1 diapause partly through repressing the expression of certain heterochronic genes. Here we show that compromising overall microRNA (miRNA) functions or mutating certain individual miRNAs impairs the long-term survival of nematodes during starvation-induced L1 diapause. But offering people opportunities to explore games and play in a safe, non-abusive, self-directed context like a library seems to me to matter, and for folks who are more likely than most to have social anxieties, finding those opportunities can be extremely hard. This certainly accords with the rise of therapists using games as therapy – a web search for “Dungeons & Dragons therapy” shows the recent explosion in ways in which people are finding healing in play. That means that when sales are up, more people are playing this and other older, less-fun games instead of games with the advantage of more than a century’s advancements in the art and science of play, including co-operative games, social games, nomic games, and more. The PlayStation Family app lets you manage your family from your mobile device, and offers additional options to monitor your children’s play time.

It helps maintain a balance where the family supports the recovering addict without enabling their addiction. Individual GFP reporter constructs for candidate genes (4 ng/μL) and the mCherry internal control plasmid (4 ng/μL) were mixed with unc-119 rescuing plasmid (20 ng/μL) and pBluescript KS+ (72 ng/μL) and coinjected into unc-119(ed3) and mir-71(n4115); unc-119(ed3) worms following standard protocols (32). To compare the survival rates between strains, we simulated the survival rate of each genotype to 100 arbitrary “individual worms” and performed the log-rank test in Graphpad Prism 4.

At festivals, the group shared the stage with acts like Casper, Distance in Embrace, and Rantanplan. The band was a support act for groups like Bakkushan, Callejon, Ohrbooten, We Butter the Bread with Butter, and Neaera. The band’s debut EP, Eskimo Callboy, was self-released in 2010 and was distributed via EMP. She has been reinventing her recovery since having children. A young people’s AA group in So CA allowed her to meet some great young people, and they partied without the alcohol. Her life became different when she let others help her and did what they said.
These models are used not just in clinical care but in recovery college programmes, self help groups, and community-based services across the UK. Peer support interventions are now recognised as valuable components of mental health recovery. This mix of professional oversight and personal connection helps create a balanced group dynamic where people feel supported emotionally and practically. This is when people who have faced similar mental health challenges share their stories and offer mutual encouragement. Over time, participants often find that being part of a group helps them build confidence, improve communication, and better understand their own needs in recovery.

Whatever the focus, the consistent thread is a sense of community and the reminder that recovery is possible. At Khiron Clinics, our group sessions often serve as a bridge between individual therapy and community-based support. These peer-led interactions are often supported by a therapist or group leader who ensures the space stays safe and respectful. It shows participants that their reactions and feelings are valid, and that recovery doesn’t have to be a solitary journey. That shared experience can be a powerful tool in breaking down feelings of isolation and self-blame.
