The Idea of a ‘DNA Test’ for Transgender People Is Part of a Long, Dark History

Science is too busy holding the universe together to care about politics. Greenhouse gases will continue contributing to climate change and vaccines will continue not causing autism, whether you believe it or not. None of that means that politicians and ideologues won’t keep trying to drag science into their fights. The latest example of this unlovely truth occurred just this week, when the New York Times reported the existence of a memo drafted by the Department of Health and Human Services that would, if the changes it details were implemented, effectively roll back civil protections for transgender people by defining gender as a fixed biological trait, determined by genitalia at birth. The only exception, the memo reportedly states, would be if the male or female label could be “rebutted by reliable genetic evidence.” But, as decades of scientific research have shown, that kind of test does not remotely exist. It likely never will. It’s easy enough to determine basic physical sex with a quick scan for X and Y chromosomes. That can also determine some gender disorders, most commonly XXY—or a person who is superficially male, but carries an extra X, or female, chromosome. The condition, known as Klinefelter syndrome, can result in a range of problems, including delayed or incomplete puberty, comparatively weak bones and undescended testicles. X and Y chromosomes, however, tell you absolutely nothing about gender identity, which is a vastly more...

ConclusionThe CFQL-2 is a brief, reliable scale that effectively measures psychosocial aspects of QoL and is sensitive to changes in QoL in families of children with ASD or related neurodevelopmental disorders. Child externalizing behavior is strongly associated with reductions in multiple aspects of child and family psychosocial QoL.

Flujas-Contreras, Inmaculada GómezAbstractPsychological flexibility refers to the ability to be in contact with emotions, thoughts and feelings while behavior is directed at values. Psychological flexibility is considered to be a protective factor of health and psychological wellbeing, and includes six interrelated factors including; acceptance, values, committed action, contact with the present moment, self as context and defusion. The aim of this study is to assess the p...

ConclusionWithin the limitations of the study, GBR with or without autogenous block graft may be an effective approach in augmenting horizontally deficient mandibular or maxillary ridges, before the placement of dental implants. However, more complications may be seen with the use of an autogenous block graft related to the donor sites.

ConclusionThe authors recommended short implants whenever the height of available bone permits optimum implant placement. The authors concluded that both treatment options are considered viable clinically and radiographically. However, short implants have shown reduced postoperative discomfort, minimal invasiveness, and reduced cost.

In conclusion, this study presents the novel finding that the PVS periductium is composed of squamous MCs. These cells tightly line the luminal surface of the PVS tissue, including PNs, PVs, and small branches of the PVs in the abdominal cavity. These results will help researchers understand the role of the PVS in hyaluronan secretion, tissue repair, inflammation, and tumorigenesis, as well as the fine structure of PVS tissue.

Confabulation of a confused cardiologist Yes, It has never bothered me to retrogradely cross a delicately dangerous epicardial collateral in complex CTO. Delivering a twin stent in a partial culotte strategy for a bifurc lesion has never tested my talents. Stenting a left main across the LAD, jailing the LCX with OCT support is my favorite time pass. Crushing a calcium infested diffuse long lesion with diamond-tipped ablator appear as breezy as shopping in a mall. Oh …I am terribly upset with this damn thing.  What is that? It requires 4 negative forces . . . to bring one big positive Impact! These studies say ...

X-ray diffraction studies confirmed the amorphous nature of all the prepared glasses. The density and refractive index values of these glasses are evaluated using the Archimedes method and Abbe’s refractometer respectively. The values of density found to be in between 3.6363 and 3.6666 g/cm3. The refractive index values are observed in the range 1.5605–1.5620. An increasing t...
