When 'the Happily Ever After Ends': The Grieving Process in Widowhoods.

The loss of the spouse causes several secondary losses, such as loss of family and individual identities, and for that, it is considered a risk factor for complicated grief. Our objective was to investigate the possible specific aspects of widowing. Data collection occurred via an online questionnaire, during the new Coronavirus pandemic and the mixed design (both qualitative and quantitative) research had the participation of 93 individuals. The loss of the spouse was considered the worst loss experienced by the participants. Loneliness, routine, bureaucracy, and rituals were the main difficulties, while spirituality, family, and work were mentioned as protective factors. Signs of complicated grief were associated with age and time since the death of the partner. There was no significant difference between gender nor between the type of death. The manifestations of widowing are similar to other forms of bereavement, but there are specifications that should be taken into consideration by professionals in order to promote quality of life.

The regions of the sequence most exposed to the solvent within the amyloidogenic state of a protein initiate the aggregation process.

Formation of misfolded aggregates is an essential part of what proteins can do. The process of protein aggregation is central to many human diseases and any aggregating event needs to be prevented within a cell and in protein design. In order to aggregate, a protein needs to unfold its native state, at least partially. The conformational state that is prone to aggregate is difficult to study, due to its aggregating potential and heterogeneous nature. Here, we use a systematic approach of limited proteolysis, in combination with electrospray ionisation mass spectrometry, to investigate the regions that are most flexible and solvent-exposed within the native, ligand-bound and amyloidogenic states of muscle acylphosphatase (AcP), a protein previously shown to form amyloid fibrils in the presence of trifluoroethanol. Seven proteases with different degrees of specificity have been used for this purpose. Following exposure to the aggregating conditions, a number of sites along the sequence of AcP become susceptible to proteolytic digestion. The pattern of proteolytic cleavages obtained under these conditions is considerably different from that of the native and ligand-bound conformations and includes a portion within the N-terminal tail of the protein (residues 6-7), the region of the sequence 18-23 and the position 94 near the C terminus. There is a significant overlap between the regions of the sequence found to be solvent-exposed from the present study and those previously identified to be critical in the rate-determining steps of aggregation from protein engineering approaches. This indicates that a considerable degree of solvent exposure is a feature of the portions of a protein that initiate the process of aggregation.

Ethics questions raised by the neuropsychiatric, neuropsychological, educational, developmental, and family characteristics of 18 juveniles awaiting execution in Texas.

Eighteen males condemned to death in Texas for homicides committed prior to the defendants' 18th birthdays received systematic psychiatric, neurologic, neuropsychological, and educational assessments, and all available medical, psychological, educational, social, and family data were reviewed. Six subjects began life with potentially compromised central nervous system (CNS) function (e.g., prematurity, respiratory distress syndrome). All but one experienced serious head traumas in childhood and adolescence. All subjects evaluated neurologically and neuropsychologically had signs of prefrontal cortical dysfunction. Neuropsychological testing was more sensitive to executive dysfunction than neurologic examination. Fifteen (83%) had signs, symptoms, and histories consistent with bipolar spectrum, schizoaffective spectrum, or hypomanic disorders. Two subjects were intellectually limited, and one suffered from parasomnias and dissociation. All but one came from extremely violent and/or abusive families in which mental illness was prevalent in multiple generations. Implications regarding the ethics involved in matters of culpability and mitigation are considered.
